all whom- -it' may concern:

Be it. known that I, FRANK L. Sessions, a citizen of the United States,--residing at Columbus, in the county ot' Franklin and State ot Glue, have invented certain new` and uses.

ful linprm'enients in Electric Locomotives, of which the following is a specidcation, ret erenee being had therein to the accompanying drawing.

This invention relates to improvements in electric locomotives, it being particularly adapted for use in connection with locomotives used for hauling cars in mines.

The principal object of the invention is to provide a cable-reel attachment, carried by the locomotive and operated by a movable part thereon. The cable which is Wound and unwound on the reeling mechanism att'ords a supplemental means for conducting current to the motor or motors on the locomotive when it is desired to have the locomotive leave the main tra-cle in the main enn tries' of the mine and haul cars to and from rooms leading otltrom the side entries.

ln the drawings-Figure l is a side elevation of a locomotive embodying my ii'nprove ments. Fig. 2 is a' top plan viev: of the same. Fig. 3 is a view partly in side elevation andpartly in section' ot the cable'reel. Fig. rl is a section on the line lmet, Fig. o to i3 show details. l

.in the drawings l represents th Svay over which the locomotive is adap travel.

2 indicates the traine ol" the locomotive. lt may be ot any desired styley or shape.

3, of indicate the axles ot' the locomotive raclo ted to vand el, d the front and rear track-Wheels which are secured to said axles respectively. Preferably the frame 1s yieldingly mounted upon the said axles,

' ilie motors tor driving the axles may be mounted Within the frame in any Well known manner. .F or illustration in the drawing have shown a separate motor for driving each axle. Each motor mounted at its rear end upon its respective axle and is free to swing bodily relative to the axis of the'sad axle. At. their front ends the motors are supported so as to permit their trent ends to move up and down to compensete for the anevenness of travel of the locomotive in any of the Ways now known 4tor accomplishing these results.

5 indicates a frame or support for the cable-reeling mechanism. It is secured to the iront end of the locomotive and coinprises a bottoni plate o,' the standards G, (5 and the forwardly projecting Varms 7, 7, connected. together by meansot ltransversely arranged. bars 8, 8.

9 is a reel drum shaft mounted in bearings l() l0', carried by the standards G, 67 respectively.

il is a drum or reel rigidly secured to the said sli-.itt 9 between its bearings l0, l0. Ylhe shaft 9 hollow for a. portion of its length, as shown at 9, and is adapted to receive the end 1:2 et' the flexible cable l2 'which is "wound upon tliereel.

l-leretoitore in the construction of cable reeling` devices for locomotives of this type, conside able dilliculty has been. experienced in providing means tor operating` the reel or drum so that it will properly Jpay out and wind up the cable the locomotive is moving away from or approaching the points at which the cable is connected with the electrical circuit. In payingout the cable, in order to prevent back-lashing of the reel, l have found it advisable to interpose a bralti ingmcchanism bctiven the reel and some stationary part of the locomotive, and in wint'ling up the cable l have found it particularly desirable to have the cable wound on the reel at a speed greater than the speed ot' travel ot the locomotivej so as to insure that the Wheels oi the locomotive will not run-over land mutilate the cable.

In order to accomplish the above results7 namely, oi having the reel ivind up the cable at a greater rate than the spe d of travel of the car. and pay out the cable under tension as the car moves away from thev point at which the cable is connected to the main conductor, l arrange to drive the reel shaft 'from the armature shaft. of the front motor and interposc between the armature shaft and the rcel shaft a train of oiver-transmitting drums, including therein a positive clutch and a friction clutch, he positive clutch being` adapted to operate only when the locomotive isrunning toward the paid out cable.

13 indicates the front armature shaft.

let is a pinion secured to one end thereotl find adapt-ed to mesh with a gear wheell 15 which is secured to the tront axle I3. At its other end the armature shatt l?) has mounted upon it a. sprocket or drive-wheel 16.

.17 indicates as an entirety a positive clutch of the ratchet and pawl type which is interposed between' the said sha-ft 1B and the drive-Wheel 16. This clutch 17 comprises the pawlecarrying disk 18 which is keyed toltliie :said shaft 13.

19""are spring-controlled pawls mounted on the paw] carrier and adapted to engage with the Iwalls of teeth arranged on the inner periphery of the rim of the wheel 1G. When the locomotive is traveling so as to pay out cable the armature shaft 13 revolves the pawl carrier clockwise and the pawls ride freely over the notches or teeth i'n the Wheel 16,but when thelocoinotive is run ning in the opposite direction and it is essential that thev cable should be 'wound up,y the said pawls engage with the walls of the notches in the wheel 16 and the said wheel is positively driven.

20 indicates in its entirety a friction clutch interposed between the drum shaft and. the armature shaft 13.

21 is the recessedxelement of the clutch loosely mounted on the shaft 9 immediately adjacent; to the drum l1. This element of the clutch is preferably mounted one sleeve 21a loose on the said drum shaft and is held against lateral displacement by a collar 2lb secured to the shaft. 211C indicates an oil duct in. the said clutch element Q1 through which oil may be supplied to lubricate the bearing surface between the sleeve and the drum shaft- 2l is a sprocket or drive wheel carried by the said clutch element 21 and preferably formed integral therewith.

22 is a driving belt or chain connecting the wheel`21 with the drive wheel 16 on the ariiiatu-re shaft 1S.

28 is the movable element of the friction clutch Q0. It comprises a sleeve 23 splined to the drum shaft 9 and adapted to rotate therewith and move longitudinally thereon.

It carries at its inner end the tapered fricadapted to engage with the tion plates no walls'of the recess in the clutch. element 21. 211: is a groove in the periphery of the sleeve Q3 adapted to receive the trunnions 25 of the operating yoke Q6.

The mechanism for shifting the movable clutch element 23 operating` through yolte QG comprises a bell crank lever :2T pivoted at 27 to an arin 6a carried by the standard G. This bell crank lever has one arm pivoted to the inner end of the yoke Q6, which is fulcrumed at @D on a forwardly extending ariii ofthe standard 6, and its other end pivoted to the forward end of the controlling-or shifting rod 28, which extends rearward to the opposite end of the locomotive .and is pivoted at Q8 to an operating liaii dle 29 nioulnted on the frame of the loco motive within easy reaching distance of the operator. r

30 is a sleeve secured on the Adrinn shaft 9 outside of the clutch element it externally screw threaded to receive the dish or plate 3l which may be adjust-ed. longitw dinally of the said sleeve.

32 indicates springs situated in recesses 33 vin the clutch element and bearn at their outer ends against the disk 31. T ese springs normally tend to hold the clutch element 23 in engagement with. the clutch element Qi and the pressure with wl'iieh engagementis maintained may be regulated or varied by adjusting the dish: 3i longitii dinally of the sleeve 30. 3l' are apertures in the periphery of the said disk 31 adapted to receive the Wrench for turning the said tion between the clutch elements the opi erator may increase the friction bykthrovifl ing the lever tlupward as indicated in dotted lines in Fig. l thereby imparting a downward thrust on the rod 28 and pressing the movable element 23 of the clutch more firmly into engagement With the stationary element 2l. To separate the clutch elements the lever is swung downward to substantially a horizontal posit-ion in which position the rod 28 is drawn rearwardly causing the disengaging of the clutch elenieiits. lThe stop '29h limits lthe throw of the lever 29. l

,As heretofore stated it4 is essential that means should be provided for preventing the baclolashing` of the cable as it is unwinding from the recher in other words to control the uiiwiiiding` movements of the reel. l provide such a controlling' device preferablvat the opposite side ot' the reel from the friction clinch Q0.

indicates as an entirety a friction clut'cli for controlling the unwindiiig movements of the reel.
