JOHN H. MCGOWAN AND THEODORE J. MCGOWAN, O1" CINGINNA'II, OHIO.
Letters Patent No. 70,733, dated November 12,1867. v
IMPROVBMEN T IN PUMPS.
TO ALL WHOM -IT MAY ONC/EBN: Be it known that we, JOHN H. McGOWAN and THEODORE J. McGOWAN, both of Cincinnati, Hamilton county,
State of Ohio, have invented a certain new and useful Improvement in Suction-Pumps; and we do hereby' declare the following to be a full, clear, and exact description thereof, reference being had tothe accompanying drawings, making part of this specification.
Our invention consists in so constructing the suction-coupling of an ordinary suction-pump that it is made to surround the pump-barrel, the space between the -barrel and coupling being designed as a primingchamber,
which, as it'has no. connection at the bottom with the suction pipe, always remains full yof water, and ykeeps'the .pump fully primed, and the bucket, at the lowest position of its stroke, totally immersed in the water, though the suction may be leaky, and run dry after every operation. In the accompanying drawings- Figure 1 is an elevation of a common suction-pump', with our su'ctiomcouplinig in section. The pump in this figure is supposed to be vat rest.
Figure Z'exhibits an axial section of pump and coupling inaction. Figure 3 isa horizontal section, showing the eonstructionofthe priming-chamber.
A 'is the vpump-barrel; B, the discharge pipe; C, the bucket, and D the bucket-rod. E is the suctoni coupling, which has nodircct opening at the bottom, but has an enclosed V-shaped duct or passage, E', formed in its bottom and sides, to which the suction `pipe G connects, us shown. The coupling E is connected to thc. pump, near the top of the latter, by meansA of hanches a e, on pump and coupling respectively, the pump being suspended within the coupling, as'sihowin so th-at,when the lutter is charged with water, the pump-piston, at its lowest position, shallbe totally and permanently immersed` .Permanent priming, as is well known, keeps the leathers soft, and renders them more durable, and tends to insure a speedy and eti'cicnt suction, though the connectionsmay be leakyand run di'y It will be seeny that, in our device for permanent priming, the water will remain in the chambercoupling E, though the pipe G may be leaky and run dry, asin tig. 1; or that eith-er the pipe G or pump A may be removed for repairs at will, without disturbing the Water in the chamber. i
We ela-im herein as new and of our inventionv p A suction-pipe coupling, E E', in connection with a pump-cylinder or cylinders, A, s o constructed as that, when attached to the pump, it will form a reservoir, which will maintain a constant supply of water, and in which the pump-cylinder is partly or wholly submerged, substantially as described and for the purpose specilied.- In testimony of `which invention we hereunto set our hands` l L JOHN H. McGOWAN,
THEODORE J. MOGOWAN.
