' Claims. (o -29H); i

I My invention relates to improvements in locks for use inconnection with doors or the like, and has for an object the provision of an improved construction of this character provided with im=- 5 proved means for securing the door in closed'position'and'making the samefast with'the door frame against opening movement.

One object of the invention is to provide an improved lock having features of adjustability, '10 adapting it to be used with different styles or types of doors, irrespective of theiri'ndividua'l thickness or particular mode of mounting;

Another object is to provide a device which, 7 when the door is to be secured, may be quickly applied thereto without the use of tools or the like, and which may be laid aside or stored away when it is not to be used for securing the door. An advantage of my invention is thatit maybe used by travelers or other persons for'secu'rely fasteningthe door of a temporary or, strange abode. 1

A further object'is to provide a simple and practical lock construction of the character described'which is capable of use in connection with eithera'left-hand or a right-hand door.

With the foregoingandother objects in view, the invention consists in the novel construction, combination and arrangementof parts hereinafter more fuily'described with reference to the simple and practical exampleillustratedfin the accompanying drawing, in which H Figure-1 represents atop plan view of a lock made in accordance with my invention, the same being shown in connection with fragmentaryporr- 'tions of a door and door frame shown in dashdot outline; and v Fig. 2 represents a side elevation of my device, with one side of the casing removed in order to exhibit the interior parts and cooperation thereof.

' The invention isherein describe'd'a's embodied in a door lock, but it is equally applicableto fdesk drawers, filing cabinets anda large variety of uses. '45 Referring with more particularity :to; the accompanying drawing, it will be seen that the lockof my invention is represented as comprising two slidably associated devices. consisting of a support *in' the form of snack bar '3 and a fixture in the form of a casing denoted in' general by the reference) character 4 and which" consists ofa rectangular box-like body Sf'and a side or cover 'G -ior the same. As" herein represented, said.

side or cover 6 is securedto the box-like body bymeans of rivets Iwhich, after being'passed transversely through the cover, are engaged with openings 8 suitably provided for the purpose in the body part 5, and then upset. The box-like casing then becomes permanently closed, in a manner thatit cannot be opened except by de- 50 struction thereof. I

Adjacent one end, the body part 5 is provided with a channel 9 in which the rack bar is slidably disposed, 'it'being noted that said channel 9 is provided entirely through the opposite sides'of the body parti-or the projection of the rack bar in b'ot-h -directions from the body-part. As will beseen from Fig. 1, the cover 6, when applied to the body part; serves as means whereby to retain the rack bar slidably in place. By this arrangev ment, the" rack bar serves as a support for the fixture or casing 4 which can be readily moved or slid along the length of the rack bar. Qne end of the rack bar is formed with an over-bent portion-or hook '10 adapted, when the device is applied in a position in which it will come between the-free edge 11 of the door 12 and theadjacen-t' door frame l3, to be engaged with the usual latch receiving fitting or keeper l4 custom'ari-ly found in a door frame. The body part 5 is formed with a lateral projection or abutment 15 adapted to engage the face 16 of the door, and it will be noted; that thisabu-tment 15 projects from the casing in a direction opposite to that in which the hook'l'd extends, so that when the hook is applied to the keeper and-the door closed, the casing may be moved-along the rack bar until the abutment engages the face 16 of the door.

Thejbod-y part 5 is formed with a chamber 17 "which is in open'communication at 18 with the channel -9', and along its longitudinal edge 19 the rack bar is provided with :a seriesof teeth 20,

adjacent the opening 18, where to be accessible for engagement bylocking means operatively arranged in the chamber 17. In the present embodiment, the locking means is represented as comprising a-looking 'lev'er made in the form of a bell-crank 21 and an operating lever 22 which projects througha suitable opening 23 so as to 'beoperated' from the exterior of the casing. The

levers 21 and 22 arepi-votally mounted within the chamber 17,- the former being mounted upon a s-tud'24 and the latter upon a stud 25. The long arm of the bell-crank lever 21 is provided with projecting teeth 26 adapted to interlock with the teeth 20"'of'therack bar. The lever 22 is provided with a contact end 27, and this lever is so pivoted with respect to the bell-crank that the contact end 27 will be adapted, upon moving the lever 22 intoits dash-dot position 28 as shown in Fig. 2, to engage the short arm of the bell-crank and move the bell-crank in a direction to effect disengagement of the teeth 26 from the teeth 20 whereby to release the rack bar; and also so that when the lever 22 is moved reversely or into its full-line position, said contact end 27 will engage the long arm of the bell-crank and force the'latter into that positionin whichthe teeth 26 will engage the teeth 20 thereby locking the casing and rack bar together. In this connection it will be observed that the lever 22 is so arranged'a'nd its contact end 27 so formed that when this leveroccupies its full line position, its contact end 27 will firmly maintain the bell-crank inthat position in which its teeth 26 are interlocked with the teeth 20.

as at 30 for receiving suitable locking means such as the hasp 31 of a pad-lock 32. of the casing is provided with a projectinglug 32' also suitably apertured (aperture not shown) for receiving the hasp 31; andthese parts are so arranged that when the lever 22 is moved into its full line position, its aperture. 30 will register'with the aperture of the lug 32 to enable the hasp of the pad-lock to be passed through the apertures of both the lever and the lug whereby to secure the lever to the lug and thereby prevent any reverse movement of the lever such as will permit disengagement of the teeth 26 from the teeth 20.

In the use of. my device,the casing is slid along the rack bar in a direction away from the hook 10 so that the rack bar may be applied against the door frame and the hook engaged in the keeper l4, whereupon thedoor is closed and the casing slid forwardly along the rack bar until the abutment 15 engages the face 16 of the door, when the operating lever 22 is moved to its full line position so as to move the bell-crank into interlocking engagement with the rack bar thereby securing the casing and rack bar together in that position in which the abutment engages the door. The pad-lockBZ or other suitable device is then applied so that the operating lever cannot be moved reversely.

The device of my invention is adapted to be used in connection with either a right-hand door or a left-hand door since the hook 10 and the abutment 15 project in opposite directions for engaging respectively the keeper in the door frame and that face of the door which comes at the inside of the room. It will be recognized, from this arrangement, that in order to change from a right-hand door to a left-hand door it is only necessary to invert the entire device.. Where desired, the rack bar may be permanently attached to thedoor frame by means of a screw or the like which is entered in theopening 33 of the rack bar and engaged with the door frame, the saidopening 33 being suitablycountersunk for receiving the head of the screw so'as not to interfere with the closing of the door, I

While I have illustrated and described in detail the preferred form of construction for carrying .my invention into efiect, this is capable of -vari- .avail myself of such variations andmodifications as come within the scope of the appended claims.
