DEI No. 515,048. Patented Feb. 20, 1894.
UNITED STATES PATENT OFFICE.
CHARLES H.-FORBES, OF PHILADELPHIA, PENNSYLVANIA.
SHADE.
SPECIFICATION forming part of Letters Patent No. 515,048, dated February 20, 1894.
Application filed April 5, 1893. fierial No. 469,229. (No model.)
To all whom it may concern:
Be it known that 1, CHARLES H. FORBES, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Shades for Lamps or Gas-Burners and Electric Lights, of which the following is a specification.
My improvement consists of a skirt made in sections or pieces that will encircle the bottom of a shallow shade. This skirt is composed of two rows of small tin plates those of the outer row arranged to overlie the meeting edges of the plates of the inner row.
The objects of my invention are to control the light and to reflect and cast or concentrate it where desired. This I do by inclosing it entirely around the sides, the best effect being secured by extending the bottom of the skirt about one inch below the bottom of the light and by raising one or more sections I can cast the light where needed.
The accompanying drawing shows a tin shade with a skirt in sections which are partly raised all around giving the contour of an ordinary shade but as each sect-ion works individually it is obvious that it will conform to a great many difierent shapes.
In the accompanying drawing A is a shallow tin shade for lamps or gas burners, with a wire band encircling bottom. The under sections 13 of the skirt are made square and are fastened to the wire band by clasping a portion of the section around the band and securing it by solder or rivets, thus forming a hinge sufficiently tight .so that the section will remain at any angle at which it may be placed. The upper sections or pieces 0 are made angular and hinged loosely to the wire band above and intermediate to lower sections B and lie loosely upon them, adjusting themselves to sections B at any angle and covering open space between sections B when the skirt is spread.
The ordinary pronged holder or support in general use for lamps and gas shades and the holders used for electric light shades will be applied to this shade.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
The combination with a lamp shade, of a sectional shade skirt composed of a double row of pivoted plates or pieces; those of the inner row being movable independently of the other pieces of that row and adjusted to any desired position and those of the outer row being intermediate to those of the inner row and adjustable therewith as described.
