To all whom it may concern:

Be it known that I, JOHN BARR, a subject of the King of Great Britain, residing at marked .with thewhole Dinting, in thecounty of Derby, England,

have invented certain new and useful IIn-' provements in Apparatus for Producing Lit.- erature for the Blind, of which the followingis a specification. a

his invention consists of a machine constructed on the principle of Shields pantograph engravingmachines, United States Patent No. 28,332, of 1860, and Crosslands English Patent No. 341 of 1896, and is designed to adapt such machine for printing or reproducing literature for the blind in the Braille or similar characters.

The invention willbe fully described with reference to the accompanying drawings.

Figure 1 is a side elevation, partly in sec-- .tion; and Fig. 2 is a plan of sufficient of the machine to illustrate the invention. Fig. 3

is an enlarged sectionalelevation of the moving bed F, the punches G, the indented roller- H, and the several parts adjacent thereto.

The machine is constructed with a table A, upon which is placed-a plate a, punched or or with a literary production written'with Braille points or indentations. Over the table A a pointer Ois mounted,capable of being moved in either direction over the table and of being lifted and lowered tocause it to 'engage w1th any of .the Braille points of the plate a. The pointer C is connected with slotted guides'or cams D D D common to a by which the movements of-the ointer'are transferred to and reproduced in t e slides The slides E move to and. fro as the pointer C-is moved backward and forward over the plated on the table-A, and upon these slides rest the ing-shaft e, and

and fro the disks E" andthe shaft 0 are ro- *tated.- The bed F is driving-disks E, fixed to the ends of the drivas the slides E are'moved to moved to and'fro transversely as the pointer O is movedto one side or the other across t v e plate a on the table.A.- Upon" the transversely-moving bed- F are mounted one, two, or more stands or brackets F, carrying punches by Whichthe work of re 'roductionisperformed, as\described in t e specifications of Shields Pas out N 0. 28,332, 0f 1860,and Grosslands Eng lish Patent No.

The indented roller His rotated bac ward and forward by the driving-shaft'e and driving-disks E as th The perforated roller H of anyconvcnient length is divided into one, two, or more, preferably three, lengths, each the length of a sheet of Braille writing-paper or other convenient size of sheet. represent, therefore, three sheets under operationat the same time.

Where more than one punch is employed, they operate simultaneously toeach to produce a separate sheet of theprinting or literature. The point of shape with that 0f.a.

What I claim as :my invention, and desire "to protect by Letters Patent, is

1. In a 'pantograph engraving-machine,

- the combination with the Work-table A, the

pointer -'C moving over same, the slotted guides 13, D, D, the movable slidesE and rotatable disks E and shaft e' of a plate a .formed with Braille points pl need upon the table A, and a Braille roller ll provided with indents h upon which the paper to vbe marked is placed, mounted upon the shaft 6 and rotated by the movableslides E, and punches G to indent the paper, substantially as described.

2. In a pantograph engravingqnachine the combination with the punches G, punch-lever 'g, movingbed F and movable slides E, disks Y-rotnted thereby and in cans i or actuating the same, of a Braille roller l-l provided with indents-lt mounted upon and rotated by the'movable-slides E and disks E, and Braille plateplaced upon the operating-table A, sub stantially as described.

3. In a pantogrnph em raving-mnohine the combination with the punches (i. .puni-h-leversg, brackets 11" movable bed F, movable. slides and disks E thereon and means for actuatii'ig the same, of a Braille roller l'l provided with indent-s I). mounted upon the shaft e and rotated by the disks it, substantially as described.

4. In a .pan'tograph engraving-n1aehine,

the combination with the punches (i. punchlevers g moving bed F and movable slides l'l and means'for actuating the same, of an indented Braille roller ll, mounted inpon and rotated by the movable slides E, and d irided into anumber of-sections or lengths each the length-of-asheot of Braille writ ingpa 01. substantially as described.

In witness whereof I have hereinn o signed any n ame in the presence of 'two su hscri hing; Witnesses.
