RAILVAY-TIE.

Specification of Letters Patent.

Patented July 23, 1912.

Application filed September 9, 1910. Serial No. 581,126.

I To a l whom it may 007100111.

Be it known that I, CanMrO. BENTON, a citizen of the United States, residing at Grainticld, in the county of Gove. State of Kansas, have invented certain new and useful Improvements in Railway-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 his invention relates to railway ties and has for an object to provide a tie that will be sufiiciently elastic to yield under the weight of passing trains, and will have novel means for limiting the yielding movement of the tie so as to prevent injury to the tie under severe conditions of service.

In the accompanying drawings, forming part of this specification :Figure l is a side elevation of a. railway tie constructed in accordance with my invention. Fig. :2 is a cross sectional view taken on the line 2--2, Fig. 1. Fig. 3 is a top plan view of the tic. Fig. 4 is a longitudinal sectional view taken on the line M, Fig. Fig. 5 is a cross sectional view taken on the line 55, Fig. l.

The railway tie comprises a pair of superposed oppositely turned channel members 10 and 11 the upper member being adapted to telescope into the lower member. The lower or base member is designed to be embedded in the ballast of the road bed and the upper or head member supports the tratlic rails on its web.

Arranged adjacent the opposite ends of the head member are pairs of spaced angular clamps 12. these clamps being: arranged upon opposite sides of the trallic rail and having their free end portions :nhipted to be engaged over the rail ban; flange and having their body portions provided with openings .13 which register with threaded openings 14 formed in the head men'lber. these openings receiving the oppositely threaded ends ot' a stud 15, a nut 16 being threaded on that end of the stud which projects through the opening 13 in the clamp and retaining the clamp in position.

Seated within the base member are still helical springs l7, tin-so springs being disposed to underlie the rails clamped by the rail clamps. The terminal convolutions of each spring bear against the opposing faces of the base and head members and normally hold the head member in extended position,

that is to say. in its outermost position relatively to the base member. washer l5. is disposed within the bore oi the spring and bears with its outer edge against the lowermost convolution of the spring.

A bolt 19 is engaged through the central opening in the washer and through registering openings 20 formed in thcbasc and head members, the head of the bolt being; countersunk in the head member o iening as shown and bearing against the bottom face of the rail base flange. The threaded end of the bolt projects through the base member and. is equipped with a nut 2t which may be advanced or retracted upon the bolt so as to vary the tension of the heli cal spring. The function ot the washer above described is to prevent lateral displacement of the helical spring, due to vilnation of pas lug trains. it is clear that the proiccting tllli. ol' the bolt and nut being disposcd bel w the base number will gouge out a hollow in the road bed as the I head member is depressed against the pres sure of the spring by a passing train, it be ing understlmd that where the tie is to be used in tunnels and the like where the road bed is of solid rock that suitable openings will be drilled in the rock to permit of the ielding of the tie.

To limit the yielding movement of the head member so as to prevent mutilation of the tie during heavy trallic conditions, the open ends of the base member are closed by caps 22, these caps tittint. snugly against; the end edges oi the head member and cont'orn'iingr in outline to the outline of the latter. Arranged upon lhc inner face ol earlcap is a strip 3 3. thi strip bring sccurcd by bolts. rivets, or similar connectors to the cap or may be cast integral therewith if desired. This strip is arranged a slight distance be ow the upper edge of the cap and forms a stop against which the head member impinges under a normally heavy traffic. conditions. it is evident that when the head member is in ciuragcmcnl with thes stops carried by the clitl that tbc head member will be positively held against tun thcr yielding so that. no parts oi the tie will be injured.

For securing the caps in position, angular braces 24 are provided, a pair of these braces being arranged adjacent the upper edge of each cap and a pair being arranged adjacent the lower edge of each cap. ()no leg of each brace is bolted as shown at 23 to l t the cap and the opposite leg is bolted a shown at J6 to the adjacent; side wal of l the base member. The caps are tu' movably secured in position so as: r permit of the interior of the tie l lffljj ex posed when repairs are necessary.

In order that the tendency of the Mad member to yield abnormally under the weight of passing trains and thereby weaken the springs 17 may be minimized, the outer surfaces of the head member l], and also the opposing inner surfaces oi" tlfu base member 10, are faced and planed to a perfect lit the object of this being to cause the tie to be practically an airtight bonr partlnent, capable of withstanding a great amount of internal and external pressure. The object of this air-tight compartment Within the tie is to form an airtight eushion for the head member, distributing the of What telescoping movement does take place evenly throughoutthe tie.

Under heavy tratlic conditions the compartment within the tie may be partially filled with an inexpensive oil or other noncongealing substance so that the proper rcsisting power of the tie compression may be maintained.

b a t A nwi uel l s laimed i llY'J railway tie including a chanwnber and clnmnel base member, in-labor being turned. oppositely to an? telescoping into said base member, rail supporting means on the Web of said head member, spaced helical springs inter posed between both members and underlying said. rail supporting means, bolts engaged through the bores of said springs and terminally engaging said head and asc members, loose washers on said bolts supported upon said base member and spac ng the lower ends of said springs from sr d bolts, caps closing the ends of said base member and bearing against the end edges of said head member. and transverse cleats on the inner faces of said caps adapted to engage the underneath face of the head member web and limit telescoping movement of said head member into said base member.

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