PHOTOGRAPHING AND DEVELOPING APPARATUS.

Application filed February 3, 1909.

To all whom it may concern Be it known that I, GEORGE C. BEIDLER, a citizen of the United States of America, residing at Oklahoma, in the county of Okla homa and State of Oklahoma, have invented certain new and useful Improvements in Photographing and Developing Apparatus, of which the following is a specification.

This invention relates to a photographic and developing apparatus and particularly to a reproducing machine by which drawings, printed and written documents, and records may be photographed.

An object of this invention is to produce a machine having a supply of sensitized material, preferably of film, wound on a roll and adapted to be unwound therefrom for the purpose of exposing the film to light, and in combination therewith, novel means for severing the film after it has been exposed and developed.

A further object of the invention is to produce a machine of the character noted having means for supplying film to be exposed and means for exposing said film as well as a novel receptacle for containing developer in operative relation to means for exposing the film to light and means for drawing the film through the receptacle.

Furthermore, an object of the invention is to provide a receptacle for the developer and a drain pan associated with the receptacle, means being provided for detachably holding the receptacle in the pan, the pan and receptacle being incased but applied to the casing in such a way that they may be removed for the purpose of repair or for the purpose of cleaning the receptacles.

A further object of the invention is to produce a machine having a pan containing fixing fluid, said pan being provided with a hood secured to the casing; the casing being provided with a support for the pan, which pan is in position to receive the severed developed films after they are projected from the casing.

A'further object of this invention is to produce a novel cutting mechanism in which astationary and a movable knife are emplo ed. the said movable knife having a vieldable pivot in order that it may adjust itself with relation to the stationary knife, means being also provided for reciprocating the movable knife and exerting pressure thereon laterally. r \Vith the foregoing and other objects in Specification of Letters Patent.

Serial No. 475,791.

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 specificatic-n, wherein like characters denote corresponding parts in the several views, in which Figure 1, illustrates a side elevation of a photographing and developing apparatus embodying the invention; Fig. 2, illustrates a longitudinal, vertical sectional view through the developing tank and fixing pan, a fragment of the bellows and magazine being shown; Fig. 3, illustrates a perspective view of a movable knife and the means for operating it; Fig. 4-, illustrates a view in elevation of the side of the developer tank, partly broken away to show a drum, said view also illustrating the bracket for supporting the drum and the gearing for the feed rollers;'Fig.' illustrates a sectional view of the bellows showing the application of the ground glass thereto for the purpose of obtaining proper focus; Fig. 6, is a. detail view of the pivot for the movable knife, a fragment of said knife being shown in plan; Fig. 7, illustrates a view in elevation of the stationary and movable knives having means connected to the movable knives for imparting motion to one of the feed rollers; and Fig; 8, is a detail view of the ratchet wheel and parts operating therewith. Fig. 9 is a detail sectional view of the feeding rollers, a tension device being shown in them. Fig. lOis a view in elevation of a bracket.

In these drawings A, denotes a bellows having a lens box B, and a lens C. The lens box is here shown as in position to operate in conjunction with a horizontally disposed supporting table (not shown) adapted to contain copy for the material to be photographed, but as the means for supporting the copy is an immaterial detail of construction. it is not illustrated. The bellows frame D, has a stud E, on each side adapted to engage a. hook D or the like by which the casing F. is held in operative relation to ported by the base and is held in operative relation thereto by means of hooks H, which engage screws or studs 1.

The casing F, contains the magazine f, which is provided with bearings such as F for a core J, of a roll of sensitized material, and the said sensitized material is drawn from the roll and through an opening F between the casing and the bellows frame in order that the said sensitized material may be exposed to light as it passes from the magazine to the developing tank. The casing, furthermore, has a partition K, therein forming the bottom of the magazine and said partition has a bracket L, secured to it near one end.

The side walls of the casing at their lower edges are provided with brackets M, havin apertures Z to receive the journals N, or the drum 0, hence when the casing is removed from the base and bellows frame, the drum is removed with it. Each bracket M, is provided with an elongated bearing designed to receive the shaft P, of the upper feed roller Q. The shaft P, is further mounted in an arm It, at each end, each arm P, being pivotally mounted on a pin or stud n, projecting from the inner surface of a. bracket M. In order to hold the arm R, and the shaft P, normally depressed, a spring T, has a looped portion encircling the stud S, and one extremity of said spring bears on the shaft P, whereas the other extremity t, of said spring is anchored to the bracket M, hence it is by this construction that the feed roller Q, is moved with relation to the feed roller U, which feed roller U, is secured to a shaft to. The shaft P extends through one of the brackets M and the shaft u extends through the ends of the tank Y as shown in Fig. 1. The shafts P and u are provided with gear wheels V and r, respectively, and the lower shaft u, projects beyond the side of the casing and has a crank XV, thereon, by which the shaft is rotated. The sensitized element, viz., paper or the like, is shown at X, and it will be ob served that it passes around the drum 0, and between the rollers Q and U, and that by turning the crank the sensitized element is drawn from the magazine, past the ex posing chamber and into the tank Y.

The tank Y, is designed to contain developing fluid and is preferably Ushaped in cross section and is provided with a sup port Z, at each end, said Support having a foot 2, with an aperture to receive a stud .2, which projects from the bottom of the drip pan Z. The drip pan has a depending tube Z extending through an aperture in the J is provided for the feet of the support of the tank remote from the bellows side of the casing and as shown in Fig. 2, the upper e lge of the side wall of the tank lies under a bracket 8, secured to the bellows frame. in practice I utilize two of these brackets 8, one near each end of the tank and they act as braces to prevent movement of the tank, especially as the feet of said tank are well anchored through the medium of the studs 2.

I have found it desirable to sever the sensitized element after it has been exposed and developed and to deliver the severed portions of the sensitized elements to a pan 9, containing a fixing fluid. The wall of the casing is cut away to form an opening 10, through which the sensitized element is projected into the pan 9.

The cutting apparatus is mounted in conjunction with the bracket L, which has a sleeve 11, extending therefrom, the said sleeve being in line with an aperture formed in the bracket, which aperture and sleeve are designed to receive the pivot 12, on which the movable knife 13, is mounted and secured. lhe pivot 12, is provided with a collar 141-, and a spring 15, interposed be tween the collar and the end of the sleeve, which spring acts to hold the pivot normally projected rearwardly. and the inner end of said pivot provided with a head 16, bearing against the knife .13, which is apcrtured to receive the pivot. The action of the spring 15, is, therefore, to draw the movable knife toward the stationary knife 17. which stationary knife is mounted on the lower end of the bracket L. The sleeve 11, is provided vith a diagonally disposed slot 18, and the pivot 12, has a pin 19, riding on the edge of the diagonally disposed slot 18. the camming action of which causes the pivot to more longitudinally in its bear ings against the action of the spring 15, in order that the movable knife may be permitted to clear the edge of the stationary knife.

In order to operate the movable knife, an arm 20, is applied to a recess 21, of said morable knife near the end opposite the pivot and said arm 20, projects from a collar 22, secured to a shank 23, of an oscillating handle El. and the shank is movable in one end of the casing. The outer extremity of the arm has an angular portion 20 which acts as a cam for the movable knife and pre s it downward toward the stationary knife, while moving its cutting edge past the stationary knife, that is to say the said arm will impart to the mova lateral pressure tending to force it against the cutting edge of the statirmary knife, thus insuring proper action of the knives in operation. Owing to the lateral pressure imparted to oneend of the knife by the arm and the movement given to the pivot of the knife by the cam on the sleeve which permits the pivoted end to move slightly in a direction opposite to that im parted to the outer end of the knife by the arm, the knife has what might be termed a slight oscillatory motion with relation to the stationary knife and the stationary knife would act as a fulcrum for the pivoted knife. Unusual pressure is, therefore, applied to the contacting surfaces of the knives and positive cutting action is insured. After a film has been severed by a complete stroke of the knife, the pivot of the knife is retracted by the spring on the pivot as the knife swings upwardly under the influence of the spring 25. The movable knife is held normally elevated through the medium of the spring 25, which is secured to a screw 26, in said knife and to a screw 27, in the partition K, hence the said arm 20, operates the knife against the action of the said spring.

I have found in practice that when a sensitized element such as paper becomes wet, it has a tendency to buckle and owing to the fact that the movable knife is pivoted at one end with relation to the stationary knife, the space between the knives near the pivot of the movable knife is rather restricted and hence, when the sensitized element buckles, it is apt to abut the movable knife when the feed rollers are manipulated and when this occurs, the operation of the apparatus is impaired. There are several ways of obviating this difficulty, one of which is to have the knives slightly longer than they are actually required to be for severing the film in which event the restricted opening between the two knives is removed from the edge of the sensitized element, and another way is'to impart to the sensitized element a slight projecting movement immediately after a print has been cut therefrom, thus causing the end of the sensitized element to pass beyond thecutting edge of the knife for any buckling thereafter would not affect the operation of the apparatus.

As a means for carrying into effect this latter idea for projecting the end of the sensitized element, I may extend the shaft P, in the opposite direction to that having the crank and provide it with a ratchet wheel 28. I then pivotally mount on the end of the shaft P, an arm 29, carrying a spring pressed dog 30, adapted to engage the teeth of the ratchet wheel. A link 31, is pivotally connected to the arm 29, and said link is connected to a lever 33, pivoted on a bracket 32, which may extend from the partition K, of the casing The inner end of the lever 32, is connected through the me dium, of the link 33, with an ear 34, on the knife 35. In the form shown in Fig. 7, the knife 35, is movable. and acts in con unction with the stationary knife 36. In this form,

an arm 37, similar to the arm 20, is used for the purpose of actuating the movable knife.

As shown in Fig. 5, the apparatus is focused by applying to the bellows frame D, having the bracket 8, a ground glass 39, in a suitable frame 38, and in order to apply the ground glass frame, it is necessary to displace the removable section of the casing.

The operation of the apparatus will be as follows: The proper focus having been attained and the casing having been applied to the base, the feed roller P, removed with the casing will be restored to its operative relation to the feed roller U. The sensitized element will then be in position between the two rollers and when motion is communicated to the lower roller through the medium of the crank, the said rollers will be driven in unison through the medium of the gearing V and 1), thus a positive feeding action will result and as the springs I, press the two rollers together, sufficient friction is produced between the rollers and the sensitized element to insure positive feeding action of the said sensitized element. After the sensitized element has been exposed and drawn into the developing tank and is acted on by a chemical therein, it is projected between the knives and through the opening in the casing to the pan 9. lVhen a given length of the sensitized element has passed between the knives, the knife operating mechanism is pressed so that the sensitized element is severed, the severed length finding its way into the pan 9, containing the fixing fluid. In order to prevent light from gaining access to the pan 9, the said pan is provided with a hood 39, which may be of any well known con struction, but it is preferably of the construction shown herein and specifically claimed in a companion application filed by me July 10, 1908, Serial Number 442,877, and as said hood is fully described in said application, it will not be described in detail here.

\Vhen the apparatus shown in Fig. 7, is employed in connection with the knives, it follows that when the pivoted knife descends, the lever 32, will be oscillated on its pivot and the arm 29, will be moved to carry the dog 30, into engagement with teeth in advance of the one engaged by it as shown in Fig. 8. After the knifehas descended the full stroke and the knife operating mechanism is released, the spring 25, will elevate the knife and oscillate the lever 32, in order to carry the arm 29, back to the position in which it is shown in Fig. 7, and with the return of the arm to said position, the ratchet wheel 28, will be partially rotated, and hence the shaft P, will partially rotate and communicate motion to the feed roller thereof and to the companion feed roller acting in conjunction with it, and thus the edge of the sensitized element will be carried beyond the knife and the sensitized element will be free of any obstruction when power is again applied to the feed rollers.

The casing has an opening in front in communication with the bellows and after the sensitized element comes to rest in the opening, it may be exposed to, light. The opening is also provided with a guide which is attached to the side edges of the opening, and the said walls of the opening are further provided with slots to receive a dark slide.
