This invention relates to a Christmas tree decoration, and particularly to a novel combination of reiector and lamp. It is now the common practice to decorate Christmas trees and similar objects with small electric lamps, which lamps are often of various colors. It is also now common practice to use refiectors of various ornamental shapes `with such lamps. While such reflectors and lamps have been used, the lamps of the prior art have been of uniform color or have had all parts thereof of uniform degree of light permefability. Y'

It is an object of the invention to provide a lamp having thereon portions of diierent degrecs of light permeability and of various ormations.

It is another object of the invention to provide a Christmas tree electric lamp having a bulb and plug, said bulb being colored and translucent for the greater pant of its area,

but having a portion adjacent the plug which is clear.

These and other objects andadvantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which,

Fig. 1 is a view in front elevation of a reector and lamp;

Fig. 2 is a horizontal section taken on the line 2 2 of Fig. 1, as indicated by the arrows;

Fig. 3 is a view in front elevation of a modified form of refiector and lamp;

Fig. 4 is a horizontal section taken on the line 4 4 of Fig. 3, as indicated by the arrows; 1

Fig. 5 is a view in front elevation of a relector and lamp of further modified form;

Fig. 6 is a horizontal section taken on the line 6 6 of Fig. 5, as indicated by the arrows. Y

Referrin to the drawings, in Fig. 1 is shown a re ector 10 made of sheet material, preferably metal, the same having a shape, 1n front elevation, of a five-pointed star. o The reflector 10 is curved toward the front,

as seen lin the drawings, the curvature being uniform with the central axis extending normal to the reiiector at the center thereof. The reflector l0 has its surface formed with a multiplicity of small substantially semispherical depressions 10a. The surface of the reflector, including the depressions 10a, is quite highly polished so as to give a high degree of reflection. While these depressions may be disposed in various ways and arrangements, in the embodiment of the invention illustrated, they are shown as being arranged in rows parallel to the sides of the star form-v ing the reflector. The reiiector 10 has a central aperture therein and a bushing or washer 11 of insulating material is provided havin a central aperture considerably smaller than the aperture in the reector, said Washer 11 being placed against the rear side of the relector with its central axis co-axial with the central axis of the reflector. Said washer is secured to the reflector by a plurality of circumferentially spaced and preferably pointed tangs 10c extending through washer 11 and bent over on the outer side thereof in a manner similar to that shown in Fig. 4. A lamp 12 is provided having the bulb portion 12a of glass, or similar transparent material, vand the rear part comprising the threaded sleeve 12b and the tip Contact 12a insulated from said sleeve. The lamp 12, preferably, is provided with some coating or color, as indicated by the shading. Any particular color may be used. The lam 12 is provided with a portion 12d,-and while this portion may be of various shapes and variously arranged, in the embodiment of the invention illustrated, it is shown as a zigzag band extending circumferentially about the bulb 12a substantially at the widest portion thereof. The band 12d thus has a plurality of pointed portions 12e, and these are ar ranged with their central axes in alinement with or directly in front of the central lines of the respective points of the reliector 10. It may be stated that the ortion or band 12d is of different color or e ee of li ht permeability than the remain er of the ulb 12a and while various degrees of light permeabilitmay be used, as many different colors, in t e embodiment -of the invention illustrated, the band 12d is shown as belng clear.

In operation, the reflector and lamp disclosed will be mounted on a Christmas tree, or other Christmas decoration, in the usual manner, by screwing the sleeve V12b of the lamp into the customary lamp socket, the reflector 10 being clamped or held between the lamp and lamp socket. When the lamp 12 is illuminated, the color in the main portion of the bulb will be reflected from the surface of the reflector 10 so that said reflector will show the color from the bulb in the shaded -portion 10b. The band 12d, however, will cause the surface of reflector l() to show a different reflection about the border of the same, as indicated by the unshaded portion in Fig. 1, thus forming two zones of different reflecting effect on the reflector. If the band 12d is clear, this portion of the reflector will show with a very high light. If the band 12d is of a different color, this color will be reflected about the edge of the reflector 10. A very striking and beautiful effect is thus obtained on the surface of the reflector 10. The pointed portions 12e as stated are circumferentiall alined with the points or zones of the re ector so that the border of said reflector is bright, as shown by the unshaded portion in Fig. 1.

In Figs. 3 and 4, a different form of reflector 15 is shown having a plurality of radially extending points 15e. The surface of reflector 15 is also highly polished and provided with a multiplicity of substantially semi-spherical depressions 15a, such as shown in the drawing. Reflector 15 is also curved forwardly uniformly about a central axis` and is provided with a central aperture 15b. A washer or bushing 16 of insulating material engages the rear of reflector 15 and is held thereon by aplurality of circumferentially spaced tangs 15e passing therethrough in the same manner as already described for washer 11 in reflector 10. A lamp 17 is provided having the bulb portion 17 a which is Coated, or otherwise colored having the threaded sleeve 17d insulated from the tip contact 170. The bulb 17a is provided with a portion 17?) of a dierent degree of light permeability from the remainder of the bulb and while this portion may be of various shapes and arrangement, in the embodiment of the invention illustrated, it is shown as a circular band. The portion 17?) may be either of a different color or may be clear.

When the reflector 15 and lamp 17 are assembled on a Christmas tree or other similar device, as already described for lamp 12 and reflector 10, the color on the main portion of bulb 17 will be reflected from the central part of the reflector, as indicated by the shading 15d in Fig. 3. The band 17 o, however, will emit light of a different coloring or intensity which will cause a different reflection from the outer ends of the points 15a, as indicated by the unshaded ortions in Fig. 3, thus giving zones f di erent reflecting effect. If the band 17?) be clear, this latter portion will show quite bright and if the band 17?) be of a different color, this color will be reflected from the portion outward of the portion 15d. A beautiful and striking effect is thus produced.

In Fig. 5, another form of reflector 20 is shown having its periphery formed with a plurality of semi-circular lobes 20a. The surface of the reflector 20 is also highly polished and provided with a multiplicity of small semi-spherical depressions 206 similar to the depressions 10a. While the depressions QO may be variously arranged, in the embodiment of the invention illustrated, they are shown as disposed in a double row about the outer edge of the reflector 20 and also extending inwardly in radial lines in double rows. Reflector 20 is also provided with a washer 21 extending across the central aperture in reflector 20 secured thereto in a man ner already described for washers 11 and 16. A lamp 22 is provided having the usual bulb portion 22a, the rear sleeve portion 22?) insulated from the tip contact 220. rlhe bulb 22a will be coated or otherwise colored and the same is shown as having circumferentially spaced portions 2205 of a different degree of light permeability than the remainder of the bulb. While the portions 22?) may be variously arranged, in the embodiment of the invention illustrated, they are shown as extending radially and outwardly toward the pointed end of the lamp bulb. Portions 22a? may be either clear, or of a dierent color from the remainder of the bulb.

In operation, when the reflector 2O and lamp 22 are assembled and held, as above described, and the lamp illuminated, the color on the main portion of the bulb will be reflected from the reflector 20, as indicated by the shaded portions in Fig. 5. The portions 22d, however, will cause portions or zones of a different reflective effect on reflector 20. The portions 22d will be disposed with their central lines in alinement with the radial line extending between the lobes 20a, at each `side of which latter lines the rows of depressions 20?) are disposed. The radial rows of depressions 20o will, therefore, be illuminated by the lightissuing from the portions 22d, and if the portions 22d be clear, these radial rows will be highly illuminated and a very bright reflecting effect secured. It' the portions 22d be of a different color from the remainder of the bulb, this color will be reflected along the radial rows, as indicated by the unshaded portions of Fig. 5. A very handsome and striking effect is thus produced.

The reflector illustrated is substantially the same as that disclosed and claimed in applicants U. S. Patent No. 1,617,221 issued Feb. 8th, 1927.

From the above description it is seen that applicant has provided a novel and ellcient electric lam for Christmas trees and one which will glve new, important and pleasing results. The ortions of the lamp which emit different kin s or colors of light lwill produce diierent effects on the various reflectors 10 which may be used therewith which effects will be very pleasing, beautiful and highly ornamental. It is also pointed out that when the lights are used without reflectors as is common on Christmas trees, the lightwill shine through the clear portion and will illuminate other objects on the tree. With the structure shown in Fig. 6 the objects in the rear of the lamp and in the rear part of the tree will be illuminated, as trees are often placed in corners of a room, the rear of the tree tends to be dark. With such lamps as disclosed this part of the tree will be illuminated and beams of light will shine thereinto giving a very pleasing and ornamental effect. It

is also pointed out that by having a clear portion on the bulb more radiation of heat isv obtained. As is well lmown, Christmas tree lamps get quite hot due to the translucent coating used to get the color thereon.

It w1ll, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parte without de arting from the sco e of the invention, w ich, generally state consists in the novel parts and combinations of parts v disclosed and deiined in the appended claims.

This application is a division of applicants coi-ipending' application for Christmas tree re ector and lamp, Serial No. 83,606, led

40 January 25, 1926, vallowed March 5, 1927, which application has since the filing of this a plicatlon matured into U. S. Letters Patent o. 1,632,850 issued on June 21, 1927. What is claimed is:

1. A Christmas tree lam bulb having the greater portion of its sur ace of one color and translucent and having a zone of clear glam extending about said bulb in a. zigzag so 2. A miniature electric lamp comprising a bulb and a plug to which said bulb is attached, said bulb aving a body portion extending -rom said plug to its outer end, said bod have ing the greater and outwardly dispo portion of its area colored and translucent, said bod having a smaller clear portion adjacent sai plu extending circumferentially of said body, w ereby li t can shine throu h said v clear portion an produce a high re ecting eilect on a reflector.

In testimony whereof I aix m si ature.
