APPARATUS FOR AGITA ING FREEZING WATER.

Application filed August 10, 1914. I Serial No. 856,016;

To all whom it may concern;

Be it known that I, EDWARD H. ALTHoEE,

a citizen of the United States, residing at Salt Lake City, county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Apparatus for Agitating Freezing IVater; and I do declare the following to be a full, clear, and exact description of. the invention, suchas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in apparatus for agitating freezing water. This invention is adapted for use in artificial ice plants, and its object is to make it practicable to freeze ice in a perfectly clear state, thus preventing the white ice which results from air bubbles in the water. Furthermore, by virtue of this agitation of the water, all impurities of a solid character are I eliminated during the freezing operation,

and gradually brought to the top of the can, where they may be separated from the ice cake.

By use of my improved apparatus continuous circulation of the water through the the medium of a suction pipe or conduit, a

corresponding quantity of water is removed from the can. In this way, the quantity of water in the can is maintained at all times, but. the circulation is continuous and uninterrupted, thus producing results superior to those attained through the instrumentality of an intermittent discharge and removal, as heretofore employed.

With reference to the apparatus, I may employ a pump of any suitable character. A centrifugal pump, for instance, may be employed to advantage. In this case, the

discharge conduit is connected with the outlet extremity of the pump, while the suction conduit is connected with the suction chamber. In this way, as the pump is operated, the water is circulated through the medium of the pump and two conduits, the one conduit continuously discharging water into the can with sufiicient force to result in the scale. y

As illustrated in the drawing, special 'apparatus 1s employed fore'supporting thedischarge and the suctlon nozzles, which are'f connected with the two conduits, thisapparatus being readily removable, from the frame work surrounding the top of the can,

can.

Fig. 5 is a perspective view of-th e appa- Let the numeral 5 designate a battery of cans in an ice freezing plant, the usual framework or supporting structure being employed. As is well understood, this is a skeleton-structure, the-top being a rectangular frame 6, into which the. top of each can fits, whereby the can is properly centered,

its lower extremity resting upon a support 7, in the bottom 8 of the brine tank. This support spaces the can from the bottom of the tank, whereby the brine is allowed to come in contact with all parts of its surface.

In my improvement as illustrated in the drawing, I employ an induction or discharge conduit 9, which extends the entire length of the battery of cans and between two rows of cans; and a suction conduit 10 also extending the entire length of the battery between the two rows of cans. This discharge pipe is connected in operative relation with a discharge nozzle 12 of each can of the two rows of cans between which a discharge or supply conduit is located. There is a short pipe 13 located below and connected with the conduit 9, as shown at 14, whereby the water passes freely from said conduit to the short pipe. From each extremity of this short pipe a branch pipe 15 leads upwardly and is secured to a beam 16 by means of a bracket 17, the branch pipe extending far enough above the bracket to permit the connection of a flexible pipe 18 therewith, as shown at 19, the opposite extremity of the flexible pipe being connected as shown at 20 with a nipple 21 threaded into a casing 22 of a valve 46, in which casing is rotatably mounted a valve piece 23, the valve having a perforation 24 which registers with the nipple 21 when the .valve is in the desired position. Threaded into the lower part of the casing 22 as shown at 25, is the depending nozzle 12, whose discharge extremity is equipped with a screw plug 27 having a reduced passage 28, whereby the discharge of water downwardly through the nozzle is retarded, as it enters a tank 29, thus increasing the force with which the water is discharged into the can, and causing the water to pass downwardly to the bottom of the can or to the bottom of the water in the can. In this nozzle 12 is located a fixed valve 30 having pointed upper and lower extremities 31 and 32. The water as it passes through the nozzle flows around this valve and passes thence downwardly through the duct 28. By the proper adjustment of the plug 27, the nozzle may be closed, since the upper part of the plug has a cone-shaped seat 33 adapted to lit the extremity 32 of the valve which is of counterpart shape.

This valve is an important feature, since it makes it practicable to accurately regulate the discharge of water into the series of cans, whereby the discharge to all of the cans shall be equal. For this reason, the discharge valves mounted on the tanks nearer the source of supply or the pump, are adjusted to reduce the available opening through the corresponding valves since the tendency would be for the water to take the shortest course and therefore enter the nearer cans in preference to those farther away. However, by retarding the flow to the nearer cans and properly graduating the retarding influence by the proper adjustment of the various valves 23, the discharge into each can of the entire battery may be equalized. For the purpose of regulating each of these valves a removable key 34 may be employed. This key is provided with a socket 35 adapted to fit the exposed extremity 36 of the valve piece 23, said valve piece extremity being polygonal in cross section and the key socket of corresponding shape. Surrounding a collar 37 formed in the valve casing 22 is an adjustable collar 38, which is secured in the desired position of adjustment by a set bolt 39 passing through a curved slot 40 formed in the collar. This collar is provided with a stop pin 41 located in the path of a projection 42 formed on the handle 43 of the key. The object of the stop pin 41 and the adjustable collar 38 carrying the said pin, is to make it practicable to set the construction so that when the key is actuated to bring its lock 42 into engagement with the stop pin 41, the person in charge will know that the valve piece 23 is properly adjusted for the corresponding can, having reference to the location of the latter or its distance from the source of supply. When it is desired to manipulate the valve with reference to this adjustment, it is only necessary to reverse the position of the handle from that shown in Fig. 3, whereby the projection 42 extends away from the valve casing, in which event, the key may be manipulated without en gaging the stop pin. It will be noted by reference to Fig. 3, that the key is reversible as the socket extends entirely through the head of the key.

Arranged below the suction conduit 10 is a short pipe 4 from each extremity of which a branch pipe 44 extends upwardly and is connected with one extremity of a flexible pipe 45 whose opposite extremity is connected with the nipple of a valve 47. Within this casing is located. a valve piece 23 which is substantially of the same construction as that heretofore described when speaking of the valve 46. In other words, the mechanism of the valves 46 and 47 are substantially the same, both as regards their construction and the manner of their adjustment, the reference character 46 being em ployed to designate the valve mechanism in its entirety, which is connected with the discharge pipe 18, while the reference character 47 is employed to designate in its entirety the valve mechanism connected with the suction pipe 45. The suction nozzle will be designated by the numeral 48 in Fig. 3, since this nozzle is slightly different in construction from the discharge nozzle 12, as the latter is provided with the retarding plug 27, while this feature is absent in the suction nozzle. With this exception, the entire discharge and suction features employed in connection with each tank, are of the same construction and the description heretofore given when speaking of the parts of the valve 46 is equally applicable to the same parts of the valve 17, the construction being shown in detail in Fig. 3.

In order to properly support the discharge and the suction nozzles, I employ a spider device 49 which consists of a circular member 50 centrally arranged at the top of the can and having arms 51 and 52 connected therewith and leading outwardly therefrom, their outer extremities being hook-shaped as shown at 53, to engage the can and the surrounding frame work 6 on opposite sides. In thismanner, the circular device is rigidly supported at the top of each can, but is at the same time, readily detachable therefrom. In order to further maintain each spider device 419 in cooperative relation with its corresponding can, I employ spring hooks 54 which are connected with the arms 51 on each side of the circular device 50, the arms 51 being bent to form eyes 55 with which the eye extremities 56 of the hooks are interlocked. These hooks are inserted in openings 57 formed in the can and the registering openings 58 formed in the frame 6. These hooks are placed under sufiicient tension as they are crowded into the openings, to cause them to remain in position until removed by design.

While I have now described the suction and the discharge apparatus connected with poses with the two corresponding conduits 9.

and 10, in the samemanner as heretofore described, the parts being shown in detail in Figs. 2 and 6, inclusive. Hence, when the invention is in use, there is a continuous and equable discharge toreach can of the bat- V tery and acontinuous and equable exhaust from each can of 'the'battery, this being brought about through the instrumentality of the valve mechanism 16 and 17. 1

' As illustrated in the drawing see Fig. 1), a pump 59 is employed, its discharge opening 60 being in communication through a pipe 61 with a branch pipe 62 whose opposite extremities are connected with the two conduits 9 of the battery 5; while the suction opening of the pump is connected by means of a pipe 63 and a branch pipe 64: with the two suction conduits 10 of the battery 5.
