FRAME FOR SASH-PULLEYS.

SPECIFICATION forming part oi Letters Patent No. 369,648, dated September 6, 1887.

Application tiled April 7, 1887.

To all whom, it may concern.-

Be it known that I, DELOs G. LYON, a citizen of the United States of America, residing at Girard, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Frames for Sash-Pulleys; and I do hereby declare 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, reference being hadto the accompanying drawings, and to letters or figures of refer ence marked thereon,which form a part of this specification.

My invention relates to certain new and useful improvements in frames for sash-pulleys; and it consists in the arrangement and construction of the parts, as will be hereinafter fully set forth,whereby the pulley for the sashcord can be readily attached and held securely in place by a single screw, as will be hereinafter fully set forth, and specifically pointed out in the claim.

In the accompanying drawings,which illustrate my invention, Figure l is a vertical sectional view of a window-pulley and its frame attached in position, the same being constructed in accordance with my invention. Fig. 2 is a detail perspective view. Fig. 3 is a section of the pulley on line x fr, Fig. l-.

To better' illustrate myinvention, and in order that the same may be fully understood, I have shown my improvement i-n Fig. l applied to a window-frame, in which viewA refers to the top jamb of the window-frame, B being the sidejamb, and C the weightbox.

In order to apply my improvement, which will be hereinafter described, the side jamb, B, is provided at a point extending from the top jamb, A, with a vertical slot, the lower end of said slot being curved, or of the same configuration as the rbase or lower lend of the metallic frame which supports. the pulley, and in order to attach my improvement to a window-frame of ordinary construction the forming of this slot is the only preparation needed. The frame of the pulley is preferably made of a malleable casting of a single piece, which is provided at its upper portion with a horizontal plate, D, which projects from Serial No. 234,042. (No model.)

the bail or loop E, between which the grooved pulley F isjournaled. The bail or loop E is U-shaped in cross-section, the lower portion, e, being preferably curved, though it may be of any other suitable shape,if found desirable, and the lower edge of this curved portion tapers slightly inward. The side pieces, E E, also taper from their front edge rearwardly. The top plate7 D, projects slightly beyond the side pieces of the pulley-support, and is centrally provided with a perforation, d, through which passes an ordinary wood-screw for attaching the same to the upperjamb.

In attaching my improved frame to the sashfra-me the slot in the side jamb, hereinbefore referred to, is formed so as to be slightly smaller than the portion E, and said portion E is then driven into this slot, and as the side pieces and bottom portion are slightly tapered it will,when driven in, be wedged securely in position, and after it is driven into the slot so that its edge will be flush with the side jamb the screw is passed through the perforation d and screwed intothe top jarnb, and said screw, with the frictional contact of the sides, will hold the frame securely in position.

I am aware that prior to my invention there existed a patent, No. 91,836, which shows a window-pulley or sash-cord guide having a tubular case which is adapted to support two pulley-wheels which are inserted therein, and I do not claim such construction as my invention, as such device is merely adapted to be attached to the sidejamb ofthe window-frame, so that the sash-cord will work over two pulleys instead of one. My invention is adapted to be applied to sash-frames as now manufac tured, and the down pressure or weight of the sash and weight attached to the sash-cord will be received by the lower end of the slot in the side jamb and not solely upon the screw, and the flat upper portion of the top plate, D, bearing against the top jamb, will prevent the frame rocking or working loose, and thelaterally-proj ecting top portions of this top plate will prevent the pulley-supporting 9 frame being driven beyond its proper position in the slot.

I claim- As an improved article of manufacture, a
