THOMAS RICHARDS, OF CI-IICA GO, ILLINOIS.
SASH-LOCK.
Specification'of Letters Patent.
Patented Aug. 3, 1915.
Application filed. May 21, 1915. Serial No. 29,499.
\ T all whom it may concern by the plate is securely Be it known that I, Tnoams RICHARDS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sash-Locks, of which the following is a'specificatiou;
This invention relates to devices for look: ing windowsashes, and more particularlya device of this kind which is applied to the meeting rails for locking the sashes when they are closed.
The invention has for its object to provide a simple and efficient sash lock of the kind stated, the same being characterized by a novel and improved sliding bolt and a geeper therefor, and means for operating the olt.
In order that the invention may be better understood reference is had to the accompanying drawing in which Figure 1 is a plan view of the device showing its application; Fig. 2 is a cross-section on the line 22 of Fig. 1, and Fig. 3 is a face view of the keeper portion of the device.
In the drawing, 5 and 6, respectively, denote the meeting rails of two sliding window sashes. The meeting rail 5 carries the sliding'bolt of the device, and the meeting rail (3 carries a keeper for said bolt.
The sliding bolt is denoted by the refer ence character 7', the same being mounted on a base plate 8 suitably secured to the rail 5, on top thereof, and having an undercut transverse groove 9 in which the bolt slidably seats, the latter being shaped to fit the groove. The bolt is operated by a lever 10 pivoted at 11 to the base plate, and having adjacent to the pivot a connection with the bolt, said connection being made by means of an upstanding pin or stud 12 on the bolt extending into an aperture 13 in the lever, said aperture being large enough to allow for the arcuate path thereof when the lever is swung to advance or retract the bolt.
The keeper for thebolt 7 is an aperture 14 the front edge of a plate 15 secured on top of the rail 6 and having a depending ront flange 16 which is set flush in the face of the rail and secured by screws 17, wherefastened tothe rail insuch a manner that it cannot work loose or be pried off. The top of the plate has a raised portion 18 in which the keeper aperture is made. This raised portion is widest midway between its ends and it tapers toward each end, so that its rear edge forms a cam surface 19. The free end of the lever 10 is shaped to ride over the top of the raised portion 18 and has a depending portion 20 designed to ride along the cam surface 19. The raised portion alsp slopes down at the ends from the top to form inclines.
Upon swinging the lever 10 over to the keeper plate 15, the bolt 7 is advanced into the keeper aperture 14, whereby the sashes are securely locked together. The lever is swung over far enough to extend across the keeper plate, and when it rides up the inclined end of the raised portion 18 it is tightly wedged. produced between the cam surface 19 and the part 20 of the lever. The lever is therefore firmly held, and the sashes are also drawn tightly together and prevented from rattling. The bottom edge of that portion of the lever which engages the top of the part 18 is slightly inclined to increase the wedging action. Upon swinging the lever back over the rail 5'the bolt is withdrawn and the sashes are now unlocked and left free to be opened.
I claim 1. A sash lock comprising a base plate, a sliding bolt carried by the base plate, a le- A wedging action is also ver pivoted to the base plate and having an operative connection with the bolt, and a keeper plate having an aperture to receive the forward end of the bolt when the same is advanced and a raised portion across which the lever extends after it is swung to advance the bolt into the aperture, the back edge'of the raised portion being cam shaped, and the free end of the lever having a de pending part adapted to wedge against said cam shaped edge.
2. A sash lock comprisinga base plate, a sliding bolt carried by the base plate, a lever pivoted to the base plate and having an operative connection with the'bolt, and a keeper plate having an aperture to receive the bolt and a raised portion across which the lever rides upward when it is swung to advance the bolt, the back edge of the raised portion being cam shaped, and the free end of the lever having a dependingpart adapted to Wedge against said cam shaped edge.
