OFFICE FASTENER WITH LOCKABLE CAMMING HASP Albert J. Komenak, Stamford, Conn., assignor to The Excelsior Hardware Company, Stamford, Conn, a corporation of Connecticut Application June 26, 1941, Serial No. 399,827

11 Claims. (01. 70-76) This invention relates to lockable hasp fasteners of the typ in which the loop forming end of a U-shaped hasp swings to and from a position extending around and hugging the casing of its lock mechanism.

is disclosed in my copending application, Serial No. 349,339, in relation to which the present improvements propose particularly to equip the 5 A lockable hasp fastener of this general nature looped nose of the hasp with a combined lockable 1c depth of the case of the lock mechanism at the 20 front of the mounting or escutcheon plate in order that all parts of the lock may operate exclusively at the front of said plate and at the same time necessitate no increase in all-over depth of a fastener where shallow proportions are highly desirable.

A further object is to embody-both the before mentioned locking means, and cam action or drawing-together means, in a single tongue of bent over formation which in the case of sheet 9 metal construction may originate from the material that is removed from the sheet between the spaced arms of the U-shaped hasp.

A further object is so to form such tongue and so to cooperatively relate it to the shape of the lock case that this tongue shall become quite inconspicuous or practically concealed when the hasp is closed.

A further object is to provide the before mentioned tongue with a. cam-like shape and dispo- 5 sition capabl of performing a camming action cooperatively with the lock case and preferably throughout as large an angle of swinging movement of the hasp as is possible.

A still further object is to render the lock bolt virtually tamper-proof when it projects from its case in looking position by shielding the bolt by means of the hasp and also by additional guard means flanking the extreme end of the bolt.

These and other Objects of the invention willc 'y appear from the following description of one mechanical form of the present improvements in which description reference is made to the accompanying drawing, wherein:

Referring to the drawing, the hinge abutment,

illustrated herein in the form of housing In, is provided with tongues (not shown) which penetrate its mounting plate [3 and are peened over against the back thereof to hold parts I!) and I3 together. By this means the hinge bar M of the loop-like hasp member 16 is pivotally anchored at'the front or rounded closed end I! of a bearing notch in the side walls of housing l0, being yieldingly pressed thereagainst bya leaf spring l9 which issecured by small rivets 2| to the mount ing plat I3. The latter is adapted, to be fastened, as by larger rivets 20, to the frontwall of a container lid l2 which may be hinged in usual manner (not herein shown) to a container body whose front wall is shown at H. Hinge bar I4 is provided with a flatted portion 24 separated from the arms l5 0f the hasp by rounded journal forming portions 25.

The flatted portion cooperates with spring H) to urge the hasp into either of its positions shown in Figs. 2 or 5, while the rounded portions afford a-- bearing fit for the hinge bar l4 within the rounded ends l'lofthe bearing notch. Mounting plate [3 is shaped to provide the usual dowel tongue 22 which projects downward beyond the housing Ill and beyond that edge of the container lid wall which abuts against the container body wall.

In that case lock bolt 31 may be shot out and retracted through a mere clearance affording slot or notch which could be provided in the bottom, and otherwise unbroken end wall of the lock case. .The provision of cutaway 36 affords a socket-like engagement of tongue 26 with lock case 32 which tends to hold the separable parts of the fastener more ruggedly in designed alignment under rough usage to which articles of baggage and the like are commonly subjected.

Departure in details from the exact constructions and relationships of parts herein disclosed may be resorted to within the scope of the present invention and the appended claims are intended to refer to and cover all substitutes and equivalents for constructions and relationships of such parts as would be suggested hereby and fairly come within the terms of the claims.
