CAR-DUMP.

SPECIFICATION forming part of Letters Patent No. 779,391, dated January 3, 1905.

. Application filed June 20, 1903. Serial No. 162,345.

To all whom, it may concern:

Be it known that I, EUGENE BIVERT, a citizen of the Republic of France, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Dumps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and

t the letters of reference marked thereon, which form a part of this specification.

This invention relates more particularly to a device adapted to receive a loaded car or other vehicle therein and to unload the same by inverting or partly inverting the car.

Heretofore various types of car-unloading devices have been constructed, some of which operated by partly inverting the car. In most cases, however, the device was slow in operation, and the devices for securing the car in the cage or dumping apparatus fre quently are slow in operation and insecure at the best, thus not only wasting considerable time in securing the car for unloading, but also rendering the operation more or less dangerous.

The object of this invention is to provide a construction in which the car can be quickly looked upon its track from movement and so constructed as to enable the car and its contents to be inverted with safety.

It is also an object of the invention to support the car on an axis in alinement with the center of gravity of the car and cage, thus obviating to a great extent the tendency of the car to a violent lateral movement, thus relievingthe mechanism in great part, which would be due to an unbalanced condition common in constructions of the sort.

The invention consists in thematters hereinafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure 1 is a top plan view of a device embodying my invention. Fig. 2 is a side elevation thereof somewhat broken. Fig. 3 is an end elevation of the same, showing the cars secured in the cradle. Fig. 4 is a similar view, but showing the locking devices released from the car. Fig. 5 is a section taken on line 5 5 of Fig. 2. Fig. 6 is an enlarged detail plan view with parts omitted, illustrating the hoists and operating mechanisms at one end of the construction. Fig. 7 is a fragmentary side elevation of the hoisting and operating mechanism inserted in Fig. 6. Fig. 8 is a section taken on line 8 8 of Fig. 6. Fig. 9 is an enlarged detail of the winch and connections for dumping the car. Fig. 10 is a section taken on line 10 10 of Fig. 9. Fig. 11 is an enlarged end elevation,partly in section, of one end of the cradle. Fig. 12 is a top plan view of the same. Fig. 13 is a bottom plan view thereof. Fig. 14 is a side elevation of the same. Fig. 15 is an enlarged detail, in side elevation, of the pivot-shaft and connections upon which the car and cradle turn. Fig. 16 is a section taken on line 16 16 of Fig. 15. Fig. 17 is a section taken on line 17 17 of Fig. 15. Fig. 18 is a top plan view of the same, showing same free from all the cable attachments or blocks excepting one. Fig. 19 is a top plan view of one of the cable-attaching blocks.

As shown in said drawings, a frame is constructed of structural iron or other suitable material comprising the uprights A, A, A", and A arranged opposite corresponding uprights A*. Said uprights or posts are connected longitudinally at the top by means of a plate a and transversely of the top by the beams 60' a a a and at a point below the track-level are connected by transverse sills (t a a a as shown, supported on the beams A and A, which extend longitudinally of the frame and are connected at their ends onthe posts A A A A and the corresponding posts on the opposite side of the frame.

Supported on the sills a a a a and slidable longitudinally thereof are the upwardlydirected inner and outer pairs of supports B B, respectively, which, as shown, are shaped to receive and support the transverse segmentshaped members of a cradle upon which the car is supported during the dumping operation. Means are provided for sliding said knees B and B oppositely from or toward the center of the frame, comprising, as shown, a l screw-shaft .7), provided at opposite ends from the center with right and left threads and journaled at its ends, respectively, on the sill and the adjacent post. On the outer end of each screw-shaft is a bevel-gear Z2, meshing with a complemental bevel-gear 5 secured on.

a shaft 6 which extends longitudinally of the frame and is provided at its ends with handwheels 6 to permit of manual operation. The rotation of said shaft acts to drive all of said screw-shafts, shifting the knees or supports inwardly into supporting position for the cage or outwardly, as shown in Fig. 5, in position to permit the cage, with the car thereon, to swing clear. Said cage, as shown, comprises transverse segment-shaped supports C, as shown, constructed of structural iron and adapted to rest on said knees and rigidly connected by means of longitudinal I-beams C, having thereon track-rails continuous with the tracks of the end of the frame. Connecting the adjacent pairs of cradle-segments on each side of the center and at each end of the cradle are the shafts G Said shafts, which are rigidly secured at their ends in said transverse cradle-segments, act as rigid braces for each end of the cradle at the points on which the car-trucks are supported and also afford means for securing the car on said cradle, as shown in Figs. 2, 3, and 5. Secured on each of said shafts (J are the collars (Z, having each an eye thereon in which a chain (Z engages. Said chain is provided at its free end with a hook which engages in the eye (Z of a turnbuckle D, one of which is rigidly but adjustably secured at its upper end to each end of atransverse clamping-beam D, adapted to engage across the top of the car and which is adjusted by means of said turnbuckles to rigidly clamp the same to the track. Pivotal] y secured near the outer ends of said shafts C are the outer and inner supporting-bars E and E, each provided with a turnbuckle therein and having at the upper end a transverselyapertured head 0, adapted to receive therethrough the shaft Said supporting-bars E and E are of a length sufficient to extend upwardly and inwardly from said shafts G converging at a point approximately coincident with an axis drawn through the center of gravity of the loaded car and the cradle, as shown 'in Fig. 3. The pivotshaft E is provided with a feather e on each side thereof, as shown in Figs. 15 to 18, and slidably secured thereon are the blocks 0 which are provided on each side with a seat to receive said feathers a and through which said shaft passes. As shown, said block 6 and the head of the turnbuckle-bars E and E are arranged alternately on the shaft E and cables ff are rigidly engaged at their ends at opposite ends of said blocks and extend upwardly thereof over winches F, located at the top and each end of the frame. Said winches F, as shown, comprise the parallel longitudinal shafts F F, journaled on each side of the frame at each end thereof on trans verse beams G and G, which are supported transversely on the plate a. Each of said shafts is provided with grooved pulleys f for the cables ff. Means are provided for revolving said shafts, with the pulleys thereon, oppositely, comprising brackets F, supported on the beam G and through which the shafts F pass. J ournaled transversely at each end of the frame and at the top of said brackets is a rotative shaft H, having secured thereon at the head of the brackets the right and the left worms IL 72,, respectively. Said worms each engage a complemental gear-wheel H, carried on the shaft F directly below the same and which acts to-communicate the rotation of said worms to said pulleys. Means are provided for actuating the shaft H, comprising a gear 7L3, rigidly secured on one end thereof, and a pinion 7f, journaled on the frame in mesh with said gear, is provided with a crank if, whereby said gear is actuated. Means are also provided for lifting the transverse clamping-beam D, comprising a shaft H journaled on brackets 7L, supported on the plate a, and provided with grooved pulleys 71, secured thereon, to which are attached the lines 708, provided with hooks at their extremities adapted to engage in eyes at the top of said clamping-beam D, as shown in Fig. 8. A gear-Wheel h is secured on one end of said shaft H and a pinion h is journaled on the frame and meshes therewith and is provided with a crank 7a for actuating the same in a familiar manner, thereby enabling said clamping-beam to be manually raised or lowered. For the purpose of enabling an operator at the crank h to aid in the operation of hoisting the car and cradle a bevelgear I is secured on said shaft H intermediate the middle and near each end thereof, which meshes, respectively,xvith a complemental pinion 2', rotatively secured on each of the shafts F, near the end thereof. The hub of said bevel-gear i is shaped on its inner side to afford engagement with a clutch I, feathered on each shaft F and slidable into or out of engagement with the hub of said bevel-pinions '5 by means of the arms i secured on a transverse shaft I one of which engages each clutch. A lever i is provided at the end of said shaft 1 in position to be conveniently engaged by an operator at either crank.

Supported on the posts or uprights at one side of the frame is the laterally-projecting platform K, extending the entire length of the frame and at a height to enable the operator to conveniently operate the winches F at the top and ends of the frame, secured on said uprights or posts. Horizontal shafts 7c 71; are journaled on said uprights and provided at their ends in alinement with the transverse segments 0 G with grooved cable-pulleys /11 The shaft 7s and pulleys 70 are located near the top of the frame and on the outer sides of the posts, while the shaft 7c and pulleys are located below the cradle and on the inner side of the posts and cables it are trained around said pulleys. One end of each cable passes upwardly and inwardly from the pulleys 70 and is rigidly attached near the upper corner of the transverse segment member and the other end passes over the pulleys and extends downwardly and inwardly and beneath said segment, which is grooved in its periphery to receive said cables, about which the ends of said lines engage as the cable is rotated. Secured on the shaft in is a gear-wheel If, which meshes with a pinion is, secured on a shaft is, extending parallel with the shaft 76 and also journaled on said uprights, and a crank k is secured upon the end of said shaft, thereby permitting the same to be rotated manually with the elfect of partly revolving the cradle.

The operation is as follows: The car-dump is erected at any desired point and with an inclined track-section (not herein shown) leading upwardly to each end of the cradle and registering with the track-rails laid thereon. Said cradle is adjusted in register with said inclined track-section and supported upon the knees B and B, as shown in Fig. 4. The

clamping-beam D is hoisted sufliciently high to avoid contact with the car when moved into the cradle. When the car is in position on the track-rails of the cradle, said clampingbeam D is lowered upon the top of the car and the chains cl are hooked into the eye d of the turnbuckle at each end of said beam and the turnbuckle adjusted up to bring considerable tension upon said. beams, rigidly clamping the car to the cradle. While this is being done operators at each end of the car lower the shaft E into position to be engaged by the ends of the supporting-bars E and E, which are swung upwardly and inwardly and secured on said shaft, as shown in Fig. 2. By means of turnbuckles forming a part of each of said bars the length thereof may be adjusted so that the shafts E at each end of the car lies approximately in alinement with an axis passing through the center of gravity of the cradle and the loaded car. The cradle, with the car, is now ready for operation and by means of the winches at each end of the frame thecrad-le is raised slightly or the knees or supports B B are retracted laterally by means of the hand-wheels 6*, so that the cradle and car are supported Wholly upon the cables f f. An operator upon the platform K now partly rotates the cradle, with the car, by

means of the winch [a provided for that purpose, as shown in Figs. 8, 9, and 10, said winch acting when turned in one direction to swing the cradle to a dumping position, as shown in Fig. 5, and hold the same against any lateral throw occasioned by the dumping of the material therefrom and when rotated oppositely acts to return the same to the normal position. The supports or knees B and B are then moved inwardly by means of the screw-shafts before described to the supporting position and the cradle lowered thereon, and chains (Z are released from their connection with the clamping-beam D and the lines 7& are engaged into the eyes on the top of said beam, which is elevated, as shown in Fig. 4, by means of the crank 72 The strain is released from the cable ff sufiiciently to permit the supportingbars E and E to be detached from the shaft E and said bars are turned laterally outward and the shaft E elevated to the position shown in Fig. 4, permitting the empty car to be run off the cradle. Obviously the operation of unloading the car may be very quickly performed and with slight expenditure of power, owing to the fact that the loaded car and cradle are pivotally supported at or near an axis passing through the center of gravity. It is also obvious that many details of construction may be varied without departing from the principles of this invention.
