ICE-MAKING MACHINE.
To all whom it may concern:
city and county of San Francisco and State of California, have invented new and useful Improvements in Ice-Making .Machines, of which the following is a specification.
This invention relates to an ice making machine. I I i j All of the clear, pure ice manufactured b0. day for household uses and the like is made from condensed steam. Clear ice isalso propressed air which is forced through. a pipe submerged in the water. At present this is partly accomplished but islimited by the fact that the tube delivering the air below the water surface must be withdrawn before solidification is complete, leaving a cloudy core from the water solidified after agitation has ceased.
It is one of the objects of the presentinvention to provide a simple attachment whereby the pipe will be automatically withdrawn as the ice forms, or, in other words, to continue agitation within the receptacle until solidification has been completed.
Another object of the invention is to provide a pneumatically actuated mechanism whereby the air will be distributed: and the pipe automatically lifted.
Further objects w ll hereinafter appear. The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a central, longitudinal section throughthe machine or apparatus. Fig. 2 is a plan view of same. Fig. 3 is a cross section on line 38, Fig. 2.
, More specifically described, A indicates an ordinary freezing tank filled with brine, or like solution, which is kept at a freezing tem-' perature by means of ammonia pipes, orthe like, in the usual manner. Mounted in tank A and filled with the water to be frozen is a tank B, and extending down into said tank is a pipe 2 through which the air is delivered. Pipe 2 is mounted in a .guide bracket 3 and is adapted to be slowing re- .ci-procated by means of a clutch 4:; carried in Specification of Letters Patent.
' 10, which is constructed lows: I 1 1 and 12 indicate apair of convex shaped casings which are clamped together by l i i the outer end of anarm v5, centrally pivoted,- Be it known that I, JOHN; Munrnv, a citizen of the United States, residing in'the as at 6, on a standard T. The other end of rod'9 of an ,air motor generally indicatedfat and operated as folmeans ofbolts or screws 13. Interposedbe tween said caslngsections is a flexible diaphragm 14, and secured to said diaphragm, by means of plates 15, isthe piston rod 9.
.Air isalternately admitted and exhausted oneach side of the diaphragm 15 by means atented Nov. 16, 915.
Appfieation filed septem ber 28, 1914. Serial No. 863,867.
of a three-way valve16. Air under pressure is admitted to the lower side of the valve, at
17, by a pipe 18 and is from here directed by a port 19, formed in 'theplug 20, to one or the other ofa pair of pipes 21 and 22,
pipe 21 being-connected with the uppercasmg 11 while the lower pipe 22 is connectedto the lower casing 12. Live air admitted'at 17 and passing through the port 19 will pass out through the pipe 21 and into the upper casing .11. This will force the diaphragm downwardly and will at the same time permit the air in the lower side of the casingto exhaust through the pipe 22. This forces the piston rod 9 in a downward direction, transmitting a rockingmovement to arm 5.
Mounted on arm 5 is a pin 23 which is adapted to engage with a quick acting valve lever 24. .This lever is connected by means of a link 25 with a lever 26 secured to the valve plug. A slight contact of the pin 23 with the'lever 24: will move this into a positionwhere a spring 2'? connected therewith will turn it quickly from one side of the center -6 to the other. This quick throw of movement of the lever from one side of center 6 ;to the other will be transmitted, through the link 25 and arm 26, to throw the valve plug in thedirection of arrow 0; where port 19 will be moved out of register with the connection 17 and into register with an exhaust port 28. A cutaway portion 29 on the valve will then form communication between pipe 21 and the exhaust connection 28. Aport 19 will, at the same time, be thrown into register with the connection 17 and will permit the ,air under pressure to pass through the pipe 22 into the lower side of.
ward direction. The air previously ade- "mitted through pipe 21', on the upper side of the casing,-will then be permitted to exnioveme'nt of the flexible diaphragm, caused by thead nission of airinto the lower side 7 e r of thecasing through pipe 22, will similarly transmit movement through the piston ,rod 9 to move arm 5 in an upward direction. The
pin'23'will now" engage withanupper shoulder formed on the quick acting valve lever i 24. and will move it'into a position where the spring27 will throw it into theop'posite direction, moving the plug in a direction op posite to that indicated by arrow at. Port 19 will now be thrown into exhaust posltion,
while port 19 is moved into intake position.
The operation of thefiexible diaphragm,
with, connected valve mechanism, is thus 'continuous and automatic and the reciprocal movement is transmitted to'pipe 2. The
air used in connection'with the flexible diaphragm, when exhausted byvalve 16, is con- V 'eveyed through the ,fle'xible hose 31 to the reciprocal pipe 2. All-the air is thus used and not wasted. Part of the airunder pressure maybe passed directly through the hose 3 1, ifzthe exhaust air from the diaphragm does notprove to be suflicient. 'This is accomplished by placing a valve 32 in an intermediate position between pipes 30 and '18. Air under pressuremay thusbe passed directly from pipe 18, through valve 32 and pipe 30, into the flexible hose 31, with connected pipe 2. The speed of reciprocation or movement of the diaphragm may also be controlled by valve 32, as the adjustment of same will cause more or less air topass 'directly to the pipe Without passing through thecasing anddiaphragm. 'The exhaust from pipe 22, passing through the by-pass 29, is exhausted through a pipe 33 which is'in turn connected with pipe 30 and the flexible hose connection 31. a p
Inoperation, the moment the water within tank Bbecomes partly frozen it will be seen that the reciprocal movement of pipe 2 will intime bring it into contact with the bottom ice. The clutch 4 will then slide down on-the pipe and permit the pipe to rest on the ice. The upwardimovement of arm 5 and clutch 4 will again pick up the pipe and keep it reciprocating until it again strikes the'ice as it is gradually formed. The pipe is thus automatically and gradually withdrawn as the ice forms and agitation of the 'water subjected to the freezing temperature is continued until the contents, has become completely solidified. r
The present device eliminates a steam pro-' ducing plant, condensers, cooling system's,
alarge plant.
