TRUNK LOCK'.

Application led February 6, 1922. Serial No. 534,309.

To all whom t may concern:

Be it known that we, Emana B. S'roite and STUART W. Pensons, each a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented new and Improved yllrunk Locks.j of which lthe following is a specification.

Our invention, while not limited in its nature of use, relates more particularly to the class of devices employed for locking the covers of trunks or similar receptacles to the bodies thereof, and an object of our invention, among others, is to provide a lock for such purposes that shall he extremely durable and particularly eflicient for theI 'purposes designed.

@ne form of device embodying our invention and in the construction and use of whichthe objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a face view of a trunk lock embodying our invention.

Figure 2 is a view in cross section through the same on a plane denoted by the dotted line 2-2 of Figure 1.

Figure 3 is a view in central lengthwise section through the same.

Figure `4 is a detail view in' lengthwise section through a fragment of the lock showing its manner of operation.

In the accompanying drawings the numeral 5 indicates a lock plate that is adapted to be secured to a trunk, usually the body thereof, or similar receptacle in any suitable manner, and 6 denotes a catch plate, also adapted to be secured to a trunk, usually the cover, or like receptacle. This catch plate has a rib 7 stamped up from the metal comprising the plate and extending substantially parallel with the border at a short distance therefrom, providing flanges through which screws, rivets or like fastenings may be extended. This rib is of considerable width and forms a recess 8 on `the face of the plate.` A catchA block 9 is secured to the catch plate within the recess 8 in any suitable manner, this block being of such size that its ends are spaced from the sides of the recess sufficiently to permit a link 10 to be received in such space, said block having a groove 11 in its upper edge to receive the link for the purpose of secur ing the edge of the trunk cover to the body.

n. sealing passage 12 is formed through the block, as particularly shown in Figure 8, to receive a sealing wire 18, that is eX- tended through saidpassage and around the link 10, the ends of such wire being secured as by a seal 14 in any well known manner common to structures of this class. A hasp receiving groove 15 is formed in that edge of the catch block opposite the'groove 11 for the purpose of receiving the edge of a hasp in a manner to be hereinafter described.

An important feature of this invention resides in the manner of securing the block 9 to resist sepa-ration of the edge of the trunk body and cover. This block may be secured against the surface of the catch plate by riveting, welding, or other fastening means, and a supporting lip 16 is formed at the edge of the recess 8, and as clearly shown in Figures 3 and 4 of the drawings. The block 9 rests with its lower edge squarely against this lip and thereby a particularly strong and effective means for resisting separation of the body and cover is provided.

A hasp receiving recess 17 is formed at the upper edge of the lock plate 5, extending to and opening out of the edge of said plate, as does also the recess- 8 in the catch plate. This recess 17 is formed as by stamping the metal to shape, and it is lo- `cated between the side parts of a bounding rib 18 extending around the plate substantially parallel with its edge, as does the rib 7 on the catch plate. A hole 19 is formed through the plate as by stamping, and a bor; 2O is secured to the back of the lock plate to close said hole 19 and form a Pocket for a lock case 21 secured in any suitable manner to a hasp 22. A flange 23 is formed at the edge of the hole 19, such flange providing a shoulder underneath which locking bolts 24 engage to retain the hasp in its locked position. The mechanism within the lock case may be of any desired coustruction.

A. hasp supporting block 25 is secured in the recess 17 against a hasp supporting lip 26, this support-ing lip being similar to the lip 16 en the catch plate hereinbetore described, and to support the block against a force tending to separate the cover from the body. Otherwise the block is secured to the lock plate in any desired manner.

Ears 2T are formed at the end ot a ange 28 extending along the edges ot the hasp 22, these ears being formed by increasing the width of the flange 28 at this point and by bending a fold 29 of the metal backwardly upon itself` to increase the thickness of such ear, and' as shown particularly in Figure 2 oli the drawings A pivot 30 extends through the block and through the ears 27 te piyotally attach the hasp to said block, and the link l0 is secured to the ears 27 at a point somewhat reinored trom the pivot 30, the link being formed 'from a rod of metal bent into rectangular shape and the tree bent ends ot such link being extended inwardly through the ears 27.

rlhe ends of the side parts et the hasp are rounded' to enga-ge within the rounded groove lo in the catch blofk 9, and these rounded ends are so formed with respect to the pivot that cover lifting cams 3l are provided, from which it will be seen, as illustrated in Figure that when the hasp is moved outwardly to disengage it from the lock plate these lifting cams acting within the groove 15 will cause the cover to be forced upwardly to ay slightextent. In structures of this class it frequently happens that the cover will stick, and often times considerable torce is required to disengage it from the body et the trunk. rl'he cam features just described provides means whereby the cover, under such circumstances, is, in a sense, automatically disengaged, as such disengagement follows the necessity of swinging the hasp outwardly to disengage it from the lock plate.

A sealing tongue 32, shown as broken away in l `igure 3 olf the drav-Jings, extends from a liange 33 on the lock case 2l, this tongue being bent around the lower edge of the flange 28 on the hasp and its tree end being extended outwardly between said flange and the end portion of the rib 18, as shown in Figure 3 of the drawings. A sealing wire 3e' may be extended through a. hole in the tongue 32 and through holes in op` posite sides et the rib 18, and a seal 35 may be secured to the wire in any manner common to devices of this class.
