VILLIAM GREISSER, OF GHCAGO, ILLINOIS.
' MASH SPECIFICATION forming part of Letters Patent No. 368,788?, dated August l23, 1887. Application filed September 10, 1886. Serial No. 214.062. (No model.)
To all whom it may concern.-
Beit known that 1,-W1LLIAM Gnmssnn, a subject ofthe Emperor of Germany, residing it Chicago, in the county of Cook and` State of llinos, haveinvented a certam new and useful Improvement in Mash-Tubs; and I hereby declare the following td be a full, clear, and exact description of the same.
My improvement relates particularly to the o valve portion of mash-tubs. I
Sometimes mash-tubs'are provided with an opening for the dischargeat the proper time of the mash, which openingv is covered by a hinged lidraised within the tub, to permit the )5' 'discharge of the contents, by means of a bar or any form of suitable lever sufficiently handy for the purpose. These means ,are not only crude,bntit sometimes reqnires'the expenditure ot' considerable time and patience to find zo the hinged lid when covered by the contents of the tub, and, when found, to effect its rise by means of the implement used for the purpose. Another construction known to me of the discharge-valve portion of a mash-tub involves an outwardly-opening hinged valve, (in this respect resembling my improved construction, as will hereinafter appear,) which,A however, is operated from underneath the tub,
l requiring the operator to take aposition un- 3o derneath it, where he is in the way of the discharging contents; and this construction also provides the valve below the upper surface of the false bottom of the tub, whereby a recess is formed which receives and retains a part of thefwort, instead of permitting it all to be draigvn off in the usual manner before discharging the residue or grain, thereby necessitating the discharge with the grain, on opening the valve'for the purpose, of the wort retained in Besides, the forni of valve last referred to-does not, owing to the obstruction afforded by the mechanism l for operating it, permit the provision of a i closed spout or flange around the discharge-A opening. I provide for the purpose an outwardly-opening valve, which is flushed when il closed with the upper surface of the bottom', and means for controllingit beyond and out of the way of the valve-opening. l
My invention consists in the general construction of my improvement; and it further consists in certain details of construction and combinations of parts, all as hereinafter nbre fully set forth.
In the drawings,Figu re representsa broken portion, in section, of the base of a mash-tub provided with my improvement. Fig. 2 is a. sectional view taken on the line 2 of Fig. 1, to one side of the bearing shown in the lastnamed figure, viewed in the v'direetionof the arrow, the roller, however, being shown in elevation; Fig. 3, a broken sectional view showing a detail of construction; Fig. 4, a. reduced pian view of the valve, showing parts below itin dotted lines, and Fig. 5, a broken plan view, with the cover removed, of a mashtub with some of its connect-ions, all of wellknown construction and provided with my improved valve device.
Ais the bottom .(usual'ly iron)vof themash tub A', and B is the false bottom above the bottom A, the part-s A and B forming the bottom of the tub. To one side of the bottom A B is a suitable circular opening covered by a valve, C, comprising a-circular plate, r, having a lateral flaring flange, q, provided ou the one s'i-:e with a hinge-knuckle or cylindrical bearing, p, to receive the supporting-pin p of the plate r, the pin p being sustained by thc frame D,in contourlike the plate r. The flange q around the plate r is bent upward, as shown at x, Fig. 1, to receiveashoulder, o, provided around the frame D on itl inner side,and enters a coincident recess, n, in such frame, which, at'
the hinged side of the valve, forms a housing or shield, as shown, for the knuckle p, the frame D being bolted upon the upper side of the bottom A, near the edge'of the dischargeopening, and forming Yin the discharge-open ing a wall between the false bottom B and bottom A.
'E is a frame bolted to the under side ofthe bottom A, preferably, as shown, by the same bolts which sustain the frame D, of which it forms practically a continuation, being ofthe same general contour, except at its rear side, which is straight, as shown by the dotted lines in Fig. 4, and affords, among other purposes, hereinafter described, a flange surrounding the discharge-opening and means upon which to adjust the spout F.
G G are bearlngs, extending from the center 1 of the under side ofthe plate r, for the roller H,
serving a purpose hereinafter described.
. ing around the circular portion of the valve,
though packing t may also be provided, if desired. The form of the ange g on the hinged side of the valve C and of the adjacent part of the frame D, together with the knuckle p, effectually seal the discharge-opening at that part of the valve, though packing t may also there be provided.
Removal or withdrawal of the bar I from within the frame E permits the valve C to swing open in a downward or outward direction, as'indicated by the dotted line af, on its hinge p p and allow the mash to discharge through the spout F. The .withdrawal ofthe barl is eifectedr by turning in the proper direction a stationary screw, K, supported near one end in a bearing, m, bolted to the under `lside of the bottom A,vbcyond or away from the valve device. The screw works at its opposite end in an internally-threaded ange or collar, m', on one side of the bar I, which is supported beyond the frame Ein a bearing, l, bolted to the under side ofthe bottom A, and moves between friction-rollers k and lc aud at its beveled extremity upon a. friction-roller, t'.
4 faceof a web, r', on the under side of the plate r of the valve C, whereby the latter is raised or swung back toward its closed position,
wherein it is iiush on its upper surface with' the corresponding surface of the false bottom B.
The bar I being of necessity, owing to the form of the valve,to the various bearings,and the pulley L, some distance below the bottom A, it naturally will not remain in contact at its extremity with the under surface'of thev web r when the valve in its rise assumes an angle which takes the web out of the path of the bar; hence I vprovide the roller H at or near the center of the valve, with which the bar I in its forward course comes into contact at its beveled end y, and toward which the Letters Patent, is y which passes through pipes g,communicating y with such chamber from the under side of the bottom A, along which they extend to aclosed cylinder, M, communicating by a pipc,f,with the'brew-kettle, (not shown,) and by a pipe,
f', with a pump, (not shown,) and provided with .an opening, e, at which to 'introduce clean water for rinsing purposes. The communication otthe `pipes g with the cylinder M is controlled by suitable cocks, d. The pump referred to serves to force they wort back into the mash-tub as frequently as is necessary to relieve it of turbidity, and when suiciently clear it is admitted through the pipef into the brew-kettle. l
What Iclaim asnew, and desire to secure by 1. In a mash-tub, the combination of the bottom provided with a discharge-opening, a frame, E, at the discharge-opening on the under side of the tub-bottom, a downwardlyopening hinged valve, C, for the dischargeopening, a horizontally-reciprocating bar, I,l supported in the frame to support and secure the valve when closed and release the same to open it, and means, substantially as described, connected with the reciprocating bar for actuating it from beyond the tub, substantially as and for the purpose set forth.
2. Ina mash-tub having a bottom, A, and a false bottom, B,forming the bottom of the tub, provided with a discharge-opening, the combination, with the bottom A B, of a frame, D, forming a wall in the discharge-opening between the bottom A and false bottom B, and having a housing and a shoulder, o, a downwardly-swinging valve, C, for the dischargeopening, hinged to the frame D, and comprising a plate, r, having a web, r', a liaring flange, g, a hinge-knuckle, p, and a ange, z, a friction-roller supported on the under side ofthe plate r, a frame, E, below the bottom A, forming a flange around the discharge-opening, a bar, I, supported to extend through and across the frame E and beveled toward one extremity, friction-rollers i, k, and k', and ay station in y Letters Paen No. 368,887
