Application filed July 27, 1904. Serial No 218,382.

T iis invention relates to columns, and has particular reference to the caps and bases of columns, the main object of the invention being to provide a cap for a column embodying novel means whereby the cap is firmly secured to the column and also adapted to en port overhead beams or girders and secure y connect the same to the column, the cap be ing adapted for use either in connection with two-way, three-way, or four-way beams or girders.

A further object of the invention is taprovide What may he termeda combined cap and base which will not only provide for the support of. overhead beams of girders, but which also adapts the su eriniposed sections of a column to be unite and securely coupled together.

It is also an object of the invention to so construct the combined base and cap that the parts thereof may be used conjointly or so arately, as may be required.

ith the bove and other objects in view,

the nature of which will more fully appear as the description )roceeds, the invention consists in the nove construction, combination, and arrangement of parts, as herein fully described, illustrated, and claimed.

In the accompanying drawings, Figure l is a side elevation of a sectional column, showing the combined cap and base connected therewith and sup orting four-way bee ms or.

note the upper and lower parts or sections of a column, each of which consists of an outer shell or casing 3 and an inner filling e of concrete, cement, or analogous composition, with which the shell is filled while said composi- .tion is in a plastic condition, the composition being allowed to harden, thus impartin f great strength and Austin and fireproo'i quell ties to the column as a w ole.

in connection with. the column 'sectionsl employ a combined cap and base or, in other words, a combined column coupling and beam-support which in the preferre embodiment of the invention (shown in Figs. 1,

Referring to the drawings, 1 and 2 dcsig- 2, and 3) comprises a cap which fits, upon the upper end of the lower column-section and a base which fits upon the lower end of the up per column-section, sis-clea ing shown in Fig. 2. The cap comprises an a utting plate 5, which rests upon the top of the lower column, section, and a tubular flange or sleeve 6 which surrounds the u per portion ofsai column-section, while t e case comprises an abutting late 7, which extends across'ths bottom 0 the upper columnssection, and atubular flange or sleeve 8, which surrounds the lower portion of the upper column-section, Y

as-clearlyshown in Fig. 2.

The'cap may be securely connected to the lower column-section by means of an anchor, comprising a bolt or rod 9, provided at its lower end with an enlargement or head, such as is shown at 10 in Fig. 5, the said bolt and head being placed in the column-shell before the latter is filled with the plastic c'omposition, the latter 'subsc uently hardening around the bolt audits 1 sad, and'thereby firmly retaining the latter in place." The abutting plate 5 is provided .withan opening to receive the extremity of'the bolt or rod 9 I and is also recessed to receive a hut 11 or its equivalent, which being laced upon the rod or-bolt serves to fasten-t e cap to the lower column-section, as clearly shown in Fig. 2;.

In addition to the anchor 9 tie-bolts 12 ma be passed through the fia'n es 6 and 8 an also thron -h the column-chem 3 and also thro h the filling 4 of the column-sections,

log

the said bolts serving to tie the cap and base to the column-sections.

'. The butting platesand Y emirates ward beyond the flanges e and 8, as shown in I Figs; 1 and 3 and also shown by dotted lines "as to lie directly beneath the in Fig. 2, and said extended portions of the plates are provided with openings to receive a series of tie-bolts 13, by means of whicn said plates are firmly secured together, thus complcting the coupling of the column-sections them to support the lower edges of the beams or girders, which are shown in the form of T-beams 16. The projecting portions of the abutting plates 5 and 7 are provided at diametrically opposite points with radial slots 17 toreceive the webs of the I-beams 16 and allow the ends of the beams to fit snugly up against the flanges 6 and 8 of the--combined cap and base, as shown in Figs. 1 an l 2. The base is also provided with outwardly-projecting saddles 18, arran ed in pairs, one pair for each T-beam or gircer, as shown n Fig 1 and 3, the upper ends of said saddles lying directly under and in contact with the upper flanges of the I-beam, as best illustrated in Fig. 1. The saddles 18 extend from the abutting plate 7 upward, and saddle extensions 19 are formed on the flange 6 of the base so upper portions 18 of the saddles, and thereby assist in bracing and supporting the u per portion of the I-beam or girder, as will clearly appear in Fig. 1. The saddles are also provided with outwardly-projecting lugs 20, through which are passed bolts 21, which also pass through the up er flanges of theI-beams, the I I-beams or gir ers being thus firmly connected to the combined cap and base, and therefore to the column.

Figs. 1 and 3 show the combined cap and base provided with saddles and stirru s for four-way beams and girders; but it will be obvious that where one or two beams are con nected therewith the number of saddles or stirrups may be correspondingly reduced under the construction illustrated in Fig. 3, the said saddles and .stirrups being formed integrally with the base and cap members.

In Figs. 4, 5, and 6 I have illustrated another form of combined cap and base, which, however, involves the same principle. It will be observed by reference to Figs. 4 and 5 that a single abutting plate '22 is employed and that the upper and lower sleeves or flanges 23 and 241, respectively, are formed separately therefrom, the lower sleeve being secured to the abutting plate by means of angle-brackets 25, bolted, riveted, orotherwise secured .to the sleeve 24 and the abutting plate 22. If desired, the bolts 26, which secure the angle-brackets to the sleeve 24, may extend entirely through the lower column-section and its filling. Where one and two way beams and tying overhead beams or era-see as shown at 29, and similarly connected with the web of the beam, as shown at 30, each saddle comprising a portion which lies directly against the sleeve 23, another portion which lies directly against the web of the beam, and upper and

lower portions

31 and 31, which conform to and bear against the upper and lower flanges of the beam, as 0 early shown in Fig. 4.

Instead of employing the stirrups 14 (shown in. Figs. 1, 2, and 3) angle-brackets 32, similar to those 25, shown in Figs. 4 and 5, may be employed, as illustrated in Fig. 6, in which case said angle-brackets 32 will be bolted, riveted, or otherwise secured, as shown at 33, to the bottom flanges of the I beam. In this way the beams or girders are firmly connected to the cap and base at both top and bottom. a I

The construction above described provides for firmly connecting the upper and lower sections of the column and also supporting girders where they meet the column. It will of course be understood that where there is no superimposed column-section the cap will be employed and the ceiling beams or rafters connected thereto.

The cap and base in any and all cases may be made in one solid piece, if desired. The sleeve 24 may be made in sections riveted to the shell of the column instead of in the form of one continuous sleeve, while the sleeve 23 (shown in Fig. 4) may be cast with the bottom'plate in one solid piece, thereby doing away with the brackets 27 The bolts 26 may pass through the brackets 25, abutmentplate 22, and lower portions 31 of the saddle (indicated in Fig. 4) thus adding greatly to the strength of the structure as a whole.

Having thus described the invention, what is claimed as new is 1. A combined cap and base for columns comprising an abutment-plate, sleeves or flanges extending upward and downward therefrom, means for securing the sleeves or flanges and abutment-plate together, and oppositely -arranged saddles pro'ecting outward from the upper-portion of the combined base and adapted to underlieand' support the upper flanges of I-beams or girders.

2. A combined cap and base for columns comprising an abutment-plate, sleeves or flanges extending upward and downward therefrom, means for securing the sleeves or flanges andabutment-plate together, stir- 'tie bolts passin rups pro'ecting outward from the combined cap and ase tit-support the lower edges of the beams or girders, and saddles projectingoutward therefrom to support the upper portions of beams or girders.

3. A combined cap and base for columns comprising an abutment-plate, sleeves or flanges extending upward and downward therefrom, means for connecting the sleeves or flanges. and abutment-plate, saddles extending outward from the combined-cap and.

base to support the upper portions of beams or girders, said saddles extending upward from the abutment-plate, and saddle extensions 'extending'downward from the abutment-plate in,line with the saddle member.

4. A combined cap and base for columns comprising an abutment-plate,'s1eeves or flanges extending upward and downward therefrom, beam or girder supports extending outward r'rom the sleeves or flanges, and through said sleeves or flanges above an below the abutment-plate and adapted to pass also through the ends of column-sections inserted within the sleeves or flanges, for fastening said parts together.'

5. A combined cap and base for columns comprising an abutmentplate, sleeves or flanges extending upward and downward therefrormsaddles extending upward from the abutment-plate and adapted to support the upper flanges of a beam or girderplugs extending laterally from the saddles, and

bolts passing through said lugs and flanges 5 of the.I-beam.

6. A combined cap and base for columns comprising an abutmentplate, sleeve'sor flanges extending upward and downward therefrom, means for securin the ends of the 4o column-sections within'said s eeves or flanges, the abutment-plate extending outward beyond the sleeves or flanges andbeing rovided with one or more radial slots to a mit .the web of an I-beam, and meansjfor su porting an I-beam or girder and. securing't e v same to-the combined'cap and base. v

7. The combination 'of tubular metallic column-sections, of a'combined column cap and base comprising an abutment-plate fit- 5b ting between the 0 en ends of the sections tubular flanges or s eevesextending upward.

and downwardfrom the abutment-plate and entirely surrounding the end portions of the column sections, means for securing the 55 parts'of'the column cap and base together,

and means on the combined cap and base for su porting horizontal beams or girders.
