" all whom it may concern:

Be it known that SIMON it. BRYAN. of Racine, in the county of Racine, in the State oi 'v'i'isconsin, have invented new and useful Improvements in Railway- Rail Stays, of

Specification of Reissued Letters Patent.

which the following, taken in connection with the aoc-onipanying drawings, is a full, clear. and exact description.

This invention relates to the class oi. rail .Reissued'Oct. is; less.

. of the drawings. The bottom of one of the :55

extensions 0 is provided with a transverse groovof, and the bottom of the other oi said extensions is formed with a tongue if, which passes through the groove f when the jafivs are applied to the rail.

groove connection serves to maintain the stays or anchors which are designed to prc Vent longitudinal creeping of the rails of railmeans oi a vertical plate iz'ft'orined on-the end.

roads; and the invention consists in a novel construction and combination of its coinponent parts which cause the rail-stay to automatically tighten its hold on the rail by the strain exerted in resisting the creeping of the rails; and the invention also embodies certain novel features of its details, as hereinafter described, and summed up in the claims.

Inthe accompanying drawings, l igui'e 1 is a transverse section of a rail equipped with my invention. Fig. 2 is a side view of the same. Fig. 3 is an inverted plan view of my improved rail-stay. plan view of the arm which, in the specific embodiment of my invention shownin the drawings, serves to engage av relatively s1 a tionaryabutment, such as av sleeper or tie. to enable the entire device to resist the creeping strain of the rail and also serves as a means for tightening the jaws upon the rail. Fig. 5 is a plan view of the rail-gripping jaws, and Figs. 6 and 7 are. inverted inner end views of the said jaws.

Similar letters of reference indicate corresponding parts.

R denotes the railway-rail, and A the cross-tie, which supports said rail in the usual manner.

The arrow in Fig. 2 indicates the direction in which the rail tends to creep.

(l a are-the rail-gripping members of the rail-stay, which members are preferably of the form of hooks or jaws, which are disposed ,to engage the flanges b b on op )ositc sides of the rail, and thus grip the rail between the jaws. Said jaws are formed with downwardly and inwardly inclined extensions c. terminating in horizontal wedge flanges (I (I. which are beveled toward each other and. are disposed lengthwise under the rail Pt and formed with longitudinal grooves c under the Fig. 4 is an invcricd jaws in line with each other.

9 represents a horizontal arm which is dis-- posed lengthwiseunder the'iiail .ilan'd 1S rigidly sustained against the cross-tie A llji fi of the said arm and-abutting the side) oi the cross-tie. The said arm is girovi ed" with suitable means for conipi the wo wedge flanges d a, and thus ti htening tlie'ic' grip of the aws (i (1 on the rail it. lore'iere- T ably form said arm with ribs or w i i, which are inclined endwise toward each other, corresponding to the bends of the two i wedge flanges d (I, and receive said wedges '75 betweentl'iem, as shown in Figl lot the Q drawings, the inclination ol the i i i be'. ing illustrated in Fig; 411i the drawings. The said ways are undercut longitiidii-ialiy,

as shown at 1. to receive. the adjacent wedge-s r1 (1, and thus couple the arm 9 to the jaws at].

in the operation of the described rail-stay the longitudinal strain exerted on the rail due to its tendency to creep longitudinallyT causes the wedge Ha; s 7 (I of the jaws (I (1 to be l'orccd tightly toward the coi veigi g ends if Th0 ways i i. and thus drawsa'id wedges together, thereby drawing the jaws (I (I more tightly against the hinges oi the rail. Hence niy improved railstay adjusted automatically to securely gripthe rail, and thus its efficiency is materially in-Z creased and it is rendered sate and reliable.

It will be observed that in its essential features my invention comprises the jaws-'95 rail, whereby a relative niovmient of the loo connecting parts toward each other length wise of the rail will cause the jaws'to'bea drawn toward each other and to more: tightly grip the rail. [n the embodiment of my invention shown in the drawings-the connecting parts comprise the xtensions c and the horizontal arm g. hut it is immaterial outer edge's of the wedges, :LS'HllOVVll in Fig.1 2 how manyindividual nart-s may be used to Said tonguegandparts, be they few or many, which connect the jaws with each other are rovided with. these co-engaging shoulders w ereby a rela tive movement of one or more of the connecting parts lengthwise of the rail will cause the-wedge-shaped shoulders to cooperate to draw the rail gripping aws more ti htly together. The essence of this feature 0 m invention is the use of such co-engaging s oulders u on that part or those parts of the device whic extend beneath the rail and connect the jaws to each other.
