MOTOR.

SPECIFICATION forming part of Letters Patent No. 733,217, dated July 7, 190e. Application iled October 21,1902. Serial No. l28,l66. (No model.)

T0 all whom, it may concern:

Be it known that I, ULvssEs S. KING, a citi-4 zen of the United States, residing at Cherokee, in the county of Crawford and State of Kansas, have invented new and useful Improvements in Motors, of which the following is a specification.

rlhis invention relates to a motor for use exclusively underground in mines and the like and one purpose of the same is to provide a compact and efficient device of this classwhich can be easily controlled and capable of drawing a heavy load.

A further purpose of the improvement is to so shape the motor that it will not interfere with mine-lead structures and will easily pass through the latter without requiring a change in the usual arrangement in contradistinction to motors having a cumbersome construction and obstructive lateral or other projections.

A further purpose of the improvement is to introduce in a device of this class a form of drive-gearing for the axles which will obviate any tendency to lost motion and capable of reversal to drive the motor in either direction, the gear being of such nature and the entire motorhaving such weight as to cause the latter to remain in tractive conjunction with rails,

the said gearing positively actuating the mo tor through the operation of the driving medium embodied therein.

A still further purpose of the invention is to equip an underground motor with such detail accessories as to render it convenient in operation, strong and durable, and comparatively inexpensive in the cost of manufacture.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

ln the drawings, Figure lis a side elevation of an underground motor embodying the fea-v tures of the invention. Fig. 2 is a top plan view of the same. Fig. 5 is a horizontal section taken in a plane below the engine or driving medium proper and showing parts of the clutch mechanism broken away. Fig. et is an end elevation of the motor. Fig. 5 is a longitudinal vertical section. Fig. 6 is a transverse vertical section on the line G 6, Fig. 3. Fig. 7 is a longitudinal vertical section on the line 7 7, Fig. 3.

Y to one end of the motor.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral l designates a truck-frame comprising side and end bars or beams securely bolted or otherwise fastened together. In the complete organization of this frame it will be provided with bumpers or buffers and coupling means whereby either end of the motor may be attached to the ears. The side bars of the frame will also be supplied with suitable bearings or journal-boxes 2, in which the terminal journals or axles 3 are rotatably mounted, the said axles having flanged wheels 4 thereon of the usual construction to engage track-rails. ln the frame l is a basket 5, which depends approximately on a level with the lower edges of the side and end bars or beams of the said frame and is bolted at its upper portion to lugs or projections on the side bars or beams, the latter having portions thereof projected at a greater elevation than the level of the upper edges of the end bars. This precise form of the frame is notessential, however, and maybe varied at will to meetcertain changes in construction of the motor that may be demanded to accommodate certain contingencies. The frame and the motor-journal, however, will be of such structure as to adapt it for general underground use without modification, except possibly in the proportions and minor detail accessories. The journal-boxes 2 are disposed in vertical slots 6 in the side bars Or beams of r the frame, and between the upper edges of the said boxes and outwardly-projecting caps '7 cushion-springs 8 are interposed, as in the usual car structures. On the axles 3 are spur-gears 9, meshing with an intermediate idler spur-gear l0, journaled on a stub-shaft ll, extending inwardly from one of the side bars or beams of the frame l, as clearly shown by Fig. The gears 9 and idler-gear 10 are held in continual mesh, and also meshing with one of the gears 9 is a motion-transferring pinion 12, journaled on a stub-shaft 13, also extending inwardly from one side beam of the frame l and of itself maintained in continual mesh with a drive-pinion la on a counter-shaft l5, having bearing at opposite ends in the side beams of the frame adjacent On the countershaft 15 are clutch devices 1 G, including bevelgears 17, so disposed as to operate the counter-shaft in opposite directions to control a reversal of movement of the motor and which will be more fully hereinafter explained in detail.

Suitably disposed on the upper portion of the basket 5 is a gasolene-motor of a threecylinder type, the several cylinders of this engine concentrating their driving force on a single driving-shaft 18. The advantage of the three-cylinder type of gasolene-engine, which will not be herein specifically described, is an increased explosive force with a more positive actuation and regularity in the rotation or operation of the driving-shaft 18, the latter having on opposite ends balance-wheels 19 for obvious purposes and at one end provided with a bevel-pinion 2O in such position between the bevel-gears 17 on the countershaft 15 that either of the said gears maybe quickly thrown into engagement with or adjusted in inoperative relation to the said bevel-pinion 20. Many forms of clutch devices may be used to arrive at the results sought; but it is obvious that means must be provided for positively actuating said friction devices or clutch mechanisms to quickly and positively control the direction of movement of the motor. One of the preferred forms of operating' devices for shifting the clutch devices comprises a rock lever or rod 21, journaled or applied to the under part of the frame 1, to one side of the center, as clearly shown by Fig. 3, and having an operatinglever 22 attached thereto and extending upwardly through the frame within convenient reaching distance of the engineer or motorman. Rising' from one extremity of the rock lever or rod 21 is an angular shiftingarm 23, having its upper end projected inwardly over the frame, at one extremity of the latter, and attached to a slide-bar 24, mounted in suitable bearings or boxes 25 at one end of the frame, or that adjacent to the countershaft 15. The slide-rod 24 is disposed in a plane at right angles to the rock lever or rod 2l and has inwardly-extending shifting-arms 26 secured thereto and embracing circumferentially grooved ends of clutch sleeves 27, slidable on the counter-shaft 15 and engaging a spline 28, proj ecting from the shaft, to rotate with the latter.

The gears 17 have outer tubular bodies 29 or contact members, with which expansible clutch members 30 are adapted to engage, and each comprises a hub 31, engaging the spline 28 adjacent thereto and having a clutch-rim of such normal diameter as to fit within the tubular body or contact member 29 of each gear 17. It will be understood that the gear 17 and its tubular body or Contact member 29 in each instance is loose on the countershaft, and when the rim 32 cooperating therewith is in normal condition the shaft 15 will not be affected by either gear so far as rotation is concerned until the rim 32 is expanded to create a frictional bind thereof against the inner surface of the tubular body or contact member 29. rIhe spline 28 which is used in connection with each clutch device is long enough to compensate for longitudinal adjustment of each clutch device on the shaft 15 through the medium of the arms 26 and the devices controllingthe latter. On the hub 31 of each rim 32, at a point diametrically opposite and above the spline 28 of the shaft 15, an expanding-lever 33 is pivotally secured and extends outwardly and upwardly and is movably attached by means of an upper joint 34 through the upper terminal of the screw 35 and a buckle 36, which includes a central nut 37,the lower terminal of the screw 35 being secured by means of a knuckle-joint 38 in a recess at the inner extremity of the upper part of the sleeve 37. The expanding-lever, adjacent to its pivotal point on the hub 31, has a fulcrum-block 39 mounted therein, each expanding-lever consisting of two members, as clearly shown by Fig. 7, and the fulcrumblock provided with opposite trunnions 40 to engage said members. Adjustably rising from the fulcrum-block 39 is a screw post or shank 41, having a wedge-block 42 secured on the upper end thereof, with a guide-pin 43 rising vertically from the center thereof. The wedge-block 42 is held in line and partial engagement with the spaced terminals of the rim 32, and saidblock is adapted to be forcefully pushed upwardly between the ends of the rim to expand the latter and create a frictional bind between the outer surface of the said rim and the inner surface of the tubular body or contact member 29 of the gear 17. To insure a reliable and positive operation of the wedgeblock at all times in relation to the spaced ends of the rim 32, the guide-pin 43 is employed and moves in seinicircular grooves 44 at the centers of the said spaced ends of the rim. In the primary adjustment of the parts of each clutch device the wedge-block 42 is raised high enough to always occupy an operative position in relation to the spaced ends of the rim 32 through the medium of the screw post or shank 41, and through the use of the fulcrum-block 39 the wedge-block throughout its full length is caused to fully engage the spaced ends of the rim irrespective of the angular position of the expanding-lever with relation to the hub 31. It is obvious that more or less wear will ensue on the rim 32 in consequence of continued use, and if nothing IIO were provided to compensate for such wear the positive operation of each clutch device would soon become impaired, but through the medium of the turnbuckle 3G the expanding-lever 33 can be easily adjusted when necessary to compensate for wear on the rim, and thereby always insure a positive engagement of said rim with the inner surface of the tubular body or contact member 29 of the gear 17. It will be understood that each clutch device is duplicate in construction, and the shaft 15 has two splines 28, so that the actuation of the shaft by the individual clutch devices may be independent. lVhen the slidebar 2i is shifted in opposite directions to operate either one of the clutch devices in accordance with the direction it is desired the motor shall move, the clutch device shifted on the shaft will be thrown into engagement with the pinion 2O on the shaft 1S through the medium of the gear 17 of said clutch device, and when the sleeve 27 is shifted and mesh of the operated gear 17 with the bevelpinion 2O is obtained the resistance to further movement of the said clutch device will cause the expanding-lever to be thrown outwardly and force the wed ge-block 4:2 between the spaced ends of the rim 32, and thus transmit motion from the shaft 1S to the gear 2O and operated clutch device to the shaft l5 and from the latter through the drive-pinion li and motion-transmitting pinion l2 to the gears 0 on the axles S, and thus propel the motor in a positive manner. The adjustment of the slide-bar 2i in either lateral direction will be maintained by suitable retaining devices arranged adjacent the lever 22, and it will be understood that many mechanisms for this purpose could be used. To insure a tight non-slipping engagement between the rim 32 and the inner surface of the tubular body or contact member 2S), said gear is provided with a circumferential covering 45 of vuleanite iiber or other analogous material. It is required in mines and other underground tunnels or passages that a certain amount of fresh air be supplied to sustain human and animal life, and it is necessary in providing a motor for underground use to equip the same with means for preventing a devitalization or vitiation of the fresh air or in any wise contaminating the same with noxious odors or gases from the motor or to in the least diminish the quantity of air rcquired. This supply of fresh air in mines particularly is governed by local laws and must be preserved. To meet this requirement,the present improved motor is equipped with a muffler 4G, consisting of a cylinder containing water, as at 47, and extending from the engine is an exhaust-pipe i8, having a depending member i0 projecting into the mulfler near the lower or bottom portion of the cylinder. The upper portion of the cylinder i6, at a point distant from the entrance thereinto of the exhaust-pipe, is an outlet 50,

as clearl i shown b f Fic'. 2 and the o'ases orA noxious odors are conveyed by the said pipe 4S from the en gine to the muffler and absorbed by the water, and what steam that is in excess of the absorption or condensation, particularly after the water in the muffler becomes heated, escapes through the outlet 50 without carrying therewith any of the gases or odors from the engine due to the explosions, and thus contamination of or injury to the fresh-air supply within a mine lead or passage is prevented and the fresh-air supply remains unimpaired.

From the foregoing it will be perceived that the improved motor is constructed to meet the various contingencies and conditions existing in underground passages ormineleads without requiring a modication or adaptation of the framing structure within said leads or passages. The gearing in connection with the axles is of a strong and durable nature, and the weight of the entire motor will be such that'on a dry track or trackrails in view of certain resistance it will cause the wheels on the axles to slip on the rails with obvious advantages in motor or locomotive device constructions, as will be readily appreciated by those skilled in the art. Moreover,itisproposed to proportion the motor in such manner as to permit the use of a broader-gage track than is ordinarily employed in underground motors, with a resultant stability and greater efciency in the movement of the motor, particularly in drawing heavy loads. The motor is also constructed with maximum strength in view, and it is intended to incorporate therein as a part of its organization motive mechanism of compact form with increased power having advantageous speed qualifications and which is derived from the employment of a triple-cylinder type of engine.

Having thus fully described the invention, what is claimed as new isl.
