Specification of Letters Patent.
PatentedDec. 23, 1919.
Application filed July 3,1919. Serial No. 308,414.
To all whom it may concern:
Be it known that I, CALVIN L. Psnnnvs, a citizen of the United States, residing at Mathiston, in the county of Webster, State of Mississippi, have invented certain new and useful Improvements in Railway-Ties;
} and I do hereby declare the f llowing 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 new and useful im rovements in railway ties and particular y to concrete ties.
One object of the present invention is to provide a novel and improved tie of this character wherein the tie is capable of ready and easy flexing movements under the strain of a passing train.
Another object is to provide a novel and improved tie of this character in which the parts can be easily and quickly replaced by new ones, when broken or worn, without disturbing the remainin parts, and without the necessity of replacing the whole tie.
Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.
In the drawing:
Figure 1 is a side elevation of a tie made in accordance with my invention.
Fig. 2 is a top plan view of the tie.
Fig. 3 is a vertical transverse sectional view taken on the line 3-3 of Fi 2.
Fig. dis a bottom plan view 0 the tie.
Fig. 5 is a vertical central longitudinal sectional view through the tie, taken on the line 55 of Fig. 2.
Referring particularly to the accompanying drawing 10 and llfripresent the u per end concrete sections 0 e tie, 12 and 13,
* the lower end sections of the tie, which have their mutually adjacent faces fiat and engaging with the upper and lower Wider faces of the metal bar 14, which extends the entire length of the tie. Between these end'sections are the intermediate shorter sections 15, disposed above the bar 14, and the lower sections 16, disposed below the said bar, each of said shorter sections having a flat face which engages with the one face of the bar.
Disposed longitudinally of the tie, and beneath all'of the lower sections, is a flat metal bar 17 having the elongated longitudinal openings 18. Disposed below each of these openin s is an elongated plate 19 having a vertica ly extending stem 20 slidably disposed in the openin 18. Throughthis stem, and the center of t c said plate, is an opening 21, and disposed vertically through this opening, and through a tie section, is a bolt 22, the upper end, which protrudes a short distance al-ove the upper face of an upper tie section, being provided with a clamping nut and washer 23 and 24:, respectively. The bolts which pass upwardly through the end sections of the tie have the rail gripping clamps 25 thereon and the nuts 23 engage thereon.
The upper and lower sections are thus secured together by the bolts 22, and the sections tied together b the longitudinal bars 14 and 17 so that w en a tram passes over the rails, which. are secured to the ties, the tie will be permitted to flex vertically. The bars 14 and 17 thus securely hold the tie sections in proper relation to each other, while at the same time flexing to permit the sections of the tie to move relatively to each other. There is thus reduced a strong and durable tie, but one w ich is readily flexible whereby danger of breakage is reduced to a minimum, under the great strain due to passin trains.
hat is claimed is:
1. A flexible railway tie comprising a longitudinal series of'sections each composed of upper and lower portions, a flexible element disposed longitudinally of the tie and between the upper and lower portions of the sections, and means securing the sections to the flexible element.
2. A flexible railway tie comprising a longitudinal series of sections each composed of upper and lower portions,'a flexible element disposed longitudinally of the tie and be tween the said upper and lower portions, a similar flexible element disposed below the lower portions of the sections, and means securing the parts together.
3. A flexible railway tie comprisin a plurality of sections disposed in longitudinal alinernent and each composed of upper and lower portions, a flexible metal strip disposed longitudinally of the tie and between said up er and lower portions, a metal strip dispo beneath the lower portions of the till sections, the last-named strip having elongated openings beneeth the several tie sections, bolts dlsposed vertically through the flexible elements and the said sections, and; members carried by the lower ends of the bolts and engaged slidably in the said elongated ogenin s, whereby the bolts are pre vented rom reaking when the strips flex 1 ,eeeeee and the sections move vertically with respect to each other.
In testimony whereof, I affix my signature, in the presence of two witnesses.
