Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
“For a mode of Affixing and Applying Glass Chimneys, similar to those used with the various kinds of Argand Lamps, to the cork tops used with glass lamps; Deming Jarves, Boston, Massachusetts, July 20.
The tops of the glass lamps in ordinary domestic use, consist of cork enclosed between two pieces of metal. To affix glass chimneys to these, three narrow strips of metal are to be soldered at equal distances apart, and radiating out from the upper plate; the ends of these pieces are to be bent up, and
made to hook inwards, to receive and support the glass chimney. The lower edge of the glass has a rim, projecting outwards, by which it is to be held by the metallic hooks. In order to admit of fixing it in its place, a notch is left in the glass rim, which may then be placed under two of the hooks, with its notch over the third, when it is pressed down, and a small turn secures it.
This simple contrivance is certainly superior to the screw which is now frequently used to fasten the burners in their places, and which requiring to be screwed and unscrewed, is very liable to be out of order, and not unfrequently occasions the breaking of the glass.”
