GEORGE M. BLANDFORD, OF BOSTON, IIIASSACHUSETTS, ASSIGNOR TO BATES & BLAND- FORD, OF BOSTON, MASSACHUSETTS, A FIRM.
SASH-LOCK.
To all whom it may concern:
Be it known that I, GEORGE M. Briannronn, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Sash-Locks, of which the following is a specification.
This invention relates to sash-locks, and has for its object to construct a lock adapted to be applied to one of the uprights of the upper sash and which may be extended over the top of the lower sash, to limit upward movement of the lower sash and also downward movement of the upper sash, and furthermore, which may be moved into outofuse position so as to permit unobstructed movement of both sashes. Such a lock is of special advantage in instances where it is desired to leave a window open a short dis t-ance at the bottom or top, to prevent either sash from being moved fa r enough to permit the entrance of a person.
Figure 1 is a vertical section of a portion of the upper and lower sashes of a window having a lock embodying this invention. F 2 is a front view of the parts shown in Fig. 1. Fig. 3 is a view similar to Fig. 1, the lock being moved to permit unobstructed movement of both sashes. Fig. l is a longitudinal vertical section of the lock.
a represents the meeting-rail ofthe lower sash; Z) the meetingrail of the upper sash, and 0 one of the uprights of the upper sash.
The lock embodying this invention 0011- sists of a plate (Z, bent intermediate its length, or otherwise constructed, to form two parallel, transversely arranged shoulders (Z, cl, separated by a recess (Z and having at its extremities holes adapted to receive attaching-screws. A screwthreaded post 6 is secured to the plate (Z between the shoulders. An arm 7", having a hole through it at one end adapting it to be loosely arranged on the post, is made of a width approximately equal to the distance between the shoulders, so as to enter the recess and be held from turning therein by said shoulders when extended laterally from and arranged at right angles to the plate cl, yet it may be moved along on the post and swung into a position in parallel with the plate (Z when desired. A thumb-nut g is arranged on the post 6 which acts to hold the arm 7 securely in the recess (Z between the shoulders, yet it may be turned on the post to permit said arm to be moved along on the post, out of Specification of Letters Patent.

the recess, and swung into a position in parallel with the plate. The post, preferably, has a head 0, which prevents the removal of the thumb-nut. The lock, thus constructed, is attached to one of the uprights of the upper sash, as shown in Fig. l, and when in use its arm f is extended at right angles to the plate, being seated in the recess (Z and held securely therein by the thumb-nut g, and also by the shoulders (Z, cl. Said arm thus extends over the top of the lower sash and limits the upward movement of the lower sash and also the downward movement of the upper sash. Said lock will be attached to the upper sash at any suitable point according to the distance it is desired to lower and raise, respectively, the upper and lower sashes. hen it is desired to raise the lower sash or lower the upper sash a greater distance than is permitted by the lock, the arm 7 will be swung into a position in parallel with the plate (Z, as represented in Figs. 3 and 4t, and when in such out-of-use position unobstructed movement of both sashes is permitted.
The lock herein described may be cheaply manufactured and is very strong and when the arm is arranged between the shoulders cl, cl, will resist a very severe strain.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is The sash lock herein described consisting of a plate adapted to be attached to one of the uprights of the upper sash, having a pair of transversely arranged shoulders separated by a recess, a screw-threaded post secured to said plate and disposed in the recess thereof, between the shoulders, an arm loosely arranged on said post which is made of a width approximately equal to the distance between the shoulders, and a thumb-nut arranged on said post for holding the arm confined in the recess when extended at right angles to the plate yet permitting said arm to be moved into a position in parallel with the plate, substantially as described.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
GEORGE M. BLANDFORD.
