Abstract

Abstract An improved method and means for grinding and polishing articles. The items to be polished and the desired or required amount of grit-bearing grinding liquid, are sealed within a disposable, leakproof bag, and the bag and contents are then tumbled until the desired amount of polishing is effected. The disposable leakproof bag may be prepackaged as the container for a premeasured amount of grinding grit, and be of such a predetermined capacity that when filled to a prescribed level with the liquid and items to be polished, the proper proportion or ratio of liquid to grit will automatically be effected. The rotating device is preferably the inside lower end of a broad, closed belt loop gravitationally suspending from, and driven by, an overhead rotatable shaft. For finer polishing, successive stages employing increasingly finer grinding grit may be employed.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 91 words
A tumbling apparatus for use in the fluid grinding method of polishing articles, comprising in combination a disposable yieldable leakproof container containing a prepackaged quantity of grinding grit and for receiving the articles therein, a vertically-hanging closed belt loop for removably supporting the filled container, a rotatable shaft having a diameter smaller than the cross-sectional dimension of the filled container for supporting the closed belt loop, and a mean operably connected to the shaft for transmitting rotation thereto to revolve the closed belt loop for tumbling the container and contents thereof.
Claim 2
Dependent Claim 91 words
A tumbling apparatus for use in the fluid grinding method of polishing articles, comprising in combination a disposable yieldable leakproof container containing a prepackaged quantity of grinding grit and for receiving the articles therein, a vertically-hanging closed belt loop for removably supporting the filled container, a rotatable shaft having a diameter smaller than the cross-sectional dimension of the filled container for supporting the closed belt loop, and a mean operably connected to the shaft for transmitting rotation thereto to revolve the closed belt loop for tumbling the container and contents thereof.
Claim 3
Dependent Claim 166 words
An improved process for grinding and polishing articles, comprising the steps of placing the articles to be polished and a fluid grinding mixture in a disposable leakproof container, sealing said filled container, tumbling said sealed container an contents a sufficient length of time to effect a desired degree of grinding and polishing, wherein the step of tumbling comprises subsequent steps of terminating the tumbling when an intermediate degree of polishing has been effected, removing the intermediately polished articles from the leakproof container, cleansing the articles of the grinding mix, disposing of the disposable container and its residual contents, placing the cleansed intermediately polished articles and a second grinding mixture in a second disposable leakproof container, sealing said filled second disposable leakproof container, tUmbling said second sealed disposable leakproof container and contents a sufficient length of time to effect a second desired degree of grinding and polishing, and repeating the process through a sufficient number of stages as necessary to achieve the ultimate desired degree of polishing.
Claim 4
Dependent Claim 166 words
An improved process for grinding and polishing articles, comprising the steps of placing the articles to be polished and a fluid grinding mixture in a disposable leakproof container, sealing said filled container, tumbling said sealed container an contents a sufficient length of time to effect a desired degree of grinding and polishing, wherein the step of tumbling comprises subsequent steps of terminating the tumbling when an intermediate degree of polishing has been effected, removing the intermediately polished articles from the leakproof container, cleansing the articles of the grinding mix, disposing of the disposable container and its residual contents, placing the cleansed intermediately polished articles and a second grinding mixture in a second disposable leakproof container, sealing said filled second disposable leakproof container, tUmbling said second sealed disposable leakproof container and contents a sufficient length of time to effect a second desired degree of grinding and polishing, and repeating the process through a sufficient number of stages as necessary to achieve the ultimate desired degree of polishing.
Claim 5
Dependent Claim 111 words
An improved process for grinding and polishing articles, comprising the steps of placing the articles to be polished and a fluid grinding mixture in a disposable leakproof container, sealing said filled container, tumbling said sealed container and contents a sufficient length of time to effect a desired degree of grinding and polishing, wherein the placing of the articles and the grinding mix in the disposable leakproof container includes the steps of prepackaging a premeasured amount of grinding grit in the disposable leakproof container, opening the said prepackaged disposable leakproof container, placing said articles in said prepackaged container, and adding liquid to the contents of the container prior to the sealing thereof.
Claim 6
Dependent Claim 111 words
An improved process for grinding and polishing articles, comprising the steps of placing the articles to be polished and a fluid grinding mixture in a disposable leakproof container, sealing said filled container, tumbling said sealed container and contents a sufficient length of time to effect a desired degree of grinding and polishing, wherein the placing of the articles and the grinding mix in the disposable leakproof container includes the steps of prepackaging a premeasured amount of grinding grit in the disposable leakproof container, opening the said prepackaged disposable leakproof container, placing said articles in said prepackaged container, and adding liquid to the contents of the container prior to the sealing thereof.
Claim 7
Dependent Claim 24 words
An improved process for grinding and polishing articles as described in claim 2, wherein the grinding mixture comprises a liquid and grinding grit combination.
Claim 8
Dependent Claim 33 words
An improved process for grinding and polishing articles as described in claim 4 wherein the grit used in the sequential grinding stages is of a successively finer size to provide increasingly finer polishing.
Claim 9
Dependent Claim 18 words
An improved process for grinding and polishing articles as described in claim 5 wherein the liquid is water.
Claim 10
Dependent Claim 20 words
An improved process for grinding and polishing articles as described in claim 5, wherein the liquid is essentially water based.
Claim 11
Dependent Claim 40 words
An improved process for grinding and polishing articles as set forth in claim 3 herein a predetermined quantity of liquid is added to the contents of the container to provide an optimum ratio between the liquid and the premeasured grit.
Claim 12
Dependent Claim 62 words
A tumbling apparatus for use in the grinding fluid method of polishing as described in claim 1, wherein the sides of the vertically hanging belt loop are distented by the weight and size of the filled, yieldable container supported therein, said distented sides providing an inward squeeze against the container to impress a centripetal pressure against the contents of the yieldable container.
