@MWTM Int/672607. WM Svb wg o torney fz re as a; basis, I place upon-the platen arbor '13 outside the carriage frame 12 the .10 &

toothed wheel 11, attaching the same fixedly thereon by means of the key 44. I next attach uponthe end of the carriage-frame 12 the axle-pin 21, and place upon the pin the composite rotary part shownin cross-section I in my Fig. 2, comprising the bushing 12, the

rotary part 6 fixedly borne thereon, the

toothed wheel 5 rotatively adjustable upon the bushing and the said part 6', and the two annular parts 6 and 6, both attached to the toothed wheel 5 by means of the pins 43. The part ,6? is supplied with interto engage with the tooth 17 on the lever 18,

"which rocks upon the fulcrum 53 within a recess 37 cut to-receive it in the part 6, the recess being rectangular in form, and of a width suflicient for the rocking lay therein d in position as shown by thespring 35, attached to ,the part 6 'by thepin 'or screw 54; and when n positionit acts lockingly upon the part 6? so that the toothed wheel 5 and itsattachedj parts cannot change their rotative position relatively to thepart 62 and it also acts bindingly upon the part 6 as regards The part 6" has upon it two projections, the one being the pin 20, stationed near the periphery as shown, and the other the end of the lever 18, stationed away from the periphery, or toward the axis. The toothed wheel 5 is supplied with ya projection, also, lettered 1 1, a working view of which is had in Fig. 3 (and Fig. 4)

i jand its periphery is not continuous, but has a gap 75 in it, some of the teeth being cut I away, the s aid toothedwheel being a mutilatdgeai. The carriage frame 12 has jour- -naled upon it the rocking U-piece 80 by means of the rock-shaft 81 as shown best in Fig. 5, the shaft extending inwardly toward the center of the platen, where it is supported by the carriage frame extension 82 attached to the front rail of the said frame 12. This inner end of the shaft 81 bears the fixedly attached lever arm 83, the end of which beroller-wheel 85 as shown; and for a track 'comes an axle havin an axis at right angles to the axis of the s aft 81 with which the lever rocks. Upon this axle I place the forthe wheel I attach to the main frame 41 of the machine the track 86 to extend from end to end of the said main frame, that is to say, parallel with the platen and with theusual carriage tracks. The bed of the track bends upward at an operatively suitable p mt into the m u d or r 87 th lope of which maybe quite gradual, and then downwardlagain to track level. The U-lever 80 .upon' the outer end of .the shaft 81 is given its form in order to bring it into operative relations with the projection 14 upon the outer'face of the toothed wheel 5. It likewise terminates in an axle or piii 79 having bolts 64, and from this I project into thepath of the prgjection 14 the brake-shoeor friction-stop 1 using the 'pin 65 and the spring 66 to carryand position the same, and the support 63 to cooperate therewith and.steady'the pin. I-also' station upon the carriage frame 12 the pointer orindex-guide 34. The plateyfarbor 13 has the usual twirler or finger-wheel 60 on the end thereof.

The action oft-he structure thus far described is as follows:' The sheet may be imagined as completed, and the toothed wheel.

5 as being stillin mesh ,with the toothed wheel 11, the broken peripheral portion 75 lying either backward or forward from the engaging point:v The sheet will now be twirled out of the machine in the usual way,

by turning the platen forward, and another sheet entered and advanced into a printing position. This forward movement .of the platen will havebeen communicated to the toothed wheel 5 through the action of the toothed wheel 11; but sooner or later the broken or toothless portion 75 of the periphery of the wheel 5 will ,have been brought around into the position shown in Fig.1, the wheels will have passed out of mesh, and the brake-shoe 15 will have brought the now disengaged wheel 5 to a stop, by'acting upon the projection 14. The first,line will now be printed; and as it is not customary for good stenographers to run over upon a'new sheet a short line at the end of a paragraph, it will be a line of a.

end of a lever-arm on the shaft 81, the shaft will be correspondingly rocked, and the U- lever 80 with it, thus pressing the end of the pawl 78 operatively against the projection 14. The wheel'5 will thereupon be turned forward past the gap in its periphery and into mesh with the wheel 11. The spacing lever 51 will now be used to space the platen forward for the printing of the second line, and as the toothed wheel 5 is now in mesh with the toothed wheel 11, it willthereafter turn synchronously'with the platen "during two r v l ions of the platen more or less,

The means whereby the machine is rendered inoperative are describ ed thus; Upon J the carriage frame .12 andfprojecting. out wardly therefrom is the axle. .7, bearing journaled thereon the elbow lever 71., i The 5 upper arm" of this "elbow-lever projects into The arm'72' the path of the .pin'2O on the part 6 before described, whereas its lower arm carries the pin 33; Between the two ends of the carriage' frame '12 and journaled the-rein both at one end and the'other is'the rocking shaft 57, which has. fixedly attached thereto at either end inside the frame-ends 12 the cranl'r-levers; '52. *These levers 52 in turn carry attachedfixedly upon them by the ends thereof thehorizontal-bar 3, so that the bar 3 throughout" its entire length will swing in an are upon the shaft 57 its axis,

the two lying parallelthe one to'the other.

connected with the elbow lever 1 before 'tached -to' the endofthe carriage frame 12 named bymeans of the pin 56 onthe said crank-lever, the connecting-rod 53, and the pin-33. The elbow lever 1 and its connected parts may be so balanced as to come to the position of rest as shown. I now journal in the two ends of the main frame 41,-by

means of the axles 48 and the appropriate bearings therefor, theqrocking gate 50 havlng attachedthereto; about centrally of its 'length'thepiece 47, provided with thepinv 46,=the saidpin 46 when-thus attached to the gate be ngineifect a crank-pin upon the same arbor therewith. Fromflthis pin 46- extends the connecting-rod 36' upwardly and bearing 2, fitted uporithe parallel bar 3 in such a manner that the horizontal bar 3 can .slide'therethrough from end to endwithout greatfriction as the said Ibar moves'b ack and forth: with the carriage, the bearing 2 rema ning in a stationary-position the while,

u about midway between the ends of the main frame 41. The guide pieces 49 assist .in v holding the rod 36-and its bearing 2 against atransverse movement with the carriage. I show them attached tothe stationary track 40, which is attached in turn at either end to .the main frame 41, andforms practicallya part thereof. -When it is 't-imeff0r the machine to be rendered inoperative, the pin 20 presses-upwardly against the lever 1, and the shaft 57 is thereupon rocked. together with its attached arms 52, thus lifting the 'horizontal bar 3, and through the connecting rod 36.,and its sleeve-bearing 2 raising the gate 50 into a position approximately vertical- This gate, is tobe stationed as shown :underneath the battery of levers connected underneath these several levers, it will no longer be possible to depress them in the usual manner, but they will be locked 1 against the action of the keys 59 and 39, and

- to render the machine inoperative.

tary I will now describe more particularly the use of my invention. Suppose I desire to print a page thirty-two double-spaced lines in length: I first unlock the rotary part 6" from its connection with the toothed wheel 5 and its attached parts by operating the lever 18. This lever 18 may be so stationed that its projecting end will lie directly under the pointer 34 at the moment the pin 20 releases the bell-operating lever 69. Bringing the lever 18' around under the pointer 34:, I hold it. there in its unlocked position, and turn the platen 10 until the indices 6" pass under the pointer as far as the numeral 32. I then release the said lever, which forthwith locks the several roarts named to rotate as a unit. My signa bell will now always ring when the platen is spaced forward for the printing of the thirty-second line, and my machine will always be rendered inoperative if the laten is then spaced forward for the printmg of an additional line, the pin 20 acting first u on the lever 69, and then a linespace ater upon the lever 1. If for any reason I wish to add further matter to my page, I can always do so by turning my platen forward a line to release the lever 1, and then backward into the printing position. It will readily be seen that as my lever 18 sustains a constant relation rotatively to the part 6, and consequently to the indices 6", the numeral 1 of the said indices 6 may be positioned to lie immediately above the projecting end of the said lever 18, and the other numerals in the series at peripheral points related thereto; in which case the bell would always ring when the numeral 1 of the indices 6 came opposite the pointer 84. If therefore the signalin means be adjusted to operate when required, the inclices 6 will always indicate cor'iperatively therewith the number of lines between the current line position on the sheet and the line-position at which the signal is set to be given, whatever the current line position may be. i

In my Fig. 4 I show a modification of my invention, for the purpose of showing that the toothed wheel 5 can be rotated around into mesh by means of another part used in the usual operation of the typewriting machine, in this case the line-spacing lever 51, though almost anv part used in the nor mal printing or positioning of the sheet could be employed instead, or a part having no other use whatever. The line-spacing lever 51 is here shown as fixedly attached to the rock-shaft 77 journaled upon the carriage frame 12; and in addition to the usual line-spacing pawl and its operating lever, the cranlelever 80, bearing the pin 7 9 and the pivoted pawl 78, is attached thereto. The wheel 5 pass-es out of mesh as before; and then, after the insertion of the new sheet, the first line is printed. The spacing lever 51 is now used, and the pawl 78 is at once driven forwardly upon the projection 14, turning the wheel 5 into mesh. As the first part of such a spacing stroke is usually idle as far as its effect upon the platen is concerned, the wheel 5 will be in mesh before the platen begins its movement, and will then move forward therewith as before. I show more particularly the trackand-roller means of bringing around the wheel 5, for the reason that in some typewriting machines the platen is not spaced forward by means of a lever 51.

It is to be noted that the pawl 78 will pick up the projection 14: at any point within its stroke, wherever that projection may chance to be, and carry it forward to the end of its stroke, that is to say, into a contact operative position. It will be perceived that I have therefore in this specification disclosed two separate means of bringing an o erative member into a constant operative position, the first being by means embracing a broken periphery, and the second, by means embracing a pawl and projection or monotooth. I have shown these means as acting cooperatively, the one with the other; but in my co-pending application filed December 5, 1912, Serial No. 735,108, I show the principle of the one used and not that of the other. A monotooth ratchet-wheel and pawl could be used to bring an operative member into a constant starting position from'any of its several secondary positions.

The series of indices 6 and 6 are preferably carried upon a periphery as shown, but it is not in all cases essential that they should be peripheral. I show them as controlled or operated by a rotary part, but it is not in all cases essential that they should revolve upon an axis as shown, nor that the part controlling them should be rotary. Markings or symbols other than numerals may be employed, and units other than the line unit. It is not essential that the pre oise means of adjustment between the part bearing the projection or monotooth M and the part bearing the pin 20 herein shown should be employed. The indices 6 may be used alone, without the indices 6", and the indices 6 alone without the 6 indices, or both series of indices may be omitted and the bell signal alone used, or the means rendering the machine inoperative alone, or

. either itfor the bell signal'used alone with constant initial or starting position are known and commonly used in other arts, al-' mostany of which would be the equivalent of the means employed in my mechanism, and furthermore-that the, means disclosed herein are capable of; taking many forms."

The invention is'not restricted to the use of friction means forch cking the movement of the mutilated gear. Other means than the pawl means shown can also be employed Ufor rotating the said wheel forward into reengagement, some of which are specifically describedby me in myapplications filed Demcember 5', 1912, aforesaid and December 16,

1909,.Serial No. 533,355.

-' The stroke of hepawl 78 against the monotoothprojec tion 14, whereby the'wlieel 3 1 5 is rotated forward into engagement during the printing ,of the first'line, or at a moment I having a definite relation to, the printing of the first line, is preferably given as shown,

but it is .to be noted that it coiild just as wellbe givenby another part usedin print Y ing the first line, or inpositioning' the sheet .before or after the .said printing operation- :235

and I- illustrate'inFig, ,4 how the line-spacelever for instance nay'be, used in'this duty.

J The preferab e form 'of invention for machine's having the: line-space-lever con -veniently' stationed would be that shown in' Fig-4 ;-but for those in which the line-spacelever; is absent, that shown in Fig; 1 would be My general invention has as its pith the fact that I show means whereby an operative part, preferably rotary, controlling an in.- dicating or signaling means, is brought into .aconstant-initial or starting position before or by thetime the sheet is brought into a relatively constantline position, and then is given a movement constant with that of the sheet.

:' "AS more specifically disclosed in theprest cut application, I show means whereby a rotary member is made to revolvewith the platen through a toothed connection therewith, means whereby it is brought to a stop at a constantrotative point through a break in the connecting means, specifically a break I in the toothed periphery of the gear wheel,

cooperating with a detaining means, specifically a friction-stop or brake,and means whereby it is then spaced forward into connectionwith the platen by the action jot parts in the typewriting machine, specifi cally the action of a part stationed upon the main frame upon a stationed the carriage, the said partsyacting specifically upon a reciprocatingmawland against a mo-noto'oth projection in- 'CQDDQCUOI). with the 'mutilated gear; It is: to .e, Il0t Bd=' in this omitting the platen 'connection'; or I might have-used ap'awl -and-r'atchet mechanism operated by the action ofiapart stationed on the main frame upon a part stationed on the carriage to rotate myrotary-.member, omitting n'otonlv the platen conection but the broken eriphery.
