Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed March 17,1906. $61 lftl No. 306,652.

To all whom it may concern:

Be it known that I, OsMUND O. FORE, a citizen of the United States, residing at Henriette, in the county of Pine and State of Minnesota, have invented certain new and useful Improvements in Railroad-Ties; 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 and use the same.

This invention relates to railroads, and more particularly to ties, and has for its object to provide a manufactured tie embodying a novel arrangement of parts which will permit of downward movement of the ends of the tie, thus preventing fracture of the tie at its center, it being understood that the term manufactured tie is used to denote those formed of metal or plastered substances and to distinguish these from the wooden ties of general use.

It has been found that a principal difficulty with plastic and metallic ties is that after they have been in use for a greater or lesser length of time the downward stress placed upon the ends of the ties, through passage of rolling-stock over the rails, causes bending or fracture of the ties at their centers, and, as stated above, it is the principal object of the present invention to avoid such injury to'the ties.

Other objects and advantages will be apparent from the following description.

In the drawings forming a portion of this specification, and in which like characters of reference indicate similar parts in the several views, Figure 1 is a transverse section of a railroad-track, the present tie being shown in side elevation. Fig. 2 is a top plan view of the tie. Fig. 3 is a section through the connecting-rods on line 3 3 of Fig. 2, showing the inner end of one of the members. Fig. 4 is an elevational view of a modified form of the invention. Fig. 5 is a top plan view of Fig. 4. Fig. 6 is a longitudinal section on line 6 6 of Fig. 5, taken through one of the members.

Referring now to the drawings, there is shown in Fig. 1 a railway-tie including two solid metallic rail supporting members 7, having rail-receiving plates 8 disposed thereupon, and rails 9 are secured upon the plates by means of suitable rail-fasteners 10. A metallic bar 11 is passed longitudinally beneath each member 7 and is bent to extend upwardly over the ends of its member. The members 7 are disposed in alinement with each other, as will be readily understood, and are spaced from each other, as shown. The outer end portions of the bar 11 are turned toextend inwardly over the upper surfaces of the members, as shown at 11, while the inner end portions of the bars, which extend upwardly over the inner ends of the members, as shown at 12, terminate at the upper surfaces of the members in eyes 13, and these portions 12 of the bar have eyes 14, which lie just above the bottoms of the members.

The plates 8 extend longitudinally of the members 7 and have upwardly-extending flanges 15 at their ends, these flanges being provided with perforations 15. The extremities of the portions 11 of the bar 11 are passed through the perforations of the outer flanges 15 of the plates 8 and are threaded for the reception of nuts 16, which lie inwardly of the flanges.

A rod 17 is engaged through the eyes 13 and is passed at its ends through the perforations 15 of the inner flanges 15, this rod 17 being threaded at its ends for the reception of a nut 18 at each end, these nuts lying against the surfaces of the inner flanges 15, which are directed toward the outer flanges.

A pair of crossed brace-rods 19 are provided, and these rods have their lower ends 19 reduced for engagement in the eyes 14,

the upper ends of the rods being bifurcated and flattened and having their resultant spaced fingers engaged with. the portions 12 of the bars 11 just below the eyes 13.

It will thus be seen that through the natural resilience of the rods 17 and 19 the members 7 may be moved vertically with respect to each other to a certain extent, and it will also be apparent that the nuts 16 and 18 may be operated to tighten the rod 17 or to move the plates 8 upon the members.

In Fig. 4 of the drawings there is shown a form of the invention comprising two hollow metallic members A, which are disposed in spaced relation and in alinement with each other, these members being rectangular in cross-section and corresponding to the members 7. At their inner ends the members A have upwardly-extending flanges B, provided with openings B, and means C is provided for securing rails upon the members A. A connecting-rod D, having threaded end portions E, is disposed with its end portions engaged through the openings B, and nuts F are engaged with the threads beyond the flanges.

Brace-rods G are provided, each having a head H at one end connected with the remainder of the red by means of a reduced shank 1, these heads being flattened to extend oppositely beyond the shank, and the heads are engaged through openings K,'

the rod D outwardly of the flanges and re ceive the nuts F thereagainst, it being und erstood that the rods G are each disposed with its head H engaged through the openingK of one member and with its fingers L engaged over the flange of the other member.

It will be seen that in this form, as well as in the first-described form, independent vertical movement of the members is permitted, and the nuts F may be operated to tighten the rod D.

What is claimed is 1. A railroad-tie comprising two alining spaced members, a resilient bar connected at an end with each member, means for moving said bar with respect to the members, and 1(grossed brace-rods located between the memers.

2. A railroad-tie comprising spaced alining members, rail-receiving plates disposed upon the members and having flanges provided with openings, a bar extending longitudinally beneath each member, said bars having their outer end portions turned upwardly and inwardly over the ends of the members and engaged through the opening of one flange of each plate, nuts engaged with the ends of said. bars inwardly of the flanges for operation to move the flanges upon the bars, said bars having their inner end portions turned upwardly over the inner ends of the members and having vertically-spaced eyes in said portions, a rod passed through the upper eyes of the inner end portions of the bars and engaged through the openings of the other flanges of the plates, said rod being threaded beyond the flanges, nuts engaged with the threaded portions of the rod, and crossed brace-rods having bifurcated upper ends engaged with the inner portions of the bars below their upper eyes, said brace-rods being engaged at their lower ends in the lower eyes of the bars.

3. A railroad-tie comprising spaced railsupporting members, a resilient connectingrod for the members, means for varying the tension of said rod, and brace-rods located between the members.

4. A railroad-tie comprising spaced railsupporting members, rail-receiving plates disposed upon said members, bars engaged around said members longitudinally thereof,

a rod slidably engaged with said bars and eX- tending between the members, said rod being adjustably connected with the plates, one at each end, said bars being adjustably connected with the plates at the opposite extremities of said plates from the rod, and brace-rods located between the members.

In testimony whereof I affix my signature in presence of two witnesses.
