RODERICK w. BRYANT; or oMg nA, NEBRASKA DOUBLE SLOPE IR E-RAILING FROG Application filed November 14, 1928. Serial No. 319,243.

The invention relates to rerailing block s; Patent No: 1,681,2811issued adapted to be used for replacing the wheels of locomotives and railway cars upon tracksafter derailment thereof, and has for its ob:

the'invention resides in the combination and 5 ect to provide blocks having channeled members adapted to arch the treads of rails, provided with upwardly flange engaging surfaces terminating adja cent the inner sides of the rails, whereby the wheel flanges will be positioned where upon further movement of the Wheels, the wheel treads will engage the rail treads and the wheel flanges will engage the rails.

A further object is with apertured lugs for the reception of i spikes for securing the blocksacross ties and i the under sides of the blocks with lugs adapt ed to imbed in the ties for preventing lateral displacement of the blocks.

A further object is to proportionthe inner sides of the rail arching members, whereby said inner sides will rest uponthebases oi the. rails for rigidly supporting the rail sides of the blocks and reducing the strain on the rail arching members.

A further object is v sides of the block with flattened portions on which the wheel flanges rest when they reach 30 the point of re-railment and'to provide the central portions ot-the blocks with shoulders adjacent the flattened portions which, upon movement of the wheels in either direction,

will prevent the wheels from going down either incline no matter from which side of 'the'block the wheels have beenelevated to re-railm'ent position.

. A further object is to provide re-railing blocks mounted adjacent rails and having upand inwardly extending wheel .re-

moved to re-railing positions from either end of the blocks without changing the blocks,

thereby obviating the" necessity of providing instance the type a plurality of blocks, for

and I inclined wheel the inner sides of to provide the blocksv atthe left hand side of Figure shown in Figure 8.

to provide the upper above and other arrangement of parts as hereinafter set forth, shown claimed, it being understood that changesin in the drawings, describedand the precise embodiment'of the invention may be made within the scope of what is claimed without departing from the spirit of the invention. ,r

In the drawings: Figure .1 is a a railway showlng the blocks applied thereto. Figure 2 is an end view of the blockshown 1- I 1 Figure 3 is an end View of the block shown at the right hand side of Figure 1. r

v Figure ,4 is a top pla-n'view of the block; shown in FignreQ. 7 v

Figure 5 is a side elevation of the block shown in Figure '2. v i a V Figure 6.is a top plan View of the block Figure 7 is a side elevation of the block shown in Figure 3. v T Figure v8 is a verticaltransverse sectional view taken on line 8-8 of Figure 5.-

Figure 9 is a vertical transverse sectional viewftaken on line'9v9 of Figure 7 f Referring tothe drawings, the numeral 1 designates rails and2cross ties ofthe usual construction to which the rails are'securedby spikes 3. Disposed adjacent the nails 1 are re-railing blocks 4 and 5,, which blocks have their under sides provided;withjdownwardly extending sharpened lugs 6 adaptedto imbed v I in'the' cross ties for preventing lateral'movement of the blocks when in'vposition-if The blocks are additionally held against displacement by :nieansof Y spikes 7 which extend,

through apertured' lugs 8' and into the cross ties. Block}; ls placedto the outside of one top plan view of a section of of the rails and block 5 to the inside of the other rail.

The blocks 4 and 5 are provided at one side thereof with inverted channeled members 9 which arch the treads of the rails and onto which the wheel flanges are guided by means hereinafter set forth. The blocks 4 and 5 at their sides adjacent the rails engage the rail bases 10 for relieving the strain on the channeled members when the weight of an engine or car is on the blocks.

Referring specifically to. the block 4, the opposite ends of said block incline downwardly from the central flat portion 11 and are provided with downwardly inclined flared channels 12 onto which the wheel flanges are forced from either side of the block. As the wheel flanges move upwardly they engage the shoulder 13 of the block and are guided inwardly onto the channel 9, which is a fiat surface, and into a position where as the wheel rotates, it will move to a position in engagement with the rail 1 and with its flange engaging the inner side of the rail.

The block 5 is provided with downwardly inclined flared channels 14: into which the wheel rolls according to the direction of movement of the wheel and. the wheel is guided toward the adjacent rail lby engagement,

with the flanges 15, and when the wheel reaches the central position, the wheel flange will engage the webs 16 or" the blocks and will be in a position where upon movement of the wheel in either direction the tread of the wheel will engage the tread of the rail 1 and the flange of the wheel will engage the inner side of the rail. It will be noted that by providing double ended re-railing blocks, only two blocks will be necessary, and the wheels may be placed on the rails by moving the same in either direction.

From the above it will be seen that re-railing blocks are provided, which may be used for re-railing rolling stock wheels moving in either direction, thereby obviating right and left hand blocks of the single type now in use wherein it will require four blocks. It will also be seen that the side of each block is provided with a channeled member arching the rail in engagement therewith, and that the inner lower edge of the block rests on the rail base thereby positively bracingthe block and relieving the strain 'on the channeled member. v

The invention having been set forth what is claimedas new and useful is A double slope re-railing block comprising an elongated body member adapted to be dis posed to one side of a rail in engagement therewith, an outward and downwardly eX- tending member car ied by the body member and adapted to arch the tread of a rail, upwardly inclined recesses carried by the ends of the body member, whereby wheel flange signature.
