TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Jan. 28, 1919.

Application filed December 8, 1917. Serial No. 206,181.

To all whom it may concern:

Be it known that I, VVAnn S. IRELAND, a citizen ofthe United States of America, a resident of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in typewriting machines. Prior to this invention typewriting machines, especially shorthand machines, have been provided with means for feeding a continuous strip of paper which usually unwinds from. a roll and passes to a printing device, whereby the characters are printed line by line. Owing to the peculiar requirements of a shorthand machine, .it is a decided advantage to use a very long strip of paper so that the writing or printing. may be continued for a long period of time without frequent interruptions. However, considerable difiiculty has been experienced in handling the long strip of paper after it passes from the printing elements.

The .main object of my invention is to produce a very simple means for cutting the paper into relatively short sections. The preferred form of the invention includes a cutting device under the control of a cutting key. This cutting key is independent of the printing keys, and it may be actuated at irregular inter'va'ls to ,cut the paper into nonuniform sections, For example, at the end of a letter or other dictation relating to some particular subject. the cutting key may be operated to sever the paper. y' using the cutting key in this manner, the long strip of paper can be divided into irregular sections, each provided with printed matter relating to some particular subject. The relatively short sect-ions can be easily han died, and they maybe conveniently filed for future reference.

In the structure I have'shown, the paper advances, step by step in response to movements of the printing keys, and the paper is also fed by the cutting key. When the cutting key is actuated, the paper advances to locate the last line of printed matter at a point beyond the cutting elements, and one of said cutting elements then moves across the path of the paper. By feeding the paper immediately before the cutting operation, all of the printed matter will appear on the severed sheet of paper.

Figure I is a side elevation of a shorthand machine constructed in accordance with my invention, a portion of one of the side walls being broken away to show the means for actuating the cutting device, also showing the means for feeding the pa per immediately before the cutting operation.

Fig. II is a plan view, partly in section, of the rear portion of the machine.

Fig. III is a transverse sex-tion taken approximately on the line IIIIII, Fig. IV.

Fig. IV is a longitudinal section of the machine.

Fig. V is a detail view of the paper feeding roll.

Fig. VI is a section taken approximately on the line VI-VI, Fig. V, showing the clutch through which movement is transmitted from the printing keys to the paper feeding roll.

Fig. VII is a section on line VIIVII, Fig. V, showing the retaining clutch associated with the paper feeding roll to prevent retrograde movement.

To illustrate the invention. I have shown a shorthand machine provided with printing keys 1 secured to key levers 2, the latter being pivotally supported by a pivot rod 3 (Fig. IV). Each key lever 2 is provided at its rear end with an upwardly extending printing hammer 4L adapted to cooperate with a type bar 5 having type characters 6 on its bottom face. An inking ribbon 7 passes between the type 6 and the printing hammers 4. Each key lever is arranged directly below a restoring spring 8 (Fig. IV), and the restoring springs yieldingly hold the key levers in their non-printing positions. The. strip of paper 9 (Figs. I and IV) passes from a supply roll 1.0, under a rod 11, thence upwardly and over a paper feeding roll 12, downwardly through an inclined passageway 13, and then rearwardly to a cutting device near the rear of the machine. The paper travels between the printing hammers 4 and the inking ribbon 7 before it reaches the cutting device. When a printing key is depressed, its key lever 2 turns about the axis of the pivot rod 3 (Fig. IV) and the printing hammer 4 at the rear of the key lever moves upwardly to force a portion of the paper onto the inking ribbon 7, at the same time forcing the ribbon onto one of the type characters 6. The printing keys may be operated independently df each other to print selected characters, and several keys may be operated simultaneously to. print a line of characters, as is well understood in this art. The characters are usually printed line by line, a complete word or syllable being printed-during each key operation, the strip of paper is advanced one step in response to each key operation.

The paper feeding device comprises a universal bar 14 (Fig. IV) arranged over the key levers at a point in front of the rinting hammers 4 and fixedto a bell crank ever 15, the latter being pivotally supported by the pivot rod 3. The upwardly extending arm of this bell crank lever 15 is notched to receive a pin 16 (Figs. IV,V and VI) projecting from the oscillatory drive member 17 of a :paper feeding clutch. This drive member 17 is loosely mounted in a driven clutch member 18, the latter being secured to one end of the paper feeding roll 12. The drive member 17 oscillates freely in response to the movements of the universal bar so as to impart a step by step movement to the paper feeding roll. When the oscillatory drive member 17 turns in the direction indicated by the arrow in Fig. VI, the small spring pressed rollers 19 are freely clamped in the tapering or wedge-shaped spaces between said drive member and the driven clutch member 18. Movement is then transmitted from the universal bar, through the drive member 17 and rollers 19, to the driven clutch member 18. The paper feeding roll is secured to the driven clutch member 18 (Fig. V) so as to advance one step when the oscillatory drive member 17 turns in the direction indicated by the arrow in Fig. VI. During the reverse movement, when the drive member 17 moves oppositely to the direction indicated by the arrow in Fig. VI, the small rollers 19 tend to move away from the points of the tapering spaces, and they do not transmit movement to the .driven clutch member 18. In response to the oscillatory movements of the universal bar and the drive clutch member 17, the paper feeding roll 12 turns continually, step by step in the direction indicated by the arrow in Fig. VI.

the rotary clutch member 18'; These small rollers 19 allow the feedroll to turn freely in the direction indicated by the arrows in Figs. VI and VII, but if an effort is made to reverse the direction of movement, the

small rollers 19', by tending to move toward the points of the wedge-shaped spaces, will cooperate with the stationary clutch member 17 to prevent such retrograde movement.

To illustrate the preferred form of the invention, I have shown a cutting device including blades 26 and 27 (Figs. II, III and IV) located at points on opposite sides of the path of the paper, and adapted to sever the paper after it passes from the printing device. The blade 26 is closely fitted to an arcuate seat on an oscillatory blade holder 28. This arcuate blade 26 is secured to the blade holder 28, as shown most clearly in Fig. IV. When the blade holder 28 moves downwardly from the position shown in Fig. IV, the blades 26 and 27 cooperate with each other to sever the paper.

The blade 27 is referably secured to an arm 31 (Fig. IV) the latter being pivoted at 32. A spring 33, connected to the arm 31, tends to force the blade 27 into the path of the arcuate blade 26. When the blade 26 occupies the elevated position shown in Figs. III and IV, an extension 26', extending downwardly from the blade 26, ,is engaged I mounted in suitable bearings, and an operating arm 37 is rigidly secured to the journal 36. A restoring arm 38 (Figs. I and III) extending downwardly from the journal 36, is connected to a restoring spring 39 which normally retains said arm 38 in engagement with an abutment 40, thereby yieldingly retaining the oscillatory blade holder 28 in its elevated position.

' 41 designates a cutting key (Figs. I and II) in the form of a bell crank lever, pivotally supported at 42, and connected by means of. a link 43, to the operating arm 37. This operating arm is provided with a pin 44 which lies in a slot 45 at one end of the link 43. A' spring 46,secured to the link 43,

tends to retain said link and the cutting key in the positions shown in Fig. I. It will now be understood that the cutting key 41 may be actuated to drive the operating arm 37,

thereby turning the journal 36 so as to actuate theoscillatory blade holder 28. The operating arm 37 and blade holder 28 are both rigidly secured to the journal 36..

The paper feeding roll 12 is secured to a shaft 47 provided with a ratchet Wheel 48 which lies adjacent to the link 43 (Fig. I).

A pawl 49, pivoted to the link 43, is normally held in engagement with a pin 50 (Fig. I) by means of a spring 51. This spring is attached to the link 43 and also to the pawl 49. The point of the pawl lies near the ratchet wheel 48.

It will now be understood that the printing keys'can be actuated to print selected characters line by line, and to feed the paper step by step from the printing device to the cutting device. The printing keys are free to move independently of the cutting key 41, so as to print upon and feed the paper continuously, without actuating "the cutting device. The ratchet wheel 48 (Fig. I) turns, step by step, with the paper feeding roll 12, but this does not in any way affect the cutting device.

The cutting elements 26 and 27 are located near the path of the paper at a point beyond the printing device as shown in Fig. IV, and the last line of printed matter lies very close to the printing device. Several lines of printed matter are normally located between the printing device and the cutting elements. Therefore, the strip of paper should be advanced. or fed, immediately before the cutting device is actuated, otherwise the severed sheet of paper would not include all of the printed matter.

hen the cuttin key is depressed, the paper is automaticailyfed the required distance to locate all of the printed matter beyond the cutting elements, and the blade 26 then moves across the path of the paper. At the beginning of .the downward movement of the cutting key (Fig. I) the pawl 49 cooperates with the ratchet wheel 48 to turn the paper feeding roll 12, thereby advancing the paper. At this time the slot 45, in the rear end of link 43, allows the link and cutting key to move independently of the cutting elements. Thereafter, the point of the pawl 49 passes from the ratchet wheel 48, and a continued downward movement of the cutting key will cause the cutter-operating arm 37 (Fig. I) to move. to the position shown by dotted lines. The paper feeding device is thus actuated independently ofthe printing keys to feed the last few lines of printed matter through the space between the cutting elements, and thereafter, while the paper is at rest, the cutter is actuated to sever the printed matter from the blank portion of the strip. All of this is preferably accomplished by a single stroke of the cutting key.

The paper feeding device actuated by the printing keys is claimed in an application for patent filed by me on May 19, 1917, Serial Number 169,621. The paper straightening device comprising the rod 11 combined with a paper feeding device as herein shown, is claimed in an application for patent filed by me on May 19, 1917, Serial Number 169,620.
