Application led February 18, 19253f Serial No. 537,551.

To all-whom t may concern:

Be it known that I, ADAM L. CRANE, a citizen of the United States, residing at Fort Mill, vin the county of York and State of.

to Yprovide a tie and rail fastener of the pres.

ent character, similar to but different from the construction of tie and rail fastener set forth, claimed and illustrated in the patent to Adam L. Crane, No. 1,373,601.

In this patent cushioning members are used, but which are dovetailed in the tie. In the present invention it is the aim to eliminate `the dovetail construction, and in lieu thereof. simply insert the cushioningl members in recesses ofthe tie.

li`urthermore in said patent the cushioning members are supported upon a plate embedded in the tie, but in the present construction it is the aim to eliminate this plate, and in lieu thereof' utilize reinforcng rods, arranged adjacent the upper surface of the tie and-adiacent the lower surface of the tie. In arranging 'these reinforcing vmembers orrods, it is the aim to upturn ,the ends ofthe lower reinforcing' rods so as vto extend beyond the upper reinforcing rods, thereby giving 'greater strei'igth to the cement structure of tie.

In the aforesaid mentioned patent there is nomeans for pulling thetie in place. In other Words should it' be necessary to repair the road, by entracting a worn tie, and in its stead to insert a new tie, there is no means by which'theftie can be pulled into place under the rails., Hence, in the present invention, itis th'e aim to extend the upper central reinforcing rod beyond the upper ends ofthe tie to form nooks`which have rings by which the tie canrbe pulled into place under rails. The ends of the tie are formed with cavities adjacent the hooks,

to the hooks.

Still: another purpose the provision of upper and lower transversely dlsposed re-k inforcing plates disposed at points centrally betweenthe ends ofthe tie, above and below the upper' and lower reinforcing; rods, in

= combination with perpendicular rods connecting the transverso'plates, to insure rivgidity for the reinforcing means, yet permit of a reasonable amount of elasticity of the tie, while in place.

It :has been found that ties which are flat 'upon their underI surfaces, cause What has been termed as a center-bind. In other Words the ballast of the road adjacent the sides thereof becomes depressed, causing a crowding,` of the ballast near the center of the bed, hence causing the ties to rock.

It is, therefore, the purpose of the present invention to obviate this difficulty by con- Y structing a tie, which is thicker in the center than at the ends, the under .surfacev of the tie tapering from the thicker portion to the ends` of the tie. From practical experience it has been found that this construction of tie will obviate the so called center-bind of the tie,`in other Words Will obviate the crowding or collecting of the ballast near the center of the road bed, and thereby will permit the ties to lie or assume their proper positions, and to such an extent as to permit the rolling stock to travel Without undue rocking; movement.

While the design and construction at pres ent illustrated and set forth are deemed preferable. it is obvious that as a result of a reduction of the inventiontoamore practical form for commercial purposes, the invention may be' susceptible of changes, and the right to these changes is claimed, provided they vare comprehended Within the scope of what is claimed.

The invention comprises furtherv features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

Referring to the' drawings, 1 designates the body of the tie, which may be constructed of any suitable plastic material, such as cement concrete or the like. The upper surface o the tie adjacent lboth ends is provided with recesses 2, for the reception of cushioning members or blocks These cushioning members may be constructed of an' suitable wood, rubber, or fibre of any kin such as will permit rails. Suitable plates 4 engage upon the cushioning members or blocks 3, and are provided with lshaped projections 5, to pierce or extend into the cushioning members, to prevent movement of the plates. These plates support the rails 6. The recesses 2 may be dovetailed, as shown in the aforesaid patent, or otherwise constructed, so long as the` cushioning members or blocks are held in position and under the rails.

Engaged upon the upper surfaces of the plates 4 and overlying the base of the rails are clamping plates 7, which 'are held against rocking movements by means ofthe lugs 3 which rise from the plates 4. Suitable bolts 9 pass upwardly through the tie, through the cushioning members or blocks 3, through the plates [1 and the clamps 7, and are provided with nuts itl on their upper ends, to not only hold the bolts in place, but also secure the clamps in position. Additional bolts 11 pass upwardly through the tie, through the cushioning members or blocks 3, and also through the plates 4. In order to apply the bolts 11, they are inserted downwardly through the plates 4 and through the cushioning members and through the tie. These bolts 11 on their upper ends are provided withl heads 12, laterally extended, to overlie the bases of the rails, in order to coopera-te with the clamping plates 7 for the purpose of holding the rails in position. In order to hold the bolts 9 and 1l in position, plates 13 are positioned adjacent the under surface of the tie. In fact these plates 13 are countersunk in diagonally disposed recesses 14 of the under surface of the tie. These recesses 14 are open at their ends, and as shown in Figure 8 the central portions of these recesses 14 may or may not be closed, in other words filled up. vIf these central protions 14 are closed, the plates 13 may be inserted from either side of the tie, or preferably molded in the tie, when the tie is constructed. The bolts 9 and 11 pass up- Wardly through the tie, and through the plates 13. thereby insuring a secure anchorage for the bolts, sufficiently to not only retain 'the clamps '7, but also the rails 6 in 9 have nuts upon their of a cushioning effect for the em 1 ,eeaeoo on the upper that the plates 13 may be easily renewed, if

necessary, by simplydetaching the nuts 10 and 15, and extracting the bolts, which may permit the plates to be moved transversely of the tie.

Arranged longitudinally of the? tieand bedded in the cement or concrete thereof adjacent the upper surface of the tie are reinforcing rods 16, which at points adjacent' 80 the cushioning members or blocks 3 are made to conform to' the contour of the blocks. Anv number of these rods 16 may be used. However it has been found convenient and practical to use only three. It is obvious that the reinforcing rods 16 may or may not be straight for their full lengths as shown in Figures 3 and 7 clearly. other words Figure 3 illustrates as conforming to the contour of the cushioning members or blocks 3, whereas Figure 7 discloses these reinforcing rods 16 as lbeing straight. In other words in Figure there are no offset parts, such as shown at 17 in l `igure Arranged and embedded in the tie. adjacent the under surface thereof and confdrming thereto are lower longitudinally disposed reinforcing rods 18, the ends of-which are upturned as indica-ted at 19.

The ends of the tie have suitable cavities 20. which' permit rings 21 to be connected. to the hooks 22, which are formed upon the ends of the reinforcing rods 16. It will be noted that the yhooks 22 are countersunk due to the provision of the recesses 20, and it 'willkbe noted that by means of the rings 21 an operators hand may engage therewith` whereby the tie may be pulled into place under the rails. especially when repairing the road. ln other words should it be desired to repair the road by removing an old tie andre-placing it with anew one, of the construction herein illustra-ted, the workman may simply grasp the ring 21, so as to pull the tie transversely of the vroad hed and under the rails. In fact the rings 21 may be used for pulling the `tie into place, even though constructing a new road.

Arran ed transversely of the tie and embedded t ieren at points adjacent the u p and lower surfaces thereof and substantially the ends of the tie are upper and lower metallic bars 23 and 24. The upper bar 23 extends across the upper tie or reinforcing rods, while the lower bar24 extends transversely below means of the metallic is reinforced transversely. and itis also rcinforced longitudinally, due to the fart that the lower rods 18.
