To all whom atmagy concern. 8

Be it known that I, LOUIS PLnsHn, a citizen of the United States, residing at- Chicago, in the county of Cook and State of Illinois, have invented new and useful improvements in RailJoints, of which the following is a specification.

This invention relates to railway rail joints and an object of, the invention is'to provide'a joint for railwayrails which will prevent the sinking of the meeting ends of the rails, prevent lateral spreadingmove ment and one which is designed to bring pressure to bear upon the rails, laterally and vertically in both up and down directions upon the base of the rails to securely and firmly hold the rails against any relatire movement.

Other objects of the invention will appear in the following detailed description and in the accompanying drawings wherein:

Figure 1 is a top plan of the improved rail oint.

Fig. 2 is a perspective view of the rail joint.

Fig. 3 is a perspective view of the rail joint showing the side opposite to that illustrated in Fig. 2.

Fig. 4 is a cross section through the rail joint taken on the line l-d of Fig. 1.

Fig. 5 is a detailed perspective of one of the c amping plates of the rail joint.

Fig. 6 is a detailed perspective of the other clamping plate of the rail joint.

Fig. 7 is a detailed side elevation of a clamping washer used in the rail joint.

Referring more particularly to the drawings, the. improved rail clamp comprises clampingplates l and 2, one of which is positioned upon each side of the webs 3 of ordinary T rails 4 at their meeting ends. as clearly shown in Fig. 1 of the drawing. These clamping plates 1 and 2 are provided with upwardly facing slightly inclined upper edges 5 which engage against the under surface of the heads 6 of the rails t'while their base flanges 7 are shaped to snugly abut the upper surfaces of the bases 8 of the rails 4. Clamping plates 1 and 2 are securelyclamped in engagement with the rails 4 by bolts 9 which extend transversely through the webs 3 of the rails and through the clamping plates 1 and 2. As the nuts 10 are tightened upon the threaded ends of the bolts 9, the clamping plates 1 and 2 will be drawn toward each other and conse- Specification of Letters latent.

quently toward the webs '3 of the rails, thereby applyingclamping pressure against the undersurface. of the ball or head 6 of the rails and against theupper surfaces of the bases 8 also applying lateral pressure to the rails the platesand are engaged. v

The clamping plate 1 has a hook shaped extensionll formed thereon intermediate owing to the inclined surfaces of port ons of the rails which" its ends which extension or rib 11 has its lower end formed integral-1y with the hook shaped extension 12 formed along a portion f the'outer edge ofthe base 7 of the clamp ing plate 1. The extension 12 has its free edge curved upwardly as clearly shown in Figs. 4: and 6 of the drawing for receiving therein the rounded free end or ball 13 of a clamping pawl 14. The clamping pawl 14 has its upper surface convexly curved for engagement against the under surface of.

the bases 8 of the rails 4: at their meeting ends and a bolt 15 is connected to the pawl 1 1 and extends upwardly between spaced ribs 16 and 17 formed on the outer end of an extension 18. The extension 18 is formed upon the clamping plate 2 and its base 7 is enlarged laterally as shown at 19 intermediate its ends to provide reinforcement for the ribs 16 and 17. The bolt'15 also extends through a clamping washer 20 provided with a a bolt receiving opening 21 and with depending tongues 22 and 23, one upon each end, which tongues engage over the outer surfaces of the ribs 16 and 17 to hold the washer 20 in place. lVhen the nut 24L, mounted on the upper threaded end of the bolt 15 and in engagement with the upper surface of the washer 20, istightened upon the bolt 15 the pawl 14 will rock upon its point f engagement with the bases 8 of the rails 1, forcing the rounded end 13 clownwardly and the bolt carrying end upwardly until the limit of its pivotal movement is reached owing to failure of yielding move ment of the hook shaped extension 12, after which further tightening action of the nut 24 will securely clamp the pawl let in en gagement with the bases 8applying pressure to the bases from below and also apply ing pressure to the bases from above owing to the engagement between the rounded end 13 and extension 12 and the pressure of the bolt 15 and nut 24 upon the ribs 16 and 17.

it is, of course, to be understood that the invention may be constructed in various the head of a T rail, a hook extension on other manners and the parts associated in different relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus descrlbed my lnventlonwhat I claim is v 1. Ina rail joint, the combination, of rail said pawl to adjust the pawl for applying clamping pressure to rails.

j 2. In a rail joint, the combination, of rail clamping plates having their upper edges shaped to snugly fit the undersurfaces of one of said plates, a clampingpawl, adjustpawl provided withIa convex surface adapting' means carried by the other 7 of said clamping plates and connectedv to said clamping pawl for adjusting the clamping pawl for applying pressuret toa rail, said ed for engagement withthe under surface of a rail base. 7 I I V 8. In a rail joint, rail clamping plates having their upper edges shaped for snug fit against the under surface of a rail head, a hook extension on one of said plates, a clamping pawl having one endrounded for engaging 1n said hook extension, laterally extending ribs formed upon the other of said clamping plates, a bolt, extending be tween said ribs and connected to said pawl, a clamping washer on said bolt, a nut on said bolt for drawing said clamping pawl into clamping engagement with a rail and I said hook extension.

4:. A rail j oint: comprising clamping plates, a pawl rocking upon the base of the rails'andhaving a pivotal connection withoneplate and an adjustable connection with the other plate. 7 I 2 In testimony whereof I afiix l ly-signature,
