Abstract
Abstract An apparatus for washing and drying phonograph records including a tank to contain a washing solution, and a phonograph record to be cleaned is mounted vertically for rotation within the tank. The washing solution is drawn in the bottom of the tank by a pump and discharged through jets against opposite faces of the rotating record. Mounted adjacent the jets is a pair of brushes which rotate against the opposite faces of the record to clean the same. After cleaning, air is discharged downwardly from an air tube against the opposite faces of the record to prevent the washing solution from dripping onto the record label and to the dry the record.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
224 words
An apparatus for washing and drying a phonograph record having a central label, comprising a container to contain a washing liquid, means disposed within the container for mounting a record for rotation about a horizontal axis, means for rotating the record, a pair of discharge jets disposed in spaced relation within the container and positioned to direct a washing liquid against opposite faces of the record, pumping means for delivering the washing liquid to said jets, a pair of brushes mounted for rotation about vertical axes and disposed circumferentially in the direction of record rotation from said jets, said brushes disposed to rotate in contact wth opposite faces of the record to clean the same, and air discharge means disposed circumferentially in the direction of record rotation from said brushes and disposed at a level above the jets, said pumping means and said air discharge means being operable simultaneously said air discharge means including an elongated open ended slot to receive the rotating record, said air discharge means being provided with downwardly directed elongated air discharge passages on either side of the slot for directing air downwardly against opposite faces of the record to remove the washing liquid and dry said surfaces and prevent the liquid from dripping downwardly into contact with the label as the record rotates upwardly beyond said air discharge means.
Claim 2
Independent Claim
224 words
An apparatus for washing and drying a phonograph record having a central label, comprising a container to contain a washing liquid, means disposed within the container for mounting a record for rotation about a horizontal axis, means for rotating the record, a pair of discharge jets disposed in spaced relation within the container and positioned to direct a washing liquid against opposite faces of the record, pumping means for delivering the washing liquid to said jets, a pair of brushes mounted for rotation about vertical axes and disposed circumferentially in the direction of record rotation from said jets, said brushes disposed to rotate in contact wth opposite faces of the record to clean the same, and air discharge means disposed circumferentially in the direction of record rotation from said brushes and disposed at a level above the jets, said pumping means and said air discharge means being operable simultaneously said air discharge means including an elongated open ended slot to receive the rotating record, said air discharge means being provided with downwardly directed elongated air discharge passages on either side of the slot for directing air downwardly against opposite faces of the record to remove the washing liquid and dry said surfaces and prevent the liquid from dripping downwardly into contact with the label as the record rotates upwardly beyond said air discharge means.
Claim 3
Dependent Claim
28 words
The apparatus of claim 1, wherein the brushes have a length substantially equal to the distance between the periphery of the record and the label on the record.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1, wherein said air discharge means is disposed approximately 90° from said brushes.
Claim 5
Dependent Claim
58 words
The apparatus of claim 1, wherein each brush includes a plurality of flexible bristles, said bristles disposed to hang downardly out of contact with the respective faces of the record when the brushes are not rotating and said bristles being thrown outwardly by centrifugal force into contact with the faces of the record on rotation of said brushes.
Claim 6
Dependent Claim
63 words
The apparatus of claim 1, wherein said air discharge means includes a generally horizontal tube having an inlet end and a pair of spaced generally parallel arms which define said slot, said discharge passages being located in the respective arms adjacent said slot, and said air discharge means including fan means operably connected to said inlet end to deliver air to said tube.
