LOCK- SPECIFICATION forming? part of Letters Patent No. 567,063, dated september 1,1896.
Appncatibnneanay',1896. smart. 590,430. om man T0 @ZZ whom it may concern:
Beit known that I, JOHN ALFORSf Hanna, A
in the county of Carbon and State of Wyoming, have invented a 'new and useful Improvement in Locks, of which the following is a full, clear, and exact description.YY
The object of my invention is to provide a lock adapted for use upon doors,` drawers, or wherever an ordinary lock may be employed, in which lock the knobs willy be static'narily attached to the casing, a key being employed for returning or unlocking the bolt, which key is introduced into either` of the knobs instead of into the body of the lock, as is cus-` tomary; and a further object of the invention is to so construct the lock that when the key is withdrawn therefrom the bolt of the lock will automatically assume and maintain a locked position, thereby insuring the lock-` ing of the door or other article to which the lock is applied before the key'can be placed in the pocket or stored away.
The invention consists'in thernovel construction and combination of the several parts, as Will be hereinafter' fully set forth, and pointed out in the 'claims'.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts 'in all the figures.
Figure 1 is a horizontal section through a portion of a door and door-jamb and through the major portion of the improved lock applied to the said door, the keys being shown in position in the knobs. Fig. 2 is an end view of one of the knobs with the outer or cap section removed. Fig. 3 is a section taken substantially on the line 3 3 of Fig. 1. Fig. 4 is an end View of the knob with the cap-section removed, illustrating the key in position in the knob; and Fig. 5 is a perspective view of a key used in connection with the lock.
In carrying out the invention the lock is shown as secured to a door A, the jamb B of which is provided with a recess 10, partially covered by an ordinary keeper-plate 11. The
Casin g of the lock is practically T-shaped, embodying a tubular shank 12 and a tubular head or cross member 13, which is preferably of greater diameter than the shank member. The shank member of the lock-casing is placed horizontally in the door between the sides of the same, while the head member eX- tends outward,'preferably beyond both sides of the door, and the outer end of the tubular member 'of vthe casing is practically Hush with the swing edge ofthe door.
At each end of the head portion of the casing a4 knob C is rigidly secured, and each knob 'is made preferably in two sections 14 and 15, the said sections being removably connected by straps 16, attached, for example, to theinner face of the outer section 15, being secured to the inner section 14 by means of yscrews 17 or their equivalents. is held to slide in the shank portion of the casing, and the bolt is provided at its outer end with the usual latch-head 19, which, when the door is closed, extends through the keeper 11 into the'recess 10 of the door-j amb. A collar 20, formed on the bolt adjacent to its latch-head, limits the outward movement of the bolt, and the r'latch-head is held normally in locking position through the medium of a spring 21, coiled around the bolt and having bearing against the collar2O and a iiange 22, formed Within the shank portion of the casing.' The inner end 23`of the'bolt is enlarged in diameter, and the enlarged inner end or inner head 23 of the bolt extends across the head portion or member of the casing and into a central tubular extension 24, which is in alinement with the shank portion of the casing, asbest shown in Fig. 1, and a slot 25 is'diametrically made in the inner head 23 of thebolt, parallel with the head-section of the casing.
At each side of the center of the head-section of the lock-casin g preferably two parallel cross-bars 26 are secured, and between each set of cross-bars a lever is fulcrumed, the right-hand lever being designated as 28 and .the left-hand lever as 28, Both these levers extend into the recess or slot 25 of the bolt, one independent of the other, and the outer ends of the levers are carried within the knobs C. In one side of each knob an opening 29 is produced leading' into the interior, and within each knob a tube 30 is secured, open at one or at both ends, and one open end of the cas- A bolt 18 IOO ing is in register with the opening 29 in the y knob. The shape of the opening 29 and the cross-sectional shape of the tube 30 are prac- 2 sessies tically the same, being preferably7 somewhat oval, as illustrated in Fig. 8.
The tube 30 in the knob is provided upon its outer face, at the center, with a slot 3l, which extends from its outer end practically to its inner end, and a registering slot 32 is made in the inner face of the tube 30, the back slot being made ordinarily at a central point, and the outer ends of the levers 28 and 2S, when passed within the knobs, are carried through the front and the rear slots in the tubes 30 of the knobs and extend outwardly beyond the outer or front faces of the tubes.
At one side of the outer face of a knob-tube a locking-arm 33 is located, while a second locking-arm 34 is placed at the opposite side of the center of the tube, as shown in Figs. 2 and 4. Each one of these locking-arms is pivoted at its lower end to the front face of the knob-tube, and the locking-arm 33 is provided with a recess 35 in its inner edge adapted to receive and serve as a keeper for the bolt-lever, which is passed through the knobtube, while the opposite locking-arm 34 is provided with a handle 36, so bent as to form a shoulder 36, which will enter a slot 37, made in the side of the knob-tubes, as shown in Figs. 2 and 4, and the handle end of the locking-arm 34 extends outward through a slot 3S made in the knob. The arm 33 is a lockingarm for the bolt-lever, while the arm 34 is adapted to lock the key D in the knob.
The body portion of a spring 39 is preferably inade to cross the outer face of the lower portion of the knob-tube, and between the body portion of this spring and the tube the locking- arms 33 and 34 are pivoted. The ends 40 of the spring are bent upward and inward over the body and terminate in hooks or their equivalents, which engage with pins or projections 41, formed on or attached to the locking-arms and 34, the curved portions of the spring serving to normally hold the locking-arms in their locked position.
The key D comprises a head 42 and a tubular body 43, which is of corresponding crosssectional shape to that of the knob-tube the key is adapted to enter, and the key is further provided with a slot 44 in its bottom and a longitudinal rib 45 upon the central portion of its front face extending from the head to the bottom slot, while in one side of the body of the key an opening or slot 46 is made.
In operation, when a key is introduced into the tube of a knob and pressed inward, the rib 45 of the key will enter the long slot 31 in the front of the tube, and the bottom slot 44 in the key will receive the outer or projecting end of the bolt-lever contained in the knob. Therefore, when the key is pressed inward, the bolt-lever will be forced in direction of the inner end of the knob-tube, and the inner end of the bolt-lever will be forced in an inwardly direction in the slot 25 of the bolt, carrying the said bolt inward and withdrawing the latch-head from its keeper, permitting the door to be opened, and when the key is fully pressed downward in the knob the shoulder 3G of the lockingbolt 34 will enter the slot or opening 4G of the key and prevent the withdrawal of the key, and will likewise prevent the spring of the bolt acting, so that the door may be closed at any time without locking, it being understood that when the key is forced in the knob the locking- arms 33 and 34 are forced outward, so as to relieve the said arms from engagement with the bolt-lever and permit of the passage of the key. Then the key is withdrawn, the spring returns the locking-arms to their normal position, and the spring of the bolt will then act to force the bolt outward, and the door will be locked when it is closed. It will be understood that the lock may have one knob only, if so desired.
Having thus described my invention, I claim as new and desireto secure by Letters Pat-ent* l. In a lock, the combination, with a casing, a spring-controlled bolt held to slide in the casing, a fixed hollow knob, a tube located in the said knob and communicating with its exterior, the said tube being provided with an opening in the front and in the back, a lever fnlcrumed in the casing, one end of 'which lever enters the bolt the other end being passed through the slots in the knob-tube, and spring-controlled locking-arms located at opposite sides of the knob-tube, one arm entering the tube and the other being adapted for locking engagement with the bolt-lever, of a key shaped to slide in the said tube, having a recess in its lower end to receive the said bolt-lever, and being also provided with a rib which extends through the slot in one face of the knobtube, and a side opening adapted to receive the locking-arm which extends within the said tube, the said lockingarm being operative from the exterior of the knob in which the lock is located, as and for the purpose speciiied.
