Application filed February 20, 1920. Serial No. 360,192.
To all whom it. may concern:
Be it known that ;we, SWEN Pn ULsoN and ABRAM HATCH, citizens of the Un1tedStates,
residing at Heber, in the county of Wasatch and State of Utah, have invented certain new and useful Improvements in Developing-Machines, of which the following is a specification.
This invention relates to an improved machine for developing photographic films and has as one of its principal objects to provide asimple machine offthis' character which will efiiciently operate to develop one or more films, as may be desired, uniformly.
The invention hasas a further object' to provide a developing machine employing a drum for receiving the films and wherein a developing tank will be provided for immersing the films as the drum is rotated.
And the invention has as a still further object to provide a machine whereifi the tank may be lowered away from the drum so as to permit the films to be mountedthereon and may then again be easily raised-to active position for submerging the lower portion of the drum. e
Other and incidental objects will appear hereinafter.
I the drawings:
Figure l is a side elevation of our improved machine,
. Fig. 2 is a sectional view on the line 2-2 of Fig. l, and looking in the direction of the arrows,
Fig. 3 is a fragmentary transverse section taken medially throfigh the device.
Fig. 4: is aside elevation of the developing tank employed and its elevating mechanism, and
Fig. 5 is a perspective view showing the elevating mechanism for the tank in detail.
In carrying the invention into effect, we employ a supporting frame or stand 10. This stand may be constructed of any approved material and journaled uponthe end portions of the stand is the shaft 11 of a film receivin drum 12. The exterior surface of the drum is of such character that thumb tacks or other approved fastenings may be driven into the drum. Fixed upon the shaft 11 at one end thereof is a drive wheel 13 and frictionally coacting with this drive wheel is the drive pulley 14 of a motor.
15, the motor being conventionally shown. An electric or other approved type of motor may be employed. The motor is -supin the blocks 0 -lever25. said pairs are coupling rods 26' and mounted ported by a shelf 16 which extends laterally from the adjacent end of the stand. v
For immersing the lower portion of the drum we employ a trough shaped developer tank 17. This tank may be constructed of sheet metal or other approved material and is provided at its sides with longitudinal overhanging flanges. 18. Depending from the tank at one end thereof is a waste pipe 19 m which 20 and positioned upon the lower longitudinal bars of the stand beneath the waste pipe is a vessel- 21. In connectionwith the developer tank, we employ an elevating mechanism. Seated upon the upper longitudinal bars of the stand are pairs of oppositely disposed bearin blocks 22 and journaled shaft 23; The intermediate portions of these shafts are, as particularly shownfin Figs. 3 and 5, bowed downwardly to clear the tank is lowered. Fixed.
the tank when to the shafts'23 are palrs of arms 24, one of which is elongatedto provide an operating I Connecting corresponding arms of uponthe arms at their upper ends are rollers 27 engaging beneath the flanges 18 of the tank .for supporting'the tank. Depending from the tank at one end thereof is a lug 28 and pivotally connected at one end to this 30exten'ding between the pair of legs ofthe stand adjacent the opposite end of the tank.
.each pair is a transversetea-rant cre ice.
lug is a stay rod 29, the opposite end of Thus, this rod'will hold the tank against longitudinal movement so that the handle 25 may be swung for elevating-the tank to active position as shown in Figs. 2 and 3 or for lowering the tank to inactive position as shown in dotted lines in Fig. 4. Y
In use, the tank 17 is first filled with cold water when the tank is elevated to immerse the lower portion of the drum 12. The films to be developed 'arethen, after havingpreferably been first soaked so as to render the film strips limp and pliable, helically wound upon the drum 12, the films being secured to the drum by thumb tacks or other-'ap-. proved fastenings driven into the drum and the convolutions thereof being arranged edge to edge. As the drum is" turned, in.- cident to the placing of the, films thereon, the films will be turned through the cold water bath in the tank for keeping'the filmswet so that when the operation of placing 65 v is interposed a shut off valve all .of the films desired upon-the drum is completed, the .tank may be lowered and the water therein drained through the pipe 19 into the vessel 21. After closing the shut off valve 20, the developer is then introduced into the tank when the tank is again-raisedinto active position. The motor 15 is then started for slowly revolving the drum and turning the films thereon through the developer bath. ,Thus, thev entire surface of all of the films will, as the drum turns, be immersed for uniformly developing the films. Upon the complet on of the developing operation the developer is drained ofl' and a bath of cold water again introduced into the tank for washing-the films, turning of the drum through the water bath serving,
of'course, to efiectually remove all of the developer therefrom. The films may then be removed from. the drum and placed in a fixing bath. It will accordin 1y be seen that we rovide aparticularly e cient type of mac ine and a machine which maybe easily operated.
Having thus described the invention,what is claimed as new is i 1.- A developing machine including a supporting frame, a film receiving drum joure naled thereon, pivoted tank supporting arms carried by'th frame a tank carried by said arms, and means-ho ding the tank against swinging movement with the arms, the arms being operable for elevating the tank whereby a ortion'of the drum may be immersed.
2. developing machine including asupportin frame, afilm receiving drum jourl naled t ereon, shafts j ournaled on the frame, F
arms fixed to, said shafts, a tank supported "by said arms, an
means coupling certain of the arms, the arms being movable for elevating the tank whereby a portionof the drum may be immersed.
3. A developing machine including a supporting frame, a film receiving drum journaled thereon, pivotedtank supporting means carried bythe frame, a tank freely resting on said means, and a stay rod extending between the tank and frame for holding the tank against endwise movement,-
the tank supporting means being operable for elevating the tank whereby a portion of the'drum may be immersed.
4:. A developing machine including a sup- I porting frame, a film receiving drum journaled thereon, a tank, pivoted elevating means for the tank, and means securing the .tank against pivotal movement with said elevating means whereby when said elevating means 1s rocked to coact with the tank, the-tank will beraised for immersing a portion of the drum.
.be' rocked for elevating the tank to immerse a portion of the drum.
