RAILWAY-TIE.

SPECIFICATION formingpart of Letters Patent No. 667,116, dated January 29, 1901.

Application filed June 2, 1900. Serial No. 18,891. (No model.)

To all whomit may concern:

Be it known that 1, JOHN W. COOPER, acitizen of thev United States, residing at Park Ridge, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Railway-Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railways, and more particularly to the joints, ties, chairs, and parts cooperating therewith.

In order to support the ends of adjacent rails against the load imposed thereon when a train is passing thereover, a beam or sleeper is provided and arranged parallel with the rail and preferably directly beneath the same, and the ties within a short distance of the jointeach way are placed upon the said beam. The chairs have adjustable connection with the ties to allow for variation in gage and have positive interlocking connection therewith, so as to prevent casual displacement.

The invention also consists of the novel features, details of construction, and combination of the parts, which hereinafter will be more fully disclosed and finally claimed, and for this purpose and also to acquire a knowledge of the merits of the invention and the structural details of the means whereby the results are attained reference is to be had to the appended description and the drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure l is a side elevation of a rail-joint, showing the application of the invention. Fig. 2 is a detail view of a part of the longitudinal beam or sleeper, showing the means for securing a tie thereto. Fig. 3 is a detail section about on the line X X of Fig. 1. Fig. 4 is a top plan view of a tie, showing the rails in position, one of the chairs being turned so as to admit of its clips clearing the foot portion of the rail placed thereon and the other ch-air being in position with its clips engaged over the foot portion of the rail. Fig. 5 is a detail view of the chair having the tie-clips formed by side extensions. Fig. 6 is a detail view of the chair having the tieclips stamped from the body of the chair within the longitudinal edges thereof.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The joint 1 between the ends of adjacent rails 2 is strengthened and connected in any of the usual Ways commonly resorted to in railroad construction. A short .beam or sleeper 3 is arranged parallel with the rails and preferably directly beneath the joint 1 and extends about an equal distance from opposite sides thereof. This beam or sleeper is about five to six feet in length, more or less, and is designed solely to support the joint and prevent the terminals of the rails from ivin wa under the wei ht of a train ass- 2D b p ing thereover. The beam or sleeper is of I form in cross-section, and clips 4 are pressed from opposite edges of the head-flange, so as to engage over the foot-flange of the ties 5. The clips 4 are provided in pairs, and the clips of each pair are diagonally disposed, as shown most clearly in Fig. 2, thereby-admitting of the base-flange of the tie being engaged therewith when turned so as to clear the inner edges of the clips, as will be readily comprehended.

The ties 5 are preferably of I form in transverse section, and the edges of the head-flange are provided near each end, at diagonally opposite points, with teeth 6 to cooperate with cogs 7 of the chairs 8 to form positive interlocking means for securing the said chairs upon the ties when properly positioned. Longitudinal slots 9 are formed in the head-flange of the ties to one side of the vertical or connecting web and are enlarged at one end, as shown at 10, to admit of the passage therethrongh of the head of the fastening-bolt 11. These slots 9 may extend parallel with the edges of the tie or be slightly inclined thereto, the latter providing means for compensating for wear and inaccuracies in mechanical construction, so as to insure a firm connection between the rail-clips 12 and the base-flange or foot of the rail.

The chairs 8 are provided with a pair of rail-clips 12, having a diagonal disposition,

and a pair of tie-clips 13, diagonally disposed, so as to engage with the flanges of the respective parts at different points in their length. The rail-clips 12 arepressed from the body of the chairs, and their inner edges incline, so as to provide ample clearance for the foot or base flange of the rail, as shown most clearly at the left-hand end of Fig. 4. A slot 14 extends a short distance from the inner end of each of the chairs and is adapted to coincide with the slot 9, so as to receive the fastening 11. This slot may be either straight or inclined. When the slot 9 in the head-flange of the tie is straight, the slot 14 of the chair cooperating therewith is inclined, and when the slot 9 is inclined with reference to the length of the tie the slot 14 of the chair is straight. As indicated most clearly at the right-hand end of Fig. i, the slots 9 and let overlap at theirinnerends, and when brought into true vertical alinement the clips are caused to engage the respective flanges of the parts with which they cooperate with a greater or less degree of pressure, so as to obviate any possible play. The cogs 7, provided to engage with the teeth 6, are bent portions of the metal forming the chair and are located, relatively, at diagonally opposite points. By turning the chair with reference to the tie, as shown at the left-hand end of Fig. 4, the cogs 7 clear the teeth 6, and the chair can be moved on the tie to the required position, and when the chair is turned .to 'bring the slots 9 and 14 into coincident relation the cogs 7 engage with the teeth 6 and prevent any longitudinal play or movement of the chair on the tie. IVhen the bolt or fastening 11 is placed in position and enters the slots 9 and 14, the chair cannot be turned, and its position is consequently fixed, even though the bolt should become loose. It is contemplated to secure the bolt or fastening by a nut-lock in any manner found most advantageous and convenient to preventits casual displacement after being properly positioned.

As shown in Fig. 5, the tie-clips 13 are side extensions of the blank from which the chair is formed and are bent so as to embrace the edge portions of the head-flange of the tie. Fig. 6 shows the tie-clips 13 pressed from the body of the chair in a similar manner to the rail-clips 12, the free ends of said clips facing inward. Should the tie-clips fit the head-flange of the tie in a loose manner, they can be tightened by striking them a smart blow with a hammer or like implement, so as to reduce the space formed between the said clips and the plane of the chair.

In constructing a line of railway in accordance with this invention the beam or sleeper 3 is located opposite the rail-joint and in vertical line therewith and the ties adjacent to the joint rest thereon, thereby preventing the joint giving way when pressure is brought perpendicularly thereon, as when a train is passing thereover. The provision of the clips for securing the ties'to the beam or sleeper reduces the cost of construction materially and obviates the formation of separate parts, which are liable to separate under vibration when the track is in service. The construction is likewise rendered durable and lasting and the parts are not liable to derangement and maintain a fixed relation under all conditions. If it be desired to have only one chair adjustable on the tie, the other chair is secured by its cogs engaging a single set of teeth of the tie. In this connection it may be well to state that the ties may be placed with the adjustable chairs at one side of the track or in alternation with the fixed chairs.

Having thus described the invention, what is claimed new is- 1. In com bination with a tie having a headflange, and a rail, a chair provided at diagonally opposite points with clips to engage opposite edge portions of the head-flange of the tie, and means for securing the rail to the chair, substantially as set forth.

2. In combination with a tie having a headflange and a longitudinal slot, a chair provided at diagonally opposite points with clips to engage opposite edge portions of the headflange of the tie and having a slot to register with the slot in the head portion of said tie, and a fastening to enter the slots of the chair and head portion of the tie, substantially as set forth.

3. In combination with a tie having its head portion formed with a longitudinal slot and a chair having diagonally-disposed clips to engage with the head portion of the tie and having a longitudinal slot to register with the longitudinal slot of the tie, one of the said slots being straight and the other inclined, and a fastening to enter the said slots, substantially as and for the purpose set forth.

4. In combination with a tie having teeth in opposite edges of its head portion at diagonally opposite points, a chair having diagonally-disposed cogs to make positive engagement with the said teeth and having clips adjacent to the respective cogs to engage with the edge portions of the tie, and means for preventing displacement of the chair when properly positioned,substantially as set forth.

5. In combination with a tie having its edge portions toothed at diagonallyopposite points, a chair provided with diagonally-arranged cogs to cooperate with said teeth and having clips adjacent to the cogs to engage positively with edge portions of the tie and also provided with diagonally-arranged rail-clips,and means for securing the chair to the tie, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
