T all whom t ma concern: l, i

Be it known t at we, JoH'nR. BOWERS,

Jon-NA A. Poma, and Comi. B'. DARN'nLn,

citizens of the United States, residing at Newburg, in the county of Phelps, State of Missouri, have invented a new and useful.

and lin the details of construction `hereinater described and claimed, it being under-l ment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spiritl of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure l is a side elevation of the improved joint or chair. Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is an enlarged transverse section taken on the line 3 3 of Fig. 2.

In carrying out the invention, reference being had in detail to the drawing, there is provided a rail chair embodying a base or bottom 1 having the integral angle iron sides or fish plates 2, in order that the chair may be adapted to receive the meeting ends of the rails with the sh plates `2 engaging under the treads or balls of the rails. The base iianges of the rail ends are adapted to seat upon the base or bottoni of the rail chair under the fish plates-2, as will be apparent.

stood that changes in the precise embodi-l In order t'o clamp the iish plates tightly' against the rail ends when the pressure is spe-amavano: tener; 11mm. .Patented Nov, 24, 1914 Application ed June 0, 1918. Serial No. 774,889.

. the' central portion of the base or bottom i will be depressed, and consequently, the fisl plates `will be firmly clam ed against th rail ends to hold them tiglitly in positie; while the train is traversing the rail end: Ordinarily, the ish plates 2 will be expand edl slightly, to relieve the chair, as well a the rail ends, of .any undue strain, excep when the rail ends are weighted down by locomotive-or train.

In order-to spike or secure the 1chair t the ties, the lower flan es 5 of the fishplate are provided with spte openings 6, whic] aline with similar openings 7 in the base o bottoms-1 of the chair.` The s ikes 8 ar adapted to be .driven through e openin 6 and 7 into the underlying tie or ties 9, t spike openings at-the respective sides bein,I in staggered relation with respect to on another, and the base flanges of the rails be ing. provided with clon ated openings 1 through which the spies ass, thereb; maintaining the rail ends wit in the chai] but permitting them to expand and contrae due to atmospheric conditions. The rai chair is thus effectively spiked to the tief together with the rail ends.

In order to electrically connect the rai ends for purpose of block signaling, or fo purpose 'of forming the leg of an electrica circuit7 the upright flanges of the fish plate are provided with the complementary lon itudinal slots or openings 11 intermedia-t t cir ends, and adjoining the meeting end of the rails. A coiled wire or elasticrai bond 12 is disposed or housed within one o the slots or' openings 11 and has its ends 1 engaged through apertures provided in th webs of the rail ends intermediate the end of the slots 11, and bent within the othe slot 11. The bond is thus housed within th rail clir, and may be readily and inex pensively applied to the rails to provide a: eiiicient electrical connection or bond fo the rails. The ends of the rail bond bein,` engaged through the webs of the rail a speciiied also provide an important functior in that, should the rails separate excessively the ends of the bond will be sheared by th ends of the slots, so as to break, or open th electrical circuit, thus interrupting the bloc signal system to indicate danger, In thi manner, accidents may be avoided, due t the excessive separation of the rails, whicl otherwise could not be guarded against. After the defect is remedied= a new bond ma y he easily applied to reestablish the electrical circuit. eliminates the use of bolts or other securing members for clamping the ish plates to the rails, which is a desirable feature, in that, it not only reduces the cost of the joint, but permits the rails to be readily. attached or connected, especially when repairs are necessary. The present rail joint or chair may be employed for use in steam railroads, and inter-urban and city street car' lines, the ordinary rail bonds being replaced by the rail bonds as above described. The present rail bond cannot be torn loose or injured by any obstacle that may be dragged or carried by the locomotive 'or cars, the rail bond being effectively housed within the chair.

Other advantages ofl the present device will be apparent tothose versed in the art, it being noted that the objects aimed at have been carried outsatisfactorily, and that the present device provides a desirable one for the purposes for which' it is designed. The lower flange of the fish plates may be rovided with longitudinal grooves 14 a ong The joint. as thus provided the edges of the base to permitthe sh plates to yield relative to the baseL if necessary.

Having described the invention, what is claimed as new is In combination, a rail chair having sides and the sides having complementary slots, rails'liaving their ends received by the chair between the sides thereof, the rail Webs having apertures therethrough intermediate the ends of the said slots, and an elastic rail bond housed Within one of said slots and having its terminal portions lengaged through the said apertures and bent within the other slot, the ends of the said slotsv being arranged to shear the terminal portions of the bond should the rails separate excessively.

In testimony that We cla-im the foregoing as our own, We have hereto afiixed our` signatures in the presence of two witnesses.
