ELVY W. BEELER, OF DUR-ANGQ, CDLORADO.

PAPER TRIMMER.

Application filed September 19, 1921.

To all whom it may concern.

Be it known thatl, Envy W. Barman, a citizen of the United States, residing at Durango, in the county of La Plata and titate of Colorado have invented certain new and useful Improvements in Paper 'lriinmers, of which the following is a specitication, reference being had to the accornpanying drawings.

This invention relates to tools particu larly adapted for use by paper-hangers, and has for its object the provision of a novel paper trimmer or cutter designed primarily for cutting off the margins of wall paper.

An important, and more specific object is the provision of a paper trimmer and cutter designed to be used in conjunction with a straight edge used as a guide, the device including a guide roller of relatively small diameter intended to be drawn along the straight edge and further including a relatively large cutting disk engageable with the paper to be out the purpose of the differences between the relative sizes of the roller and disk being to cause faster travel of the cutting edge of the disk for insuring smooth cutting or trin'nning action.

Another object is the provision of a device of this character which is provided with a handle which is off center so that the device 'may be reversed so as to be readily capable of use by either a right or left handed op erator.

Still another object is the provision of a rotary cutter of this character which is provided with a novel mounting for the roller whereby the roller and cutter disk may be removed bodily from the supporting frame with a minimum amount of trouble.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture highly eflicient and rapid in use, durable in service and a general improvement in the art.

lVith' the above and other objects and advantages in view. the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which:

Figure l is my device;

Figure 2 is a plan view;

Figure 3 is a fragmentary elevation of the opposite side; and

an elevation of one side of Serial No. 501,619.

Figure at is a cross sectional view taken through the axle of the roller. 1

Referring more particularly to the drawings, I have shown my device as comprising a U-shaped frame it) which is formed on its bight portion or back with a socket 11 located nearer to one side of the frame than the other. Engaged within this socket is the reduced end 12 of a handle 13 ofsuitable length held in place by a rod 14 passing centrally through the'handle and having a threaded end 15 screwed into the frame. 10. By this connection it will be seen that the handle may be readily removed and replaced in case it should becon e split or be otherwise rendered unserviceable. The end portion ofone arm of the frame is formed with acircular hole 16. while the end of the other arm is formed with a key hole opening or slot 17.

Extending transversely of the frame is an axle bolt 18 which has its headed end 19 formed with a lug and which has its thor end threaded and carrying a nut 20. The lug is of such size and shape as to pass through the lateral portion of the key hole slot 17 so that when the axle bolt is inserted. in place, rotation will be prevented by the lug while longitudinal movement is prevented by virtue of the engagement of the head 19 upon the edge of the circularportion of the key hole slot 17.

The above described axle bolt serves as a bearing for the roller 2-1 which is provided internally with a rigidly secured bearing sleeve 22- rotating upon the aXle bolt 18. Disposed against one end of this roller 21 and secured thereto, as by means of ordinary wood screws 23, is a disk 24 having a beveled cutting edge 25. This disk is naturally formed at its center with a suitable hole for the passage of the bolt 18.

In use the device is associated with a suitable table which has its edge provided with the usual straight edge, this table being well known and being of the type commonly employed by paper hangers. lhe paper to be trinnncd or cut is of course laid upon the paper-hangei"s table in the usual manner with the undesired margins extending beyond the edge. The operator then grasps the handle of my device and so disposes the tool that the roller 21 will roll upon that portion of the paper overlying the straight edge, with the cutting blade 24: engaging against the outer edge of the straight edge. The

device is then pushed along whereupon rotary movement will be imparted to the roller and the disk and the beveled edge of the disk ill cooperate with the beveled edge of the straight edge for effecting an ellieient shearing action Which will cut the paper. Owing to the fact that the disk 2 1- is of much Pi'eater diameter than the roller 521, it Will he apparent that the speed of travel of a point on the periphery of the dish will be much greater than the speed of travel oi a point on the periphery of the roller and this will cause a much smoother and more rapid cut ting action than would occur it these two elements were 0t substantially the same diameter.

From the foregoing description and a study of the drawings it will he apparent that I have thus provided a simply constructed tool which is Well adapted for the use of paper-hzmgers and in "fact every one having occasion to cut or trim Wall paper or other similar material in a very eliicient manner.

It is to be not-ed that in case oi necessity the roller and dish assenibly may he removed and that the disk ma be easily subsequently removed tron'i its supporting roller in case of any necessity tor replacement or the like. It is also to he noted that owing to the fact that the handle structure is located nearer to one side of the supporting frame than the other, the device may be easily used by either a right or left handed operator merely by turning it over, it being desirable that the handle be located closer to the cutting disk than to the opposite side of the tool. This feature of the construction is important in that it eliminates, in a great measure, the strain applied to the hand during the cutting operation with the usual construction, in which the cutting disk has a tendency to elevate at all times because of the leverage it has upon the handle. With the present construction this leverage is removed and the p ire of the handle to hold the roller in contact with the tab e is applied practically 'rectly to the cutting disk. The etliciency oi the tool is further assisted by providing a heavy roller such as hereinhe't'ore referred to,

lVhile l have shown and described the preferred embodiment of the invention, it is 01" course to be readily understood that I reserve the right to i'ualre such changes in the form, construction and arrangementof parts as Will not depart from the spirit 'ofthe invention or the scope of the sub-joined claim.

Having thus described my invention, I claim:

i tool of the character described compm i a U-shaped supporting frame formed at llS o ht portion to one side of the center thereof vith a. socket, a handle detachahly engaged -\vithin sa'd socket, a pivot bolt de tachably engaged with and extending transversely across the open end of said frame, a heavy metal roller journaled upon said pivot belt, a relatively large cutting disk secured to that end of said roller most nearly in alignment with the axis of said handle.

In testin'iony whereof I hereunto a'tlix my signature.

ELVY XV. BEELER.
