COMPRESSOR FOR ICE-MACHINES.
Speccaton of Letters Patent.
Patented Julyl 1 7, 1 906.
Application tiled May l, 1905. Serial Nol 258,198.
To all whom t may concern..-
Be it known that I, CASPER W. MILES, a citizen ofthe United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Compressors for Ice- Machines, of which the following is a specification.
My invention relates to improvements in ice-machines. One of its objects is to provide an ice-machine compressor with improved cooling mechanism, whereby it may be readily removed from the compressor to give access thereto or replaced if damaged by freezing of water therein or otherwise.
Another object is to rovide improved means for lubricating t e compressor or plunger. 1
Another object is to provide an improved form of plunger.
Another object is to provide improved intake and exit valve mechanism.
It further consists in certain details of form, combination, and arrangement, all of which will be more fully set forth in the description of the accompanying drawings, in which- Figure l is a side elevation of my improved compressor. Fig. 2 is an enlarged vertical section on line v o of Fig. l. Fig. 3 is a bottom plan view of the exit-valve cage. Fig. 4 is a section on line :1; of Fig. 2.
Arepresents the base A', the main drivingshaft, which may be driven by a belt-pulley a or, if desired, by a crank and pitman in place thereof.
a represents the ily-wheel.
B represents the compressor-frames; B, the compressor-cylinders; C, the plungers; C', the crank-wheelson the main shaft, and c the connecting-rods connecting the crankpins c of the crank-wheels to the wrist-pins d of the plungers to drive the plungers. The frames B have heads b b at opposite sides, so that access to the interior may be readily had. The main shaft journals in boxes d in the heads b, which boxes are packed to prevent the escape of the refrigerant. The cool refrigerant enters the compressor through pipes e and after being compressed escapes from the compressor through pipes e.
The chambers B, inclosing the crank-wheels and also the lower part of the cylinders, are kept cool by the cool refrigerant. The upper ends of the cylinders are cooled by water circulated through the jacket D, entering throu h pipes E and escaping through pipes E. he jacket is composed of a cylindrical section f and cap f and is supported upon a flange F, formed integral with the cylinder. The exit-pipe e passes through the cap, and a stuffing-box g prevents the escape of water at this point, while a cap g locks the gland G in place and prevents it working loose from the vibration of the machine. Thus either one or both sections of the jacket may be readily removed and access to the cylinder obtained. The jacket parts are of simple form, readily cast and machined.
The plunger is formed of a cap h and cylindrical section h, secured together by screws t'.
H represents the intake-valve, which is mounted in a cage H and held to its seat by a spring t engaging a collar j on the valvestem. The cage H is screwed into the cap h and has a flange J, which is clamped between the cap h and cylinder. h to lock the cage in place, which is important, as the continual vibration tends to loosen the screw-joint. One acking-ring s is seated in a groove in the cap and one or more rings s in grooves in the cylinder h The inner Walls of the compressor-cylinder are highly heated by the compressed gas, and in order that the plunger and cylinder-walls may be thoroughly lubricated I provide an annular groove K near the lower edge of the plunger adapted to retain oil therein. I also provide grooves or cups K on the inside of the plunger, which are referably cored therein and which catch suc i oil as may be thrown by the revolution of the crank-wheel and connecting-rod and conduct the same through holes lc to the exterior of the plunger, where it is allowed to work down along the cylinderwall to the groove K. A spiral groove k is also preferably formed in the face of the plunger below the packing-rings to distribute the oil evenly over the cylinder-surface. A quantity of oil S is stored in the lower part of the chamber B, into which the crank-pin, crankwheel, and lower end of the connecting-rod dip, which in a small rapidly-driven comressor serves to throw suicient oil into the inside of the plunger to lubricate the parts. In large slow-running compressors I provide on the crankin a horn L, which dips mouth downward into the oil at each revolution and forces a small quantity of oil past the checkvalve L into the assaoe Zin the connectingrod and thence t nougIr passages 1" in the pin d to the cups K', whence it flows to the face IOO IIC
of the cylinder, and any excess is free to overi'low from the upper to the lower cups K. (See Fig. 2.)
M represents the cylinder-head, to which is screwed the cagev M of the exit-valve m. This valve is forced from its seat at each stroke of the plunger and requires to be carefully controlled to prevent accident and injury thereto.
N represents lugs or fingers projecting from the cage and agalnst the ends of which the upper ace of the valve strikes to limit its motion to prevent undue strain on the valvespring m and to prevent any tendency of the valve to lift more on one side than the other, which would strain the stem-bearing. A shoulder n is also provided on the stem to assist in limiting the valve movement.
R represents the valve-seat locked in place by the cage M.
Over the-cage M and head M is a cap P, which clam s a flange p of the cage between itself and tllie head, and thus locks the cage securely in place and prevents its screw-joint becoming loose. At the top of the ca p the exit-pipe e is attached by a threaded joint.
I am thus enabled to rovide a simple, inexpensive, efficient, an thoroughly reliable compressor which may be placed in inexperienced hands for use.
The mechanism herein specified is capable of considerable modification without departing from the principle of my invention.
Having described my invention, what I claim is- 1. In an ice-machine compressor havin a jacketed vertical cylinder, and an inlet-va ve in the plunger so that the cool gas enters through the plunger and escapes at the upper end of the cylinder, an oil-receptacle on the interior face of the plunger, an annular oil-receptacle at the lower end of the outer face of the plunger, said interior oil-receptacle being at greater elevation than the exterior oil-receptacle, and a passage through the plungerwall connecting said oil-receptacles.
2. In an ice-machine compressor having an inlet-valve in the lunger so that the cool gas enters through t e lunger and escapes at the opposite end of t e cylinder, one or more oil-receptacles on th interior face of the plunger, an annular oil-receptacle at the lower end of the outer face of the plunger, said interior oil-receptacles being at greater elevation than the exterior oil-receptacle, and pas- 5 5 sages through the plunger-walls connecting said oil-receptacles.
. 3. In an ice-machine compressor having a vertical cylinder, a gas-receiving chamber forming a housing for the crank and connect 6o in -rod and a plunger provided with a gasinet valve and passages to lead the gas vfrom said chamber tothe cylinder; an annular oilcup at the low'er end of the outer face of said plunger, a series of oil-cu sin the upper portion of the inner face of t e plunger, and passages leading from said last-named cups to the outer face of the 4said plunger above said annular cup.
4. In an ice-machine compressor, a plun- 7o ger having an oil-cup at the lower end of the outer face, an oil-cup in the inner face of the plunger above said first-named oil-cup, a passage leading from said upper oil-cup to the outer face of the plunger, and means substan- 7 5 tially as specified for lntroducing oil into the upper oil-cup.
5. In an ice-machine compressor, a plunger having an oil-cup formed in the 'upper ortion of the inner face thereof, a passage 8o eading therefrom to the outer face of the plunger, a spiral groove leading from said passage around the exterior of the plunger, and means substantially as specified for supplying oil to said cup.
6. n an ice-machine compressor, a plunger .having an oil-cup formed in the upper portion of the inner face thereof, a passage eading therefrom to the outer` face of the plunger a crank-pin, a horn carried thereby adapted to dip mouth forward into an oil-reservoir, a passage from said crank-pin through the connection-rod to said oil-cup, and a check-valve controlling the flow of oil from the horn to the oil-cup.
In testimony whereof I have aiiixedvmy signature in presence of two Witnesses.
