MEANS FOR SUPPLYING WATER UNDER CONSTANT PRESSURE T0 FREEZING-PLATES.
Specification of Letters Patent.
Patented July 25, 1905.
Application filed July 28, 1904- Serial No. 218,463.
T0 at whom it may concern.-
Be it known that I, EDWARD BARRATH, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Means for Supplying Water Under Constant Pressure to Freezing-Plates, of which the following is a specification. Y
My invention has relation to a means for supplying water under pressure and in substantially a quiescent or unagitated state to freezing-plates in the manufacture of ice by a system of substantially the type illustrated and described in United States Letters Patent No. 710,656, granted to me under date of October 7, 1902. In the system described in said Patent No. 710,656 water'from a receptacle flows in a thin film over a freezing-plate and the block or plate of ice is formed on the freezing-plate by successive accretions. In such a system where a series of freezing-plates or even a single freezing-plate was used some difliculty has been experienced in maintain ing a constant pressure of water in the receptacle or receptacles, as well as a constant flow thereto, and hence the formationof the block of ice has not been regulated to economically utilize the power.
The object of my present invention is to provide a means whereby the pressure and flow of water to the receptacle or receptacles may be maintained constant; and to this end my invention consists, essentially, in feeding the water to the receptacle or receptacles through valve-controlled inlets from a main reservoir in which the water is maintained under uniform pressure, the main reservoir being fed from a source of supply, such as an elevated tank, into which the water-feed pump discharges.
The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawing, forming part hereof, which illustrates, partly in elevation and partly in vertical section, an apparatus for embodying main features of my invention.
Referring to the drawing, (t represents the freezing-plate, and Z) the receptacle adjacent to one end of said plate and containing the liquid adapted to overflow upon said plate a to form by successive accretions the block of ice. As illustrated in the drawing, two series of these plates a and receptacles I) are connected with a centrally-disposed reservoir 05 by valve-controlled pipes cl. The reser- Voir (Z is supplied and held continually filled with liquid through a valve-controlled pipe (Z leading from a tank 6, elevated by preference some distance above the plates at. In the tank 6 is arranged an overflow stand-pipe 6, leading to a collecting tank or reservoirf, from which and a supply-pipe /L2 the pump 9 receives its liquid-supply. The liquid in the elevated tank 0 maintains the liquid in the reservoir (Z, arranged between and extending slightly above and below the freezing-plates a, under a constant and uniform pressure.
Furthermore, by this'arrangement of the reservoir d below the tank 0, receiving the liquidsupply from the pump g directly, the liquid in the reservoir will be held in substantially a quiescent or unagitated state, as the disturbance of the liquid in the tank e cannot be transmitted to the reservoir (Z and from the same to the receptacles or containers 6. The reservoir (Z, being always filled with liquid from the tank 6, will act as an equalizer of the variation of the pressures produced by the varying levels of liquid in the tank 0. The pump g forces the liquid from the reservoir f and the supply-pipe k through the pipe 9 into the tank 6. The inflow of the fluid into the tank 6 by means of the pump 9 is such as that the fluidin this tank is always under more or less constant agitation, especially about the upper portion of the body of fluid therein. This agitation would naturally prevent a regular or constant pressure being maintained in the reservoir d and receptacles b, and if this agitation were transmitted to the reservoir (Z would seriously interfere with the rapid freezing of the fluid into ice on the freezing-plates a. It is therefore necessary that the fluid should be stilled or brought to asubstantially quiescent or unagitated condition before reaching these plates for insuring a proper freezing or congealing of the fluid into needleless and. clear plate-ice. The water in the tank 6 will be stilled, due to the fact that the agitation diminishes in the direction of the bottom of the tank and prior to its discharge through the contracted pipe (Z2 to the stilled fluid-reservoir d, in which the fluid is permitted to spread out therein .prior to its flow 1b in required quantities. ment, no matter what the fluctuation in the pump 9 may be, it is corrected primarily inthrough the pipes cl to the receptacles I) and thence over the series of plates a. The overflow from the plates a is collected-in troughs It and led by the pipes h to the collectingtank or reservoir f. At the base of the reservoir (Z is arranged a draw ofl cock d, through which sediment or impure water-may be discharged when the reservoir (Z is to be cleaned. At the top of the reservoir (Z is arranged an air-outlet (Z through which air in the reservoir (Z may escape, so as to insure the complete filling of the same with liquid.
The operation of the device isas follows: The main reservoir (Z is lilled with liquid from the tank 6, in which tank the liquid is maintained at prescribed height (and consequent pressure) by the overflow-pipe 6'. When the reservoir (Z is once filled, the valve on the pipe (Z is set and the valves on the pipes cl are opened to admit the water to the receptacles With this arrangethe tank a and secondarily in the main reservoir d, so that water under constant pressure and in required volume enters a receptacle or receptacles 7).
Having thus described the nature and ob ject of my invention, what I claim as new, and desire to secure by Letters Patent, is
1. An apparatus for the manufacture of plate-ice, comprising a series of freezingplates, a receptacle for fluid arranged adjacent to one end of each of said plates, a reservoir for containing fluid under constant pressure and in substantially a quiescent or unagitated state for supplying the same in such condition to said plates, and a tank for the fluid in an agitated state in communication with said reservoir, said tank arranged to control the pressure of the fluid in said reservoir and to still the same prior to its delivcry to said reservoir,- receptacles and plates.
2.
