Koch, oneonta, N. r. I Application August 18, 1Q47,Serial No. 769,217)

20 Claims. (01. 238-85) 1 The present invention relates to new and useful improvements in railway ties constructed of plastic material such as concrete or the like, to-

'gether with rail fastening means imbedded in the tie.

An important object of the present invention is to provide reinforcing means for the tie integrally formed with the rail fastening means and whereby the reinforcing means is embedded in spaced relation in a tie of electrical insulating -material to anchor the rail fastening means against spreading movement and to prevent a flow of electricity therebetween. Another object of the invention is to provid for a concrete railway tie and in which the rail fastening means and reinforcing means are stamped as an integral unit from sheet metal.

A still further object is to provide a device of this character of simple and practical construction, which is strong and durable, efficient and reliable in use, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and. claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of a tie constructed according to the principles of this invention and showing rails, partially in section, mounted thereon;

Figure 2 is a top plan view of the rail fastening and railway tie reinforcing means separated blank shaped to provide a rail fastener and rein- .forcing member; and

Figure 8 is an enlarged transverse sectional .view taken on a line 8--8 of Figure '7.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of invention, the numeral 5 designates generally one of the metallic rail fasteners and reinforcing members and which comprises a metal stamping and including a 2 rectangular reinforcing strip 6 having one end formed with a laterally projecting head 1 and which is bent along spaced parallel longitudinally extending lines 8 and 9 to provide a downwardly and inwardly inclined flange IU of which the reinforcing-strip 6 is formed as a continuation and coplanar therewith. A relatively narrow flange ll, aseornpared to flange I0, is bent downwardly and inwardlyalong the line 9 and with the central portion of the head I forming aflatplate l2. v

A pair of spaced parallel shoulders l3 are integrally formed with-the head I and extend transversely thereof, the opposed edges of the shoulders being vertical as I shown at l3 and the upper surface'of the shoulders sloping from the vertical edges M as shown at l5. The shoulders l3 provide a channel-shaped seat IS in which the lower flange of a rail I1 is seated.

The shoulders [3 also provide reinforcing means for the flanges l0 and l l.

T-shaped openings [8 are formed in the shoulders 13 at the inner edges thereof for receiving rail fastening bolts l9 and which extend upwardly through rail fastening clips 20 which have one end overlying the lower flange of the rail l1 and are formed at their opposite ends with downwardly extending tongues 2| inserted in the openings l8 to thus hold the bolts from working in the openings or slots l8.

One of the rail fastening plates I2 is provided for each rail I! and with the reinforcing strip or bar 6 of one rail fastener extending parallel to in overlapping relationship and spaced from the reinforcing strip or bar 6-of the other rail fastener and havingits outermost end underlying and spaced from the other plate l2, as shown in Figure 4, to prevent short circuiting of a track signalling system from one rail to the other. In this arrangement the pair of rail fasteners and reinforcing bars or strips are embedded in a concrete railway tie 23 with the reinforcing strips or bars 6 extending longitudinally thereof and with the rail fastening plates 12 positioned adjacent the ends of the tie and flush with the upper surface thereof. Teeth 24 or similar protuberances are struck from the reinforcing strip or bar 6 as well as from the flanges l0 and I l to prevent creeping of the rail fasteners in the tie.

The lower edge of the reinforcing strips or bars 6 are also bent horizontally inwardly to form flanges 25.

A channel iron 26 extends transversely under each rail seat "5 to provide a recess for bolts [9, the heads of the bolts belng inserted through the openings I8 and held against turning in the channel irons, since the lower end of bolt i9 seats under the narrow leg of T-slot I8 and is retained in immovable position by the enlarged lower head within the slot together with clips 20.

Thimbles 21 are recessed in the sides of the tie to receive lifting tongs.

From the foregoing it will be apparent that the reinforcing strips or bars 6 securely anchor the rail fastening plates 12 to the tie and also serve to reinforce substantially the entire length of the tie.

In view of the foregoing description. taken "in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even thoughthere isherei-n shown and described a preferred embodimentof the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention what is claimed as new is:

1. In combination with a railway tie formed from electrical insulating material, a first elongated reinforcing strip embedded in said tie, a first lateral head integral with one end of said strip and overlying said tie at one end thereof, a second elongated reinforcing-strip; embedded in said tie in horizontally spaced parallel relation to said first strip, a "second lateral head integral with one end of said second strip and overlying said tie at the end opposite said first head, thereby "providing electrical insulation for the tie by the spaced relation of the strips in the electrical insulating material, rail holdin'g seats on the lateral heads, and fastening means on said strips and heads to retain them imposition.

2. The combination of claim 1 wherein said fastening means include instruck teeth on said strip to grip the tie and an 'instruck flange depending integrally from said lateral head.

3. A railway tie construction comprising an elongated, substantially 're'ctangularblock' of electrical insulating plastic material, metallic rail supporting plates disposed on the upper face of the block in spaced relation and adjacent the opposite ends thereof, an elongated metallic reinforcing member attached to and depending from each of said plates, said members being embedded in said block and extending longitudinally thereof in parallel, spaced and overlapping relationship to each other, each of saidp'lates and. the reinforcing member attached thereto being electrically insulated from the other plate and its reinforcing member.
