J. JACOB DUPLEX TAMPERPROOF SASH LOCK Filed May 27, 1936 Fqy- 2 Sheets-Sheet2 Patented Apr. 27, 1937 PATENT FFiE DUPLEX TAMPERPROOF SASH LOCK John Jacob, New York, N. Y.
Application May 27, 1936, Serial No. 82,105
2 Claims.
My invention relates to sash locks and it consists in the constructions, arrangements and combinations herein described and claimed.
It is an object of the invention to provide a dual sash lock in which the upper and lower sashes of double hung windows may be effectively locked in various adjusted positions.
It is also an object of the invention to provide a lock wherein either of the windows may be individually locked in an open position, yet being of such nature that the lock may not be forcibly opened.
It is a still further object of the invention to provide a sash lock which may be readily incorporated upon old and new window structures at a minimum of cost.
Additional objects, advantages and features of invention will be apparent from the following description and accompanying drawings, wherein Figure 1 is a fragmentary perspective view of a window having my lock installed thereon.
Figure 2 is a fragmentary vertical sectional v1ew.
Figure 3 is a similar view taken at right angles to Figure 2.
Figure 4 is a horizontal cross sectional view.
Figure 5 is a perspective view of a combined mounting plate and bolt actuator.
Figure 6 is a perspective view of the locking bolt.
There is illustrated generally, a window In including upper and lower sliding sashes II and I2.
Upon the lower sash l2 there is a plate I3, one end M of which is bent at right angles to snugly rest upon the upper face of the horizontal stile [5, while the end [B of the plate lies flush against the front face of the vertical stile H. The portion M of the plate is suitably drilled for fastening means, as will be presently described, and the portion l6 includes a staple l8 cooperable with a locking bolt, generally indicated at l9.
A mounting plate 20, of angular formation is provided, one leg 2| of which is to be positioned upon the portion M, the other leg 22 abutting the portion [6. The leg 2| has apertures 23 adapted to register with apertures of the portion M for receiving mounting screws 24. The plates l3 and 20 are thus rigidly secured to the lower sash.
A guide plate 25 is rigidly connected with the leg 22, extending at right angles thereto, being of arcuate shape, in the body of which there is formed a slot 26. The slot 26 extends longitudinally of the plate, but at an angle, the innermost point of the slot being quite close to the leg 22, and extends at an angle outwardly therefrom.
The mounting plate 20, as may be seen from Figures 1 and 5, includes an integrally connected sleeve 21, along one longitudinal edge of the leg 2| the sleeve being of a length slightly less than the length of the leg.
The bolt l9 comprises locking pins 28 and 29, disposed at right angles to each other and integrally connected with a rod 30. The pin 28 is reciprocable through the sleeve 21 and retractable by a helical spring 3| interposed between the sleeve 21 and a Washer 32 positioned upon the pin 28 adjacent the juncture of the pin with the rod 38. The rod 30 passes through the slot 26, and in operation the rod 30 will traverse the slot for the purpose of disengaging the pin 28 from the apertured strike plate 33 of the upper sash H.
The rod 30 is connected to the pin 29 intermediate its length, one portion 34 thereof adapted to engage in an aperture 35 of a strike plate 36 suitably mounted upon the frame of the window, the other portion 31 swingably mounting a hasp 3B, cooperable with the staple [8.
With the device applied to a window, and it be desired to lower and lock the upper sash II at a predetermined open position, assuming the parts to be in the position shown in Figure l, the hasp 38 is swung upwardly so as to clear the staple l8, and the locking bolt I9 swung upwardly, as shown in dotted lines in Figure 2, the locking pin 28 serving as the pivot. During such movement it will be seen that the rod 20 will follow the slot 36 causing retraction of the bolt 28 from engagement with the strike plate 33. In such position of the parts the upper sash may be lowered to the point desired which must of course bring an aperture of the plate 33 into alinement with the pin 28. The bolt I9 is then swung back to the position shown in Figure l, causing movement of the pin 28 into an aperture of the strike plate 33, against the action of the spring 3|, and the pin 34 will also be engaged in an aperture of the strike plate 36. The hasp 38 is next moved into position over the staple [8. Any suitable padlock may of course be associated with the staple for preventing unauthorized opening of the sash lock.
It will be understood of course that both of the sashes II and I2 may be moved to a desired position of adjustment and then locked, the only requirement in any event, is that the locking pins shall register with an aperture of respective strike plates.
The apertures of the strike plates may have any shape desired so as to permit engagement of the locking pins, and also the spacing of the apertures may vary according to particular needs.
The strike plates may be mounted in suitable channels 39 formed in the frame work, anchored by means of spaced lugs 40, suitably apertured to receive screws 4|.
While I have shown and described a preferred form of my sash lock, this is for the purpose of illustration only, and I consider as my own, all such modifications as fairly fall within the scope of the appended claims.
I claim:
1. A duplex sash lock comprising a mounting plate adapted to be mounted upon the upper stile of the lower sash of a window, said mounting plate including a sleeve, a locking pin revolubly and reciprocably mounted in the sleeve and adapted to cooperate with the apertures of a strike plate on the upper sash, a rod integrally connected with the pin, said rod extending in a plane parallel with the vertical stile of the lower sash, and terminating in a right angularly disposed locking pin adapted to cooperate with an apertured strike plate mounted on the window frame, and camming means engageable with said tract the locking pin, a rod connected with the pin and extended substantially at right angles thereto and lying in a plane parallel to the vertical axis of the lower sash and terminating in a right angularly disposed arm, one end portion of the arm having a hasp thereon, the other end of the arm defining a locking pin adapted to cooperate with an apertured strike plate mounted on the frame of the window and cooperable with the last named locking pin, a staple member carried by the lower sash member and cooperable with the hasp, and an upwardly curved plate integrally connected with the mounting plate, said plate having a slot inclined at an angle from the base of the plate toward its upper outer edge and receiving said rod therethrough.
JOHN JACOB.
