Specification of Letters Patent. -Patented J an. 25, 1921. Original application filed July 23, 1919, Serial No. 312,806. Divided and this application filed December a1, 1919. Serial no. 348,669.

To all whom it may concern Be it known that I, JOHN F RICK, a citizen of the United States, residing at Philadelphizncounty of Philadelphia, and State of ennsylvania, have invented a new and use ful Improvement in Liquid-Dispensing Apparatus, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a soda water vending machine, adapted to dis- I pense a measured quantity of flavoring syrup and a measured'quantity of carbonated water, under pressure, into a properly positioned cup.

The mechanism whereby the above objectsare attained is intended more particularly to be coin-controlled, and means whereby the deposit of a coin .renders said mechanism operative are shown, but the mechanism is readily adaptable for use independently of coin control. In an application filed by me July 23,.

1919, Serial No. 312,806, of. which this application is a division, I have fully disclosed the present invention in association with coin-controlled means for-delivering a'cup; the syrup and carbonating water dispensing mechanism being shown as depending for its operation upon the prior successive operations of inserting a coin and operating the cup delivery mechanism to deliver a cup and release the coin, and the coin then so positioning itself as to render thesyrup "and water dispensing mechanism operative. In

Fig. 5is a side view of part ofothe mecha-;

nism immediately controlled by a. coin.

Fig. 6 is a plan view of the coin discharge tank is located an upright cylinder h inclos ing a tight fitting plunger 11 carried by a screw j threaded in the cylinder head and retained. in any desired position by means of a. lock nut k. I

Apipe Z connects one of the horizontal cylinders c with a passage 1 in the upper part of a valve casing m. A pipe n leading from the lower part of the valve casing has a Y branch leading to the bottom of cylinder h, the main line extending upward and out of the tank I) and terminating in a valve 0. A pipe 19 leads from the lower part of the valve casing and terminates in a muffler Q. Small holes r in the side of the pipeallow communication from the pipe to the muflier. A pipe svleads from the muffler, out through the casing (1 and terminates at a nozzle t, which it partly incloses and beneath which is a cup holder 35. The end of the nozzle is protected by a shield at fastened to the casing.

The valve casing m is provided with two valve seats 11 and w and a double-faced valve :12, above the top of which extends a pilot valve 2 adapted to control passage 3 and facilitate the seating of the main valve on seat '2). It will be seen that when the valve is in its lower position its lower face will seat on seat 10, closing communication between cylinder k and nozzle t, while its upper face and the pilot valve will be clear of seat 1) and passage 3 affording communication between cylinders c, the carbonated water supply 6, and cylinder h, and vice versa. A plug is threaded onto the head of valve casing m and may be removed for' cleanin the valve.

A va l ve stem '3, integral with valve m, extends out of the casing through a stuffing box 4 and is fitted on the end with a yoke 5. The yoke carries a spring-pressed tappet having a roller 6 on its end. Valve m is drawn into lower position by means of aspring 7 connected to bracket 8. Beneath -the roller is a horizontal shaft 10 carried by bracket 8 in suitable bearings. Pinned to theshaft is a cam 13 adapted to act on the roller 6 and raise the valve against the action of spring 7, which, when the high, point of the cam passes out of contact with the tappet, returns the valve to its lower position. A second cam 14 is pinned to the shaft and adapted to act on a block 15, provided with a roller 16 and slidable on the bracket ,8, against the action of a spring 17, carried I fastened to a frame 26.

A well 27, provided with apassage 28 flush with the false bottom, is positioned in 'the bottom of the container.

A plunger 29, having a stem 30, is fitted into the well, and a pipe 31 leads from near the bottom of the well through the plunger and through the casing a, terminating in a plain nozzle 12 adjacent to the carbonated water nozzle t, beneath shield u.- A lever 32,'pinn ed to a fulcrum 33, is connected at 'on end to the end of plunger st'em 30 and at the other-end, through a pin and-slot, to a plate 34, suitably secured to the end of shaft 10.

The coin-connected manually operated actnating mechanism for delivering the rup and carbonatedwater comprises a rac bar 66 in engagement with pinion 20. An ori-i' ficed block 67 surrounds the end of the mo bar. and contains a coin slot at an angle therein glust'beyond the end of. the inclosed bar. Tfis block is adapted to be slid along the top of a coin chute 68 by ahand lever 72 pivoted to a suitable support and; having an arm. connected with the block by'slot an pin connection 69.

is entered into its coin slot, however, the

' coin, being larger in diameter than the rackv bar forms a stop. and in the movementof the block the bar isalso. moved,turning 'other coin. acting to'cause the dispensing to ough'the action ofa pawl 21,-

ith a removable cover 24, and a false bottom pinion 10 and operating the dispensing valve.

- Chute '68 has an elongated opening 70 in its top face, underlying block 67 in its move: I

ment by the hand lever. This opening 69 is of such width for most ofits length that the coin falls into the chute.- Opening 70 also serves the purpose of allowing coins smaller than the coin with which the machine is intended to be used to fall directl from the slot in the block and prevent suc take place.

After the block has been made to travel '70 r it willnot permit the passage of the coin in as described, it returns to its initial position providing a slot 66 in the bar adapted to act with a pin 71 in the block to allow free movement of the block when moved without any coin being entered.

- An arm 74 extends from the lever to which I? one end of a spring 75 is fastened, the other end'being fastened to the frame, to return and maintain the lever in its initial position as shown in Fig. 2.

A ratchet 76 is formed on the lever adjacent the pivot having at one end a stop 77 and at the other end a .pawl trip 78. A pawl '79 is pivoted to a suitable support in position to act on the ratchet 76 as the handle descends, until the trip acts to throw it out of engagement, when the handle reaches its lower limit. by a spring 81, engages the short arm of the pawl and holds it in engagement with the ratchet until the pawl is tripped. I The detent then holds the pawl out of its ratchet engaging position until the handle 'is raised and the stop 77 throws the pawl back into en agement with the ratche ivoted to the block engaging arm of lever 72 is a forked'ro'd83 engaging the shaft 10 with its forked end and having a shoulder 84 formed on itsJside. to act as' a stop for shaft 10 through the medium of arm 85 carried by cam 14 and positioned to contact with the arm when the rod 83 is fully ad- .vancedby the lever reaching its lower position. A dash pot 86 is positioned adjacent the lever 72 and connected with the block engaging arm to regulate the speed at'which the lever may "be moved. Ordinarily, block 67 "slides freely on the rack bar without moving it. -When a coin -A coin duct 90, which is adapted to re- A detent pin 80, held in place ceive a coin released from the cup dispensing mechanism (not shown) extends. downward to a point "ust above the coin slot in block 67. A lea spring 91 having a flange 92 at one end is fastened to the corn receptacle 68 and extends upwardly in such a position pushed out of the way'and the coin'may drop into thecoin slot.

To prepare the machine for operation, the valve 9 is'opened, connecting the carbonated water supply with the horizontal tanks 0,

and plunger zfis adjusted in cylinder it so as to adapt the cylinder to receive the desired quantity of carbonated water. The stroke of plunger 29 is adjusted, by adjusting lever 32 on plate 34, to pump the re quired quantity of syrup.

. Cam 13 is positioned to elevate the valve 0 and thus shut off the connection between the carbonated water supply and the measuring cup h. The roller 16 on block 15 is at the low point of cam 14.

The cup is placed in the holder 35 on the outside of the casing, beneath the syrup nozzle and carbonated water nozzle. Assuming that a coin has passed down the com duct 90into the coin slot in block 67,

- and that the lever 72 is then pulled downward, as heretofore explained, this movement of lever 72 rotates shaft 10, through pinion 20, pawl 21 andratchet 22. As shaft 10 turns, lever 32 is actuated and causes plunger 29 to force syrup from well 27, up pipe 31, and into the cup and causes the plunger to again rise, permitting the well to refill.

The rotation of shaft 10 causes cams 13' and 14 to turn. The high point of cam 13 moves away from roller 6, permitting valve 00 to assume its lower position on seat w under the. influence of spring 7, opening communication between the cylinder k, which acts as a measuring cup, and the tanks 0 through passage 3 in the Valve casing and pipe n, causing the measuring cup to fill with carbonated water.

- Cam 14turns on roller 16, forcing block 15 down and tensioning spring 17.

The rack advances turning the shaft 10 and the cams as above described until'the cams assume the position shown in Fig. 7, with cam 13 about to raise roller 6 on the valve tappet and the roller 16 about to leave the high point of cam 14. In the movement of the hand lever, thev forked rod 83 is advanced so that a light continued movement of shaft 10 will cause arm 85 to contact with shoulder 81 and stop further movement.

A slight further movement of the rack caus'esblock 15, under the influence of thetension set up in spring 17, to kick cam 14 around, as roller 16 goes off the high point of the cam, causing cam 13 to raise valve w,

, seating it on seat 1) and causing pilot valve z to close oil passage 3 at the same bination of a measurin time opening communication between the cylinder h and nozzle t, allowing the carbonated water in the cylinder to discharge into the cup and mix with the syrup. \Vhen roller 6 .is on the high-point of cam 13, arm 85 contacts with shoulder -84 and motion handle reaches its initial position. It will be noted that when the lever is moved down it must be moved all the way down andthe coin dropped out before it can be again raised, thus preventing any more than one portion of syrup and water being obtainedwith onecoin.

The mufiler g and arrangement. of thefnoz zle t in pipe 8 prevents the water from splashing and spitting out of the nozzle 1..

When it becomes necessary to wash out the machine, this may be done by attaching a hose to valve 0, opening the valve and turning on a supply of Water. v
