Abstract
Abstract Apparatus including a rotary upright spindle is placed within a chamber confined by an openable mantle casing in order to extract water or watery liquid from textile pirns mounted thereon by centrifugal effect caused by a high speed axial rotation thereof, subsequent rotation of the spindle at relatively lower speed in combination with a supply pump and a cross valve causing circulation of oiling agent through the textile pirns.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
146 words
An improved apparatus for centrifugal hydroextraction combined with oiling of textile pirns comprising, in combination, a stationary and openable hollow casing defining a chamber; an upright cylindrical spindle disposed, for axial rotation, within said chamber and provided with numerous radial perforations formed through the shell thereof; an upper carrier assembly mounted to the top of said casing and clamping the upper end part of said spindle; a lower carrier assembly disposed to the bottom of said casing and bearing said spindle for said axial rotation; means for mounting pirns on said spindle in a superimposed disposition; means for causing said axial rotation of said spindle and connected to said lower carrier assembly; means for discharging water or watery liquid off from said chamber; and means for compulsorily circulating oil through the interior of said spindle, said perforations of said spindle, said chamber and said discharging means.
Claim 2
Dependent Claim
146 words
An improved apparatus for centrifugal hydroextraction combined with oiling of textile pirns comprising, in combination, a stationary and openable hollow casing defining a chamber; an upright cylindrical spindle disposed, for axial rotation, within said chamber and provided with numerous radial perforations formed through the shell thereof; an upper carrier assembly mounted to the top of said casing and clamping the upper end part of said spindle; a lower carrier assembly disposed to the bottom of said casing and bearing said spindle for said axial rotation; means for mounting pirns on said spindle in a superimposed disposition; means for causing said axial rotation of said spindle and connected to said lower carrier assembly; means for discharging water or watery liquid off from said chamber; and means for compulsorily circulating oil through the interior of said spindle, said perforations of said spindle, said chamber and said discharging means.
Claim 3
Dependent Claim
99 words
An improved apparatus as claimed in claim 1 wherein said upper carrier assembly includes, in combination, a bracket fixed to a stationary part of the framework of the apparatus, one or more contact rolls pivoted to said bracket in an arrangement peripherally contactable with said spindle upper end part, a swingable arm pivoted to said stationary framework part at its one end and pivotally carrying at least one contact roll peripherally contactable with said spindle upper end part and means for locking said swingable arm to a position wherein said contact rolls cooperatively clamp said spindle upper end part.
Claim 4
Dependent Claim
46 words
An improved apparatus as claimed in claim 2 wherein said locking means includes a locker bar extending across said swingable arm and vertically turnable about a fixed pivot on its end and said locker bar restricts free swinging of said swingable arm in its lowered disposition.
Claim 5
Dependent Claim
64 words
An improved apparatus as claimed in claim 1 wherein said spindle is provided with a disc fixed to the bottom thereof, said lower carrier assembly includes a flange rotated by said rotation causing means and having a central hollow receptive of said bottom disc of said spindle and said disc is firmly joined with said flange bY a means for wedging the two elements.
Claim 6
Dependent Claim
57 words
An improved apparatus as claimed in claim 4 wherein said wedging means includes one or more radial projections formed on the periphery of said disc and a corresponding number of L-shaped members disposed to cut-outs formed radially through the annular wall confining the central hollow of said flange, said L-shaped members slightly protruding into said central hollow.
Claim 7
Dependent Claim
25 words
An improved apparatus as claimed in claim 4 wherein the bottom of said central hollow of said flange is partly covered by an elastic surface.
Claim 8
Dependent Claim
45 words
An improved apparatus as claimed in claim 1 wherein said pirn mounting means includes a pair of vertically spaced holder plates, the upper one being removably inserted over said spindle in a vertically adjustable arrangement and the lower one being fixedly inserted over said spindle.
Claim 9
Dependent Claim
45 words
An improved apparatus as claimed in claim 1 wherein said rotation causing means includes a drive motor, a driven pulley integral with a rotary part of said lower carrier assembly and a belt or the like for connecting said drive motor with said driven pulley.
Claim 10
Dependent Claim
18 words
An improved apparatus as claimed in claim 8 wherein said drive motor is of a speed variable type.
Claim 11
Dependent Claim
18 words
An improved apparatus as claimed in claim 8 wherein said drive motor is of a speed shiftable type.
Claim 12
Dependent Claim
32 words
An improved apparatus as claimed in claim 1 wherein said discharging means includes a discharge pipe opening at the bottom of said chamber and a drain pipe connected to this discharge pipe.
Claim 13
Dependent Claim
78 words
An improved apparatus as claimed in claim 1 wherein said compulsory oil circulating means includes an oil bath, a pipe leading from this oil bath to a conduit formed through said rotation causing means and lower carrier assembly opening into the interior of said spindle, a supply pump disposed to this pipe and a cross valve disposed to said discharging means and introducing the oiling water discharged from said chamber into said oil bath during the oiling process.
Claim 14
Dependent Claim
21 words
An improved apparatus as claimed in claim 12 further comprising means for sealing the junction of said pipe with said conduit.
