CHAIN BASKET Filed Aug. 25, 1936 .E. .E'. CoZe/nww.

33M? @WwM Patented Sept. 7, 1937 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to improvements in chain baskets used for lifting dyed cotton from the containers in which the cotton is dyed, and it consists in the combinations, constructions and arrangements herein described and claimed.

In attempting to lift raw cotton or textiles, such as cotton cloth, from containers in which the cotton is being dyed, considerable difficulty is sometimes experienced due to the fact that the suction between the load and the container becomes so great that either an undue strain is put on the lifting apparatus, or means for breaking this suction must be resorted to in order to free the cotton or cloth and permit the dyed material to be lifted clear of the container.

One of the objects of the invention is to provide a device by means of which suction between the load and the container is prevented.

A further object is to provide a lifting device for dyed cotton and the like, which will bend the load into a condition which facilitates subsequent handling.

A further object of the invention is to provide a strong lifting device which nevertheless is of light weight.

A further object of the invention is to provide a device having the advantages stated above, which is simple in construction, not liable to get easily out of order, and comparatively inexpensive.

Other objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawing forming part of this application, in which:

Figure 1 is a side view showing the chain basket in its relation to a bunch of fabric which is being lifted from the dyed container, and,

Figure 2 is a plan view of the chain basket spread out to receive a load.

In carrying out my invention I provide an inner endless chain 3 which, as shown in Fig. 2, is distended to form a circle. In actual practice this circle may be 18 inches or so in diameter. Spaced from the inner chain 3 and disposed normally concentric thereof is a chain 4 which may be approximately 5% feet in diameter.

Encircling the inner chain 3 are four rings 5 which are slidable with respect to the links of the chain 3. Arranged to slidably receive the chain t are four rings 6, and each ring 6 is secured to a respective ring 5 on the chain 3 by means of a short chain section I. Exteriorly of the endless chain 4 are chain sections 8, each of which is attached to one of the rings 6,

and each of which has at its end a hook 9. The construction is such that a ring section 5, a chain section 1, a ring section 6 and a chain section 8 constitute in fact one radially extending chain having two rings, one to slide on the inner chain 3 and one on the outer chain 6. As will be observed from the drawing, there are four of these radially extending chains indicated in Fig. 2, but it will be obvious that more or less might be used without departing from the spirit of the invention.

In using the device, the basket may be spread on the bottom of the container, as shown in Fig. 2. The cotton goods to be dyed are then placed in the container, and after the goods are dyed the hooks 9 are lifted and brought up around the goods I0, as shown in Fig. 1, and are hooked over the hoisting means which in the present instance is indicated by the chain II in Fig. 1. Now when the chain II is pulled vertically the strands of the chain basket will tend to fold the material inwardly where the chains support it, and at the same time the radially extending chains will slide with respect to the concentric chains so that the lifting basket thus formed may adjust itself to the shape of the load being lifted.

When the material is folded inwardly from the bottom or sides of the container, air of course is drawn in contiguous to the folded portions and thus the suction between the cotton, which is being dyed, and the walls of the containeris broken and strain on the lifting apparatus which might otherwise have occurred is obviated. The shifting of the radiating chains on the concentric portions of the chains tends to obviate undue strain in any particular chain and permits the adjustment of the basket to fit the load as stated.

One advantage of this type of chain basket is a saving in operating time since it is obvious that a second chain basket may be placed in a container without having to wait for the hoist to dump its load and to replace heavy machine parts, as heretofore customarily done.

I claim:

A chain basket comprising an inner endless chain, an outer endless chain in concentric relation with said inner chain, chains radially extending from the inner chain, the inner end of each of said radial chains having a ring received by the inner endless chain, a second ring included in the radially extending chains and receiving the outer endless chain, and hooks carried at the outer ends of each radially extending chain, said endless chains being slidable within the respective rings of the radially extending chain.
