Specification of Letters Patent.

Patented Oct. 3, 1911.

To all whom tt may concern:

Be it known that I, J oHN D. KNEEDLER, a citizen of the United States, residing at SiouX City, in the county of WVoodbury and State of Iowa, have invented certain new and useful Improvements in Road- Bed Equipments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to new and useful improvements in road bed equipments, and my object is to provide a two-part tie and connect the parts together by a link.

A further object is to construct the parts of the tie of plastic material and suitably reinforce the same.

A further object is to provide a cavity in the lower portion of the tie sections to receive the soil, etc., forming the road bed.

A further object is to provide a suitable combination support and brace for the rails.

A further object is to provide means for holding a section of wood embedded in the tie to receive the usual form of securing spike, and, a further object is to provide guards for certain parts of the tie to prevent disintegration thereof.

Other objects and advantages will be hereinafter set forth and pointed out in the specification.

In the accompanying drawings, which are made a part of this application, Figure 1 is a perspective view of a portion of the trackway, showing the connecting links between the sections omitted. Fig. 2 is a perspective view of one of the ties, showing two different forms of anchoring means for the rails. Fig. 8 is a bottom plan view thereof. Fig. 4 is a detail sectional view through the meeting ends of the tie sections. Fig. 5 is a perspective view of one of the guard plates at the meeting ends of the sections. Fig. 6 is an enlarged sectional view as seen on line 0-6, Fig. 4. Fig. 7 is a transverse vertical sectional view on an enlarged scale through one of the tie sections. Fig. 8 is a longitudinal vertical sectional view through one of the tie sections; Fig. 9 is a perspective view of one of the tubes employed for holding the anchoring means for the spikes, and, Fig. 10 is a bottom plan view thereof.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates the rails, which are of the usual form and 2 indicates the ties, which ties are preferably formed in two sections 3 and 4, which are Constructed of any suitable plastic material. The sections 3 and 4 are spaced apart at their meeting ends and provided with slots 5 and 6, respectively, to receive a link 7, said link being of less Width and length than the slots so as to loosely fit therein. Extending transversely through the walls of the sections and on opposite sides of theI slots therein, are metal tubes 8, through which project bolts 9, said bolts passing through the ends of the link 7 and forming pivots therefor.

By forming the ties in sections it will be readily seen that they can be very easily handled in applying them to use or removing them from position below the rails and can be more readily handled while Shipping.

It will likewise be seen that by connecting the ends of the sections together with the link, a certain amount of vibrating action will be provided and will allow of a certain amount of depression at the outer ends of the ties and independent of each other.

Collars 10 are placed at opposite Sides of the tie sections, through which the bolt 9 extends, one end of the bolt having a head 11 to engage one of the collars while the opposite end of the bolt is threaded to receive a looking nut 12. Each section of the tie is thoroughly reinforced by eXtending longitudinally and transversely therethrough strips of metal 18 and 14, respectively, which strips are embedded in the plastic material so that no portions thereof will be exposed to the inclemency of the Weather and said strips are preferably twisted to increase the rigidity thereof.

The bottom portion of .each section is provided with a cavity 15, so that when the sections are placed in position on the road bed the weight of the trains passing thereover will cause the earth, or other Composition forming the road bed, to enter the cavity, thus forming an anchoring means for the ties to hold them against endwise movement.

To prevent disintegration of the meeting ends of the tie sections, L-shaped guard plates 16 are provided at the meeting ends of the sections, the horizontal portions of the guard plates entering the slots 5 and 6, while the vertical portions thereof project downwardly along the ends of the sections and although one of the sections may move sufliciently to bring the link into engagement with the bottom of the slot, the guard plate will guard the plastic material of which the tie is formed from becoming injured or broken.

The rails are held in position on the tie sections by providing each section with a recess 17, in which is seated a plate 18, one end of the plate having arms 19 integral therewith which extend inwardly and' over the base of the rail, the inner ends of the arms terminating in verticalstems 20, which rest against the web of the rail and have their upper ends in engagement with the lower face of the head of the rail, said arms holding the rails against spreading. Each plate 18 is provided with openings 21, through which the usual form of spikes 22 are introduced to secure the rails in position on the tie section.

To provide a suitable anchorage for the spikes, the tie sections have tubular sockets 23 embedded therein, the lower ends of the sockets being flattened to form tongues 24, which when embedded in the plastic material will securely hold the sockets against longitudinal movement. lVithin the sockets are placed plugs 25, preferably of wood, said plugs being entered in the sockets under pressure, so as to securely hold the same in position. The sockets and plugs are located in such position as to be immediately below the openings 21 when the plates are properly seated in the recesses and by increasing the size of the sockets and plugs over that of the spikes, any slight variation of the position of the openings in the plates will be compensated for. The walls of the fiattened portion of the socket 23 are left slightly spacedl apart to form an Opening 26, so that should the head of the Spike be broken off, the stem thereof may be driven downwardly through the plug` and into the Opening below the socket, so that the broken spike will not interfere with the new spike when driven into position. It will also be seen that by flattening the lower portion of the socket, the plugs will be prevented from passing downwardly through the sockets.

In order to guard against the pounding of the locomotives when passing over the ties causing disintegration of the' plastic materlal, a metallic cushion 28 1s placed in the recess 17 below the plate 18, said cush-Al with the plates 18, or may be used entirely on straight sections of'trackways. In this.

form of plate the arms are dispensed with and a shoulder 80 provided, against which the base of the rails rest, the plate 29 also having openings 31 `for the' reception of spikes.

The prime object of this invention is to provide more or less elasticity for the trackway and at the same time maintain the:

same in perfect alinement, whichV is accomplished by forming the ties in sections and, in a manner, hingedly securing the same together. i

By using the link it will be readily seen that the rail at one side of the trackway will readily adjust itself without affecting the rail at the opposite side of the trackway, and, although I have shown a preferred form of securing the tie sections together, it will readily be understood that any suitable device for this purpose may be employed. Y

`What I claim is:

In a road bed equipment, the combination with track rails, of plastic ties formedA in two sections, means tofyieldingly con-- nect the sections together and in spaced relation, fa'stening devices for securing said rails to the sections comprising an anchor embedded in each of said sections consisting of tubular sockets having lower, ,oppositely' arranged flaring ends to form tongues having inclined Sides, plugs confinedA within said sockets, and spikes adapted to be driven in said plugs for securing the rails in position.

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