Description
Sept. 3, 1963 H. NAJlMlAN, JR., ETAL 3,102,483
VENT FAN AND BILGE PUMP Filed April 28, 1961 2 Sheets-Sheet 2 United States a n This invention relates to a combination bilge pump and ventilator for marine use.
- Particularly in boats having closed engine compartments, the presence in the bilge of combustible hydrocarbons such as oil or gasoline is a serious fire hazard increased by the presence-of gasoline vapors in the compartment. It is desirable to eliminate both the liquids and the Patented Sept. 3, 1963 connect the housing sections to the motor to position the motor and hold the housing sections together upon*pack-,
Each housingsection has an im'pellerchamber 20 separated :from the motorchamber 7 by the partition 14, in each case, Opening from'each such chamber are one or more sleeves'22, preferably tangential. A detachable cover plate 23, closes each impeller chamber;';20, 'and' retains ascreen 24 whichfisheld in place by the cover plate 23 when the latter is screwed to the housing. Each cover plate is centrally ported at 25.
vapors, along with any Water which may be in the bilge and to do this with a motor which is not exposed to'the explosive yapor. i f i To these ends, the present invention provides ahousing for a double ended motor, the housing being sealed about the motor shell and having sealing openings through which the two ends of the motor armature shaft project into upper and lower chambers. In these chambers the 'opposite ends of the motor shaft carry impellers respec- I tively designed for liquids and for gases, each such chamber having its own outlet.
A feature of the assembly consists in theconstruction ofthe, housing, which uses two identical housing com-W 'ponents joined centrally in mutually inverted relationship, the two components having cavities which together provide the motor compartment, each section of'the housing having its own impeller "compartment and tangential discharge port. The cover plates for the respective sec tions of the housing are interchangeable, desirably screened, and applicable to the respective housing sections in the same manner. Y 1
Connection of the respective housing sections to the motor shell not only seals these sections to each other, butalso positions the motor in its cavity. The chambers for the respective impellers are, however, desirably eccentric with reference to the axis of the motor armature shaft.
In the drawings: 'FIG. 1 is a view in side elevation of a device embodying the present invention.
FIG. 2 is a view taken in section on the line 2-2 of The motor is enclosed in a chamber 7 made by unitsection on line It will be noted that each chamber eccentric with reference to the axis of the impeller shafit 5, the eccentricity being designed to facilitate. discharge )of fluids through oncof the tangential outlet sleeves 22. At the upper end "of shaft 5 is impeller 21' of a type suitable for functioning as a blower for the discharge of air and other gases and vapors. v H
The lower endof the, armatureshaft 5 also mounts an impeller 30 but this impeller is" particularly designed to handleliquids, desirably being of shorter axial extent. The lower, chamber 20 and its tangential dischargeport or'ports (the sleeves 22) are identical with those above described, the housing section being the same part in inverted position. vLikewise the cover plate 23 may be. identical, However, in this instance, becausethe axial dimension of the impeller 30 is shorter than that of impeller 21, the impeller '30 does not so chamber. i v
The wiring 27 leading to the motor M enters one of the housing sections through a hole 28 sealed about the Wire by a grommet 29. The corresponding hole at 28 in housing section 9 may be closed by'a plug 29, if any .such hole exists. Of course if the hole 28 vwas bored specially in housing section 8,.there will be no correspond ing hole in housing section 9.
With the motor in operation, both impellers are operated to expel through the upper and lower tangential outlet ports the fluids acted upon by the respective impellers. Provision of twooutlets from each chamber facilitates any desired connection of a discharge hose such as those shown at 31 and 32. The unused 'outlet is closed bya plug, as at 3'3, 34. Other things being equal, the discharge would be arranged through the outlet toward which the respective rotor turns. However, this is not essential.
As noted, it is ordinarily desirable to ventilate the motor compartment at the same time that the bilge is drained. Accordingly, a single motor used as above described is a convenient means of achieving these two 0b? 1 jectives simultaneously.

The sections 8 and 9 of the housing 10 are identical.
However, they are assembled in mutually inverted relationship each provided with a transverse partition at 14 having bosses 15 and 16 against which the motor shell may seat. Studs 17 on the motor shell 6 extend through partitions 14 and have nuts 18 engaging the partitions to We claim:
