FAN FOR DIS- iNFEOTlNG PURPOSES.
SPECIFICATION forming' part of Letters Patent No. 757,684, dated April 19, 1904.
Application filed July Z1, 1908. Serial No. 166 ,1145. (No mudelr) prevent the pressure in the reservoir from becoming too high or to maintain the same at a predetermined pressure, a safety or reducing valve 17 is provided. The, spring 18, which presses the valve-head 19 into its seat, may be `adjusted by screwing the abutment 20 in or out. Y
From the foregoing the operation of the apparatus will be readily understood. The reservoir 8 having been filled through a suitable filling-orifice 21 until the same is about half full, the current is turned on, and the fan begins to rotate. At the same time the shaft 10 and its crank are revolved, thus reciprocating the piston 13 of the compressor, which forces air into the space above the liquid inthe reservoir. The liquid immediately ascends the conduit 7 and from there is delivered into the rotating shaft 2, from which it is discharged as a line spray at the oritice L1. The spray is immediately seized by the blast of the fan and being still further divided is carried by the currents of air from the fan into all parts of the room. 4
It will be seen that my invention provides a convenient way of distributing vapor throughout an apartment. By this means a roornsuch as, for example, a public auditoriummay be constantly supplied with disinfectant, Vdeodorizer, or Aperfume in a very effective manner. vThe air in the room will be at all times thoroughly charged with the vapor or minute particles, and the purpose of the same will thus be accomplished in a more satisfactory manner than by sprinkling the floors or walls with a volatile liquid orby exposing such a liquid in open receptacles. Other uses for the invention; will of course be suggested according to circumstances.
' The form herein shown venient but not the onlyT embodiment of which my invention is capable, and I therefore do T @ZZ whom t may concern.:
Be it known that I, WILLIAM W. ROSSITER, a citizen of the United States, residing in the borough of Brooklyn, city of New` York, county of Kings, and State of New York, have' invented certain new and useful Improvements in Fans for Disinfecting and other Eur-poses,` of which the following is a specification, reference being had to the drawing accompany- 1o ing and forming panrt of the same. The invention which forms the subject of my present application, while it pertains, broadly, to fans of any character, relates more particularly to electric fans commonly used for ventilation and other purposes. f
The object of the invention is toprovide such a fan with means for loading the air-blast with vapor or minute particles of liquid. This material may be a disinfectant which it is desired zo to scatter throughout the room in which the i fan is used or a perfume or any other liquid,
according to the object sought.
To thse ends the invention consists of the novel features and combinations hereinafter z5 described, and more particularly set forth in the claims.
Referring now to the drawing, which shows a convenient embodiment-of my invention, 1 indicates the standard and casing in which the operating mechanism of electric fans is usually located. The armature-shaft 2, upon which the fan-blad es 3 are mounted, is in the present case hollow or tubular and has at its outer end a constricted outlet-orifice 4. At the other 3 5 end is an inlet-orifice 5, to which is connected by a suitable coupling 6 a conduit 7 The latter extends to a point adjacent-the bottom of a reservoir 8, suitably supported ,in the bottom of the standard. On the armature-shaft 4o is a gear-wheel 9, which by a train of gears drives a crank-shaft 10, suitably journaled in the casing. On the liquid-reservoir is an air-` compressor 11, consisting in the present instance of a cylinder 12 and a piston 13, working therein. A pitman 14 connects the piston and the crank in the shaft 10. Suitable valves struction herein described; but
What I claim is- 1. In a fan or blower, in combination, a hollow shaft having an inlet-orifice, and having an outlet-orifice at the center of the rotating fan, a liquid-reservoir, a conduit connecting the inlet-orifice of the 15 and 16 in the piston and in the lower end of the cylinder enable the liquid in the reservoir to be put under considerable pressure by the reciprocation of the piston.
'In order to hollow shaft with the I regard as a con-` not consider myself limited to the exact con-YY f reservoir,means for driving the fan, and means for discharging liquid from the reservoir through the conduit, the hollow shaft, and the outlet-orifice, as set forth.
2. In a fan or blower, in Combination, a hollow shaft having an inlet-orifice, and having an outlet-orifice at the center of the rotating' fan, a liquid-reservoir, a conduit connecting the inlet-orifice of the .hollow shaft with the reservoir, an air-compressor connected with the reservoir, means for driving the fan, and means for actuating the compressor, as set forth.
3. In a fan or blower, in combination, a hollow shaft having an inlet-orifice, and having an outlet-orice at the center of the rotating fan, a liquid-reservoir, a conduit connecting the inlet-oriiiee of the hollow shaft with the reservoir, a reciprocating air-compressor con nected with the reservoir, a crank-shaft, a pitman connecting the crank-shaft and the compressor, means for driving the fan, and means for rotating the crank-shaft, as set forth.
4. In a fan or blower, in combination, a hollow shaft having an inlet-oriiice, and having an outlet-orifice at the center of the rotating fan, a liquid-reservoir, a conduit connecting the 'inlet-orifice of the hollow shaft with the reservoir, means for driving the fan, means for compressing air above the liquid in the reservoir, and means for maintaining a constant pressure therein.
