LOADING BOOM.

Application filed March 22, 1923 Serial No. 626,744.

My invention relates to a loadingboom for delivering relatively finely divi ed materials, such as coal, to railroad cars or other conveyors. It hasior particular purpose to provide a booin adapted to deliver coal to a' mixed train wherein some of the cars are box cars and some are open topped. A further object is to rovide a boom of the class described whic receives coal from a source lower than the to of a box car. Other objects will appear rom time to time in the course of the specification and claim.

I illustrate my invention more or less diagrammatically in the accompanying drawings wherein- I Figure 1 isa side elevation with parts in section;

Figure 2 is a plan view.

Like parts are illustrated by like symbols throughout the specification and drawings.

A, A are the structural members of any suitable tipplc, the details of which form no part of the present application. A is the end of any suitable ty of shaking or delivery chute or screen own which coal or some similar material may be dischar ed.

B is a loading boom which is pivote as at B in the yoke B upon a horizontal axis. The yoke B is in turn pivoted on a swivel and adapted to rotate about a bolt B which is mounted in the block B forthe pur ose of which any bearing surface or mem er B? is provided.

C is a track herein shown as an I-beam which is supported in any suitable manner,

for example upon the A-frames C, C, andv over-lies the outer end of the boom B. Ada ted to travel along the track is any suita le supporting element C rovid'ed with upwardly and inwardly extending arms C, terminating in rollers C adapted to ride along the lower flanges of the track C. Any suitable means are provided for manually -.or mechanically drawing the element 0 back and forth along the track C to rotate the boom B about its pivot. The height of the outer end of the boom is controlled, for example, through the pulleys D, D, the cable D and hoist C D is a cable passing around the sheaves I), D and secured at each end to the supporting element C D is a pulley adapted and thus actuate the boom B about the ing to any suitable power source not herein shown.

D is any suitable depending oke, its arms being pivoted at the lower ends as at D to the boom B.

.The outer end'of the boom, preferably adjacent its connection to said yoke, is downwardly inclined as at B The boom ma able manner an at its upper end with any suitable motor E which, through the chain of gears E drives the belt or conveyor sprocket E about which passes the endless conveyor E which extends throughout substantially the entire length of the boom and passes about the terminal sprocket E the belt being guided and supported in an suitable manner along the length of the om. E is any suitable icking table platform mounted at one si e of the boom.

It will be realized that while I have illustrated a working mechanism, many changes might be made in the size, sha e, number and disposition of parts without eparting from the spirit of my. invention.

The use and operation of my invention are as follows: a

In manyocoaling plants, the point of delivery of the chute or screen is lower than the necessary clearance for a box car. It therefore becomes. desirable that when box cars, as well as open cars. are to be filled by a loading boom that the boom be pivoted at a point lower than the top of the box carl This necessarily involves pivoting the boom to one side of the track along which the cars are to be propelled. It also necessitates a boom which, while pivoted at a lower point, is so shaped that it can deposit coal at the bottom of a box car without dropping it so as to cause breakage.

The loading boom I employ is of the endbe constructed in any suitless conveyor type, having .a belt or conveyor which positively conveys the coal deposited on one end of the boom to the other end of the boom, regardless of the angle at which the boom is positioned. .To enable this boom when pivoted at one end at a point below the top of a box car, to deliver coal not merely to the open door of the box car, but over the edge and to the bottom of an open car, I rovide it with a downwardly inclined on section. This permits it to deliver coal directly to the is herein shown as provided tically horizontal position.

bottom of an open car though the upper or inner section of the boom is in a prac- This is' illustrated in full lines in Figure 1. The boom, being pivoted to one side of the track, necessarily delivers its coal along a path inclined to the longitudinal axis of a car, as shown in Figure 2. The boom being pivoted on a horizontal as well asa vertlcal pivot, it may be raised and lowered to compensate for various heights of cars and to permit the end to be dropped into the car bottom and to be lifted from the car when the car is filled. The car, of course, may be moved progressively forward as the coal is deposited, until it is filled from end to end, and the boom is then lifted to permit the car to pass on.

\Vhen a box car is to be filled the boom is not merely lifted, but is swung about its vertical pivot until it lies parallel with and along the sidelof the track. as shown in dotted lines in Figure 2. The box car is perferably spotted with its central door 0pposite the end of the boom and any suitable coaling chute is provided to receive the coal from the boom and deliver it through the box car door, the end of such a chute being diagrammatically illustrated by dotted lines in Figures 1 and 2. Preferably a box car loading device of anysuitable type is used, the details of which form no part of the present invention, but the coal delivered to the box car may, of course,

be distributed in the box car by manual labor 1 if so desired.

I provide my boom with. a picking table tal and a vertical pivot, means for raising and lowering said boom about said horizontal pivot, and for rotating it about said vertical pivot to swing the outer end of the I boom over the track, the length of the boom being substantially greater than the distance between the vertical pivot and the track, the outer end of the boom being downwardly inclined in relation to and integral with the body of the boom.
