TO ALL WHOM IT MAY CONCERN:'
Bef it known that. we,.RoBERT GILLILAXD and R. I-I. ARMSTRONG, of Hudson, in' the county of Lenawee,
vand'in the State of Michigan, have invented certain new'and useful Improvements in Pumps; anddo hereby declare that thc following is a full, clear, and exacti description thereof, referencebeing had Vto the accompanying drawings, and to the letters of reference marked thereon In the annexed drawings,making part of this specification, A represents the pump-stock, and B andV C represent two short cylinders, which connect with it nca'r its bottoni. The stock and cylinders may be secured together in any'suhstantial manner, but we prefer to use a metallic strap, G, seen in Figure 3, surrounding them, and tightened by means of a wedge, Il. The pump-rodD, with a plunger on.its lower end,pplays in the cylinder B. This cylinderis provided with four valves, a, d, e, and t'. Two of these, a andsd, open into the stock A, and thc other two open into the cylinder C, asscen at e and z'.
The water from the well is received into cylinder C through its lower end, which s open. Ateach up stroke ofthe piston-rodwatcr passes under the plunger lthrough valve z', and the water above the plungerpasses out into stock A vthrough valve a. At each down stroke of the rod D, water enters above the plunger, through valve d,and out below the plunger, at valve e, into the'stock.
E represents a metallicor other suitable box, which'is secured upon the upper end of the cylinderiB. '.lhe piston-rod D passes through this box, openings being prepared for it, into which it ts water-tight. Water is Y "inserted in the box E, 'and acts as a packing around the piston-rod, to preventthe passage of air to or from the chamber of cylinder B. By means of this box, with its'water-packing, a very secureand effective packing is formed.
It will be seen that the .bottom of the box E is provided with'a small valve, (see FigureL) so that the action of :thepiston forces the water into this chamber, causing an everlasting packing for and around'the piston-rod without placing the working parts of the pump under water. By the arrangement of the sections AVB C, with the piston in the centre section, we form a double-action force and suction-pump.
Having tlus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
`The arrangement Aof the water-chamber E, upon the top of section B, for causing a cold-water packing,
4which is formed by the operation ofthe pump, and constitutes a doublc-acting force and suction-pump, without placing the working parts under water, as set forth.
In testimony that we claim the foregoing, we have hereunto set our hands, this 2d day of September, 1867.
ROBT GILLILAND, R. H. ARMSTRONG.
