INVENTORS ATTORN Patented Mar. 10, 1931 UNHTED STATES EUGENE H. PRESCOTT AND WILLIAM G. LEAZAR, OF KERRVILLE, TEXAS VENDING llIACI-IINE FOR FILLING CIGARETTE LIGHTERS Application filed July 15,

This invention relates to new and novel improvements in slot machines, and more particularly to that class of machines for dispensing predetermined quantities of liquids.

The primary object of the invention is to provide a slot machine for delivering liquids for replenishing cigar, cigarette and pipe lighters. The machine consists of a mechanism including parts whereby upon deposit of a proper coin therein a certain quantity of liquid is automatically released to the lighter.

Another object of the invention is to provide in the machine a mechanism of durable and positive action and designed to carry out its functions in a practical and eificient manner.

With the above and certain other features in view and which will become apparent as the description proceeds, the machine and its operation will be clearly understood from a perusal of the following explanation, together with the drawings and wherein:

Figure 1 is a top or plan view,

Figure 2 is a cross-sectional view taken on the line 22 of Figure 1, and partly broken away,

Figure 3 is a partial vertical sectional view, taken on the line 33 of Figure 1,

Figures 4, 5, 6 and 7 are detail sectional views of the machine, Figure 8 being a perspective view of a coin ejecting lever.

Referring more closely to the drawings, 1 denotes the frame of the machine and 2 the base. A covering, not shown, but of any preferred construction maybe provided to enclose the mechanism.

To the rear side of the frame is fastened a liquid tank 3, with filler cap 4, the tank being supported on brackets 5.

At the front corner of the frame is a coin slot 6, the coin 7 indicated by broken and full lines in Figure 7. The coin upon deposit" in the machine follows the chute 8 and comes to rest upon a dog 9. The dog 9 is under spring tension 10, until released by a lever 11 and its co-acting element 12, see Figure 8. The element 12 is bent at right angles to form an inwardly projecting end 13 which upon downward movement of the lever 11 comes in contact with the coin 7 and forces the coin into 1929. Serial No. 378,461.

a coin box. The actuation of the lever 11 to move element 12 downward is had through the bar 13a, loosely connected to element 11 by a pin 14, the lever 11 having its free end connected to the frame 1, see Figure 6. A spring 15 holds the lever 11 in normal position.

In Figure 1 the dog is shown in locked engagement with a disk 17 carried on a main shaft 18 journalled in the sides of the frame. The shaft has a crank 19 and includes a ratchet 20 co-acting with a pawl 21 to prevent reverse rotation of the main shaft 18.

The shaft 13 also carries a cam 22 under spring tension no, the object being to kick the shaft 18 slightly to the right to start it on a right hand revolution.

Following the preceding it will be apparent that when a coin is dropped upon the dog 9 and the lever 11 depressed, the coin and lever will force the dog from the notch 9a in the disk 17. The coin is then deposited into a coin box and the disk 17 is free to rotate with the shaft 18 by turning the crank 19 to deliver a quantity of liquid. The remaining parts of the mechanism for bringing this about will now be explained in detail.

Connected to the tank 3, see Figure 2, is a valve 24 and to this valve is connected a measuring receptacle 25 having an outlet tube 26. Gonnected to this tube is a delivery valve 27. A tube 27a delivers the liquid to the purchaser. The means for operating the valve 24 is through a cam 29 carried on the shaft 18 and enacting with a slide bar 30 and pivoted lever 31, the latter under spring tension There is also provided a means for permitting air to enter tank 3 to facilitate the flow of liquid at each delivery. This arrangement is carried out by means of a small slide valve 33, carried on a pipe 34 the pipe connected to the tank 3, and having a lateral tube connection 35 leading to the measuring receptacle 25. Air is admitted through the opening 36. This valve is opened by means of a cam 38 on shaft 18 in connection with an upright member 39, pivoted at 40 to a rigid support 41. The upper end of this member 39 is under spring tension of a coiled spring a9.

tension 42 when the valve is operated and when so moved inward by the cam 38 it shoves inward a rod dd and moves the link 45 thus opening the valve 33.

The measured quantity of liquid .is now ready to be released to the customer through tube 27a. This tube may be reduced at extreme outlet in order to reduce flow.

This is acconmlished through the gears 45 and d6, gear 4L5 carried on shaft 18 and in mesh with gear 4E6 when the machine is operating. The gear 46 is mounted on an upright valve stem 48 of valve 27 and is under The gear 46 has one tooth 50 longer than the other teeth and on contact with the stop 51 stops this gear when the valve 2? is opened. In this conne tion and in closing the valve 27, the gear 45 is minus one tooth, and the space A will throw the gears out of mesh when this point is reached. The spring 49 will then close the valve 27 after the liquid has been delivered.

The operation of the parts in depositing the coin, releasing the dog, and opening and closing the valves is practically simultaneone and when the crank has made one turn to effect one revolution of shaft 18, the dog again falls into the notch in the disk 17, thus locking the machine. The gears are also again placed in mesh and the machine is ready to serve the next customer. When the coin is deposited and the lever 11 depressed, the dog 9 is released from the disk 17 and remains just out of the notch, held so by the tension of spring 49 acting on the shaft 18 until the crank 19 is operated to work the mechanism.

It is believed that further explanation of the operation of the machine will not be necessary.

It is also obvious that the different parts of the mechanism are capable of considerable variation and modification, such changes to come within the scope and meaning of the appended claims.
