PAPER-ROLL HGLDER.

Application filed December 13, 1920, Serial No. $0,138.

To all whom it 'nmg (:0 a corn i 7 lie it lvnown that 1, Root: main M. Mad Conn-to, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful improvements in Paper- Tioll Holders; and I do declare the following to he a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it 'a ppertains to make and use the same, reference-being had to the accompanying drawings, and to the letters and iigu res of reference marked thcre on, which forms part of this specification.

This invention relates to improvements in roll holders wherein awound roll is placed upon a distributing core to be intermittently fed off therefrom. The invention is illustrated as applied to a toilet fixture in which. a roll holder or part is used to fit into the core of a paper roll and support the roll for use.

One of the objects of the invention is to provide an efficient, durable and inexpensive construction of paper dispensing means which will meet the necessary requirements of a device of the class described.

Among the difliculties heretofore encountered in the practical use of such devices is the ease with which the dispensing devices and the paper rolls can be surreptitiously removed, by unauthorized persons, from the supports to which they are initiallysecure-d.

An important objection to some types of such devices is that no provision is made whereby an attendant when calling at any time can remove intact a partially depleted roll and replenish the holder with a new roll because the core of the roll cannot be taken off the fixture until the roll is depleted. The attendant must either call again when the roll has been entirelydcpleted or must break the depleted roll to remove the same which damaged remnant is then. frequently thrown away, resultingin waste.

A more serious objection in other types is that so-called foreign rolls may he substitute-d for the one designed to be used with the dispensing device, which substitute rolls are often of poor quality and of unsuitable 'duction oi unauthorized paper texture, resulting in trouble and dissatisfaction. 7

An annoying objection in certain types of existing devices is that the endsof successive sheets to bedetached from the roll will be "found stuck to the iiace of the roll instead of hanging down free and clear and ready to be sped;

Y A further objection is that in some types the paper rolls have large notches or openings in their ends surface which mar the roll and nialreit present afldisfigured appearance. j

My invention contemplates the provision of means whereby all these objections are overcome and desired objects accomplished, and I "have also provided means whereby uniform quantities of the paper will be dispensed intermittently,

Means is also provided for generally improving the arrangement, construction and operation of devices of the class herein in volved and these features will become apparout by reference to the following description in connection with the accompanying drawings, in which Fig. 1 is a perspective view of one form of a1 dispensing device constructed in ac cordance with my invention.

F 2 is a plan view of the same, the Wall bracket plate being shown in section;

Fig. 3 is a detail perspective view of a. loclcguard for locking the roll holder and the roll together and for resisting the introrolls upon the dispensing device.

Fig. 4% is a detail perspective view of a paper roll engaging lock guard having somewhat similar functions to the oneshown in Fig.

Fig. 5 is a vertical, longitudinal, sectional view through a device constructed inacco-rdance with my invention, with the paper roll applied and also shown in section.

Fig. 6 is a sectional view on the line 6-6 of Fig. 5, looking in the direction indicated by the arrows. Q i f Fig. '7 a diagran'lmatic view of the paper roll ready to be applied to the dispensing device. i

Fig. 8 is a. diagrammatic view of the paper roll showing the position of the perforations or slits after the outer plies have crept, due to the pull on the paper and to the momentive jar of the holder and roll.

Fig. 9 is a similar view showing the position the paper roll would tend to assume as a normal position after each determined length was dispensed from the roll.

Fig. 10 is a similar view showing the position the severance perforations assume in actual practice, and

Fig. 11 is a detail perspective view of a device that may be employed for separating the axles and the elements of the split mandrel or core upon which the roll may be mounted.

Thegeneric novel, feaures as well as the specific details of construction of sutlicient importance will be specifically described hereinafter. I

In the drawings I have shown a base plate 1. which may beprovided with a peripheral flange 2, if desired, although the plate may be made of relative thick material, in which event the flange 2-may be dispensed with. Outstanding arms 3 and 4 are hinged to the respective ends of the plate 1 and terminate in bearing boxes 5 and 6, formed by bending the ends of the arms back upon themselves I in substantially rectangular form, as clearly apparent by reference to Figs. 1 and 2, so that double bearings are provided on each arm for one of the respec tive axle members of the mandrel or core which supports the paper roll.

If the arms 3 and 4 are formed of sheetmetaL-I prefer to strike out the metal at the bottom of at least one bearing of each arm, for example, as at 7 in Fig. 5. so as to provide a rest or relatively broad bearing face for the axle which it'supports. The bearing openings in the inner walls of the bearing boxes are given an upward elongated form so as to allow passage of the curved axle ends in order to be initially affixed to the respective mandrel drums described herein after. i

The axles, it will be observed, project through the bearing portions 8 and 9 for the box 5, and 10 and 11 for the box 6 and the axle members 12 and 13 are shown as provided with heads 12 and13 respectively at their outer ends, while their inner. ends are. oppositely curved and have recess shoulder-engaging portions 14 and 15. the adjacent faces 16 and 17 being curved so that when the two parts are brought to gether, they will slide one upon the other and cause the shoulders 18 and 19 to interlock, as shown in Fig. 2.

The axle members carry mandrel heads 'or drums 20 and 21 which, in conjunction with the axles. constitute a core or mandrel upon which the paper roll is to be mounted.

The mandrel members 20 and 21 are provided with flanges 22 and 23 to abut against the ends of the paper roll to be hereinafter referred to and the flanges 22 and are provided with outstanding, resilient projections or lips 24c and 25, which are adapted to contact with the resilient, inwardly projecting lips or lugs 26 and 27 on the arms 3 and a so that when the mandrel and paper roll have been rotated through a determined arc, the lips or projections 24 to 27, both inclusive, will act as yielding stops to pre vent further rotative movement and also to provide safety stops for flat springs 30 and 31 provided within the boxes 5 and 6 and secured thereto, against which the pins 32 and 33 on the axles 12 and 13 may rub as the axle members or shafts are rotated, the spring frictionassisting to retard the rotative movement of the weighted mandrelor core as the length of the paper to be torn off begins to reach the limit of its unwinding movement, and which pins must not be permitted to get altogether pastthe ends of the flat springs which would block the return movement. To actively assist inthe return movement and to position the roll so that the line of perforations will be yieldmgly advanced to a point beyond the line of perpendicular regardless of the center line of gravity as would be established by the weight alone and so that the loose end of the sheet will always drop down from the surface of the roll ready to be grasped for use ,and also to position the mandrel sea-tions 20 and so that when not supplied with a roll, they will always rest with the roll guide posts 34- and turned to the top somewhat toward the operatorand, therefore. in. position. to readily engage with the roll end slits 36 and 37 when applying the roll, the boxes 5 and G are rovided with coil springs 38-and Fla-respectively which are wound about the journals of the axle members 12 and 13. one end of each spring being secured'toan axle member and the other to a. hearing end 5 or tl, the case may be.

It is desirable to maintain the axle members 12 and 13 in substantially axial alignment to insure perfection of operation and to this end I prefer to provide stop members consisting of inwardly projecting lingers l0 and 4:1. which are carried by the arms 3 and 4 and which are adapted to rest against the flat faces of the bolt heads 42 and 43 so that when the axle members 12 and 13 are locked together within the paper roll which the mandrel supports, an unauthorised person may not-turn the bolts The plate 1 carries asubsta-ntially U- shaped hanger 14, the ends of which project through perforations in the plate 1 and have offset portions by which they are secured thereto, the hanger 44; being for the purpose of holding the nearly depleted roll or portion of a, roll which has been removed preparatory to introducing a new roll upon the mandrel or drum members 20 and 21.

As heretofore explained, it is desirable to provide means whereby the paper roll cannot be surreptitiously removed from the holder by an unauthorizedperson and also whereby an unauthorized or foreign roll may not be used in connection with the dispensing device or roll holder forming the subject matter of this invention, and to this end I have provided a novel construction of lock-guards which are adaptto be carried by a core or mandrel member and which willlock with the roll at the interior and will prevent the roll and one mandrel section from being turned in an opposite direction from the other mandrel section to disengagethe axle endsto unlock the same, and these lock-guards will also oppose the introduction of any roll except one especially designed to be utilized in connection with the mechanism herein disclosed.

When so desired lock-guards can be made a part of or be immov ably afiixe'd to the inner faces of the mandrel heads and have a roll-recess-engaging locking part projecting rigidly above the peripheral surface of the heads, when to apply a roll to the first mandrel section the roll may be tilted sufficiently for the projection to be received .into the roll recess, whenthe roll and both mandrel SGCfiODSCzIIitlIBII be turned about 90? to the rear and the opposite mandrel head can 'thenflbe inserted at an angle which will allow its projection to enterthe recess in that end of the roll. Both sections can then be pressed together until the interlockingsections will have become overlapped and locked. 1

One form of preferred roll-actuated camlock-guard is bestsho'wn in Fig. 3 as consisting of a plate 45having a lifting part, shown as a cam flange 46 at one end and a recess-engaging portion 47 at the other, the cam flange 46 and the recess 'engaging portion a? being capable of raising out of interfering position with respect to theroll be visible nor readily accessible after the end slit 36 to receive the centering finger or blade 34 which maybe carried by a web portion 52 as part of the plate 45, and provided to determine the position of the roll so that the perforations' can be placed only to the top with the recess a9 unfailingly in line to receive the" recess-engaging portion 47, and if desired, a guard 53 may be struck up from the plate and provided with a depending linger 54. which, when the lock-guard plate 45 is in the position shown in Fig. 1, will drop back of the shoulder 18 on the axle member '12 so that when the arms 3, and at are swunginwardly, the parts 18 and 19 cannot lock, the guard finger 51 being movable ont of obstructii'ig position only when the plate is lifted and since the lifting can only be accomplished by a roll constructedsimilar to the one designated 48 in Fig. 5, it is obvious that an unauthorized roll of paper cannot be successfully employed, but it isapparent that even without the plate 45 having the depending linger 54:, the recess-engaging portion d7 and the cam flangefi will still exclude any roll not provided with internal recesses.

In the illustrated embodiment of my invention shown in Fig. 1, the recess-engaging blade or finger 17 is shown as projecting through a slot in the end face of the mandrel member or drum 20, the lug 53 projecting through an opening 56' in the end face. and the centering or alignlng linger 3a projecting through a longitudinal slot 56 in the perimeter. of the mandrel niemher 20. i The cam flange t6extends through a corresponding opening 57 in the perimeter of the member 20 and substantially" diametrically opposite to the slot 56.

Fig. a shows'another form oflock-guard for use in {the opposite mandrel se tion which carries the "weight, and the iOlliS is provided with a recess corresponding to the recess 49 to receive the roll engaging portion 4.7. This opposite recess may be engaged by a swingable-lock-guard shown as consisting of aplate having side edge flanges 59and 60 with. aligning perforations (31 and 62, which are adapted to receive a hinge or pivot member 63 whichpr'ojects through the down-bent flanges 64; and 65 struck out from the peripheral surface of the member 531. upstanding flange 66 atone endand a recessengaging finger 67 at tlie()ther,the recess-engaging finger 67' being shown as The pivoted plate has an a slot 66' which is engaged by the guide projection 35 struck inward from the mandrel flange 23 and .provided to strengthen the swingable-lock-guard 58 and provided also to engage the roll end slit 37 to position the roll so that the line of perforations can be placed only to the top with the recess 5O unfailingly in line to receive th recess-engaging finger,67.,

Vhen the mandrel member is being-insertedinto the core 68 of the made-up roll 48, the swingable lock-guards 58 will assume the position shown in Fig. 1, but when the member 21 has been introduced far enough so that-the edge of the roll 18 contacts with the flange 66, the lock-guard 58 will he tilted into locking position as shown in Fig. 5, with theflange 66 resting in the plane of the mandrelflange 23, allowing the roll to enter fully onto the mandrel 21, but if a roll of improper construction were applied, then 'the swingable lock-guard 58 couldnot take its proper position with the result that the roll would not be permitted to enter fully onto the mandrel and conse quently the axle parts 18' and 19 could not be brought together sufficiently to overlap and lock, and the whole would be inoperative. i

If'a roll of properconstruction is thus placed upon the mandrel or core members 20 and 21 and the arms 3 and 4: are swung inwardly, the locking engagement of the parts 18 and 19 will be unopposed and they will move into theposition shown in Fig. 2, the roll protecting the locking members 18 and 19 from access because as soon as there is'a pull upon the free end of the paper, there will be a slight creeping of the paper about the axis of the roll whereby the slits 36and 37 and the slitted perforations will become somewhat staggered or overlap the corresponding slits in the inner layers of the roll so that the perforations and slits will assume the positions shown in Figs.,8, 9 and 10. Therefore, it

will be impossible to introduce a tool through the roll topry the locking ends 18 and 19 apart, itbeingunderstood that the slits 36 and 37 and slitted perforations 69 originally assume aligning positions, as

shown in Fig. 7, but as soon as tension is placed upon the paper, they assume .the positions shown in Figs. 8, 9 and 10.

lVhen the pull isexerted on the loose end of thepaper roll, the :entire mandrel consisting of the axle members 12 and 13 and the members 20 and: 21, together with the roll, will be given a partial rotative movement against the action of the coil springs 38 and 39, the tensions of the springs increasing as thecoils are wound and further resilient retardationbeing offered by the contact of the fingers 32 and 33 against the fiat springs 30 and 31 until the resilient lingers 24 and 25 come in contact with the resilient fingers 26 and 27 whereupon the paper will be severed in pro-determined lengths, whether one sheet or more.

As soon as the paper is severed, the recoil springs will movethe parts back to normal position as shownin Fig. 1. e

In some instances'it may be desirable to have an over-balance weight in at least one of the members 20 or 21 and for convenienceaI prefer to place the weight in the member 21 and so dispose it with relation to the center of gravity that the inertia of the weight, together with the return effect of the coil springs will be sufficient to cause the mandrel or drum member to over-recoil enough to bring the line of severage, as indicated at 71 in Fig. 10, slightly beyond a vertical line 72 drawn through the axis of the roll,.thus insuring that the free end of the paper will always drop, ready to be grasped when desired.

, Under. certain conditions, however, the weight. may be dispensed with for it is possible to design the coil spring so that the over-recoil will be sufficient to drop the sheet.

,When a roll has been depleted about two thirds or more and the layers of sheets have been torn off in use down to a point. below the overlapping of the perforations indicated by the diagonal line, 76, the attendant when calling at any time to replenish and, without having to wait until the roll has been entirely used up, can proceed to remove the remnant by inserting a special wedge end tool through the perforations 69 down into the open space between the axle terminals 14 and 15' to pry them apart to disengage, and when using the'fixture with the mandrel sections swung into position at right angles to the back, of the bracket and with the left mandrel supporting a depleted roll and the right mandrel supporting another partly used or a full roll, both. rolls with their respective mandrels can be revolved at the same time without slipping, and the remnant from the depleted roll can be saved instead of thrown away and can be rewound upon the outside of the'partly used or full roll, and when this process is finished and the discard roll core is removed, the rewound roll can be swung into the aligned position and locked in place for use as above described, but

if preferred, the remnant can be hung upon,

tion of tool selected for illustrative purposes is shown as consisting of a shank 73 having a blade portion 74: and a handle or eye 75. The tool is so constructed that when the roll is about depleted and the slits 69 in all of the sheets are in alignment, the blade 7d may-be inserted through them and between a curved edge 16 or 17 and a shank of an opposing axle member so that the tool may be manipulated to force the engaging ends of the axle members apart in an obvious manner. By reference to Figs. 1 and 2, it will be seen that the projections 25 are struck up from the metal ends 22 and 23 so that they provide notches, the inner edges of which areco-incident with the drum perimeters 20 and 21. Therefore, the amount of paper remaining upon the roll can be at all times determined by observing from either side of the drum heads.

My invention and the usefulness of same as thus described in this example is clearly disclosed and it is evident that construction may be modified without departing from the spirit of my lnventlon and 1,

therefore, do not limit myself to the pie (1S8 structure shown and described.
