SUITCASE LOCK Filed May 23, 1931 Patented Aug. 16, 1932 UNITED STATES PATENT; OFFIC ELMER B. STONE, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE AMERICAN HARD- WARE CORPORATION, NECTICUT OIE NEW BRITAIN, CONNECTICUT, A CORPORATION OF CON- SUITCASE LOCK Application, filed May 23, 1931. Serial No. 539,511.

My invention relates todevices for retaining covers of suit cases or other receptacles in closed positions and an object of my invention, among others, is to provide a device of this character that shall be simple in construction as well as simple'and efiective in operation, and one that shall present an extremely sightly appearance.

One form of a suit case lock embodying my invention and in" the construction and use of which the objects herein set out, as well as others, may be attained is illustrated 1n the accompanying drawing, in which- Figure 1 is a face view of a suit case lock and hasp embodying my invention.

Figure 2 is a edge'view of the same shown as applied to a suit case or similar receptacle. V p

Figure 3 is a view in lengthwise sectlon a through my improved lock and hasp.

Figure 4 is a similar view through the lock illustrating the manner of holding the catch in its retractedposition. V

Figure 5 is a rear face view of the lock and hasp.

' Figure 6 is a view similar to Figurefi but with the hasp. and back plate of the catch and the tumbler removed as denoted by the dotted line 66 of Figure 3.

Figure '7 is a view of a fragment of the lock plate looking from the rear.

Figure 8 is a front view illustrating a little diflerentarrangement. r h In the accompanying drawing the nu- .meral 8 illustrates a suit case and 9 the cover thereof which parts may be of any ordinaryand well-known construction. A

hasp plate 10 is secured to the cover in any suitable manner and a hasp 11 is pivotally attached to thehasp plate, said hasp having a spring 12 for forcing it to an open position. The hasp is preferably of box form,

that is, it is closed in on its front end and end is prod with areleasing lip 13 to be hereinafter referred to. A lock plate 14 is secured to the suit case 8 in any suitable manner, this plate having a bounding flange 15 enclosing a space back of the plate and between it and the suitcase.

'vided with flanges that rest against or in of the plate 14. A rib proximity to the face 17 is formed on the end of the catch to provide an operating thumb or finger piece.

Y A back plate 18 is secured to the catch 16, as by means of lugs 19 positioned. between clips 20 projecting from the back or bottom retaining plate 21 is secured to the catch 16 as by meansof holes that receive the clips 20 which are bent over to secure the parts in position, the retaining plate, when the parts are assembled, being located on the opposite side of the lock plate 14 from the back plate 18, the parts being secured in such manner as to afiord free sliding action of the catch and back including the retaining plates relatively to the lock plate 14. The retaining plate is located inythe space within the bounding flange on the lock plate hereinbefore referred to.

The retaining plate 21 has one edge 22 insertable between a catch holder 23 and the back of the lock plate 14 when the catch is in its closed position, the holder 23 being in the form of a spring secured to the back face of the lock plate and having a retaining lip 24 positioned to engage the edge of the retaining plate when the catch is in its releasing position thereby to retain the catch disengaged from the hasp. The releasing lip 13 on the hasp hereinbefore referred to is adapted to pass through an opening 25 in the lock plate and to engage the holder 23 to spring the latter backwardly to release the retaining lip 24 from the edge of the retaining plate 21, and when thus released, the

retaining plate is forced toward the hasp and and movement of said catch in the opposite direction is limited by engagement of the prongs or clips with the edge of the opening 28 in the lock plate.

thumb or finger upon therib 17 the nose 32 will be disengaged from the endof the hasp 11 and the spring 12 will immediately throw the hasp to its open position as shown in dotted lines in Figure 2.. When the hasp is thus moved back the holder 23 springs to a position infront of the retaining plate 21, thereby'holding the catch in its retracted position. WVhen the hasp 11 ispressed into its closed position, as shown in Figure 3, the lip 13 on thecatoh engages the holder 23 forcing bacl'rwardly and thereby releasing the retaining plate 21, which being secured to the back plate 18 and the latter being secured to the catch, the latter isforced to its holding position by means of the spring 26 which presses against the plate 18.

In order to lock the catch in its closed position I provide a bolt, 33 slidably mounted between. guides '34:. projecting from the ret'ainingplate 21, said bolt being located within the opening 28in the lock plateandbeing frictionally held by a: spring 35, a notch 36 in the bolt being engaged with one of the guides 34: and as shown in dotted lines in Figure 5 of the-drawing. An actuating notch 37in a side edge of the bolt isaclaptedtobe engaged by the bit of a key inserted. through a key hole 38 in the catch 16 whereby the bolt may be released from engagement with the guide 34 and moved backwardly. and disengaged from alocking prong39 extending Ifrom. the front edge of the opening, 28 in the lock plate 14. When the lock-ing bolt has its end located. opposite the end of said locking prong the catch. is locked against movement, and a key inserted in. the key hole 38 will .be required .to move the bolt to its unlocking position to permit movement of the catch, r

'In the structure shown in Figure 8 the plate 14, the hasp 11 and its supporting plate are substantially the same as hereinbefore described. with respect to the preceding .figures.the diiierence being that the sliding catch 16 is mounted. to slide vlengzgthwise of the plate 14. instead oficrosswise thereof and said. catch engages a side edge of the hasp 11 instead of the end thereot;

In accordance with the provisions of the patent. statutes I have described the principles of operation of my invention: together with the device which I nowconsider. to

will be noted that when represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative, and that the invention may be carried out by other means and applied to uses other than those above setout.
