This present invention' relates to certainV new and useful improvements ina rail joint chair. V

The primary object of the invention resides in the provisionfof a rail joint chair which supports the rail on thepbottom of the flange as well as under the ball of the rail.

The invention has for another object the provision of a rail joint chair of the character stated which provides ample bearing on theties, thus eliminating theuse of `tie plates under the rail joint chair.

The invention has for a further object the provision of a rail joint chair of the character stated which makes the joint as strong as the rail, thus reducing the defiection when the wheels of the rolling stock pass over the joint.

The` invention has for a further object the provision of a rail joint chair of the character stated which provides a most substantial andf smooth joint, eliminating the noise, and preventing the wear on the end of the rails. n

The invention has for a still further object the provision of a rail joint chair of the character stated which can be readily rolled in a standard rolling mill in long bars, sheared and punched in the flange thereof for spikes to provide a substantial fastening to the ties without requiring any expensive machine work.

The invention has 'for a still further object the provision of a railrjoint chair of the character stated which may be produced at small cost, and sold at a popular price with good profit, thusproviding a commercially attractive proposition.

To the accomplishment of these and related objects as shall become apparent as the description proceeds, my invention resides in the construction, combination and arrangement of parts as shall be hereinafter more fully described, illustrated in the accompany ing drawings and pointed out in the claim hereunto appended.` j

The invention will be best understood and can be more clearly described when reference is had to the drawings forming a part of this disclosure, wherein like characters indicate like parts throughout the several views.

'In the drawings f Figure 1 is a side elevation of the improved rail joint chair, showing the same in use; and Figure 2 is a transverse vertical section therethrough, taken 'substantially' on the plane of line 2 2 of Figure 1, looking/in the directionindicatedr by the arrows.

Referring more in detail to the drawings, it is to be noted that the rail joint chair includes complementary members, each `of which has a base portion 6 adapted to fit under the rail base 7 and extend longitudinally thereof. Each base portion 6 has an outwardly directed longitudinal flange 8 through which spike openings 9 may be punched or otherwise provided for the' spikes 10 to beextended through and Adriven into the t-ies 11 across which the complementary members are mounted. These ComplementaryV members are provided with grooves or corrugations 6a on their under faces and are also adapted to rest in `depressions or pockets 12 provided therefor in the upper face of the ties 11 so as to prevent spreading of the rail. To compensate for this inclining of the complementary members7 they have their base portions 6 bevelled on their upper faces so as to support the rail base 7 in proper horizontal plane thereon. If desired, the

- grooves or corrugations 6a or the depressions or'pockets 12, or both, may be dispensed with and the complementary members 6 mountedy in upright position on the ties 11. The complementary members are employed at a rail joint and the body portions 13 of said members rising from'the flanges 8 thereof and eX- tending upwardly toward one another in slightly inclined planes-are adapted to ex" tend overV the upper face of the rail base 7 of the opposed rail ends forming the rail joint and said body portions 13 of the complementary members normally rest upon and bind on the upper face of the rail base'7, at the inner longitudinal edges 14 of saidv body portions 13 of the complementary members and near the connection of the longitudinal inner edges of the rail base 7 with the upstanding rail web 15. The upstanding or fish plate portions 16 of the complementary members rise from the body portions 13 ioo thereof so as to have their inner faces normally spaced from the opposite faces of the rail web 15. The upper edges 17 of the complementary members are bevelled or inclined outwardly so as to rmly engage the bevelled under faces 18 of the rail head or tread 19. The upper edges /17 of the upstanding portions 16-.of the complementary members Vbind against and at all times firmly contact with the under faces 18 of the rail head or tread 19. It is also to be 'noted that bolt openings'` 20 are provided in the upstanding portions 16 of the complementary members registering with corresponding bolt openings 21 Vin the rail web 15 to receive the bolts 22 extended through said web 15 of the rail and through the upstandinig portions 16 of the complementary members, with lock nuts 23 or thev like carried on the threaded ends of the bolts 22. Attention may be also directed at this time tothe main part of the base vportions 6 "of the complementary -members binding againstithe underface. of the -raihbase 7 gat all times. Likewise, Yitis to .be noted thatl the opposed edges ofthe -baseaportions 16 of the complementary members are vnormally spacedv vapart beneath the centre of theV -rail y g base 7 and spaces are also provided betweenl chair is subjected to exceptional strain and atl the other pointsthe parts are normally the outer longitudinal edges of ythe rai-l; base 7 and the Aupstanding inner walls between the 'base portions 6 yand the body portions 13 of said .complementary "members, thus permitting inward movement of saidV comple-- mentary members lon the opposite sides of f the rail sections, if required, for an adjustmentY of saidV complementary members and said Arail sections.

As the construction ofl the device lhas .-.thiis been described in detail, vbrief reference is now had to its use and Vmodus operandi z.

The rail ends are effectively and firmly held in the proper horizontal plane and outwardV spreading of* thev rail sections is prevented. Furthermore, the rail endV sections are firmlyl i held between and rclamped by the complef mentary members constituting the rail. joint separated, thuspermitting sufficient eXpansion and contraction of the parts, to assure the highest efficiency of results and automatic adjustment or regulation of they Various parts, with respect to one another. When required, the lock nuts 23 `may be readjusted on thezbolts 22, to bring the complementary the rails, at the joints thereof is preventedv by this improved rail joint chair.

From the foregoing. description taken in,

connection withv the accompanying drawings, it will be manifest that a rail joint chair is provided that will fulfill all the necessary requirements olf such adevic'e but as many changes could be made in the above description and -many apparently widely?- different embodiments of my invention' may be constructed within the scope ofthe appended claimy without departing from the spirit or scope thereof, it is intended that all matters contained in the said accompanying specification and drawings, shalll be interpreted. as illustrative and not in `a` limited sense.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is A rail joint chair including the combination with the opposed ends of rail sections and Across ties beneath thel ysame providedadjacent their ends with inclined pockets in their upper faces having upstanding outer end walls; of a `pair of complementary rail joint chair members having basexportionsV with their under faces beveled transversely and serrated for engagement with the bottom wall of said pockets in saidy cross ties; the outer chair member engaging against the upstanding outer endv wall of said. pocket to prevent outward movement of said 'complementary rail joint chair memberson saidv ties; said complementary rail joint chair members having recessesin their base vp0rtioiis to receive the base portions of said. rail sectionoends Awith'ftlie baseportions of said complementary rail joint chair members binding on the underface and the upper face of said base portions of the rail section ends said complementary rail joint chair sections having upstanding portions opposite the web portions of said vrail section. ends with the upper edges of said upstanding portions of the complementary rail joint chair members bearing against the under-face of the tread portions of said rail section ends; means for firmly retaining the upstanding portions of said complementary rail joint chair members in position on opposite sides of said yrail section ends; and means for rmly retaining i said base portions of the complementary rail joint chair member on'said ties. f

In testimony whereof I hereunto signature.'
