To all whom it may concern:
Be it known that I, RoBnn'r MoNsKE, a subject of the King of Prussia, German Empcror, residing at Bucharest, in the Kin dom of Roumania, have invented new an useful Improvements in Apparatus for Printing Books in Type for the Blind, of which the following is a specification.
This invention. relates to an apparatus for the production of books in the so called Braille type for the blind,
Herctoforc in order to enable paper to be printed with embossed characters of this kind of type metal plates with the characters in relief had to be prepared, of which impressions were taken on paper by means of special presses. This method of operating had the disadvantage of being somewhat complicated.
The present invention relates to a method of printing books in embossed type for the blind by means of which blind persons are themselves enabled to compose the printingtype and to at once print off the same in a very simple manner.
By my invention the Braille points or dots of the characters for the .blind are themselves used as type, so that a blind person is enabled by grouping together these pointtype to form the separate characters and to combine these into words. The pointtypes consist of conical pins, which in being composed in rows on opposite sides of the a paratus to be presently described enable t e printingr of paper sheets to be eliected on both sides. he apparatus for carrying out this method of operating consists, mainly, of two plates connected together by hinge-joints, in which the characters to be formed of conical pins are composed in rows. By arranging opposite the row of letters of the one plate yieldin rubber strips on the other plate it is rendered possible by closing together the two parts to simultaneously print a sheet of paper on both sides. The sentences consistin of conical pins which are set on the inner si e in the correct manner for reading can be at once removed again in their entirety by the simple turning over of covers situated on the outer side of the folding plates.
The apparatus is distinguished b great rapidity of action in the printing 0 books and by an excedingly simple and durable construction, the arrangement being such that blind persons can Work the a paratus them selves Without the slightest hdlp from others,
so that by this means the blind are ofl'ered a new means of earning their livelihood without material expenditure. The cheapness of the new method of operatin arises mainly in that the embossed metal p ates heretofore requisite for the printing operation are entirely dispensed with and that the two machines heretofore re uisite-namely, one for embossing the meta plates and a press for taking impressions of the metal platesare reprl aced by a single a paratus.
he apparatus is s iown on the accompanying drawings, in which-' Figure 1 shows a perspective view of the same. Fig. 2 shows a plan, partly in section; Fig. 3, a cross-section; Fig. 4, a art section of the two composing-plates to a arger scale, the upper plate having the pins in position for the printin and the lower late showing the pins forcec out by means 0 the reversed cover.
' The apparatus consists, essentially, of two composing-plates a and t, which are connested together by hinge-joints c.
ranged alternative rows of rectangular recesses d and rubber strips or ads e, and these rows of recesses and rub er strips of the two plates c and b are so arranged rela- ,tively to each other that a row of recesses of the plate a is situated opposite a robber strip of t e plate I), and vice versa. At the bottom of each rectangular recess (I there are formed in the plates a and 1) six conical holes 0 or perforatiensdf, into which conical pins 9 can be inserte in such manner that they project With'their heads be end the inner surfaces of the plates at and i. 6., beyond the sides having rectangular recesses. means of suitable combinations of pins in these six conical holes there may be produced the several characters in the known manner. The recesses d enable the blind to readily locate each set of the perforations and also to 100 ascertain the beginning of sec line. For simplifying the composing operation it is of advantage to employ in addition to the separate pins definite combinations thereof by the connection of two and three of the pins I05 together, which are easily distinguished by the blind, so as to be employed by them in producing certain characters.
The arrangement of the characters and composition of the words is, however, in this 1 1o apparatus not effected as in other printing apparatus in a reversed manner, but in the On the 80 inner surface of the plates c and b are arcorrect manner for reading, as when a damped sheet of aper is introduced between the plates a and b for the purpose of embossed printing there will be produced, on pressing the latter together, the raised characters on the side of the paper opposite to that against which the pins are pressed, so that on that side the grouping of the embossed projections will a pear in the same order as the grouping of t e pins t. e.,in the proper order for reading.
In order that the paper to be printed upon when being placed between the plates a and b may readily be brought into a strai ht position, the sides of the plates are provided with raised edges 71. For facilitating the manipulation handles 11 are provided at the front of a and b. The thickness of the plates a and b is so chosen that the pins inserted into the holes 1 project to a certain extent be ond the outer side of the plate.
11 order to avoid an unintentional pushing out of the pins, there are provided on the outer sides of the plates (1 and l) guard-covers k, which at the one end are pivotally secured by means of pins m, engaged in open 100 s or slotted bearings n, andon the other en are secured by latch-levers 0. A handle p, fi ge d to the under side of the cover k, serves 30 for turning it over. The covers it also serve for another purpose. For the removal of the composed type for the purpose of composing the type for the next page of the book the covers it are drawn out of their loops and are replaced in an inverted position. By this means the outer side of the cover which is provided with a metal late is brought in contact with the rear en s of the pins 9 and presses the whole of the same out of their conical holes, as shown in the lower plate of Fig. 4. The pins can then be dropped onto a sheet of paper and be at once used again for composing the next age.
In order that the ru ber strips which are opposite the front rows of pins may be readily changed, they are let into dovetailed grooves ormed between the rectangular recesses of the plates and are secured at their ends by means of screws 8 and small holdinglates t, as shown. The edges of these 1101 1nglates at the same time serve to indicate to t e' blind person the position of the next following row of recesses.
It will be obvious that several of the abovedescribed apparatus could be secured togather side by side in such manner that after composing the ty es for a paper sheet in each apparatus and t en folding the connected p ates of the several apparatus together at the same time a corresponding number of paper sheets could be simultaneously printed on both sides.
