ADJUSTABLE LAM P-SHAD E.

SPECIFICATION forming part of Letters Patent No. 470,603, dated March 8, 1892.

Application filed June 19,1891. Serial No. 396.302. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, HENRY SCHLOERB, a citizen of the United States, and a resident of Greenville, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Adjustable Lamp- Shades, of which the following is a specification.

My invention relates to improvements in lamp-shades so arranged that the shade may be placed at will at different angles, so as to give varying areas of shade and light and to concentrate or deflect the light in different directions, as maybe desired. It is designed for use not only in connection with lamps, but also for gas and electric lights.

Figure 1 represents a side elevation of a hand-lamp, to which is attached the shade with its supporting-arm, hinges or pivots, and spring-clasp. Fig. 2 is a plan view of the same, omitting the lamp. Fig. 3 is a detail side view of Fig. 2. Figs. 4 and 5 represent, respectively, in side View and top View the shade provided with an extension-arm and a counterbalancingweight in accordance with my invention.

Similarlettersreferto similar parts throughout the drawings.

A represents alamp; B, an elliptical springclasp made of two pieces of thin metal clamping together over or around a central body and arranged together so as to be separated at one end of each piece, which ends are curved or formed each into a small circle, and the two pieces are joined at or near the other ends to an intermediate center pin 1), passing through the inner end of the bar 0, and the adjustment made for the position is obtained by a pin 0, passing through the fiat ends of the clasp B and through a segmental slot 6, which is near and part of one end of the supporting-bar G.

0 represents the supporting bar or arm of the shade and is adjustable to any position that may be desired by the eccentric leverclamp d, working against one of the fiat ends of the clasp B, adjacent to the slot or link 6, the pin 1) in the end of the bar 0 being the center from which the segmental curve of the slot 0 is obtained. The edges of the said slot e have a milled serrated corrugated or roughened surface, upon which the closed ends of the clasp B are impinged by the clamp 61 at the pin a, which plays in slot e in the eccentric clamp d, thereby securing or locking-the arm 0 firmly' in any desired position in which it may be adjusted within the limits of the slot 2. The bar 0 is grasped between two projecting lugs E E by a similar pin 0 and by a lever-clamp e, which is pivoted on the projecting end of the pin 0. Attached to lugs E E is a strip of metal. f, firmly affixed to said lugs E E and to shade D by fasteners 9, bearing against the outer face of the shade and having their ends passing through the shade and through the inner stripf and clinched against the latter. The shade D, being thus connected with the arm 0 by a revolving center at pin a, may be adjusted in any desired position within the radius of a perpendicular circle by means of the eccentric clamp e, which, acting on the said. pin and against the lug E, locks and firmly holds the shade in the desired position. One of the lugs E may be omitted, if desired, and the pin 0 may be constructed with a shoulder, and such combinations will answer the same purpose. Eccentric cams or screws may also be substituted, if desired, in the place of eccentric lever-clamps d and ewhere the same are shown, as in Figs. 4 and 5.

The sliding bar 0, Fig. 4, may be added for the purpose of extending or contracting the length of the arm supporting the shade, if desired, as shown in Figs. 4 and 5.

The shade D may be composed of bristol or card board or other suitable opaque material, and may, if desired, have a reflecting inner surface, so as to more strongly reflect the light, and may be of. any desired shape and either plane or curved.

Fig. 4 is a View of the bar 0, to which is attached an extended bar 0', sliding in ways N N on the bar 0, h h representing screws which maybe used in place of eccentric clamps for the purpose of clamping the bar 0 and the shade D in the position desired. In this figure K represents the Y-shaped arms of a bar L, hooked into the circled ends of the clasp B to support a counter-weight M, which counter-weight may be of lead or other metal.

A plan view of Fig. 4 is shown in Fig. 5.

Fig. 5 represents means for counterbalancing the shade when adjusted to a hanging or swinging lamp or light, in which is shown the extension-bars CC, and the other parts, as in Fig. 4, the counterweight-bars K L, and the counter-weight M, attached as aforesaid and adjustable, so as to balance the shade D.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with light-producing devices, of a shade, a strip f, secured to the inner side thereof and having two parallel lugs E, a bar C, having one end pivotally clamped between said lugs and the opposite end carrying a pin 1) and a segmental slot between the two ends, with a spring-clasp consisting of two metal plates, each having a curved end and a flat end, and the pivot-pin 19 between said ends, the Hat ends being united together and to the bar 0, through the segmental slot of the latter substantially as described.

2. The combination of a shade, a strip f, secured to the inner side thereof, and a fastener bearing against the outer face of the shade and having its ends passing therethrough and through the strip f, with lugs E,

projecting from the inner face of the strip f,

and a bar 0, having one end pivotally clamped between said lugs and the opposite end piv.

support, and lamp-clasp with a bar having Y-shaped ends hooked into the curved ends of the metal clasp, and a weight adjustably retained upon said bar to counterbalance the shade, substantially as described.

4. The combination, with a lamp-shade D, of the supporting-bar O and C, constructed as described and shown, and the elliptical spring or clasp B, connected by pins, being revolving centers, governed and fixed as to position by clamping devices and counterweighted by the bar K L and weight M, substantially as set forth, all for the purposes specified.

Signed at New York city, in the county of New York and State of New York, this 18th day of June, A. D. 1891.
