SHADE HOLDER FGR ELECTRIC-LIGHT FIXTURES Application filed. February 6, 1925. Serial No. 7,318.

tion is to provide an improved device of this kind which may be used either for closed or open glassware such as globes or bellshaped shades.

A third important object of the invention is to provide a device of this character having novel construction by means of'which the device may be made to support the lamp shade wlthout the use of screws bearing against the shade and without screwing any of the parts together.

A fourth important object of the invention is to provide a device of this character having a novel arrangement of tilting arms and fingers supported on the main part of the device in an improved manner, the support itself limiting the tilting movement of such arms andfingers.

A fifth important object of the invention is to provide a novel stop arrangement for the tilting arms and fingers which will also act as a stop for the means employed. to retain the lingers in their expanded or spread position.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed. 1

In the accompanying drawings like char: acters of reference indicate like partsin the several views, and:

fingers are tilted.

Figure 6 is an enlarged detail vertical section showing the manner in which the combined support and stop acts when the Figure 7 .'s a detail section showing a certain spring for retaining the bell in position. I

In the present embodiment the invention consists of three general parts, an inner shell, arms tiltably connected to the inner shell and a bell having a portion arranged to force the arms against the inner shell andhold them in such position, the arms carry fingers which are expanded when the arms are against the inner shell and collapsed when the arms move outward,

In thedrawings there is disclosed an in nershell 10 having its upper edge curved inwardly to form a top portion 11 provide-d with a central opening 12 wherethrough may pass shank 13 of a socket 14L, stop for holding an incandescent lamp 15. Fitted over this inner shell 10 is a series of arms 16 each of which has its upper end curved inward as at 17 to fit over the curved portion 11 of the inner shell and which butts against a shoulder 18 at the top of the inner shell, the outer surface of the arm at this point being flush with the upper edge of the shoulder. Each ofthese arms carries on its lower end an outwardly and downwardly projecting finger 19 having a portion adjacent its extremity bent downward as at 20Iand its bent outward extremity as at 21, the parts 20 and 21 thus forming a shoulder so that a shade or globe 22 having the usual top. opening 23 may reston the parts 21 and be held centrally positioned by the parts 20. In order to expand each of these arms and its finger there is provided for each arm a lower supporting tongue 24 turned upward and inclined outwardly as at 25 at its extremity. There is also provided an upper supporting tongue 26 having an upwardly and outwardly inclined extremity27. These tongues are struck out of the body of the shell 10 ad jacent its lower end and this construction can best be seen by reference to Figure 6. Each tongue passes through a suitable opening 28 in the respective arm and by reference to the said figure it will be seen that the upturned portions 25 and '27 of the tongues form limit stops" for limiting the outward tilting of the arm 16. At 29 is a bell having a contracted end 30 which slidably fits over the arms 16 and draws them together ithllSSUED tv'ith n inner area adapted ,torecfe f ami as shown in Figure 4. This, of course, expands the group of fingers 19 so that while the parts, in the position of Figure 3, are

so arranged that the group of arms may pass through the shade opening 23, yet, when the bell is applied, these fingers are so expanded as to grip beneath the shade 22 on its inner or under side. It will be noted from Figure t that parts 27 also form limitstops for preventing the bell from passing down too far. The bell preferably has a depending skirt 31 which rests on top of the shade 22 adjacent the opening 23 and thus holds the shade against moving loosely on the arms. spring catch is used to prevent the bell from accidentally slipping upward.

In use the spring catch is pushed-in and the bell drawn up to free the arms 16' The fingersare then inserted into the opening 23 of the shade and the bell pushed down over the arms thus securing the shade in position. Now, there has been here shown threeof the arms 1.6,but it is clearly to be understood that the invention is not limited to the use of three arms. For instance, with heavy shades, a larger number of arms is preferable and in certain instances six or even eight arms may be found desirable. It is deemed unnecessary to show these various numbers of arms as the construction on which the invention is based will remain the samein each case.

In order to make certain that the wings open properly a spring 33 is provided. This may either be a leaf spring such as is shown in Figure 6 or it may be a coil spring wound around the member 26. v

Furthermore, it is to be noted at the bottom of the skirt 31 a bead 32 is preferably provided on which may rest a suitable reflector 33, the device being thus capable not only of being used to support a hell or globe shaped shade but also to support any desired type of reflec-tor. i

It will also be observed that this, head may be used to support an ornamental band or; hood. t

There has thus been provided a simple and eflicient device of the kind described and for the purpose specified. A

It is obvious that minor changes may be made in the form and construction "of theinvention without departing froni the spirit thereof. It is not, therefore, desired tocbnfine the invention tov the exact form herein shown and described, but it is desired to include all such as properly come within thescope claimed.

Having thus described the invention, what is claimed asnew, H A p ,1,- In 'a shade support, the combination lighting fixture and havin a cylindrical body eta. series prams arcuat'e in cros's section and surrounding said shell, means on the lower end of said shell to support the lower parts of said arms for swinging movement of the upper ends of the arms to and from thesh-ell, each of said means being provided with a limit stop engaging the outer surface of the respective arm to limit the outward movement of its upper end, said means each including a tongue extending rigidly and radially from the shell through the lower part of the respective arm and having an upturned extremity to engage the outer surface of said arm, other limit means above the last mentioned means and each including a similar but longer tongue extending through the respective arm above the first means and provided with a similar upturned extremity, a finger on the lower end of each arm extending radially from the shell, said fingers being arranged to support a lamp shade at their extremities, and a bell slidable over said arms to hold them against the shell and the fingers expanded.
