QUID SUBSTANCE DEVICE FOR PERIODIC DI STRIBUTION OF A LI ON A PLANE SURFACE, CINEMATOGRAPHIC FILMS 0R OTHERS Filed May 31, 1930 Patented Dec. 27, 1932 l UNITED STATES PATENT OFFICE an ARMAND 30mm, OF rams, FRANCE DEVICE FOR THE rnnronrc nrs'rnrimrrolvor A LIQUI sunsrnivo'r'i ON A PLANE SURFACE,- omnMAToGRAr rc FILMS on: cranks This invention refers to a device for the periodic distribution at regular intervals and in a neat and proper manner of a liquid substance on a plane surface, such as cinematographic films, metal bands, tissue or other material.

The device is essentially characterized by a kind of line drawing pen with suitable sized blades, working in the contrary direction to the drawers pen, and which is made up of a rigid blade and a movable blade adjustable in relation to the preceding one, and the width of which is sized according to the surfaces to be covered. 7 For the driving of this drawing pen device,

a machine is provided which is characterized in that all the organs taking a part in the operation of the drawing pen, inking, motion, lifting up, &c are positioned on a member moved in an alternating rectilineal direction. and the drawing pen is running in a direc tion perpendicular to the motion forward of the band to be partially covered with the said v substance.

This substance consists for the cinematographic films, for instance, in a tinge to be affixed on each image for the colouration of the film in view of its coloured projection.

The product in question also maybe a varnish, a stiffening, an emulsion, vor similar.

In the case of a film tintage, each variety of colour is preferently requiring a proper driving mechanism with its inking, or the ma 7 chine may be built wide enough so as to drive simultaneously a plurality of drawing pens.

In the accompanying drawing:

Fig. 1 shows 4 positions of the drawing pen while using same.

the drawing pen.

In reference to the drawing, a kind of line drawing pen working in the contrary direction to the drawers pens, consists in two a blades A, B fastened one to the other by a Application filed May 31, 1930, Serial No. 458,581, and in Belgium June 8', 1929; g

under the drawing pen-starting for a new op;

. Fig. 5 shows both front and sidevie'ws of means of a rivet G. The blade Aiis rigid, the blade B has a certain flexibility, and botlr blades are made up of metals unaffected by the substances to be used. The blade B can be more or less removed fromtheblade' A- by 819 means of a screw D or a small cam, and it is shorter thanthe said blade A, so'that there quired slope obtained while the machine is running brings the both ends of the blades seating on the same horizontal plane." The blade width is sized ac cordingto the surface to be covered.

This special drawing pen is moved bysome mechanical devices to be described hereafter 7 along a way bringing sameto' a tank where it is filled with colour, then carried on the sur face to be covered with the tinge, returned back over the said surface without coming in touch with same, and brought again to the inkingtank for a new operating cycle. I '1 During this operation, the coveredband is auton'iatically fed of the proper length so as to bring another surface tobe covered eration. I 7

Theslope of the drawing pen is m'ad e ad j ustable through the height between same and its impact point and by the position of the way in relation to the surface to be covered, Fig. 1 shows first the position'beforethe impact with the surface to be covered, secondly the position after the impact and before the settling of the liquid, thirdly the position during the settling, and at last the position when the operation is performed.

It is convenient to have the rod A charged with a movable weightrunning along the same, or provided with a spring in-order to adjust the impact strength when the drawing pen comesin touch with the surface, thus avoiding the phenomenon of the chattering or skipping of the pen.

Also the tank maybe disposed so as to accompany the drawing pen and to supply same periodically with the liquid, or placed steadily at the end-of its stroke and maintained with a constant level of liquid.-

The driving device may be for instance built. inthe following manner as in the case 100 of the tinting of the image field for trichromic films.

Starting from the pellicle 1, the windlng ofi direction is shown by the arrow, this pelsion by a pressure roll 2. A spindle 3 is pro-- vided atea-ch end with an eccentric plate 4 driving respectively a connecting rod 5 attached to a sliding frame 6'held and guided by the slides 7, Fig. 2, directly connected to the base plates, Fig.2, by columns. On the reciprocatingsliding frame 6 are mounted all the necessary controlling means forthe tintage and further operation. A connecting rod 9 driving the pen holder-10 followsthe reciprocating stroke of the frame 6, the stroke being so measured that the'drawing pen 11 at the end of its stroke releases the film it has just covered With colour, whereas at the beginning of the stroke it is in apositionto take colour in a tankwith a constant level 12, Fig. 3. Thedirection of the drawing pen is secured by the tilting support 13 held in a slanting positionby a spring 14.

A small bar 15 sliding into two bearings 16 and ,17 .is bent at one of its ends in order to bring back to the horizontal position the tilting support now in the tintag e position. An, arm 18 driven bythe frame 6 is engaged into a groove 15 of the member 15. Thesaid groove is less long than the stroke of thearm 18,:-so that when this last comesinto touch with the bottom of the groove, its member 15 is carried along] Themember 15 being continually in. touch with the tilting support by means of the roller arm 19, the support 13 will run-salong the curve of the bar 15 and takes the neededihorizontal position for the tintage. T r V As soon as thedrawing pen is leaving the film, .the'motion forward of the frame 6 brings thearm 18 incontact with the other end of the groove in the member'15, bringing thus the curved part ofthe'member under the roller 19 and tilting the support 13.-

As the stroke is coming now at its end, the back motion of the frame 6 carries the drawing pen' along an inclined plane towards the inking tank. Then the pen having taken liquid leaves the tank'at the end of the stroke owing to the reverse motion of the member 15 impelling thejtilting support 13 to come back to the horizontal position.

An image field'being tinged, it is necessary to removethe possible excess of colour, and therefore after a revolution of the driving drum' 20 carrying forward the band to be covered for the length corresponding to three images, a drying pad 21,- Fig. 4, driven from'the frame 6"through 'a' small bar 22 7 runs slightly on the coloured part of the the film is fed withthe images (in the case of the trichromic films) it must go successively through two other machines in order to receive two further colours, or come again in the same machine, after having substituted the previous drawing pen with another pen for the application of another tinge.

Having now described the'object of this invention and in which manner same is to be performed, what I claim is 1. Apparatus forperiodically distributing a liquid substance on I a film, comprising means for moving the film in a right line, a member mounted for reciprocating movement at an angle to the film, means to impart reciprocating movement to said member, a fount, a tiltable member extending across and above the film and under theinner end of which said fount is located, a holder slidably mounted on said tilta-ble member, a liquid applying instrument pivotally connected to said holder and depending therefrom, a connecting rod between the holder and the reciprocating member, and means to alternately move, the tiltable member to substan tially horizontal position and at the instroke of the holder to tilt said tiltable member so that its inner end lowers said instrument into the fount. I I

2. Apparatus as claimed in claim 1, in-

cluding'a pad carried by the reciprocating member and arranged to pass transversely across and on the upper side of the film.

8. Apparatus as claimed in claim 1, in-

cluding a pad carried byth'e reciprocating member andarranged to pass transversely across and onthe upper side of thefilm and also including a drying pad, so arranged as to be transversely crossed on its upper side by the pad which is carried. by the reciproeating. member and means to impart step by step rotation to said drying pad.

4. Apparatus as claimed in claim 1,; in which the means for tilting the tiltable member comprises a spring active to tilt the same, a tappet on said tiltable member, a reciproeating rod having 'a cam arm cooperating with said tappet and an arm carriedby said reciprocating member and travelling between spaced stops with which the reciprocating rod isprovided. w
