CLASS β4: dispensing equipment.

Patented in the German Empire on July 3, 1885.

The innovations in beer - air pressure pumps, which are the subject of the present invention, which are operated by water pressure, on the one hand, refer to the reversing mechanism for the four-way cock to be used, on the other hand on the peculiar construction of the piston tensions, which at any time an easy setting and regulation of the piston seals without Enable opening of the cylinder.

The attached drawing shows:
'Fig. Ι the side view,

Fig. 2 the front view,

3 shows the cross section of the pump;

Figures 4 to 11 show details.

The pressurized water flows in through the pipe a , while the used water flows out through the pipe b . The tubes α and b lead to a four-way valve c; the same is shown in Figs. The cock plug or the wing bolt d, FIGS. 7 and 8, which takes the position of FIG. 4 on the one hand and the position of FIG. 5 on the other, moves in the tap. In the position of the pump shown in FIGS. 1, 2 and 3, the wing bolt d is in the position of FIG. 4. The pressurized water flows through the pipe α at a ^l into the cock c, goes through the same and the pipe e after the upper end of the cylinder f and drives the piston downwards in the same. The water under the flask fiows through pipe g and tap c at b ¹ to pipe b and is carried on through the latter.

The piston in cylinder f is attached to bridge i ¹ , while the piston in cylinder h is connected to bridge i ¹¹ . Furthermore, the rods k ^IH k ^{un are} attached to the bridges i ¹ and i ^11. If the piston is accordingly pushed in / down, the rods k ¹ to k ^IUI and thus also the piston located in the cylinder h move downwards.

The two cams fastened to the rod k ^un drive the lever Z, to be precise the same is pressed downwards by the upper cam when the rod k ^{IHI descends.}

This lever I is attached to the disk m . The lever η is also attached to the end of the wing bolt d. Now enters the lever · Z to the horizontal position, so there is the rod in a vertical position 0, and the p defined in the cylinder spiral is with progressive movement of the rod ο over to the left drive.

Since the rod 0 is attached to the disk m , with this jerky movement the disk m will throw the lever η to the right due to the cutout located on its circumference and the wing bolt d moves from the position of FIG. 4 to that of FIG. 5.

In the meantime the pistons moving in cylinders f and h had come close to the bottom of the same. The air that was in the cylinder h is driven through the double valve q ¹ to the air pressure vessel, while air has passed through that q ¹¹ into the space above the piston. By reversing the wing bolt d , the movement is now opposite. The pressurized water passes through the pipe a

and the cock c to the pipe g and through this under the piston in the cylinder f; this and with it the piston located in the cylinder k , as well as the lever / are driven upwards; the water above the flask in f flows away through pipe e, tap c and pipe b ; the air above the piston is driven through valve q ¹¹ to the air pressure vessel and air flows through valve q ¹ into the space under the piston in h until the wing bolt d is reversed again. From FIGS. 9 and 10, the two end positions of the disk in with the lever η and the rod 0 can be seen. 11 shows the construction of the double valves q ¹ q ¹¹ . The spiral located in the cylinder p can be set by turning or turning back the piston driven by the same (it can also be removed and replaced by a new spiral). Because the lower end of the rod is guided ο vertically, the force of the jolt caused by the spiral is moderated.

The construction of the pistons moving in cylinders f and h is shown in FIG. The pistons consist of two prized leather sleeves r, in which the rubber washers s are inserted. A wrought iron disk t is placed on each of the two end faces of the piston thus assembled. The rod u goes through the piston and is riveted to the iron disk on the other side. At its other end, the rod u has a thread onto which a nut is screwed beyond the bridge. When assembling the pump, the rod u is pushed through the tube ν . The length of this tube is equal to the distance between the bridge and the one iron disk t.

While in the previous devices the cylinder had to be opened and the piston mostly had to be removed whenever a leak occurred, in the present construction the piston seals can be adjusted and regulated at any time by means of the nut, in that the rubber washers s the leather cuffs when the nut is tightened Press r firmly against the cylinder wall.

Claims (2)

Patent Claims: 1. To move the four-way valve intended for controlling air pumps for beer lines, a disc rotatable around the tap housing (m in Fig. 2), on whose lever-like arm (I) the stops of a control rod (k ^Ilu ) act and thereby the rotating movement of the disc (Initiate mj , whereby a spring is tensioned by a rod engaging the disk (o in Figs. 2 and 3) which, after exceeding its greatest compression, in turn acts drivingly on the disk and allows it to quickly cover the second part of the prescribed path if this disc is used in conjunction with a lever (n ) fastened on the cock plug (d) and the latter is carried along by the disc only during the second part of its movement. 2. When using the i. designated connection of a disk fm) with a lever (n) a pump piston (P, Fig. 3 and 12), the seal of which is made adjustable from the outside, that on the leather cuffs (r), rubber inserts (s) and pressure plates (t ) existing piston body pushes a tube (v) , which is slipped over the piston rod (u) and passed through the stuffing box, as soon as a nut rotating on the piston rod acts on the tube.
