Description

July l1, 1950 R. E. GOLDSBROUGH EMULSIFYING MACHINE Filed June 25, 1947 I INVENTBR;
M MMV/ Patented July l1, `1950 j UNITED EMULSIFYING MACHINE Robert Edwin Goldsbrough, Putney, London,
' England Application inneres, 1947, serial No. 756,953 In Great Britain September 26, 1945 section 1, Public Law 690, Augusta, 1946 Patent expires September 26, 1965 This invention consists in an emulsifyingmachine containing in one unit a mixing device, a homogenizing device, a filling device,` a mechanism for creating vacuum and another mechanism distinct from the first for breaking the vacuum, both said mechanisms being arranged between the mixing and the homogenizing device.
A lever or the like having an air passage connected with the atmosphere may be used as the second mechanism `and arranged between the mixing device and the homogenizing device and adapted to break the vacuum produced between the two devices, so as to prevent the emulsion being drawn out of the mixing tank.
The homogenizing device may be adapted to work under variable pressure.
The mechanism for creating a vacuum between the mixing device and the homogenizing device may be adapted to be used for the injection of air into the mixing apparatus.
The homogenizing device may be provided on its outer periphery with minute slots parallel to its axis, through which the mixture to be homogenized is caused to pass.
The motor drive for creating the vacuum may be used for actuating a paddle or the like inside the mixing device.
The accompanying drawing shows by way of example one mode of carrying the invention into effect.
Referring to the drawings, with any suitable rotary drive a variable stroke is produced to two horizontally opposed pistons B and F by means of a link operated by an adjustable roller xed to a flywheel D. One piston o-perates in a cylinder A surmounted by a mixing tank U. The mixing tank U is fitted with an automatic foot valve N which allows the piston to draw a predetermined -amount of emulsion into the cylinder A. The cylinder A is also supplied with an air valve V which may be opened to allow the piston to move Without drawing in any emulsion.
The machine proper is mounted upon a pedestal which encloses the motor coupled to a shaft H, the lower end of which holds a worm gear E which in turn is coupled to the variable link drive D.
One end of the piston B has a hydraulic seal C, operating in the cylinder A. The other end F has a leather washer operating in a cylinder and acting as an air pump with an outlet G. The
outlet may be coupled to areciprocating paddle which is not shown. This .paddle may be used to 'produce turbulence in the emulsied mixture.
y The other end of the shaft 'H drives the bevel gearing in the gear box J through which projects the propeller shaft K terminating in the propellers lVL The shaft K may be iixed at any level by the locking handle L which operates upon a split cone extensio-n of the second bevel gear.
The end of the cylinder A has mounted upon it the container U which is supplied with a foot valve N. At the opposite end is the homogeniser unit P which is held up against the cylinder casting by a spring Q which can be varied in tension by means of washers or an adjustable screw. At the lower extension a lling spout is held in position by a nut. The upper end of the homogenising unit P and the cylinder casting are machined at an angle of degrees making a tight t. Also upon the homogenising unit periphery there are ne parallel slots S machined. Behind this is annular space having small holes W connecting with the hollow centre of the unit P. Behind the valve face, a space X is provided in order to allow the mixture to expand before passing through the slots S.
Finally, the end of the casting A is supplied with a boss into which is screwed the operating lever O. This lever has a hollow centre with two holes drilled diametrically across the centre so that when the lever is opened, a valve V allows the air to pass through the lever holes into the cylinder and thus break vacuum.
The hydraulic seal C is composed of the usual synthetic rubber cut washers screwed together in compression in order to provide a pressuretight piston. This will prevent leakage of the emulsion into the gearbox and oil from the latter into the emulsion.
Method of operation-The various ingredients of the emulsion are put in the container U at a temperature of about '70 C. The lever O is then opened and the electric current is switched on. The shaft I-I immediately turns and the piston B commences to oscillate. The gears drive the propeller shaft K and intimate mixture of the emulsions is maintained. As the operating lever O is in the open position the pistons merely idle but when the temperature of the emulsion has dropped to 40 C. the operating lever O is closed tightly and a vacuum is produced inside the cylinder A. This opens the foot valve N and the emulsion is drawn in by the exhaust stroke and it is compressed by the return stroke. The emulsion can only escape by forcing back the unit P where it is given the first stage of ho-mogenisation between the valve faces. It then expands into the annular space behind the valve face and it is then forced through the fine slots S to expand again and pass through the small holes W into the filling; spoutwhere the mixtures i's1-bott1e:dor packed into-jars in acompletehomogeni'sed` and stable condition.
From the foregoing it will be understood than?.
with one machine and one motor drivathefwhole of the operations of the emulsication, homo;-
genisation and filling into jars-zy or'A bottles, are;l
complete in a quick and perfect manner.
What I claim is:
1. An emulsifying machine containing-in; Quei unit a mixing device, a delivery device for the:
ity, a piston for varying the capacity-creamV cyl'- inder, a slidable unit operating as a nonereturn valve and also as a device for providing two stages of, homogenisatiom thek rst. stage comprising twoconical facesfheld together byl a strongghelicoidaispring for the forcing ofk the Vproductirom the mixing device underv` pressurel therethrough means. of the` said. pistonwhen moving` to refduce,..the, capacity off,- sai'dcylnder,N and the sec,-
,Y position, provides a passage to the atmosphere betweenthe mixing device and the homogenizing dievicein ordertoy prevent the mixture from being drawn from the mixing device until the lever is replacecLin its l.closing position.
