LIQUID-AGITATOR.

l Specification of Letters Patent.

Patented .Tune 9, 1908.

Application filed September 28, 1907. Serial No. 394,999.

To all whom it may concern:

E-gBe it known that we, JOHN VALIQUETTE and MICHAEL VALIQUETTE, both of the village of Cummings Bridge, in the county of Carleton, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Liquid-Agitators, of which the following is a specification.

Our invention relates to improvements in liquid agitators and the objects of our invention are to provide an agitator, particularly adaptable for circulating the liquid and lime in the tanning process, whereby the labor hitherto necessary to accomplish this matter 1s saved and the process is carried out with a decreased amount of lime and it consists essentially of a vat having means thereon for vertically suspending the hides, a continuous chain provided with paddles extending along the ends and bottom of the vat, and partitions preventing the hides from contacting with the chain, all as hereinafter more fully set forth and described in the accompanying specification and drawings.

In the drawings, Figure l is a sectional view through the agitator. Fig. 2 is a top view of the same. Fig. 3 is a perspective view of the agitator chain. Fig. l is a perspective detail showing the mode of suspension of the hides.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the vat of the usual construction set on a suitable foundation B. Along the two sides of the vat, piping c and b run being connected at the extremities to the side of the vat. The hides o are suspended vertically from this piping by means of hooks d connected to the hides and extending over the piping.

C and D are two endless chains supported on two sets of sprocket Wheels e, f, g, h, and t', which are supported on shafts y', Ys, l, m and n.

The lower shafts m and n are journaled in the sides of the vat and the upper shafts y', c and Z are journaled in suitable bearings supported on standards, o, p and q, which are secured in the foundation B. The outer shaft Z has a pulley r connected thereto, by means of which the two chains may berotated and the shaft has a suitable form of tightening device s connected thereto.

Connected to both chains and extending substantially normal thereto, are a plurality of paddles t which operate to stir the liquid or mixture of liquid and solid in the vat.

These paddles and the chain itself may be of any desired construction. The connecting means between the two, which I have illustrated in the accompanying drawing, comprises outwardly projecting lugs u, integral with the chain and which are bolted to the paddles.

To prevent the hides swinging laterally and striking against the chain, we provide partitions E and E, extending across the vats and reaching to the bottom of the hides.

There are also provided guard bars G at the bottom preventing the hides touching the chain as it runs along the bottom, should they become disengaged and drop down.

It will thus be seen that we have devised an exceedingly cheap and simple form of agitator, which may be used for a variety of purposes. In operation, the chain is rotated continuously, insuring a complete circulation of the liquid. Particularly is it adaptable for the purpose of circulating the liquid and lime in the tanning process, as in this case, the hides being hung vertically are reached on all sides by the liquid which is in constant circulation. This is a considerable advance over the old method of treating with lime in which the hides were simply piled in a vat and the mixture of lime and liquid poured thereon.

While the invention has been described herein with great particularity of detail, yet it will be readily understood that in carrying out the construction of the same, changes may be made therein without departing Inaterially from the spirit of the invention.

What we claim as our invention is 1. An improved agitator for mixtures employed to treat solid substances, comprising a plurality of chains extending into the mixture, paddles thereon, and means for preventing the solid substances contacting with the chain, as and for the purpose specified.

2. An improved agitator for the liquid employed to treat hides comprising a suitable vat, a chain running along the ends and bottom of the vat, means for supporting and rotating the same, paddles on the chains, and partitions at each end preventing the hides contacting with the chains, as and for the purpose specified.

n improved agitator for treating hides comprising a suitable vat, means on the side thereof for suspending the hides vertically in the vat, chains extending along the end and bottom of the vat, means for supporting and rotating the same, paddles on the chains and partitions preventing` the hides Contacting with the Chains, as and for the purpose specified.

4. An improved agitator vfor tanningl proC- esses, ComprisingI a suitable vat, bars extending along the side of the same, to which the hooks on the hides are adapted to be oonnected, chains extending along the ends and bottom of the vat, means for supporting and rotating` the chains, paddles on the chains,l

and partitions preventing the hides Contacting with the Chains, as and for the purpose specified.

Signed at Ottawa, Province of Ontario, this 23rd day of September, 1907.
