ANDREW M. RANTZ, OF OAMBRIDGEPORT,.AND CHARLES L. ENGELHARDT, OF BOSTON, MASSACHUSETTS.

FASTENER FOR THE MEETING-RAILS OF SASFHES.

SPECIFICATION forming part of Letters Patent No. 275,706, dated April 10, 1883.

Application filed October 13, 1882. (No model.)

To all whom it may concern.'

Be it known that we, ANDREW M. RANTZ, a citizen of Sweden, now residing at Oambridgeport, in the county of Middlesex and State of Massachusetts, and CHARLES L. EN- GELHARDT, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have jointly invented certain new and useful Improvements in Win- Io dow-Sash Fasteners; and we do hereby declare that the same are fully described in the following specification and illustrated in the accom panyiug drawings.

This invention relates to improvements in window-sash fasteners, and it is' carried ont as follows, reference being had to the accompanying drawings, in which- Figure 1 represents a plan view of the de vice shown in a locked position. Fig. 2 repzo resents a l'ront elevation of it shown as locked. Fig. 3 represents a vertical section on the line A B, shown in Figs. 1 and 2. Fig. 4 represents a side elevation of the device shown in the act of locking and securing the sashes together.

Similar letters refer to similar parts wherever they occur in the different parts of the drawings.

In the drawings, a. represents the lower por- 3o tion Aof the outer window-sash, and b represents the upper portion of the inner windowsash, as usual. To the sash a is secured the striker a', provided on its upright part with a slotted perforation, a, for the reception of the 3 5 latch-lever, hereinafter to be described. To

the sash b is secured the plate c," provided with vertical bearings c' c,through the upper ends of which passes the screw, pin, or rivet 0"', as shown.

d is the latch-lever, journaled on the pin 0 between the bearings c c. The outer end of the latch-lever d is provided with a hooked projection, d', adapted to be swung into the slotted perforation a on the striker a when the sashes a and b are brought in proximity to each other, and thus to effect a strong and secure lock between them by moving the latchlever d from the position shown in Fig. 4 to y the position shown in Fig. 3, which is done by depressing the `handle d, that forms a rear extension of the latch-lever d, as shown in said ii gures. For the purpose ot' automatically retaining the latch-lever l in its locked position, as shown in Figs. 1, 2, and 3, we employ the lock cam or lever h, hinged at h tothe plate c, and provided with a thumb-piece, 7L, by means of which it is operatedto be swung back against the rear portion ofthe latchlever d, as' shown in Figs. 1,2, and 3, and by means of which the latch-lever is prevented from being detached from the striker until the lock cam or lever h is swung to one side of the 1atchlever cl, which latter is then automatically caused to swing backward on its fulcruni-pin 0 by the influence of a suitable spring-wire, g, which is coiled around the pin 0r screw 0', with its free ends resting against the rear' of the vertical bearings c o and its looped end pressing on the under side of the handle or extension d, as shown in Figs. 3

and 4.
