locking means and 6 for the tension members and channels, is subject te various changes, yWithout departing from the principle here involved. This form of connecting the tension rods to the liennels is effee'tive, and permits @quek Work in assembling the parts, andi does not diminish in any wey the strength of the material, as no holes are required for any rivets. By embedding such cennectio'ns in concrete they become permanent and absolutely seie, and will not loosen from shocker viloifetien; the concrete :ietf ing as an additional bond. to ineieese the strength and safety of the juncture.
The tension reds 2 may assume a. variety of shapes. n Fig. 3, I have shown them es `simi le diagonale hevin. one enfl. secured bo L lw ese channel A; an the opposiie end of the tensioni'ods secured w the opposed top elisnnel A.

lfiennflesoliitely rig-icl I-loeam structure is weniecl, l employ' e zigzag bei' 2', sie shown -otlie uppesed channels and locked therein bysniteblelieys, es 6. This structure prt deesse .truss beam ywhich een be adventigoiisly substituted. for the ordinary I- beelm in many instances, enl'witheut the use "eeoneiete, and it possessegf'ilfreadvantage of extreme lightness combinei' with great rlgid# ity.-
#Many of the advantages' of en l-beem are obtained by the design of Fig. 3 'Without the use of the 'zigzag bei' of Fie. e; ut in which Fig. 3, as loefere stated, the rods 2 are clesigned to resist tensional stresses. In the design of Fig. 4i, the compression strains are teken Careof, in'eddit'ion ojhe iensionall stresses. .In either case, the -loeam .slime ture resultin from the use of the anged channels simi ar to those of Fig. l, .permit-s the shape to be riveted directly to the steel columns in the identical manner of an I- beam,'so that it is made possible to have a reinforced concrete structure 'directly' riv' eted to a steel structure; something which has not heretofore been possible, as far as I am aware, with any otherv system. otI r'einbracket 8. In Fig. v7, I employ, inladdition to the angle bracket 8', the tension rod's 9 riveted to each flange 3 at one end, the other end being riveted to a bracket l() which in turn is riveted to the column 7 By this'systein of attachment there is permitted a minimum amount of reinforcing material, and yet there is aii'orded a maximum degree ofrigidity; and it is apparentv that once this attachment is made, and the beam vembedded in concrete, I get a rein-y forced concrete beam actually connected to the steel column without any special complication.
The points of advantage claimed for .the
present system are: the system o connection of the tension rods to the channel bars; the
use of the channels havinglateral iianges by which they can be riveted to a steel struc- I claim and desire to secure by Letters Pat' ture; and the combinationof a reinforcing structure riveted to a steel structure.
Having thus described my invention, what ent is I l. A structural metal shape including a longitudinal channel bar having the edges of the channel' inturned to inclose a space which is wider than the space between the intui'ned edges of the channel, a `diagonal bar tting .the channel, anda drive key for locking thc l saine in the channel, said key extending lon- .ykfgitudinally of the channel and inserted beside of thediagonal bar. l
2. A structural'metal shape including a longitudinal channel bar having the edges of the channel inturned to inclose a space which edges of the channel, a tension rod itting the channel, .said rod'within the channel having concaved sides, and keys fitting said concavities and locking against the inturned edges of said channel.
8..An I- beam structure comprising upper andlowcr spaced bars, each bar comprising a channel with lateral longitudinal flanges, connecting rods bent to fit within the channels and connected thereto, and drive keys -introduced-between the sides of the rods and inner sides of the bars. l 4. An I-beam structure comprising upper -and lower spaced bars, each bar com rising a channel with lateral longitudinal anges, and connecting rods bent to it within the channels and connected thereto, said' connections between said rods and channels producedjby keys fitting concavties in the o posite sides of the portions of the bars williin the channels and interlocking against the overturned edges of said channels, said cliannels' bein bent inwardly to produce said overturne edges.
Tliecbmbination of-a im tal column and alioi'izoiital reinforcin metal shape coinprising a horizontal c annel bar, tension members secured in thechannels of said bar, drive keys introduced between the adjacent sides of the channel bar and the tension members, and means for riveting said reinforcing metal shape to the column.
In-testimony whereof `I, have hereunto set my hand in presence oftivo subscribing witnesses.
