Application filed September 20, 1915, Serial lie. 51,644.

To all whom it may concern:

Be it known that l, EARNEST H. MILLER, a citizen of the United States, residing at Ladysmith, in the county of Rusk and State of lVisconsin, have invented a new and useful Window-Shade Trimmer and Roller- Cutter, of which the following is a speci iication.

My invention relates to the trimming of one edge of the shade after it has been wound around the shade roller with one edge of the shade at a determined distance from one end of the roller, said end being in those fixtures that have a spiral spring one end, such as may be seen in the commonly used Hartshorns patent spring roller, and then cutting the shade near the opposite end of the roller of the proper width for the window to which it is to be applied, and also, in sawing off the roller at the last named end the same distance from the trimmed edge of the shade as it is around the roller at the other, or spring end thereof; and it consists of a light frame formed principally of wood, upon which the shade when wound upon the roller as above described, can be placed and firmly held, an adjustable gage for the desired length of the roller and of the width of the shade, and a knife block and knife therein and a saw receiving slot in said block.

The device is shown in the accompanying drawing in which,

Figure l is a side elevation of the device with a part broken away, showing a roller and shade wound thereon in position for being trimmed and cut. Fig. 2 is a plan of the frame. Fig. 3 is an end elevation of the frame at the right of the line a, a, of Figs. 1 and 2. Fig. l is a vertical section of the knife holding block as it appears when looking toward the left of the line b, b, of Fig. 3. Fig. 5 is an end elevation of the support for the shade and roller mid way its ends while the shade is being trimmed and the roller cut the required length. Fig. 6 is a side elevation of the shade trimming knife upon a larger scale than previous figures. Fig. 7

is a vertical section through the knife block upon the line 0, 0, of Fig. 1.

roller in the present case extending some distance outside of the shade. 3, a gudgeon pin upon which the roller revolves; 4, feet of the frame; 5, two strips arranged parallel and connecting the two feet; 6, the knife block which serves as a support for one end of the roller; and 7, a support for the roller intermediate its ends. This support is made to slide toward and from the knife block by means of the connecting piece 8, which is tted to slide through the foot piece 4 as is shown in Fig. The collapsible feature is for saving storage space when the frame is not in use. The piece 8 can be held in any desired position by means of a thumb nut and bolt 9.

10, is a stop piece for gaging the length of the roller; 11, a thumb nut and bolt for securing the piece 10 in the desired position; and 12, a tongue depending from the piece 10 and between the strips 5 for holding said piece parallel with the strips as shown in'Fig. 1.

As rollers of any one shipment are usually of a uniform length and the part to be cut olf is of less length than the part used, the end to be cut off has been provided with a gage, but I do not confine the use of the gage to any one end of the roller. The block 6 is secured upon the strips 5 and is provided with an aperture 13 for receiving the shade and roller.

The aperture is made circular around its upper half, but its form in that half is immaterial. The lower half forms approximately a right angle at its lowest point. This angular form is for the purpose of providing a firm rest for the round shade while it is being trimmed and the roller sawed oli". The same angular form may be applied to the upper end of the piece 7, although it is not as essential as in the knife block. For trimming the shade the desired width a knife 15 is employed. It will be observed that instead of being a straight blade with its pivotal point in the straight part that it is angular and is pivoted through its angular extension, and consequently, the downward movement of its handle will produce a shearing out upon the shade and leave a A pivotal pin 17, is provided for insertion into the aperture 18 in the knife block and the blade is provided with a handle 19 and cutting edge 20, the actual cutting part being between the points 03, d.

The point upon the shade upon which it is desired to out the shade in trimming it can be made with pencil before the shade and roller are placed within the aperture 13, and the block is cut out at 22, from its top downward to the aperture 18 for the operator to adjust the mark on the shade to the slot 23 in which the knife is arranged. A slot 2a is provided for receiving a saw with which to cut the roller. The shade is trimmed after being marked and placed within the aperture 18, by swinging the knife by its handle with one hand while with the other hand the shade is turned about 1 6 of an inch at each upward movement of the knife until the roller and shade have been turned a complete revolution. After the shade has been cut, the out OK portion is to be removed. This can best be done by removing shade and roller and pulling on the cut oil portion. After its removal the shade and roller are to be replaced in the same position as before and with a line tooth saw inserted in the slot 2% the roller is to be sawed off. This completes the operation and the roller and shade can be removed and another inserted for a like operation.

Having described my invention, what I claim and desire to secure by Letters Patent, is,-

l. A window shade trimmer and roller cutter comprising a frame, a block mounted upon said frame and having an aperture therethrough for receiving said roller with a shade wound thereon and being adapted for supporting said roller and shade therein the lower half of the inclosing walls of said aperture terminating in an approximate right angle at the lowest point thereof, a support for the roller and shade at a point between said block and the end of the roller that is to remain uncut having an open top a stop for gaging the width of the shade and length the roller is to be cut adjustable toward and from said block, said block having slots arranged parallel with each other across the roller and spaced apart the distance the roller is to be cut off beyond the edge of the shade, a knife blade and a handle thereto pivotally mounted between the side walls of one slot and arranged to trim the shade by an upward and downward movement of the handle thereof and the side walls of the other slot being spaced apart for receiving a hand saw to be reciprocated therebetween for cutting off said roller.

2. A window shade trimmer and roller cutter comprising a frame, a block mounted upon said frame and having an aperture therethrough for receiving said roller with a shade wound thereon and being adapted for supporting said roller and shade therein, a support for the roller and shade at a point between said block and the end of the roller that is to remain uncut, having an open top, a stop for gaging the width of the shade and length the roller is to be cut adjustable toward and from said block, said block having slots arranged parallel with each other across the roller and spaced apart the dis tance the roller is to be cut off beyond the edge of the shade, a knife blade having a iandle at one end and an angular termination at the other pivotally mounted between the side walls of one slot at a point above the transverse center of the knife blade and beyond a line passing vertically through the roller and arranged to trim the shade by an upward and downward movement of the handle thereof, and the side walls of the other slot being spaced apart for receiving a hand saw to be reciprocated therebetween for cutting off said roller.
