TYIWRITING MACHINE l Application filed June 25,

My invention relates to paper lfeed and controlling devices for typewriting and like machines.l Y

. One ofthe main objects of my invention, generally stated, is to provide improved and highly efficient devices of the character specifiedwhich are simple in construction, easy to assemble, and inexpensive to manufacture.

A further object of my invention is to provide means for directing the leadingend of a work sheet beneath feed rollers located. beyond the printing line, without the necessity of adjusting the paper fingers to coact with the work sheet, and without the necessity of throwing such feed rollers ofi1 and introducing the leading end of the work sheet beneath them andagain `restoring the feed rollers to effective position.

To the aboveand other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of Idevices set forth in the following specification and particu- Y-larly pointed out-in the appended claims.

In-the accompanying drawings, wherein like reference characters indicate correspond- -ing parts in the different-views:

I have shown my invention embodied inthe present instance, in the carriage Aof a No.6 Remington-Noiseless machine vin which the invention may be readily included without modifying, or `materially modifying, kother structural features of said machine.- vIt should be understood, however, that ythe invention is not restricted to use inrsuchvmaf chine, but is applicable Vto and mayy ,be employed in typewriting or like machines :generally.

v In said Remington-Noiseless vmachine the carriage comprises a traverse bar 1 to which y 1 u .are connected end plates 2 rprovided with, detail, transverse bearings to support a cylindrical platen v3. The traverse bar 1 is supported by roller bearings in the usual manner to travel Vfrom side to side of the machine.y Y l A paper apron 4, main feed rollers 5 `and 6, and supporting rod 7 are 1mounted inthe manner indicated in my application Sr. No. `180,202 filed April l, 1927, andonlyso much of the details of such construction'are shown inthe drawings of this case pas are necessary to-arrive atan understanding of the-present invention.V In fthe present Ainstance the supporting rod 7 which is arrangednabove or beyond the printing ylinehas one or more flattened sides, being preferably angular in cross section. At its ends the rod' passes through corresponding openings in depending ears 8 (see Fig. 6) on upstanding supporting arms 9 to which the rod is secured by screws 10. Each supporting arm is formed with an upstanding finger piece 11 andv is pivoted at its lower end, as indicated at 12, to the lower end of a de ending link 13. The upper end of each lin 13 vis pivoted at 14 to an vend plate 2. Each arm 9 has a rearward extension 15 to which one end of a coiled contractile spring 16 is attached, the other end of each spring being connected to an arm or plate 17 adjustably Yheld in place on the carriage by a binding screw 18. The force of the springs 16 is exerted through the supporting arms against the rod 7 to hold the paper fingers, feed rollers and deflector carried thereby in normal effective position as shown in Figs. 1 and 5, and with an equally applied pressure at opposite ends of the rod, as will hereinafter appear.

Various paper feed or controlling devices are carried by and adjustable along the supporting rod 7 as will now be described.

'A pair of paper ngers 19, preferably made 0f sheet metal and each provided with upstanding ears 20, are apertured at 21. The walls of each aperture are shaped to correspond to the cross section of the rod 7 which extends through said apertures and supports the paper fingers against turning movement thereon, although each finger is free to be independently adjusted along the rod. Each paper finger is curved to conform substantiallyv tothe surface of the platen; is interposed between the supporting rod and the platen ,andl extends down from the rod located above or beyond the printing line. Each finger crosses the printing line and overlaps the forward edge 4a of the paper apron below the printing line. In this manner work sheet without readjustment of the latter, will have its leading end guided and directed by said 'fingers as it advances from the paper apron and until it passes beneath and beyond the supporting rod 7 and the parts carried there- 50 b In the present'instance I have provided simple and effective detent devices associated with each paper finger and by which it is held against accidental displacement from the position to which it may be individually adjusted along the rod'7. Such detent devices comprisel a metal sleevel22 that fits on and surrounds the rod' 7. Punched inwardly from Vthis sleeve is a spring detent finger 23 that extends longitudinally of the sleeve 22 and the rod 7. This finger at one end 24 is formed v of the'rod 7. This sleeve 22 is of a length by which the associated paper finger may be l adjusted along the rod 7. The surface of the sleeve 25 may be knurled on its surface as indicated at 26, to provide a more effective finger piece for the purpose described.

Intermediate the paper fingers 19 and separate and distinct therefrom is a pair of paper feed rollers 27 mounted on and coaxially of the supporting rod 7 Each of these feed rollers is preferably constructed and mounted as follows z-The outer rubber sheath 28 is fixed on tubular metalsleeve, shell or core 29. This core surrounds and turns freely on a cylindrical supporting sleeve 30, shown detached in Fig. 4. One end of the sleeve 30 is provided with a ange 31 which overlaps one end of the sleeve 29 and prevents relative axial movement between the twoin one direction. After the two sleeves 29 and 30 are assembled a second flange 32 is formed at the opposite end of the sleeve 30 to voverlap the end of and coact with the sleeve 29, thus preventing any relative axial movement between the two sleeves. The sleeve 30 has a tongue or finger 33 punched inwardly therefrom which in form, purpose and'effect corresponds to the iingers 23 hereinbefore described. The free end portion of the finger 33 bearing on a flat side of the rod 7 acts as a spring detent to hold the companion feed roller in the position to which it is adjusted along the rod and also holds the sleeve 30 against turning movement while the feed roller supported on said sleeve is free to turn thereon.

It will be understood that a work sheet a fed forward under the control of the paper fingers will be directed beneath the feed rollers 27 and the supporting rod 7 without necessitating a forward shifting of the rod with the parts carried thereby to introduce the leading end portion of the work sheet between lsuch parts and the platen, as is often'required in other structures.

When a work sheet or card is employed," such as is indicated at b, that is of a width less than the distance between the paper fingers, it has been customary heretofore to adjust the paper fingers towards each otherH until they overlap the side edge portions of such work sheet and then proceed with the writing. After completing the writing the operator may then desire to again employ a wider worksheet such as This would re quire a readjustment of the paper` fingers VBy :my present invention I avoidthis repeated back and forth adjustment when the occasional writing of a comparatively narrow work `sheet orl card is required during thewriting of wider sheets. The devices of the present invention readily lend themselves to thisde- `sired end, inasmuch as the feed rollers 27 may be adjusted independently of the paper fingers. This enables the paper feed rollers to belocated at any desired points along the supporting rod intermediate the paper fingers and to properly coact with a work sheet or card however narrow it may be, and even though the paper fingers do not coact therewith' but remain in the positions to which they are adjusted to coact with the wider work sheets. While the feed rollers 27 will thus coact with the narrow work sheets, they also, without readjustment, will coact with the wider work-sheets that pass beneath the paper fingers. In order that a narrow work sheet or card b may have its leading` end fed beneath the feed rollers 27 and rod 7 while they remain in normal position, I have provided a special defiector which will now be described.

This deflector is preferably made of sheet metal bent at one end to form a sleeve 34 which is angular in cross section. This sleeve f receives the correspondingly shaped supporting rod 7 and is adjustable along the latter although it is fixed against turning movement on the rod. A spring tongue or finger 35 is punched in from the sleeve and bears at its free end portion with a spring pressure against a fiat side of the supporting rod. The construction, purpose and effect of the finger 35 are the same as the fingers 23 and 33, hereinbefore described. That is to say, the finger 35 acts as a spring detent which coacts with supporting rod placement from the position to which they are adjusted along said rod.

Formed as a continuation of one of the sides of the sleeve 34 is a depending platelike eXtension 36 that projects from the lower side of the rod forward and downward in such position that the leading end of a may coact therewith and be deflected thereby into the bight between the feed rollers 27 and the platen. Being thus engaged between said feed rollers and the platen the sheet will be fed forward under the feed rollers andthe supporting rod 7 without necessitating a forward displacement of the rod 7 and the parts carried thereby and a placing of the sheet beneath the same, and without necessi- 7 to hold the sleeve 34 and the parts carried thereby against accidental disstruction, and Yparts thereof may 'be em-VL "b Lett r I t t, work sheet uncontrolled by the paper fingers Y y e s a en 1S Apaper controllingidevice in adjusted/position.`

tating anadjustment of the paper fingers to coact with such narrow sheet. In practice 4I Aprefer to locate the defiector just described 'intermediate the feed rollers 27 and preferably about midway in the length of the rod 7 where it will vnot interfere with the ready adjustment of the feed rollers `27 and paper fingers 19. However, the deflector, as well as said feed rollers and paper fingers, is individually adjustable so that the parts may '75 be adjusted to assume various relations. For example, the parts may be adjusted so that a comparatively narrow card may be controlled and written from an off-centered position corresponding to that near which one side of either a centered or off-centered comparatively wide work sheet is controlled.

It'will be understood that the construction is such that the parts may be readily assembled on the supporting rod 7 when the "35 latterjis detached from its supporting arms :9, by merely slipping the vsleeves 22, 30 and 34 lwith the parts carried thereby over an end of the rod inthe order shown and thenv *attaching the rod to the arms 9 `by the screws 90 From the foregoing it will be understood that I'have provided simple, inexpensive and effective means 'for feeding and controlling lwork-sheets of different fwidths and with/the aid of which repeated adjustments, re-arrangements, or releasing ofthe parts with consequent Vdelays and eXtra work incident `thereto are avoided.

As pointed out in my Vhereinbefore men-l tioned previously filed application the mounting ofthe supporting rod 7 on thelinlrs ror arms 9 and 13, and applyingthe force of the springs 16 thereto in the manner shown enables the yrod to receive a limited canting Ymovement out of parallelism `with'the yaxis of the platen as well as to remain in parallelism therewith. -This results in applying the paper feed devices near the opposite ends ofVM the yrod against the platen or the paper therei m0 on with substantially equal pressure and effecting a straight feed of the paper under varying conditions.

f i Various changes may-be made in they conployed, without others, without departing from my invention as it is defined in the vaccompanying claims. f
