Nielsen, Darien, Conn, asslgnor to Nicholas J. Totalo Filed Nov. 1, 1963, Ser. No. 320,769 5 Claims. (Cl. 103-152) actuating linkage and the several pumping units operated by said linkage.

The various gravity actuated pumps previously proposed for removing bilge water from boats employ relatively expensive actuating means for operating the various pumping units of the pump. Such actuating means have included vertical type pendulums, rolling Weights, etc. In those devices that have utilized a horizontal type pendulum as the actuating means, a relatively complex means has in most cases been required for supporting the several pumping units and/ or for obtaining the eflicient valving of the latter.

One object of the instant invention is to provide a novel gravity actuated devicefor pumping bilge water from a boat whereby a very simple reliable and direct means is provided for efliciently supporting, valving and actuating several individual pumping units.

Another object of the invention is to provide an improved bilge pump having a horizontal actuating. pendulum and which has several pumping chambers and novel interconnecting linkages between the pendulum and the several pumping chambers respectively.

Another object of the invention is to provide an improved bilge pump having a plurality of radially disposed pumping units that are coupled in a novel manner to an annular member that is rotatably mounted on an eccentric portion of a vertical main drive shaft.

A further object of the invention is to provide a novel bilge water pump having a-plurality of individual pumping units actuatedby a horizontal pendulum, the pumping units having each a novel valving arrangement which will permit the lodging of foreign particles such as sand in the valve members, without causing a malfunction of the latter.

Other objects of the invention will become apparent as the disclosure progresses.

In the drawings: 7 V 7,

FIG. 1 is aplan view in partial section-illustrating one embodiment of the instant invention.

FIG. 2 is a vertical sectional view taken along section line 22 of FIG. 1.

Referring to the drawings, there is shown a pump frame 10 which is adapted to be suitably mounted in a boat and which comprises a horizontal rectangular base 11 having four

upstanding sides

12, 13, 14 and 15 secured thereto. A horizontal shaft supporting bearing or plate 16 is fixedly mounted on base 11 by means of four

vertical columns

17, 20, 21 and 22 and associated Allen type screws 23. A vertically disposed main shaft 24 is rotat ably mounted on the base 11 and plate 16 by means of

suitable bearings

25 and 26, hearing 26 being retained in an annular member 27 secured tobase 11. The upper end of shaft 24 is formed with a head 30 to which is fastened what will be referred to here as a horizontal pendulum 31 that includes a radial arm 32 and an actuator weight 33. As will be apparent when the pump frame 10 is tilted from a horizontal condition by a rocking motion of the boat, the pendulum 31 will swing through an arc to a low point determined by the direction of tilt and in so swinging will correspondingly rotatably actuate the main shaft 24. Rotatably fixed to an 3,190,230 Patented June 22, 1965 intermediate portion of the main shaft is a collar 34 that is eccentrically disposed with respect to the main shaft. Rotatably mounted on the cylindrical outer surface of collar 34 is a bearing 35, the flanged portion 36 of the collar serving to vertically support the bearing 35. Fixed to the outer portion of bearing 35 'is a connecting ring 37 having a radially outer flanged portion 40 formed there-' on. r

The instant bilge pump is provided with a pair of

pumping units

41 and 42, and in thatthe construction and operation of each of the units is similar, a detailed description of one thereof will sufiice here. The pumping unit 41 comprises a main radially disposed cylinder block 43 which is secured to the base 11 and which is formed with a cylindrical bore 44 therethrough. End sealing. plates 45 and 46 are secured by any suitable means to the respective inner and outer ends of cylinder block 43., Mounted for reciprocating movement'in the cylinder bore is a piston 47 that is fastened vto a piston rod '50 by means of a washer 51 and a nut 52, FIG. 2. A sealing connection is provided betweenthe piston and the cylinder block, such connection comprising a flexible telescoping tubular element. 53 that may be made of rubber, plastic or a similar material. One end of .the tubular element 53 is clamped in sealed relation between the inner end of the cylinder block and the'plate 45 while the other end thereof is clamped in sealed relation between the Washer 51 and the piston 47. The inner end of the piston rod 50 is articulately connected by means ofa pin 54 to the outer end of a connecting linkl55. The inner end of the link 55 is in turn articulately coupled by means of a pin 56 to the adjacent portion of said flanged portion 40 of ring 36. As may be readily seen when shaft 24 is caused to rotate by reason of a swinging movement of the horizontal pendulum 31, the eccentric collar 34 will cause ring 36 to partake of an accurate p'recessional type movement which in turn will produce through the articulate link 55 a reciprocatory motion of the piston 47 in the pumping cylinder.

, Suitable valving and fluid conducting lines are provided in the pumping unit 41. These include a water inlet passage 60 formed in the outer cylinder plate 46, said passage communicating at one end with the plastic water inlet hose or line 61 and at the'other end with a borel62 which opengrinto the pumping cylinder 'or chamber 63'. A one way flapper valve member is operatively disposed between the inlet passage 62 and the pumping chamber 63, said member. comprising a rubber like pad 64frnounted' at one side thereof by a screw 65 to the inner face of plate 46. The flexible valve pad is swingable towards and away from an inlet passage blocking position by differenable towards and away from an outlet passage blocking position shown in FIG. 1 by differential fluid pressures. Through the outer wall of the cap member 70, there is formed an outlet bore 73 which operatively communicates with a suitable exhaust hose or line 74. The inlet and outlet lines 61 and 74 are operatively coupled to those fluid conducting passages in the pumping unit 42 which respectively correspond to

passages

60 and 73 of the pumping unit 41. Lines 61 and 74 are also operatively coupled to the main inlet and outlet lines 75 and 76 respectively, the remote end of line 75 being disposed in the region where the boat bilge water has collected and the remote end of the line 76 being disposed over the 'side rail or rear transom of the craft.

f In the operation of the instantdevice; an intake stroke i (a displacement to the right 'as seen in FIG. 2) of the piston 47 will lower "the fluid pressure in the pumping V chamber '63 and such will cause valve 64 to open and valve 71 to close as'shown. This action will causerwater to be drawn into chamber 63 through lines 75, 61 and' passages 60 and 6;. When the piston 47 is dis placed; in the opposite direction through apumping stroke, the pressure in chamber 63 willincrease so as to cause valve 64 to water in chamber 63 to -be forced out through passages 66,267, 7 3 and

lines

74 and 76; By the repeated reciprocatory strokesof piston 47 caused by arcuate oscillations of the horizontal pendulum 31,water will be repeatedly close and valve-71 to open. This action willcausetthe pumped'frorn the main intakeline 7 5 into the main exhaust line 76. In this way the rocking motion of the'boat effectively operates the instant pumping device and thus' .prevents any appreciable amount of bilge water from accumulating in the bottomof the boat;

t It will be understood that the piston by means of'a link 55a, this arrangement being similar to that described above for piston rod 50 and link 55; andi that the operation ofpumping unit 42 will lag or lead V r0d'50a of the: pumping unit 42 is articulately connected to the ring 36 said flappertvalve members comprises a flexible pad that,

the operation of pumping unit 41 by 90 degrees depending'on which direction'the horizontal 'pendulum'31 happens to be swinging. v M It, should be understood that theforegoing disclosure relates only to'the preferred embodiment of the invention and that it is intended to cover all changes and modifica- V tions of the example of the invention herein chosen for illustrative purposes and which do not constitute dcparturesfrom the spirit and scopeof the'invention.
