Abstract: A 45 rpm record adaptor body is positioned at the center of the turntable and has a record supporting shelf on one side and a shoulder opposite said shelf. The distance from the inner edge of said shelf to the bottom of said shoulder is slightly greater than the hole diameter of a 45 rpm record so that one side of a stack of 45 rpm records placed on said body is supported on said shelf and the other side of the stack is supported on said shoulder. The shelf is undercut to a point at which the distance to the bottom of said shoulder is less than the hole diameter of a 45 rpm record to permit an ejected record to move off of said shoulder and onto the turntable.

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.

Abstract: An adaptor to be employed in conjunction with a phonograph record spindle which is to accommodate a stacked assemblage of phonograph records. The adaptor is to facilitate locating of individual records onto the adaptor, yet also permits easy removal of the entire stacked assemblage of records. The adaptor includes a cylindrical enlarged exterior surface which terminates at its lower end thereof in an annular protruding flange. The bottom record of the stacked records is to rest against this flange. A centrally located opening is formed within the adaptor and is to accommodate the phonograph record spindle. This opening is to have a side wall which is to function to continually depress an outwardly biased elongated blade which is pivotally mounted in conjunction with the spindle. This blade is deemed to be part of conventional phonograph record apparatus and forms no specific part of this invention. The upper end of the adaptor is tapered so as to guide the insertion of the phonograph records upon the adaptor.
