improve the device illustrated in my United 15 States patent application, Serial Noa'lzl lfill,

allowed March 26, 1914:.

In the drawings accompanying this speci fication there is illustrated a simple but set isfactory reduction of my improvement to 20 practice. i

in the said drawings: Figure 1 is a side elevation showing the-device applied to a rail joint,Fig. 2 is an enlarged sectional View taken approximately on. the line 2-2 Fig. 1, Fig. 3 is a detail perspective view out the protector, plates or liners Fig. t is a transverse sectional view through a rail illustrating a modification, Fig. 5 is a per.- spective view of the protector plates em- 39 ployed in the device illustrated in Fig. i; and Fig. 6 is a top plan view of two rails showing the improvement illustrated in Figs. e and 5 arranged thereon.

in my pending, application lilo. 7%,811 ll 3 employ sprin chimps, each of which have both an upper and. a lower jaw secured to the rails by a bolt having a hook and which cngiagrs with the longitudinal edge of the base flange of the rails opposite that en- Y gagged by the ju'WS of the clamp. I also arrange between the jaws a bond or connecting; Wire which is forced by the clamps against the longitudinal, edges of the base flanges of the rails.

4:5 I have found that in a number of instances it is desire-dc to employ in connection wih the clamps and conductor Wire a liner in the nature ot a plate which is arranged hcltween the jaws of the clamp and which is no of highly electric conducting material.

Serial No. 853,181.

3 is provided with an opening thr iiug-jh which passes the threzuled end of' av bolt 6, a nut '4' being employed to secure the bolt upon the clamp, while the opposite end oi the said bolt is ll'oohed, asat 8, and engages with the longitudinal edge of the rail opposite that engaged by the clamp.

llhe numerals 9 designate the liners for each of the clamps. Each of the liners is of a length approximately equaling the width of the clamps and each of the said. liners includes a flat base 16, a curved portion 11 which corresgonds with the all. provided by the aperture 2 and a top plate 12 which is preferably of a less width than the base 10. The rounded portion 11 is compressed against the conductor 1 by the clamps 5 while the top and bottom 12 and 10 respectively are forced against the upper and lower faces of the base portion of the rails when the nut 7 is screwed home upon the bolt 6. y

In Figs. t and 6 the clamp 12 is provided with a rail engaging jaw M and a base portion 15 which is arranged at an angle to the jawancl which is adapted to be received heneath the baseof the. rails. ihlfiolt 16 passes through an opening" in the hails 15 and is secured thereon by anut 17, While the opposite end of the bolt is hooked, as at 18, and

engages with the opposite longitudinal edges of the rails. The liners or conductor protectors :21 are of a width approximately equaling; the width of the clamps 13 and are formed each from. a sheet of copper or 1 1 other suitable conducting; material. Each of the liners includes a lower l lat base portion 24, an angular top portion and the said top has its edge rolled to provide a housing 19 for the conductor wire 20. The free edge of the round housing! is soldered to the top 22, as indicated by the. numeral 25 and the conductor wire 20 may he also soldered in the housing.

It will be noted that the opposite faces of the liner are engaged by the opposite jaws of the clamp and also that the pointed edge f the upper jaw let of each of the clamps is forced against the end wall of the hous ing and as a consequence has a tendency to compress the housing against the conductor.

From the above description, taken in con-' nection with the accompanying drawings. the simplicity of the device as well as the advantages thereof will, it is thought he peru fect-ly e 3 e re nt to I eleim. 1s:
