THOMAS THOMPSON JACOBS, OF MOUNT CARROLL, ILLINOIS.

IMPROVED MODE OF SECURING CHIMNEYS TO LAMPS.

Specification forming part of Letters Patent No. 35,239, dated May 13, 1862.

To all whom it may concern:

Be it known that I, Thomas Thompson Jacobs, of Mount Carroll, in the county of Carroll, in the State of Illinois, have invented a new and Improved Mode of Securing and Holding Glass Chimneys to Lamp-Tops; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in providing the upper part of a lamp-top with two clasps held and pressed on the chimney by a spring, which is operated by pressing the flat projecting portions of the clasps together where the spring is situated, which is attached to each of them for the purpose of allowing the chimney, to be· raised andlowered perpendicularly when fitted on or taken off, and holding the chimney firmly when it is on the lamp-top.

To enable others skilled in the art to make and use my invention, 1 will proceed to describe its construction and operation.

I construct my clasps of brass or any other suitable metal to fit closely around the outside of the lamp-top, as shown at A, Figs. 1 and 2,. and rivet them loosely to two ears projecting from the lamp-top, as shown at G G, Fig. 1, or in any other convenient manner, attach them to the lamp-top. I also provide my clasps with two projecting lips or catches, bent to_: the inside, as shown at c c, Figs. 1 and 2, for the purpose of extending over the edge or rim of the chimney to secure it firmly, and at each end of the clasps I have a flat projecting portion, as shown at II H, Figs. 1 and 2, to which the spring D, Figs. 1 and 2, is attached at each end, as at Β B, Figs. 1 and 2, and I also provide on the clasps on the outside of the flat projection ears large enough to receive the rivets and to hold the clasps to their places, as shown at F F, Figs. 1 and 2.

I operate my improvement by taking the chimney in one hand and with the thumb and forefinger of the other press the flat projecting portion of the clasps containing the spring together, and the chimney can be conveniently and expeditiously taken off or 'placed on the lamp-top without changing the perpendicular position of the chimney, thereby guarding against the flame of the lamp striking on the inside of the chimney to crack it or to blacken it with smoke. It can then be held in any position without danger of the chimney getting loose or falling off.
