HERBERT O. TOMLIIVSON, 0F WHEATON, ILLINOIS.

SEMI-INDIREGT-LIGHTING DEVICE.

Specification of Letters Patent.

Patented June 21, 1921.

i Application le. September 12 1919. Serial No. 323,254-,

To all 107mm it may concern Be it known that I, HERBERT O. TOMLIN- soN a citizen of the United States, residing at li/Vheaton, State of Illinois, have invented a new and useful Improvement in Semi -Indirect- Lighting Devices, of which the following is a specication.

This invention relates generally to electric-light fixtures and has for its object the provision of a fixture including a support or holder for an electric-light diffusing bowl or globe, which is simple in construction and ornamental in use.

Another object is to provide a fixture of this character with a holder which shall be largely concealed from view below and which shall effectively support the light diffusing bowl in a manner to afford ready removal of suoli bowl from the fixture without the disengagement of the holder from the shade.

With these and other objects in view, my invention consists in the novel construction, combination, and relative position of the parts Vand members hereinafter described and shown in the accompanying drawings, and particularly pointed out in the appended claims.

A structure embodying my invention is illustrated in the accompanying drawings, in which Figure 1, is an elevation showing Figs. 2 and 3 are respectively, side elevation and plan view of my improved bowl holder, and Fig. l isan enlarged detail in sectional view showing the attachment of the holder to the edge of the shade or reflector.

Referring to the illustrations, 10 indicates an incandescent electric lamp which is carried in the well known socket 11. A reflector or shade support 12, comprising a split ring 12A encircling the socket 11 and having a binding screw 13 for clamping the ringl to the socket, is provided with thecutstanding annular flange 12D with radially arranged screws 14C for releasablyr engaging the annular iiange 15A of the shade or reflector 15, which preferably is of white or opal glass. In this way the reiiector 1s removable by downward disconnectlon from said supporting means therefor. i I have preferred to show the reflector 15 of a iiat downwardly flaring form.

The `diffusing bowl 16, is preferably o translucent ground glass and may be of any in the county of Dupage and v suitable shape or color. 16A is formed bowl.

To supportthe bowl 1G below the refiector 15, I provide a support 17 which comprises preferably three downwardly diverging spring-like metal arms 17A which areVV provided with hooked-ends 17B adapted to engage any points on the flange 16A to retain the bowl. The bowl is rotatable, of course, 1n these hooks, so that it can be insertedl and removed in of. Near their upper ends 17C the arms V17A are held in spaced relation by a ring 17D which is welded, or in any'other way. attached -to the arms. d formed in a compound curve, and are outwardly disposed in a manner to y aiiord spring-like hooks which engage over the upper edge 'of the reflector and thus support the bowl therefro It will be observed that the holder need not be disengaged from the reflector to permit the removal ofthe-bowl, but that it is only required that one of the spring-arms 17A be unhooked from thebowl iiange to permit the bowl to be readily removed from the other two supporting arms. Also, by reason of the fastening' means 13 the reiiector and bowl and the supporting means therefor may be removed intact from the lower end of the socket. will be seen, permits the ring 12A to be removed from the lower end of the socket, even when the lamp is in place, and if this is; done the lamp can then be unscrewed, very obviously, after such removal of the bowl and reflector as a unit from the lower end of the socket.

It will be seen that the rigid ring 17D fits snugly within the opening in the upper portion of the reiiector 15, so that the upper end portions 17E of the spring-y arms overhang the edge of said opening, whereby the bowl is firmly supported below the reflector. These springy upper end portions 17E a-re sprimg inwardlyl when forced upwardly A suitable flange -through the opening in the reflector while the lower end portions 17B` are sprung outwardly to receive the annular upper edge of the bowl. Thus the bowl support is resiliently engageable with and detachable from the upper and inner edge of the reflector and is also resiliently engageable with and detachable from the rim or upper edge of the bowl, but the' rigid ring 17D holds the aroundthe upper edge` of the The lamp 10, it`
