  • This invention relates to marine lanterns and particularly to improved universally adjustable mount assembly for positioning a light source relative to the focal point of a lens system.
  • such marine lantern apparatus broadly includes a base member or lantern pot, a lens assembly mounting ring pivotally connected to said base member and securable in gas and water tight relation thereto, an omnidirectional drum lens member mounted on said ring, a cover member for said drum lens securable in gas and water tight relation to said ring and a contained bracket mounted lampchanger assembly for providing the light source for said lantern.
  • This invention may be briefly described as an improved mounting assembly for a lampchanger supporting bracket in marine lanterns of the type described that permits accurate manual adjustable positioning of the light source relative to the focal point of the lens system and replacement of the bracket mounted lampchanger assembly without disturbance of the focal point positioning of said light source.
  • the invention includes an adjustable tripod type mounting system for the selective manual positioning of a bracket mounted object relative to a predetermined point of reference.
  • the object of this invention is the provision of an improved universally adjustable mount for the selective manual positioning of a bracket mounted object relative to a predetermined point of reference.
  • Another object of this invention is the provision of an improved adjustable support for a bracket mounted lampchanger assembly in marine lanterns to permit the selective manual positioning of a light source relative to the focal point of a lens system and permits replacement of said bracket mounted lampchanger assembly without disturbance of the focal point positioning of said light source.
  • FIGURE 1 is a plan view of a lens assembly mounting ring of the type incorporated in the aforementioned application Ser. No. 46,246.
  • FIGURE 2 is a section on the line 22 of FIGURE 1 taken in the direction of the arrows shown, but inverted.
  • Such lanterns conventionally include a lampchanger assembly incorporating a plurality of light sources and is adapted to automatically replace the light source upon failure thereof.
  • lampchanger assemblies are of conventional construction and commercially available assemblies thereof are well known to those skilled in this art. In the interests of clarity and brevity, therefore, the details of such a lampchanger mechanism will not be herein described, although, as explained later, such a unit will be assumed to be mounted on a bracket member sized and shaped to be cooperatively associated with the mounting system forming the subject matter of this invention.
  • a lens assembly mounting ring 26 suitably formed of cast aluminum with accurately machined surfaces and which, as described in detail in the abovementioned copending application, is adapted to support the lens system and to be disposed in gas and water tight hinged relation with a base member or lantern pot.
  • the illustrated mounting ring 26 is in the form of an annular ring having a plurality of inwardly and upwardly directed, specifically three in the illustrated embodiment, integral lampchanger assembly mounting bracket support arms 76.
  • Each of the support arms 76 has a non-rotatable dependent stud 78 terminally mounted thereon and provided with a flat 80 on the surface thereof.
  • each of the individual lampchanger mounting bracket positioning assemblies are identical in construction, only one thereof will be described in detail, it being understood that universal adjustment requires at least a tripod type mount and at least three such assemblies.
  • a biasing spring member disposed in surrounding relation with the stud 78 and positioned adjacent to the underside of the terminal portion of the support arm 76.
  • a bushing member 142 Disposed beneath the spring member 140 and biased downwardly thereby is a bushing member 142 having an extending flanged top 150, a reduced diameter neck portion 152 and an enlarged body portion 154 having a threaded set screw receiving aperture 156 therein containing a set screw 144 positioned to engage the flat 80 on the stud 78.
  • a collar or cup member 146 Surrounding the body portion 154 of the bushing 142 is a collar or cup member 146 having an enlarged aperture 147 in the side wall thereof to permit passage of the set screw 144 therethrough and a limited degree of displacement relative: to said bushing member.
  • the collar member 146 is supported in surrounding relation to the stud 78 and bushing 142 by a manually rotatable Wing nut 148 and is biased downwardly relative tosaid bushing member by a spring washer 158 disposed intermediate thereof.
  • the terminal portion of one of the arms of a suitably shaped three armed lampchanger assembly mounting bracket 160 is placed in surrounding relation with the reduced diameter neck portion 152 of the bushing 142. with its upper surface disposed beneath the lower surface of the flanged top portion thereon and its undersurface supported by the upper end of the collar 146.
  • the set screw 144 is backed off and disposed out of engagement with the flat 86 on the stud 78 vertical positioning of the terminal portion of said mounting bracket is effected by manipulation of the wing nut 148.
  • the tripod type mount consists of three support arms, each with an independent adjusting mechanism as described above, a universally adjustable support is provided for the lantern light source.
  • the desired positioning thereof may be effected by manipulation of the wing nuts 148 so as to align the light source filament with suitable target markers or other indicia indicative of a predetermined location therefor.
  • the set screws 144 are tightened, thus locking the bushing members 142 on the studs 78 and fixing the position of the lampchanger assembly support bracket 160.
  • the above described assembly permits removal and replacement of a bracket mounted lampchanger assembly in marine lanterns without the necessity of a refocussing operation upon replacement thereof. It will also be apparent to those skilled in the art that the herein described tripod type mounting system may be utilized in other than marine lanterns and will be of general utility wherever universal positioning of a bracket mounted object relative to a predetermined point of reference is required.
  • a mounting assembly for adjustably positioning an article supporting bracket comprising a fixed support arm, a stud member extending from said support arm, a bushing member having an extending top portion with an exposed undersurface and a dependent body portion mounted on said stud and longitudinally displaceable relative thereto, means disposed intermediate said support arm and the top of said bushing member for normally biasing the latter in a direction away from the support arm, a collar member disposed in surrounding relation to the body portion of said bushing member sized and shaped to have its upper defining edge selectively spaced from the exposed undersurface of the top portion of said bushing member for defining a bracket receiving location disposed therebetween, means for longitudinally displacing said bushing and collar member relative to said stud and means for selectively locking said bushing member at a selected location on said stud member to fix the position of said top portion thereof relative to said support arm.
  • a mounting assembly for adjustably positioning an article supporting bracket comprising a plurality of fixed supporting arms having terminal portions disposed in predetermined spatial relationship to each other, a stud member fixedly mounted in and dependent from the terminal portions of each of said support arms, a bushing member having an extending top portion with an exposed undersurface and a dependent body portion mounted on each of said studs and individually longitudinally displaceable relative thereto, means disposed intermediate the terminal portions of each of said support arms and the tops of said bushing members for normally biasing the latter in a direction remote from said support arms, a collar member disposed in surrounding relation to the body portion of each of said bushing members sized and shaped to have its upper defining edge selectively spaceable from.
