R. T. WRIGHT VENDING MACHINE Filed July 18, 1945 5 Sheets-Sheet 5 INVENTOR ZZa xra [MG/ 7%; i V14 5AM" A TTOR/VEY' I5. This connection includes a link I6, connected to the plate or lever I I, a lever I'I connected with the link I6, and a bar I8. The bar I8 is connected with the plunger I by means which are not shown in detail but which preferably include coin or check controlled apparatus,

which may be any one of many devices known in the art. It will be understood, however, that by pulling the plunger I5 the pawl I2 and its assembly may be moved back and forth.

During times of rest the magazines are locked in position by the latch I3 engaging in a notch I I. Means are provided for releasing the latch I3 incident to movement of the pawl. This means includes a cam I9 mounted on the pawl plate I4 and moving with the pawl, and a lever 20 engaging the latch I3. Here the connection between the lever 20 and the latch I3 is made by passing an end 28a of the lever through a hole I3a in the latch. The lever 20 is a lever of the first class pivoted on an appropriate cross member 2I of the frame, and has a lug 22 for engagement by the cam I9.

Fig. 8 illustrates the position of the actuating mechanism at the beginning of the stroke. The initial part of the stroke serves to disengage the latch I3. Rearward movement of the pawl assembly, including its plate I 4 and the cam I9 (from the position shown in Fig. 8 to the position shown in Fig. 9) brings the upper surface of the cam I9 into engagement with the lug 22 forcing it upward and the opposite end of the lever 20 downward, to lower the latch I3 out of engagement with the notch I I. The pawl I2 has by this time reached and engaged a notch II the same being moved into engagement therewith by a spring I2a, and the apparatus is in the position shown in Fig. 9. Further movementof the pawl assembly will rotate the magazines. As soon as the cam I9 is past the lug 22, as it is about to be in the position shown in Fig. 9, the latch I8 will be released and will return upwardly under the influence of a spring 23, attached to the outer end of the lever 20, and rest against the lower edge of the flange I 0 until the next notch II reaches it, at which time it will spring into latching position.

The cam I9 is pivotally supported so that on the return stroke it will ride over the lug 22, as shown in Fig. 7.

A spring 24 is attached between the plate I 4 and a member of the frame I, and performs the return stroke of the pawl assembly.

It will now be understood that upon pulling the plunger I5, the pawl assembly will be advanced first to lower the latch I3 by action of the cam I 9 against the lug 22, and then, by the pawl I2 engaging in a notch I I, to advance the magazines one step until the latch engages in a succeeding notch and stops the movement; whereupon the spring 24 causes the return movement of the pawl assembly.

Means are provided'for manually releasing the latch and the pawl, so that the magazines may be turned freely as is desired in loading or servicmg the magazines. This includes a plunger 30 connected to a lever 31, which has a cam 32 positioned to engage aprojection 33 on the latch I3. Thus when the plunger 30 is pulled the cam 32 slides over the projection 33 to depress the latch I3. An arm 34 is fastened to'the outer end of the latch I3 and is so positioned that it willengage and depressthe pivoted pawl I 2. Thus when the lever 30 is pulled out the latch'and the pawl are disengaged and held disengaged from the flange I0, permitting the magazines to be freely rotated.

As previously explained, each of the magazines 3 and 4 includes a series of radially disposed compartments so arranged that each compartment as specifically shown holds three bottles. Thus the magazine has a capacity to carry three annular rows of bottles. While the compartments are disposed generally radially about the axis of the magazine, they are curved rearwardly with reference to the direction of operational rotation. The sides of the compartments are formed by plates 35 which are secured to the bottom Illa of the magazine and'to a ring-like member 35a (see Figs., 3 and 10) supported on the said bottom and the ends are curved straps 36. These plates are notched at 35b to permit a bottle positioning lug, later to be described, to pass the ends thereof. The bottom of each compartment comprises the bar 'I which slants downwardly towards the periphery of the magazine. The arrangement of the bar I, which is passed through and secured to the member 35a and to the bottom Illa, is such that it supports the inner and intermediate bottle and supports the outer bottle when in a slanting position. But it is so arranged with reference to the outer portion of the compartment that a space is provided to the rear of the bar sufficient to permit the discharge of a bottle therethrough when the bottom of the bottle is shoved off the bar I. It has already been explained that a bottle in the outer row is shoved oil the bar I by the lug 8 as the magazine is rotated step by step.

The construction of the magazines and their compartments is such that when a bottle is discharged the other bottles in the compartment will, under favorable conditions and due to the slope of the bar 'I and centrifugal force, move outwardly. Nevertheless means are provided to positively move the bottles outwardly as the magazine is rotated. An overhanging arm 31 is adapted to engage the shoulder of the intermediate bottle immediately after the outer bottle has been discharged and push said intermediate bottle outwardly, While a lug 38 is positioned to engage'the bottom of the inner bottle and push it outwardly at about the same time or immediately following.

To assist in the smooth operation of the device the head of the intermediate bottle is engaged by a support or rail 39 whichsupports the head of that bottle while the outer bottle is being discharged.

The action in the movement of the bottles is illustrated in Figs. 10, 13, 14 and 15.

Fig. 10 is an elevational view which shows the lug 8 engaging the bottom of the bottle at the same time that the head of the intermediate bottle is supported by the rail 39, and as the arm 31 is engagin the shoulder of the intermediate bottle and just as the log 38 is engaging the bottom of the inner bottle.

Fig. 13 shows the arrangement of the bottles as a compartmentis approaching the delivery station. i

Fig. 14 is a .plan viewfof the bottles in approximately the same position as Fig. 10. Here the lug 8 is engaging the bottomof the outer bottle and about to'pus'h it ofi the support "I, while the head of the intermediate bottle is supported by the rail 39 and the arm 31 is engaging the shoulder of the intermediate bottle. The inner-bottle is approaching and about to engage the lug38.
