TRUNK-LOCKING MECHANISM.

Specification of Letters Pate at. I

Patented Feb. 22, 1916.

Application filed October 25, 1915. Serial No. 57,664.

To all whom 2'? may concern:

Be it known that we, GEORGE F. Gnonn and JULIUS V. .Mnynnlno, citizens of the United States, the 'i'ormer a residentot Evanston, Cook county, Illinois, and the latter of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Trunk Locking lliechanism, of

which the following is declared to be a full,

' by a movable locking member, located. on the outside of the trunk or other object, thereby dispensing with catches or locks at various places on the outside of the trunk, which catches must be operated individually in fastening the two hal vcs of the trunk together.

Other objects are to simplify locking mechanism of this class, and to strengthen and otherwise increase the eliicieucy thereof, and with all of said objects and advantages in view this invention consists in the several novel features of construction, arrangemonk and combination of parts hereinafter described and claimed.

The invention is clearly illustrated in the accompanying drawing, in which: 7

lfigure 1,,is a vertical section through a trunk, showing in side elevation, a trunk locking mechanism embodying a simple form of the present inventioh, in locked position, applied thereto; Fig. 2, is a side View of the same parts, with portions of the trunk body broken away, the locking mechanism being shown in unlocked position and the two trunk sections partly opened; Fig. 3, is a side elevation of'a fragment of the trunk, showing the outer locking members; Fig. 4, is a detail, horizontal section taken on line ll, Fig. 1; Fig. 5, is a detail, horizontal section taken on line 5-5, Fig. 1; Fig. 6, is a perspective View of a lock bar shifting member and Fig. '7, is a side elevation of a. slightly modified form of lock bar shifting means.

Referring first to Figs. 1, to 6, inclusive of said drawing, which illustrate the preferred embodiment of theinvention, 10,11, indicate the two sections or members of a trunk, hinged together as usual, and capable of containing many of the common and well-known compartment devices and other apparatus; for receiving clothes and other baggage. Near one end or the meeting edges 12, 13, of the two sections is the outer locking mechanism 14:, which may comprise the usual hasp member 15, mounted on one section and socket member 16,-

mounted on the other section and adapted for locking engagement with said hasp member in accordance with the common and well-known practice. In the form shown,

the hasp member 15, has a hinge joint at 17,

whereby the hinged part. mayswing toward and away from the socket member in looking or unlocking the'trunli, and said hasp member 15, is pivotally, mounted on: the trunk section 11, on a horizontal .piyot, whereby it may be swung-upward from the position shown in full lines in Fig. 3, to that shown in. dotted lines and Vice Verse, for the purpose of actuating the internal locking mechanism. Conveniently the hasp memberjhas an inwardly extending pin or bolt 18, rigidly secured thereto and projecting through an opening in the trunk section and turning freely therein. The innor end of said pin or bolt 18, is squared, f

and rigidly secured to said squared cnd'is a segmental rack 19, the teeth of which mesh with teeth 20, on a lock bar 21, which is slidably mounted on the inside of the trunk section 11. In the form illustrated, said teeth 20, are formed in said lock bar 21, near one end thereofland the segmental rack has two fiat sides 22, 23, arranged at rightangles to each other and adapted to strike against the adjacent toothed edge of the lock bar, to thereby limit the movement of said bar, and hasp member in either direction, the parts being so proportioned that movement of the hasp member through an arc of degrees shifts the lock bar 21 through the necessary distance to lock or unlock. the internal locking mechanism. The lock bar is guided to move in a lengthwise direction by straps 9.5, secured to the trunk section 11 and overhanging the bar. On the adjacent side opposite trunk section 10, are fastened a plurality of stationary or fixedly secured internal lock members 25,

which project across the meeting edges of the two trunksections and are arranged for locking engagement with the sliding lock bar 21. In the form shown said internal lock members 26, are formed with notches 27, in their upper edges, near their outer ends, adapted to receive lock bolts or lugs 28, carried by, and preferably formed integral with the sliding lock bar 21. Con veniently the notches 27, have inclined edges 29 inclined upwardly and outwardly, and the lock bolts or lugs, 28, have similarly inclined edges 30, adapted for engagement with and coacting with said inclined edges of the notches 2'7, to force the two trunk sections together. At the upper ends of the inclined edge portions are upstanding lugs 31, which are adapted to engage With straight edges on the rear sides of the lock bolts or lugs 28, whereby when the parts are in locked position said straight edges engage each other and positively prevent relative movement between the two trunk sections. When the lock bolts or lugs 28, are formed integral with the lock bar 21, notches 32, may be formed in said lock bar behind and below the lock 'bolts or lugs 28, for tllu reception of the notched ends of the inte: 121i lock members 26, and said notches 32, are made long enough to permit the lock belts or lugs 28, to be Wholly withdrawn from the notches in the internal lock members 26, as clearly illustrated in Fig. 2, where it will. be seen that said notches 32, are position registering with the ends of the internal lock members 26. In operation, the external locking mechanism is unlocked and the beep member swung into the position, indicated in dotted lines in Figs, 2, and, 3, to unlock the internal locking bar is thereby raised out of locking engage ment with the internal lock members, through the .instrumentality of the segmental rack. The two trunk sections may then be swung open. To lock the trunk the sections are swung together, and the heap member is thereafter swung down into register with the external socket member, the straight edge 22, of the segmental rack thereupon striking against the adjacent edge of the lock bar 21. The hasp member is then locked to the socket member as usual, thereby locking the two sections together at a plurality of places on its interior. The trunk cannot be unlocked said places without first unlocking the exterior locking mechanism. 1

In the modified form shown in Fig. 7, the hasp member 15- is connected to the lock bar 21 by an eccentricaily disposed pin 19*, secured in one member and projecting through a slot in the side of the trunk section and em gaging the other member, In this case the pin or bolt 18?, simply acts as the hilcrmn or 29, of the notches 27,

mechanism; the lock,

pivotal connection between the hasp member and trunk section; the lock bar and internal lock members may be constructed substantially as in the preferred form.

More or less variation of the exact details of construction shown and described is possible without departing from the spirit of this invention. We desire therefore, not to; limit ourselves to the exact forms shown and described but intend in the following claims to point out all of the invention disclosed herein.
