UNITED STATES BOSE E. WILSON, or LONG BEACH, cnmroama LAMP SHADE.

Application filed April 7, 1923. Serial No. 630,593.

To all whom it may concern:

Be it known that I, Rosa E. WILSON, a citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, have invented new and useful Improvements in Lam Shades, of which the following is a speci cation.

My present invention, is an improved form of lamp shade, or a combination comprising 1 a shade of novel type; and it is a special object of this invention to provide means wlfereby the distribution of light \from a shaded lamp may be varied at will.

It is one object of this invention to provide a lamp shade comprising one or more sectors or triangular or similar elements which can be independently elevated, in order to throw a comparatively strong light in a desired direction. For example, it is an object of this invention to provide a shade suitable for use either upon a table lamp, about which readers may be so disposed as to require a variable illumination, or a piano lamp, which may be required to throw a strong light in one direction only, with means to facilitate a suitable control of the illumination in various directions.

It is a further object of my invention to provide a lamp shade of the character referred to, which shall compriseparts so related that they may optionally beso disposed as to present the usual appearance of, a table lamp, or a piano lamp, or the l1ke,

but which shall nevertheless be capable of easy adjustment in such manner as to project a comparatively strong beam of light in one or more selected directions, as required.

It is a further object of my invention to provide a lamp shade of the general character referred to which shall be capable of manufacture and sale at a moderate cost, and which shall also beof attractive a arance and easily adjustable, and not lia e to derangement or undue wear of relatively mov- 'ing parts. I

Other objects of my invention will appear from the following description of a preferred embodiment thereof, and the appended claim, taken in connection with the accompanying drawings, in which Fig. 1 is an elevation, with parts broken away. a x i Fig. 2 is a top plan view, corresponding to Fig. 1, with parts broken away in a different manner.

Fig. 3 is a perspective view of a lamp of similar design.

Referring in detail to the above form of my invention which I have chosen for illustration, 1 is a stand, surrounded by a center post 2, provided with lateral arms 3, at the ends of which are shown incandescent bulbs 4: and above the parts refered' to I may provide any suitable means for supporting a lamp shade of my preferred design. In the embodiment shown, a vertical rod 5 provided with a shoulder 6, is shown as seated rotatatively within the post 2, and as provided with arms 7, carrying a lower ring 8, and also with arms 9, carrying an upper ring 10, the upper end of the rod 5 being optionally provided with a ball or knob 11, and a set screw 12 being optionally provided to secure the rod 5 in any desired vertical or angular position.

It being understood that any desired number of the sectors which I may support from the rings 8 and 10 may be made relatively movable, I have chosen for illustration a form in which four of the sectors referred to are adapted to be relatively moved, these being the alternate sectors respectively lettered A, B, C and D in Fig. 2; and to facilitate the retention of the respective movable sectors in any desired position, I may provide each of the said sectors with a frame 12 of heavy wire or equivalent material, and I may also extend the wire which constitutes the frame of each sector, preferably coiling the same about the upper ring 10, in the manner shown at 13, and providing the same with an extension 14, adapted to contact with the ring 8. As shown, the extension l l is provided with an outer end stop 15, which may prevent a sector from dropping below a predetermined position, and with a hook or inner end sto 16, which may prevent the sector from rising above a predetermined position, and optionally also with an intermediate notch 17, which may hold a sector in a partially elevated position.

Each of the sectors may be covered with fabric or other suitable material, and one or more of the lights 14 may optionally be 10 provided with reflecting means, such as the concave mirror 18, which may be universally pivotedrel-atively to a movable collar 19, and may thus be available when it is desired to project a strong beam 01 light no to a considerable distance. Additional reflecting surfaces may optionally be employed at R and R.

It will be understood that by a suitable use of the adjusting means described above, a shade of my novel construction may be set at a desired elevation relatively to any suitable sources of light, and the shade may be so rotated relatively to its supporting base and the lamps secured thereon, as to throw a beam of light of a suitable strength, in any desired direction. It will furthermore be obvious that a shade provided with my improvements may present any usual or desired artistic effect, the construction by which I enlarge the usefulness of alamp shade being comparatively simple, and the mechanism by which my novel results may be obtained being practically concealed.

Although I have described in detail one preferred embodiment of my invention, it will be understood that various parts thereof might be independently used, and that various modifications might be made without departing from the spirit and scope of my invention as the same is indicated above and in the following claim.

What I claim is:

A device of the character described comprising a standard, a center post set in the standard and in alignment therewith, arms extending laterally from said post and adapted to carry incandescent lamps, a rod in alignment with said post and rotatably seatedtherein, two sets of radially disposed arms carried by said rod, a ring carried by each set of the radially disposed arms, the rings being in horizontal planes one above the other, a lamp shade, said shade comprising sectors, frames for said sectors, said frames being pivoted to the upper ring, extensions on the frames of the alternate sectors of said shade, a hook on the end of each of said extensions adapted to engage the lower ring to hold said alternate sectors in raised positions, and a universally pivoted concave reflector adapted to intensify the illumination from a lamp.

In testimony whereof I have signed my name to this specification.

ROSE E. WILSON.
