in the majority of automatic coin-freed machines for the dispensing of liquids in pre-determined quantities, and more particularly of petrol for lighters, at present in use the drawing of the liquid is as a rule eected by means of a scooping vessel provided within the container for the liquid. It is clear that with this arrangement special means must be provided within the container for the actuation of the vessel, for which reason, for the purpose of dealing with defects, cleaning, etc., the container requires to be opened, and such opening in time impairs the essential liquidtightness of the container. If the above-mentioned means for the lifting of the scooping vessel be arranged outside the container it becomes necessary to provide a number oi apertures in the container which increase the danger of explosion due to evaporation. In other known automatic coin-freed liquid-dispensing machines employing pumps, valves, or the like it has been altogether impossible hitherto to obtain satisfactory liquid-tightness, and thus to eliminate the danger of fire completely. Moreover all these types of apparatus have the drawback that not only evaporation but also dripping of the petrol occurs. Finally, the cost of manufacturing these types of apparatus is also comparatively high.

In accordance with the invention there is adopted an improved and hitherto not yet employed arrangement by which the above-mentioned drawbacks are obviated, and at the same time a very considerable simplification of the entire device is eiected. The invention is based on the idea of fastening a measuring vessel immovably in the container, and that in such a manner that when the container is tilted a quantity of liquid predetermined by the cubic contents of the measuring vessel flows out automatically. This new principle, that is to say that of tilting the container together with the ladle, vessel, or the like situated therein is employed for the rst time in the automatic coin-freed machine according to the invention. The new automatic coin-freed machine can be simply constructed so that the tilting of the container only becomes possible after the insertion of a coin. Further, the troublesome replenishing of the container with petrol can also be avoided, since the container of the automatic coin-freed machine is simply exchanged for a fresh container, which is not easily possible in the oase of other types of apparatus in which the above-mentioned special means are provided in or in connection with the container.

The invention is illustrated with the aid of a constructicnal example, in the igures of the drawing, in which Fig. 1 shows the interior arrangement or the automatic coin-freed machine, with the outside casing removed, in front elevation, Fig. 2 a side elevation of Fig. l, with the releasing mechanism shownpartly in section, and with the outside casing, Fig. 3 shows the device likewise in side elevation, but during the dispensing of the liquid, and Fig. 4 shows, finally, the arrangement ior the tilting of the container, in plan View.

As is clear from Figs. 1 and 3, the liquid container 2 is mounted on the rear Wall I of the casing of the automatic coin-freed machine, by means of two parallel arms 3, l1. The mounting in these arms is however preferably elected not directly but, in the constructional example described, with the aid of a frame 5 which is rotatably mounted in the arms 3, 4, and which is at right angles to the latter when the apparatus is not in use. The container 2 possesses two or more screw bolts t, 1, on to which screw threaded sleeves 8, which are guided in the upper part of the frame, can be screwed, so that in this manner the container 2 can be fixed in position in the frame 5 or liberated after the slackening of the screw threaded sleeves. The one screw bolt 5 at the same time takes the form of an outlet tube, and serves to establish communication between a discharge nozzle 9 attached to the4 screw threaded sleeve 8 and a tube Iii fixedly mounted within the container. This tube IB leads to the measuring vessel il which is situated at the bottom of the container 2.

As above described, the measuring vessel Il and the outflow pipe Hl are xedly mounted within the container; the pipe l! is disposed obliquely, at an angle to the discharge nozzle 9, so that when the container 2 is tilted from the position shown in Fig. 2 into the position shown in Fig. 3, that is to say on rotation through about 90, the amount of liquid dispensed is precisely equal to the amount present in the vessel Il when the latter is in the normal position (Fig. 1). After the discharge of this predetermined quantity of liquid the container 2 is tilted back again into the normal position shown in Fig. 2.

The actuation of the described device is best eiected in practice by the arrangement that the container is tilted by means of a press-button,

and restored to the normal position by the action of a recoil spring. 'I'heoperation of the pressbutton is rendered possible only after the insertion of a coin; an arrangement of this nature is shown in Figs. 2 and 4.

The press-button i2, which is guided between two arms 2l, 28, and which consists of a button portion proper and of a thrust rail, is provided with a pin i4 which is guided in a radial slot i5 in a coupling disc 2g, and which is adapted to act upon this disc. The disc 29 is firmly connected by means of pegs 3! or the like to an extension 5 on the frame 5. Thus when pressure is exerted upon the thrust rail l2 the container will be tilted through 90 into the position shown in Fig. 3. In order to permit of the carrying out of this movement, however, a spring pawl i8, which is pivoted on a pin I9, must first be brought out of engagement with an arresting notch in the rail. This is eected by the insertion of a coin, by the arrangement that the coin inserted through the passage 2E) drops upon a pin 2l eX- tending laterally from the pawl, or upon a pin 3l attached to the rail 21. If pressure be then applied to the part l2, the pin i E attached to the thrust rail bears against the upper part of the coin, and depresses this latter together with the pawl i8, thereby permitting of the rail being moved further towards the right. The coin then drops of its own accord into the collecting receptacle 22.

During the movement of the press-button l2 towards the right a spring H, which bears against the pin Et, is compressed, so that, after the releasing of the press-button i2, when it is in the position indicated in Fig. 3, the spring restores the same into the initial position, the container, which is positively connected with the rail i2, being likewise returned into its initial position.

t the same time the pawl I 8 moves up again into the arresting position. The thrust rail i2 is guided on the one hand by the connecting pin between the two guiding members 2, 28, and on the other hand by a pin provided in the axis oi rotationof the container.

Any other desired releasing means which are usual in connection with automatic coin-freed machines can naturally be employed in connection with the device Vin accordance with the invention.

In Figs. 2 and 3 the outside casing 23 is also indicated. As will be seen, there are provided in this latter only three apertures, namely an aperture 2li for the insertion of money, an aperture 25 through which the end of the discharge nozzle is brought out, and an aperture for the pressbutton I2. Laterally of the laperture 25 there is preferably provided onv the casing 23 a protective cover 26, so that the lighter to be filled can be held at the right place in advance, before the appearance of the nozzle 9. The measuring vessel l l is preferably made very shallow, so that the automatic coin-freed machine dispenses liquid even when the level of the latter is very low.

An essential advantage of the special arrangement of the discharge nozzle 9 resides in the fact that this latter, except for the short time during which the user of the automatic coin-freed machine draws the petrol, remains constantly concealed in the upwardly pointing position, this arrangement precluding any dripping and ensuring that the nozzle remains inaccessible from the outside.

Any desired known means usual in connection with automatic coin-freed machines can be employed for rendering the apparatus inoperative. In the described automatic coin-freed machine it will be advantageous to provide a ratchet wheel actuated by the press-button l2, which wheel after a certain number of revolutions thrusts a lever under the coin slot 24, and thereby prevents the further insertion of money.

What I claim is:

l. A predetermined measure of delivery mechanism, including a casing, a container mounted for tilting in the casing, means arranged in the container for delivering therefrom a predetermined quantity of fluid on the tilting of the container, means for tilting the container, and a nozzle carried by the container and extended through the casing in the operative delivery position of the container.

2. A predetermined bulk delivery mechanism, including a casing, a container mounted for tilting therein, an outlet nozzle removably connected to the container and extending through the casing wall when the container is tilted, a bulk measuring device arranged in the container and in open communication with the nozzle, and a manually operable element for tilting the container from the exterior of the casing.

3. A construction as defined in claim 2, wherein means are provided for normally locking the operable element against operation.
