SPECIFICATION formingpart of Letters Patent No. 763,645, dated June 28, 1904.

Application filed December '7, 1903. Serial No. 184,171. (No model.)

T all whom, it may concern.-

Be it known that I, MARTYN ARNoLDUs VAN DERVVIELEN, director, a citizen of the N etherlands, residing at Rotterdam, in the Netherlands, have invented new and useful Improvements in Coin-Controlled Liquid-Vending Apparatus, of which the following is a specification.

My invention relates to a coin-controlled apparatus for delivering certain quantities of liquidforinstance, water-in proportion to the one or several coins inserted. The new apparatus is preferably arranged in connection with a liquid-meter, and essentially comprises a valve-box with two valves, (the one for receiving liquid from the liquid-meter and the other for discharging the liquid measured,) two levers for actuating the two valves, a locking-wheel, gearing connecting the liquid-meter with the locking-wheel for driving the latter, an arm for disengaging the locking-wheel from the gearing, a detent for looking or releasing the locking-wheel, and a hand-slide arranged to move, by means of the coin inserted, the two valve-actuating levers severally and the disengaging locking-wheel through a I corresponding angle, whereupon this wheel is again engaged. The whole construction of the new liquid vending apparatus will be hereinafter more particularly described, with reference to the accompanying drawings, in which Figure 1 is an elevation of the apparatus in a form of construction, the normal position of the hand-slide being indicated by dotted lines. Fig. 2 is a plan of the same. Fig. 3 is a vertical longitudinal section through the apparatus without liquid-meter and registering device on the line A A in Fig. 2, the handslide occupying its normal position. Fig. 4 is a horizontal section through the same on the line B B in Fig. 1. Fig. 5 is a vertical crosssection through the valve-box on the line C C in Fig. 4. Fig. 6 is a vertical section similar to Fig. 3 in which the hand-slide has been pushed inward a little. Fig. 7 is a horizontal section through the valve-box, the two valves being closed by the parts shown at Fig. 6. Fig. 8 is a vertical section similar to Fig. 3 in which the hand-slide is pushed inward through a farther distance. Fig. 9 is asimilar vertical section in which the hand-slide is farther pushed inward and so much that the locking-wheel is disengaged from its gearing. Fig. 10 is a horizontal section similar to Fig. 4 in which the parts occupy the same positions as in Fig. 9. Fig. 11 is a vertical section similar to Fig. 3 in whichthe hand-slide occupies its extreme positions when pushed inward; and Fig. 12 is a horizontal section similar to Fig. 4, showing the relative positions of the parts for the same extreme position of the hand-slide as before.

Similar numerals indicate similar parts throughout the several views.

The coin-controlled apparatus is mounted on the base 1, of sheet metal, and is in connection with a known liquid-meter (or water-meter) 2. The construction of the liquid-meter 2 is immaterial, it being only essential that the liquid-meter 2 be provided with a projecting shaft 14, (see Fig. 3,) which is driven in any known manner by the liquid passing through the meter while being measured. The liquid is assumed to enter themeter 2 through the inlet 42 and to leave the same through the outlet 43. To the casing of the liquid-meter 2 a conveniently-shaped frame 4 is secured, which may be supported by a leg 3 shown. The driving-shaft 14 is tightened by a suitable stufiing-box 44 and is arranged to drive a vertical shaft 16 within the frame 4 by means of the bevel- wheels 15 and 17. The shaft 16 actuates a registering device 18 of any known construction, so that the quantity of the liquid passed through the meter 2 will be shown on the dial of the said. device. On the lower end of the shaft 16 a pin- 7 ion 19 is fastened, which engages a gear-wheel 20, secured on a vertical shaft 45. The latter is mounted to turn in a special frame 46, fastened on the bottom part of the frame 4. Secured to the shaft is a second gear-wheel 21, which can engage with a gear-wheel 22, secured on a vertical shaft 23. On the frame 46 is fastened a guide 26 for the hand-slide 58 27. The guide 26 has a vertical front wall to which the vertical coin-channel 28 is attached.

The whole apparatus may be assumed to be so inclosed in a suitable casing (not shown) that the upper end of the coin-channel 28 terminates in the top face of the casing andthat the knob 48 of the hand-slide 58 27 always remains without the casing, while the inlet 42 of the liquid-meter 2 and the outlet 53 (which will be referred to later on) just project through suitable holes in the casing.

The guide 26 is provided with a boss 49, in which the shaft 23 turns. On this shaft 23 a locking-wheel 24 is fastened, which will be described later on. On the upper end of the shaft 23, between the top part of the frame 4 and a bearing 47, secured thereto, a gearwheel 37 is arranged so that it is prevented from moving vertically, While the shaft 23 can be shifted longitudinally. It will be evident that on raising the shaft 23 in a manner to be described hereinafter the gear-wheel 22 will be disengaged from the gear-wheel 21, (see Fig. 9,) so that the locking-wheel 24 can be turned as desired.

A valve-box 5, Fig. 5, is secured on the top plate of the frame 46 and provided with two horizontal externally-threaded tubes 6 and 7, (see Fig. 4,) which thus can be adjusted longitudinally and secured by means of counternuts 50 50. The one tube, 6, is connected with the outlet 43 of the liquid-meter 2 by means of a tube 51 and a coupling 52. The other tube, 7, is cast in one piece with a nut 53, into which a discharging tube or piece (not shown) is to be screwed.

The two tubes 6 and 7 are placed in two different vertical planes parallel to each other, and their internal ends serve as seats for the two valves 8 and 9. A horizontal shaft 10 at right angles to the hand-slide 58 27 and the two tubes 6 and 7 is mounted to turn in the valvebox 5 and the front wall of the guide 26. (See Fig. 4.) On this shaft 10 an arm 54 is fastened, to which the one valve,8, is so hinged that it can readily apply itself to its seat on the shaft 10. On the front end of the shaft 10 a lever 30 of the shape shown at Fig. 3 is fastened, by which the valve 8 is controlled. A sleeve 13 loosely surrounds the shaft 10 and passes through the cover of the valve-box 5, in which it is tightened by means of a stuffing-box 11. The external end of the sleeve 13 is made thick and equally tightened by another stufiing-box, 55. On the sleeve 13 within the valve-box 5 an arm 56 is fastened, to which the other valve, 9, is hinged, as shown at Fig. 5, so that it applies itself to its seat on the sleeve 13. On the external thick end of the sleeve 13 is fastened a bent lever 31 of the shape best shown at Fig. 11 for controlling the valve 9. On the hub of. this lever 31 a detent 32 (see Fig. 11) is fastened, which is arranged for engaging in the deep cut 25 of the locking-wheel 24, and thereby locking the latter. The detent 32 is provided on the lower surface of its free end with a ball 36, which is so held that it can freely roll on the top surface of the locking-wheel 24 during the rotation of the latter, whereby the friction is reduced. On thedetent 32 a bent arm 33 (see Fig. 9) is fastened, which is adapted to raise the locking-wheel 24, and thereby disengage it fromthe gearing. A spiral spring 35 is attached at the one end to the top part of the frame 4 and at the other end to the detent 32. This spring serves for pressing the detent 32 on the locking-wheel 24, and on the former engaging in the cut 25 the spring 35 also serves for pressing the valve 9 against its seat, and thus stopping the delivery of the liquid.

A fork-shaped slide 58 is mounted to move longitudinally in the guide 26 and is rigidly connected with a rod 27 to form a hand-slide which can be pushed inward and drawn out by means of the knob 48. This slide 58 is so much out out as to leave in its extreme position (shown at Fig. 11) suflicient space for the two levers 30 and 31. Near the left end the slide 58 is provided in its two arms with two vertical cuts 59 59, in which the coin 29, Figs. 6 and 8, inserted is allowed to move vertically. When drawn out, the hand-slide occupies such an extreme position that its cuts 59 59 register with the opening in the coinchannel 28, (see Fig. 4,) so that the coin 29 inserted falls into these cuts 59 and is thereby held. The bottom of the guide 26 is provided with three slots 60, 61, and 34. The one slot, 60, is so shaped as to allow the coin 29 to assume its lowest position (shown at Fig. 3) and to permit it to again rise on the hand-slide being pushed inward from right to left, Fig. 6. The second slot, 61, is necessary for leaving space to the two levers 30 and 31. The third slot, 34, registers with the cuts 59 when the hand-slide occupies its extreme position. (Shown at Fig. 11.) The slot 34 leads to a channel 62, Fig. 1, through which the coin 29 can drop and fall into a convenient receptacle, (not shown,) guided by the two guides 63 63 on the base 1.

The locking-wheel 24 has several (here six) teeth, against either of which the coin inserted is adapted to strike, so as to turn the lookingwheel through a corresponding angle. (See Fig. 10.) As the locking-wheel 24 is prevented from turning when the detent 37 engages in its out 25, it will be evident that five coins at the utmost can be inserted one after the other and pushed against the lockingwheel 24 to turn it in the direction of the arrow. To prevent the locking-wheel 24 from turning further, the gear-wheel 37 engages in a rack 38, provided with a pointer 39, which latter projects through a slot of the scale 40. It is evident that on the pointer 39 pointing at 5 of the scale 40 it will be stopped by the end of the slot and cannot move farther. The scale 40 may also be made visible through a convenient opening or a glass plate in the casing inclosing the apparatus.

In order to enable the gear-wheel 22 to at locking-wheel. and thereby brings the latter into the correct position for dropping.

The apparatus described so far is operated as follows; Normally thehand-slide 58 27 oocupies its extreme position when drawn out and the detent 32 engages in the cut of the locking-wheel24,-so that the discharging- Valve 9 is pressed on its seat by the spiral spring 35,- and thereby stops the delivery. (See Figs. 3 to 5.) On inserting a coin 29 in the channel 28-it will fall into the cuts 59 59 of the slide 58 and occupy theposition shown at Fig.3. On pushing inward the hand-slide by means of the .knob 48 the coin 29 will soon the lever 30 and raise the latter.

plied toits. seat. strikes against the second lever 31 and raises it, so as not only to detach thedischargingvalve 9 from its seat, but also to first disengage the detent 32 from the locking-wheel 24 (see Fig. 8) and then to raise the latter by means of the arm 33 out of engagement with the gearing. (See Fig. 9.) Now the coin 29 strikes against the respective tooth of the locking-wheel 24 and turns the latter in the direction of the arrow in Fig. 10 through the distance of a pitch, when the slide 58 will attain its other extreme position and the coin 29 drops through the slot 34 and the channel 62 into the receptacle. Then the two levers 30 and 31 are released, so taat the one, 30, returns into its initial position and opens the receiving-valve 8, while the other lever, 31, is checked by the locking-wheel 24 dropping into engagement with the gearing, so that the discharging-valve 9 remains in its opened state. Under the pressure of the liquid the meter 2 is now started, so that liquid passes therefrom through the tubes 51 and 6, the valve-box 5, and the tube 7 to the outlet. At the same time the driving-shaft 14 is rotated to turn back'the locking-wheel 24 in the 'direction of the arrow in Fig. 12 and also to actuate the counter 18. 0f course during this time one or several further coins may be inserted to turn the locking-wheel 24 forward if the quantity of liquid vended is to be increased. In case five coins in all are inserted the locking-wheel 24 will be so turned that its out 25 is brought into the position indicated by the dotted lines in Fig. 12. The liquid will continue flowing out until the lockingwheel 24 returns into its initial position, when (See Fig. 6.)"- In consequence of this-motion of the lever 30 with the shaft 10 the receiving-valve 8 is ap- 5 At this moment the coin 29 the detent 32, under the action of the spiral spring 35, will fall into the cut'25 and stop the wheel-24. Thereby also the dischargingvalve 9 is again closed.

It is evident that the quantity of the liquid delivered depends upon the number of coins inserted, as the locking-wheel 24 will take the more time to return into its initial position the more coins are introduced.

The coin-controlled liquid-vending apparatus can be varied in many respects without deviating from the spirit'of my invention.
