5 Claims. (Cl. 18S-36) My invention relates to skeleton metallic structures such as are used for building and the like, at Il-I'IV an and has for its object the provision of means Darts together I am able to increase the shearing whereby such a structure may be more readily I will explain my invention more in detail by referring to the accompanying drawing illus- Fig. 1 is a fragmentary perspective view illustrating one form which my invention may take; Fig. 2 is a sectional view along line 2 of Fig. 1,' Fig. 3 is a sectional view along line 3-3 of Fig. 4 is an enlarged side View of a detail feature of one form of the invention as shown in Fig. l;

skeleton framework of a building, which fragmentary illustration is thought to be all that is needed to illustrate the same. In this figure I show one of the columns l0 of a building which Il, which girders in turn support beams I2-|2. I have also shown the column l0 as supporting a beam I3.
My invention contemplates that the girder Il plate has converging sides which are adapted to seat in a supporting socket I5 welded to the column l and having correspondingly sloping pockets to rreceive the plate or tongue I4.
buildings the girders are attached to the columns by means of angles riveted both to the girder web and to the column. In general, rivets are used which are placed about three inches apart stress of about five thousand pounds, so that throughout the length of the riveted area the resistance to shear is about twenty-five hundred pounds per inch.
5 In the construction which I propose, the plate stand a sheari per inch if lle Similarly I shown at I8, or I may rivet it al and above the ri girder, for insta with the upper surfac intention, or should it be desired uch as that outlined may withng stress of six thousand pounds t welded on both sides as is shown.
with their necessary of my invention. If the beams I2 faces I9 aligned are not to have their upper sur- 14 is niiet welded to the girder webis as 'shown Vlustrated and described heretofore.
per surfaces of girder and beam aligned, then I utilize the structure shown in Figs. 4, 5 and 6.
Fig. 4 shows a structure which I utilize at one extremity of the girder and Figs. 5 and 6 show the structure which I utilizeA at the other extremity of the girder. Sometimes it is necessary to duplicate the structure of Figs. 5 and 6 at both-extremities. The structure for one end of the beam as shown in Fig. 4 consists in cutting away as shown at 2l a portion of the beam and providing the extremity of the beam with a plate I4. This plate cooperates with a socket I5 such as il- It will be seen that if the beam of Fig. 4 were raised a certain amount, that the tongue or plate I4 would be clear of the socket I5 because of the converging nature of the sides of the elements I4 and I5. It will be at once apparent, however, that under these conditions there would be interference if the opposite end of the beam had similar means for mounting inplace. In order to avoid such interference, I utilize the form of union as shown in Figs. 5 and 6 in which one side of the web of a beam is provided with a longitudinally extending socket 22` in which an angle plate 23 is slidably mounted, this plate having the outstanding leg 24. The cpposite'side of the web may have the nonadjustable angle 3ll with its outstanding leg 3l. These plates 23 remain in the position shown in Figs.5 and 6 while swinging the beam into position to alignthe plate` I4 with the socket I5. Thereupon the sliding plate 23 is moved outwardly until the tongue 2lik registers with corresponding socket I5 in` V the other gir-der, whereupon the beam may be dropped into position. The sockets 22 are of course suitably welded to the web as shown at 25. In this manner there will be no interference between the beam ends and the girders between which the beam is to be mounted.
In Fig 7, Ihave shown the assembling feature of my invention as applied to a structure in which rivets may be employed, if so desired. In this particular case I construct the socket portion 26 as shownV so thatrit` may be riveted to the column to properly receive the tongues 21-21 forming parts of angles riveted to the web IG of the girder The socket section 2E likewise may be riveted to the column if so desired, although as readily apparent this structure of Fig. 7 lends itself equally well to fillet welding.
From what has thus been described, it is thought the nature of my invention is readily apparent to those skilledrin the art.
Having thus described what seems to me at the present time to be the approved forms without intending to limit myself thereto, I claim the following:
1. In a metallic skeleton framework for buildings and the like, means for connecting the end of an I-beam to a supporting member of the framework comprising a pair of plates one having tapered opposed grooves on one face thereof, and the other having its side edges tapered to seat in said grooves, one of said plates being xed to the web of said I-beam and extending transversely thereto, the other of said plates beingxed on said member.
2. In a metallic skeleton framework, means for `making a web to web joint between two beams having top and bottom flanges comprising a plate member providing a socket o-n the web or one beam, a vertical mounting plate on the end of the web of the other beam, .said plate being insertible between the socket and top flange by horizontal movement of one beam relative to the other.
3. In a metallic skeleton frameworkmeans for making a web to web joint between two beams having top and bottom flanges comprising a plate member providing a socket on Vthe web of one beam, a vertical mounting plate on the endof the webV of the other beam, said mounting plate being divided into two sections along the web,
one section being movable lengthwise of the web.
4. In a metallic skeleton framework, means for attachingrthe end of a beam "havingtop and bottom flanges connected bya web to a supporting member which comprises a pair of plates having interiitting side edge portions, one of said plates being fixed on the supporting member, the other plate being fixed to the end o i the web of the beam andextending outwardly from both sides of the web to provide side bracing for said beam.
5. In a metallic skeleton framework, means for attaching the end of a beam having top and bottom flanges. connected by a web to a supporting member which comprises Aa pair ofplates having interfitting side edge portions, one of said plates being fixed on the supporting member, the other plate being fixed to the end of the web of the beam and extending outwardly from both sides of the web to provi-de side bracing for said beam, said web and the plate thereon by llet welding.
