DEVICE FOR RETAILING AND MEASURING LIQUIDS.

Application filed March The present invention relates to a device for retailing and measuring liquids which are drawn off from a supply container into a measuring vessel.

The novel feature of the device consists in a hand lever arranged so as to control not only the inlet and the dehvery valve and a venting valve of the measuring vessel but also a valve. by means of which may be seen in a gauge glass the complete filling of the measuring vessel as well as the remaining level in the container.

The annexed drawing represents as an example one working form of the novel device.

Therein are- Figs. 1 and 3 two side elevations and Fig. 2 a plan view while Figures 4, 5 and 6 are views of the device 1th reference t diagrammatical in different posltlons. o the drawing an open measuring vessel 1 preferably of glass is provided with a delivery 2 opening on a piston valve orifice controlled by the inside of the vessel and is tightly shut by means of a cover 5 a packing pressed between said tegral with the vessel by means of screws,

clamp and a collar The discharge neck ring 4 being kept comcover and a rim 1n- 3 of angular cross-section.

7 of a supply container not shown in is bolted to a block 36 which is connected to said cover 5 by means of the flanges 35 and which contains the inlet canal 9 with the inlet piston valve 8 of the measuring vessel. This valve opens upwards and is kept open by a tension spring 10 attached to a sleeve 12 lodged within the valve box and to a sleeve valve stem and guid Valve 2 however the cover 11 of 13 fast to the ed within the first sleeve.

having a valve stem extended from the bottom of the vessel to the outside of its cover springs 16 attached to kept closed by two the cover and to a cross pin 15 stuck through the end 1 1 of said stem. A hand lever supported in standards 17 is its pivot by means end of a two arme other end carries a fork 22 rigidly fast to secured to a shaft 19 connected near of a link 20 to the one d lever 21 which at its pin 23 engaged into a the end 14 of valve stem 2. Theconnection between hand lever 18 and link 20 is effected. by a pin 24 fast to said lever and engaged in a slot 25 of said link so that lever 21 will only be moved by said lever and valve 2 be opened when this lever is in its lowe shown in Flg. 6. I

st depressed position as n this position only this 11. 1928, Serial No. 94.059. and in Germany April 3, 1925.

discharge valve 2 will be opened by fork 22. Mounted loosely on shaft 19 is also an arm 27 which is kept in position by a bent finger 28 secured rigidly fast to the lever 18 while a torsional spring 26 sleeved on shaft 19 and fastened at one end to the same tries to swing said arm 27 downwards. In the uplifted position of lever 18 this arm is out of contact with the top end of valve stem 8 but will press this stem downward so as to close said valve 8 only when the lever 18 is depressed into an intermediate position as shown in Fig. 5 and an extreme position as in Fig. 6.

Besides the inlet canal 9 there are also pro vided in the cover 5 canals 29 and 30. Canal 29 intended as venting means is controlled by a cock and likewise canal 30 which carries an open gauge glass 31 extended to the whole height of the supply tank. The two cocks having their passage ways arranged perpendicularly one to the other are operated by two parallel arms coupled by a link 32 and an. arm 33 connects one end of this link to an arm 3 1 secured rigidly fast to the shaft 19. The relative position of this arm and the arms of the cooks is chosen such,- that on the uplifted position of lever 18 (Fig. 4) that is while the inlet valve is open, cock 29 will be closed and cook 80 open. In the intermediate position of lever 18 however, when both valves 8 and 2 are shut and the measuring vessel is filled, said cocks will be closed (Fig. 5) and in the most depressed position of lever 18 (Fig. 6) when the discharge valve 2 is open the venting cook 29 will be open again, while cook 30 remains shut.

The working of this retailing device is as follows For filling the measuring vessel 1 the hand lever 18 is moved from the extreme depressed position as shown in 6 into the extreme uplifted position as shown in Fig. 4c. Thereby the discharge valve 2 will be closed but the inlet valve 8 will be opened only when the lever 18 has reached its extreme uplifted position. WVhile the filling of vessel goes on the air escapes through the gauge cook 30 and the gauge glass 31 and when the filling is at an end the liquid will rise within the glass up to the remaining level in the supply container. The vessel 1 being filled and lever 18 in its extreme uplifted position the discharge of the liquid is effected by pressing lever 18 down at first into the intermediate position (Fig. 5) where all valves and cooks are shut and then into the lowest position (Fig. 6) Where valve 2 and cock 29 are open.

The position of Fig. 4 is to he considered as the position of rest.

What I claim is:

In a retailing and measuring device for liquids Where the liquid is drawn from a supply container into a measuring vessel and in combination a cover secured tightly to the vessel, a connecting neck between the container and cover a piston valve arranged inside 01 said neck for controlling the filling of the vessel and having its stein extended to the outside of said neck, a tension spring supporting: the piston of said valve in an open uplifted position, a discharge valve in the bottom of the vessel and having its stem extended to the outside of the cover, tension springs fastened to the end of the valve stem of the discharge valve and to the top side of the cover so as to normally maintain the said valve in closed position, a venting canal and a canal joined to a gauge glass both provided in said cover, cocks arranged so as to control said canals, a shaft mounted in standards on said cover, a hand lever rigidly fast to said shaft and link and lever connections between the shaft and the valves adapted to operate the inlet and outlet valves and to move said cocks so as to secure the mutual perpendicular position of the passage ways 01 the same.

In testimony whereof I atfix my signature.

ROBERT SUTTER.
