Description
Patented July 16, 1946 PATENT OFFICE} CQMBINED BILGE AND TANKWASHER AND JET PUMP Charles A. Winslow, Oakland, Calif. Application master 11, 1944, Serial No: 567,754
This-invention relates to an improvement in a combined bilge and tank washer and jet'pump. V
In the washing and bailing out of receptacles and particularly'in the washing and bailing out of the bilge from boats it is important that a small compact structure be provided which will operate either from a water service line, as when a boat is in dock, or'from the water pump forming a part of the power plant of'the boat. This struc- 2 Claims. (01. 103"262) ture must be' capable of' supplying an ample amount of waterfor thewashing operation and at the same time provide a jet pump assembly capable of discharging a maximum amount of fluid which may have accumulated in the bilge or which may be deposited in the bilge as a result of the washing operation.
The present simple and inexpensive device is capable of producing maximum jet pumping action and at the same time and without interference with the pumping operation is capable of discharging a regulated supply of 1 water for a washing operation.
More specifically, the present invention comprehends the use of a unit embodying two separate elements which when assembled provides the ejector pump structure and the water discharge for washing.
One of the primary objects of this invention is to provide a device of the type described in which the two units are so constructed that their manufacture is possible without the use of special machinery or equipment, thus reducing the cost and providing for replacements which can be utilized without special skill or equipment.
Reference will be had to the accompanying drawing forming a part of this specification and wherein like characters of reference designate corresponding parts throughout the several views,
in which:
Fig. 1 is a transverse section through the body of a boat showing the present apparatus arranged for use; I
Fig. 2 is a longitudinal vertical section of the assembled structure forming the essential parts of the invention, and
Fig. 3 is a section illustrating the nozzle control at the end of the wash pipe.
In illustrating this invention I have shown a boat body A having the usual spaced floor or decking B. The entire main structural unit of the present invention is illustrated by reference character C and to this unit is the connection D forming the fluid pressure line, the connection E representing the suction line for removing the iii accumulated fluid e, the discharge line F and the hose line G, the latter being the hose'for' supply ing "the washing water discharged through the adjustable 'nozzle H. 4
Referring now to Fig. 2, it will beseen-that the main unit embodies twoelementsQthe first being somewhat in the form of a nipple as "indicated by reference character I and having the threaded opening 2 and thelateral hose connection 3. An extension 4 is axially arranged with respect toth'e threaded opening 2, this extension being formed internally with the tapered jet opening 5 having the reduced tapered extremity to form the'fluid ejector when cooperating with the second part of the assembly. The nipple l is "formed with the reduced threaded portion- 5 iandthe shoulder 6 by means of which the" internally threaded pipe section! is connected therewith. The internally threaded opening 2 is provided to receive the coupling member 8 of the hose connection 9, by means of which the fluid pressure supply line D is connected. It will be noted that the coupling member 9 is provided with lateral ears ill to facilitate the making and breaking of the joint between these parts. The hose connection 3 receives the water discharge hose G and this hose can be further secured by means of the clamp II, as shown in Fig. 1. The pipe element 1 is reduced to provide the restriction I2 immediately forward of the jet nozzle l3 whereby the discharge of the nozzle creates suction in the pump line E. This line E is illustrated as a hose section and is secured in place by the hose clamp l4 shown in Fig. l. The end of the suction line or hose section E carries the strainer element IS in the usual manner, this strainer element preventing the closing of the hose by spacing the extremity of the same from the bottom of the tank or hull and further straining the discharging bilge water to prevent stoppage particularly at the restricted neck I: of the structure. The outer end of the pipe 1 is provided with a hose connection I6 for receiving the discharge hose F and if desired this latter may be clamped in place by a hose clamp such as shown at H or H.
The accumulating chamber I1 is shown as concentric with the jet opening 5 and the threaded orifice 2. This accumulative chamber is of such capacity as to provide a flow both through the jet 5 and through the hose connection 3 which latter is connected with the washing hose G.
It will be apparent from an examination of the structure heretofore described that all of the parts are generally of conventional commerical design to facilitate manufacture, that the parts can be readily separated and replaced for cleanor repair, and that by virtue of the structure and arrangement of parts the size of the assembly is such as to permit convenient storage.
It will be noted that the size of the jet is such that the entire flow from the water pressure line D will not be necessary to insure efficient opera- 1 tion of the bilge suction line E. Rather the size of the jet 6 is Such as to build up a back pressure so that-fluid is available fordischargethrough the washing line G; The end of the washing line G i controlled or regulated by the valve H shown more clearly in Figure 3, and this valve v can be used to control not only-the supplyr, of. a v
washing water but'also the amount of suction available at the nozzle I3. It is important-Ito note that the flow through thebilge 'suction' linef can be made directly proportionateto. the dis: charge through the-pipe G by manipulation of Qtus-J-iricluding a jet element having a central tubular body portion defining the outer wall of c an accumulator chamber, an outwardly tapered ietextendingaxiahy from one end of said tubuthe valve H at the end of this line. Thisiiis im 'portant in maintaining a constant operation when. desired and it is also important in that it permits anincrease or decrease of the overboard discharge as may be required in numerous variable conditions.
It'will be further obvious to artqthat the apparatus is capable of forming a permanent dischargemechanism of any capacity and that this discharge may be so regulated as toucompensate for any flow permitted through the line G whereby-a constant pumping operation is: available;
I'claim: l Y a 1.:A combined jetpump and washing apparatus including a jet element, said jet element having a tapered outwardly threaded jet at one end and an enlarged intake opening axially formed at the other end, an accumulator chamber formed between said jetand saidinlet, said one skilled mine lar'body and communicating therewith, said jet having-1 an outer threaded portion and an inwardly projecting annular shoulder defining one end wall of said; chamber, said chamber. bein formed with an internally threadedxportion, an inlet connection adapted for threaded engagement with said internally threaded portion and having its end wall. defining the other-end of saidchamber, a lateral outlet connectionproject- V a ing from said: chamber,;a flexible conduitincluding a manually regulated valveconnected with said outlet, an angle pipe member having an internally threaded-.-opening' axially formed with respect to one of its arms, for threaded engage..-
ment withsaid externally threaded jet, saidarm having, its passageway reduced medially to' cooperate with said .jet, and the other arm of said angle being adapted for connectionwith a suc'e tion intake connection.
