REDWOOD CITY, CALIFORNIA.

- LAM P-SHADE SUPPORT.

' SPECIFICATION forming part'of Letters Patent No. 363,916, dated May 31, 1887.

Application filed December 28, 1886. Serial No. 222,775. (No modeh) To all whom it mayconcern:

Be it known that we, REUBEN HENRY S11v1;

and ISAAC POLLOOK, citizens of the United and Redwood City, in the counties of Nevada .10 Our invention relates to improvements in.

lamp-shades; and it-consists in certain novel features, hereinafter descnbed and claimed.

Our invention is fully illustrated in the acoompanying drawings, in whichr Figure 1 is a perspective view of a portion of a lamp with our improved shade attached thereto. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical section in detail of the spring-adjusting device on line m x of Fig. 2.

Fig. 4. is a detail perspective view of the spring-adjusting device.

Referring tothe drawings, in which similar letters denote corresponding parts in all the figures, A is a chimney, and B the collar, ofalamp.

O is a band of sheet metal adapted to-encircle the collar 13, the ends of which band are free and bent outwardlyto form flangesD D.

The arm Dis provided with a threaded opening, (1, and the arm D has a plain opening, (1, larger than d.. E is a thumb-screw, which passesloosely through the opening (I and screws into the opening (2, thereby making the band adjust 3 5 able to any lamp-fount. I F is a supporting-rod, comprising the long vertical arm. G, which is flattened, as shown, for a purpose hereinafter explained, the horizontal arm H, and the short arm I, at right an- 0 gles to the arm H. Said arm I is also flattened,

or made rectangular in cross-section, to enterthe oblong loop or sleeve K on the band C. -This rectangular construction is designed to prevent the arm I from turning in the sleeve or loop K, but allows endwise movement.

K is aloop or sleeve similar to K, attached to the band C at a point diametrically opposite to loop K.

L designates a semi-cylindrical shade of any suitable light material, and provided upon its front side with the metallic adjusting-bracket States, residing, respectively, at Grass Valley and San Mateo and State 'of California, have M; Said adjusting-bracket M is formed'of one piece of sheet metal, having the boX' N rectangularin cross-section,and ears or flanges 0, provided with openings to allow of the in- 5 5 sertion of pins or rivets p to secure said adjusting-bracket M firmly to the shade L. The angles r r of the box N are split, as shown, for a considerable distanccin from the upper-and lower'ends ot' the box N, and the=tongues of Q metal between said split angles are. turned in toward the shade to form the springtongues S S"one at the top. and the other at the bottom of the box N. The projecting cornersT'T at the upperand lower ends of the box N remaining after the tongues S S are turned in 1 are then pressed laterally toward each other,

to prevent the spring-tongues S from coming back to their original positions, therebylimiting their movement. The long flat vertical. 7o arm G of the shade-holder is then inserted under the spring-tongues S S-namely, between said springs and the shade L- -and the pressure of the said springsS S being toward. the shade L, the shade will be held at any desired height along the vertical rod G by the pressure of said spring-tongues S S againstand upon the said rod G.

The springs automatically hold the shade in its adjusted positions, for as'soon as the operator ceases to move the shade the tonguesprings bite against the bar G and hold the shade in the position set. It will thus be seen that we have an easily-applied shade-which is adjustable to any height desired; When the 8 5 shade is not needed, it is only necessary to withdraw the shortarm I from the loop K and allow the collar 0 to remain around the -collar B of lamp-chimney.

.structed that we can detach the parts thereof to facilitate the packing or transportation thereof, which is an advantage over, shades now in general use. Having thus described our invention, what 2 V as ,916

lamp, the shade, and a bracket secured to the shade and provided at its endswith integral spring-tongues projecting in opposite directions to bind against the supporting-rod, substantially as set forth.

3. The combination, with the band C, and

the supporting-rod F, attached thereto, and 20 having the vertical arm G, of the shade L, having the bracket M on its front side to receive the arm G, said bracket being provided with integral spring-tongues to hold the same on said arm G, and limiting-ears to hold the 25 springs to said arms, substantiallyas specified. In testimony that we claimihe foregoing as our own we have hereto afiixed our signatures in presence of two witnesses.
