P. HESSEL. IGE MACHINE. APPLICATION FILED JULY 3!, 19 20- Patented Nov. 1 1921.

ICE-MACHINE.

Application filed July 31,

To all whom it may concern:

Be it known that I, Pmmr HnssEL, a citizen of the United States of America, and a resident of Norfolk, county of Norfolk, and State of Virginia, have invented certain new anduseful Improvements in Ice-Machines, ofwhich the following is a full and clear specification.

It is the common practice in the manufacture of raw water ice in cans to continuously inject centrally into the water in each can, during the freezing operation a fine stream of air for the purpose of aerating the water during the process of freezing, to thus prevent the formation of a core or pipe of white ice, which core would render the ice-block unme'rchantable. This is now done by a small air-tube depending into the water, this tube being connected to an air-pipe-line in any suitable manner. After the block is frozen, the tube is withdrawn from the ice and is used again in another operation. The withdrawal of these tubes from the ice-block is a troublesome matter,

as is also the Work of disconnecting the tubes from the fitting connected to the air supply-pipe; these metal tubes are further objectionable for the reason that they quickly become unsanitary and thus requlre cleaning from time to time.

It is the object of my invention to en tirely do away with the above-mentioned objections and troubles and provide 311 3411- injecting means that will be simple, inexpensive and sanitary, as more fully hereinafter set forth. I

The drawing is a view in which is represented partly in side elevation and partly in vertical section a sufiicient number of parts of an ice-making machine to illustrate myinvention.

In the drawing, a designates an ordinary ice-can, Z) a rubber hose supported on the rim of the can by means of a clamp c and adapted to be connected to a pipe-line for supplying air under pressure in the usual' manner. Clamped in the end of the hose overhanging the pan is a downwardlyturned metal elbow-tube d, this tube being removably secured in the end of the hose by means of a clamp e.

inserted in the downwardly-extended end of the elbow (Z is a tube 7' of small diameter, which depends into the water in *1 the can for the usual distance and so as to deliver continuously a fine stream of air Specification of Letters Patent.

sired degree of stiffness and also render it substantially water-proof. The coating of paraffin on the tube serves to seal the upper end of the tube in the elbow d by the simple act ofin'serting it in the elbow, while at the same time the tube may be readily slipped out of the elbow after the freezing operation is completed. It is theidea of the invention to use these tubes but once, they being so inexpensive that it is practlcable to do this, so that each tube will be thoroughly sanitary and therefore will avoid contaminating the ice.

The flexibility of the tube permits the upper end to be readily deflected'or bent so as to-disconnect it therefrom after the block is completely frozen, and this may be done whether or not the tube is pulled out of the ice-block. The tube may be permitted to remain in the block, as it will not add apprec1ably to its weight and will not detract from the appearance of the block; but if desired the tube may be withdrawn readily from the block, as the parafiin is inherently frost-repellent and willthus prevent sticking to the ice.

It will be understood that any other material similar to paper may be employed for forming the tube, and it will be understood also that I may provide the paraflin coating with an additional coating for still further assuring frost-repellent action, to thereby render certain and easy the withdrawal of the tube from the block. For instance, for this purpose the tubes may be thinly coated with an edible oil. it is believed, however, that most manufacturers of ice would be entirely willing that the tubes remain in the blocks, as they do not afiect the merchantable appearance of the ice, they being in fact so inconspicuous as to be practically unnoticeable, and, further, because this parafiin-paper type of straw is known to the public to be thoroughly sanitary; therefore the presence of the tubes in the ice-blocks would not meet with any objection on the part of the public. Obviously, the ,embedded tubes would not interfere in the least with the splitting up of the block of ice into smaller pieces in the usual manner, as the tubes are so inherently weak that they will plane of. severance of 10 impregnated with parafiin.

2. In an ice machine of the type set forth, a downwardly-turnedsupporting-tube, and a delivery-tube made of paraffin-coated paper having its upper end fitted up into said depending supporting-tube, the coating on the tube serving to seal the end thereof in said delivery-tube.

In testimony whereof I hereunto afiix my signature.
