1''!) (11M w/wm, it our/y concern.-

Be it known that I, Enwxmn G. Bonn, a citizen of the United States, residing at Phil dclphia, in the county of Philadelphia State ol Pennsylvm'iia, have invented a cer' tain ne\ and useful improvement in i rmne Joints, of which the following is a specification.

The object of the present invention is to provide a joint l'or the meeting edges oi nietallic frame parts used in the construction of various articlesas, lor instance, ranseais, window and door frames, and the lil e---- which joint shall be of such character as ii) involve but little expense either of time or labor in its consl-uction, and which shall when in its completed lOIlD hold the connected parts rigidly together,making them in practical ell'ect integrah v Speaking generally, i employ in carrying out the invention frames of stomped. or pressed steel or other suitable material, each part thereof being made in sections, (preferably two in n umber whcre this is pructi =able,) the abutting edges of such sections being secured together in suitable uianner as, for instance, by Hanging the edge ol one over the flanged edge oi the otherand the adjacent edges ol' each such sectional frame member are over upped to form a joint and ti so cured, preferably bycrimpiug {he two thicknesses of metal into scnaintor-sleeres tending between the sections and serving the dual purpose ol bracing such sections to prevent collapse and through the crimping of the material into the interior of such sleeves securing the sections thereto and prevenling expansion. Any suitable number of such separators may be employed at each joint, varying with the size ol the joint and its cross-seclional configuration,' A metallic frame so constructed, in addition to beirg inconllmstiblc, possesses the desirable attributes ol lightness combined with adeqnziic strength, and also low cost as coinparec with other structures heretofore devised and even approafching the same ends.

The invention, while apaldeoi utilization for nurny and diverse purpoi parlicularly applicable to the construction of carseat frrnnes, and such application has been illustrated a will describ dhere out, however, the intent to in. it the invention thereto.

Turningnow to the construction of the sectional metallic frame more particu arly (3011' corned in the present invention, i promise, with the statement that the parts A A B B are or rna'y be substantially the same in construction, varying in the present instance only with regard to length. The invention is probably best .lisclose :l by l b to 6, in-- elusive, showing these parts on. enlarged scale. As here shown, each lower member of the sectional frame is formed of a single sheet, preferably of steel, stamped or pressed to the desired cr0ss-secti0nal shape. The body portion. i1 may be paneled or ribbed, as shown at I), either for ornamentation or additional strength, and the outer edge if is preferably turned inward near its extremity,

shown at b, for coaction' with the upper frame member presently to be described. The inner edge I)" is flanged inwardly at Ohio! similar coaction.

Each upper member A or A comprises the body portion a, which may also he ribbed or paneled, if desired, the outer edge (1, being perpemlicular thereto and the extremity thereof being turned over at a in a line par allel with the portion (0, leaving sullicient space between the portions a a, to receive the inwardly-turnml edge I) of the lower sec tion B or B of the frame. The inner edge of hobody portion. a of the upper section A or Al -of the frame is treated in the, same manner as the outer edge, save that it is not turned at an angle thereto. The extreme edge, as she 'n in Fig. 35, is folded, as at a, so as to lie in a plane parallel with that of the body a, leaving;,sullicient space, however, between thcifoldcd edge a, and such body to receive the inwardly-extending flange 6" ol the lower section, in pitwthc the channeled crossnzus C are riveted, as shown at c c, to these inwardly-pro'jcctino edges of the upper and lower sections of the frame, such rivets extending through the portioi s o, 7), and a, thus binding the same rigidly together. Said rivets will be employed whether the channeled bars 0 are used ornot, as they contribute to the rigidity and stiffness of the structure and oppose rending or distorting strains,

causing the connected members to move relatively to each other. Also the staples 0, whereby the (edge) coil-springs are secured in position, may extend tlnfough perforations between the corresponding frame parts extendin inwardly from the end members A" 3 of tie frame, thereby aiding in securing such corresponding parts ingot/hen, or, ii desired, for greater strcnuth said parts may be mom her A.

segues secured together by rivets in place of or in addition to such staples. v

Adjacent to the meeting edges of an end section and a side section a portion of the fold (L3 of each ol said sections may be cut away, as shown in Figs. 4 and ti, and the llange of one section overlapped upon the adjacent edge of the correspondingpin-t of the adjoining section, (the latter being preferably slightly depressed) the two parts b being secured through such overlapped joint by means of a rivet (1, extending also through the correspondingly-overlapped bony portiens a oi the two adjacent iranw-seclrons. Said rivet may be enrploycd whether the fold be cut away or not, or i nniy, it (i(Sll'(Li, utib ize for the same purpose U-shapeu cornerpieces 1:, as clearly shown in li'|;;.:l(). i.)

designates braces, each having the two members d. d at ri ht armies to each other and each member being perforated to receive a rivet whereby such member is SQCUI'Clh through the parts a, c", and b, as best shown in Figs. 3, 5, and (5.

Adjacent to its ends each member of the lower section B B ol" the frame provided with a lap-joint \vith'its cozzcting member of such. section, the material at the end of one such member bcmg suitably dc ressedin ordcr to permit the overlap by the end of the other member to lie in the same plane as the main. portion of the former. Thus in Fig. 4 I have shown the end member of the lower section B as provided with. depressions so arranged as to snugly receive the correspondingly-shaped end of the lower member B of the side section. This description holds true also of the several 1ll (?11]l)(.1$ ol the upper section A A of the frame. Thus in Fig. 2 l have shown one of the side members A as provided with de )rcssions a", reacting with correspondiugly-shaped portions .at the end of the upper member A. At the other corner {shown in Fig. 2) this is reversed, the de- 'prcssions being formed in the upper end member A and coacting with similarly shaped portions at the end oi the upper side The overlapping portions of the members A A of the upper section of the frame and. the overlap nng portions of the members B B of the lower section of the frame are thus arranged one directly above the other, and the same securing device, new to be described, attaches together not only the respective members of the ppcr section and the respective members ol 'tluilowe'r section, but also the upper and lower sections; Thus (see particularly Fig. 5) E dc. gnntes a separator-sleeve or section of tubing cl such len th as to abut against the znfjzu'ent feces of t io upper and lower sections between the or'erleps formed. in those sections and just described. fter the separator has been pieced in this position the material oi. each of grin/1 25 is secured therein either by a the same result will be accomplished.

. moi'iilica Lion ol' the separator structure above sea,

bolt or rivet passing through such material and separator-sleeve or by swaging or crimping such material into such sleeve. I prel'er and have illustrated herein the latter method, which may be l'ollowed with respect to each of said overlaps separately by means of a suitable tool, such as a punch, the material of the overlap lorming part of the upper section A A being thereby forced into the interior ol the sleeve anu the frame then turned over, and the material of the overlap forming part of the lower section B B correspondingly forced into the interior of such sleeve, or, if ('iLSllGti, the upper and lower sections may be placed together, the separators E in pro er position, and the whole frame laid over a suitable anvil containing a projecting stud or me, a corresponding stud or (he being placed over the overlap forming part of they upper section and pressure applied, whereby 1 Tbs may be done either before or after the use ol the rivets I) or of the braces l), the particular sequence observed being ol'minor importance. in Figs. 8, t), and 10 l. have illustrate1i a described, which, however, operates in the same manner not'only as a securing meiium winch additionally holds the frame-sections together, but also as a brace preventing col la se. Thus, as shown in Fig. 10, a casting may be placed between the frame-sections at the corners, su'ch casting having a plurality of ori'lices which may receive bolts passing therethrough and throu h the frame material or into which such material may lie swageil or crimpcd. in Figs. 8 and S) this s'eparator-castmg takes somewhat ill'erent form and is provided additionally with outwardly-extending arms whereby the separator 1s ell'ective throughout a greater space between the Frame-sections, bracing the same apart and greatly contributing to the strength and rigiuity oi the structure.

it will be obvious that the invention is not limited to the specific details herein de scribed and that the. structure specifically disclosed. may be departed from Within wide limits without saeriliee to the advantageous features of the invention. lhus, as an instance, it is not essential that the members of every section be provided with an overlap involving a depression in the end of one for coaction witii the end of the other, nor is the particular shape or configuration of the adjoining ends of two members of either section as herein described essential, an obvious departure from this being shown in Fig. 7. Indeed, the construction shown in said figure may be preferable Where the iirames are of considerable size and additional strength at the joints thereof is required, it' being possible to employ a larger number of separators or one of greater size and strength in this case and to swag-e or crime the material of the frame members into these by any suitable methodas, for instance, one of the two hereinabove specified. Also i desire it to be understood that the in ention is not limited to the use of the securing devices herein described only at the joints between the several members of the trance, as i may, if desired, secure greater rigidity intermediate of the ends ol the members by employing suchoverlaps, of a separator between such overlaps, the material of said overlaps extending into said separator, substantially as set l'orth.
