SPECIFICATION forming part of Letters Patent No. 399,141, dated March 5, 1889. Application filed Sept-ember l, 1887- $erial No. 248,520 (No model.)

T Mi whom it may concern.-

Be it known that I, WILLIAM Snnnwoon i ing had to the accompanying drawings, and g to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a view of lockcase with works removed. Fig. 2 is a plan view of lock. Fig. 3 is a front view of baseplate D. Fig. 4 is a detail view of parts of lock.

The invention relates to that class of locks known as mortise-locks, wherein the mechanism within the casing can be operated upon by mechanism contained in a separate shell or cylinder lock, (for which a separate application for Letters Patent has been made under even date, Serial No. 248,519,) that maybe attached to the mortise-lock after said mortise-lock has been placed in its seat, or the mortise-lock can be operated without the cylinder-lock mechanism.

Referring by letter to the accompanying drawings, A designates the main portion of the lock-ease having a removable wall, said wall being secured in place by screws passed through screw-holes near the ends of said removable wall into internally-threaded lugs 0, cast on the inner faces of the end walls of the main portion A, near the transverse middle lines of said end walls.

D designates the face-plate of the lock, said face-plate being recessed on its inner face to receive the edges of the side plates and end plates of the lock-case. On its inner face, near each end, the face-plate D is provided with inwardly-projeciing lugs E E, through which screws F are passed into internallythreadcd lugs G, cast on the main portion of the lock'case and projecting inwardly from the end walls of said main portion.

The faceplate D is provided with openings H and I, through which the latch-bolt and lock-bolt, respectively hereinafter described, work when operated.

The latch-bolt comprises the head .I and the flat stem K, the latter being contained within the case and branched atits inner end to form the arms L and M. Said arms are provided with an gu lari y-bent en ds that project toward the removable wall of the lock-case and form the tumblers N P. Tlhebroader arm or branch, M, of the latch-bolt is slotted longitudinally at Q to receive a stud, R, projecting inwardly from the enlarged portion S of a short rib, T, cast on the inner face of the fixed wall of the lock-case at the lower side of the opening d. In this opening XV one end of the hub U for the lttClbbOltSPillCllG works. The latch-bolt stem K is provided with a pin or stud, 7", which projects toward the fixed wall of the lockcase.

j is a spring seated in a. cleft-stud, 12, said stud being cast integral with the fixed wall of the lock-case. The outer or free end of said springj presses against the pin or stud j and tends normally to press the latch-bolt outward. The latcl1bolt J is also provided on its lower edge with a transverse groove, 5.

is a sector-shaped buffer hinged to the inner face of the faceplate D, and has the stud s, which travels in the transverse groove 5' of the latch-bolt. This buffer tstrikes the keeper before the latch-bolt comes in contact therewith, and, having a rotary motion, moves the latch-bolt back or inward and relieves the look from any shock or jar when closing the door.

A plain rib, Y, is cast on ihc inner face of the fixed wall of the locleeasc opposite to and parallel with the rib T, and upon these two parallel ribs T and Y the arms L and M of the latch-boltslide when the latch-bolt is operated.

Resting upon or against the inner faceol" 7 the latch-bolt is abranclnnl slide, W, said slide being provided with a longitudinallydisposed slot, X, in its stem, said slot receiving the reduced portion of a shouldered stud, Y, said stud Y being cast integral with the fixed wall of the lock-ease, projecting inwardly and at right angles thereto. The arms Y Z of the slotted branched slide VJ are provided with angularly-bent ends 1 2. Said ends project inwardly or toward the removable wall. The hub U for the knob-spindle is provided with arms 3 and i, the inner edges or faces of said arms being plane and engaging the angularly-bent ends 1 2 of the slotted branched slide V.

On its lower edge the stem K of the latchbolt is cut away or recessed, as at 5, to receive the bentend 6 of the slotted shouldered sliding fence 7. This fence 7 is provided with two slots, 7 7', and an arm, 7 f, extending laterally and at right angles to its end, said arm engaging a stud or projection, 49 of a revolving-cylinder lock. Near the latch-bolt stem and opposite the recess 5 a stud, 8','is cast 011 the fixed wall of the lock case. Looselypivoted on this stud is a slotted nsdarmn lever, 8, h ving v flange, 91

.it s innernpper edge,saidfiange serving as 'a lock or stopfor the latch-boltstem when the latter is projected. The slotted flanged lever is also provided with a slot, 10, near its free end, said slot being inclined at an angle to the parallel edges of said lever. The lever 8 rests upon the inner face of the fixed wall of the lock-case.

A double-armed lever, 11, is secured upon the cleft-stud 12. The head of said stud forms the seat or fastening-point for one end of a spring, 14, which forces the branched slide XV outward by pressing against a pin or stud, 15, near the slot X. The inner or longer arm of the lever 11 is provided with a pin, 16, which projects into the inclined slot 10 of the lever 8. The short arm of the lever 11 is provided with an elliptical pin, 19, on its outer end. P is the lock-bolt, having the stem 18, provided with the longitudinal slot 33 to receive a stud 30 on the boss 31, cast integral with the fixed wall of the lock-case. This stud 30 engages either one of the rectangular notches 28 29 on the lower edge of the arm 21 of the angle-lever 25, asthe case may requirethat is, it engages the notch 28 when the lock-boltis projected and the notch 29 when the lock-bolt is retracted.

23 is a curved recess on the upper edge of the lock-bolt stem, in which the elliptical pin 19 on the lever 11 seats itself when the lockbolt is projected.

on is a rectangular notch on the upper edge of the lock-bolt stem. The lock-bolt stem is also provided with the lugs m placed at each side of the notch m on the outer face of said lock-bolt stem fora purpose hereinafter explained.

O is a rectangular notch on the inner lower edge of the lock-bolt stem, designed to engage the projecting lug 49 of the cylinderlock case when said cylinder-lock is operated. I 44 is a slide let into the opening 42 of the fixed wall of the lock-case.

The lock-bolt stem has two pins or studs, 8 one on its upper edge and one on its lower edge proj ecting toward the removable wall. of

the look-case. Said pins engage the slots of the fence 7. v

18 is a cleft-stud secured to the stem of the lock-bolt, providing a seat for a flat spring, 18 the outer or free end of which engages a lug, 18 on the outer edge of the fence, said spring forcing the bent end 6 of the fence 7 into the recess 5 on the latch-bolt stem when the lock is operated upon by the revolvingcylinder lock.

WVhenthe lock-bolt is operated by a spindle in the squared opening of the hub 32, the fence'7 is dispensed with.

Upon the inner face of the stem of the lockbolt 18 is pivoted a lever, 20, on the upper stud, 8 said lever being provided at its outer en d with a rounded dog, 21, which enters a curved notch, 22, at the junction of the long and short arms 23 and2jt of an angle-lever, 25 Angle-lever 25is pivoted on a pin or a stud, 27, entering a perforation, 26, in the lock-bolt stem immediately in the rear of the shoulder or head P of the lock-bolt.

A flat spring, 17, has one of its ends secured in a recess in the lower edge of the lever 20, the outer or free end bearing against the up per edge of the arm 24 of the angle-lever 25. This spring normally presses the angle-lever 25 against the stud 30 and the lever 20 against the hub.32, said hub being provided at diametricallyopposite sides with the radial arms a n the arms a being located above and shorter than the arms n.

43 is a threaded rod passing through asuitable opening in the lug 45, said lug being cast integral with the fixed wall of the lockcase and acts as a bearing for the rod a3.

41 is a slide seated in the opening 42 of the fixed wall of the lock-case, said slide having a threaded opening in. which one end of the rod 43 is screwed. i7 is a forked plate which engages the encircling groove 46 on the rod i3. This forked plate is designed'to lock the rod 43 when the cylinder-lock is seated in the opening y, and prevents the accidental removal of said cylinder-lock from its seat. This rod is designed to force the slide ii against a shoulder on the cylinderlock and secure it in the openingy of the said wall of the mortisedock.

The operation of the mortise-lock without against the arm 23 of the angle-lever 25, which frees the arm 24 from the pin 30 and enables the lock-bolt to be projected. \Vhen the lock-bolt arrives at the end of its travel, the spring 11 forces the elliptical pin 19 on the lever 11 into IIO the recess 23, forcing the slotted flanged lever 8 up, and causes the flange 9 to pass back of the latch-bolt stem, thus locking said latch-bolt. Immediately after the pin 19 comes in contact with the arm :23 of the angle-lever 25 the spring 17 forces the notch 28 011 the arm 24: against the stud 30. To unlock the lock-bolt, turn the spindle in the opposite direction from that used in locking it. The arms a on the hub 32 cause the rounded do 21 of the lever 20 to bear against the upper edge of the rounded notch 22, which movement causes the arm to force the elliptical pin 19 out of the recess 23, at the same time withdrawing the flange 9 of the lever 8 from engagement with the latch-bolt stem. By continuing to turn the hub 32 the lock-bolt can be rei I'ZICtQii.

Having described my invention, what I claim isl. The combination, with the lock-case, lockbolt and latch-bolt, and operating-cylinder, ot the slotted sliding fence connecting said lockbolt and latch-bolt and governing the movements thereof, whereby said bolts are operated simultaneously as well as indepeinlent-ly, substantially as specified 2. The combination, with the lock-case pro \ided with a stud, 30, engaging a loclebolt having a spring-actuated notched angle-lever, a latch-bolt provided with a slot or guideway,

and a shouldered stud, R, on the lock-case, of a slotted sliding fence adapted to engage a recess of the latch-bolt, and a cylinder-lock mechanism for rotating the sliding fence, substantially as specified.

3. The combination, with the loclecase, of the slotted and notched loclebolt, the pivoted and notched angle-lever resting against the stem of the loclebolt, the spring-actuated 1ever having the rounded dog engaging the notched angle-lever on the stem of the lockbolt, the pivoted slotted lever having the flange or stop at its inner end, the latch-bolt having the slotted branched stem engaging the shouldered stud on the inner one of the parallel ribs, the ln'anohed and slotted slide resting on the stem of the latch-bolt, the pivoted lever provided with pins at its ends and engaging the notched angle-lever, and the pivoted lever connected with flanged and slotted stop-lever, the slotted and shouldered sliding fence, and the armed hubs for operating the latch-bolt and lock-bolt, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
