SASH-LOCK.
SPECIFICATION forming part of Letters Patent No. 767,677, dated August 16, 1904.
Application filed January 23, 1904. Serial No. 190,264. (No model.)
possible to effect an entrance from the outside without destroying the sash or the glass.
With this object in view the invention may be said to consist in the novel construction, arrangement, and combination of parts hereinafter described, and more particularly pointed out in the claims.
In the accompanying drawings, which illustrate the invention, Figure 1 shows a vertical central section of my improved lock applied to the meeting-rails of the window-sashes. Fig. 2 is a plan view of the lock. Fig. 3 is a plan view of the same with the lever and the cap forming part of the invention removed.
Fig. 4 is an inverted plan view of the cap. Fig. 5 is a detail perspective view of a segmental cam forming part of the invention.
In said drawings, Idesignates the meetingrail of the lower sash, and 2 designates the meeting-rail of the upper sash, which latter is provided with a keeper 3, provided with a rectangular loop4 and flanges 5 and 6, arranged substantially at right angles to fit the'top and face of meeting-rail 2, to which they are rigidly secured by screws 7.
8 designates the locking device, which consists of a segmental casing 9 open at its rear portion to receive loop 1 and formed integral with a rectangular base 10, which is rigidly secured to the top of the meeting-rail 1 by screws 11.
15 designates a segmental cam arranged to turn in groove 13 and provided near one end with a rigidly-secured vertical pin 16, which extends upwardly through a segmental slot 17 in a cap 18 and engages a cam-lever 19, fulcrumed upon a screw 20, which extends downwardly through the cap and engages a centrally-threaded aperture 21 in hub 12.
Screw is provided with a shoulder 22, which engages the upper surface of the cap, and thus prevents the screw from being adjusted downwardly far enough to cause its head 23 to bind against the cam-lever and prevent the latter from turning on the screw. Slot 24:, whereby the lever is pivotally secured to screw 20, is slightly elongated to permit the outer end of the lever to swing up and down, as indicated by the arrow in Fig. l, in order that its lip 25 may engage and disengage either one of oppositely-disposed notches 26 in the underside of a marginal flange 27,formed integral with the under side of the cap to assist in holding the latter on top of casing 9.
One end of cam 15 is made tapering, as at 15, to facilitate its entrance into loop 4:, and when the cam is turned to the position shown in Figs. 1 and 3 it will engage the front and upper interior walls of the loop, and thus draw the sashes tightly together, as above described. hen in this position, the cam and the lever will be reliably held from turning by lip 25 engaging one of notches 26. The cam is likewise held in an open position for the admission of the loop by lip 25 engaging the oppositely-disposed notch 26. Thus it will be understood that the lever is held from accidental movement when in either position.
From the above description it is apparent that I have produced a substantial sash-lock which is simple in construction and operation and thoroughly effective for the purpose intended.
While 1 have shown and described the preferred form of my device, I reserve the right to make such changes as properly fall within a concentric hub formed integral with the base of less diameter than the casing to leave an intervening groove, a segmental cam slidingly arranged in the groove and provided With a tapering end, a pin projecting u pwa'rdly from the cam near its opposite end, a lever fulcrumed to the hub and provided with a counterbore for the reception of the pin, and a keeper adapted to be engaged by the cam.
' 2. A sash-lock consisting of a base portion, a segmental casing formed integral therewith, and open at its rear side, a concentric hub formed integral with the base of less diameter than the casing to leave an intervening groove, a segmental cam slidingly arranged in the groove, a pin projecting upwardly from said cam, a cap for closing the top of the casing provided with a segmental slot to receive the pin on the cam and provided with a marginal recess which registers with the open side of the casing, a lever fulcrumed to the hub and provided with a counterbore for the reception of the pin on the cam, and a keeper adapted to be engaged and disengaged by the cam.
3. A sash-lock consisting of a base portion, a segmental casing formed integral therewith, aconcentric hub formed integral with the base of less diameter than the casing to leave an intervening groove, asegmental cam slidingly arranged in the groove, an upwardly-projecting pin secured to the cam near one of its ends, a cap for closing the top of the casing provided with a segmental slot for the reception of the pin, a depending marginal flange formed integral with the cap and provided with diametrically opposite notches, a post extending upwardly from the central portion of the hub, a lever loosely secured thereto and provided with a counterbore to receive the pin on the cam, a lip on the lever adapted to engage either of the notches on the cap, means for yieldingly holding said lip in the notches, and a keeper adapted to be engaged and disengaged by the cam.
In testimony whereof I afiix my signature in the presence of two witnesses.
