FEED MECHANISIVI.

SPECFICATION forming part of Letters Patent No. 769,677, dated September 6, 1904. Original application filed July 24, '1903y Serial No. 166,881. Divided and this application filed December 2l, 1903. Serial Be it ltnown that I, CHARLES Jv. BELLAMY, a citizen of the United States of America, residing at Springlield, in the county of Hampden and Commonwealth ofMassachusetts, have invented new and useful Feed Mechanism, of which the following is a specification, a portion of said mechanism constituting' a divisional part of the subject-mattei' of an application for Letters Patent of the United States filed by me July i4, 1903, and serially numbered 166,881.

My invention relates to improvements in devices adapted to handle paper, preferably from a roll, for use with a hand writing-board or otherwise, as desired; and it consists of certain peculiarly constructed and arranged members, as hereinafter set forth; and the objects of my improvement are, first, to provide means for drawing' paper from the bed of a hand writing-board, for example, after it has been written upon without blotting' or blurring' the writing; second, to provide such drawing means as shall permit of practically au unobstructed view of the written matter adjacent thereto; third, to obviate the need of a blotter when ink is used; fourth, to afford suitable means for backing the paper; fifth, to furnish means for holding' the paper absolutely taut at all times; sixth, to furnish adequate means for placing the paper in position and properly adjusting it; seventh, to provide a suitable tension appliance for a roll of paper and the paper itself as it leaves the roll, and, eighth, to provide practicable and efficient feed meclianism,more especially for hand writing-boards, which possesses the necessary facilities and advantages and is simple in construction and operation, inexpensive, and durable.

I attain these objects by the means illustrated in the accompanying' drawings, in which# Figure 1 is a plan view of a hand writingboard equipped with my feed mechanism; Fig'. Q, a right-hand side view of said board and mechanism, showing' the paper in position ready for operation; and Fig. 3, a longitudinal vertical section through the same, taken lNo model-l on lines :u a' looking' in the direction of the arrow in Fig. l.

Similar reference characters refer to similar parts throughout the several views.

Although a single-strip roll of paper is described as being used in connection with the mechanism shown in the drawings, it is to be understood that when a dupiicate of the written matter is required a double-strip roll may be employed. 1t is obvious, too, that the roll or paper-supply may be suspended at some convenient place remote from the board with which the mechanism is associated instead of being' mounted directly thereon, if desired.

r1`he mechanism comprises generally certain peouliarly-arranged actuating or feed rollers mounted on or in a suitable frame provided with a support or supports for the hand and the pen or pencil of the writer, with other auxiliary or subsidiary parts, including a tension appliance for the paper and roll, all as hereinafter explained.

Vhen the mechanism is employed with a hand writing-board, any suitable form or style of frame may be provided, that in the drawings consisting' of side pieces 1 1, connected by cross-pieces 2 and 3, a handrest a, having side pieces 5, which are supported by the side pieces 1, and a writing-bed 6, located back of the rest between the side pieces 5, a slot '7 being' left between adjacent edg'es of said rest and bed. The front edge of the bedA that is, the edge which forms the rear side of the slot T-is rounded, so as to afford a suitable bearing for the paper in its passage through said slot, and the rear edge of said bed is also rounded in the present instance. A guide-plate S, curved upward at its front terminal, extends between the sides l from a position beneath the large roller 9 forward below the bed 6 to the slot 7, the inside face of the upwardly-eurved part of said plate coinciding' with the front edge of said slot. The object of this plate is to guide the paper to the slot.

Standards 10 10 rise from the sides 1 back of the side pieces 5 to furnish bearings for the shaft 11 of two marginal rollers 12.' The shaft 13 of a roller 14 is journaled below the shaft 11. The large roller 9, ,which may be covered with rubber or other suitable material, has a shaft 15, to the terminals of which the forward ends of springs 16 16 are attached, the rear ends of said springs being attached to pins 17 17, extending laterally from the sides 1, and these springs draw said roller into contact with or toward the

rollers

12 and 14. It will now be seen that the marginal rollers 12 while acting upon the paper as it passes between them and theroller 9 in no case come in contact with any otherportions of the paper than the margins thereof, thus obviating all danger ofl blotting or blurring the matter written upon said paper. Furthermore, said marginal rollers do not obstruct the view of the written matter in its passage over said roller 9. The lower roller 14 serves two purposes, one of which is to tightly hold the strip (or strips) of paper under tension, as it were, so that it (or they)v can be drawn smoothly or evenly over the writing-bed, thus keeping the paper in proper condition to receive writing, and the other is to make it possible to back the paper by reversing the feed, which would otherwise be impracticable if not impossible Without rewinding the paper on its roll by hand at the time the backing takes place. In case it is, however, desired to dispense with a roll of paper this lower roller can be omitted with approximately satisfactory results, a sheet r strip being led up the hand-rest 4, the slot 7 not being required in such case.

Fixed bearings 18 18 are provided in front of the standards 10, into which the terminals of the shaft may be placed by drawing forward the roller 9 against the resiliency of the springs 16 when it is desired to clear the passage between the rollers either for the introduction of the paper or for the adjustment of the same. Such forward position of the roller 9 is indicated by dotted lines in Fig. 2. It will also be readily observed that the tension on the paper can be relieved at either side or both sides by slightly pulling' out the roller 9 without setting its shaft in either one of the bearings 18.

Holders 20 2O are firmly mounted on the tops of the side pieces 1 at the back for the shaft 21 of a paper-supply roll 22. Pins 23 23 may be used in the tops of the supports or holders 2O above the adjacent parts of the shaft 21 to prevent the same from leaving its bearing-recesses. A frictional tension-rod 24 is slidingly supported on stops 25 25, mounted on the side pieces 1 in front of the holders 20. This rod is held in contact with the paper-roll by means of springs 26 26, extending between ears 27 27, rigidly attached to the ends of said rod, and pins 28 28, projecting from arms 20 2Oa on the holders. The springs 26 not only hold the rod 24 against the roll 22, but cause said rod to slide along the stops 25 and remain in contact with said roll, as its size decreases a non-rotary rod than over one which rotates,

provided other conditions are the same.

The paper strip or web 29 passes from the roll 22 over and partly around the rod 24, thence between the

rollers

14 and 9 to the slot 7, the plate 8 serving to direct the paper to said slot, and finally backward over the bed 6 to the

rollers

9 and 12, from between which said web emerges back of the roller 12. That portion of the web which is immediately back of the tension-rod is quite firmly pressed against the balance of the roll, between which and said rod it passes, by the latter, and more resistance is o'ered by the rod when the web is drawn over the same.

In the present instance I use the roller 9 as the primary actuating or feed roller, applying a knob 30 to its left-hand end for convenience in operating the mechanism. By turning the knob 30 so as to revolve the roller 9 in the direction of the arrow in Fig. 2 the upper reach of the strip or web 29 will be actuated backward by reason of the contact of the

rollers

14 and 9 with the lower reach of said web and the contact of the

rollers

9 and 12 with the upper reach of the web, the paper traveling in the direction indicated b y the arrows in Fig. 3. By reversing the movement of the actuating or feed rollers the paper will be backed and caused to pile up between the

rollers

14 and 9 and the tension appliance, from which position it may be either drawn forward again for writing purposes or rewound upon the roll 22. The tension appliance serves to keep the paper-roll from rotating when the IOO IIO

web is not in motion or when backed and assists in rewinding the web on the roll by guiding the paper and preventing' twisting, as well as obviating backlash and performing the other functions already fully described. The hand holding the pen or pencil rests on the part 4, and the writing is done on the bed 6, the upper reach of paper being actuated rearward after one line 0r more has been written to bring a fresh portion of paper into position for more writing. When ink is used, no blotter is required, for thereason that the rollers 12 bear only on the margins of the paper on the side upon which the writing appears.

Although I have shown a complete and thoroughly operative embodiment of my invention, it is clear that various changes of minor importance may be made in the construction and arrangement of some or all of ISO its parts Without departing from the nature of said invention. For example, the handrest might be omitted and the writing-bed lengthened, in which event the hand of the operator would rest upon a desk or other support; but the paper strip would still pass around the front edge of said bed.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

l. Feed mechanism comprising a feedroller, other rollers contacting' only with the end portions of said feed-roller or with the margins of an interposed strip of paper, and means to draw the first-mentioned roller toward and into resiliently frictional Contact with the mar'ginal rollers or with the paper between.

2. In feed mechanism, the combination with a paper-feed roller, of a set of short rollers located at the ends of the feed-roller, and means to tension the feed-roller toward a line conneeting' the peripheries of the short rollers at points situated between the extremes of their lower front quadrants.

3. In feed mechanism, the combination with a suitable support, of a set of paper-feed rollers comprising' a middle roller and another roller of substantially the same length and two rollers located at the ends of said middle roller out of contact with the second-mentioned roller, and means to tension the middle roller toward theother rollers.

4. 1n feed mechanism, the combination with a frame and a series of parallel rollers journaled therein, some of which are marginal only in bearing', of another roller of too great diameter to fill the space between the parallel rollers, said large roller having movable bearings, and resilient means connected with said bearings for tensioning said large roller toward sueh space, the marginal rollers being' located at the ends of the large roller.

5. In feed mechanism, the combination with a frame and a series of parallel rollers journaled therein, of an adjustable roller too large to fill the space between said parallel rollers, means to normally tension the adjustable roller toward such space, and means to set and retain the adjustable roller out of contact with the other rollers.

6. In feed mechanism, the combination with a suitable frame and paper-feeding rollers, of a paper-supply-roll holder, a friction-rod arranged to divert the paper, as drawn from the supply-roll by said feeding-rollers, out of its direct course from the line of contact between the friction'rod and supjlily-roll, stops for said rod against which it is caused to bear by the pull of the paper, resilient `means to draw the rod toward the rollholder, and means to prevent the rod from rotating'.

ln testimony whereof I have signed my name to this specification in the presence of two subscribing' Witnesses.
