AOur invention has for its object to furnish `an improved pump and Iireengine which shall be simple in construction, convenient in use, effective in operation, and at the same time inexpensive in manufacture; and it consists in the construction and combination of the various parts ofthe machine, as hereinafter more fully described.
.A represents a low frame, to which the operating parts are attached, and which is designed to support the said parts above the bottom of the well or cistern in which the machine is placed. B is an immovable circular chamber, which is attached to and supported by the frame-work, and with an opening, b1in the upper side of which is connected the lower end of the discharge-pipe C. In the bottom of the immovable circular chamber B, at suitable distances apart, are formed a series of openings, b2, which are provided with drop or other suitable Valves, D, opening upward. E
`is a series of pump barrels or cylinders, which are" arranged radially, and the outer ends of which are connected with the immovable circular chamber B, and their interiors communicatey with y the interior of the chamber B through the openings b2 and valves D. The
. inner ends of the barrels or cylinders E are open` to allow the water to flow in freely. F are the pivoted pistons or plungers, which are constructed in the ordinary manner, and are provided with valves f' opening inward, so that, as the pistons F are drawn outward, the pressure of. the water may open the valves f' and allow the water to iiow in and ll the cylor hinged the ends of the piston rods G, the l other ends of which are pivoted to the ring Y H whichA passes around the eccentric I J K. One or more of the pistonrods G may be rig-` idly attached to the ring H to prevent the said ring from turning so much that the pisy tons F or rods G may bind. The inner sur.l
face of the ringH is made smooth so that the rollers J of the eccentric I J K may roll along it smoothly. The rollers J are pivoted in a circle to and between the circular plates I K in such vpositions that their faces may come in contact with and roll along the face of the ring H. The circular4 plates I K are attached eccentrically to the lower part of the shaft L7 the lower end of which revolves in a step formed in or attached to the base-frame A, and to the upper end of which is attached a lever or sweep for operating the machine.
The eccentric I J K maybe kept in the ring H by making the lower plate I a little larger than the opening through said ring H, so that` its edges may overlap the under side of said ring H, and by attaching projections M to the upper plate K, to overlap the top of the said ring H, or in any other convenient manner.`
Having thus described `our invention, `we
claim as new and desire to secure by ,Letters Patent- The fire-engine pump herein described, con`` structed with an immovable circular chamber B, discharge-pipe C, radial pump-barrels E,`
rigidly attached, the valves D, together `with the valved and. pivotedpistons-F operated? by a ring, H, and a cam on the driving-shaft,`
as and for the purpose specified.
