TYPE-WRITING-MACHINE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 554,831, dated February 18, 1896.

Application filed June 10, 1895- To all whom it may concern.-

Be it known that I, PETER F. NILsoN, a citizen of the United States,residing at Phoenix, Maricopa county, Territory of Arizona, have invented an Improvement in Type-Writer Attachments; andI hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the general class of typewriters and especially to an attachment therefor, the object of which is to enable the machine to write upon the pages of bound books, pamphlets, pads and other folded sheets, as well as upon ordinary sheets of paper.

My invention consists in the novel holder for the book, pamphlet, pad or paper whereby it is presented in proper position to the action of the type and in the necessary adjustments and means for efiecting them, whereby the position of the holder is varied as required, all of which I shall hereinafter describe and claim.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a front elevation of my device. Fig. 2 is a rear elevation of the holder 0. Fig. 3 is a horizontal section on line as x of Fig. 1. Fig. 4. is a vertical section on line 114 of Fig. 1. Fig. 5 is a detail of the backing-plate N.

A is a frame in which is mounted and adapted to travel sidewise a carriage B. The carriage is mounted in the frame in any suitable manner, and for this purpose I have here shown it as being hung by suitable eyes I) from a track a above, and moving by means vof suitable guide-studs 1) below in a slotted way a in the bottom of the frame A. The movement of the carriage may be effected by a spring or a weight,as may be desired; but for this purpose I have here shown a weight W connected with the carriage by a cord w which passes over suitable guides, and said weight may be suitably housed in a tube w at the side of the frame A.

Mounted in the carriage B and adapted to move vertically therein is a holder 0. This consists of a main frame, to the front of which Serial No. 552,308. (No model.)

is hinged a door-frame c, said door-frame being open in front and adapted to be held to the main frame by a suitable catch 0 at the side opposite the hinges. This front or door frame has traversing it vertically holdingstrips 0 which are so arranged that the middle one occupies the central plane between the leaves of a book, pamphlet or pad, which is represented by D, while the side holdingstrips pass over the margins of the pages of the book, pamphlet or pad, thereby leaving the central spaces of the leaves free for the reception of the type-impressions. The book, pamphlet or pad is held forward against these front holding-strips with a sufficient degree of pressure by means of a back plate E made in one or more sections, as the case may be, here shown as made in two sections, said plate or the sections thereof being adapted to be set up by means of pressure-screws F from the back of the holder-frame C.

By opening the door-frame c in front the book, pamphlet or pad may be placed in an open position with its back against the sections of the back plate, and then the doorframe is closed against it and is locked in position, whereby it is held with its sheets presented outwardly. It is to be understood that this holder-frame for the book may be of a size suitable for the book, pamphlet or pad intended to be written upon, and to this end it may be made adjustable or variable in size to receive different sizes of books. It is to be understood also that ordinary sheets of paper may be placed in this holder and written upon.

The necessary vertical movement of the holder, in order to present different lines to be written upon, is effected as follows: The main frame 0 of the holder is fitted to side guides 17 in the carriage B, and said frame is suspended by a cord G passing up over a spring-controlled pulley g in the top of the carriage B, whereby the tendency is to pull the holder 0 upwardly constantly. On the side of the frame 0 is a feed-rack H with which a retaining-pawl I, pivoted on the carriage B and controlled by a spring i, normally engages. A feed-pawl J, pivoted to the carriage 1'3, has a tail extension j, which is adapted to lift up under an arm i of the pawl I so that as the feed-pawl J is thrown forwardly to engage with one of the teeth of the rack ll its tail extension, acting on the arm 21, will withdraw the retaining-pawll from said rack, and upon the next movement as the pawl J withdraws and the pawl I advances the holder will rise one tooth in the ordinary manner of feeding mechanisms of this class. The feedpawl .I is operated by a hand-lever K pivoted to the side of the carriage B and connected with said pawl by a link 7:. The teeth of the rack II are so arranged that they will slip down past the retaining-pawl I, so that the holder C may be pushed down to its lowermost limit to present the top of the page of the book or other sheet to be written upon to the action of the type. \Vhen one line is complete the lever K is operated, and through the feeding mechanism the carriage is allowed to ascend one or more spaces to present a fresh line to be written upon.

The lateral movement of the holder with the carriage B is effected in the ordinary manner of type-writing machines, and to illustrate this I have shown, in connection with my attachment, a form of key letter-bar and escapement already known, and which constitute no part of my invention.

I have deemed it necessary to show but one key and letter-bar, though it is to be understood that a full set will be used.

L is the key and l the type or letter bar affected by the key and adapted to be thrown upwardly against the paper or book to be written upon. The keyin pressing down depresses the space-bar M, which, through suitable connections, operates the pawl or pawls indicated by m to engage with the escapement or rack bar 'm on the carriage below.

N is a plate, of metal, rubber, or other smooth hard material. It is ad] ustably hung by removable hooks from the top bar of the holder-frame, and is adapted to be inserted behind the page, leaf, or sheet being written upon, to furnish a firm backing therefor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with the type and typeactuating mechanism of a type-writer, a verticallydisposed carriage having a track at its upper portion and a guide at its lower portion, means actuated by the key mechanism of the type-writer for effecting the lateral travel of said carriage, a vertieally-slidable holder suspended from said track, with its lower end engaging said guide, said holder adapted to receive an open book, pamphlet, pad or sheet of paper, and present its face to the action of the type, and comprising a main frame, a front or door frame hingedly connected at one side with the mainframe and adapted to be opened and closed to receive and to permit the removal of the book, pamphlet, pad or paper,

and holding-strips across the front of the doorframe suitably disposed to present the paper to be written upon in a flat position, and means whereby the holder is intermittently moved upwardly in the carriage to provide for different lines.
