RAILROAD TIE AND CUSHION.

Specification of Letters Patent.

Patented Sept. 28, 1909.

Application filed April 24, 1909. -Seria1.No. 491,999.

To all whom it may concern:

B-eit known-that I, EDWARD H. JOHNSTON, residing in and county of Philadelphia, State of have invented a new and useful Railroad Tie and Cushion, of which the following is. a specification.

'My invention consists of a railroad tie and cushion embodying a tie of metal and a cushion of wood, thus combining the advantages of both in the device.

It consists also of novel means for retaining a rail in position on the cushion and tie.

It consists further of novel means for anchoring tlie tie in a road-bed.

For" the purpose of explaining the invention, the: accompanying drawlng illustrates a satisfactory reduction of the same to practice, but the important instrumentalities thereof may be varied, and so itis to be understood that the invention it not limited to the specific arran ement and organization shown and describe Figure 1 represents a side elevation of a railroad tie and cushion embodying my inthe city vention. Fig. 2 represents a longitudinal verticalsection of an end portion on an enlarged scale. Fig. 3 represents a transverse section on line :v.w, Fig. 2. Fig. 4 represents a perspective view of an end portion. Fi 5 represents a bottom plan view of an en portion. Fig. 6 represents a horizontal section on line 3 y, Fig. 3.

Similar letters of reference indicate corresponding parts in the fi ures.

Referring to the draw1ng:A designates a tie formed with a metal body comprising the B and theboxes T centrally channe'led portion C at the ends thereof, said portion being open at the top and said boxes being open in In the boxes are blocks or cushionsD of wood comprising'the direct supports for the rails E, the tops of the boxes being cut away forming channels F to receive the rails and permit them to rest upon the blocks, said to' s bein notched or recessed for the s ikes' (g, whic are driven through the same into the blocks, thus firmly connecting'the rails withthe latter, while the side walls of said. channels F embrace the flanges of therails and prevent spreading thereof, it being evidentthat the blocks -D. 'rovideelastic supports for the rails, 'whi e avoiding the expensiveness of ties made entirely, of wood, and there is dura bilityin the body in that it is formedof .rectly on the cushions and metal. Inorder to set the blocks true in which overhang the adjacent sides of the bases of the rails and serve to prevent rising of the rails when the latter are in use, it being evident that when the spikes are tracted,-the rails may be turned laterally and so withdrawn from under said cheek pieces L.

Depending from the bottom of the tie, are longitudinally and transversely downwardly extending ribs M, N, the transverse ribs N being inclined outwardly in opposite directions at the ends of the tie, the several ribs acting as anchors which enter the roadbed and interlock therewith, and so serve to prevent creeping of the tie in either direction, while also strengthening the base of the.

tie.

Attention is directed to the fact that the tops of the cushions D are above the bases of the channels F, whereby the rails rest'diso are subject to the yielding nature of the latter.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A metallic railroad tie composed of a bodyhavin a box on an end thereof, said box being ormed with longitudinally disposed ribs rising substantially centrally therefrom, the rib on the inner side being extended outwardly forming a cheek piece to overhang the adjacent side of the base of a rail, and a partition rising from the base of the box adjacent the inner terminal of said box.

i"'2 .'A metallic railroad tie composed of a body'havin a box on an end thereof,-said box being formed with longitudinally disposed ribs rising substantially centrally therefrom, the rib on the inner side being extended outwardly'forming a. cheek piece to overhangthe adjacent side of the base of a rail, a partition rising from the base ofthe box adjacentthe inner terminal of said box, and a reinforcing brace for said parti-' tion formed integral with said partition and the bottom of the tie outside of the box.

,3; A metallic railroad tie composed of a I body having a hollow box on each end therebody and a box on an end thereof, said box having in its top a channel, and vertically disposed ribs rising from said top and extending longitudinally of the tie, the inner rib being extended inwardly to engage over 1 the top of the base of a rail, and a partition rising from the base of the box at the inner terminal of the latter, and a brace outside of the box joining said partition and the bottom of the tie.

5. A railroad tie comprising a metallic body and a box on an end thereof, said box having in its top a channel, and vertically disposed ribs rising from said top and extending longitudinally of the tie, the inner rib being extended inwardly to engage over the top of the base of a rail, the bottom of the tie being formed with transverse and longitudinal downwardly extending. ribs, those at the'ends extending outward beyond the plane of the ends of the tie.
