LOADING-MACHINE Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed May 8,1919. Serial No. 295,609.

To (1:25 whom it may concern:

Be it known that I, Nonron A. NEWDICK, a citizen ol the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Loading-Machines, of which the following is a specification.

This invention relates to loading machines adapted to gather and load materials of many kinds but the particular embodiment of the invention herein shown and described being more particularly intended to load coal in the mine into the mine cars.

A primary object of the invention is to provide a single unitloading machine of the character above indicated, constructed in such manner that the discharge end of the gatheringconveyer may be maintained in operative position with respect to the mine car, even thou h the truck of the loading machine and t e mine car may be located upon a sharp curve. In machines of this character it is necessary to provide sufficient overhang of the gathering conveyer at the rear of its supporting truck to permit the mine car to be manipulated therebeneath to distribute the load evenly within the mine car. It is apparent that with sufficient overhang to permit the manipulation of a mine car of even moderate length beneath the discharge end of the conveyer, such discharge end will, if the curvature of the track is such as to cause the truck and the mine car to lie at an angle with respect to each other, tend to move laterally beyond the track and consequently beyond the mine car;

The present invention contemplates the provision of a single unit loading machine in which means are provided for permitting the support upon which the gathering conveyer is pivotally supported from its truck, to be shifted bodily laterally to compensate for the tendency of the discharge end of the gathering conveyer to move laterally beyond the mine car under the conditions set forth, whereby such discharge end will be maintained in a position to discharge into the mine car, irrespective of how sharp the curve mgy be upon which the work is being done.

11 the accompanying drawings, WhlCll are 'merely illustrative of the principles constituting'the inventive thought,

Figure 1 is aside elevation of a loading machine constructed in accordance with the ing wheels for said truck, these wheels being preferably, though not necessarily, flanged to engage the track upon which the mine car 7 travels. At 8 I have diagrammatically illustrated a motor which through pinion 9 and gear 10 is adapted to impart movement to the wheels 6. If desired, sprockets 11 and 12 mounted upon the axles of the truck may be connected by a sprocket chain 13 to cause all of said wheels to be driven from the motor 8. Trunnioned at 14' in the frame of the truck is a saddle casting 15. extension 16 of this casting is provided with tongues 17 and 18 which enter corresponding grooves 19 and 20 formed in the saddle oasting to adapt the rearward extension 16 to have a bodily transverse movement upon the saddle casting 15. In order to impart such bodily movement to the extension 16 said extension is provided with a threaded lug 21 which constitutes a nut and which engages a screw 22. A sprocket 23 upon the end of this screw is connected by a chain 24 with a sprocket 25 upon the shaft of a motor 26. It is apparent that if this motor, which is preferably an electric motor, be energized, rotation will be imparted to the screw 22 and that this will in turn impart bodily lateral movement to the extension 16.

A gathering conveyer 27 is pivotally mounted at 28 in the rear end of the extension 16 and swings about the axis constituted by said pivot so that it may sweep back and forth in a substantially horizontal plane across a mine floor, it being understood that in the drawing this conveyer is merely diagrammatically illustrated, being of a well known type, such, for example, as illustrated in my co-pending application, Serial No. 96,723, filed May 10, 1916.

This type of gathering conveyer comprises a pan 29 divided by a central housing 30 into slideways 31 and 32 in which the flights 33 travel, it being understoodthat these flights are adapted to travel in either direction and that the conveyer is adapted to A rearward gather coal when swung in either direction. The flights 33 are carried by chains indicated at 3st to which motion is imparted from a motor Clips 36 upon the top of the extension 16 engage over an arcuate ring 37 carried by the underside of the pan 29, these clips being disposed upon the of a circle struck from th center of the pivot 28. It will thus be seen that as the conveyer swings back and forth it will gather coal or other material and discharge it from the rear end of said cenveyer into the mine car 7 and that it the truck of the gathering conveyor and the mine car move to sharply angular positions when working about curves in the mines, the conveyer may be shifted bodily laterally with respect to its supporting truck to keep its discharge end over the mine car.

It is to be noted that the support of the saddle casting is between the axles of the truck so that the weight of the conveyor and of the coal being loaded is equally dis tributed upon the driving wheels of the truck. Furthermore, this aids in counterbalancing the weight upon the gathering end of the conveyer and relieves friction between the nose of the conveyer and the mine floor.

It is to be understood that the invention is not limited to the precise construction set forth but that it includes within its purview any changes coming within the terms or the spirit of the appended claims.

Having described my invention, what I claim is:

1. In a loading machine, a supporting truck, a saddle casting trunnioned thereon about a horizontal axis, a member slidably mounted upon the saddle casting to move sidewise, means for imparting movement to said member and a gathering conveyer mounted upon said member.

2. In a loading machine, a supporting truck, a saddle casting trunnioned thereon about a horizontal axis, a member slidably mounted upon the saddle casting to move sidewise, means for imparting movement to said member and a gathering conveyer pivotally mounted upon said member to swing about a vertical axis.

3. In a machine of the character described, the combination with a supporting truck, an element trunnioned about a horizontal axis upon said truck, a second element slidably mounted for sidewisc movement upon the first named element, and a gathering conveyer pivoted upon the second element.

1-. In a loading machine, the combination with a supporting trurlt, oil. an element mounted thereon, a second element slidably mounted upon the first named clement a, screw carried by one of said elements and engaging the other for imparting sidewise movement to the second element with respect to the first element, means for operating said screw and a gathering conveyer pivoted upon the second element to swing about a vertical axis.

5. In a loading machine, the combination with a supporting truck, oil an element mounted thereon between the axles of the truck, a rearwart'l extension slidably mounted upon said element to move sidewise, means for imparting movement to said rearward extension and a conveyer supported upon said extension.

(3. In a, loading machine, the combination with a supporting truck, of an element mounted thereon between the axles of the truck, a rearward extension slidably mounted upon said element to move sidewise, means for imparting movement to said rearward extension and a conveyor pivoted upon said extension to swing about a vertical axis.

In testimony whereof I atlix my signature.

NORTON A. NE'WDIGK.
