UNITED STATES PATENT OFFICE.
WEIGHLLESS SASH SUPPORT.
Application filed May 28,
supportfthat is to say, a device the function of which is to support an unbalanced sash at any point to which it may be raised in the window casement. The general object of the invention is to produce a device of this kind which is simple in construction and which can be readily applied in practice; also to construct the device so that it can be readily adjusted at will without the necessity of a removal of the sash or any other parts of the window. Further objects of the invention will appear hereinafter.
The invention consists in the novel parts and combination of parts to be described hereinafter, all of which contribute to produce an efficient weightless sash support.
A preferred embodiment of the invention is described in the. following specification,
while the broad scope of the invention is pointed out in the appended claims.
In the drawing:
Figure 1 is a front elevation showing a window casement and a sash to which my invention is applied, the sash being broken away and shown partially in section.
Figure 2 is a front elevation of the device removed from the sash.
Figure 3 is a vertical section taken through the device on the line 3--3 of Figure 2.
In practicing my invention, I provide a stile of the sash with a recess in which I mount a friction device, and I provide adjustingmeans for adjusting the device which passes transversely through the stile so that the outer end of the adjusting device is exposed on the side face of the stile where it is accessible for adjustment.
The friction device preferably comprises in its construction an elongated rigid bar 1 which is received in a recess 2 formed in one of the stiles 3 of the sash 4., This bar is provided at its end with feet 5 which may be countersunk into the face of the stile and provided with holes 6 to receive fastening screws 7. The clamping member is in the form of a resilient bar or leaf spring 8, the ends of which are constructed to press yieldingly against the face 9 of the casement 10.1
1923. Serial m. 641,891.
In the present instance, this yielding effect is attained by making the bar 8 of resilient material and each end of the bar is formed into a head 11 which may carry a contact roller 12 for rolling on the face 9 of the csement when the sash is raised or lowered.
I provide a fulcrum toward each end of the bar, preferably in the form of abutments which project into the recess 2 and which press against the bar 8 at points lo cated toward or near the heads 11. These abutments are preferably formed as offsets 13in the material of the rigid bar 1 and the inner sides of the offset-s 13; that is to say, the sides or portions toward the middle of the bar, are provided with beveled faces 14 for a purpose which will be described hereinafter. Between the abutments the adj usting means is located, and this preferably consists of a threaded member or screw 15 which has an. inner head 16 which passes through the spring bar 8, but which is nonrotatable therein. The outer portion of the adjusting device is in the form of a sleeve 17 having a head 18 at its outer end, and this sleeve operates as a nut on the screw 15. The axis of this adjusting device extends in the planeof the sash and is disposed substantially horizontally so thatthe adjusting head 18 is exposed on the side face 19 of the sash just in front of the window-pane 20 (see Fig. 1).
With this organization of parts, it will be evident that by means of a screw-driver the sleeve 17 may be rotated so as to move the middle portion of the bar 8 laterally in either direction and evidently by tightening the device the amount of how of the bar can be increased, thereby increasing the pressure of the heads 11 (or their rollers) against the face of the casement.
The beveled faces 14 are employed because in this way I avoid rocking the bar on a sharp edge which would increase the tendency to break the bar.
It will be evident that this device can be readily adjusted so as to exert just the required amount of frictional force to support the sash without giving unnecessary resistance to raising it.
Furthermore, the necessary adjustment can be made without necessitating the removal of the window-stops 21 or any other part of the window or sash.
The screw 15 is in the form of a carriage bolt, the square shank of which fits in a square opening 22, in the bar. See Fig. 2. Under the head 18 a washer 23 is placed (see Fig. 3).
It is understood that the embodiment of the invention described herein is only one of the many embodiments this invention may take and I do not wish to be limited in the practice of my invention, nor in my claims to the particular embodiment set forth.
hat I claim is 1. In a device of the kinddescribed, the combination of a bar with means for mounting the same in the stile of the sash, said bar having means for yieldingly engaging the face of the window casement, a fulcrum for the bar located toward each end, and means for adjusting the bar laterally between the fulcrums to regulate the pressure exerted upon the casement.
2. In a device of the kind described, the combination of a sash having a stile with a recess therein, a resilient bar extending longitudinally within the recess and having heads atthe ends thereof for exertingpressure against the face of the easement, abutments projecting into the recess for engaging the outer face of the bar at points disposed respectively toward each head, and means between said abutments for adjusting the bar laterally to regulate the pressure of the heads against the easement.
3. In a device of the kind described, the combination of a sash having a stile with a longitudinal recess therein, a framebar seated in said recess and having an abutment disposed toward each end thereof respectively, a resilientbar-seating against said abutments and having heads beyond the abutments for engaging the casement, and means connecting the resilient barand the frame-bar at a point between the abutments for adjusting the resilient bar to regulate the pressure exerted by the heads.
4. Iniadevice of the kind described, the combination of asash having a stile with a recess therein, a friction device held within the recess, and an adjusting screw connected with the friction device and passing transversely through the stile, the outer end of the adjusting device being exposed on the side face of the stile to permit adjustment thereof.
5. In a device of the kind described, the combination of a sash having a stile with a longitudinal recess therein, a frame-bar seated in said recess and having an abutment disposed toward each end thereof re spectively, a resilient bar seating against said abutments and having heads beyond the abutments for engaging the easement, a threaded member connected with the resilient bar between the abutments and eXtend ing substantially horizontally through the sash substantially in the plane of the sash, and a manually operated threaded member mounted to swivel in the stile and operating as a nut on the first-named threaded member and having its head exposed on the side face of the stile to' enable the same to be adjusted.
