Show !W00D HYDRAULIC RAM ! One Been on Duty Fifteen Months Without Stop. Farmer Who Has Never Taken Course In Hydraulics Describes Pump He Made Himself Illustrations Show Make-Up. Some think that it takes a man who has had a course in hydraulics to put a hydraulic ram ln operation, but I think that is a mistaken idea. I have never taken a course and have seen but one ram besides my own at work, yet I have a ram which has been on duty about fifteen months, day and night, Sundays not excepted. Further than this, it was made out of wood, and on my own place. This is the , rial ::.-!. J.-l L 3fl'JZ753 way it was made, writes C. M. Gravely In the Farm and Fireside. I took a block of hard wood 10 by 12 by 30 Inches. A 1-inch hole was bored -from A to O, then from S to O, connected to A O at an angle. I mortised mor-tised from M to A O a hole 4 inches at the top as shown at V. A saucer-shaped hole was cut out at S as shown In sketch. A lever (Fig. 2) was made and pivoted at B. In a plate of iron 3-16 inch thick a hole was cut (Fig. 4). This was bolted down at M, using common bolts. A piece of sole-leather was placed under It to answer for packing and also to deaden the stroke of the valve. A hole was cut in -the leather the size of the hole in the plate. Fig. 3 was suspended in mortise V (Fig. 1). Into a plate of iron (Fig. 6) eighth -inch holes were drilled in a small circle. This was bolted down with lag screws over mortise at S. The leather valve (Fig. 6) was fastened fast-ened over holes (Fig. 6) with a small bolt through center hole in plate and in valve, and fitted water-tight at the bolt. Packing was placed under the plate and all screwed down tight. At X a cut was made of sufficient depth and width to allow an air-tube to be Inserted in a hole bored with a bit at a slight angle upward. This air-tube i t"u4' jr-r;i- I 7w 'o rit.3 L, Ji ( ) flG.4 ri&.5 was made of a Bmall piece of pipe, plugged at one end with lead, with a very small hole placed ln the plugging. At S was cut a circular groove to receive re-ceive the air-chamber, which was an old stove-pot. (The pot was not exactly ex-actly what I wanted, but was the best thing I had.) A strip of packing was put in the groove and the pot placed and bolted down. The timbers at 3 3 wei'e placed at right angles to the body of the ram, the top one being hol!owed out to fit the inverted pot. "The pot was fastened down with four long bolts that went through the timbers above and below. A -inch bore was bored downward and outward out-ward as shown at C C and R R, being be-ing connected at L L. The piping was well threaded and screwed directly into the holes in the timber to sufficient suffi-cient depth to insure a good hold. After all these things were done the ram worked successfully. In this particular case water enters the ram through A from a dam 10 feet higher than the position of the ram. The brace D prevents the valve from lowering too far. R comes from a spring which likewise supplies water to S. A check valve prevents the water wa-ter from being forced back into the Bprlng. The delivery pipe R, which leads to the house GOO feet away, is made of -inch pipe. |
