PAPER-CONTROLLER, FOR TYPE-WRITING MACHlN ES.

SPECIFICATION forming part of Letters Patent No. 763,661, dated June 28, 1904. Application filed February 15, 1904. Serial No. 193,725. (No model.)

To all toll/cm it may concern:

Be it known that I, JOHN H. ConnELIsoN, a

citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Paperi-Controllers for Type-W.riting Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. This invention relates to new and useful improvements in controllers for type-writers; and the object of the invention isto produce a tension device especially adapted for visible type-writers and provided for the purpose of holding the paper against the platen-roller and to be guided forwardafter it has been printed upon and in accomplishing this purpose afford as little'obstruction as possible to the vision of the entire printed matter.

More specifically, my invention comprises a fine tension wire or cord steadied between the ends of the carriage and stationary relative to the same and in the provision of fingers adjustably mounted on said. wires, which are provided for facilitating and guiding a paper underneath the tension-wires.

Myinvention consists, further, in various details of construction and in combinations and arnangements ofparts, which will hereinafter'be fully'described and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of reference indicate like parts in the views, in which- Figure l is a top plan view of aportion of the carriage of a type-writer platen-roller, and gage. Fig. 2 is a cross-sectional view throughthe carriage. Fig. 3 is a sectional view through the carriage, showing the stationary finger extenslon for guiding the paper underneath a tension-wire. Fig.4 is a sectional view transversely through the carriage, showing a slight modification of the tension mechanism. Fig. 5 is a similar view of a diiferent modification. Fig. 6 is a sectional view showing still another modified form of my invention. Figs. 7 and 8 are detail views showing a gravity-finger and paper-guide.

Reference now beinghad to the details of the drawings by letter, A designates a tensionwire which is suspended between the end plates X,'which form. a part of the carriage for the type-writer. Said tension-wires have flexible washers D mounted upon their ends, which project outside of the plates, and nuts E are mounted upon the threaded ends of the tension-Wires, confining the wire and Washer in their proper positions and allowing the wire to yield slightly and to resume its norfinal position.

' Referring to Figs. 1 and 2,, B B designate guide-fingers which are made of any suitable material, preferably of flexible metal, and each is shown as turned into a coil B, through which the tension-wire passes. One end of each finger is bent at an angle, as at b, and is adapted to engage over the, outer edge of an apron 6', supported upon the carriage of the type-writer. Y designates a platen which is journaled in the ends .of the carriage 'upon suitable spindles, and Y designate rollerswhich are mounted adjacent to said platen,

and Y 'designates an apron or guard which is concaved and mounted in front of the platenroller and immediately below .a roller '1, which latter is positioned underneath the gage Z, as described. The forwardly-extending arm B. of said finger is curved to conform to the contour of the platen-roller, and'itsend is positioned over the gage and preferably is slightly upwardly bent at its end. By reason of the peculiar shape of the finger which extends over the platen-roller a paper which wi's fed about and in contact with the roller is caused to dip underneath the tension-wire as the paper is fed by the rotarv movement of said platenroller.

In Fig. 3 of the drawings a pointer-finger Q is provided, which is fastened at one end .toa fixed part of the machine, and a curved portion Q of the fixed finger extends over the platen-roller and is provided to guide a tion of my tension-fingers, in which the fingers B are formed of flexible pieces of metal,

either ilat springs or wires, which-are bent at B to form coils and movably mounted upon the tension-wire A, while the opposite ends of said fingers are bent, as shown clearly in the cross-sectional View, so that a portion of the flexible finger will form a guide over the the platen-roller, and its extreme end sent down over the gage and underneath a projection S upon the apron Y By the provision of this modified form a slight contact is had both with the front part of the carriage and the tension-bar A. By the provision of the coil-spring at one end of said finger its oppositeend is held yieldingly against the gage and portion of the apron Y Referring to Fig. 5 of the drawings, 1 have shown a still dificrent modification of my ten sion apparatus, in. which the tension wire A is placed across the vertical front of the carrings, as shown in thesectionalview. In,

this case the guide-fingers, which are preferably made ofsheet spring metal, are bent into a V shape, as at A with one arm longer than the other, the short arm engaging the projectioiifiiupon the curved face of the carriage in the rear, while the long arm is restrained by the tens1onwire A and passes upward and curves over the graduated bar or gage and curving over the platen is adapted toguide apaper in the same manner as disclosed by the figures of the drawings which have been described. By this modification the guide-=fingers may he slid laterally adjacent to the-carriage. I

In Fig. 6 I have shown two tensi'onwfires A and A and A is a finger having an eye at one end mounted upon the tension-wires and is provided with 2. lug b, which ser es two purposes, one for the reception of the second tension-wire A", which may "pass through a recess 01'' an aperture in said lug and serves to cooperate with the tension-wire A in holding one end of the finger rigid, and" the other purpose of the lug is to provide means for moving the finger longitudinally upon the tension-wires. By this modification the free end of the linger is positioned over the graduate bar or gage Z.

in Figs. 7 Find 8 I have shown the finger B as pivotally mounted upon the tension-wire about the platen.

The operation of my improved tension deyice is simple and Will be readily understood, as the object of the device is to provide either flexible or weighted fingers for the purpose of guiding. the paper and holding the same.

so that practically the. entire printed matter may be visible to the operator, and thereby reducing to aminimum the number of parts to accomplish this purpose.

-am awarethat it is common in the art to construct paper-controllers which have been placed upon. the carriage of a type-writer; but by reason oftheir rigidity and mountings the visibility of thewritten page is seriously interfered with. By the provisionof my invention 1 am able to get equal if not greater rigidity than with. the mechanism commonly employed and practically eliminate parts which have atcndency to-obscure the matter which is to be written. The guidefinger is held in contact with the'tensiori-wire and may be moved back and forth, as tnay'be desired, to accommodate the same to difier ent widths of paper. I

While I have shown a particular construction of apparatus embodying thefeatures of my tension mechanism, it will be understood that} may vary the same, if-desired, as to details of construction without-in any way departing from thespirit of the invention.

Having thus described my invention, what Iclaim as new, anddesire to secure by Letters Patent,'is

mounted upon the carriage, flexible washers on said wire and nnts'upon the latter.adapted to hold the washers against the ends of the carriage, guide-fingers adjustably mounted upon said tension-wire, and means for holding said finger adjacent to the platen-rolls as Set forth. I I

A paper-controller for "type-writers comprising in combination with the carriage andplaten-roller mounted thereon, a fixed tension-wire supported by the carriage, flexible washers on said wire and nuts upon the latter adapted to hold the washers against the ends of the carriage, an adjustable flexible finger movably mounted upon said tension-wire and I having a flexible end extending 'overthe I l.

In testimony whereof I hereunto afiix my signature in presence of two witnesses.
