REVERSIBLE RAILROAD-TIE.

Specification of Letters Patent.

Application filed February 17, 1917. Serial No. 149,351.

To all whom it may concern: I

Be it known that I, HOWARD HARsH, a citizen of the United States, residing at Osakis, in the county of Douglas and State of lllinnes'ota, have invented certain new and useful Improvements in Reversible Raillowing 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 and use the same.

This invention relates to railroad ties and Y more'particularly to a reversible cement tie.

The principal object of the invention is to provide a railroad tie of this character which consists of a pair of tie sections that are secured together, cushioning means being positioned between the sections so as to allow the tie sections a certain amount of elasticity and which will function the same as the wooden tie.

A further object of the invention is to provide each tie section with removable railholding devices whereby when the tie sections have been reversed bottom for top, the rail-holding devices may be again secured in position to clamp the rails in position.

A still further object of the invention is to provide each tie section with rail-securing devices which may be adjusted to accommodate rail flanges of various widths, and which may be adjusted vertically in these adjusted positions to permit of the rails being shimined up.

With'these and other objects in view as will appear as the description proceeds, the invention comprises various novel features or construction, combination and arrangement of parts, as will be more fully described hereinafter and set forth with particularity in the appended claims.

Referring to the drawings,

Figure 1 is a side elevation of my novel construction of reversible railroad, tie.

Fig. 2 is a vertical transverse sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2.

Fig. 4; is a fragmentary vertical sectional view taken through the adjacent ends of the tie sections.

Fig. 5 is a vertical sectional view taken on the line 5-5 of Fig. 2.

Fig. 6 is a vertical sectional view through one of the spike holder casings.

Fig. 7 is a fragmentary sectional plan view taken on the line 77 of Fig. 3, and

Fig. 8 is a similar view showing the spike holder adjusted to accommodate a rail flange of larger width.

Similar characters of reference are used to denote like parts throughout the accompanying drawings and the following description.

Referring more particularly to the drawings, the reference numeral 1 indicates a pair of tie sections comprising my novel construction of reversible railroad tie, and while I prefer to have this tie constructed of cement, it is to beunderstood that it may be constructed of any other material found desirable and best suited for the purpose. These tie sections are adapted to be secured together through the medium of spaced tie rods 2 that extend entirely through each of said sections and have their outer ends provided with retaining nuts 3 and lock washers 4 so as to securely hold said sections together. These tie rods pass through pipe casings 5 arranged within each tie section which are provided at'their op posite ends with flanges 6, these pipe casings being roughened on their-outer surfaces so as to prevent them from slipping, and if desired may be of non-circular contour in cross section.

I The adjacent ends of the tie sections are each provided with a pair of metallic sockets 7 that are arranged one above the other and designed to alternately receive a cushioning spring 8, said sockets being each provided with circumferential flanges 9 seated within the opposed faces of the tie sections.

The cushioning spring is designed to be normally arranged. in the lowcnpair of sockets and positioned between the adjacent ends of the tie sections is a wedge member 10. This wedge 10 is arranged at the top portion of the tie sections and is designed to be securely held in place by the upper pair of tie rods passingthrough its opposite ends. When the wedge is arranged in this position it will serve to hold and maintain the tie sections 1 in substantially rigid longitudinal alinement and prevent sagging of their inner adjacent ends and yet permit of a slight vertical vibratory movement of them due to the stress and the concussions imparted thereto by the passage of heavy trains thereover. By this construction and tioned within the gagement therewith.

the cushion spring, it Will be obvious that the tie sections will possess a certain amount of elasticity or that equivalent to that of the usual construction of wooden ties.

When the tie is reversed bottom for top, the cushioning spring and the wedge are also reversed so as to occupy the same relative position as shown.

Each tie section is provided adjacent its outer ends with a pair of elongated spikeholding devices 11, each of which, as shown in Figs. 7 and 8, is oblong in cross section and has one of its longitudinal sides open so as to accommodate a latch member 12 that is pivotally mounted at its lower end, as .indicated by the numeral 13, the upper end being provided with a set-screw 14.

Each of these latch members is further provided intermediate its ends with a shoulder 15 disposed on'its outer side and which is designed to lockingly engage within the recess 16 formed intermediate the ends of a casing 17, by off-setting or bulging the Walls of the casing outwardly. recess 16 extends around three sides of the casing, whereby the spike holders may be adjusted around and arranged in three different positions within the casing.

WVhen it is desired to secure the rails 18 in position upon the tie, the spike holdersare inserted within the respective casings and the shoulders 15 engagewithin the recesses thereof, whereby the usual spikes 19 may be driven down within the spike holders between the latch members 12 and the inner wall of the spike holder until the read of each spike rests firmly upon the base flange of each rail. As soon as each spike has been driven home, the set-screws 14 may be turned up so as to lock the spikes in position and against accidental displacement or from working loose.

If it is desired to adjust the spike holders to accommodate a rail having a base flange of a larger width, it is simply necessary to arrange the spike holders in the position shown in Fig. 8, from which it willbe obvious that by reason of the spike holder being oblong and the casing square, that the distance from the center of the rail to the shank of the spike will have been slightly increased or a sufficient amount to accommodate this base flange of larger width. By providing the casing 17 with a recess extending around three sides thereof, the spike holder may be adjusted horizontally in either direction and again posicasing and in locking en- It is also to be noted that by the particular construction of spike holder shown, the rails may be shimmed up and the spikes ad- As shown, this intense j usted vertically and subsequently locked in position by the set-screws 14 to hold the rall in adjusted position.

It will also be noted that since the recesses 16 are formed intermediate the ends of the casings 1(, that when the tie has been reversed top for bottom, the spike holders can also be reversed and inserted from the the meeting ends of said sections and positioned adjacent the top portion thereof, cushioning means arranged between the meeting ends of said sections and positioned adjacent the bottom portions thereof, and means for securing a pair of rails in position upon said tie.

3. A reversible railroad tie comprising a pair oftie sections, means for connecting said sections together, a wedge removably positioned between the tie sections, cushioning means removably positioned between the meeting ends of the tie sections, and railsecuring devices removably positioned within each tie section, whereby the tie sections may be reversed top for bottom.

4. A reversible railroad tie comprising a pair of tie sections having a pair of alining sockets in their opposed ends adjacent the bottom ortions thereof, spacing means arranged etween the meeting ends of said sections and positioned adjacent the top thereof, a cushion spring arranged in said alining sockets, and means for securing said tie sections together.

5. A reversible railroad tie comprising a pair of tie sections having a pair of alinin'g sockets adjacent the top and bottom portions of said sections, removable spacing means arranged between the meeting ends and adjacent the top of said sections, a cushion spring removably arranged in the lower pair of alining sockets, and means for securing said tie sections together.

In testimony whereof I have signed my name to thisspecification in the presence of two subscribing Witnesses.

HOWARD HARSH.
