FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 443,356, dated December 23, 1890.

Application filed OctoberZS, 1890- Serial No. 369,056. (No model.)

To aZZ whom it may concern: Figs. 1 and 2 show the position of the parts Be it known that I, ERNEST M. CATTLEY, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a certain new and Improved Windowforming the fastening as they will appear when the sash is locked. In order to unlock the sash, the catch D is pushed into the casing 0, which action forces the pawl F out Fastener, of which the following is a specithrough the opening I), causing it to engage fication. with the wall of the casing O, as indicated in The object of the invention is to design a Fig. 3. The sash B may then be raised, and simple device for securely fastening or lockwhen the plate G, fixed to it, reaches the head [0 ing the sashes of a window in such a manner of the pawl F, as indicated in Fig. 3, it raises that the said fastening cannot be unlocked the said head clear of the wall of the casing,

25 2 is a sectional view through as y of Fig. 1. be readily opened by inserting a thin blade Fig. 3 is a sectional view showing the posibetween the joint of the sashes. Owing to tion of the fastener when. the window-sash is the position of the plate G, it is not possible being raised. to reach the catch by such means. Therefore In the drawings, A represents the upper it is impossible to open the sash from outside 30 sash, and B the lower sash. without breaking the glass.

0 is a metal case secured to the sashA and Vhat I claim as my invention is containing a catch D, pivoted at a. 1. A catch D, pivoted in the casing C and E is a spring arranged inside of the casing actuated bythe springE,in combination with 3, as indicated in Figs. 2 and 3, so as to hold the pawl F, pivoted to the catch D, substan- 35 the catch D in the position indicated in Figs. tially as and for the purpose specified.

l and 2. 2. The catch D, pivoted in the casing Cand F is a pawl pivoted on the upper end of the actuated by the spring E, and the pawl F, pivcatch D. When this catch D is pushed into oted directly to the top of the catch D and the casing, as indicated in Fig. 3, the pawl F engaging with the. casing O, in combination 40 is forced out of the casing Othrough the openwith the plate G, fixed to the sash B and ing 1), and as it passes the wallet the said shaped to fit over the lugs II, substantially as casing it falls byits own gravity and engages and for the purpose specified. with the said wall, as indicated in Fig. 3, so Toronto, October 9, 1890. as to hold the catch D inside of the casin g C 45 clear of the lower sash B, (See Fig. 3.) ERNEST M. GA'FLEY.

from outside, the same being arranged to lock itself when the sashes are closed; and it consists, essentially, of a spring-catch connected to the upper sash and so constructed that it may be readily pushed and held clear of the lower sash when it is desired to open the window, the raising of the lower sash resetting the catch, so that it will reset itself to lock the sash when closed, substantially as here inafter more particularly explained. and then definitel y claimed.

Figure 1 is a perspective view showing my improved window-fastener in position. Fig.

G is a plate fixed to the sash B. This plate G extends over the sash A, and is shaped so as to fit on each side of the casingO and over lugs H, formed on the said casing.

thus releasing the catch and permitting it to be pushed out of the casing by the action of the spring E. hen the sash is lowered, it pushes the catch D far enough in to allow it to pass, but notsufficiently far to push out the pawl F. In lowering the sash the plate G passes over the lugs H and draws the two sashes together, thus holding them steady and preventing any disagreeable rattling. It will be observed that a curved projection I is formed on the plate G, so as to fit below and form a close connection with the catch D.
