  • This drum of the "016 patent” is generally described as comprising, a mounting ring which serves to mount a plurality of multiple segments that collectively define a cylindrical working surface of the drum about a central axis 62 thereof.
  • Such drum is useful as a cylindrical working (forming) surface (as in the build up of a belt and tread package for a vehicle tire), or for use, in grasping the inner circumference or the outer circumference of a circular, tubular or round object (as in a transfer ring) and in which the multiple segments are each arcuate in cross section to cooperatively define a cylindrical working surface of the drum.
  • Each grouping of segments includes an intermediate segment that is mounted for radial movement inwardly and outwardly, relative to the central axis of the apparatus, and flanking side segments that are hingedly mounted to the intermediate segment on the opposite elongated sides thereof for relative hinged movement with respect to the intermediate segment as the intermediate segment is moved radially of the drum, such that their composite cross sections closely approximate a true cylindrical working surface over a range of radial movement of the intermediate segment.
  • the present invention is useful in conjunction with a drum 10 (or transfer ring) that may incorporate a main deck 12 having the capability of moving multiple elongated segments of individual arcuate cross sections radially inwardly and outwardly of the drum to collectively define the cylindrical working surface of the drum.
  • this working surface is referred to as the main deck and may be a part of a drum as disclosed in the "016 patent”.
  • the drum 10 is provided with a secondary deck 30 comprising at least two, and commonly more, subassemblies, (modules) 32 each of which is formed from an elongated central segment 34 flanked on the opposite longitudinal sides 39, 41, thereof by respective longitudinal first and second elongated lateral segments 36 and 38, respectively, which are hinged along their respective longitudinal sides of the central segment.
  • Each of these segments exhibits an arcuate cross-section.
  • the segments of each module are oriented parallel to one another in side-by- side relationship and secured in a substantially rigid attitude with respect to the central segment such that the module may be manipulated as a unitary module 32 for purposes of application and removal of a module from the drum. That is, each module may be grasped by a user's hands at locations on the opposite ends 40, 42, of the module, lifted and moved about as a unit for purposes of mounting and dismounting of the module on an existing drum without the use of tools.
  • the present invention provides a flat strip spring 50 disposed on the radially inboard side of each of the modules.
  • this spring includes a central body portion which is fixed to the inboard surface of the central segment and first and second opposite legs 56, 58 extending laterally from the central body portion 54.
  • a first one 56 of these opposite legs overlies and is attached to the first segment 36 of the module and an opposite second leg 58 overlies and is attached to the second segment 38 of the module.
  • the mounting of the spring on the radially inward concave surface 52 of the module functions to bias the first and second segments toward a position of concavity of the first and second segments relative to the central segment, while precluding material hinged movement of either of the first and second segments relative to the central segment when the module is not mounted on a drum.
  • the resistance to bending of this strip spring is chosen to be sufficient to preclude the first and second segments from folding radially inwardly of the module when the module is lifted by grasping its opposite ends 40, 42 in the process of mounting of the module on the drum or removing the module from the drum.
  • the spring readily bends as needed when the diameter of the module is changed in the course of the expansion and retraction of the modules during operation of the drum.
  • At least two modules are employed on a given drum to define the cylindrical working surface 20 of the secondary deck. More modules may be employed as desired so long as the total number of modules collectively defines the desired cylindrical working surface of the secondary deck of the drum. For example, when two modules are employed, each module defines a hemispherical working surface so that their combination defines a cylindrical working surface. In one embodiment, ten modules are employed for ease of handling of the modules as they are mounted on or removed from the drum. [0033] Each module is releasably mounted in overlying, but spaced apart, relationship to the main deck of an existing drum in a manner whereby there is provided an annular space 60 (See Fig. 1) between the main deck and the secondary deck within which the modules of the secondary deck may be moved in the course of their radial movement when the diameter of the drum is reduced or increased during the functioning of the drum.
  • the movement of the modules toward or away from definition of a cylindrical working surface of the drum is a function of the existing operational means employed by the existing drum, such as the existing operational means employed in the drum disclosed in the "016" patent".
  • Such operational means provides for radial movement of the segments of the main deck, with such movement of the segments of the main deck being substantially followed by the segments of the secondary deck.
  • the present invention positions the secondary deck radially further away from the central axis of the drum than the positions of the main deck so that minimum and maximum obtainable diameters employing the secondary deck is substantially enhanced over the minimum and maximum obtainable diameters of the preexisting drum and its main deck.
  • each of the modules on the drum is accomplished by means of manually operable locking latches.
  • the present invention provides for the "addition" of a secondary deck (outer or inner circumferential working surface) onto an existing main drum without altering the functionality of the drum so that later on the modules of the secondary deck may be removed and the drum can return to use of its main deck after the present modules have been removed from the drum.
  • Such mounting and dismounting of the modules is carried out manually, without the aid of tools.

  • the dove tail groove 80 defined in that surface 74 thereof faces inwardly of the drum in position to receive the latch housing projection 76 within such groove 80.
  • This structure and action anchors the latch housing, hence the central segment of a module, hence a module, rigidly with, but removably from, the mounting ring for the main deck.
  • the main deck movements are imparted to the modules of the secondary deck in a manner which causes the segments of the secondary deck to follow the movements of the segments of the main deck, but with the movement of the segments of the secondary deck being within a range of diameters, each diameter of which is larger than the largest obtainable diameter of the drum when employing only its original main deck.
  • the receiver 78 for the latch 64 associated with the secondary deck module may also comprise an elongated camming guide 84 as will appear thereinafter.
