To all whom it may concern.

Be it known that I, J 01m LALLY, a citizen in the county of Sufio-lk and State of Massuchusetts, have invented certain new-and useful Improvements in Column Caps 'or Basesof which the followin is a. specification, reference being bad t erein to the cc mpanying win This invention relates to column caps, the object in view being-to provide a cap or connection for columns and the several sec tions thereof, especially designed for fire-- proof construction, provision being made whereby the columns may be built up to any desired height and adapted to support the beams and rafters at the proper elevations.

With the above and other objects in view, the nature of which will more fully appear as the description-proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed. In the accompanying drawings :Figure l is a vertical section through a column cap embodying this invention, showing the same combined with a column casing or section.

omitted. Fig. 3 is a similarview showing a cup or' sectional construction. Fig. 4 is a top plan view of the upper or crown member of the sectional cap. Fig. 5 is a detail view of one-half of the body of the sectional cap. Fig. 6 is a vertical section i through a double cap, showing the manner of connecting adjoining column sections. Fig. 7 is a similar view showing the use Fig. 8 is a similar view showing a double detail sectional-view of a hollow or tubular anchor.

Referring to the drawings 1 designates the body of the cap, or, as it may be termed the lower cap member, while 2 designates the upper or crown member of the cap, and I it will be noted the upper and lowe'n members of the caps, both, have overlap ping and interfitting hollow or recessed bosses, the recessed portion of the body 1 being externally screw-threaded and the recess portio. of the crown member being internally screw-threaded to fit over the threaded portion of the body, whereby the up and down on the body by turning or revolving the crown member, for the pur-' pose of setting the beam or rafter support ing surface of the crown member at the desired elevation, 3 representing such supporting surface. The crown member 2 may be rovided with diametrical projections 4 with which a suitable implement may be engaged wherewith to turn said member and obtain the required adjustment.

- The construction above described is shown in Fig. 1, wherein it will also be sccu that the body 1 is provided with a downwardly extending annular flange 5 which enters the upper portion of the lower column section creasing 6. Under the preferred embodiment of this invention the flange 5 has on external dizunntcr sullicicntly less than the internal diameter of the cusing 6 to allow the filling of the casing and cap to enter and fill the annular space between said parts to assist in securing the cap to the column casing and making a solid column as a whole. The body 1 is also provided with an annular Shoulder or seat 7 which rests directly upon the top edge of the next lower column section or casing and in this way the threaded adjustment bo-' employ an anchor 9, one end of which passes through a hole in an anchor plate 10 ex tending across the inside of the body' l and rigidly connected therewith. the other eu-l of the anchor extending well down into the filling of the casing and having an enlargement or head 11 which is embedded in the. filling. The upper end of the bolt or anchor 9 may be secured to the anchor plate 10 by means. of a nut 12. It will be understood that the body of the cap is associated with the column casing before the filling is placed in position. The filling is put in in a plastic condition and hardens around the anchor 9 flange 5, and anchor plate 1O, tl1us securely binding the cap to the casing. The

crown member 2 may then he adjusted to 13 maybe substitutedtherefor, and in lieu Under each and allo'f the arrangements of theanchor shown in Fig. 1a tubular anchor 14 may be used as shown in Figs.

2 and 9, the same consisting of a suitable. .1 length of pipe one end of which is flared or swaged out as shown, at 15 to fit. into a. hole of corresponding shape and size' in the anchor'plate. At the other end the anchor thereon like an ordinary nutrifl To form a double cap or as it may be termed a'combined cap and base, two caps such as is shown in'Fig. 1, may be placed together in reversed position asshown in 13 :Fig. -7 andboltcd together through the rown plates as shown at 17.-

The cap may be of sectional construction as shown in Figs. 3, 4; and 5., in which it will be observed that the crown plate is 2 madseparate from the brackets 18. To this end 'the internally thremed part of the crown member is divided diametrically into two equal sections and said sections are pro-' vided with lateral flanges 19 which under-- 55 lie theplate and are fastened thereto as shownat 20, the said flanges 19 abutting .-on the line of division of the bracket sections, as shown in Fig. 4. In like manner the body l may be composed of twin sec 30 tions each in the form ofa hollow half cylinder, as shown ,in Fig. 5, said sections," when fitted into the casing, being firmly held thereby. The bracket sections' l8 will lordinarily he provided with holes tore- 3r oeivc connecting bolts 21. 4

If desired, a. double cap, or a combined 'capandbase, may beformed by providing the crown plate with bothupwardly and downwardly extending internally threaded 4o bosses, as shown'in Fig. 6, and these bosses may .he ofditferent sizes, as shown-in the same figure, to enable colii'mnsections or casings of different sizes to be connected up. Fig. -6 showsbeams 22, resting on the =15 crown plate oft-he combined cap and base. These beams may be secured by screws or bolts 23' passing through the crown plate into the beams, or said. beams may be fas- -tencd together and at. the same time to the column, by means of semicircular tie-straps 24, two of which are employed ateach' joint, ;each .passing half way around the column while the endsof the straps are extended laterally to rest against opposite sides. of

' 55 the beams to which they .are securely fastened by bolts 25- passing through the beams.

' Another way of making up a double cap,

or a comhinedi ca'p and base is shown in i igl 8 1n-'w h1ch a single crown plate 15 employed,

(so with sectional brackets 18 secured to the upper and lower sides thereof byibolts 26- or their equivalent.

14 may have a detachable head 16 threaded v :plate. between th beams or rafters may be accurately fixed;- .also that the, said adjustment is provided for without in the least impairing the strength of the parts of the column.
