YOKE FOR GLOBE SUSPENSION.

To all whom tt may concern:

Be it known that I, THOMAS H. COSTELLO, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Yokes for Globe Suspension, of which the following is a specification.

My invention relates to globes of a suspended type and the Object thereof is to provide a simple, cheap and efficient device for suspending the same that can readily be adjusted or removed and that is not likely to receive injury in use.

My device ermits ready adjustment of the globe. It argely does away with frictional resistance and prevents any tendency of the parts to bind upon each other. It is also so constructedas to reduce the parts to a minimum and enables the principal parts to be made in duplicate and by a limited number of operations.

The principles of my invention are illustrated in the drawing in which- Figure 1 represents a front elevation of the portion of the globe meridian ring with my device atached thereto. Fig. 2 is a top view of the same. Fig. 3 is a cross section on the line 3-3 of Fig. 1. Fig. 4 is a front view and Fig. 5 a cross section of a modification of the device. Fig. 6 is a front view and Fig. 7 a cross section of another modification thereof.

Further describing my invention, with reference to the drawings in which like characters of reference denote like parts throughout; 1 represents the support comprising a double faced piece 4 and rear piece 5. Both of said pieces or members 4o may be stamped from sheet metal and be of recisely the same construction. Each may e provided with hooks for suspension 6, indicator 7 and members 8 which should be so formed by a subsequent operation as to ass around and engage beneath the ring anges 2 and 3. The parts 4 and 5 being thus identical in construction may be placed on either side of the ring and when secured together by the bolts 10 will provide a symmetrical, complete and balanced support by which the ring may be suspended. The indeX fingers 7 should be properly offset to pass around the flanges of the ring. They may also be made a means, as shown in -Figs. 4 and 5, by which anti-friction de- Speccaton of Letters Patent.

vices, such as the rollers 12, may be placed beneath the meridian ring flanges.

It will be seen that parts 4 and 5 are exact duplicatesl of each other so that they can both be made by the same cutting and formino' dies. Any two pieces which have been siilojected to the complete sequence of operations can be placed 1n reversed position to each other and when fastened together, as by the bolts 10, form a con'lpletol structure. The members 8 may be formed in dies so as to embrace the ring flanges and bear directly on the underside` thereof. It is difficult, however, to form the inwardly projecting ends of the members 8 to an exact right angle corresponding to the underside of the ring flanges. A completely non-binding device may be had by providing the downwardly projecting members on the lower edge of the yoke pieces 4 and 5 with anti-friction devices as shown in Figs. 6 and 7, whereby the members 8, instead of being curved to be engaged beneath the flanges of the meridian rlng are carried outwardly and downwardly and have antifriction rollers 15 mounted thereupon. In this case the weight of the globe and ring is carried entirely at the ends of the yoke while in the modification last described, the weight of the globe and ring is carried at the center of the yoke, while the members 8 act as guides therefor.

I claim:

1. In a globe suspending device; the combination with a double faced meridian of a yoke comprisin a plurality of independent duplicate mem ers each of said members having an elongated body portion provided at each end thereof with devices to engage under the flange of said meridian, said 95 members being disposed substantially parallel to the meridian and provided with means to secure them together to form the` yoke and attach it to the meridian.

2. In a globe suspending device; a yoke consisting of two independent substantially duplicate elongated members, and means for securing said members together, eacli of said members comprising a body portion and means on the same edge but at opposite ends thereof for engagement under the flanffe of a globe meridian on the side of the meridian adjacent to the said member.

3. In a globe suspendin device; a yoke consisting of two indepen ent substantially 110 duplicate elongated members, and means for securing said members together each of said members being provided at each end thereof but on the same edge with'integrally formed means for engagement under the flange of a globe meridian on the side of the meridian adjacent tothe said member.

4l. In a globe suspending device; the combination with a flanged meridian, of a yoke having an elongated body portion disposed substantially parallel to the said meridian, devices on each end of the yoke and spaced kfrom each other by the body portion thereof to engage the said meridian and act as guides therefor; and a supporting means placed midway of the said guides to engage under the meridian flange.

5. In a globe suspending'- device; the combination with a lianged meridian, of a yoke having an elongated body portion disposed substantially parallel to the said meridian, devices on each end of said yoke spaced from each other by the body portion thereof and adapted to engage the said ring and act as guides therefor, a supporting means carried by said yoke midway of the said guides,

and an anti-friction device carried by said support to engage under the meridian flange.

6. A globe suspending yoke consisting of two elongated body members substantially identical in outline provided with suspending means and with ring engaging means offset from the ends of said body members, whereby when said members are reversed and secured togethera symmetrical structure is produced.

7. As a new article of manufacture, a globe yoke member having an elongated body portion and meridian flange engaging devices on the same edge of the lmember but at opposite ends thereof, said member being adapted when applied to a Vduplicate thereof in reverse position and secured thereto to form a symmetrical supporting yoke for a double faced globe meridian.

In witness whereof, I have hereunto set my hand at Chicago, Illinois, this 3rd day of June 1908.
