TO ALL WHONI I'I MAY CONCERN:

Be it known that I, BALTBASAR SEEGMLLER, of the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Locks; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is an elevation of my said lock with the cap-plate removed and in the position adapted to use as a latch. i i

Figure 2 is a similar view with the parts in position vfor use with a key; and

Figure 3 is an elevation of the exterior of the lock-case. I

Similar marks of reference denote the same parts.

My improved lock is adapted to use as a lock operated by a key, or a latch operated by a handle, a hooked tumbler being provided between the bolt and the saddle of the handle, so that when said hooked tumbler is disconnected from the latch-bolt it can lbe projected further, and operated only by the key or by a stud inside the door; or when said hook is connected to the saddle of the handle the bolt becomes only a spring-latch `operated by the handle, the end of the latch being inclined so as to be pressed back in Closing the door.

In the drawing, a represents the lock-case, of any usual size or character. b is the square for the spindle of the handle, with the cams c c, taking the saddle-piece d of the latch that slides in ways onthe inside of the lock-case. c is a sprinzgr to the said saddle, to project it forwards, and, by the connecting hooked tumbler f, throw out the bolts. g is the latch-bolt, that is bevelled at its end, and guided between studs or slides within the lock-case, so that it will slide endwise; and h is the key-stud for a key that acts upon the talon z' of the bolt, to project or retract the same. The tumblerf is set on a stud, o, upon the bolt, and kept down by the spring k. lis the hooked end of this tumblerf, taking a stud, n,on the saddle. m is a knob on the tumbler f, passing through a slot, s, in the lock-case, which slot is formed with an offset that forms the tumbler-stud.

When the hook Zis over the stud n the lock works as'a latch, beingacted upon by the handle and thrown forward by the spring c, the shank of the knob m sliding freely in the slot s; but when the key is used the tumblerf is lifted and unhooked from the studn, and the bolt thrown forward into the position in iig. 2. The shank of the knob m falling behind the offset in the slot 8 prevents the lock being opened until the tumbler is raised by the key from the outside, or by the knob m from the inside, and the act of withdrawing the bolt connects the tumbler and bolt with the handle-saddle, so that it can act as a latch until the bolt is again projected by the key from the outside or the knob m from the inside. The latch' and look may be placed so that the bolt works either horizontally or vertically.

What I claim, and desire to secure by vLetters Patent, is-

The hooked tumblerf pivoted on the bolt, and provided with a knob passing through a slot in the lockcase, in combination with the saddle operated by the handle, substantially as and for the purposes set forth.

In witness whereof` I have hereunto set my signature this sixteenth day ot' March, A. D.. 1867.
