WILLARD WALDRON, OF BAY CITY, MICI-IIGAN.

PENCIL-VENDNG MACHINE.

Application filed January 2, 1923.

To all whom it may camera:

Be it known that I, lVILLARD VVALDRON, a citizen or" the United States of America, and a resident of Bay City, in the County ot Bay and State ot Michigan, have invented certain new and useful Improvements n PeneiLVendine l lachines, of which the tollowing is a specitication.

cThis invention relates to Vending maehines, and particularly to a machine tor automatically ejecting pencils and the like A still further object is to provide means `whereby washers, slugs, and other ob ects will be automatically ejected without operating the pencil ejecting mechanism.

The above and other objeets will appear as the speeification progresses, reference being had to the accompanymg drawmgs n which like reference numerals indicate like parts through the several Views thereof.

In the drawings Fig; l is a front View of my mprored Vending machine.

Fig. 2 is a side View. the walls of the case being broken away and shown n section Fig. 3 is a front View of the Operat ng mechanism, the ease being removed.

.t is a top plan View ot the Operating mechanism removed from thecase.

Fig. 5 is a side View of the pencil ejecting means, the mechanism being shown in two different positions, the full lines showing the meehanism locked, and the dotted lines llustrating it in position when the pencil is ejected.

Fig. 6 is a fragmentary View of the com and pencil ejeeting 1necl`1anism, tl ie parts being 'shown in two different positions.

F ig. 7 is an enlarged front ,view of one of the pencil containers or cradles.

Fig'. 8 is a transverse cross sectional View taken on the line.8-8 of Fig. 7; and

Fig. 9 is a -fragmentary View illustrating` an'alternate Construction for the pencil stor age or hopper.

Seria] No. e1o,194.

Referring` now particularly to the drawings in which I have shown the preferred embodiment of my invention, the numeral 1 indicates the ease in which the Operating mechanism is housed. This case is provided with a removable back 23 which is adapted to be locked in position by means of a lock and key attachment (not shown), an elongzated opening: 3 is formed in the front of the ease and through which the pencils are adapted to be ejected, falling into a trough 01' receptacle l tormed integral with the case. A coin slot 5 is prcvided for the insertion of money, and a dial (i is Secured to the front of the case and is provided with spaccd apart openings 7 in the face thereo'f, 'each of these openings being numbered :tor a purpose to be presently described.

A crank 8 is mounted on a lransversally disposed shaft 9, a spring actuated plunger 10 being mounted on the crank and is adapted to engage one of the openings in the dial. The kinds and grades ot peneils are printed on a slip posted or otherwise secured in the glass cover-ed opening ll in the front ot the ease, and each particular brand is numbered to correspond to the indicia on the dial, as an example, it' a Customer wishes to purchase a No. 2 American Velvet pencil, he grasps the knob ll on the end of the plunger 10, pulls it OUtWfll'dly, thereby disengaging it from the opening in which it is seated, rotates the crank to the No. 2 as indicated on the dial, releases the knob, and the end ot the plunger eng-Liges the opening which is corres ondingly n'arked. The mechanism is then set to eject this particular brand ot pencil; it is merely necessary to in sort the proper coin, grasp the lmob 12 forc ing it downwardl which will automatically eject the pencil.

The merhanism on the interier of the case is arranzed as a unit, and comprises a pair of upright side plates or members 13 seeurely tastened to the base plate 14; these are braced by means of the rod 15. A pluralitv of lonzitudinally disposed sha't'ts lt' are journaled in these side members` the central portion thereot being machined to form a seat or cradle for the pencil which is adapted to be nested thei-ein, the ends of the shaft being' solid. Vertically extending channel members 17 are seem-ed to the side plates in direct Vertical alinement with the ;said shats, and are so spaced so that the ends of the .pencils 18 rest in the chan- Outu 'ardlvextendingr arms 24 are tormed nels, the pencils are then placed one upon the other in superimposed relation, and this provides a very compact supply with a'large capacity.

The shatts 16 extend through the side plates and cranks 19 are mounted on the one end thereort, each shaft and its actuating mechanism is identically slike, and I shall theretore describe but one unit; a coiled spring 20 is carried on the opposite end ot the shaft, the one end being' anchored to the shatt proper and the opposite end being anchored to the upri rht plate; this spring is wound to provide a' tension on the shutt` a stop 21 being: provided on the opposite end and is normally engap ed by the crank 19 when the shutt is stationa'y, and the spring is wound to normally force the crank against the stop.

I shall describe the pencil ejeetine mechanisin in detail, and this comprises the transversally disposed shaft 9 whichis mounted in the bracket 22 secured to the side member 13 and on which the crank member 8 is mounted.

A spider 23 is mounted on this shait 9 and is longitudinallv slidable thereon being prevent-ed from rotation on the sha'ttbv means cit a slot and iteather kev (not shown) but which will however admit of thi longitudinal movement of the spider on the shaft.

integral with the spider 2-3 in spaced relation, and collars 25 and 26 are also formed thereon. A fiat circular disk 27 is securely riveted to the, bracket 22; openings 28 are formed therein in spaced relation, a coiled spring 29 being nterposed between the said disk and the collar 26 as shown. A transversally projecting pin 30 is also fixed on one of the spider arms, and is adapted to enone of the openings in the disk 27 when the mechanism is in correct Operating 'positioL an arm 31 being pivotally mounted on the pin 32 which is set in the side ot the plate member 13, the end being forked to straddle the hub ot the spider and engage the collar 25 thereon; this arm is slotted te receive the link 33, which 'is pvotally connectedto thelever 34 at the point 35. a pin 36 being mounted in the opposite end as shown. The lever 34 is pivoted to a bracket 37 which is securely riveted to the side plate, the end extending through the front of the case, and having the knob 12 detachably mounted thereon, a coiled spring 38 being anchored to the link and the lever for forcing the lever 34 back to itsoriginal position.

Normallv all the cranks on the shafts are in upright vertical position as shown in Fig. 2 of the drawings, and when the mecha'nism is setin correct Operating position, one of the spider arms 24 will be in horizontal po sition projecting inwardly towards the side plate, and When the knob 12 is forced downwardly, the member 31 will slide the spider on the shai't 9 compressing the spring 29; the spider arm will engage the crank 19 on the end 01 the longitudinal sha-ft 16 which is toi-med as clearly shown in Figs. 7 and 8 ot' the drawings, rocking it in its bearings so that the pencil cradled therein will be discharged or fall theretrom, and when the knob 12 is released the spring 29 will force the spider and lever 31 back to their original positions, and the coileo' spring 20 on the end of the longitudinal shaft will automatically rock this shaft back to its original position against the stop 21 and another pencil will feed down and be c'adled therein.

An inclincd plate 39 is located directly heneath the pencil storage or channels, so that when the pencil is ejected it will roll by gra ity through the slot in the case into the trough on the front thereot, from which itis taken by the purchaser.

It will be obvious that the mechanisn'i cannot be operated unless it is properly set, as the end ot' the pin will contact with the solid surface ot the disk 27 and prevent the knob 12 being forced downwardly, thereby insnrinz correct n'anipulation( The spring 38 will naturall return the knob 12 to its proper' position.

i i 'hen the machine is set and a coin ot the proper value is inserted in the opening' 5 provided in the case, it drops into an inclined runway or trough 40, thcnce roll ing into the passage 41 provided in the leg 42 and lodging in the 'position as clearly shown in Fig. 6, the larger portion of the con being contained in a pocket 43 formed in the member 44 which is pivotally mountcd on the support or bracket 45 rigidly secured to the side plate, a coiled spring 46 being anchored to the stationary leg 42 and to the pivoted member 44; the lever 34 on which the knob 12 is mounted is provided with a knite edge on its underside and eX- tends between the members 42 and 44 above the coin, and this pivoted leg 44 is provided with a jaw or slightly nclined horizontal surface 47 directly beneath the lever,

and when attem tin to o )erate the machine without first inserting the coin, this lever 34 will engage the ja w 47 and prevent further downward movement thereot, but when the proper coin has been inserted, the lever Will engage the coin to one side of the vertical center thereof, and continued downward pressure will force the member 44 outwardly as shown in dotted lines in Fig. 6, this in turn forces the lever 31 forwardly, the pin 30 engaging one of the openings in the disk 27, and the arm 24 on the spider engagng the crank 19 on the end of the shatt 16, thereby rocking the said shaft sutticiently to cause the pencil to fall therefrom.

A conventional magnet 48 is mounted lGO alternate form of pencil storage, theupper end being enlarged in one direction as shown at 51 and provides a much larger Capacity; in this construction the pencils l'eedin an exactly similar manner and do not hang or clog therein.

From the foregoing description itwill he ohvions that I have perfected a practical, simple and efiicient pencil Vending machine,

which is positive in its operation, and very.

economical to build.
