PATENT OEEICE.
STEPHEN D. ARNOLD, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO P. & F. CORBIN, OF SAME PLACE.
IMPROVEMENT IN FLUSH-BOLTS FOR DOORS.
Specification forming part of Letters Patent No. 139,647, dated June 10, 1873i; application led May 2, 1873.
Awith a hook at the end of the thumb-piece that catches at either one side or the other of a block that is provided at the back ofthe bolt-plate; thereby the bolt is retained in either a projected or a retracted position.
In the drawing, Figure lis a vertical section of said bolt, and Fig. 2 is an elevation at the back or inner side of said bolt.
The plate a is made of any desired size or `shape, with the usual flange b, through which the bolt c passes. This bolt is guided in the eye dand provided with a shank, c, to which the thumb piece or pla-te f is connected by a joint, c'; and this plate closes the rear of the opening l through the plate a, and in that opening l is the cross-rib o upon the plate f for the thumb to act against in moving the bolt up or down. This plate f has to be pressed back before it can be moved endwise, because thehook s at its end comes either one side or the other of the block 'r at the back of the plate a, which hook and block hold the bolt in Whatever position it may be moved to,`
because the spring u, applied near the joint t' within the shank e, presses the hook s toward the plate a, to causethe same to catch against the edges of the block r when the bolt reaches j its extreme movementin either direction.
I claim as my inventon- The thumb-piece f, with the hook s at the end thereof, in combination with the spring u` Within the bolt-shank e, and the block r at" the back of the plate a, in which plate a is an opening for the rib o of the thuln b-piece f, as setforth.
Signed by me this 21st day of April, A. D.
