SASH-CORD PULLEY.

Specification of Letters Patent.

Patented June 11, 1912.

Application filed December 20, 1911. Serial No. 666,898.

To all whom it may concern:

Be it known that I, JAMES H. Foorn, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sash-Cord Pulleys; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and tothe figures and letters of reference marked thereon.

This invention relates to sash cord pulleys of that type adapted to be inserted and seated in the window framing without the signed for use at the upper ends of the stiles of the framing, or in immediate proximity .to the head of the framing, although features of the invention are applicable to pulleys adapted for being located at any point in the side or stile of the window framing.

Referring to the drawings,Figure 1 is V a section in a vertical plane through a sash cord pulley embodying the present improvements mounted in position in a window framing, the latter being also shown in section; Fig. 2 is a section in a horizontal plane indicated by the line 22 of Fig. 1 looking downwardly; Fig. 3 is a detail front'elevation of the upper portion of the pulley; Fig. 4 is a corresponding rear elevation with the pulley mounted in position in the framing; Fig. 5 is asectional view corresponding to Fig. 1, but illustrating a modified form of keeper with a face plate formed as an integral part thereof.

Like letters of reference in the several figures indicate the same parts.

The sheave bearing casing of the pulley forming the present invention is illustrated in the accompanying drawings as an integral casting, but it will be understood that it may be formed of sheet metal by well known processes now in common use. It is provided I with two substantially parallel walls A between which the sheave B is journaled and at top and bottom it is provided with extensions or projections, the top oxtension or projectionbeing indicated by the reference letter (land the bottom extension by the reference letter D. The top extension C may be formed by portions of the side walls A and is provided with a rearwardly directed face 0, while the bottom extension D is provided with a forwardly directed face 0?, these two faces being preferably in substantially the same vertical plane and are adapted to cooperate with faces on the window framing. The face (Z seats against the inner side of the framing F, while the face 0 seats against the rear side of a recess fin the head f of the framing. The top extension is of greater length than the bottom extension D, and consequently the whole sheave bearing casing may be inserted in its opening in the window framing by passing the top extension up into the recess f a suflicient distance to permit the bottom extension D to pass through the slot, whereupon by a bodily downward movement of the casing it will seat itself in the window framing, the bottom extension preventing any outward movement at the lower end, and the top extension preventing any inward movement of the upper end. To hold the casing down to its seated position, the top extension C is provided with a rearwardly extending shoulder or offset a which is adapted to pass under the inner wall of the recess f, as shown clearly in Figs. 1 and 5, if necessary, suflicient force being exerted upon the upper end of the casing to force the projection or projections 0 into the wood of the head of the window framing. The forward or outer side of the extension G is, as shown, preferably in rear of the vertical plane of the front of the sheave bearing casing, whereby the whole extension C, including the shoulder or offset 0, may be passed up into the recess f while the pulley, is being placed inposition, and when the pulley is in position a keeper is inserted in front of the projection or extension C, so as to hold the sheave bearing casing back in its vertical position, with the shoulders or offsets c beneath the rear wall 'of't-herecess. This keeper, as shown in Fig. 1, may consist of a piece of sheet metal H, the front portion of which may lie substantially flush with the frontv of the sheave bearing casing, while a rearwardly extending portion [2, is adapted to bear against the extension C and to be positioned by a shoulder or stop 0 on p the front of the extension. The form of keeper shown in Fig. 1 is adapted to occupy the recess in front of the extension C, but it is obvious that the said keeper might be extended to form a face plate I as indicated in Fig. 5, in which instance it is provided at its lower end with an inwardly extending.

ing is preferably inclined downwardly and forwardly, as at (Z whereby when seated it will prevent anyinward movement of the lower end of the casing, this inclined face also operating in a measure with a tendency to hold the lower portion of the sheave bearing casing out to its proper position with the extension D firmly seated against the inner face of the framing.

At the front each side wall A is provided with a transverse rib orflange a serving to fill the slot or opening in the window framing, and thereby give a good face finish, and it is preferred that these ribs or flanges shall seat slightly in the sidewallsof the slot in the window framing to thereby-not only position the sheave bearing casingcentrally in said slot and form'a tight'fit, but also prevent bodily inward movement of-the sheave bearing casing, whereby any danger of the said casing dropping into the weight box is obviated.

In inserting the sheave bearing casing-in the window framing, the top extension is passed up into the recess f as indicated by dotted lines in Fig. 5, then the lower portion is swung in and'the whole casing allowed to move bodily downward until it seats at the bottom of the slot in the framing, and the upper end is pushed back until the shoulders or offsets 0 pass beneath the inner wall of the recess f thereby holding the device firmly down to its seat. The

keeper is then inserted in front of the top extension C and its lower end swung down into position indicated in full lines in Figs. 1 and 5. Where a short keeper, as shown in Fig. 1, is employed, it is preferably provided with an aperture hthrough which. a suitable instrument may be passed for removing the keeper, should it be necessary at any time to take the pulley out of the window framing.

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

1. A sash cord pulley embodying a sheave bearing casing having an extension at the top adapted to enter a recess in the framing whereby it is held against escape toward front and rear and a projection at the'bottom on the inner side of the casing of less length than the top extension and adapted to seat against the inner side of the framing, whereby the bottom projection may be passed through the framing and seated against the inner side thereof without withdrawing the top extension from its recess, means for preventing the bodily upward movement and for preventing the inward movement of the bottom of the casing when seated in the framing.

2. A sash cord pulley adapted to be seated in the window framing by a bodily downward movement, embodying a sheave bearing casing having an extension at the top adapted to enter a recess in the framing, whereby it is held against escape toward the front and rear, a projection at the bot--' tom on the inner side of less length than the top extension and adapted to seat against the inner side of the framing whereby the bottom projection may be passed through the framing and seated against the inner side thereof without withdrawing the top extension from its recess, a movable keeper supported by the casing in front of and cooperating withthe top extension, and means for preventing bodily upward movementand for preventing the inward movement of the bottom of the casing when seated in the window framing.

8. A sash cord pulley adapted to be seated in the window framin by a bodily downward movement, embo'c ying a sheave'bearing casing having-extensions at the top and bottom, with rearwardly and forwardly directed faces respectivelyin substantiallythe same plane, a shoulder on the top extension projecting 1n rear of said plane for holding the casing down to its seat, means on the casing for limiting its inward movement at the lower end, and a movable keeper cooperating with theouter side of the top projection.

i. A sash cord pulley adapted to-be seated in the window framing'by a bodily downward movement embodying a sheave bearing casing having extensions at the top and a bottom with rearwardly and forwardly di; rected faces respectively in substantially the same plane, the topextensionhaving its for-' wardly directed face in'a plane in rear of the plane of the front of the casing, and a movable keeper located in front of and 00- operating with the top extension.
