PHOTOGRAPHIC-PRINTING MACHINE.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed. April 21, 1909. Serial No. 491,249.

To all whom it may concern:

Be it known that I, DAVID HoRsLEY, a citizen of: the United States, and a resident of Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Photographic- Printing Machines, of which the following is a specification.

This invention relates to a photographic printing machine, and its object is the production of such an apparatus in which pontions of a film or sensitized paper or other materials are consecutively exposed to light rays during the operation of printing. In the drawings Figure 1 represents an elevation partly broken away of the invention,-. Fig. '2 shows a partial section of Fig. 1 on

line

2, 2, Fig. 3 is a partial section of Fig.1 on the line 3, 3, Fig. 4 is a right hand side view partly broken away of Fig. 1, Fig. 5 represents a partial enlarged section of Fig. 2 on the

line

5, 5, Fig. 6 shows a partial right hand end view of Fig. 5, Fig. 7 is a section as on the

line

7, 7, of Fig. 1 and Figs. 8 and 9 represent the portions of the reel of the invention separated from each other.

A casing is shown at 20 with the front wall 21 having an opening 22, top 23, bottom 24 and hinged side 25. Dovetailed guides 27 on the bottom 24 adjustably' support the foot 28 of a support 29 for the lamp 30, which latter in the present case is a Nernst lamp, that is provided with electric current by means of the Wires 31. An angle shaped bracket generally designated by the numeral 35 With the

members

36 and 37 extends from the front wall 21 of the casing. The foot 38 of the member 36 contains an opening 39 which registers with the opening 22 of the front wall'21. 47, 48and the

journal bearings

49 and 50 extend from said bracket 35.

In the opening 39. ofthe foot 38 is supported the tube 53, having a slot with the branches 54 and 55 at right angles toleach other. On the tube 53 is telescopically supported the sleeve 56 having fastened to its outer cylindrical surface the ring 57. A' pin 59 extends through the ring 57 andsleeve 56 into the slot having the branches 54 and 55.

Bosses 44, 45, 46,v

ing 50. A

A spring 60 bears between the ring 57 and the foot 38 of the bracket 35. A segmental cylindrical cap 61 is secured to the outer end of the sleeve 56. A slot 62 a d grooves 63 are formed in said cap. A s utter 65 over the opening 22 is fastened to a spindle 66 ex-' tending through the front 21 of the casing,

and the foot 38 of the said bracket 35. An arm 67 extends from the spindle 66 to operate the shutter, and which is accomplished by moving the said arm 67 and thereby allow the light rays to enterthe tube 53.

The journal bearing 49 supports the shaft 70 to which is. fastened the sprocket wheel 71 having the'sprocket pins 72. A spur gear 73 is fastened to the shaft 70 the teeth of which mesh with the teeth of the pinion 7 fastened to a 'spindle 75 in the journal bearing 50, and a collar-76 is fastened to the spindle 75 on the other end of the said bearpulley 77 fastened to the spindle 75 carries a belt 78, which leads to a pulley 79 of an electric motor 80 mounted on the top 23 of the casing. A pin extends from the boss 47 and on it is pivoted the arm 86, which latter carries the pin 87. An idler roller 88, with the two pair of flange rings 89 extending from its cylindrical surface is journaledon thepin 87 -A spring 90 extends from a hook 91 on the arm 86 to a hook 92 on the lower portion of \the front wall 21 of the casing. An idler roller 95 with the end flanges 96 is journaled on a pin 97 extending from the boss 46'. From the boss 48 extends a pin 101 on which latter is supported a guide .plate 98 with the guide -:edge'99 and guide lugs 100 adjacent to the latter.

Apin extends from the' boss 44 on which is journaled a reel 106 for the negative film 107. The said reel comprises the disk 108 which is supported on the sleeve 109 having the inner sleeve 110 connected thereto. A spring clamp 111 with one end fastened to the sleeve 109, encircles the same,

and can be used for securing the end of the film 107 to said reel. A tube 112 is slidably supported in the sleeve 109 and carries the accompanying disk 1130f the reel. A screw 114 in the boss 115 can fasten the tube 112 to the pin 105, and a screw 116 in the boss 117 can fasten the sleeve 110 to the pin 105.

A pin 118 extends from the boss 45 and carries a reel 120 similar to the reel 106 for the unexposed film 121.

To operate the invention, the negative developed film 107 and the unexposed film 121 having been located on their

respective reels

106 and 120 are led against the guide edge 99 and lugs 100 of the guide plate 98, with their gelatinized faces adjacent to each other. The films are then lead under the idler roller 95 over the sprocket wheel 71, the openings of both films being engaged by the sprocket wheel to prevent them moving relatively to each other. The grooves 63' in the cap 61 constitute clearance spaces for the pins 72 of the sprocket wheel 71. The idler roller 88 at the same time bears on the films to maintain their faces closely together. To engage the films with the said sprocket wheel 71 the sleeve 56 is moved away from said sprocket wheel so that the pin 59 is engaged by the branch 55 of the slot in the tube 53. After the films are in place the pin 59 is released from said branch 55, and the tension of the spring 60 causes the cap 61 to force the films against the surface of the sprocket wheel 71. .The lamp 30 and motor 80 are now operated and the shutter 65 opened. The light rays pass through the tube 53 on their Way through the slot 62, to the films and print the unexposed film while it is turning with the negative film over the sprocket wheel 71. Displacements of the films with respect to each other during the operation of printing are thus avoided.

Sensitize'd photographic paper may besubstituted for the unexposed film for printing the copy or positive.

The invention can also be used for making a negative from a developed positive, which may be accomplished by locating the developed film or positive next adjacent to the light rays in the manner described for printing the positives, and then printing said negatives from their accompanying positives. It is also evident that a cylindrical surface or a plane surface might be sub stituted for the sprocket Wheel, and that portions of the printing material, films, paper and the like might be consecutively carried,

by said surfaces and exposed to the light ra s.
