FRANZ X. \VAGNER, OF NEW YORK, N. Y., ASSIGNOR TO THE WAGNER TYPEVVRITER COMPANY, OF SAME PLACE.

PAPER-CARRIAGE AND INDEX MECHANISM FOR TYPE-WRITERS.

SPECIFICATION forming part Of Letters Patent NO. 624,135, dated May 2, 1899.

Application filed December 12 1898. Serial No. 698,967. (No model.)

To all whom it may concern.-

Be it known that I, FRANZ X. WAGNER, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Paper-Carriages and Index Mechanisms for Type-Vriters, of which the following is a specification.

My invention relates to paper-feed mechanism and to index mechanism for typewriters; and said invention consists in the novel arrangement and combination of parts hereinafter described and claimed.

Type-writers have heretofore been devised which employed separatelymounted marginal feed-rollers that were adapted to bear upon the paper near each side edge of the paper and a central feed-roll near the front of the platen and main feed-rollers that were adapted to bear upon the paper throughout a considerable extent of the length of the platen. In such constructions, however, these feed-rollers or sets of feed-rollers have been separately moved and maintained out of action when it was desired to straighten the paper on the platen. It will be understood that the several movements required to move these feed-rollers out of and into contact with the platen occasioned considerable delay every time it was found desirable to adjust the paper on the platen.

The object of my invention is to overcome the difficulties heretofore encountered in type-writing machines and to provide a'simple and efficient mechanism for simultaneously throwing the feed-rolls which cooperate with the paper-platen out of operation by a single operation of a hand-actuated lever.

A further feature of my invention consists in moving an indicator to and from the printing-pointby a movement of the lever which causes the feed-rollers to be moved into and out of contact with the paper-platen.

In the accompanying drawings, wherein like characters indicate corresponding parts in all the views, Figure 1 is a plan view of sufficient number of parts of a type-writing machine to illustrate my invention. Fig. 2 is a front view of the same with parts removed for the purpose of clearerillustration, the paper being shown in place in the papercarriage. Fig. 3 is a bottom view of the platen-carriage and the parts carried thereby. Fig. 4 is a transverse sectional view of some of the parts illustrated in Fig. 1, the

View being taken on the line 4 4 of Fig. 1. N

Fig. 5 is a detail perspective view of the cen tral-feed-roll-displacing cam and its carrier.

I have illustrated my invention in the pres ent case as adapted to the well-known Underwood type-writer. It will be understood, however, that my invention may be employed in any form of machine wherein an application of said invention is found feasible and that changes in detail may be made to adapt my improvements to other types of machines than that illustrated.

In the drawings, 1 indicates the main frame of an ordinary Underwood machine, in which a paper-carriage 2 is adapted to reciprocate from end to end for the production of lines of writing. The paper-carriage 2 is provided wit-h an auxiliary frame 3, which constitutes the platen-frame or carriage proper. In this platen-frame 3 is carried the platen 4, which may be rotated in any suitable manner to produce the spacing between the lines. Suitable mechanism (not shown) is provided for moving the platen-frame in a vertical direction in the carriage to bring theprinting-line into alinement with either the upper or lower case characters a h, respectively, on the typeb'ars. (See Fig. 4.) The platen-frame or carriage 3 isprovided with a paper-shield 5,which guides the paper to the platen. This shield extends from the rear portion of the platen, as indicated in Fig. 4, to a point below the central front portion of the platen, as indicated at 6, and apertures 7 are provided in the shield, through which apertures extend the main feed-rollers S. The feed-rollers 8 are shown as three in number and are loosely mounted upon a shaft 9, which is carried by arms 10. These arms 10 are provided with sleeve-like portions 12, that carry ratchetfaces 13, which engage in corresponding ratchet teeth upon sleeves 14, which are loosely carried upon a rod 15, and the sleeves 14 are preferably provided with openings 16. Each of the sleeves 14 is connected to a coiled spring 17, which is in turn connected to a sleeve 18, fixed to the shaft 15. It will thus be seen that a rotation of the sleeves 14 will increase or decrease the tension of the springs upon the arms 10 and feed-rollers 8 in accordance with the direction in which said sleeves 14 are turned. It will of course be understood that the engaging teeth between the sleeves 12 and 14 will maintain the parts in the relative positions to which they are adjusted. The shaft 9, hereinbefore referred to, is extended beyond the arms 10, as indicated in Fig. 3, and these extensions are provided with cams 19, which cooperate with arms 20 near each end of the platen, that are adapted to slide in the longitudinal direction of the shaft 9, as will be hereinafter explained. These arms 20 are fixed upon a longitudinally-movable rod 21, that slides in bearings 21 of the platen-frame, and said arms are extended upon the opposite side of said rod to form extensions 22. These arms or extensions 22 are each provided with a cam-finger 23,'which cooperates with an abutment or extension 24, connected with the support 25 of each of the marginal rollers 26. (See Figs. Band 4.) These marginal rollers 26 are adapted to bear upon the paper near each end of the platen and are, as before stated, carried by the supports 25, which in the present instance consist of spring-arms bent, as indicated at 27, Fig. 4, and secured, as indicated at 28, to a portion of the platen-frame 3. It will thus be seen that the marginal rollers 26 are independently mounted near each end of the platen and are adapted normally to be maintained in contact with the platen by the spring-pressure of the supports 25, in which they are mounted, and that a movement of the rod 21 in one direction will cause the cam-fingers 23 to move the marginal rollers 26 out of contact with the platen or the paper on the platen, whereas a movement of said rod in the opposite direction will bring the lowest portion of the cam-fingers 23 under the abutments 24, thereby allowing the rollers to simultaneously move into contact with the platen or with the paper on the platen. In order to bring about this longitudinal movement of the rod 21, I have provided a hand operated lever 29, which is pivoted, as indicated at 30, upon the platen-frame and is provided at its lower end with a slot 31, in which a pin 32 upon the rod 21 engages.

Upon reference to Fig. 2 of the drawings it will be observed that an independentlymounted feed-roller 33 is pivoted in a springpressed frame 34, secured to an extension 35, (see Fig. 4,) extending from the rod 15. This spring-pressed feed-roller 33 is adapted to be forced through an aperture 36 in the shield 5 and to be normally maintained in contact with the paper-platen by the pressure of the spring-pressed frame of said feed-roller. This spring-pressed frame or support 34 is provided with a pin 37, (see Fig. 4,) with which cooperates a cam 38, (shown in detail in Fig. 5,) carried by the longitudinally-movable rod 21. The cam 38 is so located with relation to the pin on the spring-pressed support 34 that the roller 33 will be moved out of contact with the platen when the longitudinally-movable rod 21 is moved in a direction which will cause the marginal rollers 26 and the main feed-rollers 8 to be forced out of contact with the platen, and the parts will be maintained in such position untilthe rod 21 is moved in an opposite direction by the hand-operated lever 29. The rod 21 is likewise provided with studs 39, each of which carries a pin 40, that passes through a cam-groove 41 in a m ovable indicator-bar or scale 42. This scale 42 is connected by a link 43 to one end of the platen-frame, as indicated at 44. This scale is mounted so that the upper edge thereof may be brought directly beneath the line of writing by the hand-operated lever 29, as indicated in Fig. 2 of the drawings, whether the platen be in the lower or elevated position. This is due to the fact that the scale and its cooperating parts are carried by and moved bodily with the platen-frame. The indices 45 upon said scale are so arranged that no matter at what point the carriage be with relation to the printing-point an index 45 will always be brought to the printing-point when the scale is elevated by the hand-operated lever 2.). The indices are equably arranged, so that any one index brought to the printing-point will indicate the relative positions of each character throughout the line, as the spacing on the scale corresponds to the distance between the characters written. It will thus be understood that the scale not only affords an indication of the printing-point, but that it likewise indicates the line on which the characters will be written. However, where an indication of the line alone is desired the bar 42 may be made without indices thereon. \Vhen the scale is moved by the hand-operated lever 29 to the dotted-line position represented in Fig. 2 of the drawings, it is conveyed to a position where it does not interfere with the writing, as will be seen by reference to Fig. 4 of the drawings. In this view a typebar 46 is shown in the printing position with a ribbon 47 interposed between the characters on the type-bar and the paper on the platen. This ribbon 47 is carried by suitable mechanism-such, for instance, as a guide 48-which in the present instance is automatically operated by suitable mechanism (not shown) to convey the ribbon into the path of the characters on the type-bar j ust before such character reaches the platen and to automatically move the ribbon out of the line of writing after each character is written.

It will be observed that by my invention I am enabled to move all of the feed-rollers into and out of contact with the platen and to simultaneously move the scale or indicator to the position where it is available to indicate the printing-point and the position of a line of writing and that the only movement required to bring about this movement of the scale and the feed-rolls is that given to the hand-operated lever 20, whereas in the type of machine wherein such rollers were heretofore employed it was necessary to make several movements in order to carry the marginal, central, and main feed1'ollers out of contact with the paper on the platen.

The indicator or scale is seldom required except when the paper is to be adjusted upon the platen, and when this is necessary it is desirable to force all of the feed-rollers out of contact with the paper on the platen, so that the paper will be entirely free from the pressure of the feed-rollers and may be readily moved to any position desired. In accordance with my invention the rollers are moved out of contact with the paper, and the scale is automatically moved into the indicating position and is automatically moved out of such position when the rollers are again allowed to bear upon the paper.
