DRAIN-CONTROLLING APPARATUS FOR MASH-TUBS.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed September 23. 1907. Serial No. 394.121.

To all whom it may concern:

Be it known that I, ALoIs AUFRIGHTIG, a citizen of the United States of America, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Drain-Controlling Apparatus for Hash-Tubs, of which the following isa full, clear, and exact description, ref erence being had to the accompanying drawings,forining part of this specification.

My invention relates to means for controlling the flow of wort from mash tubs, and it has for its object to provide an ap aratus whereby the flow of wort may be reac ily rega suilicient quantity of liquid in the mash tub to prevent the flow of the liquid being such that it will be beneath the top of the mash in the. tub, thereby obviating the objectionable feature of cracks or fissures occurringin the mash to the detriment of the quality of wort as a result of the water from which the wort is produced when combined with the .mash, passing too rapidly through the mash.

Figure I is a front elevation of a mash tub and my drain controlling ap aratus. Fig. II is a side elevation of the tu and apparatus with a portion of the tub shown in vertiview of the drain contr'ellin'giipparatus and in part a horizontal section taken on line Fig. IV is an enlarged vertical section taken on line IVIV, Fig. III, and with parts shown in elevation looking in the direction of the arrows crossing said line. Fig. V is an enlarged section through one of the multipleway cocks of my apparatus.

A designates a mash tub, which, as seen in Fig. II is provided with a main bottom B, and a perforated false bottom (1. The main bottom provided at intervals with dips B .(see Figs. II and HI).

1 designates drain pipes attached to the main bottom of the tub at the location of the dips therein of service to provide for the 111010 ready ilow of liquid into the pipes, and which pipes extendoutwardly beneath the mash tu-b t points beyond the wall ol said tub. The drain pipes lead to a receiver 2 to which they are fitted, in order that wort l drawn from the mash tub may be, if so desired, emptied directly into said receiver. In each drain pipe is a multiple-way cock 3, clearly illustrated in Fig V, by which the flow oi wort that passes into the drain pipes is controlled.

1 are riser pipes of a number correspohding to the number of drain pipes and multiple-way cocks, and which are connected to the multiple-way cocks and extend vertically therefrom. I have shown six each of the drain pipes, multiple-way cocks, and riser pipes, but it obvious that these parts may be of series containing other numbers of the parts. 5 is a header to which the upper ends of all of the riser pipes at are connected.

6 is a stand pipe-extending vertically from the header 5 and having communication therewith. This I stand pipe is provided with a cut-oil valve is and a relief cock 7.

8 is a gage tube for indicating the quantity of liquid present in the mash tub and in the pipe 6, and which has communication through a pipe 9 that leads into the bottom of the mash tub and terminates beneath the perforated false bottom (J, provided with a valve 10.

11 designates a steam conducting pipe that leads to the stand pipe 6 and contains a cutoff valve 12 and a check valve 13, the check valve being located between the cutofi' valve and the stand pipe.

1n the practical'use of my apparatus, to produce wort in the mash tub and withdraw it therefrom, the cut-oil valve 6' of the stand pipe is opened to permit flow of water conducted i'rom a suitable source of supply through the pipe, the header 5, the riser pipes 4 and drain pipes 1 to the mash tub into which mash has been introduced, it being understood that to provide for this ilow oi water, the multiple-way cocks Z) are set so that the ilow of water will be delivered into the portions of the drain pipes leading tothe mash tub. After the desired amount of water has been permitted to entorthe mash tub, the cut-oil valve 6 is closed to discontinue the llow oi water to the tub. 'Ihe'multipleway cocks 3 are then so set as to prevent ilow of water from the riser pipes, the header and the stand pipes into the portions of drain above the mash in the tub, one or more when only one of the pipes leading into the 'mash tub, and also prevent flow of water in a downward direction through said drain pipes. The water is then allowed to stand in the mash tub for a sufiicient period of time to produce wort, as is usual. After'the wort has been produced, the relief cock 7 is opened to obviate a vacuum in the stand pi e, and the multiple-way cocks 3 of any or al of the drain pipes 1 may be'so set that said pipes from the mash tub will be delivered directly from the pipes into the receiver 2, as is the common practice in the use of mash tubs. When however, control the draining of'wort from the mash tub in a manner to maintain a level of ligutild t e multiple-way cocks 3 is so set as to cause flow oi wort directly from the mash tub through a drain pipe or drain pipes to one or more of the riser pipes 4 and rise in the riser pipes, header,-and stand pipe to a level corresponding to that of. the liquid in the mash tub. At the same time one or more of the multiple-way the header 5 and the stand ipe 6 to the receiver 2. By this manner 0? conducting the wort to the receiver, it is possible to always maintain a sufficient amount of liquid in the mash tub to cover the mash therein.

It is obvious that by roperly settin any desired number of; mu tiple-way coelrs, a greater or less quantity of wort-may be delivered into the riser pipes, the header, and the stand pipe of the apparatus and that, multiple-way valves is set to deliver wort fronithe header and the stand pipe to the receiver, the flow of wort will be much more gra more'than one cock was set to deliver wort to the receiver, whereas, if it is desired to provide for the delivery of a greater quantity of wort to the receiver in a specified time, more than one of the cooks may be set to accomplish delivery to the receiver. Byproviding the gage tube 8, I furnish means whereby the operator of the apparatus may be constantly in. possession of information as to the level of wort in the stand pipe 6 and in the mash tub, thereby enabling the operator to properly regulate the multiple-way cocks in order that the flow of wort to the header and stand pipe, and from said header to the receiver 2, may be controlled as desired, for the purpose of maintaining the conditions contemplated in the use of my apparatus. to the apparatus in order that it may be conveyed into the mash tub to heat the water therein, during the production of wort, and also to permit the introduction of steam into the drain apparatus at a pressure medium to the wort withdrawn through i it is desired to cocks 3, other than those previously set, is set to cause delivery; of the wort from dual than it would if The steam pipe 11 serves to conduct steam eva es blow out deposits that may become accumulated in the pipes of the apparatus and the multiple-way cocks, and also at thebottom oi the mash tub. The check valve 13 in the steam c'ond preventing flow of water or wort from the stand pipe 6 into the said steam conducting l pipe in the event of the cut-ofi valve 12 being accidentally left in an open condition;
