COAL-LOADING MACHINE.

Specification of Reis'suetdLetteiS Patent: Reisgugd Apt 18 1922.;

Original No; 1,362,889, dated December 21, 1920, Serial No. 96,723, filed May 10, 1916. Application for reissue filed January 21, 1922. Serial No. 530,996.

T all whom it may concern:

Be it known that I, NORTON A. NEWDIGK, a citizen of the United States, residing at Columbus, in the county of Franklin, State of Ohio, have invent-ed certain new and useful Improvements in Coal Loading Machines, of which the following is a specification.

This invention relates to a material gathering, conveying and car-loading machine primarily adaptable as a transportable mineworking machine for gathering loose or excavated coal and, loading it into a mine-car.

The main object of the invention resides in the provision of a machine of this character. which can be readily and conveniently transportedwithin a mine from place to'plac-e and in a feeding capacity for progressively advancing the machine to bring its nose or gathering end into. and beneath a pile of coal or material to be removed for continuous self-gathering and car-loading operations.

The gathering end of the machine is adapted to sweep or swing sidewise for increasing the gathering range, as from one side of the mine to the other, and for delivering the gatheredor collected coal intola mine-car.

The delivery end of the machineis adapted to be centrally disposed over the car for loading to a heaping capacity. To this end, my invention resides broadly in the combination of the two types of conveyers arranged one in advance of the other and constituting agathering conveyer and a dis charging or delivering conveyer. The gathering conveyer is mounted at its rear end to swing about a vertical axis for swinging the forward end laterally and also about a hor1 zontal axis for adjusting the forward end' rcrtically, said. conveyer having a pair of parallel corresponding elevating planes over which the flights, carried by a reversible transmission belt, translate, whereby the planes serve alternately for conveying and elevating the gathered material in an advancing or draft direction. The discharging or delivering conveyer has a single plane central of the planes of the gathering conveyerwith a hopper at its receiving end open in the line of draft of the conveyer and disposed beneath the discharge end of the gathering conveyer, for receiving the material discharged. therein from the gathering conveyer, and centralizing the material upon the receiving end of the delivering conveyerwhich leads out of the hopper and forms the base thereof. The vertical axis of the gathcr ngconveyer and the hopper are located with respect to each other in a connected operative position of the conveyer, so that the hopper will be in a receiving position with relation to the discharge end of the gathergathering conveyer for all positions of angularity of the gathering conveyer with respect to its truck, and for the positions of angularity of the two trucks with respect to each other, as well as the positions of angularity of the two conveyers within the range of horizontal swinging adjustment of the gathering conveyer, or the positions of angularity the parts may occupy due to the curvature of the track over which the machine is transported.

7 Among the other objects of my invention is the provision of a structure whereby the gathering conveyer is mounted adjacent its rear end to permit of its various movements and adjustments.

The preferred embodiment ofmy invention is shown in the accompanying sheets of drawings, in which similar numerals refer to similar parts throughout the several views, and in which:

1t outer end with This shaft 34 is rotatably journaled in a yoke member designated 35, which yoke member is provided with depending legs 36 having bearing portions 37 'rotatably mounted on the axle 15 as shown more clearly in Fig. 9. The upper end of the shaft 34 carries the drive sprocket 1 and through the drive con nections just described, the conveyer as a whole may be set in operation by simply shifting the two clutch parts 21 and 22 in engagement with each other.

It is by means of this yoke member, that the conveyer as a whole and the conveyer pan 5 specifically, is mounted to sweep the mine floor, or, in other words, is mounted to swing about avertical pivot. The upper portion of the yoke member 35 is provided with a neck portion having a shoulder 38 upon which the bearing member 39 rests. The conveyer pan ,5, is itself rigidly connected to this bearing member through the medium of the rivets shown at 40 and further, the underside of this pan at this end of the conveyer is provided with an arcuate guide member 41, this guide member being circular with the exception of theopen or cut-away portion 42 of the rear end of the pan as is'shown in Fig. 4, through which the coal is discharged. ,This cut-away portion terminates abruptly the rear ends of the conveying planes or ways of the gathering conveyer and provides what may be termed a free or open flight sweep between the flames or ways. A substantially z-shap edslid'e member 43 mounted upon bosses 44 of the arms of the yoke member, cooperates with the guide member 41 to give the conveyer pan a substantial bearing at some considerable distance from its rotative center or from the shaft 34. This arrangement just described, permits the conveyer as a whole to sweep the mine floor or pivot about a vertical center which happens tobe the shaft 34 and it also permits this conveyer to be swung about a horizontal pivot, which, in this case, is the axle 15. This swinging about the horizontal axis is desirable in that it permits the elevation of the front or nose portion of the conveyer to permit its ready transportation from place to place in the mine. The rear portion of the yoke member 35 is also provided with a pivoted dog 45 which, when the conveyer is in its operative position as is shown in Fig. 3 engages the edge of a bolster 46 forming a portion of' the supporting truck.

This arrangement is provided to relieve the yoke member of undue strain as the conv'eyer is being forced into the coal heap. When the conveyer is forced into the coal heap, the natural tendency would be to cause a pivoting about the axle 15, and, therefore strain the connections between; the two memhere 41 and 43. It is to relieve this strain that the" dog 45'is provided, it being, of

course, understood that'this dog is released when it is desired to elevate the front end of the conveyer. I

The mechanism for causing this gathering conveyer to sweep themine floor will now be described. A jack post or other temporary anchoring means such as shown at 47 is provided and set up adjacent one wall of the mine room or entry. Engaging this jack post is a hook 48 onto which the cable49 is connected. This cable passes over a pulley 50 secured to the frame portion of the section 9 of the conveyer through the medium of either of the eye bolts 51 and from here it passes rearwardly and is connected with the winding drum 52 mounted on the axle 14 as is shown in Fig. 8. This drum is pro vided with a laterally projecting sleeve 53 onto which the half 54 of a friction clutch is rotatably mounted. The other half of this clutch is designated 55 and is slidably keyed to the sleeve and is, controlled in its movement by'means of the arm 56 pivoted at its lower end as is shown at 57 and provided with a shifting yoke 58. To the upper end of this arm the operating rod 59 is pivotally connected as shown at 60 and by operating this rod 59 through the medium of a handle 61 projecting out through the side frame, the friction clutch may be thrown in.v

or out. The portion 54 of this last named friction clutch is provided with a sprocket 62 which sprocket is in line with a sprocket 63 rigidly secured to the shaft 20 on which the main friction clutch is mounted. A chain 64 connects the two sprockets 63 and 62 and, therefore, upon rotation of the shaft 20 this chain 64 is set in operation to rotate the portion 54 of the friction clutch on the shaft 14 and when then the operating handle 61'is grasped to bring the two parts 54 and 55 of the friction clutch on the axle 14 into engagement, the winding drum 52 is also set into operation to wind up the cable 49 and by the shortening of the cable length in this manner, the gathering conveyer as a whole drawn across the mine floor about its vertical pivot 34. When a sweep across the entire floor has been made, the jack post may be removed. and set up on the other side of the mine room, the cable extended and the operation repeated;

In order to automatically prevent the gathering conveyer from forcing itself out of the coal heap after the nose end has been pushed or fed into the same by the operation just described, I have provided one end of the drum with a ratchet face 65, Fig. 10, in connection with which'the dog 66 operates. This dog is pivoted as at 67 to the side of the motor frame and the drum 52 is rotated, the dog runs idle, but upon stopping of the winding action, this dog 66 drops into engagement with one of the teeth on the ratchet wheel 65 and, therefore, prevents re- "verse rotation of the drum 52.

The underportionloffthis'hopper further,

frame ofthe truckasisy int designated 89 a11l beeause 7 65 become sufficiently engaged by ment of the conveyer as a whole. The bottom or trough portion shown at 93 which may also be termed a conveying plane or a nontraveling way or run-way cooperates 5 with the flights in moving the coal out of the hopper to its point of discharge and is likewise movable with the conveyer as it swings about its pivot 86 inasmuch as it forms a rigid part of veyer chains themselves pass over tail sprockets 94 mounted on the axle of the truck 86 and head sprockets 95 loosely mounted on a head shaft 96.. The rear portion of the discharge conveyer is so proportioned that it lies substantiallyparallel with the mine floor when in its operative position as shown in Fig. 6 and extends over the same after the manner illustrated in Fig. 1.

From the arrangement thus far described, it will be apparent that the hopper S3 is so proportioned to receive coal discharged from the gathering conveyer, no matter what may be the position of this conveyer as regards movement about its vertical center. From here the coal is conveyed by means of the discharging conveyer into the mine .car and inasmuch as the discharging conveyer never changes its relative position as regards a swinging movement about a vertical pivot, it follows that this conveyer always stands in central alinement with the center of the hopper and is, therefore, always in a proper position to withdraw the coal from .the hopper. By means of the rearwardly extending portion as is shown in the drawings, the car may be loaded from its frontend and gradually pulled forward by a mine locomotive or any other means as the coal piles up. In addition, the trimmer may pile the coal to a level in the car above or equal to that occupied by the mine car itself as it is pulled forward. It will be observed that the bottom '93 over which the flights 82 travel consists of a plate or plane comprising sharply inclined portion which constitutes a substantial part of the bottom as well as the rear wallof the hopper proper and that this sharply inclined portion merges into a substantially horizontal portion, which projects rearwardly beyond the truck 8 1. An important advantage arises from this construction as follows :Frequently 7 very large lumps of coal .are discharged into the hopper; If these lumps become securely engaged with the flights they arecarried up the sharply inclined portion or rear wall. and out of the hopper. If insecurely, engaged with a flight they fall back into the hopper. Thus the provision of the sharply inclined 6.0 iortion in conjunction with traveling transverse flights, the whole associated with a hopper one wall-of which is formed by said *sharply inclined portion assures that no huge lumps will leave the hopper until they a flight, it

the conveyer frame. The conbeing manifest that if such engagement is firm and secure enough to cause the lump to be lifted'agains't the force of gravity from the hopper it will be secure enough to insure the proper conduct of the lump to the discharge end of the conveyer. The importance of this will be appreciated when it is understood that throughout the operation of the machine miners are working about it. A large lump of coal toppled over the side of the discharging conveyer because of its insecure engagement with a flight would be likely to kill or injure a workman.

The manner of driving this discharging conveyer is as follows: A motor 97 is suit-- ably supported on the truckand is provided witha drive pinion 98 meshing with a drive gear 99 mounted on a shaft 100 rotatably journaled in the 'truck frame. This shaft is also provided with a sprocket 101 in alinement with a sprocket 102 over both of which a chain 103 passes. The sprocket 102 is mounted on a. shaft 10 1 and carries a second sprocket 105 in alinement with a sprocket 106 carried by the head shaft 96 over which the driving chain 10 7-passes. Thus, when themotor is set in operation, the conveyer as a whole, isdriven by the driving arrangement just described.

When transferring the conveyer from place to place about the mine, it is desirable to lower the upper portion in order to give more clearance or head room and inasmuch as this conveyer frame is pivotally mounted about the axle 86, this may be done in the following manner. A pair of toggle links 108 are pivoted respectively to the truck frame and the conveyer-support and hingedly connected together as shown at 109.

At this connection 109, I have attached a 5 chain 110 which is designed to be wound on a drum 111 which may be hand operated by means of the crank 112. This crank is held against reverse motion by means of the pivoted dog 113. The chain 103 passing over 10 sprockets 101 and 102 is of such length that it attains its proper tautness when'theupper portion of the conveyer is substantially parallel with the mine floor and the slack which occurs when the conveyer is lowered 115 is of no consequence, inasmuch as the conveyer is not driven when in such lowered position. 7

From the foregoing description, taken in connection with the accompanying sheets. of drawings, it will be apparent that I have provided a type of coal handlmg machine which is particularly adapted for many types of mines. The machine, operates in a minimum of head room and by means of the rearwardly extending portion of the discharging conveyer, this conveyer may be on a level practically with the. level of the mine car, reliance being had on the attendem. 9? t immer f r su tably piling the coal s arrangement permits the I oadedfcar 1nd he b an-m t y wlthput stopping theyope I I gathering"convyer the cqal gathered N- pp Theflessnt al characp r nf th .ac

The conveyer flights move about horizontal'axes respectively at the opposite ends of the belt transmission, as distinguished from the flight travel of the gathering conveyer to provide for a discharge in the draft line of the conveyers so that the coal cannot be thrown off of the car by the flights.
