This invention relates to coin controlled feed means-for counting or other machines 1 n which the counting or other mechanism is coupled for actuation to the feed mechanism by means of the coins. Hitherto the coins have been passed for this purpose through a channel in one end of which a pawl coacting with a ratchet wheel engages and which is forced out of the channel by the aid of the l coin. As there are coins of various sizes and thicknesses a separate guide channel had to be provided for each kind of coin so as to obtain the same degrees of angular movement of the pawl. This disadvantage is-overcome by the present invention and means for operating the ratchet wheel are provided which suits all kinds of coins.

According to the present .invention the coins are fed through the machine by two opposed rollers which are connected one with the other by a gear and revolve .in opposite directions, transmitting their peripheral motion to a coin engaged with a peripherally recessed disc connected with means for controlling the coin-feeding, and for varying and limiting the quantities of coins.

One form of the invention is illustrated in the accompanying drawings, in which Figure 1 is a view of the apparatus from above.

Figure 2 is a section on the line I-I of FiO'. 1 and Figure 3 is a section on the line II--II of Fi l.

Fig. 4 is a detail horizontal section on line 4-4 of Fig. 5, and

Fig. 5 is a section on line 5 5 of Fig. 4. The coins 1 to be counted pass out of the receptacle in which they have been collected or the distributing chamber through a mouth piece 2. Beneath this mouthpiece 2 are arranged rollers 3 and 4 on parallel shafts 5 and 6 respectively in such a way that these rollers are situated opposite each other in the direction of their diameters and a narrow slit 7 is left between the external surfaces of their peripheries, into which the coin l emergin from the mouth piece 2 drops.

he coin 1 gripped between the rollers 3 l0 and 4 in the slit 7 engages partially in one of ten recesses 8 in the periphery of a disc 9, which is carried on the driving shaft 10 of a counting or dispensing mechanism (not shown The walls of said recesses are forme as cams. Opposite the disc 9 a guide roller 11 for the coin 1 is mounted to rotate loosely on a lever 13 pivotally mounted at 12. This coin denomination selector lever 13 is provided with a handle 14 and a pin 15 which can be caused to engage in a hole 16 in a stationary plate 17 so as to enable the guide roller 11 to be held in a definite position corresponding to the size of the coin. A number of holes 16 are arranged in stages in the plate 17 to correspond to the various kinds of coins. l

In order to enable the distance between the rollers 3 and 4 to be regulated to correspond to the thicknesses of the coins the shaft 5 of the roller 3 is mounted in adjustable bearings 18 and 19. As shown in Fig. 4 the bearings 21 and 21 are fixed on a base plate 48 or the like. Bearing 19 is rotatable around pivot 23 of plate 48. Bearing 18 is di laceably mounted in sl'ot 49 of plate 48. pring 2O serves to keep bearing 18 apart from bearing 21 and to press it against regulating screw 22. Screw 22 regulates the distance between bearings 2l and 18 and consequently the distance between rollers 3 and 4. By this 50 means of having the spring press the rollers apart instead of toward each other, and regulating by the adjustment of the screw 22 the spacing of the rollers, the rollers are prevented from engaging and advancing coins which are worntoo thin, and if a coin which is too thin gets between the rollers the machine stops, thereby enabling the person operating the machine to recover the faulty coin. The bearing 18 is actuated byv a spring 20 which tends to move the bearing 18 away from the bearing 21 on the shaft 6. The movement of the bearing 18 is limited by means of a set' screw 22 arranged in a screwthreaded hole of a vertical stationary wall to form an adjustable stop encountered by said bearing 18. 'Ihe shafts 5 and 6 are connected together by toothed wheels 24 and 25 and are driven at the same speed by means of the bevel wheels 26' and 27 In a recess `8 in the disc 9 is engaged a roller 30 which is mounted on one arm of a two-armed lever 29 pivotally mounted at 29 and loaded by a spring 28 to control the movement of said disc 9. 0n the other arm of this lever 29 is mounted a pawl 31 which engages in a. ratchet and locking wheel 32 rigidly connected to the disc 9. Star wheel 9 is moved by a coin (the latter being moved by rollers 3, 4) at a certain angle controlled by roller 30. Roller 30, during this turning action, passes over a cam positioned between two recesses 8 and turns lever 29 insuch manner that part 31 of the lever follows and touches a tooth of wheel 32, cooperating with lever 29. The pressure exercised by toothed-wheel 9 upon roller 30 and lever 29 is thus transferred back, by means of wheel 32, to star wheel 9, and is used at the same time, and in addition to the driving force of the pressure of the coin, for turning the toothed wheel. Thus lever 29 engaging in the recesses 8 of the counting wheel 9 exercises, when actuated by the coins, resistance upon the counting wheel. This resistance is reduced by the action of the auxiliary pawl which engages in ratchet wheel 32, when the roller passes the tooth of the counting wheel, and thereby helps to overcome the resistance which roller 30 encounters on the tooth.

Connected to the disc 9 by the shaft 10 is a gear wheel 33 which engages in a ear wheel 35 provided with a pin 34. e

pin 34 strikes at each revolution of the gear I wheel 33 against one arm of a star wheel 36. (see Figure 3) and rotates h this latter through a fixed angle. The star wheel 36 is provided with laterally projecting pins 37 in the path of which an' arm 38 of a pawl 40 pivotall mounted at 39 projects while the tooth 41 o the pawl 40 engages in a notch 42 in a longitudinally movable rod 43 under the action of a spring 44 and thereby holds the rod 43 in its initial position. This rod 43 is actuated by a spring 45 which when the tooth 40 of the pawl is released from the notch 41 thrusts the rod 42 so far forwards that its front end 46 projects into the mouth piece 2 and thereby prevents coins from issuing from the mouth piece as shown Ain Figure 2.

The rollers 3 and 4 which rotate at thel same speed and in opposite directions grasp one coin after another and force each coin into'a recess 8 of the disc 9 thereby clearing the propelled coins of any injurious frictional connection. The coin 1 entering a recess 8 transmits the peripheral force of the rollers 3 and 4 to the disc 9 until it has passed these rollers and the recess 8. Between the rollers 3 and 4 and the disc 9 the coin produces a kinetic connection whereby the disc 9 is rotated through a definite angle. At the same time the locking roller 30 of the lever 29 will leave the recess and pass over mits one and the Vsame isc to be used for all the kinds of coins that may occur.

After a certain quantity of coins have beenpassed the disc 9 the machine is stopped When for example the hundredth coin passes in contact with the disc 9 a pin 37 on the star 36 strikes against the arm 38 of the pawl 40.

To reset ing locking bar 43 is retracted to the right (looking at Fig. 3), until the springpressed pawl 40 engages the groove 42 to kee the locking bar 43 in its initial position w ereupon the prescribed operations are repeated. i
