VENDING-MACHINE.

SPECIFICATION forming part f Letters Patent No. 496,281, dated April 25, 1893.

Application filed February 20, 1893. Serial No. 463,128. (No model.)

.To a/ZZ whom it may concern:

Be it known that I, HARRY D. PUEsELL, a citizen of the United States, residing at Washington Court-House, in the county of Fayette and State of Ohio, have invented certain new and useful Improvements in Vending-Machines, of which the following is a specification.

The primary object of my invention is to provide a machine which will discharge postage stamps upon dropping a nickel in a slot.

The various features of my invention are fully set forth in the description of the accompanying drawings making a part of"this speciiication, in which- Figurelis an elevation of my improvement inclosed in a case with the front removed. Fig. 2 is a central vertical section of Fig. l. Fig. 3 is a section on line Fig. 2. Fig. 4 is a perspective view of the package carrier. Fig. 5 is a detail sectional view, showing the devices for exposing the coin last inserted into the machine.

1 represents the case in which the vending machine is arranged.

2 represents a Wheel or drum mounted upon an axis 3, which revolves in journal boxes 4.

A represents clamping jaws in which the article B to be vended is carried; a series of these jaws is arranged around the periphery of the drum 2. The clamping jaws are composed of two sections a, b; the section a being preferably rigidly attached to the periphery of the drum, and the section b hinged thereto by pivots c.

e represents a spring attached between the jaws and so disposed as to normally hold them closed.

O represents a tripping arm attached to the hinged jaw b.

5 represents a chute projecting up through the top of the case to slot 6 into which a coin is dropped for tripping the locking mechanism and moving the drum one step. Said chute 5 is hinged upon the axis 3; the top of the case is provided with a slot `or recess 7 so that said chute can be moved against the pressure of the spring 8.

9 represents the coin which drops upon a stop 10 and engages with one of the series of teeth 11 attached to the rear face of drum 2', as shown 'in Figs. 2 and 3. Now when the chute 5 is moved against the spring the coin 9 catches one of the teeth 10 and moves the drum one step, when the coin being released from pin 10 drops out into the compartment 12.

13 represents a trip beneath the periphery of the drum against which the arms C of the clamping jaws are successively carried. As the arm C strikes the trip, the jaws are opened and the package B discharged into the compartment 14 which is provided with a suitable opening for discharging it from the case. This movement carries the particular tripping arm past the spring stop 13 which goes back into position for the tripping of the next set of jaws.

15 represents a chute on to which the coin is dropped to direct it into the compartment 12.

It is desirable to have an automatic means of indicating when the charge of packages has been delivered, or when the drum is empty; this I accomplish by the following instrumentalities: 16 represents a hinged door which is normally held closed by the catch 17. 18

yrepresents a finger attached to the casing and resting upon the face of the drum. 19 represents a tripping rod adapted to engage therewith this tripping rod preferably carries the catch 17, so that when the wheelis turned un'- til the tripping lug 20 is brought round opposite the finger 18 it will raise said finger and with it the tripping rod 19 and disengage the spring catch 17 'by lifting it up, when the door 16 will drop down closingthe slot and thereby showing that the wheel has made one revolution and discharged all of its packages. 21 represents a spring friction brake engaging with the surface of the drum disk, preventing the drum or wheel from turning except through the force of the lever spout 5. 22 represents a guide for discharging the package B out of the orifice 23. I have not shown in the drawings a door or opening into said case for loading the jaws, but a door may be used, or the entire front face removed, as desired.

It is desirable to have the vending machine expose the coin last inserted and then to automatically dump said coin as the next one is put in and the mechanism actuated to deliver a package; to accomplish this result I pro- IOO vide the following instrumentalities: f represents a series ot' pins inserted in the back of the drum 2; these engage successively with the tripping lever g. h represents a connecting rod hinged to the dumping lever i; said lever is provided with the fork 7a engaging over a pin 'a projecting from the pivot shelf m on which the coin is deposited as shown in Figs. 1 and 5. o represents a retractile spring secured to the bottom of the case and the 1ever t' for bringing it back into position and raising the shelf m up in position to hold the coin for exposure; an Ordinar glass being of course provided in the case opposite the shelf m.

The general features of the moving mechanism are substantially the same as shown in Letters Iatent No. 432,139, granted me July 15, 1890, but with improvementsin details of construction.

The operation is as follows: The seveial jaws are each supplied say with two postage stamps, which are preferably placed in an envelope and the envelope inserted between the jaws cui); when the drum has been loaded it is brought to a starting position, say the jaw A brought opposite the spring trip 13; when the coin is dropped into the chute 5 it arrives at the position shown in Figs. 2 and 3; the chute is then moved by hand, swinging in the slot 7 which carries the said jaws A past the tripping lug 13, opening up the jaws and dropping the package into the compartment 14; and discharging the coin on the shelf m from spout 15, and it is carried into the compartment 12 by the lever z'- which is operated automatically and successively by the pins f and tripping arm g and connecting parts as before explained; after the coin is discharged on to chute 15 the chute 5 may be moved freely without moving the vending wheel. A second coin is dropped causing an engagement of the lever through the coin with the teeth 11 and a second movement of the vending wheel will take place. Vhen the wheel has been turned entirely round so that the last package has been discharged, the tooth 20 will engage with the finger 18, lifting the tripping rod 19 and dropping the door 16, thereby indicating that the packages are all delivered,and it is refilled and started as before.

Having described my invention, what I claim is 1. In a vending machine, the combination with the casing of a rotating drum, a series of carrier jaws a, b, adapted to engage and hold the article to be vended, rotating mechanism brought into engagement by means of the coin chute lever 5 and the tripping mechanism for opening the jaws successively as said drum is successively moved, substantially as described.

2. In a vending machine, the combination ot' the rotating drum having a series of teeth 11, the lever chute 5, a stop 10, and a series of spring holding jaws a, b, arranged around the periphery of the drum, arm C, and the spring trip 13, substantially as described.

3. In a vending machine, a drum 2 mounted upon an axis provided with a series of spring clamping jaws a., b, tripping mechanism opening said jaws at the particular point of rotation, a chute lever 5 and means for bringing a coin dropped into said slot in engagement with the teeth for moving the drum one step, substantially as described.

4. In a vending machine, in combination with the rotating drum 2, a series of spring jaws a, Z), arranged around the periphery of said drum, and adapted to clasp and hold a package, and means for tripping said jaws successively as the drum is rotated, substantially as specified.

5. In a coin-vending machine, the combination with a casing, and acoin-chute, of a door 16 adapted to drop down when released for closing the coin-chute, a trip-rod 19 for holding the door in its open position, and a rotarypackage-carrier-drum having a trip lug 2O to move the trip-rod and release the door, so that the latter drops downward and closes the coin chute, substantially as described.

G. In combination with a vending machine containing a rotating drum 2, the series of pins arranged around said drum, a tripping lever g, a dumping lever t' hinged to the shelf on, and means for bringing the said parts back into normal position as the pins successively pass the tripping levert, substantially as described.

In testimony whereof I have hereunto set my hand.

HARRY D. PURSELL.
