Cdistinti (,Qtatee Olii NGE M. OHAMBERLAJN, OF NEW YORK, N. Y., ASSGNOR TO HIM- SELF AND GEORGE MOORE, OF SAME PLAGE.

Letters Patent No. 108,106, dated October l1, 1870.

IMPRCVEMENT IN LAMPS:

The chedule referred to in these Letters Patent and making part of the same Figure 2 is a side elevation of a slightly modified form of the same. Y

My iniprovement relates more particularly to those lampsin which some material-is used to hold theoil by absorption, such as the chlorides, with whicht-he oil-pot oi' the lamp may be filled. These absorbing substances are employed for the purpose of holding the oil in ease of accidental breakage ofthe lamp, so that the oil will not spread and set fire to the surrounding objects. lt has been 1found necessary, when absorbente have been used, -to employ a tube w-hich would prevent contact of thc wick and the absorbing material, and such tubes have: always hitherto been iliade a part oi' the burner, which was only capable of removal when the protecting-tube should be removed likewise. This ias been found to be objectionable, because- First, the insertion of the protecting-tube, when the oil-pot is filled with an absorbing material, is attended with ditiiculty.

Second, it necessitates the use ot' the particular style of burner manufactured with the tube, when said burner may be very inferior.

Third, to till the lamp with oil requires a separate orifice, or the inconvenience of removing and replacing the tube at each illing.

These objections, which are vital, are all obviated by my improvement, which, therefore, consists in placing within the protecting-tube, a cylindrical wielrtube, having an expanded top furnished with ascrewthread, to receive any style of burner which may 'ne preferred.

` The invention alsoembraces an air-chamber surn` rounding the wick-tube, by means oi which the oil- .pot lis kept cool.

That others may fully understand my invention, I will particularly describe it.

The tube B is provided, at its upper end, with a screw-Harige, which screws iutothc collar on the oilpot. lhc tube B should extend nearly or quite to the bottoni of the oil-pot, and is surrounded by the chloride, or other absorbing substance employed. It willnow be observed that when the tube B has been once inserted, and the chloride is around it, it will not be again removed so long as the absorbing material does not require to be renewed.

The tube B is closed at its bottom.

The tube E, opcn at both ends, is placed 1n the middle of the tube B, and extends through its bot-v tom, so as to eonununicatc with the oil-space, and a partitiointnbe, l), is placed between tubes B and E, so as to canse thc air to descend along the inner surface ot' B, and ascend to the burner along the outer surface 0i E.

The top of the tube E is expanded, and furnished with a screw-thread to receive the screw of any burner of' proper size which it may be desirable to use.

The tube E is made sntficicntly large to receive the wick from the burner without trouble, and the burner may be removed inthe ordinary manner when the lamp to be iilled, Ithe oil being poured down 4the tube E directly into the oil-pot.

From the above description, it will appear that my improyement is not an improvement in barriers, but

an improved safety-attachment to lamps, capable oi' usc with any lamp, and any style o'f burner. lhat when once applied it becomes a'ixtnre, while the burner may he put on or oli' as usual. That the lamp may be filled in the usual way, and without disturbing the absorbents. lhat the current of air passing to the burner will keep the lamp always cool. Having described my invention,

What I claim as new is "lhe wiel: and filling-tube 1'), constructed with a screwfthreiul at. its top to receive the burner, as set forth, combined with the tube B, as set forth,and for the purpose described.
