Wis., a corporation of Wisconsin application october` 1, 1934, serial No. uazs `4 claims. (ci. 31e-se) The dispenser of the present invention is designed particularly for use in the dispensing of interleaved folded waxed sheets which by reason of their smooth surface must be rmly and evenly retained in stacked formation -during the disis from the base of the lim teract any tendency pensing operations, since they -do not tend to frictionally adhere to one another, but develop a tendency to slip/or slide, which must be overcome in order to prevent displacementn The mechanism of the present invention therefore makes provision for the connement and retention of thestacked sheets during all stages inthe dispensing operation, and also makes provision for progressively increasing the distance stack to the point of application for the feeding pressure concurrently with the depletion ci the stack, so that as ih e staclr is depleted the feeding pressure will be applied at the proper point to most advantageously countoward displacement ci the sheets until the last sheet has. been withdrawn. Further objects and details of the invention will appear from. the. description-themed in conjur1c tion with the accompanying drawings, whereinf-w Figure l is a perspective View ci a dispenser embodying the features oi the present invention;

Fig. 5 is a sectional view on reduced scale taken on line 5 of Fig. z The embodiment illustrated comprises a metal .box or cabinet lll having a cover il hinged to the upper edge of the rear wall l2 by means of a pintle it.. The pintle is located inside 'of the rear upper corner of the cabinet so that the rear wall 4o I2 will present an even or uninterrupted surface for attachment to a wall or'the like, or for close contact with a wall in cases where the cabinet is supported upon a table or counter adjacent to the wall or other vertical surface.

. 4d The cabinet further comprises end walls ld and lli, a base or bottom wall lli, and a front panel il. As shown, the bottom wall is formed integrally with the rear wall l2, and the end. walls l and lo are formed integrally with the 6o front panel, although variations in the construc1 tion oi the cabinet are contemplated.

The front panel ll is provided in its center with a longitudinally extending narrow slot it, which at each end merges into a notch i9 in the proxi= as mate end wall ior the purpose of permitting the insertion of a knife or other bladelike member behind the free flap of the outermost folded sheet for the purpose of initially withdrawing the same through the dispensing slot I8.

Inside of the front panel are located upper and lower bearing plates outer edge is' ing flange 2 l 2o, each of which at its provided with a forwardly extend- The bearing plates extend obliquely forwardly toward the dispensing slot, and the inner edges of the respective plates are rearwardly bent to each afford a member 2i, the inner V-shaped bearing edge 23 of which is reversely turned to afford a lip 2i, which arrangement provides a flaredor throated outlet con verging toward the dispensing slot lli.. This arrangement also affords a general convergence tcward the slot which has the eect of bowing forwardly the foremost sheets toward the slot and loosening and separating them from the main body of the stack in preparation for withdrawal, while the configuration oi the bearing plates Zll'is such as center region the ridges of duces surface combines with the to aiord contactwith the of the foremost sheet only along the bearing members 22 which re-= friction to a minimum and which loosening oi'v the foremost sheets incident to their bowing forward to per mit easy withdrawal the slot.

of the foremost sheet from provided with inner which stand in spaced relation to one another, and each of said members has ford a flange its inner edge downturned to ai 2t provided lwith a longitudinally il, which slots are adapted ends of a pintle 2&3 carried by tongues 2li depending from a follower plate it., the center portion of which is bent forwardly to afford a foot 3i, which underlies the rearmost ofthe stack of interfolded sheets S and serves to prevent any oi the sheets from becoming dislodged and slipping under the lower edge of the follower plate. The foot 3l lies ush with the surfaces o the platform members 25, so that the lower edges of 4stack are evenly supported across the base of the stach.

the folded sheets comprising the The upper edge 32 of the follower plate 3d is rearwardly fiared Lto assist in the introduction of a. stackl of sheets, and the vided on its rear face follower plate is proequidistantly from its vertical center with vertically extending flanges 3i a pintle plate 36, the

slots 38 for the reception of rear end of which is pivoted on a its? rear wall of the cabinet near the upper edgel thereof.

The length of the link plate in relation to the follower plate is such that when the follower plate is completely retracted the pintle on the link plate will engage the slots 34 near the lower ends thereof and thus apply feeding pressure near the base of the follower plate, which-point of application is desirable at this stage in overcoming.

the friction or the base of the entire stack 'of sheets which must be continuously fed forward as the withdrawal of successive sheets continues.

i-Hovvever-,v asthe stack becomes vely re` duced and depleted, the forward advancement of thefollower plate will progressively lift the point Iof application for the feeding pressure, so that ultimately the feeding pressure will be exerted above the center of the follower plate, This progressive variation in the point of application of the pressure, commensurate with the reduction in the thickness of the stack, serves to hold the follower plate in substantially vertical relation during all stages of the feeding operation, so that the feeding will progress uniformly irrespective of the dimensions of the stack.

It will be understood that the stack S consis of folded and interleaved sheets of waxed paper whose free forward edges are alternately prel sented upwardly and downwardly in conformity with well understood practice, and as the outermost sheet is withdrawn there will be a tendency i to displace the adjacent'sheets either upwardly or downwardly, as the case' may be, which tendency toward downward displacement is prevented by the contact of the base of the stack with the platform members 25, while alike tendency towardupward displacement is prevented by inwardly extending fingers 43 which are located in position to overlie the outermost folded 'sheets whichare subject to this displacing tendency.

In order to permit inspection of the interior of the cabinet, the side walls thereof are provided with slots 44 extending toward the forward edges The above described arrangement of the follower plate andassociated parts is peculiarly fitted to the feeding of stacked sheets of waxed pivoted on a pintle 41 at the lower rear corner of the cabinet and urged forwardly by a coil spring 48. Ihe follower plate operates in conjunction with a backing plate 49 which is provided with a forwardly extending foot 50 which underlies and supports the rearmost sheets in the stack. 'I'he upper edge 5| of the backing plate is bent forwardly to bear against the upper margin of the follower plate, and the side edges of the backing plate are provided with rearwardly turned flanges 52 for purposes of reinforcement.

The center of the follower plate is provided with a cut-out or recess 53, the side edges being provided with flanges 54, which arrangement af- ,fords clearance for theswingingmovements of the link plate 4Q which rides upon av bead 5l formed across the base of the recess 53. In this -lnstance,

sheets of the stack are supported and fed forward by the conjoint action of the follower plate and backing plate.

The follower plate is freely mounted upon the free end of. the link plate 46 but is held against rearward deectionby contact of the upper edge 5| of thebacking plate, which plate will be held substantially vertical by the engagement of the foot 50 with the base of the stack. 'I'his modication, althoughit does not' possess all of the. ad-

vantages of the mechanism first described, may, nevertheless, be used vwith satisfactory results .under ordinary circumstances.

Although the invention is primarily designed to meet the special requirements involved in the f even and uniform feeding of waxed paper wrapping sheets in interleaved relation to one another in a stack, nevertheless, the mechanism is well adapted to the feeding of sheets of ordinary unwaxed paper, which may be used either as wrappers or as napkins, towels, toilet sheets or the like.
