Merritt and Clarence L.-Muntz, Bowerston, Ohio Application March 26, 1949, Serial No. 83,582 13 Claims. (01. 104-472) This invention relates to an improved powerfurnishing apparatus for use in connection. with the trackways of underground mines in furnishing power for propelling cars in trip formation along the trackway.
Hitherto such ear-feeding mechanisms, sometimes known as car hauls, have been character ized by their permanency in operating positions. Most of such mechanisms have been difiicul-t, when once erected, to dismantle and move from one working location in a mine to another. Modern mining practice, through the use of mechanically operated mining and loading machines, provides constantly changing working locations or faces, and it is important that car feeders be freely portable and easy to install in order that they may be kept in as close order as is practicable with the. changing working faces of a mining drift.
Accordingly, it is one of the objects of themesen't invention to provide 7 a freely portable .and readily installed car-feeding mechanism involving a frame structure having a horizontall disposed chain driven by a reversible electric motor, and wherein the chain is formed with car-engaging detents so disposed on the chain as to effect predetermined longitudinal movement of a trip of cars along an associatedtrackway in each operating cycle of the mechanism.
It is another object of the invention to provide a car feeder for use in association with the track structure of a mine haulage-way in which the feeding mechanism may be placed on the floor or trackties of the haulage-way without necessitat'- ing any extensive excavation in the floor of the haulage-way to produce a receiving pit for the feeder.
A further object of the invention is to provide a car feeder of the character indicated in which car-propelling detents are carried by the opposite runs of a motor-propelled chain which has its opposite runs disposed in the same horizontal plane.
A further object of the invention is to provide a car feeder which embodiesa frame having at one end thereof apropelling chain sprocket which is driven by an. associated motor and motiontransmitti'ng gearing disposed in such a manner as to require the formation of but a shallow pit of limited dimensions in the mine floor atone end of the feeder frame.
It is a further object of the invention so to construct the feeder that when the same is to be moved from one working locationto another, the parts-thereof will be so formed as to admit of 2 their ready separation and placement on cars. for convenient transportation.
In the accompanying drawings:

Fig. 7 is-a diagrammatic view showing a typical working face and a haulage-way of an underground mineof the character in which our carfeeding mechanism is adapted for use.
Referring more particularly to the drawings, the numeral [0 designates a trackway composed of a pair of parallel rails II supported on transverse. ties [2, the. latter being suitably embedded in a floor [3 of a mine haulage-way l4 and over which wheeled motorless mine cars. I5 are adapted for travel, either singly or in coupled trip formation. Usually such cars are moved by electrically operated mine locomotives, particularly when the same are disposed in train formation, that is trips composed of a considerable number of cars. Where a smaller number of cars is needed, as inoperationsin a mine taking place adjacent to working drifts, the services of a mine locomotive are not required and it is customary to employ track-mounted mechanisms known as car feeders or car hauls, whereby to move the smaller number of cars along the trackway. As previously stated, it is the purpose of the present invention to provide an improved feeder for such uses.
In accordance with the present invention the feeder, which is designated in its entirety by the letter F, embodies a frame structure composed advantageously of a bedplate l6 which is adapted to be placed on the upper surfaces of the ties I2 between and in parallel relationship with the rails II. The plate is of a suitable length, somewhat greater than that of a standard mine car, but its proportions are limited so that it may be placed on a car for transportation in a mine from one working location to another. The plate is reinforced and rigidified by the employment of U- shaped channel beams H which are laid longitudinally on the upper surface of the plate and suitably secured thereto, the beams being arranged on their side flanges in engagement with the plate in cooperative pairs, forming guides, indicated at l8 and [9, for the reception and confinement of slidable car-propelling detents 29.
Each of these detents comprises an outer frame 2| formed with an opening 22 in which the weighted body 23 of the detent proper is adapted to be arranged in a substantially horizontal plane. The body of each detent is pivoted, as at 24, to its associated frame for tilting movement on the part of the detent about a substantially horizontal axis. Above the axis 24, the body of the detent terminates in an upwardly and angularly directed finger 25 which is disposed for engagement with a beam, lug or bracket 26 stationarily carried by and depending from the body of a mine car operated on the trackway.
To impart movement to the detents so that the same may be used alternately in effecting the advance of a trip of cars over the trackway in a single direction, the ends of the frames 2| of said detents are formed with ears 2! which receive pins 28 employed in uniting the ends of a link chain 29 with said detent frames. The opposite runs of the chain 29 are disposed in the same horizontal plane so that but little room or vertical space is required to receive the going and return runs of the chain; in fact, the height of the detent channels or guides I1 is sufficient for this purpose.
One end of the chain 29 passes around an idler guide 30 which is employed to take up slack in the chain, and for this reason includes a clevis 3| having a threaded stem-32 which passes through an opening formed in the transverse endplate 33 of the feeder frame, the outer end of the stem being equipped with a nut or the like 34 to adjust the clevis 3| and the guide 30 to maintain the desired operating position of the latter and appropriate tension on the chain.
At the end of the feeder frame opposite to the idler guide 30, the feeder frame includes a separable boxing 35 which extends below the horizontal plane 6 of the bedplate l6 and laterally or perpendicular with respect thereto. In longitudinal alignment with the bedplate the boxing 35 carries a saddle casting 36 which is formed with an upstanding hollow stud 31 for the reception of the hub 38 of a chain-driving sprocket 39. The detent-carrying chain 29 passes at one end around the sprocket 39 and is adapted to be driven by the rotation of the sprocket.
Such rotation may be effected conveniently by securing to the hub of the sprocket 39 an inverted bevel gear 49, shown more particularly in Figs. 3 and 4 of the drawings. The teeth of this gear mesh with those of a pinion 4| which is keyed on one end of a shaft 42 journaled in bearings 43, forming a part of the boxing 35. Since the boxing extends below the plane of the bedplate l6, a shallow pit 44 may be dug in the floor I 3 of the haulage-way to accommodate the same, as indicated in Fig. 3.
At its outer end and laterally of the trackway the boxing 35a is formed to effect the support of a reversible electric motor 45. In this instance the armature shaft of the motor is provided exteriorly with a sheave 46 around which passes an endless belt 41. The lower portion of this belt passes around a sheave 48, as shown in Fig. 5, which is mounted on one end of a transverse shaft 49 journaled in a gear casing 50 carried by the end of the boxing. The shaft 49 within the casing is equipped with a worm 51 which meshes with a worm gear 52 mounted on a'shaft 53. The shaft 53 is disposed in longitudinal alignment with the shaft 42 and may be joined with the latter by means of flexible couplings 54.
In this instance the bevel gear 40 meshes with a second pinion 55, as shown more particularly in Fig. 4. The pinion 55 is arranged on a shaft 56 which is journaled, as at 51, in connection with the casting 36. The outer end of the shaft 56 carries a worm 58 meshing with the teeth of a worm gear 59, the latter being mounted on a switch shaft 60 journaled for rotation in connection with the casting 36. The shaft Bl carries a crank arm 6| which engages with the pivoted actuating finger 62 of a motorreversing switch 63, whereby following predetermined movement of the chain 29 in one direction, a distance paralleling normally the length of a mine car I5, the switch mechanism 63 is actuated to reverse the direction of movement of the chain so that the second of the propelling detents 20 may be engaged with another mine car to continue the imparting of longitudinal advancing movement to an associated trip of cars. The operation of the feeder thus becomes continuous and automatic, requiring very little manual supervision. When a given detent is pushing a trip of cars forwardly on its active or advancing stroke, the detent will be positioned as shown in Fig. 3, moving the trip of cars in the direction designated by the arrow B. During this movement the opposite detent will be moved on its inactive or retreating stroke by the chain in a. direction opposite to that of car movement. Since the detents are pivoted in this supportting frames, it is obvious that when the finger of the idle or retreating detent, during its return to a starting position, engages with an associated car bracket 26, the same tilts upwardly to move under the bracket, and then by reason, of the weighted body, drops downward so that its finger will be in a position to impart pushing or advancing movement to the car bracket or other stationary part.
The circuit 64 leading from the switch 63 to the motor 45 also includes a manually controlled switch 65 by means of which current flow to the rotor may be turned on or arrested at will.
In Fig. 7 there has been illustrated one of the operating installations of the feeder mechanism forming the present invention. As shown in this figure, the working drift or face of a coal mine includes one or more rooms 66 in which, for example, a loading machine L is shown as being arranged for moving coal from the working face into carriers. Such carriers may comprise one or more room conveyors C by means of which coal loaded by the machine L may be transferred through a cross entry E to the main haulage-way l4.- The discharge V frequent repair.
