To all whom it may concern:
Be it known that I, GOTTLIEB BTDMER, a
citizen of the Republic of Switzerland, res1ding at Zurich, Centralstrasse 53, witzerland, have invented certain new and useful Improvements in Liquid-Dispensing Apparatus; and I do hereby declare the following to be a clear, full, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,
ters or figures of reference marked thereon, which form a part of this specification.
Thisinvention relates to improvements in liquid dispensing apparatus delivering a fixed quantity of a beverage upon the insertion of a coin.
The object of the present invention is to provide an' apparatus of the class referred to which comprises two pivotally mounted levers and a member for controlling the passage of the beverage through a supply pipe for the latter, said levers and mem r being balanced among themselves and being mechanically connected so that an oscillation of one of said levers brought about by an inserted coin effects an opening of Said controlling member and a movement of the second lever from its position of rest into its operative or working position, the latter being returned into its as soon as it falls out of an inclined chute,
efi'ecting thereby a closing of the controlling member of the supply pipe and a returning of the first mentioned pivotally mounted lever into its position of rest. The controlling member comprises a grid valve having slots adapted to be brought into slots provided in a plate fixed to the supply pipe and arranged at rightangles to the axis of the latter.
- Another object of this invention is to provide a liquid dispensing apparatus having a chute'with a guide-channel for the coins and at least two sections oppositelyinclined relatively to a horizontal lane and rovided with an additional guide-channe at the reference being hadto the accompanying drawings, and to'letof Fig. 1;
position of rest by the coin" register with point of transition of the portion of the guide-channel of an upper section into that of a lower section, said additional channel being so arranged that the kinetic energy acquired by the coin while it travels through the upper section of the chute is again consumed in the additional channel of the lower section, so that the length of the whole chute may be reduced for a of the coin through sai chute.
A further object of this invention is to provide a coin-trap for a liquid dispensing apparatus provided with an inspection hole and with means locking an in.- serted coin behind the inspection hole until a new coin has been inserted into the trap.
This invention'will now be more particularly described with reference to the accompanying drawings illustrating a constructional example of the invention.

1ven time of passage arranged a lens in the channel 5 just Referring to the drawings, 1 denotes the slot for the insertion of the coins into the coin-trap. The slot 1 forms the inlet end of a forwardly inclined guide-channel 2 (Fig. 3) provided between an upper rear wall 3 of sheet-iron and a lower forwardly inclined bottom wall 4. The latter has an aperture 6, the width ofwhich is smaller than that of a coin adapted to set the ap paratus into operation, while it is greater than the width'of a coin smaller than one of the kind just referred to. 7
forming a vertical continuation of the channel 2 and confined by a rear wall 7 having a bent upper portion, a front wall 9 providedvwith an opening 9 and two side walls 9 In the bent upper portion of the rear wall. 7 are provided a plurality of slots 8 confined by bars 7 10 denotes a vertical front wall provided with a slot 11 for the ejection of too small coins falling through the apertures 6 on a downward inclined partition wall 12 (Fig. 3). The wall 10 has a further aperture 13 behind which is p 14, said aperture 13 being adapted to be used as an inspection opening; To one of the two sidewalls 9 confining-the ide-channel 5 is fixed a resilient arm 15 ig. 4) provided vwith a pin 16 projecting into the interior of said guidechannel 5 and adapted to arrest a coin 17 behind lens 14. The slots '8 are provided for the purpose of preventing any influencing of the coin 1.7 arrested in the guide-channel 5.by any object introduced in slot 1,, to displace the coin,
such object being guided by the bars 9 through one of the slots 8 and thus prevented from coming into contact with the com 17 locked in the middle portion ofthe channel 5. l
18 denotes adouble armed lever pivotally mounted on a pivot 20 supported in a board 19 of the apparatus. a The end 18 of this lever l8 isadapted to act as a coin-holder and is kept in its position of rest beneath provided the outlet of the guide-channel 5 (Fig. 1). To abolt 21 carried by the other end of said lever 18 is secured an actuator for the dispensing mechanism, such as a rod or a wire 22 connected at its other end to a pin 23 on a one armed lever 24 adapted tooscillate about a pivot 25 mounted in a spectively.
denotes a vertical member provlded with a guide-channel 5 each of thefirst mentioned distances is a multiple of the last mentioned distances re- It will be seen, that the bolt 21 is provided on the left hand side of the pivot 20 and the pin 23 on the right hand side-of the pivot 25.
Between the two pivotally mounted lever arms 18 and 24 is disposed a chute comprising a plurality of sections 27, 28, 29, and 30 respectively. In each of the latter is provided an inclined guide-channel 31 and each of these sections is inclined relatively to a horizontal plane in the opposite direction with regard to theadjacent upper and lower sections. At the points of transition'of the two portions of the "guide-channel 31 provided in two meeting sections of the chute are provided additional guide-channels 32 and 33, 34 (Fig. 7 respectively, each of these addltional channels forming an upward continuation of the portion of the guide-channel31'provided in the lower one lateral walls 37 and 38 (Figs. 8, 9, 10), the
distance between the latter being such that a small'clearance is left between these walls and a coin rolling down the guide-channel 31. The bottom of thelatter is formed by a rib 39 and each side wall 37 and 38 respectively, is also provided with a rib 40;
To the board 19 is fixed a flanged body ,41
of the dispensing mechanism such as acock connectedto a pipe 42 for supplying a'beverage. The body portion 41 is provided at v I its front end with a chamber 43. Within the latter is movably mounted the dispensing element su h as a grid valve 44 into which is screwed the ,pin 23 of the pivotally mounted lever 24. The two levers 18 and-.24 and the grid valve 44 are-balanced" among themselves, by these parts is balanced in every position that said parts may take. The plate 26 already referred to s fixed to the body 41 and constitutes thefront wall of the chamber 43 and is provided'witha pluralityof slot-like apertures 45 cor; ponding to the slots 46 of the-grid valve 44. The chamber 43 admits a vertical movement of the grid valve- 44, so that the slots .46 of the latter may be brought into one row with those of the plate 26, the latter being provided to this end with a slot 47 for the pin 23, so
so thatfthe system constituted that the above mentioned vertical movement of the grid valve 44 is not prevented by said plate 26. 49 denotes an outlet pipe branch for the beverage to be dispensed.
The operation of the hereinbefore described apparatus is as follows:
A coin inserted into the slot 1 passes into the funnel shaped upper portion of the member 7 only when it has the proper size, While a too small coin falls through the aperture 6 upon the inclined partition wall 12 which guides it to the slot 11 provided in the front wall 10, so that it is ejected before it causes an actuation of the apparatus. Each'such actuation of the apparatus is effected only indirectly by a coin of the proper size just inserted, the operation proper being brought by the previously inserted coin held behind the lens 14 by the pin 16 of the resilient member 15 until the just insertedcoin causes it to fall toward the outlet opening of the guide-channel 5. lhe just inserted coin causing the release of the coin 17 is arrested in its turn behind the inspection aperture 13 fitted with the lens 14 by the pin 16. In an apparatus of this kind, any fraudulent tampering is prevented and the insertion of objects without any value may e discovered at once by'looking through the inspection aperture 13 and lens 14.
The coin 17 released by the pin 16 falls upon the coin-holder 18 and causes then, owing to its weight, an oscillation of the pivotally mounted lever 18 in a clockwise direction, it being moved thereby from its position of rest shown in Fig. 1 in full lines into the working'position shown in point and dash lines. The Wire 22. connected to said lever 18 causes in its turn an oscillation of the lever 24 in the opposite sense, so that it is also moved from its position of rest shown in Fig. 1 in full lines into its working position shown in point and dash lines. Fig. 7 shows both levers 18 and 24 in their work ing position. Said movement of the lever 24 into its operative position has the effect to move the pin 23, and consequently also the grid valve 44, upward, so that the slots 46 of the latter taking up normally the position shown in Fig. 14 are brought into register with the slots 45 of the plate 26 (Fig. 15), the liquid to be dispensed being then able'to flow from the supply pipe 42 into the outlet pipe 49. As soon as the lever 18 has been caused to take up the position shown in Fig. 1 in point and dash lines, the coin 17 released by the pin 16 falls into the guide-channel 31 of the chute and rolls at first down hen it reaches the point A (Fig. 7), it possesses a certain kinetic energy, the magnitude of which depends on the weight of the coin and the angle of inclination of the guide-channel 31. In consequence of the acquired kinetic energy, the coin does not the section 27.
fall vertically into the guide-channel 31 of the section 28 arranged below the section 27, but rolls in the direction of the arrow 0 upwardly along the additional guidechannel 32 in which the kineticenergy of the coin is again consumed. At the point B the coin remains a moment stationary, whereupon the action of gravity causes it to roll at first down the additional guide-channel 32 and afterward down the portion of the guide-channel 31 provided in the section 28. A similar interruption of themovement of the coin is also brought about in the additional guide-channels 33 and 34. It will be understood, that owing to the upward and downward rolling movement carried out by the coin in the additional guidechannels of the chute, the time taken up for the passage of the whole chute is increased. In other words, for a given time of passage of the coin through the chute-on which time depends the quantity of the beverage dispensed-a shorter chute taking up less space can be used when such additional guide-channels are provided. As the inclination of the different sections of the chute influences also the time of passage referred to, the length of the chute sections will also control the time of passage of the coin. Owing to the fact that the coin rolling down the chute comes only in contact with the ribs 39 and 40 of the sections 27, 28, 29, and 80 of the chute, any arresting of a wet or adhesive coin in the guide-channel 31 due to the adhesion produced is prevented.
The grid valve 44 remains in the position shown in Fig. 15 until the coin falls through the slot 36 (Fig. 7) of the chute upon the coin holder 27 of the lever 24, which is then caused to oscillate in a clockwise direction, so that it is moved back from the position shown in Fig. 1 in point and dash lines into the position of rest shown in this Fig. 1 in full lines. In consequence of said movement carried out by the arm 24, the grid valve 44 is also moved back into the position shown in Fig. 14. The coin fails then from the coin holder 27 into the coin receptacle 50 (Figs. 1 and 2) of the apparatus and the wire 22 connected to the lovers 18 and 24 In a dispensing apparatus, two pivoted,
