Specification of Letters Patent.

Application filed July 9, 1914. Serial No. 849,906.

To all whom it may concern:

Be it known that l, GEORGE H. MARTIN, a citizen of the United States, iesiding at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented a new and useful Improvement in Rail-Joints, of which the following is a specification.

rlhis invention relates to rail joints, and one of the principal objects thereof is to provide a joint so constructed as to securely maintain the rail ends in position, without the use of bolts and nuts, which as is well known, have-'av tendency to become loosened by the vibration given the joints upon passage of rolling stock thereover.

Another object of the invention is to provide a joint including a base plate adapted to underlie the rail ends, and fish plates adapted to be secured to the base plate, the fish plates being provided with braces,ineans being provided for securing the parts together without the use of bolts and nuts.

A further object of the invention is to provide a joint of the class described, which will be simple, durable, efficient in operation and inexpensive to manufacture.

With these and other objects in View which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which like characters of reference indicate like parts throughout the several figures, of which- Figure l represents a plan view of a portion of railroad track showing my improved railjoint in place thereon. Fig. 2 represents a vertical transverse sectional view taken through the joint on the plane indicated by the line 2-2 of Fig. 3. Fig. 3 represents a vertical sectional view taken longitudinally ofthe track on the plane indicated by the line 3-3 of `Fig. 1', showing a portion of the joint in inside elevational view. Fig. 4 represents a plan view of the joint, the rail web being shown in section, and the inside fish plate having been removed. Fig. 5 represents a vertical transverse sectional view on the plane indicated by the line 5 5 of Fig. 1. Fig. -6 represents a top plan view 'of the brace engaging end of the inner plate.

Referring more particularly to the drawing, each joint includes a fiat base plate 5, having an upwardly extending flange 6 formed along one edge thereof, said plate adapted to underlie and form a seat for the base flanges of the rail ends, and as indicated in Fig. l the base plates are arranged so that the flanges 6 are disposed on the outer sides of the rails.

An outer fish plate 7 is secured to base plate 5, and has an upper portion 8 embracing the web 9 of the rail ends, and a lower portion 10 which engages upon the outer base fiange 11 of the rail ends, said portion 10 entending beyond the base fiange 1l to provide a shoulder 12 disposed between the base fiaiiges 11 and the flange (i. Disposed upon the outer fish plate 7 at its ends and at its central portion, are braces consisting of substantially heavy web portions 13 having formed integrally therewith oppositely extending fianges 14 which are of an angular shape and adapted to snugly fit upon the outer face of the sli plate 7. The braces are secured at their upper portions to the fish plate 7 by means of rivets 15 extending through portion 8 of said plate and through the upper portions of the brace anges 14. The lower portions of the braces are secured to the outer fish plate 7, by means of rives 16, which rivets extend through the lower portions of the brace flanges 14, through the shoulder 12, and through the base plate 5 adjacent flange 6, whereby to thoroughly secure the outer fish plate to the base plate. at the sime time serving to secure the braces to said outer plate. The fiange 6 is of such a height as to embrace and act as an anchorage for the outer lower edges of the fish plate, braces and brace flanges. i

rllhe inner fish plate 17 which in cross section is similar to plate 7, is removably positioned upon base plate in such manner as to engage the inner faces of the rail web and base flange. To one end, and to the central portion of the inner plate 17, are secured braces 18 provided with brace fianges 19,y

which braces and flanges are similar to those on plate 7, and the brace fianges 19 are secured to the inner fish plate at the upper and lower portions by means of the rivets 20 and 2l respectively, and intermediate the end portions by the rivets 22. None of the rivets securing the inner plate and braces together extend through the hase plate 5, since the inner fish plate as stated before is movably positioned on said base plate, so that the rail ends may be engaged against the outer fish plate and base plate when putting the joint in place.

Secured directly to the base plate 5 at one end thereof, and in such position as to be disposed on the inside of the adjacent track rail, is a brace 23 which is similar in shape to the other braces, and which is provided on one side adjacent the end of the base plate, with a flange 24. The flange extends the length of the brace 23, and on the opposite side is a shorter flange 25, which is of a length to extend between the adjacent longitudinal edge of the brace plate and the adjacent edge of the base flange of the rail, said flanges 2t and 25 being secured directly to said base plate by means of rivets 26. The bottom and side edges 27 and 28 respectively of brace 23 are spaced from the adjacent faces of the rail flange and web, a distance equal to the thickness of the inside fish plate 17, so that the end of' said plate not provided with'one of the braces 18, may be inserted between brace 23 and the rail, in assembling the joint. The end of fish plate 17 adjacent brace 23 is cut away at 29 to engage the edges of the flange 25, and at 30 to abut against the inner edge of the flange 24, where the latter depends below the lower edge 27 of the brace.

The outer fish plate -7 is provided with openings 31, which openings are in vertical alinement with similar ones in the base plate 5, for receiving rail spikes 32 whereby the outer side of the joint may be secured to the cross ties 33. As indicated in F ig. 4 a portion of base plate 5 disposed on the inside of the'rear ends is provided with similar spike receiving openings 34C. The openings in the base plate on each side of the rails are adapted to register with notches 35 formed in the edges of' the base flange 11 of the rail whereby when the spikes are in place they will engage said notches to prevent longin tudinal movement of the rails relative to the base plate. rIhe inside fish plate 17 is provided with spike receiving openings which when the spikes are driven home are brought into alinement with the openings 34, the relative position of the openings in the inner fish plate and base plate being such that during the operation of driving the spikes, said spikes engage the inner edges of the fish plate openings and the outer edges of the base plate openings whereby said sh plate is forced into rigid engagement with the rail as the spike is driven. l p

vCarried by the outer fish plate 7 are headed rivets 36 which are adapted to be extended through openings 37 in the rail web 9, and through registering openings in the upper portion of the inner plate 17, the function of rivets 36 being to prevent longitudinal movement of the rail ends relatively to the joint. And by reason of the pro vision of these rivets the spike receiving openings may be so disposed'tli-.it the spikes do not engage thc rail base, if so desired.

A joint constructed according to my invention may be comparatively cheaply manufactured, and by reason of the absence of bolts and nuts which might become loosened by vibration the joint provides an eX- tremely safe connection for the rail ends. Further advantages accruing to the joint are the facts that it may be installed in a comparatively short time, and without the requirement of special tools or of skilled labor, and that no more attention or upkeep is necessitated than that which is ordinarily required in the proper care of a railroad track.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination and arrangement of parts thereof as do not depart from the spirit of the invention and the scope of the appended claims.
