Be it known that We, JOHN E.. Gein. and IRA A. (linnn, citizens of she United Sintes, residing at Cambridge, in the county of Guernsey and Slate of Ohio, and Eyesville, in the county of Guernsey, Stale of Ohio, respectively, have invented certain new and useful Improvements in Automatic Car-Stops and @aging Apparatus for Mines; and We do hereby declare the following to be a full, clear, and exact description of kthe invention, such as Will enable others skilled in the art to which. it appertains to make and use the same,

0111' invention relates to mining appliances but has reference more particularly to automatic cer-stops and cuging-apparaius employed for elevatingy coalto the surface of mine shafts.

The object of the invention is to provide mechanismfor automatically releasing @he irstand each succeeding one or" a train of loaded cars, delivering the saine upon the floor of a mine cage, elevating it'to the surface, and finally discharging. theempy cars after they have been returned to the bottom of the "sh-aft. v

A. 'Eurher object is that of reducing ihe number'o employees required, safeguard ing Jrhe lives and limbs, or" those actually engaged in the several operations aforesaid,

and reducing operating expenses.

nJl/"ith these and other objeccs in vier.y our invention consists in certain novel featuree and in certain combinations and arrangewhieli will be liereinafer de lowing.

By ret erence to Figs. 5 and 6, more especially, it

3 will be noted that the end rail sections 15, 7 15, arehinged to platform 14 at their extreme outer ends as at 18, are connected at their inner ends b a' cross bar 19 from which depend'hea ed bolts -or tie-rods 20, connected reciprocally With a sub-frame of the cage of which a description will follow. The said bolts 2O are surrounded by coil springs 21, 21, which when compressed serve to elevate the innermost ,or free ends of rail sections 15, 15 as shown by dotted lines in Fig. 5. Then normally depressed as represented by Figs. 5, 6 and 7 the said rail sections are securely retained by a keeper 22 depending from the center of cross bar 19, and a spring-pressed horizonally slidable latch 23 carried by the underside of the licor or platform 14. To the downwardly curved tail-stoel( of said latch 23 is a horizontally and outwardly extend- 25mg operating link 24 the latter pivotally connected to a short lever 25 carried by a' rockshaft 26, also journaled beneath the cage floor, while-the opposite end of shaft 26 isvupwardly curved; or rigidly connected to a member upwardly curved in the path of a wheel traversing the adjacent track section 15, this forthe purpose of automatically withdrawing latch 23 as a car leaves and permitting the track sections to assume their dotted position for purposes which will appear in connection with a statement of operation hereinafter.

Rlgidly secured to, and downwardly extending from, the longitudinal side rails or channel irons 11, 11`` the mine cage, are

bolts 27 headed at 'their lowermost ends, upon which are reciprocally suspended a sub cage-frame of skeleton form comprisH ing longitudinally arranged side channel irons 28, 28, corresponding with the said irons 11, 11 immediately above, and reinforced by transverse connecting irons 29 bolted thereto at intervals as best shown by Figs. 5 and 6. Crossing at right angles go the said sub-frame members or irons 29 in so continuous track across said hoor.

vertical alinement with slots 17, 17 of the ,cage floor 14 and ot a length to correspond therewith, are I beams 30, 30, upon the upper surfaces whereof are secured rail sec V55 tions 31, 31 which are therefore vertically movable upon the sub-frame with relation to the cage licor, and are adapted when elevated through slots 17, 17 to register with the end sections 15, 15 and 16, 1G to make a iVhile at both sides of the mine cage downwardly projecting V shaped strut rigidly secured at its opposite endswith its inverted apex terminating at a point below the lower- (5 most or normal position of the sub-frame aforesaid as shown by Fig. 2. At their lowermost points these struts are connected by a cross bar 33 upon which is mounted an. enlar ed sleeve 34 for purposes hereinafter statedi. .f

Leading to the mine shaft so as to regisl ter at times with the tracks aforesaid upon the elevator cage floors are a pair of tracks 35, 35 and 36, 36 of ordinary construction but slightly inclined toward the sump. At a given point upon each track 35 and 36 approximately one car length from the sump are located ear stops of novel construction and operation, these also being coun-- terparts one of the other and adapted to the first ear of a train previous to caging same. These stops of which but one will be described, comprise a main rod or bar 37 having an adjusting nut 38 upon the lower end swiveled upon one of the ordinary track crossties, as best shown by Fig. 9. Upon said rod 37 is reciprocally mounted a hollow body member or vstop-block 39 having an upwardly projecting WedgeLshaped spur 40 for engaging, at times, the advance bumper of a coal caras shown by Fig. 2, while in terposed between the lower end of said block 39 and an adjusting nut 41 threaded upon the upper end of bar 37 is an absorption spring 42 tor reducing the shock when a car is suddenly arrested. To the uppermost portion of the said stop-block 39 and upon each side thereof are pivotally connected a double toggle lever 43, 43 .having their opposite or lower ends keyed upon a rock shaft 44, and' so positioned that the links of said toggles slightly pass their centers of attachment when elevated, as shown by full lines. To both ends of said shaft 44 are also securely keyed o icrating levers 45, 45, from the free ends otIL which in a, horizontal direction project pivotally connected rods 46, 46 which at their opposite ends are again pavotA ally connected to bell-crank levers 47, 47 journaled as at 48 in lixed supports or journal bearings upon opposite sidesof the track as indicated by Fig. 1` of the drawings. llt will thus be seen that the'shorter members of the said bell-crank levers are located upon the inside, adjacent to the track rails, and in a 'position to be engaged by th wheels of a passin 'car to rock said levers' upon their pivota supports.

Upon the same pivots Aor wrist pins 49, which serve to connect the upper end ot levers 47 and theircnperatiug rods 4G as aforesaid, are slidably secured links 50 ter initiating in horizontal rods 51 leading to an upright 52 at one side of the elevator or cage shaft. As best illustrated by Figs. 1 and 2 thc-said rods 51 at their-'outer ends are pivotally connected to the lower extremity of'` a T shaped tripper-or operating member 53,-' which inturn is pivotully connected, as dai curely spiked l ,delivery t0 the mine or enges, an
