Replogle globe dating
If you are interested in a quick reference guide to determine the decade your globe was made we suggest our other Globe Dating Guide, which is a brief list of changes arranged roughly by decade and is short enough to be printer friendly.Depending upon the maker, 1930's world globes will often have metal bases and full meridians, the longitudinal marker which circles from pole to pole.This will help you determine whether a globe is worth keeping as a family heirloom, or perhaps auctioning off to collectors.The first step to determining a globes age is to know its manufacturer and the time when the manufacturer was in operation.A method of manufacturing a raised relief, illuminated globe includes printing a hemispherical map design on a flat vinyl plastic sheet, forming the vinyl plastic sheet into a substantially hemispherical shape, positioning the hemispherically formed sheet in a mold cavity, positioning a mold core on... Thus, an object of the present invention is to provide an improved globe with a relief surface and to provide a method for manufacturing a globe with a relief surface.A method of manufacturing a raised relief, illuminated globe includes printing a hemispherical map design on a flat vinyl plastic sheet, forming the vinyl plastic sheet into a substantially hemispherical shape, positioning the hemispherically formed sheet in a mold cavity, positioning a mold core on the back side of the sheet, injection molding a styrene backing for the hemispherical shaped sheet to conform the sheet with the mold cavity including relief areas defined in the cavity wall, and removing the molded hemisphere from the mold. A further object of this invention is to provide a method of manufacturing a globe with a relief surface that avoids the inaccuracies of conventional manufacturing techniques.
Do you have an old globe that has been around in the family for decades, or found an antique-looking orb in a flea market and want to assess its age and authenticity?
A second molded hemisphere is produced in substantially the same manner and is attached to the first hemisphere to form a complete globe. Another object of the present invention is to provide a method of globe manufacture wherein the relief areas are formed simultaneously with providing a solid, rigid backing for the globe form.
The printed map design of the globe is positioned in the mold cavity to insure that the relief areas are properly positioned with respect to the design.a rigid, thin walled, molded plastic inner wall with an outside surface adhered to said outer sheet and defining a relief pattern impressed on the outer sheet by the outside surface of the inner wall, said inner wall having a generally smooth, uniform inner surface, said inner wall having sufficient thickness to maintain and define the shape of the globe. Globes or spherical representations of the earth having relief areas were known at least since 1962, see e.g., Case, U. Another object of the present invention is to provide a globe with a relief surface and a method for manufacturing such a globe in which the relief areas have greater structural integrity and durability than is achieved by prior art globe manufacturing techniques.
If you are lucky, you just may be looking at a centuries-old globe.
Knowing a globes age is one of the first things you should do to find out its value.
