JOHN LALLY, OF WALTHAM, MASSACHUSETTS.

COLUMN.

To all whom it mu/,I/ concern.-

Beit known that I, JOHN LALLY, a citizen of the United States, residin at Walthamin the county of Middlesex an State of Massachusetts, have inventeda certain new and useful Column, of which the'following is a speciiication, reference being had therein to t e accompanying drawings.

This invention relates to columns used in structural work, the object of the present invention being' to provide a novel form of connection or cap for columns the construction of which enables the same to be made out of wrought iron or steel, thereby adding greatly to the strengthaand durability of the column as a whole.

Afurther object of the invention is to provide aA cap v'or connection of sectional construction, whereby the several parts of the same may be the more readily made up separately and then combined to form a strong cap or connection especially ada ted for heavy work without increase of weig t inthe column itself.

A further object of the invention is to provide novel means for centering and `accurately and properly associating the parts of the column as a whole also, to provide novel means for anchoring or securing the cap `or connection to the casing and bracing the parts relatively to each other.

With the aboveand other objects in view the invention consists in the novel construction, combination, and arrangement of parts herein fully described, illustrated, and claimed. Y

In the accompanying drawings, Figure 1 is a vertical sectlion through a column embodying the present invention. Fig. 1 is a detail section showing a slight chan e in the centering-plate. 2 is a vertica section similar to Fig. 1 showing another way of centering the parts. Fig,I 3 is a similar view illustrating another variation in the form of the cap or connection. Fig. 4 is a similar view showing the entire cap or connection madein one piece. Fi 5 is a similar section showing a slight mo ification in the anchoring means. Fig. 6 is a bottom plan view of the sectional cap or connection. Fig. 7 is a top plan view ofthe base which rests u on the cap or connection to receive and ho d the upper casing or column section. Fig. 8 is a vertical section throu h the same, showing the manner in which t e said base is secured to the un- Specication of Letters Patent.

i Application tiled September 25,1906. Serial No. 336,160.

Patented Feb. 5, 1907.

In the drawings, 1 represents the columncasing in the form of a hollow, and preferably cylindrical, shell designed to receive a filling of concrete in a plastic condition, which hardens therein and forms a solid fireproof construction.

superimposed upon the casing 1 is the column cap or connection which embodies the beam-rest or crown-plate 2 and the reinforcingor, strengthening bracket 3, thelatter, under the preferred embodiment of the invention, being formed separately from the plate 2 and be' of sectional construction. To this endthe racket part of the cap or connection is constructed insimilarsections,

as shown in Fig. 6, in which it is seen that four sections are employed, each comprising an arcuate or segmental body part 4 and trian lar bracing webs or flanges 5, which in ma g u the cap or connection are fastened together ace to face by bolts, rivets, orthe like, as indicatedv at 6; Thebottom ofthe plate 2 is channeled or recessed to receive the top edges of the bracket-sections, as indicated in dotted lines at 7, said edges of the Section fitting snugly in the channels or recesses provided in the plate 2 therefor and the parts being held securely in the relation shown and described by the anchor hereinafter particularly described.

The anchor 8 consists of' a pipe or tube of any desired length, havingone end thereof swaged outwardor flared to form a head 9,-

and the plate 2 is, formed with a central countersunk opening 10, in which the head 9 tits and iinds its seat, the construction and arrangement being such that the outer surface of the head of the anchor lies flush with the top surface of the plate 2, as shown, thus provi ing for seating the superimposed base of the next higher column section or casing thereon. The anchor 8 extends down into the casin 1, where it is rovided with a suitable num er of bond-ho es 11 and when the casing and the hollow anchor are filled' with the plastic composition referred to said com- Iposition finds its way into' and through said oles, the filling of the casing combining and knitting with the filling of the anchor, and a number of bonds being thus formed which permanently fasten the anchor to the casing, while the anchor fastens the cap or connection as a whole in place on the casin In associating the parts hereina ove described a centering-plate 12 is interposed between the cap or connection described and IOO the to of the' casing' 1, and, as shown in 1 1, sai centeringeplate may be provided with l a fiange 13 at its outer edge, extending aboveand below the plate, within which the top edge of the casing 1 and the bottom edge of the cap Yor connection fit. The plate 12 is provided with a central opening 14 of suitable size to receive the anchor 8, and thus said Fig. 1, a flange may be located to lie within l the same arts, as shown at 17 in the detail section, Fig. 1a, the sai-d lastnamed flange answering the same pur ose as the flange 1,13. It is of course Wit-hm t 1e scope of this invention to employ both flanges 13 and 17; but this is seldom necessary.

If desired, the cap or connection itself may be provided with a flange 18, fitting into the upper end of the casing 1, as shown in Fig. 2, orwith a flange 19, fitting around the top of said easing, as Shown in Fig. 3. Under the arrangement shown in Fig. 2 a shoulder 20 is provided, u n which the centering-plate is seated, wh-i e' .under the arrangement shown in Fig. 3 said centering-plate is inserted between the opposingk edges ofthe casing and cap or connection and within the fiange 19.

In some cases the entire cap or connection mag be made 1n one piece, as shown m Fig. 4, an provided wlth 'an integral flange 21,

l within which the centering plate 12 lies,

' lcasing 28 fits, as shown in Figs. 7 and 8.

interposed between the casing and cap or connection. The centering-plate may have a harige '22 on butone side thereof, as shown in Fig. 5,- and the anchor instead of having the end thereof flared may be screw-threaded .to receive a retaining-nut 23, while the crown-'plate 2 may be recessed in its top face, as shown at 24, to allow thel said nut to lie within the plane of the top face of said plate, as shown in the same figure.

Where another column-section is to be set 'upon the cap or connection above described, I employ a base-plate 25, provided with hol-'es 26, which line up with the holes 16 of the late 2, so that suitable fasteners, such as lts, may be inserted therethrough to secure the base to the cap. Said base is provided 'with an 'u standing annular flange or hollow cylindrica body 27, around which the upper 29 designates beams or gil-ders which rest on the cap or connection, and 30 designates one of a pair of`s`traps which pass around the oppo site sides of the column and have their opposite ends bolted'or otherwise fastened to the beams or girders, as shown at 31.

Another important feature of the invention resides in the employment of a pin or dowel 32, one end of which extends down into -the anchor, and preferably to a po1nt below. the centering-plate 12, the other end extending up into the superimposed base of the upper lcolumn section or casing andas far as may be desired into the uppler caslng itself, where itis embedded in t e filling. Where the flare-ended anchor is employed, the dowel pin may be provided with a correspondingly-shaped conical vshoulder 355. to fit the flared end of the anchor, as shown 1n Fig. 8, and where the column is to be'subjected to special lateral Hor eccentric strain the outer surface of the pin 32 may be corrugated, threaded, or roughened, 'as indicated in said figure, to obtain a more secure hold upon the filling within the cap or connection and the casings.
