To all whom it may concern:
Be it known that L DUDLEY T. FISHER, a citizen of the United States, residing at Columbus, in the county ofFranklin and State of Ohio, have invented certain new and-useful Improvements in Cable-Reelsfor Haulage Mechanism, of which the following is a specification, reference being had therein to the accompanying drawing.
This inventlon relates to improvements in draft or haulage mechanism for electriclo comotives of the sort employedfor pulllng from one point to another cars which'are not provided with their own engines ormotors. For example, in coal mines relatively small cars are used which, while being loaded are separated from each "other and" scat tered over more or less of the mine, one in oneroom or at one loading point andothcrs at others. The older plan, where animal power was used, was to hauleach of these cars singly by an animal from the room, after it had been loaded, to a collecting point where a number of the cars were coupled together to form a train ory tripi Since the introduction of electric power use has been made for this purpose of gathering locomotives, each having a reel with an electric cable thereon, the terminal of which can be connected electrically to a currentsupplying wire, so that as the car moves away from the source of supply, the cable on the reel will maintain a continuity of electric conductors to the motor. In using this apparatus, the locomotive is itself run into the rooms successively and coupled to the isolated loaded cars and thereafter hauls these to the gathering point. Under many circumstances these gathering locomotlves with cable reels cannotjbe used to advan tage, particularly where the mine roof is;
fastened by a key 4 to this base in such a way that it is held firmly against rotation.
low or wherethe track has been hastily constructed, as the branch tracks frequently are which extend from the entry into the room.
The present invention relates to an apparatus adapted to be attached to an ordinary locomotive and of such nature that the locomotive can remain in the, entry or at some distant point and yet the loaded car can be hauled by power toward it while it remains stationary.
The object of the invention is to provide improved structural features and an improved arrangement of parts. I V
A further object is to provide improved friction lining 5 betweenyit and this resting upon the base 3.

Fig. 8 is a view showing the reel and a its power transmitting devices, in vertical central section and showing an electric motor partly in outlineand partly in section. Fig, 41s a side'elevation of the motor'and reel. Fig. 5 is a horizontal section on the line n w, Fig. 3. i
A indicates a car, an electric locomotive of the kind used in coal mines being selected for thepurpose of illustration Its wheels Bare fitted to the'track railsi Its body is formed of a heavy cast frame having the side parts C, C and the end connecting parts D, D. Many of the parts of the car or 1000- [motive are indicated conventionally by dotted lines. At E the electric motor is situatedin the spacebetween the twoaxles b, b This motor is geared toone of the axles in any suitable way, and by preference the aXles are geared together or connected by chains and sprockets. At F there is a chamber orspace left for the motorman and for the parts which he is called upon to manipulate frequently, such as the wheel of the controller at G and the hand wheel of the brake mechanism at At the end ofthe locomotive opposite to that where the motorman is placed I arrange a reel forthe haulage cable. This is indicated by 1 and ismounted on a vertically arranged shaft 2. This shaft is secured to a base 3 which is in the form of a strong barextending across from one of the side elements C of the car body to the other, and firmly bolted thereto. The shaft 2 is The reel 1 can rotate loosely and freely around this shaft when it is disengaged from theother parts. The reel has an antithe shaft 2,
16 indicates a hublike part for the reel or sleeve is secured, or with it is formed a gear wheel9.- e a a p 11 is a spur gear wheel mounted loosely on the shaft2 above the reel hub. This gear wheel ll is of a slightly larger diameter than the wheel 9, and has one more tooth, for a purpose to be described. With this wheel are combined devices for looking it to the shaft 2 and holding it stationary. To accomplish this the wheel itself may be provided with a clutch-element, preferably by formingjaws or teeth 24L upon its upper side. With this clutch-element a mow able element such as a pin or cross-bar 18 can engage, it extending through slots 19 in the shaft ;2 and being. movable into and out of engagement with the jaws or teeth 24:. To so move it,.use ismade'of the rod 21 connected to the clutch pin 18 and extending downward through the shaft 2. At the lower end the rod is connected to a belllever 22 from which there extends an operating rod 23 to the motormans end of the car.
i The shaft 2, at its upper end, supports the field frame 25 of the motor 8. The armature 26 is supported by the collar 6 on the shaft 2 and revolves freely on suitable antifriction bearings.
15 is a sleeve or cylinder secured to the under-side of the armature-and extending downward therefrom. From the cylinder there extend still farther downward arms 27, which, at their lower ends carry a ring 28 concentric with the shaft 2. This ring is formed with a number of bearings 29 andin each of these is mounted a shaft 12.
7 Each shaft 12 carries two pinions 13 and 1 1.
These pinio-ns differ slightly in size, the upper one having the smaller diameter, but have the same number of teeth. The pin 1. ions 13 mesh with the wheel 11, and those at 14 mesh'with the wheel 9. When the ar mature is revolved the pinion shafts 12 are rotated bodily around the shaft 2 and if the wheel 11 is stationary, that is, locked to the shaft 2, it will be seen that rotary motion will be transmitted from the armature to the reel and that the speed of. the latter will be greatly reduced relativeto that of the former.
The gear chamber inside of the cylindrical part of the reel is closed at the top by the flange 30 on the cylinder 15, and by the cover plate 31 secured to the top of the reel. This chamber can be filled with oil and perfect lubrication of the relatively moving surfaces can be effected. The haulage cable 32 may be taken off from the reel 1 at any angle but I prefer to pass it over vertical and horizontal guide rollers 33, 34 and thence to the opposite end of the locomotive where I provideguide sheaves,'35, 36, which permit said cable to be taken off for draft purposes at a great variety of angles.
Thevmanner of using an apparatus of the kind above described will be readily understood. The locomotive is stopped in the mine entry in such position that the motorman can look through the passage-way of the mouth into the room. His assistant, the trip-rider takes the end of the cable and carries it into the room and couples it to the car to be drawn out. The motorman first by the draw-rod 23 and the rod 21 disengages the clutch-pin 18 from clutch-jaws 24 allowing the reel to freely rotate. After the end of the cable is coupled to the car the motorman can, by means of the rod 23 and the rod 21, thrust the clutch pin 18 into engagement with the gear wheel 11. He then startsthe motor 8 and the reel is caused to wind up the cable and draw the car from the room to the track in the entry. When a loaded car is sufliciently close to the locomotive the latter is set in motion by means of its motor E and the loaded car is drawn to the point where the trains or trips of several cars are made up.
I do not herein claim the arrangement of themotor, the reel and the cable guide devices with respect to the locomotive as a whole as these features are presented and claimed in my co-pending application for locomotives with haulage cable mechanisms,
