SASH-PULLEY.

SPECIFICATION forming part Of Letters Patent N0. 787,517, dated April 18, 1905.

Application filed February 16, 1904. Serial No. 193,805-

To all whom it 77710, concern:

Be it known that I, KARL KERR, a citizen of the United States, residing at Victor, in the county of Iowa and State of Iowa, have invented a certain new and useful Sash-Pulley, of which the following is a specification.

The objects of my invention are to provide a sash-pulley of simple, durable, and inexpensive construction which can be easily attached to and held, firmly in position relative to the ordinary window-casing.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of two of these pulleys attached in position on the windowcasing. Fig. 2 is a rear elevation of the same, showing the way of attaching the pulleys and holding them in position relative to the window-casing. Fig. 3 is a vertical sectional view of the casing, showing that part of the pulley which is not hidden by the case in side elevation; and Fig. 4 is a sectional view of the pulley cut on the line 4 1 0f Fig. 3, with the pin for holding the pulley in position relative to the casing removed.

Referring to the accompanying drawings, I have used the reference=numeral 10 to indicate the window-casing, having the ordinary groove 11 extending through its central portion for maintaining the retaining-strip in position. Extending through this casing 10 are two openings, each of which is of sufiicient size to admit the pulley-frame hereinafter described. frame and midway between the upper and lower ends of these openings is a groove 12, in which the pin for maintaining the pulleyframe in position is designed to be mounted. The pulley-frame is preferably made of a single piece of sheet metal 13, which is folded entirely around the pulley-wheel l4, and this frame is made of such shape that the pulleywheel 14: will rotate freely from the sides of the frame and the end portions thereof,

jacent to the forward edges of each of the sides is a slot 15, into which the retaining- Extending across the back of the plate 16 is designed to be hooked,'so as to maintain the retaining-plate 16 in position relative to the body portion 13. The front of the plate 16 is designed to extend substantially at right angles to the sides of the body portion 13, so that the inner surface of these plates when the pulley-frame. is in position relative to the casing will rest against the outer surface of the casing 10.

Extending transversely of the pulley-frame with its ends riveted to the sides of said frame 13 is the hollow axle 17, having the flanges 18 and 19 at its outer ends, said flanges being designed to hold the hollow axle in position relative to the frame 13. The wheel 14 is rotatably mounted on this hollow axle. When the pulley-frames 13 are placed in position in the slots in the upper portion of the casing and stand in the position shown'in Fig. 1 of the drawings, so that the plate 16 rests against the front surface of the casing, the opening 20 through the hollow axle 17 will come directly in line with the groove 12 on the rear face of the casing. The pin or nail 21 is then slipped into the groove 12 and through the opening 20 in the hollow axle 17. This pin is designed to hold the frame 13 and the pul-v ley-wheel 14 firmly in position relative to the casing 10 and to hold the plate 16 firmly against the front face of the casing 10.

In practical use it will be seen that this device is advantageous, owing to the fact that no screws have to be used in the front face of the casing and that an absolutely rigid means of holding the pulley in position is provided.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is-

The combination of a pulley-frame designed to enter a slot in a window-casing and formed with a stop to limit its movement into the slot, a hollow axle in the pulley-frame, a pulley rotatable on the axle and a pin designed to pass through the hollow axle and be non-rotatably supported by the window-casing to firmly hold the pulley-frame in position in the casing.
