Application led December 30, 1968. Serial No. 469,980.

To all whom 'it moz/y concern:

Be it knovvn that I, JoirN M. RoAN, a citi zen of the United States, residing at Dante, in the county of Russell and State of Virginia, have invented certain new and uaeful Improvements in Haulage-Locomotives, of which the following' is a specilication.

My invention relates to improvements in l'iaulage locomotives of that class which are used in mines and has particular relation to the improvement of the construction shown in my former United States Patent #851,837, issued under date of April 30, 1907.

The objects of my invention are to provide a gathering locomotive of the type set forth, of improved construction and arrangement of parts, by means of which mine cars from the various entries or passages of a mine may be readily drawn into the main enti;Y and assembled therein; to provide improved means for throwing` into and out of operation the various moving parts of .my device; to so locate and arrange the various parts of the machine, as to facilitate the convenient and ready operation there of; to provide improved means for in'iparting a Winding; operation to the electric cable carrying reel; to provide improved means in connection. With the electric cable reel for relieving` said cable of undue strain and preventingl the breaking` of the same, and to produce other improvements, the details of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of my improved gathering locomotive, Fig. 2 is a plan vieu', Figi; 2A is a detail view in elevation of one of the outer end portions of the electric cable reel shaft, Fig. 3 is a central longitudinal section of the machine on line of Fig. Q, Fig. lis a transverse section on line g/-y/ of Fig'. 1, Fig. 5 is a rear end view of the machine, Fig'. 6 is a plan view of one end of the machine with the electric cable reel and its support-ing plate removed, F ig. 7 is a central vertical section on line a-a of Fig. 6, Fig. 8 is a transverse section on line b-b of Fig. 7, Fig. 9 is a sectional view on line c-c of F ig. 11, Fig. 10 is a detail side elevation of one of the clutch raising arms which are employed in connection with the haulage reel, and Fig. 11 is a View in elevation of the clutch mechanism which I employ in connection with said haulage reel.

Sin'iilar numerals refer to similar parts throughoutv the several views.

As indicated by the drawings, I employ the usual or a desirable form of locomotive body or frame 1, which is transversely recessed on its underside in the usual manner to provide locomotive tack Wheel spaces, said body being supported upon the usual form of track wheels 2 which are adapted to run upon the rails 3 of a main track. At the center of the frame and in the upper portion thereof, I provide a transversely arranged electric motor of suitable construction ivhich is indicated at L1, which is inclosed in a suitable housing` 5 which is integral with the frame and in which is mounted rotatably, the armature shaft 6, the latter being at right angles with the length of the locomotive body. At the rear end of the body or frame of the locomotive, I provide a suitable form of electric controller 7 near which is conveniently arranged the operators seat 8.

9 represents a suitable trolley pole which is connected ivitli the motor in the usual manner and the trolley Wheel 9qu of which is adapted to run against a trolley Wire 10. Below and parallel with the armature shaft, is journaled in the framework a shaft 11. This shaft 11 carries near the center of its length a pinion 12. the latter gearing with a gear Wheel 13, which is carried on a short journaled shaft 14- beloW the shaft 11. 15 and 16 represent the front and rear Wheel axles on which the track Wheels 2 are carried. Upon these axles are carried gear wheels 17 and 18, the teeth of which mesh with those of the `@gear Wheel 13 which is arranged between said axle gear Wheels.

Upon one end of the armature shaft 6 is carried a pinion Wheel 19, the teeth of Which mesh with those of a gea-r Wheel 20 which is slidablymounted upon the shaft 11. This gear wheel 2O is provided with a central inwardly projecting` sleeve-like hub or clutch member 21 having1 the usual clutch projections which are adapted to engage a. fixed clutch member 22 of the usual er any Well known form, carried by the shaft 11. The gear'vvheel 20 is also formed With an outwardly projecting central tubular eX tension 23 With Which are connected at opposite points on said extension, the yoke arms 24 of a forwardly extending lever 24., which lever is connected at its outer end with the upper end portion of a vertical rod or shaft 25, which is journaled in a vertical bracket 26 projecting from the frame of the machine. At its upper end the rod 25 is provided with a laterally e.\'- tending arm 25a which in turn is pivotally connected with a rearwardly extending rod 27, said rod at its rear end being pivotally connected with one arm of a pivoted bell crank 28, the remaining arm of which is connected by means of a rod 29 with a second pivoted bell crank 30 which througl'i an arm 31 is jointedly connected with a pivoted operating lever 32 at the rear of the machine. This lever 32 which is pivoted at its lower'end as indicated at 32, is preferably provided with a pivoted dog 33 which is adapted to engage the desired notch of a curved fixed rack 34. The parts just described and indicated by the numerals 21, 25a and 27 to 31, are best shown in dotted lines in Fig. 2 of the drawing.

` Un the outer side of the gear wheel 2O and on the shaft 11 is loosely mounted a gear wheel 35, which is provided with an inwardlv projecting sleeve-like hub 35a which entendus within the outwardly projecting hub member of the gear wheel 2O and is slidably connected with said hub member by a key connection indicated at 35b in Fig. 9. The gear wheel 35 is in the nature of a bevel gear wheel and has its teeth meshing with those of a bevel pinion 3G which is carried on the rear end of an inclined forwardly extendingI shaft 37. The pinion 3G is formed with a collar-like extension 36a, which extension, together with the pinion, is slidably keyed on said shaft 37. With the pinion collar 36a are connected the yoke arms of a lever 38 shown more clearly in dotted lilies in Fig. 2 of the drawing, said lever being connected with the lower end of a vertically journaled shaft 39 from the upper end of which extends laterally an arm 40 with which is jointedly connected the forward end of a rearwardly extending operating rod 41 (see Figs. 9 and 2). The operatingl rod 11 is connected with an operating lever 312 at the rear of the machine, through the medium of bell crank and rod connections corre sponding to those indicated at 28, 29, 30 and 31, the rod corresponding with the rod 29 being indicated at L13 in Fig, 3 of the drawing, and the rod corresponding with the rod 3l being indicated in said ligure at 4st. The forward and upper end of the shaft. 37 carries a bevel pinion 45 which meshes with a bevel gear wheel L16 which is loosely mounted on a transverse horizontal reel carrying shaft 47, the latter being journaled at the front of the machine, as shown. The shaft 47 is provided on its outer end with a head or enlargement 17TL between which and the bevel gear wheel l() is interposed a coiled spring 4:8. The bevel wheel 4G has projecting from ils inner face a friction hub 11:0 which is preferably serrated or formed. with shallow teeth or corrugations and which through the spring L18 is normally held in frictional engagement with a collar i9 which is carried on the shaft 4&7. This shaft 117 carries between its bearings a suitable form oil reeltl on which is adapted to be wound an electric current. conducting cable 51, which leads rearwardly from said reel between and in contact with pivoted guide rollers 52 on the machine frame7 to the trolley wire 10 with which it is connected at a suitable point. f

53 represents an inclined journaled shaft which has its rear end port-ion 1^ rovided with a beveled pinion 54 which, together with a collar extension 54a is keyed slidably upon said shaft 53, said collar hat having connected therewith the yoke arm projections 55 of a vertically jonrnaled shaft shown in dotted lines at 56 in Fig. 9 o-f the drawing. Vith the upper end of this shaft 5G is connected an operating rod 57 which through the medium of rod and bell crank connections which run beneath the connections to the lever 42 is connected with a pivoted operating lever' 5S at the front of the machine. On the forward end of the shaft. 53 is carried a beveled pinion wheel 59 which meshes with a bevel pinion 60 carried on the upper end of a vertical rotatably mounted shaft G1 (see Fig. 7 which at its lower end earries a pinion wheel 62. This pinion G2 meshes with a gear wheel G3 which is rotatably mounted on the lower end of a'vertical reel shaft G4 which has its lower portion supported in a horizontal member of the frame 1 and which has its upper end supported in the outer end of a horizontal plate or bracket G5 which projects from a suitable portion of the frame or body 1. Upon the shaft GJC rotatably mounted the central vertical tubular member G6 of a spool or reel body (S9. As shown, the lower end of the reel sie-eve G6 bears upon the up-per side of the hub of the gear wheel (i3 and surrounding said bearing parts and keved in connection with the reel member G is a vertically slidable sleeve G7 with which are connected at opposite points through the medium of an external b and .68 and projecting pins (38a as indicated in Fig. 8 of the drawing, the outer ends of parallel arms 69 which are rigidly connected at their remaining ends with a horizontal rocker shaft. 7() which is suitably pivoted at each end. This rocker shaft is provided near one end with an arm 71 with which is connected the forward end of a rod 72, the latter extending rearwardly as indicated more clearly in Fig. 3, to the rear portion of the machine, at which point it is pivotally connected with ies a pivoted operatiiig lever 73. Upon the up per side ot' the outer end of cach oft the arms ttl) is lorined a cani-like projection 711-, which when the sha'lt 7() is rocked, are designed to contact with the ul'ulersidc o't the reel body (56.

)is shown more clearly in Fig. 1l oit the drawing, the lower portion oit the sleeve (3T is formed on its underside with clutch projections 6T which normally engage clutch recesses or clutch members titl@ in the upper side o't the hub of the wheel (3?), thereby pro vidiug means for interlocking the reel (3G and the gear wheel (t3. The. reel (36 is de* signed to have wound thereon a suitable steel haulage cable which runs from said reel forwardly over the desired one ot a plurality of pulleys 7G which are journaled at the Jfront end of the body. On the outer end ot thc shaft 11 is carried a brake wheel TT about which is provided a brake band or flexible brake member 7S. One end of this brake band is connected with a bracket T9 which projects from the side ot the machine frame and the other end thereol' connected with a collar 8() which is slidably mounted on a bolt or threaded pin 81, the upper end of which is pivotally connected with a block 82 which in turn is pivoted in the bracke 79. On the lower end ot the bolt or pin S1 is carried a nut 83 against which said collar is adapted to bear. Journaled in the machine frame and in the outer member of the bracket 7) is a short horizontal shaft Sil which forms the pivot for the block 82 (see Fig. Il) and with which one end of the brake band 7S is connected. On the inner end of the shaft S4 is carried an arm S5 with which is connected a rearwardly extending rod SG, the latter running to the rear of the machine and connecting with an operating lever 87.

I will now proceed to describe the opera.- tion of the heroinbet'ore described locomotive: It will be understood that gathering locomotives of this class, are ordinarily employed in the main entries of mines and in order to produce a traveling motion ot the entire locomotive upon the track rails 3, the motor is set in operation by a ].irelin1ina11y operation of the coi'itroller 7, with the result that through the gear connections described, with the gear wheels 18 and 17, the desired rotary motion is imparted to the track wheels 2. In order to provide a means for reversing the direction of the travel ot the locomotive on the tracks7 I have provided a suitable current reversing means which is controlled by a lever indicated at SS. Assuming now that the locomotive has been run to a point opposite a side entry, from which it is desired to draw one or more cars into the main ent-ry for the purpose of assembling the same therein, the gears which control the ground wheels, are first thrown out ol." action by an outward n'iovel'ncnt ot the lever 32 shown at Fig. 2, which through the connections described, results in i'noving thc gear wheel 20 outward until its clutch projection il is disengaged from thc clutch member ln the construction ot' the gear wheel 2t), however, it will be observed thatthe width otl thel teeth thereof is such as to retain said gear teeth in connection with the teeth ot the pinion 15), alter the clutch niembers have been (ilisengaged as described, thus providing tor a continued revolution oli the wheel 20 after the motion ot the track wheel controlling gears has been disconthiued. lt will be seen that the motion of wheel 2O is always imparted to the bevel gear wheel 3:3, so that by means'o't the bevel pinionsl and the two shafts connected with thisl gear, one reel or the other, or both, can be driven trom the motor, the direction ot' drive being de pendent upon the direction ot revolution ot the motor. By pulling outward on the brake lever S7, the locomotive track wheels will be held against rotation` owing to the tact that through the connections described, a suliicient rotary i'noveinent is imparted to the shaft 8l- (see Fig. il) to cause an upward pull on the block 82 and threaded piu S1 which in turn will cause a binding of the brake band 78 against the periphery ot the brake wheels 7T, and prevent said brake wheel, together with the track wheels with which said brake wheel is geared, from rotation. There being no necessity for the en'iployinent oli the electric cable 51 or its reel, the latter is thrown out ot operative connection with the motor by moving the lever l2 outward and through the connections described, which connections include the rod 41, shaft 3S) and yoke 38, the bevel pinion 36 is thus caused to slide outward on the shaft 37 until out of gear connection with the wheel 35 (see Fig. 9). It will be understood that in order to connect the haulage rope or cable T5 with a car to be drawn into the main entry, it will be first necessary to unwind said cable from the reel ('16 and in order to permit of this unwinding movement, the lever 73 shown in Fig. 8, is pulled outward, resulting through the rearward pull on the rod 72, in turning the shaft 70 until through thc lifting movement of the arms (39 (Figs. 7 and S) the clutch sleeve ($7 is lifted out of engagement with the hub of the whe-el G3, thus disconnecting said reel from said rotating wheel and permitting a paying out ot the haulage cable which is on the reel. rthe cable being attached to the car to be drawn from a side entry, the shaft '70 is again rocked to cause a clutch engagement of the sleeve member G7 with the wheel G3, which through the rotation of said wheel, will result in the reel being properly rotated to wind the haulage cable thereon, thereby drawing the ear from its position in the side entry to a position in the main entry.

In the operation of payingl out the cable and particularly in lowering a car down an inclined surface, it is 1lesirable to regulate the speed at which the cable unwinds from the reel and this I aecon'iplish by imparting a sufficient rocking action or rotation to the shaft 70 to cause the cam projections T4 of the arms (it) to press the reel upward until its upper side is in frietional or brake contact with the underside of the plate (35. It will be understood that by throwing the lever 58 outward and thereby producing a rearward pull on the rod 57 and a turning of the shaft 56, the bevel pinion 54 may be moved rearward on the rod 53 until out of engagement with the teeth of the wheel 35, thereby disconnecting the operating parts of the haulage reel from the other operating or running parts of the machine.

Assuming that it is desired to run the locomotive from the main entry into a side entry where no trolley wire is provided and consequently where no trolley pole can be employed', the current necessary for running the motor is supplied by the electric current conducting cable 5l. In order to utilize the electric cable for this purpose, it is desirable to pay out said cable from the reel 50 at the same speed at which the locomotive is traveling on the tracks and assuming that the brake band 'T8 has been released by the inward movement of the. lever 8T and that by the inward movement of the lever 3Q, the

` clutch member 2l of the wheel 2O is again brought into engagement with the clutch member .22 of the shaft ll to effect an operative gear connection with the track wheels, the method of transmitting motion to the electric cable reel 50, for the purpose of paying out said cable, is as follows: The bevel gear wheel 36 being in engagement with the teeth of the wheel 35, it is obvious that rotary motion will be imparted to the shaft 37, its pinion 45 and through the latter to the bevel gear wheel 46, thus imparting the desired rotary motion to the shaft of the reel 50 which will result in the paying out of the electric cable 51, thus permitting the locomotive to travel into a side entry in which no trolley wire is provided. It will be understood that when the motor is reversed for the purpose of running the locomotive to the main entry, a corresponding reversal of movement will be imparted to the reel operatmg rod 37 and to the reel shaft, thereby resulting in a winding of the electric cable upon the reel 50 at desirable speed. In case the winding strain on the cable 5l should for any cause, be increased to such an extent as to create a liability of breaking said cable, it will be understood that the tendency of the reelshaft to revolve at a greater speed, will be sullicient to release the frictional engagement; of the members 4GiL and 49, thus temporarily relieving the strain, after which said members will again come into operative engagpgement through pressure of the spring 48.

From the const ruction and operation which .l ha \'e (fleseribed, it will be observed that improved means are provided for producing a positive operation of the various parts of my device and that the operationlof collecting and distributing cars in a mine, is adapted by my .improved locomotive to be accomplished in a rapid and convenient manner. It will be seen that two .separate reels, a haulage reel and a conductor reel, are provided these reels being capable of being independentlfyY driven by the clutches and gearing described, from the motor which drives the car,

lh-at I claim, is:

l. In a haulage locomotive, a motor,means for trai'isn'iitting motion from the motor to the locomotive, a reel, a haulage cable carried by the reel, means for transmitting motion from the motor to said haulage cable reel, a second rotatably mounted reel, an electric current conducting cable carried on said second reel, and means for transmitting motion from the motor to said electric cable reel in either direction.

2. In a haulage locomotive, a motor for transmitting motion from the motor to the locomotive, a reel, a haulage cable carried by said reel, a second rotatably mounted reel, and means for transmitting motion from the motor to either or both of said reels.

3. In a haulage locomotive, a motor and motor shaft, a pinion carried on the motor shaft, a main operating shaft 11, a gear wheel slidable on said main operating shaft, said gear wheel adapted to be disengaged from said operating shaft but retained in engagement with the motor shaft pinion, a reel, a haulage cable carried thereon, a gear wheel 35 loose on said. loperating shaft and having a hub engagement with said slidably mounted gear wheel, an electric cable reel and a cable carried thereon, and means whereby motion may be transmitted through the rotation of said sliding gear wheel and said gear wheel S5 to either or both of said reels.

In testimony whereof I aliix my signature in presence of two witnesses.
