Serial No. 622,411;

To all whom 2'25 may concern:

Be it known that. l, ALLIWER Burro): SEA.- HORNE, :1 subject of the King of Great Britain null Ireland and residing at 3 College Court, Ilnnnnersuiith in the county of London, .l higlunil, have invented a certain new and useful linproiwl Menus for Cleaning Kinenmtogrz.ph :unl Like Films, of which the following is a specification, reference lug haul therein to the accompanying drawing.

This invei'ition relates to an improvol means for cleaning l inemutograph and like films.

It is found in practice that such. films after continued use becomes so (lirty as seriously to nnlr the projecteil hunger clue doubtless to small quantities of lulnncutlng oil from the mechanism of the projecting: ztppzn-utus being deposited on the filn'i. during its pitssuge therethrough and to the minute gt-zirticles 0t tlu and other matter settl' being retained on the film. Such fillll: hitherto been cleaned by hand by s n-culling th'em flat on a table and vigorously rubbing ezichside nlterinitely with u. mixture. of methylated spirit and water; such cleaning process besides being :i tedious one 1e l shortened the iii: of the films. 1.! to the present entiov only readily 21ml expeditiously cleane that in more effect .1, lllzUlZlBl' than etofore but it is ioun i that the actually benefit. by the (leaning i they are rendered more supple and liuhlc lo lire k or tear in subsequent use.

The present invention comprises ease tiully machir for inoistcuiug one or both FlllC or sides of the film w th suitable grouse solvent such as licn'iio anal subsequently wiping or ruhhiu t l l i lie surface or surfaces so treated luring the passage oi. ti lilin through soul 311;.cl1ine whiei'i cm u plurality of. rollers or drums prolon- I I "s i ilt-loll x 1" \f n() oiling-u. 1.1 i it. tension m to faces of the lilin cquul.

over the other so as to contort both shins of the film. These rollers are. covereiiiwith an absorbent material which is kept moistened with henzolin or like grease solvent having no deleterious ellect. on the material of which the film is compesetl. A convem ient means for keepingthe coverings of said rollers fed i Mi solvent is by capillarit yi In the construction illustrated the rollers a a are placed in contact with Wicks (L a which dip into a reservoir a" containing the grease solvent. The film then passes between a pair of rollers a one of which is an i iier roller Z) the others is driven at; a high speed in o contrary direction to the travel. of the film mill is covered with a suitable material and is here-after referred. to as 81 brush roller. The film then passes upward between another pair of idlerand hrnsh rollers (Z 6 alternatelv arranger? tho? 1 to my the ln'usii roller clriven speed the first brush rollers some direction as the film is it in the that acted on by the first brush roller 6.

The film is then led over one or more pairs prefeii'uhly two as illustrziteil-of idle and the The teeth on the roller 5 are not wholly eiictl on to draw the film through the meratio w l i ct-lion us lei ieir respective a convenient uce untier e between some speed as.

The brush rollers 0 (Z and g h are geared together as shown so as to rotate in their respective directions and are driven at a high rate of speed preferably from an electric motor In some cases the rollers a a may be immersed in the reservoir 0, so as to cause the film to travel through a bath of the liquid employed.

-What I claim as my invention, and desire to secure by Letters Patent is 1. In a machine for cleaning films, the combination, with a supporting frame, of moistening devices arranged to bear against both sides of the film, a pair of cleaning rolljeurnaled in the frame, an adjustable support secured to the frame and arranged. between the pair of cleaning rollers, idler rolls carried by the said support and adapted to press the opposite sides of the film against the respective cleaning rollers, and driving devices for drawing the film between the said cleaning rollers and idler rolls.

2. In a machine for cleaning films, the combination, with a supporting frame, of moistening devices arranged to bear against both sides of the film, a pair of cleaning rollers journaled in the frame, an adjustable arm or lever having its middle part pivoted to the frame between the said cleaning rollers, idler rolls journaled at the end portions of the said arm or lev and adapted to press the opposite sides of the film against the respective cleaning rollers, and driving devices for drawing the film between the said cleaning rollers and idler rolls.

In testimony whereof I have signed my name in the presence of two subscribing witncsses.
