v AU'TOMATICALLY-ADJUSTAIBLE MIXER FOR GAS-BURNER VALVES.
Specification of Letters Patent.
Patented Sept. 14, 1915.
Application filed March 4, 1915. Serial No. 12,151.
To all whom it may concern:
Be it known that I, ALFRED J. REEDY, a
lowing is a specification, reference beinghad therein to the accompanying drawings.
The invention relates to gas and air mixing devices for gas burners of the Bunsen burner type, the gas being delivered from a nozzle into a mixing tube of larger diameter. It is usual to provide the mixing tube with means for variably restricting the admission of air, so as to produce the proper mixture when the gas valve is open. If, however, the quantity of gas delivered to the nozzle is varied the adjustment of the air valve which is proper for the full volume of gas will not be right for use with the more limited quantity.
It is the object of the present invention to overcome this objection by providing means automatically operated by the gas valve for varying the air admission, so that in each position of adjustment there will be a proportionate volume of gas, and air.
It is a further object to combine this automatic adjusting means with a means for automatically changing the gas nozzle so that with a restricted discharge of gas the velocity is maintained by a corresponding restriction of the nozzle and a corresponding adjustment of the air admission.
In the drawings: Figure 1 is a longitudinal section through my improved construction; Fig. 2 is an end elevation of the air mixing tube and its controlling valve; and Fig. 3 is a plan view showing the connection between the gas and air valves. Fig. 4 is a section taken on line ww of Fig. 1.
A is the gas supply tube, B is the control valve preferably of the plug type and C is a nozzle through which the gas from the valve is discharged.
D is the mixing tube having the usual bell-shaped mount, and E is a cap for said tube having apertures F therein which may be variably restricted by a register slide G. This slide Gr is rotatively mounted upon a central pivot H, which is hollow for the insertion of the nozzle 0 therethrough.
The nozzle 0 is preferably provided with automatic means for adjusting its size in different positions of adjustment of the control valve. As shown, this is accomplished by forming a split inner nozzle I having a tapering end engaging a correspondingly tapered portion of an outer nozzle J, while the inner end of said inner nozzleis in operative relation to a cammed portion K of the plug valve. Thus when the valve is turned to a position restricting the flow of gas the inner nozzle I is forced by the action of the cam into the tapering outer nozzle J which will contract the orifice in the nozzle. On the other hand when the valve is wide open, the cam will relieve pressure on the inner nozzle permitting it to expand and enlarge the gas orifice.
For automatically adjusting the air valve G correspondingly to the adjustment of the gas valve I have provided the following construction: L is a fulcrum or pivot secured to the cap E, and M is a lever pivoted on said fulcrum and connected at one end to a link N, which at its opposite end is connected to a lug O on the stem of the valve B. The lever M is provided with a slotted outer end P, which engages a pin Q upon the register slide G, and the arrangement is such that a rotation of the valve stem B will cause a corresponding rotation of the register slide G, so that the quantity of air admitted is proportionate to the quantity of gas.
With the construction as described, when the valve is once properly adjusted and set it is possible'to turn the gas down or up without affecting the quality of the mixture. It is particularly desirable where the burner is to be used alternatively for low or high fire, and will avoid on the one the popping out due to an excess of air, or the smoky flame due to an excess of gas.
hat I claim as my invention is 1'. The combination with a gas cook, of a gas discharge nozzle projecting therefrom having its free end split, and longitudinally adjustable through rotative adjustment of the cock, and a member inclosing said nozzle having an outlet alined with that of the nozzle and having a portion of its interior surface tapered adjacent said outlet, longitudinal adjustment of the nozzle toward said outlet serving to reduce the passage through the nozzle through contact of the nozzle extremity with said tapered surface.
'2; The combination With a gas cook, of a nozzle pro ecting therefrom having its free end split, and means for exerting pressure transversely upon the split end of the nozzle to reduce its discharge area when the cock is rotatively adjusted toward its closed position.
3. The combination witha gas cook, of a nozzle projecting therefrom having its free end split, and a member having an outlet alined with the nozzle outlet and having a tapered surface adjacent said outlets, a relative longitudinal motion of said nozzle and said member being actuated by the valve when the same is rotatively adjusted, where- Gopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
through contact with said tapered surface.
4:. The combination with a gas cock, of a for increasing or decreasing the contraction of the nozzle proportionately as the cock:
is beingclosed or opened, an air tube into which said nozzle extends,and means actuated by the cock for varying the supply of air to said tube. V 1
In testimony whereof I affix-my signature in presence of-two witnesses. 1 i r Y ALFRED J 'REEDY, Witnesses: 1 r V V V ,P.'C. DE VoL, A. B. PURDY.
