Letters Patent No. 84,355, dated November 24, 1868.
'IMPROVEMENT IN PUMPS.
The'Schedule referred to in these Letters Patent and making part of the same.
To all whom 'it may concern.-
Beit known that L THOMAS HANsBRow, of Sacrament'o, in the county of Sacramento, and State of California, have invented a new and useful Improvement in Double-Action Pumps; and I do hereby declare that the following is a full, clear7 and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had tothe accompanying drawings, forming part of this specification.
This Iinvention relates to a new and improved method of constructing pumps of the double-action kind, whereby they are greatly simplied in their construction, and renderedmore durable, and less liable to leak; and
The invention consists mainly in locating the valves at or near the top of the barrel of the pump, Aand in the manner in which the valves are hung in the valvechambers, and secured therein, as will be hereinafter described.`
Figure 1 represents a vertical longitudinal 4section of the pump, through the line a: @of iig. 2, showing .the manner in which the pump is constructed.
Figure 2 is a horizontal view of iig. l, through the line y y- Figure 3 is a longitudinal section of g. 1., through the line z z.
Similar letters of reference indicate corresponding' parts.
A is the barrel or cylinder of the pump.
B represents the water-chest, which is connected directly with the barrel, at the bottom, and with the air-chamber, through valve-chambers, at the top.
C C are the lower valve-chambers, and
D is the upper valve-chamber E is the air-chamber.
A very important featureof my invention consists -in the arrangement of the valves, at or near the upper end'of the barrel, from which it will be seen that no leakage of the valves can deprive the pump of water, so that primingfby hand, is entirely unnecessary. The valves in this position are, moreover, much easier managed or cleaned. Y
Another important feature, and one which greatly simplifies the construction and operation of the valves is, the manner in which they are hinged or secured in the valve-chambers.
F represents the valves, which are simply metallic plates, with leather packing, and with pivots cast or attached to'two of their corners, as seen in dotted lines in fig. 2, at a.
There are recesses cast or formed in the outer case or walls of the valve-chambers, as seen in the drawings, which admit these pivots, and these recesses are of such a form that the pivots have play up and down, so that they can always adjust themselves to their seats.
The valvesare held in place, and the valve-chambers are closed by the cover or plate marked G, which is held to its place and secured by a central screw-bolt, which is firmly attached to the partitions, as seen in the drawing.
AThe central screw-bolt is marked h, and i is a nut upon the bolt.
This plate has ribs, whichv radiate from the centre, more or less in number, which serve to strengthen or stiifen it.
J represent these ribs,
AIn large pumps, a cross or spider may be applied, secured to the plate by a central screw-bolt, with its arms bearingupon the four corners.
The lower valve-chambers C C are divided by the partition k, as seen in lig. 2, which compartments form two distinct valve-chambers, one of which'is connected with the top of the barrel, and the other with its bottom, through the water-chest B.
Below these two valve-chambers there is a waterchamber, L, (iig. 1,) which communicates with both bolts or pins upon each side, which bolts are fitted in holes drilled for that purpose. u
This method of attaching the Valves is defective, because it makes a tight-jointed hinge, liable to corrode and become inoperative.
Ifthe leather facing is-used upon this valve, the hinge will not permit the valve to accommodate itself to inequalities of surface, for the reason that one side of the hinge is liable to Wear faster than the other, through the action of sand in thevvater being pumped. By my invention this difcultyis avoided.
The valve is not only allowed to swing freely upon the bolts, but the latter are permitted to Work in a vertical direction, allowing the sand to pass behind the heel of the valve, and prevent'the .clogging of the same.
Having thus described my invention,
I Iclaim as new, and desire to secure by Letters Patent- 1. The valves F, whenrtheir pivots, a, are adapted to fit in recesses formed in the walls of the valvechamber, whereby the heel of said valvesv has a vertical play while swinging upon said pivots, as h'erein described for the purpose speciiied.
2. The pump-barrel A, water-chest B, and valvechest, all cast in one piece, and arranged as described, for the purpose specified.'
THOS. HANSBROW.
