CHARLES S. FARRER, OF DUNMORE, PENNSYLVANIA.

TIPPLE.

SPECIFICATION forming part of Letters Patent No. 617,087, dated January 3, 1895. Application filed .Api-i1 25, 1898. Serial No. 678,755. (No model.)

T0 a/ZZ whom it may concern:

Be it known that I, CHARLES S. FARRER, of Dunmore, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Tipples, of which the following is a full, clear, and exact description.

This invention relates to dumping apparatus or tipples, but more particularly to such devices as are employed for conveying and dumping material from mines into railwaycars and the like for transportation purposes.

The primary object of the invention is to provide a tipple which will be under the complete control of the operator and which will readily hold the car on the tilting platform or rail-section, so that the material may be deposited from the car and the car automatically returned to its normal position.

A further object of the invention is to provide simple and efficient mechanism for holding the car on the tilting platform, so as to be properly emptied of its contents, and to provide automatically-actuated means by which the tilting platform may be held in its normal position or which will permit the platform to be tilted or rocked to an inclined position.

With these and other objects in view the invention consists in the construction and combination of the several parts, substantially as hereinafter described, and then pointed out in the claims at the end of the description.

Referring to the accompanying drawings,

forming a part of this specification, Figure I is a longitudinal section taken on the line- I I of Fig. 2, showing in full lines a side elevation of the car and tilting-platform, their normal position, and in dotted lines the car and platform in a tilted or inclined position. Fig. 2 is a plan view of the tipple, a portion of the operating mechanism being broken away and brought together to more clearly illustrate the working of the same. Fig. 3 is a fragmentary rear end view of the tilting platform and mechanism with thecar in the position shown in Fig. I. Fig. 4 is a vertical sectional view taken on the line IV IV of Fig. 3, illustrating one position of the operating mechanism. Fig. 5 is a similar view to Fig. 4, except that the mechanism is shown in another position; and Fig. Gis a sectional View of the latch or locking device for the tilting platform.

The tilting platform or rail-section I0 has the side or rail beams Il connected together by suitable stay-rods, so as to be rigidly held apart, and has a plate l2 secured between said beams. Projecting outwardly from the beams 1l are racks 13, having teeth on their under surface, engaging the teeth of the curved or scroll racks I4, these latter racks being suitably supported by the usual or any preferred form of stationary framework. The rail or side beamsV Il form a continuation of the usual track and are adapted to support the cars l5, as shown in Figs. I and 3.

For the purpose of properly holding the car upon the tilting platform or rail-section IO prior to and while in a tilted position I arrange suitable stops, as I6, so as to move with the platform. As shown, these stops are secured to a shaft 17, journaled in the platform IO and arranged adjacent to the beams Il. These stops have hooks or curved projecting portions I8, adapted to engage the flanges of the wheels 18"L of the car, and counterbalances or weights 19,' projecting outwardly from the shaft in an opposite direction to the hooks IS. The stops have a lower straight or plane surface 20, which when in the position shown in Figs. l, 3, and 4 is adapted to be engaged by the cams or knees 2l, the latter being secured tothe transverse shaft 22, journaled in pendent portions or bearings 22a of the platform IO. The knees or cams 2l are adapted to be rocked or oscillated with the shaft 22, and when in the position shown in Figs. I and l the straight or plane surfaces 23 will rest against the lower surfaces 20 of the stops 16, so as to rigidly holdthe same in an upright position, a plate 2.3a being secured to each pendent portion 22, which limits the downward movement of the knees when the latter are operated to permit the stops I6 to lower. This transverse shaft 22 has a pulley or sprocket-wheel 24., around which may be arranged a chain 25, which passes over a similar pulley or sprocketwheel 2G, secured to a suitably-supported shaft 27, said latter shaft being held in suitable stationary bearings or in bearings which will yield slightly to the movement of the tilting platform. The shaft 27 has a pulley or sprocket-wheel 28 thereon, around which passes a chain 29, secured at one end to said, pulley or sprocket-wheel and at its other end to an oscillatory lever 30, so that when the lever is operated the shaft 22 will be rocked in its bearings by means of the chain 25, which passes around the pulleys or sprocketwheels 24 and 26. The operating-lever 30 is arranged on a bolt or shaft 31, which is secured in a suitable bracket 32, and on the bolt 31 is another lever 33, similar to the lever 30, which is connected by a chain 34 to a pulley 35, this latter pulley being secured to the shaft 27 and having the chain thereon arranged to rotate the same and the shaft in an opposite direction to that secured by the chain 29 and pulley 28.

The shaft 22 intermediate the stops 16 is provided with an arm or crank 36, to which is pivoted a rod 37, this rod being passed through and suitably supported in a bracket 38, arranged upon the platform 10, the plate 12 of the platform being cut away, so as to permit the arm 36, as well as the stops 16, to move above the same. On the rod 37 and on opposite sides of the bracket 38, which is secured to the plate 12 of the platform, are the springs 39 and 40, which are opposed to each other and held adjustably upon the rod 37 by means of the lock-nuts 41, the function of the spring 39 being to start the stops 16, so that they will be thrown suddenly downward, while the spring 40 is adapted to assist in arresting the downward movement of the stops and the connecting mechanism.

To release the tilting platform or to hold the platform in a horizontal position, a rod, as 42, is connected at one end to the stops 16 and at its other end to a slide or plunger 43, which is held in brackets 43, secured to the beams 11 of the tilting platform. The pl-ungers or slides 43 when the stops are in a raised position are adapted to engage the ends of locking devices or latches 45, which are slidingly held in suitable casings 46,- secured to a support 47, on which support may be also arranged a portion of the track, as 47a. Each latch 45 is normally pressed outward by a spring 48, Fig. 6, arranged in the casing, and is prevented from being thrown too far by a bolt 49, which passes through the casing and a slot 50 in said slide, so that when the stops are in the position shown in Fig. 5 the spring 4S will force the latch or locking device outward beneath the end of the adjacent beam 1l, so as to hold the platform in a horizontal position; but when the stops are raised, as in Fig. 4, each plunger through the reach or connecting-rod 42 will engage the end of the latch or lookin g device 45 adjacent thereto and force the same away from the end of the platform, so that the latter may lower by the weight of the car.

The operation of the invention will be readily understood from the foregoing deeimerv scription when taken in connection with the accompanying drawings.

The cars are run onto the heel of the tilting platform or rail-section 10 in the direction indicated by the arrow in Fig. 1. Then the first two wheels of the car run on the end of the platform, the operator pulls back the lever 30, which operates the pulley or sprocketwheel 28, and through the shaft 27, pulleys 26 and 24, shaft 22, and cams or knees 21 will throw the stops 16 to the position shown in Figs. 1 and 4 to receive the flanges of the forward wheels of the car. Just prior to the engagement of the forward wheels of the car with the stops 16 the plungers or slides 43 through the rods 42 will disen gage the latches or locking devices 45 from the ends of the platform 10. The weight of the car will now tilt, or rock the platform 10 on the scroll or curved racks 14 to an inclined position, so that the material may be properly deposited into a receptacle provided therefor, as shown in dotted lines in Fig. 1. During the movement of the cars and tilting platform the fulcrum or weight is shifted, so that as the material passes out of the car the weight of the car and the rear end of the platform will be sufficient to automatically restore the platform with the car thereon to its normal or horizontal position. After the car has been emptied of its contents the lever 33 is operated, and through the chain 34, pulley or sprocket-wheel 35, shaft 27, pulleys 26 and 24, and shaft 22 the knees or cams 21 will be thrown downward, so as to rest against the stop-plates 23, as shown in Fig. 5. As soon as the lknees are released the spring 39 through the rod 37, arm 36, and shaft 22 will start the stops 16, so that by the weight thereof and the connecting mechanism the hooks 1S -of thestops will be thrown suddenly downward to the position shown in said ligure. This movement of the stops through the rods 42 will withdraw the slides or plungers 43, so that the latches or locking devices 45 will engage the lower surface of the platform, so as to rigidly hold the same in a horizontal position. The car may now be run off the tilting platform ready for the next full car. Grdinarily in operating the levers after the stops have been thrown to an elevated position the lever 30 is again thrown forward, and in like manner the lever 33 after being operated for throwing the knees or cams 2l downward is also thrown forward and left in this position, allowing-the slack in the chains to be taken up by the movement of the plat` form.

I thus provide simple and efficient means whereby the movement of the car and tilting platform or rail-section is under complete control of the operator, so that the car may be readily emptied and automatically returned to a horizontal or raised position.

While I have described a particular form of tilting platform, it is to be understood that IOO IIO

this may be of any desired construction and arranged in any suitable manner and that the means for operating the stops, as well as some of the other parts, may be varied without departing from the spirit of my invention.
