Application led November 21, 1914..v Serial'No. 873,258.

To all wtom t may Concern:

e it known that I, FRANZ A. FULLER, a citizen of. the: United States, residing at Newark, in thecounty of Essex and Stateof' ew Jersey, have invented certainnew and usefulv Improvements in which thev following-isa specification', refeikA encebeing had therein to thek accompanyingdrawings, which form a part thereof.

My invention relates to bag fasteners and more particularly to a type thereof applicable to` bag frames having pivotally` con'- nected frame members and'embodying therein a lift latch adapted to lock said frame members when closed.

In bag frames of the character above referred to, two hinged framemembersformed of'channeled metal stock are used, and the bag body is secured. to the frame by having the edges thereofinserted in the chan-l nel of said members. These edges maybe held in the frame members in any desired manner or by any desired or Well known means.

The channel of the frame members being ordinarily narrow and relatively deep, great diiiiculty has been heretofore encountered in mounting the lift latch and its controlling spring in relation to the frame member carrying the same. Furthermore, the ordinary construction of this lift latch mechanism has been such as to interfere withthe conllection of the bag body to the frame meniers.

A bag fastener made in accordance with my invention is so constructed that its attachment to the frame members may be accomplished without obstructing the channel in either of the body members. By thus keeping these channels free of obstruction, the frame members may be more readily covered, and a proper, substantially uniform clearance for the insertion of the edges of the bag body at all points of the frame members, is secured.

The controlling spring for the lift latch member is located eXteriorly of the frame member, being situated within and concealed by, a box-like support mounted upon the frame member; and structed that the assembling of the support in relation to the frame member will the requisite tension in the spring. This. spring when in tension will be subjected to a torsional stress having a normal tendency Bag-Fasteners; of?

said spring is so con-` develop l from`4 theother members, having the sameA operative tendency, while permitting that slrghtside sway of the lugjupon said lift memberor knob' incidental to theactnation.

thereof;

The construction of the bag fastener is such as to permit the convenient assembling of the various parts a minimum of operations, nism maybel assembled in manner to preserve the artistic lines` of the frame. Y

The invention consists primarily in a bag fastener embodyingtherein a frame consist.` ing of hinged frame members, a boxe-like support having anv openingin the top lherev of, a lift member or knob provided.

andi this mechaof which is projected downwardly and across said support whereby itis adapted, when the support is mounted upon said frame member, to'engage the top of said. frame member ber; and in such other novel features of construction and combination of parts as are hereinafter set forth and described and more particularly pointed out in the appended.

Referring' to the drawings:

Fig. 6 is a detailed view of a similar boX- like member carrying the nose or catch.

Like letters refer to like parts throughoutthe several views.

In the embodimentof my invention shown ring box-like entering theremtor, with the fran le inV with a project through .said oj'ieningclaimV hereto CIK in the drawings, the frame members are shown at a--Z the main body of said members being provided with hinge members a a?,- b b2 respectively. Said hinge members are pivotally connected at c--0. In the form of the invention shown the :trame members a-b are composed of channeled metal stock. The faces of said members presented toward each other when the bag is closed are substantially parallel so that these members may be brought close together. ings, the members a-ZJ are shown as being substantially rectangular in cross-section, thus presenting a flat top. The bag fastener shown in the drawings is especially adapted for frame members of this coniiguration, although as it Ywill hereinafter appear, the coniguration of the frames is immaterial so long as a suitable bearing surface is afforded adjacent the lift member or knob for the purpose of engaging and tensioning the spring.

In conjunction with the frame member a, I provide a box-like support CZ having a substantially flat top, and pendant sides @ZL-Z2 adapted to have a sliding fit over the said frame member. The top of said support is provided with lugs e adapted to pass through openings in the frame member a and be upset within said frame. The sides d Z2 are provided respectively with lugs f-f adapted to foldV over and be clenched upon the lower edges ot' the said frame member. The top'of the support Z is pierced at g to provide an opening through which the lug of the lift member or knob is adapted to pass so as to be presented within said support. The opposite ends of the top of the support (Z are drawn downwardly slightly to act as stops for the purpose of providing clearance between the top of said support and the top of the frame member a for the free movement of the lug of the lift member or knob.

The lift member or knob Zz, is of the usual construction and is provided with the usual pendant rim 7b adapted t0 cooperate with a nose or catch upon the other frame inember b. Pendant from the member or knob l1, is a lug 'i adapted to have operatively connected therewith the controlling spring for said member or knob. This lug ordinarily is provided with a spring socket Vextending longitudinally therethrough which socket is angular so as to afford a proper seat for an angular portion of a spring.

Carried within, and concealed by, the support (Z is the liftmember or knob controlling spring consisting of a looped spring one arm y' or' which is angularly formed, as at j', to have a sliding fit with the socket in the lug c', and the other arm Zt' of which extends parallel therewith and has its end 7c" Vturned at an angle thereto so as to be projected downwardly and inwardly of said support to a In the draw-V various lugs point below the lug i. The end Ze projects beyond the end y" so that when said spring is assembled in relation to the lift member or knob, it will be at one side of the lug z'. The length ot' the turned end 7c is preterably such as not to exceed the width of the top of the support (Z.

I provide the frame member b with a similarly constructed, box-like member Z having riveted thereto a nose or catch member m and provided with a loop fn, Vcarrying pull o. The support Z is attached to the frame member b by means of lugs in the same manner as the-support eZ. Y

l/Vhen the lift member or knob h has been assembled in the boX-like support Z by the insertion of the lug /Z thereof through'the opening in the said support, the angular end y" of the spring j-cis slipped Vinto the socket in said lug; thus bringing the turned end 7c beyond said lug so positioning it that it is presented downwardly and inwardly of the said support. The sides 6Z-(Z2 of the support are then slipped over the frame anY and the lugs e inserted through the openings in the top of the trame a. As the support Z is forced to place, the spring end Za engages the top of the frame. The subsequent movement of the support imparts such movement to said end 7c as to upon the entire arm 7c with a resultant torsional and direct stress upon the arm j.;

These stresses will have the effect or' normally holding the member or knob 7L downwardly.

By arms, to be operatively connected with the litt latch lug vl and the end of the other arm being turned at an angle so as Vtoengagea suitable bearing surface on the topY of the :trame member, the mounting ofthe support for the lift knob upon the Jframe member will impart a rotative movement to the spring arm having its end so turned with a using a looped spring having parallel resultant slight torsional Vand direct tension of the other arm. Y

When it is desired to release the latch,

Vthe i develop torsional stressesV the free end of one arm being adapted side pressure upon said member or knob will raise it suiiiciently against the tension of the spring j-lc, the length of the spring armj being sufficiently great to compensate for the side sway by reason of theeccentricity of the lug z'.

It will be observed that all of the operative parts of the vlatch mechanism are sup ported within box-like members, the supportsni` and Z, including the pull. In the assembling of the device, the only obstructions within the trame members will be the used Jfor attaching these supports which will be so clenched as to be substantially flush with the walls of the frame members. It will also be observed` that it is merely necessary to slide the end The tensioning of the spring results solely from the assembling of the box-like support with the frame member. When' the spring so disarranged `as to prevent its acting upon the lift member or knob to normally close same.

It is not my intention to limit the invention to the precise details of construction shown in the drawings, it being apparent that such may be varied Without departing from the spirit and scope of the invention.

Having described the invention what I FRANZ A. FULLER.
