PATENT OFFICE.

The present invention relates to such fermenting tub or yeast tub coolers, which, two cooling coils, one on one, the other on that other end of a balance beam is suspended movably, thereby lifted alternately and be lowered so that the cooling water is alternately admitted into the first line and drained from the second. The subject of my invention is a device through which the inflow and outflow of the cooling water is regulated.

In the accompanying drawing, a yeast cooler provided with the new device is shown in side view. The balance beam a , which is rotatably mounted on a column S by a ° , carries one cooling coil b on the left and the other cooling coil b \ below which the cooling vats c respectively. c ^{1 are} set up. Above the balance beam α , a vessel d is attached to the column S , into which the cooling water is fed through the pipe f. The vessel d is respectively through a hose g. g ¹ with one of the vessels b ^x respectively. by in connection, which the latter are attached to "the cooling coils bb ^l " and hang movably on the balance beam.

Where the hoses gg open out d in the Speisegefäfs ^1, the latter valves are in the ground d ¹ d provided ^, which are alternately opened and closed to the cooling water soon b in the vessel, ^x snake b and soon by in the vessel, to direct the serpent b ^1. This opening and closing of the valves d ^l df ² takes place in the following way:

Die'Zunge α ^{1 of} the balance beam plays between the prongs of a forked down, rotatably attached to the column 5 double-armed lever h and turns the lever h alternately to one side and the other.

This movement of the lever h is transmitted to a wheel / c, which is rotatably mounted on the column S above the feed vessel d, by the upper arm of the lever h against one of the two pins protruding forward from the rim of the wheel k k ^l k ² acts and thereby turns the wheel soon to the right and now to the left. The wheel k is with the two above-mentioned flap valves d ¹ d? each connected by a chain k ³ A *, the length of which is so dimensioned that when the lever h assumes the position shown, the valve d ^{1 is} open so that the cooling water flows into the vessel b ^{x of} the snake b , on the other hand the valve d is closed.

So that now, when b ^{x is} filled, the queue b can lower itself, by must be emptied. This takes place at the time of filling the vessel b ^x in that a valve v ¹ provided in the bottom of the vessel by , which closes the upper opening of the coil b ¹ , is opened. This valve v ¹ is connected by a chain \> y to a point located between the pivot point of the balance beam α and the suspension point of the vessel by , and the chain v ¹ is chosen to be just long enough that it is stretched and the valve v ¹ opens when as a result of the lowering of the vessel by with its snake b ¹ the angle between the center line of the vessel by and the center line of the balance beam BEZW. the distance between

see the two attachment points of the chain v ^y on the balance beam and on the valve.

The cooling water of the vessel by then flows into the coil b ¹ and displaces the water located therein, which has absorbed heat from the liquid in the vat, through the riser pipe b ² towards the outside.

In the bottom of the vessel b ^x , as in by, a valve ν is provided and this is automatically closed at the time when the snake b goes up because the chain ν ^x by reducing the distance between its attachment points on the balance. bar and on the valve is slack and the valve ν releases.

Is the vessel b ^x filled and the vessel b? emptied, the snake b sinks downwards, while the snake b ^{1 is} raised, and the reverse process now occurs; Lever h and wheel k are turned to the other side, valve d ² opened, valve d ¹ closed, valve v ^l closed and valve ν opened.

In order to safely reverse the lever h through the tongue of the balance beam, a running weight a ' ^{2 is} provided on the balance beam, which can be displaced on a rod α attached along the front side of the balance beam. At the moment when the balance beam has crossed the horizontal position, this weight slides quickly from one end of the balance beam to the other and its weight increases the weight of the filled vessel b * (by) with its snake b (b ¹ ) respectively. the weight replaces the water which has already flowed out during the last part of the downward movement of the snake b (b ^x ) through the partially opened valve ν (ν ¹ ) , so that the water needed to be turned over. of the lever h and to open the valve d ^l respectively. d ' ¹ required force is obtained.

The device described can also be used in such a way that cooling water is supplied to only one coil, in the event that only one cooling tub is to be used. For this it is only necessary that the chains k ^s (k *) and v ^x (vy) of the valves d ¹ (d ² ) and ν (V ¹ J depend on the wheel k or balance beam α and the unused cooling coil with it so much water is polluted that it can lift the other cooling coil when its vessel b ^x (by) is emptied.

It should also be noted that the above-mentioned wheel k, which actuates the valves d ^l d ² , can also be replaced by a lever.

Claims (1)

Patent claim: On cooling devices for fermentation and yeast vats, in which the cooling coils are moved by means of the cooling water used, the reversal of the cooling water inflow in such a way that a tilting wheel (or rocker arm) ^{through the tongue a l} of the balance beam α carrying the cooling coils by means of a lever h is bethätigt k which, d by traction organs d in Wasserzuflufsbehälter arranged valves ¹ d ^{2 are} connected, these alternately opens and asleep while alternately at the upper end of the cooling coils in the containers b ^x by located valves vv ^l by attached to the balance beam traction organs be closed and opened.
