Application filed March 18,1886. Serial No. 195,769. (No model.)

To all whom it may concern:

Beit known that I, EdwinR. Ferry, of the city of New Haven, county of New Haven, State of Connecticut, have invented new and 5 Improved Sash-Locks, of which the following is a full, clear, and exact description.

This invention consists in a novel device for drawing the rails of the upper and lower sash of a window together to exclude the cold and io dust, and to lock them together so that neither sash can be moved until released by the lock from the interior, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying 15 drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a view in perspective of my improved sash-lock secured to the upper 20 and lower rails of window-sash, and in position to permit either sash to be raised or lowered or to be locked together, as required. Fig. 2 represents a plan top view of my sashlock, also secured to the dividing-rails of the ²5 upper and lower sash of a window, showing the two rails drawn snugly together and locked, so that neither sash can be moved until unlocked from the interior. Fig. 3 represents a longitudinal sectional elevation of this jo lock secured to the upper and lower rails of window-sash, the sash being also shown insection, and the dotted lines represent the fastener unlocked, the same as in Fig. 1, to permit the sash to be raised or lowered without inter35 feringwith the lock; and Fig. 4 shows a modification of the locking-stud.

A A' in the accompanying drawings represent the dividing-rails in the upper and lower sash of a window. This lock is secured to the 40 upper sides of these two dividing-rails A A' by screws, in the usual manner.

On the dividing-rail A' of the upper sash is secured a plate, B, having a notched stud, J, projecting therefrom, as represented in the sev45 eral figures.

On the upper dividing-rail, A, of the inner and lower sash is secured a plate, E, upon which is mounted a locking-lever, D, carrying a latchbar, C, by which the rails of the two sashes 50 are drawn snugly together and locked. This latching and locking part consists of a plate, E, secured to the upper side of the dividingrail A of the lower sash, from which extend two ears or sides, .F F. To these sides F is pivoted a locking-lever, D, which is provided 55 on its two sides with eccentrics G G, as shown in Fig. 3. To these eccentrics G G is fitted the latch-bar 0, having a cross-bar, I, which passes over and is drawn beneath the notched end J of the stud on the plate B by the eccen- 6o tries G G on the locking-lever D when the lever is turned inward so as to rest upon the inner edge of the plate F, as represented in Figs. 2 and 3.

Theoperationofthissash-lockmaybebriefly 65 described as follows: To draw together the dividing-rails of the two sashes, the latch-bar 0 and locking-lever D are placed in position, as represented in Fig. 1. The locking-bar D is then turned inward, by, which operation the 70 cross-bar I of the latch is drawn beneath the hooked end J of the stud on the plate B, drawing the two rails together, closing the space between them, and locking them firmly together, as shown in Figs. 2 and 3. _ 75

To unlock the rails of the two sashes, the locking-lever Dis turned to the position shown in Fig. 1 and in dotted lines, Fig. 3, when either or both sashes may be raised and lowered at pleasure without interfering with the 80 lock.

It is quite evident that instead of the eccentrics G G, to move the latch-bar back and forth to engage and d isengage with the hook J, crankpins may be substituted therefor which would 85 accomplish the same movements as the eccentrics.

In Fig. 4 is shown a modification wherein the notched end J of the stud on plate B is provided with two notches, so that in case the 90 meeting-rails do not align the latch-bolt G will be sure to engage the stud.
