CHARLES J. BELLAMY, OF SPRINGFIELD, MASSACHUSETTS.

HAND WRITING-BOARD.

SPECIFICATION forming part of Letters Patent No. 769,678, dated September 6, 1904.

Original application filed December 21, 1903, Serial No 185,984. Divided and this application filed February 25, 1904. Serial No. 195,266. (No model.)

To 1!]! whom it iim l concern:

Be it known that I, CHARLEs J. BELLAHY, a citizen of the United States of America, residing at Springfield, in the county of Hampden 5 and Commonwealth of Massachusetts, have invented a new and useful Hand \VritingBoard, of which the following is a specification, the same being a divisional part of an application for Letters Patent of the United States filed by me December 21, 1903, and serially numbered 185,9Sa.

Hy invention relates to improvements in hand writing-boards or similar devices; and it consists of certain peculiarly constructed and 1 arranged members, as hereinafter set forth and claimed; and the object of my improvement is to provide a simple, inexpensive, durable, convenient, and practicable hand writing-board which is adapted to successfully handle paper 2 0 without blotting or blurring the writing therethe same, taken on lines :r ;r looking in'the direction of the arrow in Fig. 1.

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

Although a singlestrip roll of paper is described as being used in connection with the device shown in the drawings, it is to be understood that when a duplicate of the written matter is required a double-strip roll may be employed. It is obvious, too, that the roll or paper-supply may be suspended at some convenient place remote from the hand writing-board instead of being mounted directly thereon, if desired.

The invention comprises generally certain peculiarly-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 such other parts as may be required to make up a complete device, all as hereinafter explained.

The hand writing-board frame may be of any suitable form or style, that in the drawings consisting of side pieces 1 1, connected by cross-pieces 2 and 3, a hand-rest 1, having side pieces 5 5, which are supported by the side pieces 1, and a writing-bed 6, located back of the rest a between the side pieces 5, a slot 7 being left between adjacent edges of said rest and bed. The front edge of the bedthat is, the edge which forms the rear side of the slot 7is 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 guideplate S, curved upward at its front terminal, extends between the sides 1 from a position beneath the large roller 9 forward below the bed 6 to the slot 7, the inside face of the upwardlycurved 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 let. It will now be seen that the marginal rollers 12, while acting upon the paper as it passes between them and the roller 9, in no case come in contact with any other portions of the paper than the margins thereof, thus obviating all danger of 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 roller9. Thelower roller 1& 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) 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 or 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 20 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 paperroll 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 20 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 when the paper is unwound. Since the ears 27 are fast to the rod 24, it is thereby held against rotation in spite of the rotation of the roll 22 and the pull of the paper drawn over said rod in the mannerdescribed below. The holders 20, with the shaft or trunnions of a paper supply-roll, may be said to constitute the paper-roll holder.

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 offered 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 by 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 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 providing the necessary amount of tension. 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 or more has been written to bring a fresh portion of paper into position for more writing. hen ink is used, no blotter is required, for the reason 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 its parts without departing from the nature of said invention. For example, the hand-rest 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. Then, again, any suitable substitution may be made for the specific tension appliance herein set forth, or such appliance may be omitted altogether.

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

1. The combination with a hand writingboard provided with a suitable writing-bed around the front of which paper may be drawn, of feed mechanism comprising a feed-roller, 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 into resiliently frictional contact with the marginal rollers or with the paper between.

2. The combination with a hand writingboard provided with a suitable hand-rest and Writing-bed with a slot between, of feed mechanism comprising a feed-roller, 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 resilien tly frictional contact with the marginal rollers or with the paper between.

In testimony whereof I have signed my name to this specification in the presence of two sub scribing witnesses.
