To all whom it may concern:

Be it known that i, SIDNEY A. increase, a citizen of the United States, residing at Habana, Island of Cuba, have invented certain new and useful Improvements in Raih Way-Ties, of which the following is a specification, reference being had to the accompanying drawings. a

' This invention relates to railroad ties and more particularly to reinforced concrete ties.

The principal object of the invention is the provision of a railroad tie of the above stated character which embodies a reinforcing structure and a reinforcing bar member disposed longitudinally and medially of said structure, and provided with means at the opposite ends thereof for clamping the rail flanges securely upon the tie.

A further object of the invention is the provision of a cement tie whichis reinforced in such a way to provide a tie that will vbe of durable and substantial design, and one which will stand a great deal of wear and tear without the liability of chipping or crumbling away.

A still further object of the invention is the provision of a cement tie embodying a bar disposed longitudinally thereof and having its terminal ends bent to form substantially rectangular loops embedded within the tierfiange engaging clamps secured atone end to the bar adjacent the looped ends and projecting up through the tie and dis posed above in spaced relation thereto, and removable clamps adapted to be secured to the looped ends of the bar member so as to overlap the rail flanges to secure and hold the rail in position, the tie being further provided with hearing plates embedded therein and disposed beneath the rail flange clamp. With these and other objects in View, the inventioncomprises the various novel features of construction, combination and arrangement of arts as will be more fully described here nafter and set forth with particularity in the appended claims. :1 Referring the drawings, Figure 1 is u lan view of my improved cement tie show- ,lmg a pair of rails secured in position there'- on; Fig. 2 isa vertical longitudinal sectional view taken on the line %---2 of Fig. 1; Fig. 3 is a transverse sectional view taken on the line 3 -3 of Fig.2;and Fig 4: is a perspec tive view of'the til-shaped reinforcing strucspecification or lsctters retest.

Similar characters of. reference are used to denote iilreparts throughout the aocompartying drawings and the annexed specificatron. a

Referrin more particularly to the draings the reterenee character 1 indicates my improved cement tie, upon which, as shown,

are clamped the. rails 2, which may he oif any tormqor construction, this shown; heinggot the t is ordinarily used tor street cars and theirs. I

The tie 1 -has cmhedded therein a tishaped reinforcing structure which comprises spaced vertically disposed recitation lar frames that sawed suhstsntio. l3!

A longitudinally disposed rein rcing har' i 5 is arranged medially of the thshaped structure and has its opposite bent up and around to form ;a ,suhstantially rec tangular loo 6., The ends oifthe bar a are I bent upward y to form the loop 6 atapoint Below and in vertical alinement-with' the r pen the tie so as to provide means for remroroir p,- the tie at a point where the load strain s placed upon the tiel Rail clamps 7 have tl'ieir lower inner terminal ends securely fixed to the bar 5 etc aointaadjaeentthc loo' .6 was indicated at 8 t. rough the mediocre" suitable .fasteriing devices, the'clamps extending upwardly and hor zontally nspeecd relation to the tie so as to overlap the rail danger The upper face of the tie is cut away so as to bare the upper portion 9. of the loops 8' whereby the ends eilthe removable clamps 10 may be secured thereon. 'Each or the loops 6 terminates in ahorizontally reject ing portion 11 and has extending up t rough the portions 11 and .19 thereof squared bolts 12 which have their 11 per'ends'reducod and threaded as at 13 w erehy the apertured': ends of the removable clampsfilO- may :be. placed thereover so as to rest uon the por tion, 9 of the loops and securely position through the medium. of mas M.

sition upon the tie, the flapper; otthe rill,

m5; as in such the nuts 14 screwed down so as to hold the 'latter clamps in position. The bolts 12 are squared so that they will be prevented from turning within the tie.

Bearing plates -15 are embedded Within the upper face of the tie between the clamps 7 and 10 so as to provide substantial bearing surface for the bases of the rail whereby any possibility of the rails causing the tie to chip or crumble will be eliminated. As shown, the upper surface of the bearing plates are disposed in a plane slightly above that of the top of the tie. These bearing clamps may, if desired, be further secured to the tie through the medium of suitable anchored elements 16 secured at the end face thereof and extend down into the tie.

From the foregoing description taken in con ection withthe' accomian 'in drawings, the advantages of construction, and

the.method of operation of the invention will be readily apparent to those skilled in the art to u\hich the invention. relates, and

While I have described the principle of operationof the invention together with the device which I now consider to be the best embodimentthereof, I desire to have it understood that such changes may be made What I claim as new is:

appended claims.

Having'thus fully described the invention when desired as are within the scope of the 1. A concrete tie having a reinforcin bar. disposed longitudinally therein, the on .s of the her being bent up and around to provide looped ends, the terminal ends of said loops extending inwardly below and in spaced relation with the bar, rail flange engaging clamps connected to said bar adjacent the looped ends thereof, and removable rail flange engaging clamps connected to said looped ends of the bar.

2. A. concrete tie embodying a U-shaped wire structure extending throughout thelength thereof and consisting of a pair of spaced vertically disposed rectangular frames, a Wire mesh covering and connecting said frames together, a reinforcin bar disposed longitudinally and medially o said U-shaped structure, the ends of the rein forcin bar being bent up and around to provide substantially rectangular loops, fixed rail flange engaging clamps secured to the bar adjacent the looped ends, and removable rail. flange clamps mounted upon the looped. ends of the said bar.

oured to the reinforcing bar adjacent said loops, and bearing plates embedded within the upper face of the tie between the said clamps.

In testimony whereof ii hereunto alli); my

signature in the presence of two Witnesses.
