Y SPECIFICATION forming part of Iietters Patent No. 418,782, dated January 7,1890.,
Application filed July 5, 1888. Serial No. 279.006. (No model.)
To all whom it may concern.-
Be it known that I, JOSEPH E. BOHNER, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a newand useful Improvement in Lamps, of which the following is a specification, reference'being had to the accompanying drawings, in which- Figure'l is a vertical central section. Fig. 2 shows a modification, and 1s a vertical section showing the wick-tube and central airsupply passage with the wick raising and lowering rod partly in'the wick-tube and partly in the airsupply passage O. Fig. 3 is a crosssection through the parts shown in Fig. 2. Fig. 4 represents a modification showing the rod for raising and lowering the wick located wholly in the wick-tube. Fig. 5 is a crosssection through the parts shown in Fig. 4.
My invention relates to that class of lamps which have Argand burners; and its object is to provide improved devices for raising and lowering the wick, which Iaccomplish by providing a lifting-rod which is connected at one end to the wick-holder, which is located in the wick-tube, from which wick-holder the rod passes either through an opening in one of the walls of the wick-tube or through a hole in the bottom of the wick-tube to a point where it can be reached by the hand.
Vhat I claim as new will be set forth in the claim.
In the drawings, A represents a lamp-fount.
B is the base of the lamp.
O is a tube which'forms a central air-passage.
o is the wick-tube.
D is the outer wall of the wick-tube, the inner wall being the tube C. This outer wall `D of the wick-chalnberis a tube, and the bottom of the wick-chamber is closed by an annular disk, as clearly shown in the drawings, leaving the central air-passageC open for the passage ofair from the bottom ofl the lamp to the interior of the ame.
b is a slot in the wall of the tube C near the upper end thereof.
c is a wick-holder located in the wick-tube, as usual.
E is a rod, bent as shown, one end of which 5o 4is secured to the Wick-holder c, from which,
wick-tube, then through the slot b, andthence down inside of the tube C to the base of the' lamp.
F is an air-space between the wall D of the wick-tube and the wall G of the fount.
d are passages from t-he fount to the wicktube,`as usua e is the button or flame-spreader, supported as usual.
I is a perforated cylindrical piece of sheet metal, the lower end of which is anged or turned outward, as shown at 71 and its upper end is provided with a perforated iiange t', turned inward, filling the space between the top of the perforated cylinder I and the cone II.
J is a perforated cup which iits into the lower endof the tube O. This .cup protects the lower end of the tube, and can be adj usted vertically to regulate the admission of air, if desired.
The other parts in Fig. l need not be described. As shown in thisl figure, the wick can be raised and lowered by means of the rod E, apart of it beinglocated in the wick-tube and part in the tube C, as before described. If the sloth extended to the top of the tube O, the i'lame would be liable to run down in the slot, and then some device would be necessary to protect the ends of the slot; but by inaking it, as described, terminating a little dis tance below the top of the tube, this trouble is obviated, and no additional provision to prevent the iiame from running down in the slot is necessary.
In Figs. 2 and 3 I have shown a modification which consists in providing a tube k 011 the inside of the tube C. Through this tube k passes that portion of the rod E which, as
shown in Fig. 4, passes directly down on the inside of the tube O. This tube 7c serves the office of a guide for that portion of the -rod rod or duplicate of E may be used, if desired.
The inverted frustum of a cone, in connection with the part I, performs a useful office in directing and distributing the air to the flame.
The lifting-rod passes to the Wick-holder either through a slot' b in one wall of the wiektube or through a hole in the bottom of the wick-tube. The tube j is secured at its lower end to the bottom of the Wick-tube, and extends up above the highest point of the oil and prevents leakage. I thus carry one end of the lifting-rod directly to the wick-tube and connect it with a Wick-holder therein. The other end of the lifting-rod is carried to a point Where it can be reached and operated directly by the hand.
Vhat I claim as new, and desire to secure by Letters Patent, is-
In alainp, a wick-chalnbera, which is closed at the bottom and is separate from the lampfount, the sides of the Wick-chamber consisting of the tube C and wall D, the tube C beingopen to allow air to pass from the bottom ot' the lamp to the inside of the flame, and a wick-holder located in the said Wick-chamber, in combination with a lifting-rod which is connected at one end to the wick-holder and passes from the Wick holder to and through one of the side Walls, or through the bottom of the Wick-chamber to a point where sueh rod can be reached and operated by the hand, substantially as and for the purpose specified.
