Specication of Letters Patent.

Patented Aug. 29, 191W.

Application led December 28, 1914. Serial No. 879,366.

To all whom t may concern Be it known that I, ALFRED AYRD MELLOR, a subject of the King of Great Britain, and resident of 400 St. J ames street, in the city of Montreal, Province of Quebec, in the Do-` minion of Canada, have invented certain new and useful Improvements in Attach ments for Unloading Apparatus, as described in the following specification, which is a full, clear, and eXact description of the same.

The invention relates to improvements in attachments for unloading apparatus as described in the present specification and illustrated in the accompanying drawings that form part of the same. Y

The invention consists essentially in the novel means employed for directing the material from a vehicle and depositing it as desired during unloading operations.

rThe objects of the invention are to devise an apparatus that will facilitate the discharge of a load from vehicles, particularly railway cars containing` loose material, and at the same time avoid any interference with the means of unloading, to effect a reduction in expense of labor in such operations, to lessen the period oit' time required for distributing the material deposited and generally to provide an apparatus of a durable nature that will not be in the way during the ordinary travel of the vehicle and which will be simple to operate and cheap to manufacture.

ln the drawings, Figure 1 is a vertical sectional view along the center -line vof unloading plow showing frame applied thereon to which the improved device is iiXed. Fig. 2 is a side elevation of unloading plow showing the invention aiiixed thereto. Fig. 3 is a cross section on line 3 3 showing plow and the invention in elevation. Fig. 4 is a half plan view of the invention and half sectional view on line 4 4 of Fig 8.

Like numerals of reference indicate corresponding parts in each ligure.

rThe numeral 1 indicates a railway car of the type used for ballast, loose earth, sand or like material, such cars being used largely in railway construction, the various cars of a train being connected at their open ends lby plates or gangways, so that there is an uninterrupted passage from one end of the train to the other. After each car is loaded and the train hauled to its destination, the material is deposited by an unloading plow of anysuitable type and which is drawn from one end of the train to the other, subsequent of course to the opening of the side doors in the walls of said cars. This practice has been carried on for many years and in all its details is well known to those versed in the art. n

There are single and double plows, that is to say, plows for unloading one side ot' the car and plows for unloading at both sides simultaneously. The double plow is illustrated in the accompanying drawings, though this invention is equally etlicient as an attachment to a single plow, the dierence being that one flash board is used instead of two. The flash boards or plates are supported by frames from the plow and in the drawing the numeral 2 indicates the two rearor main mold boards while 8 indicates the mold boards of a pilot plow, and as these parts of theplow are those that most intimately concern this invention, the plow frame and braces will not be described herein, it being suliicient to say that these mold boards are' properly and rigidly held by frames in such a manner that they can be drawn lfrom one end of the train to the other and clear the earth, sand, gravel or other material from the sides of the cars through the side door ways.

The flash boards or plates 4 are pivotally supported at the lower ends of the connecting bars 5, the latter being in pairs and preferably in angle form. The said bars 5 are joined to the flash boards 4 by means of the angle bars 6 extending across the boards 4 at intervals. v Y

The adjusting bars 7 are pivotally secured at the inner edge of the flash boards 4 and each has a row of holes 8 therethrough. The said bars 7 extend outwardly between the members of each pair of bars 5, though it is not necessary to have an adjusting bar for every support, still it is preferable.

The adjusting bars 7 are held in the desired position between the bars 5 by the pins 9, this position being changed according to the material and the work at the place of the discharge. rl`he connecting bars 5 at their `upper ends are pivotally joined to the brackets 1 0, said brackets being of plate form andhaving the vertical rows of holes 11 and 12, both extending from the pivot 13 at the lower end joining the bars to the brackets so that the Hash boards 4 may be `further adjusted in their positions by the use of one or other of said rows of holes as sov the case may be, and in the lower and working position of the flash boards, pins are inserted through corresponding holes in the connecting bars 5v into and through the bracket holes, thus holding the bars pei'- fectly rigid in respect to the brackets so long as the unloading opera-tion continues.

The brackets 10 are rigidly secured to the l the pilot mold boards 3 and toward its rear from tbe main nn'old boards 2. The uprigbts 19 are rigidly secured to the pilot niold boards 3 and support the cross bar 20, to whieh tbe forward cross bar of the pivoted frame is 'secured by the pivot 21.

The nprights 22, 23 and 24 are rigidly secured to the main mold boards2` and each pair, of said uprights support corresponding cross bars, the centerP cross bar 25 being joined to a cross beam 17 'or :tbe upperl` frame by a pivot '26, the rear pivot joint being reinforced by the diagonal braces 27.Y The posts 28 are secured to tbe cross beams 17 by the angle brackets -y 29 and from their upper ends carry the block and tackle 30 forraising and lowering the arins 14, con-g sequently the connecting bars 5, brackets 10 and flash boards 4 are lifted andlower'ed by said tackle, saidV connecting bars 5V being first relieved from their" pin connection with the brackets 10 and allowed to on their pivotal connection with said brackets thus in their upper position the flash boards will rest on the cross beams '17,- which is.

plainly shown in Fig. 3, the arms le being in a vertical position.y The positions of the brackets 10 change conse'qiient upon the change of the position of the said arns 14, towhich they are rigidly attaohed and the positions of tbe connecting bars 5 still remain vertical and carry the'fl'ash boards e at their lower ends onthe cross beanis 17. The parts will all fall into place' very nat'- ur'ally on lowering the, arms 111, and connecting bars 5 to the brackets 10, to which they are pinned through one or other of the vertical rows of holes. The flash boards are then adjusted by means of the bars 7 and pinned to the required slant. A As the plow moves forward the meld boards of the plow throw the material off the side of the car and this material is guided bythe flash boards away troni the track and the line of travel of the vehicle.,

`Thedevic'e is 'of inestir'nable value in unt loading work and i`s` intimately associated with. the work of an unloadingy plow, though other 'uses may be found for it, also the parts may be arranged and constructed dinerently so long as the main elements re.- main as set forth in the claims for novelty following. v
