10 all whom it may concern.-

Be it known that I, FRANK W. WATERMAN, a citizen of theUnited States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Coin- Controlled Liquid Vending Apparatus, of which the following-is a specification.

This invention relates to certain new and useful improvements in coin-controlled liquid-vending apparatus,,and has for its principal object to provide a novel construction of parts rendered operable on the insertion of a coin into the machine for permitting a predeter-mined amount of liquid to be discharged from the apparatus.

Otherpbjects of the invention relate to details of construction and to combinations and arrangement of parts cooperating with the aforesaid apparatus, whereby I am enabled to provide a machine of the character indicated which shall be simple and compact in construction, reliable in operation, and one which'may be comparatively economically manufactured.

That which I claim as my invention will be indicated in the claimsfollowing the specification. V

In order that the invention may be clearly understood, I have illustrated the same in the accompanying sheets of drawings, wherein- Figure 1 is a cross-sectional view through the casing viewed from the rear thereof, the parts within the casing being shown in elevation. Fig. 2 is a transverse sectional view,

valve, and Fig. 6 is a'broken plan view showing the connection between the-pull-rod and i the coin-trough.

Similar reference-numerals indicate corresponding parts throughout the several views.

Referring now tov the drawing, the apparatus as illustrated comprises a casing 1, the

lower part of which is of a size adapted to receive a tank 2. For the purpose of permitting the ready entrance and removal of said tank the casing is preferably provided onone side with a hinged door 3. A truck 4 may be provided to facilitate placing the tank within the casing, and a bracket 5 is located at one 5 5 side of the casing to position the tank within the same. Removably connected with the tank 2, as by means of a j am-nut 6, is a pipe 7, provided with a valve 8. The casing 1 is divided by a partition 9. into two compartments, the lower compartment 10 containing the tank referred to above and the upper compartment 11 containing certain parts hereinafter referred to and being adapted also to contain ice.

The pipe 7 leads through the partition 9 into the upper compartment 11, in which compartment it is given the form of a coil 12 and is provided with a continuation 13, connecting with a closed vessel 14, hereinafter referred to as the cooler.

which, together with the coin-controlled apparatus, is located in a housing 17, mounted on the casing 1. The valve 16 is shown in detail in Fig.5, and, as there illustrated, comprises a plug 17 having near two opposite sides parallel passages 18 19, respectively. The casing 20 of the valve is shown to have From the cooler "14 a pipe 15 leads to a two-way valve 16,

four outlets, (indicated, respectively, by 21, 8o

22, 23, and 24,) which are designed to be brought into communication in pairs with the respective passages 18 and 19, as hereinafter described.

and cooler 14 are two measuring vessels 25. and 26, respectively. From the vessel 25 the pipe 27 leads tothe valve 16, and from the valve 26 the pipe 28 leads to said valve. 29

throu h the wal of the housing 17,;where it is bent ownward to provide the faucet 30 for the discharge of the liquid into asuitable receptacle. In the arrangement. shown the pipe 15, leading from the cooler, connects '95 with port 23 of the valve-casing, the pipe 27, leading from the measuring vessel 25, connects with the port 24, the pipe 28,,leading from the measuring vessel 26, connects w1th the port 22, and the pipe 29, leading to the faucet 30, connects with the port 21.

In the operation of the apparatus it is mtended that one of the measuring vessels 25 or26 shall be placed in communication with the faucet 30 to discharge its contents, while the other measuring vessel, which has pre- Mounted in the casing 1 above the coil 12 8 indicates 'a pipe leading from the valve ICC viously been emptied, shall be simultaneously placed in communication with the located between the two brackets is a.

in which the coins inserted in the machine travel, and a coin-chute 47,1eading from the outside of the housing 17, is arranged to deliver coins inserted therein into the slot 46 at the inner end of the coin-trough 42'. Said coin-trough is provided on its inner side. with a lug 48, which is normally engaged by a spring-controlled detent 49, carried by the pull-rod 38, as indicated more clearly in Fig. 3 and the detail view Fig. 6. w a

It will be understood that theengagement of the detent 49 with the lug 48 prevents the pull-rod 38 from being drawn outward to operate the valve. When a coin 50 has been inserted in the machine, itrolls-down to the outer end of the coin-trough, and its weight is sufficient to overbalance said trough and carry its outer end downward, thereby mov ing the lug 48 out of en agement with the detent 49, so. that the pul -rod 38 can be drawn outward by grasping the knob 39. In this operation-the pin 40, engaging in the slot 41, will operate to rotate t e plug of the valve by reason of theengagement-of the pawl 34 with a tooth of the ratchet-wheel 32, which is fixed on the spindle of said lug, and therebybring one or the other of t e passages .18 19 in communication with'the ports of the easing of the valve to pe mit one of the meas uring vessels 25 to d scharge its contents throiigh the faucet 30 and to place the other measuring vessel in communication with the cooler. 14, so that the former may be refilled. Thus in the position of the parts shown by Figs. 1 and 5 the measuring vessel 25 is in communication through the port 19 with the cooler .14, and the measuring vessel 26 is in communication with the faucet through the port 18. In the inward movement of the push-rod 38 this osition of the parts is unchanged, the paw 34 riding over the ratchetwheel until it comes into engagement with a fresh tooth thereon, four te'eth being previded on said ratchet-wheel, so that in each movement of the pull-rod the valve-plug is given a quarter-turn. In the next movement outward of the pull-rod after the insertion of a fresh coin the valve-plug .Will be turned to lacethe passage 18 in communication wit the ipes 27 and 29, so that the measuring vesse .25 will discharge through the faucet 30, and the passage 19 will be .placed in communication with the pipes 15 and 28, so that the measuring vessel 26 may be refilled from the cooler 14. Thus the measuring vessels 25 and 26 will be alterna tely em tied and refilled.

It will eunderstood, of course, that the liquid in the tank 2 is maintained under pressure.

For retracting the pull-rod 38 I provide a relatively long leaf-spring 51; secured at one end to the sideof thehousing 17 and at its other end to the said pull-rod intermediate the ends thereof, as indicated in Fig. 2. In the retractive movement of the pull-rod the detent 4.9 will ride over the lug 48 and resumethe position shown in Figs. 3 and 6.

Pivotally mounted adjacent to the end of the pivoted coin-trough 42 is a gate 52, normall.y held against the discharge end of the coin-trough by the action of a weight 53 on an arm 54, forming a part of said gate. The gate 52 is provided with a hub 55, by means of which it is'pivoted in the outer end of a bracket arm 56, suitably mounted in the housing. Extending upward and rearwardly from the hub is an arm 57. Mounted on the outer end of the pull-rod 38 is a pin 58, which when the pull rod is drawn outward is adapted to ride over the arm 57 and depress the same, and thereby move the gate 5 2 away from the end of the trough 42 and permit the coin 50 to fall. gate is to prevent the coin from falling from p the trough, and thus permitting the latter to rise and bring its lug 58 in front of the detent 49 before the operator has had an opportunity of drawing out the pull-rod.

The purpose of this By the construction described it will be 5 seen that the coin will rest in the coin-trough and hold the lug. 48- below the detent until the person using the machine has had an opportunity ofdrawing out the pull-rod. A suitable receptacle 59 may be .rovided for re- I ceiving the coinsas they fal from the cointrough.

Having thus fully described my invention and the manner of operating the same, I declare that what I claim as new, and desire to secure by Letters Patent, is-
