STR ING AND RIBBON CUTTER Filgd Aug. 26, 1941 ao/1 n D. $23235 ATTORNEY.

Patented Feb. 23, 1943 UNITED STATES PATENT OFFICE 4 Claims.

My invention relates to a string and ribbon cutter, more particularly to a stationary replaceable razor blade string and ribbon cutter and the objects of my invention are:

First, to provide a string and, ribbon cutter of this class in which the razor blade thereof is readily and easily replaced by various standard sized razor 'blades found in almost any civilized locality;

Second, to provide a string and ribbon cutter of this class in which the cutting edge thereof is not easily contacted ordinarily preventing fingers of the operator from being cut thereon;

Third, to provide a string and ribbon cutter of this class which is readily and easily renewed by removing the old razor blade thereof and inserting a new or sharp one into the frame of my string and ribbon cutter;

Fourth, to provide a string and ribbon cutter of this class which is very sharp and easy to use;

Fifth, to provide a string and ribbon cutter of this class which is small and compact, yet strong enough to out various sized large twine;

Sixth, to provide a string and ribbon cutter of this class the frame of which is formed of one piece of sheet metal for strength and compact construction thereof;

Seventh, to provide a novel string and ribbon cutter of this class; and

Eighth, to provide a string and ribbon cutter of this class which is very simple and economical of construction, efiicient, durable and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon which form a part of this application in which:

Figure 1 shows a blank from which the frame of my string and ribbon cutter is formed; Fig. 2 is. a side elevational view of my string and ribbon cutter; Fig. 3 is a sectional view taken from the line 3--3 of Fig. 2 and Fig. 4 is an edge view thereof.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawing.

The frame I and the razor blade 2 constitute the principal parts and portions of my string and ribbon cutter.

In the construction of my string and ribbon cutter, the frame I is formed of sheet metal or any other suitable material. In the construction of the frame I, a blank, as shown in Fig. 1 of the drawing, is first formed of thin flat sheet metal or the like and this blank, as shown in Fig. 1 of the drawing, has substantially duplicate portions on opposite sides of the middle thereof. These substantially duplicate portions Ia and lb of the blank, as shown in Fig. l of the drawing form opposite sides of the frame I, as shown in Fig. 2 of the drawing.

The blank, as shown in Fig. 1 of the drawing is folded along the broken middle line A whereby the portions Ia and lb are folded substantially against each other leaving a slight space therebetween to receive the razor blade 2. The tab portion I c is folded over the guard portion Id at its' upper end portion I c, it being noted that the tab portion I0 is integral with the guard portion I f and that the guard portions If and Id are secured together in connected relation to each other by the tab portion Ic over the portion Ie of the guard portion Id, as shown best in Fig. 3 of the drawing. The tab portion IQ is folded over the edge portion In of the razor blade retaining portion I k, as shown best in Figs. 1 and 3 of the drawing, it being noted that the tab portion la is integral with the razor blade retaining portion I1 and that the razor blade retaining portions lie and I7 are securely connected together by the tab portion lg which is bent over the outer side of the razor blade retaining portion I k at the side edge Ih thereof, as shown best in Fig. 4 of the drawing. Intermediate the razor blade retaining portion I9 and the middle of the blank, as shown in Fig. 1 of the drawing, is a cutaway portion I m. The blank is also provided with'a cutaway portion In on the opposite side of the middle from the cutaway portion Im. These cutaway portions Im and In are arranged to provide an open space in the frame member at each opposite side of one end of the razor blade 2. These open spaces provided by the cutaway portions I m and In permit the operator of my string and ribbon cutter to grasp the razor blade 2 when in the frame I and remove the same or adjust the same as desired.

The 'blank, as shown in Fig. 1 of the drawing, is also provided with cutaway portions Ip and la. These cutaway portions I p and Iq are positioned inwardly of the guard portions If and Id and these cutaway portions Ip 'and Iq provide a slotted portion in the frame I arranged to admit string or ribbon to be cut on the edge portion 2a of the razor blade 2, all as shown best in Figs. 1 and 2 of the drawing. It will be noted that the razor blade retaining portions Ii and Us form one side of the cutaway portions lp and Iq providing a guard at the one end of the razor blade 2 at its cutting edge 2a. The blank, as shown in Fig. 1 of the drawing, after it has been folded along the broken line A is then bent at a right angle forming the L -shaped in cross section form as shown in Fig. 3 of the drawing providing a base portion Ir arranged at a right angle to the guard portions Id and If, all as shown best inFig. 3 of they drawing. The razor blade 2 is a substantially conventional safety razor blade and may be provided with a single cutting edge or this razor blade 2 may be provided with two cutting edges as desired, both features are conventional in the construction of standard razor blades and the frame I is arranged to retain various standard razor blades 'as desired. The base portion I1- of the frame I is arranged to be secured on a counter, desk or any suitable surface by means of the screws B as shown by .dash lines in Figs. 2 and 3 of the drawing. These screws B extend through openings Is and It in the base portion "11', all asshown best in Fig. 4 of the drawing. It will be here noted that the base may be secured by any means desired.

When it is desired to cut string or ribbon using my string and ribbon cutter which is secured as hereinbefore described, the operator holds the string or ribbon with his hands and forces the portions of the string or ribbon against the cutting edge 2a of the razor blade 2 and the string or ribbon is easily guided and severed.

Though I have shown and described a particularconstruction, combination and arrangement of parts and portions, I do not 'wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a string and ribbon cutter of the class described, the combination of a stationary frame and a conventional razor blade in "connection therewith, said frame including side portions at opposite sides of said razor blade extending past the cutting edge of said blade and guard portions extending in angular relation with and forwardly of thecutting edge of said razor blade and spaced therefrom, said frame L-shaped in cross section, said opposite side portions secured together by overlapped tab portions.

2. In a string and ribbon cutter of the class described, the combination of a stationary frame and a conventional razor blade in connection therewith, said frame provided with opposite side portions having guide portions extending past the cutting edge of said blade and tab portions on said side portions overlapping said side portions.

3. In a string and ribbon cutter of the class described, the combination of a stationary frame therewith, said frame provided with side portions engaging opposite sides of said razor blade, said side portions provided with cutaway portions at opposite sides of one end of said razor blade to facilitate the removal of said blade endwise, guard portions integral with said frame and extending in diverging upwardly spaced relation with the cutting edge of said razor blade.
