To all when tit mJaycOn erIt:
Be'it known that I, FRAKZ .X fWAGis ian,
a citizen of the United Statea'residing'inthe borough of Manhattan, city, county, and
State. ofNew York, have invented certain newia'nd useful lm rovementsin Typ'e wrivin'g Machines, ofw. ich'the followingisafull,
. clear, and exact'description.
. "My invention relates class of writing-machines noWn as visible Writers, inwhich it is, usual tofvibrate theribbon to cover and uncoverthe printingpoint at each type impression, whereby the,
type is enabled tomake an impression through to feed the carriage.v The striking of the or.
then'is struck another which it is desired to accent.
I the ribbon and' the latter. is immediatelyand' automatically withdrm'm,sov as to disclose the Written letters.
The invention relates particularly to means in machines of this class for accenting or un- 1 derscoring letters.
Oneof the t yes is pro-'. videdwi'th a suitableacc'enhmar and the key controlling type-key. omits to cause the usual letterefeed itng'moveinent oi the paper-caniage so that by striking the accent-key firstandlthen the ordinary key the letter anditsac cent are-u caused to register properly upon the Written sheet. Such an .accent type-key is. some-'- times calleda *blank? key, because-it omits dinary type-key of course causes'the carriage to feed as usual, so that the letters may ap- 'pear'in proper sequence upon the page; I
In the class ofvisible .Writer'sine ans com-f 'mon to, all of the type-keys areus ually-proe vided' for both feeding the carriage and v'i-; brating the ribbon ,to cover the printing? point. Usuallythe keys are adapted-topperate a universal baryw hichfin some; kinds of machines is. in the form ci a curved" bar. mounted just in rear of the t y e-bars and movable rearwardlyby meanslof eels formed upon the type-bars, and 'by means of said universal barlthe ribbon is'vibrated and the carriage-is fed. Thegist of my invention resides in causing'the. accent-key or blanklkoy to vibratethe ribbon without fiee din the cab, riage, so thatflthe accent-markr'nay e prop erly. printed whilethe carriage is held. until tiontothe accentrnark,j.

Saidlockis no'rmally idle, but is capable of being set to .efle'ctive position by the said accentekey. Provision is also made dinary ty e-key as well 'key, to re ease said lock, may feed as usual.-
embodies'certain novel features of constrxiction,;.- arrangements of parts, and combinationsof devices, as wr concluding claims.

Figure 1 represents a transverse vertical sectionalvie'w of a machine embodying, my invention, th'e'fsection being taken about centrally through the machine from front to. rear controlled. b the accent type-key for preventing the" ceding of'the carriage. Fig. 3 is a side; view ofLthe same. with parts broken away for. the purpose of better illustration. 41s a skele'tonview similar to Fig. 1, but showing one typebar-,(theone that carries the accent-type) in printing position, its key depressed,and associated parts moved corre spondingly from-normal position, an ordinary type-bar being also shown in normal position. Fig. 5 illustrates the locking dog or detent in effective position after thereturn of I accent-key to normal position.
for enabling any subsequently-operated oras the usual spacingsov that the carriage 1 In the accompany ng drawings my irivented, thou h obvi-- visiblej in detail of constructionforthe adaptationofi eration of the universal bar. A lock or detent controlled by the accent-key prevents the usual returnfmovement of the universal bar andc arriage-feeding mechanism, so that the carriage is not released .for a' feeding "The-illustrated form of the invention also i v75v b'e'hereinafter decl'ribed, and particularly pointedout in the thereof, the parts being-"in normal position. Fig; 2 is a detail plan view of a lock or detent In the several views like parts are identified by like signs.
1 designates the framing of the machine, in which is mounted a segmental plate 2. plate 2 carries a pivot-rod 3,.upon which the type-carriers or type-bars 4 are pivotally mounted. Each of the type-bars! is connected to a bell-crank 5, pivoted at 6 to the framing of the machine and pivotally united to a key-lever 7, as indicated at 8. The keylevers 7 are provided with the usual fingerkeys 9 and are pivoted at 10 to the framing of the machine. Each of the type-bars is provided with a heel 11, which abuts against a universal bar 12 during the movement of the type-bar up to the printing-point, whereby a rearward movement is given to the universal bar, which usually is formed or shaped to conform to the curvature of the type-bar system, whereby all of the type-bar heels may operate the universal bar. ,The carriage-feeding mechanism or escapement is connected to this universal bar, and each complete movement of the latter causes the platen-carriage 13 to be fed one space in the usual manner. of any type-bar the universal bar is moved During thev printing stroke back, as at Fig. 4, and during the return movement of any of the ordinary type-bars said universal bar returns to normal position, the movement of the universal bar thus being reciprocatory. In the present instance the carriage-feeding mechanism comprises a tanected to crank-arms or links 15. Said table carries feeding-dogs 16, which successively.
or alternately engage a rack 17, mounted uponthe carriage, so as to effect an escapement or feed of the carriage at each reciprocation of the universal'bar-that is, at each,
complete lateral movement of the feed-dogs to and from their initial position. It will be understood, of course, that the carria e is fed upon the second or return stroke of t e dogs and ,universal barthat is, that the carriage remains motionless during the first or rearward stroke of said parts. The arms 15,
hereinbefore referred to, are rigidly connect- 'ed to a rock-shaft 18. A forwardly-projectingarm 19 is also secured to said rock-shaft, said arm and forward extension-20. Against-the under' side of said extension is adapted tobear an upwardlymovable crank-arm 21, the latter being fixed upon and projecting .rear- ,wardly from a rock-shaft 22, which is mounted in the framing of the machine and from which extend forwardly spacing-levers '23, carrying at their forwardends the usual spacing-key 24. B y depressing the spacingkey the arms 23 are carried down, the arm 21 elevated, thereby through the arm 19 rockin the shaft 18 and the arms15, which draw back the table 14, together with the; dogs 16,
This.
being provided with a downward feeding dogs, and hence prevent the carriage and upon relief of the spacing-key from pressure the parts return to normal position, during which return movement the dogs cause or permit the carriage to advance one step. Said arm 19 is provided with a, slot 25, into which takes'a pin 26, the latter projecting from a crank-arm 27, that is rigidly connected to a rock-shaft 28, and the latter is provided-with ribbon-feeding arms 29', each of said arms being provided with a pawl 30, 7 5 that cooperates with a ratchet-wheel 31, and each of said ratchet-wheels being connected up in a suitable manner to the ribbon-spools,
upon which the ribbon 32 is carried. Said ribbon-spools are designated as 33 and are mounted forwardly of the platen 34 in such a manner that the types may strike through the length of ribbon that reaches across in. front of the platen from spool to spool. The writing is visible asit proceeds, because after 8 5 each impression the ribbon drops. For ele vating and dropping the ribbon at each type operation "a slide or vibrator 35 is employed,
said vibrator being just in front of the platen and in the vicinity'of the printing-point and 0 carrying the ribbon up and down. Normally it stands in its lowest position, as at Fig. v1;
but when any key is operated it is lifted so as to interpose the ribbon between the type and the paper, aswill be understood from Fig. 4. 5
Said vibrator is controlled by an arm 36, pivoted at 37 upon afixture andprovided with a pin 38, whereby it is vibrated, said pin 38 engaging a slot 39, formed in an arm 40, u standing from the table 14, whereb the back- 1 00 Ward and forward movements 0 the table cause the arm 36 tovibrat'e, and thereby lift 7 and drop the ribbon vibrator or carrier 35. As before explained, said table 14 is connected to the universal bar 1 2, and hence the uni- 1o 5 versal bar effects the lifting "of the ribbon at each type stroke. v v So much of the mechanism as has thus far been described constitutes mechanism of the well-known Underwood type writing mar10 chine and is well adapted for use in practicing my invention. I will now roceed to describe. the remaining devices 0 the mechan-' ism, with which cooperate the devices already described, to carry out the purposes of I 1 5 my invention. Said remainin devices comprise principally a detent or whereby the accent type-key (or blank key) may prevent the full return movement of the carriagex 1'20 from feeding; but I do not wish to be understood as intending to mean that my invention consists in merely addm these few remaining parts, since so far ast e broad featuresof the invention are concerned it is immaterial whether it be practiced in an Underwood or some other type of machine, and all of the. carriage-feeding and ribbon-vibrating mechanism may be varied widely within the scope My invention,

The free or forward end of this locking-dog is adapted to cooperate with alock ing-abutment 10,
with a notch l. tains' the locking dog above said lockingabutment, Fig. 1, so that ordinarily there is nothing to prevent the rocking of the shaft 28 or the corresponding movements of the universal bar. 12, and hence there is no interference with the feeding of the carriage unless the blank key is operated.

because of' the engagement of the lockingdogc with the nose m of the locking-abutment is, Fig. 5, which holds the parts It, 28, 27, 19, 15, i4, and 16 from returning to nor mal position. The depression of the blank key having made the imprint of the accent anism in the direction of the arrow 1: inthe manner hereinbefore described, and this movement will cause-the locking-dog c to be freed from the nose m of the lockingabut' me'nt, and the locking-dog being thus released is elevated to normal position by its springf, it being understood that at this time the spring 2' is not under tension and affords no resistance to'the u ward or return movementof the lockingg to ineffective position. It will thus be seen that a movement of-the blank key causes the ribbon to cover the printing point and an imprint of the accent-mark to be made through the ribbon upon the paper or platen and simultaneously locks the carriage-feed mechanism out of operation and that a depression of any of the writing-keys will thencause an imprint to be made in the same space that the accentmark has been imprinted, or, in other words, in proper register with the accent-mark. At
the same time an automatic release of the feed mechanism will be effected, so that the operator may proceed with the writing in the usual manner. It will'likewise be observed that the'locking of the feed mechanism out of operationduring the imprint of the accentmark and the character which 006 erat es therewith and the rele'asing'of the fee mechanism immediately after such character is written is effected automatically. It will also be oberved that movement'of all parts of the-carriage-feeding mechanism is'effe'cted. when the spacing-key 24 is depressed. Thedepression of the spacing-key causes the arm 21 to be elevated, thereby shifting the parts of the carriage-feed mechanism inthe manner described by reason ofthe, cooperation of the arm- 21 with the extension 2Q.
I While I have described with considerable detail a construction embodying my invention, I am aware that various changes may be made without departing from the spirit of my invention. Thus While I have shown the locking mechanism so constructed as to bei o eratedin part by the mechanismlwhich directly effects the feed-of the ribboni but which nevertheless controlled andoperated.
by the feeding mechanism, it is obvious that i this movement of the parts may be effected from any portion-of the carriage-feed mech anism.
