In order to close the coin slotv9' when thev n machine is empty, we providey a platel45pivotallyA mounted at its lower endy and Ahaving connected atits upper end one end of a rod 46, the opposite end oi" which as seen in Figure 5 is connected to one end ont` an elbow lever 47 to which is also connected a rod 48 which is connected with a rock 4shaft 49 mounted on a cover plate 50.` Apivoted ylever 5l is connected to the other end of the rock shatt 49'byfmeans of a pin and slot connection and the parts are so weighted that in the position y-seen in Figur-e 5 the coinslot can be closed bythe plate .45* and the'lower'end of thelever 51 will be'roolred inwardly towards a package or article to be vended 52 but suohinward movement will bev limited by the lastpacliage in the last compartment; so'that whenv the door '2 is closed the coin slot 9 will be uncovered by the plate 45 until th-e Vlast package has been vended, as will hereinafter be explained.v

leneath the coin retainer is positioned the moneyblox 53. rlhe'casing l has secured in its bottom portion in any desired manner a plate one end of which is downwardly deflected, as at 55, to form a wall of the Joclet- 8. Jfibovethis plate 54 are secured the angles 56V the laterally extending lower flanges of which `form supports and guides for the articles to beivended. The laterally extending flanges of the angles 56 are cut away, as indicated at 57, Ysee Figurer', so that when the articles are above the pocketsY 8 Aand released Ifrom the article carrier they will drop by gravity into such poclrets'8.

ln proximity to the pockets 8 the Vvertically extendingl flanges ot `the angles v56 are provided wi'th the *slotsY 58, see Figure 7 andV also f5 and 8.VV v

rlhe rear angle A56, see Figure 2, has al bar securedV tothe rear wall of the casing` Abelow it so as to form a slot 69 and in a similar manner the door 2. and the cover plate 5 'form avslot 6l'said'slot"servingas rguides for the article removingfmember 62,

see more particularly Figures 3 and 4.` rEhe article removijn member 62 is provided with bottom plate 63 to which Vis secureda bar 64 slid'able in-the slotr 6.0 and also aber 65 slidable in the slot Y61.V Thisib'ar 65 is provided with a grasping portion 66 by the hey 6'? which travels ina leyway 68 carried by the front plate 5, see Figure 2.A

Vmear-is of wh'iehfit is manipulate/denti Valso'` 130V The door" 2 is provided with an *inwardlyA extending' bottom flange 9vwhich`co`ntributes to form a guide for the article removing member. The bar l has secured to it in any desired manner a'vertically disposed cam plate having projecting from its forward' edge a cam 71 provided with a forwardly and inwardly extending cam surface 72. Above this cam 71 is pivoted at'73 a stop 74C in' the form of an arm having Va hook 75 at vits forward end and provided with a spring 76 one end' of which is connected to the stop 74 as seen in Figure et while its opposite end'is connected to a fixed point, for example, a screw 77.

The front face of the cam plateYO is pro- 1 vided with a cam face '.7 8 which inclines forwardly and upwardly. The cam plate 7 0 carries abovethe cam face` 78 a cam bloclr 79, the top face yof which inclines forwardly and' downwardly, as azt- 80, andy rearward.- ly and downwardly, as at 81. lts under face -in'clines forward and upwardly, as indicated at 82, and rearwardly andy upwardly, as indicated at 88, so that the cam block 7 9 has substantially a diamond contour. The cam plate 70 at its front upper end is provided with the upwardly extending lug 8d, the top face of which inclines forwardly and downwardly, seeV more particularly Figures 31. and 14.. 'The bottoni plate 68 of the article removing member has fulcrumed on it at the clamping levers 86, see morel particularly Figures 4, 7 and 8'.. The rear ends of these'. levers are ldeflected outwardly and carryv on their inner face the studs 87 which position a spring 88,. the tendency of which 'is to. move towards each other the forward ends of the clamping levers 86, the forward portions off which arerearwardly and .inwardly deflected toform the jaws 89, the free edges of which vare preferably serrated; The clamping levers 86 are angularly deflected?, as at 90, in order to conform to the. shape of the package. or article which vis to. be vended and as the package ill-ustrated' is substantially rectangular the clamping'levers are clamped to4 form sub-y stantially a right angle..

It will be' understood from Figure 7 that the forward portions 91, are bentlaterally so that during their forwardmovement they will ride against the upwardly extending` flanges of the angle 5,6 which causes the clamping or grippingportions of the lever tomove towards each other and be retained' posed have been The cam face on thelugSl, co-operates f of the lever 97 has a pin and slot con-V nection Vat 102 with aroclr shaft- 103 mount.-

The clamping levers 86 are released by means of a lil-shaped releasing member 105 secured in any desired manner in fixed position vin the path of the outward- V ig endg of the clamping levers when fcle .removing mem-ber reaches its rearward position. rEhe releasing with. the spaced arms which preferably diivergetowards their free ends. The cam face 72 of the cam ?1 is adaptedl to co-opcrate with the cam face 106 and thecam 10'?, see more particularly Figures 5, 6 and 7. lVe will nent describe the cabinet portion of the machine in which the articles to be vended are sold. As will be understood by reference to Figures 2 and 5, tlie'rear'wal'l 108l of the cabinet has connected with it a bar 109 to which is secured a rear plate 110 to which are connected in anyV desired man- 4ner the rear ends ofthe partitions 111. The

top of these partitions are secured in anyy downward movement of the rock shaft `103,l see Figure 6. 'The lowerv ends ofthe partitions 111 are simply cut away, as at 117, Isee 'Figure 2, 118 designates the packages or articles which are to be vended which'are su.-

perimposed upon each other intheir respec-V tive article receiving chamber 115.v l y The operation of ourncvel vending machine will now be vapparent to those skilled in this art and is asfollows:- p Assuming nowY thatv all the compartments 115 in whic-h the articles are superimiilled and vthat the parts of the coin mechanism are'in their-initial or neutral position; thatthe article carrier is in the position it assumes` when at the' reary end of the stroke and that4 the door is locked, the machine is ready for operation.` The'intending purchaser glaces' a. check or coin of the proper denomination inthe coin rlhis plate 1118 is'pro-y nember 105 is v.provided slot 9 and the coin will pass through the coin chute 10 and be received in the coin retainer 16 and will come to reston the laterally deflected larm 40 ofthe member 39. Ait this Vtime the bar 34 is in its raised position and this bar V34, as will be understood by reference to Figurell, is connected to the lever y 33 which in turn is connected to the member 39 .which carries the .arm 40 on which the coin is resting. the parts pist described being retained in set position by means of the spring 43 and the bracket 41 interlocking with the walls of the slot 42 of the member 39. rhel purchaser now takeshold of the handle port-ion 66 of the article removing j member and moves it towards the left. Y The roller 32 carried by the bar 29 is .at

- this time in its raised position by means of i the spring 26.

As the article carrier is moved forwardly, the roller 32 is in the path of the cam face 32 so that such forward movement-of the article removing;L member 62V causes the bar 29 to be drawn downwardly, see 4inoi'e particularly Figures 13 and 3.

As the bar 29 moves downwardly, it rocks the lever on its fulcrum thereby causing' the cani shapedA portion 24 to move'into the slot 123 and engage the coin or check which is in the coin retainer and this pressure on the check or coin causes the latter to move downwardly sufficiently Vfor the upper arm of th'ebracket 41 to be released from the Vrecess 42 in the arm 39 whereupon the Vspring` 43 will draw'the arm 39 rearwardly and permit the coin to drop from the coin retainer 16 into'tlie money boX 53, see Figure 5. This rearward movement of the member 39 rocks the lever 33 on its fulcrum therebyY causing` the bar 34 to move downwardly andthe lug or cam 37 will be received Ain. the'recess33 of the guide block 31, so that 4the lug 37 isiiowin the'position seen in Figure 9'. Y Y Y As the article reinovingmember moves forwardly in the manner just described, the lug 34,A see Figuresc13 and 14, rides under the stop Ymember 99 and as it passes by the .cam` face 100 the arm97 will berocked on its fulcrum 98Ythereby rocking the rock shaft 'Y :to

.theY lever 97 willV drop into its -tion seen in Figure 14 so that 1 39 'Mare moved towards Jfianges of the anp-fles shoulder 101 normal posiafter the article removing` member has moved forwardly it rcannot beV returned to its starting` position unless an article has been taken up and is being Ycarried bythe article removing mem- 103 and -as'it'passes thestop ber on its return movement. the article removing member moves forwardly, the jaws each other by their engagement with the upwardly extending The article retrieving` member is moved l forwardly until Vthe clainpinr jaws grip the Y -l'owermost article in the first c iamber which `contain `s anf-article and as the spring 33 is provided, see kFigure 7, the clamping jaws Ywill rresilientlyy engage and grip4 opposite ends of an article. Y 1

rlhe operator now moves the article receiving member rearwardly and vas the article comes in the path of the hooks or fingers 104.

the shaft 103 will be rocked so that the cam which they have been carrying and the arf ticle will fall into the pocket Sinto a position accessible to the purchaser.k The last article in the last compartment presses against the cam 107 so that its inward movement is limited and the coin slot is uncovered by the plate 45. l/Vhen the article removing' member is advancedk to vendqtlie last article, the cam surface 72 moves thev cam 107 away from suoli article so -that ythe clamping jaws 89 can take hold of the last article. When the last article is vended the cam 107 is free to swing inwardlyso that the coinV slot will ybe closed byr the plate 45. It will be seen that. the article removing` member after once being started in its forward movement after its release by the coin `mechanism cannot be again returned Vto its starting position unlessY it has been moved sufficiently in a forward `direction vfoithe clamping'jaws to pickup an article. Y n

lf the article removing member on .its

return movement doesnot carry Yan article then the cam lever 97 will be in its lowermost position so that the stop member 101 is inthe path of the lug 34, seefonexainple Figure 14.V After the coin .mechanism has Y been unlocked, it is automatic-ally reset so that on the lreturn movement of the article removing,` member the .lug V37 on lthe bar 34 is in the path of the hook ofthe stop 74' and this hook -is provided withv a cam face so that it will ride over the lugv 37 being Ymoved upwardly againstthe tension of the spring 7 6 andit will thenpdropinto the po'- sition seen in .Figure 3 so Vthat it will be impossible to move thel article removing member forwardly to vobtain'an article yun'- less another check or coin, has been: deposited in the coin mechanism, The stopf99 acts as a safety stop so thatpif a coin has r'been' deposited in the machine-the article removing` member cannot be moved rearwardly to its startino; position unless it has suiiiciently to clamp an article. ,l

first imparted to it its full Vfoivard stroke f VlThe coinY mechanism-is yreleased by the cainface V82 during the forward movementv 'ot thearticle removing member as this draws downwardly the bar 29,. This Vas before explained -eiiects the downward movement 'ol' ythe bar Se so that as the article removing member moves forwardly. after the colin mechanism has been` released the rolle-r 36 on. thebar 84 will engage the cam race 8O ofthe cam block TQWthei-eby causing ,the bar Salto move upwardly thus rocking the lever 33 and moving the member 3,9 forwardly suthciently to causev the walls ofthe recess l2 to interlock with the upper arm `ot the bracket 41 so that, the laterally extending arm 40 will close the bottom of the coin retainer 1.6 and the coin mechanism is reset ready for the next operation.

The bottom 'of the slot V18 of the coin retainer 16 is normally closed by the lip 21 and whenthe coin mechanism is in set positionv it is moved outwardly as will be understood by reference toligure 12. 'When the bar 29 is moved downwardly to rock thel lever 25 the lever 28 isiroclredl to` eliecft the openingl of the pivoted sidell. of the coin chute'10 so that any article'ietained in the `coin chute will pass V.through the return chute la and will drop into the pocket 8 into a position accessible to the intending purchaser'.

It will now be apparent that we have devised anew and useful vending machine which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while we have, in the present instance,

shown and described ar preferred embodiment thereof which will give in practice .satisfactory and reliable results, it is to be understood that such embodiment is susceptible of modiiication in various particulars without departing from the spirit or scope of the invention or sacrificing any ot its ad-V vantages. v
