LINOLEUM-CUTTEB.

- the following to be a full, clear, and exact description of the invention, such as will enable others skilled in -the art to which it appertains to make and use the same.

This invention relates to improvements in cutters, and it has more particular reference to a device of this class which is especially designed for cutting linoleum, oil-cloth, and the like.

One object. of the invention is to generally improve upon devices of this class by producing one of extreme simplicity which 1s effective in operation. easy to mampulate,

and inexpensive to both the manufacturerand the user. i

. Another object of the invention is to provide a cutter of this type which includes a stationary cutter for the thinner materials and a rotatable cutter for the heavy materials such as beaver-board and the like,

the last named cutter being removed when the stationary cutter is being used.

Other objects and advantages of the invention will be apparent during the course of the, following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a side elevation of a cutter constructed in accordance with my invention.

' Fig. 2 is a top plan view thereof.

Fig. 3 is a longitudinal sectional view taken on the line 33 of Fig. 1, looking in the direction of the arrows.

Figs. 45 and 5 are sections taken on the lines 4-4 and 55 respectively of Fig. 1;

Fig. 6 is a View like Fig. 1' with the rotary cutter removed.

11 carrying out my lnvention I employ 'a vertically disposed plate 1, at the bottom of which and on opposite ends of which are secured by suitable means, a pair of strips of metal 2 which extend beyond the front edge of the plate. a base which is adapted to be moved along the floor, and for the purpose of guiding the material onto the upper surface thereof and These strips constitute Specification of Letters Patent. Patented Sept. 20, 1921.

Application filed July 1, 1920. Serial No. 393,287. i

into engagementwith the cutting edge 3 of the plate, they are tapered downwardly at their outer ends as indicated atl. If desired, the cutting edge 3 may be curved in the manner shown to insure efi'ectiveengagement thereof with the article to be out. For the purpose of sliding the device along the floor, I provide a suitable handle 5 which is preferably secured to the rear end of the plate.

It has been before intimated that my improved device includes two separate cutters, one of which is stationary and the other of which is rotary. It is tobe stated here that the stationary cutter which is the plate 1, is to be operated by hand. On the other hand, the rotary cutter yet to be described,

is intended to be used when the stationary cutter is not being used. This rotary cutter j isin the form of a disk 6, the same being carried by a pair of strips 7 detachably secured on opposite sides of the plate 1 adj acent the upper end thereof. These strips 7 are preferably pivoted as at 8, and are provided adjacent their rearends with holes ing different thicknessesof linoleum. The.

rotary cutter may be operated manually, or

it may be operated by a suitable motor which may be connected to it in any way. In order to permit use of the motor, it will be necessary, of course, to employ a different kind of journal from that shown, and to equip this journal with apulley or the like.

In cutting ordinary linoleum and oilcloth, I sometimes use the rotary cutter, and other times remove it and use the stationary cutter.

The operation of the device is as follows:

Assuming that the rotary cutter has been removed, as shown in Fig. 6, it will be seen that the tapered. portion 4 of the base of the cutter is forced underneath the edge of the linoleum or other article to be out. Then, by pushing the device forward, the linoleum will ride up and over the strips 2 and will come into engagement with the cutting edge 3 of the plate 1. The operator will then find it advantageous to place one hand down on the linoleum and hold it steady while he pushes the cutter along with the other hand. In this manner, the linoleum may be. cut on a perfectly straight line very easily and without a greatv deal of effort on the part of'the operator. Due to the curvature of the cutting edge, the linoleum will be retained in effective engagement therewith and will be prevented'from'riding up as it would if the cutting edge were straight or inclined downward and toward the front end of the base. As before stated, I sometimes find' it necessary and advantageous to use the rotary cutter instead of the stationary cutter. When the rotary cutter is being used, it may be adjusted'to the proper position to effectively sever different thicknesses of linoleum in the manner already described. The spaced strips 2 whichconstitute the base of the device also form a recess for the reception of the cutting edge of the disk, that is, the extended portions of the strips serve in, this manner.

From the foregoing description taken in connection with the accompanying drawings, persons skilled in the art to which this invention appertains will be enabled to obtain v a clear understanding of the same, therefore, further description is deemed unnecessary. 7 I

' Since probably the best results may be obtained with the construction and arrangement herein described and shown, I prefer to employ such construction.

\ wish it to be understood that various minor changes in the shape, size, and arrangement of parts may be resorted to without ,departing from the spirit of the invention or the scope of the subjoined claims;

I claim: v

'1. A cutter of the character described, comprising a blade disposed in a vertical However, I

plane and havin an operating handle at its rear end, the front end of said blade being sharpened, a pairof strips securedto opposite sides of said blade at the lower edge of .the latter, said strips extending forwardly from the blade and being beveled 2. A cutter of the class described com- 7 prising a vertically disposed plate having its front vertical edge sharpened to provide a cutting edge and being provided ad-' jacent its upper edge with a vertically elongated slot, strips arranged on opposite sides of said plate near the lower edge of the latter and having their lower fiat faces flush with the lower edge and being extended beyond thefront vertical edge of the plate and being spaced apart, the upper faces of the strips at this end being beveled so as to lift the linoleum up and cause it-to i ride rearwardly over these beveled facesand into engagement with one'of the cutters, strips mounted on opposite sides ofthe upper portion of the plate and extending beyond the front edge thereof, beingpivoted intermediate their ends on the plate and being provided at their rear ends with holes alined with the aforesaid slot, a V

clamping bolt passing through the holes in said strip and through said slot, anda rotary disk cutter rotatably mounted between the forward extendingends of said strips'and having its cutting edge received: between the first named strips. p

In testimony whereof I have hereunto set my hand.
