To all whom it may concern:

Be it known that l,A JOHN LALLY, a citizen of the United States, residing at Waltham, in the countyof Middlesex and State of Massachusetts, have invented a certain new and useiul Column, oi which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to columns, and the object of the invention is to provide a simple and effective union or combined cap and base 'whereby the members or sections oi a sectional column may be securely coupled together.

A further object of the invention is to provide coupling means of the character above referred to which will enable the column sections to be filledwitha plastic composition and thereby rendered fire proof and adapt'- ed to sustain enormous pressure.

A further object of the invention is to provide coupling means of the character referred to by means of which the sections of the column when filled withl plastic composition will be securely and firmly anchored or vof which will more ully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as hereinafter fully described, illustrated and claimed.

In the accompanying drawings: Figure 1 is a vertical diametrical section through a column embodying the present invention. Fig. 2 is a sectional'plan view of the same. Fig. 3 is a reduced sectionv similar to Fig. 1 showing some slight changes in construction, but involving the same principle. Fig. 4 is a similar section showing the combined column cap and base'formd integrally, Fig. 5 is a similar section showing a modification in the construction of the lower end of the upper column section"` F ig. 6 is a sectional plan viewl oi the arrangement shown in Fig. 3. i

The preferred embodiment of my invention is clearly illustrated in Figs. 1 and 2 in which 1 designates what we will term the upper column section and 2 the lower column section, while 3 designates the main body portion of the combined cap and base. It may be stated at this point that a column maybe made up of any desired number of sections 1 and 2 with the complemental unions consisting ofthe combined column cap and base to be herein particularly described. Each of said column sections may be of any suitable length and is in the form of a tubular metallic casing the major portion oi `which is designed to be filled with a plastic material which subsequently hardens within the column'section and renders the .same solid throughout and fire proof.'

The main body portion of the union is of cyl indrical form as indicated at 3 in Fig. 1 and may beoi any desired height, but preferablyof the same diameter externally as the column section abutting against the same.

At its lower end, the body of the cap ior the lowerl n column section is provided with a flange 4 annular in shape and ofi-set inwardly sufiiciently to, allow an annular key space 5 betweenthe inner wall of the column sectionand the outer surface of said flange as clearly y shown in Fig.` 1, and the outer surface of said ange 4 is corrugated or ribbed and grooved as shown so that when f l the plastic composition hardens between the column section and said fiange, it forms a key or bond which anchors the column cap to the column section 2. By offsetting the flange 4 inwardly as shown, an additional'annular shoulder 6is provided within the cap 3 which also obtains a rm hold on the plastic lli'ng. In this way the cap and underlying column section are firmly bondv ed and tied together.

In its upper portion and outer face, the head portion 7 of the cap 3 is provided with a recess 8 adapted to re.-

ceive a nut 9 screwed upon the upperextremities of an anchor 10 which extends downward within the cap 3 and into the underlying column section 2, said anchor being in the form of a bolt or rod as shown in Fig. 1 provided at one end with an enlarged head or flange l0 which becomes embedded in the central portion o the plastic filling and serves as an additional means for fastening the cap on the underlyingcolumn section. If desired, a clamping or lock xnut 11 may be placed upon the anchor l-beneath the top 7 thereof'so as to vhold the anchor fixed and centrally within the cap. It

member of the union which comprises a body portion or base 13 preferably secured to the top of the cap by lag screws 14 which pass through openings in the projecting corners 15 of the base 13 and into threaded sockets in the cap as indicated in Fig, 1. Extending upward from the base orbody'13 is a flange 1G which is of less diameter externally than the internal diameter of the ad- 4 jacent column 1, .the flange 16 correspondingin all particulars with thefiange 4 of the cap 3 hereinabove particularly described, the s'aid flange' 16 having its outer posed column section enters between said column sec-l tion and the corresponding iace oi the flange iii, forming a bond or key which secures such column section to the column cap and base.

posed combined column cap and base. Extending laterally and horizontally outward from the caps 3 at one, two er more points are beam rests li) upon which the inner adjacent ends of iloor beams or rafters 2O are stipported as shown in Figs. l and 2. The rcsts 19 are reinorced'by bracing webs 2l. which, in Figs. l. and 2, are shown as extending from the rests i9 upward, heilig connected to the cap 3 or formed integrally therewith.' The bracing webs 2l are also shown as preferably provided with extensions or lugs 22 through cach pair oi` which is inserted a bolt 23 which passes through the web of the adjacent eye beam 2() as best shown in Fig. 2, spacing sleeves or washers 24 being interposed hetween the bracing Webs2l and the web the beam 2O and around the bolt 23, thus securely holding the beam i to the column and preventing the possibility of any lateral niovement or vibration of said beam relatively to the column.

The construction illustrated in Figs. .3 and G cmbodies the lsame principle as that hereinabove described differing therefrom only in certain details oi shown as extending downwardly instead o1' upwardly. Another' difference resides in placing the cap plate 25 upon the upper edge of the/[lange i6 i'or the purpose 'ot' preventing the plastic filling from passing around and holding the nut 9 of the anchor 10. In order to secure the cap plate 25 in place, another anchor 2G similar in every .respect to the anchor l0 hereinttovc described, may be associated with the cap plato 25 as clearly shown in Fig. 3, anchor 2G being disposed reversely to the anchor li), with the enlarged head therwf upward.

Instead of forming the flange i6 separate i'rom the cap 3 and securing said parts together, the said parts may be integrally formed as shown in Fig. 4. An additional fastening means is illustrated in Fig. 5 in which the inner face of the cap is shown as provided at intervals with inwardly exondiiig key projections 28 which bocome embeddodlln the plastic filling. It is also contemplated to secure a reinforcing cup in the lower end of the superimposed column section 2 as shown in said Fig. 5, said cup embodying the imperi'orate base portion 29 and the annular side portion 30 which i its snugly within the lower end of the column section--lZ--and over In this way the adjacent column Y sections are securely fastened together' by the interconstruction. For instance, the bracing webs 2l are 'i l l l i l l l ing the same true, preventing the same from bending,`

and at the same time serving as a guard to prevent the plastic filling from covering and burying the nut 9 of the anchor l0. Preferably the cup iits snugly around the ange 16 and thereby acts to enter the upper column section with reference to the combined column cap and base.
