APPARATUS FOR MANUFACTUBTNG ICE.

Application filed March 29, 1915. Serial No: 17,617.

v T all whom it may concern Be it known that I, WILLIS B. KIRK- PATRICK, a citizen of the United States of America, residing in the city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Apparatus "for-Manufacturing Ice, of which the following is a specification.

This invention relates to an improvement in apparatus for manufacturing raw water ice of the general type described in my copending application No. 6987, the device.

The present invention relates to an im--. p proved means for delivering air andpap; ticularly to the use of a pipe which" is? straight like the central drop. previous application but which, insteado being vertical, is placed at an angle to the vertical, preferably extending from a point near theside of the can at the top to a point near the center slightly above the bottom.

When the pipe is in this position, the air,

being delivered at an angle to the vertical,

as it loses its downward velocity, turns up-' .ward on one side of the outlet of the pipe, causing a swirl which is more effective in keeping the suspended matter in motion, and preventing it from becoming impounded in the ice, than is' the agiation produced by the more generally diffused air delivered from the vertical tube. In the latter instance, the air is' first projected directly downward from the end of the tube and rises upward on all sides with a greater tendency to diffusion than when delivered from the inclined pipe. Also, as the freezing progresses, the flow from the inclined pipe passes upward by a single direct channel and is more effective in keepingopen the path by means of which the air escapes to the surface than is the flow from the vertical pipe.

The invention relates to the use of a straight pipe which can be easily withdrawn from the frozen cake when heated, the pipe being placed at an angle to give the result I Specification of Letters Patent. Patented Nov. 30,1915.

stated andalso to means for supporting the pipe in this position. a

, The invention furtherrelates to a con-. venient means for connecting and disconnecting the air pipe and to a guide for the steam nozzle used in thawing out the delivery pipe prior to withdrawing it.

The drawings which form a part of this application show a can of the kind'used in the manufacture of can ice and in connection with this. there is illustrated an air delivery pipemounted in accordance with my invention. I also show details relating to the air connection and steam nozzle guide.

Figure 1 is a view showing partly in section and partly in elevation a clamp adapted to hold the air delivery pipe in the inclined position described; the figure also shows the air connection andno-zzle guide; Fig. 2 is a lan of the same; Fig. 3 is a vertical cenftral section through a can of the type used in the manufacture of can ice showing in elevation within the can an air delivery tube mounted in accordance with the principles of my invention, a bracket for supporting the tube, and, in a general way, the air connection and steam nozzle guide; and Fig. 4

shows a portion of the external air supply pipe with the removable portion of the air connection attached.

Referring to the drawings by numerals; the preferred form of the invention illustrated includesa straight delivery pipe 1 se at an angle to the vertical, means in the for of a bracket 2 for'supporting the pipe, a removable air pipe connection 3 carried by the supporting bracket at the top of the delivery pipe, and a steam nozzle guide 4, also carried bythe bracket.

As the air ispreferably delivered at the bottom of the cannear the center, and the delivery \pipe is inclined in order to direct the current of air in the manner host favorable to continuous and uniform agitation of the freezing liquid which prevents the suspended foreign matter from becoming impounded in the ice, the pipe is prefer- I the center of the can near the bottom.

ably extended from the top of the can at one side of the center to the center near the bottom and is conveniently supported on the top edge of the can by means of the bracket 2 which is a feature of this invention. This bracket is strengthened by webs as shown to give it the necessary rigidity. In the form shown, it includes a hook 6 which takes over the edge of the can and an arm 7 which projects into the can. This arm is apertured at 8 in a direction inclined to the vertical, the aperture being preferably directed toward This aperture has a threaded portion 9 near the bottom to engage a correspondingly threaded end 10 of the delivery pipe, and below the thread at 11, the aperture is preferably smooth and of a diameter to fit the outside of the pipe and serve as a guide and support for the pipe. Above the! threaded portion, the aperture is enlarged forming a shoulder 12 and a chamber 13 in which is a rubber sleeve or tube section 11 which should be of pure rubber gum to resist the action of heat and steam used in removing the delivery tube from the cake of ice. This rubber sleeve or ring ll forms an adjustable gripping member to engage the metal tip 15 which is secured to the flexible air supply pipe 16, of which there is one to each can, the supply pipes being connected to the compressed air mains in accordance with the description of the previous application referred to herein. To vary the intensity ofthe grip, a nut or screw plug 17 is provided which engages an internal thread 18 in the apertured portion of the bracket. This plug has a central hole or opening 19 to admit the tip 15 of the supply pipe. To increase the intensity of the grip, the plug 17 is screwed down against the rubber ringcompressing it and reducing the size of the central opening 20 in the ring or sleeve. For the purpose of making the engagement effective, the tip 15 is crowned or enlarged at its lower end at 21 so as to offer increased resistance to the withdrawal from the socket or gripping member 14, and the butt is made to fit the tube having circumferential grooves or barbs to improve the engagement.

Another important feature of the device is found in the positioning or guiding surface 22 which serves as a means for locatrng the steam nozzle or needle. When freezing is completed and it becomes desirable to remove the delivery pipe from the cake of ice, steam is injected into it to raise the temperature of the pipe and thaw the immediately surrounding ice and release the pipe. This cannot be done conveniently by admitting steam to the top end of the air pipe. In order to accomplish the desired result, the steam must be delivered to the bottom of the air pipe and to this end, a steam needle or elongated nozzle is used which is substantially the length. of the air pipe from the bracket to the bottom end. This steam noz zle is thrust into the delivery pipe after the air supply pipe 16 has been disconnected, and on account of the length of the nozzle, considerable difliculty is experienced in inserting it. To form a suitable guidefor this nozzle, the nut. 17 has been cupped as described, at 22, forming an external guide surface or conical concavity, the axis of the cone being concentric with that of the air pipe.

The advantages of the invention are found, first, in the fact that the air thus delivered from the inclined pipe produces more thorough agitation and thus keeps the foreign matter in suspension to better advantage than when the air is moregenerally diffusedas by a vertical pipe; that after freezing has taken place, choking of the air passage is less apt to occur on account of the fact that the current of air, instead of being diffused, is directed into a single channel. Placing the pipe in this way also has the advantage that it leaves the center of the can near the topunobstructed so that when water having'a high content of foreign matter is used, the core may be pumped out near the end of the freezing process, removing all the impurities and the inclined pipe oflers no obstruction to this operation. The

pipe placed in this position has the advantage over an outside pipe or one placed in the corner of the can, that it is not subject to the lowest temperatures until the freezing process is well advanced so that condensation of moisture with consequent choking of the pipe is less apt to occur. Freezing takes place first at the sides well below the top, and more rapidly at the sides than at. the bottom where the circulation of brine is not active, so that the pipe is not subject to a temperature below 32 until freezing has been in progress for a considerable period, and even then, the temperature of the ice which comes in contact with the pipe is not as low as that of the brine to which the outside pipes or those placed directly against the walls of the can are subject. Another advantage of this construction is that the connection is near the header and also the length of hose required is shorter and therefore cheaper and easier to handle.

By means of the removable connection which I have described, the intensity of the grip taken by the stationary member upon the removable tips of the supply pipe, may be varied at will as the rubber wears, so that the life of the partsis ahnost interminable, and, in addition to this} the connections may be made with the shortest possible delay. WVhen freezing is completed, the air pipes are withdrawn instantly and the steam nozzle inserted by way of the guide 22 without appreciable difiiculty, and the operation is accomplished instantaneously in the case of eachcan.

The improvement relates to the perfection of the product as well as to efliciency and economy of operation.

Having thus described my invention, what I claim and desire to secure by Letters Patent 1s:
