' Rows of one and of several :projections and 23' are arranged upon the drums 1S. 1! 20, 21 in a directiow parallel. to the Each .r ow of projections ow ofprojcctions :23 by one twcntiethot. the circumfel'cnce of a drum. ,l ligf i'ir sho wscthe de- "arms 111 are pivoted to a shaft 112 arranged in the casing 1. Each finger 24 and 2-1 rc spectively consists of two links, one of which being pivoted at one end to the rod 110, and

45 provided with ten teeth. -60

at the other end pivoted to the second link. The latter can be turned upward toward the other link. The ends of the said fingers rest on rods 25 connected to levers 26 acting on nn1ltipleway taps 27, 42, 43, 44. The tap 27 is adapted to control the passage of compressed air tog cylinder 28. The rod 25 is exposed to the action of a spring 25 en deavoring to bring the rod 25 into the inop erative position, in which a channel 113 of the tap 27 forms a communication between the cylinder 28 and the atmosphere by means of an opening 114.

" A piston 29 is arranged in the cylinder 28 and exposed to the action of compressed air controlled by means of the tap 27. The piston is connected by means of a rod 30 with a changeejecting slide 31. Fig. 5 shows a series of four ejecting-slides3l. 36, 37, 38 arranged the one above the other. Cach of the said slides is provided with openings 32, 33, each of which can receive a coin or one of small cases containing paper money. Ea h .ejectinglide can eject the coin or one of said cas s passed into the opening 33 .from the corresponding coin-magazine. A

movable bottonrplate 3' is arranged beneath the slide 38 and closes the openings of the said ejeeting'slides. When the plate 34 is .vithdrawn, the coin or case filling up one of the Openings 32 or 33 falls out of the latter into a channel 34'.

The ejecting-slide 36 is connected to a pis ton flfi the slide 37 is connected to a piston 40, the" slide 38 is connected to a piston 41. The cylinders of the istons 29,- 39, 40,41 are arranged one above t ie other, and have compressed-air passages, in which the taps .42, 43 and 44 respectively are arranged. The taps 27. 42, 43, 44 are provided with passages 115 adapted to communicate the cylinders of the pistons 29. 39, 40, 41 with the tube 116 in which one of the taps 117 adapted to regulate the pressure of the air-flow is inserted and which leads compressed air from the reservoir to the taps 27, 42, 43 44. A spring 35 tends to return the ejectingslides inttheir inoperative position and to force the slide 38 against the slides 37, 36, 31.

Each drum is secured to one toothed wheel A pawl 118 and pawls 46 and 47 can engage in each toothed wheel 45. ed loose and the pawls 47 are keyed on a shaft 48 and staggered to each other through half a tooth on engaging in the corresponding wheel 45. The pawls 46 are each pro- The pawls 46' are mount-.

vided witiinoses 49, the underside of which are pivoted at 50 and provided with pins 52. Each pin projects into a slot 53 or 53 respectively of links 54 and 54. The links 54 and 54 are connected to one arm of twoarm levers 55 and 55 respectively (Fig. 12 and Fig. 15). To the other arms 57 and 57' of the levers 55 and 55 rods 59 and 59' are pivoted at 58 and 58' respectively. A roller 60 is mounted on the rod 59, and a roller 60 is mounted on the rod 59. lVedges 62 and 62' each rest with the one side on stationary rollers (31 and 61 respectively, mounted in vided with a wedges 62.

The wedges 62' are progreater pitch than the provided with a shouldr64 and 64. respecfinger 24 or 24 respectively. Springs 65 tend to return the rods 59 and 59 in their inoperative position. Each pawl 46 is c0nnected by means of a rod 119 with a rod 67, rotatively mounted-on a fixed pivot 66. The lower end 68 of each rod 67 engages in the forked end of a rod 69, which is ro-tatively mounted on a stationary pivot 70 and provided with a cam 71.

A handle-lever 74 having four arms is pivotally mounted at 74 in the casing 1. The arms 74 are provided with openings through which the shafts 2, 4, 5, 6, 7 pass. The lever has an arm 120 (Fig. 116) provided'with a handle 121 able to slide in a slot 122 of the said arm and projecting through a slot 123. of the casing 1 out of the latter, for the purpose of being operated by the seller. One of the arms of the lever 74 is provided with an extension 124. which can act on a cam 125 rigidly connected with one of the said crank arms 111. If the lever 74 is in the inoperative position, shown in Fig. 3, then the said extension 124 by means of the cam 125 moves the crank arms 111 against the pressure of a spring 126 and returns the fingers 24, 24 by means of the said crank arms 111 and of the rod 110 in their inoperative position out of the path of the projections 23 of the drums.

shafts of the drums. Each lever carries (meet the said pawls 118 pivotally mounted thereon at 127. V A couplingmc'mber 76 having nose-shaped projections 128 and 129 is' movably arranged in each lever 75. Each coupling-member 76 is provided with a roller 130'and exposed to the aptionof a spring 78. These springs tend to pull the rollers 130 to the ends of levers 131 pivoted at 132 to the lever 75. A rod 133 is pivoted to each lever 131 and hasa forked end in can be engaged by a lever 51. The levers 51* the casing 1,.and with their opposite sides wedges 62 and 62 are keyed on rods 63 and The lower end of each rod 59 and-"59 is ,tively, each of which engages beneath al Levers 75 are pivotally mounted on the which a roller 131 engages. Each roller 134 is journaled on a rod 135, which is connected at 136 to a pawl 118. One end of the said rod 135 is pivotally mounted on a link 137, pivoted to the corresponding lever T5.

The lever Te is provided with four recesses 138, each adapted to receive the nose 128 of the corresponding coupling-member 70 for the purpose of coupling the lever 74 with the corresponding lever 75. The engagement, of the noses of these couplingmembers in the lever 71 is secured by means of guides 70 which are arranged on the using and along the edges of which the i5 noses 120 slide, which latter by means of the springs 78 are pressed on the guides. The guides 70 are provided with notches 80 and H1. in which the noses 120 can engage under certain circumstances.

"he casing 1 is provided at the top with slots 82 (Fig. 3) for receiving the amount tendered in payment of the purchase made. A channel 83 is arrangedbeneath each slot 82 and communicates with the same. A

shaft S-l rotatively mouutedin the casing 1 is keyed to lever-arms S5 to which coinpushers 80 are connected. An adjustable abutment SS is arranged in the wall of each.

channel 83. A movable cam 89 isprovided with a slot Z) into which a fixed pin 0 engages and projects into the channel 83 opposite each abutment 88. The coins or the cases containing the paper-money have to slide over the said abutments before passing into the coin- cylinders 91, 02 or 92 arranged beneath the channel 83. The cam connected to a link (Z pivotally mounted upon a member 6. A pawl 91 is pivotally connected to the said cam 89 and to the link (Z (Figs. 19 and 20). For example, if a coin slides ever an abutment 88, it will force the cam' 89 to slide upon the pin (3 out of its position of rest and thereby move a pawl 91 pivotally connected to the said cam 89, so as to rotate a spring-ratchet-wheel 00 through one tooth, the said spring-ratchet-wheel 90 is connected with one end of a. spring 8 and meshing with a counting-train. The other end of said spring a is fixed at 2. .One of such devices is pro- \ided for each channel 83 and the coins passing into the coin-cylinders are counted by means of these devices. A flap 93 is arranged above the coin-cylinder 92. This flap can be adjusted from the outside of the casing 1. and in the raised position as shown it will close the top of the coin-cylinder 92. thereby forming a sloping surface along which the inserted coins slide into the cylinder 01. The flap 93 will be turned downward (30 as shown in Fig. 3 in dotted lines, it it is desired, that the coins now pass from the channel 83 into the coin-cylinder 92.

, Each of the ejecting slides 31, 30, 37, 38

is provided with -one tappet 08, which on 5 the outward movement of the slide rocks a 0n the return of the slides into the initial position slide idly over the lever-arms 97. Each lever 96 is pivoted to a rod 95 connected at its other end 99 to a lever 100, pivotally mounted on the casing 1.' The free end of each lever 100 acts on a nose of a detent 101 which engages in the teeth of the spring-ratchet-wheel 90 stopping it. On the lever 06 being pivoted by means of the tap pet 98, each lever 100 ill be moved downward and thus disengage the detent 10.1 from its corresponding spring ratchet-wheel 90, so that the latter will run back by the action of its spring to the extent of one tooth, the ratchet-wheel being again directly locked in position by the detent engaging with the next tooth. a

Each ratchet-wheel 00 is attached to an axle 139 (Figs. 3, 17). Some axles 130 have keyed thereon disks 103. Other axles 13!) have keyed thereon disks 103. Each of the said disks 103 and 103 has fourteeth, which can engage in a toothed segment 10-1 or 104' respectimly, which are pivotally mounted at 105. Each of the latter has also four teeth. Each toothed sector 10 1 is coupled to one arm of a two-.armed lever 10 13. the other arm of which is pivotally connected to the rod 03. Each toothed sector 101 is coupled to one arm of a two-arn'ied lever 106, the other arm of which is pivotally connected to a rod Fig. 3 shows the disk 103 meshing with the sector 10-1. When the ejecting- slides 31 and 30 are pushed forward out of the position shown in Fig. 3. the tappets operate the detent by means of the levers 96 and 100, so that the ratchetwheel 90 runs back turning by means of the disk 103 the sector 104 toward the left into its Zero position and will move the wedge 62 connected to the rod 03 into its upper position. The disks 103 and 103' mesh with the sectors 101 and 101' respectively and the latter enter their zero position on the failure of the corresponding ('()lI1('. VllI1tl(:1'S 91. In the construction. illustrated in the drawings, the cylinders 02 and 02 are out of function. 7

Each ejecting slide shown in the t'lrawings can when operated eject only one coin out of the said cylinder 91. As the wheel 90 has ten teeth, the same will make one revolution, if ten coins pass the abutment and form the charge of the cylinder 01. Therefore, the wheel 90 will make one revolution in the opposite.direeticn, if ten coins are ejected by means ofathe ejecting slides from the coin-cylindeigfil. Each coin-r vliuder 91 should contain never more than nine coins, so that the wheel 90 passes its zero position only when the coin-cylinder is empty.

Primary coin-cylindersQl cause tlie actuation of disks 103. Additional coin-cylin ders 91 are provided, governing disks 103, which cylinders are only brought into use on the failure of certain of the primary coincylinders. The hubs 1 10 of the levers 75 pivoting on the shafts of the drums are connected with springs 1 11 (Figs. 12 and 15), each arranged in a recess of the corresponding tooth wheel 45, and the other ends: of which springs are each connected to the said wheel. These springs constantly tend to return the drums into their zero position. The return of the drums into the zero position is effected in the direction opposite to the hands of a clock and after the disengaging of the pawls 46, 47 and 118, as may be seen from the following: The pawls to are each provided with a wedge-shaped side tappet 142. Four springs 143 having two points are secured to the lever 71 (Fig. 16) for actuating the said tappels 112. On turning the lever 74 in the direction of the hands of a clock (Fig. 15) each spring slides along the side wedge surface of the tappet 142 of the corresponding pawl 46 without ati'ecting the latter, as shown in Figsl lo and 18. On the return movement, however, of the lever 74, in the opposite direction to that of the hands of a clock, the points of the springs 143 are so pressed against the tappets 11:! that the pawls -16 are disengaged from the toothed wheels 45, as may be seen from Figs. 15 and 18 showing the pawls in dotted lines. Each pawl 47 is provided with an arm 111 having a pin 145 projecting into the path of the nose 49 of the pawl 16 and adapted to be operated by turning the pawl it; in the direction opposite to that of the hands of a clock: For the purpose of showing the principle according to which this-dev ce changes. reference is made to Fig. 10. A rotary disk 8 is arranged concentrically to the fixed scale 9, and the rotary disk 8 is also pro vided with a scale. The divisions of both scales'are equal one to the other, and the figures indicating them run in. the same direction. The scale 8 is for the amount tendered, the fixed scale 9 for the amount to be paid. If, for example, a client has ten-- dered 5 marks and has only to pay 3 marks, then the seller moves the rotary disk 8 in the direction of the arrow, until its division 3 corresponds with the division 5 of the scale 9. At this moment, the rotary disk has been moved over two divisions. T his movement of the slide can be used for moving the drums into their operative position.

Instead of a rotary disk 8 a slide S referring to a modification and (Fig. 9) provided with a scale in combination with a fixed scale A is employed, as may be seen from Fig. 8. The slide is used for the indication of the amount tendered and the fixed scale A for the indication of the amount to be paid. If, for example, the amount to be paid amounts to. 3 marks and the customer has tendered 5 marks, the coin paid will be inserted in its corresponding slot 82. Then the indicator 14 is moved along the disk 10 situated in the zero position, until the indicator corresponds with the figure 5 of the said disk. The disk 10 is turned in the direction of the hands of a clock, until the figure of the disk is situated opposite the indicator 14. This relative displacement of the disk 10 with respect to the indicator has a result that the drum 20 is turned'and a projection of the same will pass into the operati\e position, in which it is held by the pawl 40, which engages in the teeth of the corresponding toothed wheel 45, in a position opposite that of the finger :24 adapted to control the operation of an ejecting slide which is able to eject one coin of the value of two marks. X ow, the lever 74 is turned in'the direction of the hands of a clock out of the position of rest I shown in dotted lines in Fig. 12. The lever 74, carrying along with it the levers 75, causes the drum 20 to be turned by means of the pawl 118, whereby the levers T5 come into the operative position II shown in dotted lines in Fig. 12, and the fingers 21 are moved under theaction of the spring 126 into the path of the projections 23. In this position of the levers 75, the nose 129 of each couplingnicmber 76 has reached the notch 80. The noses engage in the notches and stop the levers T5, while the noses 128 are moved out of the recesses 138 of the lever 74 and release the same. In this position the levers 75 remain standing. By turning the drums one projection 28 has been pushed against the linger 2-1 which forms a member of the two-inarks-cttins ejecting-device. The projection 23 will press down by means of the said finger 24 the rod 9.5 connected to the compressed-air tap +14 (Fig.3) and makes the latter to communicate the cylinder of the piston 41 with the compressed-air reservoir 3. The compressed air will pass into the said cylinder and move the piston 41 forward, so that the ejecting slide 38 delivers one two-marks-coin. After the delivery of change required the lever 74 is first turned farther in the direction of the hands of a clock, until the right points of the springs .143 have snapped behind the tappets 142 of the pawls 46. Then the lever 74 is moved downward, whereby the springs 143 turn the pawls 46 and 47 and 118 into the position indicated in dotted lines in F iig'Z 15. The rod 67 will be turned to the le shown in dotted lines in Fig. 15,and the cam 71 will draw the rod 133 and the arm 131 as well as the coupling-member 76 to the left and move the nose 129 out of the notch 80, while the nose 128 again engages in the recess 138 of the lever 74 and couples the latter with the lever 75. By this opera tion of all the coupling-members all the levers 75 are coupled with the lever 74,

whereupon by means of the latter the levers 75 are again turned opposite the direction of the hands of a clock into the position of rest.

wedge 62 will be raised, when the corresponding coin-cylinder 91 contains no coins. Onthe failure of the primary coin-cylinder arranged for receiving two-marks coins .the corresponding wedge 62 is raised. The said wedge forces when raised as shown in dotted lines in Fig. 12 the roller 60 to the right and turns the rod 59 around the pivot 58, so that the .lower shoulder 64 will pass to the left beneath the'finger 24 and raise the latter from the rod 25. This action of the rod 59 will prevent the finger 24 to drive the rod 25 into its operative position and to cause an operation'of the ejector for the cylinder earrying two marks. Now, if the lever 74 is turned in the direction of the hands of a clock out of the position I into the position II (Fig. 12), then the drum, 20 will be turned by means of the pawl 118, the projection 23 will strike against the finger 24, press the latter downward and carry the rod 59 along with it. This rod 59 will turn consequently the lever 55, so that the link 54 and with it the lever 51 is raised. a The said lever will turn the pawl 46 by means of the lug 49. out of the teeth of the toothed wheel 45, whereby the rod 67 is turnedinto that position (indicated in dotted lines in Fig. 12), in which the cam 71 operated by the said rod 67 will press by means of the roller 134 the rod 133, the arm 131 and the coupling-member? 6 .to the left, for the purpose of preventing the nose 129 to engage in the notch 80. By continuing the movement 'of the lever 74 in the direction of the hands of a clock the cam 71 will make the pawl 118 to be disengaged from the toothed wheel 45. In this disengagement-position of the pawls 46 and 118, the drum 2O w1ll rotate back under the action of its spring 141 but be soon stopped by the pawl 47 as shown in Fig.15. On this, return movement of the drum, the finger 24 is released from the, projection 23. The rod 59 will return into its position of rest by the action of its spring 65, thepartsfil, 46, 67, 69. 71 will return into their posltion of rest and two projections 23 will passinto their operative position above two fingers 24. The said fingers 24' form members of the one-mark e eCting-device. The lever 74 is turned fa'rther above the notch 80 in the direction of the hands of a clock, whereby the pawl 118 will carry the drum along with it, and the said two projections 23 will press downfon the said two fingers 24, until the, nose 129 has arrived at the notch 81. If two onemark-coins are present in the prilnar coincylinders 91, the corresponding wec ge (52 is set in the lower position and the rods 59 remain in their position of rest and the nose 129 can snap in the notch 81 for locking the lever 75 1n its operative position, whereby the fingers 24 are pressed down on two rods 25 connected with the taps 43 and 44 respectively, which will Communicate-the. cylinders of the pistons 40 and 41, which when operated will actuate the one-mark ejecting- slides 37 and 38, with the compressed-air reservior 3.

After the delivery of the two one-mark coins, the lever 74 is first turned farther in the direction of the hands of the clock, until the left points of the springs 143 have glided off from the tappets 142 (Fig. 15).

Then the lever 74 is turned in the opposite direction, thereby drawing the pawls 46, 47 and 118 into the position shown in dotted lines in Fig. 15, so as to release the drum 20, which then will rotate 'under the action of its return spring 141 into its initial position on the hub 140. The taps 43 and 44 will be drawn into their inoperative position, in

which their channels 113 communicate the cylinders of the pistons 40 and 41 with the openings 114, through which the compressed air can escape out of the said cylinders. so that the spring 35 will press the pistons 40 and 41 into their initial position.

If sufficient one-mark coins are not present in the additional coin-cylinders 91, the corresponding wedge 62' has been. raised by means of the ratchet-wheel 90, disk 103', toothed sector 104' and rod 61 T he wedge 62' will turn the rod 59 and move the shoulder 64' of the same info the operative position near the ends of the fingers 24' as shown in Fig. 15. By turning the lever 74in the direction of the hands of a clock above the notch 81 the projections 23 will pull the fingers 24 and by means of the latter the rod 59' down, which will turn the lever 55 and elevate the link 54 and the lever 51 into the position shown in dotted lines in Fig. 15. The lever 51 will turn the pawl 46 against the pin 145 connected to the pawl 47 and move the said pawls,46 and 47 in the position shown in dotted lines in Fig. 15. The rod 67 will be swung far to the left and the cam 71 brought into a position, in p which it forces therod 133, link 137, pawl tion shown in dotted lines in Fig. and

prevent the noses from snapping'in the notches 80 and the levers 75 from being locked, so as to allow their return-movement. Consequently, the drums 18, 19, :20, 21 and the disks 8, 9, 10, 11 connected thereto will rotate back in their zero position. The fivemarks coin thrown into the channel 83 will be pushed by turning the shaft 84 and the coin-pusher- 86 into the corresponding coincylinder 91. The coins ejected by the ejecting slides 3-1, 36, 37, 38 pass into a trough 107 (Fig. 3, 5*).
