SPECIFICATION forming part of Letters Patent No. 524,631, dated August 14, 1894.

Application filed July 22,1893. Serial No. 481,220. (No model.)

To all whom it may concern:

Be it known that I, THOMAS CHOPE, a citizen 0f the United States, residing at San Franclsco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the iifvention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved sash fastener which is adapted to be secured to the top rail of the lower sash, and lock both the sashes.

The object of my invention is to provide a device of this class that can be operated to lock either or both the sashes at any desired po1nt, and a further object is to provide a lock of this class that can be applied to either the right or left hand side of the rail.

With a view to simplicity and cheapness, my invention consists of but two parts, namely, a sliding locking bolt and a lever for actuating the same, these parts, however, are of peculiar and novel construction, as will be fully set forth in the specification, and pointed out in the claims.

In the drawings forming a part of this specification, Figure 1, is a plan view of my improved device as applied and used. Fig. 2, is a section on the line 22 of Fig. 1. Fig. 3, is a detail view of the bolt, and Fig. 4, a View of the lever.

Referring to the drawings, A, indicates the upper sash, a, the lowerrail of the same, and a the left stile. B, indicates the lower sash, and b, the top rail, all of the above named parts being of the usual construction.

0, indicates my improved sash lock secured upon the top rail 1), near the left hand end of the same. In practice, this look must be placed near either end, ther on.

The lock 0, is made of metal, and consists of a locking, sliding bolt, 0 and a lever O for operating the bolt. One end 0, of the bolt 0' is shaped to bear upon the stile a. of the as will appear farupper sash, while the opposite end is con- 5c structed with the inwardly curved arms, a c, which form an essentially circular socket to receive the circular head 0 of the lever C The bolt is also formed with a longitudinal slot 0 through which is passed a screw 0 for securing the bolt to the top rail, and by means of the slot 0 the bolt is permitted a longitudinal movement so that the face 0 may bind against the stile.

The head 0 of the lever C is formed with two eccentric apertures through which is passed a screw 0, for securing the lever to the rail, said screw being passed through one particular hole according to the end of the rail. Pivoting the lever in this manner makes the head 6 an eccentric and as the free end of lever is moved from side to side, the bolt 0 is moved back and forth.

The arms 0 e, do not meet, but leave sufficient space for the insertion of the lever, and the under face of the lever is recessed at 0 to permit said lever to move freely over the said arms.

The sliding bolt is provided with a flange or lip c which projects centrally between the arms 0' c, and is adapted to rest above the head 0 of the lever, and hold the parts together when great pressure is applied.

The inner wall of the socket is recessed at 0 so that the pressure in looking is thrown to the sides of the pivot pin, and not in line with the point of contact.

To apply my improved lock, the lever is first secured to the top rail near one end, and the screw will be passed through the right or left aperture according to whether the lock is to be placed at the right or left hand end of the rail. The sliding bolt is then arranged so that its arms embrace the head of the lever, and after being properly adjusted, is secured to the rail by means of the screw passed through the slot.

The parts being arranged as described, when it is desired to lock the sashes, the lever is thrown around as shown, in full lines, forcing the end of the bolt against the stile of the upper sash, and locking the sashes by frictional contact, and it will be readily seen that the sashes lea-n be locked-in an desired position, in'as'inueh as the sliding bolt binds upon the stile and not upon the bottom rail.

Having thus described my invention, what I claim is- 1. In a sash look a sl'i'dingbolthaving a longitudinal slot to receive a screw for securing the bolt to the sash and having curved arms forming a circular opening in rear of 1a said slot, in combination with a lever having a circular head fitting said opening andhaving two holes in its head upon opposite sides of the center thereof to receive apivot screw, 2 substantially as described.

2. In a sash lock, asliding bolt having j magi-mama slot and circular arms in rear thereof forming a circular opening, a lever having a' circular head fitting said opening and having two pivot openings located upon opposite sides of the center thereof, and a "cap piece o iproj'ecti'ng from the sliding bolt
