UNITED STATES hat WILLIAM C. HIERING, OF NEWARK, NEW JERSEY, ASSIGNR Tt) l'. Il. NEWARK, NEW JERSEY, A. CORPORATIN OF Dlilntiwllalt BAG LOCK.

Application led December This invention relates to fastening devices, more particularly as applied to bags, using the term generically, to hold two adjacent parts lirmly together along their' meeting edges.

One of the objects of the invention is to provide a hasp, hingedly engaged on one of the members of the article to be secured, and carrying a spring actuated detent engageable 'with a lreeper lined on the mating member of the article.

A further feature is in the provision of means by Which the detent may be normally retracted and other7 lrey actuated means, co operative therewith, to prevent retraction of the detent by the lirst named means, but which permits of engagement irrespective of the key actuated means.

Another aim is to produce means Whereby the hasp is normally raised out of engagement with the keeper.

It is a further purpose to provide a device composed of few and simple parts, capable of economic production, readily assembled to produce a neat and attractive fastener susceptible of wide general application.

These and other important aims, objects and purposes are accomplished by the novel construction, combination and arrangement of parts hereinafter' described and shown in the accompanying drawing, constituting an essential portion of this disclosure, and in whichzm Figure 1 is a front elevational view of an embodiment of the invention, illustrating its application.

Figure 2 is a side view of the same, shown in a closed position.

Figure 3 is a similar view but showing the hasp as raised and released. from the detent.

Figure 4l is a longitudinal sectional vien taken on line fle-t of Fig. l and drawn to an enlarged scale.

Figure 5 is an enlarged plan view of the lock casing and mechanism therein, looking from the under side thereof, the parts being in an unlocked position.

Figure 6 is a similar-view of the same, as the parts appear in a locked position.

Figure 7 is a bottom plan view of the hinge, carrying member and hasp raising spring.

Referring in greater detail to the drawing, the numeral l0 designates one of the inem-- bers of the bag or other article and lll the mating member of the saine. Elu

The permanent, hinge ca V of the loch consif e to produce a hollenT casi above the surface of the li reason of its cnclosimr rml project prongs lil, aoapted to pass the Wall l() and al o a thin il forcing plate l5, if the n yielding yiiliablc nature, the E ii'imwi bent tightly thereover to afford a secure strip..

The shape of the casino' may be 'vari will and the manner o: securii Wall l0 is one of choiceJ not exactly as shown.

'lhe front por parallel and adjacent the edge or the is sheai'ed at the einls and ciu l to i elongated central hinggge elem tially at its lovver si e to udn 17 of a flat spring, the main p( which is disposed AVwithin the oasiu held firmly against the inner surface top HYall by prongs lll sliearod from the if Wall, in a manner lilre the e shag, A l

bent to impinge en the of the spring, as u i lli il; and

A liasp il() is forii'ied of sheet metal with down turned edges 2li, s iimilar to the editeL` of the hinge casing and of the salue lu g these edges reenforcingI the hasp and impro i ing its appearance.

The main portion of the hiusp is of uni-- form Width, blending into a Wider base por-- t-ion, sheared at the niiddle and cil each side to present tiro hiwi el i conforming with the clcmen thereto by a hinge pin Elli iu. th i ner, and it is to be noted that the fr' "'i i 17 is arranged to operativey ci tral portion of the hasp, in fro. i of the hinge, acting to press the liasp out Ward or away frein the bag material ll, over Which it extends.

The forward, free, end of the liasp il@ contains a circular opening 24, the surrounding metal being drawn upward to form a short cone or cylinder 25, cut out on the side adjacent the hinge, as at 26, for a purpose which will presently appear.

Enterable into the cone 25 is the rounded circular head 27 of a keeper stud, the reduced stem'28 of which extends from a disc 29, loosely fitting the opening 24 and formed on a plate 30 held to the bag member 11 by prongs 31 passing therethrough and clinched over a thin reenforeing plate 32 on the under side of the material.

The lock mechanism is contained in an oblong rectangular casing 33 of lesser width than the lever 20 and secured centrally on its free end by prongs 34, extending from the side Walls 35 of the casing, which join the .front and rear end walls 36 and 37 respectively, to ,constitute a complete closure except for a key hole 38 in its cover portion.

Slidaloly mounted in the lock casing 33, against the inner surface of its cover, and filling the space between its side walls 35, is a push piece 39 having a narrowed frontend 40`extending through an opening in the front wall 36, this projection being smoothly finished to be operated by the fingers in releasing the catch, as will be seen.

The projection 4() has at its sides square shoulders 41 that limit the outward movement, of the push piece 39, which contains a central elongated opening 42 into which the tube25 enters and also the head 27 of the detent.

A recess 43 in the inner portion of the push piece separates the same into two forks 44, 45, both forks being reduced at their left hand side edges to provide extensions 46, 47.

Disposed on the push piece are the downwardly flanged edges 48 of a flat bolt 49 having forwardly extending arms 50, spaced substantially in accordance with the width of the opening 42, and into this space extends a central forwardly projecting lug 51, concavely curved at the front edge and rounded on its upper corner to make contact with the detent head 27, below which it engages, when passed through the opening 26 in the tube 25.

A pad 52 is bent at a right angle from the i rear edge, at the center of the bolt 49, to

contact with the casing cover 33, being movable in the recess 43 of the push piece 39, and extending rearwardly from the Vpad is a lug 53, adapted to retain the notched end 54 of abent Hat spring 55 in operative position on the pad. f

rl`he opposite end of the semi-elliptical spring 55 bears againstI the inner surface of a channel shaped controller 56, movable transversely in the rear portion of the casing, against'the wall 37 and is provided with two indentations 57, 58, either of which is engageable with a protuberance 59 on the inner surface of the wall to hold the coutroller in either of its adjusted positions as moved by a key GO inserted through the key hole 3S.

The lower wall of the controller 5G is shaped to present two forwardly extending stops 61, 62, relatively wide and narrow, and so arranged that when the controller is moved to one side of the casing as to permit the push piece 39 to be pressed inwardly, as shown in Fig. 5, but when at the opposite side of the casing the fork projections 4G, 47 make contact with the stops (l2, (il preventing retraction of the push piece 39 but permitting the bolt 49 to move inward ly against the gr :'-ure of the spring 55.

The upper wall of the controller 5G presents simiiar but longer forwardly extending arms 63, G4 having between them a space through which the ward of the key G() may extend when entered, the ward being contactable with either arm of the controller by which it is moved by turning the key thereby iermitting the push piece to he pressed in or held positively extended as in Fig. 6.

It is to be noted that the bolt 49 is at all times free to recede, as by making forcible contact with the detent head in closing the hasp irrespective of the position of the controller, or by pressing the push piece 39 into the lock when the controller is in position toV allow this to be donc, as in Fig. 6.

Thus itis possible, by proper use of the key to prevent entrance to the bag at will or to release it for actuation by the push piece, in which case the hasp is instantly raised by the spring 18 and retained until the hasp is pressed down and catch element 51 reengages with the detent.

From the foregoing it will be seen that a simple device for this purpose has been disclosedin the preferred form of its embodiment, but it is not desired to restrict the details to the exact construction shown, it being obvious that changes, not involving the exercise of invention, may be made without conflicting with the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
