MACHINE FOR LOADING RAILS SPECIFICATION forming part of Letters Patent No. 756,736, dated April 5 ,1904.

Application filed August 19, 1903. Serial No. 170,017. (No model.)

T0 a/ZZ whom it may concern/ Be it known that I, FRANK THOMPSON, acitizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Loading Rails, of which the following is a specification.

This invention is primarily intended for use on coal, stock, or fiat cars employed in construction-work on railroads and is adapted to be moved from car to car along the train, loading or unloading rails from the next adjoining car, although the machine is adapted for use in other capacities in which a movable derricl; is employed.

The invention consists in the method of arranging the parts to rapidly and easily perform a maximum amount of work with the least possible inconvenience and delay in moving the machine from car to car; and the invention consists in the means by which the machine is operated and also in the arrangement of parts by which the upright portions of the machine are adapted to be lowered for passage beneath overhead structures.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings illustrating the invention, Figure l is a side elevation oi' the entire device in operative position upon the top of a fiat-car; Fig. 2, a side elevation showing the supporting post or upright lowered and the boom raised; Fig. 3, a front view with the boom removed, and Fig. 4 an enlarged sectional detail of the hinge and one of the pulley-wheels on the upright.

rThe apparatus is arranged upon a flat-car A of suitable size, mounted upon wheels A, carried by journals c, mounted within journal-supports a, which enables the apparatus to be readily moved along the top of a fiat-car from which the operation of loading or unloading the next adjoining car takes place.

At one end of the flat-car A is mounted a boom B of a length to give a large radius oi' action, and said boom is provided at its inner end with a pivotal socket o, provided with ears b', through which transversely passes a pivot-pin L2, pivoting the boom to a pivotal sleeve b", which latter is rotatably mounted between forwardly-projecting ears 54 by means of a pivot-pin 65, the ears being located on a flat plate b,- suitably secured to the front end of the car. This arrangement allows of an easy vertical and lateral movement of the boom, which movement is necessary to secure a large radius of action in the loading' operation.

Near the front end of the car to which the boom is attached is arranged an upright post or support C, which latter consists oi' a short fixed section o and a long movable section c. To the rear tace of the fixed section is attached a plate 02, provided with a rearwardly-extending frame C, between the walls of which is rotatably mounted a pulley-wheel or sheave c3. (Best shown in Fig. 4:.) The frame is provided with upwardly-extending ears 04, which are arranged to cooperate with ears c5, bolted or otherwise secured to the movable section of the upright by means of bolts c or otherwise, and through the ears a pivot-pin c7 passes, pivoting the ears of the two sections together and forming a hinge which enables the movable section of the upright to be rearwardly lowered for the purpose of allowing the entire apparatus to be moved beneath an overhead obstruction, thereby greatly adding to its efliciency and increasing its lield ot' operation. To the front side of the lixed section c is secured an angular plate D, extending forward at an angle oblique to the fixed section, and on the top face of the angular plate are mounted two guide-wheels or sheaves d, held in operating relation by means of a strap or plate d', which guide-wheels serve to allow of the easy passage of a rope ory cable D therethrough, whichrope or cable extends outwardly to the end of the boom and there passes over a pulley-wheel or sheave cl2, pivotally mounted by means of a pivot-pin da, which latter passes through a yoke di, which straddles the end of the boomand permits the rope or cable D to pass therethrough. As shown in Fig. 4, a hole or passage E extends through the lixed section of the upright and the plate secured to the rear face thereof in line with the angular plate on the front face of the upright, which passage allows the cable to be carried around the pulley-wheeler sheave 03, whence it extends upwardly around a movable sheave F, which latter is carried by a piston-rod f, operated within a pressurecylinder F', which latter is strapped, by means of strapsf', to the rear'face of the movable section of the upright and is movable therewith. Pressure is supplied to the cylinder through a pipe G, controlled by means of a valve g, suitably located in the pipe, which pipe passes down along the side of the movable section of the upright and terminates in an elbow g', to which a pipe for supplying pressure to the cylinder is attached. As shown, the pressure employed is compressed air, which is supplied tothe pipe Gr through a rubber hose g2, which terminates in a coupling g3, which latter is adapted to be coupled to the pipe supplying compressed air to the air-brakes oi' the train, which arrangement allows the flat-car supporting the operative mechanism to be moved from car to car along the train and to be successively coupled to the air-brake pipes on the respective cars without the necessity for employing a long pressure-supply pipe, which arrangement adds greatly to the economy and rapidity of the operation and adapts the apparatus for use in places where it might otherwise be impossible to secure a suitable supply of pressure. Other powers may, however, be employed-such as steam, hand, or electric-without changing the nature of the invention. The upright when in raised position is supported by means of tixed braces H, which latter are secured to arms it, fxedly attached to the sides of the movable upright by means of bolts la', which latter may be readily removed when it is desirable to lower the upright. The upright is further supported by means of rods or cables I, rearwardly extending from the upright to the body of the iiatcar, and said rods or cables are connected with strap-irons 1I and e, located on the upright and on the sidesoi' the car, respectively. The forward and rear supports serve to hold the upright inrigid position when raised, but allow it to be readily lowered when necessary. Near the top of the upright is located aforwardlyextending plate J, bolted to the front of the upright, on the upper face of which plate is located a guide-loop j', through which passes a lift-cable'J', which latter is lixably attached to the yoke on the end boom and extends upwardly over the top oi' the upright when in raised position and is secured at the rear end of the car to a strap j'. rl`his arrangement limits the downward movement of the boom, and when it is desirable to lower the upright a passage K in the movable section of the upright, after which the end of theicable may be secured by any suitable means to the car or elsewhere.

In order that the invention may be used on closed-end coal-cars or others having sides, auxiliary wheels L are provided, one on each corner of the car or truck, said wheels being journaled on journals Z. which latter are L- shaped and have their 'upturned ends pivotally mounted in journal-boxes L, one on each corner of the truck, allowing the lower ends Z of the journals to project out at right angles to the car when in use and to be turned back around the corner ofthe car and out of the way when .not in use. Springs Z2 on the journals serve to force the wheels outwardly and allow for differences in the width of the cars upon which the truck is used, and at the same time hold the flanges Z3 on the wheels L against the inner faces of the sides of the car, as shown in Fig. 3, and pins Zet prevent the wheels from being forced from their journals. rlhis arrangement allows the truck to be hung, as it were, between the sides of a car and moved along without touching the bottom of the car.

. In use the fiat-car supporting the operative mechanism is moved onto one of the cars composing a train and begins to unload the rails upon the next adjoining car, which operation may be accomplished as the construction-train is slowly moving along the track, and after the car first operated upon is unloaded the apparatus of this invention may be moved onto said car, from which the unloading operation may be performed on the next adjoining car, and so on throughout the entire length of the train. The arrangement is one which allows the boom to be adjustably supported at a suitable elevation above the car and to be moved from side to side through a wide radius. The cable D, passing over the pulley-wheel at the endoil the boom, may be IOO IIO

secured to the rails to be unloaded and easily the invention is one which allows of the ready adjustment and adaptation of' the parts to varying conditions of' use.
