SASH-LOCK.
Specification of Letters Patent.
Patented July 14, 1914.
Application filed April 29, 1913. Serial No. 764,298.
To all whom it may concern Be it known that I, lVILLIAM H. VANCE, a citizen of the United States of America, and residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Sash-Locks, of which the following is aspecification, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates to window locks, particularly of the vertically movable sash type, and the main ob'ect thereof is to provide a lock which will positively prevent the further opening of either sash, when and which will prevent sash operation when both sashes are closed.-
A further object is to provide such a lock which is automatic in operation and which may be secured in its lockedposition so that it cannot be affected by an instrument from the exterior of the window, but which when desired, be thrown entirely out of operative position and out of the way; and a further object is to provide such a lock which will not injure'the woodwork under normal conditions, which is very inexpensive and ornamental, and\ which is well adapted for the purpose for which it is designed.
My invention is fully set forth in the following specification, of which the accompanying drawings form a part, in which the separate parts are designated by the same reference characters in each of the views, and in which s- Figure 1 is a perspective view of my invention applied to a window and'in locked position; and Fig. 2 is a side view thereof, partially in section, in locking position in full lines and in released position in dotted lines, the tampering preventive means bein in inoperative position whereby the dotted position may be attained.
In the drawings forming a part of this application I have shown an upper sash a and a lower sash (l vertically movable in a frame a my sash lock being screwed or otherwise secured to the top of the lower sash, as clearly shown. and it consists of a base I) through which the screws pass and provided with two uprights 7) between which the base is cut away. as clearly shown in Fig. 2, and pivotull v secured to the inner end-of the baseis a" revolving camJ/F having a liba ndle Z) and being cut, away as shown at Pivotally held between the uprights b, by means of a pin, bolt, rivet, or the like 0 1s a dog 0 having an inner tail piece 0 and an enlarged head 0 the outer face of which is toothed as shown at 0 said teeth being preferably formed in two distinct Web memhere, and I also provide a plate 0 of rubber,
' fiber, or other relatively soft material which is inlaid in the face of the dog transversely thereof in such manner as to impinge directly upon the upper sash and prevent the teeth from touching the same under normal conditions, and the face of the head 0 is cam shaped or, as shown, segmental but eccentric to the pivot 0 whereby it binds more and more securely as pressure is applied to open either sash, the upper downwardly, and the lower upwardly, and serving also to mounted in to bind in the runs of theframe.
Normally the dog is thrown backwardly, as indicated by dotted lines in Fi 2, the cam o being turned at this time to %a cut away portion thereof directly in the path of the tail piece 0 so as not to intercept the same in the movement of the dog from operative to inoperative positions but, when it is desired to lock the sashes, either in open or closed positions, the dog is revolved upon its pivot and, through gravity, the head thereof impinges directly upon the inner face of the upper sash, the rubber insert c resting against the same, and, if any attempt be made to raise the lower sash or to lower the upper sash, the cam face of the dog immediately binds against the upper sash and prevents the sash movement, but the upper sash may be moved upwardly and the lower sash downwardly without any effect upon the look.
force the sashes apart if loosely the frame and cause the same ve the the upper sash and the teeth are forced into the sash to positivelyresist such attempt to open the window.
It will therefore be seen that I provide an automatic, burglar-proof, lock which is easily placed in position by any person who can use a screw-driver, which ma be secured against manipulation over t e automatic operation, which may be placed at either the right or left side of the Window, and Which is very inexpensive.
Having fully set forth my invention, Wha I claim as new, and desire to secure by Letters Patent, is
A sash lock, comprising a base adapted to be secured to the top of the lowersash,
uprights thereon, a dog pivoted to said up rights and having a cam face impinging on i the upper sash and provided With a tail. piece and a cam arranged beneath said tail piece to prevent the operation of said dog in one position but being cut away at one point to permit moving said dog 'into inoperative position.
In testimony thatI claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 22d day of April 1913.
