Letters Patent No. 97,772 dated December 14, 1869-.

IMPROVEMENT m SHADE-RINGS Iron LAMP-BURNERS.

The Schedule referred to in these Letters Patent and making part of the same. I

To all whom it mag concern i allow of its removal when the criinped springs are Be it known that I, H RAM W. HAYDEN, of Watera bury, in the county of New Haven, and State of Connecticut, have invented and niade a new and useful Improvement in Shade-Rings for Lamps, and the followingis declared to be a correct description of the same.

Shade-rings have before been made removable from the lamp-burner, so as to be taken off or replaced as the burner was required for use, either with or without a globe or shade. These shade-rings'are liable to slip off the edge of the base of the burner, particularly in cases where a heavy shade is used, or the Iampjs moved from-place to place.

My invention is to secure the shade-rim g more firmly inplace, and present the same becoming loose, and slipping off the edge of the base of the burner when subjected to the motion, the grease, or the expansion by heat, to which such shade-rings are exposed.

Said-invention consists in a series of crimped springs,

7 applied around the inner periphery of theshade-ring,

in combination with the raised rib or head around the edge of the base of the burner, so that said crimps of the springs, setting over the said head, eifectually grasp said head and hold the shade-ring to place, but

sprung back over such bead.

. 'In the drawing- Figure 1 is a vertical section of a lamp-burner, with the said shade-ring applied; Figure 2 is a section, and

Figure 3, a. plan of the shade-ring, detached.

The lamp-burneris formed in any usual manner.

I, haves'hown the wick-tube a, deflector or draughtplate I), and base. 0, for the burner.

Around the edge of the base 0, is the head or rib 5.,

d is the shade-ring, formed with the supportingspurs c and springs o. i

These spiings'o are crim'ped at 22, to set over the head or rib i, as aibresaid, and hold the shade-ring properly inpl-aoe, or allow of its removal when the springs are pressed back to slide over the rib t.

I claim, as my invention The crimps 2 2 in the springs o of the shade-ringd, in combination with thebead 5 around the base of the burner, as "and for the purposes specified.

'Dated'November 13, A. D. 1869.
