UNITED p STATES HARRY J. MORSE, OF NORWICH, CONNECTICUT.

SHADE-HOLDER FOR INCAN DESCEN T ELECTRIC LAMPS.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed August 17, 1920. Serial No. 404,069.

T all w hom it may concern.

Be it known that I, HARRY J. Morse, a citizen of the United States, residing at Norwich, in the county of New London and State of Connecticut, have invented new and useful Improvements in Shade- Holders for Incandescent Electric Lamps, of which the following is a specification.

The object of my present invention is the provision of a shade holder, designed more particularly for use with incandescent electric lamps and constructed with a View to safely and strongly holding a shade but in such manner that by slight manipulation the shade may be quickly released for cleaning or for any other purpose.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof Figure 1 is a side elevation of my novel shade holder.

Fig. 2 is a diametrical section of the same.

Fig. 3 is an inverted plan view of the holder.

Fig. 4 is a horizontal section taken in the plane indicated by the line 44 of Fig. 2.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The body 1 of the holder is formed of sheet brass or other appropriate material in general bell form and is provided in its top with an aperture 2 for the passage of the wires complementary to an incandescent lamp. At the point 3 a groove is spun or otherwise formed in the body 1 for the swivel connection of the clamping annulus 4. The said annulus 4 is mounted on the lower portion of the body 1 so as to be turned through a part of a circle about said lower portion, the annulus 4 being preferably connected with the body 1 by the arrangement of a flange 5 on the annulus in the before mentioned groove 3. At its inner side the annulus 4 is provided with projections 6, disposed and movable in slots 7 in the lower portion of the body 1. It will also be observed that the body 1 is provided in its lower portion with spring clamping.

strips 8. The said clamping strips 8 are connected at 9 to the body 1, are opposed to the inner ends of the projections 6, and are provided in their outer sides with shallow indentations 10, these indentations l0 having for their function to seat the inner ends of the projection 6 after the annulus 4 has been turned through part of a revolution to press the strips 8 against the shade to secure the latter in the holder. From this it follows that there is no likelihood whatever of the annulus 4 casually turning about the body 1 and releasing the shade. When, however, a little stress is exerted on the annulus 4, the projections 6 will be moved out of the indentations 10 so as to permit of the spring strips 8 springing outwardly to release the shade.

Manifestly in practice the exterior of the annulus 4 may be and preferably is made ornamental as illustrated so as to enhance rather than detract from the finished appearance of the holder, and it Will be noted in this connection that When roughened for ornamental purpose the annulus will be much easier to turn than would an exteriorly smooth annulus.

Having described my invention, what I claim and desire to secure by Letters Patent, is

1. The combination in a shade holder of a body having slots in its lower portion, spring strips joined at one end to the body and arranged opposite said slots and having indentations in their outer sides at intermediate points in their length, and an annulus surrounding and swiveled on the body and having inwardly extending projections movable in the said slots of the body and opposed to the outer sides of the spring strips and adapted to seat in the intermediate indentations thereof.

2. The combination in a shade holder, of a body. having circumferential slots in its lower portion, spring strips joined at one end to the body and arranged within the body and longitudinally opposite said slots, and an annulus surrounding and swiveled on the body and having inwardly extending projections movable in the said slots of the body and opposed to the outer sides of the spring strips.

In testimony whereof I aflix 111 Si nature.

HARRY J. 0 SE.
