POST-CAP.

Application filed April 3, 1905.

Specification of Letters Patent.

Serial No. 253,707.

To all whom it may concern:

Be it known that I, JAMES CRAIG, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and metal layer between two superimposed posts.

The primary object of this invention is to provide a composite post-cap which is simple and inexpensive in construction, which possesses the requisite strength and durability, and whose component parts are conveniently and quickly assembled.

With this object in view and to the end of realizing other advantages hereinafter appearing, this invention consists in certain features of construction, and combinations of parts, hereinafter described and pointed out in the claims.

In the accompanying drawings, Figures 1 and 2 are two vertical sections taken at a right angle to each other and illustrate the application of a post-cap embodying my invention. Fig. 3 is a top plan of the postcap detached. Fig. 4 is an end elevation of the post-cap. Fig. 5 is a side elevation of the post-cap. Fig. 6 is a bottom plan of the post-cap.

Referring to Figs. 1 and 2 of the drawings, A indicates a lower vertically arranged supporting post; B, an upper post arranged ver tically above and in line with the lower post A, and O, my improved post cap which forms a metal layer between the two posts A and B and is mounted upon the lower post. Two joists or horizontally arranged beams D are supported from the post-cap at opposite sides respectively of the upper post B. The lower;3 post A is shown thicker than the upper 0st p My improved post-cap is shown detached in Figs. 3, 4, 5 and 6, and comprises two superimposed horizontally arranged metal plates G and K. The lower plate G is adapted to rest upon the lower post A and is provided with two depending parallel flanges 9 extending longitudinally and from end to end oi the plate and adapted to abut against opposite sides respectively oi the said post. The plate G is long enough to extend in under the horizontally arranged joists or beams D which are to be supported from the lower post A. The plate G extends, therefore, upon the application of the post-cap as shown in Figs. 1 and 2, longitudinally of the said joists or beams a suitable distance, with the two flanges 9 extending a suitable distance longitudinally of the joists or beams D and arranged at opposite sides respec tively of the lower post A.

The upper plate K rests upon and extends longitudinally of the lower plate G. The two plates G and K preferably correspond in length. The upper plate K extends therefore, upon the application of the post-cap as shown in Figs. 1 and 2, in under and longitudinally of the joists or beams D a suitable distance and is arranged also next in under the upper post B.

The upper plate K is provided with two upwardly projecting parallel flanges is extending longitudinally and from end to end of the said plate and arranged at opposite sides respectively of the upper post. The two flanges 7c extend a suitable distance longitudinally of the joists or beams D in Figs. 1 and 2 and overlap opposite sides respectively of the said joists or beams. The flanges of the upper plate and the flanges of the lower plate are parallel.

The flanges of the lower plate G are braced apart by angle-plates L which extend between and are arranged at a right angle to the said flanges at opposite sides respectively of the lower post A. Each angle-plate L is arranged with one of its wings abutting against the adjacent side of the lower post A and NIT/l1 its other wing abutting against the under side of the plate G. The last-men tioned wing of the angle-plate is riveted to the plates G and K, as at R. That is, suitably applied rivets R secure the two plates G and K and the angle-plates L together.

It will be observed, therefore, that my improved construction comprises the following :an upper flanged plate K arranged in a horizontal plane and under and next the lower end of the upper post B and extending under and longitudinally of the joists or beams, said plate having two laterally spaced upwardly projecting flanges 7c extending longitudinally and from end to end of the plate and overlapping opposite sides respectively of the joists or beams; a lower flanged plate G arranged next below and parallel with the upper plate, said lower plate extending longitudinally of and aflording bearing to the upper plate from end to end of the up per plate and having two laterally spaced downwardly projecting flanges g which extend longitudinally and from end to end of the respective plate; two angle-plates L spaced longitudinally of and arranged next under the lower plate G and extending between and contiguous to the flanges g of the lower plate, and rivets R extending through thetwo superimposed parallel plates G and K and through the angle-plates L and instrumental in securing the said plates G, K and L together. It will also be observed that the said angle-plates have their downwardly pro jecting wings or members arranged to abut or bear laterally against the lower post A upon mounting the post-cap on the said post as shown in Fig. 1, so as to prevent displacement of the post-cap endwise of the plates G and K and consequently longitudinally of the joists or beams; that the said angle-plates have their other laterally projecting wings or members arranged next below the plate G and secured to both plates G and K by the rivets R, and that the said angle-plates are instrumental in reinforcing opposite endportions respectively of the said plates G and i. It will also be observed that the post cap hereinbefore described requires the assemblage of only two flanged plates G and K and two angle-plates. The component parts can be inexpensively carried in stock, and convenient selection made from the stock to meet the dimensions or requirements of diflerent sizes and shapes of post-cap The two flanged plates G and K correspond in length in all sizes and shapes of post-caps, so that the lower plate G affords a bottom bean ing to the upper plate K from end to end of the plates. If the upper post B were thicker widthwise of the post-cap than shown in Fig. 2, an upper plate K wider than illustrated in this figure would of course be employed in lieu of the plate K shown. Similarly, if the lower post A were not as thick widthwise of the post-cap as illustrated in Fig. 2, a lower plate G narrower than the plate G illustrated would be used and shorter angleplates L employed. Also in my improved construction of post-cap the two flanged plates G and K and the angle-plates L are secured to gether by the same rivets It so as to keep the cost of construction down to a minimum.
