Abstract
Abstract A cutting device includes an annular cutting member for cutting a crystal into slices which have smooth and parallel surfaces. The crystal is supported by a crystal holder in a rotatable head and is cut into slices which are aligned with the crystal axis with a high degree of precision. The cut slices are safely and readily removed by a takeout means which is provided beneath the annular cutting member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
154 words
In a device having an annular cutting member provided with a cutting edge at the inner periphery thereof for cutting a crystal into slices, the combination comprising: a base; rotary means on said base for supporting said annular cutting member in a given plane; drive means operatively connected to said rotary means for continuously driving said cutting member; a block member inclinably adjustably mounted on said base; a table slidably disposed on said block member; a crystal holder attached to said sliding table being independently rotatable in two vertical planes which intersect each other at right angles; feed means for intermittently feeding said crystal held by said crystal holder through a predetermined dimension; take-out means in said rotary means opposite said cutting member from said crystal holder for receiving said crystal slices; and means for moving said take-out means axially of said rotary means and through the central opening of said annular cutting member.
Claim 2
Dependent Claim
154 words
In a device having an annular cutting member provided with a cutting edge at the inner periphery thereof for cutting a crystal into slices, the combination comprising: a base; rotary means on said base for supporting said annular cutting member in a given plane; drive means operatively connected to said rotary means for continuously driving said cutting member; a block member inclinably adjustably mounted on said base; a table slidably disposed on said block member; a crystal holder attached to said sliding table being independently rotatable in two vertical planes which intersect each other at right angles; feed means for intermittently feeding said crystal held by said crystal holder through a predetermined dimension; take-out means in said rotary means opposite said cutting member from said crystal holder for receiving said crystal slices; and means for moving said take-out means axially of said rotary means and through the central opening of said annular cutting member.
Claim 3
Dependent Claim
36 words
A device in accordance with claim 9 wherein said block member is attached at one side to said base through a wedge so as to adjust the angle of inclination thereof by movement of said wedge.
Claim 4
Dependent Claim
23 words
A device in accordance with claim 1 further including means for periodically and automatically changing the length of stroke of said sliding table.
Claim 5
Dependent Claim
38 words
A device in accordance with claim 3 wherein said means for changing the length of stroke of said sliding table includes a plurality of limit switches attached to said block member and feelers attached to said sliding table.
Claim 6
Dependent Claim
24 words
A device in accordance with claim 1 wherein said feed means includes a pulse motor and a gear mechanism connected to said pulse motor.
Claim 7
Dependent Claim
70 words
A device in accordance with claim 9 wherein said take-out means means comprises a rotatable shaft mounted for movement along its axis , a receiving table attached to the top end of said shaft movable to one side in response to rotation of said shaft and movable with said shaft in the direction of said shaft axis, and means for rotating said shaft and moving said shaft along its axis.
Claim 8
Dependent Claim
58 words
A device in accordance with claim 9 wherein said crystal holder is rotatably attached to said sliding table for adjusting the crystal axis in two planes which intersect at right angles with each other, and further comprising two angle adjusting means independently operable for adjusting the angle of inclination of said crystal holder in said two vertical planes.
Claim 9
Dependent Claim
48 words
A device in accordance with claim 7 wherein said crystal holder includes a cover movable relative to the plane of said annular cutting member so as to adjust the distance between said annular cutting member and the lower end of said cover when said crystal holder is inclined.
