Contrivance For A Watch Lamp Perfectly Safe Which Will Show The


Hour of the Night, without any trouble, to a person lying in Bed.



It consists of a stand, with three claws, the pillar of which is made

hollow, for the purpose of receiving a water candlestick of an inch

diameter. On the top of the pillar, by means of two hinges and a bolt,

is fixed on a small proportionate table, a box of six sides, lined

with brass, tin, or any shining metal, nine inches deep, and six

inches in diameter. In the centre of one of these sides is fixed a

lens, double convex, of at least three inches and a half diameter. The

centre of the side directly opposite to the lens is perforated so as

to receive the dial-plate of the watch, the body of which is confined

on the outside, by means of a hollow slide. When the box is lighted by

a common watch-light, the figures are magnified nearly to the size of

those of an ordinary clock.
