INVENTOR BFA/JAA/l/N COOPER TTORNEY Patented Jan. 23, 1945 UNITED STATES PATENT OFFICE PAPER FEED DEVICE Benjamin Cooper, Jersey City, N. Application February 14, 1941, Serial No. 378,847

(Cl. 27h-2.4)

Claims.

This invention relates to paper feed devices. It is particularly directed to registers, accounting, or calculating machines wherein a strip sheet is used for receiving the successive impressions of printing wheels as the strip is advanced.

The present invention may be readily adapted to a registering system for checking tolls over highways, bridges, or tunnels. In such a checking system accounting costs are materially reduced when an elongated str ip sheet having a plurality of successive, preprinted ledger forms is used in the register. The preprinted forms are separated by transverse perforations and may be ruled oil into columns with appropriate headings printed thereabove. The lower portion of the forms may bear suitable descriptive wording and blank spaces for the entry of totals, money collected, and collectors signature or number.

When a collector goes on duty, one of the preprinted forms is placed in printing position in the register. Most registers are provided with timing means to give an hourly print of the accumulated data of the register. Thus during the entire time a collector is on duty hourly prints are made on the form in the proper columns. When the collector goes off dutyI the device hereinafter disclosed is actuated to advance the complete printed record of all transactions to position where the collector may sever the same from the strip sheet. The advance of the completed form by the hereinafter disclosed device will move into printing position another preprinted form for use during the next shift by another collector.

'I'he data impressed form is taken by the collector and left at the administration oiiice where the data is computed and the computations ens tered on the form. The forms may then be led away in loose leaf binders as ledger books. Thus a separate and complete record is had of each collector, and the need for transferring data.

from recording tapes is entirely eliminated.

It is an object of this invention to provide a paper advance device having means tofadvance an elongated strip sheet of preprinted forms a predetermined distance'so that a succeeding form of said sheet is brought into printing position while the impressed printed form is advanced to a position where it may be readily severed from the elongated sheet.

It is a further object of this invention to provide a paper feed device of the character described comprising mechanism controlled by means on the strip sheet of preprinted forms to limit the extent of advance of the elongated sheet.

It is another object of this invention to provide a paper feed device of the character described having means to advance the elongated sheet predetermined lengths under the control of an operator, and additional means under the control of the printing mechanism to automatically advance the sheet after each printing operation one line' to permit a, succeeding printing operation.

Still another object of this vinvention is to provide in a paper feed device of the character described means to prevent the advance of a preprinted form on said strip before said preprinted form receives at least one impression from the printing wheels.

Still a, further object of this invention is to provide a highly improved, compact, and rugged device of the character described which shall be easy to operate, relatively inexpensive to manufacture, positive in action, which shall have a large variety of applications, and yet be practical and eiiicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in' features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

Referring now in detail to the drawings, I0 designates a register embodyingthe invention, comprising a frame Il having two parallel side walls I2 and I3, and a horizontal base plate Il fixed lto said side walls above the lower edges thereof.

The side wens l2 and la are provided wan through openings l5 at .their upper edges to facilitate handling of the register l0. Integral .with

the inner surface of side wall I3, and below the through opening I is a. boss I6 having a vertical portion I1 and two horizontal strengthening ribs I8. Integral with the inner surface of side wall I2 and in horizontal alignment with boss |6, is a similar boss I9 having a vertical portion 20. For the purposes hereinafter described there is fixed to the vertical portions I1 and 20 of the bosses I6 and I9, as by screws 2|, a mounting bar 22 disposed in a vertical plane whose upper and lower edges are parallel with the base plate |4.

Side wall I3 is further provided near its front edge with a through opening 23 and with a through opening 24, below and in alignment with the opening 23. Fixed in the through opening 23. as by screws 25, is a bearing 26. Fixed to the outer surface of said side wall as by screws 21, is a gear guard 28 concentric with the opening 23 and enclosing said opening and also the opening 24. Fixed to the inner surface of wall I2 is a bearing 29 in horizontal alignment with the bearing 26. Integral with the inner surface of side wall I2 is a stud pin 30, and a boss 3| (Figs. 1 and 4).

For the purposes hereinafter described, there is Journaled in bearing 29, and through the bearing 26, a horizontal shaft 32, extending slightly beyond the gear guard 28. Fixed to said shaft, as by screws 33,.at spaced intervals, are a plurality of knurled rollers 34. Fixed to said shaft near side wall I3, as by screws 35 is knurled roller 36, having a peripheral groove 31 about its center portion. Fixed to said shaft near side wall I2 is a. ratchet wheel 38.

Fixed to the mounting bar 22, as by screws 39, are a plurality of shouldered members 40, each provided with two depending shoulders 4 I. Fixed in the lower ends of each pair of shoulders 4| are horizontal, concentric shafts 42. Rotatably mounted on each of said shafts are a plurality of digit printing wheels 43 adapted to be actuated by a pawl swing 44 to advance said digit wheels. The pawl swings are actuated by electromagnetic counters (not shown) such as disclosed in my patent for Electromagnetic counter units, No. 2,185,724, issued January 2, 1940.

Journaled in side walls I2 and I3, near the upper and rear edges of said walls is a horizontal shaft 62. Mounted on said shaft is a spool 53 carrying a paper roll 54 of recording paper P.

Fixed to the side walls I2 and I3 is a paper guide 55 carrying said paper downwardly and forwardly under the digit wheels 43 and over the knurled rollers 34. Fixed to the upper plate of said paper guide, adjacent to each of the side walls I2 and I3, and between each set of digit wheels 43, is a forwardly extending finger 55a supporting a printing ribbon R. The printing ribbon is carried underneath the digit printing wheels 43 and above the paper P, and over rollers 55h. The printing ribbon R is adapted to be advanced after each printing operation by a ribbon advancing mechanism (not shown) such as for example disclosed in my patent for Electromagnetic printing counters, No. 2,115,410, April 26,

The paper P is a strip or web divided into sections which may carry printed forms. Between the printed sections are transverse lines of perforations 92 to facilitate severing of said sections from strip proper. Each section is further provided with a marginal through opening 9|, the openings 9| being in alignment (Fig. 6). The openings 9| may be in the form of longitudinal slots for the purpose hereinafter appearing.

Means is now provided to automatically advance the paper P a predetermined distance, the extent of advance being under the control of the paper itself.

There is further fixed on mounting bar 22, ad jacent wall I3, as by screws 94, a bracket 93, provided with a depending shoulder 95. Pivoted to the lower end of shoulder 95, as at 96, is a lever 91 having a forwardly extending arm 98, a rearwardly extending arm 99, and an upwardly extendingarm |00. Arms 98 and 99 are provided with shoulder portions |0| and |02, respectively. Arm |00 is provided at its outer end with an in.. sulated pin |01.

Fixed to shoulder |0| of arm 98, as by pin |03, is a roller |04 aligned with the peripheral groove 31 of the knurled roller 36, and adapted to ride over the surface of the paper P on a, line with the through openings 9|. Roller |04 is held against the surface of paper P by a light coil tension spring |05 connected at one end to shoulder |02 and at its other end to a pin I 06 in member 93. Spring |05 is sufficiently charged to rotate lever 91 in a clockwise direction about the pivot 96 (Fig. 3) when an opening 9| in the paper P is moved under the roller |04, permitting roller` |04 to engage the peripheral groove 31.

For the purpose hereinafter appearing there is fixed to member 93 two normally closed insulated spring fingers |08 and |09. Spring finger |09 is engaged by the insulated pin |01 and is adapted to be moved thereby out of engagement with spring finger |08 upon rotation of lever 91 in the manner hereinabove described, when the roller |04 drops through an opening 9| into groove 31.

Fixed to the outer end of shaft 32 is a ratchet ||0. Rotatably mounted on said shaft between the wall I3 and gear guard 28 is a gear I I. Fixed thereto is a. plate I I2'. Fixed to plate I I2 is a boss ||3 to which there is pivoted a pawl ||4. Pawl ||4 is adapted to engage the teeth of ratchet I0 and is held in engagement therewith by a torsion spring I I5 mounted on said boss and fixed to said pawl and to said plate.

Fixed to the inner surface of wall I3, as by screws ||6, is an electric motor II1, having a horizontal drive shaft ||8, one end of -which passes through the opening 24 in said wall, the other end extending toward side wall I2. Fixed to the end of said shaft adjacent to the outer surface of Wall I3 is a pinion shaft ||9 carrying a pinion I 20 adapted to mesh with the teeth of gear III. Fixed to the other end of shaft I8 adjacent to said motor is a metal washer |2I. Rotatably mounted on said shaft are two fiber washers |22 having a star ratchet |23 interposed between them; and a metal washer |24. Fixed to the outer end of shaft I I8, as by screw |25, is a metal washer |26. Placed about shaft ||8 and abutting washers |26 and |24 is a coil compression spring |21 urging the washers |24 and |22 and the Star ratchet |23 against the fixed washer |2I.

Motor ||1 is adapted to rotate its drive shaft in a clockwise direction, rotating pinion |20 in the same direction (Fig. 2). The gear III is thus rotated in a counterclockwise direction, rotating the plate I2 and its pawl I I4. Pawl I4 will thus engage the teeth of ratchet II 0, rotating said ratchet in a counterclockwise direction. Shaft 32 will thus be rotated in a counterclockwise direction to advance the paper P.

Fixed to motor ||1, as by screws |28, is a vertical mounting plate |29. Fixed to said mounting plate, as by screws I3I, is a horizontal support |33. Mounted on said support is a relay |34 having a coil |35 and an armature |36 pivoted to the support, as at |31. Fixed to and extending through said armature is an insulated pin |31. Mounted on the support |33 and extending upwardly therefrom are two pairs of normally closed insulated spring contact fingers |33 and |39; and |4|, the former finger being engaged by pin |31. Spring fingers |39 and |4| are interconnected at their outer ends by an insulated block |42 to move together. When armature 36 is in initial position, as shown in Fig. 3, pin |31 will hold spring fingers |38, |39, and |40, |4| open, permitting said fingers to close upon energization of the relay |34.

Pivoted to mounting plate |29, as at |43, in alignment with the star ratchet |23, is a pawl |44 having a depending arm |45, and an upwardly extending arm |46 adapted to engage a tooth of said star ratchet. Arm is connected to mounting plate |29 by a coil tension spring |41 connected to a pin |48 in said plate, said spring urges pawl |44 to rotate in a counterclockwise direction about 'its pivot |43 (Fig. 3). Depending arm |45 abuts the insulated pin |31, and due to the action of spring |41 tends to rotate armature |36 in a clockwise direction about its pivot |31.

When pawl |44 is in its initial position (Fig. 3), arm |46 engages a tooth of star ratchet |23. Upon energizing relay |34, armature |36 rotates in a counterclockwise direction, rotating pawl |44 in a clockwise direction to release the star ratchet from said pawl. Upon deenergization of said relay, spring |41 will return pawl |44 and armature |36 to their initial condition, pawl |44 again engaging one of the teeth of the star ratchet |23.

Referring now to Fig. 5, motor ||1 is connected at one terminal by wire |50 to plus power supply, and at the other terminal by wire |5| to the springy finger |40. Spring iinger |4| is connected by wire |52 to minus power supply. Spring nger |38 is connected by wire |53 to one end of coil 35 of the relay |34 and by wires |53 and |54 to one terminal of a push-button |55, the other terminal of said push-button being connected by wire |56 to plus power supply. Spring finger |39 is connected by wire |51 to spring finger |09. Spring nger |03 ls connected by wire |56 to wire |56 to plus power supply. Coil |35 of the relay |34 has one end connected by wire |54 to push-button |55 and the other end connected by wire |59 to minus power supply.

The operation of the automatic paper advance will now be described.

When push-button |55 is closed, relay |34 becomes energized, the circuit being from plus power supply through wire |56, push-button ,|55, Wire |54, coil |35, wire |59, to minus power supply. Relay |34 closes its associated switches, switch ISS-|39 closing an energizing circuit for coil |95 to hold said relay energized after the push-button is released, the circuit being from minus power supply through wire |59, coil |35, wire |53, switch |39-|39, wire,|51, switch |06|09, Wire |58 to plus power supply.

By closing switch |40-|4|, motor ||1 isoperated, the circuit being from plus power supply through wire |50, motor ||1, wire |5|, switch M40-|41, wire |52 to minus power supply. In energizing relay |34, armature |36 will pivot pawl |44 in a clockwise direction, Fig. 3, to disengage said pawl from the star ratchet |23. Motor |1 will thus be able to rotate, rotating shaft 32 to advance the paper P in the manner hereinabove described.

In advancing the paper P, an opening 9| in said paper will slide under the roller |04 of the lever 91, permitting said roller to ride in the peripheral notch 31 of the knurled roller 36. Lever 91 will thus be rotated in a clockwise direction by its spring |05 (Fig. 3), opening the switch |06|09. By opening switch |08|09, the holding circuit for coil |35 is opened permitting relay |34 to beocome deenergized. Armature |36 of said relay will then be rotated in a clockwise direction about its pivot |31 by spring |41 (Fig. 3) to open the switches |38-A-I39 and |40|4|, while pawl |44 rotates in a counterclockwise direction to engage one of the teeth of star ratchet |23.

By opening A switch |40-|4|, the electrical power to motor ||1 is disconnected. Due to the inertia of the armature of said motor, shaft ||8 will continue to rotate after the power has been shut o3. This rotation is quickly checked by the engagement of pawl |44 and the star ratchet |23 and the friction generated |between the ber washer |22 and the metal Washer 2| fixed to said shaft, the advance of the paper being halted as roller 04 reaches the end of opening 9|.

While the paper advance mechanism herein disclosed has beenv shown as being operative by a push-button, a lock switch might easily be substituted for the said push-button, thus permitting the recording tape and its recorded data to be kept under lock'and key; or a key identifier might be substituted for the said push-button such as disclosed in my application for a Key identifier, Serial Number 328,534, filed April 8, 1940, whereby the paper advance mechanism is actuated by the withdrawal of an identication key from the identier.

Means is provided to print against the digit printing wheels 43.

To this end there is journaled in the side walls |2 and 3 a horizontal shaft 45. Fixed to said shaft are a plurality of printing hammers 46, one printing hammer being in alignment with each set of digit wheels 43, and adapted to strike against the same upon rotation of shaft 45, paper and ribbon being interposed in the manner hereinbefore described.

Fixed to base plate I4, as by screws 41, is a solenoid 48, having an armature 49. Fixed to shaft 45, and in alignment with armature 49 is' an arm 50, connected by link 5| to the upper end of armature 49. Solenoid 48 may be energized by a timing device (not shown) to give periodic prints or it may be energized by a pushbutton or key in any of the well-known ways.

When solenoid 48 is energized armature 49 is moved downwardly, rotating arm 50 in a counterclockwise direction (Fig. 3). Shaft 45 is thus rotated in the same direction to rotate the printing hammers 46 against the printing wheels 43, the paper P and the ribbon R being interposed, to print on said paper.

Means is provided to automatically advance the paper P a line space after each printing operation.

To this end there is journaled in side walls I2 and I3, near the front edges thereof, a shaft 56 parallel to shaft 32 and slightly thereabove. Fixed to shaft 56 are a plurality of pressure members 51, one for each of the knurled rollers 34. Each of said pressure members comprises a yoke member 56 rotatably mounted on shaft 56, provided with two parallel arm 59 and 60, arm 60 being provided with a shoulder 6|; and a crosspiece 62. Rotatably mounted in the ends of arms 59 and 60 is a roller 63 registering with a knurled roller 34. Fixed to shaft 58 and between arms 59 and 68 is a dog 64 carrying a pin 65 adapted to be engaged by shoulder 6I. Mounted on shaft 56 is atorsion spring 66, one end of said spring being fixed to pin 65 and the other end being fastened to crosspiece 62 (Fig. '1).

Torsion springs 66 tend to rotate pressure member 51 in a counterclockwise direction (Fig. 7) pressing rollers 63 downwardly on knurled roller 34 to hold the paper P, the pins 65 being free of shoulders 6I.

Pivotly mounted on shaft 32, adjacent ratchet 38 is a pawl swing 81, having a depending arm 68. Pivotly mounted on arm 68, as at 69, is an actuating pawl 10, held in engagement with the teeth of ratchet 38 by a leaf spring 1I. Pivotly mounted on boss 3l on side wall I2 is a stop pawl 12 held in engagement with the teeth of ratchet 38 by a torsion spring 13 mounted on said boss and xed to said wall at one end and to said stop pawl at the other.

Fixed to shaft 45, in alignment with pawl swing 81, is an arm 14 carrying a pin 15, interconnected to frame I I by a coil tension spring 16. The lower end of arm 14 is connected to the pawl swing 61 by link 11.

Each time solenoid 48 is energized to rotate shaft 45 for bringing the printing hammers 46 into printing position, arm 14 is rotated in a counterclockwise direction, Fig. 3, rotating the pawl swing 61 in the same direction. Ratchet 38 is held by the stop wall 12 thus permitting pawl to slide over a tooth of said ratchet. After the printing operation, tension spring 18 rotates arm 14, and the printing hammers 46, in a clockwise direction to initial position. Pawl swing 61 is thus rotated in the same direction by link 11, the actuating pawl 10 engaging the ratchet wheel 38 and rotating it in a clockwise direction. Thus shaft 32 is rotated in the same direction, rotating the knurled rollers 34. Due to the pressure of rollers 83 on the knurled rollers 34 the paper P is moved one line space forwardtoward the front of the register I0.

Means is provided to release the pressure members 61 to free the paper P from the rollers 63 and the knurled rollers 34.

To this end there is iixed to shaft 56 adjacent wall I2, as by set screw 18, a lever arm 19, having a shoulder 80 adjacent wall I2 and a thumb plate 8| at its upper end, Pivoted to said arm adjacent wall I2, as at 82, is a bell crank 83 having an arm 84, provided with a notch 85; and an arm 86, provided with a pin 81. Bell crank 83 is further connected to arm 19 by a coil tension spring 88 connected to said bell crank and to said arm, as at 89.

When lever arm 19 is in normal position, pin 30 on wall I2 is engaged by notch 85, as shown in Flg. 4. To release the pressure members 51, bell crank 83 is rotated, by lifting pin 81 and rotating bell crank 83 in a counterclockwise direction about its pivot 82 to free notch 85 from the pin 38. Lever arm 19 may now be rotated in a counterclockwise direction (Fig. 4) until the shoulder of said arm engages a pin 90 in wall I2, Arm 19 will rotate shaft 56 in a counterclockwise direction, rotating the dogs 84 in the same direction. Pins 85 thus engage the shoulders BI of arms 60, rotating the pressure members 51, to lift the rollers 63 from the knurled rollers 34.

Spring 88 will rotate the bell crank 83 in a clockwise direction about its pivot 82 (Fig. 4) thus bringing the lower edge of arm 84 in contact with pin 38. Due to the pressure of said spring and the sloping edge of arm 84 lever arm 19 will remain in its release position with shoulder engaging the pin 98. To reestablish pressure on the paper P and rollers 34, lever arm 18 is rotated in a clockwise direction (Fig. 4), arm

84 sliding over pin 30 until the pin again engages4 the notch 85.

It will be thus seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
