ROBERT W. CLARK, OF BUFFALO, NEW YORK.
GAS AND AIR- MIXER.
SPECIFICATION forming part of Letters Patent No.470,862, dated March 15, 1892.
Application filed April 1,1890- Serial No. 346,209- (No model.) i
To aZZ whom it may concern:
Be it known that I, ROBERT WV. CLARK, a citizen 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 my invention is to provide the means for more thoroughly mixing the gas and air and at the same time regulating the proportion of each before they enter the burner, all of which will be fully and clearly hereinafter describedancl claimed, reference being had to the accompanying drawings, in which I Figurel is a front elevation of the mixer, showing a cross-section through line 0 d, Fig. 3. Fig. 2 is a sectional elevation. Fig. 3 is a Vertical longitudinal section through line a b, Fig. 1.
In said drawings, 1 represents the usual hollow case having a flaring open-mouthed chamber 2 and an interior screw-thread 3 to connect with a pipe leading to a burner, which is not shown in the drawings, as it is not a part of this invention. A cross piece or brace 4 (shown in Figs 1 and 2) extends across the flaring mouth-piece and is rigidly secured to it or is cast in one piece with it. In the center of the cross-brace 4 is an enlarged portion or hub 5, having a circular hole through it into which the gas-tube 6 passes and is secured by the two screws 7, which pass through the flange 10 and then screwinto the cross-brace 4 at the points 8 to tighten the gas-tube in place when adjusted to the point desired. These screws 7 are each provided with a screw-driver head 7. The operation of these screws 7 is such that when the flange 10 is adjusted to the right point the screws are put in and pass first through screw-threaded holes in the flange l0 and then through similar holes in the cross-brace 4 without'disturbing the flange 10 from the case 1, and are screwed in until their heads come against the flange 10, against which they bind and become rigidly fixed, so that the flange 10 is securely held in any position it may be adjusted to or from the case 1, substantially as shown in Fig. 2.
At the side of the gas-tube is the inlet-pipe 9, made in the usual may. Below the inlettube isthe outwardly-extending flange 10,
which is either rigidly attached to the tube 6 or is formed in one piece with it. The object of this flange 10 is to provide the means for regulating the admission of air, which is done by the screws 7 and slipping the tube 6 to the desired point into the hub 5 and then tightening the screws against the flange, as above mentioned. This construction affords a more ready and convenient wav of adjusting theamount of air admitted and is cheaper and more easily constructed. The inner end of the gas-tube 6 is provided with aflaringopening 11, (see Fig. 2,) and the gas-regulating bar 12 is provided with a conical or enlarged end 13, adapted to fit the flaring opening 11. The opposite end of the gas-regulating bar is provided with a screw portion 14, having a countersunk or screws into a correspondmg screw-thread 1n the end of the gas-tube 6, over which is placed a protecting cover 16, the object of which is to protect the device when adjusted by means of a screw-driver and the countersunk or slotted head 15. The gas-regulating bar has to be put in from the outlet end of the gas-tube on account of the enlarged end 13.
In Fig. 2 I have shown a slightly-different form of the enlarged or conical end 13 of the adjusting-bar 12 by extending it in the form of a straight cylindrical portion l3 and extending correspondingly the barrel 11 at the end of the flaring opening 11. This construction affords a more complete and thorough mixture of the air and gas before it enters the burner, and consequently produces a more perfect and complete combustion and with less noise.
I claim as my invention- In a gas and air mixer, the combination of a flaring mouth-piece 1, provided with a crossbrace 4, a gas-tube 6, provided with an outwardly-extendin g flange l0, rigidly secured to or cast in one piece with it, and having the portion beyond the flange adapted to pass easily into the opening in the cross-brace, and screws 7, passing through the flange 10 and brace 4 for tightening it in position when adjusted, substantially as described.
