' RAIL-JOINT.

SPECIEIoA-TION forming 'part of Letters Patent No. 724,193, dated March 31, 1903. Application inea Augu'st 23,1902. serial No. 120,797. (No meer) To LZZ whom t may concern.- K l l Beit known that I, JAMES, J. MANT'ON, a citi- Zen of the United Statesresiding at Pittsburg, in the county of Allegheny and vState of Pennsylvania, have invented a new and useful lmp provement in Rail-Joints, of which improvement the following is a specification.

This invention relates to certain new and useful improvements in rail-joints, and has for its object to construct a rail-joint that is applied without the aid of the ordinary bolts and nuts for securing the same in position.

It is a well-known fact that the bolts and nuts as now employed in rail-joints are liable to become loose, so as to permit a loose joint, v which 1s not only a source of great danger,

held by means of securing-bars, one of which is provided with integral pins to engage through the web of the rails and extend into 'one of the fish-plates of the chair and the* lother of which is a wedgingbar which servesy to hold the first-mentioned bar securely in its position. Y

The invention therefore consists in thew -novel construction,combinatiomand arrangement of parts to be hereinafter more fullydescribed, and specifically pointed outA in the g 4 extending ledge 8. This securing-bar 11 carclaims.

In describing the invention in detail refer'- ence is had to the accompanying drawings, lforminga partof this specification, and whererin like numerals of reference indicate like {parts throughout the several views,in which- Figure 1 is a top plan view of my improved rail-joint. Fig. 2 is a side elevation of the same. Fig. 3 isa top plan view of the chair. Fig. 4 is an underneath plan view thereof. Fig. 5 is a transverse verticalsectional view of the joint in position. Fig. 6 is a'horizontal sectional view taken on the line 5 5 of Fig. 5. Fig. 7 is a detail perspective view of the wedge securing-bar and, Fig. 8 is a like view of the securing-bar which connects the two rails together.

Toput my invention i'nto practice, I provide a chair which may be made of cast-steel or other suitable metal, andas it may be 'cast can therefore be very cheaply manufactured. This chair consists of a base1,which carries an integral fish-plate 2, provided with openings 3, adapted to register with the openings provided in the web of the rail 4. `This `fish-plate closedlat the outside at the topv and at the bottom, the inwardly.- extending ledge 8, which forms the bottom of the channel or groove, being of a width sufficient to have its inner edge engage with the web'of the rail, and its lower face is shaped to conform to the upperface, of th-e rail base. In order to lighten the chair, the base 1 thereof is preferably cutaway, as shown at 9, there being sufficient material left at each end of the cutaway portion to form a saddle 10, upon which the rails 4 rest after they are inserted into position on the chair. .Previous to placing the rails 4 into position, asV shown in Figs. 1 andj2, I placei'n .the channel or groove 7 a securing-bar 11, which has its upper edge shaped to conform to the bevel on the under side of the tread of the rail and its lower edge shaped to -it the upper face of the inwardlyries integralpins 12, which engage through the apertures in the web ofthe rails and project into the registering openings 3 in the shplate 2. This securing-bar after the apertures have been brought into registry is movedlaterally, so as to cause the pins to engage in the apertures, as isshown'in Figs. 5 and 6, and after the securing-bar has been so positioned VI'iusert a wedge-bar 14, which is provided near its smaller end with a series of apertures 15, so positioned that one of the same will at all times be close to the' larger end of the securing-bar and receive a key 16, by means of which the wedge-baris prevented from working loose. The securing-bar 11, it

will be observed, is also wedge -shaped in form, and this bar and the wedge-bar 14 are inserted in the channel from opposite ends of IOO the latter, so that when both are in position the space between the outer Wall of the channel and the web ot' the rail is completely filled.

To remove the rails, the pin 16 is removed, the wedge-bar driven ont, at Which time the securing-bar 1l may be moved back into the channel, so that its pins will be disengaged from the apertures in the Webs of the rails and in the fish-plate 2, at Which time the rails may be readily Withdrawn from the chair.

The chair is providedalong the edges of its base with notches 17 to receive securingspikes, (not shoWn,) by means of which it may be secured to the cross-ties in the ordinary manner.

It will be noted that various changes may be made in the details of construction Without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the rails, of a chair having integral fish-plates one of which is provided With apertures and the other of which is provided on its inner face with achannel or groove, a securing-bar in said groove and having integral pins which project through the Webs of the rail and engage in the apertures in the sh-plate, and a Wedge-bar in said chan nel or groove for securing all parts in position substantially as described.

2. A rail-joint comprising a chair having an inside fish-plate to fit against the underneath side of the rail-tread andan outside sh-plate the top of which is flush with the tread of the rail, said outside fish-plate having a channel or groove, a securing-bar having integral pins engaging through the web of the rails and in the inside sh-plate, and a Wedge-bar in said channel for securing the first-mentioned bar in position, substantially as described.

3. A rail-joint embodying a chair having a base centrally out away with saddle-plates at each end, an inside fish-plate formed integral with said base and provided with apertures, an outside fish-plate having a channel or groove on its inner face, a Wedge carried by said outside fish-plate and engaging the ,web of the rail, a securing-bar having pins to engage through the Web of the rail and in the apertures in the fish-plate, and a Wedge-bar 5. A rail-joint embodying a chair, consisting of a base to receive the rails, an inside fish-plate formed integral with said base and provided with apertures, an outside fish-plate provided on its inner face With a channel or groove, Wedge-shaped securing-bars in said channel or groove and pins carried by one of said bars to engage through the Web of the rails and with the apertured fish-plate, substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

JAMES J. MANTON. In presence of y JOHN GRonTZINGER, M. HUNTER.
