To all whom it may concern:

Be it known that we, WARD S. IRELAND and WV LTR E. Lirrnn'r, citizens of the United Statesof America, residents, respectively, of the city of St. Louis, State of Missouri, and of Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Typewriting Machines, of whichthefollow ing is a full, clear, and-exact description, referencebeing had to the accompanying drawings, forming a part of this specification.

Our invention relates to improvements in typewritin machines, and more particu larly to in 'ing devices adapted for use in shorthand machines. One of the objects of the invention is to produce a very simple and inexpensive inking device. 7 Another object is to produce an inking device that can be-easily and quickly applied to, or removed from, a typewriting machine. A further object of the invention" is to produce a shorthand machine having auxiliary type characters for printing consecutive numbers, identification charactersor other matter, and a simple auxiliary inking' device associated with such type characters.

7 With the foregoing and other objects in view the invention comprisesthe novel constructiom combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown'ithe preferred embodi ment 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. f 7

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

Fig. II is a planpview of the rear portion of the machine, a portion of the housing being broken'away to show the means for shifting the inking web.

Fig. III is an enlarged-longitudinal section taken through the inking web and web holder.

Fig. IV is a perspective view of the inking web and web holder. 7

Fig. V 's aside elevation, partly in sec tion, illustrating the paperfee'ding device.

Fig. VI is a vertical section taken approximately on the line VIVI, Fig. II.

. Fig. VII is a horizontal section showing thekey levers, the universal bar operable by said key levers, and the ratchet and pawl.

device driven by the universal bar.

To illustrate the preferred form of the invention, we have Shown a shorthand machine provided with a housing 1, a type holder 2 in said housing (Figs. I and V) a type bar 3 secured in said type holder, and a main inking ribbon/1 adjacent to the line of typeoon 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 rod or roller 6, and then to apaper feeding device whereby it is unwound from the roll and fed through an opening 7 at the rear of the machine. ,The key actuated devices preferably include a series of angular levers each having an'upwardly extending arm 8 at its front end (Fig. I)' and a character key 9 at the upper end of said arm. Any suitable shorthand code may .be used, and the character keys 9 are preferably, but not essentially, provided with characters corresponding to the line of type characters on the type bar 3. Each of the key levers includes an arm 10 extending rearwardly from its arm 8, and an arm 11 extending upwardly from the rear'portion of said arm 10. The series of key levers is pivotally supported by a pivot member 12'located atxthe junctions of the lever arms 10 and-11. The upper end of each lever arm 11 is provided with a forwardly extending printing hammer 13 which lies adjacent to the type 3, as shown in 'Fig. I. Restoring springs 14. (Fig. I)

tend to retain the key levers in engagement with an abutment 15. 7

'-When one of the finger keys 9 is depressed, the key lever associated therewith turns about the axis "of pivot member 12 and a printing hammer 13 moves toward the type .3, thereby forcing the paper and inking ribbon towardthe'type and printing one of the type characters on the paper. The key levers may be operated independently of each other, or' any desired number of key levers may be operated simultaneously.

The universal bar associated with the key levers includes a transverse abutment holder 18 (Figs. I, V and VII) arranged in front of the lever arms 11 and provided with a yieldable abutment 19 which engages all of said lever arms 11. Thenniversal bar. also. includes a pair ofarms 20 the lever arms 11, andsecured near their upper ends to the transverse; abutment holder 18. 22 designates a connecting member uniting the

arms

20 and 21 of the universal bar, said connecting member be ing located at the rear of the lever arms 11. 23 designates a restoring spring (Fig. I) tending to retain the universal bar in the position shown in the drawings. The transverse abutment 19, form.- ing part of the universal bar structure, is so arranged that theuniversal bar will move in response to movements of any one of the key levers.

lhe paper feeding device comprises arotatable shaft 25, a pair of

toothed wheels

26 and 27 fixed to said shaft, a ratchet wheel 28 also fixed to the shaft (Fig. V) and a pawl carrier 29 loosely secured tosaid shaft. 30 designates a pawl pivoted .to the pawl carrier 29, and 32 designates a spring connecting said pawl to the pawl carrier. The spring 32 tends to force the pawl into engagement with the ratchet wheel 28, as shown by dotted lines in Fig. V. The arm 21 of the universal bar is provided with an extension 33 (Fig. V) which cooperates with an arm 35 on the pawl carrier 29. A spring 36, secured to the universal bar, tends to force the arm 35 into engagement with the universal bar extension 33, said arm 35 being so arranged betwcenspring 36.

anduniversal bar extension 33 that thepawl carrier will partake of the movements of the universal bar. It will now be understood that the pawl carrier 29 as well as the universal bar, is under the control of the key levers and that the pawl carrier is adapted to oscillate in response tomovements of key levers.

When a key is depressed, or when several keys are depressed simultaneously, the universal bar moves forwardly about the axis of pivotmember 12, and the pawl carrier.

29 turns about the axis of shaft 25 to advance the ratchet wheel 28 one step, thereby turning the

toothed wheels

26 and 27 to un-v wind the paper and advance it one step. At the end of the paper feeding operation, the.

printing hammer or-ham-mersl3 force the paper and. inking ribbon ,toward the type to print the selected character orcharacters. Thereafter, the universal bar and key lever or levers, return to the, positions shown in the drawings, and during this movement the paper feeding pawl30 moves idly along the ratchet wheel 28.

Themargins of the stripvofp'aper are preferably perforated,-;as shown in Fig.;;II,.

to receive the teeth which projectfrom the periphery of the

feed wheels

26 and 27. 38

designates a pressing device pivotally securedtostationary arms 39 and adapted, to engagethe paperat pointsnear the teeth of

the'feed wheels

26 and,,27 to prevent. the paper from becoming disengaged from said feed wheels during the paper feeding operations.

To. illustrate the invention, we have shown an auxiliary printing device consisting of countingwheels40-(Fig, I) provided with peripheral type characters for printingconsecutive 7 numbers on the. paper, and an identification wheel '41 forprinting identification characters on a the" paper. The, identification wheel {41 maybe -adjnstedby hand, and the counting wheels maybe operated automatically by any suitable mechanism. In thisconneotion it is to beunderstood, that the invention is not limited to counting device, nor toan identification de-- 35 vice, theseelements-beingshown merely forthe purpose of illustrating type members adapted for use in connection'with my inking device.

A small inking web 42, arranged between, the strip of paper and the type members-40 and 41, is seoured at its side margins to a. web holder B. 43 designates a platen (Fig. I) arranged below. the paper, and also be low the inking web 42. This platen 43 may be operated 'by any suitable mechanism to force the paperand inking web 42 toward. the type members 40 and 41. The web' holder B, shown most clearly in Fig. IV, is preferably a sheet metal member in the form. of a lever, having a pair offoppositely dis,- posed arms 44 which." are) folded ;to form. grooves for the reception of ,the side- .margins of web 42, the. foldedportions of said. arms being firmly forced Qintoengagement withweb 42 so as to secure the latter to the,

webholder ,B. The arms 44 form the side, walls, of, an openingada'pted to receive the; type members 40' and .4l,'fand the inking. web '42 extends; across this opening as shown; in Fig. IV. The. web; ho1de1. 13;iS, slottedvat 45 to receive a guidescrew 46 whereby said. web holder is detachably secured...to th'e... housing 1. A drive lever 47.;ia provided with a boss.which{extends througha,slot,4& 5 in the top wall of housing 1,sai, d drive lever. it being secured to the web holderB-zbymeans of a pivotscrew 49. (Figs. II and III.)

, It willbenoted that. th web holder Bis a very inexpensive device, andthat it. may=12o be easily and quickly applied to,or removed from the machine. The screws 46 and 491 preferably constitute the sole means for so. curing the web holder to the machine.

The drive lever 47 is pivotallysupported 12.5 at 50, (Fig-II) and it hasan.;ar;1i1.47 which engages a cam .51, the latter being fixed toa: vertical-shaft 52.- .53. designates a spring ,for forcing the drivelever into engagement .with cam 51. The means for operating the shaft 52 comprises a ratchet wheel 53 fixed to said shaft, and an oscillatory pawl carrying arm 54: loosely fitted to said shaft. The pawl carrying arm 54 is provided with an opening at a point immediately above the teeth of ratchet wheel 53 (Fig. VI) and a gravity pawl 55 loosely arranged'in said opening, engages said ratchet wheel. This ratchet and pawl device is adapted to operate silently, without producing the usual loud clicking sound, the pawl 55 being a small light member adapted to travel over the ratchet teeth without striking noisy blows on the ratchet wheel. .55 designates a retaining pawl (Fig. VI) fitted to the toothed lower edge of ratchet wheel 53. A yieldable link 56, in the form of a helical spring, connects the oscillatory pawl carrier 54: to the arm 21 of the universal bar, see Figs. VI and VII. The axis of the pawl carrier is at a right angle to the axis of the universa-l bar, and the link 61 is quite free to yield in transmitting movement from the universal bar to the pawl carrier, this being desired on account of the peculiar relative positions of said universal bar and pawl carrier. Another advantage of link 61 lies in the fact that it is free to yield longitudinally to compensate for any undue or abnormal resistance ofiered to the movement of the means for driving the web holder B.

During each operation of the universal bar, the ratchet wheel 53 advances one step, and the cam 51 turns with said ratchet wheel. The drive lever 17 oscillates in response to the rotary movements of cam 51, and the web holder B moves back and forth in a substantially straight line. It is true that the web holder oscillates slightly, but inasmuch as its movement is approximately in a straight line, we will term this web holder a reciprocating element it being understood that the term reciprocating is used in its broadest sense, meaning a movement forward and backward.
