The coin control mechanism for'mi'ng the subject matter of this application is provided with suitable adjusting means which will be hereinafterzmore fully described. V I

The coin control mechanism operating means comprises a spring retracted handle 9 provided with a suitable grip portion 10 and pivoted at 11 to the side wall of the. recep tacle Disposed adjacent the grip portion of-the handle 9 is a pair of guide members 12, secured to the side wall of the receptacle l,. preferably, by meansof bolts 13 and 13 in spaced relation to each other. The bolts also function as limit stops for the downward and upward movement, of the handle 9. 7

Secured to theinner front wall of th closure 8 are a pair lugs 1d provided with suitable pins 15, whiclipins engage slots 17 on the arm 16 supporting the closure in its two adjusted positions, for either ,lremoving the coins from the receptacle, or for operating suitablemechanism more fully described in my co-pending application filed concur rentlyfherewith, Serial'No. 119,020 for arranging the vending aparatus for proper reception of a new supply of articles'to be vended, The top portion 'of the closure 3 projectsbeyond the rearwall of the'recep-.

tacle,-and is curved downwardly'at 18 to prevent rain or the like from entering the receptacle; Oneof the side walls of the closure is provided withia coin slot 19 which registers .witha coin, slot 20 inthereceptacle 1, for

the reception of any desired number or kinds of; coins for setting the coin control mechanism in position for the actuation of the handle 9, thereby enabling the lever controls which will now bedescribed to beunlocked.

Secured in any suitable manner to an eccentric 11 on the pivot 11, and disposed on the inside of the receptacle, at 22 is a spring retracted operatinglever 23 for operating the coin control mechanism 27 through the agency of the vertical link 25, pivoted at itslower end to the operating lever 23 near Ehe' outer end thereof at 2st, the upper end of which is detachably secured to a headed stud26- carried by thecarriage 33 of the coin control mechanism. The co n control mechanism which will now be described is secured preferably in the upper right front of the receptacle 1 adjacent to coin slots 20 and 19 and to the rear ofa flange formed in the front end of the side wall of the receptacle and desi nated by the numeral-80.

Depending from theoperating lever 23 at substantially the center thereof is a link 94 which is connected with a vending mechanism which is'fully described in my co-pe'nding application-- filed the same date as this application and covering a vending machine.

7 By depressing the handle 9 in a downward My vending machine may be operated by i 25, and when coins-are inserted into the slot 19 and20 the. coin control mechanism will operate ina manner which will hereinafter be more fully described. 7 .1

The coin control mechanism is preferably mounted in a base plate 27 formed substantiallychannel shaped in cross sect-ion, one end thereof being bent upwardly at right angle to form aside wall 28. Opposite the side wall 28and arranged in spaced relation thereto is .an angle shaped rack bar supporting member 29 secured to the base plate 27 preferably, by means of screws, andprovided with an overhanging rack 30 provided with a series of flattened rack teeth. Ad-

jacent the two ends of the rack bar-are two .cut'away depressed surfaces 31, one adjacent the lower end of the-rack bar 30, the other being adjacent the upper end thereof. Disposed to the rightand substantially in the center from top to bottom of the upper depression 31 of the rack bar 30 is apin 34L secured in the rack bar 39 and projecting therefrom. A pin 34 issecured to the rack bar 30. in vertical alignment with the pin 3%.

below the same and disposed two teeth above the-lower depressed portion 31 of the rack bar..

. Carried adjacent tothe'upper end of the rack bar suplport 29-is an adjnsting'pin or spring 32w ich may be secured to the rack bar support 29 preferably by a bolt, one

end thereof projecting. laterally with re spect to the rack bar support 29 and having the adjusting pin. 71 which will be more I thoroughly describedin another portion of this specification. The adjustment member 3615 provided with suitable indicating marks. 7

A portion of the periphery of the rotary adjustment member 36'is cut away to form oppositely disposed flattened surfaces 87 and .38 having the suitable indications adjacent my invention the operation of these parts is as follows Assuming the machine to be in normal position as shown inFigs- 1 and,7,-with Eff/10165 to 'be' vended placed in their proper position in the receptacle, a coin or coins are and fastened, to the lug 26 0f the carriage causes the carriage 33 to move downwarda predetermined distance, depending on the numberofcoins inserted, to a point where the lever 49 engages one of the COlIlSfiIld 1s;

caused to ride over the outer faces ofj'as many of 'thecoins as are disposed within thev channel 65, and is therebycaused to swing V in the counter-clockwise I direction on its pivots as best shown in Fig.' 8. The lower end of the lever 49 engages the pin 53 on' the lock lever154and swings the same on its pivot 48 a ainst the tension of the spring 58releasing t e hook endv 60of the lock-lever clear, of the projection 61 oflthe rack bar and permitting the carriage 33 to continue 7 its free andfull stroke downwardly.

Upon downward movement of the car-' riage 33,:if a coin has been inserted in the channel 65, the end 50 of the lever 49 will ride up on the coin, and the lever will be rotatedabout its pivot. This, by engage-.

- "bar'BO. Full down stroke movement of the ment of the portion 52 with the. lug 53 will rotate the lever 54'movin'g the endfiO thereof away from theproje'ction 6l on the'rack carriage 33 is thereby permitted ifthereis a coin or coins in the channel, but if there are no coinspresent theend 5040f the lever.- 49 will enter into the coin channel'through an opening provided therein as particularly] shownin Fig. 9, thus preventing the re-;

7 41 oftheicrescent shaped double 'aotingpawl- 55 wise into the position shownin Fig. 8, with I movalof the end of the lever 54 from the projection 61, as described. Thedouble acting pawl 39 is'in tl1e posi-' tion shown inFig. 7 at the start of'the downward travel of the carriage. As they carriage" moves downward, the pawl tooth engages the first tooth of the rack bar-30 which rocks the pawl and the lever 42 clockthe tooth 41 ratcheting over the teeth of the rack 30 to prevent premature reverse movement ofthe carriage and with the bevel face 45 of the lever- 42-pressed- -agai nst the cam surface46,the'engagement of the faces 45 and 46 preventing accidental engagement of the other pawl tooth 41 with, the rack teeth: ear the e nwaramwe ment of the carriage- 3.3 the extension 43 of the lever 42 strikes-the. lower pin 34 on the rack bar, wherebyas the carriage continues its downwardmovement to the limit, the lever 42 is snapped over the cam face 46 and the lower. pawl tooth41 is brought into engagement with..the rack bar as shown. 7

- in Fig. 12. Downward movement of the carriage 33 may be stoppedby the engagewith the projection ment of the tooth 41' 61 on therack bar.

Upon upward movementof the carriage,

thepawl tooth 41-' will trail over the rack teeth and 1 prevent immature downward movement of the carriage before it has reached 1ts upper limit and at or adjacentthe top of its stroke, the extension 43 on the lever 42. will engage the pin 34 and snap the lever 42 back to its original position.

Coiled about the headed pin 40 and exertinga spring action on the lever42 is a coil spring 47 for snapping the depending arm 44- and its bevel face 45 over the cam surface 1 .VVhen the operator releases his'grip'on the handle the article will have been delivered to him, at 77 (Fig. 1), and the automatic return. means starts the carriage 33 in its upward movement to normal position.

This 1 automatic return Ineans comprises a spring'lll attached to the bar 23 as shown 1n-F1g.5. I r r It Will be seen by refer in to Fig. 12

a the coins are held in the coin channel 65 by the pin 1 during the entire down stroke of the carriage The carriage 33having now started its upward travel the hook shape' port'ion 50 of the coin .ejector'lever 49;: comes in contact with the eoins 51 (F g 9')-1n the coin channel andpushes them upward whe'ethey' are engaged by the spring hook 64 and forced into-the-com chute '67 where'thfey fall by gravity into the coin box 95 V a The carriage continues its upward move ment until the spring- 58 snaps the hooked locklever 54 into the lower depression 31,"

the lever; 49 havin g returned to normal position againstits stop lugj55 after the same had passed the coins in the coin channellduring the'downward stroke.

When the lock lever 54'has been snapped into its locked position as shown in Fig. 7 of the drawings,thelateral extension 43 .of the spring pressed lever 42 has struckthe upper pin- 34 swinging the depending arm .44 and its bevel face over the cam surface' 46: thereby reversing the crescent shape double acting pawl 39- into position shown in 7 ofthe drawing, wherein the upper pawl rests against the upper depressed por tion 3110f the rack bar. The coin control mechanism is now in'normal locked position. 7

ready; for the reception of coin andforthe mssgess operation of the handleto deliver another article.

. Referring more particularly to .--Fig; 18

of the drawing, the coin channel 65 is more clearly illustrated and a better understand ing ofthe same may be had by reference to this figure. 66'isfthe'slot portion adapted to receive the inturned portion 64 of spring 62 to engage a coin as heretofore .described. The slot 66, it will be seen,,is formed in the channel forming flange 79 otthe coin channel 65. A longitudinal slot 7 8 running substantially the entire length of the'coin channel 65 which is adapted to provide a v from the spirit-of What-I claim is:

trackway for the hooked portion ofithe coin ejector lever 49 heretofore described. The ends of the coin channel-6'5 are closed preferably by means of plates 81 which aresecured in place in any suitable manner such as by bolts 82 engaging suitable opening 83. The bolts 82 also'function to hold. the coin channel assembledon the side wall :28.
