专利汇可以提供Machine tool and gaging apparatus专利检索，专利查询，专利分析的服务。并且The disclosed gaging apparatus is primarily applicable to grinding machines, but is also applicable to other machine tools. The apparatus comprises a gaging head having a movable gaging member with a contact element made of extremely hard material for direct engagement with grinding wheel. Such engagement moves the gaging member to a position corresponding to the size of the workpiece after being ground by the wheel. The gaging head is provided with a clamping magnet or other device for mounting the gaging head on the workpiece or the work support. Retaining means are provided to hold the movable gaging member in any position to which it may be moved, such retaining means preferably providing frictional resistance to movement of the gaging member. The retaining means may comprise a magnet to produce a retaining force or a frictional spring acting between the gaging member and the gaging head. An indicator is provided for precisely indicating the position of the gaging member. Such indicator may be of an electronic or pneumatic type, for example.，下面是Machine tool and gaging apparatus专利的具体信息内容。

Apparatus according to claim 1, in which said gaging head includes a bore for receiving said gaging member, said gaging member including a pin slidable in said bore, said pin including magnetizable material, said retaining means including magnetic means to act on said magnetizable material for producing a retaining force between said gaging member and said gaging head.
7. Apparatus according to claim 1, in which said retaining means comprises a resilient frictional element acting between said gaging member and said gaging head to hold said gaging member in any position to which it may be moved.
8. Apparatus according to claim 1, in which said gaging head comprises an opening for guiding said gaging member, said gaging member having a portion which is slidably received in said opening, said retaining means comprising a friction spring acting between said gaging member and said gaging head to hold said gaging member in any position to which it may be moved.
9. Apparatus according to claim 1, in which said gaging head comprises an opening for guiding said gaging member, said gaging member including a pin which is slidable in said opening, said retaining means including a friction spring mounted on said pin and frictionally engaging the inside of said opening to hold said gaging member in any position to which it may be moved.
10. Apparatus according to claim 1, in which said mounting means includes a clamping magnet on said gaging head.
11. Apparatus according to claim 1, in which said responsive means includes an electronic indicator.
12. Apparatus according to claim 1, in which said responsive means includes an air indicator.
13. Apparatus according to claim 1, in which said contact element includes extremely hard material to withstand the grinding action of said grinding wheel.
14. Machine tool and gaging apparatus, comprising a stock removing tool, a work support for holding at least one workpiece to be acted upon by said tool, means mounting said work support and said tool for relative feeding movement, a gaging head, mounting means for holding said gaging head in a fixed relation to the workpiece, a movable gaging member mounted on said gaging head for movement relative thereto, said gaging member having a contact element thereon for direct engagement with said tool, such engagement being effective to move said gaging member relative to said gaging head to a position corresponding to the size of the workpiece after being acted upon by said tool, retaining means for holding said gaging member in any position to which it may be moved, and responsive means for precisely representing the position of said gaging member, whereby the reduction of the workpiece to a particular desired size will be represented by a predetermined response of said responsive means when the tool and the gaging member are brought into engagement.
15. Machine tool and gaging apparatus according to claim 14, in which said retaining means comprises means for producing frictional resistance to movement of said gaging member relative to said gaging head, whereby the position of said gaging member is frictionally maintained after engagement of said gaging member with the tool.
16. Machine tool and gaging apparatus according to claim 14, in which said retaining means comprises magnetic means for producing frictional resistance to movement of said gaging member relative to said gaging head.
17. Machine tool and gaging apparatus according to claim 14, in which said gaging member has a portion which is slidable relative to said gaging head, said retaining means including magnetic means for producing a retaining force between said gaging member and said gaging head.
18. Machine tool and gaging apparatus according to claim 14, in which said retaining means comprises a resilient frictional element acting between said gaging member and said gaging head to hold said gaging member in any position to which it may be moved.
