LATCH AND LOCK COMBINED.
SPECIFICATION forming part of Letters Patent No. 477,142, dated June 14, 1892. Application iled March 10, 1892. Serial No. 424,434:- (No model.)
To all whom it may concern.-
Be it known that I, JAMES \V. MCKEE, a citi zen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Locks, of which the following is a specification.
This invention relates to looks, and more particularly to such as are operated by the direct endwise movement of the key in distinction from those in which the key is required to be turned after it has been inserted in the keyhole.
The invention consists in certain novel devices and combinationshereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal section on the bent line 50 90, Fig. 2. Fig. 2 is a cross-section on the line y y, Fig. 1. Fig. 3 is a horizontal section on the bent line z .2, Fig. 1. Fig. 4is a longitudinal section on the line no 00, Fig. 5. Fig. 5 is a cross-section on the line 3 3 Fig. 4. Fig. 6 is a horizontal section on the line .2 .2 of Fig- 4, the lock being open. Fig. 7 is a separate view of the key, taken as it appears when in the keyhole, as shown in Fig. 5.
The head A of the lock in the present example of my invention projects upward from the lock-case B, to which it is fastened by screws 0 C, that go through the lateral extension A of the head and are screwed into the bottom of the lock-case, the construction being such that the extension A comes over a depression in the bottom of the case in which the tail end D of the bolt E slides. The belt is moved outward by a spring F, whose rear end bears against a stationary post G, that rises from the lock-case through a slot made in the bolt, in which slot the spring F is placed, the front end of said spring pressingagainst the forward end of the bolt, so as to push the front end of the bolt outward to the position shown in Figs. 1 and The head A is inclosed in the hollow post A which is rigidly connected with or made part of the usual cover A of the lock-case, the arrangement shown being such as will be suitable for a mortise-lock; but of course I do not confine myself to mortise-locks. The bolt can be moved inward, so as to open the look by pushing against the slide H, which extends through the lock-case, so as to engage the tail end D of the bolt, as is shown in Figs. 1 and 4, the slide ll moving in and out with the bolt, to which it is fastened. The bolt can belocked in its outer or inner positions by means of the locking-slide I, which carries a stop J, that is moved into the notch K, Fig. 3, made for it in the side of the tail end of the bolt when the bolt is to be locked in its inner position, as shown in Figs. 4 and 6, the said stop being moved behind the tail end of the bolt, as in Fig. 1, when it is desired to lock the bolt in its outer position. The locking-slide I is moved to its diiferent positions by means of the button K, which is fixed on a pin that works in a slot K made in the lock-case.
The head A is provided with a slot A in its upper end to receive the key of the lock, said slot terminating in a rectangular opening A, which receives the upper ends of the tumblers Lfourin number in this example, although the number may be variedand the upper end of a lever M, that turns on a pin N, that is supported in standards that rise from the extension A of the head. The tumblers are held in a raised position on the pivot N by springs P, which are fastened by one end to the respective tumblers, and are then bent back over the pivot N and their free ends braced against stationary block 0, whereby the tumblers are held up by the springs with a yielding force toward the position in which the tumblers are shown in Fig. 1, where a crossbar P from the back of the lever M extends across the backs of the tumblers into a notch P, out on each tumbler, so that the bar acts as a stop to the tumblers and causes them to be in unison with each other and with the lever M on their front faces, where they present themselves in the slot or opening A of the head. The lever M has a toe Q, that projects downward from its under side through a slot R in the extension A of the head and into a slot 1 in the tail end of the bolt.
When the key is inserted into the top of the head, it passes downward and its bottom edge strikes the ends of the tumblers and pushes them downward, so that they move across the keyhole-sl0t until their notches P are freed from the cross-bar P, which action liberates the tumblers and lever M from each other and allows the tumblers to be pushed by the key down to their lowest position, (see Fig. 4,) and allowing the notch S of the key to come in its descent down upon the projection S of lever M and turn said lever M across the keyhole-slot to the position shown in Fig. 4, where its toe Q engages the slot 1 in the tail end of the bolt and draws back the bolt to the position shown in Fig. 4,
in which position the bolt is drawn back and can be held in that state by operating the slide I as above explained. On moving the slide I so as to tree the bolt, the bolt-spring F moves the bolt outward to the position seen in Figs. 1 and 3, and the lever M and the tumblers I move or swing back to the positions shown in Fig. 1.
It will be understood that by inserting the key, Fig. 7, into the head A 'it comes in contact with the ends of the tumblers L and pushes them downward from their positions as represented in Fig. I to their positions as shown in Fig. 5, their ends being pushed downward by the key and at the same time swung forward through its opening or side notches toward the positions shown in Fig. at, the tumblers being turned upon the pivot N, so as to allow their forward ends to project through the said openings of the key and to permit the notch S of the key to press upon the forward projection S of lever M, by whichmeans the leverM is made to turn upon its pivot N and to be brought to the position shown in Fig. 4, its toe Q being made to engage the tail end of the bolt and to push the bolt back, and thereby open the lock, in which operation the front ends of the tumblers and lever M-are brought to the positions shown in Fig. 4, where they are seen projecting through the opening A of the head and through the openings in the key.
It will be observed in Fig. 1 that before the tumblers begin their movements they are partly in line with the slot A of the head and underneath the same, and that the head U of lever M is wholly on one side of said slot A As the key moves into operation the tumblers are swung forward to the position shown in Fig. 4:, and the head U of the lever M moves into the perforation V of the key, Figs. 4 and 5. WVhen the key is moved down to its unlocking position, Fig. 5, it will be noticed that the tumblers L, or rather the forked ends of said tumblers, and the end of lever M, with its head U, enter or fill up the holeV and all the notches of the key, so that the entire keyway or opening A will be filled up or cut off, as shown in Fig. 5.
From inspecting the key, Fig. 7, it will be noticed that the lateral or side notches do not correspond. In making a variety of keys said notches can be made either corresponding or not, or either side of the key may be left'plain and the other notched, or the notches may he formed along the bottom edge of the key, and in this way any variety of keys may be formed. The variety can further be increased by changing the form of the opening or depression V.
It will be noticed that the lever M swings transversely to the plane of motion of the bolt, and the simple insertion of the key is sufficient to secure the transverse motion of the lever to effect a withdrawal of the bolt, while if the lever swung, for example, in a plane parallel to the plane of travel of the bolt the key would first have to be inserted and then rotated to properly move said lever.
To prevent the lever M being pressed down or actuated independently of the tumblers, I provide a stop or locking-tongue 7, swinging on pivot or support X, and held toward the lever M and tumbler L by a suitable spring Y. This locking-tongue WV is so arranged as to sit squarely under the lever M and prevent motion of the same when the parts are in the position shown in Fig. 1; but the tumblers L are arranged to act laterally on the tongue \V, either by the tumblers having their edges in contact with the upper end of the tongue W cut inclined or by that portion of the tongue WV which comes in contact with one or more tumblers being inclined. hen, therefore, the tumblers are moved in advance of lever M, said tumblers move the tongue out of the path of the lever, Fig. 4., and allow the latter to move. On the parts being released the spring Y moves the lockingtongue back to its locking position. By having the free end of the tongue W broadened or formed into a head, as seen in Fig. 2, the ditferent portions of the head can be arranged so that one portion will come squarely into contact with lever M to lock the latter, while another portion is in inclined contact with one or more tumblers L to allow the latter to move or press the tongue aside to its releasing position.
What I claim as new, and desire to secure by Letters Patent, is
l. The combination, with a lock-case havin g a keyhole-slot and a sliding bolt arranged in the case, of a pivot-pin, a series of oscilla:
tory tumblers mounted on the pivot-pin and moved across the keyhole-slot by the insertion of the key thereinto, and an oscillatory lever mounted on the pivot-pin of the tumblers, having an arm engaging the tail end of a sliding bolt and moved by the key parallel with the tumblers across the keyhole-slot to cause the arm of the lever to retract the bolt, substantially as described.
