s rncrrrcii'rion arming pm or Letters Patent No. 653,488, data Jury 10, 1 900. Application filed February 19} 1900. Serial No. 5,868. (No model.)

T0 all whom, it may concern:

Be it known that I, RoBERrP. SOHILLING, a citizen of the United States,residing at Berkley, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Coin-Controlled Vending- Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to coin controlled vending-machines, and has particular refer= ence to a device of this character designed and adapted to dispense liquids.

The inventionconsists in the peculiar construction of the vending-machine and in the novel combination and arrangement of its various parts, as will be more fully hereinafter described and shown. In the drawings, Figure 1 is a vertical central section, partly in elevation, through the machine detached from the casing. Fig. 2 is a side elevation, partly in section,of the mechanism, showing fragments of the casing at tached thereto. Fig. 3 isa cross-section taken on line a; as, Fig. 2. Fig. at is a side elevation of the machine as in use. Fig. 5 is a vertical central section through the measuring-cup. Fig. 6 is a perspective View of the coin-actuating mechanism and the operating device therefor; and Fig. 7 is a section on line y y, Fig. 3.

A is an inclosing casing having an entering-slot B formed therein, as shown. I a

A designates a receptacle within the casing into which the liquid is stored, the receptacle being in the form of a measuring-cup provided with suitable valve-controlled inlet and outlet ports hereinafter described.

B designates the casing of the outlet-valve connected to the threaded nipple Gupon the measuring-cup, and D represents the inlet-' valve casing, which is connected to and communicates with the casing B through a suitable connecting'pipe E.

F is a discharging device in the form of a spout, consisting of a tubular member G, fixed to the lower end of the valve-casing 13,1 anda movable'telescoping member H, mount ed upon the stationary member for vertical reciprocation. The members are normally separated by means of a coil-spring I, which abuts at its upper end against a flanged ring J, secured to the stationary member, and at its lower end against the upper portion of the nozzle K.

L represents the outlet-valve, which bears normally against its seat M, and O is a valvestem extending upwardly Within the casing.

P represents a coil-spring encircling the valve-stem adapted to bear against a stop 0. upon the latter and the valve-casing and acting to normally hold the valve to its seat.

Extending within the stationary member of the discharge-spout is the stem I), carried by the valve just described.

0 is a slot formed in the side of the upper tube or spout member, through which an arm d of a bell-crank levereextends. This lever is pivoted at the junction of its arm to a bracket-arm a, secured to the spout. The

inwardly-extending lever-arm is connected in constructed as to deliver a coin upon said shelf between the arm f of the bell-crank le- 7 ver and the member G of the discharge-spout.

Within the valve-casing D is arranged the ivalve U, provided with a stem V, connected through a yielding link g and a spring h to an arm 2', extending outwardly from the angle-plate S. The yielding link comprises, es-

. It acts normally to hold the valve U away from its seat 0, so as to allow the inletto the measuring-cup to be normally open. The connection between this valve and the operating device of the mechanism, which in this case is preferably the reciprocating member of the d ischarge-spout,is the bell-crank lever to, pivoted upon the bracket-arm a. One arm pof this lever projects past the yielding link and beneath the pin q, secured to the socket, while the other armr extends in a parallel direction with the discharge-spout and is held constantly in contact with said spout through the agency of the spring h.

After the coin has been inserted within the machine and the device operated in the manner that will be hereinafter set forth the coin is automatically deposited into a box or coinchamber X. The automatic means which I employ for this purpose is of the following construction:

Y represents a roll journaled at its ends in the angle-plate S and a bracket-arm Z.

r is a pin fixed upon the upperpart of the roll adapted to engage the member R of the shelf, so that upon the movement of the roll in either direction the shelf will be actuated.

s designates a spring-actuated pin arranged within a recess t in the roll, the spring being fixed within said recess to prevent the pin from being moved entirely out of the latter. The pin last described extends normally within the path of the tapered head 0 upon the member H of the discharge-spout.

The liquid that is to be dispensed is supplied to the apparatus through the valve-controlled inlet-port, before referred to, in any suitable manner, necessarily under pressure when the source of supply is located beneath the machine. The liquid is free to pass normally into the measuring-cup, and the air within the cup is forced out through the valvecontrolled venttube a The measuringreceptacle consists, essentially, of the cup proper, 12 in which is arranged a pistonhead 0.

(1 design ates a hollow piston-stem, which is provided with a head 6 swiveled within the piston, and extends outwardly from the cup through a stuffing-box 7L2 and to and through a threaded tubular bearing f supported upon the frame g At the upper end the pistonstem is provided with an operating handle or knob i and is also threaded, as at j whereby the piston may be raised or lowered to determine the quantity of liquid that is to be dispensed.

7c designates a valve for the hollow stem (1 Z is a tubular stem for this valve, extending within the hollow stem referred to, and is provided at the end thereof with a head m 0 designates a spring interposed between this head and a shoulderp upon the stem (1*, the spring acting to maintain the valve normally against its seat.

(1 represents a threaded rod the upper end of which has a threaded engagement within the valve 75 and its stem, while the lower end is connected to the stem of the valve L, the latter connection being preferably a lost-motion connection of any well-known and suitable type, so as to insure the proper closing of both valves. The thread upon the rod g is of the same pitch as the thread upon the hollow piston-stem, and the valve is connected to the head 6 by means of a suitable bolt 6. This bolt permits vertical movement, but prevents rotary movement, of the valve 76 relatively to the head 6".

It will be seen from the above construction that the capacity of the measuring-cup may be varied at will by simply turning the operating-handle and that the shifting of the piston to effect this variation will not in any way interfere with the action of the inlet-valves.

The parts of the mechanism having been thus described, the operation of the machine is as follows: A coin isinscrted within the entering-slot in the casing and is delivered by the chute upon the shelf in such manner as to form a coupling between the leverfand the operating device. The operator then moves the section H upwardly until the tapering or inclined head thereon engages the lever-arm 7', which actuates the valve U, closing the inletport to the receptacle. Upon further movement of the spout-section the head thereon forces in the pin .9 within the roller until the head passes by the latter, when the pin is released and engages beneath the head. Still further movement upward of the spout-section causes the inclined head to bear against the coin, which forces out the lever-arm f, opening the outlet-valve and the valve 70 Air is thus enabled to enter through the pistonstem into the measuring-cup,and the fluid that is to be dispensed passes down through the discharge-spout and into the glass or similar receptacle which is held beneath the same. After the contents of the receptacle have been emptied the glass is withdrawn from beneath the spout and the latter is returned, by means of the coil-spring, to its normal position. The shoulder a upon the head upon the downward movement of the spout-section engages the pin .9, which revolves the roller and forces the shelf from beneath the coin, allowing the latter to drop into the chamber or money-box before referred to. The shelf is automatically returned to its normal position by means of a spring 11 which is connected to the roller and the angle-plate. The discharge of the coin from the coin-pocket described allows the outlet-valve of the apparatus to automatically close, and the passage of the head out of engagement with the lever-arm 7' permits the inlet-valve to be automatically opened. The

IIO

fluid from the source of supply then enters the measuring-cup through the inlet-port, and the air in said cup is forced out through the air-vent a controlled by a float-valve a In order that the operating device of the mechanismviz., the reciprocative spoutmay be readily actuated, I have provided a lip c for the nozzle portion K, against which the glass is adapted to bear when raising the spout. Also I have provided a strainer (l for the movable spout-section in order that the liquid that is dispensed may be free from impurities. The strainer referred to is in the form of a tubular netting closed at one end,

which is adapted to be inserted within the movable section and which is provided wit-h a head a, which has a threaded engagement with the interior portion of the nozzle K.
