Application filed June 28, 1908. Serial No. 189,918.

, tion in detail it'may be employed in the con struction of hames of other types.

In the accom anying drawings, Figure I is a view in si e elevation of a hame, the portion of the filler shell within the main shell being indicated in line. Fig. II is a view 0 the same, in ed e elevation, si ht being taken t ward'the rig t hand side 0 the structure of Fig. I. Fig. III is a longitudinal sectional elevation on the line III--III of Fig. II. -Figs. IV, V,

VI, and VII are sectional elevations of the structure, sections being su posed taken for the res tive figures on t e lines IV-IV,

V-V, --VI, and VII-VII, respectively.

Similar letters of reference indicate corresponding arts.

The y of my improved hame is in the preferred embodiment of my invention illus trated in the above mentioned drawings produced by the union of two metal shells each trough gutter or U-shaped in transverse section. one of which I term the main shell, a, the other the filler shell, d, arranged with their concavities' in opposition and with the side walls of the one extended between and in'lateral contact with those of the other. In. the arrangement depicted the walls of'theoneshell overlie so to speak those of theother, so that the wall edges of thefone shell are out of registry'with the wall edges of the other.

In practice the shells, which are preferably made of steel, maybe conveniently stamped by dies or hammered :Eromv suitably flat stris into the axial conformation and tron -sha section required.

she embodies the usual outwardinward axial curves at its a r and er shell profile by a dotted filler shell is design embodies an axial inward curve at its lower end.

The curved axial line of the com leted hame is in a' plane which is in paral elism with the side walls of the shells at the central part of the heme, and, as seen in Fig. I, the basal portion of the filler shell forms the concave or inner face and the basal portion of the main shell the convex or outer face of the curved region in the lower-part of the, hame. While both of the shells areof a' general trough or U-shape' in transverse section, each, in the preferred embodiment illustrated, has a special further conformation, as follows: The body of the main shell is for a suitable distance as to its basal wall flat from edge to edge, that is to say, in

transverse'section said wall exists in a plane at a right an 1e with res ect to the side walls 6, c, of t e said shel and Said basal wall is in the assemblage of the shells encountered by the edges of the side walls, 6, f, of the filler shell, d, the contact of said side -walls with said basal walk-which latter serves so tospeakas astop for thefiller shell,-maintaming the parts in position against displacement by external pressure on the base of either shell.

The filler shell in transverse section is as to one wall, e, a proximately straight from edge tobase, an as to'the other, 7, straight as to its outer 'onedge re ion and in substantial parallelism with sai wall e and curved as to its basal region, so that it externally approximates the form of the wooden filler b ocks hitherto em loyed, and which the e to replace; Both walls of the filler shell 'radually increase in height from their en s toward their central portions, as shown more particularly in Fig. I. The shanks of a staple, g, a bolt, h, the outer end of which carries a line ring, '2', and one shank of a staple, j, extend as rivets through both shells, and being upset at their inner ends, secure the shell members firmly together, reinforcing the hold of the main shell-upon thefiller shell. f

The opposinqedges of the end regionsof the mainshell as distinguished from the body region are brou ht together as shown in Fig. IIi so that said end regions areapmain shell to supportthe eye below said" shell.

'Aswill be observed, especially from Figs.

I IV, and VII theside'wall c of the main shell is, where the arrangement and proportions of the parts permit, bent as to lts outer edge slightly inward'to follow the conformation of the curved Wall of the filler shell.

The shells are :--;i'a1n1'=ed out with great.

rapidity, and, being shaped in forming dies,

the desired COnfigLH'fitlC-ll may be imparted with accuracy, and the -ormed shells quickly and easily assembled. The completed structure is strong and durable even though comparativelythin metal be used in making. it.

In the preferred embodiment of vmy invention illustrated, the walls of the main shell are,'inthe region of the deeper portion of the hame, for example the region between the section lines VV and VI-VI of Fig. 7

I, in transverse section, approximately parallel and perpendicular to the base ot said shell, and also, in the same region, the portions of the walls of the filler shell in the vicinity of the outer edges of said walls (being the edges which are in the assembled position of the parts adjacent to the base of the main shell)*are, in transverse section, approximately parallelism with each other and with the walls of the main shell which their side. faces confront or oppose;

at points in the vicinity of the ends howeverthe sidewalls of the main shell gradually merge into the substantially annular form of said ends. lVhen in the claims I referto walls as being straight or flat, it will be understood that the phraseology covers such reasonable variation tromflmathematical accuracy as the form of the heme manufactured and convenienceot manufacture may dictate.

Having thus claim and desire to secure by Letters Patent:

1. A metal filler shell for-a hame, approximately trough shaped in transverse section and having side walls of-tubstantially equal height one wall being substantially; straight from-edge to base and the other curved as toitsbase. .i

2. A metal filler shelljtor-a l1ame,-the same-being approximately trough shaped in transverse section and having side walls of substantially the same height one wall being approximately straightfromfedge tobase described my invention, l.

.3 A hame comprising amen main shell, having suitably arranged end regions and a central body which is approximately trough shaped insection, and a hollow metal filler, shell arranged within said central body and extending substantially from end to end thereof, with the exterior faces of the side bases of the same. i

5. A hame comprising a metal main shell having suitably arranged end regions and central body which is of approximately trough shaped cross section, and' a hollow metal iiller shell arranged within said central body and extending substantially from .end to end thereof, with the exterior faces oi the side Walls of said filler shell opposing the inner faces of thewalls of the main shell, said central body havinga curvature in its length the basal portions of the respective shells constituting the respective faces of such curved convex and concave portion.

6. A a main shell and a filler shell, both of metal,

hamethebody of which is formed elf I and approximately trough shaped in transverse section, arranged and secured with of'thetwo shells mutually overlapping with the edges of the one shell out or registry with the edges of the other. a

7. A hame the hollow central region or body of which comprises'a main shell and a filler shell, both of metal, and both approximately trough shaped in transverse section, arranged and secured with their eoncavities 1n"opposition,' the side walls'of the filler shell extending between the side wallsof the main shell with theedges of the walls of the main shell out of registry with the edges of the walls of the filler shall,

a provision.- for limiting the inwardmovetheir concavities in opposition, the side walls ment of the filler shell within the main shell, 7

andwthe" end regions of which hame include portions of the mam shell wh ch extend beyond the filler shell.

8. Ahame the body region of whichcozuprises a hollow metal main shell and a hot low metal filler shell both approximately trough shaped in transverse section, saic main shell having a base which ts 111 'sectior at approximately a right angle with respectv to its side walls, which shells are arranged and secured with their'concavities inoppo sition, and with the side walls of the tiller shell between those of the main shell and.
