GLOBE OR SHADE HOLDER.

SPECIFICATION forming part of Letters Patent No. 759,444, dated May 10, 1904.

Application tied Aprii 24, 190s.

To @ZZ whom, twenty con/cern,.-

Be it known that I, LEMUEL R. Hor'roN, a citizen of the United States, residing at New York, in the county oiE New York, State of New York, have invented certain new and useful Improvements in Globe or Shade Holders, of which the following is a full, clear, and exact description.

My invention relates to improvements in the construction of globe or shade holders, and particularly to a holder adapted to be used with incandescent gas or electric lights.

The object of my invention is to provide a simple and readily adjustable method of securing a globe or shade in position and in such a manner as to do away with the eX- ternal projection of adjusting screws and other like devices. By my invention it is now possible to secure the globe or shade in position by means of adjustable devices situated on the interior of the holder.

The invention will be found to consist in providing a means which is accessible from the interior of the globe for supporting it in a suitable way, so that all the usual expansion of the globe will be provided for without danger of breaking. It will be more clearly seen on inspection of the accompanying drawings, in which- Figure 1 represents a cross-section on the line w m of Fig. 2 and side elevation of an incandescent gas-burner with a globe or shade holder embodying the improvements of my invention. Fig. 2 is a plan view of the holder with then burner-head and adjusting-cap removed. Fig. 3 is a side elevation of an incandescent electric lamp with the holder and shade in cross-section. Fig. 4 is a side elevation of the clamping and adjusting member of the holder shown in Fig. 3. Fig. 5 is a detail perspective view of a clamp which constitutes a part of my invention for holding the end or lip of the globe in place.

1 is the shield for the base oi' the holder which surrounds the stem 2 of the burner shown in Fig. 1, and 3 is the globe or shade which is supported thereby.

4 is the hook-like tip of a clamping mem- Serial No. 154,063. (No medal.)

ber, of which three are preferably provided, as shown particularly in Fig. 2. This clamping member is provided with downturned lugs 5, which oonstitutea satisfactory and practical means for pivoting' the clamp upon the rod G.

7 is a tang carried by the clamping member, which is made so as to act as a spring to normally force the clamp upward and outward about its pivot.

8 is an arm of the clamp which eoacts with the adjusting member 9. This adjusting member9 constitutes in this particular form shown in Fig. 1 a portion ot' the burner. It is adapted to be screwed down upon the basel() of the burner-head for the purpose oi pressing downward upon the arms 8 8 of the clamps, and thus throwing the tips 4 toward the eenter for holding the lip of the globe securely in place. Obviously the pressure of the clamps upon the globe can be adjusted by merely raising or lowering' the adjusting member 9, so as to accommodate slightly-varying' sizes of globes and to hold the globe with sufficient security and yet without danger of breaking.

11 is a cap of the ordinary form, which has a bifurcated supporting-arm 12 for carrying the mantle 13, which latter is shown dotted. To remove the shade, the mantle should be first taken oti:1 by removing the cap 11. The adjusting' member 9 may then be moved to a sufficient extent to allow the spring-tangs 7 7 of the clamp to throw the clamps upward about their pivots, and thus release the lip of the globe. j

The same general construction embodying' my invention is adapted to be used with an incandescent electric light, as shown in Fig'. 8. 14 is a socket member inclosed in the shield 15 and having an incandescent bulb 16. 17 is a collar which is secured by the screw 18 to the socket 14 and provided with a screwthreaded portion 19. 2() is an adjusting-collar corresponding to the adjusting member 9 of Fig. 1. The other parts of this structure,

The operation is effected in asimilar manner by first re' moving the bulb 16 and then adjusting the member 2O as desired.

The invention is therefore of a very simple nature and may be manufactured economically and operated in an efcient manner, while` the outward appearance of the globe and holder is unbroken by the usual adjusting devices.

What I claim is- 1. A globe or shade holder comprising a supporting-shield, a plurality of clamps pivoted on th'e interior thereof and having the ends outside of their pivots adapted to grip the neck of the globe or shade, and an annular adjusting member coacting with the ends of the clamps inside of their pivots for moving the gripping ends 'of the clamps toward the neck of a globe or shade or allowing the same to move away therefrom.

2. A globe or shade holder comprising a stationary shield member, a series of supporting lugs or'clamps on the interior of said shield each other or away from each other for clamping or releasing the base of a globe or shade.

3. A globe or shade holder comprising, a supporting member, a series of spring-pressed clamps mounted on the interior thereof, a stationary base having a screw-threaded portion and an annular adjusting member coacting therewith and alsov adapted to coact with said clamps for the purpose specified.

4. A globe or shade holder comprising, a supporting' member, a series of spring-pressed pivoted clamps on the interior thereof, a stationary base and an annular adjusting member coacting therewith and also adapted to coact with said clamps for adjusting the same.
