This invention relates to a vending machine for valve cores used in the valve stems of pneumatic tires and the like, the general object of the invention being to provide 5 means whereby a customer can secure a core by depositing a coinof the proper denomination into the machine and turning the handle of the machine.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and speciically pointed outv in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several yieWS, and in which F igure 1 is a. front view of the device, showing the interior parts in dotted lines.

Figure 2 is a section on line 2 2 of Figure l.

Figure 3 is a top plan View.

Figure 4 is a viewy similar to Figure 1, butshowing the interior parts in a different position. l

Figure 5 is a Section on line 5 5 of vFigure 2.

In these views, the numeral 1 indicates a casing which is divided by the partitions 2 into a large chamberand a small chamber. An inclined rack 3 is arranged in the large chamber, the rack comprising two members spaced apart to receive the cores, shown at A, between them, and as shown, the cores are held in upright position and they will gravitate toward the lower end of the rack.

A lever 4 has its upper end pivoted to a stub shaft 5 carried by the vertical partition 2, the lever being arranged within the large chamber, and the lower end of the lever is formed with the curved prongs 6 and 7.

The upper portionsof the prongs are bent outwardly in opposite directions from the stem so that said prongs are spaced .apart and the extremities of the prongs overlap.

The lever is so arranged that its prongs 7 58 will extend across the path of the cores and thus prevent the cores from moving onfthe rack, but when the lever is moved to the right, the prong 7 will move out of the path of the vcores and the prong 6 will be in the path of the cores and as the prongs are spaced apart a distance slightly greater than the diameter of the core, one of the cores will ymove intothe space between the prongs and be heldby lthe prong 6. Then when the lever is moved to thele'ft, the prong 6 will Ire- 60 lease the first core so that thiscore can drop from the rack, but vthe core next to the first one -will beengaged by the prong 7, So that but Zone corecan drop from the rack. Thus the oscillation ofthe lever controls the'dis- 65 charge of the cores from the rack and per-l mitlslbutf one core at a time to drop from the rac f A "A `shaft 8 is journaled in the walls Vof the front or small chamber,with itsrear end 7o' passing through the vertical partition 2 and links 9 'connect this shaft with `the upper part of -thelever 4. An arm 10 is fastened to the shaft and extends,downwardlyV into engagement with the periphery of a disk 11 75 fastened toa shaft 12 which is also journaled in the' walls of the small chamber and extends through the front wall where it receives a knob 13. The disk has a coin receiving notch 14 therein which, when the disk is in a cerso tain position, will'be located below the lower end of a coin chute 15 which depends from the top of the casing, so that a coin .dropped into the chute will enter the notch with a portion projecting above the disk, so that when the disk is turned, this portion of the coin will contact the arm 10, thus pushing the arm outwardly. This movement of the arm will partly rotate the shaft 8 and causeA vthe links 9 to move the lever 4 to a position :19.0

where the prong 6 will release a core. `lhen the disk is turned to a position to move the coin out of contact with the arm 10, a spring 16, which engages the lever, will return the parts to normal position. The coin will v finally drop from the notch into the bottom of the small chamber, from which the coins can be removed by opening the door 17 in the front of the chamber, this door being provided with a lock 18. Ratchet means,-.i f

shown generally at 19, prevent retrograde movement of the disk and the shaft 12 and the cores dropping from the rack, will fallv upon a chute 2O which will deliver the cores to a tray 2l at the front of the casing.

The top 22 of the casing is removable so that cores cany be placed on the rack and this top is secured in position by the lock 23.V

Y.aus

From the foregoing it will be seen that I have provided simple means whereby one can secure a valve core by depositing acoin in the device and turning the handle. The device can be placed anywhere desirable, such for instance, on -an exterior wall of a garage7 so that the customers can secure valve cores without going into the garage and even if the-garage is closed. A Y 1 v ItA is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the constructiony and inthe combination and arrangementy of the several parts, provided that such Changes fall within the scope of the appended claim.

Vhat I claim is A A dispensing ydevice of the class described comprising a diagonally arranged rack for holding the articles to Ybe vended, ay forked lever pivotally supported andV having its prongs curving toward each other,l with the Y prongs bent outwardly in opposite directions beyond the longitudinal plane of the lever,

#with the extremities of the prongsoverlapping, the lower endrof the rack extending betweenthe prongs and means for oscillating the lever to release the lowestY varticle on the rack while holding the next Varticle on the rack.

In testimony whereof I aflix my signa-ture.
