- SPECIFICATION forming part of Letters Patent No. 780,401, dated January 17, 1905. Application filed August 11, 1904l Serial No; 220,404.

To a/ZZ whont w may concern:

' and its object is to provide an-apparatus of such class wherebya mass of material may be elevated, transported, and dumped lat any point desired.

The invention further aims to provide a hoisting apparatus particularly adapted for use in removing a mass of dyed material from a dyeing-machine, transporting the mass to any point desired, and permitting of the dumping of the mass on either side of the support or carrier.

Although, as stated, the apparatus is particularly adapted for dyeing-machines, yet the same can be used for any purposes for whichit is found applicable.

' The invention further aims to construct a hoisting apparatus which -shall be simple in its construction, strong, durable, efficient in its use, and comparatively inexpensive to set up.

With the foregoing and other objects in view the invention consists of the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended. Y

In describing the invention in detail reference is had to the-accompanying drawings, forming apart of this specification, and wherein like reference characters denote corresponding parts throughout both views, and in whichi Figure 1 is an end view of one form of an apparatus constructed in accordance with this invention with the support or carrier for the material attached thereto; and Fig. 2 is aside elevation of the apparatus, showing the support or carrier for the material in full and v dotted lines,the support or carrier being shown in tilted position in dotted lines.

In the drawings the elevating element of the apparatus for elevating and lowering the support or carrier for the material is shown as a chain hoist; but it will be stated that the elevating element for raising and lowering the support or carrier may be of any other suitable form, such as a pneumatic, steam, or

y hydraulic device.

Forl the purpose of showing the adaptation of the'invention the same is illustrated for use in connection with the vat of a dyeingmachine; but, as heretofore stated, the apparatus is adapted for whatever purpose it may be found applicable.

Referring to the drawings by reference char- 4acters, 1 denotes the vat of a dyeing-machine, and 2 the support or carrier. As shown, said support or carrier consists of a perforated cir- 'cular plate. The vat 1 is shown in dotted lines in Fig. 1, while the plate 2 is shown both in dotted and full lines. In dotted lines the plate is shown as supported in the bottom of the vat. In full lines the plate is shown as being removed from the vat. The plate 2 is provided with a series of eyes 3, to which is attached the lower end of the flexible connecting members-as shown, chains-four in number and designated by the reference characters 4, 5, 6, and 7. The flexible connecting balancing members suspend the support or carrier on an even balance, thereby enabling Vthe tilting ofthe support or carrier in either direction, so as to discharge the mass of mal terial from either side of the support or car-v rier. The balancing members, as shown, consist of a pair of chains 13 14; but it will be stated that said members may be a wire rope, cable, or the like.

The balancing members 13 14 have at their lower ends hooks 15, which are adapted to engage in the. openings 16, formed in the plate 2 near the edge thereof, said openings 16 being arranged diametrically opposite each other. As shown, the upper ends of the flexible members 13 14 are attached to the hooks 17, carried by the frame of the trolley 11; butit will be stated that the upper ends of the flexible members 13 14 can be connected at other points and yet perform their function. For example, they may be suspended from the ceiling or rafter at the point where the load is to be dumped.

The operation of the apparatus is as follows: After the mass of material has been dyed the connecting members 4, 5, 6, and 7 are attached to the hook 9. The elevating and lowering element is then operated, which ele- Vates the support or carrier 2 until it clears the vat 1. The support or carrier, with the material thereon, is then run or transported to any desired point through the medium of the trolley 11 and track 12. When it is desired to dump the mass of material off the support or carrier, the balancing members 13 14 are then connected at their lower ends to the support or carrier 2.' The elevating and lowering element is then operated to lower the support or carrier, 2 until the strain or weight of said support or carrier and mass of material is on the balancing members 13 14. It will then be seen that the support or carrier 2 being evenly balanced can be tilted or tipped in either direction, thereby removing the dyed material. Before the support is tilted or tipped in one direction the upper ends of the connecting members 4 5 are removed from the hook 9. 1f the support or carrier is tilted in the opposite direction, the upper ends of the connecting members 6 7 are detached from the hook 9. After the material has been dumped from the support or carrier the pair of connecting members which hasbeen detached from the hook 9 is then attached to said hook and the elevating and lowering element is then operated to raise the support or carrier, which causes a slack in the balancing members 13 14. These latter members are then detachedl from the support or carrier 2 and the latter brought into position again for another dyeing and removal of another mass of material.

It is thought the many advantages of ahoisting apparatus constructed in accordance with the foregoing description, taken in connection with the accompanying drawings, can be thoroughly understood, and it will furthermore be evident that changes, Variations, and moditications can be resorted to without departing from the spirit of the invention or sacrificing any of its advantages, and 1`therefore do not wish to restrict myself to the details of construction hereinbefore described and as shown in the accompanying drawings, but reserve the right to make such changes, variations, and modiiications as come properly within the scope of the protection prayed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isw- 1. A hoisting apparatus involving a track, a trolley suspended therefrom and traveling thereon, an elevating and lowering element suspended from the trolley, a carrier detachably connected with said element and capable of being tilted in opposite directions, and a pair of balancing members connected at one end to said trolley and at their other ends detachably connected to said carrier, to permit of the tilting thereof in opposite directions.

2. A hoisting apparatus involving a traveling member, an elevating and lowering element suspended from said member, a carrierplate detachably connected with said element and provided with a pair of diametrically opposite openings, said plate capable of being tilted in opposite directions, and a pair of balancing members having their upper ends secured to a suitable support and their lower ends engaging in said openings, said balancing members adapted to suspend and act as a pivot for said plate when tilting the same in opposite directions.

1n testimony whereof l have hereunto set my hand in presence of two subscribing witnesses.
