The parts 21 and 22 are provided with openings 24 which may be caused to register more or less closely so as to regulate the amount of air admitted to the fan chamber.

2 and 3, the damper member 15 comprises outer and inner relatively adjustable members 21 and 22 which may be secured in relatively adjusted positions by means of the bolts 23. Between the nut 17 and the end of boss 19 on the inner face of damper 15 is a screen 18 whose function is to prevent children and others from pushing anything through the openings of the damper and into the fan compartment. The damper member 15 has screw-threaded connection with the outer end of member 14 and is held in relatively adjusted position by means of the nut 17. This damper member is indicated in general by the numeral 15.Ī nut 16 on the screw-threaded member 14 screws against the cross bar 12 and secures these two in relatively adjusted position. In the wall 9 of the compartment 8 and opposite the open end of the fan is a sleeve 10 having a flange 11 which rests against the outside of the wall 9.Įxtending across this sleeve is a bar 12 having substantially midway of its length an enlargement 13 provided with a screw-threaded opening for the reception of the correspondingly threaded member 14 by which the damper member is carried.

On the shaft 8 of the motor 3 is mounted a fan 7 which is contained in the compartment 8 provided with a cover not shown herein but bearing the number 20 in the application identified above. These practically eliminate transmission of vibrations from the motor to the base, air tube 4, furnace, and house. As disclosed in my prior application referred to above, the main and auxiliary bases are connected only by resilient cushions at the four corners of the auxiliary base. The air conduit 4 which surrounds the fuel nozzle and electrodes and carries the air to the point of combustion is also carried by the main base I, as is the switch box 5. Mounted on a main base I is an auxiliary base 2 which carries a motor 3. Reference will now be made in greater detail to the annexed drawing for a more complete description of this invention. 3 is a fragmentary elevation designed to illustrate the relationship of the parts of the damper. 2 is a substantially horizontal section through the damper mechanism Fig. 1 is a plan view of a burner unit embodying my present invention, with the cover of the fan removed to show the relationship of the damper mechanism to the fan Fig. In the drawing annexed hereto and forming a part hereof, Fig. My invention further resides in the combination, construction 0 and arrangement of parts illustrated in the accompanying drawing and, while I have shown therein what is now considered the preferred embodiment of this invention, I desire the same to be understood as illustrative only and not to be interpreted in a limiting sense. This invention comprises such further objects, advantages, and capabilities as Will hereafter appear and as are inherent in the construction disclosed herein. The primary purpose of this invention is to provide readily adjustable control means for the air admission opening to the burner fan to provide means for the purpose stated which is so constructed that the amount of air admitted may be regulated with nicety from a small minimum to a large maximum.
