GAS AND AIR MIXER.
SPECIFICATION forming part of Letters Patent No. 422,299, dated February 25, 1890.
Application filed March 12, 1887- Seri'al No. 230,709. (No model.)
To all whom it may concern:
Be it known that we, JOHN W. DANFORTH and ROBERT W. CLARK, both citizens of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Gas and Air Mixers, of which the following is a specification.
The object of our invention is to provide means whereby the amount of air and gas can both be regulated independently without interfering with the action of the other, and also a means whereby a finer adjustment of the gas is provided for and whereby the gas-adjusting device is protected from outside interference, all of which willbe fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal central section cutting through all except the pointed gasregulating device. Fig. 2 is a section through line X X, Fig. 1. Fig. 3 represents a central sectional view of our improved device connected to a sunflower-burner.
This improvement consists of a hollow case havingafiaring chamber d, and a smaller end (1 provided with an interior screwthread adapted toreceive the pipe 6, leading to the burner, which burner is not shown in the drawings, as it is not a part of this invention. Extending centrally across the flaring mouthpiece, just over the chamber cl, is a cross piece or brace f f, all these pieces being formed in one piece. In the center of the brace f f, projecting inwardly from the cross piece or brace, is a central collaror hub f. This collar is screw-threaded on the inside of the opening through it, so as to adapt it to receive the screw-threaded end of the tube a, into which it is thus rigidly secured, which tube when in place, as shown, extends to a central vpoint within the chamber d, the tapering end a extending into said chamber. On the tubular portion'is an inlet portion a, connected at right angles to the tube a, and through which the gas passes to the main tube. The opening through this tube a extends down to near the end of the tube of the same diameter and then contracts with a comparatively short taper to a smaller opening. The opposite end of this opening is provided with an interior screw-thread adapted to receive the screwhead I) of the needle-pointed bar I). This pointed bar I) is provided with a pointed end 17 of a sharper taper than the opening through which it passes, so that when it is adjusted in far enough to close the contracted opening of the tube a the closed portion is close to the end of the tapering portion a thereby leaving an open space all around the tapering cavity above the point of contact at the end a This construction is important, because the gas has a more free and finer outlet, as the opening is always an annular space at the end of the tube a. The screw-head b is provided with the usual cross-slot to receive a screwdriver for turning it and adjusting the bar 1). Over the'headbis a screw-cap Oto protect the bar b from outside interference when adjusted.
On the tubular portion cular disk g, adapted to be moved to or from the flaring mouth-piece of the chamber (1'. It is provided with a collar g and a set-screw 9 for securing it at any point to which it may be adjusted.
The object of the disk g is to provide means for adj ust-ing the amount of air admitted, which may be done independently of the adjustment of the tapering pointed bar I), so that when the bar is adjusted properly the quantity of air can be nicely adjusted without in any way disturbing the rest of the device.
WVe claim as our invention- 1. In a gas and air mixer, the combination, with a flaring open-n1outl1edcase having a cross-brace f f across the mouth of the same, and a central collar or hub f, of a tubular portion a, rigidly secured to the collar f, and provided with a cap 0, covering the gas-adj usting device, a disk 9', mounted on the tube a so as to be adjustable to or from the flaring mouthpiece, and a set-scrcw for securing it at any point when adjusted, a rod 1), provided with a tapering point b and with a screw-threaded head 1), adapted to screw into the top of the opening through the tube a for adjusting the bar I), the tapering point 19 of which projects through the opening in the portion a substantially as and for the purposes described.
2. In a gas and air mixer, a flaringmouthed case having a cross brace extending across the mouth of the same, and provided with a a is mounted a circentral supporting-collar, in combination with a tubular portion a, rigidly secured to the cross-brace so that its tapering end projects into the chamber d, the opening through said tube extending through to near the portion a of the same diameter and then tapering to a smaller opening at the outlet, an adjustingdisk 9, mounted on the portion a, a screw-cap C at its opposite end, and a gas-adjusting bar I), provided with a screw-head b, engaging with a screw in the opening in the tubular portion a, and provided with a tapering end 6 having a finer taper than the opening in which it passes, substantially as and for the purposes described. 15
