Abstract
Abstract A device for temporary attachment over the spindle arm of a boring machine to enable the precise positioning of a boring tool in the machine. The tool setting device comprises a mounting element and an adjustable carriage slidably attached to the mounting element, the exact positioning of the carriage on the mounting element being made possible by the cooperation of a ture scale on the latter with a vernier on the carriage. The carriage also comprises an indicator gauge which is adjustably secured thereto and which is adapted to correlate the position of the carriage on the mounting element with the axis of rotation of the spindle and to indicate the precise position at which the cutting bit of the boring tool should be secured in the machine in order to bore a hole having the precise dimensions indicated by the vernier.

Claim 1
Independent Claim
355 words
A tool setting device adapted to be attached to a boring machine for purposes of precisely setting a cutting tool in the spindle of a boring machine, the device comprising a mounting element and a carriage element slidably attached to the mounting element, said mounting element comprising base means adapted to releasably attach the device over the spindle of a boring machine comprising a contractable collar adapted to encircle the spindle of the boring machine and to be tightened in centered position thereover and a scale member column extending from said base means in a direction which is perpendicular to the axis of the spindle when the device is attached thereover and containing a true scale having graduations corresponding to the dimension of the hole to be cut by the cutting tool, said carriage element comprising vernier means slidably attaching said carriage element to said scale member column and including a vernier scale in cooperative association with said true scale to enable the precise adjustment of the carriage element relative to the mounting element corresponding exactly to the desired setting of the cutting tool, an extension element fixed to and extending from said vernier element, an indicator element fixed to said extension element and comprising an indicator dial gauge which is adjustably mounted on said indicator element, means for adjusting the position of said indicator gauge relative to said indicator element in a direction parallel to said scale member column and towards and away from the axis of the spindle to indicate the location of said axis, and means for locking said indicator gauge to said indicator element at an adjusted position corresponding to the axis of said spindle, whereby in use said indicator gauge can be adjusted and locked on said indicator element at a position corresponding to the location of the axis of the spindle relative to said true scale and said carriage element can be precisely positioned relative to said true scale by means of said vernier scale to position the indicator element A precise distance from the axis of the spindle corresponding to the diameter of the hole to be bored.

A tool setting device adapted to be attached to a boring machine for purposes of precisely setting a cutting tool in the spindle of a boring machine, the device comprising a mounting element and a carriage element slidably attached to the mounting element, said mounting element comprising base means adapted to releasably attach the device over the spindle of a boring machine comprising a contractable collar adapted to encircle the spindle of the boring machine and to be tightened in centered position thereover and a scale member column extending from said base means in a direction which is perpendicular to the axis of the spindle when the device is attached thereover and containing a true scale having graduations corresponding to the dimension of the hole to be cut by the cutting tool, said carriage element comprising vernier means slidably attaching said carriage element to said scale member column and including a vernier scale in cooperative association with said true scale to enable the precise adjustment of the carriage element relative to the mounting element corresponding exactly to the desired setting of the cutting tool, an extension element fixed to and extending from said vernier element, an indicator element fixed to said extension element and comprising an indicator dial gauge which is adjustably mounted on said indicator element, means for adjusting the position of said indicator gauge relative to said indicator element in a direction parallel to said scale member column and towards and away from the axis of the spindle to indicate the location of said axis, and means for locking said indicator gauge to said indicator element at an adjusted position corresponding to the axis of said spindle, whereby in use said indicator gauge can be adjusted and locked on said indicator element at a position corresponding to the location of the axis of the spindle relative to said true scale and said carriage element can be precisely positioned relative to said true scale by means of said vernier scale to position the indicator element A precise distance from the axis of the spindle corresponding to the diameter of the hole to be bored.
Claim 3
Dependent Claim
44 words
A tool setting device according to claim 1 in which a threaded drive member is rotatably mounted on said mounting element and threadably engages said carriage element to facilitate the precise adjustment of the position of the vernier scale relative to the true scale.
Claim 4
Dependent Claim
43 words
A tool setting device according to claim 2 in which said carriage element is provided with means for releasing the engagement with said threaded drive member to permit the free adjustment of the position of the vernier scale relative to the true scale.
Claim 5
Dependent Claim
31 words
A tool setting device according to claim 1 in which the collar is provided with a contractable adapter collar to adapt the device for use on a spindle of reduced diameter.
Claim 6
Dependent Claim
64 words
A tool setting device according to claim 1 in which said indicator element comprises a housing fixed to said extension element, a drive element rotatably mounted within said housing, said indicator gauge being threadably engaged by said drive element for movement towards and away from said housing, and a locking member for securing the indicator gauge at any desired position relative to the housing.
Claim 7
Dependent Claim
28 words
A tool setting device according to claim 1 in which the extension element of the carriage element is removable for replacement by another extension element of different length.
