comma (01. 238 -9346) 'Thisinvent-ion relates. to arail chairand more particularly 'toa railchair :which is" incorporated ma concrete railwaycross .tie for anchoring the railrto the tie.-

Anobject of theinvention is: to equip a concrete or' composition cross-tie with' arail chair having means secured thereto for lockingthe-base fiang'e or the rail' to the tie. Yet another obj'ectis to provide-a rail: chaiir adapted to be embedded a .concrete cross-tieandequipped with: means-for releasably anchoring the raiL to the tie. J'Stillanother objectis to: provide a concrete or. com position cross-tie having: one or two railtgchairs' embedded: therein andisupporting rails upon the tie, cooperating means: carried. by the rail chair:

beingv providedfor adjustably securing the base flange of the rail uponx the tie. Other specific objects and advantages-will appear-asthespecification proceeds.

The: invention. is illustrated. in. a sing'1e-,em-- bodiment, ;by the accompanying: drawings, will which- Fig.1 is a" broken perspective view of apparatus:

In the illustration, A designates, a concrete cross-tie and B desi nates a railway rail.

The crosstie-A may be formed of-a-ny suitable material. and in any suitable shape. I prefer; to employ concreteandeto. have the same reinforced.

Embedded within the concrete cross-tie is a rail chair I I, as shown more clearly in Fig. 2. In the specific illustration given, the chair H has side walls I2 flaring downwardly and outwardly and the bottom is closed by a bottom wall l3. The structure is provided also with atop wall M which extends across the central portion of the structure II and below the pad l0 and rail base flange B The flange I4 is provided with central slots I5 which extend inwardly toward the center of the top wall M. The top wall I4 is cut away near its ends to provide a recess l6 and the side walls 12 are also provided with notches I! which provide locking teeth between the notches.

The rail chair H is preferably closed at its ends with end walls l8.

The bolt 24 is correspondingly moved forward through the adjustment slot l5. The nut 21 is then tightened with a long wrench to secure the clamp firmly in position, as illustrated in Figs. 1 and 3.

With the structure shown, the rail can be laid quickly in position and secured rapidly by rotating the nuts 21. A firm grip of the jaw 22 is obtained by the teeth structure permitting the adjustment of the clamp.

It is common practice with the railroads to use a new rail of high grade on certain important main tracks for a number of years and then after the rails are somewhat worn, to remove the rails and to use them on other tracks where the traffic is not so heavy and the train speed not so high. Further. by reason of the great stress placed upon therails today through the use of high speed heavy locomotives and cars,

Any threaded-structure;for

It will be understood that the clamping structure and the rail chair structure may be modified considerably to meet diflerent conditions. Ifdesired, the adjustment teeth heretofore mentioned may be omitted and instead, the clamp may contween said slots adapted to shank of said bolts, and nuts engaging the outer ends of said bolts for confining said clamps upon said rail flange.

2. A rail chair adapted to be imbedded in concrete and comprising a hollow box having bottom, side, end, and top walls, saicl'top wall terminating short of the end walls to provide a Well therein,

-said top wall having a bolt-receiving slot extending inwardly from each well at each end of the box and providing a continuous surface besupport the entire base flange .of a railroad rail and be reinforced thereby, a bolt'having its head received within sist of a plug portion received within the endrecess of the rail chair; the clamp being provided with the jffiWflngLWith the bolt passage. 11in the modification given in Fig, 5, the rail chair Ila has unserrated side walls and is provided with an end well 29 adapted to receive a depending plug or block 30 formed integrally with the clamp 3|. The clamp 3| -is provided with the bolt opening 32 and witha forwardly extending jaw 33. In thisstructure, the clamp is not adjustably mounted but is made to fit a particular structure and the block 30 serves to anchor the clamp within the recess, 29 of the rail chairlla... H While in the foregoing specification, I have set forth a single. structure in considerable detail for the purpose of illustrating embodiments thereof, it will be understood that such details of structure may be varied widely by those skilled in the art without departing from the spirit of myinvention.

I claim:

l. A rail chair adaptedto be imbedded in a concrete body and comprising a box having bottom, side, end, and top walls, said top wall being,

continuous except at pointsadjacent the ends of the boxawhere .the top wall terminates and leaves tion of said top wall being of sumcient length to abut the full width a rail base flange support and be reinforced thereby, said top wall being provided at each end with an inwardly-extending slot, a bolt having its-head received within said box and its shank extending through said slot at'each end of said box, a pair of clamps each having a downwardly projecting plug portion shaped to be snugly received within one of said wells and thereby anchor said clamps withinsaid wells, said clamps having also a-forwardlyextending -jaw adapted to engage the baseflange of the rail, each of said clamps having an opening extending therethrough for receiving the a well therein, the central. continuous porthe box and its shank extending through the bolt slot at each end of the box, and a pair of clamps each having an anchor portion engageable with the well in the end of the boxand each having a forwardly-extending jaw adapted to engage the base flange of a rail, said tured to receive said bolts, the outer ends of said bolts clamps upon said rail flange.

and nuts engaging for confining said 3. In combination with a railroad rail having an enlarged base flange, a chair forsupporting said rail on the central portion of the top Wall of.. said chair, said chair box having bottom, side,

to provide two wells therein, said top wall having a bolt-receiving slot extending inwardly from each well at each end of the box but providing a continuous surface between the inner ends of said slots for supporting said rail and being reinforced thereby, a bolt having its head received within the box and its shank extending through the bolt slot at each end of the box, and apair of clamps each having an anchor portion engageable with the-well in the end of the box and each having an engaging the top of the and nuts engaging the outer end confining said clamps upon said rail flange.
