Application illed )hy 27, 1908. Serial No. 436,215.

To all whoml it may concern:

Be it known that I, ROBERT W. KING, a citizen of the United States, residing at Syracuse, inthe county of Onondaga and State of New York, have invented certain new and useful Im rovements in.Trunk-Loeks, of which the ollowing is a specification.

This invention relates to improvements in lock mechanisms, designed for use in connection with trunks, chests and the like, and theinvention relates particularlyT to a locking mechanism having a plurality of locks connected and operated as one part.

The oli`ect of this invention is to provide a lock mec anism for use on trunks, eases or doors, which is sim le, effective, strong and inexpensive, and wllierein the construction and arrangement of the parts are such that a trunk-lid or a door may be readily and sccurely locked, or unlocked at several difler,

ent points at the sal'ne time. A 'further object of the invention ist eliminate the auxiliary movable catehesvor latches usually employed on the outside of 'trunks .and similar cases and co eratin with the main lock for holding the li close and to substitute therefor a series of power'- fiil blind auxiliary locks or latches disposed on the inside, and a series of fixed plates on the outside of the trunk.

A further object of the invention is' to provide a lock mechanism having a plurality of locking,r inciiibers or parts, capable -of being operated simultaneously to lock or unlock a lid, door or other movable part at different points, wherein the arrangement of the parts of cach iI'iflividuai-I lock is such that, one or more of the locks ma be brokeiii or iiiipaii ed without rendering tie remainingr partsv iiiefl'ective';

A further object' of the iiivei'ition. is to provide a plurality of locking;r mechanisms, dis

The invention consists principally of a moin lookin mechanism comprisin a pivoted s iiing-asp or like pal-t to whic i is connecte a lock controlled by a key, the main locking arts preferably disposed on the outside of t 1e body of a case or door in position to afford ready access tothe same.

The invention further consists of one or more auxiliary bolts of peculiar and novel construction, which are preferably disposed inside of a trunk or door, at soine distance from the main lock, the said bolts being eperatively connected with the pivoted lia-sp, for the purpose of releasinfy them simultaneousl y, after the main lock Tias 'been released. The said auxiliary bolts also capable of. being set in locked position automatically without the co )eration of the main lock. Each of said bo t-locks comprisinv' a female member attached to the body ci? the ease, a male member connected to the lid of the case, and a s rin controlled reeiprocatin bolt or latc to iold said members interloc ed.

The invention further consists of means for connecting Athe bolts with-the pivoted hasp of the main lock, by means of which the sai( bolts may be operated simultaneously, in the direction to unlock the cover or lid, from the outside ofthe case.

and also the key 24 comprise parts of a wellknowntrunk or chest lock in common use, the detail description of which are not material to the present invention, as any suitable form of lock may [be employed 1n connection with the hasp 2 for carrying out the plate4 Iis depressed centrally in a .manner similar to plate 3, to form a c llndrical cup in a erforation or mortise 27 formed in the lid The to re ister with the perforation 28.

lin Fig. 13, and then by turning the key a f bottom or inner wall of the socket 26 is pro- L vided with an oval perforation 28, through which catch 23 of the main lock is adapted to 'have free passage. Catch 23 is formed to correspond with perforation 28, and to lock and unlock hasp 2, it is only necessary to operate the key a quarter-of a turn, which will rotate the latch to the `osition shown by idotted lines in Figs. 2 an 11. The full lines in said figures show catch 23 in 'unlocked position and registering with the perforation 28.

' In practice when the operator manipulates the key 24 and'shifts catch 23 to the position last described, the spring 2() will disen age lthe upper end of the hasp 2 from the acelock the trun 'or case the o erator should' first insert or take hold of t e key 24 and turn it suiiiciently to set catch 23in position He shoul then press the hasp inwardly against the tension of spring 20 until the has .enters and lies in the recess 7, as shown by: iulllines quarter turn .catch 23 will beishifted or rotated to the )osition shown. by dotted lines in Fig. 11 which will elect the locking of the lid and case. The relation of catch 23 and hole 28 are such, that after the hasp and lock 21 have been inserted inthe socket 26 and key 24 operated a uarter turn, catch 23 is ythereby rotated to iorizontal position, as shown by dotted lines in litigs. 2 and` 1], which cil'ccts' the locking of the lid in closed posi' tion.
