LAMP.

Patented April 6, 1909.

Serial No. 447,236.

To all whom it may concern:

Be it known that I, FREDERIC A. CURTIS,

a citizen of the United States, and a resident of Chicago, in the county of Cook vand State I of Illinois, have invented certain new and useful Improvements in Lamps, of which the following, when taken in connection with the drawing accom anying and forming a part hereof, is a ful and complete description,

sulficient to enable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to kerosene lamps using chimneys; and the principal objects of the invention are to obtain a lainp by means of which a large llame and one of great candle power may be produced, reference being had to the size of the wick eniployed.

A further object of the invention is to obtain a lamp the burner whereof is simple in construction, easily cleaned, readily trimmed, and not liable to get out of order.

A further object of the invention is to obtain a lamp the burner whereof is durable, uniform in operation, and economical in construction.

Other objects sought by me are disclosed in this description.

In the drawing referred to, Figure l is a side elevation oi a lamp, with the chimney and oil receptacle removed, embodying' the invention, with the dome of the burner turned back to expose the arts thereunder, which are shown in verticalpsection, to view. F ig. 2 is a front elevation of the parts illustrated in Fig. l, with the dome turned back. Fig. 3 is a vertical sectional view of the wick tube guard, and air deflector, which forni essential elements in a device embodying the invention. Fig. 4 is a top plan view of the wick tube guard of the device. Fig. 5 is a side elevation of a wick tube guard. Fig. 6 is an end elevation of a wick tube guard. Fig. 7 is a plan view of a blank from which vthe wick tube guard is obtained; and Fig. 8 is a lan view of a blank from which the air de ector of the device is obtained. 4A reference letter applied to designate a l given part is used to indicate such part 5 throughout the several iigures of the drawing, wherever the same appears.

A is the base of the burner of the device, and a is a foraininated table to base A.

; of which a chimney is held in position on the burner.

D is a wick tube.

E is a wick raising thumb wheel.

l? is an ordinary flat lamp wick. (shown in vertical section in Figs. l and 2), is an additional lamp wick, of the kind known as round lamp wicks. Tick F is drawn through wick G.

H is a washer on wick F, to prevent wick G, or any part thereof, from being drawn into the wick tube D when wick F is raised l by the turning of the thumb wheel E.

I is an air deflector which is placed on the foraininated table a so that some of the air which iiows up through the foraminations in such table will be thereby deliected into the flame from the wick Il, or into the vapor or gas from which the flame is obtained. Air deflector I is illustrated as made from a blank cutout of sheet metal, (see Fig. 8), and is obtained by taking two of such blanks and bending them up on lines i, i", and i to shape them and to join them together. Air deflector I is provided with aperture I for the passage of gas or vapor and air to the llame of the lamp, and the blank is cut away on line I to obtain a V shaped aperture at the ends ol' the air del'lector.

J is a guard interposed between thel wiek tube D, (to which it fits reasonably close) and the air deflector I. Guard J may be made from the blank illustrated in Fig. 7, and of sheet metal.

j, j, j@ are ears on the blank illustrated in Fig. 7 and to obtain such guard it is simply necessary to take two of the blanks and bend up the ears so that the ear j" on one blank will come between the ears j, y', on the other blank, and also to bend such ears so as to come a short distance along the sides of the guard. I'Vhen suoli ears are thus bent the ears j extend outsideot' ears 9,7', at the ends B is a dome, and C, C,.are springs by means of the guard, and the guard, When thus made, is of the right length to come into close contact With the ends ofthe air deiiector l. The ends of delector I are indented, both above and below/.the eaifsy", to hold the 7guard .and the delecti1l closely and firmly together, as one piece, W hen thus made the heat of the deflector I W-illbe conveyed by conduction to the guard J,

j, j are broken lines indicating the lines on which the blanks (illustrated in Fig. 8), are bent up to obtain the Wick tube guard J'.

Vthismeans a small generating chamber is obtained ac ljacent to the vvick F, and 'rriore ,of vthe Wick is `ferqi'osed midway betvveenthe edges thereof than is exposed at such edges.

Some of the functions or' the additional Wick are, to supply oil to Wick F, at the upper end of such Wick, in Jlarger quantity than earl b'fe eur-plied by le Single Het -Wleks peralter a Iportion 'of'tlli'e voil in the receptacle has been used. to permit the use `,of ia short Wick F.

To trim the Wick the air delector and the Wick tube guard may be removed and the Wick trimmed squarely across, near to the upper end of the'Wick tube (D), and the air deliector and Vguard then replaced by sliding v .the guard oyer 4the Wick tube. The guard fits to the Wick tube so closely that it is maintained in place by liriction, and the heat thereof is conveyed to the tube by conduction.
