MECHANISM.

SPECIFICATION forming part of Letters Patent No. 650,427, dated May 29, 1900.

Application filed January 11, 1900. Serial No. 1,133. (No model.)

To aZZ whom it may concern.-

Be it known that I, MAX SIELAFF, a subject of the King of Prussia, German Emperor, and a resident of 23 Spenerstrasse, Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Coin-Freed Mechanisms, (for which application for patent has been made in Germany, No. 16,492, on the 3d of March, 1899, and in France, No. 283,349, on the 12th of December, 1899,) of which the following is an exact specification.

The present invention relates to improvements in coin-freed mechanisms, and has for its object to provide means for opening the receiver when the mechanisms are not in position for use, so that in consequence all coins inserted are conducted to the outside again.

lVith coin-freed mechanisms hitherto employed the driving mechanism oftenwas injured by coins inserted into the apparatus while the particular parts were not in the right position for taking up the coins or were not in the position to be coupled by the coins.

By the mechanism forming the subject-matter of the present application coins are prevented from being inserted into the apparatus when the different parts are not in right position. The particular construction for attaining this end consists of a coin-receiver having two parts elastically connected together, one of which by means of a crank-lever can be removed from the other, whereby this crank-lever at its free extremity is of a form that not only the rotating slide usually employed but also the driving mechanism can effect its displacement as soon as the latter leaves the position for taking up the coins.

My invention will be better understood with reference to the accompanying drawings, in which- Figures 1 and 2 represent lateral views of my apparatus, and Fig. 3 is a plan View of the rotatable slide and showing a sectional view of the end of the lever m. Fig. 3 is a horizontal sectional View of the driving-disk and 1ever m and showing in plan the rotatable slide in connection with these parts. Fig. 4 is a plan View similar to Fig. 3, showing a slightlydifierent construction of slide. Fig. 5 is a View similar to Fig. 3, showing the drivingdisk here having angular recesses instead-of rounded ones.

In the drawings a coin-freed mechanism for distributing liquids is representedas an example. The apparatus essentially consists of a cook a, the plug of which is moved by the rotating driving-disk b. The movement is imparted to the disk I) in known manner from the exterior by means of a slide a, coupled with the disk h during a part of the rotating movement when a coin has fallen into one of the slots cl of the disk I). The slide 0 has a portion of its perimeter removed, as shown at 00, whereby the slide will be permitted to be rotated to an extent equivalent to the length of the cut-away portion. In its rotation when the parts are in the position seen in Fig. 3 the points 00 00 would strike against the projection 0 of lever m, presently described, and thus the rotation of the slide a would be limited in each direction. The slide 0 has sector-shaped portions y formed by cutting away the slide, as at z 2 Above the driving-disk b is arranged in suitable manner a coin-receiver consisting of two parts f and g. Both parts f g are connected together by a joint h. The part fis fixed, while the second part g can be turned. In normal position both parts are kept close to each other by means of a spiral spring '5. Underneath the coin receiver there is arranged a funnel discharging all coins falling out of the coin-receiver. When the coin regularly has passed the receiver, it enters a coin-channel Z and is conducted to the driving-disk b. A double lever m is rotatably fixed to the casing e at n. The form of this crank-lever m clearly can be seen from Figs. 1 and 2. The upper part abuts against the movable part 9 of the receiver. The lower extremity is provided with two projections o 0 the lower one of which extends into the path of the circularslide 0, while the upper projection 0 abuts against the disk b, as can be seen from Fig. 3. The periphery of the disk is provided with a number of depressions 10, corresponding to the number of the slots. The position of the parts is arranged in such a manner that the lever m or, more precisely, its projection 0' only extends into one of the recesses 19 of the driving-disk, when the lat ter is in position to take up a coin. Fig. 3 shows the parts in position ready for receiving a coin, and if the coin is dropped into the receiver it will fall down into a slot (1 of disk b, at which time the sector y of slide 0 is below the said slot 01; but by rotating the slide c-say in the direction of the arrow in Fig. 3the sector 11 will first clear the coin resting in slot d, which coin will then drop down partly into space 22 of slide 0, and as the slide 0 is continued to be turned the other sector 1 will strike the coin, and thus cause the disk I) to be carried around with it in its further rotation, and thus turning the plug of cook a, the coin thus constituting the looking medium between the disk I) and slide 0. As soon as the disk is removed from the position for receiving a coin the projection 0 of the lever m advances and lies upon the cylindrical part of the disk, whereby the lever is displaced, the coin-receiver opened, and no coins are allowed to enter the coin-channel Z,and consequently to enter the apparatus.

My improved arrangement is of great advantage for coin-freed mechanisms selling liquids for the reason that the liquid trickles down when the cock only is opened a little without it being possible for the whole movement to be effected. Furthermore, in this position no further coins could be inserted, and the apparatus cannot be used before the driving-disk is adjusted in position. When new such an apparatus does not work exactly, my improved arrangement prevents with certainty the insertion of coins, so that no buyer can be robbed of his coin. All coins being inserted when the apparatus is in inexact position are carried to the outside through the funnel k.

In Figs. 4 and 5 I show the slide 0 as being provided with a slight rounded or angular depression p to enable the operator to close the coin-receiver even when the rotating slide is not in its starting position.

Having thus fully described the nature of my said invention, what I desire to secure by Letters Patent of the United States is 1. In coin-freed mechanism, the combination with a coin-receiver adapted to be opened for discharging coins, of a crank-lever m, a slide adapted to be rotated from the outside for actuating the apparatus, a rotatable disk 27 for taking up the coins, said slide and disk being adapted, when not in position ready for use, to act upon the crank-lever and cause the latter to open the coinreceiver, all as specified.

2. Incoin-freed mechanism, the combination with a coin-receiver adapted to be opened for discharging coins, of a crank-lever m, a slide adapted to be rotated from the outside for actuating the apparatus and being pro vided with a peripheral depression, a rotatable disk I) for taking up the coins, said slide and disk being adapted, when not in position ready for use, to act upon the crank-lever and cause the latter to open the coin=receiver, all as specified.

In witnesswhereof I have hereunto set my hand in presence of two witnesses.
