HERBERT BRIGHT, F NEW YORK, N. Y.
To all 'whom #may concern.'
Be it known. that I, HERBERT L. BRIGHT, a citizen of the United States, residin at New York, in the countyV of New ork and-,State of New York, have invented new and`useful Im 'rovements in Type-Writer Attachments, o which the following is a specification.
This invention relates to typewriting machines and particularly to an attachment therefor.
An object of the invention resides in the provision of means for minimizing eye strain incident to lthe common necessity of shifting the eye from the key-board to the platen or cylinder when the operator wishes to observe or verify the writing as it is placed In view .of this purpose of the invention, I have devised a system of mirrors correlated whereby .the image of the writing or matter as it is placed upon the sheet may be exhibited prominently from the machine at a point in a common line of vision with the key-board, and through certain peculiarities of construction it is found practical to cause the image of the writing to appear in a magnified or intensified state in order that it will be properly visible to the eye of the operator.
Another object of the invention resides in the provision of an attachment of this character which Will consist of a system of mirrors which are adapted to be individually adjusted whereby they may be made to properly accommodate themselves respectively to the platen or Vcylinder and the keyboard.
Another object of the invention relates to a structure of this character which will include means whereby that mirror which is normally associated with the cylinder to receive reflections of the writing, may be conveniently adjusted away from the cylinder in order that the operatormay freely manipulate the writing sheet as the occasion may demand.
In the drawings forming a part of this specification and in which llke reference numerals indicate similar parts throughout the several views Fi re 1 is an end elevation of a typewritmg machine showing the applicationof the invention thereto.

Specication of Letters Patent. i Patentd Oct, 30, 191'?, Application tiled January 4, 1918. Serial No. 70,287;
Fig. 4 is a perspective view of one of the rocklng studs.
The invention is used in the present instance in combination with what is knownv -or pintles 4, are mounted to rock. These studs are provided with sockets or guide passages 4 and 5. The rocking or tilting frame l consists of sections 6 and 7, the former having parallel side arms 8-8 which are freely slidable in the guide passages 4. The mentioned arms may be vsecurely confined against sliding movement by set screws 9 carried by the studs or pintles 4. The frame section 7 consists of similar parallel arms 10-10 which are freely slidable in the passages 5 and they may be secured against sliding movement by setscrews or the like 11. p I
As stated, hereinbefore, I have employed a system of mirrors which may be associated, respectively with the platen orcyl-l inder and the key board so that an image of the writing as it is projected into one mirror may be displayed and observed from a common line of vision with the key board of the machine. In order that best results may be obtained, it is desirable to employ mirrors 12 and 13 which are arranged one above the other, the former being mounted for tilting movementsupon angular extensions 14 of .swinging sections 15 of the frame section 6. The mentioned sections l5 are pivoted at 16 to the upper extremities of the arms 8-8 and incident thereto it follows that the mirrors 12 may be expedi` be observed that this mirror can also be individually adjusted whereby to permit of-its being operatively related to the upper mirror 12. At this point it is deemed advisable to mention that the reflecting surface of the mirror 12 is on the under side of the mirror body and that the mirrored surface of the mirror 13 is on the upper side. rlhe mirror 13 is provided with a transversely eonvex display surface 19 and incident to this rather irregular or distorted' condition of the mirror, the image of the writing will be exaggerated or suitably enlarged to permit of its being readily observed without straining the eyes of the operator. The frame 1 may be extended whereby to cause the mirrors 12 and 13to be disposed at such selected points relatively of the platen or cylinder and the key board of the machine as may be found suitable to the taste of the operator. The mirror 13 is disposed directly above the key board and in a common line of Vision therewith so that the image of the matter or writing to be exhibited may be observed Without the operator having to Achange his eye'irom a. iixed point upon the key board.
rl`he pintles 4 are slidable in a horizontal direction in the extension 3 whereby the supports 2-2 may be made to operatively accommodate themselves to the sides of the typewriter frame. rl`hese studs may be held against movement in said extensions by means of set screws 3a.
`What is claimed as new is 1.A rlhe combination in a typewriting machine, of relatively adjustable mirrors, one of which being disposed in relation to the cylinder whereby the writing will be reflected thereon, the other mirror being adapted toreceive'the writing reflections from the first mirror and to visually display the same from the key-board.
2. The combination with a typewriting machine, of an observation mirror located in a common line of vision with the key-board and a second mirror located adjacent to the cylinder whereby the writing will be relected thereon, and means for adjusting said mirrors to cause the reflected writing upon the secondmirror to be displayed from the observation mirror.
3. rllhe combination in a typewriting machine, of an observation mirror located in a common line of vision with the keyboard, and a second mirror located adjacent to the cylinder whereby the writing from the cylinder will be displayed upon the said second mirror and reiiected therefrom upon the observation mirror.
et. The combination with a typewriting machine, of a longitudinally disposed tiltaaa-area .chine will be reflected upon one of the mirrors and reflected therefrom to the other mirror to visually display the same from the keyboard.
5. The combination in a typewriting machine, of a tilting trame carried thereby, said frame comprising two independent sections, means for adjusting either of said sections with relation to the other section, a swinging mirror upon one of the frame sections located in a common line of visionwith the keyboard, swinging members connected with the other frame section, and a mirror pivotally secured to said swinging section, and located adjacent to the cylinder of the machine whereby to receive the written reliections from the iirst mentioned mirror and to convey the same to the operator of the machine.
6. The combination with a typewriting machine, of vertical supports rising from the frame of the machine, laterally disposed longitudinally adjustable rockin studs tor the supports, a. frame upon the rocking studs, said :trame comprising two independent sections, means for adjusting either of the sections upon the studs, and a swinging mirror carried by each of the frame sections, one of said mirrors being located in a common line of vision with the keyboard and the second mirror located adjacent to the cylinder whereby the writing from the cylinder will be displayed upon said second mirror and relected therefrom upon the first 100 mentioned mirror, as and for the purpose set forth.
7. lThe combination in a typewriting machine, of the keyboard and a support carryingV reading matter remotely located rela- 105 tive to the keyboard and an optical system comprising two reflectors so located as to visualize an image of one of the two mentioned objects in the general direction of the other.
8. rlhe combination in a typewriting machine, of the keyboard and a support carrying reading matter remotely located relative to the keyboard, an optical system comprising two reflectors, a frame for supporting 115 the reflectors and means for adjusting the reflectors to visualize an image of one of the two first mentioned objects in the general direction of the other.
ln testimony whereof I aix my signature 120 in presence of two witnesses.
