.. LAMP. LAMP SHADE, AND LAMP SHADE HOLDER Filed May 17, 1943 INVENTOR Mm y ATTORNEY@ Patented Oct. 30, 1945 UNITED STATES PATENT OFFICE LDER David J. Ross, Benton Harbor,Y Mich.
Application May 17, 1943, Serial No. 487,203
2 Claims.
The main objects of this invention are:
First, to provide an improved lamp including a lamp shade holder which is highly efficient in supporting the lamp shade in proper` relation to the lamp.
Second, to provide a lamp shade which is capable of adaptation to lamps of the upright socket type as well as to lamps of the inverted socket type.
Third, to provide a lamp shade holder which may be applied to a lamp socket of standard types in a very secure and eective manner for proper supporting of the shade.
Fourth, to provide a structure having these advantages which may be economically formed of re resistant fibrous material and which is very attractive in appearance.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.
'Preferred embodiments of the invention are illustrated in the accompanying drawing, in which:
Fig. 1 is a fragmentary side elevation of a lamp embodying the features of my invention, the shade and holder being shown partially broken away and partially in vertical section.
Fig. 2 is a plan View of a desirable design of one of the shade holders.
Fig. 3 is an enlarged fragmentary vertical section showing certain of the structural details.
' Fig. 4 is a fragmentary view illustrating the adaptation of my shade and shade holder to a lamp having an inverted socket.
Fig. 5 is a fragmentary View of a modied form of shade structure.
In the embodiment of my invention illustrated, I represents the lamp standard, 2 the upright socket, and 3 the lamp bulb threaded into the socket.
The lamp socket is formed with external threads 4, these commonly resulting from the forming of the internal threads to receive the lamp.
The skirt or wall portion 5 of the shade may be of parchment or other suitable material and the structure shown is conical and provided with trimming 6 at the top and bottom. This of course is optional and the wall may be provided with any suitable design.
The lamp shade holder designated generally by the numeral 1 is formed of a brous, preferably nre-resisting, material, the product commercially known as Masonite being an example of a material which I have found satisfactory. This disk is died or stamped out to provide an annular rim portion 8, a central hub portion S with connecting spider portions IIJ. The hub portion has a central opening II therein adapted to receive the'socket 2.
The holder is of substantial thickness and the opening II is of such diameter that the holder may be arranged on the socket and rotatably forced downwardly thereon with a result that the threads of the socket form threads in the holder and a very secure engagement is provided and one which prevents accidental disengagement of the holder and also tilting of the holder on the socket.
The lamp shade walls are preferably provided with a supporting member I2 at the top thereof which is adhesively secured as indicated at I3 within the shade wall adjacent the top thereof. This may consist merely of an annular ring I1 as shown in Fig. 5 or it may be provided with the hub portion I5 as shown in Fig. 1 having a central opening I6 therein corresponding to the opening I I in the shade holder 'I so that this upper member I2 may be secured upon the threaded socket of an inverted lamp in the same manner as described for the holder 'I and as is illustrated in Fig. 4. In that case, the holder 'l would not be used and this holder is not secured within the lamp shade. It is adapted for use on shades varying somewhat in size and shape and effectively holds them against tilting or canting on the holder. A further advantage is that the shades and their holders may be shipped or packed in the knockdown or separated in which condition the shades may be nested.
My lamp shade and shade holders may be formed without the use of metals-that is, entirely formed of fibrous material, may be very economically produced, and at the same time are highly ecient for the purpose, and attractive in appearance.
I have illustrated certain practical commercial embodiments of my invention but have not illustrated other adaptations or embodiments which I contemplate, as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a lamp, the combination with a lamp standard provided with an externally threaded lamp socket, of a lamp shade holder formed of a disk of re resistant fibrous material of substantial thickness and comprising an annular rim portion, a central hub portion having an opening therein, and a spider portion, said opening being adapted to receive said socket and to be rotatably engaged with the threads thereof, and a shade sleeved over said holder, said shade being provided with an annular reinforcing member of re resistant fibrous material fitted Within and adhesively secured thereto adjacent its upper end, said shade being separate from said disk and of frustrum shape to permit a plurality of shades being packed in nested relation separate from the disks for shipping and to permit a shade to Wedgingly engage a disk when the lamp is assembled, said shade being of the greatest diameter at the lower end thereof, said disk supportingly engaging the shade adjacent the lower larger end thereof.
2. In a lamp, the combination with a lamp standard provided with a lamp socket, of a lamp shade holder formed of a disk of iire resistant fibrous material and comprising a rim portion, a central hub portion having an opening therein, and a spider portion, said opening being adapted to receive said socket, and a shade embracing said holder, said shade being provided with an annular reinforcing member of re resistant fibrous material tted within and adhesively secured thereto adjacent its upper end, said shade being of progressively increasing diameter from the upper to the lower end thereof, said shade holder supportingly engaging the shade in the lower larger end thereof.
