Fig. 1. In the latter -figurefoursuch'brackets are shown as having beenv secured together, the-horizontal surfaces of the several brackets thus constituting a `figure 'of generally :square outline. rThe composite .structure vthus formed is -nows yarranged 1in' ,the a slots 3, i4 at :the up-pe'rend :of the column', the contacting vertical ywalls ofadj acent brackets being: seated within the 'radially extending slots. The'cap'thus formedmay if desired 'be used withoutfurther modification, but 'it is preferred tosecure to the horizontal supporting surfaces of the bracket members la plate such as-26, which extendsover the several brackets, and forms. the-immediate As shown in Fig. 1 this plate may be square and of a size to overlap and cover support for the beam or gardera'I the recesses v20 vif such be formed in the outercorners of the several brackets. jThe cap thus constructed is symmetrical with respect to the axis of the column and is well adapted for supporting the ends of four beams or girders, or for supporting a single continuous girdery extending transversely across it, and the ends of two abutting girders.

In the arrangement shown in Figs. 3 and 4 a pair of the three walled brackets such ,as hereinbefore described are connected together by the rivets 25j, the'connected vertical' walls 18, 17 of such brackets being vseated-vv/*ithin a radial slot in the topl of the column. ,'Inthiscase, however, instead of connecting a second pair of similar brackets to the first named pair of brackets, an angle iron comprising the vertical flange 27 isjsecured tothe flanges 17, 18a of the 'axis of the post and is adapted to support ,the ends of three beams or girders abutting at the axis of the post or a single continuous -girder having the end of a beam abut-ting one side thereof. If desired this type of column cap may also be provided with a :supporting plate 30 resting upon the Awalls '14: andthe flange 29. f .":In the form of deviceshown in Fig. 5 a column ycap is formed substantially as shown .in .Fig f 3 `comprising the -three walled .brackets having the vertical walls 17, 1S secured together by rivets such as 31 and the amalis-,17 ;and1"8a being riveted toi-thc .depending flange 32 of an angle iron ha'ng the .horizontal flange .33. In this case, however,filiere-isnsecuredto the flange 32 'o1 the anglej iron the. cross bar 34 ofa Tvv iron .comprising the vertically disposed web 35 .Thelatter Amember. is received `within a slot Lin the rftopfof the post and serves as a brace or support for the flange 33. '-.In Fig. 7 the upper. end vof vthe post is -sliownas having' a .T iron comprising-blu --web' BGeXtending .transversely across the enc iofthepostandseated within a diametra slot therein, such iron `also comprising th( horizontal flange .37. In this case the flange .37 is' unsymmetrical -with respect to thf :memberf36, l' and vassociated with the longe] portion thereof is a T iron comprising th web 38 andthe cross bar 39, the latter be ing connected' by means of .rivets 40 to tlr fla-nge '36. The member 38 thus serves t support the unsymmetrical overhanging portion of the T iron whereby to strengthei .that portion of the .capl upon which th greater part of the weight will rest. Sup porting plates 41 and 42 respective-ly ma] be associated with the caps shown in Figs 5 and 6, Z and 8 respectively if desired.

7While as herein illustrated the columi has been shown as provided with slots ar ranged vto intersectat right angles with eacl ..other, it is .to be understood that the slot "It :is alsofto'beunderstood that variou changes and modifications in the shape am relative dimensions of parts might Well b made without departing from the spirit o the resent invention.

' avi-ng thus described the invention, to

gether with the mode of use thereof, what I claim and desire to secure by Letters Patent of the United States is:

l. A column cap comprising a plurality of three walled brackets 'formed from structural iron and arranged with one Wall of each bracket in contact with a Wall of the other, and With the third Wall of each of said brackets lying in a common plane, and mea-ns for securing together said contacting Walls.

f2. In combination With a column provided with a pair of diametral slots eX- tending a-t right angles to one another, a column cap comprising a pair of three Walled brackets formed from structural iron, one Wall of each of said brackets being disposed in contacting relation Within one or said slots, a second Wall of each of said brackets being disposed Within another of said slots, the third Wall ol each of said brackets lying in a common plane.

3. In combination With a column having a plurality of radially extending slots in its end, a column cap comprising a plurality of like brackets, each having three Walls, two of said Walls being vertically disposed, and the other being horizontal, and means securing a vertical Wall of one bracket to a vertical Wall of another, such connected pair of Walls being disposed within one of said radial slots in the column.

4. In combination with a column having a diametral slot and an intersecting radial slot in its end, a column cap comprising a pair of three Walled brackets each having a vertical Wall disposed in said radial slot and in contact with one another, and each having a second vertical Wall disposed in said diametral slot, said last named Walls being in alignment, and an angle iron having one iange also disposed in said diametral slot and having its other iiange lying in the plane of the third Walls of said brackets.

5. In combination with a column provided with a pair of axial slots in its end, a pair of three Walled brackets, a Wall of each bracket being disposed in contacting rela tion within one of said slots and a second Wall of each bracket being disposed in alignment in the other of said slots, a plate like element also disposed in the latter' of said slots and secured to the aligned Walls of said brackets, and a T-shaped member having its cross-bar secured to said plate like element and its other member arranged Within said first named slot.

6. A column cap comprising a plurality of three Walled brackets, each comprising a horizontal Wall and two vertical Walls, means for securing a vertical arm of one bracket to the adjacent Wall of another bracket, and a plate contact-ingh With and secured to the horizontal Walls of the several brackets.
