HENRY W. RAYMOND, OE DETROIT, MICHIGAN, ASSIGNOR T0 BEALS & SELKIRK TRUNK COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

TRUNK-LOCK.

Specification of Letters Patent. Patented Dec. 18, 191 '7.

Application filed August 14, 1916. Serial No. 114,772.

Be it known that I, HENRY RAYMOND, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Trunk-Locks, of which the following i a specification, reference being had therein to the accompanying drawings.

This invention relates to trunk locks and refers more particularly to a construction adapted for use on what is known as wardrobe trunks.

Among the objects of the invention are to provide a new and improved construction for locking the trunk at a plurality of place on the inside from a lock operable on the outside of the trunk; to provide a construction in which the locking mechanism will serve to draw the sections of the trunk together when being locked and can also be used for positively forcing the sections apart when the lock is turned to operate the locking bar; to provide an improved construction of locking bar and operating connection between such bar and the lever; and in general to provide an improved and simplified construction of the character above referred to.

The invention further resides in such details of construction and arrangements and combinations of parts as will more fully hereinafter appear.

In the drawings,

Figure 1 is a erspective view of a trunk embodying my invention;

Figs. 2 and 3 are side elevational views showing slightly modified constructions of operating mechanism;

Fig. 4 is a detailed view of the lock and bolt detached.

Describing in detail the construction shown in the drawings, A and B designate the sections of the trunk which are secured together at one edge by hinges C, C and C The opposite meeting edges of the two sections are secured together by a locking mechanism, the construction and arrangement of which is the main feature of the present invention.

In trunks of the wardrobe type, the trunk is generally positioned on one end at the time it is opened, in contra-distinction to the ordinary type of trunk in which the lid is lifted. Heretofore with wardrobe 'Fig. l, D designates the lock and E the keeper within which the projecting ends of the lock can be turned in the usual manner. The lock D is locked near one end of the trunk and is carried by, what in effect, amounts to a lever or rock arm F pivotally secured to the trunk at (in. As shown in Fig. 4, the bolt G has a rectangular shoulder G which causes it to rotate with the lever F and also has a rectangular end Gr upon which there is secured a pinion I-I,

although it is obvious that any other well known securing means can be employed for connecting these parts to rotate together. The pinion H meshes with the rack bar J which is mounted on the inner face of the trunk wall by guides K and K which will permit the longitudinal movement of this rack bar.

A suitable number of locking members L are carried by the rack bar, each of these locking members being provided with slots M, which when the bar is adjusted to looking position, will engage corresponding hooks N secured to the other section of the trunk. It will be noticed that these slots are so arranged that the walls 0 and 0' form inclined surfaces. In closing the trunk, the lever F is turned until it is positioned at substantially right angles to the rack bar J, and the pinion G acting on the rack will force the bar J downward, causing the inclined surface 0 to ride down over the end of the securing hook. only lock the sections together, but the inclined surface 0 serves as a cam for automatically forcing the sections together. When thus positioned, the two sections are drawn tightly together and locked both by the members L and the lock D. In unlocking the trunk, the lock D is disengaged from its keeper E by a key or the like, after which the lever F is turned to adjust the rack bar upward. This not only withdraws the in clined surface 0 out of locking engagement with the hooks N, but the inclined surface 0 acting as a cam against the surface N This will not,

of the hooks will positively force the two sections apart.

While in Fig. 1, I have shown a rack and pinion for operating the bar which carries the locking members, other mechanism for transferring rotary into longitudinal movement can be employed within the scope of my invention. In Fig. 2, I have shown a rock arm P and link P for accomplishing this purpose, while in Fig. 3 there is employed a rock arm Q having a slot Q, through which a pin R on the longitudinally-adjustable bar extends.

It will be noticed that the locking members. L are so constructed that at the end of the inclined walls O and 0 there is a short slot S which extends substantially parallel with the direction of movement of the rack bar. Therefore when the latter is adjusted faces,while this arrangement in no way in terferes with the positive forcing of the sections apart when the rack bar is adjusted to unlocked position.

The invention, however, is not limited to the particular constructions shown for accomplishing the movement of the locking bar or the details of construction except as specified in the appended claim.

What I claim as my invention is:

In a trunk, the combination with sections, of means for locking said sections together comprising a longitudinally-adjustable bar carried by one of said sections, a hook member carried by the other of said sections and a locking member for engaging said hook member having an inclined'slot terminating in a second slot substantially parallel to the movement of said bar.

In testimony whereof I alfix my signature.

HENRY W. RAYMOND.
