JOHN ANDERSON RUFFIN, OF NEW YORK, N. Y., ASSIGNOR TO THE HAMMOND TYPEWRITER (10., OF NEW YORK, N. Y.

TYPE-WRITER.

Specification of Letters Patent.

Patented Aug. 29, 1905.

Application filed September 14, 1904. Serial No. 224,435.

To all whom, it may concern.-

Be it known that I, JOHN ANDERSON RUF- FIN, a citizen of the United States, residing at New York city, New York, have invented certain new and useful Improvements in Type- Writers, of which the following is a specification.

My invention relates to type-writers, and particularly to a supply or winding roll for the material to be printed upon, the said winding-roll being arranged in appropriate relation to the paper-feed mechanism, so that the operation of the said paper-feed mechanism will draw the paper or material to be printed upon from the said supply or winding roller.

I have shown the invention as embodied in the form of machine known as the Hammond; but it will be understood that I do not wish to limit myself in this respect.

The invention consists in the features and combination and arrangement of parts hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view through the paper holder or cylinder of a Hammond typewriter; and Fig. 2 is a cross-sectional view through the said paper holder or cylinder, this View showing also a part of the printing mechanism and the paper-feed rolls. Fig. 3 is a view of detent mechanism associated with the winding-roll, and Fig. 4 is an end view of the winding-roll and its supporting-bracket.

In a machine of the type known as the Hammond, in which the paper is contained or coiled in a paper receptacle or cylinder forming part of the paper-carriage, difficulty is experienced when thick paper or cardboard is to be printed upon, owing to the fact that such material is so stiff as to resist proper coiling within the paper-cylinder when manipulated through the feed-rolls in the ordinary manner. I have sought to provide means for overcoming this difficulty in this type ofmachine, and with this end in View I arrange within the paper holder or cylinder a winding or supply roller adapted to receive the end of the cardboard or stifi' paper when it is inserted between the feed-rolls, so that by tu rning the winding or supply roller the paper or cardboard will be wound upon the said roller and drawn down between the ordinary feedrolls until the proper point on, the said paper arrives at the printing-point, and then when the feed-rolls are operated to raise the paper for the line-spacing the said paper will be drawn from the supply-roll, which latter turns step by step as the line-spacing actions occur.

In the drawings, 1 represents the end frames of the paper holder or cylinder of a Hammond type-writer, these frames having between them a cage 2, preferably formed of wire-netting and of substantially cylindrical shape and constituting the paper-holder proper. The feed-rolls are arranged, as ordinarily, at 3 3 at the top of the paper-cylinder and when turned raise the paper step by step to present different portions to the printing-point between the shuttle 4 and the hammer 5. Within the paper-cylinder I arrange the supply or winding roller 6, Which is journaled centrally in the said cylinder, the bearings for the roller being provided by brackets or arms 7 attached to the outer side of the end frames by means of pins 8 on the end frames entering openings in the brackets and thumb-screws 9 passing through the brackets into the end frames. The winding or supply roller may be turned at will by a handle or finger-button 10 on the end of its shaft 11. The winding-roller is provided with a deep groove 12 extending longitudinally thereof and having a flaring upper portion or mouth at 13. This is normally presented upwardly, as shown in Fig. 2, and when the feed-rolls 3 are separated and the paper dropped between them, as in ordinary practice, its lower edge will be received by the deep groove 12, and then by turning the winding-roller the paper or cardboard will be wound thereon, as indicated in Fig. 2, and drawn down into position between the parts of the printing mechanism. The paper will thus be coiled or wound within the paperreceptacle and is drawn therefrom, as in ordinary practice, by the successive operations of the feed-rolls 3 3, and during these feeding actions the winding or supply roll will rotate step by step as the feeding actions occur.

In order to center the winding-roll so that the flaring mouth 13 will be normally presented upwardly, I provide a detent, consisting of a pin 14, having a conical end adapted to enter a conical recess in one of the brackets 7, the said pin passing through the end plate 15 of the winding or supply roll and being headed at 16 on its inner end to bear on the inner side of the said end plate and limit its cylinder, feed-rolls at the top thereof, a windoutward movement. The pin is pressed by a spring 17, arranged in a socket 18, formed in the winding-roller. The relation of the parts is such that when the detent is engaging a recess in the bracket 7 the flaring mouth 13 will be directed upwardly to receive the lower edge of the paper. While the detent is sufliciently strong in its action to hold the supplyroller, it will yield freely when the paper is fed upwardly by the feed-rolls. By means of this detent the operator can readily determine when the winding-roll is properly set, the pressure or force necessary to turn the button 10 being slightly greater when the detent is in action or is engaging the recess in the bracket 7 than when it is free therefrom.

I prefer to make the winding roller of wood, with the end plates 15 of metal and screwed thereto.

I may also utilize'the winding-roller as a means of providing a series of stops'or rests for cards'of different sizes, and for this purpose the said roller is provided with a series of slots or grooves 16 These are of different depths and provide means for supporting cards of different sizes when brought beneath the opening between the feed-rollers. The

winding-roll may be set rigidly in position topresent any one of the series of grooves in line with the feed-rollers by means of a thumbnut 19, engaging a screw-threaded pin or journal 20, extending from one of the end plates or heads 15, as shown at Fig. 1.

I claim as my invention 1. In combination in a type-writer, a papercylinder', feed-rolls at the top thereof and a winding and supply roll arranged within the cylinder having means to automatically grasp the paper and wind the same when the roll is turned, substantially as described.

2. In combination in a type-writer, a papercylinder, feed-rolls at the top thereof and a winding and supply roll arranged within the cylinder having means to automatically grasp the paper and wind the same when the roll is turned, said means consisting of a groove to receive the edge of the paper, substantially as described.

3. In combination in a type-writer, a papering-roll within the cylinder, having means to automatically grasp the paper and wind the same when the roll is turned, and detent means for holding the roll with said automatic means in position to grasp the paper, said detent means being adapted to be overcome by the feeding action of the feed-rolls, substantially as described.

4:. In combination, a paper-receptacle, a winding-roller therein, brackets in which the said roller is journaled, said brackets being secured to a part of the paper-receptacle, and a detent between the roller and one of the brackets, said roller with its brackets and detent being removable as one body substantially as described.

5. In combination, in a type-writer, a roller having a plurality of rests or supports at different heights to receive the paper and printing mechanism, substantially as described.

6. In combination, with printing mechanism, a roller having a plurality of grooves of different depths to receive and. support the paper, substantially as described.

7. In combination, with printing mechanism, a roller having a plurality of supports of different heights, and means for holding the said roller in any position to which it may be adjusted, substantially as described.

8. In combination, with printing mechanism, a roller having a plurality of supports of different heights, and means for holding the said roller in any position to which it may be adjusted, said means consisting'of a clampnut, substantially as described.

9. In combination in a type-writer, a papercylinder, a winding-roller therein, having a rest for the lower edge of the paper and means for grasping the paper and winding the same when the roller is turned, and feed-rolls associated with the paper-cylinder for unwinding the paper from the winding-roller substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN ANDERSON RUFFIN.
