UNITED STATES PATENT OEEIoE.

JOHN H. IRWIN, OF PHILADELPHIA, PENNSYLVANIA.

LAMP-BURNER.

Specification forming part of Letters Patent No. 99,443, dated February 1, 1870.

cone, of a perforated guide or support, which acts as a guide to place the cone and shield in proper position and hold them there.

In the accompanying drawings, Figure 1 is a perspective view of my invention; Fig. 2,

. same with cone and shield removed; Fig. 3,

vertical central section of Fig. 1 with the oilreservoir added.

This invention relates to an improvement in the construction of burners designed to be used in connection with an air-chamber above the oil-pot; and it consists in constructing the burner with an outer imperforate jacket fitted at its lower end to engage with a collar on the top of said air-chamber while the burner is fitted in the usual manner to a socket in the oil-pot, and the burner has therefore two supports.

It also consists in a mode of constructing the parts of the burner so that the said jacket or shield shall act as a gage to insure the proper relative position of the wick-tube and cone; and it further consists in the deflectingplate located at the top of the wick-tube.

That the construction and operation of this device may be fully understood, I will particularly describe it.

G is an air-chamber located above the oilpot, and through this chamber the air passes to reach the flame below the cone. Said ch amber G has a central orifice, which encircles the socket in the oil-pot, and said orifice is surrounded by the collar H, to receive the lower edge of the jacket of the burner, which thereby is supported not only in the oil-pot socket, but at the outer edge of the frame or jacket also, and is therefore more securely held in place than if supported by the socket only. I

The perforated frame or casing B is fitted at its lower extremity to a socket in the top of the oil-pot, and at its upper edge it expands outwardly and joins the jacket A at a. The wick-tube O and the ordinary wick-riser are both attached to the frame B in the ordinary way, and the cone A rises above the wick-tube in the usual manner.

I I represent screws, or their equivalents, which may be attached to secure the jacket A to the collar H, if it is thought to be necessary.

At the upper end of the wick-tube O, I attach a deflectingplate, D, by which the currents of air ascending from the air-chamber through the perforations in the frame B are turned away from the base of the flame and against the inner surface of the cone A, by which they are brought back to the flame at a higher point, as indicated by the arrows.

As a process of manufacture, it is more convenient to form the jacket A and cone A in one piece and separate from the frame B.

The shoulder a is fitted to the upper edge of the frame B, and, when the parts are in position, acts as a gage to cause the upper end of the wick-tube to come into proper position in reference to the slot F at the top of the cone. This is made necessary because it is practically very difficult to manufacture the oil-pot with the burner-socket located exactly in the center of the orifice surrounded by the collar H, and without an adjusting gage either the upper end of the wick-tube would be improperly located in respect to the slot F, or the opening in the top of the air-chamber would be imperfectly closed.

Having now described my invention, what I claim as new is- 1. A lamp-burner provided with an outer imperforate jacket, A, fitted at its lower edge to engage with a collar, H, or its equivalent, to give the burner two supports, as set forth.

2. The jacket A and cone A, formed of one piece, with a shoulder, a, in combination with the perforated frame B, fitted to said shoulder for the purpose of gaging the adjustment of the wick-tube, as set forth.

3. A burner with a jacket, A, cone A, and deflecting-plate D at the top of the wick-tube, all constructed and arranged substantially as described.

4. A burner constructed with the jacket A and perforated frame B, substantially as described, in combination with the air-chamber G, provided with a collar, H, or equivalent,

as set forth.
