HYDRAULIC ENGINE.

,Specification of Letterslatent No. 10,665, dated AMarch 21, 1854;.-

To all whom t may concern.'

Be it known that we, AUGUSTUS @CARE-Y and JEREMIAH SMITH, of Ipswich, inthe county of Essex and State of Massachusetts, have invented a new and improved Hydraulic Engine; and we `do hereby ,declare that the following iis a full, clear, vand exact description of the construction and opera-v tion ot the same, reference being had to the annexed drawings, making aipart of this specication, in whichf Figure l, is a side elevation of an improved hydraulic engine. Fig. 2, gis ra plan or top view of ditto, the tops of the trunks in which the pistons work, being removed.

Similar-letters of reference indicate corresponding parts in the two gures.

This invention relates to a new and improved hydraulic engine, whereby the ,power of water is applied to the propelling of machinery, and is' intended to be .used 'in lieu of the dilerent water wheels in present use.

The nature of our invention consists in having two horizontal trunks, wate-r chambers, or cylinders, provided each with a valve and piston. The pistons have adjust# able or movable heads, and the ends `ofthe piston rods are secured to connecting rods or levers, which are attached to reverse cranks on a shaft, having a gear wheel upon it, from which gear wheelV the power is taken. The water from the'flume is made to act, by means of the valves in the trunks, chambers, or cylinders, first against one piston, and then against the other, and a continuous rotary motion is given the crank shaft The water in the trunks, chambers, or cylinders, after acting against the pistons the length of the stroke, is let out by the operation ot the movable heads, as will be hereafter fully shown and described.

The arrangement of the valves and movable piston heads, constitute the finvention.`

To enable others skilled in the art, to make and use our invention, we will proceed to describe its construction and operation.

A, A', represent two trunks, water chambers, or cylinders; rectangular A trunks are shown in t-he drawings, but cylinders may be used. These trunks are placed in a horizontal position, and parallel with each other, as shown in Fig. 2. The outer ends of the trunks are provided with flanges, and are secured directly to the flume, or to pipes, B, B, leading therefrom-#see dotted lines. "Within the trunks, A, A, and near their outer .endsfare valves,C, C, one in each trufnk. These valves are'hung :upon :hori- Zontalshatts, (a), (a), whichy pass directly through their centers, and have their-bean ings in fthe sides of kthe trunks, `see Fig. .2..

D, D', are the piston heads which are (b), (b), to which the vpiston rods, E, E, are secured by joints, (0),;(0). The lower ends :of the heads, D, D', are attached by pivots, (al), (di), to rods, F, F, whichpass through eyes, (e), (e), underneath the pis- :ton rods,A see Fig.' l, and the outer ends ot the rods, F., are bent or curved at right angles with ytheir other parts,1as shown at ff, ffinFig. 2; y

G, G, are .two `vertical pins or studs, .placed at a distance apart, equal .to the length kof the stroke lof the piston. YThereare twopins :to `eachitinnk,and the pins are Lplaced at the inner ends of the trunks, and in line with the bent portions, (f), (f), ot the rods, F, F,

asshown 1n Fig. 2.

vThe outer vends of the pisto-n rods, E, E, are connected by pivots, (g), `(g), tothe lower ends ot levers,H, H, which have their fulcra at (7L), .(L), and the upper ends of the levers, H, H, are connected by pivots (z'), (i), to connecting rods, I, I, which are Curved 2111115 (i), (j), (3"), (LDFW t0.

each pin, and an arm on each side of the shaft,vK; the lower ends of each pair of arms are secured to a bar, (k), which works upon a center', To each end'of the bars, (1), a wire, (m), is secured, and these wires are attached to arms, one one end of the valve shafts, (a), (a).

M, is a gear wheel upon the shaft, K,"from which gear wheel the power to be applied to the propelling of machinery is taken.

Operation: The water passes simultaneously into bot-h trunks, A, A, and is arrested in one ot them bythe closed valve, C. The valve, C', in the other trunk, A, being open, the water acts upon the piston head,

D, and forces it along till it reaches the endv of. the trunk, when the valve, C, is closed, by means of thepin, L, acting againstthe N iran sTArns PATENT orrion.

.y constructed similarly to the valves, C, C, i -theheads being secured at the ends `of boxes,

Contact with the outer pin, G, and the water passes out ofthe trunk. A short time previous to the closing of the valve, C', the valve, C, in the opposite trunk, A, is opened by the pin, L, acting against the arms, (j) (j), and the water acts against the head, D, a short time before the head, D, in the opposite trunk, stops. The head, D, is now forced along, and the head, D, is consequently moved back, in an openstate, to its original position in the trunk, A, owing to the connection of the piston rods, to the crank shaft, K, when the head, D', has nearly reached the length of its backward stroke, the bent portion, (f), comes in contact with the inner pin, G, and closes the head, D, which is now ready to be again acted upon by the water. Y

The heads and valves in both trunks are constructed and act precisely similar, but alternately, and a continuous rotary motion is gven'the shaft, K.

lVe have experimented with the within described machine, and find that we obtain more power under a given head of water than can be obtainedby the ordinary water wheels. We apply the water to the lowest point of the fall.

lVe are aware that hydraulic engines have been previously used, but differently,` constroke.

structed from ours. vWe do not claim pistons attached to a crank shaft and working, by the force of the water, alternately in trunks or cylinders, `for the purpose of applying water power to the propelling of machinery. But

What we claim as new, and desire to secure by Letters Patent, is

The peculiar arrangement of the valves, C, C', and piston heads, D, D, as herein shown and described, viz: the piston heads being movable, or hung upon centers, and

opened andclosed by means of rods, F, F,

acted upon by pins or studs, G, G, at each end of the strokes of the pistons, the valves, C, C, being opened and closed alternately,

by means of the pins, L, L', on the crank shaft, K, acting against the arms, (j), (j), (j), (j), by which arrangement the water is permitted to act not only alternately upon the pistons, but also allowed` to escape from the trunks or cylinders when the water has forced them along within the trunks or cylinders, the required distance or lengthl of AUGUSTUS C. CAREY. JEREMIAH'SMITH.
