TIE.

T0 all whom it may concern Be it known that I, MINOR ECHAMBER- LAiN, a citizen of theUnited States, residing at the city of Lebanon, county of La. clede, and State of Missouri, have invented a new and useful Tie, of which the following is a. specification.

This invention relates to rail ties, and it has particular reference to ties composed of concrete and provided with metallic reinforcements.

An object of the invention is to provide a monolithic concrete tie having a number of reinforcements embedded therein, each of said reinforcements comprising a metallic sheet folded to provide a number of horiontally disposed wings, two of which are of double thickness and the remaining two of single thickness of the sheet, connections uniting one of the wings of single thickness on one of said reinforcements with one of the wings of single thickness on the other reinforcement, and means for securing the rails to the ties. i

Another object is to provide an improved concrete rail tie comprising a concrete body,

A a number of parallel reinforcements em-v -side elevation of the tie.

bedded in said concrete body and each comprising a metallic Sheet folded to provide a number of wings, atleast one of said wings in each reinforcement being of a double thickness of the sheet and another of said wings of a single thickness of the sheet, and metallic connections uniting the wings of single thickness, in combination with rail supports, means for securing said rail supports to the tie, and mea-ns for securing the rails upon said supports.

Additional object-s of my invention will appear from the following description, reference being madevto the accompanying drawing in which I have illustrated aV suitable embodiment of the invention and in which Figure l is a plan View of two ties having the rails secured thereto. Fig, 2 is a Fig. 3 is a longitudinal vertical sectional view approxi mately on' the line 3 3 of Fig. 1. Fig. 4 a longitudinal horizontal sectional view approximaLelys-` on tlfie line Ll--Ll of Fig. 2. Fig. 5 is a .perspective view of the tie before the rail supports are placed in position in connection with the tie. Fig. Gis an end elevation of a tie.

views, and being a sectional view on the line 7--7 of Fig. 2. Fig. 8 is a 4perspectiveuview the remaining two of which are of a single thickness of the sheet. The wings of double thickness extend in vertical planes within the concrete body, and the wings which are of single thickness extend 1n horizontal planes, so that one of the wings of single.

thickness on one of said reinforcements extends toward one of the wings .of single thickness on the other reinforcements. By arranging the reinforcements so that the wings-of double thickness are in vertical pla-nes within the concrete body it is obvious that said reinforcements will be better enabled to resist the stresses and strains to which the tie is subjected, sincemostof the stresses and s t ains come from above the tie. Each outwardly extending Wing of single thickness is equipped with an auxiliary reinforcement 3 which is formed of sheet metal folded to provide a doubleportion between which the wing of single thickness of the reinforcement 2 is received, and also to provide two vertically extending portions of single thickness which abut against the vertically disposed wings of double thickness of the main reinforcements 2. The reinforcements 3 are preferably secured in connection with the reinforcements 2 by stamping lateral extending tongues 4 from the overlapping portions of said reinforcements.

The reinforcements 2 are parallel,'and

are arranged in substantially the same hori zontal plane. The inwardly extending wing of single thickness on one of said re1nforcements 1s connected with the adjacent wing of single thickness on the other f reinforce.

.reinforcements 2. Thus, the-two longitudiv` nalxreinforcements 2 are united by auxiliary Y reinforcements, so that each reinforcement affords additional strength to the other. The ends of the connections 5 are secured to the lateral wings of the reinforcements 2 by suitable fastening devices 7.

In the upper side of the tie near each end thereof, arecess 8 is formed of suitable size to receive a rail support 9, preferably of wood or other suitable material and of a size sui'licient to support the rails and afford the necessary or desired resiliency. The supports 9 are seated Within' the recess 8, and are above the metallic reinforcements, as will be understood by reference to Figs. 3 and 7. The concrete is provided with two holes 10 below each of the recesses 8, and fastening bolts 11 extend through said holes 10 and through holes in the rail supports 9. A metallic rail seat is supported upon each of the rail supports 9, and includes a plate portion 12 seated upon the support 9 and provided with holes 13 through which the bolts 11 extend. The plate 12 is provided with two depending flanges 14 which engage opposite sides of the rail support 9 and thereby cooperate with the bolts 11 to retain the rail seat inposition on the support. The

rail 16 is seated between two vertical flanges 15 on the rail seat 12, said flanges engaging the opposite edges ofthe base of the rail and thereby preventing lateral movement of the rail upon the seat. The rail is further retained in position by metallic. arms 17 which have holes through which the bolts 11 extend, and which are prevented from displacement from the boltsv by the clamping nuts 18 upon the upper ends of said bolts. Each of the arms 17 is provided with a shoulder 19 bearing against the adjacent flange 15 and thus preventing the clamping arm 17 from being turned fiom its position. The end of each of the arms 17 extends over and bears against the upper surface of the base of the rail, while the inner ends of said clamping arms bear against the vertical sides of the web of the rail, thus coperating with the shoulder 19 and the flanges l5 to prevent the clamping arms from being dislocated.

A tie constructed-in accordance with the foregoing description and illustration is very simple and durable` The reinforcements are wholly embedded within the concrete so that they are not subject to corrosion. The provision of the reinforcements i with the vertically disposed wings of double thickness, the efficiency of which is increased' by the auxiliary reinforcements, provides a tie which will resist all of the ordinary stresses and forces to which the tie will be subjected.

It will be obvious that there may be varioiis alterations and modifications in the construction of the tie and the various parts and elements thereof without departing from the principles and scope of the invention. Therefore, I do not restrict myself to precise features of construction or arrangement, but

What l claim and desire to secure by Letters Patent is:
