WATER-SUBMERGED AIR-CHAMBER FOR WATER-PIPES.
Specification of Letters Patent.
Patented June 8, 1920.
Application filed July 14, 1919. Serial 110/310,?00.
To all whom it may concern:
Be itknown that I, HOWARD H. YORK, a citizen of the United States, residin Logansport, in the county of Cass and btate of Indiana, have invented certain new and useful Improvements in Water-Submerged Air-Chambers for Water-Pipes, of which the following is a specification.
This invention relates to a device for cushioning hydraulic impacts in water pipes, being an improvement on my former U. S. Letters Patent No. 1,216,761 issued Feb. 20, 1917; and one of the objects of the present invention is to provide a more sensitive and eflicient device for absorbing hydraulic impacts than obtains in my former patent.
A further object of the invention consists in the provision of a device of the above character wherein a number of chambers are submerged within the water, said chambers being arranged at different distances from the main water line and adapted to hold a quantity of air, and all of said chambers having air communicating passageways between them so that hydraulic impacts are gradually absorbed without jar and noise.
A still further object of the invention consists in the provision of a device of the above character in which the loss of air may be easily replaced, when necessary.
I accomplish the above objects of. the invention, and such others as may appear from a perusal of the following description and claims, by means of the construction illustrated in the accompanying drawings,
. forming a part hereof, in which Figure 1 is a central vertical sectional view through the tank, the air holding chambers being shown in elevation. Fig. 2 is a horizontal section through the tank, on the line 2-2 in Fig. 1. Fig. 3 is a perspective View of one of the air holding chambers or cups, the remaining parts of the device being omitted. Fig. 4: is a fragmentary detail View in side elevation of one of the cups, showing the means for supporting in operative position.
eferring to the drawings, 10 represents a water service pipe for conducting the water to the points of consumption. Interposed in service pipe 10 at a suitable point is a lateral pipe 11 which communicates with tank 12, the latter being closed at the top and open at the bottom for the introdevice is far more duction of the internal parts into the hollow chamber l3.' The lower and open end of tank 12 is closed by means of a plate 15 which is secured to the annular flange 16 of tank 12 by means of the bolts 17.
Arranged centrally within the hollow portion of tank 12 is a series of uniformly spaced air holding inverted cups 20 which are arranged seriatz'm in a vertical plane. Cups 20 are retained in position relatively to one another by means of a plurality of vertically disposed rods 21 and screws 22 which pass through apertures 23 in said rods and enter threaded apertures 24 in the integral ears 25'depending from the lower edges of cups 20. Each of the supporting rods is provided with a plurality of spaced apertures 23 to enable cups 20 to be spaced a greater or less distance apart, and rods 21 are held in spaced relationship by introducing their upper ends into sockets 27 in the closedend of cups 20 and their lower ends into sockets 28 in plate 15.
In practice, the hollow portion or chamber 13 of tank 12 and cups 20 is full of air when the device is introduced into the service pipe 10. YVhen the water is turned on tank 12 will fill with water and the air in cups 20will be placed under compression. The hollow portion confining the air in one cup communicates with the air chamber of' the next cup by means of a pipe 30, whereby direct communication is established between the air holding chambers of all the cups, so that shock of impact delivered by the back pressure, as when the flow of water at a faucet is suddenly discontinued, is absorbed by the cushioning effect of the air confined in the various cups 20.
practice, that the present sensitive and the effect of impact, induced by back pressure, is more effectively absorbed when delivered to air confined in aplurality of distinct air holding chambers or pockets arranged more or less remotely from the point of egress of the back ressure in the tank, sothat air in the pocki gts will be affected alternately, than obtained in my former device where the impact was delivered upon the aircontined in a single pocket, it being immaterial whether the surface area of the single I have found in pocket equaled the combined surface area of several pockets in the. present device.
Loss of air below the normal requirement forthe efficient operation of the device may I Filling pipe 32 passes through plate 15 and projects into the hollow chamber in lower desirable to do so.
' air into the latter.
The device is also provided at the bottom with a drain cock through which the water in chamber 13 and the interior of pipe 10 may be drained when itis founddescribed my said in- Having thus fully secure by Letters vention, what I desire to Patent, is
1. The combination with a water service pipe, of a closedwater tank having its interior in communication with the interior of the service pipe, and a plurality of spaced air tanks arranged scriatim' and submerged within the water tank, and a pipe extending from outside the water tank and into the interior of the air tanks for introducing 2. The combination with-a water service pipe, of a closed water tank having its interior in communication with the interior 1 lnto the lnterlor of the all tanks.
of the service pipe, and a plurality of spaced air plane parallel with the inlet to said water "tank for alternately checking the impact of back pressure.
3. he combination with a water service pipe, of a 'closed water tank having its intanks arranged seriatim and in a terior in communication with the interior of the service pipe, a plurality of spaced air tanks arranged serz'atim and in a plane parallel with the inlet to said water tank.
for alternately checking the impact of back pressure, and means for supporting the air tanks in determined relationship to one another within the-water tank.
4. The combination with a water service pipe, of a closed water tank having its interior in communication with the interior .of the service pipe, a plurality of spaced air tanks arranged seriatim within the water tank and in a plane parallel with the inlet to said water tank for alternately cushioning the effect of back pressure, means for supporting the air tanks in determined re-' the supports, and means or introducing air Inwitness whereof I have hereunto set my hand and seal at Logansport, Indiana, this 2nd day of July, A. nine hundred and nineteen.
