Description

UNITED STATES PATENT OEEICE BENJAMIN BRAY, OF METHUEN, MASSACHUSETTS.
IMPROVEMENT IN SASH-FASTENERS.
Specication forming part of Letters Patent No. 54,286, dated May 1, 1866.
To all 'whom it may concern:
Be it known that I, BENJAMIN BRAY, of Methuen, of the county ot' Essex and State ot Massachusetts, have invented a new and useful lmprovennentin Windows 5 and I do hereby declare the saine to be fully described in the following specification and represented in the accompanying drawings, of which-.
Figure l'is a vertical section, and Fig. 2 a transverse and horizontal section, ot' a window frame and sash as provided with my invention.
The purpose ot' the said invention is not only to dispense with the usual cords and balancing-weights and pulleys of a sash, but to enable such sash to be raised and maintained at any desirable altitude within the window-traine, as well' as to be fastened either when closed or when raised or lowered to any position within the frame. My invention is applicable to either sash ot' the two contained in the frame.
In carrying out the said invention I tix to or into the vertical edge of the sash A or B a toothed rack, a, each tooth ot' which is made triangular' in transverse section. I also affix to the contiguous side of the window-frame and in a recess, l, formed therein a spring, c, provided at its free eXtrexnitywith a triangular tooth, d, to enter the space between any two next adjacent teeth of the rack, the spring' at or near its other end being fastened to the window-frame. In rear of the spring there is a projection, e, from a short shaft, f, which is arranged in the Window-frame and provided `being forced back so as to liberate its tooth d from the rack, but so that when the shaft is revolved so as to carry the projection sufficiently away from the spring the latter may be free to be forced back so as to liberate the vtooth d from the rack. The spring should be stiftl enough to prevent the weightof the sash from throwing the tooth out of the rack. Thus it will be seen that by the action ot" the spring and its tooth with the rack the sash will be retained at any altitude within the windowframe in which it may be; also, that in the application of force to the sash for the purpose ot' either raising or depressing it .the triangular tooth of the rack and spring will cause the tooth of the spring to be thrown out of the rack, so as to liberate the sash and allow it to move in the frame. f
I claim- The combination of the Vtriangular-toothed rack, the triangular-toothed spring-catch, and the locking device ot' the said catch, constructed, arranged, and applied to a window sash and frame substantially in the manner and forthe purpose as hereinbetore specified.
