, ROTARY can rrrrnn.

Application filed June 15,

To all whom it may concern: I Be it known that I, ALEXANDER H; Noon, a citizen of the United States, residing at Kildav, in the county of Harlan and State of Kentucky, have invented new and useful Improvements in Rotary Car Tipples, of which the following is a specification.

This invention relates to improvements in rotary tipples or dumps for overturning mine and ore cars to discharge their contents, and more especially to improvements in the mechanism associated witha rotary tipple or car dump to hold the car or cars in the tipple during the overturning operay tion and to release the empty cars after they have been restored to their upright position. To this end there is provided within the rotating part of the tipple a pair of horns or stops to engage the cars, together with automatic mechanism operating in the movement of the tipple to withdraw and replace the horns or stops as is required for Figure 4 is a transverse vertical section on the line 4l-4e of Figure 3.

Figure 5 is a transverse vertical section on the line 55 of Figure 3.

As shown in said drawings the rotary tipple or car dump comprises acylindric frame or structure, 10, which is mounted to rotate upon an axis a little inclined to the horizontal, with rails, 11, inthe lower part of the frame to receive the cars, 12, through the higher end of the cylinder and discharge them through its lower end. For purposes f of better illustration the side walls of the cylinder, which prevent the contents of the cars from being spilled out sidewise, are here omitted as also the mechanism for rotating the cylinder and controlling its move ments, all of these parts being made in ac cordance with well-known principles and their particular design or construction not Specification of Letters Patent.

constituting any part of this invention. The cars enter the cylinder from a fixed length of track, 20, and being. unloaded through the dumping operation they leave over another section of track, 21 both of these fixed sections as well as the movable section 11 within the cylinder being inclined so that the cars will roll along by gravity.

In the lower part of the cylinder 10 between the two rails 11 and parallel thereto is a shaft, 25,.which is journaled in brack ets, 26, secured to the framing of the cylinder; this shaft extending outward a little beyond the lower end of the cylinder and carrying at its end a fixed crank arm, 27, which projects radially towards the axis of the large cylinder 10. At the required distance from the lower end of the cylinder to engage with the front wheels of a car which may enter the tipple, or if more thanone car is taken at a single operation, to engage with the front wheels of the leading car, as here shown, there are secured to the two rails 11.

a pair of horns or stops, 30; which latter project upward and are pivoted on horizontal pivots so that their upper ends may be spread apart to release the car. These horns or stops are made with integral crank arms, '31, which extend downward and are connected through drag links, 32, to fixed crank arms, 33, on the shaft 25; so that through the rotation of this shaft the two horns or stops 30 are spread apart to release the cars, or are brought back to their vertical positions,.according to the direction of rotation of the shaft; There is also fixed to the shaft 25 a crank arm, 4L0, to which is attached one end of a spring, 41, and the opposite end of thelatter is hooked into the end of a threaded eyebolt, 42, which engages in a bracket, d3, secured to the base flange of one of the rails. The spring acts normally to rotate the shaft 25 in such direction as to bring the horns 30 into their upright position where the movementof the parts is arrested by the engagement of the two horns against the heads of the rails as shown in Figure 4. By means of a nut, 45, on the end of the eyebolt 4L2 the tension of the spring may be adjusted, and the crank arm 40 is also made with a number of openings through it designed for engagement by a pin, 46, to secure the spring through a clip, 47, so that the radius of the arm may also be varied for the proper operation of the mechanism.

engaging against the horns.

Between the two rails 21 of the fixed section of track beyond the lower end of the cylinder 10, and in the vertical plane of the shaft when the cylinder is in its normal position, but a little above the shaft, there is arranged a second shaft, 50, which is mounted to slide endwise in brackets, 51. A coiled spring, 53, engaging age 1st one of these brackets and against a time collar, 54;, on the shaft acts normally to slide the shaft end- Wise in a direction toward the cylinder 10; and at the opposite end of the shaft there is pivoted to the track bed an upright extending trigger, 60, which is connected through a pair of links, 61, to the end of the shaft; this trigger being adapted for striking by a car axle passing over it to withdraw the shaft against the pressure of the spring 58. T he length of the shaft 50 is such that the trigger will be spaced from the end of the cylinder 10 the distance of the first axle of a car or cars leaving the tipple when the last axle is just clear of the horns 80, and the end of the shaft 50 which is adjacent to the cylinder 10 is adapted to extend into the plane of movement of the crank arm 27.

The operation of the mechanism is as fol lows:

Assuming that the two horns are in their upright or closed position through the action of the spring 41 upon the shaft 25, a car or cars are allowed to enter the tipple along the track 20 whereupon their movement is arrested by the front pair of wheels The tipple is then operated to overturn the cars, and upon its return movement, which is indicated by the curved arrow in Figure 4-. the projecting crank arm 27 on the shaft will strike against the end of the shaft 50 and throw the horns open. The car or cars will then roll out of the tipple and as soon as the last axle has passed the horns 30 the leading axle will strike against the trigger 60 and side the shaft 50 endwise so that the crank arm 27 can snap back into its vertical position through the action of the spring 41, thus closing the horns again and leaving the mechanism ready for the entry of another car or cars into the tipple. As the successive car axles pass over the trigger G0 the latter will be pulled down to permit them to pass, and on each return movement of the trigger to its iupright position, under the action of the spring 53, the end of the shaft 50 will be arrested against the side face of the crank arm 27 to prevent any interference With the overturning niovemoiit of the tip ple. But as soon as the crank arm 27 and the shaft 50 are disengaged by the operation of the tipple the end of the shaft will slide out into position for engagement by the crank arm 2? on the return movement of the tipple, as above described.

I claim as my invention:

l. In a car unloading apparatus, the comblnation of a rotatable dump structure having rails therein to rece' e a car, a fixed ap proach track leading thereto, a fixed recciv- 111g track leading therefrom, a movable stop within the rotatable structure to hold a car: said stop adapted to be relea ed t "iove1nent of the structure fron s overturning position to its normal u it position, a part on the fixed recei Jack, and means for resetting the aid means lng set in operation by contact of a passin car with the part on the tired track.

2. In a car unloading apparatus. the no bination of a rotatable dump stru? ing rails therein to receive a car, a approach track leading thereto, a iii- Gil reeeiving track leading therefrom, a movable stow within the rotatable structure, means for yieldingly holding said stop in its set position, said stop adapted to he "elcased through movement of the structure from its overturning position to its normal upright position, and a part on the fixed receiving track acting through engagement by a passing car for permitting the stop to be reset, said part on the fixed receiving track being operatively connected to the resetting mechanism.

3. in a car unloading a aratus, the combination. of a rotatable car dump structure having an inclined track, fixed inclined approach and receiving tracks connected therewith, amovable stop within the dump structure to hold a car, said stop adapted to be released through movement of the structure from an overturning position to its normal upright position, a part on the fixed receiving track, and means ior resetting the stop, said means being set in operation by contact of a passing car with the part on the fixed receiving track.

In witness whereof, I have hereunto subscribed my name this 11th day of June, 1917.

ALEXANDER H. WOOD.
