Abstract
Abstract A device for raising and centering 45 r.p.m. records on a standard turntable having a central spindle. The device fits around the spindle and completely fills the large hole of 45 r.p.m. records. Four radially outwardly extending lifting arms project through corresponding slots made in the cylindrical housing of the device. A vertically displacable circular cap is mounted at the upper portion of the housing and is adapted for manual depression. The internal construction of the cap and housing is arranged to raise the arms and a record lying thereon by lever action when the cap is depressed against the inner portions of the arms.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
A device for removing and centering at least one 45 r.p.m. record on a standard turntable having a central spindle, comprising: a cylindrical housing having a bottom surface and an open top; said bottom surface having a central hole for precisely receiving said spindle; the external diameter of said housing being slightly less than the diameter of the large central hole of said record; said housing further having at least two equi-spaced, rectangular vertically oriented slots formed in its side wall wherein the lower edges of said slots are flush with said bottom surface; at least two elongated arms extending through said slots; each said arm having an outer straight radially projecting portion and an inner portion terminating radially short of the center of said housing; an intermediate segment joined to both said outer and said inner portions; fulcrum means between said intermediate segment and said inner portion; the latter being vertically spaced relative to said outer portion; further comprising a circular cap slidably mounted in said housing for vertical displacement therein; biasing,displaccment limiting and guide means for said cap; the inner ends of said inner portions of said arms being arranged to raise said outer portions of said arms upwardly by lever action when said cap is pressed manually downwardly.
Claim 2
Independent Claim
211 words
A device for removing and centering at least one 45 r.p.m. record on a standard turntable having a central spindle, comprising: a cylindrical housing having a bottom surface and an open top; said bottom surface having a central hole for precisely receiving said spindle; the external diameter of said housing being slightly less than the diameter of the large central hole of said record; said housing further having at least two equi-spaced, rectangular vertically oriented slots formed in its side wall wherein the lower edges of said slots are flush with said bottom surface; at least two elongated arms extending through said slots; each said arm having an outer straight radially projecting portion and an inner portion terminating radially short of the center of said housing; an intermediate segment joined to both said outer and said inner portions; fulcrum means between said intermediate segment and said inner portion; the latter being vertically spaced relative to said outer portion; further comprising a circular cap slidably mounted in said housing for vertical displacement therein; biasing,displaccment limiting and guide means for said cap; the inner ends of said inner portions of said arms being arranged to raise said outer portions of said arms upwardly by lever action when said cap is pressed manually downwardly.
Claim 3
Dependent Claim
22 words
The device of claim 1, wherein there are four equispaced slots, four corresponding arms and said cap is of a frusto-conical shape.
Claim 4
Dependent Claim
66 words
The device of claim 2, wherein said intermediate segment extends upwardly at a right angle to said outer portion and has a loop at its upper end joined to said inner portion, whereby the latter is upwardly spaced from said outer portion; said fulcrum means consisting of a tangential pivot pin engaged under ssid loop and located adjacent the upper edge of its associated said slot.
Claim 5
Dependent Claim
52 words
The device of claim 3, wherein said cap is provided with four vertical elongated tabs fixed to the upper portion of the cap and projecting downwardly therefrom, being vertically aligned with said inner ends of said inner portions and adapted to push downwardly on said inner ends when said cap is depressed.
Claim 6
Dependent Claim
32 words
The device of claim 1, wherein said biasing means consists of a compression spring abutting said bottom surface around said spindle and abutting the underside of the top surface of said cap.
Claim 7
Dependent Claim
23 words
The device of claim 2, wherein said limiting means includes a circular upwardly, inwardly inclined lip at said open top of said housing.
Claim 8
Dependent Claim
54 words
The device of claim 2, wherein said guide means consists of a pair of vertical guide pins fixed to the upper portion of said cap at their upper ends; each said guide pin being adapted for reciprocal sliding movement in a correspondingly aligned guide cylinder secured at its lower end to said bottom surface.
