3 Claims. (Cl. 164-45) The invention relates to a device for cutting rolls of sheet material, and is especially adapted for the cutting of rolls of roofing felt and the like.

In the construction of roof coverings of sheet material such as roofing felt, it is usually necessary that at least one strip of the roofing material be cut lengthwise to produce a narrower strip to finish the roof covering at one side of the roof.

The width of the strip to be cut varies, depending upon the dimensions of the roof to be covered. Such roofing felt is obtained in rolls, and in order to cut a strip of the desired width it is common practice to unroll the same and cut it longitudinally with shears or the like. As this work is done on the roof it is frequently very difficult to handle a long strip of roofing felt to cut the same, particularly on a windy day.

The object of the invention is to provide means for quickly and easily cutting a strip of roofing felt "or the like to any desired width, while in its original rolled condition.

A further object is to provide a simple, inexpensive and easily operated device for cutting a roll of roofing felt or the like.

A still further object is to provide such a device in which a roll of roofing felt or the like may be held in proper position and cut at the desired point.

Another object is to provide a device of this character in which the roll of roofing felt is supported upon rollers so that it may be rotated for making successive cuts around the circumference thereof.

Still another object of the invention is to provide a device of this character comprising a base having spaced rollers journalled thereon for supporting a roll of material to be cut, a hinged yoke for clamping the roll of material in position for cutting, and a knife blade adjustably mounted upon a lever handle fulcrumed upon the base.

The above objects together with others which will be apparent from the drawings and following description, or which may be later referred to, may be attained by constructing the improved cutter in the manner hereinafter described in detail and illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of a device embodying the invention, showing a roll of roofing felt clamped therein with the knife blade in operative position cutting into the roll of roofing felt;

Fig. 2 is a perspective view of the device on a larger scale with the roll of roofing felt removed;

Fig. 3 a top plan view of the device with the hinged yoke, and the lever handle carrying the knife blade, in the raised or initial position;

Fig. 4 an enlarged, fragmentary, sectional view taken as on the line .4-4, Fig. 2, showing the manner of hingedly mounting the yoke;

Fig. 5 an enlarged fragmentary section as at 55, Fig. 2, and

Fig. 6 an enlarged, detached, perspective view of the knife blade and the adjustable collar therefor.

Referring now more particularly to the embodiment of the invention illustrated, in which similar numerals refer to similar parts throughout, the improved roll cutting device is mounted upon a base including the channel member 10, to opposite sides of which shorter inverted channel sections 11 and 12 are shown attached at a point spaced intermediate the center and one end of the channel member 10.

The sections 11 and 12 may be attached to the member 10 by any suitable means, such as welding as indicated at 13. The base thus formed is of generally cruciform shape, as best shown in Figs. 2 and 3.

A spaced pair of parallel rollers 14 are mounted upon the base, above and at opposite sides of the channel member 10. For this purpose, end plates 15 and 16 may be attached to opposite ends of the channel member 10.

These end plates are of considerably greater length than the width of the channel member 10, and each has attached to opposite ends thereof the upwardly converging arms 17.

The rollers 14 are preferably in the form of tubes and for the purpose of journalling them upon the arms 17, a bushing or thimble 18 may be fixed within each end of each roller, as best shown in Fig. 5, and a stud or pintle 19 is fixed to the upper end of each arm 17.

For the purpose of easily and readily removing and replacing the rollers 14, the end plate 16 may be removably connected to the adjacent end of the channel member 10 as by the bolts 20 and nuts 21.

An upright 22, preferably in the form of a channel section, is welded or otherwise rigidly attached to the outer end portion of the base member 12, as indicated at 23, for the purpose of mounting the hinged yoke, indicated generally at 24, and the lever handle 25. This hinged yoke may be formed of a spaced pair of tubular members 26, each having a substantially semi-circular portion 27 terminating in the outwardly inclined straight portion 28.

A cross bar 29 is attached-to the straight portions 28, near the outer ends thereof, for holding the same properly spaced apart. The opposite end of each of the tubular members 26 may be flattened, as shown at 30, and a bar 31 is welded or otherwise attached thereto holding the same in proper spaced position.

This yoke is hingedly mounted upon the upright 22 by means of the pin 32 located through suitable apertures 33 in the flattened end portions 30 of the yoke members and through apertures 34 in the upper portion of the channel member 22. The pin has a head 35 at one end, and a cotter pin or the like, as indicated at 36, may be located through a suitable aperture in the other end of the pin for retaining the same in position.

The lower end of the lever handle 25, which may also be in the form of a tube, is welded or otherwise rigidly attached to the perpendicular tubular member 37 through which the pin 32 is located providing a hinged mounting or fulcrum for the handle lever.

The knife blade 38 may be adjustably mounted upon the handle lever 25. For this purpose the knife blade may be carried by an adjustable collar 39which may be held in adjusted position upon the handle lever by the set screw 40.

A spaced pair of flanges 41 may be welded or otherwise rigidly attached to the collar 39, as indicated at 42, and the inner end of the knife blade 38 is clamped therebetween, as by the clamping screws 43.

For the purpose of holding the yoke 24 in clamping position upon a roll of roofing felt or the like, as indicated at R in Fig. 1, a projection 44 may be provided upon the cross arm 29 of the yoke and adapted to selectively engage one of the apertures 45 in the perforated metal strip 46 which may be hingedly connected to the top of the base member 11 as indicated at 47.

In the operation of the device, when it is desired to cut a roll of roofing felt or similar material, the roll of material is placed in proper position upon the rolls 14. The yoke 24 is then swung down over the roll of material, as indicated in Fig. 1, and the projection 44 thereon is engaged with the proper aperture in the perforated strip 46 to hold the yoke in the closed or clamped position as shown in Fig. 1.

The lever handle 25 is then pulled forwardly, as shown in said figure, plunging the end of the knife blade into the roll of roofing felt at the desired point, as shown in Fig. 1, and as the lever handle continues to descend the knife blade will cut through to the center of the roll making a cut part way around the circumference of the roll of material.

The lever handle is then raised, withdrawing the knife blade from the roll of material, and the perforated strip 46 is released from engagement with the projection 44 of the hinged yoke so that the roll of material may be rotated a partial turn upon the rollers 14 and again clamped in position by means of the yoke so that another cut may be made. This operation may be repeated several times until the cut is completed entirely around the circumference of the roll of roofing felt.

From the above it will be seen that a simple, rugged and easily operated device is provided for quickly cutting a roll of roofing felt or the like at any desired point.

In the foregoing description, certain terms have been used for brevity, clearness and understanding, but no unnecessary limitations are to be implied therefrom beyond the requirements of the prior art, because such words are used for descriptive purposes herein and are intended to be broadly construed.

Moreover, the embodiments of the improved construction illustrated and described herein are by way of example, and the scope of the present invention is not limited to the exact details of construction.

Having now described the invention or discovery, the construction, the operation, and use of preferred embodiments thereof, and the advantageous new and useful results obtained thereby; the new and useful construction, and reasonable mechanical equivalents thereof obvious to those skilled in the art, are set forth in the appended claims.
