Speciflcation'ot Letters Patent.

Patented Apia 1'7, 1917.

Application medley 20, 1911. Serial No. 628,415.

To all whom it may concern:

Be it known that I, GEORGE C. BninLER,a citizen of the United States of America, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Photographing and Developing Apparatus, of which the following is a specification.

This invention relates to photographing and developing apparatus and particularly to a machine of the general character of the one covered by my reissued patent, Number 12,8353 dated July 28, 1908.

An object of thisinvention is to provide a photographing and developing apparatus having novel means for subjecting the film to the action of fluid contained within the receptacle, that portion of the invention just mentioned being regarded as a film immersing mechanism operative to press the film into the liquid in a manner to expel air from the under surface-of the said film in order that the coated surface of the film may be subjected to the action of the fluid within While this invention is applicable for use in immersing films generally', it is more particularly intended for use in conjunction with the photographing and developing apparatus which severs film into short lengths after the same has been exposed to the action of light, the said film being delivered to a receptacle containing liquid and submerged therein in order that the liquid in the container may act on the coated surface of the film.

A still further object of this invention is' to impart to the film a movement downward and slightly longitudinally of the receptacle and preferably inclining the said film in its travel in order that air contained thereun der may be permitted to escape.

A still further object of this invention is to provide novel means for operating the film immersing member in sequence with film spreading apparatus also associated with a photographing and developing appa'ratus.

A still further object of this invention is to provide means for driving the parts of the apparatus so that the elements thereof operate for the purpose of performing the functions for which they are intended.

With 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, and in which- Figure 1 illustrates a view in elevation of a photographing and developing apparatus embodying the invention with the driving mechanism omitted;

Fig. 2 illustrates an end view of the said photographing and developing apparatus;

Fig. 3 illustrates a plan view of a fragment of the apparatus shown in Fig. 1 showing more particularly the film immersing mechanism and omitting the film spreading mechanism and other parts unnecessary to an understanding of the print immersing mechanism; and i Fig. 4 illustrates a sectional view on the line 4-4 of Fig. 3 omitting. the mechanism within the casing;

Fig. 5 illustrates a detail sectional view in elevation of a developing apparatus to which the invention is to be applied.

In these drawings, I have shown a casing for a photographing and developing apparatus in which the upper part 10 contains the magazine for a roll of sensitized paper which is designed to be drawn through that portion of the casing 11 which com rises the exposing chamber to which light Isadmitted through the camera 12. The portion 13 of the casing contains'mechanism for carrying a film' through a receptacle 13 containing fluid adapted to act on the coated surface of'the film, the said mechanism being operative to deliver the said film to the receptacle 14 which is supported on the brackets 15 outside of the casing. The casing is also provided with a removable door or cover 16 and as the parts 10, 11, 12, 13 and 1(5 and the mechanism contained within the case is covered broadly by the reissue patent heretofore mentioned, the mechanism will not be described in detail.

'The power shaft 17 is provided with a pinion 18 which meshes with a gear wheel 19 for the purpose of rotating the said gear wheel 19 in the direction of the arrow, Fig. 1. The gear wheel 19 is mounted on a stub shaft 21 and the said gear wheel communicates motion to a laterally disposed cam 22 i A n the t d r i radial y as said wheel, which latter cam is tera oly on the face of the gear wheel op osite the cam 22. The manner oi driving he cams 29; is immaterial and while have shown the said came as formed with the said gear wheel i9, it is obvious that they may be otherwise associated with the shaft 21. The shaft 1? is arranged in any suitable way to communicate motion to a connection A which drives the shaft B and the feeding mechanism for drawing film G from the magazine 10 between the rollers c and c and b and Z), the said film being cut sei l into appropriate lengths and delivered to a conveyor apron belt or the like D and the chain E. The details of the feeding, cutting and conveying apparatus do not form the subject matter of the present invention in detail but are illustrated in combination with the driving); and submerging attachments to the purpose of showingtheir relation. The member l) is shown as running orer the shaft l which is in proximity to the receptacle it for containing the fluid which will act on the coated surface of the film so that film that has been run through the apparatus will be dislodged from the conveyer and delivered to the receptacle.

The film. spreading mechanism which is actuated by the cam 22 comprises two arms 24 which are angular and have portions 25 journaled in the brackets 26. The lower ends of the portions 25 have cranks 27 thereon connected by a bar 28 having-pins 99 which enter the cranks. A link 30 is pivoted to the bar 28 and has its outer end provided with a collar 31 which is adjustable on the arm 32 by a shaft, which shaft is journaled in the bracket 33 secured to the casing. The end 34 of the shaft which is opposite the arm is caused to engage the cam by which motion is communicated to the shaft and consequently to the link 30, which link, in turn, mores the spreader arms through the mechanism just described. A spring 35 operates to hold the end 34 of the shaft against the cam because it exerts a pull on the arm 32 of the said shaft. it is shown in the rawing' that the shaft, has its ends 32 and 34 standing: at angles to the main portion thereof and the ends are moved in o posite directions.

The spreading mechanism just described, forming, as it does, the subject matter of another application. will not be claimed in detail in this application but is described in detail for the reason that it coacts with the suhmerging mechanism to be presently e1- plained and as the action of the spreading mechanism and the submerging mechanism is synchronous in order to prove elfectire, it becomes desirable to show and describe how the said spreading mechanism and immersing mechanism operated from the source oif power.

The immersing mechanism here shown actuated by the cam 23 in one direction and by gravity in the opposite direction, the said immersing mechanism comprising; a frame consisting of ribs 36 connected by rods 37, the said rods supporting the pairs of posts 38 and 39, the posts 38 being slightly longer than the posts 39 in order that the immersing frame may be supported in an inclined position as shown in Fig. 4. The posts 38 and 39 are suspended from the cranks 40 and 41 respectively, which cranks are journaled in the arms 42 anchored to the casing and extend outwardly therefrom, preferably in a horizontal plane.

The ends of the cranks i1 and 40 are j ournaled, as stated, in the arms e2 and the ends thereof have fixed thereon the links 413 and 424C respectively so that the oscillation of the links communicates rotary motion to the cranks. The links 43 and 4A are connected by a bar 45 to which the links are pivotally connected and the said bar has its end provided with-a log to which rides on the cam 23. The wei hit of the frame is such that it will descend unto the receptacle 1% and carry with it any film that has been deposited in the said receptacle and it follows that as the cam 23 is rotated, the bar 4;; is elevated as the lug thereof rides over the surface of the cam. When, however, the precipitous cutaway portion 4-? of the cam comes into registry or alinemeut with the lug as, the bare?) H descends under the influence of the weight of the immersing frame, which immersing frame, as heretofore described, carries with it the film so that it is submerged within the liquid contained in the receptacle 14'. As the cam 23 rotates. the lug t6 rides up the inclined surface of the said cam and partially rotates the cranks 40 and 41 and clevotes the immersing frame to the position shown in Fig. 1, the parts being held in the position shown in 1 while the cam is rotating and the lug 4-6 is riding: on the periphery of the disk in which the cam 23 is formed. The link may be provided with a handle 4-8 by which the crank 40 may be operated independently of the mech an's n just described.

The gear wheel 19 is provided as has been stated with cam 22 which actuates the mechanism for moving the spreading arms and with a cam formed by the opt-away portion 47 allowing; movement of the bar 45 which actuates the immersing frame, it

7 being understood that the immersing frame is held in elevated position while the wheel 45 descends into the cut-away portion 47 ofprior to the time that the lug 46 on the bar the wheel. It will be observed that the immersing frame descends while the wheel 19-;

is rotating about one quarter distance of its circumference and is held elevated during the remainder of that time so that the arms 24 have'to be retained in their open or parallel positions but a slrghtfraotion of the time during each cycle of operation of the ma-- chine. The drive shaft 17 has a universal joint 49 as a-connection for a power shaft or drivingmeans.

. While I have referred to the pull-rod as operating in conjunctioii with the tripping mechanism of the patent heretofore mentioned, this pull rod may be actuated to operate tripping mechanism of other types on a photographing and developing machine, and I do not, therefore, wish to be limited with respect to the use of the pull rod in connection with a particular tripping mechanism.

From what has been stated of the operation of the elements of this device in connection with the description of the elements and their relation to other elements, it will be understood that as the machine is operated to rotate the wheel 19 the conveyer within the casing is driven to carry film toward the end of the machine containing the spreading and immersing mechanism. Itwill also be observed that the spreading arms are so mounted as to swing to the positions shown in Fig. 2 in which positions they remain while the film is partially delivered to the receptacle 14, the said arms being forced into such position by the spring 35. During the time that the film is being partially delivered to the receptacle 14, the end 34 of the shaft is in engagement with one face of the wheel 19 until that portion of the wheel 19 having the cam engages the said end 34 of the shaft and partially rotates the same. The action of the cam results in operating the spreader arms 34 so that they swing outwardly under the immersing frame and whenrin such position, the lug 46 descends into the recess forming the cam 47 and the immersing frame descends by its weight into the receptacle 14. Upon further rotation of the wheel 19, the lug 16 is cammed from the recess on to the periphery of the cam and simultaneously or nearly simultaneously therewith, the end of the cam passes the arm 34, releasing the said arm so that it swings toward the face of the wheel 19 to permit the spreading arms to return to the position shown in Fig. 2 when a repetition of the operation results, as the machine is further actuated.
