and gear wheel; said partsbeing a.portion of the device by which the pistons are operated.
Similar letters of reference denote like parts in the several figures.
My invention consists in giving by a peculiar means a variable motion to two pumppistons, so that their downward movement will be quicker than their upward movement; the two pump cylinders being connected by a water passage, and the pistons, which work in opposite directions, provided with valves; the whole being arranged as will be hereinafter described, whereby the pump will throw a continuous stream of water and one of equal volume at all points of the strokes of the pistons.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A., B, represent two pump-cylinders, between which a chamber C is placed; the cylinder A communicating with the upper end of said chamber by means of an opening (a) and the cylinder B communicating with its lower end by means of an opening The upper end of the cylinder B communicates with a force-pipe D, above the chamber C, as shown clearly in Fig. l.
E, is the suction pipe, which is attached to lower end of cylinder A; and F, G, are the pistons, fitted as usual intheir respective cylinders; each piston being provided with a valve (c) opening upward; see Fig. 1.
To the upper end of each piston rod H, a flat bar I is attached, and a strap J is attached to the upper end of each bar I; said straps passing over pulleys K, K, fitted in the upper part of a framing L; each strap having a weight M attached to it, which weights counterpoise the pistons.
In the framing L, two shafts N, O, are placed, one above the other; and on each shaft a toothed wheel P is placed; said wheels gearing into each other, and being permanently attached to their respective shafts.
On each of the shafts N, O, two pulleys are placed loosely; and the pulleys Q, Q, on the lower shaft N, are somewhat larger in diameter than the pulleys R, R, on the upper shaft O, as seen in Fig. 2.
To each of the bars I, two chains S, T, are attached at points (ci) (c) as shown in Fig.v 2; the chains S, being attached'to the larger pulleys Q, and the chains T, attached to the smaller. pulleysR.
Through each of the pulleys Q, Q, R, R, a bar (f) passes. The outer ends of these bars are attached to springs (g) which are secured to the outer sides of the pulleys.
To each side of each toothed wheel P, a ledge or projection is formed, and two beveled projections (i) (j) are formed on vertical bars U, U, which are attached to the framing L; one bar U being at each side of the framing, and two projections (i) (j) on each bar.
The operation is as follows: Power is applied to the upper shaft O, and a reciprocating motion is given each piston by the pulleys Q, R, which act through the medium of their chains S, T, alternately upon the bars I; the larger pulleys Q depressing and the smaller pulleys R elevating them. The pulleys are made to act alternately on the bars I, in consequence of being alternately connected with and disconnected from their respective shafts by means of the bars (f) which are -actuatedby the springs (g), attached to the pulleys, and the beveled projections (i) (j) which are attached to the bars U,'U; the bars (f) being thrown out free from the projections (it) on the sides of the wheels P, by the projections (i) (j) and forced inward so as to be acted upon by the projections (71,) by the springs (g).
The projections (7L) on one side of the wheels P are placed at opposite points from those on the other side, so that the two pistons F, G, will be operated or moved in opposite directions, that is, one moving upward as the other moves downward; and as both pistons move downward quicker than they move upward, it follows as a matter of course that there will not be any cessation of the upward or forcing power of the pistons; for instance the piston G (see Fig. l) is nearly at the upper end of its cylinder A, and the piston F of the cylinder B is fully depressed or has reached its lowest point, and before piston G reaches its culminating point, the piston F will ascend; consequently there will be at all times a forcing power. The direction of the water through the cylinders A, B, and chamber C, is indicated by the blue arrows. When piston G ascends, the water passes up through the suction pipe E into the suction end of the cylinder A, and the water previously drawn up into this cylinder is forced through opening (a), down through chamber C, through opening and up through valve (c) of the descending piston F, and out of pipe D. As the piston G descends, the piston F, in ascending, draws the water up through the valve of the descending piston G. Thus it will be seen that the pump will not only throw a continuous stream, but will throw a stream of equal volume.
I am aware that two pistons having a variable movement, and fitted within one cylinder, have been previously used; therefore I do not claim giving a variable Inovement to the pistons, irrespective of the arrangement herein shown. But
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is:
The peculiar means employed for operating the pistons or giving them the variable movement as described, viz., the pulleys Q, Q, R, R, connected with the bars I, of the pistons F, G, by means of the chains S, T; the pulleys Q, Q, R, R, being placed loosely on their shafts and connected alternately therewith by means of the bars (f), connected with the spring (g), the projections (L) on the wheels P, and the beveled projections (2') (j) on the bars U; the whole being arranged substantially as described.
