To all whom t may concern:

Be it known that I, WRIGHT D. BREsEE, a citizen of the United States, residing at Los Angeles, in the countybf Los Angeles and State of California, have inventedy a certain j =1ng and carries a roll-5 of sensitized paper,

new and usefull Copying Apparatus, of which'the following; is a speciiication.

My 'invention relates to a duplicating apparatus and particularly 4to a photographic copyingmachine.

An object of thisinvention is to provide a device by means of which absolutely accurate reproductions of any. record may be made, and developed in the same machine 'without the necessity of manually transferring the exposed sensitized sheet from onelthe .plate y12 is mounted upon a metallic vmember 13, seen'more clearlyin- Fig. 5.

bathto another. l t

Another obj ect of this invention 1s to prol Vide in combination with a-device of this typea mechanism for securingthe paper during the'development thereof and for releasin the paperafter development to cause it to all in the proper fixing bat-h.

Finally a further object of this invention is to provide av proper and effectual cutting means for the paper after it has been unrolled the desired distance from thereel;

These and otherv objects are accomplished by the apparat-us' shown in the accompanyin drawing, in which- Figure 1 is a side elevation showing the photographic bellows carrying the lens; the roll of sensitized pa er is shown in dotted li'nes, as is also the eveloping reel and the clamp for'theend'of the paper; Fig. 2 is a plan view partly in section showing the developing reel, the clamping arrangement for the end of the paper, and the mechanism for actuating the clamping arrangement; Fig. 3 is aside elevationof said developing reel ;v Fig. 4 is a plan detail, showing the finger bar release for the paper after completion of development; Fig. 5 is a vertical section on lines XI5 X5 Fig. 6, showing the cutter and the tension means for maintaining contact of the knife with the cutting table, and Fig. 6 is a 'plan View showing the cutter and the -member 13 is held 'normally in l ftween said guide strips 16 and 1 -by'hlelical springs 18 the ends of which are secured to tension means, also the handle forAk operating the cutter.

The apparatus consists of the photo-` graphic casing 1, fitted with bellows 2 `and a lens 3.. A reel 4:' is journaledf in said casthe end of which is arranged to be caught ibetween two rollers6 and 7. -The roller 6 is provided with a pinion 8,'shown yin dotted lines with which a pinion 9, connected lwith ja crankl l0, meshes. .By turning thecrank l=10 the paper, which has been inserted between the rollers 6 an iwoundfrom lthe reel 4.-. The paperis guided fin its descent' by twoplates l1 and-'12, the

plate 11 being lsecured in the casing, Vwhile This member 13A rests on a shelf 14, in the casing and .is provided with a vtongue 15,

vwhich extends between two guide stripsl and 17. The said tongue 15 of said .metallic osition bethe rear of said metallic member, and to .stationary blocks 19 respectively, secured upon the shelf .14. The ends of the tongue f 15 of said metallic strip 13l are inclined .as seen at 20, -for t-he purpose of relieving the pressure of the tongue 15 against a rotary cutter 21 and to prevent dullin the edge. T his lrotary cutter 21 isjourna-le in the end- -of a shank 22 which is provided on the out- Side of the Casin 1, with a handle 23 by means of which 1t maybe withdrawn and .in so withdrawing cut oli vthe paper be'-v 'tween--it and' the tongue 15. Thepsha'nk 22 bears aga-inst" two rigid .strips '24A and "25. Thus when the cutter 21 is withdrawn, it

rides over the inclines 20 and tends to press away the tonguel of the metallic strip; in,

this mannera constant tension is maintained and the cutting of the paper is quick and clean.

When the crank 10 is turned the paper travels downwardly behind the slide 26, and

Aemerges at the bottom, settling, eventually in the recess 27 of a developing drum 28 which is journaled in the bottom of the casing. At that time the drum is in the position substantially as shown in dotted lines, Fig. l, and the paper having entered the recess 27 is clamped by the mechanism presently to be described. lln the recess 27 of' spring 32 -fastened to the drum. Keyed onI the axle 33 of the drum is a crank 34. @n said axle is also loosely mounted a crank 35 connected by pins 36 with the hub 37 of a finger 38 that extends normally behind said lever 29. A ratchet 39 is fixed on said crank 35, while on the crank 34 is pivoted a spring actuated pawl l0 normally engaging the ratchet 39. rlhus when the loose crank 35 is moved about its axis the nger 38 moves the lever 29 which in turn moves the clamp bar 30 and clamps the end of the paper. After the exposure has been made the knife is withdrawn and the paper sheared oft. Thereupon the drum is revolved by the crank 34, winding the paper around the same and in the developing solution inthe tray 41. The pawl 40 is then disengaged from the ratchet 39, whereby the lever 29, returning under the tension of the spring 32 to normal position, withdraws the clamp bar 30 and releases the end of the paper. Such release occurs when the crank 34 has been revolved to the lock 4t2. When the paper has been left in the developer sufficiently long the drum is revolved in the opposite direction, causing the finger bar 43, the fingers of which n'ormally lie in the grooves 44 provided in the drum', to slip under the edge of the paper and disengage it from the drum.y The paper thereupon drops into the tank 45 containing the fixing solution and is. then removed therefrom for mounting. y

What l claim is- 1. rllhe combination with a photographic casing having a developing tank, ofa roll of sensitized paper journaled in the upper part of said casing, means tc operate said vroll to unwind the paper therefrom and cause the same to travel to said developing tank, said casing being provided with a yielding cutting surface, a rotary cutter arranged to operate against said surface to shear 0H' said paper, a drum in said. developing tank, means on said drum to clamp the end of said paper, a crank to control said clamping' means, a crank to revolve said drum, and means to lock said clamp controlling crank on said revolving crank.
