Description
PHOTOGRAPHY Filed NOV. 3.0, 1937 ENVENTOR 'a plurality ofthe pages produced Patented Nov. 19, 1940 UNITED STATES PATENT l oFFIcE 6 Claims.
This invention relates to the art of photography and particularly to the production, in
photographic form, of printed or written matter.
The broad objective oi this invention is to create, photographically. pages of reading matter, each of which is substantially similar to that produced by the art of printing. In the production of each photographed page, each line is optically justified-during and as a part of the photographic step. The type of the said photographed pages may be either of such proportions as to be easily read or it may be of micro size so that a vast number of micro size pages may be recorded upon a relatively small surface.
Bymeans of this invention it is possible to record photographically upon a single plate the contents of a printed book of four or five, hundred pages, thus effecting great economy in storage and transportation. The reading matter thus recorded upon such plates is rendered readable with great ease by means of the enlarging projector shown in the copending application o f Fetter, Serial No. 173,741, led Nov. 10, 1937. 'I'his broad object is obtained by several steps.
One of the steps of this invention is to produce in photographic form a page of typed or, written matter by separately photographing each line of such matter, and justifying each line during and as a step in the photographic process.
The next step to attain the broad objective of this inventionis -to produce a master positive upon which will be recorded photographically the pages previously created photographically, which, in effect, constitute the plates from which are made the records to be used in the Fetter projector mentioned hereinbefore.
Other objects of this invention will be apparent from the following description when read in connection with the attached drawing of which Fig. 1 shows an 4arrangement for photographing, in succession, each of a plurality of lines which have been typed or otherwise set up for display; Fig. 1a shows in fragmentaryform a detail of Fig. 1; and Fig. 2 shows means for producing a master record upon whichls micro-photographed by the apparatus of Fig. 1, so as to constitute a continuous record of the subject matter, the successive microphotographs upon the master record being preferably keystoned. e
At the left hand side of Fig. 1 is shown a line typewriting machine I which may be one of a plurality' oi well known types. 'Ihat machine comprises a keyboard having the usual keys for letters, numerals and symbols by means of which the subject Amatter to be written may be produced in line form upon a tape, as indicated by 4, at the side wall of the machine. The machine I has associated with it an indicator 3 which shows the number of letters, numerals, symbols and spaces that appear in the typed line 4. The indicator 3 may be controlled by the letter, numeral or symbol keys or the space bar of the typewriter in such way that the movement of such keys or bar to produce a corresponding eiiect upon the tape will cause the operation of the said indicator. The indicator may be restored to its zero setting by means of a knob at the side of the indicator casing which actuates gears or other mechanism within the 1ndicator. Other keys, shown at the right hand side of the keyboard and designated 5, 6, l and 8 control the operation of the mirro'r 9 and of the camera, the manner of doing which will presently be described.
The mirror 9 is positioned between the typewriting machine I and the camera I5 so that the image of the typed matter,upon the tape 4 will be reflected into the lens IU of the camera and therein will be photographically recorded upon a light sensitive plate or iilm I4. A framework I6, comprising two horizontal members and a vertical member, is designed to support the said mirror which is fastened to the said vertical member. The mirror may be of the same size as the vertical member, or it may be smaller, the essential thing being that the mirror shall be large enough to embrace the image of the typed line that appears upon the tape 4. The framework I6 is rotatably supported by the spindle il which passes through the said horizontal members. The upper member of said framework, which is semicircular in form, has a serrated edge which coacts with two pawls I8 and I9, which are adapted to be operated by the electromagnets 20 and 2i respectively, and, after operation, to be restored by springs 22 and 23, respectively. are supported in any suitable manner, as, for example, by a framework 24 which is so positioned that the pawls will engage the teeth formed by the serrated edge of the upper member of the framework I6. The electromagnets 20 and 2I are energized by the closing of a circuit containing a suitable source of power (not shown), the closing being eifected by the operation oi' the keys 5 and 6 shown at the right hand side of the keyboard of the machine I. When the key 5 is pressed the magnet 20 will be energized and that, in turn, will pull the pawl I8 toward it, thereby CTI The magnets, pawls and springs y 55 said plate that may 2 2,222,257 causing the framework I4 to move in clockwise ber Il, as shown in Fig. 1 and in enlarged form direction (when viewed from the top). The said in Fig. 1a. The movable member will press pawl 'will be restored by the action of the spring 22 so as to disengage the pawl and be ready for 5 the next tooth engagement.
In like manner. the actuation of the key C will energize the magnet 2i, which, in turn, will cause the pawl I9 to engage a tooth of the member I6 and will cause the rotation of that member in a counter-clockwise direction to the extent to which said pawl moves. By the retractile force of the spring 28 the pawl Il will be disengaged from the tooth, and will be held, disengaged, ready for the next tooth engagement.
The manner in which this apparatus functions will be clearly understood from the following illustrative case. Let it be assumed that each line of the nished product represents or contains a total of fty letters or spaces or a combination of both, which will :e considered standard. The mirror is normally set at such an angle for the assumed "standard length, that, if, 50 letters or spaces (or both combined) appear upon the tape 4, that line will be slightly foreshortened by the mirror so that the line upon the film will be of the correct length.
Now, let it be assumed that the total number of spaces and letters on the tape 4 is 4'1. Key B will then be punched three times and the mirror will be shifted to the correct position to optically lengthen the image of the line so that it will, when subsequently photographed, have the same lengthl as the "standard line. If, on the other hand, the line on tape 4 comprises 52 letters and spaces, key 5 will be pressed twice and the mirror will automatically take the position to optically bring that line down to the length of the standard" line.
This automatic adjustment of the mirror is at- 40 tained by correctly proportioning the size of the teeth in each quadrant on top of the member IB with respect to the number of spaces to be added or subtracted from each line to make its image equal in length to a standard line. In fact, 45 the teeth engaged by the pawl may have different spacings. so that the angle of the mirror will always be such as to give the correct length ot lineupon the camera. film or pla te.
When the image of the line 4 is properly justined the operator will then press key 1 which will operate the shutter of the camera and thus cause the said typed line to be photographed upon the negative I4, the light passing through a slit in the mask I3 which, of course, limits the area of the be exposed at any time. After the said line has been photographed, the operator will press the key l which operates the magnet I2 and thereby causes the carriage of the sensitized plate to move to the next line position. The extent of such motion is determined by the separation desired between successive lines upon the said plate. The camera is then ready for photographing the next line set up on the tape 4.
around'by the action of the magnets and the pawls, the said member will remain in any given position by virtue of the friction between the said member and the support around which it rotates.
After a line has been photographed it is necessary to return the mirror to its normal position. This is accomplished by operating key I2 which energizes the magnet il and causes the movable member 34 to move towards and against the curved back part of the lower horizontal side of mem- During the process of stepping the member IB against the curved edge until it brings the said member II back to its normal position. The releasing of the key I2 will deenergize the magnet 32 and permit the withdrawal of the member 24 from the curved part of the lower side of member I6, thereby permitting the rotation thereof by the magnets 20 and 2|.
When the number of lines required to fill a page have been photographed upon the plate I4, it will be removed and developed and thus made ready for use in the making of a master positive record, the apparatus for doing which is shown in Fig. 2.
In that figure, the negative I4 is supported by a suitable framework 24 which is preferably slidable so that the said negative may be brought in front of a lamp (or other light source) 25. The picture, viz., the page of printed matter, upon the negative I4 will be projected through the lens 24 upon the light sensitive surface of tho plate or film 28 in the camera 21, whenever the shutter 29 is opened. The plate or film 2l, which is shown circular in form, is supported upon a spindle 2li which is ilxedly mounted upon a disk 2l that projects through the side of the camera to such extent that it may be moved by the thumb and ngers. That disk, and its supporting member which preferably are of the same type as are shown in Figs. l and lb of the copending application of Fetter. Serial No. 173,741, filed Nov. l0, 1937, are designed and intended to move the sensisitized plate through an angular distance equal to the space required for photographing upon the plate 26 the matter appearing upon the negative I4. The disk Il is, likewise, designed to hold the plate 28 fixedly after it has been moved through the required angular distance, such holding being effected through the coaction of a pin and properly spaced holes in the said disk, all of which is fully shown in the said copending application.
In order to obtain the most eillcient use cf the sensitized surface 26 the successive positive pictures appearing upon the plate 20 should preferably be of micro size and may be keystoned. They should also appear upon the said plate in spiral form in order that, when subsequently projected by suitable apparatus the pictures. as thus projected, will follow in unbroken sequence. That result is obtained by means of the apparatus shown in Fig. l of the said copending application of Fetter. The same principles may be applied to the making of a cylindrical master record of the type shown in Figs. 4b, 4c and 4d of the copending Fetter application.
After the positive master record has been made in the manner just described, any number of negatives of such positive record may be made for use in the projection apparatus described and shown in the said copending application of Fetter. It is'fto be understood, of course, that the size of the film may be other than the micro size stated above. without departing from the scope of the invention.
It is to be further understood that the invention is not limited to apparatus of the particular form shown and described herein. For
example, the subject matter that is to be photographed by the camera Ilmay be hand-written: or it may be set up by type held in a frame in such fashion that the face of the type may be readily photographed. Furthermore, the mirror supporting means may assume a variety of different forms, the essential requirement being that it shall be Iable to vary at will the length of @the image of the typed or written material appearing in the camera. If desired, the mirror or a system of mirrors could be employed to vary the height of the letters appearing in the camera; and, furthermore, the size of the letters could be enlarged or reduced by the use of a lens or a system of lenses interposed between 'the typewriting machine and the camera. Other variations may be made without departing from the spirit and scope of the appended claims.
