SPECIFICATION forming pari; of Letters Patent No. 362,714, dated May 10, 1887.

Application filed August 16, 1886. Serial No. 210,972.

To all whom t may concern:

Be it known that I, SILAs S. BRADSHAW, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in 'indows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part ofthis specification.

This invention has for its object to provide an improvement in window-sash mountings in which the sash is provided with separate pieces upon its vertical edges that run in the stilegrooves, and from which the sash can be entirely detached at pleasure for the purpose of cleaning the window or for other purposes.

To this end the invention consists in the matters hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, which illustrate one practicable and desirable form in which my invention may be embodied, Figure lis an elevation of a window-frame containing sliding sash having my improvement applied thereto. Fig. 2 is a transverse vertical section in the linew of Fig. l. Fig. 3 is a horizontal fragmentary section in the line e z of Figrl. Fig. 4 is a horizontal fragmentary section on the line yy of Figs. l and 2. Fig. 5 is a vertical fragmentary section of a sash in the line y y of Fig. G. Fig. 6 is a horizontal section iu the line a' m of Fig. 5, showing one sash present and the other removed.

A A is a window-frame, of which B B are the pulley-Stiles and C C are the stops, between which are the grooves O, for guiding the sash in their vertical movements.

D is the inner or lower and D is the outer or upper sash guided by the grooves C.

E E are slides iitted to the grooves O,and respectively secured detachably to the vertical margins of the sash l) D.

F F are the sash-cords connected with the slides E E', and G G are sash-weights.

A distinctive novelty of my improvement consists in securing the sash to the marginal slides E L in such manner that they are wholly detachable therefrom, so that the sash may be entirely removed from the window-frame, and, for example, taken to another place to be (No model.)

cleaned, or laid entirely aside and out of the way, if itbe desired to` open the entire windowspace to the passage of air. This novel feature involves several matters of construction as either needful or desirable, and which are shown and described inthe forms now believed to be best, but which may be changed without departure from my principal invention. For example, when a sash is entirely removed from its slides, in a lowered position, it is desirable that the latter shall not be allowed to run violently to the top of the frame under the action of the weights attached thereto, and I have therefore provided a catch which may engage each of the slides to the adjacent stile, and thus hold it down. l

I have also provided means for retaining the slides in their grooves when the window-sash is removed as a desirable end to be attained, and I have shown the connections of a sash with its slides such that the sash may be only tilted, if desired, without, or preliminary to, complete removal. I have also sought to simplity the operation ot' working the invention by showing such a construction of the catch for holding the slides down that said catch will automatically engage the stile upon the removal of the sash, and will be detached from the stile automatically upon the insertion of the sash. I of course do not wish to be restricted te the employment of these and other auxiliary devices, or to the particular forms of such devices as are shown.

The slides E E and sash D D/ are shown as rabbeted on their contiguous faces to provide a shoulder or stop at c, against which the sash may bear outwardly against the slide. As a desirable construction the slides lfor the upper sash are shown thicker than the slides E, and having thinner parts (produced by the rabbet) as thick or thicker than the thicker part of the lower slides, E, whereby the upper sash, when lowered to the bottom of the window-frame, may be drawn inward between the slides ofthe lower sash, from which slides said lower sash shall have been previously removed.

At or near the lower end of each of the several slides E E is provided a short fixed pin, e, and the sash is provided with adownwardlydirected open slot or recess, d, to receive said pin, which construction permits the sash to be IOO raised entirely clear of the slides. AtA some elevated part of the sash suitable catches arek provided for engaging the sash with the slides-as, for example, a iiush ring-bolt, as shown at d', Fig. l, or a mortise spring-bolt, as shown at d', Fig. 5. These serve to hold the sash upright and secure the upper part of the sash, while the pins e secure the lower part to the slides.

I prefer to make the shoulder e undercut, as shown on both the sash and slides, so that when the sash is forced to proper alignment with the slides the latter will be held close to the sash.

As one of many suitable forms of catch by which to holdethe slides down after the sash has been withdrawn, a simple sliding bolt may be employed, fastened either to the frame or to the slide and entering the other when thrown; or a hook pivoted on the slide may be arranged to engageascrew head or pin on the stile, like a familiar form of window-fastening. These and other equivalent catches are so common and Well known as not to require illustration. I prefer, however, to use a catch that shall be thrown into action or allowed to act by the outward movement of the sash, andthat shall be disengaged by the insertion ot' the sash. A practical form of such a device is shown in detail in Figs. 5 and 6.

His a bent lever pivoted between its ends to the top of the slide, the end h thereof having a throw into and ont of a recess, b, in the stile B. The opposite end, h', is made curved and convex, and is arranged to project into the path of the sash or beyond the adjacent vertical face of the slide, as shown. Any suitable form of springs-as, for example, a bent platespring, -is applied to the lever H, so as to normally throw said lever into position to enterthe recess b in the stile and thereby lock the slide to the stile. When the sash is inserted, it'pushes the end h of the lever H inward and withdraws its opposite end from the stile; but when the sash is removed it allows the lever to swing on its pivot under the action of the spring to engage the stile, and the locking and release of the slide are thus made, respectively,simultaneous with the removal or insertion of the sash.

As this device is here shown, the lever II and its spring are housed in a metal case, H, having a vertical plate, h3, Fig. 5, by which the housing may be better secured to the slide,

and which may also afford aseat or striker for a bolt, d. Metal plates D2 are also shown as being attached to the upper corners of the sash 'to act as strikersfor the lever I-I, both the housing I-I and the striker D2 being undercut at the shoulder e. It desired, the catch for holding the slides down may be located at their lower instead of their upper ends, or between their ends.

To retain the slides in the grooves C the slides may be provided with projections occupying grooves in or applied to the stops. In the drawings, external devices for this purpose are shown in Figs. 2, 3, 4, and 6, I I being plates, fastened to the stops C, and provided with lips f,affording grooves i', and J being angleplates having projecting tongues or lips j, which occupy the grooves t" when the sash is in position to permit its removal from the slides. Provision is made for withdrawing the sashes in their lowered positions, as shown in Fig. 6, the sash being released first at its upper end, then tilted inward on the pins e', as also there shown, and then lifted oft said pins and carried away. To reinsert the sash this operation is simply reversed, the sash being dropped down over the pins e', then pnshed'into an upright position between the slides,and fastened by such devices as may bey employed for the purpose. Y

My invention contemplates the entire detachment of the sashes fromthe slides, while the latter are held upright in the lower part of the window-frame in position to again con'- venientl y receive the sashes when the latter are ready to be replaced. My improvementtherefore allows of the entire removal ofthe sashes from the window to permit them to be taken4 to a proper place for cleaning, and also allows of their removal and replacement by the operator without climbing or leaving the door. The catches for securing the slides to the stile are, however, not limited in their use to the construction in which the slides are wholly detachable from the sash; but they lmay be employed in connection with the olderpivoted or hinged construction in which the sashes are merely movable with respect to the slides and are not entirely detachable therefrom.

In a subsequentlyled application for patent-namely, No. 220,757, filed December 6, 1886--relating to the same general subject, matters are shown which fall within some of the claims of this patent; but such matters are not here specifically claimed.

I claim as my invention-H 1. The combination of a grooved windowframe, slides l`fitted to run in the grooves of said frame, a sash wholly detachable from said slides, sash-weights attached to the slides, fast enings which detachably secure the sash to the slides, and other fastenings on the several slides which detachably engage said slides with the window-frame.

2. The combination, with a window-frame and a vertically-movable sash, of weighted window-slides at the vertical margins of the sash fitted to run in engagement with the framestiles, means for detachably securing the sash to the slides,whereby the sash may be entirely removed from the slides while the latter are retained in the frame, and movable fastenings on the slides for retaining the latter in place at the lower part of the window-frame when the sash is being removed and when absent.
