Application 'fi eanovemter a, 1923. Serial No. 673,719.

To all whom it may concern:

Be it known that we, CHARLES B. MORGAN and ROBERT A. Cnoons, citizens of the United States, residing at Kansas City, in the countyof Jackson and State of Missouri, have invented certain new and useful Improvements in Writing Machines,.of which the following is a specification.

Our invention relates to machines where with bankchecks and other negotiable instrumentscan be written and one object is to provide a machine of this character embodying manually "controlled and. automatic type bar operating mechanism which is more rapid in action and can be used for writing a greater variety of instruments than is possible with the ordinary check-writing machines now in use. 7

Other objects will hereinafter appear, and

in order that the invention may be fully understood, reference will now be had to the accompanyingdrawings, in which:

Fig. 1 isa fragmentary side elevation of the machine, with some of the parts in section.

Fig. 2 is a fragmentary front elevation of the platen and associate parts.

Fig. 3 is a broken plan view of certain manual and power-controlled mechanism at the lower portion of the machine. 7 1 Fig. 4 is a'fragmentary front elevation of a type-lever guide and a type lever in operative relation to said guide.

Fig. 5 is a fragmentary side elevation of certain mechanism at the lower forward portion of the machine and embodying means for effecting rapid successive printing of a character.

Fig. 6 is afragmentary vertical section of certain mechanism at the lower front part of the machine, with some of the elements in different positions from that disclosed by Fig. 1. I

Fig. 7 is a detail perspective of a number of the elements at the lower forward'portion of the machine.

Fig. 8 is a brokendetail perspective of a bar employed in carrying out the invention.

In the drawings which, for simplicity, have been restricted to the novel features of the invention and their immediate associate parts, 6 designates a large paper feed roller provided with a rubber or other suitable covering 5 and carried at its ends byplates 3 provided with stub shafts 4 'journaled in bearings 4 at the upper portion of the car surface 9 and prevent its forward edge from passing between the rubber covering 5 and the platen 9. Small rollers-2 are provided to coact with the large roller 6 in feeding the paper, and stationary guides 8 and 10 are employed to retain the. paper against the roughened surface 9 of the platen 9.

The roughened surface 9" of the platen 9 coacts with the types 27 in mutilating the paper .as it is printed upon. Any desired number of typesmay be employed and each is carried bya holder 29 remcvably connected to theassociate type lever 30 by a pin 28, so that the type may be changed when desired.

Each type bar 30 is fulcrumed at 31 and has an angular slotted portion 32 through which a stud 33 projects from the upper end of a bell-crank 34 fulcrumed at 39 in a portion 38 of the frame 4".. Each bell-crank 34 is norone end on a pin 44 in the lower portion 44 of the frame 4.

The opposite end of the key lever 43 is provided with a key 46 which constitutes one member of a key board emjustabletypebar guide 1 is secured to the frame 4 by. screws 1*.

Referringnow to the inking mechanism and its actuating parts, 26 designates a supply pad or reservoir which is saturated with ink and arranged in the path of ink applicators '25, each of which is provided for supplying ink to the associate type 27 held .in engagement with the applicator by the coil spring 36 and intermediate parts. Each applicator 25 is secured to the lower end of a lever 21 by suitable means such as a screw 23 and is covered withfelt or other ink absorbing material 24. Each applicator lever 21 is fulcrumed at 19 to a forward upper portion 18 of the frame 4 and has a slotted 'mally held in raised position, Fig. 1, by a bodying any desired number keys. An adportion 20 extending between the forked terminal of an associate lever 13 fulcrumcd at 16 on a plate 17 secured to the frame portion 18. Each lever 13 is connected to the underlying key lever 43 by a rod and provi-ded with a pin 12 extending freely through the slot 20 of the associate lever 21 to actuate the same. Springs 11 are secured to the levers 13 by suitable means such as screws 14 and normally hold the applicator levers 21 in the position disclosed by Fig. 1.

The manual operation is accomplished as follows: Downward. pressure upon one of the keys 46 rocks the respective key lever 43 downwardly which in turn swings the lever 21 forwardly over the pad 26, as inclicated' by dotted lines Fig. 1, through the intermediacy of the connecting rod 15 and the lever 13. As the lever 21 swings forwardly it carries the applicator out of the path of the underlying type 27, the operation of which is delayed by reason of the stud 41 being spaced short distance above: the arm 40, as shown by Fig. 1. By the time the applicator 24 swings out of the path of they type 27, the stud 41 contacts and depresses the arm and effects the upward movement of the type 27 causing it to impinge against that portion of the paper extending over the platen 9 through the intermediacy ofthe key lever 43, the stud 41}, the bell-crank 34 and the type bar 30. When the depressed key 46 is released the parts are restored to normal position through the intermediacy of the associate springs 11 and 36. As the applicator 25 is carried forwardly and backwardly over the inksupply 26 the felt 24 is replenished. with ink and reinks the type 27, so that the printing on the paper will be distinct and of uniform color. Should the applicator lever 21 return to normal position before the type bar 30 after the key 46 has been released as stated, the rounded end 27f of the type holder 29 will contact the relatively broad surface 22 of the lever 21 and push the same out of the way against the action of the spring 11 and permit the type bar 30 to pass, the tension of the spring 36 being sufficient to overcome the spring 11 for that purpose. Members 48 underlying the key levers 43 are turned down to the dotted line position Fig. 1,. to avoid actuating the automatic mechanism hereinafter referred to.

Having described the manual operation, we will now proceed to describe the combined manual and automatic operation and more particularly the mechanism for carrying out the latter, it being understood that the automatic mechanism is employed more especially to gain speed in writing and re lieve the operator of fatigue arising from prolonged. manual operation alone. Member's 43' have slots 49 through which a flat bar 50' freely extends. Said bar 50 termireareao nates in journals 50 mounted in the lower portion 54 of the frame 4. Each member 48 when turned upwardly to the full line position, Fig. 1, is hold close to the underside of an associate key lever 43 by a retainer 51, reciprocably arranged in the frame portion 54 and normally held in raised position by a coil spring 63 tensioned by a set screw 64 threaded into the lower part of the frame portion 54 and prevented from coming loose by a locking device 64*.

57 designates a plurality of bolts, one of which is normally held upon the lower leg of the associate retainer 51 by a coil spring 55, which is weaker than the associate spring 63. The lower end of the spring 55 loosely embraces a stud 56 on the bolt 57 while the upper end of said spring 55 bears against a rib 53 eXtend-inginwardly from a face plate 54 secured to the front side of the of which is associated with each retainer 1 51 and bolt 57 and slides in a slot 66 in the lower part of the frame portion 54. Each plunger 62 is normally held in retracted position Fig. 1, against the action of coil spring 59, by a lug 62* which projects from said plunger 62' and bears against the end of the'lowcr leg of the associate retainer 51. The springs 59 are arranged in slots 58 in the frame portion 54 and tensioned by set screws 61 secured by a locking device-60.

Each plunger 62 is provided at one end with an eccentric 69 mounted upon an axis 70 and normally held from rotation by a lug 68 projecting over the slotted portion 67 of the frame portion 54. Each plunger 62 is provided with an upwardly extending shoulder 71, which constitutes a stop for a link 72 pivoted at its lower end to said plunger 62 and pivotally secured at its upper end to a connecting rod72 provided with a turn-buckle 42 connected at its upper end to the associate bell-crank 34. v i

74 designates a roller, preferably, provided with a rubber covering 73. Said roller.

74 is geared to an electric or other suitable motor (not shown) and is continuously driven when the operator is using the auto matic mechanism.

The operation of the automaticn'rechanism is as follows: The members 48 are adjusted upwardly to the full line position, Fig. 1, so that slight downward pressure upon any one of the keys 46 depresses the respective key lever 43, which in turn ac'tuat'es the applicator lever 21 as hereinbefere described in the manual operation. Said key lever 43 then forces the underlying member 48 and the retainer 51 downwardly against the action of the spring 63. The instant the lower leg of the retainer 51 moves downwardly out of the pathof the lug 62 the plunger 62 is forced longitudinally by the spring 59 and carries the eccentric 69' against the rotating roller 74. The forward movement of the eccentric 69 carries the stop 68 out of engageme-nt with the slotted portion 67 of the frame 54 and permits said eccentric 69 to be turned onerevolution by the roller 74. As the high radius of the eccentric 69 rolls into contact with the surface of the roller 74 it retracts the plunger 62 beyond its initial position, causing the shoulder 71 to carry the link 72 backwardly in an upright position, and through the intermediacy of the connecting rod 72*, actuate the bellcrank 34 before the same can be actuated by the stud 41. The bell-crank 34 in turn swings the type bar 30 upwardly to impress the character of the type 27 upon the paper as in the manual operation. The momentum imparted by the roller 74 to the eccentric 69 carries the same around until checked by its stop 68 again engaging the slotted part 67 of the frame. The instant the plunger 62 is retracted by the eccentric 69,-as stated, the bolt 57 is forced downwardly by the spring into the path of the lug 62 and prevents the plunger from being advanced another stroke by the spring 59. When downward pressure on the key 46 is removed the retainer 51 is immediately raised to normal position by the spring 63 and carries its lower leg into the path of the lug 62. As the retainer 51 moves upwardly as stated, it

raises the member 48 to normal position and. also raises the bolt 57 against the action of the spring 55, which as above-mentioned is weaker than the spring 63. The automatic mechanism has now completed one cycle and remains stationary until the key 46 is again depressed, when the foregoing operation is repeated.

e will now describe what we term the repeating mechanism whereby the same character may be quickly printed two or' more times when occurringin a number having successive duplicate characters such as 00, etc. 77 designates supplemental key levers, Fig. 5, arranged beside the main key levers 43 and provided with supplemental keys 46. Said key levers 77 are fulcrumed at 78 and provided with hooks pivoted at 76, so that they may be swung upwardly over the associate main key levers 43. lower end of each supplemental key lever 77 is arranged to actuate an associate latch 79 pivoted at 80 and adapted to enter a notch 81 in the front side of the bolt 57. When the supplemental key lever 7 7 is depressed it depresses the main key lever 43 through the intermediacy of the hook 74, causing the operation of the applicator lever 21. Depression of the supplemental key lever 77 as stated causes its lower end to push the lower end of the latch 79 into the notch 81 and The thereby hold thebolt 57 in raised position, so thatthe plunger 62may again advance and repeat the printing of the character without requiring the operator to again depress the key 46.

When automatic operation of the type bars 30 is not desired and manual operation alone is preferable,the bar 50 is rotated one quarter of a revolution to carry the members 48 downwardly to the dotted line position Fig. 1, so that the key levers 43 may be operated without actuating the automatic mechanism. The links 72 swing idly upon the pivots when the connecting bars 72 are actuated by the bell-cranks 34.

From the foregoing description it is ap parent that wehave provided a writing machine which is positive in operation and embodies the advantages above pointed out, and while we have shown and described the preferred construction, combination and arrangement of parts, we reservethe right to make such changes as properly fall within the spirit and scope of the invention as claimed;
