JOINT Foa FLANGED sEAMs.l

SPECIFICATION forming part of Letters Patent No. 711,699, dated October 21, 1902.

Application filed August 2, 1902. 4

l' of an improved joint for flanged metallic beams, including railroad track rails, I- beams,channelbeams,Z-bearns, bulb=beams, dto., which can be easily and quickly formed, which shall be cheap in iirst cost,'which shall be very strong and durable, which shall admit of facile manipulation in uniting and separating the parts, and which withal shall constitute a superior means for connecting the adjacent ends of metallic or other flanged beams.

My invention consists in certain novelties of construction and combinations of parts hereinafter set forth and claimed.4

The accompanying drawings illustrate three examples of the physical embodiment of my invention constructed according to the best modes I have so far devised for the practical application of the principle.

Figure 1 is a perspective view of the ends of railroad-track rails united by my improved joint. Fig. 3 is a section on line acm. Fig. 2 is a section on line y y. Fig. t is a perspective View of the ends of two I-beams fashioned to form a joint and with the ends separated. Fig. 5 is a view similar to Fig. 4., showing my invention in connection with channel-beams.

Referring to the several figures, the letter A designates the upper head or liange of a beam; B, the lower ange; C, the web; D, a tailpiece formed by removing portions of the upper head or iiange and lowerilange; E, the relatively long free edge of th'e 'tailpiece; F, the relatively short free edge ofthe tailpiece; G, an offset or knuckle; H, a clamp; I, the

bolt-piece of the clamp; J, the threaded boltv end; K, the bent end. fashioned to frictionally fit the flange; L, the perpendicular bearing end; M, the nut-piece of the clamp; N, the perpendicular bearing end; O, the curved end; P, the extreme end of the curved portion, frictionally engaging the surface of the Serial No. 118,077. (No model.)

bolt end of the clamp upon its lower surface; Q, holes for bolts in the tailpiece and web, and R designates the line upon which the web is separated from the lower flange when so desired to allow the tailpiece to be oset to a plane parallel with the yplane ofthe permanent web of the rail or beam.

It will be observed that when the ends of the rails or beams are brought together the sectional surfaces'of the heads or iianges are in frictional contact and thatvthe tailpiece of one rail or beam laps over the end of the other rail or beam, and thus forms at the points where the heads or lianges are cut away a web of double-thicknessor two webs.

From the foregoing specific description,

Ataken in connection with the drawings, it is obvious that Ihave produced a joint for flanged beams which fulfils all the conditions set forth as the object of my invention.

While I have shown only three Aexamples of the physical embodiment of my invention, I do not therebyintend to limit the scope thereof to such examples, inasmuch as moditications may be introduced in practice without constituting substantial departures.

/Vhat I claim as new, and desire to secure by Letters Patent, is- I l. A joint for iianged beams comprising the ends of two beamsof similar structure, each end of a beam having an offset tailpiece with a relatively long free edge and a relatively short free edge, the headsor ianges of both beams being inV contact and the tailpiece of each beam overlapping the end of the other beam, and means for holding the ends of the beams in place.

' 2. A joint for flanged beams comprising the ends of two beamsof similar structure, each end ofia beam having an offsettailpiecawhich overlaps the end of the other beam, the fianges of the ends of the two beamsbeing located in line and'one matching theother, and` means wfor holding the ends of the bearnsftogether;

the points of union of theilanges at thetop of the joint being in a different perpendicular plane from the point of union of the iianges at the bottom of the joint. e

3. A joint for railroad-track rails comprising the adjacent ends of two rails, each rail having an oset tailpiece which overlaps the IOO end of the adjacent rail, the heads and bottom iianges of said rails being in line and matching and with the respective points of union in diiferent perpendicular planes, and means for holding the ends of the rails in alinement.

4. The combination with jointed flanged beams in which a tailpiece of each beam overlaps the end of the other beam, of a clamp comprising a bolt-piece and a nut-piece, each of said pieces having a bearing end which respectively engages the web and tailpieoe of the jointed beams, and a nut for engaging the threaded end of the bolt-piece.

5. Aolamp comprisingaboltpiece,l,having a bent end, K, and bearing end, L, and a perforated nut-piece, M, having a top bearing portion, N, and a curved portion with an end, O, which frietionally bears against the bolt portion, and a nut for engaging the threaded end of the bolt-piece.

6. The combination in forming a joint, of a flanged beam having an offset tailpieoe With free edges of unequal lengths; a flan ged beam having an oiset tailpieee separated from the lower iange on the line, R; and means for holding the ends together when joined.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN ELLMORE.
