FASTENING DEVICE.

Application filed May 28,

To all whom it may concern:

Be it known that I, JAooB F. LANGENAU, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Fastening Devices, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present improvements, relating, as indicated, to fastening devices, have more particular regard to looks or hasps of the sort used on trunks, suit cases and the like, characterized by having a hasp in the form of a link that is carried by a pivotal member so as to engage with a hook-like member or projection when in looking position. The

object of the present invention is to provide supplemental means for securing such pivotal member in place when the hasp is in such locking position, the means ordinarily provided for this purpose consisting of a pin or stud member which more or less tightly fits into an aperture in the base plate to which said member is attached.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and the following description illustrating but several of the various mechanical forms in which the principle of the invention may be embodied.

In said annexed drawing Fig. 1.is a front elevation or plan view of a fastening device embodying one form of my prevent improvements, said device heing shown in its closed or looking position;

Fig. 2 is a side elevation of said device with parts shown in section as indicated by the line 22, Fig. 1; and Fig. 3 is a view similar to Fig. 1, but showing the pivotal hasp-carrying member removed so as to disclose more clearly the supplemental locking device.

Referring to the constructional form of the invention illustrated in Figs. 1, 2 and 3,

the familiar parts of the fastening device comprise two base plate 1 and 2, which are respectively designed to be secured in abutting relation to the main body and the cover or lid of the trunk, suit case or other similar article. R-igidly attached to said plate 1 1920. Serial NO. 384,809.

is a hoolslike projection 8, the undercut face of which extends in a direction away from the edge of the plate lying in abutting relation to plate 2. Rigidly attached to the latter is a projection 4;, preferably in the ber 6 is swung outwardly, to engage beneath the hook-like projection 3 on plate 1, and when said member 6 is thereupon pressed backwardly against the plate 2, the two plates, with the parts of the trunk or equivalent article, will be forcibly drawn together.

As shown, the pivotal axis 5 of the memher 6 should lie without the plane of the link in the locking position of the parts just described so as to minimize the tendency for the member 6 to swing outwardly to releasing position; however, I have found it desirable to add a supplemental locking device in order to insure against any but purposeful opening of the lock. With this in view the upper end 8 of the member 6, which is curved to present a convenient finger piece for operation of the look, as

shown in Figs. 1, 2 and 3, is formed with an aperture 9 adapted to fit over a V- shaped stud 10 that projects outwardly from the face of the plate 2, or rather from a supplemental plate 11 secured there to. Slidably secured in place by means of such supplemental plate 11 is a reciprocable member 12 carrying an undercut stud 13 that projects through an aperture 14 in said plate 11 laterally adjacent to said stud 10. A spring 15 is disposed behind the slidable member 12 so as to press the latter outwardly, and thus force the stud 13 into locking engagement with the aperture 9 in the handle-extension 8, as shown in Figs. 1 and 2. The outer face of the stud 13 is beveled to conform with that of the stud 10, so that said handle-extension maybe forced down over said stud 13 without manipulating the slide 12; however, the outer end 16 of the latter is upturned for convenience in pressing the slide back when it is desired to release said extension from said stud 13.

The foregoing supplemental locking device, it will accordingly be seen, affords simple and yet effective means for p0sitively retaining the member 6 With the hasp 7 in locking position. There is of course no particular strain placed upon the stud 13, so that the parts of such supplemental locking device may be made of relatively light construction, and yet prove sufliciently substantial for the purpose in hand.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any or the following claims or the equivalent of such stated means be employed.

1 therefore particularly point out and distinctly claim as my invention 1. In a fastening device of the character described, the combination with two plates designed to be secured in abutting relation on the parts to be fastened together, a hooklike projection rigidly mounted on one of said plates, a member pivotally attached to the other plate, and a link carried by said member and adapted to engage said pr0jection to lock said plates together, said memher being formed with an aperture adjacent its free end; of a guide stud fixed on the corresponding plate adapted to be received in the aperture in said member; and a slide carried by said plate and provided with an undercut stud lying alongside such firstmentloned stud and adapted in one position of said slide to inter-lock with said aperture.

2. In a fastening device of the character its free end; of a guide stud fixed on the COI responding plate adapted to be received in the aperture in said member; a slide carried by said plate and provided with an undercut stud lying alongside such first-mentioned stud and adapted in one position of said slide to interlock with said aperture; and a spring normally holding said slide with said last-mentioned stud in such locking position, said slide being formed with a linger piece for operating the same against said spring.

Signed by me, this 26th day 01 May, 1920.

JACOB F. LANGENAU.
