:BAG LOCK.

Application led March 24, 1925. Serial No. 17,878. i i

This invention relates, generally, to locks; and, the present invention has reference, more particularly, to improvements in bag-V locks employedv with the usual complemental frame-members or sections of a bag frame, with a view of providing, primarily, a lock-construction the mechanism of which is to be operated byV akey, but in which the push-member of the lock is provided with means which permits of the mechanism to be operated only by a certain key.

In other words, while the construction and the arrangement of the parts of the mechanism of the lock is the same in all locks, the means within the pushunember which permits the turning of the key, varies with the several locks, so that different keys are necessary with different locks.

This invention, therefore, has for its principal object to provide the push-members of the usual bag-locks, with simply constructed means within the push-member of the lock, which will allow of a cert-ain key turning within said member, but will remain inoperative when another key is inserted.

Another' object of the present invention is to provide with the casing of a bag-lock, and its mechanism therein, a push-member made of castor similar metal, instead of being formed in sheet-metal, as heretofore, Vso as tok produce a push-member of greater strength, and one `in which there are no rough Vor sharp edges due to the imperfect structure of the member, as is so often the case, where the push-member is madefrom sheet-metal. v v Y l Other objects of the present invention not 'at this time more particularly enumerated will be clearly understood from the following detailed description of the said invention. Y

With the various objects in view, the present invention, consists in the novel bag-lock hereinafter set forth; and, the said invention consists, furthermore, inV the novel ar` rangements and combinations of the various devices and parts, as well as in the details Y of the construction of the said parts, all of which will be more fully described in the following specification, and then finally embodied in the clauses of the claims, which are appended to and which form an essentialf part ofthe said specification.

the drawings.

The invention is illustrated in the accompanying drawings, in which i Figure l is a view of a fragmentary portion of a bag-frame section, looking toward the interior of said section, andshowing in elevation, in connectionvwith said frame-section, a bag-lock madeaccording to and embodying the principles of the present inventlon.

Figure 2 is a longitudinal vertical sectional representation of said `bag-frame section and an elevation of the lock attached thereto, looking at the lock from the opposite sideof that shown in said Figure l; Figure 3 is a longitudinal vertical sect-ion of the lock, shown detachedv from the framesection; and Figure 4 is a horizontal section, taken on line 4 4 in said Figure 3, looking in thedirection of thearrow m. 4

Figures 5, 6 and 7 are perspective views of threepush-members to be used with the lockmechanism, shown provided Vwith variously located key-stops, and the correspond ing and variously notched keys adapted to be used with the said push-members.

F ig-ure 8 is an end view of one of said push-members; Figure 9 isA a longitudinal vertical section ofthe same, said section being taken on line 2)-9 in said Figure 8; and FigureylO is il. perspective view of the key-receiving barrel used with the pushmember. i t

Similar characters of reference are employed in all of the said above described views, to indicate corresponding parts.

Referring now to the said drawings, theV reference-character l indicates a 'portion of any usual bagframey section to whichv the lock is attached in a manner, substantially as indicated in Figures l and 2 of thedrawings. 1

The lock comprises any yusual casing, the

one here shown consisting of the longitudinally extending side-face 2, the base 3, and the end-members 4, thus providing a casing which is open at one side, but which open side is placed aga-inst the vertical flange.

member 5 of the frame-section l, as will be evident from an inspection of'Figure` l of vided, iszformed in its side-face 2 with suitably ldisposed hasp-lug `receiving openings This lock-casing, thus vpro- Y 6, and connected with and extending inan which is selig-evident.

upward direction from each end-member l is a fastening ear or lug 7. These ears or lugs 7 are inserted through correspondingly located slits or openings 9 or' a top-plate 8, said plate being formed along one or' its longitudinally extending marginal edges with the usual right-angled flange 10, and connected with and extending from the ends or' said top-plate are suitably 'ornied fastening ears or lugs 11 which are inserted in and passed through the usual slits or openings in the traine-section 1, and are then passed through correspondingly located slits or openings 13, indicated in dotted outline in a )late 12 of `Vthe usual casinO 1d located upon the upper and outer tace oi' the frame-section l, as indicated in Figure 2 of the drawings.

Vithin the said lock-casing is the usual key-operated locking-mechanism comprising the sliding bolt or latch-plate 15, and the push-lug-operated bridge-member 16 which is provided with upwardly extending lugs 17 adapted to be brought into retaining engageinent with the usual hasp-lugs 18, as indicated in said Figure 2, when said lugs 18 enter the openings 6. 'lh-e said bridge-meinber 16 is mounted upon the posts 19, secured at their lower ends to a plate 2O and to the said base-plate 3 oli' the lock-casing substantially as shown in Figure 3 of the drawings. Encircling said posts 19, between said bridge-member 16 and the said plate 2O are coiled springs 21, the purpose of In connection with said bridge-member is the push-member of the bag-lock, the said push-member being depressible when the bolt or latch-plate 15 is in the vposition indicated in Figure 3 of thedrawings, :tor the withdrawal of the lugs 17 from their holding engagement with the hasp-lugs 18, as will be evident.

The above-mentioned push-member consists, essentially, cfa main cast-metal bodymember 22, preferably ot rectangular configuration, as indicated in the several figures of the drawings, `the said body-member at its lower part being provided with an oit-set portion 23, usually formed with a cut-out portion or-recess, as 24. Extending frein said oit-setportion 23 are posts'25pthe endportions 2G of which are fitted into suitable perforations 27 in the bridge-member 16, and are riveted over or upset against the 'lower face of the bridge-member for positively securing the push-member upon said bridge-member. The said body-member 22 is also forined with a cent-ralrand vertically disposed central bore, as 28, the upper open portion of which is marginally bounded by an annular rib 29, la portion of which is cut laway or slotted, as at 30. Also suitably maintained in position upon the bridgemember 16,by means Aoi? an extension 32, rotatably disposed in an opening l33 in the bridge-member, is a key-receiving barrel 31. This barrel, as will be seen roin Figure 10 or' the drawings, is inade with an 4annular rib 311, an enlargement 35, and with an annular oft-set- 36, all arranged so as to perinitof a rotatable arrangement and .the operative retention of the key-barrel within bz'irrel-receiving bore ol" the push-member, as will be evident from an inspection of Figure 3 ot' the drawings.

The said vkey-'barrel is `furthermore longitudinally slotted, as at 37, the slot passing through the body ot said barrel, andfalso throughfthe parts 36, 35, 3% and 32 of the saine, as indicated in said Figure 10. Inserted and secured in a hole 33, extending laterally through one side oi? the body-ineinber 22 of the push-member is a controlling ineans, in the torni of stop-pin V39,the inner end-portion of which extends into and terininates in the annular space a0 i'ornicd by the wall oil the bore 28 and the respective surface-portions of the parts 31, 34C and 35 of the key-barrel, substantially as shown in said Figure 3 of the drawings.

The key used with the said key-barrel is indicated by the reference-character and is oi' the flat style to permit ot' its insertion in the slot- 37, and the parts of the key tor actuating the lock-mechanism are of lthe usual shapes. in order, however, to enable the key to be used with the push-member shown in Figures 3 and 5 of the drawings, the key i1 is provided in its edge a2 with a cut-away or recessed portion 43', corresponding to the location orI the stop-pin 39l so as to permit the turning ot the key past the :inner lend-portion oil' the stop-pin terminating and located in the space 40, duringthe lock-V ing and unlocking` operations of the key, as will be fully understood from an inspection of said Figures 3 and 5.

.Referring now to Figures 6 and 'Tof the drawings, it will be seen, Athat the stop-pins 39 inay'be rvariously locatedin the body ot the push-member, and that different keys, as la and 45,supplied with correspondingly located recess i6 and 17, niay be provided, so that the key al, can only be used with'the push-member,shown in Figure 5, the key 44 only with the push-member shown in Figure G, andthe key e5 only with the pushinernber shown in Figure Of course, it will be` understood, that other combinations of the pins 39 and .the recessed portions of the keys niay be made, and that it desired, the push-members may be provided witha plurality: ofpins 39, the keys being provided with a .corresponding nuinbeiof such variously located recesses in the edgesy of the respective keys.

As has been previously stated the kpushnieinber is inade from cast-metal, or a solid block of metal, with Vthe bore thereofbeing produced by drilling,inay.be,used, the pur- :mam

pose being to do away with the usual form of hollow sheet-metal push-member which is objectionable in that it lacks strength, is unfinished in appearance, and is often left` with objectionable sha-rp marginal edges, which with const-ant use open up, and thereby leave unsightly seams.

Of course, I am aware, that other changes may be ,made in the general arrangements and combinations of the various devices and parts, as well as in the details of the construction of the said parts, without departing from the scope of the present invention as set 'forth in the foregoing specification, and as defined in the clauses of the claim which are appended thereto. Hence, I do not limit my present invention to the exact arrangements and combinations of the various devices and parts as described in the said specilication, nor do I confine myself to the` eX- act details oi the construction of the said parts, as illustrated in the accompanying drawings.

I claim l. A bag-lock comprising a casing, a depressible hasp-engaging means within said casing, an upwardly and exteriorly projecting push-member secured to said hasp-engaging means, leyactuated means movable to obstruct or release said hasp-engaging means for operation, said push-member having a. vertical bore, a. key-receiving barrel rotatable in said bore having a longitudinal key-slot open along one side thereof, said barrel having at its lower extremity a reduced axial extension journaled in said haspengaging means, said barrel having intel1` mediate its ends a reduced portion providing an annular space between the same and the Walls of said bore and a stoppin iixed in said puslrmember togproject into said annular space in predetermined position `to match with a selectively located clearance notch of a proper key inserted in said barrel.

2. A bag-lock comprising a casing adapted to be attached to a bag-frame, a lock-mechanism Within said casing, a spring-supported hasp-engaging bridge-member cooperating with said lock-mechanism, a push-member 'for actuating said bridge-member, said pushmember having an axial cylindrical bore, a key-receiving barrel rotatable in said bore and provided with a longitudinal open l{ey slot, said barrel having a portion at its lower end journaled in said bridge-member, means at the upper end of said push-member to re tain said barrel against longitudinal displacement from said bore, said barrel having a reduced portion providing an annular space between the same and the walls of said bore, and a stop-,pin lixed in said push-member to project into said annular space in predetermined position to match a. selectively located clearance notch of a proper key inserted in said barrel.

In testimony, that I claim the invention set forth above I have hereunto set my hand this 18th day of March, 1925.
