HYDRAULIC RAM;

Application filed January 8, 1926, Serial No.1 80,092. Renewed, June 20, 1927.

This invention relates to improvements in hydraulic rams, the general object of the invention being to provide me'ans'for making the ram adjustable for use with varying water volumes so that the ram can be used in situations where the water supply varies from time to time throughout. the seasons.

Another object of the invention is to provide anadjustable spring for holding the waste valve off its seat. Another object of theinvention is to provide means for. renewing the air supply in the air chamber of the ram. 7

Another object of the invention isto provide a storage tank for furnishing water to the ram which is float controlled and into which the water from thesupply pipe discharges. I I I V This invention also consists incertain other features of, construction and in the combination andfarrangement of the severalparts, to, be hereinafter fully described, illustrated in the accompanying drawings and specifically pointedout in the appended claims.

/ In describing my inventionin detail, reference will be had "tofthe accompanying drawings whereinlike characters denote like or corresponding parts throughout the severalviews, and in whichi v D Figure 1 is a view showing the invention in use.

Figure 3 is a top plan-view of Figure 2.

waste valve and its associated parts.

Figure '5 is a section on line 55 of Figure 2. p Figure dis a section on line 66 of Figure 2.

In these views, 1 indicates the housing of the waste valve of the ram which is formed with the discharge 2 and which hasa yoke frame 3 attached to its upper end. My improved waste valve comprises the main part 4 and the part 5 which fits in the recessed under portion of the part 4 and is rotatably mounted therein. .This part 4 is provided with a number of groups of holes 6, while the part 5 is provided with a number of slots 7, a slot being provided for each group of ho1es,'and these holes and slotes are so arranged that by moving the parts 4 and 5 relativeto each other, the holes 6 can be covered or uncovered by the solid portions of the member 5 and thus the discharge of Figure 4 is a bottom plan view of thewater through the waste valve can be regulated. A hollow stem 8 isattached tothe member 4 and is guided through a hole in the top of the casing 1. A solid stem 9is connected with the part 5 and passesthrough the stem 8 and has its projecting upper end a threaded to receive the nuts 10 which hold the parts of the valve together. Packing 11 may be placed between the parts 4 and 5.

A pin 12 is fastened to the stem 9 and v extends through a slot in the stem 8 so that f the stem 9 and its valve part can be partly rotated to adjust the valve part 5 in relation to the part 4. A collar 13 is held on the stem 8 by the nuts 10 and this collar has a Thusjby adjusting the nut 18, the shaft 17 is moved to adj ust the tension of the spring "15. This's pring tends to hold the valve in its" lowest position, and by properly adjusting the spring, the waste valve can be set to operate under the head of water in the ram pipe and thus eliminate the manual manipe ulation of the valve now necessary in starting up a ram.

7 From the foregoing, it will be seen that by adjusting the parts 4 and 5 of the waste valve relative to each other, the flow of water through the valve can be adjusted so that the ram can be used with water supplies of different volumes, and with a supplywhere the volume varies from time to time. With the small number of openings in the valve, the water would hold the valve against its seat 1 and thus prevent operation of the ram and in order to prevent this, I provide the-spring which forces the valve ofl' its seat again as this spring is adjusted so that it will permit the valve to close under the pressure of the water but ,will open it again when the volume of water loses its mo-. 'inentum, so that the water will again pass through the valve until its momentum closes the valve again. Thespring also eliminates the manual manipulation of the waste valve now necessary in starting up a ram.

I 1 also providemeansfor renewing the air in the airchamber 19' or the ram. Such means comprises a cook 20 at the lower end of the chamher and a cock Zl in the top thereof. lvhen the air supply is to he renewed, the valv 22 in the lift .pipe 21) is c'osed and the 'alves 20 and 21 are opened. ater in the air chamber will escape through the valve 520 and air will flow in the chambelu to take the place of the Water, through the valve 31. When enough air has entered the cocks are closed and thus the air aviil he trapped in the chamber. A valve 29 in the supply line is closed when the air *alves are open.

I also provide a storaee tank 2t tor holding' a supply of Water tor the ram so that the ram can he continued in operation over a dr spell. The Water is deivelted to this tank from the source of supply through the pipe 25 and its outlet to the ram pipe 26 is controlled by a 'alve 2T. the stem 28 of which is connected to the float rod 29 so that as soon as the tank is full. the valve will he opened by the float so that the water from the tank will pass to the uni. \Vith this tanln the ra 111 can still he used Where the supply has dwindled to such a small stream that it would not he sutlieient to operate the ram itit passed to the am direct.

This tank can he used with nrv improved form of waste valve. as said valve is automatic in operation so that as soon as the water is released from the storage tank hy the operation of the valve in the Heat. the ram will start to work without manual manipulation of the valve. Otherwise the parts. provided that sneh changes all With in the scope of the appended claims.

What ll claim is:

1. In a Faun a waste valve, adjustable spring means for holding the same oil its seat and adjustable 1110411 11.; for regulating the r amount o1: water passing; through the valve.

In a rain, a waste valve composed of two parts each having ports therein a hol- 'on stem connected with the upper part, a stem connected with the lower part and pass inn through the hollow stem, means connected with one stem for moving it in relati n to the other stem and a scale on the other stem to! indicating the amount of movement of: the first tom.
