T e coin slots` 66 and 76, the runway 69, the bar 73 and the guide 7.9 are provided for the operation of the machine with a quarter vof a .dollar,'while the coin Slots 67 and 77, the runway 70, bar 74 and guide 80 are prt vided for the operation of the machine with a half of`a dollar. The coin slots 68 and 78,

the runway 71, bar 75 and guide 81 'are prof vided for the opera-tion 'of the machine with a dollar.v The guides 79, and 81 have apfertures 82 and 83 provided therein, the ap ertures 82 being ka trifle smaller. than the coins used in the respective slots, vwhile the apertures 83 are a trifle larger. The object of this arrangement is to prevent the operation of the machine with undersized coins or slugs. Any undersized coins or slugs'that may he inserted into one of' the

com slots

66, 67 and 68 are guided into the respective coin slot of one of the bars 73,74 and 75 where they fall through the aperture 82 into the coin box yfincorpqrated '1n the housing 1, while the correct coin-will remain in the y coin slot into which it had been guided until it is pushedover the aperture 83 where it.

`will fall'intovthe coin'groove 50 of the trip -lever located directly underneath the said aperture 83. 4 Buttons 84 are secured to the bars 73, 74 and 75; the said buttons 84 being marked to show the denomination rof the coin with which the respective bars operate` Springs 85- are secured tothe bars 7 3, 7 4. ,and 75 andto the runways 69, 70 and 7'1 to provide means for retaining the normal positi'n ot' the bars 7 3, 74 and 75 after the said bars have been operated.

In operation, the valve 57 in the' primary gasoline line 55 is closed. The governor' 27 which govcrnsthe speed of the spring 1 motor 5, is regulated according to the rise and fall ofthe price of gasoline by i'neaus of theregulatingdeviee 28 which operatesas follows: The screw 29 is turned until the indicator 35 of :the guide collar'32 pdints to the current price of the liquid heilig dispensed, as forinstance, eighteen, asshown on the gauge plate 34 in Figure 5. In thus setting the' guide collar 32, the governor 27is either expanded or contracted hy means of the lshifting arxii 33 which engages' the `governor dise Q5` thus controlling,r the speed ol' the niotor 5 in the n'ell known manner. ln order to operate the loall and socket type valve 5S) a eoin is inserted into one ot the eoin slots (iti, 6T and G8. A eoin of the t\vent),live eent. denomination would he in-4 serted into the eoin slot 66 and pass through the runivav ($9 into the coin slot 7.6 oi the har T3. The button 8-1 ot the said bar 73 is lpressed forcing the har 7S back until the coin slot (Sti is in line with the aperture 83 ot the guide T9. whereupon the coin will drop into the vcoin `njroove ot the trip lever flo, causing' thelsaid lever to overhalanee, thus raising the drum lockinglever it enougrh to permit the arm 42 to enter the gfroove 38 upon the rotation of the measuring drinn liti. The Coin rolls aloner in the eoin` groove 5() until the end ofthe said trip lever 45, ivhere it falls into the coin box 3, As long` as the coin remains in the eoin groove 50 of the trip lever 45, the drinn looking lever 41 will remain in a raised position, thus giving the spring` motor ample time to yget into motion in order to rotate the measuring' drinn 36. The hall and sorltet type valve 59 remains closed until the roller 44 ot' thy arm 4Q- starts aseendv ing the rise loeated in the `groove 3S prior to entering; the shallow portion ot the said Agroove IES. In@aseen-dingl into the shallow portion of theigroove 3S, the roller tat ot -the arin 43 Comes into Contact with the arm n l i 5B ot the valve operatingT lever 52. thus raising' the said arln 53 and turning the'arln 64 ot the eccentric (i2) down. lVhen the arin G4.

ot the eeeentrie 63 is turned down, the said eeeentrio (i3 is turnedrthus opening' the ball and socket type valve 59 and permitting lthe gasoline to pass through the said valve '59 into the regular glass container. The hall and soelet type valve 59 remains open until the arm 42 drops hachr into the groove 37. (foins inserted into the eoin slots GT and ('tw will operate the deviee in the saine inanner'as ahove described except that. the extreme ends ot the levers Lt6 and t7 whieh are slie'htl) int-lined toward the dru'm loeliingI lever tl ivhen raised will eanf-se the said drum loeltin-g lever 4l to slide in linewitli the respective `groove ot the drum 3th relative to the. operated lever. ln order to eut out. the vending machine the valve 57 ot the primary gasoline lille is opened up.
