T. Mother., and .a resident of El in, in the count of Kane and State of Illinois, have inven ed certainnew und useful Improvements in Coin-Controlled Pencil-Vending Machines; and I do herefollowiiig is a full, clear, und exact description thereof, reference being had to the accompanying drawin and to the characters of reference marke thereon, which forni a part of this specification.

This invention relates to improvements in coin controlled vendin machines for vending lead pencils and li e elongated articles, and the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

Among the objects is to provide an exceedingly simple machine for the .purpose which is made of few parts; which requireslittle or no expensive machining in its con# struction; which is strong and urable, and which is certain in its operation to4 deliver a single pencil in each operation of the machine.

In the drawings:-Fi re 1 is a partial front elevation and artial vertical section of my improved mac ine. Fig. 2 is a side elevation thereof with one side wall removed, showing the top wall in. section. Fig. 3 is a vertical section o'n line 8`8 of Fig. 1. Fig. 4 is a detail of the coin controlled inechiinism in a position changed from that shown in Fig. 2. Fig. 5 is a perspective view of a rocking sector shaped member constitilting art of the coin cont-rolled mechanis'm. `i 6 is a erspective view of a dog to normal y lock t and the dispensin 7 is a detail of t e coin controlled mechanism. Fig. 8 is a diagrammatic view illustrating another position of the ratchet and pawl mechanism for preventing retraction of the dispensing member during its operation of dispensing a pencil. The frame of the machine is in the form of a cast' metal casing, it comprises the fr'ont and rear walls 10 and 11 respectively, the end wall 12 and the end wal or plate 13 which extends between theffront and rear walls and terminates short of the bottom wall. The members of the frame referred to may and preferbly will, constitute,an integral casting, an inclose a chiimber 15 to receive the pencils or other articles tc be e sector shaped member' memberstationar Fig.` pocket 'of t e coin" vended. The .bottom of said chamber comrises themembers 16, 17 which are made Integral with, and incline inwardly and downwardly toward eachl other from, the 'frontaiid rear walls of the casing to conli-ititute it hop er bottom to direct the pencils tov the lon iudinally arranged dispensing openingl between the adyaceiit edges ol said members 10, 17, through which the encils drop one at a time on the dispensing member below, as will hereinafter ap- Ipear.l In order to properly adjust the width of the dispensin opening between the hop per bUttOm mem ers 16 and 17 t0 correspond with the diameter of the pencils to be vended, one of said bottom members (the member 16, as herein showing may be provided with: the detachably a xed plate 19, having a forwardly and downwardly extending cylindric'ally curved flange 20.

The' casing shown comprises, in addition `t0 the; parts described', the separably formed bottom wall 21, the top wall 22 and an end wall 28, which are fixedly attached to the inte' r'al portion of' the frame, and some of whic", in practice, 'are removable to perfmit access, to the interior' of the casing' and the money bok therein.

The frontwall of the casing is provided with a deliver' opening' 24, having at the bottom' thereo a floor or flange 25, upon which the pencils are delivered by the dispensing member, in position to be readily removed by the hand. The pencils drop one bly one through'the dispensing opening in 't e hopper bottom of the pencil chamber u n 'a' rocking dispensing' member 27, hereinshown as comprisin a shell of approxiimatel semi-cylindrc orm.` Said shell provi ed at'its apex with a longitudinal groove 28 of a size to receive a pencil, said groove being depressed at its ends 29 for a purpose hereinafter described. The said displ nsing member is fixed to and rotates wit a rock shaft 30, that is mounted at itsl ends in suitable bearings in the casing and extends at one end beyond the' end wall 12 of the casing to receive a crank 31 by which to rock said shaft and dispensing member. The dispensing member is mounted on a shaft through the medium of the arms] 82 through which the shaft extendsaie ima being non-mamey fixed i0 sind arms, as by means of the pins 38 shown. `The dispensing member is normally main tained' with its pencil receiving' groeve llli nppermost'by means of a"volntcspring 85 eoi ed about. the rock shaft with one `end attached to a collar 80 fixed to saidv shaft, and with its other end fixed at 87 to the rear wall of the easin The said-spring nets ou tlte shaft in a t ircction' to hold the era'nktil against a` fixed stop 89 onuthe end ot' the casing, nml to maintain the displeasing member in its normal position. hen the crank is swung toward thefront of the niaehine the dispensing member is rocked forwardly, against the action of the lspring 35, and carries the pencil resting in tie groove of said member between same and tlte tlange orapron 20. When tbe pencil atsses the lower margin of said tlan e 20 it is free to drop on the floor 25 at t e delivery opening 24 in moved by the and. i hen the crank is released the spring 85 restores the parts and when the dis ensin member groove reaches the u ip`er sit e of tie member another peneil fa ls into the same, to be dispensed in the next operation of the machine.

The rot-.king dis ieusin member is locked in its normal posi ion siown in Fig. b means of u min-controlled mechanism wliic i is made as follows: 42 designates, as n whole, a sector sha cd arm which is nonrotativcly fixed to t e end of the shaft 80 justl outside of the plate 13, as b vmeans of a set screw 43 which extends t rough the hub 44 of the arm and impingcs upon said shaft. The upper side or ed e of said arm is curved concentrically to tie axis of the crank shaft` Said sector shaped arm is provided with a pocket 45 to receive a coin from the coin chtite above the same as indicated in Figs. 2 and 4, the pocket being open at its top and front ed e of the arm. The rear side of the coin poc et is closed tn constitute a contact surface to engage with the coin, as the sector is swun forwardly. as indicated in Fig. 4, and the ower wall of the pocket upon which the coin dro s is formed by the curved surface 47. As ierein shown, and preferably, the coin pocket is formed between the main body of the sector shaped arm 42 and a sector shaped plate 48 that is applied to the inner side of the arm and is attached thereto by the screws 40, `as shown in Fi 1. When so formed the coin engaging sur aces 46 may be formed on a thickened part or shoulder 46'l of the plate 48, as shown in Fig. 7, and the bottom of the slot may be formed on the hub 44 at the inner side of the arm 42. In

this way the device may be made of two plain castings which require no machining to form the pocket 45.

The coin chute as herein shown comprises the rearwardly and downwardlvv inclined ortlon 50, the month 51 ot whle opens on he frontl wall of the easing and the downwardly extending portion which ls con- 'the n'lm. Tite said horizontal and upripht .portions of the slot are formed as sha1 t ositiOn t0 be rnected at. its upper end wit-h the. portion o0. The lower emi of the upright portion of the ehn'tevis directed obliquely downwardly toward thepoeket 45, and is eurved at. its ex` tremo lower ond to correspond to tite curvature of the up ier sida of the sector shaped arm 42, so tlm tho relativo position of the sector shaped nrni and the eoin slot is' not changed during the swinging movement ot grooves in a thickened portion 53 of the wall or plate 13 and the outer side of said slot comprises the plates 54, 55 which are 'n plied over tho grooved portions of the enst v'p ate or wall and are attached thereto by screws 56.

The arm 42 and thc dispensing member 27 are normally held from rocking forlwardly to dispense a pencil bv meansI of a .swingm locking do 5i) having a huh (to by w ic i it is iivotet to n piti or sind (il extending froin t ie plate or wall 18. Said dog comprises a flat portion (l2, adapted to lit` over the coin pocket 45, and a lnterallv yturned portion (t3 having a notched tooth which extends into au opentng ott ot" n curved flange 07 that extends laterally and outwardly from the arm 42 and is curved lconcentrically to the shaft 30. Said notched tooth of the dog lies in the path of the edge 68 of said lian e at. thc rear of the opening 06 therein. Tie dog 50 is held pressed toward the sector shaped arm 42 by means ol' a volute s ring 69 which is coiled about the hub o said dog, with one. end fixed by tbe screw 70 to n fixed portion of the easing. and with the other end engaging over the dog between its free end and its pivot mounting.

With this construction itl will be observed `that. when no coin is in tite. pocket nml the dispensing member and the sector shaped arm 42 are swung forwardly said parts will be arrested by enga ement of said dog, with tbc edge 68 of the filling@ (i7 so as to prevent the dispensin member being swung forwardly a sn cient distance to dispense n pencil from the machine. When n coin ot' proper diameter is in the pocket, however`v as indicated by the dotted lines in Fig. 2. said coin extends above the level of the heel 72 of the dog, so that when the arm li2 is swung forwardly to en age the coin with the rear wall 46 of the coin pocket, said coin is forced forwardly, and acts to qneldtl raise the locking dog 50 to swing its notched tooth out of the path of the flange (i7, and t0 thereby ermit the dispensing member to be swung orwardly a sufficient distance to dispense a pencil and to deliver the coin through the open side of the pocketl into the money box below (not shown) placed in the lower part of the easing. When the crank 81 is released the parts are restored llt) llfi

through the slot into the money box below 35, should the crank 31 be released, after the engagement of the rear ed e of the extenin Fig. 7,

to their normal positions by the spring 35 and are arrested in said normal positions by engagement of the crank 31, with the stop Sil; the notched tooth of the dog dropping into the opening 66, as the sector'shaped arm lf2 swings backwardly, in position to prevent further operation of the device until another coin is inserted into the machine.

The flange 67 of the arm is provided with a rearwardly extending portion 73. concentric with the axis of the shaft 30, which curved portion serves to close the 'lower end of the coin slot when the arm and the dispensing member are swung forwardly, and to thereby prevent a coin being dropped at a time when the machine is in operation.v The coin engaging surface 46 terminates at its inner end in a rearwardly inclinedtportion 69 which operates, when mbre than one coin is presented to the pocket at one time, to force the last or rearward coin back into the chute when the dispensing member is rocked forwardly so-as to prevent the coins locking the machine from operation.

In order to prevent thedispensing member returning, under the action of the spring coin has been delivered into the coi-n box and before the pencil has been dispensed, I may provide the flange 67 of the arm 42 with a series of ratchet teeth 75, formed on the lateral extension 76 of the flange, said ratchet teeth to be engaged during the dis ensing movement of the parts by the loc ing paw] 77 which is pivoted at 78 to the outer wall plate 55 of the lower portion of the coin slot. The said pawl 77 is pivoted between its ends, with its biting end normallyA in the path of the ratchet teeth 75 and the extension 76 which carries the teeth, as shown in Fig. 2, and is normally held in position by a spring 79 that is attached at one end to the tail of the pawl and its other end to a rpin 80 which is fixed in the outer wall et' rthe plate 55 of the coin slot. When the sector and the dispensing member are swunaY forwardly therefore, the ratchet teeth more beneath and in contact with the pawl, so that after the coin drops out. of the coin pocket into the money bony below, the dispensing member can not be restored until after it has been swung forwardly far enough to deliver a pencil, and far enough for thel ratchet extension 76- to pass the pawl ,tg permitpthe latter to fall behind said eiitension,` Upon the return movement of the dispensing member, after the complete operation of dispensing a pencil, the pawl is turned backwardly or reversed from the position shown in Fig. 2 by sion 76 with said-A paw, as indicated l and in. this position the ratchet teeth 75 are free to ride undri the biting end of the pawl. .After the forward edge of the ratchet extension 76 passes from under the pawl 77 during the restoring movement of the dispensing member the spring 79 acts on said pawl to restore it into the position shown in Fig. 2, or in position to again lockingly engage the ratchet teeth when the dispensing member 'is again swung forwardly.

Preferably, and as herein shown, that por? tion of the upper surface of the semi-cylindric dispensing member in rear of the pen-r cil slot of said member is formed on its upper surface to provide a series of longitudi nal corrugat-ions 87 which, when the di'spensin member is swung forwardly, en gage t e lowermost pencils in the pencil chamber in a manner to juggle or tumble the same upon each other and thus rearrange them in case they should become disarranged or should lie in crosswisev relation to each other. 1n this manner the pencils may be maintained in such position that when the dispensing member is restored to normal position one of the pencils will always be free to drop into the dispensing groove thereof.

The provision of the curved shield or flange 20, carried by the forwardmost member of the hopper bottom, prevents the de livery of a pencil to the delivery space oropening until after the dispensing member has been rocked a suicient angular distance to release the coin from the coin pocket. Said flange also permits the dispensing member to have some freedom of angular movement, as indicated in Fig. 2, without liability of a pencil being dispensed when no coin is in the coin pocket.

In order to prevent a magnetizable check from being inserted into the machine to operate it, I `may arrange a magnet 82 at the angle of the coin slot where the coin.

a ma netizable check reaches this point it.

is de ected outwa dly toward the lip 84 and is diverted from t e coin slot and falls into the coin box beneath without operatin the machine. lVhen a magnet is so user? the plates 54 and 55 will be made of brass or like the non-magnetizable material. It is advantageous to provide an indirect coin slot when such a deflecting magnet' is em" ployed in the manner shown, inasmuch as pencils in the chamber may be observed through the glass front-90. When a pencil to be dispensed a coin is dropped through lthe coin slot or chute into the coin pocket 45 of the sector shaped locking arm 42 and the crank 31 is pulled .forwardly to swing the dispensing member and said locking arm forwardly. As the locking arm moves forwardly the rear surface 46 of the coin pocket engages the coin and carries the same forwardly with the arm, andthe said coin raises I the dog 59 with its tooth 63 out of the path of 2 i mfr into position to I locking dog provided with a toot the iiange 67 so as to permit the dis ensing member and locking arm to mo t roughout the ent-ire dispensing movement of said member, or approximately 90 degrees. This movement of the dispensing member may be limited by engagement of the crank 31 with a stop 91 on the end Wall of the machine. As the locking arm moves forwardly the ratchet teeth 75 ride beneath and are engaged with the pawl 77 to prevent accidental retraction of the vending member in case the crank should be released before said member has completed its vending movement. The pencil carried forwardly in the grooved dispensing member is released as the groove of the dispensing member passes the edge of the flange 20A and the pencil drops on the flange 25 at the delivery open ing 24. Lugs 92 at the ends of said {iange prevent the pencils from rolling out through the delivery opening, while permitting w.iter, which may fall into the delivery opening, to be drained therefrom. When the crank 3i is released the spring 35 restores the parts to their normal position so to bring the groove of the dispensing lreceive another pencil, to be dispensed inl the succeeding operation of the machine.
