To all whom it may concern:

Be it known that I, JAMES M. Burns, a citizen of the United-States, residing at New York, in the'county of New York and State of New York, have invented new and useful Improvements in RailsFastening Devices, of which the following is aspeciticationc.

This invention relates to rail fastening devices and the object of the invention is the provision of novel means whereby the rail may be secured to a concrete, steel, wooden or any other type of tie, and may be properly insulated therefrom, whereby current carried by the rail cannot become ground d or have ground leaks.

A further object of the invention is -the provision of av novel rail grip and lock which forms asuhstantially solid abutment against lateral or side thrust on the rail.

, Further objects of the invention will appear as the following specific description is read in connection with the accompanying,

drawings, which form a part of this applis cation, and in which I v z i Figure 1 1s a top plan VIBNV."

the line 33 of Fig. 1. Fig, 4 is a Similar section showing the rail grip and lock placed over the splice bars. Fig. 5 isa transverse section of a modified form. Fig. 6 is a detail transverse section showing a further modification. Fig. 7 shows a modified orm of wear plate.

Referring more partnularly to the drawings, 1 represents therail which, as is usual,

' is provided with ahead 2, web 3 andbase flanges 4, and 5 indicates a double T-shaped steel tie upon which the rail is adapted to rest. The Web flanges of the tie are provided with standard drill holes 6 and mounted on the top of the web flanges are a pair of wear plates 7 and 8, each having holes 9 therein of considerably larger diameter than the holes 6 and having interposed between the Specification of Letters Patent. Application filed January 21, 1911.

portions 15 adapted to engage over the base flanges 4 of the rail 1. The outer under edge of these grips is provided with a longitudinal enlargement 16 which holds the body of the grip separated from the wear plate for purposes of adjustment when the undercut portion becomes worn. The under surface of the grips, in practice, lies substantially parallel with the water plates while the upper surface thereof is inclined, as shown, and provided with serrations or corrugations 17 which are adapted to intermesh with similar corrugations 18 upon the locking washer or plate 19 whose upper surface, in. practice, lies parallel with the under surface of the grip and also with the wear plates. These locking washers or plates are apertured, as shown at 20, to permit the passage of the bolts 12. Each bolt 12 (and two are preferably used on either side of the rail) is provided with an insulating sleeve 21 extending from. the head 22, which directly engages the web flanges of the tie,

to the threaded portion 23 upon which a suitable nut 24: is threaded. An insulating washer 25 surrounds the bolt and is interposed betwen the washer or plate 19 and 'the nut24: which bears upon an. ordinary steel or ironwasher 25. As shown in Fig.

1, the separate nuts are connected together by a wilpe clip 26 which acts as a lock nut and prevents the; nuts from accidental turn- As shown in Fig. 4, the rail 1 has secured upon the opposite sides thereof, by means of the through bolts 27, the splice bars or fish plates 28 which are provided with bilSC flanges 29 adapted to overlie the baseflanges 4 of the rail 1. In this type of construe tion the insulated wear plates are identical with that shown in Figs. 1 to 3 and the bolts are provided with the usual insulating sleeves. The same type of grip and locking washer is employed but aslightly wedge shaped insulatingv washer 30 is thown interposed between the nuts on the locking washers. provided to accommodatethe slightly in-- clined arrangement of the upper face of the locking washers which isbrought about by the fact that the inner edges of the gripping plates are raised somewhat from their normal position on account of being seated upon the base flanges of the fish plates instead ofon the rails. It will be noted in this connection that the gripping plates are lts and the This type or washer also arranged farther away from the rails and that the slots 14 are of suflicient length to permit this adjustment.

In the modified form shown in Fig. 5, the wear plates 31 and 82 are separated, as is usual, by the insulation 33 which, in this instance, is formed in two partsso as to readily permit the outer edges of the wear plates to be bent: up and over the base flanges 4: of the rail 1, as shown. The rail grips or grippingplates in this type of structure are made somewhat thicker and have a greater under cut so as to lie over and directly engage the wear plates. The bolts 34 are free of insulating sleeves or washers and extend directly through the web flanges of the ties and the nuts 35 thereon rest directly upon the locking washers, the serrations or corrugations of the locking washers or gripping plates being retained as before described, although in both structures it may be omitted.

In the structure shown in Fig. (5, a slightly modified type of gripping washer is shown at 36, and is provided--with a countersink 37 in its .upper face to receive a. cup-shaped washer 39 of insulating material in which the nut 3., is adapted to rest. The insulation from the base of the rail and the bolt insulation the same as that described in Figs. 1 to 3. In thisfigure there is also shown a type of nut lock which is used when-only a single bolt is em iloyed, as will hereinafter be described. This type of nut lock shows a single strip of material 40 bent around the nut 39 and having its end abutting against the web 3 of the rail and provided with an insulating cap 1-1.

In Fig. l dotted lines a-b are indicated which are placed upon this figure to indicate that the gripping plates and the locking washers may be cut away upon this line so that only one bolt upon either side of the rail, need be employed. If this type of structure is used the wear plates shown in Fig. 7 are employed and the insulation will follow the outline in the wear plate.

- Having thus described the invention, what I claim as new is 2-- 1. The combination 'with a tie, of wear plates mounted thereon and having apertures therein, insulation arranged between said plates and having coincident apertures of smaller diameter, a rail mounted upon the upper wear plate, fastening devices mounted on the wear plate,'a belt for securing said fastening devices to the tie, and

a tube of insulation surrounding the bolt,

said bolt and tube of insulation passing through the apertures in the wear, plates and insulation and having the tube lying adjacent the insulation.

2. In combination, a tie, insulated wear plates mounted thereon, a rail seated upon the upper wear plate, oppositely disposed coacting wedge shaped gripping devices mounted upon the wear plate and engaging opposite sides of the base flange of the rail, and an insulated bolt for securing the gripping devices in operative position.

3. In combination, a tie, wear plates mounted thereon, insulation arranged between the said plates,-a rail seated upon the upper .wear .plate, wedge shaped grip-. ping devices mounted upon the wear plate and engaging the base flange of the rail, and insulated bolts for securing the grip ping devices in operative position and the wear plate on the tie.

4. In combination, a tie, Wear plates mounted upon the tie, insulation arranged between said plates, a rail seated upon the upper wear plate, wedge shaped gripping devices mounted upon the wear plate, and engaging the base flanges of the rail, a wedge shaped locking member seated upon the gripping devices and having its upper side parallel with the lower side of the gripping device :ind an insulated bolt passing through the gripping and locking devices and through a portion of the tie to hold the rail and wear plates. in position thereon.

5. In combination, a tiey Wear plates mounted upon the tie, insulation arranged between said plates, a rail seated upon the upper plate, a wedge shaped grip having a slot therein mounted upon the top Wear plate and engaging the base fla-ngeof the rail, a wedge shaped locking member mounted upon the grip and'having its thick.

end in opposition to the thick end of th't grip and with its upper side parallel with I the lower side of the grip, a bolt passing through a portion of the tie through the insulated wear plates and through the grip' and locking device, an insulating tube surrounding the said bolt, and an insulating washer arranged between the locking device and the bolt nut.

In testimony whereof I afilx mysignatiire. 110
