To all whom it may concern:

Be it known that I, BENJAMIN F. BROWN, citizen of the United States, residing at Lyndonville, in the county of Caledonia and State of Vermont, have invented certain new and useful Improvements in Rail-Handling Machines, of which the following is a specification.

This invention relates to a loading and unloading apparatus, and has for its object an efiicient construction of apparatus particularly designed for handling railroad rails, the invention consisting in certain constructions, and arrangements of parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following descrip tion and accompanying drawings in which:

Figure 1 is a side elevation of my improved apparatus for handling rails; Fig. 2 is an end elevation of the supporting framework; and Fig. 3 is a side elevation on an enlarged scale, of one half of the apparatus the parts being shown in section.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The working parts of my improved rail handling apparatus are mounted upon the bed or platform of a railroad car of the flatbottomed type, said bed forming part of the supporting framework of the apparatus, said framework also comprising end and intermediate standards 2 projecting upwardly from the bed 1, longitudinal side sills 3 secured to the upper ends of the standards 2, crossbeams 4 secured to the upper ends of the standards, and a middle upper sill 5 extending longitudinally and supported upon the cross-beams 4, as clearly illustrated in the drawings. The framework is braced by intersecting transverse tie rods or braces 6 secured to and extending between the standards 2, and is also braced by obliquely extending tie rods 7 secured at their upper ends to the ends of the side sills 3 and converging and se cured at their lower ends to the sides of the bed 1 at the middle thereof.

At each end of the car base blocks 8 are mounted. These base blocks 8 support hollow pedestals 9 braced by means of tie rods 10 secured to the upper ends of their corre sponding base blocks. Upon the upper ends of the pedestals 9 hollow bearings 11 are mounted, said bearings comprising preferably steel plates to which the inner ends of the masts or booms 12 are pivotally connected for movement about horizontal axes. Each boom 12 carries a preferably incased sheave or pulley 13 at its outer end and hoisting cables 14 are mounted to run over the respective pulleys 13 and thence over pulleys 15 mounted at the pivot ends of the booms, the said hoisting cables thence extending through the hollow bearings and pedestals and around pulleys 16 journaled in the base blocks 8 around other pulleys 17, and finally are secured to the adjusting drums 18 which are mounted in the base blocks 8, and which provide for the lengthening or shortening of the cables, as required. The pulleys 17 are journaled in the outer ends of plunger rods 19, the pistons of which are mounted for reciprocating movement in the longitudinally alined cylinders 20 to which air inlet pipes 21 are connected, the admission and exhaust of air into and from the respective cylinders 20 being governed by cocks 22 and the air being supplied to the cylinders from a common drum or reservoir 23 mounted on the bed of the car.

The drum 23 is provided with the usual pressure gage 2 1, and is designed to receive its supply of compressed air from the train pipe 25 of the car. In order to control or regulate the cooks 22, their handles are connected to link rods 26 which are in turn secured to the actuating levers 27 fulcrumed at the middle of the car as shown. By this means one operator may control both of the hoisting cables.

28 designates block and falls devices that are respectively secured to the outer ends of the booms 12 and whose cables are adapted to be fastened to cleats 28 secured to the respective pedestals 9, so that the booms 12 may be adjusted and maintained at the proper elevation or inclination.

29 designates upper boom supports that are connected to the inner pulleys of the block and falls device and that preferably consist of angle bars of steel that diverge downwardly and have their lower ends pivotally and detachably connected to the vertically disposed bars 30 secured to the outer edges of the end standards 2, said bars 30 being formed with a lurality of apertures so that the bolts whic pivotally connect the supports 29 with the bars may be removed and the connection between the bars and supports shifted to lower or raise the sup ports as desired.

29 designates braces that are secured at their inner ends to the sides of the end standards 2 and that project outwardly to the bearings 11 of the masts and to which bearings they are connected in any suitable way.

31 designates strain rods that are connected at one end to the other ends of the upper boom supports 29 and that are connected at their opposite ends to a longitudinally extending1 anchor plate 32 which is mounted upon t e middle sill 5 of supporting framework. The anchor plate 32 is formed with a plurality of apertures through any one end of which the connecting bolts for the strain rods 31 may extend, so as to adjustably connect said strain rods to the plate.

From the foregoing description in connection with the accompanying drawings. it will be seen that I have provided a simple, durable and efficient construction of loading and unloading device, the booms of which may be easily adjusted and maintained at diiferent elevations or inclinations, the pivot ends of the booms being mounted at relatively high oints by means of the pedestals 9 so that the booms may be easily operated over cars with relatively high sides. The block and falls device of the respective booms are strongly braced by means of the supports 29 and strain rods 31, and also in such a manner as to be capable of easy adjustment so as to accommodate themselves for the different inclinations.

It is to be understood that the a paratus in working order is designed to be p aced between two cars for loading and unloading, and may be used on any part of a train that has an air brake connection with the main reservoir of the locomotive, the supply of compressed air for actuating the apparatus being transmitted to the drum or reservoir 23 through the train pipe 25 of the car.

Having thus described the invention, what is claimed as new is:
