ARTHUR ISAAC BLANCHARD, OF ISLINGTON, LONDON, ENGLAND.

VAPOR-BURNER.

Specification of Letters Patent.

Patented June 11, 1912.

Application filed December 4, 1909. Serial No. 531,310.

To all whom it may concern;

Be it known that I, ARTHUR ISAAC BLANCHARD, a subject of the Kingdom of Great Britain, and residing at Islington, London, England, have invented certain new and useful Improvements in Vapor-Burners, of which the following is a specification.

This invention relates to vapor burners and has for its object to provide an arrangement therein whereby a fine delicatecleaner needle may be conveniently guided into the jet orifice without injury to the needle.

Another object is to provide a convenient and efficient means for holding and reciprocating the needle without obstructing the flow of gas to the orifice and without the possibility of leaking where the operating means passes to the outside for manipulation. To this end I have provided a housing to which the cleaner needle is secured so as to permit lateral movement, the housing being movable in a guide which is spaced from the lamp frame so as to permit the passage of the gas to the orifice, a special gas-tight packing being provided where the manipulating means for the movable housing passes out from the burner.

In the accompanying drawing, Figure 1 shows a vertical central section of a lamp arranged according to this invention, Fig. 2 is a horizontal sectional view taken on the line 2, 2, of Fig. 1 looking downwardly, and Fig. 3 is a detail vertical sectional view on an enlarged scale and taken on the line 3, 3, of Fig. 1.

Like reference characters indicate like parts throughout the several figures of the drawing.

Referring more particularly to the drawings, reference character A designates the cleaner needle which is mounted at the free end of alight and flexible cleaner rod B arranged within a housing C and attached thereto, as at C, by the end B in such a manner as to permit a limited lateral movement to the cleaner needle A independently of the housing C.

The housing C is mounted in the guide D held in place by radially projecting. fins D, the longitudinal axis of the guide being in alinement with the jet orifice E, so as to guide the cleaner needle A when the latter is in central position into the jet orifice, the cleaner needle being constrained to pass into the jet orifice by the conical walls of the cup F surrounding the jet orifice (see Fig.

3) in the known manner. When the housing C is moved longitudinally toward the jet orifice, the cleaner needle A can be easily guided into the jet orifice, as the cleaner rod B is very flexible, even though the guide D be not in perfect alinement with the jet orifice. This longitudinal movement of the housing C is effected, for example, by means of a pinion G (see Fig. 1) engaging the rack H 011 the housing C (see Figs. 1 and 3) the pinion Gr being mounted on a spindle I passing outside of the burner and provided with a milled head J or other suitable means for rotating the same for communicating motion to the housing C for operating the cleaner-pin.

An air-tight fitting is provided for the spindle I where it passes through the wall of the burner. This fitting, as illustrated, comprises a long uniform bearing M ending in a round shoulder O which is formed gas-tight by grinding or otherwise, the spindle I being provided with a correspondingly rounded shoulder P, the parts being held in position by means of a nickel spring R. In the example illustrated, the part I of said spindle is of smaller diameter than the main part of the spindle and is attached to the shank S of the milled head J; and this shank S is provided with a flange S between which and the shoulder O the spring R is located.

The end B of the rod B is held in place by being screwed in to the end O of the housing C It is particularly understood that the details of construction of this device may be greatly varied without departing from the spirit and scope of the invention as defined in the appended claims.

I claim as my invention:

1. In a vapor burner, the combination of a nipple having a jet orifice and a conically walled cup surrounding the orifice, a guide in alinement with the orifice, an elongated casing movable in the guide, a flexible cleaner-rod partly within the secured at its inner end in the casing and extending the full length of the casing, and a fine delicate cleaner needle mounted on the free end of the flexible cleaner-rod.

2. In a vapor burner, the combination of a nipple having a jet orifice and a conically walled cup surrounding the orifice, a guide in alinement with the orifice, an elongated casing movable in the guide, a flexible casing and cleaner-rod partly within the casing and secured at its inner end to the casing and extending the full length of the casing, a

fine delicate cleaner-needle mounted on the free end of the flexible cleaner-rod, and means for moving the elongated casing.

3. In a vapor burner the combination of a lamp frame, a nipple screwed into the lamp frame and provided with a jet orifice and a conical cup surrounding the orifice, a guide held fixedly in said nipple and having radial fins on its exterior for holding the same in place, a housing longitudinally movable in said guide, a cleaner needle in said housing and adapted to be guided into said jet orifice by said conical cup, and means for longitudinally moving said housing.

4. A vapor burner, comprising a vapor chamber having its wall provided with a bearing bore having a uniform part and a round shoulder terminating said part, said Vapor chamber having an orifice, a cleaner needle for the orifice, a movable part provided with a rack and carrying said needle,

a spindle passing through said bearing and Copies of this patent maybe obtained for five cents each, by addressing the Commissioner of Patents, Washington, D36.
