SPECIFICATION forming part of Letters Patent No. 784,295, dated March '7, 1905. Original application filed December 15, 1903, Serial No. 185,294. Divided and this application filed March 10, 1904. Serial No. 197,417.

T0 (071/ Iv/1.07711 it may concern:

Be it known that I, OnARLEs J. BELLAMY, a citizen of the United States of America, residing at Springfield, in the county of Hampden and Commonwealth of Massachusetts, have invented new and useful Feeding Mechanism, (the same being a divisional part of an application for United States Letters Patent'filed by me December 15, 1903, and serially numbered 185,294,) of which the following is a specification.

My invention relates to improvements in mechanism adapted to handle such fabric as paper from a roll for use with handwritingboards, type-writers, &c.; and it consists, essentially, of a certain peculiar tension appliance, as hereinafter set forth; and the object of my invention is to provide a tension appliance for a fabric-roll and the fabric itself after it leaves the roll which is simple in construction and operation, practicable, and efficient. One particular advantage of this appliance resides in the fact that the action of the same is quite positive, since the tension member is fixedly journaled, while in operation at least, and the fabric-roll is journaled in slots and kept in frictional contact with said tension member regardless of the size of said roll, so there is no chance for lost motion. 1 attain this object and secure this advantage by the means illustrated in the accompanying drawings, in which- Figure 1 is a side view of my invention, showing it applied to a certain handwritingboard; Fig. 2, a central longitudinal vertical section through the same, .and Fig. 3 a sectional view showing achange in arrangement of some of the relative parts seen in the two preceding views.

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

A single-strip roll of paper is described as being used in connection with this appliance; but it is to be understood that when a duplicate of the written matter is required adoublestrip roll may be employed; also, that the mechanism is useful for handling other fabrics besides paper and in other connections as well as with a handwriting-board or other writing device or machine. Furthermore, the

supply-roll and tension member may be supported at some convenient place remote from the frame of the device which is making use of the fabric from the roll instead of being mounted directly thereon or therein, ifdesired. The novel features of the handwriting-board made use of merely for the purpose of illustrating a practical application of the present invention form no part of said invention, but constitute the subject-matter of the application of which this is a division.

Proceeding now to briefly describe the aforesaid handwriting-board, attention is called first to Figs. 1 and 2 of the drawings, in which it will be observed that a suitable frame consisting of side pieces 1, connected by a floor 2 and a cross-piece 3, and of a hand-rest 4 is provided. A part of the hand-rest4 consists of a lid 4, hinged at 5 to the fixed portion of said rest. A lug 6 on the inside face of each side piece 1 receives the rear end of the lid 4 when closed. Upon opening the lid 4 access is had to the interior front portion of the device, thereby enabling the paper to be readily adjusted on the platen 7 or said platen to be removed. The roller or platen 7 in the present instance consists of an eight-sided block having a shaft 8 journaled in the bottom of a slot 9 in each side piece 1, pins 10 and eyes 11 being employed to hold said shaft in place. \Vhichever side of the platen 7 happens to be in approximately the same plane with the hand-rest becomes for the time being the real Writing-bed. The platen 7 is rotated by a knob on one end of the shaft 8, such knob being represented by the dotted lines 12 in Fig. 2. The pins 10 are withdrawn from the eyes 11 and the lid 4 opened when it is desired to remove the platen. Either a long roller or two short marginal rollers 13 are carried by a shaft 14, journaled in slots 15 in arms 1, extending upward from the side pieces 1 and connected by a cross-bar l". The rollers 13 are pressed against the platen by means of springs 16 in the slots 15, such springs being interposed between bloeks 17 and 18, slidingly mounted in the arms 1. The blocks 17 bear directly upon the shaft 14, while the blocks 18 are forced by the springs 16 against the ends of ad justing-screws'lQ, threaded through openings in the upper ends of said arms. A long roller has its shaft 21 journaled in slots 22 in the side pieces 1, and springs 23 in said slots force said roller against the platen. The springs 23 are introduced between blocks 24 and the bases of the slots 22, said blocks being slidingl y mounted in said slots and bearing tendency of such roll-holder at all times.

against the shaft 2]..

A description of the novel features of the present invention as embodied in the handwriting-board hereinbefore set forth will next be given.

Oblique slots 25 are provided in the side pieces 1 for the trunnions or shaft 26 of a paper-supply roll 27, and such slots are narrowed at their lower terminals, as shown at 25, to afford bearings for the trunnions or shaft 28 of a tension member 29, which may be either a rod or a roller. The roll 27 is drawn into contact with the tension member 29, which in this case is a roller, and so remains as said roll decreases in size by the unwinding of the paper 30 through the medium of a spring 31, extending between each outer end of the shaft 26 and a pin 32, projecting from the outer face of the corresponding side piece 1. By releasing the shaft 26 from the aforesaid springs said shaft, with the paper thereon, if any, may be readily removed from the slots 25, also the shaft 28, with its roller 29, as will be readily seen. It will not, however, generally be necessary to remove the roller 29 from its normal position unless it is required to enlarge the space back of the roller 20, so as to enable the operator to more readily insert the end of the strip or web 30 from the roll 27 into the bite of said roller 20 and the platen. It is to be understood that the tension member 29 is so positioned as to divert the course of the web 30 on its way from the roll 27 to the platen. The tension member may or may not revolve. Y

Of course weights might be substituted for the springs 31 or gravity depended on to retain the supply-roll in constant contact with the tension member, in which last event the roll holder or shaft 26 must be heavy enough and the bearings for the same steep enough to insure a sufiiciently-forceful downward It maybe noted, too, in passing that any suitable roll-holder may be employed. I do not herein seek to cover a resistance device operating only during the increase of size of a fabric-roll if such should take place, but wish to include as part of my invention a tension device operating during both an increase and a decrease of the size of said fabric-roll.

In operation the web 30 after passing upward between the roller 29 and the roll 27 and partly around the former extends forward between the platen and the roller 20, thence around the front of said platen, and finally rearward between the platen and the marginal rollers 13. The hand of the operator rests upon the parts 4: and 4*; but the writing is done on the adjacent exposed side of the platen. direction of the arrow in Fig. 2 from time to time, as required, to bring other sides into service and fresh portions of the paper beneath the pen or pencil of the operator. The rollers 13 and 20 assist in actuating the paper and controlling the platen. The rollers 13 also obviate blotting the written matter when ink is used. During the operation of the mechanism the roller 29 is to all intents and purposes fixedly journalcd that is to say, it does not slide in its bearings. Hence the point where the paper leaves said roller always occupies the same relative position to the bite of the platen and roller 20, with the exception of whatever slight variation there may be owing to the irregular outline of the platen and consequent up-and-down movement of the roller 20. The springs 31 provide the necessary tension for the roll 27 and, with the roller 29, afford the desired degree of tension for the web 30.

The modified arrangement shown in Fig. 3 consists simply in changing the positions of the slots 25, so that the roll 27 and the member 29 can be located in front of the platen instead of behind it. Each pin 32 for one of the springs 31 in this case is placed higher than before and in advance of its former position. The slot 25 in each side piece 1 turns downward at its forward end and opens through the bottom of said side piece, as shown at 25 ,,t0 provide convenient means for removing and replacing the shaft 26, an opening 2 being provided in the floor 2 for the passage of the supply-roll. The crosspiece 3 and the roller 20, with its appurtenances, are omitted from the modified construction, although the roller might be retained, if desired; otherwise the parts are the same as has already been fully explained. The web 30 after leaving the roll 27 and passing partly around the tension-roller 29 extends upward and rearward directly onto that side of the platen 7 which is serving as the actual writing-bed, and then its course is the same as before, as is the operation of so much of the mechanism as is here retained.

Various other modifications in arrangement will readily occur to one skilled in the art, modifications which do not depart from the nature of my invention.

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

l. In feeding mechanism, the combination with fabric-actuating rollers,of a tension member, and a rotary fabric-supply-roll holder mounted in movable bearings and it or the roll thereon in resiliently-frictional contact with said tension member, the line of such contact marking the line from which the fabric separates from its roll in process of feeding, the tension member being fixedly mount- Said platen is rotated in the.
