FREDERICK J OHN GOULD, OF LONDON, AND EDWARD SMALLVVOOD STAMP, OF BIBT/LING-I-IADT, ENG-LAND.
SHADE-SUPPORT FOR GAS-BURNERS AND ELECTRIC LIGHTS.
Application filed Gctober 30, 1915.
1/ b all whom. it may concern:
Be it known that we, Fnnonnion Jenn Germ), resident of 29 Little Trinity Lane, London E. G. 4:, England, and EDWARD SirALL-wooo STAMP, resident of Gothic Works, King Edwards Road, Birmingham, England, both citizens of the United Kingdom of Great Britain and Ireland, have invented certain new and useful Improvements in or Relating to Shade-Supports for Gas-Burners and Electric Lights, of which the following is a specification, such as will enable others skilled in the art to which it appertains to n sire and use the same.
This invention relates to a shade or reflector for and electric lights of the kind which are capable of being moved around an imaginary center or on pivots so as to shade the light more or less as required in v practically any direction or to reflect the light in almost any direction.
The chief features of the invention are the employment of a slotted part-spherical body or equivalent and pivots on the shade adapted to fit into the slots with means for holding the shade when it has been tilted on the pivots to the required angle.
We will describe the invention more particularly as applied to an inverted incandescent burner and it will be evident that by suitable construction of parts it can be applied to an electric lamp.
The burner nozzle, pipe, needle valve. etc, may be of any usual or convenient kind. but instead of usi. a gallery or like shade support we employ a hollow preferably spherical body in which are slots or other lilre openings. preferably vertical slots, arranged in pairs each member of which. is diametrically opposite its fellow. The shade or reflector is furnished with a central opening rather larger than the diameter of the said body and at each of two opposite points we a rim-urn a pin. these two pins are adapted to enter the slots in the body and to thereby support the shade in pivot-like manner. At any convenient part of the shade, preferably close to the opening therein, and say about centrally between the pins we furnish a screw or other suitable device which will engage the spherical body in such a manner that when the shade is turned on the pins, and is therefore tilted, it can, by tUIIllfO-fi' the screw or otherwise manipulating the device, be held in the tilted position.
Specification of Letters Patent.
Patented Apr. 13, 1920.
Serial No. 260,410.
lVe will now describe our invention with reference to the accompanying drawings in which it is shown applied to an inverted incandescent gas burner.
Figure 1 illustrates the burner with the shade fixed horizontally, a position it would assume if not intentionally set at another angle. The same drawing illustrates by line and dot the shade in a tilted position.
Fig. 2 is a plan view of the burner and shade shown in Fig. 1 as seen from the top thereof.
in these drawings the spherical body ahaving an open end Z) is shown of sheet metal or other suitable material, in which are slots 0 which have fellow slots on the opposite side. The shade (Z is provided with pins 6 adapted to engage in the slots 0 and to support the shade on the body a. small plate 7 carrying a finger screw 9 is fixed to the shade in such a position that the end of the screw can be caused to press upon the body a so that when the shade is tilted and the said screw turned to closely contact with the body it will hold the shade in any position to which it may be moved.
In the construction shown more particularly with reference to Fig. 1, it will be observed that two slots 0' are provided and are of greater length than the slots 0. The object of these slots is to permit the shade being put onto and taken off the body. the removal being effected by raising the shade from the position shown so as to free the pins 6 from the slots 0, after which it is slightly turned so as to bring the pins into the slots 0 along which they can travel downwardly and pass entirely out of the slots on the underside of the burner.
The method of permitting the removal and attachment of the shade is an example only of the way in which such removal and adjustment can be effected, and it will be obvious that other means, such for example as making the pins in the form of screws to travel radially in relation to the center of the shade, can be adopted. In the construction shown, the upper part of the body is formed with an air regulator it fitted with an inner sleeve 2' adjustable by means of screw j working in slot is. This air regulator may be separate from or integral with the body a.
We have referred to the body as being made of sheet metal but it may be of othe;
material and while a spherical shape is preferred, it is not essential that this shape be adhered to for example, the upper part might be conical or flat sided of conical section and while we prefer the form of regulator shown it must be understood that any other convenient kind may be employed.
\Vhat we claim and desire to secure by Letters Patent is 1. In a light shade, the combination of a shade holder; a hollow substantially spherical member having slots whereby said member is attached to said holder; a conoidal reflector having an opening to receive said spherical member; trunnions on said conoidal reflector disposed diametrically opposite each other and adjacent said opening, said trunnions being adapted to extend into slots in the spherical member whereby the reflector is connected therewith to be adjusted thereon; and a clamp on said conoidal reflector adapted to engage the spherical member to hold the reflector in adjusted position thereon.
2. In a light shade, the combination of a shade holder; a hollow substantially spherical member having slots whereby said mem ber is attached to said holder; a oonoidal reflector having an opening to receive said spherical member; trunnions on said conoidal reflector disposed diametrically opposite each other and adjacent said opening said trunnions being adapted to extend into slots in the spherical member whereby the reflector is connected therewith to be adjusted thereon; said slots being elongated to permit the reflector to be attached and removed from the spherical member; and a clamp on the conoidal reflector and adapted to engage the spherical member to hold the reflector to the spherical member and in adjusted position thereon.
In witness whereof we have hereunto set our hands in presence of two witnesses.
