LOCK AND LATCH.
SPECIFICATION forming' part of Letters Patent No. 246,145, dated .August 23, 1881. Application nien April 23, resi. (Model.)
To all whom it may concern.-
Be it known that I, FRANCIS KEIL, of the city, county, and State ot' New York, have invented a new and useful Improvement in Door Locks and Latches, of which the following is a specification.
My improvements relate to the class known as front-door locks,77 in which the lockingbolt, latch and night-latch mechanismr are combined in a single case.
The invention consists in certain novel features of construction and combinations of mechanism for rendering the locks more convenient and reliable, as set forth in detail hereinafter with reference to the accompanying drawings.
In the drawings, Figure I is a face view of the lock with the cap-plate of the case removed. Fig. 2 is across-section on line ma of Fig. I, and through the latch-knobs. Fig. 3 is a transverse section on line o c of Fig. 1, and through the locking mechanism. Fig. et is a vertical section on line w fw of Fig. l. Fig. 5 is an end view ot' the cylinder-lock, and Figs. 6 to 9 cross-sections of-thc same. Figs. l0, ll, and 12 are detail'cross-sections of the nightlatch mechanism. Figs. 13 to 16 show details of the latch mechanism.
Similar letters of reference-indicate correspondin g parts.
A is the case, similar to that of an ordinary mortiselock, and containing latch-bolt a, projected by a spring, a', and the locking-bolt I).
c is the inner knob of the latch, and d the outside knob, containing the night-latch mechanism. f
B is a cylinder-lock fitted in case A, for operation at either side to move the bolt b.
I will rst describe the latch mechanism in detail with reference to Figs. 1, 2, and 4, and the detail figures, l0 to 16.
The outer knob, d, is formed with a hollow cylindrical shank, d', extending, as shown in Figs. 2 and 4, through the case A. Around the shank d', and within case A, are looserin gs ef, formed with arms ej", and engaged by the knobs for movement of the latch, as hereinafter described.
g is a middle ring, formed with shoulders or arms g, and engaged by the cylinder ot' the lock contained in knob d for withdrawal ot' the latch.
h is a yoke, held in place by and tted to slide between guides g', and engaging by one of its lugs h a lug, a4, on 'the side ot' the latchbolt a. 'Ihe rings cfg engage by their arms the lugs h of the yoke, and by apar-tial turn of either ring in either direction the latch a is moved back.
The inner knob, c, is upon a solid spindle, c', which passes through the rose c?, by which the knob is sustained, andon the inner endot' the spindle is xed a bent arm, o3, that projects through a curved slot in the lock-case and enters a recess, c3, formed in ring c. (See Fig. 16.) The ringe is upon an annulartlange that is around the opening formed in the plate' vfor the lock-cylinder, so that the ring e turns on such ilange, while the rings fg are directly upon the lock-cylinder.
The spindle d passes through a rose, d2, to and against the face-plate of the lock, and is formed at its end with a projection, L2-that extends into a recess,f2, formed in ring j', Figs. 2 and 13, the opening in the lock-case being enlarged for the play of the projection when the knob is turned. The spindle d contains the lock-cylinder t', which at its outer end has an annular Hange takin ginto a rabbet formed in the face of knob d, while at the inner end of the cylinder thereis a screw-cap, i', which, being put on after the knob and cylinder are applied to the lock-case, retains the cylinder in the knob and the knob iu thelock, for the rea-I son that the cap is larger than the internal diameter ot' ring e, and thus prevents withdrawal ofthe knob and cylinder. This construction permits the parts to be readily put together, and the knob, beingin onepiece with its spindle, cannot be removed except access is had to the inner side of the door. This' is important, as it secures valuable knobs ou street-doors from being stolen.
At the front of ring j", and between the arms of yoke h, is litt-ed a slide, 7c, having a projection, It', coinciding with a recess, k2, that is formed in the ring f. A bent lever, Z, hung on a pivot, l', takes by one end against a projection on slide k, while its other end projects through a slot in the front plate of the lock- IOO case for operation by hand to moire the slide k in connection with ringf, and thus lock the outer knob, d, so that it may not be used to move the latch, or by a reverse movement ot' the slide freel the knob. A friction-spring, l2, bearin g on slide k, retains it in either position.
Thelock contained in knob d and cylinder z' is a pin-lock, of which the cylinder m fits snugly in cylinder t', and is retained therein by a screw-pin, m', that projects through an elongated slot in the cylinder t', (see Fig. 11,) so that theinner cylinder, m, may revolve. The head of pin m entersa recess, 02,in ring g, (see Figs. 2, 4, and 14,) so as to turn said ring.
From the foregoing it will be seen that the latch a is moved by the inner knob, c, acting on ring c, by the outer knob, d, acting by the ring f, and by the cylinder m ofthe lock in the knob d acting on ringg by means ot' the screwpin m. Further, the knob d can be locked by the slide lf, and the latch can then be operated from the outside only by use of a suitablefkey to turn the cylinder m.
The mechanism of the lock part of the latch is as follows, reference being made to Figs. 2, 10, 11, and 12: The cylinder m is recessed in its middle portion, and from one end of the recess apertures extend through the inner end of the cylinder, while the outer end has a narrow key-slot, m2, for receiving a lat key. The pins a (of which there are four) extend from the key-slot to and through the inner end ot' the cylinder, and are held in place in the recess by a fixed guide-piece, m3, through which they pass. Springs n extend around the pins, between the bottom ofthe recess, and collars on the pins press the pins toward the keyslot.
At the inner end of cylinder z', next the end of cylinder m, is a block, o, fixed by a screw, n2, Figs. 2 and 10, containing four pins, o', in recesses, that also contain springs 02, that tend to project the pins. The pins coincide in position with pins n, so that they shall enter the apertures in cylinder on asallowed by the pins n, and the cylinder m is thus held against being turned except by a key of proper form, which will move back the pins n 0 and free the pins o from the cylinder m.
The mechanism in connection with the locking-bolt b is next described with reference to Figs. 1, 3, 5, 6, 7, S, and 9.
The plates of the lockcase have circular apertures, through which passes a hollow cylinder, p, that extends also through the door at each side of the lockcase,and there are-r ings. p secured to the door-faces around the ends of the cylinder. On the portion within the lockcase the cylinder p is enlarged by a sleeve, p2, that is itted at one end with a screw ring or collar, q, takin g against the outside of the caseplate, so that the cylinder p, after being inserted from the outside of the door and the ring q put on, is held securely, and cannot be loosened by careless or malicious handling. The ring q has notches, so that it may be turned by a forked key inserted in the space opened by removal of ring 19', so that the parts can be readily put in place without special skill. A screw, q', projecting from the cylinder p, takes against the inside 0f the lock-plate in opposition to ring q and enters a notch in an annular flange, q2, formed around the aperture in the lock -plate, so as to prevent the cylinder from turning, and,with the ring q, accomplish the securityjust named.
On the flange q2, and around the cylinder p, is a ring, o', having a recess that is engaged by the head of a screw, g3, which projects from the lock-cylinder hereinafter described. Ring 0' is formed with an arm,1",that extends into a slot formed in bolt b. Ona stud, T5, on the bolt b is pivoted a tumbler, r2, that engages by its end a fixed stud, r3. The inner end of this tumbler is forked,one end passing in front of the arm 0" of ring r, and the other end passing above the arm and beneath the end of a second tumbler, s, that is pivoted on the bolt. One end of tumbler s projects behind the arm t", while the other end takes over the tumbler r2, as mentioned. A spring, l9,retains the contact of tumbler r2 with stud r3.
Two dogs, s2 s2, are hung by one end to studs tixed above the bolt, so that the ends ot" the dogs may project behind the slot in the bolt and rest at opposite sides of a lug projecting from arm i" ofthe ring. j
A flat spring, s3, taking upon the upper ends of arms r2, retains their moving ends upon the arm r and serves to return ring r to its middle position in the slot. NVhen the ring is moved in one direction it first acts on the forked end of tumbler r2 and the spring-dog, and raises the tumbler free from stud r3, and then projects the bolt by pressure on the end of the slot in the bolt. At the same time the ring moves one of the dogs s2, the spring of which returns the ring to the middle position as soon as released. The reverse movement of the ring first acts on dog s2, and then on tumbler s, and the latter, in turn, acts on tumbler r2, and the ring then retracts the bolt.
It will be noticed that the ring, and consequently the turning cylinder of the lock contained in cylinder p, is returned to the normal position after each movement of the bolt, and therefore the key-slot is always retained in one position, preferably vertical. rllhis is convenient, and avoids the bad appearance of a keyslot at an angle.
The cylinder p con tains a turning cylinder c: block, t, held byr, screw q, that engages with ring r. In the cylinder t are pins t', and the cylinder p contains also a block, u, titted with spring-pins u', projecting in contact with the pins t. The outer end of cylinder t has a key-slot, t2, and the operation is the same as described in connection with the latch-lock. In addition, I provide for turning cylinder t and moving bolt b from the inside ofthe door, as follows: The end of block u extends flush with the end of cylinder p, and is formed with IOS IIO
IIS
a key-slot, u2. From the base of the slot, and at opposite sides, the block is formed with longitudinal grooves that contain spiral springs n3. In the key-slot u2 there are flat pins o, that project into the side grooves of the block and take by shoulders upon the springs as, so that the springs tend to move the pins outward. The block u is also formed with an annular groove at the base of the key-slot, in which are plates o', of segmental form, resting on the pins '0, and notched for engagement therewith. These plates o are of a width to project into slots formed in cylinder p, and thus hold the block u from being turned, and consequently hold the cylinder t so that the latter cannot be turned except when a key is used to move back the pins t' u. The pins v are held normally by the notched plates o', and are formed with recesses w, which give clearance when such recesses coincide with thenotchesin plates c. This position is obtained by insertion of the key, and the recesses should be placed so that the same key serves for both inside and outside use. The block u being turned carries the cylinder t with it, and the bolt b is thus operated. l
The combined latch and lock above described meets all the conditions required in a streetdoor lock. It is of durable construction, not liable to get out of order, and furnishes the security of a tumbler-lock in connection with the latch as well as the bolt.
Having thus fully described my invention, I cla-im as new and desire to secure by Letters Patentl. The combination of latch a, yoke h, knob c, and spindle provided with arm c', ring e, formed with arms e', knob d, spindle d', with its projection, and ringf, having armsf, substantially as shown and described, for operation as specitied.
2. The slide 7s, bent lever I, recessed ring f, knob d, spindle d', and cylinder t', containing lock mechanism for operating the latch, substantially as shown and described, combined for operation as specified.
3. The knob d and hollow spindle d', formed integral, the loclecylinder i, and screw-cap t, combined with the lock-case A, substantially as shown and described.
4. The ring g, formed with shoulders g', lockcylinder t', and turning cylinder m, provided with screw m', combined with the hollow knobspindle d', with its projection, ring f, latch a, and yoke h, substantially as shown and described, for operation of the latch, as set forth.
