RAIL-SUSTAINING BAR AND PLATE.

SPECIFICATION forming part of Letters Patent No. 611,474, dated September 2'7, 1898.

Application filed October 22, I897. Serial 655,992. (No model-l d To all whom it may concern: I

Be it known that I, WILLIAM GOLDIE, a resident of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Rail- Sustaining Bars and Plates; and I do hereby declare the following to be a full, clear, and exact description thereof. I

My invention relates to rail protecting and supporting bars or plates; and it relates generally to the same class of bar or plate as described in an application filed by me May 17 1897, Serial No. 636,902, in which the plate has diagonal prongs at the end and flanges extending longitudinally thereof and transversely to the rail as it rests upon thesame. An important feature in this rail-sustaining device is to protect the same from the entrance of water, and so to prevent the rotting of the wood where the tie is cut by the prongs or flanges thereof; and the object of the present invention is to provide a plate in which the parts which cut across the fiber of the tie will be protected by the body of the rail.

To these ends my invention comprises, generally stated, a rail-sustaining bar or plate having flanges extending longitudinally thereof and having between the ends of the bar prongs or portions of the flanges extending at an angle to said flanges, said angle portions extending toward and at opposite angles to each other, these prongs or portions of the flanges being preferably bent inwardly and being preferably made at only a slight departure or angle from the main flanges, so that while obtaining a hold to sustain against lateral strain they do not sever any great portion of the wood fiber.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanyin g drawings, in which-- Figure 1 is a perspective view of the railsustaining bar. Fig. 2 is a bottom view of the saine. Fig. 3 is a cross-section on the line 3 3, Fig. 2. Fig. 4 is a perspective viewillustrating the position of the bar with relation to the rail and tie. Fig. 5 is a perspective view of the invention as applied to a wearplate.

Like letters indicate like parts in each of the figures.

I preferably employ the invention in connection with a rail-sustaining bar as distinguished from a plate,such"bar being made sufficiently narrow and rigid to be forced bodily into the tie, as shown in Fig. 4, and to give to the rail a bearing upon the body of the tie as well as upon the rail-sustaining bar. The invention may, however, be employed in the form of a regular tie-plate, as shown in Fig. 5. The bar has the same general construction as that set forthin theapplication Serial No. 636,902, having a body portion a and the shoulder b to sustain the rail against lateral movement, said shoulder being formed by bending up the body of the bar, and the longitudinallyextending flanges c, which extend out beyond the shoulder 17. The bars employed can be formed by rolling, and the flanges 0 can be rolled to a comparatively sharp edge, as illustrated. At some point between the ends of the bar prongs or angle portions 61 are formed, such prongs or angle portions being preferably formed from the bodies of the flanges c and being preferably formed at only a slight angle to such longitudinal flanges, so that, while providing for lateral resistance, they do not cut across much of the fiber of the tie, it being understood, of course, that the flanges c, which extend longitudi nally of the bar, enter the wood of the tie longitudinally of the fiber and hold therein by their frictional action without cutting across the fiber. These angle portions or prongs (Z do out across part of the grain, but while so doing are preferably formed only at slight angles, so that but little of the fiber is out, only sufficient to give the necessary lateral hold of the bar upon the tie to resist the lateral strain on the rail. These angle portions can be formed either when the metal is hot or cold, being formed in the bar in the rolling operation when it is hot or by suitable pressing or shearing mechanism when it is cold. The two flanges d (l approaching each other, as shown in Figs. 1 to 4, can be con nected to the longitudinal flanges c and to each other or can be formed separate, the inner ends of the flanges being separate, as indicated by dotted lines'at 6; Fig.1. It' is preferred that the two angle. portions f or flanges shall be connected, as this gives greater strength to the same where they are formed by pressing the longitudinal flanges inwardly. It Will be noticed that these angle portions which approach or extend toward each other are bent at opposite angles, so that the ends of these angle portions can be connected, as distinguished from the bending of them at the same angle, in which case they would extend away from each other. Such placing of the angle portions enables me to obtain a strong hold upon the tie by means of the angle portions of the flanges, while it makes possible the placing of theseangle portions entirely under the body of the bar or plate, so that the cut made across the grain is protected from the entrance of water, which prevents the rotting of the wood, and such construction has the further advantage, whether the flanges project under the plate .or outwardly from the plate, that they can both be bent from the main body of the flange at a single operation.

In Fig. 5 the invention is illustrated as applied to a rail-sustaining plate and as having the angle portions turned outwardly instead of inwardly, the longitudinal flanges f having the outwardly-extending prongs or flange portions g formed between the ends thereof.

The manner in which the rail-sustaining bar is used is illustrated in Fig. 4, the bar being pressed downwardly into the body of the tie, so that the top face of the body a is about on a level with the top of the tie, so that the rail is supported and cushioned on the tie-body as well as on the bar. As the bar is pressed down into the tie, in addition to the frictional hold obtained by the longitudinal flanges, the angle portions d cut to some extent across the grain or fiber, which abuts against the same on both sides of the angle portions, so that a positive hold upon the tie against lateral strain on the rail is obtained, while in addition to that the plate can be made lighter on account of the employment of the longitudinal flanges c, and these flanges, on account of their long frictional contact with the fiber of the tie, obtain a strong frictional hold thereon. At the same time the rail-base entirely covers the portion of the plate which cuts across the grain or fiber of the tie and covers that portion of the fiber which is so cut and protects it from the entrance of water or moisture, so that there is not so great liability of such portion of the tie rotting out as where the part of the grain which is cut across is exposed directly to the contact with moisture. The angle portions may be formed at any point between the ends of the bar and over which the rail extends. In the form shown in Figs. 1 to 4 that part of the tie which is cut across by the angle portions of the bar is still further protected because the angle portions extend inwardly and the body of the bar overhangs such angle portions, as at m, and protects them, in addition to the protection given by the rail, having the angle portions extending toward and at 0pposite angles to each other. In addition to the advantages in manufacture above referred to one angular portion is enabled to work with the other angular portion in resisting the lateral strain on the rail, because the two angular portions are close to each other, and as one portion presses against the fiber cut by it the other portion presses against the fiber out at the opposite angle, but close to the same, the two combining together to obtain a strong hold upon the tie.

In the use of the tie-plate shown in Fig. 5 the action is substantially the same, except that the plate is not forced entirely down into the tie and rests on the top thereof, and, further, that where the angle portions or prongs extend outwardly beyond the plate they are not so well protected by the rail as where they extend inwardly. So far as holding to the tie, however, and of being protected from water and moisture by the rail extending over the flanges are concerned the action is practically the same.

The bars or plates can be made rapidly by rolling the flanged bars or plates and bending the. angle portions either when the metal is hot or cold and shearing and bending up the shoulders to sustain the side pressure of the rail.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

1. A rail-sustaining bar or plate having a flange extending longitudinally thereof, and

having between the ends of such flange portions bent at an angle to the main body thereof, said angle portions extending toward and at opposite angles to each other, substantially as set forth.

2. A rail-sustaining bar or plate having flanges extending longitudinally along the outer edges thereof, and having between the ends of the flanges portions thereof bent inwardly at an angle to each other and to the main bodies of the flanges so that the bent portions of each flange extend under the body of the bar toward the bent portion of the other flange, substantially as set forth.

3. A rail-sustaining bar or plate having a flange extending longitudinally thereof and having between the ends of the bar portions of said flange bent at an angle to the main body thereof, said portions extending at opposite angles to each other, and the inner ends of said angle portions being united, substantially as set forth.

4. A rail-sustaining bar having flanges extending longitudinally thereof and having at one end a shoulder bent upwardly out of the body of the bar, while the flanges extend parallel with each other beyond said shoulder, substantially as set forth.

In testimony whereof I, the said WVILLIAM GOLDIE, have hereunto set my hand.

WILLIAM GOLDIE.
