Application am June 15, mos. smn No. 488,577.

To all whom it may concern:

Be it known that I, WiLuaM JONATHAN Nmoio. a citizen of the United States re- -siding at Madisomiu the count of 15am! and State of Wisconsin, have invented a new and useful Improvement in Type-Writing Machines, of which the following is a specification.

The resent invention is a branch or divisicn n that more broadly claimed'in my divisional application filed March 30, 191), Serial No. 687.463, and also is included within the generic invention which is described and claimed in my co-pending a plication filed April 20. 1908, Seria 0 428.212.

The objects of my invention are first, to give the operator of the typewriting machine a signal whereby he may know that the bottom of the paper sheet is near; and second. to indicate to him the distance remaining to the bottom of the said paper sheet from the current printing point, during the later sta es in the progress of the sheet. I attain tiese objects by the mechanism illustrated in the accompanying drawlogs, in which-- "igure I is an end view of a aim is embodimentof my invention; Fi I is a view of certain details thereof; ig. III is a front view with the end of the carria in vertical section on the line A A, Fig. with the paper sheet removed and with the indicator 6 turned one-fourth of a revolution in order to bring the orbital paperfeeler 8 into a position where itv can be more clearly represented: Fig. IV is an end view ofn second embodiment. view of certain portions 0 the same, in section on the line (7 .l. of Fig. IV.

Referring to the several figures --A 01'- tion of the machine frame is indlcat at 10, and at l is shown a portion of the usual transversely-moving carriage-frame, in the ends of which latter is journaled the arbor 19 of the platen 11, as usual. The platen is rotated in practice by line-space mechanism not necessary to be shown herein.

At 8 is shown the paper-table, .and at 81 the curved paper-fingers for holdin -the paper to the periphery of the dplaten. eae parts may be 'of any approve t pa.

lliinventimt provides an in icstor that Fi V is a front n'ormall .revolves synchronously with the laten, ut which under conditions of intererence' may remain stationary at a constant. point in its revolution until the end of the paper sheet reaches a certain constant distance from the current printing point, the indicator thereupon resumin its revolving movements, and indicatin t enceforth the relative position of the on of the sheet.

The indicator may take various forms. In Figs. I and III will be. seen, at the end of the platen, a friction-wheel consisting of a passive revoluble section, an active revolving section, and means for adjusting the tension between the two. By passive I intend to convey the idea that the part which I term a passive revoluble section is the recipient of force by which it is propelled, z'. e., it is the driven part of the said friction-wheel. B active is intended to be expressed the i ea that the active revolving section acts as the driver in communieating movement of revolution to the section rst mentioned. The passive section is the indicator 6. The active section is shown as a collar 13, formed with a radial flange 13" and fitted upon the platen arbor 12, and revolving as a unit with the platen 11; and the passive section consists of an annulus mounted upon said collar and making contact bv the inner side face thereof with the said flange. The said passive section sustains lig t frictional en agement with the active section throu h t 0 normal friction of the wearing our aces, and through the adjustable tension im nrted by the pieces 7 and screws 9. The rictional engs ment is intended to be extremely light-on y sufticient to cause the passive section to turn simultaneously with the platen under normal conditions of non-interference.

The means whereby the indicator is stopped at a constant point during certain stages in the progress of the paper sheet, may be most eels: y exfilained b making reference first to Figs. II, and II. The indicator here beats the radial extension piece 82 and the laterally-extending rodtlte orbitaLpaper-feeler 8. The pa r-table 8 is suppli with a laterally e'xten ing slot 4. In the absence of the sheet 2, paper feels r 8 revolves without interference in its orbit 5, passing the paper-table through the till slot 4, its path thus intersecting the path taken by the aper-sheet- 2 down the face of the paper-tab e 8. When, however, a sheet of aper lies upon the paper-table, as shown in ig. I, the slot 4 is closed thereby, the movement of the paper-feelc'r is arrested by the sheet, and the indicator bearin said paper-fecler is brought to a stop un ii the en of the paper sheet passes the slot. In the illustrations I show how the indicator may be made to bear the orbital paper-feeler in duplicate, in order that a paper-feeler mav normally pass through the slot 4 at car half revolution of the platen, the peripheral indices being duplicated to correspond. For an but. small work like library card writing t e duplication would not be made.

The advantages of using a aper-feeler of the form shown in Fi s. I, Ifi III, in the case of a mechanism emp oying an indicator or controlling member similar to the member 6, are, first, that thereby sheet-insertion is facilitated, the paper-feeler never being :11 a position to obstruct the entering of a new sheet into the machine. If in some chance position of the mechanism the paperfccler s ould lie too near the paper-table to permit of sheet-insertion between it and the paper-table, the sheet could be inserted above the paper-feeler 'ust as well. The paper-feeler will eventually come into sheetcontrolled position whatever its starting relation to the sheet. Second, in case of backing-up movement after the release of the paper-teeter by the sheet, the backing-up mttom edge of the sheet will encounter a minimum of obstruction from such a paperfeeler, if indeed any at all, and even if the sheet-end is picked up by the aper-feeler it will be released almost instant y thereb the speed of the backin -up paper-feeler ein greater than that. o the platen surface and t ierct'ore than that of the backing-up sheet, as will he understood. Third, when the mechanism is backed-up from the position of arts shown in Fig. I, the paper-feeler un er the actuation of the baekwardly-turning platen recedes from contact with the sheet, so that the most delicate sheet may be backed up at any time without danger of clogging. Fourth, the broadside presenta tion to the sheet of such a pa er-feeler constitutes in some of the embo iments of my invention a distinct advantage, since thereby the pressure is more evenly distributed upon the sheet. Sacha construction also a ords a convenient means for extending the workin ortion of a paper-feeler inward towar t e center of the sheet past the rinting margin as far as may be desired.

here are other advantages in the construction shown for-a mechanism of this character. It is not essential that such a paperfeeler be given orbital movement intersect- 1,oos,es 1

ing the papenpath, nor is the portion of my invention invo via the form of the paperfeeler necessarily Iimited to the use of a paper-feeler of the exact type or construction shown.

It will be borne in mind that the interference of the paper sheet stops the indicator at a constant point in its revolution, or at a plurality of constant points. It follows that it is iven movement thereafter always from a re atively constant startin point. The pointer or index 34 (Fig. III) is attached conveniently to one of the paper-fingers 31. I can mark with the indicating mark 0 that point on the periphery which is opposite the pointerwhen the art 6 is in its arrested position. The mar 0 must obviously remain opposite the pointer until the memberti resumes its revolving movement. As the member 6 resumes its movement the moment the bottom edge of the sheet clears slot 4, and as it then moves forward simultaneously with the laten, and thereafter withthe sheet, the s eet being fed by the platen, it is plain that if I mark the next stopping point 9 to correspond with thedistance at that moment from the printin point to the end of the sheet, which we wfil say equals nine double-spaced lines, I can mark the succeeding stoppin -point 8, and so on down to 1 and the en of the sheet.- Or, if it be desired to space by single lines, the first stopping-point after 0 could be marked say 19. the next 18, and so on down to 1. Or, other indicating units could be used. I have now a means of informing the operator of the exact extent of his remaining bottom margin at any point within the range of my device. I could mark my periphery to indicate the distance to the last line intended to be rinted upon the sheet, just as well.

n indicator marked as I have described satisfies both the objects of my invention in what I regard as the most perfect manner. but I consider my invention sufliciently br ad to include within its scope various known types of indicating or signaling devices, either visual or audible, which may prove suitable and convenient for use in practical embodiments of the main prineiples of the invention. I regard the murin surface as constituting an odor uate signa l to the operator; and in addition it informs him of the exact position of the bottom of the sheet.

Itis to be noted that the passiverevoluble. section of the indicator may vary more or less in character and construction in 'prao tice, and the means and mannerof actuating the same may vary. In Figs. I, II and Ill l have shown the same in the form of a ring, "annulus, or, as it may enericallv he termed, band. The radial thickness of the said band mav vary in raetice.

In Figs'lv and V t e friction-wheel of u the pa .ihe said lateral which the indicator constitutes the passive section 6 is divided verticall upon the friction line 35-35, instead of orizontally, and the tension is adjusted differently; namely, by means of the screw and t e spring 24. The indicator here is shown as revolvin upon an axis 29 separate from that of the p aten. The said axis is constituted by a laterallv-extended shouldered axle or stud. carrie by the frame-extension or bracket 19 upon the carriage-frame 1. In order that the normal movements of the indicator may be synchronized with the revolving movements of the laten, I show the active section of the riction-wheel as a toothed wheel 28, meshing with the toothed wheel 22 keyed to revolve with the platenbut any equivalent train of parts would answer the purpose. The said indicator or revoluble member 6 and the said toothed.

wheel 23 are separately mounted to rotate upon axle 29, the spring 24 attached to the ltlll'lll e-frame 1 serving to press them into lateraFfrictional enga ement. The tension of such spring, and t e frictional engagement. are regulated by the ad'usting screw 25. as indicated above. The in ex or pointer 34 is attached to the axle or stud 29.

In Figs. IV and V the orbital paperfccler 26 may be a fixed rojection carried by the indicator; but I sliow it as pivoted upon the pin 80 carried by yoke 36 attached to the indicator. so as to be able to bend idly backward in the contingencv of a backingup movement of the per sheet. The

orbital pa ier-feeler '3 in l ig. I, intersects the path 0 the aper sheet, assing through the slot 4' in t e aper tabYe 8; and when the slot is (lOsQtl liy the aper sheet 2 as shown. the paper-feeler 26 cannot complete in movement and stops the indicator until ihe bottom of the pa r sheet passes the slot. The yoke 36 is attac led to the revoluble indicator 0 so as to rotate therewith and exn-nda inward therefrom, to furnish a convenicnt support for the paper-teeler at a distance inward (mm the edge of the sheet. The pin 80. upon which the paper-feeler in ivoted oi' hinged, is mounted on the said yoke at a point eccentric to the axis of the yoke. and provides the paper-feeler with a secondary axis upon which it has movement relative to its carrier. The movement of r-feeler upon this secondary axis in limit by its contact with the laterally-extending portions of the voke. 86. sothat it wil not completely revo ve on the pin 80. but will be stopped by one or the other of v-extending portions. Contact with one of these portions gives it the extended position shown in Figs. IV and V. in which it is etlective to en ge with the sheet, and in which it is e ective in the presence of the sheet to detain the indicator ath' here of the paper-fee er 26 like that o the 6. When the end of the sheet passes the paper-feeler the paper-feeler, no longer de tained bv the sheet, enters slot 4 in the paper-table, and the member 6, no longer detained by the paper-feeler, is given simultaneous movement'with the platen ,under the impulse of its frictional connection with wheel 23. If the sheet be backed up after having released the paper-feeler, the backingup bottom edge thereof will meet the paperfeeler and bin e it idly backward on pin 30 away from thedaterally-extendin ortion of yoke 36 that previously control e it, thus permitting free backing-up of the sheet rom a late'position. This acking-up provision is what might be termed a one-way joint, and it is not necessarily limited to a gaper-feeler having orbital movement.

acking-u from the position shown in Fig. IV is simi at to that previously described in connection with pa er-feeler 3 of Figs. 1, II and III, papereeler 26 likewisereceding from contact with the sheet under the actuation of the backwardly turned platen.

Various modifications may be made in the construction and arrangement of parts, etc. without necessarily involving any departure from the general principles of the invention.

Althou h I show the indicator as the passsive revo uble section, suitably marked, of a friction wheel, because I regard that as the most perfect form for it, it is to be understood that the claims are not necessarily restricted in respect thereof, or in respect of a frictional engagement between the indicator and the art that impels it, except in the case of tliose claims which are express] limited thereto.

Alt ough I show the interscctin parts 8 and 26 as intersecting the pntli of t ie paper sheet at the paper-ta )le 8, it is to be understood that this is not essential in all cases.

The form which my invention would preferably take depends largely upon the make of machine to which it is to be attached. That shown in Figs. I, II, and Ill, would be named first, because of its simplicity: but it would be the most likely of the forms shown to interfere with feed roll mechanism under the )laten. That shown in Figs. IV and V .wou d be the easiest to apply to machines already assembled.
