VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 402,515, dated April 30, 1889. Applicationfiled June 13, 1888- Serial No. 276,961. (No model.) Patented in England July 21, 1887, No. 10,232.

To alZ whom it may concern.- Be it known that LPnnolvAL EVERITT, subject of the Queen of Great Britain, and a resident of London, England, have invented certain new and useful Improvements in Maapparatus for the delivery of a given quantity of "liquid in exchange for a coin, and I claimed certain improvements therein set forth.

My present invention relates to certain improvements whereby in such an apparatus mechanism is released by the insertion of the coin or token, and thereby a pump is caused to operate and to eject agiven amount of the liquid through a nozzle or faucet, and whereby'the mechanism is reset to be again oper ated by the insertion of another coin, and

.to certain improvements whereby the coinaperture of automatic machines of this character is closed when the weight or spring which operates the mechanism has ceased to work, and to certain improvements in the construction of the nozzle.

In order that these improvements may be fully understood, I describe my invention and refer to the accompanying drawings as representing one means for carrying it into effect, though it is obvious that modifications may be made therein tomeet'special requiretained by dropping a coin in a coin-aperture.

Fig. 2 is a vertical sectional elevation through the center of the top part of the apparatus along the dotted line A B in Fig. 1. Fig. 3 is a vertical sectional elevation along the dotted line C D of Fig. 2. Fig. 4 is a vertical sectional elevation along the dotted line E F of Fig.2. Fig. 5 is a cross section of the top of the nozzle, (numbered 12 in Fig. 3.) Fig.

6 is a sectional elevation of the coin-aperture with shutter closed, (shown in Fig. 2 with shutter open.)

Similar numbers in all the figures represent similar parts.

The mechanism is contained in a suitable case (shown in Fig. 1) having a door, 1, to permit access to the interior for the purpose of attaching the case to the stand or column which contains the weight 18, Fig. 3, and the lock-bag 2, Fig. 2, or other receptacle into which the coins are dropped.

The liquid to be delivered is contained in a tank, 3, Figs. 2, 3, and 4, placed within the frame-work 4 and 4 of the apparatus. The pump 7 is so placed with reference to the tank that the liquid flows by gravity through the tube 6, Fig. 2, into the chamber 8, Fig. 3.

nozzle 11 is opened, and the liquid is ejected in a thin stream or spray from a suitable aperture at 12 on the end of the nozzle.

Beneath the nozzle is placed a suitable receptacle, 40, Fig. 1, to receive the spray as it descends. At points14 14, Fig. 3, around the middle portion of the nozzle are holes connecting with airv passages 13 and 13, Fig. 3, and having openings on the top ofthe nozzle and around the spray -aperture '12, Fig. This arrangement is to prevent persons from obtaining the liquid by suction at the nozzle. Any suction exerted at the nozzle would draw air from the air-tubes. which air \muld enter at theopenings 14 14, 3, instead of liquid from the nozzle.

The plunger 9 is connected by a rod, 15, to a crank disk or eccentric, 16, which is on a spindle that carries a pinion, 45, Fig. 2, gearing with the wheel 46, which is connected by means of a pawl, 47, Fig. 3, and ratchet-wheel 21 to the drum 17, on which is wound the cord or its equivalent that carries the weight 18, that acts as the motive power of the mechanism. The drum 17 is fixed to the spindle, which has for convenience in winding up the mechanism a wheel, 19, Fig. 2, at one end, and the other end, 20, Fig. 2, so shaped as to receive a key.

The ratchet-wheel 21 prevents the reversal of the mechanism while it is being wound by engaging with the ratchet 47, the ratchet 47 being fastened, as shown in Fig. 3, to the wheel 46, and the ratchet-wheel being fastened to the axle, of which the end 20, Fig. 2, is one terminus, while the wheel 46 is free to move upon the same axle. The obvious tendency of the weight is to keep the pump always working; but it is only permitted to make one double stroke at a time 011 account of the escapement 26, Fig. 3, which, when the plunger 9 is at the top stroke, as represented in Fig. 3, comes in contact with a stop-pin, 22, and so prevents the further descent of the weight until the escapement is moved. This movement of the escapement is accomplished when a coin or token is dropped through the coin-aperture 32, Fig. 2, and the coin-chute 48, Fig. 2, into the coin-bucket 23, Figs. 2 and 4, thus depressing the bucket, which actuates the arm 24, Fig. 4, and rod 25, Figs. 4 and 2, connecting with the escapement. The escapement is a double one, so that when the escapement is released and the eccentric 16 moves around the pin 22 comes in contact with the curved end 26 of the escapement, the rod is actuated, and the coin-bucket is replaced in position, while the escapement itself goes into its first position, as

represented in Fig. 3, and stops the pin 22 as soon as it has completed its revolution. The coin when dropped into the bucket is prevented from falling through the open bottom of the bucket by the fan-shaped catch 27. This catch is pivoted at 59 and has a projecting pin, 60. A finger or catch, 56, is loosely pivoted at 59 and rests upon a projection, 57, of the pin 60. As the bucket descends, the finger or catch 56 strikes the pin 58, which projects from the frame-work at a suitable point, and the finger 56 is thereby raised without disturbing or moving the fan-shaped catch 27, and upon passing the pin 58 the finger 56 again rests upon the projection 57; but upon the bucket being replaced in position, as above described, and during its upward movement, the finger 56 again engages with the pin 58, and the pin 60 is thereby depressed, thus raising the fan-shaped catch 27 and releasing the coin from the bucket. The weight of the fanshaped catch 27 carries it back to its original position. The coin when released from the bucket falls through the chute 28, Figs. 2 and 4, into the lock-bag 2 or other receptacle. The weight 18, Figs. 3 and 4, is preferably not attached directly to the cord 29, but the cord is passed around a pulley, 30, attached to the weight, and then is fastened to the short arm 34, which is attached to the frame-work. This arrangement winds from the drum a length of cord equal to double the distance descended by the weight. hen the weight has run down to the full extent, the mechanism will no longer work, and it is important to pre vent the insertion of more coin. This is accomplished by the shutter device shown in Fig. 6 and in the upper portion of Fig. 2. The shutter 31 is carried by the fixed arms and 49, so that it can move across the coinaperture An expansive spring, 33, presses against the frame-work at 51 and at its upper end against the milled disk 52, which is fastened by a screw-thread to the rod 53. This spring 33 thus tends to raise the lever 54, and so to throw the shutter 31 over the coin-aperture 32, the end of the weight-cord 29 being attached to the arm 34, which arm is made sufficiently long to overcome the spring. It is evident that while the weight is in suspension the shutter 31 will be drawn back and the coins may be freely inserted; but as soon as the weight has descended and come to rest at the bottom of the apparatus the spring 33 comes into action and throws .the shutter 31 over the coin aperture 32, and it remains closed until the machine is wound up.

The case 35, which covers the mechanism, is fixed by suitable means to the metal ring 36 36, which fits on the frame-work 4 4. The case 35 is provided with a suitable opening at its top or apex, and the cap in which is the coin-aperture 32 is adapted to slip into this opening and to be screwed on the frame-work within,thus holding the case 35 in place. The arm 44 supports the dish 40, which receives the spray as it descends from the nozzle 12.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a liquid-vending machine having an aperture for receiving a coin, a pump, a weight adapted to operate the same, and an automatic locking device arranged to prevent the operation of the pump.

2. In a liquid-vending machine having a coin-aperture, a pump operated by a weight, an escapement engaging the same, a lever arranged to release and to reset the escapement, and a coin-receptacle attached to said lever which is depressed by the weight of a coin passed through the coin-aperture.

3. The combination of the pump 7, the weight 18, and cord 29, operating the same, the crank-disk 16, the escapement 26, the levers 24 and 25, and the coin-bucket 23.

4. In combination with a case provided with a coin-aperture, a pump operated by a weight, a disk and escapement arranged to be released by placing a coin in the coinaperture, and a projection on the disk, whereby the escapement is returned to its position and the escapement reattached to the disk, substantially as described.

5. In a liquid-vending machine having an aperture for receiving a coin, a pump, a weight adapted to operate the same, and a coin-receiver arranged so that when a coin is placed within the receiver it shall release the weight and permit the pump to be operated.

6. The combination of a case provided with a coin-aperture, a pump, a tank so placed that the liquid therein flows by gravity into the chamber of the pump, a crank-disk connected with the pump, a weight and cord actuating IIO the crank-disk, a coin-bucket, and suitable levers connected With an eccentric and escapeinent on the crank-disk, as and for the purpose set forth.

7. In a liquid-vending machine, the combination of a case provided with a coin-aperture, mechanism adapted to be operated by a Weight, a coin-receptacle arranged so that when a coin is placed Within the receptacle it shall release the Weight and permit the device to 'be operated, and a closing device adapted to shut the coin-aperture when the weight has ceased to act, substantially as described.

8. The combination of a case provided with the coin-aperture 32, the shutter 31, closing the same, the spring 33, connected with the shutter by suitable levers, and the Weight and
