Specification of Letters Patent.

Patented Nov. 9, 1915.

Application filed September 24, 1814. Serial No. 868,292.

To all whom it may concern:

Be it known that I, AARON H. HANDY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Automatic Paper- Cutters, of which the following is a full, clear, and exact description, such as W111 enable others skilled in the art to which it appertains to make and use the same.

The invention relates to paper cutters for cutting lengths of paper from a roll for wrapping packages in stores and the llke.

It is essential that the roll of paper be capable ofbeing conveniently located, that the paper be locked against unrolhng durmg the cutting operation, and that the paper protrude some distance beyond the knife after each piece is cut from the roll so that the end last out from may be easily gripped by the hand and pulled out to the desired length before it is again cut.

The present invention seeks to provide an improved paper cutter and paper roll mounting, preferably inclosed to protect the paper from settling dust, and so arranged that the mountings including the roll and the cutter may be loosely piled one upon the other in any convenient manner, together with locking means to hold the roll from turning while the paper is being cut from the roll, and a mechanism that W111 allow the remain ing end of the paper to protrude beyond the knife after each piece of paper is cut from the roll.

With these and other objects in view, the invention consists in the features of constructions and arrangements of parts hereinafter set forth illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings: Figure 1 is an elevation paper cutter and a roll of paper mounted in an inclosed frame. Fig. 2 1s a view in sectional elevation taken on line ao of Fig. 1. Fig. 3 is an enlarged erspective view of the cutting member. Fig. 4: is an enlarged perspect ve new of paper guide. Fig. 5 is a view in elevation of a modified form of mounting the paper cutter.

The paper cutter is preferably mounted in a frame or casing comprising bottom pieces 1, top pieces 2, front pieces 3 and 4, back '55 P100885 towln'ch ishinged by hinges 6 door 7 and end pieces 8. The

and has the roller 11 fitted therein with suitable bearings at to keep the paper from unrolling too easily, and also as a means of lifting the guide and keeping the paper in contact with-the cutting edge 14 of the cutting member 15. Guides 16 are provided in the casing at either of the ends 8 to receive the shaft 17 upon which the paper 18 is wound in a roll 19.

The cutting member 15 is pivoted at 20 to the casing, the parts being shown at rest in full lines of Fig. 2, while in dotted lines of the same View the guide member 9 and the cutting member 15 are shown in the positlon occupied when the paper 18 is being cut from the roll 19. The cutting member 15 at the end opposite the cutting edge 14 terminates in concaved projections so formed situated on the member as to contact with the paper 18 on the roller 11 when the member is lifted in cutting position and form a brake to prevent the paper fromslipping during the cutting operation. 7

The roll of paper 19 is placed in the frame with the shaft 17 resting in guides 16, and the paper 18 passed over the-roller 11, under the web 13, and over the end 21 of the guide member 9, the cutting member 15 being proportioned with the bulk of weight toward the cutting edge 14: will lie with the cutting edge on the paper at all times. llhen it is desired to remove paper from the roll the projecting end 22 of the paper is gripped by the fingers of the hand and the paper pulled out to the desired length, after which an upward pull is exerted on the paper when the cutting and guide members assume the position shown in dotted lines of Fig. 2 and the cutting edge 14 will cut the paper, allowing the members to again assume the position shown in dotted ines of Fig. 2, and the paper 18 will protrude as shown by reason of the position of

pivots

10 and 20 allowing the cutting member and the guide member each to oscillate eccentric to the other.

In Fig. 5, the cutting member 15 and the guide member 9 are mounted. in the bracket 23 upon the usual paper roll stand 24, the action of the members and the cutting of the paper being the same as that just described. It is obvious that changes may be made in the details as set forth without departiug from the essentials of the invention.

The paper cutter is of chief importance for the serving of wrapping paper in stores and the like but may be employed for serving ofv toilet paper.,

llaving described my invention, what I claim as new and desire to secure by Letters latent, is

In paper cutters the combination of suitable means to support a roll of paper, and a paper cutter attached to said means, said paper cutter comprising an oscillating guide member and an oscillating cutting member, said guide member having a roller mounted thereon and a web under which the paper may be threaded, said cutting member being provided with a brake at one end and a cutting edge at the opposite end.

:2. In paper cutters the combination of means to support a roll of paper in revoluble position, an oscillating guide member attached to said means, a roller on one end of said guide member, a web in said member to slightly resist the unrolling of paper from a roll supported by said means, an oscillating cutting member, said cutting member pivoted adjacent said guide member with the pivot so arranged that the cutting member will follow the paper for a greater distance than will the guide memher as the paper is drawn from the roll, a brake on said cutting member positioned to lock the movement of the paper when the paper is lifted for the purpose of cutting, and a cutting edge on. said cutting member to cut the paper.

3. In paper cutters the combination of a rectangular inclosing frame, a door in said frame to insert a roll of paper, guides in said frame to receive the journals of a roll of paper, a guide member pivoted within said frame, a roller on said guide member, a web in said guide member to retard the withdrawal of paper from a roll mounted in said frame, a cutting member pivoted within said frame and protruding there from, a brake on said cutting member, and

a cutting edge on said cutting member, an opening in said frame through which said cutting member and said guide member swing as paper is drawn therebetween, said cutting member positioned to swing farther from said frame than will the guide member.

In testimony whereof I affix my signature in the presence of two witnesses.
