Definitions

  • a tank for treating photographic material contains an elongated upright support member on which a plurality of axially spaced pairs of disks members are surroundingly carried.
  • a retaining element also surrounds the support member for retaining the disk members against axial movement and cooperating engaging portions in form of recess and projections or the like are provided on the retaining element and at a plurality of axially spaced locations of the support member so that the retaining element can be connected with the support member at different locations.
  • the present invention relates generally to devices for the treating of photographic material, and more particularly to devices for treating photographic strip material.
  • one feature of the invention recites in a device for treating strips of photographic material, in he combination of an elongated upright support member and a plurality of axially spaced pairs of disk members surrounding and carried by this support member.
  • a retaining element also surrounds the support member and retains the disk member against axial movement, and cooperating engaging portions are provided on the retaining element and at a plurality of axially spaced locations of the support member for permitting positioning of the retaining element on the support member at such locations.
  • the engagement of the cooperating engaging portions assures that the retaining member will be reliably positioned and retained on the support member, so that the pretension of the retaining member itself can be kept low without disadvantage.
  • the number and position of the engaging portions can be readily accommodated to the various possible combinations of spiral disk members so that 0 the construction is very versatile.
  • the invention can be executed in various different ways. According to a further embodiment it is particularly advantageous to have the engaging portions be self-locking in their interengagement, and in a particularly simple and easy utilization of the device according to the present invention is possible if, according to a further embodiment, the retaining member is in form of an annulus which is circumferentially incomplete, that is to say has a gap in its circumference, and is provided with two projections at its circumference diametrally or substantially diametrally opposite the gap which can be manipulated in order to widen or reduce the gap. According to an advantageous construction the cross-sectional configuration of such a member will be substantially H-shaped, and manipulation of the projections will result in an increasing of the width of the gap so that the annular portion can readily be placed about a cylindrically configurated support member.
  • the retaining member can also be in form of an elastically deformable ring member which carries approximately two axially parallel arms each having one portion extending in one axial direction and another portion in the other axial direction.
  • the portions which extend in one common axial direction are provided with engaging portions and the other portions serve as the counterparts of the aforementioned projections which, when displaced towards one another, make the projections move apart from one another so that the member can be placed onto the support member.
  • the axial dimension of the member is larger than in the preceding one.
  • the support member is cylindrically configurated and provided with angular grooves in its outer circumferential surface
  • the retaining member is provided with inwardly directed abutments such as curved ribs or the like which can snap into these grooves.
  • the support member it is also possible to provide the support member with at least one or several longitudinally extending rows of abutment portions, such as teeth or the like which advantageously are recessed in the outer circumferential surface of the support member.
  • FIG. 1 is a partly sectioned side view of a device according to the present invention. 4
  • FIG. 2 is a top-plan view of a detail of FIG. 1;
  • FIG. 3 is a section taken on line 3--3 of FIG. 2; and
  • FIG. 4 is a perspective view of an element embodying a further concept of the invention.
  • FIG. 1 we have illustrated a developer tank for film strip material which is in form of an approximately cylindrical casing having a circumferential wall and a bottom 11.
  • a cover 12 can be screw-threadedly connected with the upper open end of the casing.
  • a centering projection 13 Centrally of the bottom wall 11 a centering projection 13 extends into the interior and is provided with several spacer ribs 14 which extend outwardly from it.
  • angular ribs could also be provided for centering and light-retarding or shielding purposes in place of the pin or projection 13.
  • the cover 12 is provided with a central nipple in known manner, in which a funnel-shaped portion terminates which can be closed with a cap 15 and serves for the fluid which is to be introduced in order to treat the film strips.
  • a here tubular support member 16 is provided into one end of which the nipple extends whereas the bottom flange 17 of the support member 16 surrounds the pin or projection 13.
  • a plurality of pairs of spiral disks 18, 19 and 20 are arranged on and surrounding the support member 16 at axially spaced locations of the latter, and each of these pairs of disks is capable of retaining a non-illustrated strip of photographic material, such as films, roll films, photographic paper or the like. Because the details of the disk members of the pairs 18, 19 and 20 are not of importance for the present invention, these members have been illustrated only rather diagrammatically in FIG. 1.
  • pairs of disk members 18, 19 and 20 cannot move (or at least not significantly move) in axial direction of the support member 16 during the use of the tank illustrated'in FIG. 1, that is during shaking, tilting or the like which is necessary in order to process the film material which is to be retained between the disk members of the respective pairs.
  • a retaining member is provided which embraces the support member 16 and engages the adjacent pair of disk members to prevent them from displacement.
  • the support member 16 is provided with a plurality of engaging portions in form of annular grooves 21 in its outer circumferential surface, these engaging portions being axially spaced at such locations where the provision of the retaining member may be necessary.
  • the retaining member itself is identified with reference numeral 22 and one embodiment is shown in FIGS. 2 and 3. It will be seen that in end view or in cross-sectional view it is approximately I-I-shaped and has lateral projections 23 and a transverse portion 24.
  • the end portions of the lateral projections 23 which are located above the transverse portion 24 are arcuately curved towards one another so as to define an annulus which is circumferentially incomplete, that is which has a gap in its circumference.
  • the lower portions 26 of the projections 23 are approximately straight and constitute handles.
  • the end portions 25 are each provided with an inwardly facing curved rib 27 extending in circumferential direction of the arcuate configuration and having a profile which mates with that of the annular grooves 21.
  • the member 22 is of elastic material, preferably synthetic plastic material and pressing of the portions towards one another causes the portion 24 to be elastically deformed so that the area surrounded by the portions 25 becomes larger, that is the portions 25 move apart and the gap between them becomes widened.
  • This makes it possible to put the member 22 easily around the support member 16 and to move it along until it is in the required position in which the ribs 27 engage in the respectively desired annular groove 21 after the portions 26 are released whereby the portions 25 will elastically return to their original position and the ribs 27 will enter into the groove 21.
  • Reliable retention against axial displacement of the member 22, and consequently of the disk members of the pairs 18, 19 and 20, is achieved in this manner with even a small elastic pretension.
  • FIG. 4 differs from that in FIGS. 1-3 in that a ring portion 28 is elastically deformable and provided with two pairs of double armed levers 29 and 20 which in the illustrated embodiment are of one piece with the ring portion 28 and extend in approximately axial parallelism.
  • the arms 31 of the levers 29 I and 30 are each provided with a rib 32 which can engage in one of the grooves 21, and which may be of wedge-shaped profile as shown, and the arms 33 are handles which replace the portions 26 and have the same purpose as the latter.
  • This member also, is advantageously made of deformable synthetic plastic material which is elastically yieldable.
  • the illustrated embodiments are exemplary only and that the invention should not be considered limited thereto.
  • the retaining member it is not necessary for the retaining member to surround and almost entirely surround the support member 16.
  • the retaining member surrounds the support member through an arc of 200.
  • the retaining member could also be non-symmetrical in its construction, for instance of sickle-shaped configuration so that it could be hooked with a free end of the curved portion (provided with a projection) into a recess such as a cutout in the support member, and the curved portion could be pressed against and onto the support member,
  • annular grooves 21 could be replaced by one or more axially extending rows of engaging portions provided in the outer circumferential surface of the support member, preferably recessed in this surface.
