WILLIAM rn'rrrsoiv;

To allwhom itvmay concern: 7

Be it known that I, WILLIAM PATTISON, a subject of theKing of Great Britain and Ireland, and resident of Widnes, Lancashire, England, have inventedcertain-new and useful Improvements inorBelating to Tipping Mechanism for Railway and like Wagons, of which the following is a specification. 10 This invention relates to tipping mechanism for railway and the like wagons of the kind in which the wagon is tipped bodily, to discharge the contents. The ob- .ject of the invention is-to, rovide improved efiecting the tipping of the wagons. 4

According to the invention, the improved apparatus comprises a platform on to which the wagon can-bemoved-and at the ends of which are-pedestals, one orboth of which means adapted to be advanced towardthe wagon end, and; form centers about which said, Wagoner wagon and platform can revolve. The jacks areoperated by. suitable means, such as by screws, or: hydraulically, 80-and the. rotary movement of the wagon is adapted to'actuate the jacking mechanism which in addition to raising thefiwagon bodily, acts as abrake' in order to bringjthe wagon to rest at, the correct position, said wagon afterward being lowered .to the correct'level. f 'A practical embodiment of the invention will now be describedwith reference to the oaccompanying drawings, in whichz Figure 1 is afsideyelevation of .a portable form of the invention ,j-with a wagon 1n posi- Fig. 2 iswa planflview with the wagon removed.

along a railwaytrack c. The carriage has nclined rails 01 leadingto. a platform 6 upon which are secured rails f forming a. contlnuationof, or connecting, the two sets of incllned rails at either end of the carriage van. The platform is supportedu'pon four uprights g each-pivotally connected at h to the carriage a. Horizontal extensionsfg' of the/uprights g are connected in pairs von each side of the carriage by'links 2'. At the center of each link is a pin. j vone of which 5 enters aslot formed at oneendof' a lever 70, while the other enters a slot formed in the other end of said lever which is pivoted at .70 the center 7a, to the carriage a. .A handle 16 is securedto the lever is, or to theaxle of. the same, byvmeans of which said-lever is moved around its pivot, which movement is 1 transmitted to the uprights g to swing the same clear of the platformrqas shown in dotted lines in Fig. 2. V 5

Means are provided ateitherend of the carriage, atoigrip and center theiwagon and as said means are identical: at both ends, the mechanism at one end only will be described. 7 Cross-wise of thecarriage a v is a shaft l 1 Hjournaled in brackets, fixed to the framing atreither side. The ram m' ofan hydraulic vjackis secured to the shaft Z andtrotates therewith. Saidram is located in the pres sure cylinderabove which is fixedthe water reservoir 7 containing the plunger 'pump; 0 .worked by the handle 1) in the well known mannen. The top of the reservoir is p'rovided; with an 7 extension having a. transverse screwed Thole therethrough to .receiveja c ewe pi d qiwhiehis t by an of the handle a At the opposite end of the spindle g arfitting rs isrrotatably mounted jwhich isadapted to engageand gripthe .end of the wagon, a thrust bearing being provided to; insurexthat the turning move- Inent of the fitting-e, fin operation;,is not tran mi ted ol h r leia Upon the tfi t't ing s and eccentrically to the-spindle, is f0rmedan eccentric s to receive an eccentric strap s nthe ,rod s of which connects with, and operates,{the plunger tof a power pump j; u. -,.The suction valve o'f; the-E pump. commiunicates-withthe reservoirm, while; the

plained. To effect this axial movement the shaft Z is formed with a rack Z with which meshes a pinion m on the ram on said pinion being turned by means of the hand-wheel m Upon the shaft Z is also'rigidly secured the pinion c which meshes with a small pinion i0 fixed to the shaft 00. The latter is also mounted in brackets, cross-Wise of the shaft, and is provided with a handle located exteriorly of the carriage framing, by means of which the shafts w and Z may be rotated in order to raise, or lower, the jack. A strut or the like, may be provided to retain the jack in the raised position, or, as shown in the drawings, a cross bar 3 maybe passed through holes in the framing formed to re,- ceiveit, just rearwardly ofthe jack and in contact with the same.

A second jack, similar in all respects to the first is mounted at the opposite end of the carriage and the operation of the device is as follows: The carriage or is moved along the track 0, to the place where it is desired to tip the wagons and is then secured in position by wedging or scotching. Assume ing the platform 6 to be in position resting upon the supports 9, with the jack at the right hand side raised, and the jack at the left hand side lowered, as shown in dotted lines in Fig. 1.

The wagon is forced up the incline on to the platform and the jack is then raised by turning the handle ofthe shaft. It is then secured in position by the cross-bar 3 after which therjack is adjusted transversely by means of the handwheels m until the spindle g lies slightly to one-side of a line passing through the center of. gravity, of the wa on and load in. order to insure a preponderance of weight upon' that side on which it is desired to tip the wagon. .The

fitting sis then advanced by rotating the i spindle 9, until the wagon is firmly gripped and connect and held as shown in Fig. 1. Chains 2 are then passed over Qthebufiers of "the wagon the same securely to the. platform. Q i 1 When the platform and wagon are .connected together, the supports 9 arev moved suspended upon the spindles 'g which constitute centers forum same. Immediately the supports 9 are removed the loaded wagon tips in the required direction due to plained. The preponderance of weight on the lower side increases duetothe act of I 1 .At this position the wagon is empty, but the wheels and platform, which are now com- *paranvsr heavier, are: in the act of'descend= ing on the opposite side of the center of rotation. At this point the eccentric s which has been raising the plunger t during the upward movement of the wagon, begins to force the said plunger downward, thereby forcingwater into the pressure chamber.

readily moved under said platform. A return valve 2 is provided to allow the water to flow back into the reservoir in order to lower the jack and permit the platform to descend on to the supports. One or both of the 'jacks is, or are, then lowered to permit the removal of the wagon and toallow another one being placed in position.

Instead of the portable carriage a the device may be constructed as a permanent- -structure and it may also be arranged on the ground level for use with a conveyer belt or'the like. In. this case the jacks and other working partswould be arranged to descend below the level of the axle of the, wagon P I while placing the same in What I claim is I 1.
