PULLEY-MOUNTING.

Specification of Letters Patent.

Patented Jan. 9, 1906.

To all whom it may concern.-

Be it known that we, WILLIAM T. MODER- MOTT and WILLIAM F. BETZEL, citizens of the United States, residing at Baltimore, in the State of Maryland, have invented a new and useful Pulley-Mounting, of which the following is a specification.

The present invention relates to means for mounting pulleys in window or analogous frames, and particularly that type of windowframeconstructed of sheet metal, though perhaps useful in other structures.

One of the objects is to provide a simple mounting of a novel nature that can be easily placed and securely fastened in position and at the same time will permit the ready removal and replacement of the pulley should it become necessary to do so onaccount of such pulley becoming worn, deranged, or clefective from any cause.

A further and important object is to provide a mounting that will rigidly maintain its position to effectually withstand the strains to which such structures are necessarily subjected and will, furthermore, reinforce the frame-wall to which it is applied so as to avoid any danger of the wall becoming warped or misshapen.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein- Figure 1 is a view in front elevation of a portion of a window-frame, showing the new pulley-mounting in place thereon. Fig. 2 is a rear elevation of the same. Fig. 3 is a longitudinal sectional view taken on the line 3 3 of Fig. 1. Fig. 4 is across-sectional view taken on the line 4 4. of Fig. 1. Fig. 5 is another cross-sectional View taken on the line 5 5 of Fig. 1. Fig. 6 is adetail perspective view of 'the retaining-plate, and Fig. 7 is a similar view of the pulley-supporting member.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated a portion of the inner wall of the side stile of a metallic window-frame is shown and is designated by the reference-numeral 8. The wall is provided with a sash-guideway 9, formed between two beads 10. This wall is provided between the beads with a longitudinally-disposed opening, surrounded by rearwardly extending flanges 11. The mounting for the sash-cord pulley is located at this point and is constructed as follows: A retaining-plate 12 is employed that is secured against the rear face of the wall 8 by means of holding-screws 13 passing through said wall above and below the opening therein and being threaded into the ends of the plate. In this connection it is desired to call attention to the fact that the heads 14 of saidscrews are countersunk into the side and end walls of the seat. An opening 17 in the plate 12 communicates with the seat and is of less width than the same, so that flanges 18 are formed on opposite sides of said opening. In the rear face of the retainingplate is formed a seat 19, located at one end of the opening 17. The pulley-supporting member consists of a face-plate 20, carrying a pulley-boxing21. This plate 20 is arranged to fit snugly in the seat 16 and within the flanges 11, so that its outer face is flush with the outer face of the frame-wall, as shown in Figs. 3 and 4.. This plate has at one end an inset longitudinally-extending tongue 22, that is adapted to pass through the opening 17 and engage in the seat 19, while through the op-, posite exposed end of the face-plate is passed a holding-screw 23, that is threaded into the retainingplate 12. The boxing 21 is narrower than the plate 20 and is adapted to pass through the opening 17, while the sides of said plate on opposite sides of the boxing rest against the flanges 18. In said boxing is journaled a suitable sash-cord pulley 24:, that extends through an opening 25, formed in the face-plate. The retaining-plate can be secured to the inner side of the wall 8 during the manufacture of the window-frame; but the pulley-supporting member can be placed in position at any time. as it is only necessary to pass the tongue 22 through the opening 17, at the same time introducing the boxing 21 into said opening, then seating the plate 20 in the recess 16 and fastening it in place by means of the screw 23. It will be clearly apparent, therefore, that the pulley can be detached and replaced with ease and expedition. Moreover, it will be apparent that this mounting serves as a reinforcement to the frame at the place where the combined weight of the sash and counterbalance is carried, and thus the danger of the frame becoming distorted from such weight is obviated. Furthermore, because of the interfitting engagement of the flanges 11 and the portions 15 of the wall with the mounting said mounting is effectually retained in position.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a pulley-mounting, the combination with a retaining-plate to be secured to a window-frame or analogous support, said plate having an opening, of a pulley-support having portions that engage both the inner and outer sides of the plate, a part of the support extending through the opening and said support being removable outwardly through said opening, a pulley journaled on the support, and means on the outside of the plate for detachably securing the support against movement to the retaining-plate, said securing means thus being accessible when the plate is secured to a window-frame to permit the removal of the pulley-support and the pulley carried thereby.

2. In a pulley-mounting, the combination with a retaining-plate to be secured to awindow-frame or analogus support and having an opening, of a pulley-boxing fitting in the opening and having a face-plate that engages both the inner and outer sides of the retaining-plate, said boxing being removable outwardly through the opening a pulley journaled in the boxing, means for detachably fastening the boxing to the outer side of the retaining-plate, said means being accessible when the plate is secured to a window-frame to permit the detachment of the boxing and pulley carried thereby and means for fastening the retaining-plate to a support.

3. In a pulley-mounting, the combination with a retaining-plate to be secured to a Window-frame or analogous support, said plate having a seat in its outer face and an opening that communicates with said seat, of a pulleysupport that passes through the opening, said support having a face-plate that fits in the seat, a tongue carried by the face-plate and engaging the rear face of the retaining-plate, means for securing the retaining-plate to a frame or other support, means for detachably securing the face-plate in the seat, and a pulley journaled in the support.

4.
