Be it known thatl, Crrrsren E. SMELsEn,

a citizen of the United Stat-es, residing at Shelbyville, in the county of Shelby and tate of Indiana; have invented new and useful Tmproven'ients 111 Penc1l-Lead-Vending' ltiachines, of which the following is a specification. p p p This invention" is a coin-controlled"machine for vendingleads for refillablepen-y oils; and the objectisf to provide a" small and compact device'that may be set on a' showcase or coiuiter and which'cannot be readily o'erated without the'deposit" of a proper coin. v v H v I accomplish the above and other objects which will'be hereinafter disclosed by the mechanism illustrated in the accompanying drawings, in which- Fig. 1, is a vertical section on the lines 11 of Figs. 2 and 6. Fig. 2, is a section on the lines 2-2 of Figs. 1 and 5. Fig. 3, is a section on the lines 33 of Figs. 1 and 5. Fig. 4c, is a section on the lines 33 of Figs. 1 and 5 but showing the hand-lever and associated parts in lowered position.

Fig. 5 is a front elevation of my invention and Fig. 6 is a side elevation thereof.

Like characters of reference indicate like parts of the several views.

The vending mechanism is housed in a casing 7 which rests upon a suitable base 8 detachably secured thereto by a fastening 9, of any usual or suitable construction.

Supported by and within the casing 7 are a pair of parallel plates 9 and 10, here shown as near the right side of the casing,

and at the opposite or left side is a hopper 11, the bottom of which slopes downwardly from rear to front to a slot at the lowest position through which a vertically reciprocating plunger-plate 12 is operated by means presently to be described.

The leads to be vended are deposited in the hopper parallel with the above mentioned slot and are fed by gravity to the slot. The upper edge of the plunger is beveled toward a partition plate 13 against which the plate has a sliding bearing. A wrist-pin 14 seated near the lower end of the plunger-plate passes through a slot 15 in the bearing plate 18 and is connected with a link bar 16, which in turn is pivotally attached at its other end to the long arm of a lever 17 pivoted to an extension of plate 13 as shown in Fig. 1.

The short arni of lever 17 crosses a coinslot 18, in the front ofcasing 7 and helps to form a stop to arrest the coinf Secured to the front of casing 7 are the two parallel plates 9 and 10 which have the coin-slot between them and assist in gu ding thecoin in its course; re ea e s. rear extension of plate 10is"a hand-lever 191whichpasses out through a verticalslot21lin'the front of easing far enough; to .befconveniently manipulatedi A spring 22 holds the lever norma llyagainst the upper" end of slot 21. Formed in th e lever 181a longitudinal" slot 23 through" whiclifla pin 24:, seated in a plung'e'r 25 passes. The plunger 25 has vertical movement between the two plates 9 and 10 and the plate 10 has a slot 26 through which the pin 24.- passes to the hand-lever. Another pin 27 seated in plunger 25 passes out through slot 26 to hold a vertical position of the plunger.

When the lever 19 is lowered after a coin insertion, the plunger is brought by it against the coin held by lever 17, and the lever 17 is actuated by a further downward movement of lever 19, thereby raising the plunger-plate 12 and elevating a lead to position of discharge by gravitv. into a vending trough 28. The forwardlv beveled upper end of the plate 12 causes the lead carried by it to roll off toward the front into said trough.

The discharge opening from the hopper to the trough is normally closed by a depending door 30, held shut by a spring 31 to keep the leads from being abstracted therethrough by turning the device upside down. Interference with the lead carried by the plunger is avoided by curving the lower edge of the door 30 in the manner shown in Fig. 3. The spring-actuated door 30 also acts to discharge the lead from the plunger into the vending trough 28.

As a coin is forced downward by the plunger 25, a dog 31. pivoted at 32 to the plate 10 and held in normal position by a spring 33 against the end of lever 17, is forced backward by a knife-edge 34: formed on the dog. lVhen the coin has travelled almost far enough to discharge a lead as shown in Fig. 1, the contact of the knifeedge against the coin will prevent upward movement of the coin and keep it from being thereby manipulated to discharge more than one lead. An incline 6 at the front of the casing lifts the coin off of lever 17 and rolls it back into the machine, where it drops to the bottom.

Should the lever 17 be tampered with by a pick in an effort to discharge a lead without the deposit of a coin, the hook 36 on dog 31 will arrest the lever 17 as it is forced downwardly and lock it. The underside of the end of lever 17 is beveled at 37 to more positively engage with the hook on the dog.

A curved slot 39 in plate 10 is for the passage of the knife-edge from the dog, and the vertical slot 40 in plate 10 is for the free travel of lever 17.

The operation of the device has been so fully described in connection with the detailed description of its parts, that further explanation is deemed unnecessary.

Vhile I have here shown the best embodiment of my invention now known to me it is obvious that the mechanism may be varied in many ways without departing from the spirit of my invention.

I therefore do not desire to be bound unduly to the means here shown and described nor any more than is required by the appended claims, and what I claim is 1. In a pencil lead-vending machine, a vertical plate, a hopper having a discharge opening next to the plate toward which it slopes, a plunger-plate reciprocating vertically through the discharge opening to lift a lead to the top of the first plate, and pressure means to discharge the lead from the plunger-plate.

2. In a pencil lead-vending machine, a vertical plate, a hopper having a discharge opening next to the plate toward which it slopes, a plunger-plate reciprocating vertically through the discharge opening to lift a lead to the top of the first plate, and

spring means to discharge the lead from the plunger-plate across the top of the first plate.

3. In a pencil lead-vending machine, a vertical plate, a hopper having a discharge opening next to the plate toward which it slopes, a plunger-plate reciprocating through the discharge opening to lift a lead and discharge it over the top of the plate, the upper end of said plunger-plate being beveled toward the vertical plate to form a lead holding receptacle and spring means to dis--' charge the lead from the plunger-plate.

Signed at Indianapolis, Indiana, this the 5th day of July, 1923.

CHESTER E. SMELSER.
