PAPER-CARRIAGE FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent N o. 763,165, dated June 21, 1904.

Application filed May l1, 1901. Renewed April 18, 1904. Serial No. 203,804. (No model.)

To (ZZZ whom, t may concern:

Beit known that I, JOHN H. DORMAN, acitizen of the United States, residing at New York, State of New York, have invented certain new and useful Improvements in Paper-Carriages for Type-l/VritingMachines, of which the following is a speciiication.

My invention relates to that form of typewriting machines known as the Hammond, and particularly to the paper-carriage of said machines, my object being to provide an extended form of carriage adapted to permit special werk to be done requiring wide papersuch, for instance, as insurance-tables or the iftables and statements made up in railroad-of- My invention includes a paper-carriage of extended form having a paper-roll of elongated form, together with supporting means for the said roll arranged intermediate the ends of the paper-carriage, said medial supporting means serving' to hold the intermediate portion of the roll in proper position, so that the paper will be properly fed at all points along the roll and whereby also narrowsheets of paper may be used in the machine, as well as sheets which reach from end to end. I have provided a special form of the intermediate support adapted to permit the accurate adjustment of the paper-roll at its middle portion, so that at this point they feed of the paper will be as accurate and certain as that taking place at the ends of the roll where it is held in its bearings.

One feature of my invention relates to means hy which the extended form of paper-carriage may be adapted to existing forms of the Hammond machine.

1While I show and describe my invention as applied tothe Hammond machine, I do not wish to be understood as limiting myself to the application of my invention to this type of machine. Y

In the accompanying drawings, Figure 1 is a rear View of so much -of the paper-carriage of the Hammond type-writer as is necessary to a clear understanding of my invention. Eig. 2 is a cross-section on the line 2 2 of Fig. l. Fig. 3 is a detail sectional View of the adjustable bracket or support for the intermediate part of the paper-roll. Fig. 4 is a bottom plan view of the supplemental' frame for formingan extension of the main frame to provide a support for the extended carriage. Fig. 5 is a detail plan view. Fig. 6 is a detail view showing how the two sections of the large roll are connected. Fig. 7 is a' similar view of the small rolls.

In the drawings, a. represents the carriagefrarne, and b and c the paper-rolls. The rear roll Z is carried byarms CZ, supported on the back bar e of the frame, the arrangement being such that the arms Z can have a swinging movement to move the roll b toward and from the roll a. This paper-roll b is of elongated or extended form, having intermediate of its length a space in which is located amedial'support f. This support comprises an arm held by the back bar c and havinga bearing for the intermediate portion of the elongated or extended roll. The back bar at this point is also supported by a medial supportingpiece, and this is in the form of a curved frame or bracket of a shape substantially that of theend frame-that is, being curved to conform to the cross-sectional shape of the paper-receptacle and having a bearing on its front side for the paper-roll e. By means of this intermediate arm and bracket the roll of extended form is supported intermediate of its length, so that the action of the roll at this point will be as certain and as accurate as that taking place at the ends of the roll in feeding the paper. In order to provide means for adjusting the roll at this intermediate position, I provide a special construction of the medial supporting-arm. In Fig. 3 it will be seen that this arm is formed in sections. One section, g, is pinned rigidly to the back bar and the other section, Zt, has aconcave seat at its lower end fitted to the said back bar. Seetion Zt is carried by the section g by means of a screw z', and at its upper end it is provided with a bearing 7c for the journal of the paperroll. This bearing is formed between the see- 95 tion Zt and a block Z, carried thereon, by means of a screw m. A forcing screw n passes through the section g and has its conical point resting in a cavity of the section It will now be seen that by loosening the screw and setting up the forcing-screw ai, the whole section /1/ will be moved away from the section g, and as this section is rigidly held upon the fixed back bar e the section l/L, together with the intermediate bearing for the paper-roller, will be adjusted forwardly, and when the desired position is attained the screw 2' may be set to lock the parts [irmly together. I do not wish to limit myself to the form of roll. This may be of separate sections or it may be of one section provided with an intermediate space, it being understood that in any case the action of this roll is uniform and accurate. throughout its whole length. The supporting-arm, it will be noticed, is arranged on the back bar intermediate of the ears o of the medial supporting-bracket.

I have shown for convenience only one medial support; but it will be understood that I do not limit myself in this respect, as any numbcr'may be used as circumstances may require.

This extended carriage may be used on any of the machines of the Hammond type already constructed, and for this purpose I have provided a supplemental base-frame p, adapted 'for connection with the ordinary base-frame of the machine, such as I have represented at gin a general way. This supplemental frame isadapted to be attached by screws r to the under side of the rear portion of the ordinary frame, and it has laterally-extending arms s, lwhich carry at their ends supporting means for the ends of the elongated or extended carriage. These supporting means, in the present instance, I have shown as composed of rollers; but l do not limit myself in this respect.

As shown in Fig. 6, the large roll-sections are connected by pins t to move in unison, thus making this roll practically one body from end to end. The sections of the small roll shown in Fig. 7 need not be connected, as these sections are driven from the sections of the large roll.

I claim asmy inventionl. In combination in a paper-carriage for a type-writer, a paper-roll, swinging' arms at the ends of the same for supporting the roll and an adjustable swinging arm intermediate of the ends of the roll forsupporting the same, said arm being adjustable in relation to the swinging arms at the ends whereby the middle portion of the roller may be adjusted in relation to the end portions, substantially as described.

2. In combination in a paper-carriage for type writers, a pair of rolls for feeding the paper between them and supporting means for said rolls arranged intermediate of the ends thereof, substantially as described.
