IMPROVEMENT IN LEACHES FOR TNNING. I

The Schedule referred to in these Letters Patent and making part oi' the `same.

To all whom it may conce-rn v Be it known'that I, WILLIAM THOMAS HARRIS WHARTON, of Fayetteville, in the county of Lincoln and State of Tennessee, have invented a new and useful Improvement in Leaches for` Tanning; and I do s herebydeclare that 'the following is a full, clear, and

dexact description of the construction and operation of the same, reference being had to the accompanying drawing forming a part of 'this specification, in .which drawing- Figure 1 is a top or plan view of my improved leach for tanning, and

Figure 2 is a section of the same, taken "through the line a: x.

Nature-and Object of this Invention. My invention relates to that class of devices known as tanners leeches; and.

It consists in the novel and peculiar combination and arrangement of certain parts in such a manner -as to dispense with the old system of pumping.

ranged in a square.

The leach or box A,V which is the tirst that 'receivesF the water from afonntain or hydrant, is made, preferably, square, and is provided with a bottom, a, as usual.

Within this leach or box A is formed or otherwise secured, a false perforated bottom, b, resting on suitable hearings or supports, c c, so as to leave or form a space between the two` bottoms.

This false perforated bottom acts as a strainer, preventing foreign substances from entering and stopping the ow of the fluid through the hydrants.

E is a hydrant extending from the bottom a to or near the top .of the leach orbox A, near theY top of which'leach or box, communicating with the hydrant E, is an opening for the reception of a pipe, e, which connects together and communicates with the leach or box B.

One or more apertures may be formed at or near the bottom of the hydrant, between the false perfo rated and real bottoms, so as to allow the iluid to pass down through the` bark into the open space, to rise in the hydrant as the same rises in the leach, so as to conduct it, through the pipe e, into theleach or box B.

These leeches or boxes A, B, O, and-I) are connected together, and communicate with each other through the pipes e e e e, as the leaches A and B,

above described, and are Constr-noted in like manner, each containing a false perforated `bottom and hydrant.

T is a trunk, located near the top of the leaches,

and conveys the liquid from either of the leaches, through pipes, h h h h, into the tanard.

, These four tanks or leachcs are situated two ou each of the trunks T, each being provided with an additional hydrant, P P P P, closed at the top, otherwise the same as those heretofore described.

These hydrants extend from the top to the bott-om of the tanks or boxes A, B, O, and I), and are connected, by means of pipes, h h 7i. le, with the trunk T. These pipes It h h h'conduct the liuid from thetanks or boxes into the trunk T, and from thence the fluid is conveyed out into the tan-yard.

These hydrants I P P P are regulated by means of I gates, which ext-end up above the top of the tanks or boxes, the same being raised or lowered when it isl desired to out oit' the liquid or allow it to flow into the trunk T in order to pass into thevats.

S is the main trunk, upon which the four tanks or boxes rest, running horizontal with the trunk T.

The tanks or boxes communicate with this trunk S by means of tubes or pipes, ll, passing through the bottom of the tanks'or boxes into the main trunk, and which conveys the wasteuid into the junk J, hereinafter mentioned.

` The tubes or pipes llll, which connect the leaches lor boxes with the main trunk, are opened and closed ing within the orifice O O O O.

One end of the main trunk is closed; the other being open, is adjusted or secured 'into au opening or orifice formed in the `junk J.

This junk J is closed at one end and open at the other, and extends linto the ground, so as to be of a size sutlicieut to contain as much fluid as either ot' the leaches or boxes, which, when the waste fluid is conveyed from either ot' the leachcs or boxes, the same may be cleaned out and b e filled up with new bark, and the waste liquor which has been received into the junk and is still of value, may, by means of a pump, be re-conveyed back into either of the leaches or boxes.

The bark is first placedy in the lcaches or tanks A.

Y of the liquor in D is partially exhausted.

B, C, and D inthe space formed between the false perforated and the real bottom. The water or uid is then introduced into the leach or tank A by means of a fountain or hydrant, and, passing through the perforated false bottom, it ascends in the hydrant E as the water rises in the leach o1' tank, until it reaches the opening near the top ofthe. leach or tank, when it is conducted into the leach or box B 'through the pipe e; likewise, from Bto C, and from C to D, and from D it is discharged into the rats until the strength The bark in A is then shifted, the Water is put on at B, and allowed to pass regularly around to A, where it is discharged in'to the vats. The bark in B is then shifted, and the water put on at C, whence it passes to B, and is discharged into the vats. This process is continned, as long as may be necessary, with each succes- .sive leach or box.

If desired to pass the uid through all theleaches, the stop-cocks, which may be arranged on the pipes, may be left open, and the Huid will passthrough the trunk T into the Vat or tan-yard after the uid has been allowed to pass through all the leaches.

The top of the leaches 'may7 be on a level with the ground or tan-yard, and the lnid conveyed to the vats without the use of pumps or labor of any kind. This is due to the additional hydrants and the main trunk, all other leaches heretofore requiring to be elevated, or 'the use of pumps, to force the fiuid out of the leaches or tanks, or the leaches raised so that the fluid would iow to the vats.

XVhcn the leachesl or tanks are placed below the ground they will last many years, at the same time are more convenient. saving a vast amount of labor by dispensing with elevating' the bark in order to get it into thc leaches or tanks.

In all other leaches now in use, the waste liquor is pumped out of them below the ground; by my improvement such is dispensed with.

Having vthus described myinventiou,

Vvvhat l claim as new, and desire'to secure by Let` ters `Patent, is-

O, and D, and communidatingvwith the same throng 1 the pipes or tubes l l l 1, for the purpose described, substantially as set forth. i

5'. The junkJ, provided with an orifice to receive the main trunk S, which supports and communicates with the leaches A, B, C, and D, substantially as and for the purpose described.

To the above I have signed my name this 28th day of May, 1870.
