Patented J Illy 16,1918.
Application filed April 19, 1917. -.Seria1 No. 168,235.
To allV whom t may' concern Be it known that I, HARRY BERMAN, a citizen of the llnited States. residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Automatic Sash- Locks. of which the following is a specification.
The primary aim of this invention is to provide a` simply and durably constructed sash lock which will become automatically operative on movement of the sash or sashes of a window, and it consists in a keeper mounted on one sash and a spring projected latch that is releasably supported in an inoperative position to be engaged. during movement of the sash by an obstruction or trip for releasing and allowing the latch to move to an operative position,
The invention further resides in au automatic sash lock which may be manually operated to lock the sashes in various partiallyopen positions for ventilation.
Tn the drawing Figure I is a fragmentary perspective view of a window embodying the present invention and depicting the latter in an iuoperative position about to be automatically tripped or released for movement to an operative position.
Fig. 2 is a vertical sectional view showing the sash lock inoperative in full lines and operative in dotted lines, and
Fig. 3 is a horizontal section of the sash lock 1n inoperative position.
Referring more in detail to the drawing and using similar numerals of reference for corresponding parts throughout the several views, 1 designates the window frame having the upper sash 2 and the lower sash I, arranged therein for vertical sliding.
ln the inner face of the upper sash and at one side thereof is secured a flat catch plate 4 having a vertical series of openings 5, the upper walls 6 of whicharc straight while the lower walls 7 are preferably curved downwardly.
On the top of the lower sash is secured a casing 8 having perforated base flanges 9 through which the securing screws 10 are passed. This casing is formed with a latch chamber ll which has its forward end open and its rear end closed by an end wall 12. A latch bolt 13 has its forward end beveled underneath, as at 14, and is slidabl; disposed in the casing chamber, a stem l5 eing cari wall .12.
rind bythe bolt.` and guided through the end A coiled spring 1G cncircles the stem 15 between said end wall and the shoulder 17, formed by said latch bolt, for urging the latter to a projected position.
Rotatably mounted on the free outer end of the stem is a winged head 18 and extending from the opposite sides of the wall 12 in parallel relation is a pair of arms or supports 19 on the outer ends of which the head 18 is adapted to rest, when the latch is retracted, for retaining the latter inoperative. Should the head be rotated to disengage its wings from the arms 19 the coiled spring will project the latch and move the head between said arms as illustrated b v dotted lines in Fig.
ObviouslyT this rotation of the head may be manually accomplished. and such is thc preferred operation for locking the sashes partially opened. but to positively insure '.1 locking of the sashes when they are closed, the turning of the head is effected automatically by a trip pin or screw Q0 that is arranged on the frame in the path of the head 18 when the latter is engaged with the arms. This pin is disposed on the frame slightly above the normal position of the head so as to engage and release the latter immediately before the window is closed. Consequently while the head is supported by said arms 19. the sashes may be raised and lowered without springing the lock. However. as the lower sash approaches its limit of closing movement the trip pin rotates the head from off the arms to permit the coiled spring 1G projecting the lock into engagement with the catch plate. Thus, when the window is closed the sashes are automaticallyY locked by a device so arranged as to be inaccessible from outside the window. It is apparent that the element 20 may be arranged in different relative positions so as to cause the release of the latch at the desired time and either in the opening or closing movement of the sash.
lVhile the foregoing description has been very minute, it is understood that in the manufacture of the device such practical changes may be resorted to as fall within the scope of the appended claims.
Having thus described my invention, what` I claim as new is A window sash lock, comprising a casing closed at its rear end, a spring actuated bolt mounted therein and having a portion proj eeting through the rear end of the casing, a adapted to be ilnpinged upon movement of head loosely mounted on the rear extremity the sash to turn the head relatively to the 10 of the projecting portion of the bolt for robolt to disengage the head from the arms tation, the sides of the Casing having intewhereby the bolt may move into locking pogral extensions forming spaced arms With sition.
the ends of which the rotatable head is en- In testimony whereof I atlix my signature. gageablo to hold the bolt retracted in the easing, and relatively stationary means HARRY BERMAN. [11. s]
