VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 611,226, dated September 20, 1898. Application filed February 8 1897. Serial No. 622,408. (No model.)

To all whom it may concern.-

Be it known that 1, HENRY G. SWEENEY, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Vending-lllachines, of which the following is a specification.

This invention relates to certain improvements in machines for vending or dispensing liquids. Some of its features relate to the construction of the coin-controlling mech-' anlsm.

The object of the invention is the production of a machine which shall be simple and economical of construction, durable, have small liability to get out of order, and which cannot be successfully tampered with or robbed of its liquid.

The nature of my improvements is illus trated in the accompanying drawings and also fully set forth in the description given below.

In the drawings, Figure l is a vertical section of that portion of a liquid-vendingmachine to which my improvement relates, show-' ing the coin mechanism in its normal position. Fig. 2 is a similar section to Fig. 1, partlybroken away and showing the coin mechanism at the conclusion of a delivery. Fig. 3 is a horizontal section showing the coin mechanism in its normal position. Fig. 4 is a longitudinal section of the valve used in the form of apparatus shown at Fig. 2. Figs. 5 and 6 are transverse sections of the same valve, showing'its different positions. Figs. 7 and 8 are cross-sections of valves used in the apparatus of Fig. 1.

In said drawings, A represents the case or box of the machine, only one side thereof being given. B represents the coin-chute, and O is the receiver into which the coin falls from the chute. The receiver is mounted upon the end of an arm 0, fast upon the pivot 0 supported by a bracket C risingfrom a horizontal frame 0 attached to the case A. A forked dog 0 also mounted on said pivot and projecting therefrom in the opposite direction from that of arm 0', is adapted,'when' a coin is dropped into the receiver and depresses it and arm O,'to lift the locking-detent .D, loosely supported upon pivot 0 out from engagement with the ratchet-wheel D, revolving upon journal D supported in frame 0 In the performance of this duty one arm of the dog encounters an overhanging arm or projection D attached to detent D, and by such engagement operates the detent. The wheel is a double one, having on one-side of its periphery a series of teeth D for engagement by said detent in stopping the wheel at the conclusion of a delivery and on the other side a series of teeth D for engagement by the pallet D in moving said wheel. Said pallet is freely pivoted upon one end of an elbow lever D swinging upon pivot D supported in frame 0 and the other end of said lever projects through the case A, as shown, to permit it to be operated. The lever is depressed by the purchaser to the position shown at Fig. 2, and thereby causes a partial rotation of wheel D, and at the conclusion of the stroke so imparted the lever is lifted to its normal position, given in Fig. 1, by a spring D one end of which lifts upon the projecting arm of the lever.

. The pallet D5. carries alaterally-projecting ,pin D which when the pallet is drawn forward by the operating-lever enters the fork of the dog 0 and by its engagement therewith 'causes the swinging of the coin-receiver from the position of Fig. 1 to'that of Fig. 2, so that th'ecoin will be discharged from the receiver. This pin also forces the receiver back toits normal. position by its engagement with the dog during the retraction of the pallet. The ratchet-wheel can be rotated in one direction only-viz, the forward directionas a gravity-stop D pivoted upon frame 0 engages the teeth- D and absolutely prevents any backward movement whatever.

Power is carried from the pallet-wheel to the valve or valves controlling the liquid by the following devices: A swinging lever E, pivotedat E to frame 0 carries upon its upper end a cam E made fast by rivet E and encountering two series of alternately-actingpins E and E carried by and proj ectingfrom the side of ratchet-wheel D. -As shown at Fig.1, one-of the series E of the pins is in contact with the under surface ofthe cam and in such relation thereto that any forward movement of the wheel will cause the cam to exert a pressure against lever E, which will result in its moving to the position given in broken lines in said figure and in full lines at Fig. 2. The movement of the wheel brings one of the pins E close against the cam, as seen at Fig. 2, so that at the next impulse given the wheel said pin will carry the cam and lever E back to their former positions, (shown at Fig. 1,) the cam and lever being thus left at the conclusion of each operation in proper positions and ready for the next operation. The movements thus given to lever E are carried to the crank-arm E on the stemvalve by a connecting-rod E".

In Fig. 1 I have illustrated a form of apparatus to be used in dispensing liquids which are under pressure when fed to the measuring-receptacles of the machine. I prefer to use duplicate receptacles, such as F and F, and to employ therewith a single valve adapted to permit the filling of one of the recepand F connecting the valve with the measuring-receptacles, the feed or supply pipes F and F one for each receptacle, and the delivery-pipe F. Of these pipes F and F are close together, so as to be controlled by one of the cross-passages of the valve, and the pipes F and F are similarly arranged, so as to be controlled by the other cross-passage. When these pipes are in the same vertical plane, the construction of valve shown at Figs. 5 and 6 is used; but when located in different planes a valve like that at Figs. 7 and 8 is used, the fluid-passages therein being located in planes corresponding to those of the pipes, and a'Y, like that shown at M,being also used to connect both ends of the valve with the discharge-pipe. The valve, whichever form is used, has two positions, as will be understood, and in each of them it acts to deliver the charge contained in one of the receptacles and simultaneously permit the filling of the other receptacle, and it is oscillated from one to the other of these positions at each operation of the actuating mechanism by a purchaser. Subsequent operations will be mere repetitions of those described, and each of them leaves the valve in readiness for the next operation without any intervening positioning movement of any description.

In the apparatus shown at Fig. 1 a ventvalve H is placed at the top of each of the receptacles, and its stem is provided with a crank H, which is connected by a rod H with a crank H upon the stem of the main valve. These vent-valves are adapted to admit air at the top of the receptacles and above the liquid at the time the latter is discharged, and my object in employing them is to insure the prompt discharge of the entire body of the liquid and prevent as far as possible any dripping or after drainage which will tend to keep the machine untidy. I find that the use of this vent causes the quick delivery of the entire body of the liquid, so that but little or no after dripping occurs.

In Figs. 2 and 4: an apparatus is shown adapted to dispense mixed drinks, the measuring-receptacles for the main liquid being similar to that used in the other apparatus, except that they are provided with permanently-open vents H instead of the valved vents of Fig. 1. The liquid-supply is kept in a tank J, connected to the valve by supply-pipes in the usual manner. The flavoring extract is also measured in corresponding companion cups or receptacles, one of which is shown at K, and such receptacles are connected by pipes L to the valve G. The pipes from the receptacles F F in this apparatus join the valve opposite one set of passages G at one end of the valve, and the pipes from receptacles K join it opposite another set of such passages at the other end of the valve, as will be understood from Fig. 4c, the Y (indicated by M) connecting both ends of the valve and causing the intermingling of the main fluid and the flavoring extract as soon as the valve is operated to effeet the discharge.

I claim 1. The combination in a liquiddispensing machine, of companion measuring-receptacles for the main liquid, both connected to the supply and discharge, companion measuring-receptacles for the flavoring-syrup also connected to the supply and discharge, an oscillating valve controlling all said receptacles and having two positions in each of which it permits the discharge from one of each pair of said receptacles and the filling of the others, and coin-controlled mechanism for operating said valve alternately in opposite directions, substantially as specified.

2. The combination in a machine for dispensing mixed beverages, of two companion measuring-receptacles for the main liquid, two companion measuring-receptacles for the flavoring-syrups, a valve provided with two cross-passages connecting with said main receptacles and with two other cross-passages connecting with the syrup-receptacles, and coin-controlled mechanism for operating said valve, substantially as specified.

3. The combination in a machine for dispensing mixed beverages, of two companion measuring receptacles for the main liquid both having connections with a source of supply and with the discharge two companion measuring-receptacles for the fiavori ng-syrup, also connected to a source of supply and to the discharge, and a single valve controlling all said connections to the sources of supply and to the discharge, substantially as specified.

4c- The combination in a machine for dispensing mixed beverages, of two companion measuring-receptacles for the main liquid both having connections with a source of supply and with the discharge two companion measuring-receptaclesfor the flavoring-syrup, also connected to a source of supply and to the discharge, and a single valve provided with two cross fluid-passages controlling the admission and discharge from the main liquid-receptacles and two other cross fluid-passages controlling the admission and discharge from the syrup-receptacles, substantially as specified.

5. The combination in a machine for dispensing mixed beverages, of two companion measu-ring-receptacles for the main liquid, both having connections with a source of supply and with the discharge two companion measu-ring-receptacles for the flavoringsyrup, also connected to a source of supply and to the discharge, and a single valve controlling the admission and discharge from all the receptacles, and allowing one of each pair of them to fill while the others are emptying, substantially as specified.
