EDWIN E. FREDERICK. OF BRIDGEVILLE BOROUGH, PENNSYLVANIA.
Application filed December 31, 1912.
0 all whom it may concern lie it known that I, EDWIN E. l nnnnuicir, a citizen of the l nitcd States, and residing in the borough of Bridgcville, in the county of Allegheny and State (it Pennsylvania. have invented or discovered new and useful Improvements in Globe-Holders, of which the following is a specification.
My invention consists of a new and iinproved spring holder for globes, shades and similar articles, and it i especially intended for use in connection with depending lighting fixtures, such as inverted incandescent gas lights. i The objects in view are to facilitate the installation or removal of the globe, to properly center the same in relation to the tin ture, and to prevent its accidental dislodgin nt.
In the accompanying drawings, Figure l is an elevation showins my invention applied to an inverted incandescent gas fixture; Fig. 2 is a section of the same along the line H It in Fig. 1 looking in the direction ot the arrow and showing the spring clamp in its normal or contracted position assumed in holding the globe; Fig. 8 is a similar view showing the said spring clamp expanded to permit the insertion or removal of the globe; F 4 is a perspective showing the spring clamp I'Gll'lOVOtl from the canopy; Fig. is a view similar to Fig. 2 showing av slight modification, and Fig. 6 is a view similar to Fig. 3 showing the same n'imlitication.
The following is a detailed description of the drawings.
A is an inverted incandescent gas lighttiXture wherein 1 is the gas check, 2 the mantle support, and 3 the depending canopy from which the globe is to be suspended. Said canopy is usually stamped of sheet brass or other suitable material and is provided with a depending annular flange 4.
5 are the ports in said canopy tor the escape of the products of combustion. The spring clamp member B is mounted in said flange The member B is formed by bending up into annular form a length of resilient wire or similar material having its end portions 6 and 7 overlapping. The extreme ends 8 and 9, respectively, are bent outwardly at an angle. The end portion 6 lies in the arc of the circle described by the body of the member B, while the end portion 7 lies in an arc of larger radius, as shown in Fig. 4. Inten fipecification of Letters Patent.

Serial No. 739,473.
mediate of its ends the annulus B is provided with an integral radial loop 10 whose end is preferably upturned as at ll.
ln mounting the clamp member 13 in the flange l, the loop 1.0 is inserted hrough a slot 12 in tlange 4', the upturned portion 11 of id loop preventing its accidental withdrawal. The end S is inserted through a slot 13 and the end 9 is inserted through a hole M.
15 and 10 are knobs fixed on the ends 8 and 9, respectively, forming a convenient means for operating the clamp and preventing the accidental withdrawal of the ends from the flange 4.
lihen the clamp B is in its contracted or gripping position shown in Fig. 2, the loop 10 tends to bear against one end of the slot. 12 and the end 8 tends to bear against the C(lllQSPC-lldlllg end of slot 13, thus controlling the contraction of the member B. hen said member is expanded to the form shown in Fig. 3, the loop 10 and end 8 bear against the other ends of their slots, thus lin'iiting the expansion of the member B. The end 9 is held in position at all times in its hole 14.
The member 1% may be expanded by press ing the knob toward the knob 16, the latter being used for leverage. By this means the end 8 and loop 10 are caused to slide in their respective slots, pern'iitting the member B to expand and at the same time maintain its annular form. Thus the neck of the globe may be inserted into or withdrawn from the clamp without tilting. \Vhen the knob 15 is released, the member B contracts to its normal diameter, as shown in Figs. 2- and 4, still maintaining its annular form and resiliently yet snugly gripping the neck of the globe throughout substantially its entire circui'nference. Thus the globe is held snugly against rattling. lVithout the provision of lateral movement of loop 10 such functions could not be performed. The clamp would not at all times maintain the form of an annulus and the globe would be tilted to insert or remove it, and the grip of the resilient clamp would be interrupted. By maintaining the member B in the form of a true annulus, having its center substantially coinciding with the center of the canopy 3, the globe is properly centered and presents an attractive appearance.
In the modification shown in Figs. 5 and 6. the annulus is provided With two loops 10, instead of but one loop, seated in a like number of prolonged slots 12. The operation and function of the spring clamp B is the same as above described."
The holder is neat, inexpensive yet containing no parts likely to be broken or Wear out, and is convenient and etficient in the installation, removal and support of the globe.
Vvhat- I desire to claim is In a globe-holder, an annular flange provided with slots, a resilient Wire bent into an annulus with overlapping and outwardbent ends, one of said ends being projected through said flange, a knob secured to said projecting end and holding the same against movement, the other of said ends extendingthrough and being slidable in one of said slots, said last-inentimied end being mow able in its slot toward said first. end to expand the annulus and a radial loop formed in the intermediate portion of said annulus and extending through the other of said slots, said loop moving laterally in its slot toward the movable end of said annulus when the latter is expanded and moving in its slot toward the fixed end When said annulus contracts to its normal diameter, whereby said annulus expands and contracts uniformly.
Signed at Pittsburgh, Penna. this 30th day of December 1912.
