KREUZNAGH, GERMANY COIN-FREED VENDING- MACHINE Application filed October 2 3, 1929, Serial No.

The present invention relates to automatic vending machines of the type in which the, goods are delivered subsequent to the insertion of a number of coins. The object of the 5 invention is to provide means for recovering from the automatic vending machine prior to ..the delivery of the goods, any coins which have already been inserted. Such an arrangement is necessary with automatic vendmg machines in which the goods are delivered after the insertion 01%. number of coins be cause the purchaser may find that he is mis- .taken as to the number of coins in his possession and then must be able to recover the .coins which he has already inserted.

According to the present invention this problem is solved by providing the coin chute,

in which the'inserted coins are held prior ,to

their passage to the release deviceand to the coin collector until the complete number of coins have been inserted, with an aperture which normally is closed but can be opened by means of the action of a press button or the like provided on the-exterior of the automatic vending machine and operated by the purchaser, whereupon the coins which have been inserted fall into a receptacle-which is accessible from the outside of the machine,

whence they can be removed by the purchaser.

The arrangement according to the invention can further be such that the recovery of coins from the au matic vending machine is possible only be ore the complete number of coins requisite for the delivery of the goods has been inserted but is no longer possible after the last coin has been inserted L in the automatic'vending machine. For this purpose, according to the invention, the coins drop on to an arm of a balance, the .free

' end of which projects into the coin chute,

the balance being so adjusted that the arm is only displac ed by the weight of the coins w when the complete number of coins has been inserted and then allows the coins to pass to the release device of the automatic vending machine and to' the container in which the coins arecollect-ed.

The arrangement can be used in the case when a plurality of apertures for the inser- 59 tion of'coins of different values and a corre- 401,704, and in Germany llovember 3, 1928.

chute 1 where they are in the first place retained by a stop device 2 the action of which is described more full below. In the wall of the chute and pre erably directly above the stop ,device 2 is provided an aperture 3 which preferably is in the form of an clongated aperture extending in a vertical direction and which is normally closed by a correspondingly'shaped flap member 4 which is mounted on the pivot 5 on the outer wall of-' the coin chute 1. By pressing-the knob 6 the flap member 4 can be caused to uncover the aperture 33H? desired by the meet an intermediate gear such as a double-armed lever 7, the lever 7- and the flap member 4 then assuming the positions 7', 4 indicated in dotted lines in Fig. 1 and the coins in the chute fallwthrough the aperture 3 into the receptacle 1.0 which is accessiblefrom the outside of the machine and from which the coins can be removed.

As shown in Fig. 2 the flap members 4 in the two coin chutes 1 are actuated by a common pressbutton 6 by means of the lever 7 and a rod 8.

The coin chute 1 can be closed approxi- I matelyat the level of the lower edge of the aperture 3 by vmeans of a movable closure member 2-, which after all the coins have been inserted allows the coins to pass to the release device. In this case it is possible to recover the coins even after the insertion of the last of the necessary npmber of coins. It is preferred however for practical use to arrange that the possibility of recovering coins is only present until after the insertion of the penultimate coin whereas after the insertion of the last coin the vending device immediately becomes operative. For, this.

purpose the closure member 2 in the coin chute is constituted by an arm of a balance 9. The arm 2 of this balance, which may be a wei ht or spring balance as desired, passes into the coin chute 1 and the balance is so adjusted that the arm 2 remains in position to retain the coins until after the insertion of the penultimate coin but after the insertion of the last coin is displaced by the total weight of the coins and allows the coins to pass to the delivery device, preferably operating automatically, and tothe container in which the coins are collected. The balance can be adjusted as indicated in Fig. 2

by positioning a counter-weight or by alter-' ing' the setting of a spring and thus adapted to the w eight'of any number of coins which has to be inserted.

I claim 1. In an automatic vending machine, a coin I chute having a coin-delivery aperture in its wall, movable means normally closlng said aperture, means operable outslde of the machine for moving said closing means thereby to open the apertureQand means for supporting coins in said chute in position to pass successively through said aperture, said supporting means being automatically shiftable under the weight of a predetermined number of coins thereby to move said coins out of said position and prevent delivery thereof through said aperture.

2. In an automatic vending machine, a coin chute having a coin-delivery aperture in its wall, movable means normally closing said aperture, means operable outside of the machine for moving said closing means thereby to open the aperture, and a pivoted member extending into said chute for supporting coins in position to pass successively through said aperture, said member being adapted to swing on its pivot under the weight of a predetermined number of coins thereby to move said coins out of said position and prevent delivery thereof through said aperture.

3. In an automatic vending machine, a coin chute having a coin-delivery aperture in its wall, a pivoted member normally closing said aperture, depressible means operable out 53 side of the, machine for operatingsaid mem-- her into aperture-opening 7 position, and a pivoted member extending into said chute for supporting coins in position to pass succe'ssively through said aperture, said member being adapted to swing on itsv pivot under the weight of a predetermined number of coins thereby to move said coins out ofsaidposition and prevent delivery thereof through said aperture.

In testimony whereof I afiix' my signature. "PAUL SEI TZ.
