INSULATED RAIL-domi'.

Patented Oct. 9, 1906.

pplication filed :Tanuary 11, 1906. Serial No. 295.534.

To a/Z Z whom t may con/cern.-

Beit known that I, WILLIAM F. Bossnn'r, a lcitizen of the UnitedStates', residing at Utica, in the county of Oneida and Statevof .New York, have inventedcertain new and.,

` provide or the insulation of rails Aby a durale and effective device combining strengthwith simplicity of parts and providing means -whereb a portion of the insulating material,

especia ly the parts at the ends of the rails, which, owing to their bearingfsurfaces and the heavy strain to which they are subjected by the pounding action of wheels passing over them, are quite likely to become defective and form a short circuit from one rail to another or continuous rail and may be readily replaced without disturbing the joint or rails in anyway. v My invention relates, further, in the construction of a device of this nature whichwill Alated aracter of the'joint, andto this end the invention plrovides not'only a completev insulation for t e base, web, and contiguous ends of the rail, but also'for the boltsl and different parts connected therewith.

My invention consists, further, inthe pro` vision of means whereby greater durability `may be secured to the insulated railLjoint and more security to the railway-track than the ordinary insulation' in use, thereby prolonging the'effectivedifetime-o the insulating.; material used, asftheparts ofthe' insulation.;l

Kliable to disinteqrationand destruction of other parts'may be easily replaced, while the' ^same romthe chair. The bo remaining parts'oftheiinsulating material' Q lfi l. the jointf itself may not be disturbed, thereby reducing the cost of construction and maintenance ol the line. A f

` My invention is illustrated Yin the accompanying drawings, in which' Figure 1 Vis a perspective view of my im` proved -re,il-joint showing the insulation between the rails and between the various parts.

\ Fig'. 2 is a cross-sectional view through Fig.

\1. Fig. 3 is a perspective view of a slight .n iodiiication` the construction, showing two halfcylindrical pieces of insulation under the tread o1c the rail in place of the form shown in Fig. l. Fig. 4 is 'a cross-sectional view ot Fig. 3. Fig. 5 is a sectional view showing a slight modification. Fig. 4 6 is a perspectivegview of a stillvfurther modification of the construction of the invention, showing one ofthe webssections of the lates fas integral with the bottom portion. p I ig.- 7 is a cross-sectional view through Fig. 6, and Fig. 8 is a sectional view of a slight mod ification. Fig. 9 is a detailed view of modification of my invention.

Reference now being had to thedetails of the drawings by numerals, l designates the railway-tie upon which therails are adapted tobe held in anyv suitable manner. Each rail has a tread portion 2, web 3, and ab'ase 4, and said web portion is provided with aseries of apertures to receive the bolts 5. y

Referring to- Figs. 1 and 2 of the drawings, I have shownl email-chair 6, made of a single ,pieceof metal, which surrounds the base of the rail and which has two upright portions rails with slight spaces intervening between. Said upright portionsare provided with apertures adapted to register with vthe apertures formed in the webs of the rails and through which the bolts `5A pass, "Wooden strips 7, having-'apertures' to receive the bolts 5 and capable of slight resiliency to permit of vtight clampingof saine upon'the web portions of the rails and still allow. suiiciently for eXpansions and contractions of the rails are placed in the. spaces intermediate the upright web portions ofthe l.chair and 4web portions'of the rails. A suitable insulation 8 is placed upon positioned on either ,side of .the webs of the the upper surface of the bottom of the chair and upon whichA the bases Iof the rails rest,

and insulating-stri Afs'Q are placed upon'the upper inclined :sur aces of-Sthe langesof the bases oi the frails to thoroughly insulate the :fthe parts together are mounted inY flanged s which hold l faces of the tread portions o1 the rails.

while washers 12 are interposed between the nuts and the sleeves and also between the heads of the bolts and atqacent insulationsleeves. In the construction shown m Figs.

f l and 2 of the drawings the upper ends of the webs of the chair are inclined in planes substantially at right angles to each other and form supports for the replaceable insulationstrips 13, the upper and inner faces of which insulation-strips are adapted to contact, respectively, with the under surfaces of the treads oi' the rails and the opposite faces of the webs of the rails.A It will be noted that the contact-surfaces of said insulation-strips conform to the inclined. endsof the web portions oi the chair, and when the n1: ts upon the bolts are tightened a wedging action is efl'eeted intermediate the chair ends and the insulation-strips 13 whereby the latter may be clamped secnrely against the rails.

In Figs. 3 to 5, inclusive, I have shown the upper ends of the web portions of the chair as cupped longitudinally to receive the insulation-strips 14, which are preferably converted upon their4 surfaces which engage said cup portions, while their upper edges are inclined and adapted to contact with the rnc er sur- In 'this modification 'an insulation-strip 15 is shown ot' a single piece and entirely surrounding the ianges and webs of the rails adjacent to their meeting ends and the insulationsleeves 16, which receive thebolts 5, are

4shown as extending 4through the web, portions of the chair and also the insulation-strip 15, bearing against the opposite faces of the web of the rail, while bars, preferably of a wood iibcr 17, are held in contact with the outer faces of the web portions of the chair by means of the nuts and heads of the bolts and ianged portion of said sleeve. In Fig. 5 of the drawings the construction of the web portions of the chair slightly differentiateV from the form shown in Figs. 3 and 4 in that the upper parts of the webs of the chair are somewhat thicker, and instead ofthe web being bent as shown in Fig. 4 recesses are formed for the reception of th insulation-strips 14.

Referring to Figs. 6, 7, and 8 will be seen a still different modified form of my invention in which instead of having the chair made of a single piece oiE metal I form the same in two parts, (designated by

numerals

18 and 19,) the former of which has one end'ZO cupped, as shown in the other figures, for the reception of the insulation-strips 14 and bends about the flanges and bottoms of the rails and has the insulation intermediate the same and the rails. A portion of section 1S of the chair is bent at right angles ,ad j acent to corresponding edges of the flanges of the l rails and atthti upper edge of the vertical portion thereof is turned to form a roll 21 designed to engage over a rib 22, formed rpon the outer edge of the section 19 of the chair, as clearly shown in cross-section in Figs. 7 and VBolts 5 are passed through the insulationsleeves 16, and the assembled parts of the adparatu s are held. secrrely clamped together by means of nuts 11 upon the bolts. in Fig. S I have shown slightly-modiiied iorm of bar 23', which instead of being solid, es shown in Fig. 7, is lormed oi a resilient metal which is -bent upon itself forming two resilient wings. which are adapted to yield slightly and designed to hold the upright portions ot' the chair-sections in clamping relation` In Fig. 9 I have shown a cross-sectional view illistrating a still different modification oi my invention, in which one of the chairsections 19 is bent uponitsell and combining with the piece the parts which are illustrated in Fig. 8 as being made of two parts, and the upright portions of the chair-section are provided with `registering apertures through which the bolt 5 passes 'and held by the bolt and nut thereon in clamping relation against the insulation which contacts with the web of the rail.

From the foregoing it will be noted that by the provision of the apparatus shown and described means are afforded for thoroughly 'insulating rails of a railway from metallic {ish-plates or chairs supporting the rails, also insulation means being afforded for the adjacent ends of' the rails where theyare supported in a common'ehair. By the provision of the means shown parts of the insulating means at the ends of the rails which are subjected to the most wear incident to the heavy strain of the pounding action of th'e wheels passing over the ends of the rails may be easily removed and replaced without disturbing the joints or rails.
