Williams, 11782 Bonnie Brae Drive SW., Massillon, Ohio Filed .luly 24, 1962, Ser. No. 212,091 2 Claims. (Cl. era-ea The present invention relates to new and useful improvements in material dispensing apparatus and more particularly to a motor driven dispenser for sheet material in roll form such as toilet tissue, paper towels, or the like.

The present application is a continuation-in-part of application Serial Number 195,465, filed May 17, 1962 entitled Sheet Material Dispenser.

7 United States Patent U In the past, mechanical dispensers, mostly hand operated, have been suggested for unr-olling and dispensing of sheet or web material such as paper towels, waxed paper, tape, tickets, and the like. These devices were generally cumbersome and expensive to build and did not generally present a neat unobstrusive appearance when installed.

It is an object of the present invention to provide a sheet material dispenser that is operated by an electric motor actuated by an accessible hand switch or button.

Another important object of the present invention is to provide an electric tissue dispenser which may be housed entirely within a room wall and which presents a trim neat appearance.

A further object of the invention is to provide a toilet tissue dispenser driven by an electric motor which may be easily swung out from a wall for refilling the paper supply or maintenance of the motor or drive mechanism.

A still further object of the invention is the provision of a motor-driven feed belt assembly for a sheet material dispenser which resiliently engages material being fed and which will not tear or crinkle even delicate material such as toilet tissue.

Another object of the instant invention is the provision of a motor-driven feed belt assembly for a dispenser for perforated sheet material which will permit manual pulling of the material end without tearing intermediate two perforation lines.

A further object of the invention is to provide a motordriven feed belt assembly for a sheet material dispenser which will insure that manual pulling of the free end of the material will cause tearing thereof within the housing of said dispenser.

It is another object of the invention to provide a chute structure for a motor-driven sheet material dispenser which serves to guide the material from its roll to the discharge opening of the dispenser without folding or fouling in the machine.

Other objects of the invention are to provide a motoroperated sheet material dispenser bearing the above objects in mind which is of relatively simple construction, has a minimum number of parts, is inexpensive to manufcture, and is at all times eflicient, reliable, and safe in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying drawing in which:

FIGURE 1 is a perspective view of the new dispenser of the present invention installed in a tiled bathroom wall;

FIGURE 2 is a side elevational view of the dispenser ICC taken along the line 22- of FIGURE 1 and showing the folding of the front cover plate in dotted lines;

FIGURE 3 is a cross-section taken along the line 33 of FIGURE 2 with the roll of paper removed; and

FIGURE 4 is a fragmentary cross-section along the lines 33 of FIGURE 3.

Reference is now made more specifically to the drawings wherein like numerals designate similar parts throughout the several views and wherein the dispensing device con stituting the subject matter of this invention is designated generally at it) and is shown flush mounted in the usual tiled bathroom wall 11.

The dispenser body is preferably fabricated in the form of a sheet metal box or housing 12 being open at the front and having a cut-away portion at the bottom adjacent the open side. Of course, plastic or wood or other suitable material could be used for thehousing if so desired. A mounting flange 13 is welded or otherwise secured around the four sides of the box to permit neat mounting in a wall recess regardless of the accuracy of the wall cut. A front sheet metal cover 14 is hingedly attached to the box in a manner more specifically described in the aforementioned copending application, Serial Number 195,465. By the use of this construction, the entire front cover can be pivoted outwardly and downwardly to the dotted line position of FIGURE 2 to expose all of the operating components for repair and to permit easy reloading of the machine with a new sheet material supply.

In order to permit ease of maintenance and of refilling, all of the mechanical elements of the feed mechanism, including the motor, are attached to the inside of the front cover 14 so as to be accessible upon opening of the cover. The rolled tissue paper or the like, shown at 15, is also received within the front cover section.

Fixed to the inside of the cover 14 as by flanges 16 are two spaced parallel side plates 17 and 18 and a bottom plate 19 which spans and closes off the bottom between the two plates. three elements, all of the mechanical components are supported. Formed in each of the side plates 17 and 18 are openings for reception and journalling of the ends of belt roll shafts 2t), 21, and 22. A slightly larger hole 23 is also provided in each of plates 17 and 18 for the loose reception of the end of belt roll shaft 24. Further holes are provided in the side plates for reception of motor mounting screws 25 and tension springs, later to be described.

In order to maintain the rigidity and spacing of the side plates 17 and 18,

spacer members

28 and 29 are provided adjacent the upper side of the plates and spanning them. Spacer member 28 is preferably of sheet metal and also serves the secondary purpose of acting as a front support plate for the rolled material 15 and prevents it from slipping down into the mechanical moving elements when the roll diameter decreases in size. If desired, yet a further rigidifying sheet metal cross member 30 may be provided at the back of the side plates adjacent the top.

Guide chute 31 receives the sheet material and guides it downwardly to the discharge opening 32 formed in the overhang of the front cover 14. The chute has a general box-like construction of sheet metal or plastic and includes the top plate 33 and the :bottom plate 34. If desired, separate side plates may also be used, but the top and bottom plates may be attached directly to the side plates 17 and 18 utilizing them as side members to Within the enclosure defined by these sheet material to be dispensed.

enclose the chute. lf separate side plates are used, they may flare outwardly adjacent the discharge end. As can be seen from FIGURE 4,1the top plate 33 is of greater length than the bottom plate. The entire chute is mounted angularly as shown in FIG. 4 and extends bet-ween the side plates 17 and 18 and is attached thereto as by welding or thelike. The width of the chute between the two side plates is slightly greater than the width of the Ithas been found that toilet tissue is-"generally standardized in width at 4 /2' inches. If the device is to be adapted to dispense such tissue, a preferable" width for the chute interior would be 4% inches. Each of the top' and bottom plates of the chute is provided with roll receiving recesses forthe belt rolls generally rectangular in sh ape as shown-at" 35.

The rearward recesses for the top and botto'mbelt'rolls are at the very edges of the top and bottom chute plates and hence are, open atthe rear. This facilitatesin'itial v feeding of the material. v I

Wooden belt rolls 36, :37, 38, and 39 are fitted securely on the

belt roll shafts

The shafts are so positioned;that-the-roll peripheries willextend through the roll receiving recesses 35 in the chute 31. Whilethe rolls are preferably made of -wood,1'hard rubber, plastic and cork are equally effective. The shafts 7 are held from axial displacement by positioning washers or Circlips 40 which may-be fitted in annular recesses formed in the shafts.

The belt rolls 36 and 39 are of a gre'aterlength; than the

rolls
