June 2, 1931. P. J. KING SPHERICAL GEOGRAPHICAL GLOBE Original Filed Dec. 12, 1930 Pete J INVENTOR BY ATTORNEY Patented June 2, 1931 PETER J. KING, OF DETROIT, MICHIGAN SPHEBICAL GEOGRAPHICAL GLOBE Original application filed December 12, 1930, Serial No. 501,815. Divided Serial No. 272,015.

This invention relates to improvements in spherical geographical globes, and aims to provide a cheap form of globe consisting. of two substantially hemi-spherical portions the margins of which overlap so that a joint is made therearound.

Another object of the invention is to provide a globe wherein opposed openings are provided through the sections for the passage of a post which extends substantially at right vide a them that they conform substantially to the curvature of the globe. I

Still another object of the invention is to provide a spherical geographical globe having a time dial mounted thereon insuch a manner that practically thewhole of the surface of the globe remains visible.

Preferred embodiments of the invention, which consists in certain novel construction and combination of parts, is hereinafter more fully described with the aid of the accompanylng drawings, in which Figure 1 illustrates a side elevation of the invention, and

Figure 2a is a sectional view thereof.

Figure 2b is a detail of the joint between the two hemi-spherical sections, enlarged.

. igure 3 is a plan View of the globe and time dial.

Figure 4 is a side view of one of the gores before it is applied.

Figure 5 is a fragmentary view of the globe in section without the gores, showing a slightly modified construction.

Referring to the drawings, 1 and 2 designate two substantially hemispherical portions usually made of metal. The margin 3 of the portion 1 overlaps an annular flange 4 of lesser diameter than the margin of the portion 2 and integral with the latter. This a very small portion of the surface and this application filed April margin 3 is preferably soldered, or otherwise suitably secured, to the flange 4. 4

Substantially centrally the portions 1 and 2 are provided with opposed openings 5 and 6 around which annular recesses 7 and 8 are formed. In the construction shown in Figure 2a, 9 denotes a tubular member having a flanged end 10 which rests in the recess 7 and its opposite end 11 is rolled, or expanded, to take into the recess 8. In Figure 5 the construction is varied so that short bushings 10a and 11a extend inwardly through the openings 5 and 6 respectively for a short distance only.

The tubular member 10a and 11a, provides a hollow axis for the globe so that the latter may be turned about a post 12. The lower end of the latter is threaded at 12a for attachment to an ordinary declination arm 13, and 14 designates a washer between the arm and the underside of the globe, and concave on its side adjacent to the latter. The upper end 12?) of the post is also threaded to receive a nut 15 under which a washer 16 is provided. 17 indicates a timediahthe hub 18 of which is arranged around the nut 15 so that the dial may be turned independently of the nut. The- 9, or the bushings annular margin 19 ofthe time dial is marked off by hours in the conventional manner, and the margin is also inclined at a considerable angle to the surface of the globe so that only of the latter is obscured by it.

Around the surface of the two hemispherical portions 1 and 2, and preferably at right angles to their joint, a plurality of gores, or segmentsQO, are attached. These gores are preferably both printed and shaped, asshown in Figure 4, prior to their application, and are secured in place by means of a suitable adhesive. The ends of all the gores extend under, and are hidden by, the washers 14 and 16.

The method of forming the cover of the globe from a plurality of pro-shaped gores is covered by my copending divisional appli-v cation, Serial No. 501,815, filed December 12, 1930.

WVhile in the foregoing the preferred forms of construction have been described and shown, it is understood that the construction is subject to such further modifications as fall Within the scope of the appended claims.

\Vhat I claim as my invention and desire to secure by Letters Patent is:

1. The combination with a globe and a post extending therethrough, of a time dial rotatably mounted on and secured to said post having an annular margin disposed angularly at a considerable angle to the surface of said globe.

2. In combination, a spherical geographical globe, a post at the upper pole end, and a time dial mounted around said post, said time dial having an annular margin disposed angularly to the surface of said globe;

PETER J. KING.
