To all whom t may concern.'

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

-My invention relates to improvements in typewriting machines, and the novel features of the invention are particularly adapted for use in shorthand machines. Prior to this invention, shorthand machines have been provided with means for feeding a continuous strip of paper, which unwinds from the roll and passes to printin devices, whereby a continuous series of s orthand characters are printed upon the paper. Owing to the peculiar requirements of a shorthand machine, it is a decided advantage to use a verylong strip of paper so that the shorthand writing may be continued for a considerable period of time without frequent interruptions, and heretofore' the paper supply has been firmly wound in a compact mass around a core or reel. Since the paper is primarily curled around the' axis of a roll, it tends to return to a curly or spiral condition after passing from the machine. If torn from the machine in comparatively short strips, the paper would be in the form of small curls containing the notes to be transcribed by the stenographer, and it will be apparent that such paper is quite diicult to handle. Owing to the length of the paper, and its tendency to recurl the paper handling devices of shorthand machines have not been entirely satisfactory.

Therefore, one of the ,objects of this invention is to produce a shorthand machine adapted to unwind and feed the paper from a roll, and also adapted to obviate the labor of handling curly strips of paper. With this object in view the machine includes a paper straightening device adapted to straighten the paper after it passes from the supplyroll. More specifically stated, an

object of the invention is to produce a simple paper straightening device associated with the otherelements of a shorthand machine in such a manner that the desired uncurling or straightening action isobtalned without being impairing the operation of the machine. Another object is to -produce a typewriting machine having a paper straightener which becomes effective upon the pperation of the key levers of the machine.

A further object of the invention is tobefore it reaches the shearing device and at a point where the crease will not in any way interfere with the action of the printing elements.

With the foregoing and other objects in view the invention comprises the novel construction, combination and arrangement of parts hereinafter more specically 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 within the scope of the claims hereunto appended. l

Figure I is a longitudinal section of a shorthand machine embodying the features of my invention.

Fig. II is a fragmentary plan View illustrating the paper straightening device.

Fig. III is an enlarged side elevation, partly in section, showingthe paper feeding device and the paper straightening device.

Fig. IV is a vertical section'taken approximately on line IV-IV, Fig. I, looking toward the front lof the-machine.

Fig. V is a detail view illustrating the printing device/and the means for vfeeding and straightening the paper.

Fig. VI is an enlarged detail view of the paper creasing rolls. l Y,

Fig. VII is an enlarged perspective view of Aone of the bearings 'for the lower creasing roll. i

To illustrate the preferred form of the invention, I have` .shown -a shorthand machine provided with .a housing 1, a'type holder 2 arrangedin said housing (Fig. I),

a type bar 3 in said type holder, and an inking ribbon 4 adjacent tothe line of type on the type bar 3. The paper passes' from a supply roll -A, over a roller =5, under and partially around a roller 5', in front of and over a roller 6, and then to al paper feeding device whereby it is unwound from the roll and fed through an opening 7 atl the rear of the machine, s ee Fig. I.'

The key actuated devices (Fig. I) pref-i' wardly from its arm 8, and an .arm 11 extendlng upwardly fromv the rear portion of said arm 10. vThe series of key levers is pivotally supported by a pivot member 12 located at-the junctions of the

lever arms

10 and 11. The upperend of each lever arm 11'is provided with a forwardly extending printmg hammer 13 which lies adjacent t0 the type 3, as shown mostv clearly in Figs. I and III.' Restoring ,springs 14 (Fig. I)

with an abutment 15.- i

When one of' the-finger keys 9 is depressed, the keylever associated-therewith turns about the axis of pivot member 1 2 and tend to retain the key levers in engagement a -printing yhammer 13 moves toward the type 3, thereby forcing the paper-and inking ribbon toward the'type and printing one of the type` characters onthe paper. The key levers may be operated independently of each other, or anyv desired number of key leversmay be operated: simultaneously.

The universal bar associated-with the key levers includes a transverse abutment holder 18 arranged in front ofthe series of lever arms 11, and provided' with a yieldable abutment 19 which engages all of said lever arms 11. The universal baralso includes.y

a pair -of arms 2O and 21 pivotally supported by the pivot member 1 2, arranged on opposite sides ofthe lever arms 11 as shown most clearly in Fig. IV, and secured near thelr upper ends to the transverse abutment holder .18. ,'22 designates a connecting member umting the

arms

20 and 21 of the universal bar, said connecting member being located at the rear of vlever arms 11. 23

ing lto .retain the universal`I bar in the poe sition shownffin the drawings. The transverse abutment 19, forming part ofthe Zuniversal bar structure, is so arranged that the universal bar will move in response to movements of any one of the key levers,

The paper feeding device preferably comprises a rotatable shaft 32, a pair of feed wheels 33 and 34 fixed to said shaft, a ratchet wheel 35 also fixed to a shaft, and a pawl carrier 36 loosely secured to said shaft. 37 designates a pawl pivoted to the

pawl carrier

36, and 38 designa-tes a spring connecting said pawl to the pawl carrier. The spring 38 tends to force the pawl into engagement with the ratchet wheels 35, as shown by dotted lines in Fig. V. The arm 21 of the universal bar is provided with an extension 39 (Figs. IV and V) which cooperates'with an arm 40 on the pawl carrier 36. A spring 41, secured to the universal bar, forces the arm 40 into engagement with the universal bar extension 39, said \arm. 40 being provided with a pad which bears against said extension, asseen in Fig. V. This arm l40, forming part of the pawl carrier 36, is so arranged between the spring 41 and universal bar extension 39,

that the pawl carrier will partake of the movements ofthe universal' bar. It will l now be understood that the pawl carrier 36,

as well l`as the universal bar,- is under the control of the key levers, and that the pawl carrier is adapted t0 oscillate 1n response to movements of said key levers.

When a key is depressed, or when several keys ,are depressed simultaneously, the universal bar moves forwardly. and the pawl carrier 36.turns about the axis of shaft 32 so as to advance the ratchet wheel 35 lo'ne step, thereby turning the feed wheels .and 34 to unwind the paper and advance 1t'^-one step. At the end of the paper lfeeding oper? `movement th paper feeding pawl 37 moves .1 .l

idly along the ratchet wheel 35. n

.To insure anl absolutely positive feeding action, the margins of the paper A are preferably perforated, `as shown in Fig. II to receive the teeth -which project from the periphery of the feed wheels 33 and 34. 45 designates" presser arms, pivotally supported by stationary arms 46 and provided with grooves 47 (Fig. IV) -for the receptionj of the teeth on the feed wheels. These arms 45 engage the paper at points on opposite sides of the teeth of the feed wheels,

so as to positively retain the pa er in engagement withsaid wheels.' deslgnates a restoring spring (Fig. I) tend- Each presser arm'45 is' preferably provided with two lnotches 50 and 51 (Flg. III) adapted to receive a springpressed detent 52. When the pressing devlce occupies its which lies in a notch 51. In applying a new roll of paper to the machine, the presser arms are shifted away from the feed wheels to an inoperative position (dotted lines in Fig. III) wherein they will permit the paper to be fed, by hand, over the feed wheels. At this time, each presser arm 45 is retained in its inoperative position by a detent 52 which then lies in al notch 51.

The means for straightening the paper preferably comprises a creasing roller 53, journaled in the presser arm 45, and provided with an annular rib 53 adapted to enter an annular groove 54 in a roller 54. The 'rollerl 54 preferably lies between the feed wheels 33 and 34, and it is rotatably supported by bearing members 55, each of said bearing members being provided with a substantially semi-circular seat 55 (Fig. VII) adaptedV to receive said roller 54. Since the paper is firmly coiled around the aXis of the supply roll, it tends to return to a curly condition after passing from the roll. However, when the paper passes between thev creasing rollers 53 and 54 it is uncurled or straightened by the creasing action which takes place at said rolls. The annular rib 53 forces' the middle portion of the paper into the annular groove 54, thus creasing the paper so as to form a reinforcing rib or ridge which stiifens the paper and prevents it from recurling. The perforations in the margins of the paper are preferably larger than the teeth of the paper feeding wheels', so that the paper will not be 4torn by the action of the creasing rolls 53 and 54.

After passing from the creasing rolls, the straightened paper advances vstep by step to a shearing device, whereby it is cut into small uniform sheets. The shearing m device I have shown (Fig. I) includes a stationary blade 57 and a movable blade 58. The movable blade may be operable by any suitable automatic mechanism.

' The creasing roll 53 is carried by the pivotally supported arms 55 and it is yieldingly held in its operative position by the spring pressed detent 52 (see Fig. III). When the arms 45 are shifted to the position shown by dotted lines in Fig. III, the creasing roll 53 is locked in an inoperative position so that the strip of paper may be readily inserted between the creasing rolls.

By locating the creasing rolls 53 and 54 at the path of the paper at a point between the printing device and shearing device, I form a longitudinal crease in the paper at a point where it will not impair the action of the printing elements and at a point where it will straighten the paper before the latter reaches the shearing device.

From the foregoing it will be understood that the creasing rolls I have shown to illustrate the preferred form 0f the invention, become effective upon the operation of the paper feeding device, the paper being positively pulled by the paper feeding device and in frictional engagement with the creasing rolls 53 and 54, so that said creasing -rolls will rotate in response to movements of the paper feeding device.
