Application med '.ttay 9,
To all whom t may concern:
Be it known that I, JOSEPH LAGUIONIE, a citizen of France, and "a resident of Paris, France, have invented new and useful llmprovements` in rlypewriting Machines, of which the following is a specification.
rlhis invention relates to a device applicable to typewriting machines to facilitate the copying of writing, letters, signs or the like.
llt is the object ot the invention to provide improved means to permit the direct copying of writing or printing matter, signs, or tracings on a typewriting machine and enable a single or a number of carbon copies also to be obtained.
l attain this object by means ot an apparatus in the form of a translucent or transparent roller which is rendered luminous by interior lighting or self-luminosity and intended to replace the solid rubber roller or platen such as is generally used in typewriting machines.
The invention consists therefore in the lirst place in substituting a transparent roller (such as glass) for the opaque roller usually used in typewriting machines and in utilizing this transparent roller for the striking of characters and for direct impression on the sample placed under the sheet to be reproduced. i
ln this manner the necessity of watching the keys and the text to be reproduced while the operator is typing is avoided. rllhus loss of time and the mental etl'ort required to retain the phrase in the mind and the omission and substitution of words isavoided. iClerical errors and errors `of punctuation are also avoided.
For use when making a plurality of copies, :necessitating the interposition of a great number ot sheets of paper, with interposed carbon sheets and the thickness of the sheets becomes such that the transparency is insuliicient to enable the matter to be copied, means cooperative with the aforesaid means have been provided, which means attains the advantages above enumerated. rlhe apparatus Jfurther comprises a second transparent, semi-transparent or opaque roller moved by the initial transparent roller or by the unwinding of the sample in the vview of the operator gradually as the copying advances.
'llwo devices are thus provided, the one utilizing solely the luminous striking roller for two copies, for example made directly 1923. Serial No. 637,900.
on the sample applied to the luminous roller, the other device utilizing the luminous roller with or without lighting, according to requirements, for the striking of the charac.- ters with the sample applied to and being unwound on theiopaque or transparent roller which is associated therewith. This additional roller can be of a diameter greater than that of the platen or of a small diameter with a rocking` movement for eliecting the movement of the sample.
Reference is made to the accompanying drawings which illustrate devices in accordance with the present invention.
Figs. 1 and 2 show two constructional forms of the transparent and luminous roller.
Fig. 3 shows the coupling of the luminous roller with a secondary opaque or trans-l parent roller in the'case where the direct transparency cannot .be utilized on the platen.
Figs. 4 and 5 are modified constructional forms of the means for actuating the two rollers.
Figs. 6 and 7 are two further constructie-nal forms shown in perspective comprising the luminous platen combined with the secondary roller and the controlling and actuating means therefor.
Fig. 10 is a-front elevation shown partly in section.
rlFhe roller A (Fig. l) may be constructed otany suitable transparent or translucent material such as polished or unpolished glass. rlhe ends are provided with milled knobs or manipulating members l and lighting means, such as 2, shown in ,this instance as electric incandescentlamps. It for any reason the surface .of the glass platen is considered to be too hard and it is desired to damp the shocks, the glass roller could be covered with a sleeve A" (Fig. 2) et" transparent or translucent Hexible material such as colorless rubber, Celluloid or like material.
The roller-above described is actuated in a typewriting machine as. an ordinary opaque roller.
lt is rendered luminous at the desired moment by interior lamps placed behind the exterior surface, the lighting being effected by a switch of any suitable type.
Where a multiple number of copies of lll@ l12 which has a rockable movement and luminous and, means to permit of 'or memorandum of the samp the sample isjrequired as very frequently In order to occurs necessitating the interposition "of a roller B it large number of carbon sheets, thus decrea's- 12 from contact with the roller B by means ing thetransparency, a transparent' or ofthe finger lever 14. The return movement o aque roller B may be used on which 1s of .the roller 12 into contact with the roller placed the sample to Abe reproduced, the B 1s effected by replacing the finger lever vposition the sample on the 1s necessary to separate the roller original sheets with the carbon .sheets then 14 so as to allow the springs 18 to act on the l being unwound on the 'transparent roller lever 13.
A which'forms the platen and becomes in From the foregoing description of Fi 6 this case an ordinary roller. it will be readily understood that the ro ler As it is necessary that the unwinding of A carries the original sheets upon which the the sample be effected'gradually as the origityping is to be effected, thaty the roller B carnal sheets are ladvanced asA the copying ries the sample to be copied and that its progresses, various means can be utilized for movement is determined by the rotation of actuating the rollers A` and4 B simultanethe roller A, thus insuring the upward ously. f movement of the original sheets upon which According to Fig'. 3 the coupling and the the typing is to be impressed.

In order to copy any simple sam le It will be understood that. by .actuating the sample is placed on the roller A with t e the platen A the roller B will also be acsheet to be impressed by utilizing the transtuated. parency in the interior of the roller or the In a modification this movement may be luminosity of the roller per se. effected by means of a belt 5 (Flg- 4) 0r In the casek of insufiicient lighting to by means ofa bevel gearlllg aS SllOWD at enable the operator to follow the sample 6 and 7y (Fig. 5) `\placed on the roller B when it is a 'matter of A preferred form, 1n which the SllppOIft multiple reproduction on the roller A the for the sample is arranged for use 1n combi- Separation 0f the rollers A and B' is such nation with the rollers and B, and QI that itis always possible to place the lamp adaptation to a typewrlting machine, 1S -19 behind the sample which by transparency shown in Figs. 6 an 10. will be readily read as on the luminous roll- The arrangement as a whole (Fig. 6)
