ARCHITECTURAL COLUMN.

SPECIFICATION forming part of Letters Patent No. 453,341, dated June 2, 1891.

Application filed February 24, 1891. $erial No. 382,416. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOSEPH M. LARIMER, a citizen of the United States, residing at Ohicago, Illinois, have invented certain new and useful Improvements in Architectural Columns,-of which the following is a specification.

In carrying out my invention I preferably construct my column from two steel beams, preferably I-beams, although bulb-beams, Z- beams, and perhaps other forms maybe found well adapted. These beams of whatever form they maybe have their webs or body portions bent upon a curved line, so as that when two of them are placed with their convex sides toward each other the flanges thereof will present outwardly, and their middles are secured together by means of bolts or rivets through an interposed fillet or core of wrought or cast metal. This fillet hasshoulders to provide bearings for the beams on opposite sides 'of the connecting bolts or rivets. I provide, also, a continuous band or ring, which may be angular or plain in cross-section and adapted to form either a base for the column, a bracket to support and connect a transverse beam,or a part of the connection for a superposed column.

In the accompanying drawings, Figure 1 is a broken perspective view of a column of the preferred form of construction. Fig. 2 is a plan of a column of like construction to that shown in Fig. 1. Figs. 3 and are like views of modified constructions. Fig. 5 is a side elevation, partly broken away, showing the rings applied to the column; and Fig.6 is a plan view below 6 6 of Fig. 5.

A represents steel beams of the form known as I-beams, and which may be rolled in the first instance to the form shown, the webs thereof being centrally bent with reference to the faces of the heads. The form of the head or flange of the beam is not of the essence of the invention and the beam may partake of two types -as, for example, one head maybe of the flanged form shown in the drawings, while the other may be a bulb. These beams having their webs bent, as described, are then placed so that the heads of the flanges present outwardly and their convex sides face each other, and then, by preference, they are fitted to an interposed fillet or core B, preferably of steel. The fillet may consist of an I-beam,-as shown in Figs. 3 and 4, or of a solid block having its sides concave to conform to the convex sides of the beams, as shown in Figs. 1,2, and 6. The beams and fillet are then secured together by the bolts or rivets C. In this form of construction it is apparent that the weight is carried by the heads or flanges of the beams at the periphery of the column,while the webs and core or fillet furnish lateral or bracing supportto these heads or flanges. The result of this distribution of the weight is the prevention of shearing strain upon the bolts or rivets. The core or fillet, of course, adds strength to the column bysupporting orbracing the webs of the beams, and it not only increases the efficiency of the column in resisting a crushing strain, but also increases the efficiency for the resistance of lateral vibration or strain. Of course the size of the fillet will be varied in proportion to the length and size of the column. The fillet furnishes bearings on either side of the rivets, and the elasticity of the metal of the webs is constantly exerted in this form of construction to bind the parts "together.

I Ihe essential feature of my improvement consists in constructing the column from steel beams having their webs bent on curved lines and connected together through an interposed fillet adapted to furnish bearings for said webs at separated points and on opposite sides of the connecting bolts or rivets.

D represents a continuous ring, which may be angular in cross-section to provide a boltflange d and a supporting-flange d, and this ring can be either wrought or pressed to the desired form and utilized as a base-ring, as a bracket to support a transverse beam E or girder, or as a part of the top connection F to support a superposed column. This ring adds strength to the structure by clamping or confining the column members together when they are made from separate beams bolted through their webs.

Instead of specially preparing a fillet, it is obvious that an I-beam or double channel or two channel-beams placed back to back might be employed in place of the fillet shown, and, in fact, this fillet may be of any desired form in cross-section.
