JACOB B. BANDER, OF NEW YORK, N. Y.

SHADE HOLDER FOR.ELECTRIC-LIGHT FIXTURES.

Application filed October 8,1924. Serial No. 742,284.

To all whom it may concern:

Be it known that I, JACOB B. BANDER, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Shade Holders for Electric-Light Fixtures, of

which the following is a specification.

This invention relates generally to lighting fixtures, having more particular reference to a shade holder intended more especially for use in connection with electric lamps.

The invention has for anobject to provide a novel and improved shade holder that will securely hold the shade,and that does away with the use of screws, and facilitates the application and removal of the shade, decreasing the likelihood of breaking of the shade at these times.

.For further comprehension of the inven tion, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth. a

Fig. 1 of the drawing is a side view showing an electric light fixture having the shade thereof attached by my improved means.

Fig. 2 is a central vertical sectional View of the holder, the socket casing of the fixture being shown partly in elevation.

Fig. 3 is a fragmentary side View with parts broken away.

Fig. 4 is an underside plan view of the holder.

Fig. 5 is a fragmentary vertical sectional view taken on the line 55 of Fig. 3.

Fig. 6 is a fragmentary vertical sectional view showing a modification.

Fig. 7 is an underside plan view of the device shown in Fig. 6. y

In the drawing the reference numeral 10 indicates an ordinary cylindrical casing or covering for an electric light socket, a portion of the socket being indicated at 11. This casing is of generally cylindrical form with a semi-spherical upper end 10 and is suspended from the lower end of a chain 12 in the usual manner, the upper end of the chain being attached to an ordinary ceiling device 13. My improved shade supporting element is formed in twov sections, and comprises an upper portion that snugly encloses the casing, and a lower outwardly flared portion or skirt, being diametrically split from top to bottom to form the two sections. The top portion of each section is numbered 16 and the bottom portion or skirt is numbered 17. These sections are pivotally attached to the casing 10, adjacent the bottom of the latter, and adjacent the side edges of the sections, as indicated at 18/ The lower or skirt portion 17 of each section is formed to present an arcuate depending flange 20, the two flanges forming a neck element that fits, snugly in the usual opening in the top of the shade 21. From the bottom of each of the flanges 17 a segmental lip 22 projects radially, that is horizontally outward, this lip diminishing in width from the central portion'of each of I the flanges toward the ends of the latter, as clearly shown'in Fig. 4 of the drawing. The various parts are so proportioned that when the top portion of the holder is closely engaged over the casing 10 the neck formed by the flange 20 fits'snugly in the opening in the shade, with the lips 22 proecting under the opposite edges of said' opening to support the shade, the ends of the flangesbeing separated from one another in this position to permit of the two sections.

of theholder swinging on their pivotal axes sufliciently to contract the skirtportion of the holder toallow of its insertion in or reshade. As will be apparent, when the shade is held in one hand around lip 22 and the shell 25 is lowered, sections 16 will be cammed into closed position. When this shell is in position on the holder itacts to retain the two sections of the latter in opera 'tive position. In order to prevent either one of the sections of the holder swinging too far when the shell 25 is removed I provide an abutment stop that is located between the said sections below. their pivotalaxes and is here in the form of a hooked member 28 secured to the casing 10.

In the modification shown in Figs. 6 and v7 this abutment is in the form of abent wire 30 whose ends pass freelythrough holes.

in the holder sections to pivotally support the latter. These wire ends pass also through V horizontal slots such as 31 in the casing 10 and have disk heads 32 fixed thereon. As

I shown in these figures also, the flanges 22 on the holder sections have pivotally mounted on their bottom faces'as at 34 the triangular arms 35 that are adapted to be engaged by pins 36 fixed to and depending from the shell 25, these pins passing through arcuate slots 37 in the shell. By partially rotating the shell, after it has been lowered, the arms 35 may be moved to biiid on the shade. The bent wire 30 thus holds the holder sections yieldably apart at their lower ends andprevents, by such yielding, any excess stress on the glass ware' or shade.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as i a I V 'lgIn combination inner member for'min'gflacovering adapted to; fit on an ele t i ht se ke P fair f pping members pivoted each at an individual pair of oppositely disposed alined points to the lower endof the inner member, and a shell engaging the shade gripping members and retainingthem in the shade gripping position, said shade gripping members comprising portions normally covering the top 'o fjthe'inner member and outwardly flared lower portions.

2. A shade holder comprising a pair of shade gripping members adapted to be pivotally mounted on light fixture, and a shell engaging said members and retaining them in operativepositions, said shell engaging said members by 'longiti'idinal sliding movement and havlng a lower edge cooperating wlth the shade gripping members to hold a shade, said memberscomprising semi-cylindrical top portions and outwardly flared lower portions, said lower portions being provided with radially projected flanges on which the shade rests.

3. A shadeholder comprising a light fixture of cylindrical form, a pair of shade gripping members, comprising semi-cylindrical upper portion fitting over said light fixture, and outwardly flared lower portions engaging the shade, said members being pivotally attached to the said fixture adjacent the lower ends of their top portions, a shell surrounding said members and retaining the latter in operative position, and

an abutment stop attached to said fixture outwardly flared loWer portions, said lower portions being provided with radially projected flanges on which the shade rests, triangular arms pivoted on said flanges,

and pins carried by said shell and adapted to engage said arms to project the latter into gripping relation to the shade.

In testimony whereof I have afiixed signature.

JACOB B. BANDER.
