GEORGE I1. WOOD, OF DENVER, COLORADO.

RAILROAD-TIE.

Specification of Letters Patent.

Patented Oct. 29, 1918.

Application filed September 25, 1917. Serial No. 193,063.

To all whom it may concern:

Be it known that I GEORGE L. Wool), a citizen of the United tates, and a resident of the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a full, clear, and ex act description, such as will enable others skilled in the art to which the invention appertains to make and use the same.

y invention relates to improvements in railroad ties, and the invention has for its object the provision of a metal tie which embodies the cushioning efiect of the commonly used wooden tie;

A further object of the invention is to provide a metal railroad tieby means of which the rails may be securely locked thereto without the'use of rail spikes.

l/Vith these and other objects in view, the invention will be described in detail with reference to the accompanying drawing.

I11 this drawing, Figure 1 is a plan view of the railroad tie; Fig. 2 is a side elevation view thereof; Fig. 3 is a detail view of one end of the tie, showing the locking lip thereof; and Fig. 4 is a cross sectional view taken on the line H of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

Let the numeral 5 designate the central portion of the metal railroad tie, and the numerals 6 and 7 the opposite detachable extremities thereof. The central portion 5, as,

well as the opposite extremities 6 and 7, are of A-shape, the interiorspace thereof adapted to be tamped with the dirt, or material of the railroad bed. The tie being of A-shape, the same will yield under the weight of a passing train, and thereby accomplish that degree of cushioning efiect incident to a wooden tie. The opposite extremities of the central portion 5 of the tie receive the detachable extremities 6 and 7, and when these' detachable extremities are applied, the length of the tie is complete. The extremities of the central portion 5 of the tie are provided with recesses 9 therein which form. lips 10,

and the inner extremities of the detachable portions 6 and 7 are provided with similar recesses 12, forming lips 13. The rails 14 rest upon the top of the ties and the bases thereof are received in the opposing recesses 9 and 12, the lips 10 and 13 being received over the top of the bases of the rails. These recesses 9 and 12 are of V-shape, whereby the bases of the rails are wedged therein when the detachable portions 6 and 7 are applied and connected with the central portion 5. Ears 15 are cut out of the central portion 5 of the tie and bent at right angles to the body of the latter, and the inner extremities of the detachable portions 6 and 7 are provided with similar opposing cars 16. These cars 15 and 16 are connected together by means of bolts 17, and by tightening the nuts 18, the detachable portions 6 and 7 will be drawn inwardly, causing the bases of the rails 14 to be tightly wedged in the recesses 9 and 12 by reason of the lips 10 and 13. The central portion 5 is provided with cut out lips 19, which extend on the interior of the tie and engage in the bed of the track for the purpose of preventing the tie from moving longitudinally under the influence of centrifugal force of a moving train, or from pressure exerted on said ties in a longitudinal direction.

While I have described and illustrated herein a specific form of the invention, it is understood that I am not limited thereto and that the same may be modified and varied without departing from the spirit of the invention, or the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is '1. An A-shaped metal railroad tie, comprising a central portion, and detachable end portions received by the central portion and adapted to be secured to the latter, the opposite extremities of the central portion and the inner extremities of the end portions having opposing V -shaped recesses therein ad ltpted to receive the bases of the railroad ral s.

2. A metal railroad tie, said tie being of A-shape and comprising a central portion, receii e the bases of the railroad rails, and and detachable end portions received by the the tie having inwardly extended portions opposite extremities of the central portion, adapted to engage in the bed of the railroad.

the opposite extremities of the central por- In testimony whereof, I aflix my signa- 10 5 tion and the inner extremities of the end ture.

portions having opposing recesses adapted to GEORGE L. WOOD.
