LATGH.

SPECIFICATION f ormng part of Letters Patent No. &50,290, dated Aprl 14, 1891. Application filed November 21, 1890. Serial No. 372,237. (No model.)

To all whom 't may conccrn:

Be it known that I, J ULIUS XV. HANSEN, a citizen of the United States, residing at Humphrey, in the county ot' Platte and State of Nebraska, have invented a new and useful Door-Lock, of which the following is a specication.

This invention has relatiou to door-looks; and the objects of the invention are to provide an improved lock of cheap and simple Construction adapted to be applied to doors and to be operated without rotating the knobs, thereby avoiding all looseness of the same, and to provide means for looking the bolt upon the inside without the use of the key and in such a way as to be inoperative in connection with the door-knob.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

i Referring to the drawings, Figure 1 is a perspective of a lock constructed in accordance with my invention, the same being secured to a door. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a horizontal section. Fig. 4 is a detail in side elevation of the knob located at the outside of the door.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates a door f'ame or casing, and 2 the door, both of ordinary construction, and to the former there is Secured upon the inner side thereof akeeper 3 by means of a screw4.

5 designates thelock-case, secured to the inner side of the door 2 opposite the keeper 3 by means of screws G.

In partitions 7 located in the lock-case, there is mounted for reciprocation a bolt S, having the usual chamfered outer end, reduced rear end 9 between the partitions, and in front of said reduced end or near its middle provided with a recess lO in its upper face. A coiled spring ll encirclcs the reduced portion 9 of the bolt between the rear partition and the shoulder upon the bolt caused by such reduction, and serves to nornally project the bolt for engagement with the keeper.

The outer end of the lock-case is provided with a slot 12, and in the same is mounted the shank of'a button 13, connected to which within the case is a block or tumble'r 14. By op-` erating the button 13 within the slot the tumbler maybe moved in rear of the bolt and in the path of the same, whereby said bolt 'cannotbe reciprocated so as to disengage with the keeper.

From the opposite faces of the lock project laterally hollow studs 15, that stud located next the door being longer than the inner stud and projecting a slight distance beyond the door. The studs are located opposite the recess 10 of the bolt 8 when the latter is shot, and are provided at their inner ends with recesses lG, which terminate or are continued in the form of hollow bores 17.

18 designates ordinary door-knobs, with the eXception that they terminate at their inner ends inperforated securing-fianges19, through which are passed screws 20 for securing them in position. The bores 17 of the studs are continuedin bores 21 in the knobs, and in the bores 20, 21, and 16 are located rods 22, which have their outerends threaded to receive buttons or disks 23, centrally perforated to engage with the rods. The rods extend into the lock-case, are bifurcated at their inner ends, and are preferably provided between their bifurcations with small rollers 24:. Collars ,25 are formed on the rods, and said rods are provided with slots 26 near their inner ends, through which and the shanks of the knobs are passed screws 27, whereby said' rods are prevented from rotation and are limited in their reciprocations. Upon each rod, between its fiange 25 and screw 27, is coiled a light spring 28, which normally presses the rod outwardly.

Through the bolt S is passed a bearing-pin 29 a'slight distance in rear of the middle of the recess 10 in said bolt, and upon said pin within the 'ecess 10 there is mounted loosely a disk or roller 30, against which the inner ends or rollers 2& of the rods ride.

The operation of my lock is as follows: To disengage the bolt from its keeper from either side, it is simply necessary to grasp the knob 18, in which position the button 23 will be in the palm of the hand. By exerting a gentle pressure toward the knob the rod is forced within the same against the tendcncy of its spring 28, and its inner end, at which is located the loose roller 24:, is brought in contact with the disk or roller 30, and, being iocated in front of the transverse center of the same, i serves to force the disk to the rear against the spring 11, and thus reciprocates the bolt until the same is out of en gagement with the keeper. In closing, the bolt engages the keeper after the ordinary manner. It Will be observed that by moving the button and its tumbler to the outer end of the slot in which it is located said tunbler will be projected directly into the path ot' the bolt S, and thus the latter is locked against a retraction by means of the knobs.

It will be observed that the above-described lock may be'operated without the key and without the necessity of a special lockingbolt, and that no knobs are loosely connected with the lock, and theret'ore iiable to become loose and worthless.

Having described my nvention, what I claim is l. Theconibinatiomwith theiock-oase having the reciprocating bolt, a spring for throwing the bolt, and a rotatable roller mounted upon the bolt, of hollow studs projecting from the lock-case at one side of the center ofthe roller, opposite rigid knobs mounted on the studs, rods mounted loosely in the studs and knobs, terminatin g at their outer ends in disks and having their inner ends slotted, springs for throwing the rods outwardly, roilersi nounted on the inner ends ot" the rods and l adapted to operate against the face of the roller ot' the bolt, and transverse pins passed through the hoilow studs and slots of the rods, sn bstantially as specified.

2. The combination, with the case having partitions, the boltmounted therein and adapted to reciprocate, said bolt being provided upon its upper face with a recess and terminating in a reduced end, a spring coiled about the reduced end between the rear partition and the end of the bolt,a pin passed through the recess, and a loose roller mounted thereon, of opposite studs extending from the casing provided with recesses at their inner ends and continued by hollow bores, knobs nounted on the studs and rigidly secured to the door and casing and provided with continuations of the bores, rods nounted in the bores and having buttons or disks threaded on their outer ends, provided near their inner ends with collars, below the same With slots, and at their extremities bifurcated, roilers mounted in the bifurcations, screws passed through the studs and the slots of the rods, and coiled springs encirclingthe rods between the screws and collars, substantially as specified.

in testimony that I claim the foregoing as my own I have hereto affixed my signature in presence ot' two witnesses.
