Claims2
A firebooster device which comprises:
- (a) a casing having an air inlet at a rearward end and an air outlet at a forward end;
- (b) a motor with shaft mounted within said casing aligned with said outlet port;
- (c) a blower fan mounted on said shaft;
- (d) a handle affixed to said rearward end of said casing aligned with said motor shaft;
- (e) a motor switch mounted within said handle and electrically connected in a circuit to said motor so as to turn said motor on forcing air through the air outlet port of said casing;
- (f) an elongated hollow extension sleeve slideably disposed on said air outlet port to guide the forced air directly onto a source of fire;
- (g) means for adjusting automatically the position of said sleeve on said outlet, whereby said means comprises:
- (h) said extension sleeve having a rear flange, said extension sleeve being slideable on the air outlet of said casing;
- (i) a solenoid with an actuating arm;
- said solenoid mounted within said casing so that the actuating arm extends outwardly and forwardly through said casing connected to the flange on said extension sleeve;
- (j) a spring disposed on the actuating arm of said solenoid between said casing and the flange of said extension sleeve;
- and
- (k) a solenoid switch mounted within said handle above said motor switch, said solenoid switch being electrically connected in the circuit to said solenoid so as to activate said solenoid to slide said extension sleeve on the air outlet port of said casing whereby said extension sleeve can be adjusted to various lengths thereon.
