BALLAST-U N LOADER.

SPEIFICATION forming part of Letters Patent No. 714,193, dated November 25, 1 902. Application filed August 12I 1901. Serial No. 71,673. (No modela To all whom it may concern:

Beit known that I, GEORGE W. KING, a citizen of the United States, residing at Marion, in the county of Marion and State of Ohio,

have invented certain new and useful Improvements in Ballast-Unloaders, of which the following is a specification, reference being had therein to the accompanying drawings.

zo This invention relates to ballast-unloaders, and more particularly to unloaders of the type set forth in Letters Patent No. 306,688, granted October' 14, 1884, to Edward Huber and Henry M. Barnhart, and No. 384,111, granted I5 June 5, 1888, to Henry M. Barnhart.

My present invention is in the nature of an improvement upon the structures set forth in the two prior Letters Patent just enumerated, and has for its obj ect to render the same zo stronger and more durable and at the same time increase its efficiency of operation by causing it to discharge all of the material from the car at the same time, especially adapting it for use in connection with cars which have outswiuging sides or side doors hinged at their tops.

To these and other ends the invention consists in certain novel features which I shall lnow proceed to describe and will then par- 3o ticularly point out in the claims.

In the accompanying drawings, Figure 1 is a plan view, partly in section, of an unloader embodying my invention in one form. Fig. 2 is a side elevation of the same, partly in ver- 3 5 tical section. Fig. 3 isa rear elevation. Fig.

4 is a front elevation, and Fig. 5 is a sectional perspective on a somewhat enlarged scale.

In the said drawings, 1 indicates the fender 4o or front guide, which in its general construction is identical with the fender set forth in the prior patents hereinbefore referred to, comprising a front arch 2 and rear arch 3, connected by the fender-plates 4 and by the diagonal braces 5, extending from the top of the rear arch to the point of junction of the fender-plates and front arch. In order to strengthen this front guide or fender and enable it to better resist the strains to which it 5o is subjected, I connect the tops of the front and rear arches by means of braces 6, secured at their rear ends to the bracket 7, which connects the plow to the front guide, while their front ends are connected to the guidingbracket 8, which serves to restrain the draftrod 9 laterally at its front end. It will be ob` served that this draft-rod is a double rod bent upon itself, the bracket 8 passing down between the two arms or members, and thus .serving to prevent lateral deliection of the 6o rod. The rear ends of the draft-rod are connected to a pin 10, extending from the plow through slots 11 in the arms of. the bracket 7. A pivoted link 12 and weighted lever 13 connect the front end of the plow to the rear arch of the fender or front guide, as in Patent No. 384,111.

The plow proper, which is indicated at 14, comprises a vertical cutter 15 and inclined moldboards 16 diverging reawardly there- 7o from. These moldboards are braced at intervals by means of braces, each consisting of a vertical transverse sheet of metal 17, strengthened at its top by an angle-bar 18, riveted to the upper edge thereof, and at its bottom by an angle-bar 19, riveted to the lower edge thereof. The lateral edges of each sheet are braced by means of angle-bars 20, riveted to the said edges of the sheet and to the adjacent inner surfaces of the moldboards. In 8o order to prevent lateral bending of the cutter or nose-piece 15, which sometimes occurs in very large plows, I provide inclined braces 21, one on each side thereof, the rear ends of said braces being secured to the outer face of the moldboards near their upper edges, while the forward ends of said braces are secured to the upper edge of the cutter or nosepiece at a point Well in front of the junction of said upper edge with the moldboards. In 9o unloaders of this type as heretofore constructed the rear guide has consisted of a low open frame pivotally connected with the plow proper, and it has resulted from this vconstruction that when the device is in use some of, the material drops over the rear ends y of the moldboards onto the rear guide and through the same onto the deck of the car and is therefore not unloaded. In order to remedy this defect, I connect the rear guide rigidly to roo the plow proper and carry up its sides at an angle corresponding with and as highl as the dinal members 25 and diagonal braces 26.4

The sides of the rear guide (indicated at 27) extend up as high as the tops of the moldboards 16 and are inclined at the same angle, being united thereto at their forward edges by a line of rivets, as indicated at 28. They thus form rearward parallel extensions of the moldboards and are united by transverse braces similar to those which unite the moldboards, being composed of transverse vertical sheets of metal 29, riveted at their lower ends to the members 23 and 24 and having riveted to their upper edges angle-bars 30 and to their lateral edges angle-bars 3l, which are also riveted to the sides 27. The whole structure, comprising the plow proper and the rear guide, is then braced longitudinally by means of a through-bolt 32, passing thro ugh suitable apertures 33 in all of the transverse braces and having located on it between each pair of braces a tubular spacing-sleeve 34, which may be conveniently constructed of gas-pipe or the like.

It will be observed that by forming the sides of the rear guide into extensions of the moldboards the car is more electively cleared of material, as the same cannot fall back over the rear ends of the moldboards onto the car again, but is discharged from the car by these extensions. The material is, moreover, subjected to an outward thrust for a greater length of time, and this is of particular advantage where the apparatus is used with cars having laterallyoutswinging sides or doors hinged at their tops, which tend to materially retard the discharge of the ballast. When the rear guide shown in the prior Letters Patent is employed, the high stakes, top rail, and swinging doors or sides retain a good deal of the material, which drops back on the car after the plow has passed. This is avoided by the construction which I have devised. By reason of the rigid connection of the rear guide to the plow proper this latter is rendered much more steady in operation and the entire plow is made stronger and more rigid. The plow proper is held up or supported vertically in a more efficient manner in moving from one car to the next, and the lateral guiding of the plow-point is much more efcient and steady than where there is a hinged connection between the rear guide and the plow proper. Greater durability is also obtained by reason of this construction, since there are no hinged connections to become loosened or strained by reason of lateral thrusts upon the plow proper.

I do not wish to be understood as limiting myself strictly to the precise details of construction hereinbefore described and shown in the accompanying drawings, as these details may obviously be modiiied without departing from the principlerof my invention.

Having thus fully described my invention, what I claimas new, and desire to secure by Letters Patent, isi 1.
