C U TT E R SPECIFICATION forming part of Letters Patent ITo. 652,133, dated Tune 19, 1900. Application filed September 15, 1899. Serial No. 730,634. (No model.)

To all whom it may concern:

Be it known that I, OHRIsToPH lVliiLLER,ca1- pet manufacturer, a subject of the King of Bavaria, residing at Frilhlingstrasse 19, M unich, in the Kingdom of Bavaria and Empire of Germany, have invented certain new and useful Improvements in Fabric-Cutting Devices, of which the following is a full, clear, and exact description.

Hitherto no suitable instrument has been introduced for the cutting of linoleum, pasteboard, paper, &c.,which would meet several simultaneous requirements.

In the cutting of linoleum for covering floors, which first comes into consideration, it frequently happens that the pieces which come into contact with one another are not straight. Asit involves a greater labor to make both pieces perfectly straight by trimming than by laying the edge of one piece on the other and then cutting the lower piece exactly according to the edge of the upper one, the latter process is preferred. In this way the pieces fit together as if their edges were perfectly straight, owing to the irregularities therein being mutually compensated, and there is not the least gap between them. In carrying out this operation it happens very frequently, for instance, that the cutter cuts into the upper piece oflinoleum serving as a rule or diverges from the proper direction. Further, it happens frequently as soon as the pressure of the hand is relaxed on the upper piece that the latter, being pressed by the cutter, is pushed out of the proper line. Finally,

it is prejudicial to the cutting edge when it cuts through the linoleum, together with the flooring on which the linoleum is rolled out, especially when the flooring is of stone. It the cutting be eifected only as far as the under piece,the cutting edge is preserved and the under piece can be easily out by an ordinary cutter. In the cutting of paper, cardboard,-

&c., similar conditions prevail. The rule or the drawing-board is often exposed to being cut. The trouble taken to avoid this leads, moreover, to the cutter being insecurely held and to improper cuttings being made adjoining the cutting-line. When the pressure on the rule is relaxed, the rule can easily slip, and in this case also improper cutting is impossible.

Owing to the cutting being often too deep the cutter is injuriously affected, as is also the cutting or drawing board. The improved cutting instrument obviates all these disadvantages and fulfils many different requirements. Itis shown in the accompanying drawings, in which- Figure 1 is a side view. Fig. 2 is an end view showing the cutterhead in section. Fig. 3 is an inverted plan; and-Figs. 4 and 5 are back and front views, respectively, of a device for facilitating the adjustment of the cutter. Fig. 6 is a sectional elevation of the cutter-head, showing the instrument in use.

Through the cutter-head it runs a groove in which the cutter I), together with a bent-wire piece 0, is placed, the two being held in the fixed position by means of a small plate d, pressed against them by means of screws, Fig. 2. The cutter can be taken out of or pushed into the bent-wire piece. The cutterhead has an oblique arm or extension co, to which the handle is fixed.

The measuring part, Figs. 4 and 5, is furnished on the side f with a vertical measuring-scale and on the side 9 with a horizontal one. The first serves for measuring the thickness of the linoleum, the second after being placed on the cutter-head, Fig. 5, being employed for adjusting the cutting edge and the ends of the bent-wire piece at a certain distance from the under surface of the cutterhead in the manner indicated below. The measuring device is widened at its upper part, forming, as it-Were, a casing, so that when placed on the cutter-head it incloses the same and is so cut away on one side that room is formed for the end of the small plate at and for the screws 6.

Assuming that the linoleum is only four centimeters thick and of two overlapping pieces the lowermost only has to be cut through, Fig. 6, the cutter must be adjusted downward accordingly,a millimeteuhowever, being deducted from the depth of the lower piece for clearance, the total depth of the cutter, allowing for the four millimeterscorresponding to the thickness of the upper piece, being thus seven millimeters from the cutterhead, as shown in Fig. 5. The ends of the bent-wire piece should project nearly as far as the thickness of the upper piece, nevertheless, with a similar deduction ofv about one meter in order that they may not graze the under piece when the cutter in cutting has reached the greatest depth and the cutterhead is pressing on the upper piece. The adjustment being effected, the cutter and bentwire piece are firmly pressed by tightening the screws 6, and the measuring-piece is removed. In the cutting operation, Fig. 6,

wherein the handle and the arm a are turned 7 cannot penetrate farther than to what is beneath the lower piece, as it prevents the out ter-head from lying on the upper piece.

If in consequence of the peculiar conformation of the room a different position of the instrument or cutter is necessary, thelatter can be turned about accordingly.

In the case of paper and the like being cut the cutter is replaced by another with an oblique edge ground for paper cutting.

lVhatI claim, and desire to secure by Letters Patent, is

A cutting device consisting of a cuttinghead supported by a suitable handle, an adjustable cutting-blade b and the bent-wire piece 0, adapted to slide within the head, means for securing the blade in position and a removable gage having scales indicated on its opposite sides, substantially in the manner set forth.

In witness whereof Isubscribe my signature in presence of two witnesses.
