WINDING MECHANISM FOR EMOSSING AND PRINTING PRESSES.

Specification of Letters Patent.

Patented rune 29, 1909.

Original application filed March 31,1908, Serial No. 424,808. Divided and this application filed June 29, 1908. Serial r70. 140,798.

To all whom it may concern.- v

Be it known that I, CHARLES E. BROOKS, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Winding Mechanism for Embossing and Printing Presses, of which the following is a specification.

The subject-matter of the present invention is divided out of an application for Letters Patent for improvements in embossing and printing resses, Serial No. 424,308, filed by me on i arch 31, 1908.

The resent invention relates to the mechanism or winding waste paper and has for its principal ob'ects to insure the taking 11 of the slack of t e'paper, toengage the win ing drum and the actuating mechanism by a connection that will automatically yield when the aper is stretched taut, to provide for the coiia sing of the winding drum, and to secure other advantages hereinafter ap pearing.

It consists in the construction and arrangement of parts hereinafter described apd claimed.

In the accompanying drawing, which forms part of this specification and wherein like symbols refer to like parts wherever-they occur, Figure 1 is a vertical sectional view of a winding mechanism embodying my-invention; Fig. 2 is a detail View of the gear and its clutch element; Fig. 3 is a cross section of the winding drum on the-line 3-3 of Fig. 1; Figs. 4 and 5 are cross sectional views taken on the same plane but looking in tip posite directions, as indicated by the arrows in Fig. 1.

My winding mechanism is supported upon any suitable device. In the accom anyin drawing, it is illustrated on a b' urcate bracket 1 provided therefor on the frame of ;an embossing and printing press, and its relation to the other partslof such press are more fully shown and described in my 00- pending application .No. 424,308 above mentioned.

The shaft or core 2 of In windin drum is journaled in horizontal ubs ,or bearings provided therefor in the arms of the bracket. liotatably journaled on this shaft or core between the arms of the bracket is a gear or pinion 3. Meshing with this pinion is a rack A which is adapted to be reoiprocated by any suitable mechanism, as for instance, the

' mechanism illustrated in said application No. 425L308. One end of the pinion bears against an arm on the bracket and the other end is widened into an annular flange 5 upon Whose face are mounted a series of gravity awls 6 and limiting sto )S 7 therefor.

oosely journaled on said shaft or core of the winding roll in the plane of said gravity pawls is a ring '8 whose periphery is toothed to forina ratchet wheel ada )ted to cooperate with said gravity pawls. A similar toothed ring or ratchet wheel 9 is'keyed to the core or shaft of the winding drum'alongside of said first mentioned ratchet wheel. These two ratchet wheels constitute members of a friction clutch. Above and-in the plane of said fixed ratchet Wheel are a plurality of gravity pawls 10 which are mounted on a plate 1 which is secured by pins or otherwise to the bracket 1 which supports the winding drum.

The tubular core or shaft 2 of the winding drum has peripheral slots 12 through which projects a plate 13 which bears against the side of the first mentioned ratchet wheel or clutch member 8 for the purpose of lessing it into frictional engagement with t e fixed ratchet wheel. This plate or cross iece has a hole therein through which extenr s the reduced end of a rod 14 Whose outer end rests in the bore of a hollow nut 15 which is threadedto work in the threaded end of the hollow core of the winding ro'll. In the bottom portion of the bore or pocket of said not is a spring 16 which presses against the end of said rod. The projecting end of the nut is provided with a knurled head or handle '17 whereb' 'it can. be conveniently manipulated. y turning the not, the pressure of the s rin upon the rod is varied, and thereby t he riction between the clutch members 8, 9 is varied.

On the core. of the winding drum are mounted a plurality of cylindrical segments 18, which are connected to the core by means of parallel links 19. The outward movementof the links-is ,limited'by' a collar 20 provided on the core for the ,urpose. The segments are supported in t eir extended position by .means of a flanged sleeve 21 whose inner portion is adapted to fit on the core of the winding roll and whose .pro-

jecting end is formed into a. handle 22 for convenient manipulation. Obviously, the withdrawal of this flanged sleeve ,or 'plug permits the segments to be collapsed and the waste paper to be Withdrawn from the roller drum. 7

The 0 eration of the winding mechanism is as fol ows: The reciprocating movementof the rack bar 4 causes a forward and backward movement of the inion 3 and of the pawls mounted on the ange thereof. The forward movement of these pawls causes a forward movement of the rotatable ratchet wheel 8 which constitutes the movable member of the friction clutch. On account of the frictional engagement of the clutch members, the rotation of the first member tends to rotate the second member of the clutch and consequently the core or shaft seems said core adapted to fit inside of said segments when the links bear against said sleeve.

3. A winding drum comprising a core, a pinion sleeved thereon, pawls mounted to move with said pinion, a ratchet wheel swiveled on said core in o erative'relation tosaid pawls, a second rate et wheel fixed to said core, stationary pawls in operative relation to said last mentioned ratchet wheel, and means for frictionally engaging said ratche wheels with each other. 4. A winding mechanism comprising a collapsible Winding drum having a core, and a friction clutch member fixed to said core, a

second friction clutch member loosely mounted on said core in operative relation to said first mentioned clutch member, actuating mechanism operatively connected to said second friction clutch member, and means for reventing backward movement of the Win ing vdrun the clutch t is to sa .e multi e 1t ratc et no two of at at the .e of them unwinding a core, a allel links rents, and Fsaid core, ute an in segments hdrawable 1e collapsa core, a' s connectsleeve on novement ounted on ontitrem smitiinrt om'g em anti/n flee sec,-

6. A win ing mechanism comprising a winding drum having a hollow. core having slots in its periphery, a ratchet wheel fixed on saidcore, a stationary pawl in operative re-. lation to said ratchet wheel, a second ratchet wheel loose .on said core, a pinion loose on I said core and having pawls arranged to engage said last-mentioned ratchet wheel, a

rack meshing with said pinion, a rod in said core having members projecting through the slots therein and arranged to bear said lastmentioned ratchet wheel against said firstmentioned-ratchet wheel, and a nut in the end of said core havin a s ring arranged to bear against the end 0 sai rod and thereby vary the pressure of one, ratchet wheel against the other.

provided for the driven member of are located to operate serially, tha instead of being spaced apart som of the distance between adjacel teeth, they are so positioned that them are in operative engageme same time, and, consequently, on is in position to prevent the least i of the roll.

While I have described my dev plied to an embossing and printin; the purpose of winding waste wip it is obvious that the invention is application for winding sheets of other materials that are fed inter So, too, it is obvious that the n hereinbefore described admits of able variation without departing invention, and I do not wish to be to such specific mechanism.

What I claim is:

1. A winding drum comprising plurality of spaced segments, par connecting said core and said segn I a plug mounted to move endwiseol 50 r said core being ada ted to constit ternal support, for t e ends of said but being independent of and wit] from said segments to facilitate tl ing thereof,

2. A winding drumcom rising pluralit of segments, para el link
