TANNES SIVERTSON, OF TACOMA, WASHINGTON.

RAILROAD-TRACK.

To all whom it may concern:

Be it known that I, TANNES SIVERTSON, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of IVashington, have invented new and use ful Improvements in Railroad-Tracks, of which the following is a specification.

This invention relates to railroads and it has particular reference to the track, broadly including the ties, the rails and the connecting means.

The invention has for its object to provide an improved railroad track which shall be simple in construction, easily laid and repaired, and in which the rails shall be held with absolute security against splitting or displacement under the stress of traflic.

With these and other ends in view which will readily appear as the nature of the invention-is better understood, the invent-ion consists essentially in an improved construction of a metallic tie whereby the rails shall be firmly and securely supported exactly in the desired position.

The invention further consists in a special construction of an improved rail adapted to cooperate with the specially constructed tie.

The invention further consists in simple and improved means whereby the tie and the rails may be firmly and securely connected together..

The invention further consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being however understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the appended claims may be made when desired.

In the drawings: Figure 1 is a top plan view of a railroad track constructed in accordance with the invention. Fig. 2 is a side elevation of the same. Fig. 3 is an end view. Fig. 4 is an enlarged view in elevation of one end of the tie showing also, in section, a rail about to be seated upon the tie. Fig. 5 is a similar view showing the rail partly seated. Fig. 6 is a similar view showing the rail completely seated and secured by means of a special key. Fig. 7 is Specification of Letters Patent.

Application filed May 12, 1911.

Serial No. 626,683.

a side elevation showing the locking device employed where the rail ends meet. Fig. 8 is a top plan view of the same with parts broken away. Fig. 9 is a transverse sectional view of the same.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved railroad tie A is made of metal, preferably of pressed or stamped steel, although. other suitable material may be employed, and the device may be formed by casting. In its preferred form the tie includes a base 1 and an upstanding portion constituting a flange or web 2, said base being relatively narrow intermediate its ends and wide at the ends thereof as will be plainly seen in Fig. 1 of the drawings, it being obviously desirable to make it relatively wide at the points where the rails are to be supported. The general shape or contour, however, may be varied according to the nature of the road bed and other circumstances. The web or flange 2 is provided with terminal raised portions 3, 3, each of said raised portions being provided with a rail receiving notch or recess 4:. These recesses are obliquely disposed, extending downwardly and inwardly "in the direction of the middle portionof the tie, each recess having a conveXly curved inner wall 5, a concavely curved outer wall 6, a flat bottom 7 and an acute angular notch 8 forming the angle between the bottom and the outer wall. Adjacent to the upper extremity of the outer wall there is also formed a notch or recess 9 adapted to constitute a seat for the rail head as will be presently described. The rail B which is used in connection with the improved tie is formed with the ordinary head 10 and web 11, but the flange 12 extends only in one direction from said web, that is to say, inwardly with reference to the tie. At the lower end of the web 11 upon the outer side of the latter there is formed a projecting portion or rib 13 adapted to cooperate with a securing device or key 1 1 as will presently appear.

In assembling a rail with a series of tie which have been previously placed upon the roadbed, the desired distance apart, the rail is first supported as seen in Fig. 4:, by inserting the flange 12 into the recess i, the web of the rail being meanwhile supported upon that portion 3 which forms the inner wall of the recess. The rail may now be tilted into the recess as seen in Fig. 5, the rib or heel portion 13 being guided over the concavely curved outer side wall 6 until the bottom of the rail flange becomes seated upon the fiat bottom portion 7 of the recess. The edge of the flange 12 will now be fitted in the acute angle between the lower end of the convex side wall 5 and the bottom portion 7 and the key or wedge member 14: is now driven in the angular notch 8 between the inclined face of said notch and the inclined face of the rib or heel portion 13, thus locking the rail very securely in position. The projecting end of the key may be bent to prevent its being accidentally withdrawn.

Wherever the ends of the rails meet or join it is proposed to employ a locking device substantially as illustrated in Fig. 7, upon reference to which it will be seen that said locking device C consists of a bar formed with a loop or yoke 15 and with projecting fingers 16, the latter being adapted to engage apertures 17 in the webs of the rails. The tie is provided adjacent to the notches or recesses 4 with angle webs 18 con stituting braces or reinforcements which connect the base 1 with the upstanding flange 2. After engaging the fingers 14; with the apertures 17, the yoke 15 may be turned down to engage the flange 2 of the tie, the latter being provided with an aperture 19 for the insertion of a pin or cotter 20 whereby the parts may be secured in assembled relation. It will be readily seen that by this connecting device the rail ends will be held with perfect security against displacement. If desired, the member C may be made of suitable length to engage two or more ties, and said rod or member will then be provided with terminal arms 21 having apertures 22 for the passage of a fastening rod or member.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. It will be seen that I have provided a special tie and rail construction adapted for mutual cooperation and which, when properly as sembled, will absolutely preclude accidental disengagement or disarrangement of the component parts.

Having thus described the invention, what is claimed is:

1. A metallic railroad tie having a web pro ided with rail receiving recesses, each of said recesses extending downwardly and inwardly and having a convexly curved inner wall, a concavely curved outer wall and a fiat bottom, the web of the tie being also provided adjacent to the upper end of the outer wall of each rail receiving recess with a rail head receiving notch.

2. A metallic railroad tie having a web provided with obliquely disposed downwardly and inwardly extending rail receiving recesses, each recess having a convexly curved inner wall, a concavely curved outer wall, a flat bottom portion and an acute angular notch at the angle between the bottom portion and the outer wall; said web being also provided adjacent to the upper end of the outer wall of each rail receiving recess with a rail head engaging notch.

3. A metallic railroad tie having a web provided with obliquely disposed clownwardly and inwardly extending rail receiving recesses, each recess having a convexly curved inner wall, a concavely curved outer wall, a flat bottom portion and an acute angular notch at the angle between the bottom portion and the outer wall, said web being also provided adjacent to the upper end of the outer wall of each rail receiving recess with a rail head engaging notch, in combination with a railroad rail comprising a head, a web, a flange extending from one side of the lower end of the web and a beveled rib constituting a heel portion formed upon the opposite side of the web, and a fas tening key engaging between the rib and the angular bottom notch.

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

TANNES SIVERTSON.
