ARTHUR J. TIZLEY, OF YORK, N. Y., ASSIGNOB TO EDWARD F. CALDWELL COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

. SHADE-HOLDER.

Specification of Letters Patent.

Application filed Harchfl, 1918. Serial No. 221,483.

To all whom it may concern:

Be it known that I, ARTHUR J. TIZLEY, a citizen of the United States of America, residing in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Shade-Holders, of which the following is a specification;

My inventionrelates to shade-holders and partlcularly 'to a support for shades of the inverted globe type, the object of my invention being to improve the construction shown in the Evans et al. Patent 1,192,049, by rendering the locking device thereof automatic.

In the accompanying drawing,

Figure 1 is a section through a fixture showing my invention applied to the globe holder in one form;

Fig. 2 is a plan of the globe holder detached;

Fig. 3 is a broken plan of one of the supportin arms, showing the supporting finger thereo in position to permit the adjustment of the globe;

Fig. 4 is a side elevation thereof, showing the locking sleeve in section. ,4

In the shade holder shown in the Evans patent above mentioned, one of the support: ing arms is made in two parts plvoted together and normally held in alinement by a locking sleeve. The latter, however, is loose upon the arm and must be moved positively in both directions first to releasethe sections to permit them to pivot with relation to each other, and thereafter again to lock the same in alinement. Moreover, when the parts are released, the globe-engaging end or finger of the arm is free to swing and does not maintain any precise relationship to the fixture end of the arm, with the resultthat it is apt to get in the way during the adjustment of the globe on the support. By my present improvement, I provide the locking sleeve. with means for automatically returning it'to locking position when the globe-engaging finger is swung up into operative position, and, at the same time, mamtam the finger in predetermined out-of-the-way position during the adjustment of the globe on the holder.

While the globe holder may ap lied to fixtures of various sorts and may e supported in any suitable way, I have here in- (icated it a plied to a lamp socket 10, on the casing of w ch is' secured an ordinary globe rods fixedly secured at their upper endsto a channel ring 18 adapted to be inserted wi Patented July 30, 1918.

in the skirt of the shade holder 11 and engaged by the set screws 12 to hold it in position. The two arms 15 and 16 are rigid throughout their length. The arm 17 is'di-' 'vided, and the outer free end thereof forms a globe-engaging finger 19, pivoted thereto at 20. A lap joint between the sections of the arm is formed by cutting away the pivoted ends of the arm sections, and the end of the finger 19 is beveled at 21 to permit the finger to swing downward as indicated in Fig.

- 4, but forming a stop bearing against a simlar incline 22 on the fixed end 17 to prevent the upward swlng of the finger. 19 and halting the latter when in alinement with the fixed end 17.

In order to hold the finger 19 in alinement wlth the fixed end of the arm 17, I pro-' vide a locking sleeve 23, sliding on the fixed portion 17 of the arm and abutting at one end against the eads of the pivot pin 20 which prevents t e sleeve from running down the finger 19. The locking sleeve 23 is of greater diameter than the arm 17 and forms a housing for a coil spring '24:, one end of which is offset and passed into a hole 25 in the arm 17 while the other end there-' of abuts against a shoulder 26 formed in any suitable way at the end of the sleeve adjacent the joint between the arm sections. The end of the sleeve is preferably rounded or beveled at 27 to facilitate the automatic action of the locking sleeve when the finger 19 is swung up into globe-engaging position.

The operation of the device is readily understood. Under normal conditions, the locking sleeve holds the finger 19 in alinement with the arm 17 as indicated in Figs. 7

only action engagement swing up the finger 19 into alinement With or the globe by the holder is to the arm 1?. 9n its upward movement, the beveled end 21 of the finger l9 bears against the bevel 27 on the -locking sleeve 23 and forces the latter up the arm 17 against the action of its spring 2d. As soon as the finger 19 comes in alinement with the arm 17, the sleeve 23 is automatically returned by its spring 2% into locking engagement there with and rests against the heads of the pivot pin 20. The finger 19 is thus held rigidly in supporting position.

The improvement thus provided does not alter in any Way the appearance-of the support, and has the advantages above pointed out, in addition to those disclosed in the Evans patent. The manner in which the arm is secured to its supporting ring is immaterial, as is also the contour of the arm and the shape of the supporting finger, and I do not limit my claim of invention to the precise form of construction illustrated.

claim:

1. In a shade holder an arm, a shade-engaging finger pivoted thereto but movable to out-of-the-Way position during the adjustment of the shade on the holder, and a spring pressed locking member holding said finger in both positions, together with means automatically displacing said locking device as the finger is moved to shade-engaging position but thereafter releasing said locking device to permit it to return under the acreveal 'out-of-the-way position during tion of its spring to locking positi and thus hold the finger in shade-engaging position.

2. in a shade holder a supporting arm having jointed thereto shade-engaging finger, in combination with a displaceable spring pressed locking mber said arm and finger to d latter in normal shade-engaging releasing said locking me m reaches its normal positio tether o the automatic return of said member looking position under the action of spring.

3. In a shade holder an arm, a shade-engaging finger pivoted thereto bu ovable to la r.

ment of the shade holder, a locking sew. mounted on said arm and engaging said finger to hold it normally in looking" position, together with a cam lug on said finger engaging said sleeve to displace the same out of obstructing position as the finger is brought into its normal position.

i. In a shade holder an arm having a shade-engaging finger pivoted thereto, in combination with a spring pressed locking sleeve mounted on said arm and engaging said finger to hold the latter in normal position with relation to the arm, together with a cam lug on said finger automatically displacing said sleeve out of obstructing position as the finger is moved into its normal shade-engaging position.

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