Be it known that I, .ALBIN LEssiNe, a citi- VZen of l(ul-ermany, and resident of Jersey City,co`uiity of Hudson7 andState of New Jersey, have invented certainnew and useful Improvements in Photograpinc-Printing Apparatus, of

My invention relates to apparatus for printing photographs and' has for its object to provide an apparatus of Anovel construction adapted for either plate or film print- Aing and which, when used for the latter purpose, does not require vthe film'to be cut into sections. corresponding to `the individual pictures contained therein,prior to the printing thereof. Other f more specific objects of niy`invention willappear from the description hereinafter* and the features of 20.

novelty will be pointed out'in the appended In the accompanying drawings which f show an embodimentv of my invention, withfAs shown in thedrawing 4the apparatus comprises a receptacle or body 10 of suitable material and dimensions and provided with a movable cover 11 whereby access to the in-` teriorof said receptacle may be had.v A cas-` ing.12` extends upwardly from the body 10 and vcommunicates with the interior thereof,

Provisions. may also bc made for the accommodation and positioning of suitable masks 15 in front of 'they light pervious panel 13 to variably define the active area thereof,

Studs 16 and members 17 are mounted in y the casing at its upper end, the members, at

least, being rotatable, and are arrangedv to receive the opposite ends of reels 18 and 19,

the connections preferably being such as to.

Gears 23 are fixed yupon the rotatable members 17 and are operatively connected by means of a pinion 24 located upon a shaft ournalled in saidy casing andr extending exterioily thereof, the projecting end of said shaft being` provided with a key 26 or other device whereby rotation thereofv mayv be manually accomplished. y y

A brush 27 mounted upon a back 28 is contained within the casing 12 in registry latter by means of a spring 29 preferably secured to the back 28 and engaging the rear l wall of said casing 12 as shown 'in Fig. 1.

In the Voperative condition of the apparatus the film 30 which is to be printed passes from the receptacle 10` in which it is contained over a vsuitable guiding device 31 and in back of the light pervious panel 13 and to the reel 18 to which its end is detachably A roll ofssensitized paper 32 on which Vthephoto'graphs are to be Iprinted is rotatably `mounted in the receptacle 10- and passes therefrom over the guidingdevice 31 between the film 30 and the brush 27 to the reel 19 to which its end is detach ably secured in any well known way. By rotatablyac-y tuating thekey 26 the pinion 24C and consequently the gears 23, are rotatedto windvthe film upon the reel 18 and concurrently to Vwin'd the sensitized paper 32iipon the *reel 19 and thusfto bring the first picture upon the' film 30 and'aniactive section of the sensitized paper 32 into registry with the light has been exposed the desircdyperiod of time to complete the printing, the key 26 is again actuated to bring the second picture on the filiii 30 anda new active section of the paper 32 into registry with said panel 13 to print said second picture, this operation being repeated successively until all the pictures upon aA given :film have been exposed and printed. y

During the shifting of the film and sensitized paper, the brush 27 maintains the same under a tension whereby both film and paper are prevented from wrinkling, while during exposure when film and paper are stationary, said brush serves to maintain the paper in firm and even contact with the film and to press both film and paper evenly and,

uniformly against the light pervious panel 13. rihe action of the brush is such that the film and paper will be properly held in position down to and including the last picture, so that all of the pictures on a given film may be exposed without difficulty. After one film has been completely exposed and printed both reels 18 and 19 upon which the film and paper have respectively been wound, may be bodily removed from the apparatus or said paper and film may be 11n-- wound from said reels as desired. The removal of the printed paper, of course, takes place in a dark room and may be followed either immediately or subsequently by such steps as are required to complete the production of the pictures. It will. of course be understood that suitable provision is made to prevent light from reaching the interior of the body 10 where the roll of paper 32 is located and also from reaching that part of the casing 12 in which the reel is positioned.

Prior to the actual printingoperation, a suitable mask 15 may be placed in front of the panel 13 to define the area required for the particular film being exposed and the flanges 2O and 21 may be adjusted to correspond to the width of said film and of the sensitized paper respectively. By selecting` a mask suitable for the purpose or by providing a specially constructed panel 13, the apparatus may be readily adapted for cthciently exposing moving picture films. The apparatus may also be utilized as an ordinary printing frame to print individual pictures and for plate printing by simply placing the individual film or plate with the required sheet of sensitized paper between the panel 13 and brush 27. In order to facilitate the printing of such individual films or plates it is desirable to have the panel 13 in an inclined position, this result being attained either by tilting the entire apparatus or by making provision for tilting the casing 12 relatively to the body 10.

The apparatus is simple in construction and efiicient in operation and does away with the necessity for cutting a film into sections corresponding to the individual pictures thereon, thus not only retaining the film in its original complete condition, but also increasing the output of finished pictures.

Various changes in the specific form shown and described may be made within the scope of the claims without departing from the spirit of my invention.

` I claim:

1. A photographic printing apparatus comprising a body arranged to contain a photographic film and a supply of sensitized paper, an upright casing divided into an upper and a. lower interior chamber and extending upwardly from said body and communicating therewith, an upright light pervious panel in one wall of said casing in registry with the lower chamber thereof, a pair of reels journalledin the upper chamber of said casing and arranged to independently receive said film and paper respectively, gears operatively connected with said reels, a pinion in mesh with said gears, a Vkey for rotating said pinion and gears whereby said reels are actuated to concurrently adjust said film and paper in registry with said panel, a brush located in the lower chamber of said casing and having its bristles in direct surface contact with said paper and a spring whereby said brush is resiliently pressed against said paper to press it and said film into surface contact with each other and with said panel,

2. In aphotographic printing apparatus, the combination of a light pervious Danel, a container for a photographic film and a supply of sensitized paper, means for separately feeding said film and paper to progressively and concurrently adjust them in registry with said panel, a brush having its bristles in direct contact with said paper and a spring whereby said brush is resiliently pressed against said paper to press it vand said iilm into surface Contact with each other and with said panel.

In testimony whereof I have hereunto set my hand.

ALBIN LESSING.
