MINE-ELEVATOR.

SPECIFICATION forming part of Iletters Patent No. 478,595, dated July 12, 1892.

Application filed March 8, 1892. $erial No. 424,186. (No model.)

To aZZ whom it may concern:

Be it known that I, STEWART HAMILTON, a citizen of the United States, residing at lVeir, in the county of Cherokee and State of Kansas, have invented a new and useful Mine- Elevator, of which the following is a specification.

This invention relates to improvements in mine elevators or cages, the objects in view to being to provide an elevator adapted for raisvertical longitudinal section of a shaft, a cage constructed in accordance with my invention being mounted therein and located be1ow the point of dumping. Fig. 2 is a similar view, the cage being in the act of dumping. Fig. 3 is a detail of the cage. Fig. 4 is a transverse section thereof. Fig. 5 is a detail in perspective of one of the combined guides and yokes.

Like numerals of reference indicate like parts in all the figures of the drawings.

The shaft is provided with the usual framework, consisting, as herein shown, of the vertical uprights or posts 1, connected at intervals by transverse bars 2, betweenwhlch and the posts 1 oppositely-disposed inclined braces 3 are located. Opposite the top of the shaft side bars 4, wider than the bars 2, though corresponding therewith, are located, and from these side bars to the upper and lower ends of the frame-work vertical guide-sections 5 and 6 extend. The upper sections 5 and the lower sections 6 terminate short of each other at their adjacent ends, though, as shown, they are in vertical alignment, and each is but a continuation of the other. The adjacent ends of each vertical pair of sections 5 and 6 are beveled at opposite sides, so as to form an intervening space 7. From the lower sections 6 there extend upwardly and outwardly 1nolined track-sections 8, the inner ends of which are a slight distance from the upper ends of the sections 6. These track-sections have their'upper ends pivoted by bolts 9 to the side bars 4 and have their rear or lower ends removably secured by bolts 10, which pass through the track-sections and into the bars 4. If desired, these bolts 10 may be removed and the track-sections 8 swung to a vertical position or where they are inoperative, and locked in such position by entering the bolts 10 into suitable holes 11, formed in the bars 4 for this purpose.

In rear of the recesses 7 and having their' lower endspivoted by bolts 12 is a pair of declining tracks or sections 13, the same ex tending from a point in rear ofthe guides 5 up to within a short distance of the lower ends of the guides 4, but terminating short of the same, so as to leave an intervening space. The upper ends of the sections 13 are removably secured by bolts 14, passed through perforations in the sections and into openings formed in the bars 4. By removing the bolts and swinging the sections 13 rearwardly they may be locked in inoperative position by reinsertingthe bolts in suitable openings 15, located in rear of said sections and formed in thebars 4. r

In constructing the frame-Work of the cage I employ a strong rectangular base-frame 16, consisting of front and rear and opposite side bars, the ends of which are joined andsecurely bolted together. Metal straps 17 are bolted to I;

the upper and lower sides of this base-frame and arranged in pairs, and bolted between each pair of metal straps is an inclined hangerrod'18;

19 designates a superimposed suspensionbeam, and the same has embracing saddles or straps 20, located near its ends, to which are securely bolted the upper ends of the suspension-rods just mentioned. The cables for raising and lowering the cage orelevator are secured to this transverse superimposed suspension-beam. Guide-shoes 21 are secured to the opposite ends of the beam 19 and centers of the opposite side bars of the base-frame of the cage. These shoes are U-shaped in cross section and somewhat snugly embrace the guides 5 and 6, upon which they are adapted readily to move.

A pair of standards 21 rise from the front and rear ends of the base-frame, the latter standards being somewhat taller, preferably,

than the former, and each pair of standards constitute supports for transversely-opposite bearings 24. In these bearings 24rock-shafts 25 are journaled, and the same pass through eccentrics or eccentric-disks 25.

26 designates a car-supporting frame, from the opposite sides of which, near the front and rear ends thereof, depend hangers 27. These hangers are connected by bearing-pins 28 with eccentrically-formed holes 29, formed in the eccentrics before mentioned, so that, as will be obvious, the frame 26 is capable of pivotal movement upon the eccentrics. Located between the rear pair of standards is a stop-block or bolster, the same having rests 31 at its opposite ends, upon which the rear eccentrics normally rest. The rear eccentrics are connected at a relatively different point m ne hangers to what the front eccentrics are, so that as the front eccentrics move, so that their poi'n ts of connection with the hangers are the front of the same, the pivotsof the rear ececntrics will be at the upper sides and hence the frame 26 would be tippled or tilted, so'as to dump anythingtherefrom, In bearings 32, with which the opposite side bars of the frame 26 are proyided, a pair of shafts 33 are j,oi' 1 rnaled,'the ends of which ext d. yo'li h ll 26 and o rpos tesides o h verna ui a d, here h y re providedwith loose rollers 34:, adapted to rotat'efofver the 'oppositesides of the said vertical guides.

' shown in detail in Fig 5, the saddlesor. strapsand the guides at the opposite ends of the earn 19 may be formed integral.

Inoperation, if it is desired to raise coal from the pit, the sectiOnsS and 13of the track are. swun 9 t inclined ss ons; er to: fore described as their operative positions,) and can 35 is mounted pOn the frame 26 and locked against movement thereon. As theeler o scend h front a f o ler passes underj the tracksS, while therear pair connein contact with the rear tracks 13, are fleqted rdm th t econ s O r a d: pon h r ck's. pre u de mov n a hs upper i ertic'al guides 5 having passedthrough the: recesses intervenin g between the tracks 8,

and '13 and theguides 5 and 6. A continued movementu'pon the part of the cage causes the front eccentrics to. rotate, so as to lower the froln'tl end of the frame 15 and raise the rear en'd thereof, and. thus the coal is dis ohargcdffrem the car. i nto any waiting reeep l i W e e was, hsw el ningover the'tra'ek-sections 8 and 13 return thefcaifand, the frame 26to their proper posisens," Erem'this it will be seen that coal may beleaded into the carfsat the bottom of the pit orat any intermediate point andth'at the same maybe automatically delivered as soon as thecage reaches the upper end of the shaft. When it isdesired to throw the tilting m'ech'anism'out'of operatiomthe tracks 8 and 13 are swung to their inoperative positions and lochedby the means heretofore described,

shaft.

. claim is and it will thus be seen that the cage can pass up and down upon the guides 5 and 6 as if the latter were continuous, and is therefore safe for the transportation of the miners and others from the mouth of the shaft to the bottom of the shaft or any intermediate portion, or from thence back to the mouth of the Having described my invention, what I l.
