SPECIFICATION forming part of Letters Patent No. 784,376, dated March '7, 1905. Original application filed February 6, 1902, Serial Nd. 92,839. Divided and this application filed June 3, 1902. Serial No. 110,041.

T 0 all whom, it Hz/my concern:

Be it known that we, WALTER J. BARRON, a resident of the borough of Brooklyn, county of Kings, city of New York, and State of New York, and HENRY W. MERRITT, a resident of Springfield, county of Hampden, and State of Massachusetts, citizens of the United States, have invented certain new and useful Improvements in Type-lvriting Machines, of which the following is a specification.

This application is a division of our application, Serial No. 92,839, filed February 6, 1902.

Our invention relates to type-writing machines, and more particularly to paper feeding and guiding devices therefor; and the object of the invention is to provide simple and eflicient devices of the character described.

, To these and other ends, which will hereinafter appear, the invention consists in the construction, arrangements, and combinations of parts hereinafter described, and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters designate corresponding parts in the various views, Figure 1 is a detail front view of the platen, platen-frame, and certain of the cooperating paper feeding and guiding devices constructed in accordance with our invention. Fig. 2 is a fragmentary transverse sectional view through the carriage. Fig. 3 is is a detail side view of one of the paper-feeding devices. Fig. 4 is a longitudinal sectional view of the same, showing the parts in different positions. Fig. 5 is a detail front elevation of the carriage and the platen-frame seated therein, with the bar 5 broken away.

o have shown our invention applied to the carriage of a Densmore type-writing machine; but obviously it or any of the separate features thereof may be applied to other characters of type-writing machines.

The carriage 1 is mounted to travel with the sleeve 2 and truck 3 on a traverse-rod 4c, the forward rail or cross-bar 5 of the carriage being grooved at 6 on its under face for cooperation with the bearing-rollers 7, carried by the shiftrail 8, and by means of which the carriage, together with its platen-frame 9 and platen 10, are supported at the front of the machine and shifted transversely of the length of the platen for upper and lower case writing. The platen frame comprises end bars 11, united by cross-bars 12 and 13, the latter at the rear and the former at the front of the frame. The carriage 1 has upright arms 14, the space between which constitutes slots in which the shaft 15 of the platen is seated and guided when the platen is turned to expose the writing. The platen-frame is provided with an outwardly-extending stud or roller 16 on each end bar 11, that bears on a cam track or guide 17 on each end of the carriage, so as to raise the platen-frame and platen as it is turned by the linger-piece 18, which is formed integral with the left-hand end bar 11 of the platen-frame.

Upon the front bar 12 of the platen-frame are mounted certain paper feeding and guiding devices, one on each end, but only one of which is shown, that being deemed suliicient to illustrate this feature of our invention. This paper feeding and guiding device comprises aframe 19, having down wardly-extending apertured cars 20 to receive the supporting-bar 12 and to permit the frame to slide longitudinally thereon. Extending from this frame are two right-angle rearwardly-projecting cars 21., that receive between them cars 22 on a curved paper guiding and feed finger 23 which may, if desired, be provided with a feed-roller 24 and a portion of it may conform substantially to the contour of the platen. The cars 22 are pivoted to the cars 21 at 25, and a cam-linger 26 is pivoted at 27 between the ears 21 and is provided with a finger-piece 28, by means of which the paper-linger and its feed-roller 24: may be held against the platen or the paper thereon by pressure, the finger 23 being made of springy or resilient sheet metal.

\Vhen the cam 26 is in the position shown in Fig. 3, the finger 23 and feed-roller will press against the paper. When, however. the finger-piece 28 is moved to the position represented in Fig. 4, the guiding-finger will be relieved of the pressure of the cam 26 and will drop away from the platen and will be ineffective to press against the paper.

Referring to Fig. 4, it will be seen that the horizontal portion of the frame 19 is provided with a stud 29, which receives a small spiral spring 30, that bears upon the supporting-bar 12, and the friction of said spring maintains the frame in any position to which it is moved along the bar.

From an examination of Figs. 1 and 5 it will be seen that the frame 19is provided with an index mark 31, which is adapted to register with certain numbers on the front side of the supporting-bar 12. These numbers or indices on the bar correspond to aplurality of letterspace distances and to certain of said indices on the carriage scale a, carried by a bar a, that extends from side to side of the carriage 1. Thus, for instance, the distance between the numerals 5 ant 10 on this bar corresponds to five letter-space distances and to the distance between the point 5 and 10 on the carriage-scale.

It will be observed that the free end of the paper-guiding finger extends rearwardly or past the under side of the platen on which the impressions are made, and care should be taken in adjusting this finger that when the carriage is at the right hand for the beginning of a line the said finger shall not lie to the right of the printing-point or coincide therewith, for if it should it will be seen that the types would strike the said finger either at the beginning of the printing operation or subsequently as soon as the finger reached the printingpoint in the travel of the carriage toward the left, and such striking would of course be injurious to the types, besides leaving an unprinted space on the paper. To avoid this objection and to facilitate the adjustment of the finger while the platen-frame is down in the working position is the purpose of the set of numbers 5, 10, 15, and 20 on the bar 12 and of the index 31 on the paper-finger frame or support. In other words, it is desirable to set the paperfinger relatively to the position of the righthand margin-stop of the machine. Thus, for instance, if the right-hand margin-stop be positioned at 10 (in order to start the writing at the left-hand side of the paper at 10) the paper-finger support should be moved along the bar 12 until its indicatingpoint 31 is brought into register with the numeral 10 on the bar, when the parts will bear such relation one to another that the paper-finger will be on the left-hand side of the printing-point when the paper-carriage is pulled to the right and positioned at 10 on the carriage-scale a. It will be understood, of course, that if the carriage is to be positioned by the marginstop at 15 or at 20 the paper-finger is set either at 15 or 20 of the scale on the front bar 12.

WVhile we have shown the scale on the bar 12 as formed in periods of five and which we have found is sufficient in practice, there may, however, be provided graduations between the numbers 5 and 10 and 10 and 15 and 15 and 20, so as to enable finer adjustments of the paper-finger to be made with reference to such scale.

Upon reference to Fig. 2 of the drawings it will be seen that a paper-table 32 is provided near its lower edge with hooks 33, that partly surround the rear cross-bar 13 of the platen-frame. This paper-table is provided with a sheet-metal strip 34, which is riveted to the table only at its lower end by fiat or flush headed rivets. This strip 34 bears and rides against an arm 35, connected to the carriage 1, during the turning up and down movements of the platen-frame, the papertable turning about its hinged rod 13 in said movements and being provided with the usual spring (not shown) for keeping the paper-table normally in contact with its back-stop and for restoring the paper-table to the normal position when the platen-frame is turned down to the working position.

The paper-table 32 is provided with an adjustable paper-guide 36, which constitutes an abutment for the left-hand edge of the paper. This paper-guide 36 is preferably formed integral with the bar 36*, which extends lengthwise of the table and is freely movable in guideways 37 attached to the table, and a,

suitable stop or projection 38 is provided on the right-hand end of this bar to prevent its withdrawal from the guideways 37. The bar itself is placed on the back of the paper-table,

, so as not to interfere with the paper; but the guide 36, carried thereby, extends forwardly and projects over the top edge of and at an angle to the plane of the paper-table, as indicated in Fig. 2. The bar 36 is provided on its front face with a scale or with numbers corresponding to the scale or numbers on the front bar 12 of the platen-frame, and said scale or numbers may be read through a sight hole or opening 39, formed in the paper-table and with which the numbers are adapted to be brought into register. The relation of the numbers on the bar 36 with their sight-opening 39 and their relation to the numbers on the supporting-bar 12 are such that the paper-finger 23 will be brought into substantial transverse alinement with the guide 36 when a given number on the bar 36 is brought to the sight-hole and the paper-finger frame 19 is adjusted on the bar 12 to a like number that is to say, if the paper-guide 36 is adjusted relatively to the paper-table so that the number 15 on the bar shows at the sighthole and the paper-finger-supporting frame 19 be adjusted on the bar 12 so that the index-mark 31 registers with the number 15 on the bar 12 then the paper-finger 23 will be in proper position to receive the paper and guide it around the platen if the paper he started in around the platen with its left-hand edge against the guide In practice the relationship of the scales on the bars 12 and 36 and the sight-hole 39 and index 31 are such that when the former have been adjusted to a given number on both scales the paper-finger 23 will stand slightly to the right of a vertical plane passing transversely through the platen and the guide-finger 36, so as to insure the proper engagement of the paper-finger and its roller 21L with the left-hand marginal portion of the paper. By the use of the guide 36 successive sheets in a given piece of work may be so positioned on the platen that all of such sheets will have exactly the same width of margin at the left-hand sides of the printed sheets. The usual feedrollers (indicated in dotted lines at 40 in Fig. 2 of the drawings) may be provided to cooperate with the platen in feeding the paper.

From the foregoing description it will be understood that simple and efficient means are provided which can be readily adjusted to cooperate with sheets of various widths to accurately and efiieiently feed and guide the sheets.
