MINE APPARATUS.

Application filed May 14, 1918.

To all whom it may concern:

Be it known that I, ALnnn'r BUCEY, a citizen of the United States, residing at Bowerstown, in the county of Harrison and State of Ohio, have invented new and useful Improvements in Mine Apparatus, of which the following is a specification.

This invention relates to an apparatus for handling cars in a mine and more particularly to an apparatus for feeding cars onto and off of the cage and has for its primary object to simplify and thereby reduce the expense of an apparatus of this character.

An object of the invention is to provide an apparatus in which only three stops can accomplish the work of the usual four stops necessary in the apparatuses now in use.

Another object of the invention is to provide mechanism that may, without changes, be attached to the top surface of a cage or the under surface depending upon which is the most advantageous in practice when used on the different type cages now in use.

Besides the above my invention is distinguished in the use of cage mechanism and trackway mechanism of substantially the same construction for feeding cars onto the cage and off the cage.

With these and other objects in view the invention will be better understood from the following detailed description taken in connection with the accompanying drawings wherein:

Figure 1 is a top plan view of a cage showing my invention applied thereto.

Fig. 2 is a longitudinal sectional view.

Fig. 3 is a detail view of a portion of the link mechanism. Fig. 4 is a sectional view through a rail showing the rear stop in elevation. Fig. 5 is a detailed view of the car actuated lever. Fig. 6 is a top plan view of the trackway mechanism. Fig. 7 is a detailed view of one element of the clutch. Fig. 8 is a detailed view of one of the stops.

Again referring to the drawings the numeral l designates a shaft consisting of two parts 2 and 3, both mounted for rotatable movement in bearings A while part 3 is also mounted for longitudinal sliding movements. One end of the shaft in this particular instance the part 2, has connected thereto a crank arm 5 adapted to strike a stationary arm 6 Within the mine when the cage 7 reaches predetermined positions.

A clutch device 8 is arranged to normally connect the parts 2 and 3 together and in Specification of Letters Patent.

Serial No. 234,462.

each of the parts 2 and 8 is a coil expansion spring 12 having one end fixed to a collar 13 on the part and the other end fixed to one of the bearings 1. By this arrangement it will be seen that one of the coil expansion springs 12 performs a dual function of forcing one part toward the other part and besides both springs return the parts to normal position, when partly rotated by the crank arm 5 striking the arm 6. The expansible action of the spring 12 normally holds the clutch elements in engagement with each other so that the parts will move as a unit when pressure is applied upon the crank arm 5. At certain times it is necessary that the clutch be rendered inoperative for accomplishing an operation hereinafter described. For this purpose I provide a car actuated lever 13 pivoted to a bracket 15 and further pivotally connected to one end of a link 16 the other end of which is forked as indicated at 17 and arranged behind the collar 13*. For the purpose of absorbing shock a spring 18 is arranged between the fork 17 and the adjacent bearing 1. As far as I have proceeded it will be seen that when the crank arm 5 strikes the arm 6 both parts of the shaft will be rotated as a unit; whereas upon a car axle striking the lever 14.: the part 8 will he slid longitudinally for disengaging the clutch elements, thereby allowing the part 3 to rotate independently of the part 2 by the torsional action of the spring 12. Projecting from the element 8 are arms 19. Pivotally connected to the rails are stops 20 and 21.

The stop 20 is connected to the arm 19 by a link 22 and yieldably forced in a predetermined direction by a sprin 23. The stop 21 is connected to a second pivoted lever 24: by a link 25. The lever 24 is also pivotally con: nected by a link 26 to the arm 19. To complete the cage mechanism I provide a third pivoted stop 27 normally forced to an operative position by a leaf spring 28. This stop 27 is provided with a cam surface 29 so as to be automatically forced to an inoperative position in the passage of a car.

The track-way mechanism 30 is identical to that described with the following exceptions;

The crank arm 31 is constructed to be engaged by a descending cage. One part of the shaft has connected thereto a weight 32 normally holding the parts in predetermined positions. As an improvement over the cage mechanism the spring 33 of the trackway mechanism consists of two parts 3% and 35 each acting against a bearing 86 and a collar 37 fixed to the shaft. Working between the collars 37 is the forked end 38 of a link 35. The remaining parts of the trackway mechanism are identical to the cage mechanism with the exception that the element 40 of the clutch device is provided with diametrically arranged ears ll pivoted to links that are directly connected to the stops as.

From the foregoing description taken in connection with the drawings it should be apparent that I provide a simple mechanism of substantial construction in which the parts are so arranged and constructed that the operation of the apparatus is assured,

with a minimum number of parts.

It is of course to be understood that the mechanism may be constructed in various other ways than that shown, which is illustrated in the simplest form, all mechanical details being eliminated. Therefore I do not desire to be limited to the exact showing exact showing except as set forth in the claim appended.

Having described my invention, what I claim is:

A mine car handling apparatus comprisinga two part shaft, a crank rigidly connected to one end of the shaft, a clutch device consisting of two elements rigidly connected respectively to said parts, said parts being slidably related, car stopping and releasing means having a connection with one of the elements, a. collar fixed upon one of said parts, a pair of coil springs mounted on said shaft and abutting a stationary support, one of said springs being capable of returning said shaft part which it is associated with to normal position, and a car operated pivoted lever engaging said collar between said springs for the purpose set forth.

In testimony whereof I afliX my signature.
