WALTER PECK, OF ROCKFORD, ILLINOIS.

PUMP.

Specification of Letters Patent No. 28,193, dated May 8, 1860.

.To all whom fit may concern:

Be it known that I, VALTER Prion, of Rockford, county of lVinnebago, in the State of Illinois, have invented certain new and useful Improvements in Pumps; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention consists in certain improvements of construction in double acting pumps, as hereinafter fullyT described.

To enable those skilled to make and use my improvements I will describe the mode in which I have practiced the same, referring by letters to the accompanying drawings forming part of this specification and in which- Figure l, represents a perspective view of one of my improved pumps. Fig. 2, represents a vertical section through the same. Fig. 3, represents a partial vertical section illustrative (to be explained hereinafter) and Fig. 4, represents detail perspective views of platform collars.

In the drawings the piston of the pump is illustrated as being coupled to the first section of the pipe. This illustration is theoretical, to admit of drawing on a larger scale than could be well adopted were the pump placed at the distance below the platform at which it would be in practice.

In the different figures the same letter indicates the same part of the apparatus.

A, represents the platform or floor which covers the well hole and which may be made of any desirable material. On this floor A is erected a cast iron stand, C, in the top of which is hung on a pivot the handle, B, by which the pump is operated.

a, is the hollow piston rod which is connected at its lower end to the piston, T, and has affixed to or formed on its upper end the cap F, which is furnished with a suitable spout D, and which is pivoted by a pin, o, to the short'end of the lever or handle B.

O, is a block which is permanently located at the bottom of the well and to which is secured a stand P, so constructed as to form a boX for and receive a ball joint z., formed on the lower side of the bottom piece, g, of the pump cylinder: this bottom piece, g, is formed with a series of conduits or induction passages, m, extending from its outer circumference to its center hole, or basin, n, (see Figs. 2 and l) and is constructed so as to fit (with a packing m) into and be securely fastened to the bottom of the pump cylinder E, and is furnished with a flap valve, Z.

The upper end of the pump cylinder is made with an enlargement, or rim of increased diameter as shown at t, (see Figs. 2 and l) which forms a shoulder on the internal surface of the cylinder. On this shoulder is placed the packing of the piston T, which packing is formed as follows viz:

r, is an annular collar which encircles the piston T, and fitting withinl the rim portion, t, of the cylinder rests on the shoulder, lw, (see Fig. 2). On this collar is placed a layer of fibrous packing material, p, (tinted blue at Fig. 2) and on top of this packing, p, is placed another (packing) ring, or collar, g, onto which latter collar (Q) the top cap S comes down.

The hollow piston, T, is considerably less in external diameter thanlthe internal diameter of the cylinder E, and said hollow piston, T, is formed with a head, I, which is of a sufficiently great diameter to fill the cylinder and is furnished with a suitable packing ring, z, to insure its tight working in said cylinder as illustrated at Fig. 2. In the bottom of the piston is located a iiap valve, lc', opening upward, as does also valve, Z, already referred to. It will be seen by reference to Fig. 2 that as the head, I, of the piston T, leaves the upper end of the cylinder E, an annular space G is created in said cylinder and surrounding the body of the piston T. A communication between this space, G, and the inside of the piston T, is formed by conduits, Y, in thehead I, of the piston (see Fig. 2.).

is a valve in the upper end of the piston and opening upward.

b is a slot cut in the floor A, equal in width to the diameter of the piston rod, a, and of suflicient length to admit of the throw or swing of said rod, a, the pivot, e, moving in the arc of a circle.

d, is a collar which is fitted loosely to the rod, a, and of suiiicientdiameter to cover the whole of the slot, I), and slides 0n top of the Hoor A while the rod, a, passes up and down through it.

e and 7 are two collars one with a slot and the other without. The advantage of these collars will be understood by the description of their operation which will be present-'ly given.

ball and socket joint as''he'reinfdescribedV the ulpper end of the pump rod may be vibrated in any desired direction (thatis the stand, c, may be arranged on any lside) Y and further that there will be no jump or jar to the pump it being held down perfectly tight and yet allowed to vibrate freely. 21j

am aware that in this kind `of-pump the cylinderA has been hungby a link joint to a weight or anchor: but such an arrangement does not accomplish the ends attained by my improvement. Y

The pumping operation of my improved apparatus is as followsn viz: Suppose the piston head, I, to have been elevated until nearly in contact with collar, lw, (by pulling down the hand end of lever 13,) when the water will have arisen by atmospheric pressure in the cylinder E, until up to bot'- tom of piston head, I, passing throughl the valve, Z,: then by causing the piston to descend the valve, Z, will be closed and the water contained "in the cylinder will` be forced to occupy the inside of piston, T,`

passing through valve le, and passing the conduits, y. The water will also fill round the piston in the annular space, G. Then on `causing the piston to ascend the body of water in it will close the valve, c, and all the water in the space, G, will be forced through the conduits, Y, into the piston, T, and up through valve, z'. Meanwhile the Vcylinder is filling up 'below the piston and ,is elevated at each upward and each downward stroke and also that the column of water is forced, out at the exit at each stroke of the piston with a velocity proportionate to the velocity of the stroke.

It will be seen that by the construction of the pump as hereinbefore described it is made double acting with simply a single cylinder, and piston, while the apparatus is simply and durably formed. The bottom piece, g, it will be observed is formed wit-h the ball, It, for the attachment and also with radiating and nearly horizontal conduits, or induction passages, m, leading to its center cavity, n, while on its top is arranged the valve, Z, and around its circumference an inserted packing ring, By the employment of a separate bottom attached to the cylinder the lower valve may be much more readily fit-ted to its seat than when arranged in a solid bottom to the cylinder and this separate bottom piece I make constitutes the ball oint also, while by formingsaid bottom A piece with Ithe annular packing, w, I render it "capable of'being more easily and per fectly ittednto the cylinder (by simply inserting' it andesecuring by bolts) and by forming therein the induction passages m.

'I am enabled to more economically make said passages than if made in the cylinder itself: 1-

In order to avoid the objections to this kind of pump which arise'foutof' the lateral'motion Vof the piston rod (or pipe) in the Hoor or lwell c'over, without the expense of' the Vnecessarymechanism of converting the vibratory motion of the handle into a vertical reciprocating motion to operate said piston rod, have arranged around the piston rod a collar, ,'which is so ittedas to admit of the moving of the said rod up and downy through it and is ofsufflcient iameter to extend over the slot, in iloorA at all .'mes during its sliding over the sur ace of the latter to keep said slot always covered and prevent the falling in of particles of dirt. At Fig. 3, is illustrated another method of protecting the slot, b, by means n'of two collars one (e) being formed with slot corresponding in size and shape to the slot in the platform, A, the other fitted to slide vertically onthe rod, a, and laterally on the top of thelower one (6,) and both made with convex tops. This peculiar arrangement of collars e and f, thus formed is exceedingly advantageous in freezing weather, when the water dripped or spilt on the floor A, would freeze the collar d (shown at Figs. l and 2) .tight to said floor and obstruct the ready operation of the apparatus. It will be seenthat by the employment of the two collars e and f arranged as shown, the surface on which Vthe moving collar slides is elevated to a level above that which would probably be reached by flooding the iioor A and also that both collars being convex any water thrown on them would run olf while the surface of contact between the collars is so small as not to afford an opportunity'for the formation of suficient ice to impede the operation of the pump?. The operation of the collars and pump is illustrated at Fig. 3, where the moving parts are shown in two different positions onev in black the other in red lines. V

The perfect packing of the hollow piston T, in the pump head is insured by a very simple and novel device consisting of two rings or annular collars g and 1', with a body of fibrous material between and the whole so arranged that by the screwing down of the cap s, the body of packing material p, (see Fig. 2) shall be forced out around its external circumference against theV pump cylinder and around its internalcircumference against the piston. It will be seen that by thus combining the body of packing material p, with two simple collars stamped y Letters Patent is- 1WALTER PECK.

of sheet metal by machinery and used as an article of manufacture) and the screw cap s, a simple and eective packing box is attained.

Having described the construction and operation of my improvements, what I claim as of my invention and desire to secure by 1. Coupling the lower end of the pump to a iXed stand P, or its equivalent, by means of a universal joint substantially as lereinbefore described for the purpose set Orth.
