THE NORRIS PETERS Cl l. PHOTQ-LITHQ, WAJIHINGTUN L)v F BONNIE L. Marianna cnisvnnnNn, oHIo.

ToiaZZ, whom it may 50mm 'Beit known that I, BONNIE L. MAL-Loaf,

a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and Stat-eof Ohio,fhave invented a new anduseful Improvement in Joints for Longitudinal Members, of which the following is a full,

clear, and exact description, reference being.

had to the accompanying drawings.

This invention relates tojoints between the ends of longitudinal members, such as railway rails, I-beams and the like, and, generally speaking, it has for its object the simplification: and cheapening ofjoints of this character without; by. :so doing, destroying their efliciency; Many of these joints have been devised that would be quite strong and noiseless'if they could be produced comm'er-' 1 cially, but'tliey-have been so shaped that the excessive cost of their manufacture has made their use impracticable. In my presentform of joint Ihave retained most 'ofthe advan tages of these complex forms, and have so rydesigned fit that it can be produced with sufficient economy as to make practical its GXtBIlSlVGllSG. Moreover, I- have adapted it foruse 1n railway constructions having elec tricsignaling systems, all as will more tclearly appear from the followingspecifica tion describing the joint. shown'iin the companying drawings, in which V Figures 1 and 2 are perspective views of the adjacent ends of a pair of railwayrails'that ihavebeen shaped in the manner for forming my. improved joint; Fig; 3 is "a :plan view,

partly in section, showing parts of the rails of'the foregoing figures joined; Fig. 4 is a side elevation of the ends of the joined Lrails; Figs. 5 land 6 are transverse sections 40 taken on lines 55 and 6+6, respectively of Fig. 4; Fig. 7 is a sectional View like that of Fig. 6 except that it showsthe insulation that 'may be used inthe joint when desired .Efor use .in an electric signaling system, Figs. 8 and' '9 areperspectlve views of the prepared pieces of insulation for use in my joint, and Fig. 10 is a perspective viewfof my joint as applied to an I-beam.

;I 'F'rst taking up a descriptionof the rail- 50 way-rail joint, shownin-Figs. l to 6, A and B represent therespective adjacent ends of tworailway rails, the same having the usual base and wheel flanges and the connecting webs. Projecting longitudinally from the ends of these rails are webmembers A and B respectively. These web members are identicallyalike, onewbeing formed at each JOINT FOR LoNGI'rUn N L MEMBERSQ end of each railbut on opposite sides of the median line of the railso that, in the completed joint, they formcomplements of each other, as will hereinafter appear. These members are each provided withbase flanges, shown at A and B the same being continuations, of the base flanges of the rail proper.; The upper v parts of the wheel. flanges of the rails are omitted fromthe web=extensions for a space adjacent the ends x Specification o f Letters Patent.

9f he'rails," as shown at A a d-Be tiyely, beyond. which spaces the full thick ness .ofxthe' flanges 'is again supplied, as

shown at A"=, B In the assembled joint,-

thewheel, flange sections Atand B are contained within the spaces B and A respectively, the parts beingheld together. by bolts 1 C-that are'passed through holes G in the: webs of the rails and through registering holes. 6 in lugs A andB -lthat project longitudinally tromthe free ends of the web 1 inembers'A and B".:-.Theholes C and C are slightly elongated, as shown, to provide for possible 1 expansion and contraction of the rails with changes in temperature, while i the wheel-flange SGCtiOIlSf A and B are made slightlyshorterthan their containing spaces for the same purpose. By making the spaces A -B andthe flange sections thinner than the wheel flange 4 proper, abroad andjstrong base support is provided: for. said sections.

In orderlto holdtt-he bolts 0 from turning *,while screwing ontheirnuts, bosses A and B ars-formed on the web members, these bosses having extensions A B on opposite T sidesof the bolt hole 0' in position to engage with the sides of the boltheads. -The heads o fthose bolts that arenext the web membersare thus confined onthree sides as if'they were held in'a wrench and are thereby'prevent'ed from turning. For holding the other bolts C, a lugB is formed onthe web of the rail B to engage with one side ofthe bolt head, it being understood that a corresponding lug is formed on the rail A.

The wheel flange sections A and B, as

well as the spaces A and B are provided with beveled or transversely inclined ends, as shown, in order to facilitate assembling the rails and to deaden the noise, it being understood that, with this'construction, the wheels will-rest onboth-rails at thesame time and will not pass instantly" fromone rail to the otherwith the accompanying noise, and shock, as is common with the ordinary oint; .1

to separate the rails electrically, as is sometimes necessary electric signaling s stems. The plece shown in Fig." 9 is 1nten ed for use under the lugs Aiand B and trans versely between the rails at that part of the" joint. Thus the part D, with the edge flanges D and D insulates the lug 13 as appears from Fig. 7, the bolts 0 passing through the holes D For still further insulating the lug, the bolt is surrounded with a spool of blushing D1 of fiber or other suit able material. For insulating the joint transverselyof the rails, the part D is further provided with a flange D at each end ofwhich is a flange D, D? respectively, said flanges being so shaped as to fit the end ofthe rail proper about the web member, as will be clear/from a comparison of Fig. 9 with the end of the'rail proper in Fig. l.

The parts E and F, with theirattached flanges E and F, lie between the web members A and B, the flanges E and F being turned over to. separate the wheel flange sections=l3 and A respectively from the web members A and B. Short lips E and F are turned up at the adjacent ends of the flanges E and F to fill. the space between the wheel flange sections A and B.

In Fig. 10 I have shown my-improved joint, applied to I-beams. These beams are represented at G and H. The web member H with its lug H and to flangesection H correspond in shape an function to the arts B, B and B of the rail B shown in *ig. 4, While the top flange section Gt correspondsto the wheel flange section A*-. In the I-beam, the parts are preferably held Itogether by rivets R instead of by bolts, although the latter may be employed.v

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a joint for longitudinal members,

thecombination with-said members, of overlapping web members projecting from the adjacent ends of'the longitudinal members, and a top flange section projecting from each of the web members over the other Web member, each of the web .members and its respective top flange section terminating in a common plane that is disposed at an obtuse angle to the longitudinal axis of the first mentioned members, the ends of the longitudinal members being inclined in a plane parallel to the ends of the web members. .7 Y
