Application filed September 7, 1906. Serial No. 333,686.

i T9 all 'ir/7mm 'it wally concern.'

Be itknown that l, HARRY C. Fnueijsox, a citizen oit the United States, andfresiding at Canton, in the county .of Stark and State of Ohio. have invented certain new and useful l mpi-ovements in Typedl'rriting Machines.' ot' which the followinp` is a specification.

My .invention relates to typewritingf machines and more particularly to means for actuating the printing' instrinnentalities concurrently with or by the travel. of the car-4 riage, the invention being especially adapted for whatmay bettermed liner i work such as the production ot' `following-lines" in bills, statements and indexes: for producing lilies of stars or for underscoring and the like, and the object ot' the invention'is to provide simple and elicieiit ni'eans of the character specified. l

To the above and other ends which will hereinafter appear. my invention consists of the features or" construction. arrangements of yparts and conihinationsl of devices to he set forth in the following specification and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various viewsVlVigure l is a rear-'perspective view showing' my improved attachment properly.connected to a typewriting machine, the platen` platen trame and ditferent parts associated therewith he- Fig.v 2 is a detail perspective type har andthe `diit'erent parts designed to actu ate the har.- Fig. 3 is a detail top view of the actuating rack bar and some of the parts associated therewith. Fig. 4 is a detail rear view showing a portion ot the rack bar and vthe adjustable release device or plate connectl ed thereto. IFig. 5 1s a detail rear View showingl a portion of the actuating rack bar with the setting' device connected therewith. Fig. Gis an enlarged detail view of the releasing and connecting block or Wedge.

ln various characters of work it is customary to .employ following-lines7 or leaderlines, lines ot stars showing an omission and underscoring. The use of such lines is well.

iinderstood' i Ordinarily lines of the character referred to above4 have been produced by repeatedly more particularly to accomplish liner work of the above and like characters rapidly and etliciently and to effect a .material saving of time and labor on the part ot' the operaitor in preparing such work and hy automatically and iiitcrniittently actuatinga type character during' the travel of the carriage.

There are various styles or kinds of typewriters. In vsome machines the paper is applied to a carriage which travels while the printingr instrumentalities remain relatively stationary. ln other machines the printing instrumentalities are mounted on a traveling carriage while the paper holding devices remain relatively stationar i. I have elected tp show my invention carried out in the first mentioned kind of writing machines, but I do not wish to lbe continedor limited to a inachine of this description, as myinvention may he carried outin any known style or kind of typewriting machines.

In the drawings, l represents in a conventional inanner,the frame of -a typewriting machine. The carriage Q-in the present in- ,stance carries a platen (not shown) andis mounted in the usual manner and is provided with-the usual .feed rack 3. rack which in the present instance in the torni ot' a straight toothed har 4f is secured to the carriage as shown in Fig'. l, said rack being provided with teeth 5 located upon the un dersidc ot the rack bar and heine' in 'the nature of 'ratchet teeth, the straight or ah- .rupt -face ot'each tooth heingon the lett-hand side as seen from the trout .of the machine: the inclined tace being' on the right. The

teeth 5 are preferably spaced a letter-space distance apart. vTo the Frame l of the inachine is attached a yoke-like bracket' scoured tothe top plate ot' the machine and provided with upwardly extending' ends or arms T and S which carry a pivot rod 9 secured at itsends in thel arnis T and S. A hollow shaft or sleeve l0 is mounted to turn on said pivot rod and is provided with crank arms ll and l2, the crank arm ll having; a tooth at its free end for' cooperation with the teeth 5 formed on the ratchet bar.

The second crank arm' 12 is connected to an actuating link lf extended down 'ardly and pivotally connected to one 'ariu of a bell ffrank or angular lever lft pivoted to a de-1 pending bracket l5 secured to the top plate of the machine. A-link 16 is pivotally connected to the other arm ofthe bell crank lever 14 and extends horizontally from the lever 'and has at its opposite end -an eye which looselyA surrounds an Iactuating link 17 for a type carrier or type bar. guide 16a is provided for the 4forward part of the link 16,'said guide extending down from the' top plate and having a -loop 'at the lower end through which the link 16 works. .The link 17 is connected at its upper end to a crank arm 18 formed-integral with or attached to a rock shaft 19 which constitutes the axle of a type bar 20 which, in the present instance, ,is shown as .the usual form of type bar employed in the Smith Premier typewriting machine This type bar is employed for liner work ,.the type thereon being in the naturebf a dash mark, star, lunders'coringmark o r the like. It will be understood that when the parts are in operative position as shown in Fig. 2 and the carriage 2, to'- gether with the different parts carried thereby, is moved toward the rightor to the left as y'seen in Fig. l, ashort vibrating movement will be imparted tothe crank arm 11 by the cammingl action of the inclined faces of the teeth 5, one vibration of the arm 11 being effected for each letter space movement of the carriage, so thatI if the carriage is moved a twenty-live letter space distance the arm 11 will receive a corresponding numberof vibrations. The movements of the 4arm 11 are imparted-to the arm 12, the link 13, bell crank lever 14 and link 16,

which latter is moved fore and aft of the machine and imparts a swinging movement to the upper endof the type bar actuating the movement of the carriage to the left orlink 17 which effects a swinging or printing, movement of the type bar 20. The move'- mentsv just above described are, as hereinbefore explained, automatically imparted by and during the travel of the' carriage to the right, at which' time the line work in the statement, bill 'or'.index' is produced, each movement of the carriage to the right pro,

ducing a line of dashes, dots, stars, 'under- 'scoring marks or the like.

-fffIt will be understood that as the carriage a 'proaches the limit of its mo,veme nt to the rlght, the arm' 11 must be disengaged from the rack or` tooth bar 4 so that the type bar 20. will not be brought into action during in the direction of its feed. In order that this resultmay be accomplished a shifting vdevice comprising a wedge-shaped block 21 is provided, said block being located between the arm 7 of the bracket 6 and one end of the rock sh'aft 10 as best illustrated .in Figs. 2 and 3. The straight faced portion 22 of the wedge 21 is held against t-he bracket arm 7 b a spring .23 locate bei tween the arm 8' of the bracket and oeend of the rock shaft or sleeve 10. and when said sleeve is located with its forwardend'abn'l j ting against the straight face portion 22a of the wedge or shifting device the arm 11 will be directly below the rack'bar 41. 'Whem however,Y the` .shifting device or wedge'- shaped block 21 is4 moved endwise or towards the left as seen inA Figs. 1. 3 and 6, the. beveled face of the wedge will move the rock-shaft 10 longitudinally on its. pivot. 9 towards theli'ear of the machine and Vthe arm 11 will be moved out, of vengagen'ient 'with the rack bar 4 into a position where the 4arm `cannot coperate with said rack bar.

Thisrenders the lrack bar and carriage to which it is connected free to move. together to the left or in thedirection of the feed of the carriage without rimparting any' movement to the. type bar 20.

,. For the purpose of automatically moving the rock shaft 10 longitudinally by the movement of the wedge 21 in the manner described the rack 4 is provided with a strike plate or abutment 24 which is adjustably attached to the rack bar 4 by a screw and slot connection', the abutment being held firmly in its adjusted position on the4 rack b y a screw or its equivalent. When the carriage has'moved to the right and has about reached the limit of such movement the depending engaging portion 'of tle abutment 24 will come into Contact with an end of the wedge 21 and will move it'longitudinally a sufficient distance to slide lthe'rock sha'ft or sleeve 1() on the rod 9 and against the tension of the spring 23,said rock shaft. being held in the p'osition to which itis moved until the wedge is 'moved in anopposite' direction from that imparted to it. by the' abutment 24. Near the right hand end of the rack 4 or upon some other suitable por-l tion of the carriage is' attached an adjustable plate 26 which plate is provided with a downwardly extending strike arm or abut-lv ment 2 7 which is for the purpose of moving the Wedgey end-wise when: the-carriage=-is The adjustable plate is so arranged that wheni substantially the eXtreme movement of the carriage tov the 'left has been brought about, the wedge 21 will be moved with the 'carri'ageto the left a suflicient'ldistance to allow the rock shaft 10 to be moved endwise lby* means Aof the'spring'23. This endwise movement of theiock shaft brings the arm 11 directly under the rack 4 and' in a position to. be actuated by the rack' when the 'carriage isY moved to the right. lt will ,be seen that b v riage an alternating movemen-twill be imparted to the. wedge block 21 by the abutments 24 'and 27, shifting it first to the left and then to the right. w

It will`be understood'jthat avery rapid .Y the back and forth movements of the car Y position.

bell ci:

totally-attached to a bracket 2!) and is substanially iai the forni shown and has an up* Wardly extending-'arm with which a. rea.r. 'Wardly projecting; pin 30 on the member 26 coperaties. when the carriage inoved to the right. The effect ofthe pin 50 contact* ing with the upright erin of the angular lever is to move the lower rearwardly projecting arm of said lever upwardly, theyre-l by elevating a link 31 connected at its upper end to the' angular lever and at its lower end te the rear arin of a le'ver 32 of the first order pivoted to a bracket secured to the 'base of the machine and having the link l? pivoted. to its forward arm. lThe elevation ot the link `l'inoves the lever 32 against the tension of the spring 37 connected therewith and with. the base of the machine.. This moves the type bar' actuating linki7 downwardly 'and elevates the type b'ar 20 but not a sutticient distance to come into Contact with the ribbon or the platen7 so that' when a printing movementfis given to the link 17 the type bar will have-but a short distance to travel to reach the printing position. The top of the upright arm of t-he lever-'28 is beveled iiliere it cooperates with the pin 30. and in the operation of actuating` 4the lever 28by the pin 30. said pin passes beyond the upright lever arm and to the right thereofl shown in dotted lines in Fig. l. A

l" or the lpurpose of holdingthe lever 28 in the position to which it is moved by the pin B0. a locking device or pivoted arm 3ft is provit'led, said locking device being forced into the position .illustrated in Fig. 2 by means ot the spring the free 'end oit' the locking device engaging a notch 36 ,in the upright lever arm to hold said lever in opi` erated posit-ion. This maintains the link 31 elevated and the forward end of the lever 32 depressed, which is eective to maintain the type bai' inan elevated position a short dis `tance lfrom the face of the platen, las hereinbefore explained. this arrangement the type ba'r 2O is vonly required to move a short,v

`distance at each print-ing operation;` butv when the lever 2S is freed from its locking,l

device the spring 37 pulls the rea-r end ot the levier flown, thereby restoring the link 31, lever 2.8,flink 't7 and t'vpe bar to their normil posit-ions and enablingithe type bar 20 to move out ot the paths ofthe other type bars.y

` l and the parts associated. l .therewith are employed. This lever is p1 v- A cani S9 is carried by the rack 1L and is adapted. to coipci'ate with a finger or pro jectiou 3S on the lot-killer device Bft, when the carriage i moved to the rig-ht to'diserg-age .said locking' device from the lever ln order to alliowthe pin 30 to pass the upright arm of tihe angular levcr 2S from right to lett, when the pin is to the right of said lever, Ias :indicated in dotted lilies in Fig. ll, the pin 30 is beveled on its end as best .shown in Fig. 3i so that it will push 28 rearwardl i as the pin moves with the carriage during the travel of the latter to the left.. 1v/heu said pin has passed to the lett of and fcleared the upright lever arm, said arm is'tree to spring;v back to its normal position to be again engaged by the pin when the carriage is moved to the right. l1 will be understood that theupright arin ot the lever 2S should be so constructed and `connected ivith its portion above the pivot of the/lever that it will have a spi-intlr action or a certain degree of resiliency which enables it to be forced rearwardly by the engagement of the beveled end of thepin 30.

Ordinary shouldered setScreWs 40 may be employed tor holdingl tl'ieadjustable plate 26 in position, said scre'w engaging; in tapped openings in the rack 4 and passing through. a longitudinal Slot in the plate. B v adjusting' the contacts 24 and 27 and the pin 30,. the points, with reference to the travel ,of the carriage. whenthe wedge 2l. lever 28, lock 34, etc, are actuated may be nicely regulated., and bv-so adjusting the plate 26 that the pin 30 is inoperative on the lever 2S, or by removing the plate from the machine. the liner devices are rendered inoperative.

ln order that the type bar designed to be actuated by the rack 4, may receive a preliminary movement and be partially ellevatod before the arm l1 is actuated by the `rackfit is preferred that. the pin 30 moves the lever 2S before the teetlron said rack reach the arm l1. and become effective to actuate the type bar.

ln Fifz.- 2 ot' the drawing the arm l1 is with tlie'rack4 and the pin 30 has already actuated the lever 28'.' Two positions of the pin 30. one when it. has reached the lever 28 trated in full and dotted lines in Fig. L In t'ull lines in Fig. l the teeth of the racket have not vet engaged the arm 11. though the lever 2S is shown engaged b v-the pin 30. As the pin moves to the right, thus actuating the lever 2S, the teeth ot the raclnt are brought into engagement with the arm l1. dThe operation is as follows chine. the operator moves thecarriage to the orcaiu the upper resilient arm of the lever' shown after it has been set forcope ation and the other after it has 'passed it, ,are illus.

lli-5 The paper having been inserted in the in a-- right to begin a line of Writing. The .act ot moving the carriage to the right brings theabutment 24into contact With4 the Wedge or shifting device2l, thus camming the arm 5 1l ,towards the rear olf' the machine Where lit out o-coperat-ive relation with the rack '4:' and the carriage is at this time free to be moved or fed tothe left. This 'same movement of the carriage to the right brings the I cam or abutment 39 into contact with the projeotion- 38 on the locking device 34, thereby moving said device varound its pivot toward tlie'-front of the machine. The e'ii'ect 'of this is to release the locked lever 28 and 4 ]'"the, s'pring1 37 is operative to effect 'a restoraton Aof .the parts 32, 17, 31, 28 and theI type bar to their normal positions and the travel or feed of the carriage tol the left is 4ineffective to actuate lthe type bar 20.' The 2'0 operator proceeds to Write the line and when the end of the line is approached, the abut" nient v27 is bronghtinto contact with the Shifting device 2l, thus moving it to the lett Withthe carriage to bring the face 2211 into 2 5 cooperation with the end of the rock shaft 10,'. allowing, the arm l1 to'be brought into cooperation with the racket.v llhe operator then moves the carriage back to the right "and as it starts to move, the pin 30 coper- '30 ates 'with the upright arm the lever 28,

`-ishifting said lever on its pivot to the oper- -ated position shown in Fig. l and it is automatically .locked in such position by ,the locking device 34. At this time the parts are so disposedthat a movement of the car# riage to the right Will effect an intermittent actuation ot the type bar, thus causing a line of Vdash marks, stars or the like to be imprinted one 'for ach'V letter space move- 40 nient of the carriage.

From the foregoing description it will be s een that throwing the type bar into and out of operation is automatically edected by the travel of the carriage but it should be under- 45 stood that the lever 28 mayl be moved by hand at any time to the operative position shown in Fig. 2 and may be locked in this position it desired by the locking device 3-.1 or that the lever 28 may be released by hand at any time from its locked position.

vFrom the foregoing description it will be seen that'thc novel devices of in v invention v are in the nature'of attachments and may be applied to existing forms of type rltmg niachilies Without changing the structural t'eatures ot said machine. ltmvill also be understood that the carriage receives a continuous movementin its return to the right; that it is this continuous vmovement which 6'\ aotuates the type carrier 2G to eii'ect a suc- .invention cntemplating broadly the provision of means for automatically actuating the type carrier by or concurrently With the movement ot' thek carriage.
