" ee 01* forged metal zinditand the body ztlei igidl'y uiiit'ed by the eastingof the east )odfyuponportions of the forged metal The body, is in one integral casting met-lion of Let flange 16 extending the entire lengtli'of the ilat condition, and there its transverse central poi'tioii' is bent outrs Poteht. i Patented and the heel" 11in one iiitegi'al plate extendin nearly the entire. length and Width of said body. llihe book '11 is formed. at its trailsverso een rel portion with a hox-ioop OI l e lug 3.3, at its en d portions with inwardly 42x tending transverse loops it, at one edge termediate the-box loop 13 and loops 14 with beveled sections 15 and at its other edge'portion with an. outwardly euived or arched hack and engaging the of the body 10.
The novel features of myihventioh tails iiioz'e particularly to the i for ei: oiently scouring the thing 1'5 of the loop or key-lug i3 and iz'iwardiyextending tmnsve'rse loops 1%- being fully shownend described in Letters Patent No. 854,985 granted May 28, 190-7 to Seth AfCi-one.
The flange 16 is formed, at about its trans-- verse middle portion, with. an inwardly projeoted tongue 1.? and above and below seid tongue with vertically elongated slits Whose Walls are preierahly spi'eadone on;
slits 18 but when the: of the speoial "term and construction shown. and desorihed herein they i'eoeive portions of the metal of the flange 12 and i'iimly unite the flange 16 their m x e 11d spread-slits 18 are for Do. who nlete ii iii miich the book 11 is formed is in its let condition, said tongue being of dove-toil outliiie at its free end portion. 19 and united with the outer portions of the flange it} by an outwardly diverging section 20 (Fig. D said tongue thus being connected Withthe flange 1G by it substantial extent of met-2:1"andcreeting at its'u ppei' and lower edges eneng ulei' forms. tion at the contiguous portions of the parts 1.9, 20 to receive and form a. look with the y'east'metel. The plate is out on three ooiineoted lines to fcziii'i. the tongue l; at time when, asabove desorilied, plate in its 1 said plateat 'war-dly to fol-m the hoxdoop or key-lug 13,
this resulting in theldrawing together, to
' some extent, of the o ening' leftby the cutting and depression the tongue 17, whereby the upper and lower edges of said opening are, as shown in Fig. 1, drawn toward each I other and the opening becomes less in vertical widflr than the vertical width of the free end portion 19 of the said tongue, said portion 19 being,
which it was out after said. upper and lower side edges each other by the operation of forming the box loop 13.
The cast metal covers the inwardly ro-* 0 ening has its jected'tongue 17 and not only forms a ock above and at the edges of said tongue, but
extends above the same and between the upper and lower inner end portion of the tongue and the inner surfaces of the ba ck plate where the latter has been drawn inwardly at the up er and lower edges of the ipening from WllCll the tongue was cut.
leaving the upper and lower edge portions of I the tongue extended upwardly and down' wardly beyond the edge vportions of said opening. Y j I f I have referred to the ton ue 17 as being cut from an interior portion of the back plate, because said tongue extends in an inwardly direction from the side edge portion of the plate and does not extend outwardly through said edge, leaving the edge portion of the plate about the outer end of the tongue 1n its integral condition, which I also consider advantageous. The slits or openings 18,
above and below the tongue 17 are also formed when the metal for the back is flat,
and these slits 18 arecuts through the metal,
none of the latter being removed, and in the finished article become of special character since the outer side wallsof the slits "are pressed outwardly or s read so as to form concave outlines 21. T. 1e outwardly spreading (awe side walls of the slits18 results in ,/the"' uter edges of the flange 18 adjacent to said slits being moved outwardly on convex lines, as at 22. After the slits 18 have been cut and,:1their walls spread, the flange 16 is arched er curved, as shown in Figs. 1 and 5, to suitably rece ve the flange 12 of the body 10, and this arching of said flange results in the edges of the sl t-openings 18 becoming rawn toward.
as shown in Fig. 1, of greater vertical width than the opening fromset on inclined-lines so that they operate as,
beveled surfaces to receiveand lock between them portions of the cast metal, the outer edges of said slit openings being-wider than f the inner edges thereof and the walls of said openings being thereby enabled to effectually. tie the cast metal flange '12 to the flange 16 of the back plate.
I do not wish to limit the invention, in
' everyinstance, to the formation of the, 100k".-
ing openings-18 by first slitting and spreading the metal, as just above described, and then arching the flange 16 so as.to jform beveled edges at said openings, but prefer said construction because 'Of its efliciency and the fact that none of the material of'the back is removed in the formation of said openings. The-body 10 is in one integral casting and the back 11 in one integral plate and said.
body and back are united together by the cast metal flowing and solidifying upon the transverse lo0ps,14, beveled edges 15, central lips 23, tongue'17 andedges' of the slitopenings 18, the flange portion 16 of the back being united'with the flange 12 of the body portion 10 more especially by-the' cast metal which engages the-tongue 17 and entersi'the slit openings 18, but. being additionally secured by being integral with the main portion of the back plate and the features referred to for uniting the'main portion of the back late to the main portion of the body 10.
hecentral lips' 23 are created in the forma 'tion of the box-loopor key-lug 13 and are disclosed in my aforesaid Patent No. 854,985.
