COMBINED SHADE AND REFLECTOR.

Application filed August 9,1927.

The object of the present invention is the manufacture of a combined shade, reflector, and holder, in which a reflector cover fits closely about one portion of the bulb, and

shade or screen. This shade normally screens the uncovered part of the bulb and is adapted to receive a combined beam consisting of light reflected from the reflector as well as direct light from the lamp.

The present invention contemplates a reflector shade and holder directly mounted on the lamp bulb and capable of permitting a movement of the shade in all directions so that it may be placed in any desired position about the lamp bulb and the light directed as desired.

' The invention is particularly directed toward the type of reflector and shade designed to be directly supported from incandescent lamps. A shade or screen of glass or other translucent material is directly supported on an opaque reflector adjacent to an incandescent lamp so as to obtain a beam of light in the desired direction or a desired color. Under many conditions it is also desirable to obtain an asymmetric light beam whose axis may be adjusted to a variety of angles and which may be turned about this axis to obtain the desired lighting effects.

One of the objects of the invention is to provide a reflecting cup about the bulb of the incandescent lamp so as to control the light distribution.

The parts are so arranged that the shade whether of disc, lens, or refractor form, may be moved about the lamp bulb in a variety of positions so as to direct the axis of the beam in the desired direction irrespective of the angle of the lamp socket. Where an asymmetric distributing lens is used, the lens may be turned so that the maximum light distribution is brought into the desired plane.

A further object of thepresent invention is to provide a shade holder more especially of the class above referred to wherein the incandescent lamp may be passed through the shade holder parts and swung to position to secure the shade holder on the lamp bulb without the use of tools or the connecting and disconnecting any of the parts.

The accompanying drawings show, for purposes of illustration, one of the many possible embodiments in which the present Serial No. 211,666.

invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In these drawings:

Figure 1 is a side view of an incandescent lamp, a reflector, a shade and support, showmg the adjustment of reflector, shade and movable supporting member in the plane of the longitudinal axis of the lamp;

Figure 2 is a sectional view on the broken line 22 of Figure 1;

Figure 3 is a side view of the parts showing the position assumed when the lamp is being inserted into the shade supporting member or being removed from it; and Figures 4 and 4 are fragmentary views of an asymmetric cup suitable for use in the present invention.

The essential parts of the invention are a reflecting cap, a shade and various supporting parts herein described. The reflecting cap 22 may conveniently be in the form of an aluminum stamping and is found to redistribute the light and direct it out through the lower side of the lamp and toward the shade 10 when the parts are in the position indicated in full lines in Figure l. A band 26 which may conveniently be in the form of a wire member is attached to the rear ends or tips 27 of the cap 22. This band is adapted to pass about the neck of the bulb as indicated at 25.

The shade as indicated at 10 of the drawings may be of any desired form. It is as here shown in the form of a glass lens having a central aperture 11. An apertured disk 12 or other form of packing, is placed in the aperture in the lens, as indicated. Two small metal washers 13 and 14 are placed against the sides of the glass disk and a clamping bolt 15 passes through the packing 12 and washers 13. and 14.-. A nut 16 is threaded onto the bolt for clamping these parts together. A yoke 17 has a threaded hole 17 to receive the bolt 15, and a coiled spring 18 is carried between the head of the bolt 15 and the washer 13 so that the yoke, screw, washers and lens may be also secured in place by tightening up the nut 16.

The yoke 17 may be made out of a bent piece of sheet metal and is provided at its upper ends 19 and 20 with pivot pins 21 to support a cover member or cap 22 of spherical shape and adapted to engage, as indibulb portion 23 cated in the drawin s, about one-half of the of t e incandescent lamp 24, andjto extend a short distance beyond the equator of the bulb toward the neck 25 of the bulb.

In placing the shade holder in the lamp bulb, the parts are brought to the position indicated in full lines in Figure 3. The base of the lamp is passed upwardly between the band 26 and the cap 22, which is cut away in its edges as indicated at 28 to accommodate the neck of the lamp. The lamp is then moved in a clockwise direction to bring the bulb in against the reflecting cap whereupon the cap 22 and band 26 will swing or pivot on pins 19 and 20 toward the dot and dash line position indicated in Figure 1 so as to bring the spring 18 against the surface of the lamp bulb. This spring presses against a large area of the lamp bulb and securel holds the shade holder on the lamp in a1 positions into which it may be brought. The band 26 prevents the s ring from forcing the lamp out of the hol er when the spring is near the tip of the bulb. When one desires to remove the shade holder from the lamp, it is merely necessary to bring the shade to the dot and dash lines of Figure 1, whereupon the spring 18 will engage the edge 29 of the cap 22 so that the bulb is released and the lamp may be swung down to the dotted line position shown in Figure 3.

From the foregoing, it will be apparent that the present form of shade holder is well suited for carrying shades directly from in candescent lamps and one wherein the shade may be very securely fastened on the lamp in any desired position. The reflecting cover 22 reflects a considerable portion of the light back toward the lamp center and this reflected light is added to the direct light from the lamp and therefore increases the light which falls on the shade. This increased light is available throughout a wide range of adjustment of the shade. The shade acts as a screen for the direct and reflected light, and when in the form of a re fractor may redirect substantially all the light from the lamp into desired directions.

It will be noted that the shade holder may be swung in the plane of the axis of the lamp bulb through about 90, as indicated in Figure 1, also that the axis, shade holder and shade may be bodily rotated about the axis of the lamp bulb to bring it to any desired position. Where one desires an asymmetric distribution of light in the emitted beam, an asymmetric refracting cup, such as shown, may be used. Such a refractor may have a series of circular prisms 30 on one side and parallel refracting prisms 31 on the other side for concentrating the beam collected by the prisms 30. Turning the refractor from the position of Figure 4 to that a Figure 4 will vary the light distribution in the desired manner. This refractor is more particularly described in application Serial Number 7 01,97 0, filed March 26, 1924. It may be twisted about on the supporting pin or bolt 15 to give the desired distribution of light and may be readily removed from this pin whenever desired.

The device is especially applicable to installations where it is not practical to install elaborate or large reflector shade types,

and is especially useful in cove or window lighting, or as a directional unit, part of the bulb equipment, in larger installations cmbodying other directing means.
