PAPER CUTTER Filed Jan. 11, 1933 Patented Apr. 2, 1935 PAPER CUTTER August Wedekind, Chicago, 111. Application January 11, 1933, Serial No. 651,093

5 Claims.

My invention relates to paper cutters, and more particularly to a simple, inexpensive paper outter for cutting wall paper along a straight edge.

The objects of the invention are to provide a 6 simple and eflicient paper cutter that may be used with a straight edge in cutting wall paper, for example; to provide such a cutter of light weight so that it can conveniently be manipulated by hand; to provide such a cutter that may use dis- 10 carded razor blades of the well known wafer type; to provide such a blade holder that will permit adjustable setting of the blade to enable utilization of all four cutting edge corners for paper cutting service; to provide an adjustable gauge for the cutting corner of the blade; and, other objects, which will become apparent to those skilled in this art, as the disclosure is more fully made.

In the accompanying sheet of drawings is illustrated a practicable example of my invention, the same comprising briefly a hand hold body designed to carry a cutting blade of the safety razor wafer type, said body, or holder, having means to hold the blade in a manner to present one comer of the blade at a time along a straight edge for paper cutting duty, thus making available for eventual use, all four corners of the blade. The holder is designed to be guided along the conventional paper hangers straight edge, and a gauging feature for the knife is also provided.

In this drawing:

Figure 1 is a general perspective view, show ing the improved paper cutter cooperating with a straight edge;

Figure 2 is an end view of the cutter and straight edge:

Figure 3 is a longitudinal, central, sectional view through the cutter and straight edge, as seen along the line 3-3 appearing in Figure 2;

Figure 4 is a front elevational view of the cutter and straight edge; and,

Figure 5 is a transverse cross sectional view through the straight edge and cutter as seen along the irregular section line 55, appearing in Figure 4.

A conventional straight edge, such as commonly employed by wall paper hangers, is shown at I 0, the same having a longitudinal groove ll adjacent one edge, to provide the usual marginal shoulder l2.

The improved paper cutter has been designed to cooperate with such a straight edge, and comprises a sheet metal hand hold, or holder body I3, bent generally into inverted U-shape and having one leg or side of the U of greater length,

or depth, so that it will overhang the edge of the straight'edge, as shown at M in Figures 1 and 5 especially. A'second, simple sheet metal piece completes the holder, said second piece comprising a Z-shaped form I 5 coextensive in length 5 with the piece I3 and having one leg arranged vertically and secured by two screw bolts l6 to the side l4 of the main holder I 3, as shown in Figures 1 and 2, the piece l5 being located within the part l3 as shown in Figure 5. The other ver- 10 tical leg of the Z piece l5 completes a leg of a channel form with the overhang I that spans the shoulder l2 of the straight edge Ill. The connecting web between the two legs of the Z piece I5 is disposed horizontally and a slight dis- 1 tance above the shoulder l2. Said horizontal web portion has secured to its under side a fiat spring I! the ends of which serve as gauge runners that ride on the shoulder I2. Screws l8 are adjustably set in the ends of the horizontal web of the Z 20 piece l5 to limit the downward movement of the holder when it is pressed against the straight edge shoulder l2. Holes l9 are provided in the top edge of the holder or body l3 to allow of easy access to the screws l8 with a screw driver when 25 it is desired to change the set of the screws l8. These holes l9, as shown, are in vertical alinement with the screws l8.

While any suitable type of cutter blade may be employed, it is especially intended, for the sake 30 of economy, that discarded razor blades of the common wafer type be employed, such a blade being shown at 20 in Figures 1 and 2, the blade being rectangular and having two cutting edges, so that when it is tilted in the manner shown, 35 one corner only is presented for cutting duty. By this expedient then, each blade presents four corners, thereby increasing the usefulness and life of the blade. These blades have a hole in each end thereof for mounting on the locator pins of 40 a razor. Such holes are indicated in Figure 1 at 2|. The wall or side l4 carries two screws 22 only one of which is passed through a hole 2| of the blade to lock the blade between the inside face of the wall l4 and the adjacent vertical 45 portion of the Z-piece IS, the blade being tilted at an angle so that the top edge of the far end of the blade seats under and stops against the other screw 22, as shown. This form of mounting presents a cutting edge corner of the blade at 50 23 below the lower edge of the overhang or wall I 4 for cutting duty. By pressing down on the holder the spring legs l'l serve as gauges to project the cutting edge comer just enough below the plane of the straight edge bottom to perform the proper cutting action. When the cutting corner a has worn, then the blade can be tilted in the opposite direction as shown in Figure l, the function of the screws 22 then being reversed. By turning the blade over, the other two corners thereof may also be used in an obvious manner.

Only one blade is used at a time and the dotted line showing of the blade in Figure l is intended merely to illustrate two positions of the same blade.

Another common form of safety razor, wafer blade employs cut out corners as shown in Figure 4 and to adapt the holder of this invention for use with such blades a slot 24 is provided in the wall I to carry a screw bolt 25 which serves as a means to increase the angle of tilt of such a blade to present its cutting edge below the plane of the straight edge. In this case, the screw 25 merely supplants the other screw 22 as a stop.

In use the blade is mounted as described and the holder is then run by hand along the straight edge shoulder I2 to cut wall paper, and the like, lying on a table below the straight edge. The depth of cut of the corner or end of a blade is gauged by the ends of the spring I1, such gauging effect being adjustable by means of the screws l8 accessible through the holes I9.

The Z-piece and U-holder thus form a guard for firmly holding the blade close to the straight edge, prevents buckling of the wafer blade; and protects the users hand from accidental cuts. Further, the point of cut of the blade is adjustable by controlling the tilt thereof by the clamp screw and an adjustable gauging efiect is enabled as described by means of the adjustable spring runner gauge.

From this disclosure it will now be clear that an improved paper cutter has been provided, which achieves all of the desirable objects heretofore recited.

It is the intention to cover all such changes and modifications of the form herein chosen for purposes of illustration which do not depart from the spirit and scope of the invention as indicated in the following claims.
