WALTER E. HUENEFELD, or CINCINNATI, OHIO, ASSIGNOR T0 TIE-IE HUENEFELD COMPANY, OF CINCINNATI, OHIO HYDROCABBON-BURNER.

Application filed September 6, 1912.

To all whom it may concern:

Be it known that 1', l/VAL'rnn E. I-IUENEFELD, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon- Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hydrocarbon burners and more particularly to such as are adaptable for use with oil stoves ,-the object of my present invention being to provide simple and eflicient means for raising and lowering the parts forming the combustion chamber member and for locking said parts in their normal lower position and sustaining the same in elevated position over the wick carrying member of the device.

With this object in View, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional view of the device with the parts in their normal operative position. Fig. 2 is a similar view showing the parts forming the combustion chamber, in elevated position. Fig. 3 is a transverse sectional view, on the line ww of Fig. 1, and Fig. 4 is a transverse sectional view, on the line y-y of Fig. 2.

The wick-tube member of the device comprises two concentric tubes 1-2, separated sufliciently to form a wick chamber between them, the lower end of said chamber being closed in any suitable manner. The nipple 3 is secured to the outer wick tube 1 for attachment to a supply pipe and this nipple communicates with the lower portion of the wick chamber. The upper end of the outer wick-tube is provided with an outwardly projecting annular flange t which is depressed somewhat, forming an annular rib 5 at the upper Xtremity of the tube 1. The inner wick tube 2 is provided with a depressed inwardly projecting flange 6 (the inner edge of which may be bent downwardly as at 7), and an annular rib 8 is thus formed at the upper extremity of said inner tube 2. A wick 9 is located within the Specification of Letters Patent.

Serial No. 718,936.

wick chamber between the tubes 1 and 2 and.

provided with a perforated metal wick holder 10. A hollow boss 11 is located on the outer tube 1 and communicates with the wick chamber and from this boss, a tube 12 projects in a diagonal direction,-said tube 12 and boss 11 constituting suitable bearings and housings for a shaft 13 which carries a toothed wheel 14L located within the boss 11 and adapted to mesh with perforations of the wick holder for raising the wick when the shaft 18 is turned in one direction and for lowering said wick when the shaft is turned in the other direction. A suitable knob or wheel 15 is secured to the free end of the shaft 13 to facilitate the manual operation of the wick raising and lowering devices. By so forming the upper ends of the wick tubes 12 as to provide an nular' ribs adjacent to the wick and separating the upper end of the latter from the flanges 1-6, any charred portions of the latter can be readily removed without becoming lodged in the immediate vicinity of the wick and thus the burner can be easily kept clean.

The annular flanges at the upper ends of the wick tubes 1 and 2 constitute seats for the lower ends of spaced foraminated shells 16 and 17 which form a combustion chamber 18 between them, said shells constituting the major portion of the combustion chamber member of the device.

The shells 16-17 are surrounded by a casing 19 which is spaced from the outer shell 17 and is open at its upper end,the lower end of said casing being provided with an inwardly projecting bottom flange 20 having a plurality of perforations 21. The upper end of the shell 16 may be pro vided with a fixed cap or head 22 having suitable perforations and the lower end of said inner shell may be provided with a perforated cap 23. The shells 16 and 17 and the casing 19 may be held in proper relation to each other by means of transverse rods 24L which pass through them.

A spider 25 comprising a plurality of radial arms, is fixed within the inner wick tube 2 and constitutes a part of the raising, lowering and locking means for the combustion chamber member of the device. A cylindrical portion 26 depends from the inner shell 16 or from the lower cap 23 thereof and enters the cylindrical space "formed by notched at its lower end to form a seat 29' and a stop 30. One of the legs 27 is provided above its lowerend with a horizon- .dependmg from the combustion chamber tal elongated slot 31 so that this leg will be made approximately L-shaped or hooked shaped.

When the shells forming the combustion chamber member are in their normal operative positions, they will be supported up on the annular flanges at the upper endsot' the wick tubes 1 and 2 and the legs 27 will be disposed between the arms of the spider 25 but Without actual contact with the latter. When the shells l6 and 17 shall have been thus disposed, the combustion chamber member with its cylindrical extension 26 can be turned so that one of the arms of the spider will enter the elongated slot 81 inone of the legs 27 and the parts will then be locked against vertical movement. By making the slot 31 of appreciable length, the shells 1617 can be partially rotated back and forth until they shall have become accurately seated upon the annular flanges of the wick tubes 1 and 2 and thus prevent any detrimental air currents. entering in close proximity to the upper end of the wick. The casing 19 is provided with a suitable knob or handle 82 for manipulating the combustion chamber member, to raisethe same above the wick or to lower said combustion chamber member as will now be explained. Assuming that the shells l6 and 17 are resting upon their seats on the wick tubes 1 and 2 and it is desired to raisesaid shells; the operator will turn said shells and casing and the beveled edges28 of the legs 27, riding on the arms of the spider 25, will cause said shells and casing (which compose the combustion chamber member) to rise and when the seats 29 shall have become disposed upon the upper edges of said arms of the spider, the combustion chamber member will be supported in its raised position above the wick. The stops 30 at the lower ends of the legs 27 will engage the arms of the spider and prevent the combustion chamber member from being turned too far. After the wick shall have been lighted,the operator-will turn the combustion chamber member in the reverse direction far enough to move the seats 29 OK or the arms of the spider and then the weight of the parts will be suflicient to cause said combustion chamber member to move downwardly and become seated at the upper ends of the wick tubes. By further rotation of the combustion chamber member the cylindricalguide portion 26 will be partly rotated and its L-shaped leg will be caused to cooperate with one of the arms of the spider to lock the'combustion chamber member against vertical movement.

Having fully descrlbed my lnventlon what a I cl'aim'as new and desire tosecure by Lettors-Patent, is:

' 1. Ina hydrocarbon burner, the combination with a wick. tube member and a combustion chamber member, of an extension 'member, said extension forming a guide for the combustion chamber member, said extension having a plurality of inclined edges,
