J. STEVER, OF BRISTOL, CONNECTICUT.

ARRANGEMENT OF MEANS IN PENDULUlVI-PUMPS FOR SHIPS.

Specification of Letters Patent No. 15,395, dated July 22, 1856.

To all whom t may concern Be it known that I, J. STEVER, of Bristol, in the county of Hartford and State of Connecticut, have invented a new and Improved Mode of Operating Ships Pumps; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to t-he annexed drawings, making a part of this specification, in which- Figures 1 and 2 are side views of my improvement.

Similar letters of reference indicate corresponding parts in the two figures.

My invention consists in attaching a series' of pumps to a frame which is secured to a hollow vertical shaft which is allowed to turn freely in its bearings, the pumps communicating with t-he hollow shaft and having weights or bobs connected by gearing and levers with their pistons so that the pumps will be operated by the motion of the ship or vessel, the hollow shaft serving as the force and suction pipe as will be presently shown and described.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a vertical hollow shaft which is secured within the hold of a ship or vessel. This shaft is allowed to turn in its bearings and has a frame B, attached to it. The frame B, is formed of two horizontal plates (a), (ce), through the centers of which the shaft A, passes, the plates being secured to the shaft and connected by strips or uprights (o), (b), one at each side of the plates.

To the lower plate (a), there are attached pumps, C, four are shown in the drawings, one at each corner, but more or less may be used. The lower ends of the cylinders of these pumps are connected with the hollow shaft A, by pipes D.

The lower end of the hollow shaft A is perforated and the upper end is fitted within the end of a horizontalpipe (c) which forms the upper bearing of the shaft.

E, represents the plungers of the pumps and F, the plunger rods. The plunger rods of the two pumps at each side of the lower plate (a), are connected with the ends of levers G, and the center of the levers G, are connected by pivots (al), with the strips or uprights (b), To the center of each lever Gr, there is attached a geared sector H. These sectors H, gear into sectors I, which are attached to the upper ends of vertical bars J, secured by pivots (c), to the strips or uprights (b), the bars J being hung loosely on the pivots (c). yTo the lower ends of the bars J, weights K, are attached, one to each.

The lower ends of the cylinders of the pumps, C, communicate with the shaft A, by pipes L, the shaft A, having a partition (f) within it directly underneath the pipes L, so that the upper part of the shaft A, is a discharge o-r force pipe, and the lower part below the partition a suction pipe. The lower part of each cylinder has a valve in it directly over its pipe D.

The operation of the pumps will be readily understood. The frame B, and shaft A, will move or be inclined of course corresponding to the movement or inclinations of the ship or vessel and the sectors I, will be moved by the swing of the weights K, and the levers, Gr, and the plungers E, will be operated the bilge water being drawn up through the lower end of the shaft A, into the pipes D, as the plungers rise and forced through the pipes L, into the shaft A, above the partition (f) and out of the end of the pipe And as the shaft A, turns in its bearings as previously stated it will be seen that the shaft A and frame B, `will turn and consequently the direction of the movement or swing of the weights K, will always be in the same plane with the movement of the ship or vessel, so that the pumps will be operated whether the ship is rolling from side to side or pitching fore and aft. Air pumps may be operated in the same manner and at the same time by attaching them to the frame B, and having suitable pipes connected to them so that a ship or vessel may be ventilated by the same device. y

Having thus dcribed my invention what I claim as new and desire to secure by Letters Patent is- Attaching a series of pumps, C, to a hollow shaft A, which is allowed to turnv J. STEVER.
