To all wh-om t may. concern:

Be it known that I, GEORGE W. GoMBnR,

la citizen of the United States, residing at higher denomination, the arrangement beingA such that the actuating mechanism maytin most part, be the same for dellvering a smgle article or a multiple thereof.

The invention is designed primarilyv for 'use 1n connection with clgar vendlng machines where it is customary to sell six 5 cent cigars for twenty-five cents or three 10 cent cigars for twenty-fivel cents or some other .such arrangement.

The vending machine embodying the invention is provided with a slide structure having an accessible end by which it may be'manipulated. The slide structure is ar ranged for connection to the vending or delivery side of thevmachine which may be of appropriate structure but. which does not enter into the present invention. A vending or delivery mechanism well adapted for use in connection with the coin-controlled mechanism of the presentinvention is shown mined-- number of reciprocations of the push bar to ultimately release the latch mechanism-to its first osition.

By the provision of two machines, one of which is set for single strokel operation and the other of which-is set for multiple stroke operation, it is possible to vend a single cigar for ve cents or six cigars for twentyfive cents, as the case may be, or any other chosen relation of vending.

The in-ventlon will be best understood from aconsideration of the following detailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that, while the drawings showa practical form. of the invention, the latter is not confined to any strict conformity with the showing of the drawings but may be changed and modified ,so long as such changes and modifications come within the scopeof the appended claims.

In the drawlngs:

Figure l is a side elevation of a coin-controlled mechanism embodyin the invention and showing the twentyve cent side j thereof; v

Fig. 2 is aplan view of thestructure of Fig. 1, with some parts in cross section;

.Fig 3 is a view similar t'o Fig. 1, but viewing the other face thereof and showing the five cent side;

Fig. 4' is a longitudinal' upright section i taken back of the face plate shown in Fig. 1, and also omitting some of the parts;

Fig. 5 is a section on the ine 5.-5 of Fig. it; Fig. 6 is a view similarto. Fig. 1, but

with the push bar at the other extremity of its stroke and showing the arts in position for vending numerous artic es for one coin;

Fig. 7 is a perspective view of a main por# tion of the push bar;

Fig. 8 is a perspective View of a portion of the latch mechanism.

Referring to the drawings, there is shownv a casing 1' in which the 'coin-controlled' mechanism is'housed and which maybe of suitable configuration.

any`

he coin-controlled mechanism includes anintermediate plate'2 and ilankin plates 3 and 4 respectively secured to the ate 2 in any suitable manner and spaced t erefrom vby spacing strips 5 or by any other'means gated strip havinga recess 9 in one ed e,v

which is the upper 'edge in the instal ed position, such recess being of an. eX-tent .lengthwise of the bar aboutequal to or a the recess 9. The recesses 9 and 11 may beA of the same size, or the recess 11 may more nearly correspond in extent to the diameter of a five-cent piece. The bottom edge of each notch or recess is beveled as indicated at 12, with the bevel directed' outwardly..

ln each plate 3 and 4 there are openings 13 and 14 respectively, into coincidence with either of which the recess or opening 9 or 11 may be brought. The bottom edgesbf the openings 13 and 1.4 are beveled as 1ndicated at 15.

Leading from the exterior of the casing 1 to a position to discharge over the openin s 13 is a double coin chute 16,v that is, it 1s provided with two channels 17 and 18 respectively, these channels being accessible from the exterior of the casing and may have mouth portions Vor cover plates of customary character, of such size as to admit a designated coin but no others. For instance, the coin chute channel 17 discharging opposite the opening 13 of the plate 3 may be -arranged to transmit quarterdollars, while the other channel of the coin chute may be arranged to transmit livecent pieces or nickels.

The arrangement shown in the drawings with respect to the coin chutes is of the simplest kind, but it will be understood that if so desired, various devices for preventing the use of anyl but proper coins may be employed.

When a coin is lodged at the opening 13, it is in positionto drop into the recess 9 when the push bar is suitably locked with respect thereto, and when the coin is in the recess 9, it is drawn by the push bar toward the opening 14, which latter is large enough to permit the coin to escape, such escape being facilitated by the beveled edges 12 and 15. If the coin be too small, it will escape through the opening. 13, being facilitated in such escape by the beveled edges 12 and 1 5 of the recess 9 and the opening 13. In this manner, a coin such as a ten-cent piece or a cent will fail to operate the machine, because it will not remain in the recess 9 ofthe bar 6 while the latter is being manipulated to operate the vending side of the machine.

The bar 6 along one edge is provided with a series of teeth 16*1 and also with a notch 17. The teeth 16a are engaged by a double tooth rock pawl 18a pivotally mounted by a screw 19 or yotherwise on the plate 2 and 'controlled by a spring 20'so as to yield to the passage of the teeth 16 but be held in engagement with` some one of them. finger 21 is carried by the bar 6 so as to engage one or the other ofthe teeth of the pawl 18EL and cause it to rock.

The teeth 16El and pawl 18*t constitute a full stroke device necesstatin the movement of the push bar 6 toits fu l extent and preventing partial movement thereof. vThis feature, however, does not enter particularly into the present invention, and is furthermore of known construction, wherefore further description is deemed unnecessary.

Also mounted on the push bar 6 so as to move therewith is a pawl 22 with a nose end 23 and a weighted end 24, the latter being heavy enough to overbalance the nose end and normally rest upon a stop bracket 25 carried by the ush bar. In the path of the nose end 23 o the pawl 22 is a circular series of pins 26 mounted on a disk 27 between the plate 3'V and a bracket 28, the disk being rotatable about its axis with the bracket 28 bearin with some frictional pressure upon the dis which latter is provided with a pintle 29 to support it. The pins 26 are all of the same length except one pin 26a, which is longer than the other pins,

but all the pins are so disposed withrela-' tion to the pawl 22 as to be engaged thereby for turning the disk ste reciprocatory movement ofp the bar 6 participated in by the pawl 22 carried by the vMounted on the plate 3 is a rock member 29 having three arms 30, 31 and 32 respectively. One arm 30 has a normal position nearly upright, and is formed on one side with a shoulder 33 for a purpose to be described. The arm 32 is counterweighted to overbalance the rest of the device 29, and the arm 31 is bent to one side to be out of the path of the pins' 26 but in the path of the pin 26B.,

Mounted between the plates 2, 3and 4 is a cam block 34 having cam members 35, 36v extending into the spaces between the plates 2, 3 and 4 so as to be in the path of coins inserted in the machine. The cam block 34 carries one end of an arm 37 projecting toward that end of the push bar 6 containing the notch 17a, and at such point the arm 37 carries a tooth 38 in position to enter the notch 17a. The arm 37 is also provided with spaced pins39 and 40,- the pin 39 acting-as a stop pin for the arm 30, and the in 40 being positioned toenga e the shou der 33 under circumstances to 5e described. A normal tendency to move in one direction is imparted to the push bar l(S by a spring 41.

When the machine is installed, the mouth of one or the other of the coin chutes 17 and 18 is closed, so that only one of the coin chutes is exposed, and this is the one leading to the part of the apparatus which will by step by the -of cigars for one coin.

- that the machine is set to vend a single cigar for a single coin, such as a ve-cent piece. Under these circumstances, the coin chute 17 is closed and the coin chute 18 is left open, the latter leading to the part of the machine responsive to a five-cent piece. On

the insertion of such coin, it drops to the bar 6, which latter is in the retracted position on account of the normal action of the spring 41. The recess l1 of the supplementary bar l()v belonging tothe bar 6 is at the time beneath the coin chute, wherefore the deposited coin drops into th'e recess 11 and there lodges. Now, on pulling out the bar 6, which has a limited lost motlo'n, the deposited coin engages the proper side of the cam block 34, causing the cam block with its-arm 37 to rise a short distance. This distance is sufficient to carry the tooth 38 out of the Anotch 17x71 and thereby permit the full stroke of the bar 6, which -full stroke would other- Wise be prevented by the engagement of the tooth 38 in the notch 17 a. rlhe desired forward stroke of the bar 6 may then be accomplished and the cigar or other article be v vended.

If it be that the machine is set for vending several articles ,in .succession for a single coin, then the device is initially set to permit the insertion of a coin such as a quarter in the coin chute 17. Under these circum-A stances, the larger coin, on engaging the proper portion'o thecam block 34, say, the cam portion 35, raises the cam block to a greater extent, thus lifting the arm 37 until it is higher than the shoulder 33, whereupon Athe counterweight-32' causes the arm 30 to move so that. the pin 40 will rest upon the shoulder 33, thus holding the arm 37 and cam block 34 in the elevated position. There is now no impediment to the repeated reciproca-tion of the bar 6 which may be continued until ultimately the elongated pin 26SL is brought into engagementl with the arm 31, causing a rocking of the arm30 to Acarry the shoulder 33 out of the path of the for ten cents and three cigars for twentyfive cents, or six cigars for fifty cents, or any other amount desirable.

To surely discharge the inserted coins after causing the release of the coin lock, the

plate l2 opposite the openings 13 and 14 has cam lugs 42 with one of which lugs an inserted coin engages and is positively eJected r'may be.
