BAG FASTENER.

`applicativa ined Amay 25,

Thisinvention relates to` devices for se- `curing `the frame sides of bags in juxtaposition and` has as one ofits objects to provide means forlatching the securingmeans `when in an adjustedjposition, the latching means beingA `resiliently held and actuated by a hand knob.

Afurther feature is in the provision of a fknob of artistic appearance rotatably mounted `onta stem hinged to one ofthe frame members totilt the stern vwhenreleasing a catch Ifixed on the mating frame member, in addition toitslatching "feature whichis acceui- `plished bypartialrotation of the knob.

These and other objects, which will become apparent fas the description progresses, are Vattained `by the novel construction `and combination of parts hereinafter de-` scribedand shown iin the annexed drawing forming part hereof, and in which Figure 1 isaperspective view of a conventional type of bag frame' showing anapplication of anembodiment `of the invention. i i

Figure 2 is an enlarged transverse sec tional view of the frames 'and vcatch elements thereon. V y

`li`igure 3 is a partial longitudinal sectional `view of the saine. f

Figure 4 `is a plan viewof the lframe and catch element thereon with the ornamental object removed.` lFigure is a perspective view oftheseveral elements in `detail "showing their rela tive position when assembled.

A common typeofvba g frame is illustrated in Figure l, the same consist'ingof two side elements 1() and r11 of :channel shaped cross section, pivoted together by rivets 12 at the ends of their angular projecting ends.

The rear side frame 11 has an elongated slot- 13 in the center of its outer edge through which freely passes a flattened loop 14 formed on the enlarged circular hollow base 15 of a post 16 held normally erect as later described, the post being cylindrical and terminating in a rectangular projecting lug 17 provided with a slot 18 in its extreme end.

It is to be noted that the loop 14 extends downwardly from the base at one side thereof, so that the axis of the base is centered substantially midway of the frames, and is held tightly by the flattened portion 19 of a torsion spring 20 passed through the 1927. Serial i No. 193,-965.

bight of the loop 14 and disposed in the in terior of the channel frame 11, the op- Aknob body 22having hollowbase 23, en-

circling the post base 15, and terminating in a fiat plate flange 24; having flattened sides `25, resting directly on the upper surfaces of the bag frames.

Rlgidly fixed on the mating side frame is a stud 26 .having `an angular inner, rear faceadapted to enga-goth@ edge of the flange i 2dandbase 15, causingthe post and lrnobfto y tilt `rearwardly until the stud has become fully entered within the chambered portion of the base, whereupon the torsion spring 2O operates to move the post and knob forward andretain the llug in the chamber, holding the frame sides tightly closed..

Also rigidly secured on the frame side 10, at uniform spaced distances from the stud 26,'are ya pair-of opposed upstanding keeper -plate elements 27, 4having longitudinally n curved `or bevelled upper faces, the space `between these elements `being receptive of the knob `base 23 while the ends of plate 24 may enter undercut recesses 28 in the adjatcent ends of the elements 27.

The enlarged'upperportion ofthe knob 22 is provided with a knurled band 29 to facilitate 'turning by Vthe lingers and contains an annular recess 30 having a iiooring level withithe `upper end of the main portion of `the post 16, as best seen in Figure 3.

A square block 31 having an opening 32 is iixed on the extending stein 17 of the post and impinging against one of the four flat sides of the block is the arm 33 of a spiral spring 34, the other end 35 of which is outturned and entered in a groove in the wall of the knob chamber 30, thus preventing the spring from rotating in the chamber except as the knob is turned.

Disposed over theblock 31 and spring `34 is a flat disc 36 having an opening 37 through which the end of the stem 17 passes, the stern beingupset thereover by spreading the notch 18 as at 38 in Figure 3.

The knob is completed by inserting an ornamental object, as the stone 39, within a counterbored space 40 above the chamber 30 and spinning the thin wall 41 of the knob, above the band 29, inwardly to permanently retain the stone in place.

In operation, when it is desired to latch the bag against intrusion, the knob is turned to position the ends of the plate flange 24 within the recesses 28, as shown in Figure 1, at which time the action ofthe spring 34 against the side of the block 31 retains the knob in adjustment and holds the vstud 26 within the chamber of' the post base Q3, preventing separation of the sides.

When it is required that the bag be opened,

'f the knob is turned through an angle of ninety degrees, the spring permitting the corner of the block to pass by exerting force on the knob, and the ends of the plate flange 24 become positioned transversely of' the frames to move upwardly between the ends ofi' the keeper plates 27 when the knob and post are pressed rearwardly, thus liberating the stud and permitting the bag to open, the knob being retained in releasing posi- `tion by the combined action of the spring and block until further rotated.

Although the foregoing is descriptive of the preferred embodiment of the invention, it will be apparent that minor changes may be made in its construction, without the exercise of invention. i

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

1. A bag fastener comprising the combination with a pair of hinged frames, of a tiltable post mounted on one ofsaid frames, a torsional spring in the frame to retain said post normally erect,` said post having a rhambered base,` a stud fixed in the other frame` said stud being engageable in the.

chamber of said post, a knob revolubly mounted on said post, keepers fixed on the stud carried frame, andmeans on said knob engageable by said keepers when in oneposition and tree therefrom, when the knob is in another position.

A bag fastener comprising the combina- 'tion with a pair of hinged frames, of ay post hinged on one of said frames, means to resiliently retain said post erect, a. stud fixed on the mating frame, means in said post to engage said stud, a` knob rotatable on said post, means on said post to resiliently retain said knob in an adjusted position, opposed keepers on the mating frame, and means on said knob to engage said keepers.

3. In a bag fastener having a pair of hinged frames, 'a post hinged on one of the frames, a `knob revolubly fixed on said post, ay torsion spring engaged with said post to retain it normally erect, a stud on the other frame adapted to engage said post, keepers on the last named frame, said keepers having undercut-recesses, and a plate fixed on said knob to become engaged or disengaged with respect to the recesses of said keepers.

4. In a bag fastener having a air of hinged frames, a tiltable post reslliently mounted on one of Asaid frames, said post having a chambered base, a stud on the other frame engageable-in the ehambered base, a pair of undercut keepers on the last named frame, a. knob completely enveloping said post, an elongated flange on the base of said knob, said fiange being engageable with said keepers, a. rectangular block fixed onthe end of said post, and a spring fixed in said knob to impinge on the edges of said block whereby the knob is resiliently retained in adjusted position.

5. In a bag fastener having a pair of hinged frames, a tiltable post resiliently mounted on one of said frames, a stud fixed on the mating frame to engage in the base of said post when upright, a pair of keepers adjacent said stud, a chambered knob completely enveloping said post, a fiange on said knob to engage said keepers, a block fixed on said post within the chamber of said knob, a spring fixed in the knob to imp'nge, the edges of said block, a disc on said `post to retain saidsbloek, spring and knob thereon, and means integral `with said post for securing said dise in operative position. This specification signed and witnessed this 12th day of May, 1927.
