The platen 26 is adapted to support and guide the fllm 20, which may be fed thereover' by any suitable mechanism such as the reels 29 and lll and sprocket 3|, Figure 5.

Plates 42, clamped between spacer washers 43 on a cross bolt 44, act as separatorsbetween the levers 31, 31a, etc., and also retain the springs 48 laterally in position. s

'I'he Contact lever 31h shown in Figure 1, has a rearwardly extending arm 45 engaging an insulating block 48 on the upper resilient member f 41'of a Vnormally open switch or contacter 4 8.-

The two sides 41 and 520i the contactor 48 are f' provided with leads 53 and 54 for connection `in the proper control circuit of the tabulating machine 32, all the other contactors being ,provided with similar leads. vA conduit box or cover 55, Figure `5, may be provided to protect th`e wiring in place on the machine 32. l

It will be seen that the location of the second cross pinl 4| to the left of fulcrum pin 38,1to-

gether with the points of engagement of the` spring48 withthe lever 31h, cause the latter to be urged clockwise, clockwise movement however,

e being prevented by the engagement of the point of lever aw with the hun .2o. As the fum zo moves to the right, a protrusion '22 encountering the point of lever 31h raises the point, swinging the lever counter-clockwise and causing the arm 45h to close the contacter 48.

The lever 81c, adjacent lever 31D; alsov has rear arm 45e adapted to close a contactor 48 v when a protrusion on the film 28 moves under the point of lever 31c. The arm 45c, however, is directed angularly above the arm 45h. Simrvilarly the levers'31d and 31o lhave arms 45d and 45e adapted to close contactors 58 and 5| respec tively, the arms being directed at different anl Sles above the horizontal.

Thus, the entire bank of levers, while identical in their engaging points, spring and fulcrum arrangement, have their switch closing arms staggered progressively in groups. The present illustration shows the progressive staggering as occurring in groups of four levers, but it is obvious that a group may be made to contain six or other numbers of levers. The purpose of this group staggeringl is to permit the levers themselves to be verythin and closely spaced While allowing the contactors to be of ample size.

While the size of levers and related parts is` greatly exaggerated, in Figures 1k and 2, as previously noted, it will be evident that bythe structure, described a. large number of levers with engaging points closely spaced may be provided tively brings'the image into relief. The lm'is then washed and dried, the unexposed portions remaining as protrusions above the general level of the iilm surface.

'rneactuai height of uneI promisibn z2 is de-l pendent on the thickness of the emulsion, and when using the process for record purposes in I rconnection with tabulating machines an emulsion of substantial thickness may be provided in order to avoid the necessity for undue delicacy in the mechanical structure of the sensing means,

- Figures land 2. It will be noted however, the )arcs of swing Yof th points of levers 3111, 81e l. etc., are nearly tangent to the film 28, so that' as arprotrusion 22 moves .to the right and engages-l the point of lever 31h, for example, the latter is moved a distance much greater than the height of the protrusion.r In consequence, a comparatively small height of protrusion produces a comparatively large angular motion of the lever imparting ample motion to the end ofthe long arm 45h to eiectually close the contacter 48.

In order to effect the placing of protrusions .'22 on'the iilm 28 in `proper relation for\use with the sensing means Figures land l2, a device of the type illustrated inVFigures 6 and 'l may be used. Referring to Figure 6, a' normally light in practicel thereby allowing for operation by minute and closely spaced protrusions on lthe film but allowing the contactors to be of ample size to transmit the small currents called for in actuating the control,mech'anismsiorv instance of tabulating machines.

The positive lm is first exposed under -the negative, then developed, preferably in a nonvtanning developer, xed and washed in the usual manner.' The lm is then treated with a solution such as `copper sulphate, potassium bromide,

'potassium bichromate and' water, which selec" tight casing 58 has fixed thereinl a horizontal partition `51 'provided with a plurality of apertures 58 arranged in a pattern corresponding to that of the tabulating 'form. A suitable lens system 59 is mounted above'a window 88 in the bottom 8| .of casing 58. The lens 58 is adapted.

to focus a reduced image of the apertures' 58 on the film 28 which is disposed on reels 82 and l 83 in a suitable magazine 84, the magazine'being removably secured to the bottom 8|. A drive sprocket is provided v.with an exterior ratchet 88 operable bya pawl 81 on a lever 88 rotatably mounted on the sprocket shaft 88. A spring 18` normallyholds the lever 88 upward. A vertical plunger 1| extending through the bottom- 8| and top 12 of the casing 58 and provided with a finger button 13, overlies the lever 88 and is normally held upwardly on interior spring 14. When the button is depressed, the plunger A1| swingsth'e lever 88 downward against a stopg18, thus' revolving they ratchet 88 and sprocket 85 through -v a. predetermined angle and lfeeding the film 28 to the left a corresponding amount.

A tubular illuminating means 18`disposed above the partition 51, is so formed yas to overlie all the apertures 58, 4and is provided with a transformer 11 mounted in a rear chamber 18 of the casing 58.V Primary conductors 18 and 80 of the transformer 11 lead through' a normally open push button switch 8| to an exterior SupplyQrd 82 adapted to be connected to any suitable source of current.

Individual shutters 83 arempivotally mounted on rods 83 so as to normally block the apertures `58. Vertical rods 85 pivoted to levers 88 on the shutters 88, extend upward through

slots

81, 88 and 88 respectively in a support plate 88, a re',-

lease plate 8|, and the top or keyboard 12.4 The tops of the rods 8'5 are provided with keys 8,2. Tension springs 83, secured to' the bottom of the supportplate 90, urge the rods 85 forward and upward, normally'holding the shutters 83 in V closed positions. A11v angular tooth 84 is provided on each of the rods 85. Whena key, for example key 82a, is depressed, the downward movement of the rod 85a swings the shutter 83a clear of the aperture 58a as shown in Figure 6,`

the other shutters to the rear of 88a having been on the nlm 20.

cut away in the drawings to clarify the showing'. As the tooth 04a falls below the bottom of the keyboard 12, the forward pull ofn the tension spring 03a swings the rod 00a forward, causing the tooth 04a to move under the forward edge of the slot a' and hold'the shutter locked open when the operators nnger is withdrawn from the key 02a. In other words, depression of any key locks open the `corresponding shutter.

Obviously any desired symbols may be assigned tn the4 keys 02, and their number, arrangement and the corresponding patterniof apertures may be varied in any desired manner, depending on the system of recordings used with 'a particular type of tabulating machine; it will be understood'that the form shown is merely for purposes of illustration.

The release plate 0| is slidable oni the support plate 00 and has two extensions. protruding through the front of the casing 50. A release space, and due tothe small movement and low inertia of the sensing. members. records can be sensed at much higher speed than ispossible with large amount of data to be recorded in minimum other types of records'such 'as punched cards and v the'like, f

In some cases it maybe'desired to retain the original nlm as a master-record and to duplicate "the data for u se in the machine or machines. For this purpose the original nlm may be simply developed and used as a negative from which positives are made, afterwhich the 'positives are treated in the manner previouslydescribed.

bar 90 is secured to the extensions 95, and compression springs, 01 normally hold the release plate in forward position as shown. When the bar 00 is pushed inward the movement of release plate 0| swings the rods 00 rearwardly so that if any rods are in depressed position their teeth 04 are disengaged from the front edges of the keyboard slots 09, allowing the rods to be drawnv upward by their springs to lclose the correspondlng shutters.

In the preferred method of making a record, the bperator first depresses the various keys It corresponding to the desired pattern. thus locking open the corresponding shutters 00. 'As soon as theset-up is complete, the switch 0| is closed,

the latter illuminating only the open apertures. A reduced'lmage of the pattern formed by the illuminated apertures is projected by the lens 9 The switch 0| having been released, extinguishing the tube 10, threlease bar 00 is pushed to cause the shutters 00 to'close,

-f above.described negative by meansshown dia'- energizing the transformer l1 andthe tube 10,

. The nlm is pressed or squeezed between the roll- Y and the plunger 1| is depressed to feed the nlm and place the device in condition for making the f next record.

avoiding loss of time in making records and waste of nlm through errors. It will be noted, however, that' if for any reason it is' desiredA -to impress symbols individually, this can be done by operating the switch 0| and release bar 00 after each single depression of a key. Y

When a series of record pleted on the nlm .20 the latter may bev developed. a positive -madefrom it, and treated in the manner previously 4described to lcomplete the record for use with the sensing means, Figure 1, the protrusions 22 occurring on the nlm wherever an image of an illuminatedaperture l0 has been photographed.

Records made by the described process may be very small in area, the diminution being limited only by the minimum size to. which the parts of the sensing means may practically be reduced, which size as previously pointed out, may be brought-within .very low compass by accurate .;manu'facture. Obviously, the method permits a patterns has been corn-vx up'before exposure is obviously advantageous' in If desired,`2however, the negative itself may be subjected to the bleaching and tanning process,-`

then used directly to operate the sensing device,

in which case the latter isarrlanged as shown in Figure 4, wherein thecontactr 00 is of the selfclosing type and is normally held open by the bar 45 as the point of lever 01h rideson the upper surface of the nlm 20a. When the point' of 01h drops into a depression llaforming part of the record, th contactor closes automatically to energize its control circuit. When the negative is used in this manner the wiring of the sensing means is arranged to vcompensate for the. .reversal in relative positions of the data markings from that, occurring in the positive. From the above it is evident that the invention-comprises. controlling a sensing means by differences in thickness of the record, the controlling yfactors being either protrusions ondepressions.

Duplicate records may also be made from the grammatically in Figure,"9. In this'case the nlm' 20a, containingthe sunken portions or depressions 22a, subjected to a suitable bath 00, for

example, a solution of glycerine and water; which renders it more pliable. and swells the emulsion, increasing' the depths of the depressions 22a.

ers |00 and |0| to remove the excess bath liquid and vis conducted over a third rollen |02. As the nlm 20a passes over the roller |02 it receives l a charge |03 of pigment such as oil engraving ink'from a feeder |04. A resilient wiper |00 spreads the ink evenly into the depressions 22a and removes it from the upper surface ofthe film, the dampness of the nlm surface preventing'the oily ink from adhering thereto so that the only remaining ink is that mechanically retained in the depressions: 'I'he nlmis then drawn between two rollers |00 and |00 which press-it into` intimate contact with a second strip ||0 which may be of 'paper or `the like or may .be a second nlm having a surface adapted to reroller |09 serve to drive the nlm and'receiving strip and to keepthem in proper registry, the vrollerf |00 having socketslll. As the nlm 20a and stripv ||0 pass'between' the rollers. the lea'ves the depressions 22a andadheres to the strip l0 in raised portions H0, producing a pattern on 'the strip. which is a reversed duplicate of that impressedon the original negative i'llln;y If

ink of adequate hardness is used', after drying the newly produced duplicate record may be used to'actuate the sensing device, Figure-1, in the manner already'descrlbed. By the above method any desired number -of records may be made on cheap material such as paper, the nlm 20a.

any other suitable. material may be employed in the manner described.

vIt will be obvious to those skilled in the art i that the method and apparatus vdescribed in connection with diagrammatic Figure 9 may also be used to reproduce other than tabulation data,

for example, printed matter'and the like photographed on microfilm.l For direct reproduction- Avfor instance of printed matter in its original values, i. e., black letters on white background or The `data to be reproduced is photographed on the lm by any suitable means.

The film is developed, fixed, hardened and washed normally. In the case of material to be printed in the re, verse tone relation, a Positive film printis made directly from theoriginal negative, and this positive film is also-developed, `fixed,.hardened and -washed in the usual manner.

e 'Ihe positive is then bleached and tanned during which process 'the exposed portions of the emulsion recede, leaving the unexposed portions protruding above the general film level with surfaces' adapted to Iretain certain wet inks.

For ink printing the film may be used at once before drying or if stored in dried condition may Ibe redampened for flexibility and additional elevation of the unexposed portions as previously set forth. Referring to diagrammatic Figure( l1. which shows "a process suitable. for use when printing is to be done on opaque media such as paper, the positive film I|4 is first passed under a suitable ink roller IIB which deposits ink of a character adapted to adhere tothe upraised portions ||6. The film is. then passed between' a pressure roller and a transfer or offset roller I I9, preferably of rubber or the like. The wet ink is transferred from'the portions I I6 to the surface of roller I8, The receiving strip I 9 is passed between the surface of oiset roller ||8 vand a second pressure roller |20, by which process the ink image is retransferred from the offset roller ||8 to the surface of strip ||9 in proper relation for direct viewing. The rollerA ||9 is l continuously cleansed of ink in a bath |2| of suitable highly volatile solvent such as carbontetrachloride. A resilient' scraper |22 removes ,f excess solvent, and the highly volatile character of the solvent causes the latter to evaporate completelyirom the roller surface prior to the next application of ink. If desired, in order to increase the speed of operation of the apparatus, an air blast furnished by a blower |23 through a: nozzle |20 may be employed to assist rapid evaporation.

described, thereby impressing the one color partial image on the moving strip |29. The latter then may pass through an electric oven |34 providing a mild heat to dry the ilrst application of ink. The second and third color partial images are successively superimposed on the first partial images in the same manner as described; sprocketed rollers |09a and |0927 and registering tellers |08a and |0|lb being initially brought into engagement with the various films in proper relation toprovide continuously accurate regis- Second and third ovens |34a and |34b. serve to dry thepink impressions from lms |3I and |32 in the manner described. \To cool the strip |29 after each drying'and thus promote rapid operation, the strip may be conducted through laterally slotted air conduits |35,` |35a and |35b supplied with air blast by a suitable blower |36. If desired, the ink may be only partially dried inthe ovens and drying may be completed by the air blasts, this procedure permitting the use -of lmilder heat in the ovens. i

.It will be seen that the foregoing process, using surface application of inks, for transfer, makes possible the production of color films simply,

rapidly and'wlth a minimum of transfer operations.-4 The stock comprising the receiving strip I may be of various low costmaterials, the principal requirements being a surface capable of ref ceiving the inks and suilicl'ent body to retain its accuracy in productionand in the use Ato which it` is to be put after completion.

While the foregoing process has been described as operating with three colors, it is obvious that it may be` applied to any ynumber of colors of which partial images may be made. In connection with lall varieties of the Aprocess described,

lmay b e washed in any suitable ink solvent.

It will be apparent from the -foregoing that ,the invention makes possible substantially continuous reproduction by printing from strip or ribbon-like supports or carriers having ink carrylng patterns or members arranged in nonplication oi' the invention tomult-color printing',

the process being particularly adapted to rapid 4und cheap production of natural color motion picture film. Referring to Figure'iZ, the nurepetitive succession, and that this process may have a wide variety of applications in addition to the examples described.
