Application filed December 8, 1917. Serial No, 206,180.

To all whom it may concern:

Be itknown that I, WARD S. IRELAND, a citizen of the-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 printing devices, 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 may period of time without frequent interruptions. However, considerable difliculty has been experienced in handling such paper after it passes from the machine.

One of the objects of my invention is to produce a shorthand machine having a very desirable key-actuated cutting device whereby the lon strip of paper is divided into relatively s ort sections, the present invention being an improvement on the structure shown and claimed in an application for patent on improvements in. typewriting machines, filed by me Nov. 18, 1916, Serial No. 132,071.

A further object is to produce a shorthand machine havlng an automatic cutting device whereby the paper is divided into uniform sheets after it passes from the printing device; in for rendering the automatic cutting device inefiective to allow the machine to be operated continuously -without actuating the cutting device. This enables the machine to be used indefinitely without cutting the paper. The machine herein shown is also provided with a cutting key, under the control of the operator, whereby the. cutting device may be actuated to cut the paper at note that the cutting key may be continued for a considerable.

combination with means any time. The cutting key may be actuated without in any way disarranglng the automatic mechanism. It will be important to be operated by hand when the automatic operating means is ineffective. The paper may then be cut and filed at the will of the operator, this being an advantage under some conditions. For example, in writing letters the paper may be cut and filed by actuating the filing key when the dictation of a letter is completed. *In this event, each letter will appear on an individual sheet, instead of being continued from one sheet to another.

If desired, consecutive numbers may printed at regular intervals on the long strip of paper, and these numbers will constitute page numbers for the severed sheets. The automatic operating means is so timed that a page number will appear on each sheet, and since the cutting key is independent of the automatic operating means, the

aper can be cut at any time without changing the relation between the numbered strip of paper and the automatic operating means. With the foregoing and other objects in view the invention comprises the novel construction, combination and parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention; however, it is to be understood that the invention comprehends changes, variations and modifications which come wi cope of the claims hereunto appended.

arrangement of 1 Figure I 1s a plan view, partly in section, of

on a small scale,

proximately on the line V-V, Fig. IV, showing the cutting device at the rear of the machine. Fig.liVI is a detail view of the paper feedro ig. VII is a section taken approximately on the line VIIVII, Fig. VI, showing the driving clutch whereby a step by step movement is imparted to the paper feeding roll. Fig. VIII is a section taken approxi-' mately on the .line VIIIVIII, Fig. VI, 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 4 adapted to cooperate with a type bar 5 having type characters 6- on its bottom face. An inking ribbon 7 passes between the type bar 5 and the printing hammers 4. Each key lever 2 is arranged directly below a restoring spring 8 (Fig. IV), and the restoring springs yieldingly hold the key levers in their non-printin positions. The strip of paper 9 (Fig. H passes downwardly from a supply roll 10, under a small paper straightening rod 11, thence upwardly and over a paper feeding roll 12, downwardly through an inclined passage-way 13, and then rearwardly to a cutting device near the rear end of the ma-. chine. The paper travels between the printing hammers 4 and 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 r d 3 (Fig. IV), and the printing hammer 4, at the rear of the key lever,'moves upwardly to forcea portion of the paper ontothe inking ribbon 7, at the same time forcing the ribbon onto one of the type characters 6. The printing keys may be operated independently of each other toprintselected characters, and several keys may be operated simultaneously to printa line of characters, as is well understood in this art. The charactors are usually printed line by line, a complete word or syllable being rinted during each key operation. The strip of paper is, therefore, advanced one step during 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 prints ing hammers 4 and fixed to a bell crank lever 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, VI and VII) projecting from the oscillatory drive memmeager in the tapering or wedge-shaped spacesibe= tween 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 12 is secured to the driven clutch member 18 (Figs. VI and VII), so as to advance one step when the oscillatory drive member 17 turns in the direction indicated by the arrow in Fig. VII. During the reverse movement, when the drive member 17 moves oppositely to the direction indicated by the arrow in Fig. VII, the small rollers 19 tend to move into the wide ends 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 drive clutch member 17, the paper feeding roll 12 turns step by step in the direction indicated by the arrow in Fig. VII.

To positively prevent retrograde movement, a stationary clutch member 17 (Figs. VI and VIII) is arranged within a rotary clutch member 18, secured to one end of the paper feeding roll 12. A pin 20 extendingfrom the stationary clutch member 17, is secured to a stationary side frame 21. Spring pressed rollers. 19' are arranged in the Wedge-shaped spaces between the stationary clutch member 17 and'the rotary we I clutch member 18. These small rollers 19" allow the feed roll to turnin the directionindicated by the arrows inFigs. VII and VIII, but if an-elfortis made to reverse the .direction of movement, the small rollers 19', vby 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 an automatic cutting device including bladw 26 and 27 located at points on opposite sides of the path of the paper and adapted to sever the paper after it passes from the printing, uncurling and feeding device. The blade 26 is closely fitted to an arcuate seat on an oscillatory blade holder 28. The arcuate blade 26 is secured to the blade holder 28, as shown most clearly in Fig. IV. A filing pin 29 IV), l0 cated below the oscillatory blade holder 28,

is arranged to receive the small sections of the long lever 43 and gradually increasing as paper severed by-the blades 26. and 27.

The timing cam 46 moves step abutment 42. 126 by step in v response to operations of the The means for actuating the timing cam printing keys, as will be hereinafter de- 46 includes a large gear wheel 53 (Figs. I scribed, thereby transmitting power through and II) fixed to the timing cam, and a pinion 54 meshing with said large gear wheel. The pinion 54 ls'secured to a shaft 55 pro ecting from one end of the paper feeding roll '12. This shaft 55 is shown in Figs. 1,11 and IV. It will now be understood that motion is transmitted from the key levers, through the universal bar, paper feeding device, pinion 54, and thence through the gear wheel 53 to the timing cam 46. The timing cam, therefore, advances one step in response to each key operation, and since said cam is operated through the medium of the paper feeding device, it will be apparent that the filed sheets will be uniform in length.

When it is desirable to operate the machine continuously without cutting the paper, the

operator can render the automatic operating means inefi'ective by locking the long transmission lever 43 (Fig. II) in an inoperative position. This is accomplished by forcing a hook-shaped latch 59 (Fig. II) into inoperative engagement with a pin 60 on the lever 43. A finger 61, extending .downwardly from the lever 43, may be engaged and manipulated to locate the pin 60 at a point near the hook at the upper end of latch 59, and the latter may then be manipulated to cooperate with the pin 60in holding the lever 43 in an inoperative position. The

timing cam 46 may then be rotated continuously without in any way afi'ecting the cutting device. A spring 62 normally holds the latch 59 in the position shown in Fig. II, and when this latch is hooked onto the pin 60 it may be easily released by moving the finger 61 downwardly, thus movingthe pin 60 downwardly and permitting the spring 62 to restore the latch 59 to the position shown in Fig. II.

A cutting key 63 (Figs. I and H) may .be operated at any time to cut and file the paper, without in any way 'disarranging the automatic mechanism. The cutting ke I have shown is in the form of a bell crank lever'pivoted at 64 and connected by means of a link 65 to a crank 66, the latter being loosely mounted on the journal 36. The movable blade holder 28 is fixed to this journal 36. When the cutting key 63 is depressed, motion is transmitted through the link 65 and crank 66 to the operating arm 37, thereby actuating the movable blade holder, as will be hereinafter more fully described, to cut the paper and to force the severed sheet onto the filing pin 29.

\Vhen the latch 59 (Fig. II) is engaged with pin 60 to hold the lever 43 in an inoperative position, the trippable operating means? is actuatedby the cutting key 63, and the shown in Fig. II.

If the cutting key is actuated when the projection 41, on the trippable operating member 40, is in the path of the abutment- 42, the latter in moving downwardly will strike the projection 41 and force it outof the way. During the return stroke of the oscillatory arms 37 and 66, a cam 67 carried by the loose crank arm 66 will move up wardly in advance of the abutment 42 so as to prevent the latter from being stop ed by the projection 41. When the cutting key is actuated, the lower portion of cam 67 engages the abutment 42 to transmit movement to the operating arm 37. It is to be understood that the cam 67 on the loose crank arm 66 performs no function when the cutting device is actuated by the automatic mechanism, and if the cutting key 63 is actuated when the automatic mechanism is in the position shown in Fig. II, the cam 67 will perform no useful function. However, if the cutting key is actuated when the projection 41 lies below and in the path of abutment 42, the abutment 41 must be shifted and held out of the way to permit the abutment 42 to return to its normal osition, and this shifting operation isperormed by the cam 67.

The strip of paper 9 which unwinds from the roll may be rovided with consecutive numbers at regu ar intervals, as shown in Fig. 111. The dotted lines in this view do ,not appear on the paper; they merely indicate the points at which the paper is to be severed by the automatic cutting device. The consecutive numbers on the paper serve as page numbers for the small sheets, and if the sheets are accidentally disarranged, the page numbers will clearly indicate the order in which they are to be replaced. When the paper is properly arranged in the machine, the cutting elements of the automatic cutting device will sever the paper at the points indicated bydotted lines (Fig. III) as previously suggested, and a page number will appear on each sheet. It is sometimes desirable to cut the paper by hand, while the automatic device is in its operative condition, and this hand operation may be performed by means of the cutting key63 without moving the timing cam 46. When the timing device is set to cut the paper at the predetermined points, the cutting key may be actuated at irregular intervals, and these cutting operations will not prevent the auto matic device from continuing to cut the paper at the predetermined points. The cutting key can be actuated at any time without changing the relation between the numbered strip of paper and the timing device.
