3 Claims. (Cl. 312-39) My present invention relates to dispensers for rolled sheet material and particularly to dispensers for cotton in sheet form.
Heretofore there have been many rolled sheet dispensers, but usually such dispensers are made with spring activated feed rollers and numerous parts which are permanent parts of the dispenser case. Such constructions are likely to get out of order and require too much labor and time to manufacture, so that the initial expense of the dispenser is higher than most people will pay. Also, such prior art dispensers when they become out of order, such as the spring or the feed mechanism becoming broken are then usually worthless and. not repairable by the average user.
One object of my invention is to eliminate spring activated feed rollers and other feed arrangements, such as usually get out of order and cannot be repaired.
Another object of my invention is to provide a compact and economical wall mounted dispenser comprising a unitary casing open at the top and having a plurality of detachable independently manufactured parts for quick assembly as a part of the casing to form the completed dispenser or for ready interchanging.
With the above and other objects in view the device consists of the parts, arrangement, and
combinations thereof described in the following description and illustrated in the accompanying drawings, wherein:
Fig. 1 is an isometric view of my invention mounted on a wall or the like ready for use as a dispenser.
Fig. 2 is a transverse cross section view taken on the section line 2-2 of Fig. 1.
Fig. 3 is a longitudinal cross section view taken on the section line 33 of Fig. 3.
Fig. 4 is a perspective view of a roll holder or tray such as is detach-ably mounted in the dispenser casing shown in the preceding figure.
Referring in detail to the drawings by reference characters for the several parts of my invention and first with special reference to Figs. 1 and 2, there is illustrated a rectangular box or casing l0 formed with a bottom wall II, front and rear walls I2 and I3 and end walls I4 and I5. The top of the box I0 is open, but it is closable by a closure l6 pivoted to the top edge of the rear wall 13 by a multipintle hinge IT. The closure [6 is formed with a depending skirt I8, which overlaps the top edge surface of the box walls. Also to hold the closure in closed position the same is provided with a yieldably resilient latching tongue l9, which frictionally engages the side of the front wall l2.
The front wall I2 is formed with an elongated longitudinal guide slot 20 for a, shaft 2| carrying a cutter blade or knife 22. This shaft is threaded into a threaded socket in the body of the knife, which shaft is slidable with the knife along the slot within the box 10. The shaft 2| extends through this slot and supports a handle 23. Vertical movement to compensate for the thickness of the sheet to be cut is provided by vertical slot 24. Slot 20 is superimposed above a dispenser slot 25 in the wall [2. The lower edge of the wall I2 at slot 25 is bent over from the slot opening 25 to form a lip or rest surface 28 with a curved down edge extending exteriorly of the wall. Rearward. of the slot 25 and extending interiorly of wall I2 is an elongated anvil surface 21, see Fig. 2, with a knife edge receiving groove 28 along and within which the cutting edge travels for the purpose of transversely cutting a section of material, such as sheet cotton 29 from the roll of cotton 30 or the like after it has been pulled from the box through dispensing slot 25.
The dispensing mechanism within the box H1 comprises a plurality of interchangeable parts, the box having each end wall l4 and I5 formed with a pair of superimposed oppositely aligned openings to receive the shaft ends of the feed rollers 31 and 32 spaced rearwardly on each side of the edge of the anvil plate 21.
The roller 32 is a drive roller and may be made slightly oval in cross section to facilitate the dispensing action of the rollers on the web of the strip as it is thus unwound from the roll 30. The power to the roller 32 may be supplied by a. handle or crank 34, which has a socket adapted to thread into the extended end of the shaft end of roller 32. The web pays out from the top of the roll 30, which is supported in a roll conforming yieldably resilient trough 33, under an idler guide roller 35. The roller 35 has extended shaft ends extending through oppositely aligned openings in the box end walls l4 and 15, respectively.
The end wall [5 of box In is formed from the top rim thereof with a slot 36, see Fig. 2. The slot 36 terminates a short distance from the top rim int-o a curved bearing surface upon which rests the stud shaft 31 formed from the yieldwhen supported in the box Ill each ear presses into frictional contact with the adjacent inner surface of its respective side wall, namely 14 and I5. Thus the ears serve as friction brake means to hold the trough in position. The side wall [4 is formed with an opening oppositely aligned with respect to the curved bearing surface at the terminal end of slot 36 to receive the stub shaft 40, thereby completing the support of the trough 33. The trough is formed along its forward longitudinal edge with a yieldable resilient curved tongue 4|, see Fig. 4, and along its rear longitudinal edge with a downwardly curved bead 42, thereby forming a smooth convex surface over which travels the web of strip cotton or the like as it is pulled forward by the dispense ing rollers 3| and 32.
The roll of strip cotton to be dispensed is clamped or gripped by the resilient tongue 4 I, as this tongue due to the inherent resiliency of the trough material is formed to yieldably bias upward toward the rear wall of the trough 33. Thus when rolls of various sizes are in the trough the tongue 4! serves to hold them in position, so that even though the pull on the web 29 should become excessive and cause the trough to rock or rotate in the direction of pull, the roll will not drop from the trough. Normally the friction brake, that is, the ears 38 and 39 will hold the trough fixed.
The fact that the trough is rotatable upon excessive pull caused by unexpected binding or jamming at the dispensing slot 25 is a very beneficial feature, as with this rotatable floating arrangement the trough will automatically release any such binding or jamming.
The rear wall of the box 19 is formed with keyhole slots 43 and M to provide for mounting the device upon a wall or other vertical surface and when it is desired to load the device it may be detached from the wall, if desired.
Operation The use of the device is probably apparent from the foregoing description. However, assuming the device is mounted on wall, briefiythe steps of operation are to first raise the box cover ii) to load the dispenser by positioning the novel trough 33' with a roll to be dispensed therefrom gripped therein by trough M in its friction braked supported position between end walls l4 and I5, next the web of material is manually unrolled from the top of the roll over the convex rounded surface of bead t2 and turned around the underside of guide roll and into the bight of the dispenser rollers 3| and 32, through the slot 25 trough being formed. at each end with outwardly During each dispensing movement of the web 29 by the feed rollers, the trough 33 will normally be held against forward rocking by the frictional resistance between the brake cars 38 and 39 and their respective side walls, but if the feed should jam ahead of the rollers 3! and 32 the trough will turn, thereby relieving any excessive tension on the web and thus permit the web to feed forward easily until the jammed condition is corrected.
