Our present invention relates to coin-controlled vending machines, its object being a vending machine of this type which is of simple construction and reliable in operation. With this object in view, we suggest to 5 provide the machine, in addition to a handle, with a delivery device adapted through the medium of an inserted coin to be operatively coupled with the said handle and influenced by a spring which, during the ejection of the a article, is tensioned and after the releasing of the coupling restores the delivery device to its initial position.

In order that our invention may be fully understood, we shall now proceed to describe 5 the same with reference to the annexed drawings, on which:

Fig. 1 is a front sectional elevation,

Figs. 2 and 3 are cross sectional views along the lines 11-11 and IIIIII, respectively,

in Fig. 1,

Fig/i is a part sectional view along the line IVIV in Fig. 1 and Fig. 5 is a part side elevation looking from the right in Fig. 1.

The casing of the vending machine is designated by 1, the articles by 2. Said articles are piled up in a magazine formed by vertical guides 3 and 1. The lowermost article 5 contained in the magazine is seated on the flat bottom of a recess of a rotatable cylindrical body 6, as best seen in Fig. 2, said cvlinder being the delivery device referred to above. Centrally through cylinder 6 ex tends a freel rotatable shaft 7, to the right hand side end portion of which (see Fig. 1) is secured, by means of a screw 8, the hub portion of a member forming both a knob 9 and a disc 10.

The cylinder 6 is supported in bearings of the end walls of a cylindrical housing 11 which encloses it with little clearance. Its left hand side portion carries a crank 12, the pin of which is engaged by a spring 13. The upper end of said spring is connected to a stud pin 14. of the guide 8, the hub portion of the crank being formed as a ratchet wheel 15 cooperating with a pawl 16 for preventing the cylinder 6 from retrograde rotation.

Secured to the right hand side portion of the cylinder 6 are four plates 17, 18, 19, 20. Plate 17 is formed as a ratchet Wheel (Fig. 3) but so that its pawl 21 is adapted to prevent rotation of the cylinder 6 in forward direction. Plates 18 and are plain disks, whereas plate 19 is cut away along an S-shaped line (Fig. i) so that a socket for the reception of a coin is formed between said S-shaped. face of plate 19 and the disks 18, 20 on either side thereof.

The disk 10 has a projection 22 adapted to engage a coin supported in the said socket, a slide spring 23 being interposed between said disk 10 and disk 20, see Fig. 1. A lateral stud pin 24 on the pawl 21 projects into the path of the coin, a spring 25 being provided to force said pawl 21 into operative engagement with the ratchet wheel 17.

A' coin inserted into the slot 26 will fall through the coin chute 27 into the position shown in Fig. 3, wherein the projection 22, or a stop stud 28, prevents it from further downward movement. If now knob 9 is manually turned in a clockwise direction (Fig. 5 disk 10 with its projection 22 followsthis rotation so as to impinge against the edge of the coin which, consequently, causes the plate 19 and the cylinder 6 to rotate in the same direction.

Prior to the shoulder of disk 17 moving in to interlocking engagement with the corresponding shoulder of pawl 21, the latter is released by the pressure exerted by the coin on its stud pin 24, so that ratchet Wheel'17 and cylinder 6 can freely continue their ad vance movement, until the article lying Within therecess of the delivery cylinder reaches the horizontal portion of the wall of housing 11 and opens the flap valve 31, when it can be taken out of the machine by hand through the discharge opening 32.

During this rotation of the cylinder 6, the tension of spring 13 increases, until crank 12 reaches its lower dead center, whereupon it is drawn in upward direction by said spring. As to the coin, however, this is prevented from further rotation by a fixed stop stud 33 and forcibly discharged by the cam face of disk 19. During continued rotation of the cylinder 6 with the plates 17, 18, 19 and 20 into their initial positions, the disk 10 and the knob 9 are trailed by the slide spring 23 and thereby moved into a position which only slightly differs from the initial. If it is desired for, the knob 9 to exactly resume its initial position, the slide spring 23 could be replaced by a spiral spring, the ends of which are secured to disk 10 and to disk 20, respectively.

The ratchet wheel 15 need not'be toothed along its full circumference, and in some cases one single shoulder would do.

Thevflap valve 31 may be spring loaded so as to prevent accidental escape of the delivered article from the machine.

What we claim is 1. Ina coin controlled vending machine, thecombination of a rotatable article-deliveringcylinder provided with a recess for the reception of a coinsituated in a plane at right angles to the axis of the article-delivering cylinder, a manually operable member adapted to turn relative to said cylinder and provided with means for engaging said coin and causing the said cylinder to be coupled withsaid manually operable member-through the medium of the coin, ratchet means normally preventing said delivering cylinder from delivering an article and provided with a member projecting into the path of the coinso as tobe adapted to release said cylinder under the influence of the coin, a fixed stop stud adapted to cooperate with said coin recess'to force out the coin'from its coupling position, and a springengaging said delivering cylinder in such amanner as to be tensioned during the delivering movement of said cylinder and to restore the said cylinderto itsinitial position after the releasing of said coupling. 7
