globe and support to be moved readily from place to place; yet another feature of this invention is that the support may be moved with very little physical effort; other features and advantages of this invention will be apparent from the following specification and drawings, in which Figure 1 illustrates the globe and support being moved; Fig. 2 is a detailed sectional view of the socket; Fig. 3 is a view of the base along the line 3 of Fig. 1; Fig. 4 is a view of another embodiment of this invention; Fig. 5 is a view along the line 5 of Fig. 4; and Fig. 6 is a sectional view on the line 6 of 4.

It has been quite common to mount globes in supports having a base adapted to stand upon the floor of the room in which the globe is being used. In order to provide a firm support, however, it is necessary that the base have a large diameter. This is generally achieved by having a base which com rises three or more legs extending outwardly from the central support. The entire assembly is usually rather heavy and cumbersome, and thus difficult for a teacher or pupil, for example, to move from place to place in the room, or even to another room. Casters have been used on the bases in order to assist in movement. Such casters, however, become rusted or stuck in one position after long disuse, and thus prevent easy guiding of the support when it is being moved. Such casters, moreover, are of small diameter, and thus are very diflicult to move over along slight projection in the floor, as a threshold or the edge of a rug.

This invention provides a globe support and base which obviate these difficulties. The base member is made in the form of a wheel, and is of suflicient weight and diameter not only to serve as a firm base, but also to act as a counterweight when the support is inclined from the vertical position. The base, or wheel member, is also provided with a peripheral traction member or the which prevents the base from slipping out from under the support when the support is inclined. It will be readily apparent that when the sup port is inclined, the base serves as a wheel member and counterweight, permitting ready movement from place to place with little physical effort and with no interference from intervening projections above the floor level.

In the particular embodiment of this invention illustrated in Figs. 1, 2 and 3, the base wheel memher is. indicated by the reference numeral It. The base member has centrally mounted therein, and perpendicular thereto, a support or standard 5 H, here shownas a pipe or tube. The support receives therein an extension member or rod I2, which extension member may be locked at any desired point, as by the wing nut IS. The extension member has mounted thereon a socket 10 [4, which socket is formed integral with the yoke 5.- The yok has. th U- p upp r n members 86 which yieldingly engage an annulus H, which annulus has, a globe l 8 mounted therein on its polar axis 19,. The reference numeral 2o ndicates a person in the act of moving the globe and.- support, showing the hand 2! grasping the annulus and the hand 22 grasping the yoke of the support.

Referring more particularly to Fig. 2, the socket I4 is shown as having a recess or opening 23'which receives the extension member l2. The extension member l2 has near the upper end thereofa. circumferential recess or slot 26, which slot is adapted. to receive the end of a plunger 25. 5 The plunger is yieldingly mounted in a housing 26;, whichhousing is mounted in the socket M, and has an exterior handle portion 27. The construction of the socket forms a firm support and connection between the yoke and the extension 30 member, and yet permits. ready rotation of the one with respect. to the other. When it is desired to disassemble the support, the socket may be removed from the extension member by pulling out the handleportion 2'! sufficiently to disengage the plunger 25. from the slot 2v Referring more particularly to Fig. 3, the base member ID is shown downwardly turned towards its edge 28. The member is provided, near its edge, with depressions or grooves 29 and 30, 0 which grooves are adapted to receive the ends ofv a. split tube or tire 3!. The base l0 may be of any desired heavy material as iron, which material is prevented from contacting the floor by the frictional member or tire 3 I. It will be noted 4 that the tire 3| is so arranged as to engage the floor in whatever position the base member l0 may be.

Due to its diameter and weight, the wheel member 10 forms a substantial base for the support H and maintains the globe and support in an upright position during normal usage. When it is desired to move the globe, the entire support is inclined from the vertical, substantially as illustrated in Fig. 1. The member It] now serves is an elevated one;

a dual function, serving as a counterweight to balance the weight of the globe and yoke, and as a wheel adapted to roll along the floor when a forward force is applied by the person 20. The

.frictional member 3i prevents slipping of the wheel member It, and insures that it will follow the forward course desired by the person moving the globe. In the embodiment illustrated here,

the rotation point between the globe and the wheel member is at the connection between the extension member I2 and the socket M. It may be thus seen that the globe, annulus or yoke may be grasped when the globe is being moved, since all of these parts may be held while the wheel member, support and extension rod rotate with respect thereto.

In the embodiment of this invention illustrated in Figs. 4, 5 and 6, the support I and the extension member l2 do not rotate with respect to the yoke I5 and globe it. The standard II is here shoWn as provided with a handle32 which may be grasped. by the hand'22 when the globe and support are being moved. The base member I5 is, in this embodiment, rotatably mounted with respect to the standard II. This may be accomplished, for example, by providing the base member It with an opening 33 adapted to slidably receive the support I l and by mounting col- .lars 3d and 35 upon the support ll above and below the opening 33.

In this embodim nt the base I 9 is illustrated as having at its edge a rim or socket 3B, which socket is substantially semi-circular in cross section. This socket is adapted to receive a frictional member or rubber tire 3'! having therein a tension member or wire 38, which tension member holds the tire in place in the socket. It will be noted that the edge 39 of the socket does not touch the floor when the base is in its normal position, and that the exterior edge 49 is sufficiently removed from the floor not to contact the same even when the base is inclined at a considerable angle.

It will be thus seen that the tire 31, like that illustrated in Fig. 3, forms a frictional contact with'the floor in any desired position of the base member l9.

The standard of'the support disclosed herein That is, it reaches substantially to, or higher than, the waist of anormal adult, so that when the base of the support is resting on the floor, the globe may be conveniently examined without sitting down or stooping. The base, standard, yoke and annulus are preferably made of metal and thus the entire combination is too heavy to be conveniently picked up and'carried when it is desired to move it from modiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as permissible, in View of the prior art.

What I claim as new, and desire to secure by, Letters Patent, is:

1. A support for a globe, said support being of considerable height and including a heavy base wheel member, rotatably mounted with respect to the globe, said member forming a stationary base for said support when said support is in an upright position and forming a rolling wheel for said support when said support is inclined at a considerable angle.
