'A FFICE.
PATE-NT WILLIAM F. ROBINSON, OF BELLAIRE, OHIO.
IMPROVEMENT IN PUMPS.
Specication forming part of Letters Patent No. 117,463, dated July 25, 1871.
To all whom it may concern:
Be it known that I, WILLIAM F. ROBINSON, of Bellaire, in the county of Belmont and State of Ohio, have invented a certain Improvement in Prunps; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the annexed drawing making a part of this specification, in which- Figure I is an elevation of my improved pump, showing the barrel, the discharge-aperture, the handle, and the plunger or valve-rods. Fig. 2 is a vertical centralsection, showing the construction and arrangement of the parts.
Corresponding letters refer to corresponding parts in both iigures.
t This invention relates to that class of pumps which is usually denominated suction and lift-pumps and it consists in the combination and arrangement of some of the parts of which it is composed, as will be more fully explained hereinafter.
In constructing pumps of this character I use a tube or cylinder, which may be made of wood properly hooped 0r banded, or it may be made of any suitable kind of metal; and in either case it is to be of equal diameter throughout its entire length7 and be bored smooth upon its interior surface.
Upon the upper end of the barrel A there is placed a band, A, which has two arms projecting upward from it, they being bent inward so as to form the fulcrum for the operating-lever or handle. A similar band, A2, may be placed upon the lower end of the barrel; but it need not have the projecting arms. The operatinglever or handle has its fulcrum in the arms of band A1, and one of its ends being extended far enough to cause it to serve as a lever for operating the buckets or plungers, while its opposite end is only long enough to admit of the plunger-rod being attached to it. The rods which operate the plungers are of the bent form shown in the drawing, the one O being attached to the handle nearest to that portion thereof to which the force for moving it is applied, while the one C1 is attached to the other end at an equal distance from the fulcrum. The rod G extends downward to and is connected with the plunger D. The rod Ol also extends downward from the handle into the barrel of the pump, but only for a short distance, where it is attached to a cross-head, as shown in Fig. 2. This cross-head serves as a guide for the rod O which passes through it, and it also serves to communicate motion to two rods, O2 O2, whose upper ends are securedV to it,and which extend downwa'rd, passing through the upper bucket or plunger, and are secured to the lower plunger. There are two plungers or buckets, the upper one D being attached to the rod Cl by means of a bail, which serves as a cage for the valve D', which has its seat in the upper surface of said plunger. This plunger may be made of wood, or of metal, or of any other suitable substance, it being provided with grooves or other receptacles for packing, which, for water which holds in suspension much earthy matter, should be made of leather, or rubber, or some other elastic substance, but which, when the pump is to be used in pure or clear water, may be of metal. The lower bucketV or phmger is constructed like the one above described, it being' connected with the handle of the pump by means of the rods C2 O2, cross-head, and rod C1, the rods and a bail which passes over Vits valve serving as a cage for such valve to work in.
The operation of this pump is as follows: The parts having been constructed and arranged substantially as described, it is to be placed in a proper position with reference to the water to be raised, and securely held in such position, when, by pressing the long end of' the lever or handle down into the position shown in full lines in Fig. 2, the lower end of the stock or barrel being below ithe level of the surface ofthe water, it will flow up through the bucket E, the valve E rising to allow it to pass. The plunger or bucket D having been raised by the same operation, the space between the two buckets will have been considerably increasedand iilled or partially filled with water, so that, as the lever or handle is changed into the position shown in dotted lines, the valve E will have been returned to its seat, and the one D in the upper plunger will have been raised in consequence of the fact that the pistons will approach toward each other, thus contracting the space between them, and causing a pressure upon th e water which is-between them sufficient to raise the valve and carry the water above the upper plunger; and, as the operation above described is repeated, the stock or barrel is filled with water, and it will iioW out through a spout or pipe placed near its eaoh side of the fulerum, all substantially as and upper end for that purpose. for the purpose set forth.
