WILLIAM A. LUCAS, 0F MOOREWOOD, OKLAHOMA.

RAIL-TIE.

Application filed December 22, 1917.

To all whom #may concern.'

Be it known that I, WILLIAM A. LUCAS, a citizen of the United States, residing at Moorewood, in the county of Custer and State of Oklahoma, have invented certain new and useful Improvements in Rail-Ties, of which the following is a specification, reference being had Vto the accompanying drawings.

This invention relates to vrailroad ties and has for its primary object to provide a metallic rail tie having cushioning means for the rails whereby the weight of the locomotive will be yieldingly sustained and undue wear upon the ties or displacement thereof obviated.

It is another important object of my invention to provide a tie of the above character which is so constructed that lateral spreading movement of the rails will be pre- Vented.

The invention has for an additional object to provide a metal tie structure of such form that the tie may be securely anchored upon the road bed and held in place by the crushed rock or other ballasting material.

It is a further general object of my invention, to provide a railroad tie having the above noted advantgeous features, which is exceedingly strong and durable in its construction, light in weight, eiective and reliable in practical use and which can be manufactured at relatively small cost.

Vith the above and other objects in View the invention consists in the improved construction, combination and arrangement of the several parts as will be hereinafter more fully described, subsequently claimed and illustrated in the accompanying drawing in which similar reference characters designate corresponding parts throughout the several views and wherein:

Figure 1 is a side elevation of my improved railroad tie showing the manner of ballasting the tie upon the road bed;

Fig. 2 is a longitudinal sectional view;

Fig. 3 is a top plan View;

Fig. 4 is a bottom plan view; and

Fig. 5 is a section taken on the line 5-5 of Fig. 3.

Referring in detail to the drawing 5 designates the base of the tie, 6 the opposite side walls thereof, 7 the end walls and 8 the top wall. This tie is preferably constructed of cast metal and the several parts thereof may be assembled and secured together by any Specification of Letters Patent.

Serial No. 208,361.

gitudinal inclination in relatively opposite`r directions and substantially in parallel relation to the curved port-ions of the wall 8.

12 designates a pair of spring plates which are secured at one of their ends in any preferred manner to the top side of a rectangular meta-l block 13 which is seated upon the base wall of the tie body between the lower ends of the spaced webs 11. These spring plates l2 are longitudinally curved and extend in opposite directions between the curved top wall section 8 and in close proximity thereto. Each of said springs at its end is bolted or otherwise fixed to a metal plate 14 which is disposed upon the underside of the spring plate 12 and extends across substantially the entire width of the tie. To this plate 14 the upper end of a coil spring l5 is secured, the lower end of said spring being fitted within an annular retaining ange 16 upon the base wall of the tie.

R designates the rail, which is secured upon the end of the spring plate l2 by the clamping bolts indicated at 17. Y

Upon the underside of the base wall 5 of the tie, flanges or ribs 18 are integrally formed and extend along the longitudinal edges of the tie. These flanges are connected at intervals by means of the spaced transverse ribs 19.

As seen in Fig. l1 of the drawing, the ribs 18 and 19 are securely embedded in the road bed and prevent the longitudinal or lateral shifting movement of the tie body. The ballasting material indicated at B covers the central portion of the top wall of the tie filling the depression formed by the curved wall sections 9. Thus it will be manifest that the tie body is securely anchored or held against shifting movement upon the road bed.

The top wall of the tie at the points 'the construction and several advantages of my improved rail road tie will be clearly .and fully understood. 10v

Nlien the locomotive passes over the tie, the weight thereof is yieldingly cushioned by means of the f heavy coil spring l5 and the spring plates l2 so that wear upon vthe tie is reduced 'to a minimum, and displacement of the ballast is obviated. Also it is to be noted that by moiuiting the rails upon the tie in the inanner above described, the rails are held against relative lateral spreading movement, thus obviating the possible wreckage of the train; the several parts of the improved tie are of a relatively simple form, and can be constructed at small cost and readily assembled. The tie as la whole is very durable and relatively light in weight.

' While l have herein shown and described the preferred construction and arrangement vof the several parts employed it is to be invention as claimed.

Having thus fully described my invention what I claim and desire to secure 'by Letters Patent is:

l. ln combination, a hollow metal tie having its top and side walls cut away adjacent its ends to permit of a limited downward movement of the rails, anda pair of spring plates centrally held within the hollow tie and extending longitudinally in relatively opposite directions, the rails being secured upon the respective spring plates.

2. ln combination, a hollow metal tie having its top and side walls cut away adjacent its ends to permit of a limited downward movement of the rails, a pair of spring plates centrally held within the 'hollow tie .and extending longitudinally in relatively mit of the limited vertical movement of the respective rails, a pair of spring plates and a rigid connection between the saine at one y of their ends, means centrally loca ted within the tie body to retain the connecting means therein against shifting movement, said spring plates extending longitudinally of the tie in relatively opposite directions, metal plates secured to the free ends of the spring plates upon which the rails are adapted to be secured, and a coil spring arranged within each end of the tie between the base thereof and one of said metal plates.

el. i hollow metal tie having yielda-ble rail supporting means therein, the top wall of the tie being downwardly and inwardly curved to theeenter of the tieto provide a depression for the reception vof the ballasting material.

5. A railroad tie having its upper surface longitudinally curved inwardly and downwardly from the ends of the tie to its center to provide a depression for the reception of the ballasting material.

ln testimony whereof l hereunto affix my signature in the presence of two witnesses.

VILLKAM A. LUCAS.
