RULER FOR CUTTING CLOTH 0N THE Bil i SPECIFICATION forming part of Letters Patent No. 784,079, dated March '7, 1905.

Application filed October 17, 1904. Serial No. 228.860.

Be it known that I, HUGOA. S'rnMrnL, a citizen of the United States oi America, and a resident oi Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Rulers i orCutting Cloth on the Bias, of which the following is a specification.

The main object of my invention is to provide an improved device for cutting cloth on the bias having a straight edge for guiding a cutter, having means For hold the cloth and preventing the same from shifting during the act of cutting, and provided with a scale adapted for measuring away from the cutting edge oi the ruler and along the sclvage oi the cloth.

I accomplish this object by the device shown in the accompanying drawings, in which-- Figure 1 is a plan view oi adevice constructed according to my invention. Fig. 2 is a transverse section on the line 2 2 oi Fig. 1.

in the construction shown in the drawings three flat strips of thin wood or other mate rial are rigidly secured together, lying in the same plane with each other, as shown in Fig. 1, to form the triangular frame. The strips 1 and 2 have their ends secured together to form a right angle at 3 and are also connected together by the strip 4, which makes an angle of forty-five degrees with each of the strips 1 and 2. The strip 2 is extended a considerable distance beyond the oblique strip 4 and is graduated, as will be hereinafter described.

All of the edges are preferably straight, and the graduations on the strip 2 are numbered each way from the adjacent ruling edges or 6 of the strip 4, the zero-mark coinciding with the corresponding ruling edge in each case.

The strip 4 is provided with a plurality of pins 7, which project from both sidesof said strip transversely to the plane of the triangle and are adapted to enter the material which is being cut and prevent distortion of the same during the act of cutting. Recesses 8 are cut into the edge 9 of the strip 2 in alinement with each of the edges of the strip 4, so that when the device is used for cutting cloth with a rotary cutter the cutter may enter one oi said recesses and cut through the edge of the i cloth. The function of the strip 1 is to ln'ace the strips 2 and 4 and at the same time render the d evicc use iul as an ordinary tailors square.

in the operation of cutting the cloth with the device shown the ruler is laid upon the cloth, with the edge 9 lying along the solvage edge oi? the cloth. The strip 4 is now pressed down, so as to cause the pointed pins 7 to enter the cloth, and the cutter is then drawn along one oi the edges of the strip 4, cutting the cloth at an angle of forty-live degrees with the selvage edge. The graduations on the extended part oi the strip 2 are numbered toward the top of the sheet in Fig. 1 and measure distances from the cutting edge Sin'iilarly the graduations at the le'it of the edge (5 are numbered toward the bottom of the sheet for measuring i'rom the cutting edge (3. It will be urulerstood that both 'i'accs oi the strip 2 are graduated, so that either cutting edge of the strip 4 may be used when cutting along either selvage edge oi the cloth, the device being thus useful in whatever position is most convenient for the operator at any time.

if, for example, the operator wishes to cut a bias strip three inches wide, he would lay the graduated edge 9 along the sclvage oi the strip in such position as to bring the graduation numbered 3 even with the end of the cloth or with the previous out. A out along would then out oii a strip three inches wide, measuring along the scivage as such cloth is usually sold.

It will be seen that some oi the details oi the construction shown may be altered without de iiarting from the spirit oi my invention.

What .I claim as my invention, and desire to secure by Letters Patent. is--- 1. A device oi. the class described, comprising a ruler having two straight edges, one oi said edges intersecting the other obliquely and intern'iediate of its ends, and said other edge being recessed in alinement with the iirst edge and being graduated to measure distances from the point of intersection of said edges, substantially as described 2. A device oi the class described, compris ing a ruler having two parallel straightedges the corresponding cutting edge oi the strip 4 intersecting a third straight edge obliquely and intermediate of its ends, and said third edge being recessed in alinement with each of the other edges and being graduated to measure distances in opposite directions from the points of its intersection with said other edges, substantially as described.

3. A device of the class described, comprising a pair of straight strips rigidly secured together and having ruling edges oblique to each other, one of said strips having thereon a plurality of pointed projections extending transversely of the plane of said strips, and the other strip being graduated to measure distances from the point of its intersection with the first strip, substantially as described.

4. A- device of the class described, comprising three strips rigidly secured together to form a triangular frame having two sides at ing three strips rigidly secured together to form a triangular frame having two sides at right angles to each other, and a third side oblique to the other two, one of said sides being extended beyond the oblique side, and said extended side being graduated for measuring in opposite directions from the points of its intersection with the ruling edges of said oblique side, substantially as described.

oblique strip having thereon a plurality of pointed projections extending transversely of the plane of said strips, and said extended side being graduated to measure distances'froni the point of its intersection with the edge of said oblique side, substantially as described.
