" Application September 10, 1943, Serial No. 501,859
' (o1. .ao-294) 6Claims.
In the-"cutting and laying of wall linoleum, it is j desirable that the joints between the sections be lapped so. the `seam is practically indistinguishableand'theprirnary object of my invention is to provide a tool for cutting the linoleum with bevelededges so thatsuch a seam may be formed wheny the linoleumis laid.
Afurtl'ier object of my invention is to provide a ,simple iormofhand'operated tool for this purpose.
Another object of my invention is to provide a hand operated cutting tool of the draw-cut type which when engaged with the linoleum automatically positions the cutting blade to produce abevel cutinuse. "1'
Still a further object of my invention is to provide a tool of this character with a separate cutting blade that is removably and adjustably mounted therein.
Still another object of my invention is to provide a tool of this character that is adapted to use fragments of old safety razor blades as the cutting blades.
Other and further objects of the invention will be apparent from a detail description thereof, wherein only a preferred form of embodiment of the invention is shown and described, reference being had to the accompanying drawing, forming a part hereof, in which:
Figure 1 is a side elevation of my tool with the front edge of the draw head engaging a line indicating the top of the work;
Figure 2 is a bottom plan view of the tool with head sections open to receive a cutting blade; and
Figure 3 is a front end view of the tool in cutting position on the work.
The tool is of the hand operated draw cut type and includes a handle I, generally formed of wood, in which is mounted a projecting metal shank 2 riveted in the handle and having the conventional metal ferrule 3. To the end of the shank 2 is secured the draw head of the tool designated in its entirety by the numeral 4. This head carries the cutting blade 5 in a manner to be hereinafter more fully described.
The head 4 is flat and in general configuration tapered at one end. The head 4 is formed of two sections 6 and 1 which in effect form clamping jaws to hold the cutting blade 5 therebetween as clearly shown in Figure 3. The sections are loosely secured together adjacent the tapered end of the head on a pin 8. This permits the sections at the front or work engaging end of the head to be swung away from and toward each other to permit the insertion and clamping of the cutting blade 5. A screw bolt '9, mounted in the section 6, extends through and beyond the section l. A wing nut Ill is threaded on the projecting end of the bolt to removably clamp the blade 5 in position in a manner that ls obvious.
The edge of the section 6, adjacent the section l, of the head 4, is undercut as shown at II to receive the end of the handle shank 2 and is rigidly secured thereto by a rivet I2. It will be noted in the form shown, the head 4 is inclined with respect to the handle I and the front edge of the shank 2 is correspondingly inclined as clearly shown in Figure 1.
The front edge of the draw head 4 is transversely beveled as shown at I3 and rearwardly inclined at I4. This is the edge of the head that engages the work and the transverse bevel is best shown in Figure 3. The rearward incline I4 of the front edge of the head 4 is clearly shown in Figure 1 wherein the dotted line I5 indicates the top of the work along which the tool is drawn. It will be noted the edge I4 is parallel with the longitudinal axis of the handle I, when the tool is in operative position.
The blade 5, used with this tool, is very thin and may be a fragment of a safety razor blade. By the means employed for clamping the blade in the head 4, it may be easily removed therefrom to replace the blade when necessary. Also the blade is adjustable lengthwise between the sections 6 and 1 according to the depth of cut desired which depends upon the portion of the blade projecting from the head.
In use, the tool is positioned on the work comprising in this instance superposed layers of linoleum I6 and I'l, as diagrammatically shown in Fig-ure 1, and more in detail in Figure 3. The projecting portion of the blade 5 in thisI position cuts into the linoleum. One side of the head engages a ruler or other straight edge I8. When the front edge of the head engages the linoleum, the portion I4 lies flat thereon and the handle l is substantially parallel with and spaced from the work. The transverse bevel I3 tilts the head 4, as clearly shown in Figure 3, and consequently the blade 5 is tilted with the head. When the tool is drawn along the straight edge I8 with the blade passed into the superposed layers I 6 and I1 of linoleum, a beveled edge cut results. The bevel cut may be varied according to the transverse bevel I3 to vary the inclination of the edges of the cut linoleum. It is obvious that layers of linoleum cut as described may be laid with lapped joints and the resulting seams are highly desirable in laying wall linoleum,
While this tool is particularly designed for forming lap seams for linoleum, it is adapted for other uses where a beveled or inclined edge is desired. The tool is so balanced* and proportioned that it is very eective in operation and the'fact the cutting blades may be made of discarded safety razor blades is an important fea-- ture tending to enhance the economy of operation. With this tool, layers of linoleum may be easily beveled before being laid to. produce the desired lapped -seams or joints with slight effort or loss of time.

2. A device ofthe character described including a draw head of appreciable width and thickness havingronc edge adapted to engage the work, a draw-handle for said head, a blade projecting from the work engaging edge of the head, and saidedge being'ftransversely,beveled to tilt the head and blade laterallyto'produce a bevel cut.
