PAPER SHEET DISPENSER Filed June 18, 1965 2 Sheets-Sheet 2 ATTORNEYS United States Patent Ofilice 3,291,339 Patented Dec. 13, 1966 3,291,339 PAPER SHEET DISPENSER Lester W. Hein, 1526 E. Alton, Independence, Mo. Filed June 18, 1965, Ser. No. 465,094 4 Claims. (Cl. 221-45) This invention relates to dispensing devices and, more particularly, to apparatus for conveniently dispensing a single sheet from the top of a stack of sheets.

The principal objects of the present invention are: to provide a sheet dispenser which conveniently exposes a large proportion of the top sheet of a stack for grasping; to provide such apparatus wherein there is no objectionable bulge in the center of the stack and which has a large capacity for its size; to provide a sheet dispensing device which permits the top sheet to be easily withdrawn without wrinkling even if lateral force is applied to the sheet as it is withdrawn; to provide such apparatus wherein the sheet to be dispensed is retained only by contact with smooth flange members at the upper and lower edges thereof; to provide such apparatus which may be used in a great variety of positions and is easily loaded merely by urging the sheet stack through the dispensing opening; and to provide such apparatus which is of relatively simple construction, inexpensive to produce and rugged and reliable in use.

Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings wherein are set forth by way of illustration and example of certain embodiments of this invention.

Referring to the drawings in more detail:

The reference numeral 1 general indicates a sheet dispenser embodying this invention. The dispenser 1 comprises a rectangular container 2 having a pair of spaced apart oppositely disposed upwardly extending

end walls

3 and 4 with upper edges 5, lower edges 6 and side edges 7. A pair of spaced apart oppositely disposed upwardly extending

side walls

8 and 9 have upper and lower edges 10 and 11 respectively and side edges 12. The

side walls

8 and 9 .are joined to the

end walls

3 and 4 along the respective side edges 7 and 12 forming four corners 13 on the container 2.

The

side walls

8 and 9 extend horizontally inwardly of the container 2 at the side wall upper edges 10 forming opposed parallel transversely extending strips 14 having inner edges 15 facing each other. The strips 14 partially cover the top 16 of the container 2 and are spaced above the end wall upper edges 5 a small distance, for a reason noted below. A bottom Wall 17 is joined to the side and end walls along the lower edges thereof closing the bottom 18 of the container. The bottom wall 17 has end flanges 19 extending upwardly externally of the container 2 and suitably joined to the

respective end walls

3 and 4, for example, by spot welding. The bottom wall 17 also has side flanges 20 extending upwardly therefrom adjacent the

side walls

8 and 9 on the inner surface 21 thereof, and are secured thereto, in the illustrated example, by sheet metal screws 22.

The

side walls

8 and 9 are respectively divided into three laterally spaced apart

sections

23, 24 and 25 forming

pairs

26 and 27 of respectively opposed vertically and horizontally extending elongated slots. Elongated tubular members 28 are disposed externally of the container 2 and extend adjacent each of the

slots

26 and 27 between the side wall lower edges 11 to the side wall upper edges 10. The tubular members 28 are each comprised of an elongated strip 29 curved longitudinally centrally through less than 360 degrees as best illustrated in FIG. 4. The members 28 have spaced apart oppositely outwardly extending mounting legs 30 and 31 forming a longitudinally extending slot 32 providing access into the tubular member and aligned with the respective

side wall slots

26 and 27. The members 28 are secured to the outside surface of the respective side wall sections 23-24 and 2425 by the legs 30 and 31, for example, by spaced apart spot welds 33, and maintain the side wall sections structurally in fixed relation with respect to each other.

A retainer angle 34 is secured to each of the

side walls

8 and 9 along the lower edges 11 thereof and has one leg 35 horizontally extending directly beneath the respective tubular members 28 blocking the lower open ends thereof. The other leg 36 of the retainer angles 34 extends upwardly adjacent the side flanges 21) on the inside surface 21 of the respective side walls and receives the screws 22 therethrough forming a rigid assembled structure. The horizontally extending leg 35 of the retainer angles 34 has spaced apart fastener receiving bores 37 extending there through for selectively mounting the container on a surface (not shown) in the event that the flush mounting illustrated is not desired.

A flange member 38 extends longitudinally beneath 1 each of the side wall strips 14 presenting a smooth downwardly facing surface 39 for contacting the uppermost sheet 40 of a stack of sheets 41 held in the container 2 for dispensing. The flange members are secured to the strips, for example, by welding at 40. Flange members 38 each have a lip 42 curved upwardly around the respective strip edges 15 so as to present a smooth upwardly curved outer surface blending into the lower surface 39 to aid in dispensing the uppermost sheet 4t) without snagging. The lips 42 are spaced apart a substantial distance across the top 16 of the container 2 defining with the end wall upper edges 5 a dispensing opening 43 which covers the greater portion of the container top area.

The flange members 38, although secured beneath the strips 14, are maintained slightly above the end wall upper edges 5 providing spaces 44 therebetween permitting the uppermost sheet 44) to slide laterally without binding in the event that a lateral force is applied to the sheet during grasping for withdrawal. This reduces the possibility of wrinkling the sheet under such conditions.

A pair of parallel

elongated bars

45 and 46 extend between the

respective side walls

8 and 9 and have opposite ends 47 extending through the

opposed slot pairs

26 and 27 and into the respective tubular members 285 for vertical movement of the bars generally between the bottom wall 17 and the flange members 38. Guide members 48 are located in each of the tubular members 28 beneath and contacting the respective bar ends 47. The guide members 48 are preferably short lengths of cylindrical rod which are slidably received within the tubular members. A vertically extending helical compression spring 48 is contained in each of the tubular members 28. The springs 49 are engaged between the horizontal leg 35 of the respective retainer angle 34 and the guide members 48 for resiliently urging the

bars

45 and 46 upwardly, which, in turn, urge the stack 41 upwardly. As noted above,

the uppermost sheet 40 of the stack is urged into sliding contact with the flange members 38. The

bars

45 and 46 extend transversely of the flange member 38 whereby there is no bulge in the center of the stack at the dispensing opening 43.

Fluish mounting end angles 50 and fiush mounting side angles 51 respectively have a vertical leg 52 secured, for example, by spot welding, to the side and

end walls

3, 4, 8 and 9 adjacent the respective upper edges thereof. The other leg 53 of the respective

flush mountaing angles

50 and 51 extends outwardly normal to the respective side and end wals. The legs 53 have spaced apart fastener receiving bores therethrough receiving, in the illustrated example, screws 54 for mounting the container 2 depending through a planar member 55 with the dispensing openin g 43 relatively flush therewith.

In operation, the container is loaded merely by urging the stack 41 downwardly through the dispensing opening 43 so as to compress the springs 49 until the upper and lower edges of the uppermost sheet 40 are disposed beneath the flanges 38. Upon release, the springs 49, through the

bars

45 and 46, urge the stack upwardly until the uppermost sheet 40 is slidably engaged with the flange members 38. When a sheet is required to be dispensed, the upper surface of the uppermost sheet is grasped by the hand so as to bend transversely which causes one or both of the upper and lower edge portions thereof to withdraw inwardly from beneath the flange members 38. Upon continuing to withdraw the sheet upwardly, both sheet edge portions are released and the entire sheet is withdrawn upwardly from the dispensing opening for use. As noted above, if a lateral force is applied when the sheet is being withdrawn, the sheet is free to slip through the space 44 laterally of the dispensing opening, thus limiting any tendency for the sheet to bind or snag as it is withdrawn.

The described construction permits the use of relatively short container height while handling a large sheet capacity. Further, the construction is relatively simple and may be economically carried out on a production line basis.
