RAILROAD-TIE.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed April 15, 1905. Serial No. 255,760.

T 0 all whom t may concern:

Be it known that I, REsToEE B. LAMB, a citizen of the United States, residing at Mount Holly, in the county of Burlington,

' plication and removal of bolts, which serve to retain cheek-pieces in position on the rail, while also being adapted to prevent any shifting of said bolts.

It also consists in providing the tie with fastenings vof metallic'plates of different degrees of thickness, the upper one of which is rigid and directly supports the rail, while the underneath rail possesses certain degreesv of resiliency which is desirable in railroad-ties.

Figure l represents a top view of a railroadtie embodying my invention. Fig. 2 represents a longitudinal section of the tie on line zzz, Fig. l, including the ends of rails and the adjacent portions of the fastening devices employed. Fig. 3 represents a perspective view thereof. Fig. 4 represents a section of a portion on line y y, Fig. 1.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a railroad-tie which is constructed of a mass of concrete or artificial-stone material molded into the shape of the body of atie'and having embedded therein a lon itudinally-extending bar or strip B, of meta or other rigid material, which serves to brace the tie in longitudinal direction and prevent disintegration thereof. In the tie there are also embedded the vertical bolts O, which pass through the bar B and have their heads D `below in contact with said bar B. On the tie are placed in the longitudinal direction thereof the plates E and F, the plate E resting on the top of the tie A and the plate F being on the top of said plate E. On the plate F are the lugs H of angular shape separated from each other at top, forming longitudinally-extending passages J between them, said lugs being secured to said plate F by pins which are headed on the under side of the plate F and upper sides of said lugs as rivets, thus firmly securing the latter in position, it being noticed that the bottom heads of -said pins have the lower plate E below them, so that said heads are free from contact with the composition tie A, thus preventing any cutting or grinding action of said heads on said tie, as will -be most plainly shown in Fig. 4. By this provision said lower plate E may be made of thinner metal than the upper plate F, and so be capable of yielding to a certain degree, while said upper plate is thick or heavy and primarily receives the load imposed on the rails, forming a firm support for the latter.

K designates cheekpieces whose under sides are channeled, so as to embrace the lugs H, and have their inner portions L embracing the bases of the fish-plate M, it being noticed that the inner lugs H ,occupy recesses in the base of said fish-plate, whereby the latter are interlocked by said inner lugs H, and as said fish-plate is bolted to the rails creeping of the vlatter is prevented.

It will be noticed that the passages J are operi from end to end. This permits of the introduction into said passages of the bolts N, whose heads are in contact with the under side or upper limbs of the lugs H, the Shanks of said bolts passing upwardly through openings in the cheek-pieces K and are engaged at top by the nuts P, which are adapted to tighten against said cheek-pieces, and thus clamp the latter in position over the lugs H and firmly against the fish-plate, thus firmly holding the same and preventing rising or spreading of the same, it being evident that as the cheek-pieces are channeled in their under side the resilient depending flanges or walls Q embrace the cheek-pieces and serve to prevent any possible movement of said cheek-pieces, while the bolts N retain their position in passages J.

It is evident that when the nuts P are unscrewed the cheek-pieces may be removed from the bars N, and the latter are free to be moved through the passages Yat the free end thereof, and so displaced.

It will also be seen that the tieA possesses the advantages hereinbefore stated, besides superior results in supporting the rail by avoiding eXpensiveness and the decaying nature of a wooden tie.

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

1. A railroad-tie having a body formed of .a composition such as artificial stone, a plurality of parallel plates on the top thereof,v rail-clamping devices on the upper plate and fastenings for said devices on said plate, the lower plate being interposed between said fastenings and the top of said tie and being of less thickness than the upper plate.

2. A railroad-tie, a plate thereon, lugs rising therefrom with a longitudinal assage between the same at the top thereo', and a bolt having its head beneath said lugs and its shank freely occupying the passage therein.

3. In a railroad-tie, lugs rising therefrom and separated from each other forming a passage'between the same, a bolt having its head beneath the top of said lugs and its shank occupying said passage and a cheekpiece adapted to engage the base of a rail and be engaged by said bolt.

4. In a railroad-tie, lugs formed of angular members with a passage between the top walls thereof, a bolt having its head below said top wall and its shank occupying said passage and a rail-engaging cheek-piece adapted to embrace said lugs and have said bolt pass therethrough and a tighteneng device on said bolt.

5. In a railroad-tie, lugs rising therefrom, a bolt engaging therewith, a rail-engaging cheek-piece adapted to receive said bolt and.

a device on said bolt adapted to tighten said cheek-piece in position, said cheek-piece hav- `ing walls adapted to embrace said lugs.

6. In a railroad-tie, a lug rising therefrom and a rail and a fish-plate therefor, the base of said fish-plate having a recess therein to receive said lug.
