ELMER S. MICHAEL AND CLARENCE G. MICHAEL, CF FORT HILL, PENNSYLVANIA.

RAILWAY-TIE.

Specieaton of Letters Patent.

Patented June 8, 1909.

To all whom it may concern:

Be it known that we,jELMER S. MI- CHAEL and CLARENCE G. MICHAEL, citizens of the United States, residing at Fort Hill, in the county of Somerset, State` of Pennsylvania, have invented certain new and useful Improvements in Railway-Ties; and we 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 railway ties, and more particularly to metal railway ties, and has for its object to improve the construction and produce a tie of this character which will not creep'7 either longitudinally of the track or transversely thereto, and which will not be lifted by the action of the frost, or other force which has a tendency to elevate the tie, and whichwill also be effectually prevented from settling into the roadbed. f

With these and other objects in view the invention consists in certain novel features of construction as hereafter shown and described and then specifically pointed out in the claims, and in the drawings illustrating the preferred embodiment of the invention.

Figure 1 is a side elevation, and-Fig. 2 is a plan view with asection of the rail connected thereto. Fig. 3 is a longitudinal view in section on the line 3 3 of Fig. 1. Fig. 4 is a longitudinal section on the line 4-4 of Fig. 2. Fig. 5 is a transverse section. Fig. 6 is a section on the line 6 6 of Fig. 2. Fig. 7 is an enlarged detail of the rail clamp.- Fig. 8 is a perspective view from beneath of the rail brace.

The improved device comprises a body member formed with spaced sides lOll, ends 12-13, and a bottom 14, the bottom projecting beyond the sides and ends and providing an encompassing flange around all the sides of the body, as shown. Formed in the sides 10-11 intermediate the ends thereof are relatively long depressions 15-16 preferably of flat V-shape, while similar depressions 17-18 are formed in the ends 12--13 the end depressions being preferably with sharper angles than the side depressions.

Formed in the bottom 14 of the body is a longitudinal recess 19, while apertures 20-21, preferably triangular, are formed through the bottom 14. The depressions 15-16 and 17--18 receive `the tamping or movement transversely of the rails, whileA the depressions 17 firmly support the tie from movement longitudinally of the rails or of the roadbed, while the recesses 19 and the apertures 20-21 serve to prevent either lateral or longitudinal movement of the tie, as will be obvious. The flanged portion' of' the bottom 14 bearing beneath the tamping material also serves an important purpose in preventing the tie from being lifted by the action of frost or other like ower, while at the same time the area of t e tie is materially increased and the tendency to be depressed correspondingly decreased.

The top 22 of the tie bears upon the upper edges of the sides 10-11 and the ends 12-13, and is preferably provided with deending flanges 23 which enables the top to e secured firmly to the sides and ends by rivets represented at 24. The top 22 is provided with transverse recesses 25-26 to receive the tie flanges of the rails indicated at 27, the recesses 25-26 being spaced apart to correspond with the gage of the rails or the distance apart between their treads.

Formed through the top 22 adjacent to the recesses v25 are apertures 28, the apertures being preferably square and adapted to receive standards 29 having projecting upper ends 30 to bear over the tie flanges, the standards 29 having longitudinal perforations to receive the clamp bolts 31, the clamp bolts passing through clips 32 bearing beneath the top 22 and likewiseV provided with an aperture to receive the bolts 31, the bolts being secured in place by clamping nuts 33 bearing upon the u per ends of the standards. By this simplel means, it will be obvious that a very strong clamp device is provided for securing the rails to the tie, and which may be tightened in event of their becoming loosened by simply setting up the nuts 33. As many of these clamp devices vmay be employed as required, but generallyV two for each tie will be sufficient, as shown. Formed in the upper face of the top 22,

near one end is a shallow recess 34 having a central aperture leading through the top 22 and iitting in this recess is a projection 35 on a base portion 36 of a curve brace 37, the latter bearing by its free end against the side of the head portion of the rail, and also underneath the same. The members 236-37 are employed only at curves, and u on the outer rails of the curves, which are su jected to a very severe lateral strain, and require to be iirmly braced.

The strains upon the curve members are very largely longitudinally of the tie, and the projecting portionl 35 therefore receives the brunt of these longitudinal strains, and thus relieves the clamp bolt by which the curve brace is connected to the tie from strains. This is an important feature of the invention and adds materially to its utility and elticiency. The tie is preferably formed from cast steel, but may be of pressed steel if preferred.

With the device thus constructed it Will be obvious that a very eillicient, durable and strong tie is produced, which will not be displaced by the impact of the tra'liic passing over the roadbed, as the tie structure is rmly supported from movement in any direction, either laterally or longitudinally of the roadbed, as before described.

- The device may be inexpensively manufactured, and of any required thickness or strength to correspond to the weight of traffic which passes over it.

The tie structure will be about the usual size which is eight feet long over all and about eight or ten inches square transversely,

but these dimensions may be varied, it is obvious, Without affecting the principle of the invention, and it is not therefore desired to limit the invention to any particular dip mensions, or to any particular kind of maf terial.

the tie is tamped, and thus assists in anchoring the tie.

The improved tie may be employed for supporting switches by simply increasing its length, as is common with ordinary Wood ties, and it will be obvious therefore that the improved tie may be employed in any locality Where Wood ties can be used.

What is claimed, is

l A metal railway tie comprising a hollow body, a top detachably connected to the body and with transverse recesses to receive, the base `lianges of the rail, said top having apertures adjacent to said recesses, clamp devices com prising standards extending through said apertures and projecting at one side to bear over the tie llange of the rail, clips extending beneath the top oll the tie, and clamp bolts extending through Isaid stamlards` and the clips and with clamp nuts ban-ing upon the top o'lI the standards.

2. A metal railway tie. comprising a body. a tcp formed upon said body and. provided with transverse recesses to receive the lie flanges olI the rails, and with a cavity near one end., means l'or detachably connecting said top to the body, means lor clamping said rail to said top, and a curve brace comprising a base member having a depression engaging the recess in said top and with a projecting brace bearing against the head ol the adjaM cent rail.

A metal railway tie comprising a hollow body having depressions in the sides and ends, a top detachably connected to the body and with transverse recesses to receive the base 'llanges ol' the rails, said top l'ntving apertures adjacent to said depressions, clamp devices comprising standards extending through said apertures and projecting at one side to bear over the tie flange ol' the rail, clips bearing beneath the top ol' the tie, and clamp bolts extending through said stainlards and the clips and with clamp nuts bearing upon the top oll the standards.

'-1. A metal railway tie con'lprising a hollow body having dejnessions in the sides and ends to receive the tamping material, a top formed upon said body and provided with transverse recesses to receive the tie llangcs ol' the rails, and with a cavity near one end, means for detachably connecting said top to the body, means for clamping said rail to said top, andv a curve brace comprising a base member having a depression engaging the recess in said top and with a projecting brace bearing against the head of the adjacent rail.

In testinlony whereof, we alliX our signatures, in presence ol' two witnesses.
