NILS DAVID LEVIN, 0F `COLUIVIBITS, OHIO, ASSIGNOR TO THE JEFFREY MANUFAC- TUBING COMPANY, A CORPORATION OF OHIO.
nLncrnic-Locoivio'rivn CABLE-manine MiicHAivIsivi.
To all whom t may concern.'
Be it known that I, Nus D. LnviN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Electric-Locomotive Cable-Keeling Mechanism, of which the following is a'specification, reference being had therein to the accompanying drawm Y This invention relates to electric locomotives of the type provided with reels for winding and unwinding electric conductor cables.' Locomotives of this class are now well known and are especially adapted for use in coal and similar mines to enter side entries and rooms which are not provided with trolley wires or other permanent conductors. In operation the conductor cable is secured to a trolley wire or other conductor, and current is supplied through the cable to cause the locomotive to advance into a side entry or room. As the locomotive moves forward, the cable is automatically unwound from the reel. When the locomo tive returns, current is still supplied through the cable and the cable is automatically rewound upon the reel.
The object of this invention is to provide improved actuating and controlling devices for the reel. With this object in view, the invention consists in the arrangement of parts and in the structural features which are fully set forth inthe following specification and claims.
In the accompanying drawings which forma part of the specification' I have shown those embodiments of my `invention which I now consider preferable, but it will be understood that modifications and changes may be made without departing from the spirit of my invention.
Of the drawings,
Figure lis a side elevation of a locomotive embodying one form of my invention.

Serial No. 639,931.
Fig. 6 is a plan view of the locomotive shown in Fig. 5.
Referring to the drawings, 1 represents, as a whole7 a locomotive which may be of any of the ordinary forms. The locomotive shown is provided with the usual axles and track wheels and is driven by motors 2, 2. At one end of the locomotive are the `usual controlling devices such as the brake wheel 3 and the controller 4. At the other end of the locomotive there is located the cable reel mechanism which will now be described in detail.
`Referring especially to the constructions in Figs. 1 to 4, 5 represents a main reel frame which is bolted,` or otherwise secured, to the main locomotive frame. 6 represents the reel which comprises a center 7 preferably made up of wooden disks and metallic side flanges 8,8. The parts ofthe reel are held together by means of the through bolts 9, 9. The reel center is recessed at its ends` and in the recesses are secured hubs 10 and 11 which are secured to short stub shafts l2 and 13.A `One of the stub shafts, as for in stance, 12, is mounted in a metallic bearing 14 on the frame 5; the other shaft 13 is mounted in a bearing 15 which is supported on the frame 5 by means of a block 16 of insulating material such as wood.
17 is a bracket extending horizontally from the frame 5. A Mounted upon this bracket is a motor 18. A controller 18 is provided for this motor. The motor is pro vided with a horizontal shaft 19 carrying a pinion 20. Mounted above the motor, pref erably upon the frame thereof, is a horizontal shaft 21 and a driving gear 22 which meshes with the pinion 20. Also secured to the shaft 21 is a sheave 23 adapted to receive and engage with an endless rope 24. This rope also engages with a sheave 25 secured to the end of one of the beforementioned stub shafts, as for instance 12.
Mounted in the'frame 5 below and at one side of the reel is a shaft 26 which is preferably stationary. p Pivoted near thel end of the shaft which is adjacent the sheave 25 is a lever 27 which extends diagonally upward and which carries at its upper end a pulley 28 which is arranged to engage the rope 24 to tighten it. Also pivoted upon the shaft 26 at a point adjacent the lever 27 is an upstanding arm or lever 29. At the upper end of the arin 29 is a brake shoe 30 which is arranged to engage the periphery of the sheave 25 when the arm 29 is moved. The arm 29 may be moved by means of a lug 31'1on' the lever 27 which engages with ascrew 32 which extends through a threaded aperture in a lateral projection on'the arm '29.'-By adjusting the screwT the position of the arin 29 relative to the lever 27 may be regulated.
upward extending lever 37 to the upper end of which is pivoted a yoke`38`.V The yoke 38 is provided with a threaded aperture adaptedto receive a threaded rod 39.l The rod I39extends the length ofthe locomotive and is provided at the operators end with a hand wheel 40, b means of which it can be moved longitudinally to cause thefirope to be'tightened or the brake to be applied.
Mountedin bearings on brackets 41, 41 on the frame 5 is al guide mechanism shaft 42V which is double threaded as indicated lin Fig. 4. This shaft 42 is driven from the reel by means of a chain 43 which passes overthe sprocket wheels 44 and 45. Mountedin a suitable guideway which extends parallel to the shaft 42 is a carriage 46 which is provided to engage with the double threads ofthe shaft 42 and to be moved by them backward and forward along the shaft. The carriage 46is provided with guide pulieys47, 47and 48,48. i i
The cable is led in between the guide pulleys on the carriage 46, and if provided with two" conductor wires," one of these isvconnected with the hub 10 and the other with the hub 11. From the hub 10 electrical connectionis established through the shaft 12 and the bearing 14 to the metallic parts of the locomotive and to the ground. From the hub 11 connection is established through the brush 49 to the motors 2,2 and 18.
Then it is desiredv to operatethe 4locomotive shown in Figs.\1 to 4 and to make use of the ycable reel mechanism, vthe freee'nd ofthe cable is secured to a conductor and the locomotive is caused to` move inthe usual manner away from the conductor. tiring this movement the cable is unwound from'v the reel. By meansof the 'hand wheel 40 and the rod 39,v the lever 37 and associa'ted parts are maintained in the positionshown by dotted linesin Fig. 3', The unwinding ofv the cable 'inay'be controlled b'y' vadju sting the retarding force 'of the b'r'akeshoeO to' suit the conditions. During unwinding it will be understood that the rpe'24i's`s1aek. Itis, therefore, immaterial whether or not the motor 18 be in operation during unwinding. K
` VWhen* the locomotiveis Ato Vreturn and it is desired torewind the cable, the lever 37 and` associated parts are moved by means of the hand wheel 40 and the rod 39 to the posifOn shown by full lines in Fig. 3; the result beingithat the brake shoe 30 is moved out of contact` with the sheave 25 and that the pulley 28 is lmoved into position to tighten the rope v24. As a result' ofthe tightening of the rope 24, powerfislftransmitted through it from the motor 18 to the reel 6. flhe power connection `afforded ,by` the rope is a yielding one, andas a result excessive tension on the` cable is `made impossible. AsV soon as *the cable tension reaches a definite amount the ropewll slip on one or the other of the sheaves and pre.- vent further tensioning of the cable. amount' of cable tensionv may Ybe regulated The byadjustingthe position ofthe tightener.v
pulley 28. It will, of course,` be understood thatY during winding, the cable. sguided back and forthalong the reel by means of the reciprocatingcarriage 46. v
Inl Figs. 5 and 6 I have shown va modified form ofmy invention `which differs from the form shown in Figs. 1 tov 4 in that, power for Vdriving' the reel is vderived, from the main locomotive motors instead ofv from a separate 'reel motor. .v The construction is similar t0 that I` have described with/the exception, that the 'gear 22 is mounted on a stud on the casingV of oneofthemain mor tors. `It derives fits powerfrom ,engtgmentwith an idler gear 2,2a'which meshes with a pinion 22b on the motorshaft. The motor v18 is omitted together with its controller 18a, otherwise the` construction lis Videntical with that before described,V and further description, -therefore, can be omitted. Y A
I am aware that Vrope drives for. cable reels have been heretofore proposed, and `I do not, therefore, broadly claim such Va drive as a part of my present invention.; f jIn earlier devices, use,y has been made lof the rope itself to provide a braking force 4to resist'the t rotation of the reel inv `the tunwndingv dii rection. y Thishas resulted 'in eXCeSsive wear upon theJ rope and by, my present; invention -I have provided a simple'and eie'ctiveme'ans out fixed limit into engagement with the reel sheave to increase the retardation thereof indefinitely.
