To all whom it may concern." i y Y Be it known tliatvl, CHARLESFLIBERMAN, a citizen `oit' kthe United States, residing at New York, in thecountyot` New Yorkand State ot New` York, have invented certain new and useful Improvements in`Multiplelfollowing to be a full, clear, andexact description of the invention, such as vwill enable others skilled in the art to which it appertains to make and usethesame. i

This invention relates to new and useful improvements in multiple bolt locks, and

thexprincipal `object of the invention is to provide anovel means for actuating a plurality of bolts of a lock simultaneously.

`Another object or' this invention is to provide a lock and casing l`for the lock whereby it may be readilyand quickly attached to a door `with little eort on thepart ofthe person applying the same. .y i

A still further object of the invention is `to provide an eiicient and simple lock, capableof being readily operated andfalso being of such construction as t0 be v'easily an cheaply manufactured and' assembled.

A still further object of this invention is to provide a simple,kpractical, and comparatively inexpensive structure, which `maybe easily assembledyand applied to use.

With these and other objects in view, the

invention consists inthe novel `combination and arrangement of parts hereinafter `more fully described and pointed out in the claims hereto appended. i y

Referring more particularly toy l ings by the characters of reference, theinumeral` 1 designates the casinginiits `entirety which` is embedded in adoor.` The casing 1 comprlsesin its constructionthel` rearwall y2, sidegwalls3 ande, and theftopiand-bot`` `tom walls 5 and 6, and thepartition `wall .6 whlch divides the casing in two Chambers 7 and 8..

The casing is providedatftheforward `edges of the top and bottom wallswith fthe attaching members 7 and 8,- which members are arranged 1 at l right angles to the ltop and bottom `walls and are provided'` with` the` 4openings 9 in which arethe screwslO which securethe casing 1 to the faceplate 11. i i t The face plate 111 is `'provided nearyits upper and lower ends with the end bolt casings 12 and 1 3 in .which are slidably'pmounted the end bolts 14:y and l5.` Thewwallslof theendcasings are provided with elongated slots 16 and 17 throughwhich extends Athe upper ends of the links 18 andn 19., LThe ends of the links are pivotall'y connectedto the rear ends of the bolts 14C and leas at 20.

` `The inner ends of the end boltsare slotted and provided with transversely extending pins 21 to which are pivotallysecuredpthe ends of the links 18 `and 19.

Slidably mounted in the chamber 7 .is` the central bolt 22 which is supported on the dit.

U-shaped frame 23. One 311,11. oftheframe `23 is provided with" a recess 24 having one lof its-walls inclined as at 25. ThereceSS ls adapted to receive one endy of the. key actuatf ing bar 26 therein,` which baris pivotally mounted centrally inthe side walls ,3 and `4l of the casing 1. The key actuating barr2h6 is provided centrally with` a rectangular lug 27 which extends through one `sidewallloi: the casingand is designed to be rengagedkby thekey to rotate the actuating bar to move the bolts into a locked or unlocked position.

Slidable laterally withinthe casing land upon the frame 23 are the plates 28-1and29, having.` their opposededges cutaway as at 30. Formed integrally with the front edges of the v.plates V28- and 29;are the rodsw32, which rods have their free ends extending in the direction of the end bolt casing carried by the face plate.

The rods 32 are provided intermediate their ends with guide slots 33, through which pass the screws 34. The screws 34 pass through the slots 33 and have their in- 1ra l `ner ends littednin'the face plate vll to holdl therads against lateral movement. .Selilelv te 'uns ends of the-reds 32 the strap-s' 35.;

3. A bolt of the class described comprising a plate, a rectangular casing removably secured to one face of the plate centrally thereof, circular casings' secured adjacent each endA of said plate, a U-shaped frame slidably mounted iii said central casing, a locking bolt carried by the web of said frame and extending out through said plate, locking vbolts rslidably mounted in each of the casings near the ends of the plates', a pair of vvplates slidably mounted in the casings and arranged upon the first named plates, rods having one end connected to the forward ends of the last named plates, links connecting the ends of said rods with the bolts inthe end casings, operating means located in the central c'asingand secured to Y the plate, and means for operating the operating means for moving the bolts and plates simultaneously.
