FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 297,500, dated April 22, 188%.

Application filed November 19, 1883. (No model.) I

To all whom it may concern.-

Be it known that I, LoUIs J. CHURCH, of Washington, in the District of Columbia, have invented a new and useful Improvement in Sash-Locks; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to sash-locks of that class in which a lever turning upon a pivot in the inner sash hooks under an arm on the outer sash, and is locked by a gravity-latch.

My object is to provide a construction which can be easily made and is of ornamental appearance.

In the accompanying drawings, Figure 1 represents the lock in position upon a sash, with the shell or case partly broken away. Fig. 2 is a side elevation, and Fig. 3 is a plan view of the bottom of the look.

In these figures, A represents the shell or case, which covers the operating parts of the look. This may be made of any suitable material, preferably of the shape shown, and any desired amount of ornamentation may be put upon it. This case is attached to the inner sash by means of screws passing through projections formed with the case, or it may be secured in any other suitable manner. Within the case A is the catch B, turning upon a pin or screw, 1), passing through the case A. If desired, the pin or screw may pass into the sash entirely through the case, and thus afford means of attachment without the use of the projections described above. The catch B is somewhat longer than the width of the case, which is consequently slotted upon one side, as at c, to receive the catch when in an open positionthat is, when the window-sashes are unlocked. The catch is adapted to be turned upon the pin 1) to throw its hooked end 1 across the division between the inner and outer sash, and in order to secure this end to the other sash, and thus lock both the inner and outer in a closed position, I provide a continuation, C, of the shell or case A. This I secure to the outer sash in any convenient manner, and in such a position that it forms approximately with the shell A a divided circular case. It is provided with a top plate,

2, and back wall, 3, which is slotted for about half its length, as shown at 4. This part 0 is secured to the outer sash in such relation to the part A upon the inner sash that, when the catch B is turned to lock the sash, the reduced portion 6 of said catch will pass into the slot 4, with the hooked end 1 upon the outside, thus preventing movement of either the inner or outer sash, and locking them securely in a closed position.

In order to operate the catch B conveniently, so as to lock or unlock the sash, I provide the following: I bifurcate the inner end of the catch, (marked 7,) or cut it out, as shown in the bottom plan View at 8. and in this space pivot a supplemental latch, E. The inner end of the latch, working in the space 8, is weighted or made heavier than the outer end, which extends through a slot in the wall of the case and terminates in a suitable thumb-piece, 9. The slot in the case extends along the bottom thereof from the front to near the outer edge of said case for about a quarter of its circumference, which is sufficient to impart the necessary movement to the catch to lock and unlock the sash. At the extreme front and rear portions of the slot are deeper slots 10, into which the latch is forced by the gravitation of the inner and heavier part, when the latch is opposite such slots; and it is thus evidentthat in the positions in which these slots occur the latch will be held and prevented from further movement until the thumb-piece has been depressed and the latch moved to the right or left out of saidslots. As these slots occur at each end of the long slot, the latch will consequently be held from turning in the locked and unlocked positions of the catch, respectively. This construction is simple and effective, and enables the latch to be held securely without the liability of becoming unlocked when locked, or vice versa, from jarring or other causes. The latch operates by gravity, and is consequently positive in its action.

I am aware that the general form of the locking-catch and latch acting by gravity is not new.

What I claim is- In a sash-lock, the case A in the arc of a In testiinonywhereof I have signed my name circle, connected to the inner sash, and proto this specification in the presence of two Vided with the slot and locking-notches 10, subscribing Witnesses. the locking-catch B, the 1atch E, Weighted at 5 its inner end and incloscd Within said case, LOUIS J. CHURCH.

and adapted thereto, combined with the part 0, connected to the outer sash and forming with the part A2 complete circle, and adapted to receive the end of the catch B, substantially IO as described.

Vi tnesses:

JOHN B. THOMPSON, EDWD. H. WVILSON.
