Leners Patent No.'11o,o71, dated December 13, 187e IMPROVEMENT IN COMBINED LOCKS AND LATCHES.

The Schedule referred to in these Letters Patent and making parl: of thesame.

To all whom it may concern.-

Be it known that AI, FRANCIS' M. RANoUs, `of Yreka City, in the county of 'Siskiyou and State of California, have invented a new and useful Improvement -in Combined Lock and Latch; and I do hereby declare that the following is 'a full, clear, and exact description thereof, which will enable othrsskilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this specification.

Figure 1 isa side view of my improved lock and latch, the inner plate of the lock-case being removed.

Figure '2 is a detail sectional view of the same, taken through the line a: x, fig. 1.

Figine 3 is a detail view of the catch.

Similar letters of refcrenceindicate corresponding parts. y My invention has for its object toimprove the construction of my improved gate-latch patented October 26, 1869, aud numbered 96,147, so as to makeit more convenient .in use and more effective in operation, enabling it to be used in eithera lock or latch and It consists in the construction and combination of various parts, as hereiuaftermore fully described.

A is the case of the lock, which is secured to the door by screws in the ordinary J4ina-nner.

' iBv is the inner plate of the case A, which is secured in .place by a screw passing through it -and screwing into the stud al formed upon the,l case A.

g ,C is the sliding latch, the forward part of' which passes out through a slot in the forward end ange of the case Af.I

'.lhe forward 'end of the latch C has a downwardlyprojecting shoulder or hook formed upon it, which is notched upon its inner edge close to the body. of the latch, as shown in fig. 1, forming a projection, c', which enters -a hole, d', in the neck of the double-inclined catch D. 1 l The catch D is beveled or inclined upon its upper and inner sides, so that when the door or gate is swung shut the said catch may raise the forward end of the latch'C, and at-thc same time draw it outward, bringing it into proper position for the projection c' of the said hook-latch C to be drawn into the hole df of the catch'D'.l l l E is the spindle, to the ends of whichthe knobs F are attached in the ordinary manner.

G is the hub', through which the spindle E passes, and by means of which the knob-spindle is enabled to operate the latch C.

In the rear vpart of the latch C is formed an oblong hole, C, to receive the hub G.

'.lh'einner side of the-latchlC, at the sides of the hole c, is notched Vor recessed, to form shoulders for the cams or arms g of the hub G to press againstin operating the latch, said notch or recess being made of such a length that, when the lower cam or arm gf has pushed the latch C forward sufficiently .`ar, the

upper cam or arr-'n g' may strike against lthe shoulder is connected with the case A, as shown in figs. 1 and 2.

By this arrangement the same spring I will draw the latch back, and at the same time draw and hold the forwardend of said latch down.

Upon the forward edge ofthe lower or outer end of the arm H is formed a hook or shoulder, h', to receive the stop J which locks the latch, by preventing, when -in the positions shown in the drawing, the latch-j() vfrom being drawn back to unlatch the door or gate;

The stop J is pivoted to a pin, K, attached to the plate of the case A. A

To the outer end of pin K, upon the outer sidev of the plate of the case A, is pivoted a disk, L, provided with .a thumb-piece, knob, or other handle, M, to enable it to be conveniently operated.

Io the disk L is attached a pinN, which passes in through a curved slot, c2, in the plate of' the c ase A, the said curved slot u being madeof such alength as to limit the movementof the stop J.

In the inner plate B ofthe case A, -directly opposite the inwardly-projecting end of' the pin K, is formed a .key-hole, b', to allow a key to be inserted from the outside of the door, to unlock the latch when required..

The outer edge of the stop J is notched around the pivoting-pin K, to adapt it to receive a key, and t0 allow theguard of the said keyto strike against the body of the said stop, and thus operate-it." Having thus described my invention,

lI claim as new and desire to secure by Letters .Patent g The pivoted stop J, pivoting-pin K, pivoted disk L, provided witha thumb-piece, knob, or handle M,piu N, and curved slot az in the plate `B of the case A, in' combination with thearm H h of the sliding hooklatch C c', substantially as herein shown and described,- and for the purpose set forth.
