VENDlNG-NIACHBNE Specification of Letters Patent.

Patented April l0, 1906.

Application filed February 2l| 1905. Serial No. 246,649.

To a/ZZ whom it may. concern:

Be it known that l, OSCAR K. SLETTO, oi Blackduck, Beltrami county, Minnesota, have invented certain new and useful Improvements in Vendinv-Machines, of which the following is a specication.

My invention relates to vending-machines designed particularly for delivering snuff, but also adapted for dispensin drugs, spices, and similar articles in a groun or pulverized condition.

The primary object of the invention is to provide a machine of simple but strong and durable construction for use in a grocery or drug store for delivering with each operation a measured quantity of a certain value of snuf, spices, or dru s, thereby rendering it .unnecessary for the c erk to measure or weigh the article with every purchase, each operation ofthe machine dehverin a certain quantity according to the size of t e feed-pockets.

A further object is to provide a machine which while intended primarily for delivering a commodity with every operation of a lever can be easily modified to require the deposit ofthe coin as a condition precedent to the operation of the machine.

Other ob'ects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described, and vparticularly pointed out in the claims.

ln the accompanying drawings, forming part of this spec1fication, Figure 1 is a vertical section of a snuff -vending machine embodying my invention and of a jar in an inverted delivering position thereon. Fig. 2 is a vertical section on the line of Fig. 1, with the jar shown in Jull lines. Fig. 3 is a plan view of the machine with the snuH-j ar removed. Fig. 4 is a vertical section on the line y 'y of Fig. 1. Figs. 5 and 6 are details of the locking mechanism and illustrating the manner of tripping it by the deposit of a coin. Fig. 7 is a vertical section through the machine, showing its periphery constructed without the employment of the coin-controlled mechanism.

ln the drawings, 2 represents a suitable base having a coin-receptacle 3 and a casing 4, hinged to the base at 5 on one side and provided with a lock 6 on the opposite side to prevent any unauthorized person from obtaining access to the interior of the machine and the coin-receptacle. The casing 4 incloses the operating mechanism of the machine and may be tilted to one side on the hinge 5 to allow access to the interior. A rock-shaft 7 is mounted horizontally in the casing 4 and has a bearing at its inner end in a casting 8, that is secured to the cover 9 of the casing. A circular hopper 10 is mounted on said cover over a discharge-hole 11 therein and is provided at its upper edge with a flanged extension 12, upon whichthe inverted open end of a snuff-jar 13 is placed and held against accidental dislodgment therefrom by set-screws 14. A wheel or drum 15 is loosely mounted on the sha-ft 7 and provided on its periphery at intervals with a series of depressions or pockets 16, that are curved at the bottom .and are adapted to contain a quantity of snuff or other material that is being sold corres onding in value to the denomination oft e coin placed in the machine. The wheel 15 revolves in a vertical plane between guides 17 and beneath the opening 11 in the bottom ofthe hopper, said opening corresponding in length substantially to the length ofthe ockets or recesses in the wheel. The snuii fe into the hop er from the jar above will fall down into tliese 'recesses be tween the guides, which will prevent it from working out of the pockets at the sides of the wheel. An opening 18 is provided in the casing 4, through which the wheel operates, and a shelf 19 is provided beneath the opening on which a portion of the snuff will be deosited from the overhanging pocket, and trom which shelf and pocket the article purchased can be readily removed.- I prefer to have the feed-wheel operate through the opening in the outside casing of the machine, so that in vending snu or material of like consistency, which will not flow readily, the receiving pockets or recesses of the feed-wheel will be eX osed through the opening in the casing an allow the removal of their contents. Asuitable operating-handle 20 is provided on the shaft 7, having a limited travel between stops 21 on the machine-casing. An arm 22 is secured on the shaft 7 and connected with a spring 23, whose tension tends to hold and return the operating-lever and shaft to the position indicated in Fig. 3. The wheel 15 being loose on the shaft 7 is free to make a complete revolution and is provided with a IOO hub 24, having on one side a series of (preferably four) teeth 25 and a series of lugs 26, arranged opposite said -teeth and near 'the periphery of the hub and inclosing the teeth 25 and equidistant from the contiguous ones. A spring 26 en ages the teeth 25 and prevents backwar movement of the Wheel. Stops 27 are provided on the periphery of the hub, and one of them is normally engaged by a locking-pawl 28 on a fixed pivot and having a beveled face 29. A lu 30 on the arm 22 extends inwardly towar the teeth 25 and the lugs 26. A coin-slot 31 is provided in the casing above the teeth and the lug 30, and when a coin is deposited in this slot it will drop down upon one of the teeth between the lug 30 and one of the lugs 26. Then when the shaft 7 is oscillated the edge of the coin Will enga e the beveled edge 29 of the pawl 28 and li t it sufficiently to clear the stop 27 and unlock the shaft. The Wheel and hub make a quarter-turn With each complete stroke of the o eratin -lever, and each movement of the W eel de ivers a quantity of snuff or other material and sets the machine anew for another coin.

In a machine of this kind used for vending snuff or similar ground or pulverized material it is desirable, if not necessary, to provide some means for stirring or agitating the niaterial in the hopper and jar to insure its proper feed to the delivery mechanism. I therefore provide a gear 32 on the inner end of the hub 24, meshing With a pinion 33 on a shaft 84, that is mounted in the casting 8 and extends up through the top plate 9 into the hopper 1U. irritating arms or fingers 35 and 36 are provide on the upper end of the shaft 34, both arms being serpentine in form and the former being arranged to agitate or stir the material in the hcp er, While the latter arm is longer and exten( s up into the inverted ljar to loosen and stir up the material therein. Snuff and similar commodities Will have a tendency to ack down and become lumpy in the jars, and) these agitating-arms serve to eiiectually break u the lumps and loosen the material sufficient y, so that it Will feed by gravity down to the delivery-Wheel. I also provide on the upper end of the shaft 34 a sweep 37, that moves over the bottom of the hopper and pushes Venough snuff or other material ahead of it to insure the iillin of each exposed pocket of the delivery-W eel and smooth off the top of the discharge, so that a comparatively uniform quantity Will be delivered With each quarter-turn of the Wheel.

The manner of using the machine is as fclloWsz-The snuff-jar having been opened and inverted over the hopper and secured thereon the person desiring to make a purchase will deposit a coin of the pro er denomination in the slot. The coin will rop down upon one of the teeth 25 between the lugs 30 and one.' of the lugs 26, With the upper edge of the coin.-

the hub between projecting beyond the edge of the hub,where 1t will enga e the pawl 28 when the shaft 7 is rocked. T e operator will then grasp the handle 20 and rock the shaft, and the beveled edge 29 of the pawl 28, en aging the edge of the coin, will be lifted unti the stop, 27 is free to move without contacting with the paWl. When the Wheel has made a quarter-turn and delivered the snuff or other material, the o erator Will release the handle 20, and t e spring Will return it and the shaft to'their normal position, and as the lug 30 recedes from the tooth 25 and the lu 26 the coin will be released and allowed to rop into the receptacle beneath. The awl 28 Will then drop down upon the peripliery of the hub and be 1n position to engage the next stop and prevent a second `operation of the machine until another coin has been de osited therein.

In the preceding figures o the drawings I have illustrated my improved vending-machine used in connection with an operating mechanism that is controlled by the deposit of a coin in the machine; but I do not Wish this to be understood as my referred construction or the one that I s all generally use, as I regard the form of machine illustrated in Fig. 7 as the more practicable and the one best suited for the pur ose designed. In this :figure the same formo feed-wheel is shown except that the pockets are larger to contain a nickels worth of the article vended instead of a pennys Worth, which the pockets shown in the Wheel of the other type of machine are ada ted to contain.

The hub o the delivery-wheel is provided With a series of teeth, as heretofore described, and in place of the lug 3() a paWl 38 is pivoted on the arm 22 and rests by gravity upon said hub and engages said teeth to revolve the Wheel a quarter-turn with each o eration of the lever 20. The periphery of t e delivery-Wheel projects through the casing 4, and the contents ofthe pockets are discharged successively into a spout 89, which may be inserted into the open end of a sack in which the snuff or other article is delivered to the customer.

When the form of machine shown in Fig. 7 is employed, it will be kept on the counter, Where it is not easily accessible to the public, but Within convenient reach of the clerk to enable him to easily and quickly fill each customers order as received Without the necessity of Weighing or measuring the article,

I claim as my invention- 1.' In a vending-machine, the combination with a casing having a delivery-opening in its side Wall, of a feedfWheel havingaseries of recesses in its periphery and projecting through said opening to deliver the contents of sald recesses outside of said casing, a receptacle near said delivery-opening and wherein the material is discharged from the recesses in said Wheel, means for operating `said feed- IIC Wheel, anda hopper adapted to contain a ground or pulverized material and having a discharge-opening arranged to register successively with the recesses in said Wheel as it revolves, substantially as described.
