:BAG EAsrENER.

Application med-December 3,1920. YSerial'No. 427,945.

To all whom' t 'may concern i Be it known that I, FRANZ A. FULLER, a citizen of the United States, residing in Newark, in *thel county of Essex andV State l`of New Jersey, have invented vcertain new and useful Improvements in Bag Fasteners, 'of which the followingis a specification.

This invention has as` its main object to provide abag fastener whereby thev two metal side frames of the bag may be either4H temporarily 'securedin engagement' by'spring actuated bolt devices readily lrelea'sed by hand, orl positively locked in such manner 'as to'require4 a key inorder to separate the same in obtaining ,accessto the bag.

Afurther object is toprovide av neat and attractive ty e of bag fastener comprised of'fewand simple parts, cheaply constructed' and readily applied.

These and other analogous objects are vattained by the novel co'nstructiomcombination and arrangements of kparts herein. yafter described and shown in the accompanying drawings forming a material part` of' this disclosure, and in which 1'- 'Figiire l 1s a fragmentary vside elevational view of a conventional type of bag showing a fastener made inl accordance` wth the invention in operative position.

Figure' 2 is an enlarged longitudinal sectional view of the fastener, showing in lease the frame sides. s

A capj'pieceBO:alsohollow and smaller in n' length and width is slidably mounted on the casing, this cap having a transversely curvedtopfeXcept-'at its raised flat. centerv y31 which has an expanded central socket 32;

,Soldered or otherwise vsecured `within the plate 2O conveying lineal motion tothe saine and "fat ythe same timeslidably securing the lcap'andpla'te Btothe casing. g

i lThe plate .35 isfor'medwit-hraised angl-1'; i

larly lturned edgesj36" and .36` serving as tain than in a' lacked-position..

Formed. inthe plate 35 are two raised elei mentsl 8y adapted yLto reduce `thearea in '.fri'cn tional` contact',with the plate 20 and 'midr` yway `in itslength, to one side-jef the center vis' a single raised stop 39 yadapted to make contact/'with' thel ends of the openings 27 ico A post or stud 40 extends slightly above the cap element 3l, through which, together with the reenforcement 34, it passes.

The upper end of the post contains an aXial bore 4l and a cross slot 42, the former being receptive of the point 43 of the key 45, the broadened portion 44 of which engages the slot 41 while the nibs 46 prevent the key from entering an undesirable depth.

At the inner end of the post is a flange 48, between which and the `plate 34 is a 'compression spring 49 encircling the post,

Y' tending` to press the flange 4S towards the plate 20;

Formed on the outer surface of the flange is afrectangular lug 50 having .straight yparallel sides extending from the center to the@ periphery of the flange in alignment with the slot 41.

.Extending from the lug axially of the post, is a pivot 51, the same passing through a guide opening appropriately formed in theplate 35. f

' Another compression spring 52 is disposed within the cap, extending from one end to the prong 26 byy which it is maintained in operative position, this spring acting to press the cap into engagement with the stop 39 `causing the cap and, casing to normally register but-permitting the cap to be moved at such times as the lug 50 is turned into the position shown in Figure 2.

`Then-it is desired to lock the` bag, the

' key is inserted and the post rotated, bringing the lug into the position shown in Figure 3, this turning of the post causing the lug 50 to rise-as it passes over the top of the stop 39, against the spring 49, the opening 27 tpermitting the lug to be turned forward or back through 180-degrees only.

' Obviously when the parts are in the posii tion shown inFigure 3, that is the outer end carried by it cannot be moved lengthwise of they lug being inv-contact with the straight wall of theopening 27, at its left hand end as illustrated, the cap and parts of the easing into the positionshown by the broken lines in Figure 2 and the bag is effectively locked'against intrusion.

lt will be equally apparent that when the position of the lugy is reversed the parts can be moved against the force of the spring 52,

permitting the catches 17 to be withdrawn from engagement iwith `the sliding bolt eleonly', and notlas restrictive'or.limitative ofy the -invention, 'of which .obviously an embodimentmay be1 constructed including many minor modifications without departing from the general scope herein indicated and denoted in the appended claims.

Having thus described my invention, what l desire to secure by Letters Patent is l. A bag frame fastener comprising an elongated casing provided with an internal cam in the top wall thereof fiXed to one of the frames, a bolt element slidable therein, means in said casing for normally projecting the bolt in one direction, a catch carried by the other of said frames, said catch being engageable with said bolt, and key operated means engageable with said internal cam in said casing adapted to confine said bolt, 80

when in one position and to release the bolt when in another position.

2. A bag frame fastener comprising a fixed elongated casing, a hollow element slidably mounted thereon, a catch enterable 85 -into said casing, means on said slidable element engageable with said catch, means in said slidable element normally causing its engagement with said catch, an internal cam in the top wall of said casing, a key operated post journalled in said slidable element, an offset lug on said post operable in said cam and means for resilientlymaintaining said post in either of two adjusted positions, said lug when in one position preventing the movement of said slidableelement and permitting it to release said catch when in another position.

3. The combination in a bag fastener4 comprised of engaging elements fixed respecktively on the frames of a bag, oneof said elements carrying a longitudinal slide having means for engaging the other element, of a post rotatably mounted in the sliding member, said post having an opening receptive of a key whereby it may be rotated, a plate slidable in the element carrying the slide, said plate being moved thereby, an internal `cam in said element above said plate, an offset lug on said post operable in said cam, saidr cam limiting the movement of said lug, a stop on said plate engageable by said lug over which the lug rides when rotated, means for pressing said post towards said plate and means carried by said plate engageable with the other of saidfiXed elements.

4. ln a bag frame fastener, the combination with a casing provided with. an internal cam in the top wall thereof fixed on one frame, a slide onsaid casing and a catch carried by the other fra-me, of a plate in said casing slidably secured to said slide and having means for engaging said catch, a spring in said slide operating to retract it when extended, a key operated post rotatable in said slide and plate, a fiange on said post, a compression spring encircling said post for maintaining it in operative position, a lug on said post extending from the i90 vcenter to its edge,saidlug being operable This specification' signedanl Witnesecl in an opening in said Casing having an in- .this 29th day .of- November, 1920. ternal earn profile and a stop. formed with saidl plate adapted to retain said lug in n 5 either of two adjusted. positions, said stop Witnesses: p' l Y v lbeing movablel longitudinally inthe -men- `OSCAR A, RUNDZIEHER,
