GEORGE STEGK AND FRANKLIN ARNOLD, OF HUGHESVILLE, PENNSYLVANIA IMPROVEMENT EN PUMPS.

Specification forming part of Letters Patent No. 121,016, dated November 14, 1871.

To all whom it may concern:

Be it known that we, GEORGE Srncx and FRANKLIN ARNOLD, both of Hughesville, in Lycoming county and State of Pennsylvania, have invented an Improved Pump; and We do hereby declare the following to be a full, clear, and exact description of the same,reference being. had to the accompanying drawing forming part of this specification, in which- Figure l is a vertical section; Fig. 2, a side elevation, showing the upper part of the apparatus Fig. 3, a section, showing-the method of connecting the racks and plunger-rods; Fig. 4, a side view of the box, with a portion of the wall broken away to reveal the internal construction; Fig. 5, a horizontal section of the box in line 00 m of Fig. 4; and Fig. 6 is a section in line 3 3 of Fig. 2.

Similar letters of reference in the accompanying.

drawing indicate corresponding parts.

Our invention,- although in many respects adapted to all classes of hand-pumps, relates particularly to that classin which the water is raised by atmospheric pressure, and the main principles of the invention are applicable either to rais-. ing water from shallow wells or from deep ones, where it has to be elevated from one point to another by successive relays or stages. The invention consists, first, in a pump-box and valve of novel construction; second, in a new arrangement of the parts for working the plunger uniformly in a perfectly vertical line and so as to economize power; and thirdly, in the general combination of parts constructed as herein set forth.

In the drawing, B indicates the box, which may be either round or square, according to the form of the pump-barrel. Whether round or square, it is constructed or cast with two side pieces, I) I), connected at their upper ends by a d1ametrical cross-bar, I), which receives the plungerrod P, and also serves to support the valves V V, the two sides b I) being separated by a space, 0 0, where their edges approach each other, and by a wider space inside of the points 0 0, so that the water can pass freely up on both sides of the cross-piece I), from said cross-piece to the wall of the pump. At the same time provision is thus made for the proper support of the valves,

both at their hinges and around their edges, at every point except the space 0 0. The upper surface of the cross-bar b is on a level with the upper edge of the walls I) I) at the openings 0 0; but between those points the metal is cut away, as shown along the lines 0 6, so as to partially countersink the valves, and at the same time cause them to sit in an inclined position, whereby they lift easily when the box is descending, and also wedge closely down against the wall of the pump and form a water-tight joint when the box is ascending. The valve consists of two pieces, 21 o, of wood or metal, (nearly semicircular in round pumps,) which fit closely down upon the box, as shown in Fig. 4, and are supported by a nearly circular piece, 0, of leather, rubber, or other equivalent flexible material, riveted or clamped by a bar, n, upon the cross-piece b. The edges of this leather strip are cut so as to flare outward from their lower to their upper surface, as

shown in Fig. 4. The clamping-bar or plate it may be fastened down upon the leather by rivets, or by a screw-nut or collar around the plunger-rod, as shown at i, or in any other suitable manner. The construction of box and valve here shown and described dispense with all superfluous weight of material, yet renders the box steady in its movement, enables the water to act with full leverage in raising the valves, and yet allows the valves when the box is rising to spread against the wall of the pump, forming a tight joint, as above described. The whole can be readily constructed, and when necessary to repair the valves in any way they can be readily taken out and readjusted, or new ones substituted, by anybody, however inexperienced in such matters. The box and valve thus constructed are to be used in the ordinary way in short single-barrel pumps where the draught is less than thirty-three feet; but where, it is over that distance we connect a pump-stock, G, some thirty feet in length, to a vessel, A, which is divided into two compartments by a partition, to,

extending nearly to its top. We pump the water up into one compartment, letting it run over into the other, which is open to the air. We set another pump stock, G, in this compartment, which lifts the water therefrom thirty feet more and pours it into another vessel similar to that at A, from which it is again raised another stage, and so on to any required height.

The means which we employ for operating the plunger-rods or series of plunger-rods connected with the difi'erent stages are as follows: We attach a couple of guide-standards, F F, to the pump-cover or frame, and connect them by crossbars H provided with journal-boxes h at their center. In the guides we place vertical racks It R having lateral flanges r 1', which hold them true to a vertical line. The two racks are constructed with an enlarged lower end, 7", having a recess in the rear side and a straight hole directly through from the recess to their front side, as shown in Fig. 3. The upper ends of the plunger-rods are bent to a right angle or a hook, as there shown, and inserted from the rear side of the racks, so that, when the latter are lowered into the guides after being thus connected, the guideflanges r 0" keep the racks in place, and the top of the plunger-rod being confined between the wall of the guide-groove and the rear side of the racks, cannot become detached nor work loose, although they are not bolted nor otherwise fastened to the racks. To detach the parts, it is only necessary to lift the racks high enough to bring the shoulders of the plunger-rods above the guide-standards, when they come apart without diificulty. The racks, which thus rise and fall in a perfectly vertical line so as to wear the pump-boxes vertically with little friction, are both operated in opposite directions alternately by means of a cog-wheel, W, of peculiar construction, supported on a shaft which bears in the boxes h h, and gearing with both racks, as shown in Figs. 1 and 2. The

. power is applied to the wheel W by means of a vertical lever, L, the lower end of which is divided so as to embrace both faces of the wheel, as shown in Figs. 2 and 6. To this end the series of cogs on the wheel are interrupted by a socket, which consists of arecess formed in each side of the wheel, and bounded laterally by projecting flanges s s. The metal of the wheel between the flanges is only about half or one-third the thickness of the wheel elsewhere, in consequence of the recesses being formed on each side, as above described. The divided handle is slipped upon this thin plate of metal and driven into place till the wood wedges firmly between the flanges s s and the end of the slot in the handle rests against the rim of the wheel. One or more rivets, t, are then inserted through the handle and thin part of the wheel, as shown in Fig. 2, and when the attachment is perfected a strong and durable connection is made between the handle and wheel, which is not liable to get out of order in any way.

My object in thus constructing the wheel W is to adapt it to receiving and firmly holding a vertical handle, L, while the wheel is in gear with a rack, R, on each side. This adapts it to this form of double pump and to the use of a vertical lever for operating the same, whereby a peculiar advantage is obtained, for with a horizontal lever one plunger must be lifted by main strength, the weight of the body not being thrown upon it, an exertion which is exceedingly arduous; whereas, with the upright lever, the weight of the body can be brought against or upon it in either direction, and therefore one plunger can be raised as easily as the other. In a single pump, where only one rack is used with the wheel, the horizontal lever may be employed, the construction of the wheel and its socket adapting it as well to one form of pump as another, and obviating the necessity, at the manufactory, of making one set of castings for single and another for double pumps.

Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent, is

The relay-pump herein described, consisting of the stocksGr G, the open vesselA divided into two compartments, as described, the boxes and valves herein described, the plunger-rods P P, the racks R It, the guides F F, the wheel W constructed with the socket, as described, and the vertical handle L, all arranged and operating in connection with each other substantially as herein set forth.
