'I0 convenient and efficient use.

A further purpose is to provide tap con nection into the usual commercial pipe lateral or header that will not work loose and leak in service.

A further purpose is to avoid dirt and scale from the lateral, which frequently clogs throttling oriiices or contaminates the ice, by tappiner at right angles to the iiow and from the middle of the lateral.

A further purpose is to place the throttling orifice where it is accessible for cleaning and inspection, at the plug member of a plug and socket coupling between the air tube in the can and a flexible connection to the air header or air lateral.

A further purpose is to provide a bank or group of connected air cans, handled as a unit, with automatic valve mechanism for turning on the air as the unit is connected up.

A further purpose is to fit the terminal of a flexible air pipe for connection with air pipes of* different diameters.

A further purpose is to provide an offset terminal for connection with the air pipe to keep the connections out of the line of movement of the ice during the discharge oi the ice from the can.

Further purposes will appear in the specification and claims.

Describing in illustration and not in limitation and referring to the drawingsz I take up first the invention as used in the layout of Figures 1, 2 and 3.

The air lateral 15 is tapped with T connection 16 and supplies diagonally opposite cans 17 with introduction of agitating air through flexible hose connections 18,` plug and socket couplings 19 and air tubes 20,

loosely carried by brackets 21 from the sides of the ice cans 17.

To keep dirt and scale from entering the tap, I extend the tap shank 22 to approximately the middle of the lateral, where the air velocity is a maximum and the quantity of dirt and scale carried by the air is a minimum. Such dirt and scale as is present at the middle of the lateral is too heavy and its velocity is too high for it to Vturn at the abrupt angle requisite for entering the tap along with the relatively very light air. As a result the air enters the tap substantially free from dirt and scale.

I place a ring 23 of lead or other sufficiently plastic metal between the shoulder 2a of the tap fitting 16 and the lateral 15, to prevent the tap connection from working loose and leakingin service. I have used aluminum also for this purpose.

The T is intended to be set in alignment with the lateral and the compressibility of the ring permits additional tightening of the T, if necessary to secure this alignment, 28

after the concave side 25 of the ring has been forced against the pipe by pressure ofthe T shoulder against the fiat side of the ring.

The soft metal ring support around the shank of the T 16 gives the fittingadequate Vsupport and tightness and permits a tightening of the T not only in alignment with the pipe but, if this be not desired, at any angular position with respect to the lateral.

The throttling orifice 27 between the lateral and the air tube F20 is located upon the plug,` 'member 28 of the plug and socket Vcoupling 19, giving very easy access to it for cleaning.

VrIhe projection of the end 19 about the orifice protects from clogging by any small amount of dirt or scale and when there is enough accumulation in the pocket 29 formed to interfere with air passage the parts are readily disconnected and cleaned.

The socket member 80 of this couplingis fiar-ed to -guide the plug or a thawing needle and is drained at 81 to prevent ice from forming at this point. i' Q Y In the layout of Figures 4t to 7, during the freezing operation the air tubes 2O hang'from a transverse lateral lwhich is temporarily placed across the tops Ofa'number of cans, 'being lfed in anysuitable manner from a header or other supply not shown. Y

The air tubes are separately `connected by plug and socket coupling 19 to the flexible hose connections 82 carried by the tap fittings 16l which are tapped. into the header. Asbefore the shankof the fitting is made to extend substantially to the middle of the air-supply pipe, thus avoiding the entrance into the tube of dirt and scale with the air. As before the soft metal ring support 23 may be compressed between they air supply pipe and the shoulder of the tap, thus strengthenving the tap connection so that it may not gradually work loose and leak in Service.

In all of these forms the T is given full opening from the lateral or header.

In Figure 7 I havewshown the throttling orifice 23 placed at the entrance to the tap fitting to illustrate the advantage of the soft metal ring and inlet near the axis of the lateral even where the full advantage of my invention is not obtained by locating the throttling opening at the end of the flexible connection farthest from the lateral or header. f The drop tube could be directly connected to the flexible tube without terminal In the layout of Figures 8 and 9 the arrangement is substantially the same as in Figures 1 and 2 with the exception that the air tube is permanently fastened in onecorner of the can instead of removablydepending along the can axis from a bracket.

I f special measures have been taken to eliminate moisture from the air supply before it reaches the laterals, this arrangement is preferable in that the tube is vmore out of the way and does not have to be handled, but unlessV such special and` relatively costly measures have been taken I prefer placing the tube near the can axis,l where ice forms last and the tube is jacketed with water until the freezing operation is practically coinplete. As long as the tube is jacketed with water instead of ice the interior of the tube remains free from accumulating ice and snow precipitated from the moisture in the-incoming air, that rapidly collects if such spe- T- cial measures 'have not been taken to eliminate the moisture in the air before it reaches the tube'.

In raw water ice systems where dehydrated air is used Aand where the air pipe within the can is against the side of the can, the desirability of having the water in the can initially as low in temperature aspossible makes it freeze very rapidly after the can is submerged, giving butlittle time for connection of the lateral to the air pipe. Sometimes before the terminal upon the flexible air con-y nection is insertedwithin the air pipe the air pipe itself has frozen up preventing aeration of the can through that pipe. Under these conditions it is very desirable to substitute another air pipe which may be put down within the unfrozen part of the can to save this can of ice from becoming opaque.

However, the terminal inlets for air pipes intended to be separately supported in the can are usually larger than for those attached to the side of the can for the reason that the separately supported tubes must acco1nmodate a thawing needle.

It the operator has delayed making the connection to the side of the pipe and has found it frozen up he can quickly and easily attach the same terminal to a drop tube. such as may, tor example, be carried by a bracket, by means of the terminal shown in Figure 10 in which I show two diameters ot terminal 19 and 192, intended to tit the two sides ot air pipes respectively. The smaller diameter of terminal 19 tits the side tube and the larger diameter 192 lits the separate tube.

There a group or set ot cans is rigidly held together within a basket, crate or trame 33, so as to make it possible to handle the entire group or set as a unit, I provide for automatic opening ot the air valve with connection of each set by an automatic valve ot which a very desirable form is shown at 34. This automatic valve is held open in use for ilow of air from the header to the lateral, but when the lateral is disconnected from the header stops flow of air from the header protecting the header against air leakage. As shown the valve comprises male and temale parts 35 and 36 of which the latter is secured at the lett of Figure 12 in a header 37. A male or operating valve member is mounted upon a flexible pipe 38 secured to a lateral 39 which may be clamped by bracket 40 and hook bolt l1 against the side of the frame work or can.

The female valve member carries a valve seat 42 closed by a valve 43 mounted upon a stem 44, terminating in a cross bar 45. This bar extends within an enlarged mouth 46 tapered to receive the tapered end 47 ot the male member. The parts are proportioned so that the terminal 47 becomes air tight when the bar has been shoved by the end 48 of this terminal far enough to properly open the valve. The valve is automatically closed by the How of air when the parts are disconnected.

A similar automatic valve member is secured to the opposite end of the lateral so that each lateral carries a valve member at one end and an operating member at the other. As a result a series of sets or blocks can be connected, one to the other, each connection automatically supplying air and each disconnection cutt-ing oli' the air.

Y As the cakes ot ice are discharged trom the cans without disconnection of the lateral, I bend in two or more planes the terminal 193 by which the air taps 49 are connected through flexible pipes 18 with the corner air pipes 20. This enables me to keep the flexible pipes out of the path of ice discharge. The air pipes here are intended to be rigid with the sides of the cans but by the use ot two different tube diameters for connection at 19, if the pipe 20 becomes frozen up connection can be made with a separate pipe dropped into the can just outside of the frozen part in some such position as shown by the circle 50.

For convenience in making connections be tween the parts et' the automatic valve I mount a handle upon the operating member of the valve at the end ot its flexible connection, this handle being shown generically at 51. i

I appreciate that others skilled in the art, in view ot' my invention and disclosure, may see modiiications and variations to meet individual whim or particular need and it is my purpose to cover herein all such varia tions and modifications in. so tar as they tall within the reasonable spirit and scope of my invention.
