shown in Figure 4. \Vithm the case 1 ismounted a shaft 5 on Figure 6 is a side elevation of the device which is rotatably mounted the master drum for rendering inoperative the change-eject 6 rotated by means of the crank 7. ing and recording mechanisms. This drum or hollow cylinder 6 isfitted 59 Figure 7 is an end view of the same. with four parallel series of radial teeth 8; Figure 8 is a side view of mechanism f air having nine teeth each series as shown,

these teeth being located in line of circumference and free to move in or out, their position being determined by the action of the springs 9 mounted thereon.

Four concentric spider wheels 10 rotate on said shaft 5 and are actuatedby a button 11 and stem 21 moving in a slot 12 in the drum 6.

A tenth tooth 13 which is pivoted by the screw 14 and held over out of line of the other nine teeth 8 by means of a spring 15, is employed only and at such times as a carry over becomes necessary during the'automatic act of substracting the amount of purchase from the amount of the cash paid.

The tooth 13 operates as follows :Vi hen the wheel 16, (see Figure 3) is at the position shown, the small boss 1? will be in the position shown, and if wheel 16 is rotated one or more teeth about its fixed shaft 18 in a clockwise direction. the boss 17 which is fast on the wheel 16 slides up against the end of the carry over guide 19 pushing it up towards the drum and in a position where its flaring edge will be struck by and serve to push over tooth 13 against the action of the spring 15 and hold. the carry over tooth 13 during the instant of its passage.

The carry over tooth 13 which is made operative is of course in the series of teeth next higher in value than the guide 19, that is the next higher decimal value.

Following the tooth 13 is a projecting lug 2O integral with the drum, which lug in passing crowds the carry over guide 19 down and into its non-operative position and the spring 15 throws the tooth 13 over out of line of the other nine teeth 8 or into non-operative position.

The stem 21 of the button 11 moves in a groove 12 in the drum (3; this groove has notches 22 on one side and the notches 22 are numbered from O to 9.

The spider wheel 10 rotating about the shaft 5 actuated by 11 is so proportioned that the number of the notch 2 to which the button is turned corresponds with the number of radial teeth Spushed outward into operative position by 10.

For a clear conception of the machine in questioin it may be described as being made up of four entirely independent series of mechanisms side by side, corresponding in general to a decimal system of units tens. hundreds, and thousands, or. in this case. the first series on the right of the machine, corresponds to pennies, the second series to dimes the third series to dollars, and the fourth series to eagles ($10.00), and theproblem handled along the decimal system as far as possible.

Each of these four series are entirely independent of the others except only at the point of carry over, when a lower system may, under proper circumstances carry one unit to the next higher system, and at the point where the paying out and return to Zero is controlled by a shaft common to all four systems.

I have described above the dispositions on the master drum as pertains to one of these four similar systems of mechanism.

Side by side with the parts of the master drum 6 partsshown in Figure 2, and above described, there are three other systems similar and similarly disposed and separated from each other a distance sutlicient to give proper clearance to the anions parts.

Referring to the wheel 10 the teeth of this wheel mesh with whatever number of teeth 8 may be projecting out through the drum 6 by the position of 11 and 10; also 16 rotates freely on shaft 18; said shaft 18 being fixed and carries the carry over guide 19 always in a vertical position as shown.

23 is a thin gear wheel and is fast to 16; and the gear 23 meshes with the gear 24; on the shaft while the gear 26 is back of 2% a suflicient distance to permit meshing with the gear 27 which is fast to and drives the change throwing cylinder 28 of its series (see Figure Fast to 27 and rotating with it is an auxiliary gear 29 designed to mesh with a wide face pinion 30 which fast on shaft 31; said pinion 30 has one third as many teeth as the wide face gear 29 on shaft 32.

Also shaft 31 carries a lateral cam fast to said shaft and by means of proper stationary guides and end play in the shaft 31 the first few degrees of rota ion of the shaft 31 and cam throws the wide face gear into mesh and the last few degrees throws it back out of'mesh. (See Figure 8.)

The continued rotation of 31 rotates the cylinder 28 until the point 33 in the wid. face gear 29 where the teeth are cut away, is rcachech which is the zero pos' ion for Q9 and 28 further rotation of shaft 31 will have no further effect on cylinder 28.

The shaft 31 is common to the wide face driving gears of all four elements of the 1'2. chine, that is shaft carries fou wide face pinions 30, 34, and 36, one for each element.

In ordinary transactions the several change making cylinders will be set at various positions and as a consequence to complete the rotation of the cylinders or return to Zero the wide face gears driving said cylinders must be ln'ought into mesh with and rotated through various arcs not the same in the different series.

Thus in making three turns of the crank it is certain that whatever position any cylinder may have it is sure to be rotated bacl; to the zero position.

In Figures 4; and 5 the change making cylinders 28, 37, 38 and are shown, more clearly in. the back viev" above explained these cylinders are set by the pinions 24, 41, 42 and 43 carried by sleeves 44, 45, and 46 on the shaft 25. The change throwing mechanism, that is the movements requiring the transmission of any appreciable effort or power are operated by the crank 47 and the wide face pinions 80, 34, 85 and on the shaft 31.

These change making cylinders 28, 37, 88 and 39 serve simply as supports for carry ing the various change ejecting contacts 48 and may be made in star or skeleton form if desired.

The change throwing cylinder 87 (see Figure 4) that is employed in the dime series (this being the most complete series) as it comprises one till 49 for nickels, two tills for dimes, one till for quarters, and one till for half dollars. Other tills can be arranged for if desired.

For each till and directly opposite to it a series of contacts 48 circumferentially disposed around the cylinder are shown.

For the dime cylinder 87 there are contacts 48; for the nickel till; and for each of the dime tills there are four contacts 48; for the till for quarters two contacts 48; and for the half dollars one contact 48.

Again for the penny cylinder 28 I have shown two tills for pennies and one till for nickels, the cylinder carrying four contacts for each penny till and one contact for the nickel till. I

Using-this same control and arrangement other combinations may be made, as for in stance for the penny cylinder four tills may be employed thus requiring only two contacts per till in place of four as shown.

Other arrangements in the number of tills of the various denominations can be made according to circumstances.

Directly under each circle of paying out contacts 48 and in line with them and their corresponding tills are a series of plunger bars 54 (see Figure 2) which are held in supports 55.

These plungers 54 are mounted and spaced so that in moving toward the left they strike and push out the piece of money located at the bottom 'of the till 49, the plungers 54 are returned to a normal position by the spring 53. i

The forward end of the plunger 54 is formed with a long flat hook 56 which is held while being free to vibrate about the rivet 57 and in the present design all the plunger bars 54 are similar with the exception of the following.

For the penny cylinder the plunger bar corresponding to nickels; for the dime cylinder the bar corresponding to quarters and half dollars; for the dollar cylinder the bar for $2.00 and $5.00 andthe eagle cylinder for $20.00.

That is in the design. shown. there are six plunger bars of the type shown by 58 and seven bars of the type of 54.

Bars 58 which are called master bars are formed with an L-shaped end 59 to which is attached a short link 60 free to turn at each end; and to the other end of the link 60 is attached an L-shaped piece 61 carrying an adjusting screw 62.

The bar 61 is secured to the shaft 63 and clasped about the hub of said bar 61 and free to rotate on the shaft 63 is a member 64 as shown in the Figure 4.

This member 64 is arranged with a small projecting tip 65 adapted to be engaged by the screw 62 and also has a lip 66 just riding on the projecting portion 67 of the hook 56.

This arrangement forms a to gle joint or rapidly increasing movement of the piece 64 by the forward action of 58, and by its action lowers the hook 56 downward and out of engagement of the contacts 48.

For the penny cylinder and that for eagles (unless $50.00 contacts are added) the shaft 63 is continuous; but for dimes and dollars the shaft 63 is separated into two pieces by a clutch 68.

This clutch 68 is of a design permitting rotation of the longer portion (toward the left in Figure 4) without rotation of the shorter portion, but any rotation of the shorter portion will rotate the longer portion, and it will be seen that any bar 54 can operate without interference with any other bar, but the bars 58 in operation rotate the shaft 63 and the member 64. which may or may not carry the toggle joint arm, and in this way the bar 58 by its action, lowers out of engagement all hook pieces 56 located on its particular cylinder, such hooks corresponding always to the plunger bars of a lower money value than the bar 58 which is acting. This principle is one of the main features.

Thus in cylinder 37 the contacts 48 by their rotation will push over and cause to function successively the plunger bars for the nickel and dime tills, but as soon as the bar 58 moves forward the hook piece 56 for dimes and nickels are pusheddown and become inoperative and bar 58 is notmoved; when bar 58 is moved forward by its action of the contact 48 the rotation of shaft- 63 by the clutch 68 atonce rotates the longer portion of the shaft 63 and as before renders inoperative the expulsion means for the quarters, dimes and nickels.

Similar action is arranged for the change throwing mechanism of the other three series, such that at the operation of a plunger of high money value, all plungers of its system having a lower money value are rendered inoperative; however the duration of time through which the several bars are out of action is not the same; thus on cylinder 37 the books 56 should be held out of engagement during the advance of 72 degrees of the cylinder for the cent piece, while for the So cent piece the hooks must be held down during a rotation of l il degrees, this is accomplished by filling in behind the projecting contacts 48 with solid metal along an arc oi. length corresponding to the time of inaction required.

This is not shown in the figures except in the diagram in Figure 12 in which they are shown by solid black portions.

In the operation of the machine the crank 7 is rotated one turn forward and also one turn liiackward, consequently the gear wheel 27 and its cylinder 28 as also the cylinders of the other three series are actually r0- tated both forward and backward during the act 05 setting the cylinders tor the amount of return change required.

The anti-clockwise rotation of the cylin ders is provided for by sliding over and pushing down of the hooks 56 by the contacts L8 themselves, and for clockwise rotation of the cylinders 28, etc. by the action of the master drum it is necessary to depress all hooks 56 of all the plungers by some other and independent means later explained.

Referring to Figure 12 to describe more exactly the relative positions and value of the change ejecting; contacts, these diagrams show a development of all contacts on each of the tour cl'iange ejecting cylinders with the money value correspondnig to each as also the relative position of each as regard the others in its particular series.

Again referring to the dime cylinder, this being the most involved, this cylinder carries five rows of contacts secured on the surface thereof and spaced into ten equal parts oi 36 degrees each; each row of contacts corresponds to till (this is not necessary but shown as being most simple).

For this cylinder the nickel till has a ontact located at 108 degrees from zero, a second contact at 288 deg ees from PXVPQ tl c dime has the first contact at 86 degrees in one of: the rows; the next at 144; degrees, and a third contact at 252 degrees; while in the other row for dimes the tirst contact is at '72 degrees. the second at 2.16 degrees, and a third at 324 degrees, while tor quarters two contacts only are used, one located at 108 de grees from zero and the other at 288 degrees from zero; while t'or halt dolla only one contact is needed which isdocated at 180 degrees from zero.

It will be seen that the contacts for nickcls and dimes are shown as narrow strips while tor quarters and halt dollars they are shown as being continuous -tor a certain distance, that for half dollars being a solid segment extending from zero to 180 degrees; and for the quarter a similar ar' angement is made; effect of this as will JE'E later is that on the action oi? either master contacts and bars 58 the hooks 56 are held down by master bar 58 until the segn'ient has passed on and out of contact with 56; the object being as follows.

One of the important principles on which the machine operates is that, in the process of paying out upon the act of operating any ejecting element of a relatively high money value the ejecting mechanism of all lower money values of that series is automatically rendered inoperative.

It may also be noted that these contacts may be electrical contacts and may control a number of paying]; out stations, if it is do sired to operate the machine by an electrical current.

Referring to Figure 6 is shown a disk 74: secured to the shaft 5 of the master drum; a cam 69 is secured to said disk, and 70 is rod carry a small roller 71. at its upper enth and the l0.(:1' end of said rod 70 is held loosely in the hook it). It is held in light pressure against the forked guide and stop 73 by the spring (4:.

This T-shaped rod 70 is continuous throughout the length of the machine and as shown is loosely locked at 72 to each and all. of the hook pieces 56.

Now a the drum 6 is rotated in an anticlockwise direction the disk 74c rotating with it and by the action of the cam, the rod 70 is depressed and with it all the hook pieces 56 and the drums 28, 37, 88 and 39 may be rotated (backward) to the desired setting without throwing oi any of the till plungcrs.

All tills pertaining to pennies (pennies and nickels) compose one group; all dimes, quarters and halves another group (the nickel is added to this group in order to handle the quarter as it it was three dimes) all $1. $1. and it), tills in a third group; and finally all $10. $20. and. $50. tills in a fourth or eagle group; while in the dime group the same results may he obtained by arranging the nickel till either in, series or in multiples with the quarter till or in other words arranging the expulsion means in such a way that "from a. single Contact or plunger a nickel will always be thrown whenever aquarter is thrown.

The tills are all contained within the case of the machine and are so arranged as to be drawn out of one end of the machine so that they and their contents can be stored in a safe at night it desired.

Referring to Figure 1 of the drawings, the openings 41- are protected by sliding doors and communicate with separate compartments designed as receptacles for all money paid in to any clerk, a con'ipartment corresponding to each clerk, and each clerk having a. key for unlocking the crank 7 ot the machine: which operation at the same a3 cts a, des' eating letter or imiinljier in me ns the printing mechanism, and setsthe devices permitting the automatic opening and closing of the sliding door to a particular compartment during the operation of the crank 7. V

Access to the several compartments may be had only by the sliding doors, and by means of a panel in the backof the machine con-, trolled by a master key kept in the ofiice.

teferring to Figure 8 for throwing automatically the shaft 31 with its several pinions 30, 34., 35 and 36 into and out of gear with the driving gears 29, 29, 29 and 29 of the change throwing cylinders there is provided on the shaft 31 carrying the fixed, pinions that operate" the several cylinders during the process of actual ejection of the change; a wide face pinion 83 which is secured to the shaft 31 and 84 is a gear always in mesh with 83 and is secured to shaft 85; while 86 is a disk which is warped over to one side. at a point on itscircumference.

The disk 86 is secured to the shaft 85 and its circumferential edge rotates within the groove of the guide wheel 87 which is secured to the shaft 31; said shaft 85 being held against any end play. I

As soon as shaft 31 is rotated, the action of the eccentric disk 86 will at once slide the shaft 81 over and bring the gears 30 and 341 on same into mesh with 29 and 136; which position will be maintained until by the continued rotation of the shaft 31 the disk 86 has made one complete rotation, at which time the shaft 31 is returned or slid back by the action of the disc 86 to its original and out of engagement position.

For the recording and indicating devices I employ, referring to Figure 1 a shaft 88 on which is mounted a cylinder or drum 89 which is lined with rubber; said cylinder being so supported that it will freely vibrate either up toward the shaft 90 or downward toward the shaft 91, this rubber lined cylinder acting as a platin to the two sets of printing devices shown; and the same is actuated by means of proper cams carried by the auxiliary disc 74.

A continuous paper band is passed around this cylinder and is fed forward by gearing actuated by the rotation of the shaft 5; one set of printing wheels are shown by 92, 93, 91 and 95, and controlled by suitable spur gearing on the shafts 91, 96 and 18. 1

his printing mechanism is under the action of the carry over device 19 and is employed to register the amounts of cash paid in and the amount of the change paid out.

Another printing device is necessary and is shown mounted on the shafts 98 and 90; and this device does not have a carry over and is employed for recording the amount.

of the purchase and the clerks number or letter; and it is necessary that it be 1n gear only during such tiines as the teeth of the drum 6 are passing the wide faced gears 200, 201, 202 and 208; and to this end the shaft 98 isarranged with end play to permit the gears 200, 201, 202 and 203 to be thrown over and out of contact with the movable teeth 8 of the drum 6.

It will thus be seen that the mechanism for recording and indicating devices for the amount of purchase is entirely independent from that employed for the .cash paid and the return change, and should be in gear only during such periods of time as the teeth projecting from the master drum are passing the large toothed gears 204, 205, 20 6 and 207; and at all other times these gears mounted on the shaft 98 should be out of mesh which is accomplished without friction or throwing of any set of gears out of mesh as shown, by the sliding or end motion of the shaft 98, and with it the gears 204:, 205. 206 and 207; and in this way the former are carried to one side and out of any possible contact with the teeth project ing from the drum 6; and the gears 107, 108, 109 and 110 being made with Wide faces to prevent unmeshing with the gears 111, 112, 113 and 11 1. j

In this way and by the action of a pres sure roll 89 there can be no interference or misplacing of teeth.

The end movement of the shaft 98 may be controlled as shown: the rod 7 0 in Figure 6 carries a projecting lug 115 which on the downward movement of said rod strikes a lever 116 which is secured on a shaft 117; and also secured to said shaft 117 is the gear segment 118 which meshes with a rack 119 secured to the shaft 98, which carries the wide faced gears 20 1, 205, 206 and 207.

The return of the parts98, 118 and 116 may be accomplished by a spring or by the direct and positive action of the rod 70, the return of the rod 70 being already assured by the springs of the several hooked pieces 56.

It will thus be seen that by the clockwise rotation of the crank 6 that the rod 70 is swept over toward one side in its forked guide 7 3 and the rod 70 does not operate; while for anti-clockwise rotation of the crank 6 the, cam will depress the rod 70 throwing out of action all tills, and at the same time throwing into action the. recording and indicating devices for the amount of purchase, of all four systems, pennies, dimes, dollars and eagles.

For providing visible indications, both to the operator and to the customer there are provided three sets of visible counters or numbers for each of the four series of mechanisms already described; each series having a number wheel for cash paid, amount of purchase, and return change, or twelve number wheels in all.

For control of these purchase wheels, the setting of which must correspond with the setting of the two sets of printing wheels as also with the figures involved in any transaction or sale; there are added the wide face gears 99, 100, 101 and 102 on the shaft 90.

The racks 124 mesh in these gears and transmit their movement by suitable gearing on shafts 125, 126, and 127 and the number wheels 128, 129, 130 and 131; and in this way any position of wheel 99 and its train of gears is duplicated in the number wheel 12S and so on, by means of a rigid and positive transmission.

To hold the racks 124 and their train of gears in any position set by the action of the teeth I have arranged a simple eccentric 1ock'132 and a light spring 133 on the rack.

For index or number wheels for cash paid and return change the following mechanism is employed.

On the shaft or sleeve 91 are mounted the gears 134, 135', 136 and 137 which are formed with teeth on the side; these crown gears by suitable pinions 134 on the shafts drive similar crown gears 139 on the shafts 140 and 141; said shaft 140 drives the train of gears for pennies and dimes, while the shaft 141 drives those for dollars and eagles.

In Figure 11 the arrangement is shown of these gears for dollars and eagles only driven by shaft 141; while the arrangement for pennies and dimes is similar.

On the shaft 141 and rotating on the same is a walking beam 142 which is normally held in position by the spring 143 shown; and 144 is one of two flat members riveted together to form suitable supports for the two trains of gears for both the dollars and the eagles.

This frame 144 is mounted on the shaft 141 eccentric and free to turn; while the. fixed stud 146 serves to direct the line of motion of the frame 144; while a spring (not shown) tends to throw the gears controlled by frame 144 into mesh at the shaft 154 as shown, and out of mesh at shafts 148, 149 and 150 are studs sliding in grooves in the walking beam 142. Attached to these studs are suitable levers or looking arms 151. one for each series of gears. both for cash paid and return change.

From the walking beam 142 the lever 152 is attached and 152 is pivoted to lever 153; and the springs of 142 tend to hold this lever 153 in a horizontal position.

At the beginning of an operation on the machine, the lever 153 will be in the position 153 and by the clockwise rotation of the controlling disc 74 on shaft 5 but shown remote therefrom, for clearness in Figure 2, the projecting cam piece 220 will engage the end of the lever 153 and throw it down into position 153 thus raising the walking beam 142 andholding it in this position for a short period of time that the teeth of the drum (3 are acting on the wide faced wheel.

In the raised position of the beam 142 the levers 151 unlock their respective trains of gears, while the eccentric center of 144 which is fast to 142 will throw both gears on the shaft 148 and 154 into mesh with their corresponding index wheels; and on completion of the rotation of 74 lever 153 and walking beam 142 will, snap back into a horizontal position by the action of the springs shown for 142; and this last movement releases the locking arm 151 for the upper series of number wheels or cash paid, and throws the gear on 148 out of mesh and leaves the gear on 154 in mesh.

The drum 6 and the disk 74 being new rotated in an. anti-clockwise direction, the projecting cam 220 slides past the lever 153, the shaft 98 is movid as already described and the number wheel is rotated by the action of the teeth; and a projecting lug 220 is so arranged on the disk 74 that just be fore the completion of the anti-clockwise motion, of 74 it will engage the lever 153 pushing it up into position 153 This latter movement lowers the walking beam 151 and unmeshes the gear on 154; that is, at the end of the second operation of the crank 7 the gears carried on the shafts 148 and 154 are both out of mesh and the number wheels for cash paid and for re turn change are locked.

For the return to zero and to throw out the change the crank 47 is rotated su'liicient- 1y to assure the return of all the wheels 29, 136, 137 and 82 to the point where their teeth are cut away; this point is the zero point, and should the number wheels remain unlocked and in mesh these would return to zero at the same time; but as it is desirable that the record'of any sale should remain visible until the next operation of the machine I have adopted the following an rangement.

By this arrangement the first few degrees of rotation in a clockwise direction of the crank 7 and disk 7 4 the lever 153 is freed from the stud 155 and is allowed to drop toward the horizontal position freeing the lock rods 151 and permitting the instant return to zero of these number wheels under the action of the spring as shown; while the return to Zero of the printing and number wheels for amount of purchase is accomplished by freeing the lock t3 by means of a suitable control operated by 'disk 74, the return being brought about by gravity aided by a light spring.

Any usual style of totalizer may be driven by the gears 128, 129, 130 and 131 of the recording device for the amount of purchase, the only special arrangement being that through pawls or clutches in such a way as to permit the backward rotation of the gears for the return to zero.

The operation of the machine is as follows Suppose 75 has been tendered in payment for a purchase of 60 to clerk C. The clerk would insert his special key by which act shaft 5 would be rendered tree to rotate, the lettered index or printing wheel 203 would be set to record the letter C, and the latch for the sliding door to the receptacle 4 set permitting the opening and closing of the door by the action of shaft 5.

The button 11 for dimes should now be moved in its slot 22 up to the iig'ure T. The button 11 for pennies moved up to the tigure 5. The sequence of this operation is always immaterial.

The above operation as seen in Figure 2 will (a) rotate spider for dimes a distance sufiicient to force up into operating position seven of the teeth 8 of its group, and (b) rotate the spider 10 for pennies to position forcing up live of its teeth 8 into operating position.

'The shaft 5 and the master drum 6 is now caused to make one complete rotation in a clockwise direction by means or" the crank 7 or by other suitable means, and the two rows of projecting teeth, the one row ol 7 and the other of 5 will pass and engage corresponding teeth in wheels16, for pennies and 16 for dimes located just back of the former.

Fast to these wheels 16 and rotating with them are line toothed wheels 23 these wheels 23 transmit each its movement through the intermediate, and independent, transmission pinions 24. Each pinion 24 transmits its movement to its corresponding setting gear wheels 27, shown only in Figures 4 and I.

As these setting gears are fast, each to its corresponding ejection gear 29 and 29 (Figure l) and through its ejection gear to its proper ejection cylinder 28 and 37 it is clear that the cylinder 28*for pennies will be rotated in an anticlockwise direction, by its train of tour gears, to an amount corresponding to the 'fiveprotruding teeth of its master drum 6, the first and last wheel of each train being, as shown, of equal diameters the cylinder would be rotated 180 degrees. "In like manner. and with its similar train of gears the dime cylinder 37 would be rotated in an anticlockwise direction seven tenths of 252 degrees.

The button 11 for dimes is now moved to the figure 6 of its groove causing six of its corresponding movable teeth to protrude into operating position and the button 11 for pennies is moved back to its 0 finger permitting the return to inoperating position of all of its teeth. The shaft 5 and the master cylinder 6 are now rotated through one complete rotation in an anticlockwise direction; the six protruding teeth for the dimes will transmit through its same train of gears and in the same manner as before, a proportional movement of sixtenths or 216 degrees to its ejection cylinder 37, but this time rotating it in a clockwise direction, this dime cylinder now being in a position of 252 less 216 or 36 degrees in an anticlockwise position from its zero or original position.

For the penny ejection cylinder 28, since none of its teeth were in operative position, this cylinder will remain as before, at a position 180 degrees in an anticlockwise direc tion from its original or zero position.

The cylinders are now set ready to perform the correct eXpulsions; and in the last operation just described, when the ejection cylinders are rotated in a clockwise direction it is necessary that the contact latches or hooks 56 should be lo vered out of operating position. This is shown in Figures 6 and 7 as accomplished as follows. A, suitable cam 69 held fixed relatively to the shaft 5 and'master drum 6 acts upon the T shaped member 7 O to lower it during the clockwise movement of the ejection cylinders, though not necessary this action may occur during the anticlockwise movement oi the cylinders. This T shaped member 70 terminates along its lower edge in projecting tips 72 (Figure 7), these tips so located as to engage with the several hooks 56; and thus during the setting of the ejection cylinders, all ejection hooks 56 are lowered and out 01 contact with the contacts 48 of all the ejection cylinders, allowing them to -freely rotate.

Crank 1? is now rotatedthree times in a clockwise direction and through the action of its wide faced pinions and '34, engaging with the gears 29 and 29", will complete the rotation of the ejection cylinders 28 and 3'? back to their zero position, and the correct change, one dime and one nickel will be ejected.

Referring to Figure 8 as soon as crank 47 and shaft 31 begin to turn the pinion driving its gear 84 and. the shaft 85, which carries the cam or warped disk 86 which rotates in a grooved disk 87, will cause the shaft 31 to slide to the right as shown which will carry the pinions 30 and 34; into ntiesh withtheir corresponding gears and 29, and by continued rotation of 47 these gears 29 and 29 with their corresponding ejection cylinders will be rotatecl until the point 33 shown in the gear 29 in Figure 3 reachesthe pinion 26 when no further rotation takes place though the pinion continues to rotate. The point in the gear 29 is so located that at the moment it reaches the pinion the corresponding ejection cylinder 28 will be at its zero position.

Referring now to Figure 12 the dimes cylinder has been rotated forward to 70 and backwz rd 60 leaving it set at 10.

The pennies cylinder has been rotated forward to and no backward rotation, leaving it set at Both cylimlers are now rotated backward to their zero position. All. ejection hooks are in line with each other and arranged as shown in Figure 2 that is held up in operating position by a small leaf spring 56, also the dollar and eagle cylinders remain at their zero position and will in this case remain ino wrative.

Consider now in the relative position the ejection hooks 56 and the cylinders contacts are as follows.

For the penny cylinder. the first or outside ejection hook is just opposite the figure .05 and the centerof its strip .01.

The second hook is opposite .05 center of its strip .01.

The third hook is opposite .05 and center of its s rip or line of contacts For the dime cylinder, for the case described above, the first or outside ejection hook is opposite .10 in the .05 row of contacts; the second hook opposite .10 in its row of .10; the third hook opposite .10 in its rod or .10; the fourth hook is opposite .10 in its rod of .25; and the fifth hook is opposite .10 in its row of .50.

Now when the penny cylinder rotation is continued on from this setting, rotating from .05 back to zero, it will be seen that all. three hooks, are up and in position to engage each its contact. The first to engage will be the third or .05 (nickel), which is a master ejector bar acting on the drum 28, and the rotation of said drum 28 carries the master bar forward to operate the toggle joint and 61 (Figure 2). 61, (i3 and 66 are secured together, also for each of the penny hooks there is similar lug 66 fast on the shaft 63. t will be seen that by the forward movement of the master bar 58, the shaft 68 is rotated, and all the lugs 66, in the penny section, are low cred against their ejection hooks 56 forcing them down and out of action by a direct and positive moven'ient, excepting only in this case of the hook on the acting master bar, as is seen, the hook in this case has passed on and out of reach before its lug (:6 has had time to act.

Taking now the dime cylinder. for the ex ample as above described, and in the same way as in the penny cylinder, the five hooks of this set will all be in line opposite the figures .10. In this case however only the first three hooks are up in operative position where they can engage with their oncoming contacts. The fourth and fifth hooks. .25 and .50 also in line with the fig me .10 are pressed up against the filled in surface as shown in solid black, and can and at only slide along this surface to drop off into operating position at the end of the rotation to zero. It will be seen that for the first hook .05 row, there .is no contact for it to engage the cylinder rotates from 10 to zero. The san'ie is true of the third hook in .10 row. Only the second hook, in the first .10 row will be engaged by a contact and will operate and eject a ten cent piece.

Pi e therefore receive, in this sample transaction of out of tendered, one dime from the dime cylinder and one nickel the penny cylinder. The dollar and c cylinders with their index buttons 11 remaining at zero, receive no setting in either .ction by the rotation of the crank 7 nor the crank 4:7.

As may be seen in Figure 2 the actual ejection of a piece of money is by a straight line direct push of the ejection bars, the striking end being arrangedto eject one piece of money at a time through a suitable slot. in the bottom of the money till, the same bar may operate several times during one operation. but ejects but one coin for each forward movement.

t aid objection bars are brought back to their first or normal position by the action of the springs i As an 63111111218 of a more involved case requiring the action of the carry over as also the cutting out of the lower denomination.

Taking the case of a purchase of $1.67 and the payn'ient of $6.50 the operation is as follows.

First, set the button 11 in the dollar rod at 6, the button for dimes at 5, and the button for pennies at zero.

Second, make one complete clockwise rotation of the crank 7.

Third, reset button in dollar row to 1, in dime row to 6, and in penny row to 7.

Fourth, make onecomplete rotation in anticlockwise, direction of crank 7.

Fifth, make three clockwise rotations of crank 17, and there will be ejected, two bills, one 50 piece, one 25 piece, one piece and three pennies.

The mechanical movements are as follows In the second operation :-As explained in the simple example, the ejection hooks 50 for the. penny cylinder will be in alignment with its Zero figure, and this cylinder will. not be rotated; the hooks 56 for the dime cylinder are opposite the figure .50 and for the dollar cylinder are opposite the figure 6.

In the fourth operation :The penny cylinder will be rotated backward from zero to .0908-0706.05-0 t to 03, that is seven-tenths of a rotation and its three hooks register With .03.

Now as the rotation of the master drum 6 backward or anti-clockwise will rotate.

its gear 16 forward or clockwise (Figure 3) the position of the boss or tooth 17 is in such relation to. the flaring guide plate 19 that, any rotation of one tooth or more of 17 in an anticlockwise direction, the tooth 17 contacts with and raises 19 into operative position.

As already explained is a loose tooth, out of alignment with its series, but always projecting. The position and form of' 19 is such that when raised the tooth 13 of the next higher series (that is the dime drum) will sweep against its flanged side and be forced over and into line during the instant of 13 passing its gear 16; or in other words the passing of boss 17 under or across 19. will add one tooth or space to the rotation of its next higher series.

neously, and there will be no, interference. Also tooth 13 once past the guide 19 is returned to its normal position by the spring and guide 19 is also returned to normal position by the knob 20 which presses it down to. the position shown in Figure 3.

The cylinder for di1nesThis cylinder will be rotated backward as follows. By operation second it was advanced 5 teeth or to register with .50 (Figure 12). of its teeth were set out into operating posi tion, also its tooth 13 was forced over and into operating position at the moment of passing. So. this cylinder was rotated backward. 6 plus 1, or 7 teeth; seven divisions back from .50 its first position will leave it placed with its hooks opposite its figure .80 but in returning backward past the zero the guide 19 of this series is also raised by the passage of its boss 17 and a carryover set for the next or dollar cylinder.

The cylinder for dollars, first rotated six points forward is, in this operation (second) returned one point backward by its projecting movable tooth and also one point by its tooth 13 as operated by the carry over of the dime series.

1V e have then the three ejection hooks of the dollar cylinder in register with the fi ure 4.

By the fifth operation, the three hooks of the penny cylinder were. by the operation four, left in registry with .03; the hook at the left for nickels is held down by the long contact and does not operate. First the middle hook is operated by contact with the contact of .01 then the outer hook on the right is engaged by its advancing contact and operates, and then as the cylinders continue to rotate in their return to zero, the middle hook .01 is engaged by a second contact in line with it; and thus three pennies will be ejected.

Suppose 9 is called forWe would first get four pennies in succession and then a nickel, the act of throwing the nickel out would stop all further ejection of lower values as pennies.

By the fourth operation, the dime cylinder was set with its five hooks in line opposite its figure 80 (see Figure 12) and by the fifth operation the cylinder is rotated, as always, in a. clockwise direction, from its point of setting 80 down past .70 .60 -l50etc., to zero. N ow starting from 80 it is evident that ejection hooks for the first and fourth ejector-s will be first encountered by the advancing contacts, that means, as explained one nickel and one quarter will be ejected, the cylinder still advancing, the hook for the will be held down by the long contact and its master bar held from returning to an operative position, just as long as the length of the long contact is passing. Note thatthis 25 bar in operating rendered the two tens and the nickel bar inoperative and that although contacts for each of the 10 pass their hooks that their ejector bars are inoperative and no money is ejected.

The advance of the cylinder reaching at a point slightly past the figure 60 the hook for the 25 bar drops thus releasing all hooks and ejectors, which will now be in an operative position.

The further rotation of the cylinder carries its contact .50 at once into engagement with its hook carrying forward ejection bar for which also is a master bar, and renders inoperative the ejectors for the 25, 10, 10 and 5 and holds them all in an inoperative position until the cylinder is rotated nearly LO its zero position.

the operation of this cylinder it will be seen that we have'received one 50 and one 25 and one 5 piece.

From the diagram Figure 12 it will be seen that any possible amount can be ejected as For change, 10 and 50, for 40 change, 10 plus 5 plus 25.

By the fourth operation the dollar cylinder was left set at 4. On the return of this cylinder to zero, first its middle or $2. hook engages, this hook, acting on a master bar cuts out the $1. ejector, but as seen in Figure 12 the hook for the $2; returns the amount the contact $1. is past its book, the hook for $2. is at once reengaged by a second delayed action or long contact again causing to operate its ejector and again cut ting out the $1. ejector until reaching the zero position; and by this operation we have ejected two $2. bills (in their holders as described.)

If $7. was calledfor we would get and 555. If $6. was called for we would get $1. and S55. If $5. was called for we would get $5. and $0. and $0. If $9. was called for we would get $5. and $2. and 5152.

Always and in each cylinder the smallest denominations are first eject-ed, followed by the higher and these higher cut out further ejection of all lower denominations.

In this example Where $6.50 has been tendered tor a purchase o't $1.67 the machine as described, has selected and ejected two bills, one 509- piece, one 2:11;- piece, one piece and three pennies.

In the same way and in the same manner an sum up to the capacity of the machine may be set for the amount received in pay ment and any smaller amount set for the purchase, and the machine will deliver the correct amount of change, giving in nearly all cases the smallest number of? pieces.
