BEVERAGE- VENDING MACHINE.

To all whom it may concern Be it known that I, DANIEL J (Burmar' nnn, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Beverage-Vending Machines, of which the following is a specification, reference being drawings.

This invention relates to a beverage vending machine, and has for its object the construction of an efiicient and durable machine, which will dispense liquid, such as flavoring sirups, into a receptacle, such as a cup, upon a person placing a coin in the machine and then operating the machine for discharging said liquid.

With this and other objects in view, my invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims. a In the drawings: 7

Figure 1 s a front View, in elevation, of a beverage vending machine constructed in accordance-with the present invention.

Figure 2 is a top, plan view of a complete-vending machine, showing a portion of an adjoining, similar machine, as there may be any number of these machines associated together.

Figure 3 is a vertical, longitudinal, sectional view of the machine.

Figure 4 is a section, taken on line 4'-4, Fig. 2, andlooking in the direction of the arrows.

Figure 5 is a sectional view, taken on line 5-5, Fig. 3, and looking in the direction of the arrows.

Figure 6 is a section taken on line 66, Fig. 3, looking in the direction of the arrows.

Referring to the drawings by numerals, 1 designates the casing which includes the front section 2, the central section 3 and the rear section 4. In the front section 2 is formed an upper coin slot 5, at the bottom of which is a compartment 6. that communicatm with a lower coin slot 7 5 the had therein to the accompanying Specification 01' Letters Patent. Patented Feb, 28, 1922 Application filed November 2, 1920. Serial No. 421,898.

lower coin slot 7 opens into the compart ment or receptacle 8.

Adjacent to the upper coin slot 5 is a' compartment 9, in which is mounted lever 10. Lever 10 is pivotally supported, at 11, wvithin compartment 9. Lever 10 has a coil spring 12 bearing against the same for holding the lever out in the path of movement of a coin 13, Fig. 4. When the coin 13 is placed in slot 5, the weight of the coin is suflicient to overcome the outward pressure of the spring 12, resulting in the lever 10 being pushed inwardly as the coin travels to its lowest position within the upper coin slot and into the compartment 6, Fig. 3. The lower end of lever 10 1s enlarged, at 14, and on one side of this enlarged portion 14 are a pair of pins 15. A cog 16 is rotatably mounted in the compartment 9, and the' teeth of the cog engage the pins 15, of the lever 10; also, said teeth engage cups or receptacles 17 in the compartment 18. One tooth of cog 16 only engages a cup 17, and when the lever 10 is pushed'inwardly by the coin 13, the tooth that is engaging a cup will slightly raise the cup untilthe tooth passesthe edge of the cup and then the cup will dropdown and out of the compartment 18 and the next cup will fall against a tooth of the cog and will not be discharged until another coin has been dropped into the slot 5. The lower pin on the lever 10 operates'or rotates the cog, while the upper pin acts as a stop or brake for limiting rotary movement of the cog each time the coin 13 is dropped in the slot 5.

A primary valve 19 is positioned in the central sect10n'3 of the casing 1, and an auxiliary valve 20 is positioned in the rear section 4. The primary valve 19 is operated by a coin-controlled pusher device," this coin-controlled pusher device comprises a manually-controlledouter section 21 and an inner section 22 (Fig. 3). The outer section 21 includes the push cap 23, pin 24 and spring 25; The inner end of the pin 24 is adapted to bear against the coin 13, when in the compartment 6 at the lower end of the upper slot 5, and upon the push cap 23 being pressed inwardly by the operator, the cap 26 of the inner section 22 will be pushed inwardly; the shaft or pin 27 is attached at one end of the cap 26 and itsother end is attached to the prlmary valve 19. A spring 28' is mounted upon pin '27 for normally holding the valve 19 in a closed position upon its valve seat 29, and said spring 28 also retains the outer end of the cap 26 in position to be engaged by a com 13 when one is dropped into the compartment 6. If no coin is in thecompartment 6, and. the push cap 23 is pressed inwardly, the inner end of pin 24 will ride into the socket 30, which socket extendsla considerable d stance into pin 27, as shown by dotted lines, Fig. 3.

The auxiliary valve .20 is operated by liquid pressure; a shaft or in 31 is fastened to valve 20, and" on t e inner end of pin 31 is a plunger head or cap 32 against which the liquid engages, and when pressure is sufficient the ca 32 w ll be forced toward the outer en of cas1ng 1, moving the valve 20 outwardly from its seat, permitting water or carbonated water to enter the rear end 33 of the casing 1, passing from the section 4 into by-pass pipe 34 and discharged into the nozzle 35.

A sirup receptacle 36, preferably formed of transparent material, such as glass, is mounted upon the casing 1 and communicates with the interior thereof (Fi 3). A valved device 37 is mounted upon t e receptacle 36 for permitting air to pass from within the receptacle as sirup or liquid fills the same. Sirup is supplied to the receptacle 1 by supply pipe 38.

It is-to be understood that spring 28, as well as spring 38 normally retain the valves 19 and 20, respectively. in a closed or seated position for preventing liquid to pass through the casing until a coin has been dropped into the machine, whereupon the manually-operated pusher device can be forced inward to move the primary valve 19 to an open position, permitting the liquid or sirup in the receptacle 36 to be discharged by the valve 19 and through the nozzle 35 into a cup or rece tacle placed below the nozzle, as shown in ig. 5. The supply pipe 38 normally keeps the receptacle 36 filled. The inward movement of the valve 19, from its seated position, will result in it pushing against the plunger head or cap 32 forcing it inwardly, causing the auxiliary valve 20 to move to an open position, permitting water or carbonated water to pass by the auxiliary valve into pipe 34-. and be discharged at the same time the sirup is discharged, through the nozzle 35, into the cup 17. On the extreme inner end of the shaft or pin 27, is a closure device 39 that closes the inner end of the supply pipe 38, (see dotted lines, Fig. 3) opening into the section 3, when the primary valve 19 has moved to its innermost position, thereby preventing momentarily any more sirup from entering the casing 1 or the receptacle 36, until the 55 liquid in receptacle 36 has been discharged and the primary valve 19 has moved to its seated position, F'i 3.

If it is desired, the auxiliary valve device, constituted by the valve 20 pin 31 and cap 32, may be entirely remove and by closing valve 40, of the supply pipe 38, a mixed beverage suppl pipe may be attached, at 33, an upon t e primary valve device being actuated, to move the valve 19 to an open position, the mixed beverage will pass from the inner end of the casing 1, through the nozzle 35 into receptacle or cup 17.

It is to be understood that a number of my machinesmay be associated together, as indicated in Fig.2; ata soda fountain, these machines may ''be arranged in series, with a common water or carbonated water supply pipe connected to all of the casing, at 33. A different sirup is discharged into each receptacle 36, through supply pipe 38.

Of course, it will be understood that when valve 40 is closed, valve 40 on pipe 34 will have to be closed too, so that the mixed liquids being supplied at 33 will have to pass directly through the casing to the nozzle 35. Ordinarily both valves 40 and 40 will be left open so as to allow free passage of liquid during the Operation of the machine, including the primary and auxiliary valve devices shown clearly in Fi 3.

While I have described the pre erred embodiment of my invention, and have illustrated the sa'me'in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a machine of the class described, the combination of a casing provided with a nozzle, a manually-operated coin-controlled valve device in said-casing, a liquid-operated auxiliary valve device in said casing, means formed upon the casing for permitting liquid to pass by said valve devices and be discharged through the nozzle when the valve devices are operated, and a container mounted upon said casing and adapted to be emptied when the valve devices are operated,

2. In a machine of the class described, the combination with a casing provided with a dlscharge nozzle, a by-pass pipe mounted upon the casing and having one end opening into the nozzle, a primary valve means in the casing for partly preventingliquid from passing into the nozzle, an auxiliary valve device in the casing fornormally preventing liquid from passing throu h the b ass p1pe, said auxiliary valve evice inc 11d a pin provided at its outer end with a valve and at its inner end with a plunger head or cap, and a spring on said pm for normally holding the valve in a seated position within the casing, whereby when said primary valve means is operated liquid will be pressed against the plunger head or cap, causing the pin and valve thereon to move for permitting liquid to and be di In testi signature.
