JAMES A. GIESE AND BERNARD S. FIELD, OF CHICAGO, ILLINOIS, ASSIGNORS TO THE ADAMS & WES'ILAKE COMPANY, OF CHICAGO,

ILLINOIS.

ILLINOIS, A CORPORATION OF SASH-LOCK.

To all whom it may concern:

Be it known that we, JAMES A. Gmsn and BERNARD S. FIELD, citizens of the United States, and residents of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The object of the invention is to provide a lock especially adapted for use on the windows of railway cars which is simple of construction and easy of operation.

The lock will ordinarily, although not necessarily, be fitted into the lower rail of the sash midway of its ends, its bolt extending through a suitable aperture in the sash rail to engage with the stile of the casing. The lock is rovided with a controlling finger-piece o considerable length, thereby providing for a firm grip, this finger-piece, however, controlling the lock whether moved in a right line or tilted by pressure upon one of its ends. The lock may also be released by movement of the finger-piece either upwardly or downwardly, and the finger-piece provides the necessary grip for applying lifting or depressing pressure for raising or lowering the sash.

The mechanism by which the invention is carried into practice is hereinafter described, and is illustrated in the accompanying drawings, in which- Figure 1 is a detail elevation of a window with the lock applied thereto; Fig. 2 is a rear view of the lock mechanism, some parts being broken away, the mechanism being shown in its normal position; Fig. 3 is a section on the line 33 of Fig. 2; and Figs. 4, 5 and 6 are views similar to Fig. 2, representing different movements of the fingerpiece and bolt-actuating levers.

The lock comprises a suitable casing, such as the face plate 10, having a depressed central portion 11 which is adapted to enter a suitable aperture in a sash rail 12. A fingerpiece or bar 13 is located within the central depression of the face plate, and is provided at its ends with extensions 14, 14, which project through and slide in slots, as 15, in the end walls, as 16, of the depressed portion of the plate.

A slide plate 17 is applied to the inner face of the depressed portion of the face Specification of Letters Patent.

plate 10, and reciprocates thereupon in suitable ways. As shown, such Ways are provided by means of gibs 18, 19, 20 and 21, secured to the face plate and lipping over the side edges of the plate 17. The bolt 22 is attached to the plate 17, and is normally advanced by means of a spring 23 of any suitable form, here shown as bearin against the rearward end of the last-name plate. The plate 17 is apertured, as shown at 24, 25, to accommodate a pair of T-shaped levers, designated generally by the numerals 26, 27, and also to provide shoulders against which two of the arms 28, 29, and 30, 31, bear, these shoulders facing toward the bolt 22. The levers 26, 27 are pivoted, as shown at 32, 33, to the depressed portion of the face plate 10, and on the longitudinal median line thereof. The arms 34, 35, of the levers 26, 27, to which power is applied, extend toward the ends of the face plate, and each is longitudinally slotted, as shown at 36, 37, to accommodate studs 38, 39, projecting from the finger-bar 13 through transverse slots 40, 41, in the face plate. Lateral movement of the finger-bar either upwardly or downwardly will, therefore, rock the levers on their pivots and move the plate 17 in opposition to the spring 23 for withdrawing the bolt. The bodily movement of the finger-bar in a right line, as to the position represented in Fig. 6, will actuate both of the controlling levers 26, 27, while a tilting movement of the finger-bar by pressure at either of its ends, as indicated in Figs. 4 and 5 will actuate a single one of the levers. In either case the effect upon the plate 17 is the same. The slots 40, 41, are, of course, of sufficient width to permit the pins 38, 39, to move in curved paths.

We do not desire to be limited to the de tails of construction as shown and described, as they may be variously worked out within the scope of the invention.

WVe claim as our invention- 1. In a sash lock, in combination, a suitable casing, a spring-advanced bolt, a laterally movable tiltable finger bar, and independent means actuated by each end of the finger bar for retracting the-bolt.

2. In a sash lock, in combination, a suitable casing, a spring-advanced bolt, a laterally movable tiltable finger bar, and independent means actuated by each end of the finger bar for retracting the bolt upon the movement of the bar in either direction from its normal position.

3. In a sash lock, in combination, a suitable casing, a spring-advanced bolt, a laterally movable tiltable finger bar, and inde- I pendent means actuated by each end of the finger bar for retracting the bolt upon the movement of either end of the bar from its normal position.

4. In a sash lock, in combination, a suitable casing, a spring-advanced bolt, a reciprocable plate to which the bolt is attached, such bolt having forwardly projecting shoulders, a pair of three-arm levers, two arms of each lever engaging shoulders of the plate, a laterally movable finger bar mounted upon the casing, and studs carried by the finger bar and being in engagement one with the third arm of each of the levers.

5. In a sash lock, in combination, a suitable casing, a spring-retracted bolt, a reciprocable plate attached to the bolt and having two pairs of forwardly directed shoulders, two levers fulcrumed upon the casing and each having two arms cooperating with one pair of shoulders, a laterally movable finger bar, and actuating connection between each end of the finger bar and one of the levers.

6. In combination, a reciprocable springa-dvanced bolt, a laterally movable finger bar, forwardly directed shoulders associated with the bolt and projecting laterally in opposite directions, a lever engageable with each shoulder, and actuating connection between opposite ends of the finger bar and each of the levers.
