Specification of Letters Patent.

Patented Nov. l 8, i913.

Application niet January 23; 1913. Serial Ito. 743,813.

To ell whom, it 'may concern:

Be it known that I, Jaume Purim Dono van, a citizen of the United States, residing at Georw-n, in the county of Scott and State of Kentucky, have invented certain new 'and useful Improvements in Railroad- Tim; and I do hereby declare the following to-be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.

'lhis invention relates to railroad ties, and it more particularly relates Vto a combination of cement and metal elements united to form e7. pliable railroad tie.

Ain object ,of the invention is to provide a railroad tie of this character, in which the danger of breakage, between the' railway rails, is eliminated.

A still further object is to provide metal railway rail seats permanently united with the concrete elements of the tie.

A still further object is to provide oonnecting bars for the cement or concrete elesaid connecting bars being yieldable.

A still further object is to provide reinforcing elements which also serve to hold said rail seats in position.

A still further object is to provide a rail seat member which may 'be stamped in a single piece from sheety-metal, and at one operation.

@ther objects and advantages will be lhereinafter more clearly set forth in the specilication and pointed out in the claims.

' In the accompanying drawings, which are made a part of this application, Figure 1 is a plan view of one of my im roved ties havingfragmental portions of railway rails seated thereon. Fig. 2 is a. side elevation of the construction shown in Fig. 1. Fig. 3

is a vertical longitudinal section throughY a fragment of one of my improved ties and the rail seat thereof. Fig. 4 is a sectional view on the line 4 4 of Fig. 3. Fig. 5 is a sectional view on the line 5-.5 of Fig. 3. Fig. 6y is a perspective Viewv of my improved rail seat. Fig. 7 is a fragmental detail view of a slightly modied form of my rail seat, and, Fig. 8 is a vertical longitudinal section through a fragment of my improved railway tie, and embodying the modification shown in Fig. 7.

' Referring to the drawings, in which similar reference numerals designate corresponding parts throughout the several views, the

stead of breaking,

two base portions 10, which may be made from cement or from a composition of cement with other suitable materials, are coni nected by a bars 11. These connecting bars are preferably twisted at their through an angle of 90,vasshown, thereby providing a yieldable element between the adjacent ends of the base members, so that the tie Will yield at its middle portion, in-

under excessive Weight and jar-on the rail seats 13 and these bars extend to the bottom of the base portions so as to protect the latter from being broken by the tamping tools when ballastlis being tamped thereunder. The connecting bars are secured to the base portion by means of bolts 14:, which extend through pipe sections 15, which are embedded` in the base portions and extend horizontally therethrough. These pipe sections are preferably dared at their ends 16, thereby being prevented from working or jarring out of the apertures in which they are seated. The base members may sired and proper manner, metal rods or bars 17. A

The rail seat is preferably integral with approximately vertical side flanges 18 and approximately vertical depending tongues 19, which are apertured at 2G for the reoeption of a combined anchoring and rein- :forcing element 21 or 22. This reinforcing member may be formed either as shown in Fig. 3 or as in Fig. 8, and in either event it is placed in engagement with the aperas by means of tures 20, and the cement base is thereafterv molded around the anchoring member, the tongues 19 and the base of the flanges 18, thereby bringing the rail seat on the same plane with the top of the base member and firmly holding said rail seat in fixed relation to the tie. v

The rail seat, flanges and tongues, are preferably formed from heavy sheet metal, as shown in Figs. 6 and 7.v The construction shown in Fig. 6 embodies horizontally extending tongues 23 and vertically extending tongues 24, whereby the rail may be securely fixed upon the seat 12, by bending said tongues inwardl as shown in Figs. 3 and 8. In the modifiedy form shown in Fi 7, I provide down-turned tongues 25, which engage the railanges, for holding the rails upon the seat 18. '4

It is quite obvious that the rail seat,

pair of horizontal connecting be reinforced in any de;`

middle portions 12,l

anges and tongues may be stamped outof a sheet of .metal, at one operation, the several tongues being struck out therefrom; and that it is also quite possible to bend the stamped member into the shape illustrated, without additional manipulation in completing its manufacture.

ln order that the tongues 23 and 24 may be quickly and accurately bent into en gagement with the rail iange, after the latter is seated, vI provide the flanges 18 with apertures 26, for the insertion of any proper tool (not shown) for bracing the flandes against inward or outward movement re ative to the rail, while pressing the tongues 23 and 24 into the positions shown.

It is clearly obvious that the base member is additionally protected against breakage by means of the extended end portions of the connecting bars, being securely bolted at both sides of the rail seats. The portions of the connecting bars 10, which lie directly under the rail seats, are perfectly solid and imperforate, and therefore, the tie has greater strength at the points where greater weight or jar occurs.

Thus it will be seen, from the foregoing, that I have provided a rail tie which is capable of attaining the foregoing objects,

and in a perfectly practical manner.

I do not limit my invention to the exact details of construction, combination and arrangement of parts described and shown, but my invention may only be limited by a reasonable interpretation of the following claims.

lVhat I claim as new is:

1. In a railroad tie, a concrete base member, a rail seat provided with depending apcrtured members and tongues adapted to be bent into contact with a rail flange, and

'anchoring means engaging the apertures,

said depending members and anchoring means being embedded within the concrete base member.

2. In a railroad tie, a concrete base member, a rail seat providing substantially vertical side members, tongues thereon adapted to be bent into contact with a rail flange, apertured members depending i vertically from said side portions, anchoring means engaging the apertures, said anchoring means and depending members being embedded within the concrete base.

3. ln a railroad tie, a concrete base member, a rail seat providing substantially vertical side portions adapted to embrace edges of a rail flange, tongues stamped in said side portion and adapted to be bent inwardly to engage said rail flange, apertured members dependingr vertically from said side portions and integral therewith, and bent rods adapted to engage said apertured members, said members and rods being embedded in the concrete base.

si. ln a railroad tie, a concrete base, a rail seat having ahorizontal bottom embedded in the concrete, substantially vertical side walls integral with said bottom and adapted to embrace the edges of a rail flange, tongues stamped in said` side walls and adapted to be bent from their lower ends to engage said rail flange, apertured members stamped from the bottom between the side walls and depending vertically therefrom, and embedded in the concrete, and rods engaging opposite depending members, the portions of the rods underlying said bottom being bent downwardly and embedded in the concrete, said side walls provided with openings, where- Y by an instrument may be inserted for bracing said side walls while said tongues are being bentv inwardly.

In testimony whereof lhave signed my name to this specification in the presence of two subscribing witnesses.

JAMES PETER DONQVAN.
