CAR-REPLACER.

SPECIFICATION forming' part of Letters Patent No. 757,299, dated April 12, 1904.

Application filed September 23, 1903. Serial No. 174,327. (No model.)

To all whom it may concern.:

Be it known that I, HARDIN QUTNGY HALL, a citizen of the United States, residing at Louisville, in the county of Jefferson, State of Kentucky, have invented certain new and useful Improvements in Oar-Replacers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a car-replacer, and particularly to a device embodying a replacing-block and a frog-block disposed in contact with the opposite rails of a track.

The invention has for an object to provide a novel and improved construction of thereplacer-block whereby it may be formed in a single casting and rendered reversible in use by the shifting ofthe position of the elevating-bar and adapted to cooperate witha frogblock by which the lateral movement of the car to be raised is effected, so that the iianges of the vwheels are adapted'to rest within the track without thenecessity of a sliding movement of the car or a sudden jar thereof.

A further object of the invention is toprovide an improved formation of frogblock adapted to be formed of a single casting and provided with means for retaining the same in reversible position Without the necessity of spiking or any other connection with the permanent road-bed or rail.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the ap- .pended claims.

' 6 is a similar view of the elevating-bar carried by the socket of the replacer-block. Fig.

of the usual construction, which form the track and are secured upon the ordinary crossties A' in the usual manner. In connection with these opposite track-rails the replacer B is provided and adapted to cooperate with the outer face of one of the rails. This block is preferablyformed as a single casting and is provided-upon its face next the rail with a rib B', adapted to contact with the web of the rail, and with arecessed portion B2 beneath said rib to receive the liange thereof. At the upper portion of the block the replacing-face B3 is provided, so as to lie above the tread of the rail and' extend slightly thereover, which face is curved or beveled from'its center toward the opposite ends, as at B4, thus providingfor the reversal of the block and also forming an incline to guide the iiange of the wheel from the elevating-bar C over the tread of the rail. This elevating-bar is provid ed at one end with a rectangular horizontally-disposed head portion O, from which the upwardly-inclined face C2 extends to the opposite end of the bar. The angular head O of this bar is adapted to vfit in a similar socket B5, one of which is provided at each side of the block, and the walls thereof are disposed at substantially a right angle to the bottom, so as to prevent any lateral movement of the bar within the socket and retain the latter in a straight line leading from the socket. For the purpose of preventing a longitudinal movement of the bar the lower end thereof may be provided with a pin or projection C3, if foundl desirable, to engage with the upper surface of the tie, whereby the bar will be held securely against any movement. The block B is provided at its outer face with a base-plate B, from which parallel strengthening-ribs B7 extend upward to the walls. of the sockets B5, While upon the Iunder face of this plate depending ribs l?.8 are formed and adapted to rest between adjacent ties to prevent any movement of the block parallel with the rail. For the purpose of preventing movement of this block laterally ,of the rail a tie-bar D is provided, having a head D provided at one end to engage the web of the rail, as shown in Fig. 2, and a recess D2 beneath this head to receive the flange of the rail, and the opposite end thereof is provided with an aperture D3, adapted to receive a screw-bolt D4, which is passed upward through the aperture Bg in the block B and there provided -with securing-nuts D?, so that the replacer-block is adapted for application and retention against any movement by the use of a single bolt and a tie-bar.

The frog-block E (specically shown in Figs. 7 and 8) is provided upon its upper face with an inclined portion E' and flattened horizontal portion E2. Extending through the inclined portion is a groove E3 to receive the flange of the car-wheel, which groove after reaching the horizontal portion E2 is bifur-m cated, and two diverging grooves E* extend therefrom. The outer wall of each of these grooves is cut away, as at E5, so as to permit the tread of the wheel to ride upon thel tread of the rail. This frog-block is reversible in position,.and for that reason each face thereof is provided for a portion of its length with a rib E, adapted to it and engage the web of the rail, While the flange thereof extends into a'recess E7, formed in the under face of the frog-block, while the upper portion of this frog-block beyond the cut-away ends E5 eX- tends parallel and in contact with the side of the tread of the rail. For the purpose of preventing movement of this block longitudinally of the rail a series of downwardly-extending lugs E8 are provided upon the under face thereof and adapted to fit between the adjacent ties on the road-bed, as indicated by dotted lines in Fig. 1. It will be seen that these lugs retain the frog-block against longitudinal movement, while any vertical movement thereof is resisted by the contact of the rib with the web of the rail, particularly when the Weight of the car to be elevated is placed thereon, so that any other fastening devices are unnecessary.

In the operation of the invention the car to be replaced upon the track will be brought into a position parallel therewith, as it has been found impracticable to attempt to replace a car upon a track when the wheels thereof are at an angle to the rails. The car is then placed parallel with the elevating-bar, so that the tread of the wheel will ride thereon, while the flange of the opposite Wheel engages the groove in the frog-block, and the car is thus raised to the top of the rails, after which a lateral movement is effected by the movement of the flange of the wheel along the diverging groove in the frog-block until the end of the groove is reached, when the Wheel- `iiange will be rested upon the tread of the rail without sliding or dropping thereon, so that injury to the replacing and frog block is prevented. Itwill also be obvious that the replacer-block carries the wheel riding thereon above the tread of the rail A, so that its flange may engage the inner face of this rail, While the frog-block is only of suiicient elevation to place the tread of the wheelI upon the railtread. It is also desirable to prevent any lateral movement or vswinging of the elevatingbar, and for that reason the same is provided with an angular head adapted to fit in an an- Hare effectually held against vertical movement by means of the ribs thereon engaging the web of the rail.

It will be obvious that changes may be made in the details of construction andconfiguration without departing from the spirit of the invention as defined by the-appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is-

l. A car-replacer, comprising a replacerblock having an elevating-bar extending therefrom parallel with the outer face of the rail, and a frog-block disposed V`parallel with the face of the opposite rail and provided with a groove therein diverging toward the rail at one end thereof.
