HUNTING-TON, WEST VIRGINIA, A GORPORATIGN OF RALWAY-TRACK CONSTRUCTION.

Application filed March 22, 1924. Serial N0. 701,101'.

To f/ZZ 11i/tom it' may concern.' Y Y Be it known that I, HERMAN H. DIEHL, a citizen of the United States, residing at Huntington, in the county of Cabell and State of West Virginia, have invented a new and useful Improvement in RailwayfTrack Constructions, of which the following is a specification. f

My invention relates :to the securing of rails to metal ties, especially in the case of track construction for use in mines and general construction work; and more particu# larly to structures comprising rail-i'lange-engaging clips rotatable on the ties and adapted to be rotated into and out of rail-flangeengaging position. Y i

The ties as commonly provided are made of relatively thin gauge metal as compared with the thickness of the clips, and thus a greater area of frictional surface is presented to the pivoting rivet for theclip, by Y the wall of the rivet-receiving opening there in, than by the wall of the rivet-receiving opening in the tie, with `the result that in the rotation of the clip the rivet turns therewith and rotates in the tie. The metal of the tie being comparatively thin, as stated, repeated rotations of the clip soon produce such wear of the wall of tie'that objectionable looseness of the rivet therein results. i inrmines, especially coal mines, the objectionable looseness referred to occurs much sooner than in the case of the use of the structuie under other conditions, due to the contacting of the structure with sulphur water which enters between the rivet and the wall of the opening in the tie and thus produces corrosion, repeated rotations of the clip eX- posing fresh surfaces of the metal to such corroding action and oftentimes soon impairing the structure for satisfactory func tioning. My object is to overcome the above-cited objections incident to structures of the character described as hitherto provided, and insure the desired tightness of the rivet for a much greater length of time than hitherto possible.

llVhile my invention is applicable to all forms of rail-flange-engaging clips which are rotatably mounted on a tie for movement into and out of engagement with a side of the rail, have chosen to illustrate it as embodied in a structure corresponding with that the opening in thev Inxthe useof the structureV disclosed in United States Letters Patent No. 1,464,975 granted to me August 14, 1923. Referring to the accompanying drawing: Figure l is a view in side elevation of one end of a railway tie showing in position thereon a rail, represented in section, secured thereto by devices one of which is a rotatable clip in connection with which my invention is incorporated. Figure 2 is a plan view of the structure shown in Fig. 1. Figure 3 is a section taken at the line 3 on Fig. l and viewed in the direction of the arrow. Figure 4 is a plan view of the portion of the tie which is located directly below the clip shown at the left hand side in Figs. l and 2; and Figure 5, a plan view of the central portion of the clip just referred to.

My invention, generally stated, consists in so constructing and arranging the parts of the structure that the pivoting rivet for the clip will be prevented from rotating in the opening in the tie through which it extends, while permitting the clip to rotate upon the rivet. In accordance with the preferred embodiment of my invention these means comprise the formation of the hole in the tie through which the rivet-extends, of non-circular shape, whereby, when the rivet is driven in place to hold the clip to the tie, that portion of the rivet which extends through this opening in thetie will deform into noncircular shape in cross-section to more or less exactly conform to the shape of the opening in the tie, with the result of interlocking the rivet against rotating in the tie opening.

Referring to the particular construction shown, one end of a metal tie is represented at 6, thistie, which is formed of relatively thin-gauge metal, being of general U-shape in cross-section to provide the elevated railseating surface 7 and the supporting flanges 8 at opposite sides of the tie at which the tie rests upon the ground. An abutmentdevice for engaging the flange of a rail represented at 9, at one side of the rail, is indicated at l0, this abutment device being riveted to the tie by means of the rivet represented at 1l. In the particular construction shown the abutment l0 is designed to aiford a permanent rigid abutment for this side of the rail. At the opposite side of the rail 9 is a rail-ange-engaging clip 12, mounted on the tie in a manner to adapt it to be rotated into and out of the railange-engaging position shown in Figs. 1 and 2. The clip 12 is of the same construction as the clip 14 of said patent, and de tailed description thereof appears to'be unnecessary. The clip 12 is pivotally supported on the tie 6 through the medium of a rivet represented at 13, the clip 12 and the web 7 of the tie being apertured, as represented at 14 and 15, respectively, to receive this rivet. The aperture 15 in the web 7 is of Vnon-circular shape, in the particular construction shown it being in the form of an ellipse, andthe aperture 14 is circular. 'lhus when the clip 12 is riveted to the web by the rivet 13, the latter being preferably heated before being swaged into the condin tion shown in the drawings, the metal Vof the shank of the rivet where it extends through the opening 15 will be deformed out of circular shape into a shape more or less conforming to the shape of the opening 15, the rivet preferably being deformed into tight engagement with the wall of the opening 15, thereby producing an'interlock between the shank of the rivet and the wall of the opening 15 preventing the rivet from rotating in the tie. As the opening 14 is circular, the clip 12 may be rotated, as by driving it witha hammer, into and out of a position in which it overlappingly engages the flange of the rail.

lt will be Vreadily understood from the foregoing that by pivoting the clip on the rivet, as distinguished from pivoting the rivet on the tie as in the case of structures as hitherto provided, the tightness of `lit of the riveted parts under repeated rotations of the clip is greatly prolonged as compared with prior structures, this being of especial advantage, as above suggested, where the track construction is used in mines, particularly coal mines where it oftenV lies in contact with sulphur water the corroding eect of which is very objectionable.

While I do not claim that by embodying my invention in a track construction the vcorroding action of sulphur water contacting therewith will be avoided, -I do claim that by my invention the tightness of fit of the riveted parts will be maintained for a greater length of time, Vupon repeated rotations of the clip into and out of rail-flange'- engaging position, than in the case of structures as hitherto provided.

While I have illustrated and described a particular construction embodying my invention, l do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of my invention.

Vhat I claim as new, and desire to secure by Letters Patent, is:

1. In railway-track construction, the combination of a metal tie containing an opening, a rivet extending through said openings, said rivet being non-rotatable in said tie, and said clip being rotatable about said rivet.

2. In railway-track construction, the combination of a metal tie containing an opening, a clip containing an opening, a rivet extending through said openings, and means for preventing said rivet from rotating in said opening in saidtie, said'clip being rotatable about said rivet.

3. 1n railway-track construction, the combination of a meta-l tie containing a noncircular opening, a clip containing an opening, and a rivet extending through said openings and interlocked with the wall of said opening in said tie to prevent said rivet from rotating in said opening in said tie, said clip being rotatable about said rivet.
