TRACK STRUCTURE.

Application led December 2, 1911.

To all whom t may concern.'

Be it known that we, lVnmmM H. 'Wr-mniAN and CHARLES T. MAXON, citizens of the United States, residing at Curtis Bay, South Baltimore, in the county of Anne Arundel and State of Maryland, have invented new and useful lfmprovements in Track Structures, of which the following is a specification. u

This invention relates to track structures, and has for an object to provide means wherein the rails of the track will be positively heldV against spreading.

Another object of the invention is to provide a track structure wherein the rails will be effectively held against pulling away from the ties.

A still further object of the invention is to provide means whereby the rails of the track can be adjusted relatively to insure accuracy in their association throughout the length of the track.

In the drawing, forming a portion of this specification and in which like numerals lof reference indicate similar' parts in the several viewsz-Figure 1 is a perspective view of a track structure constructed in accordance with our invention. Fig. 2 is a sec-- tion on line 2 2 of Fig. 1. Fig. 3 is asection on line 3 3 of Fig. 1.

The improvement is designed for use in connection with ordinary wooden ties, which are indicated by the numerals 1.

The numerals 2 designate flat metallic wear-plates which are of a substantially rectangular formation and which are of a lesser width and length than the ties 1 upon which they are adapted to be arranged.

As is well known in track construction, the wooden ties are hastily laid and are not at all times arranged at a perfect right angle to the rails which they support, the width of the tie being sufiicient to insure the proper spiking of the rails upon the tie regardless of the fact that the said tie is not arranged at the proper right angle to the rails. With our device, however, it is essential 'that the plates 2 be laid at a direct right angle to the rails, in order that the chairs (hereinafter described) may properly engage with the opposite sides of the rails. We therefore provide each of the plates 2 with a central opening for the reception of a securing element, whereby the plate is medially connected with the tie, and

perfect right angle to the rails, the said plate may be swung or rotated upon its pivot from either of its ends to arrange the plate at a perfect right angle to the rails. The rails rest upon the plates 2, and the said plates each have their longitudinal edges beveled from its top inwardly toward its bottom, and thus the ties 1, when the plates 2 are arranged thereon, are each provided with what may be termed a dove-tailed metallic projection.

In conjunction with the plates 2 we employ chair members et which are arranged for slidable movement upon the plates, as will hereinafter be more fully described. These chairs include the inner members 5 and the outer plates G. rThe outer members are provided with horizontal bottom flanges 7 and the flanges 8. The flanges S extend over the base flanges of the rails and their upper longitudinal surfaces are located directly beneath the ball of the rails. The inner members of each of the chairs are provided with the base flanges S) and the flanges 10. The flanges 9 are arranged in the same general plane with the lianges 7 and said flanges 7 and 9 are disposed beneath the rails, as clearly shown in Fig. 1 of the drawing. The flanges 10 of the inner me1nbers 5 are extended over the inner base flanges of the rails for effective clamping engagement therewith.

From the construction described it will be seen that the chairs of one rail can be adjusted with respect to the chairs of the other rail so that both rails can be accurately positioned relatively throughout the length of the track. rThe members 5 and 6 of the chairs are provided with passages 11 through which the fastening spikes or the like 12 are adapted to be extended and engaged with the ties to hold the chairs in their adjusted positions. It will be further noted by reference to the drawing that the spikes 12 are arranged adjacent the oppo site longitudinal edges of the plates 2, so that said spikes provide means for preventing the swinging movement of the plates 2 upon their pivots. The transverse grooves 13 in the members 5 and 6 of the rail chairs are of dovetail configuration and the walls 14 of these grooves are adapted to underlie the inclined walls 15 of the plates 2, whereby the chairs will be positively held against pulling away from the ties.

The means whereby the companion rails of the track can be adjusted relatively comprises spikes or fastening devices 1G which extend vertically from the plates 2, being 'preferably located adjacent to the ends of the plates. These spikes have revolubly mounted t-hereon flat, rectangular or square members 17 any of the vertical sides 18 of which may be singly presented against the outer members 6 on the rail chairs. The edges or sides 18 of the members 17 are disposed in unequal distances from the spikes so that four different adjustments of the rails can be readily effected. The spikes 16 are of a sufficient length to extend through openings in the plates 2, provided for their reception, as well as to enter the ties 1 so that the said spikes serve as additional means for effectively securing the plates upon the ties.

A joint element is employed for connecting the rail sections together, and as shown, this element includes the outer chair member 19 and the inner chair member 20. These chair members are provided with the alining base flanges 21 which are disposed beneath the base portions of the rails. The inner chair member 20 is provided with a vertical flange 22 which bears against the webs of the rail ends upon the inner sides of the rails. The chair member 19 is provided with a vertical flange 23 which extends upwardly against the webs of the rail ends upon the outer sides thereof. The flanges 22 and 23 are provided with alining passages 24. These passages may be brought into registration with similar passages 25 in the rail ends. Bolts 26 are passed through the passages 24 and 25 for securely holding the rail ends operatively connected with each other. The members 19 and 20 which comprises the joint 6 may be secured to the tie by the fastening spikes or the like 26. The

members 19 and 2O are formed with transverse grooves 27 to receive the dovetailed plate 2 of the tie on which the chair is mounted.

W'e claim:

1. In a device for the purpose set forth, the combination with a wooden tie, of a metallic plate centrally pivotallyjconnected with the tie and adapted to providea bearing sur face for the rails,rail chairs adjustably associated With the plate, means for securing the chairs upon the plate and against movement with relation to the plate, and said means adapted to be arranged adjacent the longitudinal edges of the plate to prevent the swinging movement of the plate upon its pivot.

2. In a device for the purpose set forth, the combination with a wooden tie, of a metallic wear plate upon the tie providing a bearing surface for the rails, said plate being pivotally connected to the tie to permit of the swinging of the plate upon the tie, rail chairs associated with the plate and longitudinally adjustable thereon, means cooperating with the longitudinal edges of the plate and engaging with the tie for retaining the chairs in an adjusted position upon the rail and plate, a rectangular fastening member adapted to abut with the outer faces of the rail chairs, said member having an eccentrically arranged opening to provide four separate abutting edges for the chair, and a spike passing through the opening and the plate to within the tie.

In testimony whereof we affix our signatures in presence of two witnesses.
