Specification of Letters Patent.

Patented April 23, 1907.

Application filed November?, 1905. Serial No. 285,545.

T all L11/"tom, 111 wml/y concern: Be it known that I, DELBERT COOLEY, a

citizen of the UnitedStates, and a resident of Galena, in the county of Cherokee and State of Kansas, have invented a new and Improved Gas and Air Burner, of which the following is a full, clear, and exactdescription.

. The object of the invention is to provide a new and improved gas and air burner for use in heaters, furnaces, and the like arranged to cause a thorough mixing of the gas and air previous to ignition of the mixture with a view to insure a complete combustion of the mixture, the arrangement also permitting independent regulation of the supply of gas and air according to the richness of` the gas.

The invention consists of novel features and parts and combinations of the same,

which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment ofthe invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.Y

Figure 1 is a sectional side elevation of the improvement, andFig. 2 is a perspective view of the gas-valve and the mixing-disk.

The mixing-tube A is adjustably secured said bracket extending from the angular end D of a gas-supply pipe D, connected at the terminal of the angularend D by a pipe E with a suitable gas-supply. Within the gasregulating-valve F3 is provided with aper-` tures F, arranged within the gas-supply pipe D, to allow the gas to pass from the same through the openings F4 into the gas-regu;D

lating valve F3. The outer portion of the gas-regulating valve F3` is pro vided with lengthwise-extending slots F5, through which the gas escapes from the inside of the valve Fs into the mixing-tube A, as plainly mcli- E cated b v the arrows in Fig. l. On the outer j end of the valve F3 is secured a mixing-disk G, extending transversely in the tube A and reaching to the inner wall thereof, the said disk having angularlydisposed varies to forni spaces between the edges of adjacent varies for the passage of the gas and air to insure a complete mixture thereof.

The air-entrance end of the mixing-tube A is provided with a flaring mouth' orji'lange A', opposite which is arranged a correspondinglyshaped disk H, held adjustable on the gassupply pipe D by the use of a set-screw I. Thus by loosening the set-screw I and moving the disk H neareror farther from the mouth A it is possible to regulate the amount of air passing into the mixing-tube A. By adjusting the rod F lengthwise in' the supply-pipe D, as previously described, an inward or outward sliding motion is given to the valve F3, so that the slots F5 extend more quently a minute regulation of the amount of gas passing into the mixing-tube A is had. Thus from the foregoin'g it will be seen that the amount of air and gas to be mixed within the tube A can be regulated independent one of the other, according to the richness of the gas, to insure the formation of a properlycombustible mixture of gas and air.

. It is understood that the air passing through the mouth A into the mixing-tube A comes in contact and mixes with the gas escaping through the slots F5, and this mixture of gas and air passes between the adjacent varies of the disk G, so that a further intimate mixture of the gas and airtakes place, to form a highly-combustible mixture to be burned at the outer end of the mixingtube A. i l The' device is very simple and durable 1n tively few parts not. liable to 'get easily out of order. y

Having thus described my invention, I. claim as new and desire to secure by Letters Patent- 1' g 1. A gas and air burner, comprising a mixing-tube open at one end for the admission of air and open at the other end for the discharge of the combustible mixture of gas,and air, a gas-supply' 'pipe connected with a gassupply and extending into the said mixingJ tube, a tubular valve adjustable lengthwise in the inner end of the said gas-supplypipe, the said valve having gas-inlet openings withor less into the mixing-tube A, and cons'econstruction and is composed of comparain the gas-suppbT pipe and slots opening into l the said mixing-tube, and a mixing-disk E air and open at the other end `for the disf charge of the combustible mixture of gas and air, a gas-suppl}vv pipe connected with a gassupply and extending into the said mixingtube, a tubular valve adjustable lengthwise in the inner end of the said gassupply pipe, the said valve having' gas-inlet opening` Within the gas-supplyT pipe and slots opening into the said mixing-tube, a mixing-disk Within the mixing-tube having angularlydisposed vanes for the passage of the gas and air to insure a comple te mixture thereof, and a llanged adjustable disk opposite the flanged air-entrance end ot' the said mixing-tube.

In testimony whereof I have signed my name to this speeiiieation in the presence of two subscribing Witnesses.

DELBERT COOLEY.
