METHOD AND APPARATUS FOR PHOTOGRAP- HING.

Specification of Letters Patent.

Application filed June 21, 1911. Serial No. 634,585.

To all whom it may concern Be it known that I, IIENRY I'l. Ciumss, a citizen of the United States ol? America, 1"- siiling in the city of New York and State of New York. have invented an Improved Method and Apparatus for Photographing, of u hich the following is a specification.

The principal object of my invention is to photograph objects by as simple a. method and apparatus as possible, and specially to photograph the appearance of surfaces, such as writing, printing, designs and pictures.

My invention consists in'the method and apparatus herein described and set forth in the claims.

The accompanying drawing illustrates an embodiment of my apparatus by which'n y improved method. may be carried out, 111 whichi Figure 1.is. a transverse section on the line .-\A of Fig. 3, 2 an end view, Fig. 3 a longitudinal centralsection on the line J--l3 of Pig. 1, butwithfone ofthe'reels removed, and Fig. 4: a detail.

Similar characters represent all the figures. p

l an oblong; ca-singyorbox preferably of light sheetmetal, [such f asj almninunn like parts in This casing is entirely" closed"*eXceptlffor. narrow .slot or opening 2 at-its bottom .extending longitudmally fromendg-to end of.

the casing. p

Elisa lamp supported withinthe casing l above the opening 2, and preferably extending about the lengthof said opening.

Said lamp may he an incandescent electric lamp, such asshown in tbedrawings, or any other lamp producing a bright light.

,-l. is'a reflector in the form of a casing, surrounding the top and sides of the lamp 3, and having its sides at .the bottom conlraeted and terminating near the edges of the opening 2, but leaving a narrow ion-- gritudinal space or slit 5 between said edges a nd sides through which a-strip of sensitized paper or film may pass without friction, but so as to practically prevent. the admission of light to the interior of the casing 1 from the outside. The ends.6 of the reflector casing at slope upwardly and inwardly so as to assist the top and sides of the reflector lin deflecting the light from the lamp through i the opening 2. The inner surfacesof the re tlecror 4 6 should be of highly light re- 1 Patented May 19.1914.

i 7 is an oblong plate of clear transparent glass or similar material closing the open bottom of the reflector t. .I have shown in i the drawings this plate 7 with a downwardly extending flange or tenon 7 to either side of which the bottom of the reflector edges are turned, so as to hold said plate in place.

8 1s a strip of transparent or translucent sensitized material on which the photograph is to be taken. This strip is wound upon a reel 9 journaled inside the casing 1.

10 is a reel wound with a strip of opaque paper or similar material 11, said reel being journaled in the casing l in a similar manner to the reel 9. 12 is a take-up. reel also ournaled in the casip 1 and which is adapted to wind up thestnpS after the exposure of the same and also towind with it the. j:

opaque strip, 11. from the reel 10, to prevent,-

undue exposureto the. sensitized strip after the photograplrhas been taken on it. The p reel l2 is .causedto automatically wind up the strips 8 and 11 bythe uncoiling of a previously coiled spring, as willhereinafter be described.

1 13- are two sets of'guide plat-es arranged i on either side of .the *reflector l and between it and the .bottom of the casing .1, and preferably sons to cover "the .strip 4. fromthe opening2 tosome distance, above said opening- These guides shouldalso be curved and arranged as to have no edges orv corners against which. the strip. 8 could rub.

They may also, in order to protect the strip 8 from the light, be provided with black or light absorbing surfaces.

The delivery reel 9 bearing the. non-exposed sensitized strip isseparated from the take-up reel. 12 by a longitudinal partition 1% dividing the casing 1 into two compa-rtments. The surfaces of-this partition 14 are preferably coated black or are light absorbing. The strip 8 should. be. fed down between the nearest set of guide plates 13,- .through the nearest slit 5, under the glass.

plate 7, up through the next slit 5, and between the second set of guide plates 13 to the take-up roller 12, to. whichthe opaque strip 11 should also be fed. The long-opposite sides of the slot or opening 2. at the bot* tom of the casing 1 are formed of the lower edges of two oppositely sloping sides 1 5.

This construction provides not only that the plate 7 or what is under it may be the only contact surface of the apparatus with the surface to be photographed, but that all the rest of the surface to be photographed that is not covered by the plate 7, can be seen.

The take up reel has a round socket 16 at the center of one end, and a post 17 angular in cross-section extending from the center of the other end. A round pin 18 passes loosely through one end 19 of the easmg 1 and is supported in bearings 20 on the outside of said casing. This pin 18 is provided with a transverse projection or pin 21 and a coil spring 22 surrounding the pin 18 and bearing upon the cross pin 21 tends to bear said rod inward. A ring or other handle 23 attached to the outer end of the rod serves to draw the same outward (against the action of the spring) and away fromthe reel 12.

The winding up mechanism of the reel 12 is the following 24 is a coil spring casing provided with a central circular hub 25' j ournaled in a corresponding hole in the end 26 of the casing l (opposite to the end 19). This hub 25 is provided with an angular socket within which the post 17 may enter and be held. The spring casing 24 is provided with a circular flange 27 having arranged at intervals thereon, recesses 28. with which engages a spring dog or clutch 29. 30 is a post loosely journaled in a circular socket 30 in the casing 24, and in a fixed bearing 31 in front of said casing. 32 is a coil spring surrounding the post 30 Within the casing 24, and which is secured at the inner end to said post, and at the outer end to the surrounding wall of the casing. Secured to the post 30 is a toothed or ratchet wheel 33, and 34 is a pawl or dog loosely pivoted to the'bearing 31 and engaging with the teeth of said wheel. 35 is a handle sccured to the outer end of the post 30, by which the same may be turned to wind up the spring, said Winding causing the teeth of the wheel 33 to ride over the pawl 34, but the pawl (unless raised) preventing the unwinding of the spring from its center. lVhen thedog 29 is in engagement with one of the recesses 28, the spring 32 is prevented from unwinding from the outside, but if 'said dog be'withdrawn from such engage- .ment, the spring Will unwind from the outside, and cause the casing 24 to revolve, as also the reel 12 if its post 17 is within the socket of the hub 25. 36 is the handle by which the apparatus is manipulated for photographing. This handle is ho-llow,as is shown in Fig. 3, and is secured to the top of the casing 1. 37 is a vertically movable rod extending longitudinally within said handle through guide ways 38, and 39. The lower end of rod 37 loosely engages with one arm of a lever 40, the other arm of said lever being connected with an upward eX- tension of the dog 29 by a wire or other flexible connection 41. This connection is inclosed within a tubular casing 42 for the protection of the same. 43 is an electrical terminal secured to the upper surface of the support of guide 3'9, and 44 is the opposite electric terminal above 43, and on the under surface of a block 45 secured to the rod 37. A coil spring 46 between the guide 38 and a knob 47, tends to normally keep the rod 37 raised, and the terminal 44 away from terminal 43. 3 is an incandescent lamp, the outer surface of which is preferably cylindrical, as shown at 48. The lamp extends through the sloping ends 6 of the reflector 4, and is supported in tubular sockets 40 extending inward from the ends of the casing 1. The two line wires 50 and 51 from any source of electric supply are connected spectively with one of the lamp terminals, and with the movable terminal 44, which is operated by the rod 37, and the connecting line 52 to complete the circuit when the two terminals are in contact, connects the other terminal of the lamp 3 with the fixed contact 43 in the handle 36.

Wherever it is possible the surfaces inside the casing 1, and the outside surfaces of the reflector 4, should be black or light absorbing. I have shown the electric lines in the figures diagrammatically, but in practical use they should be inclosed within the handle 36 and easing 1, and they and the terminals should be properly insulated from, other parts and devices. The reels 9 and 10 may be removably journaled in the casing 1 in any well known manner.

If it be desired to photograph a picture, design, or printed page, as for example on the surface of a sheet 53 (see Fig. 1) the spring 32 should be first wound up'as above described, the sensitized strip 8 should be fed between one set of guides 13, under and across the glass 7, up between the other guides 13 to the reel 12, and the opaque strip 11 from the reel 10 should be fed to the reel 12. The apparatus should next be placed with the part of strip 8 that is under the glass 7 resting at the beginning 54 of the printing or: design or printing at the top of the page, with the-glass 7 extending along and over the upper e'nd of the printing or design. There will then be practically no exposure of the strip to any light from outside the apparatus. The knob 47 should then be depressed. This action coinpletcs the electric circuit (by bringing into contact the terminals 43 and 44) and lights the lamp 3, causing a stron light to be projected through the glass ,and sensitized strip 8 to the design or printing, and refiected back upon the strip 8, on which said design or printing will be photographed.

' The depression of the knob 47 will cause the raising of thedog 2%) from one of the recesses 28, and thus release the spring 32, to permit it to rotate the reel 12, if not otherwise prevented. As long as any material pressure remains on any portion of the surface of the strip 8, the spring 32 will not rotate the reel 12. By slowly drawing the device downward with the glass 7 over the printing 01' design in the direction of the arrow (Fig. l), the strip 8 will be gradually drawn off the reel 9 between the glass 7 and surface of 53, and be exposed to the light and said surface photographed thereon, and immediately afterward drawn up and around the reel 12 by the action of the spring 32, which also draws upon said reel the opaque strip 11 to further protect the previously exposed strip 8 from the light. As soon as the pres sure on the knob 47 is released the circuit will be broken, the light of the lamp put out, the dog 29 will be forced into oneof the recesses 28, and the sprin 32 will be held, and there will be no furt ier winding of, the reel 12. The previously exposedstrip can be used if desired from which to print other photographs.

My invention is particularly adapted for copying pictures, designs and printing upon plane surfaces.

It will be evident that my invention is not limited to the precise method above, described and that the apparatus above described may be varied or changed in many respects without departing from the invention.
