To all whom itmay concern: Be it' known hat I, Monms W. POOL citizen of the United States, d resident of the borough, of Brooklyn, cit of New York, in the county of Kings'an State 'of New York, have invented certain new and useful Improvements in 'lype Writin Machines, of whichsthe following is a speciiication.

Myinvention relates more articularly to theei'ibbon mechanism of t ose machines wherein the writin is visible to the o erator as it is written.' I n such machines t e ribbon'is usually controlled by a ribbon vibrator, which term, as herein .emplo ed, cullipiehendsjany device for moving t e ribbon automatically to cover the printing oint and for. afl'ording a movementof the 1'] men to uncover the printing point. In my pending application Serial No. 247,474, filed February 27th, 1905, I have shown means to so move the vibrator as'to cause the ty impressions to follow a plurality of pre etermined' paths longitudinal of the ribbon and parallel with each other.

with a feed rack 21 which normally meshes with a pinion22, the latter being operatively connected with an escapement wheel 23, the teeth whereof are adapted to cooperate. in a known manner with escapement dogs 24 mounted in a pivoted dog rocker 25; a The dog rocker 25 is provided with a horizontally dis osed arm 26, the forward end of which is connected-by a link 27 with an arm 28 projecting rearwardly from the central part of a pivot rod 29 having hearings in fixed pivots r a stra with the carriage 16 and tends conwith said sinion but de'penden twill top plate spring drum 33 three and 49, the first name ter draws the carriage stan y todraw said carriage leftward across the top plate. Whenever the universal bar is adequately depressed the feed-dogs 24, coeperating with t e other escapement members in a known manner, ermit the carriage to move one letter space eftward.

Ribbon spools 36 are pivotally above the top each side thereof and forwardly of the platen. A- ribbon. 37 is wound upon said spools and passes from one toathe other in front 3 the platen. Each ribbon spool is fixed to the upper end of avertical shaft 38 which rotates in a fixed bearing 39, said shaft being'promounted vided at its'lower end-with a small beveledgear 40. Meshing with thebeveled gear 40 is a beveled pinion 41 secured to the forward and of a ho ontally disposed shaft 42 vadapted to rotate in fixed bearings 43 and having fixedly secured to its-rear end a beveled pinion '44. Adapted to cooperate with thepinion 44 is a driving pinion 45 fixedl secured. on a driving or ower shaft 46-whic from side to s'i e-of the machine beneath the and is slidably mounted in fixed bearings 47. The driving shaft 46 is connected with and is caused to rotate by the h beveled pinions 48 pinion being cause torotate with the spring ion 49being so connected with the driving shaft 46'that the latter is caused to rotate has-endwise motion iny thereof. v L be understood that each ribbon spool is connected as above described with a beveled pinion 44', there being one of the latterat each side of the machine as seen in Fig.

4.- The beveled driving pinions 45 are so ardrum 33 having a pivot plate of the machine, one at extends I drum when the lat-' leftwardand the pinranged upon the driving shaft-46 that only one of said driving pinions is engaged at a time with its associate pinion 44. To accomplish the alternate engagement of the driving pinions 45 with their respective associate pinions 44 and thereby to cause the ribbon to wind from one s 001 to the otherand vice'versa, the power sha t 46 is given a longi tudinal movement to and fro. The preferred means of causin this to andl'ro longitudinal movement of the driving shaft is that 7 shown in the U: S. Patent to Jacob and Carl Gabrielson No. 703,339, dated June 24, 1901 and which will be hereinafter described. With the parts arranged as shown in Fig. 4 the present a plication the ribbon may be caused to win on the lefthand ribbon spool,

and wind off the right hand spool by means patent. When gll the ribbon has been wound oil the right. hand ribbon spool the shaft 46 ma by the means ex lained in said patent, he s ted lon 'tudinal y in the direction of the arrow in ig. 4' so as to cause the right hand driv' pinion 45 to en age with its pinion'44 and t e left hand driving pinion .45 todisengage from its associate pinion; The direction of the longitudinal feed of the ribbon is thereby reversed and the latteris caused to wind on the right hand spool and off the left hand spool. pivoted vibratory spring pressed detent 50, engaging with a circumferential depression 51 in the driving such as those ex lained in the above cited shaft 46, serves to retain the latter 'in either of. its working positions and has the additional function of assisting toshift said shaft frorri one working position to the other. I do not desire to be imited to the means for reversing the ribbon winding or longitudinal feed mechanism explained in said patent. .Any other automatic reversing means may .be

used with my invention or the ribbonmay be manually reversed as by pulling out or pushing in the handles 52 secured to the ends of the driving or power shaft 46 and ordinarily em loyed for ra idly windingthe ribbon.

(lentrall of tlie machine the ribbon is threaded t. rough a ribbon vibrator or vibratory carrier 53 which is uided. and supported in grooves in the uprig it arms ,54 o a supporting bracket 55 secured to the frame of r the machine by screws 56. The lower end of 'the vibrator 53 is bifurcated and is provided bar frame, and said actuating linkis provided a d ,with across pin 57 with which engages the slotted forward arm of an operatin lever 58 ing "from: iThe' 'rear at its upper end with a projecting-pin or stud" 65 which engages with the slot 61 in the opcrating lever.

The spline 78 is s ect. It will be-noted from an 'i action at: rovided "with a second notch or depreso fFig. 9 that with the arts positione aslast sion 79 some distance to the left of the notch descr1bed,. the ath w ollows a course al'o member 69 isada ted to the middle an lon itudinally of the 11 per e moved leftwarfiengthwise of the riving or black stripe 3 ith the pin 76 o the shaft 46 so. as tocause the lockingpin 7.6 to switching member 69 engaged with the notch 100 "disengage from the notch 77 and to e age 76 of the driving shaft, as now being consid- L-iwith the notch 79, The meanssho wn to onered, the types will ordinarily contact with gitudinally position the switching member 69 the ribbon along the path at until the right I comprises a forked member 80, the lower bihand ribbon spool is empty.

The rotary arm 85 serves to transmit an increased movement due to the throw or switching movement of the switching member, so that though the cone face 70 cams the lug 88 but a short distance from the driving shaft, yet the, end of the arm 85 serves to move the stud 65 all the way from the rear of the slot 61 to the front of said slot. :The parts will now be in the osition indicated in Figs. 5 and 7.

a noted from an inspection of the firstnamed figure that the link 63-will now be engaged with the operating lever 58 nearer the fulcrum 59 of the latter than in the first instance, so that when the forward end of said lever is swung upward during printing operation in a manner heretofore explained, it will carry the ribbon to a greater height than when the stud 65 is at the rea-r of the slot 61. As the printing keys ropemt d the switchingmember 69 will rotate with the power shaft and the circular face 71 will turn in contact with the lug 88. The stud 65 and the actuating link. will consequentlyv be maintained at a fixed and predetermined disto present t a lower stripe zof the ribbon to the types. The pathsof the type impressiopls will be in a straight line longitudinal of sai' stri pla ph be ng represented by the reference b wardly about its pivot 64 until said link reaches the position shown in Figs. 1 and 10 while at" the same time the arm 85 will be swung rearwardly about its pivot 86 to the arm. 85 and link 63 so positioned the type im ressions will again follow the path a.

- t will be understood that while the hither to describedrelation between the switching member 69 and the driving shaft 461 is maintained, it is only necessary, when it is desired to shift from the black to the red printing field, to shift the driving shaft 46 iii the direction of the arrow in Fig. 4 b pulling out 66 the right-hand ribbon winding "andle 52'or It will tance from the fulcrum 59 of the operating lever and the forward arm of the latter ,will be swung u ward at printing operation so as and parallel with the path -a, said to the position indicated in said figures. With thepushing in the left hand one. And at any time thereafter it is only necessary to reversethis operation in order to change back from the red field to the black field of the ribbon. With the locking pin 76 engaged with the notch 7 9 in the driving shaft, however, it mav happen that while writing on the back field, the ribbon windin on the left "hand spool and off the right han spool, said ribbon may unwind entirely from the right hand spool, thereby eausin an automatic shift from the black field to fire red field. If at this stage it is desired to continue writing in the black field, the knurled finger piece 83 is pulled outward to the left, until the forked member 80 acts on the switching member 69 to slide the latter'leftward along the driving shaft 46 until the locking pin 76 engages with the notch 79. The parts will now be in the relation indicated in Fig. 8; A'com' arison of said figure with Fig. 6 will show t at the actuating link 63 is in the same position in both, the draw spring 66 acting to ull the link 63 to its rearmost position w en the switching member is drawn leftward out of contact with the lug 8 8 of the rotary arm 85. As long as the locking spring 76 is maintained lIl engagement with the notch "79, the, to and fro sliding movement of the rock shaft 46 will fail toshiftthe switching member 69 far enough to contact with thelu'g 88,

so that the link 63 is maintained in rearmost position and the W e impressions will follow 'a course back and orth along the path a" no matter how many times the longitudinal feed of the ribbon may be reversed.

When it is desired to restore theparts to normal position the slide rod 82is pushed'inward by means ofthe finger piece 83 until the forked member 80 'causes' the switchin member 69 to slide back to first position wit 1 the locking pin 76 in engagement with the notch 77 .after which any of the operations hitherto described may be performed.

. In order not to complicate the description v of the invention proper, the means for automatically reversing the longitudinal feed of the ribbon has not hitherto been described. The preferred means, as-heretofore stated is explained in detail .in. the patent to Felhel- 11 and GabrielsonNo. 703,339, and it is thought sufficient at this time to describe the reversing mechanism briefly, reference being had to the said patent for-a fuller description.

Referring now to Figs. 12, 13 and 14 of the drawings of the present application, 89 designates an'elbow lever pivoted to the under side of the right hand ribbon spool 36 and for the greater part of the time retained in the -position indicated in Fig. -13 by folds of the 12 that the partsare'so positioned that the ribbon is winding off the right-hand spool and on theleft-hand spool. Until the righ t-li and 13 the under side oi the ribbonspool. e theiribbonihas been completely unwound I 30 engages withthe worm 99.

Q 45 actuponthe sli has l ".bow-lever 89 serves to retain in non-working ipositiorra cain' plate 90- slidably secured to When ifrom the spool it releasesthe upright'anu of -th.'e elbow lever 89,thereby permitting the cam-plate 90 to slide vertically'downward to ;th.epositionindicatedin Fig. 14, in which polo sition the-cam face 91 is adapted to engage an m qn'ightpin 92 secured at one end of a-hori- 'Zontal lever 93. "The other end of the lever .9,3 is normally impelled rcarwardly by a spring 94 soas'to contact with and hold in i 1 5 rcarmost-position the upright arm 95 of a .slide rod96 wl'iich is constantly pressed for- ,iwardb a coiled spring 97. The rear' end of qthe Slh e rodisbentand terminates me for- -wardlyeXtending trip pin 98which normally is opposite to, but out of engagement with, a worm 99 fixedly secured to the driving shaft .46. As the right-hand spool '36 continues to rotate after the cam plate 90 is slid down to the position indicated in Fig. 14, the cam face 91, acting upon the pin 92', cams the horizontallever 93 against the pressure of the s win 94 tothe position indicated in Fig. 12, t iere y allowing the slide rod 96 to be moved v forward by its spring 97 until the trip pin 98 I g-ageinent takes place the driving shaft 46, as .;it is rotated during the operation of the machine, will be wormed along to the right until i -the right-hand driving pinion45 meshes with it'sassociate pinion 44 and the corresponding left-hand pinions disengage, thereby reversing the lon itudinal feedof the ribbon. As theribbon egins to wind back on the ri hthand spool it will press the upright arm of the I elbow lever 89 against the spool core, restoring vsaidle ver, and with it the cam late 90, to the position indicated in Fig. 13. vhen the cam plate 90 is moved upward it releases the horizontal lever 93, ermitting the latter to again d: rod 96 to push said slide rod rearwardly and restore the trip pin 98 to nonworking position, the spring 94 being strong enough to overcome the spring 97.. It is to be understood that the left-hand ribbon spoolis provided with a similar train of mechamsm which will operate in a similar manher when the said spool is emptied of the ribbon;

l It willbe noted that'by my present inven-] tion, I provide means for throwing the ribbon vibrator any one of a plurality of predetermined, distmct distances so that a type will ,strike at :any one of a plurality of predetermined, distinct points'in the width of the ribbon. IQ-The pathofi the type' impressions will be lengthwise of one" portion of the ribbon until the longitudinal, feed of the ribbon is lieversed, whereupon, normally, the ribbon will shift widthwise and the path will ch 1 136 one parallel with the first path and l spool is emptied the horizontal arm of the el- After this en-p bon widthwise, and means for rendering said ribbon revers ng means for bination of a pair of ri wise tr the ribbonf along another portionof t, Means are also rovidedfor pneventi' widthwise shift or c 'ang'e of path when. the

lengthwise feed of the ribbon is reversed, and

when such means is operated the, type impressions will be confined to a single 'ath'.

In the machine illustrated'in the rawi the *relation' between the platenand the i$- bon vibrator is not affected by a change of case, but I desire to be t; derstood that my invention is not limited to constructions wherein the relation between, e platen and theribbon vibrator remains unaltered when case is changed." Furthermore, while the drawings illustrate one construction "of mechanism or automatically moving theribbon to cover the printing point during operation and for thereafter m'ov' said rib-L v bon to uncover the'pn'nting point, it is tobe understood that other means of accomplishmg this result may be em loyed. Wherever in the claims it is stated 1; at the vibrator or vibratorycarrier is thrown to the printing point I desire to be understood as meaning that the vibrator is'moved'so as to cause the ribbon to cover the printing point on the platen. P
