a lication 'file'd April 30,

This invention relates to improvements in machines used for printing values and particularly to machines of the kind known as check writing -or check printi ng-ma chines, by which the amounts are-filled in on bank checks,'vo-uchers, etc. f

An object of. the invention is to provide improved means for fillingin, the dateand' amount of a check. Another object isthe provision of improved-means for aligning the printing wheels of'su'ch a machine. Another object'is the provision'flof improved feed mechanism for the ink ribbon- Otherobjects and advantages will hereinafter appear.

The invention consists in the novelficonstruction and combination of parts; as set forth in the appended claims- In the accompanying drawings:

P

NEW JERSEY, A eoaromirion or ew Two sets of spring detent pawls 25 and 26 (Figs. 3 and 4) are provided, as shown. The pawls 25 engage with the type wheel gear members 16 of type set 1 and are constantly active, while the detent pawls 26 engage with the type wheel gears 23 of type set 3 and are automatically released after a printing operation as will be more fully described later.

Operating means The desired value having been set up by the value-inserting levers 10 (Fig. 1) the operator depresses the operating key button 29 to set in motion the printing and automatic ink ribbon feed mechanisms as will hereinafter be described.

An operating lever 30 (Fig. 5) pivotally fastened to the framing of the machine at 31 has pivotally mounted thereon a pawl 32 one' end of which terminates in a recess embracing a pin 33, fast to a lever 34 fulcrumed in the framing at 35. The pawl 32 is normally held as shown in Fig. 5 by means of lug 36, and spring 37. r

The depression of the operating key button 29 causes the lever 30, rocking about point 31, to carry the pawl32 in a clockwise direction and through engagement with the pin 33 rock with it (against the tension of spring 38) the lever 34. The upper end of lever 34 forms a hook 65 and engages with an arm of a clutch pawl member 39 (Figs. 5 and 6) pivotally fastened at 66 to a clutch disc 40. The clockwise movement of the lever 34 releases the clutch pawl member 39 allowing the same, under-the influence of spring 41,

to engage with a ratchet member 42. Ratchet member 42 and gear 43 are integral and loosely mounted upon the shaft 44, between the collar 45and the clutch disc 40, and are driven by the motor A through the pinion gear 46.

The clutch disc 40 is keved to the shaft 44- by pin 47 (Fig.6) and will, therefore, through engagement of pawl 39 with ratchet 42, transmit the power to the shaft 44. The printing is accomplished as follows: Fastto the shaft44 is a cam member 48 (Fig. 4) adapted to engage with a roller 49.

fast to a bell crank lever 50, supported on shaft 8, and rock said leverin a counter-clockwise direction about shaft 8. The other end of bell crank lever 50 engages, by means of an adjustable set screw 51, the striker rod 52 and drives the same upwards against the matrix bar support plate 53 to pivot the same about point 54'and bring the matrices 55 and 56 against their respective typewheels.

To insure against a reprint in the event that theoperator fails to release'the operating key button 29, an arm 61 (Fig. 5) is provided, pinned to the shaft 44 and having a pin 62 adapted to rise, during acycle of operat-ion, beneath the lug 36 of pawl 32 and rock same about point 63, to disengage-pin 33, whereupon lever 34, under the influence of spring 38, will return to normal position against the stop pin 64, and hook end 65 will lie in the path of movement of the extended arm 60 of clutch pawl member 39.

Upon the completion of one revolution of clutch disc 40, the arm 60 of clutch pawl member 39 will contact with hook end 65 of lever 34 and rock said pawl, against tension of spring 41, about point 66, out of engagement with the ratchet 42. Pin 67, fast to the clutch disc 40, contacting with the lower face of arm 60 ofpawl' 39, will stop the parts in their normal position against overthrow due to momentum.

A spring tensioned latch 68 is also provided to enterthe recess 69 of clutchplate 40 at the completion of a cycle, to prevent rebound of the parts due to their momentum and the tension of spring 41.

Automatic til/276 aligner and ink ribbon feed mechzmwn supported by means of a bracket 79 screwed to the framing of the machine. 7

Fast to the shaft 78 andsupported thereon is a bell crank lever 80, having pivotally mounted on one arm. at 81 a lever 82 having a stud 83 positioned to the'right of a tooth 84 of a rock lever 85', mounted upon the shaft 78, as shown in Fig. 7. Said rock lever 85has pivotally mounted thereon at 86 and 87 the levers 88 and 89 held in position by-means of a spring 109 and the pins 110 and 111.

The arm 90 of bell crank lever 80 has a. lug 91 positioned beneath a pin 92 fast to alever 93 mounted upon a shaft 94 (Figs. 3 and 7) extending transversely of the machine and having its other end loosely mounted in the framing at 95.

The shaft '94 passes beneath the rearwardly extending arms 96 (as shown'in Fig. 3 and indicated .by the dotted part in Fig. of detent pawls 26, (of type set 3) and holds said pawls out of engagement with the type wheel gears 23 against tension ofv spring 73.

During a cycle of operation the cam meniber 70, turning in a clockwise direction, will free the roller 71 and the springs 73 will rock the detent pawls 26 about shaft 7 into onga ment with the type wheel gears23 and the rearwardly extending arms 96 of said deteut pawls will rock the shaft 94 downwardly about point 95, whereupon lever 93, fast to shaft 94, will cause pin 92 to depress lug 91,

which the follower/('1 works. After cam has left follower 71, the crank movement of the pivoted end of link 116 about shaft 44, will bring the end wall of the slot into engagement with the follower and pull the same substantially into engagement with the low point of cam 70. Subsequent rotation of cam member '70 will cam the follower 1 1 to the larger periphery again and drive connecting link 72 upward thereby rocking the shaft 78, through arm ,T'Z, in a counter-clockwise direction, and lever fastto shaft '4" 8 will rock lever 82 in a comiter-clockwise direction, whereupon pin 83 engaging tooth 84 whereupon the movement, as previously deplunger 101 (Figof rock lever 85 will rock same with it and end 97 of lever 88 mounted thereon willen gage with the teeth of a ratchet member 98 fast to shaft 99, and rotate samein a clockwise direction.

The ink ribbon roller 100 (Figs. 2 and 4) is mounted at the right upon the shaft 99 and at the left side of themac-hine upon the spring Rotation of. ratchet member 98 will cause a lug 103, fast to shaft 99 and engaging a recess in the roller 100, to rotate said'roller and advance the ink ribbon from a similar roller 104 supported in similar manner at the rear of the machine.

0 When all of the ink ribbon is run off roller 104, the ribbon, being secured to said roller. will prevent further movement of roller 100 and cause the teeth of ratchet member 98 to prevent movement of the levers 88 and 85,

scribed, of lever 80 will cause pin 83 to cam over tooth 84 to a position to the leftof said tooth.

A cycle of operation and the subsequentrelease of roller 71 will cause a movement of the parts as previously described, but rock member 85, having been heldagainst return movement, will have positioned the end 105 l (Fig. 7) of lever 89 into engagement with the teeth of a ratchet wheel 106 having connection with theroller 104 through shaft 107 and lug 108 (Fig. 3) and thesprings 73 of detent pawls 26-will cause end 105 of lever 89 to rotate ratchet 106 in a counter-clockwise direction,

to feed the type ribbon back upon the roller 104, this feed continuing until the end of the ink ribbon is reached. At this time roller 100,

in preventingfurther movement of the ribbon, will hold roller. 104 and ratchet 106, thereby causing the teeth of said ratchet to prevent movement of levers 89 and 85 so that lever 80 will rock pin 83, fast to lever 82, back to its originalposition to the right of tooth 84, thus providinga continuous feed for the ink ribbon.

To keep the ink ribbon smooth and against the type wheels," friction drag members are provided, consistingof the washers 112 and 113 keyed to the bearings 114 and 115, to prevent turning, and held against the face of ratchet wheels 98 and 106 by the springs 118 and 119 as shown in Figs. 2 and 3. i
