UNITED STATES PATENT FFICE.
AUGUST BUERKLE, OF ALLEGHENY., PENNSYLVANIA.
GAS-BURNER.
SPECIFICATION forming para of Letters Patent No. 637,849, dated November' 2s, 189e.
Application filed July 2 1898.
T0 LZZ whom, t may concer/2,:
Be it known that I, AUGUST BUERKLE, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Gas- Burners, of which improvements the following is a specification.
The invention described herein relates to certain improvements in gas-burners which are capable of general use, but are more especially applicable for use in water-heaters.
The invention has for its object a construction whereby a complete and eiective combustion of the gas canbe obtained and whereby an excessive and destructive heating of any of the parts, such as is liable to occur when the gas is turned down or the Haine reduced, is prevented.
In general terms the invention consists in the construction and combination substantially as hereinafter more fully described and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective View of my improved burner. Fig. 2 is a view partly in elevation and partly in section; and Fig. 3 is a sectional detail view, the plane of section being indicated by the line III III, Fig. 2, looking in the direction of the arrow a.
In the practice of my invention the distributing-chamber l, which may be of any desired shape, is provided with a series of nipples 2. A like series of tips 3, each having a small passage or opening 4 through it, are tted on the nipples 2. The tips are secured in the bell-shaped enlargements 5a, formed on the lower ends of the tubes 5. A series of openings 6 are formed through the diaphragms closing the ends of the bells 5a, said openings being arranged around the tips 3 and adapted to admit air, which will mix with the gas during its passage through the tubes. The upper ends of the tubes are provided with enlarged heads 7, forming expansionchambers for the reception of the mixed gas and air. These heads are preferably made removable from the tubes and to this end are provided with sockets S, adapted to tit over and be secured to the upper ends of the tubes.
Serial No. 684,998. (No model.)
A diaphragm formed of wire-cloth or iinely= perforated sheet metal is so arranged in the head that the gas will pass therethrough. Over this diaphragm is placed a cap or cover, so arranged and supported with reference to the upper edge of the head as to form a narrow slit or outlet for the escape of gas. The preferred construction consists of a cylindrical shell El, formed of wire-cloth or iinelyperforated sheet metal, which is arranged inside the vertical wall of the head, but at a short distance away from the wall, as shown in Fig. 2. The shell is held the desired distance from the vertical wall of the head by a bead or rib 10, formed on the bottom of the head and within which the lower end of the shell fits. As shown in Fig. 2, the shell 9 is made of sufficient length to project beyond the vertical wall of the head, and its upper end fits within a bead or rib l1, formed on the under side of the cap or cover 12. This cap is held in position on the shell by bolts 13, having their lower ends secured to the head 7, thereby clamping the shell in position. The cap is made sufficiently large to project beyond or overhang the head, thereby preventing water from dripping onto the shell.
It has been ascertained by experiment that when the vertical wall of the head 7 is omitted or relatively reduced, exposing the entire or greater portion of the perforated shell, so that when the gas is turned low the lame will be brought closely in contact with the shell, the latter will be heated to such a degree as to rapidly destroy it. By employing a shield such as the verticalwall of the head, arranged at such a distance from the shell as to prevent ignition of the gas until it passes above the shield, the flame will be in contact only with the portion of the shell above the shield and will not eect any excessive heating of the shell. This protection against excessive heating is due to the fact that the portion of the shell surrounded by the shield will afford a sufticiently-large radiating-surface to prevent the excessive heating of the uncovered portion. The space between the shell and shield should be sufcient to permit gas andair to flow through it to the slot or opening between the upper edge of the shield and the cap.
IOO
rIhe flow of air through the openings 6 is regulated by disks or plates 14, mounted on the tips 3 and having openings Which arel caused to register more or less with the openings 6 by shifting the disks or plates. The simultaneous adjustment of all the plates or disks is effected by a rod 15, connected to said plates.
The shape 0f the perforated plate and its shield is immaterial; but when the individual burners are arranged in circular order it is preferred that the perforated or burner plate should be made in the form of an oval shell, as shown.
By the employment of an expansion-chamber at or adjacent to the point of combustion the iiow of the gas through the perforatedshell is retarded, thereby affording opportunity for a more thorough mingling of the gas and air.
In testimony whereof I have hereunto set 35 my hand.
AUGUST BUERKLE.
