INSUL'ATED RAIL JOINT.

Original applicationy filed September V6, 1921, Serial No. 498,609. Divided'and this application led November 30, 1921.

To all whom t may concern Be it known that I, ALFRED L. RUTHVEN, a citizen of the United States, residingl at Rochester, in the county 0f Monroe and State of New York, have invented certain new and useful Improvements in Insulated Rail Joints, of which thefollowing is a specification, reference being had therein to the accompanying drawing.

The present invention relates to insulated rail joints for use inrailw'ay signalling or train controlling apparatus, and this appli'- cationis azdivision of thefcopending application for patent on simplex train control filed September 6, 1921, Serial.No.-498,609.

The object off'the'invention is to provide a novel and improved insulated joint lfor the trailc rails, in order to obtain insulation which will'n'otbreak down, as well as efficiently supporting the rail ends and preventing the rail sections from creeping.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, whereinv Figure 1 is a Side elevation showing the improved insulated rail joint.

Fig. 2 is an enlarged section on the line 2 2 of Fig. 1.

Fig. 3 is a side elevation of a modied form of insulated rail joint.

One form of insulated rail joint is shown in Figs. 1 and 2, wherein the insulating plates or sheets 90 are disposed between the adjacent ends of the rail sections 91, and fish plates or bars 92 of wood or other insulating material are secured to the opposite sides of the rail webs by means of the usual bolts 93. Said sh bars are suliciently stout to assist in holding the rail sections together in alinement. Two pairs of side plates 94 are secured by the bolts to the bars 92, and the adjacent ends of said plates are spaced apart so as to be insulated from one another, with only the bars 93 extending from one rail section to the other across the insulation between the rail sectionsE The into the tie.

secured to the tie, which will fasten` the rail serial Na'sisro.

plates-94 havelower inturned flanges 975 to extend under the base flanges of the rail `sec-tions, and the flanges 95 of the two pairs of clamping plates have `depending abutments 96 disposed at opposite sides of the tie V97 which is disposed under the joint.

lAngle plates 98 arey preferably tted` on the tie 4over the upper corners tliereofso that the flanges 95 and :abutments bear against said plates, as seen in Fig..1. The abutments 96 of veach pair are secured together by transverse bolts 99 extending through them, and the abutments are secured to the tie 97 at the opposite sides by means ofilag screws 10.0 extendinglthrough the abutments and The'abutments are thus firmly sections down von the tie, and also prevent the creeping 'ofthe rail joint on the tie. The tie 97 is supported 0n a concrete sleeper or base 102 embedded in the roadbed, said sleeper or base having an upper groove or channel 101 receiving the tie, to retain the tie in place. Bars or shims 103 of wood Ior other suitable material are disposed in thechannel 101 under the tie 97, for cuslin ioning the tie and also supporting it at the desired height in either horizontal or inclined position according to the track. A plate 104 of insulating material is disposed under the ends of the rail sections on the tie 97 between the flanges 95, and is held in place by lugs 105 extending from the adjacent ends of said flanges and overlapping the ends of said plate 104.y With this construction, there is no metal extending from one rail section to the other, and the

parts

90, 92, 97 and 104 between the rail sections are all of insulating material, s0 that the insulation will not break down. The joint is also firmly supported and is prevented from creeping.

l disposed Abutments 96 are clamped to the rail sections and abut the opposite sides of the sleeper 102, to prevent the rail from creeping.

Having thus described the invention, What is claimed as new is zl. An insulated rail joint comprising spaced clamps for the end portions of the rail'sections having portions to extendunder the base flanges of the rails and abutm'ents below said portions to abut the opposite sides of a support on Which-said portions are 2. An insulated rail joint comprising spaced clamps Afor the end portions of the rail sections, each clamp having opposite side members With portions to extendunder the 'base anges of the corresponding rail section, said portions having depending abutments` to abut a support on which said -portions are disposed.

3. An insulated rail joint comprising 'spaced clamps for the end portions of the rail sections, each clamp having opposite side members with portions to extend under the base flange of ythe corresponding rail section, said portions having depending abutments to abut alsupport on which said portions are disposed, said abutments of each 4clamp being secured together.

An insulated rail joint comprising sh bars of insulating material 'to '-fit @the op-posite sides of lthe end 'portions of the rail sections, and clamps at the outer sides of said iish bars to engage the base flanges of the 'rail sections and adapted to be secured on. a support, said clamps of the tvvo rail sections being spaced apart.

5. An insulated rail joint comprising lfish bars of insulating material to iit the opposite sides of the end portions of adjacent rail sections, and spaced clamps 'to be secured to the rail 'sections at the 'outer sides of the .sh bars, with the 'sh bars clamped between the clamps 'and rai-l l'sections, said 'clamps being formed to be 'secured on support.
