ROLL DISPENSING DEVICE Filed April 12, 1928 INVE TOR 4; 4% Max ATTORNEY Patented Jan. 28, 1930 EDWARD B. GALLAHER, OF NORWALK, CONNECTIGUT ROLL-DISPENSING DEVICE Application filed April 12,

The present invention relates to improve ments in a dispensing device for paper, or like sheet material, in rolls.

The main object of the invention is to provide a container, within which is rotatably mounted a roll of sheet material, such as for instance sandpaper, including means for holding the free end portion of the roll continuously in condition to be easily grasped by 0 the fingers, for severing the desired length of sheet material. from the coil or web, and folr1 preventing premature unrolling of the Another object of the invention is to produce a device of the character mentioned which is simple in construction, efficient in operation, durable in use and capable of manufacture on a commercial scale, or in other words one which is not so diflicult to produce as to be beyond the reasonable cost of such a contrivance.

A further object of the invention is to so construct the cutting mechanism that it serves at the same time as a clamping device for the free, outer end portion of the web.

With these and otherobjects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described,

pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construct-ion within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a top plan view of a roll container provided with the improved mechanism; and Fig. 2 is a section taken on line 2-2 of Fig. 1.

In the drawings, the numeral 10 indicates a container of any suitable size and configuration. The container may be made of any material, best suited for the purpose. Into this 5 container is placed a roll 11 of sheet material,

On the said top, and

This base plate is mounted uponthe outer faceof the top 14 and tratedin the drawings, vided with a plurality are extended through against the underface base plate risetwolugs 20, one at gitudinal edge of said base plate,

each lon- The roll of sheet material is positioned in the container and its free end portion led through the registering discharge opening 15 and slot 18 and above the base plate, after the clamping and cutting mechanism has been previously shifted in the direction of the arrow shown in Fig. 2 of the drawings around the pins 21. When the said clamping and cutting means is brought into the position shown in Fig. 2 of the drawings, the cutting edge of the mechanism bears against the sheet material, clamping the free end portion of the roll against the base plate. The portion 26 of the mechanism constitutes a handle, by means of which the cutting and clan'iping mechanism may be engaged with and disengaged from the free end portion of the roll. Then the handle is shifted around the pins 21 downwards, the cutting edge of the mechanism is engaged with the roll end, the latter being disposed between the base plate and the said mechanism. As this element is moved in the direction indicated, the cam face 27, in co-operation with the base plate of the device, locks the mechanism in the position shown in Fig. 2 of the drawings, and thereby causes the cutting edge of the device to clamp the roll end against said base plate. Accidental unwinding of the roll is thus effectively prevented.

In operation, the free end portion of the roll extends beyond the cutting edge of the combined cutting and clamping mechanism, as clearly shown in Fig. 2 of the drawings. The sheet material may thus be conveniently grasped by the fingers of the user when it is intended to dispense the required length of sheet material from the container. When it is desired to obtain a piece of sheet material from the roll. the operator first grasps the .end portion of the roll with one hand, lifting with the other hand the handle 26 so as to disengage the cutting and clamping mechanism from the sheet material. The required length of sheet material is then drawn out from the container and then the handle 26 forced down, whereby the sheet material is again clamped against the base plate so as to prevent further retraction of the sheet material and also any loose coils forming within the container. The material which has been withdrawn can then be easily grasped and severed on the cutting edge above described.

The device is very simple in construction and advantageous in use. It may be employed in connection with dispensing of all sheet materials of any suitable widths and thicknesses, the cam face 27, which is disposed below the surface of the body portion of the cutting blade, taking care of varying thicknesses'of the sheet material WVhat I claim is 1. A roll dispensing device comprising a container having a discharge opening and adapted to hold a roll of sheet material, a base plate mounted on said container provided with a slot in alignment with said discharge opening, a cutting blade pivotally mounted on said base plate, the free end portion of said roll being adapted to be extended between said blade and said base plate, and means associated with said cutting blade for causing the cutting edge of the latter to clamp, at will, the free end portion of the roll to said base plate.

2. A roll dispensing device comprising a container having a discharge opening and adapted to hold a roll of sheet material, a base plate mounted on said container provided with a slot in alignment with said dis charge opening, a cutting blade pivotally mounted on said base plate on one side of said slot, the cutting edge of said blade being disposed on the other side of said slot, the free end portion of said roll being adapted to be ettended between the said blade and said base plate, and means associated with said cutting blade for causing the cutting edge of the latter to clamp, at will, the free end portion of the roll to said base plate.

3. A roll dispensing device comprising a container having a discharge opening and adapted to hold a roll of sheet material, a base plate mounted on said container provided with a slot in alignment with said discharge opening, a pair of lugs on said base plate on one side of said slot. a cutting blade pivotally mounted on said lugs, the cutting edge of said base plate being located on the other side of said slot, the free end portion of said roll being adapted to be extended between said blade and said base plate. said blade being provided with a cam surface adjacent its pivot, and a handle portion on said cutting blade for engaging and disengaging, at will, said cam surface with and from said base plate, said cam surface, in co-operation with said base plate, forming means whereby said cutting blade is adapted to act as a means for clamping the free end portion of the roll to said base plate.
