SPECIFICATION formingpart of Letters Paten'tgNo. 712,132, dated October 28, 1902- Appumion nea February 12,1902. serrano'. 93,677. (Nomade.)

To fallu/hom it may concern:

Be it known that I, GEORGE L. HALL, a citizen of the United States of America, residing in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Insulated Rail-Jointaof which the following is a specification, reference being -had therein to the'accompanying drawings.

My invention relates to joints between adjacent rails of a railway; and its objects are to provide a strong union for the rail ends and cheap means of insulating them from each In some cases it may be found that the railjoint described in my application for Letters Patent filed January 18, 1902, Serial No. 90,233, Series of 1900, is not adapted to the situation and that the joint should be provided with an angle-chair.` y

To these endsv my invention consists of a two-part fish-plate, in combination with an angle-chair, of means of insulating the two parts of the fish-plate from each other and of the angle-chair from one of the rail ends.

I hereinafter describe a rail-joint embodying the features of my improvements and then point outthe novel features in the claims, having reference to the accompanying drawings, in which similar figures ofreference indicate similar parts throughout the'various views, of which- Figure `1 is a plan view, partly in section, of a rail-joint'embodyingrnyinvention. Fig. 2 is a side elevation. Fig. 3 is an end View, partly in section, on the line 3 3 of Fig. 1. Fig. 4 is a plan view of a modified form ofthe joint. Fig. 5 is a perspective yview of the angle-chair. Fig. 6 is a perspective view of a modified form of the angle-chair.

1 1 are ends of two railway-rails to be joined.

2 and 3Kare respectively ,parts of a fishplate. Each of said parts 2 and 3` is provided with one or more lugs 4 osetting from the same. These lugs may be so arranged as to be spiked to ties or so as to be run into the earth, or some of them may be arranged to be spiked to ties and others to be run into the earth. Said parts 2 and 3 of said fish-plate are also provided with offsetting lugs 5, adapted to be united by one or more bolts, rivets, or other joining devices 6.

7 and 8 are respectively parts of another fish-plate.. Each of said parts7 and S is provided with offsetting lugs 9, adaptedjto be ,united by one Nrrnn STATESI yPATENT OFFICE. I

or more bolts, rivets, or other joining devices y 10. Of course it will be understood that lugs 4 may in some cases be omitted from the par-ts 2 and 3 of the other fish-plate.

11, 11', and 11l designate the several parts of an anglechair, 11 being the part resting y upon the ties and adapted to be spiked thereto through holes 12, 11 being the upright part and provided with bolt-holes 13, and 11 being the supporting part of the chair. Said upright part 11" is formed of a fold or eXtra thicknessof the metal, so that it is substantially double the thickness of the parts 11 and 11. In this way the chair, and thereby the joint, is greatly strengthened.

v14 represents pieces ofpacking and insulating material, such as wood, between the upright part 11" of the angle-chair and the corresponding parts 7 and 8 of the two-part fish-plate on that side of the rail ends, said packing material being of sufficient thickness to prevent any electrical connection between j' the part 11H of the angle-chair and the lugs 9 of'fthe two-part fish-plate.

15 represents insulating material, preferably7 vegetable fiber, between lugs 5 5 of the parts 2 and 3 of one fish-plate and lugs 9 9 of the parts 7 and 8 of the other fish-plate, and extending between the rail ends 1 1though said insulation may be omitted between the rail ends if they are properly separated by airspace.

16 represents bolts passing through the up right part 11" of the angle-chair, the packing 14, the respective parts 7 and 8 of one fishplate, the rail ends 1, and the respective parts 2 and 3 of the other sh-plate.

17 represents thimbles or bushings of insu' IOO It will be readily understood that it is necessary only to insulate from the angle-chair one of the two rail ends, as shownY in Fig. l of the drawings.

22 represents insulating material intermediate of the bottom of the rail ends and supporting part 1l of the angle-chair. A good method of holding said insulating material in place is shown in Fig. 3. Said insulating material is provided at each end with a lap 25, adapted to be folded upon the upper surface of bottom flange of the rail ends, and the anglechair is provided with lugs 23, adapted to pinoli said laps to the rail ends, as shown in Fig. 3; but of course I do not limit myself to thismethod of holding said insulating mateterial 22 in place. The angle-chair may be provided with a corrugated under surface,as shown at 24: in Figs. 3 and 4.

In Fig. 4 is shown a modified form of the joint. It is in all respects similar to the joint above described, except that the two-part iishplate 7 8 is omitted and the packing and insulating material 14 is made of one piece and extends across the joining-point of the rail ends l l.

What I claim, and desire to secure by Letters Patent, is
