CORPORATION OF WASHINGTON PORTABLE POWER PUMP Application filed April 30,

My present invention relates to the pumping art. particularly to pumping equipment, which, because of its light weight and compactness lends itself to such uses as fighting 5 forest fires and which may be more specifically defined as a light weight portable power pump.

My present invention is an improvement in ertain details of my United States Patent No. 1,585,146 issued l 18th, 1926. As pointed out in my former application there is a great need for a pump of this general character and as the terrain on which this equipment is used is usually very rough and covered with heavy underbrush, windfalls and often slashings, a large number of fires occur at or near the scene of logging operations, This is due to the fact that a large number of men are employed, some of whom 20 are certain to be careless, and the fact that when a tree is felled the pitchy needles of its upper branches soon dry out and as they are waste and are left on the ground, act as much tinder when exposed to flame. It is unde one such as this that it is part a i ortant to have the various parts pump prot cted to an unusual des present application the general arrangement are shown in my cation, and the features claimed h will be more definitely pointed in the claim. are those details of conin the easily injured parts of L pamper are thoroughly protectedagainst accidental damage, th refore:

The principal object of my invention is to provide powerful pumping unit wherein the various easily broken or damaged parts are fully protected from accidental inji A further object is to so construct erta of my protective devices that the back pa ingof my device may be more easily, t and comfortably accomp shed.

A further object is to provide a pressure control device for the cylinder coolin A further objectis to provide a pain unit wherein the center of weight lies to the base thereof.

A further object is to provide constructional details that will make my pumping 1930. Serial No. 448,473.

ure 8 is a bottom plan view with my ,"tor plate partially broken away to betustrate certain parts.

Referring to the drawings throughout which like reference numerals indicate like by s, numeral 6 designates the main base member. This is provided with a plurality of members as 8 and 9, designed to give .c l stren and to better shield or certain garts.

Formed as part of base member 6 is the water pump intake 10. This I prefer to form as part of my base member. When so constructed the intake member is fully protected from injury, adds structural strength to the base member and reduces 'the total weight over a pump having the intake within the pump proper. This is ticcomplished by making the base of light weight metal such as cast aluminum, whereas the pump itself must necessarily be made of heavy metal as cast brass or iron. Another advatage of this 'unit construction is the reduction of the overall height. This is of considerable importance as to be readily carried on a mans back the center of weight must lie as close as possible to the base.

Secured on one end of base 6, directly above the water intake passage .10, is a rotortype pump P. At the opposite end of base 6 I provide a mounting place for a prime mover such as the gasoline motor indicated at M. It a gasoline power plant is used it is quite desirable that it be made up of a plurality of opposed cylinders 1:2. This makes possible to keep the overall height of my motor to a minimum and also tends to reduce vibration.

Base 6 is so proportioned that the center lines of pump P and motor M will coincide, permitting them to be direct connected as by the coupling 14:.

I provide that the gasoline tank T be mounted at a higher level than the carburetor 18, and directly over the motor, so that gravity feed may be employed. This mounting protects the water piping, spark plugs and other small parts from injury.

As carburetor 18 and its associated small parts and piping might be subjected to possible damage, I have provided a protector plate 20, which, as illustrated particularly in Figure 2, not only protects the carburetor but due to its secure anchorage at 22 to the base 6 provides a rest when it is desired to carry my pumpcr. This preferred arrangement serves .to protect these parts and re duces the number of outstanding projections which might catch on brush and the like.

To this end I prefer to give plate 20 an inward curve as indicated which will nicely fit the hips or shoulders of a man when he is carrying the device on his back[ I have found, for instance, that if a trump line be used to hold the pump end of my device against a man?s shoulders, and plate 20 be rested on his hips my device may be conveniently carried without the use of any special. carrying frame-work, which, when used, has the disadvantage of adding appreciably to the weight to be carried.

When a carrying frame is used to assist in transporting my device the motor end is usually carried uppermost and in this position the protector plate prevents the carburetor tip striking the carrier on the shoulders.

I prefer to use a water-cooled motor as water is, of course, always available whenever the pumper is used, and to this end. I 7

lead a line 24 from the pressure side of the pump P down into the base cavity where a Siamese coupling 26 is provided so that a separate water supplied pipe 28 may be sent to each cylinder. I have found it necessary to provide a valve 30 so as to control the pressure built up within the water jackets of cylinders 'ficient pressure might be applied to break the light cylinder jackets. This piping, as can be observed from Figures 1 and 3, is almost entirely enclosed within the cavity of base 6, the Siamese joint being adequately protected by the web-members 8 and 9.

The water intake 10 and the pressure gauge 30 are adequately protected by cross member 9, and the end of base 6. Cross member 8 gives additional security to the carburetor, the intake manifold and other associated smallparts. j

The foregoing description and the accom panying drawings clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely ilpower transmission mechanism between the pump and the engine, said base having a recess depressed below the level of the engine to accommodate the fly wheel of the engine, and a concave cross-plate, (forming a shield when the unit is packed on the back) secured at its opposite ends to and spanning a portion of the open bottom of the base.

In witness whereof, I hereunto subscribe my name this 2nd day of April, A. D. .1930.

EARL W. HIMBERGER.
