SASH-FASTENER.
SPECIFICATION forming part of Letters Patent No. 727,950, dated May 12, 1903. Application filed January 31, 1903. Serial No. 141,247. (No model.)
To all whom it may concern.-
Be it known that I, CHARLES HOWARD HOOK, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Sash-Fasteners, of which the followingis a specification.
My invention relates to improvements in a sash-fastener for windows.
The object of the invention is to provide a device which shall rigidly secure a window from movement either in the direction in which it operates or from a lateral movement.
At the present time in alarge majority of houses considerable annoyance is experienced by rattling windows; and the present inven tion has for one of its objects to provide a device which will rigidly hold the windows to overcome the trouble.
Another object of the invention is to provide a device which will secure the window and prevent the same from being forced open from the exterior. 1
The invention is illustrated in the accompanying drawings, in which- Figure 1 illustrates a front elevation of a portion of a window provided with my improved'fastener. Fig. 2 is a perspective sectional view of same. Fig. 3 is a detail perspective view of the keeper. Fig. 4 is a sectional view on the line 44 of Fig. 1.
In the drawings, a designates the windowsill; b, the frame; a, the sash, and c the glass. The frame maybe provided with the usual strip cl, although this is not essential and may be omitted. Secured to the strip of in the present instance is a stationary keeper 6. This keeper is provided with abottomconstruction will be hereinafter pointed out. Extending lengthwise of the keeper is a projecting wall h, the inner surface h of which is tapered, said wall being thicker at the end k tends in a direction lengthwise of and just above the concave surface g.
Secured to the sash cis a locking device which coacts with the stationary keeper. This locking device comprises a circular head j, having a flat circumferential surfacej and an operating-arm The circular head of this locking device is provided on each side with a boss It and k, which project laterally and have an eccentric position with respect to the said head. A screw 1 passes through each of saidbosses and also through said head and pivots the head eccentrically to the sash c. A The head j is. also. provided on one side with a'oam-surface m, which in the present instance has position on said head dia- This tapered surface, it will be seen, GX-I tact with said sash, while the rim edge 1; will be set away from said sash. The advantage in this is apparent, for it reduces the frictionsurface against the sash and prevents the sash from being scratched in a conspicuous place.
When the locking device is in place on the sash and the keeper has been properly placed 'on the frame, the circumferential surface j of the head when the latter is turned eccentrically will engage the concave surface 9 on the keeper, and at the same time the cam m on the said head will impinge against the tajpered surface it of the keeper and push the window outwardly. It is obvious, therefore, that in order to rigidly secure the window the head must be turned eccentrically as far as it will go.
It has heretofore. been explained that the lowest portion gof the concave surface is nearer one 'end of the keeper than to the other. The advantage in this construction will now be explained, reference being had more particularly to Fig. 1. In said figure it will be seen that the broken line g represents the concave surface and that said surface projects farther around and over the top of the circumferential surfacej of the head than it does at the bottom. The advantage in this is that a greater surface is presented by the keeper to the head to resist the forcing of the window from the outside.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a window-sash fastener the combination of an eccentrically-pivoted head having a circular circumferential surface and also having a boss which projects beyond the rim contacts with the circumferential surface of said head.
2. In a window-sash fastener the combination of an eccentrically-pivoted head having a circular circumferential surface and a camsurface on its side, and a keeper having a concave surface which latter is higher at one end than at the other and receives the circumferential surface of said head, said keeper also having an incline side surface, and the broader end of said side surface being at the higher end of the concave surface.
In testimony whereof I affix my signature in the presence of two witnesses.
CHARLES HOWARD HOOK.
