V SUSPENDING APPARATUS FOR GEOGRAPHIC GLOBES.

Application filed March 26, 1915.

To all whom it may concern:

Be it known that I, ALBERT S. SMITH, a citizen of the United States, and a resident of New York city, in thecounty of New York and State of New York, have invented certain new and useful Improvements in suspending Apparatus for Geographic Globes, of which the following is a specification.

This invention relates to suspending apparatus for geographic globes.

The principal object of this invention is to provide a suspending device for geographic globes which is simplein construction, and which admits of the ready manipulation and adjustment of the globe.

Further objects and advantages arising from the construction, arrangement, and combination of parts will more fully appear from the following detailed description and the features of novelty will be particularly pointed out in the claims.

In the drawings Figure 1 illustrates a side elevation of my improved suspending means, shown fastened to a wall, and Fig. 2 is a front elevation thereof.

Fig. 3 is a detail view on an enlarged scale of the segment from which the meridian ring is suspended.

-Figs. 4: and 5 are cross sectional views taken respectively along the lines 4% and 5-5 of Fig.3. g g

Referring particularly to the drawings, the suspending device is preferably mounted on a base 10, which may be secured to a wall 11, or any other suitable support. Suitably fastened to the base is a clutch 12 through an aperture of which is inserted a vertical rod 13. An arm 14 extending from the latter is provided with a hook 15 from which is suspended, through connections hereinafter more particularly described, the globe 16.

The rod 13 is normally held rigidly to the base through the action of the clutch12 impelled by the expansion spring 17 which causes the finger pieces 18 to diverge from each other. The clutch also serves as a guide for the rod in its vertical movement and above the clutch is disposed a bracket 19 having an aperture through which the rod passes, and which also serves as a guide for the rod. The vertical rod may be read ily adjusted to difierent positions by grasping a finger piece 20 provided at the lower Specification of Letters Patent.

mounted at its axis the globe 16. Preferably, the distance between the upturned lip 22 of the hook 29. andthe inner overhanging surface 22 thereof is approximately equal to the radial width of the meridian ring. Thus accidental disengagement is avoided. A saddle 24 fastened to the seg ment midway between the hooks and having a pair of shoulders 2 F formed therein which slidably engage the outer periphery of the meridian ring, serves as a guide for the latter when it is rotated within the hooks, and thus further assists to retain the ring properly in position. Indicators 25 dependmg fromthe saddle on each side of the ring are provided for the graduations engraved or molded on the latter. The segment may span an arc of 60 or 90 or more if desired, thus making it possible to swing the globe to any angle up to 45 or more, which is the most that will be found desirable in the practical use of the apparatus.

Upstanding from the saddle is an eye 26, and engaging the latter is a swivel 28, in which is pivoted a swivel hook 29. This hook may engage the hook 15 of the horizontal arm and suspend the globe with its connections therefrom. When so suspended, the globe and ring may be readily manipulated in all directions. Thus, they may be raised or 1 owered by unclamping the vertical rod 13. 'By means of the swivel, they may both be rotated on a vertical axis, the globe being so rotated independently of its own pivotal bearings within the ring.

t may sometimes occur during the adjust ment of the vertical rod that the latter is inadvertently released while the finger pieces 18 are being pressed toward each other. In that event, the rod being free to move would immediately drop so that the arm 14 would strike the bracket 19 with; quite impact.

To avoid this difliculty, a helical spring 27 is provided. about. the rod above the bracket.

When the clutch is released, the arm will strike the spring instead of the bracket and the shock of impact is thus taken up.

It will thus be seen that I have provided a suspending device which is simple in .construction and eflicient in operation, and which admits of the ready manipulation and adjustment of the globe for all purposes desired. Means is provided for raising or lowering the globe to any convenient height, and to guard against shocks occasioned by the inadvertent dropping of the vertical supporting rod suitable cushioning means is provided. Means is also provided whereby the globe and ring may be rotated about a vertical axis so that the rear of the globe and ring may both be readily turned to the front whenever desired.

Having thus describedmy invention, I claim- 1. In a suspending device for globes, a

' graduated meridian ring in which the globe is adapted to bepivotarlly mounted, a segment'having a depending hook at each end provided with an upturned lip, said hooks engaging and securely holding the inner periphery of said ring, a. pointer for the ring locatedupon the segment, and rigid means for suspending said segment and means for vertically adjusting said suspending means.

2. In asuspending device for globes, a graduated meridian ring in whichthe globe is adapted to be pivotally mounted, a segment having a depending hook ateach end integral. therewith, said hooks slidably enga 'ing the inner'periphery of said ring, a saddle fastened to the segment midway be"- tweenthe hooks, said saddle having a pair ofishoulders formed therein which abut the outer periphery of said ringand serve to guide the latter as-it is moved through the hooks, and an engageable portion, and means for suspending'the segment from said engageable :portion.v

'3. In a suspending device for globes, a graduated "meridian ring in which-the globe is adaptedtobepivotally mounted, a segment havinga depending hook' at each end integral therewith, said hooks slidably engagingthe iinner periphery of said ring, a saddle fastened -to the segmentmidway between the hooks, said saddle havinga-pair character described comprising a globe and meridian ring in which said globe is pivotally mounted, means for suspending said ring comprising a base attachable to a wall, a vertically movable rod adapted to be mounted upon said base and guided thereon,

a horizontal arm extending from said rod,

swivel connections between said arm and ring, and means mounted on said base for clamping said rod in its adjusted position.

5. A unitary portable apparatus of the character described comprising a globe and meridian ring in which said globe ispivotally mounted, means for suspending said ring comprising a base,- a vertically movable rod mounted upon said base, a horizontal arm extending from the rod, swivelconnections between said'arm and'ring whereby the globe may be rotated vertically independ ently of'the rod and arm,means mounted on said base for clamping saidrod inits' adjusted position, and means-moimt'ed on :the

rod for-absorbing the shock incident to the inadvertent release of therorl.

16. In a suspending device for globes, a meridian ring in which the globeis mounted, a segment having a depending hook at each end, said hooks engaging the inner periphery of said ring, a bracket, and means whereby said segment is rotatably connected to said bracket, said means comprising a saddle attached to the segment, an eye in tegral with said saddle disposed medially at thetop thereof, aswivel engaging said eye, and a swivel hook pivoted in said swivel.
