RAIL-J OINT.

Specification of Letters Patent.

Patented July 1, l1919.

Application filed April 11, 1919. -Seria1No.289,186.

To all whom 'may concern:

Be it known that I, 4Gritoizen TAYLOR, asubat 7 300 Ridge avenue, Roxborough, in the county of Philadelphia and State of Pennsylvania, have invented new andouseful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to railroads and it has more particular reference to means for connecting together the meeting end sections of railroad rails and which are commonly known as rail joints.y

The main object ofthe invention is` the provision of a combined rail joint and chair which is novel in construction and in which is employed a pair of locking elementsy for `securing the abutting rail yends in `rigid alinement in relation to one another.

A further 1object of the `invention is the provision of a combined joining means and chair which permit of the longitudinal expansion of the rails under changing atmospheric conditions while at the same time any fall when rolling stock is passing thereover is effectively prevented.

A' still vfurther object of the invention is the provision of a combined rail joint and chair which .is of simple `and economical construction, few and readily assembled parts, and which can readily be applied to the extremities of the rails without the ne- Vcessity of forming holes therein, or which applied in the place of existing joining means when damaged or requiring repair or renewal. With the foregoing may be easily and other objects in view the'invention consists essentially in the Figure novel features of construction, combination, and arrangement of parts hereinafter fully A described and more speci.lly pointed out in l the appended claims.

In the further disclosure of the invention, reference is to be'had to the accompanying sheets of explanatory drawings, constituting a pai-tof this specification, in which similar characters of reference denote the same or corresponding parts in all the views, and in Ath.tough fa 'rail `joint and chair disclosing a proved lrail joint 1- is .a Vvertical sectional view .p

rail applied thereto, and incorporating a preferred form of the present invention.

Fig. 2f is a top plan View of the iinand chair.

Fig. 3- is a side elevation looking to the left hand in Fig. 1.

Fig. 4lis a vertical sectional view taken on the line 4 4 in Fig'. 1, with the rail ends removed and looking to the left hand in said figure; and

.5- 's a fragmentary detail sectional view hereinafter more particularly referredto. Referring more particularly to the drawings the numeral 10, designates a fragmentary portion of a tie or the like upon which the improved combined chair and joint, is adapted to be mounted.

The chair proper a, consists of a base 11, formed at that end thereof which is intended for disposition on the outside of the track with an enlargement 12, of the cross section shown clearly iii Fig. 1; that is to say it is extended upwardly and curves outwardly toward the end 13, of the base 11. The inner end of this enlargement 12 is formed with an undercut part 14, of a section which is adapted to receive one side 15, of the flanged base of a rail 16. Remote from and opposed to the enlargement 12, and at the other end of the base 11, there is formed an upwardly extending and inwardly inclined iiange or wall 17, between which and the web of the rail 16, there is disposed a slidable block or wedge 18. This block or wedge p formed as shown with a vertical `wall or face 19, adapted to bear against the Webs of the abutting rail ends, an opposed inclined Wall or face 20, of a taper to snugly and frictionally engage the inner inclined face of the upwardly extending flange 17 above referred to, and a longitudinally disposed undercut part 21, of a section to i'it the other side 15, of the flanged base of. the rail 16. Longitudinal holes or apertures, 22, may also be formed in the block or wedge 18, for lightening purposes.

It is to be noted that the inner longitudinal upper face of the base 11, is formed at its edge adjoining the undercut 14, and at a oint alining with the outer edge of the side base of the rail 1 6, with 18, is preferably 5% of the flanged slightly inclined depressions 23, so that any tendency to rocking of the track will not disengagethe block or wedge 18.

In order to provide an effective and simple means for retaining the block or wedge 18, firmly in place when the chair a, and rail ends are assembled I form a pocket 24, in the base l1, in which is seated a strong flat or leaf spring 25, that abuts the underside of said block or wedge 18, and forces the same upwardly so that the faces 19,20, thereof are constantly held in firm frictional locking engagement with the abutting web faces of' the rail ends and also the inner inclined face of the wall 17.

In some instances- I may also form a pocket 26, in the undercut part of the block or wedge 18 for the reception of a second flat or leaf spring 27, which is prevented from longitudinal displacement by having its ends abut chisel cuts or indents 28, made in the base flanges l5a of the abutting rail ends, as clearly shown in Fig. 5.

For the purpose of' effectively seating the chair a', after it has been applied to the rail ends and the block or wedge 18, driven into place, I provide a supporting plate 29, fashioned with a central depression 30, in which seats said chair a, and longitudinally extending up-stepped fianges 30', 30', which are formed with spaced enlargements 31, 31, of the same lsection and configuration as the enlargement 12, formed on the chair. A lip or upset liange 32, engages the outer edge 13 of the chair a, and a corresponding opposed lip or upset flange 33, is provided remote therefrom in the event it is necessary to reverse the position of the chair and dispose the block or wedge 18, on the outside of the track. Upset lugs 34, 34, are formed on the flanges 30, 30, at points convenient to prevent any longitudinal displacement ofthe block or wedge 18 as will be clearly understood on an examination of the Figs. 2 and 3, more particularly.

Spikes 35, serve to hold or secure the supporting plate 29, firmly on the ties 10, while additional spikes 36, are also used to clamp the sides 15'r1 of the flanged bases of the rail ends 16 firmly in place and it is to be noted that these latter spikes arelocated in opposition -to the enlargements 31, 31.

In use, the rail ends are engaged in the Vchair a, on the base 11, and against the enlargement 12, whereupon the spring 25, or

' springs 25, 27 are placed in position and the block or wedge 18 inserted, which locks the chair in place. The supporting plate 29, is then slipped under the chair a, from the outside of the track until the enlargements 3l, thereon abut the rail webs and the chair seated in the central depression 30, and between the lugs 34 whereupon the spikes 35, 36, are driven and the rail joint is complete.

It lis to be noted that the enlargements 12,

31, are formed with shoulders for firm engagement against the underside 37, of the ball of the rail 16, to serve as a support to' Vstrengthen the same and to prevent the fiattening of the abutting rail ends incident to the pounding of the wheels which pass thereon.

V-Vhen vdesired provision can be readily made for the insertion of insulation between the chair a, and rails 16,- in order to insulate the track from said rails.

From the foregoing description it will be readily seen that by my invention a very eective and readily applied rail joint and chair is provided which is adapted for new or old rails, while it can be just as easily employed in the case of a broken rail, in'asv much as the fractured ends can be brought together and securely held in place without drilling holes through the rail web.

Furthermore it will be readily seen that. the rails can expand and contract and the chair a, and supporting plate are also fastened in a manner to the cross-ties that will perm-it of expansion and contraction caused by the difference in temperature.

Obviously the length of the supporting plate and exterior configuration of the parts will be dependent upon service conditions, and while I have described and shown one practical Aembodiment of my invention, I wish it clearly understood that various slight changes may be made in the ydetails of construction without departing from the general spirit of' said invention the scope whereof is defined fby the appended claims.

Having described my invention, I claim,-

1. In a rail joint, the combination with the rails of a chair having an undercut enlargement at one side and an inwardly in- 105 clined opposed wall at the other side, an undercut block adapted to fit between the inwardly inclined wall and the web of the abutting rail ends, means for forcing said block Vupwardly into locking position, and a 110 supporting element for the chair having spaced enlargements adapted to aline with the enlargement on the chair.

2. In a rail joint the combination with the rails, of a chair having an undercut en- 115 largement at one side and an inwardly inclined opposed wall at the other side, an undercut block adapted to lit between the inwardly inclined wall and engage the webs of abutting rail ends, a spring seated in a 120 recess in the chair base and adapted to force the undercut block upwardly into locking position, and a supporting element for the chair having upset longitudinal flanges and spaced enlargements adapted to aline with 125 the enlargement on the chair.

3. In a rail joint the combination with the rails, of a chair having an undercut end largement at one side and an inwardly in clined, opposed wall. at the other eide, an una l@ dercut, block adapted to fit between the in- W'ztrdly inclined Wall and engage the Webs of abutting rail ends, a spring seated in a recess in the chair base and zt supplementary spring seated 'beneath the undercut portion of the aforesaid block said springs being adapted to force the block into locking position, a supporting element for the cha-i1' having upset longitudinal flanges and spaced enlargements adapted to aline with the enlargement on the chair, and means for preventing the longitudinal displacement of the undercut block when the parts are assembled.

In testimony whereof I aflix my signature.
