PAPER Application filed September This invention relates to a paper cutter, and has for an object to provide an improved construction which is adapted to be worn'on a finger and readily manipulated to cut paper supported on a pad or other support.

Another object of the invention is to provide a paper cutter using either a thick or wafer blade with means for quickly apply- 19 ing or removing the blade.

A further object, more specifically, is to provide a paper cutter wherein a portion is formed to resiliently grip a finger and an extension is provided for receiving and i5 clamping a blade in place so that part of the edge and one corner will be in functioning position at all times.

In the accompanying drawing Figure 1 is a side view of a paper cutter embodying the invention, the same being shown in positionon a hand indicated by dotted lines.

Figure 2 is a perspective view of the cutter shown in Figure 1 with parts thereof broken away for clearness of illustration,

the View being taken from the opposite side.

Figure 3 is a detail perspective view of a clamping plate embodying certain features of the invention.

Figure 1 is a side view of the blade used in Figure 1.

Fig. 5 is a detail fragmentary sectional view through Fig. 1, on line 55.

Fig. 6 is a detail fragmentary perspective view of a portion of the device.

Referring to the accompanying drawing by numerals, 1 indicates a blade having a cutting edge 2 arranged so that the corner 3 will act as the principal part of the cutting structure when the device is in use as shown in Figure 1.

. The blade 1 has been shown as a wafer blade, but if desired, a heavier blade could be used and one with one or two edges used, though only one edge would operate at a time. Go-

acting with the blade 1 is a clamp 4 for clamping the blade onto the supporting base 5 which is preferably formed integral with a carrier ring or clamp 6. The carrier 6 is preferably a substantially tubular structure of metal, provided with overlapping extensions or NEW YORK, N. Y.

though it may be bent permanently to fit the finger and then a slight resilient action will maintain a proper clamping action. The tubular member or carrier 6 merges into the base 5 and is in fact, an integral part thereof. T he base 5 is substantially triangular in shape and formed with turned over ears 11 and 12., said ears co-acting with a turned over ear 13 pressed from carrier 6 as shown in Figure 1. These ears form a passage-way for clamp 1 and ear 11 forms a back rest for blade 1 when in use. The clamp L} is provided with a flange 14 and a turned over hook portion 15. said hook portion preferably fitting snugly over the rear face of base 5 as shown in Figure 2, while the front part of the clamping plate 1 presses the blade 1 against base 5. Theear 12, as shown in Figure 1. faces to the left and, therefore, forms an abutment against which the end16 of blace 1 rests when in operative position as shown in Figure 1, and also against which the shoulder 17 of plate 4 rests. A short turned up ear 12' closes the ear 12 on the'lower edge when looking at the same as illustrated in Figure 1, but provides a support for the rear part of the cutting edge 2, as illustrated in Figure 5. The cars 11 and 13 on one side and the ear 12 on the opposite side form a pocket closed on two sides and open on two sides, said pocket receiving part of the clamping plate 1 and part of the blade 1. The hook 1'5 acts on the end 18 for holding the blade in place and against ear 12. Preferably the ears 11, 12 and 13 are resilient and are spaced from the base 5 suflicientlyto permit the plate 4 to slide therebeneath but be resiliently clamped. The flange 14 acts as a rest for the thumb when the device isin use, while the forefinger is folded and rests on the article to be cut. In this way, the knife 1 may be properly guided during the cutting operation. V

VJhenever the knife 1 becomes dull, the clamp or clamping plated maybe removed by pushing the same towards the left in Figure 1. The'blade 1 will then drop out and a new blade may be inserted, after which the V clamping plate 4 is re-applied and pressed as in a position which will permit aquick shifting of the parts so that the edge may be used 7 for cutting, while at all times the edge is out of the way of the fingers of either hand or any part of the body. I i

' What'I claim is: c 1

two of said ears and part of the opposite I edge under one of said ears, a clamping plate fittedagainst saidblade'and positioned with its edges under said ears, said plate being formed with a hook hooking over one end of said blade and also one end of said base, and with a flange adjacent the opposite end acting as a thumb rest and guide.
