RALPH I-I. BROWN, OF WORCESTER, MASSACHUSETTS.
To all whom it may concer/n.;
Be it known that I, RALPH H. BROWN, a citizen of the United States, residing at lVorcester, in the co-unty of lVorcester and State of Massachusetts, have invented a new and useful Socket-Joint, of which the following is a speciiication.
This invention is particularlydesigned for use with cement filled columns, although capable of use successfully with pipe, solid, or other columns.
The principal objects of the invention are to provide a construction for supporting the beams in such a way that the beams shall apply a direct thrust to the socket joint itself instead of exerting a shearing strain upon the supporting platform, whereby the bending action on the platform is eliminated or decreased and the utility of the device is greatly increased, and whereby for the same load a socket piece of much lighter construction canv be employed; also to provide a construction for this purpose which shall be as near continuous as possible at the joint; in which no holes for bolster screws will be required in the body of the column; and in which no screw threads have to be cut in the column as for a iange joint; to provide a construction in which the column suers no loss of transverse strength at the joint, and in which the joint can readily be inspected at the building and the size of all its parts measured before its erection.
Further objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings in which- Figure 1 is a plan of a socket joint and beam connection constructed in accordance with this invention; and Fig. 2 is a central transverse sectional view thereof.
The invention is shown as applied to connect the lower column a and upper column for the purpose of supporting horizontal beams e. The socket joint is shown as comprising a cylindrical portion D having a diaphragm CZ extending across the same, which may be perforated or not at (Z2 as desired. This diaphragm is part-way between the top and bottom and obviously the cylindrical body with the diaphragm affords two concentric sockets, one at the bottom for receiving the top of the lower column a, and the other at the top for receiving the bottom of the upper column o. Integrally connected with the cylindrical shell is a Specicaton of Letters Patent.

series of triangular supporting webs cl3 having their apexes at the bottom and widened out at the top. These webs support the outer edges of a horizontal platform Clt which like the webs is integral with the socket and which extends outwardly from the top thereof and is flush with the top.. This platform as will' be seen, extends clear in to the surface of the upper column o. In order to eliminate bending action on the platform or socket, in case the beam should be out of line, the platform may be curved downward at the outer edge as shown at d5. The beams may be bolted to the platform by bolts e if desired. Where special rigidity is required as in a joint with an eccentric load, a cement grouting f can be introduced into theupper socket. From this construction it will be seen that the platform affords a firm and rigid support for the beams, and that any desired number of beams can be supported upon it, either when it projects in only one or more directions from the center or when it is symmetrical around the column.
The principal feature is that the beams project substantially into contact with the upper column, so that their ends rest directly overrthe vertical wall of the cylindrical joint. Consequently there is no shearing strain exerted by the beams on the platform itself. This is an advantage over such prior constructions as I am acquainted with for the reason that they require a vertical wall outside the upper column above the platform, and this wall prevents the beam being rested directly over the Vmaterial of the cylindrical portion of the joint, and
consequently necessitates the resting of the end of the beam on the platform beyond the circumference of this cylindrical portion. This in the ordinary forms of beams exerts a shearing and bending strain o-n the platform which must be resisted by much more metal than is the case with a direct thrust as is the case with my invention. It will be seen therefore that this result is secured by having the entire socket located below the platform and having it provided with a socket for the upper column also located below the platform.
It will be seen that all the holes necessary for bolts or screws, are made in the platform and none need be made in the body of the column. Thus a material source of weakness is completely avoided and another one is avoided by reason of the fact that no screw threads are to be cut on the column for the flange joint. This socket is preferable to a connection made with flanges and pintles as the column suffers no loss of strength at the joint. Another advantage is that the joint can be inspected very readily at t-he building and the size of all its parts measured before it is erected, as no part of it is built into the column during construction. The end of the frame also can be brought up against the column.
Although I have illustrated and described a preferred form of the invention, I am aware that many modifications can be made in the same by any person skilled in the art without departing from the scope of the invention as expressed in the claim. Therefore I do not wish to be limited to the details of construction herein shown and described, but
That I do claim is The combination with a lower Column, of a socket piece having aA cylindrical body provided with a concentric downwardly opening socket fitting' the top of said column, a diaphragm about mid Yay between the top and bottom of the socket piece resting on the top of said column, and an up wardly opening cylindrical socket of substantially the same size as the lower socket, whereby it has cylindrical vertical wallsI bounding both sockets and integral with the diaphragm, said walls extending from the bottom of the socket piece materially above the diaphragm in the form of a uniform hollow cylinder, said socket piece being provided with a horizontal platform flush with its top and integral therewith, triangular webs extending from a point just below the diaphragm up to the platform and integral with bot-h and having their widest dimension at the top, an upper column projecting about half way to the bottom of the socket piece and resting on said diaphragm, and beams resting on the top of said platform entirely above the socket piece and having their ends substantially in Contact with the upper column and directly over the entire thickness of the vertical walls of the socket piece.
In testimony whereof I have hereunto set my hand, in the presence of two subseribingwitnesses.
