BILGE PUMP:

.Ap1.v1ica:ioir'led October 1, 1921. Serial'No. 504,585.v

ToaZZ whom. t may concern:

Be. itknow-n that'I, HENRY HANsoN, a citizen of the United States, residing at Middletown, v4in the countyof Middlesex and 5f State of Connecticut, have invented'certain' new' andy useful` Improvements inl Bilge Pumps, of which thefollowing'is af speci lication, reference being had thereinito the accompanying drawings.

f This :invention relates to new and useful improvementsvin bilge pumps.

It is the'object of the invention,'among other things, to -provide a pump of thischaracter'that may be readily connected with and disconnected from the. propeller or other driving s haft, whereby the pump may be OperatedA at willi and from any part ofthe vessel, and tov produce ay selfcontained mechanism that may be set up and taken downzas a unit.r

. Among other arrangements andobjects .of

theinvention may be recitedAthe-provision of a device of the charactermentioned, with a View to fcompactness, in which the number yof parts-"are few, the construction simple, the

costi` off production small, and efliciency and operation high.

Tof these, and other ends, my invention consists inthe bilge pump having-certain de- ,30' tails of construction and combinations of parts-faswill be hereinafter described .and moreparticularly pointed out in the claims. Referring to the drawings, wherein like reference characters' designate-like parts in i the several' figures Figure 1 isa side elevation'fof my iinproved bilge pump with thepropeller'shaft in section and a driving gear thereon.

` Figure 2 ris a plan view thereof, the parts- 40' in section being upon line; 2 2 of Figure y1;

Figure 3 is a sectional elevation of the cylinderk and the laterally projecting lug and ball valves, taken generally upon line 3-3 of Figure 2; and

Figure 4 is aftransverse 'section' of the shaft, takenigenerally upon line 4 4 of'Figure 2.

' Bilgeipumps generally are ycontinuously operated from the propellershaft. 1t is not 0 necessary and in fact is not desirable that the bilge pump should operate during all of the time that the vpropeller shaft is rotating. Means havefbeen provided, however, for disconnecting the bilge pumps from the propel; ler. shaft but have generally been so designed as `to be more or less --complicated iii'A opera-L tion,.imposs1ble of operation under some conditions, frequently require the stopping member, reinforced by the rib 44and upon whichare'the standards 11-11 at one end andthestandards 12-12 at'the opposite end. Secured to the top of the latter standards, bythe screw 14 orsimilar means,- is the cylinder-lfhaving one closedend, and adjacent` thereto the radially projecting lugs 15 which are interiorly threaded at 16 with ball valves 17 of conventional form connected therewith. The cylinder is drained ofaccumulated water therein, when? desired, through an aperture in the underside of the rear end thereof,l normally closed by the plug 48.

yA plunger' 18 is-movable Within the cylinderand upon'the outer end of which is threaded a nut'19 containing a gasket. or packing, as may be most suitable.

Journaled within the standards 11y is a shaft 20 having thereon an eccentric collar 21, upon which is rotatably mounted the -gear 22 andan eccentric collar 23. This gear and vents endwise movement ofthe gear 22 and eccentric collar 23 thereon, and a pin 26 that passes therethrough, through the collar 21 and the shaft 2() provides convenient means for securing the eccentric collar 21, shaft 20 and the collar 25.

Encircling the eccentric collar 21 is the eccentric strap 27 which is split at 28, and by means of the screw 29 and nut 30 it may be held in proper frictional relation to said collar. This strap has a hinged connection with the plunger 18 through the pin 31. yA stop pin 32 that projects radially upon opposite sides of the shaft 20, contacts with a fixed stop 33 connected with one of the standards 11 to limit the movement of the shaft about its axis.

Rotation is imparted to the shaft 20 through the gear sector 34, journaled at 35, and having an arm 36 connected therewith, the teeth `of which mesh into those on the sector 37 that is adjustably and frictionally secured to the shaft 20 by means of the screw 33 connected with the integral ears 39. Any one of many other convenient means may be substituted for securing this sector, but it is desirable that it be so connected with the shaft as to be moved into various positions about the axis thereof, thereby accommodating the sector 34, which may, by reason of the construction of the vessel to which the )ump is connected, occupy a different anglle to the base member i() than that shown herein.

The propeller or other shaft from which the source of power is obtained to operate the bilge pump is designated 40, and connected therewith is a gear 41.

In Figure 1th@ pump is shown with the teeth of the gear 22 in mesh with those of the gear 41, at which time the plunger 18 of the pump is reciprocating within the cylinder 13, and the stop pin 32 is in contact with the fixed stop 33 in substantially the position shown by full lines in Figure 4.

If it is desired to stop the bilge pump, the arm 36 is manipulated so as to roclr the sector 34 upon its pivot mounting, thereby imparting rotation to the shaft 20 and all mechanisms connected therewith. This movement of the shaft 20 causes the eccentric collar 21 to travel about the axis of the shaft, and by reason thereof, the position of the gear 22 and eccentric collar 23 is shifted sufficiently` to disengage the teeth of the gear 22 from those of the gear 41 and thus separate the pump from its source of power. The pump parts now come to their rest position. at which time the stop pin 32 is againstwthe fixed stop 33 in substantially the position shown by the broken lines in Figure 4.

The arm 36, the upper end of which is shown broken ofi', may be operated either b y grasping the same or from any other por* tion of the boat by connecting it with a rope or in any other convenient manner well known in the art. The pump may thereby be set in motion or stopped from any part of the vessel. As all of the mechanisms are connected with the base member 10, the pump is assembled as a unit and secured by means 'of bolts or screws passing through the openings 42 therein. The ball valves and connections being integral with the cylinder it is merely necessary to thread a pipe in the end of each and the pump is ready for operation.

There are minor changes and alterations that may be made within my invention, aside from those herein suggested, and I would therefore have it `understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claims.v
