Application January 18, 1934, Serial No. 707.086 5 Claims. {01. 271-57) can be delivered and the machine .automatically stopped.
A further improvement is the provision of cutoff which delays the stopping of the motor in order that the machine will not stop with a sheet in transit but will continue until the last sheet is free of the feeding device.
The invention also relates'to certain details of construction which will be hereinafter more fully described and finally embodied in the clauses of the claim.
The invention is illustrated in the accompanying drawings in which Figure 1 is a front view of an improved machine, embodying my invention. Figure 2 is a rear view of the machine shown in Figure 1. Figure 3 is a side view of the machine showing the left hand side. Figure 4 is a side view showing the right hand side with various parts broken away to more fully illustrate some of the parts in the inside of the machine. Figure 5 is a detail section of the means for guiding the rear end of a wiper that feeds the sheets from the stack. Figure 6 is a diagrammatic view of the various parts that require electrical connection and of the circuits that connect them. Figure 7 is a perspective view of the pad that feeds the sheets successively from the stack.
The machine is preferably portable. It comprises a base ill on which the casing l I is mounted, the casing enclosing a frame I2 011 which the major part of the delivery mechanism is mounted. On the frame I2 is the holder H for supporting the stack S of sheets of paper or other material. In the present showing the machine is one for counting and delivering paper money. The stack S of sheets rest on flanges l3 on the ends and. at the rear of holder H leaving the bottom of the holder practically open for the positive engagement of the bottom sheet by the wiper or feeder W. The stack of sheets is held flat by a weight or follower M which follower has an additional function in acting to close a circuit to cause the machine to halt when the last sheet leaves the holder. This functioning will be described later.
Under the open bottom of the holder H, I place a means for successively removing a sheet at a time from the bottom of the stack. The preferred form comprises a wiper or feeder W secured .at
one end to the drum D fastened on the shaft S. 5
The wiper is in the form of a cushion I5 preferably of soft rubber with a cover [6 of rubber or the like slightly roughened or provided with minute pebbles, the face I! being the part that engages the sheets. The pad is provided with a recess I5 to clear the flange l3 at the rear of the holder H. The pad, otherwise extends virtually across the whole width of the holder. The front edge of the wiper is tapered or inclined as at 18 to engage the bottom sheet gradually in order that the whole face I! of the wiper engages the bottom sheet at practically the same time. It will be noted also that the centre of the drum D is under the rear part of the holder H which prevents the wiper from coming up 20 against the stack until the whole wiper is ready to engage the stack. The rear end of the wiper is guided by cam slots IS in which are projections which are secured to the wiper. The form shown comprises the shaft 20 extending across the wiper with its ends provided with the rollers 2|. Therollers are in the cam l9 and not only guide the rear end of the wiper up against the stack when the front edge of the wiper engages the stack but prevents any excess swing of the wiper when it is at the bottom of the drum. The cam slot I9 is wider at the part that extends forwardly under the drum as at 22. The wiper is thus relieved in its contact with the curved wall 23 that extends from the bottom of the holder H concentric to the centre of the drum D for the major part of its length but is tangential at the lower part 24. The wall 23 extends downward beyond 24 to form the wall 25 to provide the rear wall of a reservoir that receives the sheets in a new stack at 26. The front wall 21 of the reservoir can swing outwardly on the pivot 28 and is held in place by a spring 29. The base H) is depressed at 30 and the front walls 21 of the reservoir is cut out at 3|. This allows the fingers .and thumb to be placed over and under the stack 26 to withdraw it without disturbing it as the wall 21 readily swings outwardly until the stack clears it and then falls back into place.
Near each end of the holder H on the rear face is a cut out portion 32 which receives a soft rubber finger 33. These fingers are provided with bent and flexible ends 34 which extend from the bottom of the rear wall 35 of the holder and are stiff enough to resist the passage of a sheet that attempts to follow the bottom sheet out of the hopper. These fingers insure that only one sheet at a time follows the pad or wiper W around the drum to the reservoir. The rubber fingers are shown as secured by the clips 38 held in place against the fingers by the bolts 37. These fingers may be installed in any number but for paper money, two, one near each end, are found sufficient.
The shaft S is operated from the motor W, usually by the worm 38 and the worm-gear 39. The shaft is provided with a sleeve 46 insulated from the shaft and having a strip 4| of insulation on its face. The sleeve acts as a connector for two terminal posts 42 and 43 except when the insulation 4| is in line with the contacts 42 and 43. This device acts in conjunction with another circuit and is for the purpose of carrying the current to the motor after the motor is otherwise shut off which insures the complete delivery of the last sheet instead of stopping the motor with a sheet still between the wiper and the wall 23.
The motor H is equipped with a brake 44 which is normally operative for stopping the motor but which is held' inoperative by the magnet 45 which is in circuit with the motor and the con tacts 42 and 43. This insures the stopping of the motor when the insulated strip 4| bridges the two contacts 42 and 43 and the other circuit to the motor has been broken by other mechanism. This brake insures the stopping of the feeding device or wiper before it engages another sheet but only after the previous sheet has been completely delivered. The circuits controlling these various devices will be described later.
The machine is equipped with a mechanism for automatically delivering a pre-determined number of sheets after which the delivery mechanism of the machine stops. The mechanism for halting the machine is arranged to selectively control the'motor and to indicate the total number of sheets fed. The mechanism as shown comprises a pinion 46 on the main shaft 3 which pinion operates an idle gear 41 on a shaft 48 which turns a pinion 49 which operates a.- large gear 50. The large gear 50 is fastened on a shaft 5|. The gearing hasa ratio that causes one hundred revolutions of the wiper and shaft S to rotate the shaft 5| once. The shaft 5| is provided with: a disc 52 on the face of which are numerals from to I00 which can be seen through the opening 53 in the casing of the machine. The disc 52' also actuates' a counter 54, the shaft of which counter has a tooth 55 operated by a tooth 56 on the disc 52 which registers each hundred sheets counted. By reading the counter and disc the total hundreds on the counter and fraction of hundreds on the disc can be ascertained at any time.
On the shaft 5| are one or more trip-plates 51 which are provided on their peripheries with notches 58. These plates 51 are used for regulating the number of sheets to be delivered. For instance, one plate has one notch which is used for actuating the motor stopping mechanism after one revolution of the plate which insures the feeding of one hundred sheets. One plate has say, ten notches and this" controls the machine to feed only ten sheets at a time. Actuated by each of the trip-plates 51 is a contact switch comprising a terminal 59 of spring metal and a second terminal 60 of spring metal which contacts all have a normal tendency to spring apart as the contact 59 is limited in its movement by the stop 6|. When a plate actuating a contact in circuit revolves to bring a notch 58 opposite the end of the contact 60 which is preferably provided with a small roller the end of the contact springs into the notch, the contacts spring apart and the circuit is broken. This cuts off this circuit from the motor which, however, is operated through another circuit until the last sheet is fully delivered but is then cut off through the operation of contacts" and 43 being engaged by the insulated strip 4|. The trip-plate delivering ten sheets for each partial rotation has ten notches 58' assuming a complete rotation for 100 sheets, the plate regulating the machine for twenty-five sheets has four notches and the other accordingly.
The selection of trip-plate is made by means of an indicating switch 62 comprising a rotatable knob 63 with a' switch arm 64 adapted for engagement with the buttons 65. The switch arm 64 is mounted on the shaft 66 which forms a binding post 61 for a wire and the buttons 65 are each connected by the terminal 68 with a wire. To insure the secure positioning of the switch the index plate 69 is arranged on the shaft 66 and has indentations 10 into which the end of the arm fits to hold the index plate and shaft in place. The index plate is yieldingly held in position by the spring 12.
A device for cutting the current from the motor when the last sheet in the hopper H leaves the hopper utilizes the follower l4 which includes material that will electrically connect the two terminals 13 and 14 under the stack. The terminals are preferably on spring arms which bear up against the bottom of the stack S. The stack acts as an insulating medium but when the last sheet leaves the stack the follower |4 connects the two terminals 13 and 14. The circuit of which these terminals are a part will be described hereinafter and includes a magnet 15 which when energized pulls down an armature 16 on an arm 11'. The arm 11 is normally held up by a spring 18 fastened to a support such as the arm 19 which also acts to pivot the arm 11 as at 80. The arm carries two contacts 8| and 82, the switch contact 8| cooperating with the fixed contact 83 and the contact 82 co-operating with the contact 84. When the contacts 8| and 82 are in co'ntact to complete the circuit the armature is lifted but allows one end to rest on the core 85 of the magnet. This is due to the armature 16 being pivoted as at 86 to the arm 11 near one end of the armature. This arrangement facilitates the attraction of the armature by the core.
A safety switch 81 is installed in the main circuit for easy shutting off of the current when the machine is being charged without pulling out the plug fitting in the socket 88.
It will be obvious that when the shaft S is stopped with the terminals 42 and 43 resting on the strip 4| of insulation a direction connection to the motor must be available which will, however, in turn, be shut off before the strip 4| shuts off the motor.
Such a circuit is controlled by a starting switch 89 having a push knob 90 on a lever 9| normally held open by a spring 92. When the switch knob 90 is pushed into the terminal 93 it connects the motor to start it and when the switch arm 64 is 70 on the continuous button marked C the magnet is energized which'hclds the armature 95 on the lever 9| to keep the circuit closed and it remains closed until either the trip-plates 51 or the follower |4 break this circuit through the switch ii. The lever BI has a connection 96 at the top for completion of the circuit.
The operation of the machine is as follows:-
The follower It is raised and a stack of sheets, for instance paper money, is placed in the holder H and the follower M is replaced. The switch 81 is turned on and the machine is ready for operation. The motor always stops with the shaft S in a position that brings the insulation 4| opposite the contacts 42 and 43 which precludes the starting of the motor through these contacts. Therefore, to start the machine the switch knob is pushed in. On the diagram in Figure 6 it will be seen that this connects the two main wires 5? and 95 with the motor M through wires 59, Edii, switch 82-8 5 wires IUI and I02 to the motor and from the switch through wire I03, switch 8i-83, wires IM and I05 to contact 42 and thus to the main wire 98 which completes the circuit to the motor. The motor starts as the circuit also releases the brake through magnet 45.
The shaft S rotates the drum and carries the wiper W around to engage the bottom of the stack S and remove a sheet at every revolution and tally the number on the indicators visible through the opening 53. This is assuming that the trip-plate marked 0 for continuous feeding has been placed in circuit with the switch arm 5 5. In this case the wire Hit carriesthe current to the magnet 5 of the switch 89 and then through wire it? to wire I53 and also from the switch arm 64 through wire I58 to wire I95. When the last sheet leaves the hopper the follower it connects the terminals I3 and M. This carries current from the-main wire 97 through wire we, contact I3, follower I4, contact I i, wire lit? to the magnet 15 and then through wire III to main wire 58. When the magnet I5 is energized it pulls the arm ll! down and this opens the switches at and 82 which cut off the motor from these connections. At this time a sheet is in transit between the wiper W and the wall' 23. This necessitates the finish of the delivery. To accomplish this the current still flows through wire 58, contact 52, sleeve 45, contact 43, wire N32 to the motor and through main wire 5?. When the insulation it, however, bridges the contacts s2 and is which is at the time the wiper W releases the last sheet to the reservoir on the new stack 25, this current is cut off and the motor stops.
When a pre-determined number of sheets are I required, say 10 sheets, the switch arm 64 is placed on button marked I5 and this places the switch 62 in circuit with the wire H2, contacts and 5E and wire I it which connects with wire Hi5 and then through the main wire 93. The current also passes through wire 158 to wire I05, switch 32, wires HlI, I52 through the motor to wire 9?. This circuit to the motor is broken when the contacts se and 66 are separated by allowing the end of contact 55 to enter a notch 53 in the trip-plate 5i above these contacts. The motor, however, continues delivery until shut off by the insulated strip M as before.
It will be noted that a signal light H4 is connected to the main wire 91 by wire I I5 and to wire IIG by wire H5. This is for the purpose of lighting the light when the magnet I5 is energized to stop the motor by opening the switches BI and 82. The lighting of this light indicates that the machine has stopped. The operator then opens switch 87 and starts the machine again by pushing the starting button 90.
It will be evident that the parts can be altered in proportion and form and variously disposed without departing from the scope of my invention.
