DIA HRAGM-Pomp.
Specification of Letters Patent.
Patented April 23, 1907.
. Application filed July 17,1905 SerialNo. 269.914.
I To all whom it may concern:
- which the following is a specification.
, and whic My invention relates to diaphragm pumps, and it has for its general object the provision of a pum which is simple in construction, When combined with an internal combustion motor, maybe operated most successfully, and with a very small amount of power, for continuously pumping water,
for example through the water jacket of the cylinder of the motor, for the pur se of coolin the cylinder.
In the drawings illustrating the principle of my invention, and the best mode now known to me of embodying that principle in operative means, is shown-an internal combustion motor, having the usual shaft A, crank B, piston 0, cylinder D and connecting rod E connecting the piston O, and crank B. The cylinder has a water jacket Forming a portion of crank amber 1 is a diaphragm 2, preferably of sprlng brass. It is mounted and clamped as tor example between two acking rings 3 which are secured in any well nown way to the wall portion of e crank chamber, as by pump casing 4, and bolts 5. A ump chamber 6 is formed between the diaphragm 2 and pump casing 4,
the latter of which has two openings 7,,8,
therein; one 7, leading froman inlet valve chamber 9' into the pump chamber '6; and
the other 8, leading from the pump chamber 6, into the outlet valve chamber 10,. An inlet valve'll controls an opening 12 leading from a source of water supply 13 while an outlet valve 14 controls the opening 8 leading to the 111111) chamber 10, from which a \pi e 15 lea s, as to' the water'jacket F of the cy inder D. The construction of the valves, and their operations are so obvious from an inspection ofthe drawings that a description is omitted.
plain.
piston C, cause alternate rarefactions and compressions of the atmosphere in the crank chamber 1; consequently the diaphragm 2 moves to and fro, and assumes positions 16, and 17, which are exaggerated, for the sake of clearness. When the diaphragm 2 moves to position 16, there is a tendency to form a vacuum in the pump chamber 6; atmospheric pressure in the supply pipe 13 forces open t e inlet valve 11, and water rushes into the inlet valve chamber 9, and the pump chamber 6 until e uilibrium between the liquid on each side 0 the inlet valve 11 results;
the outlet valve 14 during the rarefaction in the pump chamber 1 always closing the out- I let opening 8. The moment the piston C begins to descend, the atmosphere in the crank chamber 1 becomes more compressed, and pushing outwardly against the diaphragm 2, tends to move it to position 17. This pressure actingva-gainst the water in the pump chamber 6, forces open the outlet valve 14, and the water. rushes into outlet valve chamber 10, and hence through the outlet pipe 15,
into the water jacket-F, until equilibrium is restored,between the pressure in the pump chamber 6 and-that in the outlet chamber 10; the inlet valve 11 of course; during the down stroke of the piston 0, closing the opening from the inlet valve chamber 9 to the source of water supply 13. In fine, the continuous alternate up and down strokes of the piston 0 cause in the crank chamber 1, alternate rarefactions and compressions of the air in the crank chamber 1, and the diaphragm responding to these changes and producing similar changes in the pump chamber 6, causes valves 11, 14, to permit water to be drawn from the source of supply and forced to'the lace where the water is desired.
A Whi e my inventionis extremely useful when it'is used in connection with an internal combustion motor, as for the purpose of cooling the cylinder of the motor, yet obvilet of the water jacket, and when necessary, providing means to remove the heat of the water after leaving the water jacket, one may have a continuous circulation through the pump and the water jacket.
Further, y connecting the supply pipe with the out-' I have found my invention very useful when applied to motors for driving boats,
but I do not wish to limit it to any particular use, for it'may be combined with all kinds of internal combustion motors, whatever be the purpose for which they may be employed.
While my invention may be embodied in many forms, I do not wish to limit my invention to the particular construction shown and described, but desire to protect it in the broadestmanner legally possible.
What I claim is 1-- In an internal combustion motor, a casing having a crank chamber; a metallic diahragm'forming one side of said crank chamher, and closing and rendering said chamber air tight; a pump casing formed in one piece of metal, and, when combined with the diaer; means for securing said diaphragm and leading from the said pump casing to said crank chamber casing and forming thereby said air tight crank chamber and-said air tight pump chamber; said pump casing having formed therein, an
inlet valve,chamber; an outlet valve chamber; openings leading from said valve chambers into said pump chamber; an inlet to said inlet valve chamber; and an outlet from said outlet valve chamber; an inlet valve to control said inlet to said inlet valve chamber; and an outlet valve to control the opening pump chamber to the outlet valve chamber.
In testimony whereof I afiix my signature in presence of two witnesses. GEORGE JOHN ALTHAM. Witnesssz' PHILIP E. TRIPP,
