Description

0f; east iron hollow 011 the under side over the outlet m 2 1s seen in Figs. 4: und 18, flat 011 top where it is screwed to the top plate of the chamber by screws passing through the apertures and stmight 011 the end against which the adjusta ble head is placed. This head is a rectdngular casing with an oblong mortise h? in its center to admit the screw bolt which attaches it to the encl partition P of the outlet m and over which screw bo1t it plays loosely so as to permit it to be forced by the water against the wheelthe water pressing against the aforesaid lip 03 Which. is oast 0n the end of the same next the wheel and brought to 21 f'eather edge at its outer extremity. The head also 111oves in grooves in the bottom 2111d top plate of the chamber.

During ehe operation just described one of the opposite pistons Will be forced out from its grooves in the wheel by the pressure of the fiuid against its larger end and simultaneously with said movement the para11e1 piston to that just above mentioned Will also be forced into i1:s groove in the wheel by a similarly constructed converging segment as the one above mentioned a1- ranged 011 the opposite side of the cylinder to that above describedthe water commenci11g to escape from the cylinder through 2111 opening m in the bottom plate just before the piston arrives at the segme1it 71 said opening or outlet m f01' the escape of the water being made 01: an oblong or other form in the bottom plate 01: the chamber be- 10W the segment Whioh is made concave 011 the under side.

The mortises D Fig. 2 in the rim of the wheel am made oblong of the size of the sevoral ends of the piston moving therein. The piston also moves in grooves in the top and bottom plates of the wheel and cylinder, said grooves for the piston being made on the surfaces of the plates next the inside of the cylinder. In Fig. 15 E represents the grooves in the top plates 01: tho wheel.

The bottom plate L of the vvheel is mad0 of greater diameter than the wheel for the purpose of forming the bottom of the cylinder Whi0h it so forms 2113 Z Fig. 2.

- The top p1ate O c 0f the Wheel is made in like mnner with the bottom plate L Z and forms the top of the cylinc1er, the joints of the plates being rendered tight by su'1table packing and the under side being grooved as before stated in which grooves the pistons slide. See E Fig. 15. The sides 211101 ends of the pistons require no paoking being pressed tight by the water. The other joi'nts may be packed in the usual manner. The pistons may beincreased in number at pleasure.

Suitable gates G may be adapted to the outlets m .Eor shutting in and let-ting off the wafoer which gates are made of the form and siz e of the out1ets m in which they are placed having a orank shaft H passing through the center of the said gates with their ext-remities turning 111 suitable boxes in the foundat-ion F. In Fig. 14 these gutes a1e represented as shut. \Vhen they are open the edge on1y would be seen in this view.

The ou'tlets m 211e partitioned :Er0m the chamber by suitable partitions P made the dept-h of the ohamber the said artition having threo sides, the fourth side next the cylincler being open. See Figs. 2 211101 16.

The bottom und top of the chamber eure composed of circular rims o1 plates a secured to the upper and lower edges of the concentric rings (Z s forming the chamber; 01' said plates may be cast wit-h them 211101 perforated f0r the admission and discharge of the water by the perforations m q. This engine may 100 worked. by steam as W011 as water und in a vertical o1 horizontal posimon.

When used as a hydraulic engine the water is admitted through a tube inserted into the aperture g in t-he top plate of the charmber. When used as 21 sceam engine it must be provicled with the usual steam chest, valves and tubes for letting 011 and shutting ofi the steam.

In describing the operation of the engine t-he fiuid is said to press upon the large end of the piston forcing the smaller end 01113 against t-he chamber 011 the opposite side but the description may not state Wih sufiicient clearness how the pressure is removed from this large 011d of the piston at the time the piston is made 130 recede by the action of ehe 021111 2- WVe shall therefore give a further description of the operation of the pistons.

From the foregoing description it Will be seen that the pistonsare 'arranged in pairs, at right angles having their larg-e and small ends alternately 11ext eaoh other, the operation being conjoint-that is to say when oho small end. of one pair of pistons say 7a in Fig. 2 approaches near the outlet m and is ab the place marked w the sma1l end of the nearest piston j of the next pair j j when it arrives at the place marked Y is pushed out by the pressure 01 the fluid againstits larger end When at the place marked Zre'ceiving the pressufe 01": the head 013 water against its flat sides next the in1et n at the same time next piston in advance into its groove -amd the esca.pe or discharge of the water follow ing it.

/Vhat we claim as 0111 invention and which we desire 130 secure by Letters Patent is l. The construction and arrangement of the pistons-that is to say with large and smal1 ends as described and for the purpose sei: forth and crossing at right angles.

2. The method of moving the'pistons out from the wheel and across the cy1inder by the pressure of the water or steam uponthe larger ends and the closing 01' rendering the joints tight by the pressure of the fluid as described.

3. The movable se1f adjuscable heads h in combination with the converging segments 0r cams z against Which they are placed and move as described.

4:. The mode of. constructing the circular chamber in combination with a revolving wheel .and cylinder as before described-viz. in making the chamber with an inlet in its t0p for the admission 015 the water, openings in its side for the passage of the water 130 the interior of the cylinder and partitioned outlets in the bottom of sa.ic1 chamber for the discharge 0f the water.
