JOHN F. FORSYTHE,

OF BLOOMINGTON, INDIANA.

BAIL-JOINT.

Specification of Letters Patent.

PatentedNom-Q, 1915.

Application filed May 2, 1914. Serial No. 885,994.

' 'To aZZwhom it may concern:

' citizen of the .devised fish bed therefor,

' rails as at present lowing are first placed with Be it known that 1, JOHN F. FORSYTHE, United States, residing at Bloomington, in the county. of Monroe and State of Indiana, have invented certain new and useful Improvements in Rail-Joints, of which the following is-a specification.

' y inventionrelates to improvements in railjoints and more particularly to such a device described and claimed in a patent issued to me May 13th, 1913, bearing #1,061,907.

As its primary object the invention contemplates an improved and simplified structure including a non-metallic filler or splice bar so arranged. with respect to a specially this arrangement, as will appear hereinafter, greatly reducing the noise incident to the passageof rolling'stock over improperly joined.

The invention as a further object aims to provide a rail joint wherein the fillers or splice bars are so arranged relatively to the rails and to the fish plates as to bear against the former throughout their entire length and to maintain the latter in slightly sp'aced relation to the rails, thereby increasing the bending resistance of the joint.

The above and additional objectsare accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the t'ol specification and then more particularly pointed out in the claim which is appended hereto and forms a part of this application.

In describing my invention in detail reference will be had to. the accompanying drawingswherein like characters denote like-or corresponding parts throughout the several.

views, and in which Figure l is a view of a rail joint in cross section; Fig. 2 is a section on the-line 2-2 of Fig. 1; and, Fig. 3 is a d tail perspective view of one of the filler bars.

Referring now to the drawings by numerals, l narv railway rail. The rails 1 to be joined I their adjacent terminals 1n engagement. fish or'splice plates 2 being arfiinged, one upon each side of the meetlng ends of the rail. The fish plates L are so formed as the tread portion of the rail as indicated at 3 and to rest upon the upper face of the plate as'to form ,an adhesive designates as an entirety an ordi to bear against the under side of rail base as indicated at 4, the said plates loclred against longitudinal movement when so joined. The manner in which the bolts that in my former a are arranged having in m former patent above mentioned, further disclosure relative thereto, would be unnecessary. r

The inner or adjacent faces of ,the fish plates 2 are longitudinally grooved or concaved as indicated at 6, each groove or concavity receiving a non-metallic, (preferably wood) filler or splice bar 7, one longitudinal been fully described 7 edge of which is shaped to conform to the configuration of the said groove or concavity and the other' face of which isv substantially flat to bear, as illustrated in Fig. 1, against the web of the said rail. Openings 8 extend transversely of the filler 7 through which the bolts 5 extend. It will be noted patent the respective terminals of the fish plates 2 are cutaway to expose the base flange of the rail. This feature havingbeen found objectionable, the

fish plates 2 of my present device are so constructed as to engage the base flange of the rail throughout the entire length of the former to strengthen the rail joint and to adcllitionally braoethe tread portion of the rai I From the foregoing, taken in connection with the accompanying drawings it is apparent that the adjacent faces of the fish plates 2 are so arranged relatively to the web of the rails as to extend in spaced relation thereto, out above, reducing to the minimum the noise incident to the passing of rolling stock over the adjoining ends of the rails. It is also apparent that by so constructing the fish plates as to rest upon the baseflange oithe rail and to engage the under side of the tread portion thereof, the bending resistance of the rail joint will be inc msed; and th at by constructing the splice bars or fillers 7of material other than metal, the sound caused by the pounding of the wheels upon this arrangement, as pointed.

the rails is deedened without in any "Way decreasing theefiieiency of the joint.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in'the above description, as the preferred embodiment,-is the most etlicient and practical, yet realizing that the conditions concurrent with the adoption of my device Will necessenily vary,

'I desire to emphasize the fact that various minor changes in details of; construction, proportion and arrangement of parts may be resorted to, When required,- Without sacrificing any of the advantages of m invention, as defined in the appended claim.

Having thus fully described my invention, whatl claim as new and desire to secure by Letters Patent, 1s:

In a reil'joint, fish plates adjustable to;

- Wnrd and from the Web portion of the 'ail,

the top longitudinaledge of each afinally being grounded. to contact when in inee eee,

portion of the tail to aiford the inner face of each fish pletebeing longitudinally conceved throughout its length, a

filler of Wood fitting "each concavity, the filler being of a sizeto mpintain the inner face of each fish plate in spaced relation to the said Web portion of the rail and having a smooth inner face adapted for direct engagement with the said Web portion of the rail and a convexed outer face shaped to fit the concavity aforesaid, the engagement between thefiller'end filled space between and the tail, and :means maintaining the fish plates immovable i'elativelyto the rail in testimony WhereofI afiix my signature in presence of two Witnesses. y
