Specification of Letters Patent.

Application filed March 18, 1915. Serial No. 14,211.

To all whom it may concern:

Be it known that I, JoHN H. POOLE, a citizen of the United States, residing at Jamaica, in the county of Queens and State h of New York, have invented certain new and useful Improvements in Ice-Forming Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in apparatus for use in the artificial production of ice, and relates particularly to the manufacture of raw water, can ice.

To those familiar with the art to which this invention appertains, it iswell known that the water in the freezing tank is agitated by means of air passing through a system of piping and issuing from tubes or the like that extend down into the tank and I the water contained therein. In the practice heretofore employed, a plurality of distributing pipes are used, the number and arrangement depending manifestly upon the number of tanks and the arrangement of the latter, any desired number. of laterals or branch pipes being connected to the distributing pipes and extending down into the tanks. Usually these branch pipes have been made substantially in the form of yokes detachably connected to the distributing pipes at points where check-valves are provided, the branch pipes having metallic sections or extension members projecting down into the water. At a predetermined point in the congealing of the water it has been customary to withdraw these bran'chpipes and their extensions, but from actual experience I have found that difliculties have been often encountered, owing to the fact. that the water had congealed to such a point that when the operators attempted to withdraw from the tanks the downwardly projecting metallic pipe sections, the joints between the same and the main branch pipes or laterals have become detached, whereupon there have been left, within the blocks of ice, relatively long sections of pipes' that have thus become irreparably lost. This one instance alone has been found to be a very material factor in increasing the cost of the output, while at the same time the construction of these distributing pipes with their check valves mounted therein as well as the construction and arrangement of'the other parts of the system above thus generally outlined, have tended to make the cost of maintenance and installation relatively high.

With a knowledge of these conditions my invention has for its primary object a simple, durable and efficient construction of parts, and arrangements thereof, whereby, in the first place, the cost of the output is materially reduced, owing to the fact that the branch pipes used to convey the air from the distributing pipes down into the tanks are provided with extension members formed of some frangible substance or material not detrimental to the ice and capable of being very cheaply made, so that the manufacturer can afford to leave these extension members or tubes in the ice by merely cutting them or breaking them off at a short distance above the upper surface of the ice block.

A further object of the invention is to provide means whereby the cost of installa- Patented Mar. 21, 1916.

tion and maintenance is reduced, owing to v the fact that with my'invention, the check valves above referred to are dispensed with, as will be hereinafter more fully described. And the invention also aims to generally improve devices of this character so as to render them more useful and commercially desirable.

With theseand other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter more fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in

Figure 1 is a perspective view, in the nature of a diagram, illustrating the application of my invention, the branch pipe 3 being somewhat enlarged; Fig. 2 is a detail view illustrating two of the branch'pipes in side elevation over portions of the tanks; 'Fig. 3 embodies two sectional views of one of the tanks, showing the different stages in the freezing of the ice; Fig. 4: is an enlarged sectional side elevation of one of the branch pipes and its downwardly projecting extension member, and Fig. 5 is a detail view showing the air-tight closure, which, when opened,will permit the insertion of the frangible extension member.

Corresponding and like parts are referred to in the following descri tion and desigfnated in all of the views 0 the'accompanythere being one pair for every two tanks,-

said nipples terminating in vertical planes wardly turned short of the adjoining side walls of the tanks, whereby. the latter may be readily removed whenever desired.

My improved branch pipes 3 are arranged for detachable connection to the nipples 4 of the distributing pipes 2, and in order to provide for the expeditious attachment and detachment of the branch pipes, they are in the present instance shown as provided at one end with clamping arms 5, arranged in diametrically opposite relation to each other and pivoted intermediate of their ends to form handle portions 6, said clamping arms being spring pressed in closed position and their extremities being adapted to extend around and engage annular collars 7 formed on the extremities ofthe nipples 4. Preferably the branch pipes 3 carry washers 8 adapted to fit upon hollow bosses 9 and to abut against the outer faces of the nipples 4 when the pipes 3 are secured in their operative positions, whereby a tight joint will be produced.

Operatively connected to the branch pipes 3 are extension members 10 in the form of pipes or tubes, these in the present embodiment of the inventive idea, being preferably detachably connected to the downwardly projecting outer ends 3 of the pipes 3, the lower extremities 3" of these downends, being preferably tapered, as best illustrated in Fig. 4. The

extension members 10 are formed with flared or bell-shaped upper ends 11 adapted to fitwithin the lower extremities 3" just mentioned, whereby the pipes 3 and their extension members 10 will be operatively connected together in a readily detachable manner.

In order to provide for the ready connec-* tion of the parts 3 and 10, openings are formed in the former at the juncture of the main body portions thereof with the downwardly turned ends, and spring-pressed closures 12 normally cover said openings in anair-tight manner, whereby it is only necessary to move the closures to an open position and insert the extension member 10 .ing'- apparatus? will be apparent.

. down through the openings when they will come to rest with the parts in their operative relatio lustrated best in Fig. 4. a

F-ron'i' iifth regoing description in connection a h the accompanying drawing, the operation of my improved ice manufactur- In the practicalusei iof the device, after, the tanks have been disposed in their proper positions, the branch pipes 3 and their extension members 10 are operatively placed, and whenever it is necessary to remove the pipes 3, all the operator has to do is to press together v the handle portions of the clamping arms 5 from the collars 7 of the to release the nipples 4. T t he branch pipes 3 (or, if desired, even. efore they aj etached from the nipples 4,) can be iea iy separated from their extension members 10, the latter" being left in the ice blocks, for'said extension members are, as hereinbefore specified, composed of any suitable easily frangible non-metallic substance or material that can be cheaply made and not be detrimental to the quality of the ice. Usually, only about three of the tanks are removed at the same time, and consequently the ni ples thus opened may be permitted'toizffjblow, for the amount of air thus wasted ispractically negligible. Hence, no checkvalves are required, and this in itself tends to reduce the cost of installation and maintenance.

It will thus be seen that I have provided a very simple and eificient construction and arrangement of parts whereby the tubes or pipe extensions that extend down into the tanks or blocks of ice formed therein, may

be left within the ice, as the cost thereof isvery small and that my invention not only results in material economies in the cost of trates what I believe to be the preferred em-' bodiment of my invention, it is to be under stood. that the invention is not limited thereto but that various changes may be made in the construction, arrangements and proportions of the parts without departing from the scope of the invention as definedin the appended claims.

- What is claimed, is:

1. In an ice forming apparatus of the character described, an air dlstributing pipe and a branch therefor, the branch being provided with a downwardlyprojecting end having. a tapered lower extremity, and a frangible extension member having a flared upper end adapted to fit within said extremity, for the purpose specified.

2. In an ice forming a' paratus of the character described, an air istributing pipe, a branch therefor having a downwardly adapted to detachably connect the branch pipe to said nipple, said branch pipe being formed with a downwardly extendlng end, and a frangible extension member connected to said end, as and for the purpose set forth.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

JOHN H. POOLE.
