J'GSEPH W. SHIPLEY, OF HYAT'ISVILLE, MARYLAND.

RAILROAD-TIE.

To all whom it may concern:

Be it lgnown that I, Josnrrr \V. SHIILEY, a eitizenlof the United States, residing at Hyattsville, in the county of Prince George and State of Maryland, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a specification, reference being had therein to the accompanying drawing.

This invent-ion relates to railway ties and track fastenings therefor, and the principal objects of the same are to provide a reinforced plastic tie that is'l'ormed of material that will quickly harden and is shaped so that it will have a firm engagement with the roadbed without danger of sinking therein; to provide novel means that will prevent the ties creeping; and to provide novel track fastening means that will normally retain the ails in rigid relation to the tie but which can be readily released when necessary to permit remo 'al. of the rails.

In carrying out the objects of the invention gene ally stated above, it will be under stood, of course, that the essential features of the same are necessarily susceptible of changes in details and structuralarrangements, preferred and practical embodiments of which are shown in the accompanying drawings, wherein 2- Figure 1 is a top plan view of the improved tie and track fasteners, shown in use. Fig. 2 is avertical longitudinal sectional D is a detail perspective view of the base plate of the tie. Fig. 4. is a similar view of one of the rail seats. Fig. 5 is a perspective view of one of the rail clamps. l ig. 6 is a transverse vertical sectional view showing a modified type of rail clamp. Fig. 7 is a detail. inverted perspective view of the clamp shown in Fig. 6.

Referring to the accompanying, drawings by numerals, it will be seen that the improved t'ie comprises a plastic body 8 that is preferably formed of a mixture of crushed stone, sand and cement which in the process of molding has the arched tie rods 9 longitudinally embedded therein in crossing relation, said rods being transversely corrugated so that they will have a firm engagement with said bcjly.

The bars 9 are formed of elongated flat material, the corrugations of which extend transversely and said bars are arched at their centers. Tlhe said bars extend Substan- Specification of LettersPfltent- I Patented Sept. 26, lull. Application filed December 9, 1910.

tially the entire longitudinal length of the ties, and are arranged so that ends of adjacent bars diverge and the center;-; thereof project in oppositedirections. For example in Fig. .2, two of the bars are shown. one bar having; its ends at the upper portion of the ends of the tie and its arched center at the center of the bottom portion of the tie. The other bar has its ends at the lower portion of the ends of the tie, and, its arched center at the upper portion of the center of the tie. This arrangement of bars reinforces the body at all portions.

l lxternallv the sides and ends of'the tie a re provided with the upper and lower beveled surfaces 10 which impart an ormmiental appearance to the tie and also provide the outwardly projecting portions which tend to prevent the ties unduly sinking in the roads bed. The base of the tie is provided with a longitudinal recess 11 in which a flat-plate...

12 is seated, said plate havirur its ends pro vided with spaced bolt openings 13 and its central portion provided witlra longitudinally extending depending flat wing 1-1 that decreases in size from its central portion and its ends merge into the bottom of plate 12. Said wing 14 projects well below the bottom or base of the tie and enters the roadbed so tha't it will prevent the tie creeping.

The top surface of the tie is provided with longitudinal recesses 15 adjacent each end which are intersected by the transverse grooves 16 which extend entirely across the top surface of the tie. Supporting plates 17 are snugly titled in recesses 15 and provided with centrally depressed portions which snugly lit the grooves 16 and form seats 18 ill/Which the base flanges ot' the rails are seated. The supporting plates 17 have openings 20 formed through thenrwhieh are in alinement with the end openings of the base plate and substantially U-shaped bolts 21 are passed through the end openings of plate 12, through the tie, and the end open- 20 ot' the plates 17.

Clamping plates 92 are detachably fastened to the plates 17 by means of the bolts 91 which. pass through central openings 23 of said plates 17 and the lock nuts Said clamping plates 22, as shown in l igs. 1, 2 and 3, are rectangular in shape and have their ends rounded and downturned to provide the pendent flanges 25 which rest on the plates 17 and the pendenttlanges i? which are beveled to conform to and rest on the top surfaces of the flanges of the rails 19. i

It will be clear from theforegoing that by tightening the nuts 24, the plates 22 will firmly clamp the rails 19 to the tie, and that by releasing said nuts, said rails can be readily removed. It will also be seen that the described shape of the tie will permit the same to bepartly embedded in the roadbed without danger of the same sinking farther, and that the arched corrugated rods or. bars add great strength to the tie.

Another distinctive feature of the invention is in the employment of the base plates 12 equipped with the wing 14 by means of which simple means are provided for preventing the tie creeping and at the same time providing abearing plate for the bolts 21.

In Figs- 6 and 7, a modification of the clamping plate is suggested in which the clamping! plates are in the formof cup shaped disks 27 having central openings 28 through which the bolts 21 pass. The pendent annular flanges 29 of said disks rest on theplates 17 and have the beveled lips 30 that engage the base flanges of the rails 19. With the exception of the clamps, this .form of the invention is the same as that and.

' What I claim as my invention is 1 .-A tie formed. of plastic material having the outer surfaces of its ends and sides providedvwith upper and lower beveled portions arranged to provide an outstanding centrally located surrounding projection to revent the tie unduly sinking in the roadd, reinforcing means embedded in said tie, and rail fastening means carried by said t e.

a J 2. A plastic tie having a centrally located longitudinally extending base recess, the

upper surface of said tie provided with longitudinal recesses adjacent each end and transverse grooves that intersect said upper recesses, a base plate seated in the base "recess and provided'with roadbed engaging means, supporting plates seated in the upper recesses and having central rail seats rail clamps restbolts extending ing on said upper plates,

upper plates and through the base plate, tie,

-clamps, and nuts engaging vsaid bolts for locking said clamps in rail-engaging positions.

3. A plastlc tie havmg a base recess and an upper recess adjacent each end, said' upper recesses being intersected by transversegrooves, supporting plates seated in said upper recesses and having rail seats that lie in said grooves, anti-creeping means seated in sald base recess, bolts for rigidly connecting said anti -creeping means and supporting plates, rail clamps carried by said bolt, and lock nuts for adjusting said clamps.
