' NEW BRITAIN, CONNECTICUT,

l Letters-Patent No. 85,753, dated January 12, 1869.

The Schedule referred to in these Letters Patent and making of the same.

Be it known that I, W. T. MUNGER, of Branford, in the county of New Haven, and" State of Connecticut, have invented and made a certainnew and useful Improvement in Locks; and I do here by 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- Figurel is' an' elevatron of the lock,'wth"the cap# plate removed, and the parts in the usual position;

Figure 2 is a similar View, with the parts in lsuch a positionl that'the latch can be reversed; and

Figure 3 is a vertical section at the line :c x.

Similar marks of reference denote the same parts.

. Locks have heretofore been made with reversible latches operated by a handle acting through ahnb and horse-shoe slide. A

My inventionrelates to that class of looks that are provided with. a sliding latch, operated' upon directly.

by a knob that is drawn back.

My improvement in locks consists in a reversible latch, combined with a slide and a knob, that may be connected with that slide from either side of the lockcas'e. Thereby my lock is adaptedA to being placed on either right or left-hand doors.

In the drawinga is the box of the lock b, the cap-plate, removed in figs. l and 2; c is the front plate of the lock; all of any usual character,and either adapted to being let into a mortise in the edge of the door, or screwed upon its surface. I have represented the former style.

w d is the latch, formed with a shank, 2, passing at the rear end into the slide e, in which it may be turned when the .parts are inthe position shown in iig. 2, to bring they bevel of the latch either way that may be desired, the .round base 3 'of the latch dturning in the square mortise in the plate c.

The spring f, acting between the guide g and latch d, projects the same and in the slide e-is a hole into which is screwed the withdrawing-knob, shank, or loop, h.

The hole in the slide c goes rightthrough, so that the knob h may be screwed in from either side, and in the box cv of the lockemd the cap-plate 19, are mor-titres or slots, as at t', so that the knob or shank h may pass through the same into e, and the length ofthe mortise 'i is such as to prevent the latch d being proj ected, as in fig. 2, (so that it can be reversed,) except when the shank h is removed from the slide e.

The latch can be withdrawn by a key entered fromv either side into, the key-holes 7c, and acting upon the tumbling lever l on' the fulcrum m, and 'n is a dog, upon the fulcrum o, that can be moved when thelatch is drawn into the case, so as to hold the same by coming up against the forward end of the slide e.

When this lock is inserted in a mortise in the door,

an escutcheoniplate with a slot should be employed, as

seen Aat p, g. 3, for the shank of the knob to slide in.

What I claim, and desire to secure by Letters Patent, is

The reversible latch d, connected to the slide e, in combination with the lknob or shank h that screws into the slide e from either side, and passes through one of the slots in the cap-plate or lock-case, substantially as set forth.

In Witness whereof, I have hereunto set my signature, this day of July, A. D. 1868.

Witnesses: W. T. MUNGER.

CHARLES PECK, I EDWD. L. PRIOR.
