AUTOMATIC CAR-TIPPLE FOR MINES.

SPECIFICATION forming part of Letters Patent No. 645,155, dated March 13, 1900.

Application filed May 8, 1899. Serial No. 716,051. (No model.)

To all whom it may concern:

Be it known that I, CHARLES I-LWILLIAMS, of the city of Ooffeen, county of Montgomery, State of Illinois, have invented certain new and useful Improvements in Automatic Car- Tipples for Mines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to tilting cars and platforms for mines; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

Figure 1 is a longitudinal sectional view taken through the center of one of my improved cars and platforms. Fig. 2 is a vertical sectional view taken approximately on Fig. 3 is a view analogous to Fig. 1 and showing the car and platform in a tilted position. Fig. 4 is a view in perspective of the lower end of a hook that engages the cage or door at the discharge end of the car. Fig. 5 is an enlarged vertical sectional View taken approximately on the line 5 5 of Fig. 1.-

Referring by numerals to the accompanying drawings, 1 indicates the. body of my improved car, the same being rectangular in plan View and mounted upon suitable small flanged wheels 2. One end of the body 1 is open, the same being normally closed by a gate or door 3, the same being provided with a hook4 on its top edge. This door or gate 3 is provided with rearwardly-extending arms 5, the same being pivoted to the upper portions of the sides of the car-body 1.

6 6 indicate corner-posts of the framework which surround the hoisting-cage or elevator, the same extending down into the shaft of the mine in the usual manner, and at each side of this framework is arranged a tilting platform 7, the same being in horizontal alinement with the floor of the mine. Thisplatform 7 is hinged upon the transverse rod 8, the same being supported at its ends in any suitable manner, and on top of said tilting platform 7 is arranged a pair of rails 9, the

. same being in direct alinement with the rails 10 of the car-track leading to the tilting platform, over which car-track the car passes to the point where it is filled.

Upon the rails 9 of the tilting platform 7 are bolted blocks 11, against which the front wheels of the car engage when said car is run onto the tilting platform. These blocks 11 have U-shaped grooves 12 formed in their under sides, which pass directly over the tops of the rails 9.

Fixed to the under side of the forward end of the platform 7 is a downwardly-pending bracket 13, the lower end of which extends laterally into the space traversed by the cage or hoisting-car, and upon the end of said bracket 13 is hinged an arm 14, the same being arranged to swing upwardly and which arm 14 projects outwardly into the path of travel of the hoisting-cage.

Hinged between a pair of eyebolts 15, that are secured to a cross-beam 16 of the frame in which the hoisting-cage operates, is the upper end of a rod 17, the lower end of which is provided with a hook 18, which hook. normally engages against the door or gate 3 at a point just below the hook4 when the car 1 is run onto the tilting platform. 7.

Fixed upon the top of the rear end of the tilting platform 7 is a loop 19, and operating in the loop 20, fixed upon the floor of the mine adjacent this loop 19, is a bar 21, said bar being for the purpose of engaging in the loop 19 when it is desired to lock the tilting platform 7 against movement.

The operation is as follows: The platform 7 being hinged or fulcrumed slightly in front of the center normally occupies a horizontal position, with its rear end resting upon the support positioned immediately beneath said rear end, and after the car 1 has been filled it is run onto the tilting platform 7 in any suitable manner until the forward wheels of said car engage against the blocks 11. When in this position, the hook 18 of the rod 17 is in a position outside of the door or gate 3, immediately below the hook 4 thereof. The hoisting cage now descends through the framework composed of the timbers 6, and just before said cage reaches the lowermost limit of movement it will engage againstthe projecting arm 14, and as the same is carried downwardly with the cage the platform 7 and the car 1, carried thereby, will tilt forwardly into the position shown in Fig. 3, and simultaneous with this movement the hook 4, carried by the gate or door 3,will engage in the hook 18 of the rod 17, and said gate or door will be pulled upwardly, as shown in Fig. 3, to allow the contents of the car to discharge into the hoistin -cage, which when the platform and car are tilted occupies a position at the lower end of the framework composed of the timbers 6, as shown by dotted lines in Fig. 3. When the hoisting-cage is elevated, the platform and car will reassume their normal positions and the gate or door 3 will automatically close upon the end of the car-body.

Should it be desired at any time to run the car onto the hoisting-cage, the blocks 11 are removed from the rails 9, after which the bar 21 is moved forwardly, so that its end engages in the loop 19, thus preventing the platform from being tilted, and finally the arm 14 is swung upwardly over onto the bracket 13 out of the way of the descending hoisting-cage. The track is now clear onto said hoisting cage, and the tilting platform 7 is held against movement in any direction. Consequently a loaded car can be run directly onto the hoisting-cage, and when this is done it will of course be necessary to swing the rod 1'? upwardly as the car is run onto said cage.

A tilting car and platform of my improved construction is applicable for all mines, is automatic in operation, and very quickly and efficiently discharges its load into the hoisting cage.

I claim- 1. In a device of the class described, a framework with a descending cage, aplatform arranged to be tilted into the side of the framework in which the cage operates, in combina tion with a car adapted to occupy said plat form, said car having a door normally closing one end thereof and hinged thereto, a hook whereby said door is engaged and opened when the car and platform are tilted, an arm carried by the under side of said platform to be engaged by the descending cage for tilting said platform, substantially as specified.

2. In a device of the class described, having a descending cage operating in the framework, a tilting platform arranged at one side of said framework, rails provided with stops mounted upon said platform, a car occupying the rails of said platform and provided with a door hingedly secured to said car and provided with a hook, said hook constructed to engage a hook swinging from the framework and when engaged to open said door when the car is tilted, an arm secured to the under side of said platform and engaged by the descendingcage for tilting said platform, substautially as specified.

3. In a device of the class described, the combination of a hoisting-cage operating in a framework, a tilting platform arranged at one side of said framework and provided with rails for the admission of a car, a door forming one-end of said car, said door hinged to the sides of said car and provided with a hook,

said hook arranged to come in communication O. H. WILLIAMS.
