Monroe and State of New York, haveinvented certain new and useful Improvements in Photographic and Developing Apparatus, of which the following is a specification.

This invention relates to photographic, Y

printing and developing apparatus having the combined functions of exposing the film to the action of light and of thereafter treating the same, the said apparatus being here shown as motormeans actuated by the mechanism for controlling the motor.

An object of this invention is to produce a photographic and developing apparatus in operative relation to each other, the said developing apparatus having a receptacle for fluid, which fluid. will act on the coated surface of the film and with relation to which a rotary member, preferably in the form of a drum, is supported and adapted to displace the fluid to such an extent as to make it possible to employ a minimum quantity of fluid for the purpose of immersing the film, means being also provided for delivering film to the receptacle and for removing it therefrom.

.It is furthermore an object of this invention to provide a receptacle in operative re lation .to the means for removing the film from the first mentioned receptacle, the second mentioned receptacle being adapted to contain liquid preferably of the character of fixing fluid. In order to cause the film to enter the second mentioned receptacle and to lie flat therein after it has been released by the means for removing the belt from the first mentioned receptacle, I supply the second mentioned receptacle with a spraying attachment designed to force liquid and I utilize the force of such liquid to cause the film to travel in the second mentioned receptacle while, at the same time, acting on said film to cause it to lie fiat in the liquid contained in the second mentioned receptacle, and furthermore an object of the invention is to provide mechanism for spreading the film and mechanism for immersing the film. A still further-object of this invention is to provide a motor for driving the appara- Speciflcation of Letters Patent;

tus-and' means actuated b a part of the v apparatus for. controlling t e motor. Furthermore, .an object of this invention is to provide a conveyor or carrying device preferably comprising an apron or belt with which a flexible device such as a chain or the like coacts to retain the film on an apron or belt while the said film is being subjected to the action of developing .or other fluid. 1 W1th the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification,

wherein like characters denote corresponding parts in the several views, in which- Figure 1 illustrates-a view in side elevation of a photographic and developing apparatus embodying the invention; Fig; 2 illustrates a' view inelevation of a part of the interior mechanism; Fig. 3 illustrates an elevation of the interior mechanism from theopposite side; Fig. l'illllStlfltGS a portion of the apparatus partly in section; [Fig 5 illustrates a view in elevation showing the end of the apparatus, a partthereof being in section; Fig. '6 illustrates a detail plan of the rear of the apparatus; Fig. 7 illustrates a side elevation of a portion of the rear ofthe apparatus; Fig. 8 illustrates a detail plan view of they pump and sprinkler;

Fig. 9 illustrates a detail view of a power transmitting mechanism; Fig. 10 illustrates a perspective view of a film immersing frame; Fig. 11' illustrates a modification with the spraying attachment applied to a hand operated machine; and Fig. 12- illustrates a detail of the tripping mechanism.

In these drawings A indicates a casing for the developing apparatus covered by a magazine B, adapted to contain a supply of film here illustrated as in the form of a roll B. The side of the magazine has an exposing chamber A and a camera D is applied to the side of the magazine for exposing the film in the exposing chamber to light.

The magazine is provided with appropriate brackets such as A appearing in Fig. 1 for supporting the roll B, the film from which is run over theiidler A, into the exposing chamber AF, where it is in position to be acted on by light admitted through the camera D. The magazine is preferably above the casing A and acts as a cover for said casing. The front a of the casing is stationary with relation to the base a, whereas the sides and back are connected to the magazine and the back is hinged to the base, thus allowing the sides and back of the easing to be swung rearwardly with the magazine for the purpose of permitting access to the interior of the apparatus.

The rear of the casing has an opening a and below the opening brackets a are attached to the casing. A pan or receptacle a is supported by the bracket a and said pan projects into the casing through the opening (L The purpose of the receptacle a is to contain a fixing fluid into which de veloped films are delivered. Under ordinary conditions the light would not be sufficiently strong to affect a developed print coming from the developing apparatus (to be hereinafter described) but for the purpose of providing a safe-guard against action of light on a developed print, a hood cp -is removably secured to the casing in any appropriate manner. I

The casing contains a tank or receptacle E adapted to receive developing fluid and said tank may have ends a, in which the shafts F and G are journaled or said shafts may be suitably journaled in operative rela: tion to the receptacle.

The receptacle may be supported by the plates H secured to the base and said receptacle has a drain pipe I to which the cock J is connected, said cock extending through the side of the casing. A drip pan K is located under the receptacle and is provided with a drain nipple 7c, extending through the base. The drip pan is provided to collect the drippings from the .chains, conveyers and rollers,;to be presently described. Shafts is extend between the plates H and support the pan K by passing through apertures in its sides and said shafts carry pulleys overwhich chains travel. The shaft F has an extension passing through the side of the casing on which is mounted a stub shaft 20 (Figs. 5 and 9) and said stub shaft is provided with a sleeve 21 supplied with a shoulder 22 at one end and has its opposite ends screw threaded as shown at 23. The sleeve is further provided with a longitudinally disposed groove 24:. The sleeve is anchored on the stub shaft at any position desired through the medium of a .set screw 25. A worm Wheel 26 has its hub rotatable on the sleeve and said worm Twheel has its side recessed to form a clutch member as shown at- 27, the said worm wheel being engaged by a worm 28, mounted on the shaft 29 of the motor 30, the said motor being here shown as an electrically driven type, although I do not wish to be limited with respect to the style of motor employed.

to prevent rotation of the clutch member 31 on the sleeve. In other words, the oflice'of the clutch member 31 is to communicate motion ofthe worm wheel 26 to the sleeve and as the sleeve in turn is coupled to the stub shaft it follows that the stub shaft will be rotated and as the stub shaft is connected to the shaft F, power is communicated to the mechanism for feeding and conveying the film, A spring 34 encircles a portion of the sleeve and has one end bearing against the clutch member 31 whereas the opposite end of the spring 34: bears against the nut 35 which engages the threads 23 on the sleeve. By means of this nut, tension of thespring 34C is controlled.

Endsof the shafts F and G have sprocket wheels f and g', respectively; and said sprocket wheels are connected by a sprocket chain M, by which motion of the shaft F is communicated to the shaft G, and the. shaft G also has a pinion G meshing with a gear wheel Gr' for driving the roller A frame N is removably supported above the receptacle and said frame has a ependthe rotatable drum 0. The drum may be hollow and is preferably comparatively large with respect to the receptacle in which it is supported for, by this construction. the developing fluid contained in the receptw-le is displaced and a small quantity of the veloping fluid will be sufiicient to completely immerse a film as it is carried by the drum. One end of this drum is provided with a pcripheral gear P, meshing with a pinion Q, rotatable on a stud projecting from one of the.arms. The pinion Q, is driven by a gear wheel R on a shaft S, the said gear wheel R taking motion from a gear Wheel R, mounted on the shaft G.

The end of the drum opposite the peripheral gear P is recessed to form a shoulder T and said shoulder is engaged by a dog U,

which is slidably mounted on a stud V, the

said dog being pulled downwardly by the spring '1). Under ordinary conditions, the weight of the dog will be sufiicient to cause it to move longitudinally, but in order to mg arm n at each end forming supportsfor gages said switch. That is to say, when the dog is elevated through its engagement with the drum, the upper end of the said dog engages the switch and opens it, thereby cutting out current to the motor but on the de- 7 scent of the dog U and its disengagement with the switch, the spring of the switch operates to cause an engagement of the contacts of the switch, thereby completing. circuit through the switch to the motor.

As shown in the drawings, the conductor conduit 37 extends inside of the case and the

conductors

38 and 39 extend 'therethrough and project from the coupling 40 tothe terminals of the switch.

41 is a conductor which may be connected to any source of electricalsupply and it extends through the insulating box 42 to the conduit 37 the wires from the switch to the motor being extended through the conduit 43 and through the box 42. In fact, any appropriate wiring may be employed for connecting a motor to the source of electrical supply through which a switch or cutout operatedbv mechanism is employed in connection with the apparatus.

The mechanism is brought to rest at such time as the print is immersed in the developing fluid contained in the tank and the mechanism cannot betoperated until the dog U is moved out of engagement with the shoulder T. This is accomplished by the lever W which is journaled in the casing and has an arm. W bearing against a stud W on the dog. Pressure on the outer end of the lever results in pressure on the upper *end of the dog which will cause the lower -end of the dog to swing out of engagement with the shoulder. When the lowerend of the dog is clear of the shoulder T, it is free to drop so that its end clears the shoulder T of the drum. The switch will be closed to conduct current to the motor for the pur-' pose of starting the motor as heretofore indicated. The periphery of the drum being cut away, as explained, also permits the arm X to be moved with relation to the dog w on the feeding and cutting roller to be hereinafter referred to.

The arm X is held normally depressed by means of the spring a and when the drum rotates sufliciently to bring the recessed portion thereof under the arm X, the said arm is depressed until its upper end clears the Y end of the dog w. When the dog is released,

the spring forces its nose into engagement with the ratchet wheel Y on the shaft 3 and hence rotation of the shaft is communicated to the feeding roller Z, it being understood that the dog w is pivoted on the feeding roller and that the spring w holds the nose ratchet wheel Y.

' For the purpose of holding-the arm;X;

normally elevated a cam Z'- is mounted on the frame N and may be moved to hold the of the dog normally engagement with the I arm normally elevated in which position the said arm will hold the dog out of engagement with the ratchet wheel and the shaft y. maybe rotated without. operating the-feeding roller.

When the print is caused to travel between the feeding roller Z and the rollers e, it is punctured at each rotation ofv the feeding roller by the serrated blade Z on the feeding roller, and the print is then directed betweenthe two rollers z and 2 and from' there to the interior of the developing apparatus where the print is delivered to the conveyer consisting of a chain S and the belt S In operation when the parts are in the position shown in Fig. 4, the cam Z is moved to disengage the arm X and the lever W, pressed. tomove the end of the dog U out of engagement with the shoulder T. The dog will then move longitudinally and will pass the shouldei' T so that the drum will be free to rotate. Power being applied to the shaft F,'the shaft Gr will be rotated through the medium of the sprocket wheels and chain and the gear wheel .R, taking motion from the shaft G, heretofore described, will turn the gear wheel Q, and communicate motion tothe drum. When the drum'is rotated slightly, th arm X descends into the recess of the drum and the upper end of said arm clears the dog w and permits the spring to force the nose of the dog into engagement with the ratchet wheel. By this means, the motion of the shaft 3 which normally rotates-freely in the 'dog w as it is carried around with the feeding and cutting roller Z, and when the said dog contacts the arm, the nose of the arm is thrown out of engagement with the ratchet wheel Y and the shaft y, is permitted to rotate independently of the vfeeding and cutting roller. Though the feeding and cutting roller comes to rest, the rollers z and 2 con tinue to rotate,' drawing the film downwardly and causing the film in engagement with the said rollers a and 2 to be severed from the body of the film on the puncture line heretofore referred to. The film thus severed will be delivered to the conveyer of the chain and belt heretofore.

iso

mentioned. The shaft 3 is driven through the medium of the gear Wheel 3 meshing with the gear wheel y on an end of the roller 2. The roller Z" is positively driven by a gear wheel a meshing with the peripheral gear 2, on the feeding and cutting roller Z, and the rollers z and 2 are preferably positively driven by being geared together at one end.

The frame N is provided with a roller N which is relatively small, around which a belt or apron travels and it has been found in practice that a film after having been carried through the developing tank by means of the belt or apron and the chains which hold the film on the belt or apron, said film being saturated, will adhere to the surface of the belt or apron to a sufficient extent to cause the said film to travel with the belt or apron from the point of disengagement of the chain with the film, which is at the shaft F until the said belt or apron starts to encircle the roller N, but owing to the abruptness of the turn over the roller, the said film will break away from the belt or api'onand descend by gravity into the pan or receptacle a which contains the fixing fluid.

The belt may be tightened or adjusted to make it run straight on the shaft F through the medium of an arm 53 which is engaged by the end of a rod 55, which rod is threaded in the lug. 56. The end of the tank has a slot F to permit movement of the shaft F. By rotating the rod 55, the arm is raised or lowered and as the shaft F is journaled in the arm, the movement of the shaft afiects the belt which runs over the said shaft. The rod 55 extends through the bottom of the casing in order that it may be reached from the outside for the purpose of manipulating the parts to effect the proper adjustment.

In addition to the hand operated means for tripping the dog U, I employ a flexible connection 57 run over a pulley 58 and connected to a bell crank 59 for tripping the mechanism to start the motor. As shown, the bellcrank is pivoted on a bracket 60 secured to one of the legs of the casing and the said bell crank has another connection 61 which extends up into the casing and is fastened to a long arm 61 of a bell crank lever, the short arm 62 of said lever acting on the stud W extending from the dog W. Any appropriate means may be provided for pulling the flexible connection 5 I extend the motor shaft 29 into the easing 62 of the pump and connect the casing of the pump with the receptacle a for the fixing fiuid through the medium of the pipe 63. The pipe 63 acts to conduct the liquid from the receptacle a to the pump casing. The pump is of the ordinary centrifugal type and the liquid which reaches the casing is acted on and is forced through the outlet pipe 64 to the sprayer pipe 65, which sprayer pipe is provided with a series of apertures dischar ing approximately horizontally and longitu inally of the receptacle a to which it is applied. The ends of the sprayer pipe are provided with caps 66 which may be removed for the purpose of cleaning the said sprayer pipe.

The holes in the sprayer pipe discharge at about the level of the liquid contained in the receptacle so that the current occasioned by the liquid catches the film as it is descending into the receptacle and acts on said film to propel. or carry it rearwardly in the receptacle and, at the same time, a current of liquid acts on the coated surface of the film and on the top of said film, the said action tending to submerge the film in the receptacle. It has been found in practice that as the film descends into the receptacle, the liquid emitted from the sprayer pipe straightens it and causes it to float rearwardly of the receptacle, as stated.

In Fig. 11, I show a hand operated device in which the belt 67 or other flexible connection is driven by the rotary member 68 which rotary member is mounted on the shaft 69 corresponding with the shaft F heretofore described. The pump 70 has a pulley 71 from which the flexible connection is run and the pump is in communication with the receptacle'a by means of the pipe 72, which pipe acts as a feeding pipe for the pump, whereas the discharge pipe 7 3 of said 74: which is of the same construction as the sprayer pipe 65 heretofore described.

WVhile I have stated that the spraying apparatus was designed to spread the film after it has been delivered into the receptacle a, I have found it desirable to provide mechanically operated means for spreading'the film which mechanically operated means may be used independently or in conjunction with the spraying apparatus. I have attained very satisfactory results by using them in conjunction with each other and in the relation shown in Figs. 2, 3, 4 and 6 of the drawings.

The mechanically operated spreading means heretofore described is shown in the drawing in the form of lengths of material which are bent to form the spreadmg members proper, each of which lengths of material is preferably bent whereby the arm 7 is formed and in which an intermediate straight portion 76 is j ournaled in a bracket 77, which bracket 77 is attached to the easing; theend of the length of material being formed into a crank 7 8 above the said bracket. As shown in the drawings one bracket and spreading member is attached at each side of the opening in the casing. A

spring 79 encircles the portion 76 and has a her in the bracket in order that the' arm may travel from the position shown in full lines in Fig. 6 to the position shown in dotted lines in said Fig. 6, as willbe seen by an inspection. thereof. The arms swing outwardly in opposite directions when power is applied to the cranked end of the member and in order to swing the said arms oppositely, it is necessary that the crank of one member be at an angle with relation to its arm different from the angle of the crank of the other member withrelation to the arm of the last mentioned member. The relation of the parts just mentioned is shown in Fig.

6 and thecranks of the members are con-.

nected by a thrust rod 80 which thrust rod has a link 81 pivoted to it intermediate its length by which motion is communicated to the said thrustrod. The outer end of the link 81 is pivoted to a collar 82, and the collar in turn is connected to an oscillating lever 83 which is journaled in a bracket 84 attached to the casing. The end of the os-' cillating lever remote from the collar is moved in one direction by .a cam 84* projecting from the side of the spur wheel 85 which spur wheel is mounted on a stud 86' anchored to the casing in any appropriate way. The spur wheel 85 is driven through the medium of a pinion 87 which is mounted on the stub shaft 20, and therefore as the developing apparatus is operated, motion is communicated to the mechanism for spreadin the film. .An inspection of Figs. 6 and 7 will show that the lever is moved by the cam 84 against the action of the springs 79 until the end of the cam is reached and at which position the arms 75 will have traveled outwardly as shown in full lines, Fig. 6,

the said arms being returned immediately thereafter to the dotted line position ofFig. 6 under the influence of the springs when the said lever has been released by the cam. The members are in such relation to the developing apparatus that the arms operate to spread each film as it is delivered to the receptacle a This same apparatus maybe employed in connection with the hand operated machine shown in Fig. 11, by providing the shaft 69"with a pinion similar to the pinion 87 and duplicating the parts of the spreading apparatus heretofore described.

The throw of the lever 83 may be regulated by moving the collar 82 thereon nearer to or farther from the pivotal point, the said collar being provided with a set screw 88, to effect the desired adjustment. 7

In addition to the mechanism for spreading the film, I provide means for "submerging the film which submerging means acts in conjunction with the other apparatus for developing and spreading'it. The embodiment of the submerging apparatus here shown consists of a frame 89 which'is a proximately rectangular in plan with the ,means for receiving means.

exception that the forward portion thereof,

stands slightly at an angle with relation to the rear portion thereof. The frame 89 has.

side extensions 90 each of which is bent in order that therear end'thereof will stand at an angle to the front portion thereof and the rear end of each extension is provided with a socket 91, designedto receive an arm 92 projecting from a shaft 93. In order to provide for a yielding action of the frame 89, the arms 92 are coiled around the shaft 93 as shown in Fig-10. While this construction'is not necessary, it has been found in practice to be quite desirable as it absorbs vibration. The shaft 93 is journaled in the side of the casing in any appropriate way and is provided with an arm 94 which extends into the path of travel of a stud 95, which projects from the dog U, thereby causing the oscillation of the frame as the dog is reciprocated. As the said dog U rises and falls by reason of the operation thereof as heretofore described, the frame 89 with the shaft 93 has a pivot. The relation of parts shown in Fig. '2, indicates that with an upward movement of the dog U, the arm 94 will be moved upwardly, thereby partially rotating the shaft 93 before causing the descent of the frame 89 into the receptacle a as shown in Fig. 4:. Thus any film that has been delivered to the receptacle 84 will be pressed into the liquidv contained therein.

While I have termed the means for immersing the film a frame it is to be under-- stood that any plunger of a skeleton or solid type designed by its weight or by pressure apphed'to it toimmerse a film shall be regarded as falling within the scope of the term.
