Serial No. 594,249.

o all whom it may concern:

Be it known that I, HENRY G. VOIGI-IT, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Overhead Sash-Pulleys, of which the following is a full, clear, and exact description.

This invention relates to improvements in overhead sash pulleys, and the main object is to provide an improved construction which is so adapted to a window casing that it may readily be applied thereto after the casing has been set up, the same furnishing a neat and finished appearance when in place.

In the drawings Figure 1 is a side elevation of the device as it appears in place. Fig. 2 is an end elevation of the parts shown in Fig. 1 looking from right to left. Fig. 3 is a View similar to Fig. 1, the pulley being shown as partly inserted in the act of assembling. Fig. 4 is a plan view. Fig. 5 is a plan view of the upper corner of a window casing recessed, or mortised, in a manner suitable to receive the pulley.

1 represents the head jamb, or lintel, of a window casing; 2 represents the side-stile, these parts meeting in the usual manner -to form a right angle. The meeting ends of the lintel 1 and the side stile 2 are recessed, or mortised, to form a passage at the corner through which the pulley is passed and in which said pulley stands when the parts are assembled ready for use. The major part of the mortise is preferably formed in the lintel 1. The main passage formed by the mortise, or notch, in the lintel 1 is indicated at 3 (Fig. 5). The mortise or notch in the side-stile is preferably provided with two side shoulders 4--4, which when present may constitute supporting ledges, the space between said shoulders being to afford clearance for the pulley hereinafter described. The rear end of the mortise in the top stile is preferably undercut, as indicated at 5 (Fig. 3) to receive the tail end of the upper part of the pulley frame later described.

The construction of the pulley and its frame is substantially as follows: 6 represents the pulley wheel of any suitable design, usually having a grooved peri hery. This pulley 6 is mounted on a pivot carried by a frame 8. The frame 8 is provided with an exposed and finished under surface 9. The two edges of the frame, indicated at 1011 respectively, are preferably substantially parallel and extend obliquely to the under surface 9. 12 is a depending ex- Patented Dec. 5, 1911.

tension or arm constituting part of the frame and arranged at right angles to the surface 9. The part 12, when in place, faces against the side-stile 2. The passage formed by the notches in the head-jamb and sidestile is of such size as to permit the pulley and its housing to be passed through the same diagonally, as shown in Fig. 3, so that said frame and pulley may be inserted from the exposed side of a window frame after the latter has been set up. When the frame and pulley are finally in place, as shown in Fig. 1, the angular exposed part of the frame will lie flush with the surfaces of the head-jamb and. side-stile. 14- is a holding screw by which the arm 12 may be secured to the side-stile 2. If desired, another holding screw 15 may be passed through the other exposed. end of the frame so as to take into the top lintel 1. The pivot 7 for the pulley will, when the parts are assembled, stand above the side-stile 2 and preferably slightly outside of a center line passing therethrough, so that any tendency of any weight suspended by the pulley 6 would tend, if anything, to tilt the frame in a di rection to lift that end located in the undercut recess 5, while the weight will be carried by the support afforded to the part 12 by the shoulder at the lower end of the recess in the side-stile in which said part 12 is located. Indeed, when the ledges l-4 are provided, some of said weight may be carried thereby, since the diagonal edge 11 of said frame may rest thereon. The frame may be formed in any desired way,-for example, by a casting or by being built up of two or more parts. 16 is a clearance passage in the overhead wall, or surface, 9, through which a sash cord may pass as it hangs down from the inner side of the pulley 6, said end of the sash cord being attached to the window sash (not shown) in the usual manner.

What I claim is:

In an overhead pulley construction, a frame including two exposed right angular portions both arranged to overlap the exposed inside surfaces of a Window casing at screw passage in each of said right angular corner thereof, a pulley housing extending portions. diagonally upward therefrom, a pulley pivotally mounted in said diagonally ex- HENRY VOIGHT tending housing, said right angular por- Witnesses:
