'UNITED sTATEs PATENT onirica.
WILLIAM SHEARER, OF ATLANTA, GEORGIA.
PUMP.
Specification of Letters Patent No. 29,723, dated August 21, 1860.
To aZZ 'whom "Zt may concern:
Be it known that I, WILLIAM SHEARER, of Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Improvement in Force and Lift Pumps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in which- Figure l, represents a side view of my improved pump. Fig. 2, represents a section through the center of the pump, the section cutting the center of t-he handle and spout, but not the piston rod H.
In the drawings A, represents the base of the pump, having a water chamber B, as shown in section, Fig. 2, a, being the inlet, and b, c, the out-let valves which lead into the central part of the pump D, the latter being provided with a large central chamber B and two side passages e, (Z, the passage CZ, communicating with the lower part of chamber B, at g, and with the discharge chamber F, at f, while the passage e, communicates with the chamber B, at c, and with the upper part of the chamber B, at g.
G is the spout or discharge tube.
H, is the piston rod having a screw thread cut on each end and being enlarged at I, so as to permit of the screw journal J, passing through it. Upon each end of the piston rod H, is a piston or head z', packing j, packing plate 7c, and packing nut Z, the latter belng provided with holes I, I, into which a lever can be inserted to turn the nuts Z, Z, to tighten up the packing y'.
K is the .handle pivoted to a projecting piece on the side of D, at N, so that its forks L, L, pass on each side of the pump and are connected to the screw journal J, by means of link pieces M, one on each side of the pump.
The openings ZJ, c, f, and L, are to be provided with suitable valves, which in this instance, are formed out of the leather packing pieces 3, 8, the weights 2, 2, 2, 2, being em ployed to keep them down. Any other suitable construction of valves can be employed.
The operation is as follows: As the handle K, is worked down it causes the piston rod H, and pistons z', to move up to the top of the chamber B, as shown in Fig. 2, whereby the water is drawn up from the chamber B, through the valve Z), which opens upward. Vhen the handle K, is raised the water in the bottom of the chamber B', causes the valve b, to close, and being thus prevented from escaping back into the chamber B, it is forced through the opening` g, up the passage cZ, and through the valve f, into chamber F, from which it escapes or is discharged through pipe or spout G, while the valve c, opens and permits the water from chamber B, to pass up the passage e, and through the opening g', into the upper part of the chamber B', as fast as the piston rod H, and pistons z', z', descend. Now it will be seen that on the next downward motion of the handle K, that the water in the upper part of the chamber B', will be forced up through the valve L, which opens upward, while the valve c, will be closed, and the valve b, again open. A constant llow of water from the pipe Gr, will thus be kept up, although the stroke of the piston rod H is very limited. The center of D, is cut out as seen at O, to permit of the play of screw journal J, and also to permit of the nut plates I, being turned to tighten up the packings j, y', Without detaching any part of the pump. This is a great advantage, since if one packing happens to get a little loose, it can be tightened up by one turn of its nut plate I, whereby the packing plate 7c, which is so constructed as to slide freely over the thread on the piston rod H, is caused to press upon the packing j.
My pump can be manufactured very cheap, is simple, and can be used under water or above water, as may be desired; and also as a lift and force pump or either.
The parts A, D, and E, are held together by bolts or screws, 4, 4, 4:, as shown in. the drawings.
By simply taking off the bottom A, and unscrewing the journal J, the piston rod H, together with the parts connected therewith, can be slid out of the chamber B. Again, when desired, the journal J, can be unscrewed so as to be withdrawn, and then the piston rod H, turned half-way around so as to cause the piston heads to wear even and true.
and Water passages ZZ, e, arranged to operate 1o in relation to each other as'and for the purposes set forth.
In Witness whereof I have hereunto signed my neme.
WILLIAM SHEARER. wWitnesses W. R. JACKSON, T. L. THoMAs.
