MEASURlNG-FAUCET.

T'JPECIPICATION forming part of Letters Patent No. 325.317, dated September 1, 1885.

(No model.)

To an whom it may concern.-

Be it known that 1, JOHN E. CAREY, a citizen of the United States, residing at Gladbrook, in the county of Tama and State of Iowa, have invented certain new and useful Improvements in Faucets, of which the following is a specification.

The object of my invention is to produce a faucet for liquidssold in given quantities, especiall y beverages, so arranged as to automatically receive the coin in payment for the draft anddischarge a certain quantity of liquor on payment of the proper price, thereby dispensing with the services of any person besides the purchaser in the operation.

, The invention consists in a novel construction and arrangement of parts to this end, as will be hereinafter more fully set forth.

In the accompanying drawings, Figure 1 represents a plan view of the faucet; Fig. 2, a longitudinal section of the same; Fig. 3, a front end view, and Fig. 4 a rear end view, of the same.

Similar letters of reference indicate corresponding parts.

The spout or faucet proper, A, is a com para tively long tube having a smooth uniform bore nearly or quite its entire length. In the tapered and threaded portion which enters the cask the bore may be reduced.

About midway on the under side is a spout or orifice, B, and a short distance behind it may be a secondary one, B. The former is for the use of the purchaser, the latter for the proprietor, as will be hereinafter explained.

In a plane recess on the upper side, A, is fitted a slide, 1, operated longitudinally by the lever J. The slide covers and uncovers a transverse slot, 0, of exactly the right dimensions to admit a coin of the denomination required. The slide also covers a longitudinal slot in the faucet through which a stud, 6, passes and connects with a plunger, H, operating in an interior cylinder, G. This cylinder is nearly or quite the diameter of the desired coin and forms a part of the piston which opens and closes the faucet. Near the front end this cylinder is separated into two parts connected at each side by longitudinal ribs a n, leaving just enough space between the two parts of the cylinder to receive the coinm. At the end of the longer portion of the cylinder is fitted a diaphragm, e, having a central orifice to allow the passage of astrong, sharp ncedle, d, projecting from the plunger H. The front end of the cylinder moves in a crescent'shaped plug, K, having a slot, f, near the front end, through which the coin drops when the cylinder reaches the proper point, passing thence into the caslrbox E, secured to the under side of the faucet. A. flange, E, extends upward from the front side of the cash receptacle and closes this end of the faucet. For convenience it may be hinged to the cashbox near the bottom of the faucet, and for security should be provided with a lock. The cash-box may havea door with a suitable lock, or may be supplied with an inclined pipe terminating in the till.

To the back end of the cylinder is secured a piston-head, F, fitted hermetically to the interior of the faucet by rubber or other suitable packing, o. A threaded central rod, 0, admits of the two parts of the piston-head being screwed together upon the packing to tighten it, but also provides for regulating the distance between the two heads F and F which measures the size of the draft. A lateral passage, D, allows the liquid to flow around the rear head, F, when thrust back to its normal position, as in Fig. 2.

The operation of the invention will now be easily understood. The space between the piston-heads F F is already filled with liquid. The purchaser inserts a dime or other coin of the proper denomination in the slot 0, and it then forms a solid head for the cylinder G. As the cam-lever J is operated, the plunger H is moved forward, and the point of the needle (1, pressing against the center of the coin held between the two parts of the cylinder, forces the entire piston forward until the front head, F, passes the hole in spout B, allowing the liquid to escape, and the coin reaches the slot f, through which it drops as soon as the pressure is released. It will be seen that the device can only be operated when supplied with a coin, and that of the proper denomination. \Vhen empty, any movement of the lever simply slides the plunger back and forth in the cylinder. If too small a coin be inserted, the needle pushes it out of the cylinder without moving the piston. A larger coin, but of a smaller denomination, cannot be inserted at all. The

' ing the outside diameter and forcing it out of the cylinder. For this purpose the piston is fitted so tightly in the faucet as to move only under considerable pressure. The needle should be of steel, properly hardened to give the requisite durability. To prevent displacement when it is drawn back past the outer face of the diaphragm e, the hole in the latter may be punched from the front side, leaving a burr to support the point of the needle. The cylinder G is placed near the top of the faucet in order that the coin, though fitting snugly in the slot 0, may be pressed home with the finger.

The apparatus above described, as will be seen, permits the escape of a certain limited quantity of liquid for a definite sum of money. Being to that extent automatic it dispenses with the need of attention from the proprietor or his assistant, saving thereby the labor of one man.

fixed quantities.

As it is often necessary to draw 0d a larger quantity, the faucet is provided with a secondary cock, B, behind the ordinary servicespout B. The former has a hollow plug, L, its end opening into the interior of the fancet, and with an. orifice at one side. It is held snugly in position by the spring iand washer it. To the stem is secured a crank-lever, provided with a handle, M. To prevent this being manipulated by any beside the person in possession provision is made for look ing it when closed. One of a simple kind is shown in the handle, being a spring-bolt adapted to slip into the nozzle when the handle is in that position. A permanent lock is shown at the backof the cock, and is also very simple in its construction. Itconsists of a short coilspring, with one end fastened to the cock or faucet, and the other and outer end, after forming an inwardly-projecting lateral loop, 1), turning at right angles through the shell of the cock, and as a bolt projecting into The device may be applied to all liquids, and especially beverages sold in a hole in the plug. The bolt is released by a key having a spirally-formed lip, h, which passes under the loop 9, and forces it outwardly as the key is turned.

Having thus described myinventio11,what I claim as new, and desire to secure by Letters Patent, is

1. In a faucet, the combination of tube A, having spout B, and slot 0, the piston-head F, cylinder G, plunger H, stud b, and lever J, substantially as shown and described.

2. The combination of tube A, having slot 0 and discharge spout B, piston head F, cylinder G, having perforated diaphragm e, plunger H, with means for moving it back and forth, slotted plug K,and cash-receptacle E, substantially as shown and specified.

3. In a faucet, the cash and liquid regulating piston, consisting of the adjustable heads F F, the cylinder G, in two parts, connected by lugs a a, and provided with a perforated diaphragm, e, and a movable plunger, H, all constructed, arranged, and adapted to operate substantially as set forth.

4. In combination with a cash receiving and discharging and a liquid-measuring piston, substantially as described, the faucet-tube A,having cash receiving and discharging slots 0 f, discharge-spout B, and lateral conduit D,

substantially as set forth.

5. In combination with an automatic cashreceiving and liquid-measuring faucet, substantially as specified, the supplemental 'cock B, adapted to be looked, as set forth.

6. In combination with a cash-receiving and liquid-measuring faucet,as described, the supplemental cock B,having lock 9, substantially as set forth.

7. In combination with a cash-receiving and liquid-dispensing faucet, as described, the supplemental cock B, having handle M, provided with bolt N, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
