BALLAST-UNLOADER.

Specication of Letters Patent.

Patented May 10, 1910.

Application filed September 20, 1909. Serial No. 518,501.

To all 'whom it may concern:

Be it known that we, CHARLES B. KING and HARRY J. BARNHART, citizens of the United States, residing at Marion, inthe 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.

This invention relates to ballast unloaders, and more particularly to that type of unloader shown and described in Letters Patent No. 714,193, granted Nov. 25, 1902, to George W. King and assigned to The Marion Steam Shovel Company, assignee of the present invention.

The object of the present invention is to provide a ballast unloader of this type in which both the pilot or front guide and the plow or unloader proper will be of a well braced and strong, durable construction; in which the force exerted by the plow upon the pilot to drive the latter ahead of the former will be applied directly to the frame of the pilot; and in which the draft bar may be adjustably connected to the plow and may be adjustably supported near its forward end from the pilot.

IVith these and other objects in view our invention consists in certain novel features' and in certain combinations and arrangements of parts hereinafter to be described, and then more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of an unloader embodying our invention, showing the pilot in section; Fig. 2 is a top plan view of such an unloader; Fig. 3 is a front elevation of the same; Fig. 4 is a detail view of the plow nose; and Fig. 5 is a fractional detail view of the rear frame member of the pilot.

In these drawings we have illustrated one embodiment of our invention and, as here shown, the front guide or pilot 1 is of the same general construction as that shown in the above-mentioned Letters Patent and comprises a front arch or frame member 2r arches and rigidly secured at the edges to the arches. To this end, angle irons 6 are secured to the adjacent faces of the arches and other angle bars 7 extend between the two arches near the upper edges of the fender plates i and the plate 5 is riveted to these angle irons. This arrangement of the plate 5 serves to rigidly brace the frame members of the pilot and provides a very strong, durable construction having a large amount of resist-ing power.

The unloader proper or plow 8 also conforms in its general construction to the plow of the above-mentioned Letters Patent. The present plow, however, has its nose 9 cast in a single piece and provided with a forwardly extending cutting edge 0r blade 10 and rearwardly diverging and upwardly inclined webs or walls 11, to which are rigidly secured the forward edges of the mold boards 12 of the plow. The nose 9 is so arranged with respect to the rear arch 3 o-f the pilot that it will engage this arch in such a manner as to apply thereto the force necessary to move the pilot ahead of the plow, thus eliminating intermediate connections and providing a much stronger and more reliable connection. To accomplish this the upper forward corner of the nose is cut away to form a shoulder 13 which is of sufficient height to enable the same to engage the arch 3. The nose is preferably loosely connected to the pilot to prevent the separation thereof under abnormal conditions, such as when the unloader is passing from one car to another and the cars are of differentheight. This connection is, in the present instance, formed by mounting on the arch 3 of the pilot rearwardly extending lugs or brackets 14 arranged on opposite sides of the nose 9 and having vertical slots 15. A pin 16 extends through an aperture 17 in the upper portion of the nose and through the slots 15 in the brackets 1% and forms a connection which, while it prevents the separation of the pilot from the plow, allows a considerable degree of movement of these parts relatively one to the other. The slots 15 are preferably of a width greater than the diameter of the bolt, so that, under normal conditions, the bolt will not engage the edges of the slots, and, consequently, none of the force exerted by the nose on the pilot will be applied to the pin 16. The brackets 14 also serve to prevent the lateral displacement of the pilot relatively to the nose.

l/Vhen it is desirable to utilize a counterweight in connection with the unloader the lever 25 of the counterweight may be pivotally connected to lugs 26 on the rear arch 3 and the rear end of the lever may be connected to the pin 16 by means of a link 27, and, in this manner, the pin 16 serves not only to connect the pilot to the plow, but also to connect the counterweight thereto.

The blade 10 of the nose has one or more apertures 18 adapted to receive a pin 19, by means of which a draft bar 2O is connected to the plow. In the present instance we have provided a series of apertures 1S arranged vertically of the nose and are thereby enabled to adjust the point of connection of the draft bar to the plow to accommodate the draft to the class of material and the size of the load being plowed off. The forward end of the draft bar 2O is supported from the front arch 2 of the pilot by means of a supporting bar 21, which is pivotally connected to the draft bar and is adj ustably connected to the arch 2. This connection is, in the present instance, formed by extending the supporting bar 21 through an apertured bracket 22 which is rigidly secured to the front arch. The supportingl bar 21 is provided with a vertically arranged series of holes 23 adapted to receive a bolt 24, by means of which the position of the supporting bar 21 in the bracket 22, and, consequently, the elevation of the front end of the draft bar 20, is adjusted. lIhe supporting bar 21 is loosely fitted within the apertured bracket 22 so that it is free to move vertically therein to accommodate itself to the rise and fall of the draft cable as it passes over rocks or elevations on the car ahead of the pilot. The downward movement of the support 21 and the forward end of the draft har is limited by the bolt 24: to maintain the same in proper relation to the point of connection of the draft bar to the nose of the plow. The forward end of the draft bar can also be adjusted to cause it to exert a downward pull upon the pilot. While the support 21 and the forward end of the draft bar have a free vertical movement, they are held 'against lateral movement and the pilot will be moved laterally with the draw bar when the cable tends to move the draw bar to one side or the other.

It will be observed that, by means of the plate connected to the front and rear arches of the pilot, this member is rigidly braced in all directions and that the construction thereof is rendered very strong and durable; that the nose of the plow proper is of cast metal and therefore exceedingly rigidv and very strong and that it is provided with webs or diverging walls, to which the forward ends of the mold boards of the plow to accommodate the same to the character of Y the material, size of the load and to other conditions which may vary from time to time.

We wish it to be understood that we do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

I-Iaving thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is
