Slots 19 are formed in these wall formations for the passage therethrough of the depending, parallel, front and back sections 20 and 21, respectively, of the web loop L.

As shown more particularly in Fig. 4, the interior of the cabinet includes a vertically extending, channelshaped, reenforcing and supporting member comprising vertically extending, transversely spaced side panels 22 which have their rear edges merged into a uniting back panel 23 placed directly against and secured to the rear wall 12 of the cabinet. The forward vertical edges of the side panels 22 terminate in outturned flanges 24 which are suitably secured to the inner face of the front Wall 11. The lower portions of the side panels 22 are inwardly recessed to correspond with the inwardly offset region of the cabinet front.

Mounted in registering order on the inner faces of the side panels 22 are stationary supporting and guiding brackets 25. Each of these brackets comprises in this instance a at, metallic plate which is welded, or otherwise fastened, in a secure, stationary manner on the inner face of one of the side panels 22 at a position directly opposite to, and in transevrse registry with, the other complemental bracket on the opposite side panel. Each bracket plate is recessed as shown at 26. The lower edge of each of these recesses is arcuately flanged at 27, the inner end of each flange terminating in an axlejournalling seat 28 disposed at the closed end of each recess 26. The outer or open end of each recess 26 provides a vertical downwardly extending passage 29, each of which being open at the bottom thereof, as shown in Figs. 6 and 7, each passage having spaced, parallel, vertical sides.

The outer side of each of these passages is formed by inwardly and laterally offsetting each bracket at the front thereof at 30 to provide an anvil flange 31, the purpose of which will appear presently. Above and in registry with the flange 31 each of said brackets is formed with an inwardly projecting and downwardly directed bearing seat formation 32 which is separated from the upper end of the iange 31 by the outer region 26' of the recess 26 of each bracket.

An active roll 33 composed of spirally wrapped web 34 of fabric toweling is supported for rotation in the casing by the provision of an axle rod 35. This rod is removably inserted in a selvage hem 36 formed in the inner or trailing edge 37 of the web 34. The rod extends axially of and through the roll and, as shown in Fig. 4, has its opposite ends positioned for rotation in the journal seats 28 of the brackets 25. The latter, in this instance, are formed with localized outwardly recessed regions 38 which occupy slots 39 in the side panels 22, the regions 38 being so formed and disposed as to permit the roll 33 to be bodily lowered in the cabinet with the axle rod inserted therein without bracket interference and to maintain gravitatonally an operative position in the seats 28.

The outer or leading edge or end of the roll web 34 is trained downwardly and outwardly, as shown in Fig. l, the web passing through the slot 19 in the angular wall formation 18 of the cabinet and producing there below the depending loop-forming region L, by which fresh Unused areas of the web may be presented to patrons as the web is removed from the roll.

In preserving the form of the loop, the back section 21 thereof is passed upwardly to extend through the slot 19 in the horizontal formation 17 of the front cabinet wall and from this slot the web 34 passes between the somewhat loosely intermeshing teeth of a pair of lower web-feeding gears 39a of rubber or other yieldable material. The gears carry axial shafts 40 which have their end portions journaled in bearing openings provided therefor in plates 40a secured to the panels 22. One of these axles carries a sprocket around which is trained an endless chain 41. This chain is also trained over a complemental sprocket fixed to the outer end of one of a pair of upper gear-carrying shafts 42.

Fixed on the shafts 42 is a pair of upper web-feeding gears 43 of resilient composition. The latter gears contact opposite sides of the roll web 34 at a position between the roll 33 and the slot 19 of the wall 18. It will be seen that by drawing downwardly on the outer section 20 of the looped portion of the web, the latter will be removed from the roll and advanced in the direction of the arrow a of Fig. l. Such linear movement of the web produces rotation of the upper set of rubber gears 43, and through the chain and sprocket drive 41, corresponding rotation of the lower set of gears 39a.

By these means the length of the loop L is continuously maintained. The soiled or used webbing, after passing through the lower set of gears 39a, drops into a compartment 44 formed to receive the same, and from which the soiled webbing may be removed from timeto time for laundering and re-rolling purposes. A pivoted detent 45 is carried by the back panel 23, the front end of the detent having gravitational engagement with one of the gears 39a to restrict the rotation of these gears to the web-feeding directions indicated by the arrows b in Fig. l. The ends of the shafts 42 are received in bearing openings formed in plates 42a carried by the panels 22.

In order to construct the apparatus so that it may receive therein a reserve roll 46 of the toweling and to couple automatically the trailing edge 37 of the web 34 of the active roll 33 with the leading edge 47 of the web 48 of the reserve roll, the upper edges of the side panels 22 are provided with slotted journalling seats 49. Adapted to occupy these seats are the ends of the axle rod 35a of the reserve roll, the rod 35a being disposed in the web of the reserve roll in the same manner as is the rod 35 in the active roll. The web 48 is drawn outwardly and downwardly from the body of the roll 46 and passed into engagement with the rear of a guide roll Si) and in front of a pair of short length guide rolls 511 mounted at the rear of the longer single front roll 50. The rolls 51, as shown in Fig. 3, are rotatably mounted on the forward parallel portions of looped axle rods 52, these rods having their opposite ends secured in mounting plates 53 stationarily positioned on the inner faces of the side panels 22 in a plane above the active roll 33. The ends of the axle 54 of the guide roll 50 are supported for rotation in slots 55 formed in the plates 53. Coil springs 56 are united with the ends of the axle 50 and on the side panels 22 and serve to maintain the rolls 50 and 51 in firm contact with the web 48 of the reserve roll 46 as said web is advanced toward the bearing seats 32. The short, longitudinally spaced guide rolls 51 facilitate the positioning of the web 48 of the reserve roll between the guides 50 and 51.

The leading edge 47 of the web 48 is formed with a selvage hem 57 for the reception of a removable longitudinally extending connecting rod 58. The outer ends of this rod carry, as does the rod 35, spaced collars 59. Positioned on the ends of the rods 58 and disposed between the collars thereon are the fully turned eye-forming terminals 60 of a pair of readily deformable metal connecting links or hooks 61, the lower ends of these links, when the same are first mounted on the ends of the rod 58, being formed with partially closed eye-forming eX- tensions 62, which possess the open configuration disclosed in Fig. 6.

When the reserve roll is rst mounted within the cabinet following placement of the active roll 33, and rests on the seats 49, the web 48 thereof is trained between the guide rolls 50 and 51. The connecting rod 58, carried by the leading edge of the web, has its ends positioned in the inverted downwardly facing sockets 63 of the bearing seat formations 32, with the connecting links or hooks depending therefrom, as in Fig. 6, the open extensions 62 of the links or hooks 61 being disposed in registry with the forward ends of the arcuate seating anges- 27" of the plates r25. 'B-yf the action off gravity, the axle rod 35 of the active -roll is maintained in seated' engagement with the journal seats 28 yin the closed end of eachf recess 26 -until the active roll is about exhausted of its rolled webbing. At this time further downward' pulling on the :loop

I'. causes the axle rod 35 to be unseated and dr-awn forvivardly over the arcuate flanges 27 and into the open lower end's ofthe links or hooks 61, whereby to `unite the trailing end- 37 of the web 34 with the leading edge 47 ofthe web 48.

To secure this unionr of the active and reserve roll webs, the plates or brackets '25, in this instance, are provided 'with depending ears 64` to which are pivoted movable anvil bars 65'. Each of thesebars` is formed to provide an outer end having an inclined or beveled surface 66 which, at its lower end', terminates in a forming socket rlihe inner end of each bar 65 is connected with one end of a coilV spring 68, the opposite end of each of these springs being anchored onan associated panel 22;

When the web 34 is pulled to draw the axle rod 35 thereof forwardly into the full line position thereof shown in Fig. 6, the rod will have its ends deposited in the open lower ends of the links or hooks 61. To bend the extensions 62 of these. links or hooks to form closed `eyes 62u, shown in Fig. 11 and thus securely unite the two roll webs for sustained movement, it is merely necessary to continue downward pulling movement on the web 34 to move the axle rod from the full line position of Fig. 6 to that of Fig. 7. During this movement, the ends of the rod 35 are maintained` between the vertical inner surfaces ofthe stationary anvil flanges 31 and the socketed A outer ends 67 of the movable anvil bars 65. As the web 34 moves downwardly, the bars 65 move with it and the wall formation of the sockets 67 in the outer ends of the bars is such as to cause the latter to ex and bend the extensions 62 from their original open positions, in which the e extensions rest on the beveled surfaces 66 of the anvil bars, to the closed eye-forming positions 4of Fig. 7, wherein the hooks or connecting links -are nally united with the rods 58, as in Figs. l0 and 11.

It will be evident from the foregoing that the present invention provides in a towel-dispensing appliance a means for supporting a plurality of towel rolls with one of the rolls in an active position of towel withdrawal and the other roll in an inactive or reserve position. A web of toweling is adapted to be withdrawn from the active roll in a manner common to wall-mounted towel appliances of this character. When the full length of the web, from which the original active roll was formed, has been about fully withdrawn-from the cabinet of the appliance, the removable -axle rod 35 is moved into coupling engagement with the depending links or hooks 61 provided on the leading edge of the web ofthe reserve roll, the coupling thus made serving without interruption in the use of the appliance, to join automatically the two roll webs, so that the combined lengths of the webs will be available for use by patrons of the appliance. The rods 35 and 58 are removably carried by the ends of each of the rolls. When the webs comprising such rolls are gathered for laundering and re-rolling purposes, the rods are removed from the web hems in which they are positioned and reinserted when clean, laundered rolls are inserted in the cabinet of the appliance. Thus, the metal rods do not interfere with laundering operations, nor do they interfere with the rotation of the yieldable gear devices employed in advancing the webs and in maintaining the web loops L. The hooks or links 61 are disposed beyond the ends of the gear-like web-feeding rolls and, therefore, cannot obstruct or interfere with their operation. The clips, hooks or links 61 are formed from a readily bent ductile metal and, therefore, the closing of the eyes 62a can be performed by normal hand-applied pulling forces on the loop lengths 20.

The construction enables the appliance to be conveniently loaded with the toweling rolls. At the end of a days use, for example, if l an attendant should find that the reserve roll has not been fully utilized, the machine may be readily reserviced for a succeeding days use by transferring the partially utilized reserve roll from `its original lposition on the seats 49 tothe seats 28 of the active roll. When this is done a newroll of toweling is seated in the vacated reserve rollposition and its web and connecting rod 58 tra-ined into engagement with seats 63. These operations are simple and convenient to Vexecute and the arrangement providesa towel-dispensing appliance having areserve capacity capable of meeting demands of the patrons thereof. While a single reserve roll has been shown it will be understood that the apparatus may be extended to receive any desired number of such reserve rolls.
