'GLOBE-SUPPORTER FOR ELECTRIC LAMPS.
SPECIFICATION forming part of Letters Patent No. 255,212, dated March 21, 1882.
Application filed September 7, 1881. (No model.)
To all whom it may concern.-
Be it known that we, JOHN TREGONING and LEWIS H. LATIMER, residing respectively in the cities of Philadelphia, county of Philadelphia, and State of Pennsylvania, and New York, in the county and State of New York, have inventedcertain new and useful Improvements in Globe or Shade Supporters for Electric Lamps, of which the following is a speci- 1O fication.
It has been usual heretofore in electric lamps-such as arc-lamps, which have open glass globes or shades-to hold the globe in place upon the lower cross-bar of the lamp by means of globe supporting and fastening'devices applied to that part of the lamp. This mode of holding the globe is objectionable and inconvenient on several accounts, principally because with this arrangement it is neces- 2o sary to remove the globe for the insertion of fresh carbons, and because the shade or globe, when rigidly held, is liable to be broken by jars and to swing the lamp when exposed to the wind. Under our improvement we suspend the globe by its upper end, making use for this purpose of a holder or supporter which extends across, between, and is adjustably fastened to the side rods of the lamp, so that it may be moved up and down thereon, and 1a is provided with spring closingclampsoryokes, which fit tightly around and clasp between them the neck or upper end of the globe. The latter is to be formed with a flange or outward swell or projection abovethe point where the 5 yokes clasp it, said flange or projection forming a shoulder, which will prevent the globe from dropping down out of the grasp of the yokes.
The nature of our improvement, and the manner in which the same is or may be carried into elfect, will be understood by reference to the accompanying drawings, which represent the preferred embodiment of our invention.
Figure 1 is a front elevation of so much of an electric lamp as needed to illustrate the improvement.
Fig. 2 is a plan; and Fig. 3is
an elevation, on enlarged scale, ofthe globe supporter or holder.
A is a cross-bar, formed at its center so as not to impede or interfere with the passage of the upper carbon, a, of the lamp. In the present instance it is formed for the purpose with a central ring,rB. At each end of the cross-barA is a splitspring-sleeve,D, provided with ears, through which passes the clampscrewE. These sleeves fitupon the side rods,
1), of the lamp, and are held tightly thereon in any required position by means of the clampscrews. When the screws are loosened the bar can be moved up or down on the rods 11,
as desired. Upon the cross-bar, on each side of the central ring, B, are mounted sliding sleeves 0, provided with curved jaws or yokes 0, between which the globe is clasped. The yokes are pressed inwardly or toward one another by means of springs suitably arranged. The springs in this instance are spiral springs,
F, confined between the outer end of each sleeve and a shoulder on the outer end of the bar A.
The globe G is clasped at its upperend with yielding pressure between the yolges 0, and, as shown in Fig. 1, is provided with a flange,
0, or its equivalent, forming ashoulder, which will rest on top of the yokes, so as to prevent the globe from dropping down away irom them.
The device constitutes an efficient globeholder. It is convenient, and open to none of the objections which attach to the kind of holder heretofore ordinarily employed.
What we claim, and desire to secure by Letters Patent, is-
1. Aglobe or shade holder for electric lamps, consisting of a cross-bar or frame formed to permit the passage of the carbon or carbons, and provided with end clasps, by which it may be adjustably fastened to the side rods of the lamp,incombination with spring closingyokes 0 or jaws, which receive and clasp between them the globe, substantially as hereinbefore set forth. 4
2. The cross-bar provided with central ring and end split spring sleeve and clampingscrews, in combination with the globe-holding jaws or yokes mounted on said bar, and the jaw or yoke actuating springs, under the ar- 5 rangement and for operation as shown and described.
3. The combination, substantially as hereinbefore set forth, of the side rods of the electric lamp, the globe-holder atljnstably connected 10 with and supported by said side rods, and the I globe carried by and suspended from said globe-holder.
In testimony whereof we havehereunto affixed our signatures this 22d day of August, 1881.
