Description
UNITED STATES PATENT` OFFICE.,
IMPROVEMENT IN TANNlNG-VATS.
- Specification forming part of Letters Patent No. 122,157, dated becember, 1871.
To all 'whom t may concern: i
Be it known that I, JOSEPH W. GOBUEN, of East Walpole, in the county of Norfolk and State of Massachusetts, have invented an Improvement in Tanning-Vats; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this A specification, is a description of my invention sufiicient to enable those skilled in the art to practice it.
My invention relates to an improvement in tanning-vats, which improvement is designed to accelerate the tanning process by creating a circulation ofthe tannin and preventing its deposition, and thereby subjecting all parts of the Skins equally to the action of a liquid oil equal strength.
My invention consists, primarily, in combiningand y y.
a a denote the side walls of the vat; b b, horizontal cross-bars at the bottom of the vat, which bars may terminate with side inclines c d (extending from the bars to the Side walls, or to verl tical partitions e) and with `center inclines f. Under the bars b is the horizontal wheel g, hav; ing radial or radially-curved blades or spokes h fixed to and projecting from a hub, i, on a vertical shait, k, journaled in Suitable bearings. This shaft is driven by any suitable power, that shown in the drawing consisting of a bevel-gear, Z, into which meshes a pinion, m., On a sha1t,u, driven by a crank-handle, o.
The vat being charged with liquid and tannin and iilled with skins, (suspended upon suitable rack-bars at the top of the vat,) rotary motion is imparted to the Wheel g, and this motion drives the liquid centrifugallyagainst the inclines and against the side Walls, causing it to iiow upward, and creating upward and downward currents, thereby keepin g the tannin in circulation throughout the liquid and the liquid in circulation around and over the surfaces Ot' the skins.
The partitions e form vertical spaces q, through which the liquid is driven upward, said partitions not reaching to the top of the vat, and the liquid consequently iiowing inward over their tops tO- Wardthe center of the vat.Y
I claim- Ahorizontal liquid-circulating Wheel, g, in combination with a tanning-vat.
Vitnesses: `JOSEPH W. COBURN.
