My invention is illustrated as applied to a platen carrier like that employed on the Smith Premier typewriting machine, but the nature of my improvements is such that they may be readily adapted to other forms of writing machines.

In carrying out my. invention in the present instance I arrange a pair of parallel links on the rear rod oi? the platen carrier, said links carrying-a feed roller which may be termed a secondary or supplementary teed roller in contradistinction from the usual main feed rollers and alsp from the usual n'iargin feed rollers of the machine. This secoiidary feed roller extends lengthwise of the platen and is arranged above or in advance of the main feed-roller and between the platen and the usual paper table. Springs tend constantly ,to press this supplementary feed roller into engagement with the platen or the paper. thereon. The paper table is inclined u wardly away from the the introductory side thereof and forms with theplaten a sort of pocket-like opening comparatively wide at the top or sheet and the substitution of another the record sheet remains in the control of the platen and the secondary feed roller.

The special advantages of my invention will be explained at length later on.

In the drawings 1 designates the top plate on which are supported oppositely grooved track-ways 2 andtl which receive anti-friction balls -t, the latter also coiiperatiug with the grooved front and rear bars 5 and (3 respectively of a carriage truck, the latter also comprising end or side bars 7 only one of which is shown. A rotary platen 8 is secured to a platen axle 9 which is supported on the side bars 7 of the carriage truck. The platen axle is journaled on lhc end plates 10 of a platen frame or carrier the.

latter also comprising front and rear bars numbered respectively 11 and 12. Studs 13 project laterally from the side plates 10 of the platen frame and are engaged by hooked links 14.- pivoted at 15 to the side bars 7 of the truck. The truck and the platen frame or carrier constitute a platen carria 'e. It will be understood that the platen is adapted trolled in such movements by the usual line spacing devices (not shown), or by the finger wheels 16 fixed on the ends of the axle 9. It will further be understood that the platen "and platen frame are adapted to be rocked on the carriage truck to expose the writing, the rockin movements being conveniently controlled y a finger piece l7 fixed to the front bar 11 of the platen carrier. Links 18 are pivoted to and depend from the rear bar or rod 12 of the platen carrier, said links calrrying a rod or shaft 19 in which is mounted a paper feed roller 20 hereinafter termed the main feed roller. This paper feed roller extends lengthwise of the platen and is shown in the present instance as a single roller though obviously it may be divided to provide a plurality of separate rollers. The roller 20 is pressed into engagement with the platen or with the paper thereon by leaf sprin s 21 which are secured by nuts 22 to threa ed pins 23 projecting rearwardly from standardslQl rising from and fixed to the rear bar 12 at each end portion thereof. The lower or free ends of the springs 21 cotiperate with sleeves 25 arranged on the rod 19, one near each end between an end of the feed roll 20 and the neighboring link 18. The paper table 26 is suitably secured to the standards 24 and is inclined upwardly at the rear or introductory side of the platen and above the main feed roller 20. A rod or shaft 27 is carried oy the linksu18 below the rod 19 which supports the main feed roller, said rod 27 being of smaller diameter than the rod 19 and serving as, a pivotal sup rt for a. (paper plate 28, the latter exten ing forwar ly at the under side of the platen and its free end portion being springressed toward the platen by the rear en portions of paper guiding fingers 29, the latter being suitably secured to supporting arms 30 rising from the front frame bar 11 and slidablymounted not differ essentially from those found on the No. 4 Smith Premier machine and it is not deemed necessary to describe them at greater length.

A hand-operated releasing lever 31 is suitably secured to the left end of the rod or shaft 19 in a fixed relation with said rod or shaft, said lever being provided with a tail 32. When the hand lever '31 is swung forward its tail fulcrums in the usual way on the platen frame near the rear left-hand corner thereof, the movement of the lever being effective to release the mairnfeed roller 20 or move it away from the platen to inoperative position as shown in Fig. 4. From an inspection of this figure it, will be noted that the releasing operation also serves to release the paper plate 28 and-the paper fingers 29, the pivotal movement of the paper plate on the rod 27 being limited in one di rection so ihat the plate is effective tomove oil the paper fingers.

I prefer also to employ means for locking the main feed roller, the aper plate and the paper fingers in release position and any convenient means may be made use of for this purpose. That shown in the drawings end. Engaging this slot is a headed screw 38 which projects inwardly from the inner face of the left-hand side plate 10 of the platen frame.

The normal relation between the screw 38 and the latch 33 is shown in Fig. 2 where it will be noted the screw 38 is engaged with the forward end of the slot- 36. When the latch 33 is employed and it is desired to release the paper feeding and controlling devices and lock them in released position, this may be accomplished by pressing forward and dowliward against the finer i ece 35 of the latch, causing therele'asmg. ever 31 to swing forward to release the paper feeding and controlling devices and causing the latch 33 to move forward bodily and to turn slightly on its pivotv 34. The result is that the lower edge of the slot 36 bears against the shank of the screw 88 as the latch mo'ves forward, and when the extension 37 of the slot 36 reaches the screw 38 the latch receives a slight upward pivotal movement so that the extension 37 engages the pin, locking the parts in the, positionshown in Fig. 4.

Une 033 these ige-ways is between the secondary feed lien and the platen and the work sheet inoducod into this passage-way is fed iniby the cooperation between said feed roller and the platen. The other passageway is between the secondary feed roller and the wiper guide or table 26 and the Work sheets introduced into this passage-way are passed downward over the paper table without thc'r being ndectsd by the secondary. teed roller. The inclined paper table 26 fOll'uS with. the platen a sort of V-shabped opening or pocket which widens gradually from the bottom toward the top and in the mouth of whicn the secondary feed roller is located. The bottom of the pocket forms ft comparatively narrow opening toward which the work sheets introduced at opposite sides of the secondary feed roller gradually converge and through which they pass downwardly into the control of the main food roller which in the present instance is located below the paper table. The paper table or plate-like paper guide 26, it will be noted, though bent slightly at its top and. bottom edges away from the platen, lies for the most part in a plane which may be termed the general plane of the paper table or paper nude, and it will be seen that by arranging the secondary and main feed rollers at opposite sides, or substantially at opposite sides of the general plane of the paper table, the secondary feed roller being at the front and the main feed roller for the most part behind this general plane, I am enabled to obtain desirable results. Furthermore, the construction is such that certain of the sheets may pass to one side of the secondary teed roller and between it and the platen so that said roller coach; with thesheet or sheets in question to clamp th in to the platen and effect a feed thereof wh V dchll'EL'l, whereas another sheet or other sheets pass on the opposite side of said roller and are out of thocontrol thercof and may be introduced into or removed from the machine without disturbing said roller or the sheets, or sheets controlled thereby. f

Various chan may be made in the con stroctionsvithout departing from the spirit and "scope-sit my invention.
