Specification of Letters, PatentNo. 8,183, dated June 24, 1851.

To all whom it mag/concern: i

Be it known that I, "JOSEPH WiiiGi-rrfof Vaterloo, in the `countylof Seneca and `State of New York, haveinvented new"and useful improvements the apparatus for l1 forming the` mash from raw or `preparediiieal `or grain and formixing, cooking, andcooling the same for the purposes of distillingiand brewing; andfdohereby dec-lare that the,

following is a full, clear, and exact descriptionof the saine, reference being had to `the feedingin the meal zor grain,` andFig. 5, is

a regular plan, andiFig. 6, an inverted plan (or view from underneathlof thesame. `The same letters of reference denote similar parts throughout each of the` several figures.' i a The nature of myjinvention consists in the combined use of a closed cylinder, in which is `a revolving' shaft, having beaters, and

` moving at a qiiickvelocity, the meal or grain being admittedby a self regulating hopper,

in proper proportionsto` the supply of heated water, `and uniformly scalded and mashed in small `quantities; the "mash,

thus rapidly formed, continualljT passing off into a cooler having a large metallic, or other, cooling surface, and which maybe supplied `with a current of cold air, or water, it being providedwith revolving beatersl for stirring up the mash against the air;

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, A, is the stationary mashing cylinder having a feeding funnel B, and delivery outlet pipe C; it is shown horizontal, but may be setatany suitable position or angle. a, a, are rods for bracing the cylinder, one end or cover of which, is made removable, by unfastening the nuts screwirg on the ends of the rod a, a. j

D,is the inashing staff or shaft, having projecting beaters b, 79, Z9, of any suitable number and sha-pe', and arranged around the shaft D, in rows, or in any regular, or irregular, manner; The cylinder A, A, may also have beaters projecting from its iii- Fig. 3, is a `longitudinal section.

terior, between which the revolving beaters 6, b, b, might work orpass.` The shaft D, and its beaters b, b, b, are set in rapid motion by handle E, or pulley F, drivenby steam or other power. `The cylinder A, `A, rests on an upright G,`or may be Otherwise supported to keep it stationary..

H, isa hopper, through which the grain or meal is fed, itis i'ittedvvitli two plates c`c`, at its'bottom, situated a short distance apartpand having radial openings d, e, the

one opening CZ, in the top plate o', and t-he opening e, in the bottom plate c, being positioned on opposite sides of the center, or one,

on the left, and the other on the right hand side, of the hopper H.` i

f, the shaft I,` wo-rks throughf the plates 0,0, and has arms g, g, of any required number, branching from it, bound by a ringh, v,

which together with the arms g, g, workbe-` I,is an upright shaft driven by "pulleyr1 tween the plates c, c, the spaces formed. by i 1the arms g, g, constituting so many buckets, into which the meal Orgrainpasses from the hopper through the opening Land which isldelivered into the funnel Enduring the revolving motion ofthe shaft through the opening e.

M, (Fig. 2,)

the mashl runfroin the outlet C; it may he made for `or lined with metal, aiidbe of any suitable size or shape, it may consist of one, or more,` say, two curved chambers as shown in the drawing having a bridge K, and having its interior surfacemade either plain, Oi' with ribs, or other projections, and may be seated in` another vessel," containing, or be sur- ;rounded by, water, which may be admitted is a pipe for conducting" heated water into the cylinder A, to form" through the openings z', z', or be madeto cir` l lculate aro-und the coolerl J, J, thelconstruction and form of which, if of metahbeng so arranged as to present a large metallic cooling surface in proportion tothe quantity of mash it contains.

L, L, are barrels revolving in opposite directions and driven by the pulleys Z, Z, The barrels L, L, may be, made with a hollow passage through their center (as shown in Fig. 2,) for the flow of `cold water to aid in cooling the mash. j

m, m., m, m, are projecting pins, or beaters, a

attached to the barrels L, L, they may be arl ranged around the barrels in any suitable way, and be of any propersizeor shape, and made either hollow or solid. Any number of barrels L, L, may be used, or one only, if preferred, according` to the size and shape of the cooler J, J.

72 n., (Fig. 2) are outlets for the mash when sufliciently cooled, and which, while \the mash is being made, or cooled, are shut up by plugs.

The operation is as follows. The meal or grain being fed into the hopper H, and the several pulleys f, F, Z, Z, being set in motion, the .buckets formed by the arms g, g, attached to the shaft I, receive a portion of the meal or grain through the opening CZ, in the top plate c, delivering the same through the opening e, into the funnel B, and hence to the cylinder A, A; heated water being simultaneously introduced, in a regulated proportion, through the pipe M; the heated water scalding the meal or grain, which by the rapid motion of the beaters Z), b, Z2, Z2, is quickly mashed, and mixed up or incorporated, as it were, with the water; the mash, thus formed, continually passing off through the outlet- C, into the cooler J, J, where it is stirred, and thrown up against the air, by the revolving beaters m, m, m, m, for the purpose of more rapidly and eifectually cooling the mash, in addition to the arrange ments, already described, for that purpose, in the form of the cooler J, J, passages through the barrels L, L, and current, or surrounding vessel, of water. It will be seen that the delivery of meal or grain to the cylinder A A, is regulated, in its proportion, to the speed of the masher or beaters Z), b, Z9, b; for should the velocity of the prime mover be changed, the several pulleys F, f, Z, Z, would each be proportionally affected, and the buckets or spaces formed by the arms g, g, receiveand deliver, only so much meal or grain, as the speed of the beaters Z), ZJ, Z), Z), are capable of mashing; the supply of heated water forming the mash, being also proportionally regulated.

The following are a few of the advantages of my invention over the ordinary process of mashing. The meal or grain being mixed in small quantities within a closed cylinder as described, the mash is more thoroughly perfected ,and mixed, than in the ordinary Y large open mash tun; the meal or grain being thoroughly incorporated with the water, scalded and mashed; lumps in the mash are lessliable to form when thus mixed, and a lower temperature of water may be used for lforming the mash, but producing an equal, and uniform, scald, as the quantity operated j on, at the same time, is but small, hence, but

little loss by radiation of heat occurs; and lconsequently, not only is the virtue of the meal or grain preserved, but the injury susttained by the use of a high temperature of .water, as in the ordinary mash t-un, by overscalding and under scalding parts, is avoided. A smaller prime mover will suffice to form the mash. Room is considerably economized and the apparatus more easily kept sweet and clean. A quick and effectual condensation is procured and when mashing for the purposes of distilling corn meal without the usual mixture of English or small grain, will be found, by this arrangement, to produce good and abundant spirits, as the mash by this means is bet-ter mixed, scalded and icooked whereby raw mea-l may be used; and

for the purposes of brewing the prepared grain, or malt, is similarly operated on.

I/Vhat I claim as my invention and desire to secure by Letters Patent is 1. The employment of buckets formed by the revolving arms g, g, working within the hopper H, for delivering the grain through suitable openings cZ e, into, and operatingv in combination with the mashing cylinder A, A, having an outlet C, (or outlets) for supplying'the cooler J, J, substantially as shown and described.

2. The use of a mashing cylinder A, A, having beaters within it and operating in combination with a cooler J, J carrying any number of barrels or shafts L, L, fitted with projecting pins m, m, m, m, essentially as shown and described, for the purposes set forth.

In testimony whereof I have hereunto signed my name before two witnesses.

JOSEPH VRIGHT.
