PATENT LETTERING

CLASS 64: Dispensing equipment.

Patented in the German Empire on July 27, 1883.

The drawing shows in Fig. 1 and 2 the apparatus in section and in the front view, in Figs. 3 and 4 the upper part of the same in section and outline.

The cylinder b is screwed onto the three-way valve α.

It has an outer protective cylinder made of sheet metal, which is soldered to the base c and closed at the top by means of a thread by the cover d.

This cover d presses on a sealing ring e which, like the base c, has screwed-in rubber rings ff which hold an inner glass cylinder g and close it off in an airtight manner.

In the glass cylinder g , hanging from the tabs of the sealing ring e , rotatable on a fixed bolt i , there are two rollers k _t k ₂ , which are supported by a spiral spring / and their peripheries diametrically to each other by two flexible wires r _x r _% are connected to a weight vi , so that with a vertical movement of the weight in, by unwinding the wires ^ ₁ r ₂ on the rollers Ji ₁ k _2, an opposite rotation of the latter must take place.

In the inner part of these rollers are the pawls W ₁ » ₂ , which engage in the ratchet wheels Oi <? 2.

These ratchet wheels O ₁ O ₂ , which are provided with teeth of the same locking direction, together with the worm p form a body which can be rotated about axis i.

The weight m is chosen so heavy that, if unsupported, it sinks to the bottom of the vessel, but if it is relieved by the buoyancy of the incoming liquid, it is lifted again by the tension of the spiral spring.

When the weight m decreases, the pawl H _{1 will} turn the wheel O ₁ and thus the worm in the direction of the arrow, while the pawl O ₂ runs back loosely under the pawl n%; When the weight m rises, the pawl » ₃ turns the small wheel O ₂ and thus the worm in turn turns in the direction of the arrow.

The worm engages in the inner toothing of a ring, which is mounted on the lobes of the upper sealing ring e and the outer edge of which is provided with a scale q visible through the glass cylinder g .

In the lower floor c there is a small valve s in order to hold back the liquid necessary for buoyancy when the weight m is at its lowest level.

There is a small air valve t on the upper cover d so that the pressure never falls below atmospheric pressure when the vessel is emptied.

The mode of action is as follows:

If the cock α is in position a, the inflow from the Fafs as well as the outflow is closed and the weight m is in equilibrium with the spiral /.

If the cock α is turned to position β , the flow is under the pressure prevailing in the barrel

Claims (1)

(approx Y ₄ to ³ / i atmospheres), the liquid in the vessel, the air present therein comprimirend, occurred until equilibrium. Here, the "weight m has been raised proportionally to the quantity that has flowed in, and the scale q has also been rotated. If you now turn the tap to position γ, the liquid exits under the tension prevailing in the cylinder g , the weight m decreases proportionally and the scale q is again rotated accordingly. The result is that, without any manipulation other than that of ordinary tapping, which can be read off every time. For the correctness of the display it is immaterial that both on entry and on Exit is indicated because there is any difference between these two quantities in the Is very small in relation to the desirable control. PATENT claim: Two rollers ^ ₁ k ₂ in the cylinder g, connected by the spiral spring /, are rotated by the latter or by means of the wires T ₁ r ₂ (or equivalent) by the weight m at the same time, equally and in opposite directions to each other, right or left, and through this and through the connection by means of the pawls η _γ n% and the ratchet wheels O ₁ or ₂ with the worm ft cause a one-sided rotation of the latter, proportional to the liquid that has entered or exited the cylinder g.
