4 Claims.

My invention relates to improvements to terrestrial globes and more particularly to a mounting therefor.

It is one of the objects of my invention to provide a terrestrial globe, and mounting therefor, which may be illuminated by means of an illuminating lamp which is inserted in the globe.

A further object of my invention is to provide a mounting for an illuminated globe which will permit the ready removal of the globe from its mounting in order that the lamp may be inserted originally and in order that the same may be renewed from time to time.

Another object of my invention is to provide a support for the meridian ring of the globe.

For the purpose of disclosing my invention, I have illustrated certain embodiments thereof in the accompanying drawings in which:

Fig. 1 is a side elevation, partly in section, of a globe embodying my invention;

Fig. 2 is a detail section of the top pivot for the globe;

Fig. 3 is an enlarged view, partly in section, of the bottom support for the globe;

Fig. 4 is a side elevation of a modication of my invention, in which a full meridian ring is provided;

Fig. 5 is a detail section of a top pivot for the globe;

Fig. 6 is an enlarged detail section of the bottom support for the globe;

Fig. '7 is a detail section of the pivot mounting of the globe support; and

Fig. 8 is a side elevation of a portion of the meridian ring at the point where the pivot mounting is made.

In the embodiment illustrated, in Figs. 1 to 3 inclusive, I provide a base l which may be formed of stamped sheet metal, if desired, and is provided with a semi-cylindrical dome 2. Transversely extending through this dome is a slot adapted to receive the meridian ring 3 which at the point it enters the slot is provided with an enlarged boss-like portion A? provided with a screw-threaded stem 5 extending radially of the ring. In mounting the ring on the base, the ring is inserted in the slot in the dome and rests on the end walls of the slot. The stem 5 projects through a clamping plate 6 which clamps within the dome and is held in its clamped position by means of a thumb nut l. This arrangement provides for an extremely simple mounting easily assembled and disassembled, and maintains the meridian ring rigid in its upright position.

The globe 8 in the structure illustrated is preferably formed of glass having the map formed thereon by printing the map on suitably constructed paper segments which are cemented to the glass globe. The paper of the segments is suiiiciently thin to be translucent. At the bottom pole of the globe, I provide a suitable opening, suiciently large to accommodate an ordinary sized electric lamp. The walls of this opening are protected by a ring 9 which is inserted through the opening and is provided with an annular flange I overlying the surface of the globe and cemented in position to maintain the ring in place.

At the top of the lglobe I provide the usual time disc l l and at the pole the globe is provided with an opening through which is adapted to extend a hollow rivet I2 which not only clamps the time disc in position at the top of the globe but also provides a bearing opening for the globe at the top.

At the bottom of the meridian ring 3 I provide an enlarged boss I3 on which is supported the bottom globe mount and the lamp and lamp socket. To this end I provide a supporting stud lll screw threaded at its upper end and adapted to receive an ordinary lamp socket l5, preferably of the so called candelabrum type. At the lower end of this stud I provide an annular flange I6. Mounted on this stud lll and resting on the iiange i6 is a supporting disc ll carrying a guide sleeve E8 adapted to enter the opening at the bottom pole of the globe. This sleeve I8 is provided with an annular shoulder I8 over which the edge of the disc l1 is turned to form the disc and sleeve practically into a single unit and the upper edge of the sleeve i8 is rounded and inturned as at I9. The stud I4 is provided with a dat eX- tension 20 which is tted into a slotl 2| in the boss I3 and is mounted on a pivot pin 22 eX- tending through the boss. This extension 20 at one edge is formed with a ilattened abutment portion 23 which when the support as a whole is swung out on the pivot pin 22 will strike against the inner wall of the slot 2| and act as a stop to prevent the swinging of the mounting beyond a predetermined point.

At the top, the meridian ring 3 is provided with an enlarged boss 24 through which is threaded a pivot pin 25 which enters the hollow pivot I2 and provides a top pivot support for the globe. In assembly, a suitable lamp is inserted in the lamp socket l5 which may be swung outwardly on the pivot pin 22 a suiiicient distance away from the meridian ring 3 to permit the slipping of the globe over the lamp and on to the supporting disc I1. After the globe has been mounted on the supporting disc I1, it may be swung back into position within the meridian ring 3 to the point where the top pivot pin 25 may be screwed down through its boss 24 until its unthreaded end 26 passes through the hollow rivet I2. This construction provides a pivot support for the globe whereby the globe is pivotally supported at both poles and provides a ready means for providing an illuminating lamp on the interior of the globe. It is quite apparent that the lamp socket I may be provided with the usual pull-chain switch so that the light in the globe may be turned on and oiY and likewise with the usual conduit wires which, in this instance, are lead through the bottom or" the base I and out through the top of the dome 2 to be carried through a suitable opening in the disc I'I and connected to the lamp socket in the usual manner.

In the structure illustrated in Figs. 4 to 8 inclusive, I have disclosed a structure wherein the globe may be mounted in a full meridian ring. In this structure, the full meridian ring 21, for the globe, is mounted in the base I in the same manner as is the half meridian ring 3 illustrated in Fig. 1. On this full meridian ring at the bottom of the polar axis of the globe, I provide a support quite similar to the support illustrated in Fig. 3, but so mounted as to permit the lamp socket and support to be swung transversely of the meridian ring 21. To this end, I provide a supporting block 28, slotted as at 29 to embrace the meridian ring 21. At its top edge this block 28 is transversely slotted as at 3l! to receive the flattened stem 20 of the support similar to that support illustrated` in Fig. 3. This flattened stem is curved as at 3l on its underface to allow for clearance when the stem is swung on a pivot pin 32 extending through the block and the top edge of the block is curved as at 33 for clearance purposes. The slotted portion 29 of the block ts over the meridian ring and in order to make a nice fit, the meridian ring is cut out as at 34 to accommodate the block and when the block is placed in position, the end walls of this cutout portion hide the pivot pin 32. The block is held in position on the meridian ring by means of rivets passing through the block and the meridian ring. In addition to the cutout portion 34 I provide a reduced cutout portion 35 which accommodates the ilat stem on the bottom of the supporting stud I4.

If desired, I may use the same top pivot stud construction as is illustrated in Fig. 2, or I may use the modified structure illustrated in Fig. 5. In this structure, the pivot pin 36 has formed at the top thereof a clamping plate 3'I which is adapted to abut against the meridian ring 21 and is provided with a screw 38 adapted to pass through both the plate 31 and the meridian ring, and receive a nut 39 on the opposite side.

In assembly, the support is swung laterally or transversely of the meridian ring 21 a sufficient distance to allow a globe to be mounted on the bottom support. The support and globe may then be swung to a position where the globe is within the ring 21. While the globe is in its outward position, the top pivot pin 36 is inserted in its pivot hole and when the globe is swung into its normal position, the plate 31 abuts against the meridian ring and the screw 38 is inserted in position to provide a stationary top pivot.

I claim as my invention:

1. The combination with a meridian ring, of a supporting block embracing said ring, and secured thereto, a support pivotally mounted on said block, a globe supporting member mounted on said support, a lamp socket mounted on said support, a translucent globe having an opening therein to receive said lamp socket and adapted to be rotatably supported on said support and a pivot member in axial alignment with said support, mounted on said meridian ring and adapted to releasably engage said globe.

2.
