4 Claims.

This invention relates to coin-controlled dispensing machines and more particularly to the means for handling the coin which is inserted to release the dispensing mechanism, so that the coin will be delivered to the money box, if the package which is purchased is delivered, or will be returned to the purchaser if the package is not delivered, as, obviously, either the package must be delivered or the coin must be returned.v

Difiiculty has been encountered in machines of this type, in that it has been discovered that by pulling out and then pushing back the operating handle very quickly the package will not only be delivered, but the coin would be returned.

The primary object of my invention is to provide a construction for handling the coin in which the coin will be retained if the package is delivered regardless of whether the operating means is operated quickly, or at normal speed.

As the means for retaining or for returning the coin must be operated during the time in which the operating device is moved from and, returned to its initial position, I have accomplished this object by providing means for retarding the operation of the coin returning means, so that it may not be operated until after the operating device has been returned to initial position, whereby the coin retaining means, which is operated by the package when it is dispensed, will have ample time to operate before the coin returning means can operate.

For a more complete disclosure of the specific means which I employ, reference is now made to the following specification, in connection with the accompanying drawings, in which:

Fig. 1 is a side elevation of the coin handling mechanism which is employed.

Fig. 2 is a detail sectional view taken at line 2-2 of Fig. 1.

Fig. 3 is a similar View showing some of the parts in a different position.

Fig. 4 is a detail sectional view at line 4-4 of Fig. 1.

Fig. 5 is a view similar to Fig. 1, showing certain parts in different positions.

Fig. 6 is a detail view of a portion of the coin retaining and coin returning means.

As shown in the drawings, the main operating device consists of a straight bar Iii having a handle at its outer end and a series of gear teeth on its top side arranged in mesh with a gear l2 on the shaft M. A wheel I6 is mounted on said shaft, and a bell crank lever I8 is pivoted at It, and one end thereof is engaged in a notch 26 in wheel I6. The opposite end of said lever has a shoulder 2| which is arranged to engage a shoulv der 22 on a locking lever 24, so that if no coin has been inserted and the bar It] is pulled out, the parts immediately become locked.

If a coin has been inserted and passes the coin testing means, it will lodge on support 25, in the position indicated at X in Figs. 1 and 6, so that, as lever I8 is advanced, it will push the coin against lever 24 and lift it out of locking position, permitting the dispensing operation to be performed.

By this movement the coin is advanced to the position indicated at y, in Figs. 1 and 6, in which position it is supported by two pivoted dogs 26 and 28 directly over a vertical partition 30, which separates the coin retaining passage 32 and the coin returning passage 33. When in this position if dog 26 is moved so that it is withdrawn from its coin supporting position, the coin will fall into the passage 32 and pass into the money box, and if the dog 28 is moved, so that it is Withdrawn from its coin supporting position, the coin will be returned.

It may be assumed that the package dispensing operation will be performed when the bar It] has been pulled out to its fullest extent and that a package will be discharged into a passage 34 at the rear side of the machine. Means are provided for operating the dog 26 when a package is discharged into said passage, which consist of a 30 shelf 35, which is pivotally mounted on a shaft 36, and is normally supported in a horizontal position in passage 34 by means of a counterweight 31. A lever 38 is pivoted at 39, and one end of said lever is arranged in engagement with a lug 56 on counterweight 31 and the opposite end of said lever is pivotally connected at 4! to an arm 62 mounted on a shaft 43. In some instances a second shelf 44, indicated in dotted lines in Fig. 1, is mounted at shaft 43, and is normally held ina horizontal position by counterweight 31, through the action of lever 38. A stiff wire 45 is connected to pivot 4| at end of arm 42, and is exline to the dotted line position of Fig. 5,.thereby pulling wire 45 rearwardly and swinging dog 26 sufficiently to withdraw it from its coin supporting position, so that the coin will fall into the money box. The same action will take place if the shelf 44 is swung downward by a package 5 closed at the opposite end, except for a leak hole the size of which is regulated by a screw valve 50. A collar 5| is secured on rod 41 and a spring 52 is connected thereto and to the cylinder, and normally acts to hold the rod in .the position of Figs. 1 and 2. A collar "54 "is also mounted on rod 41, in position to engage one end of dog 28, as shown in Fig. 2. As thus arranged, spring 52 normally holds the parts in the position of Fig. 2, in which position the dog 28 is held in an inoperative position. The lever I18 has a projecting lug 55, so arranged that, when the lever is moved from its normal position, after a coin has been inserted, the lug 55 engages collar 5| and pushes rod 41in the direction to withdraw it from'cylinder 49, .and thereby moves collar 54 out of 'engagement with one arm of dogz28 and into en- ;gagement with'the-otherQarm thereof, thereby moving the dog into its operative, or coin supporting position, as shown in Fig. 3, so that, when the coin is discharged from support 25, it will be intercepted by the dogs 1326 and 12-8 and held iniposition 1110f Fig. 6. Ifdog 26 is operated by the 'falling package, the coin will be retained as before described, but if no package is delivered the .coin will be retained in positiony until the lever I8 is returned to normal position and the return of rod 4'l to normal position is permitted. The return movement of rod 41 is, however, retarded by thepiston "48, the speed at which it is returned depending on-the adjustment of valve '50, which permits the air to escape slowly from cylinder 49, so that if the operating bar In is pulled out and pushed back quickly, the shelves 36 or 44 will have ample time to operate-dog 26 and discharge the coin into the money-box, before the dog 28 is movedtor'its inoperative position, and this may occur some time after the operating bar has been returned to initial position.

If no package is discharged, when the rod' 4! is moved back to its initial position, the dog 28 will be moved' to its inoperative position permitting the coin to be returned. I

With the above described arrangement it will not be possible to secure the package and the return of the, coin by pulling out and pushing back the operating bar very quickly, as the package 'will have ample time to fall and operate the do 26 before the rod 41 will be permitted by the dash pot to move'back sufliciently to operate the dog 28.
