Abstract
Abstract An apparatus for adjusting the position of a front cover for a grinding wheel guard comprises the front cover being pivotally mounted by a hinged pin at the front upper part of the grinding wheel guard, a first revolving member being secured to the front cover with its axis in parallel relation with the hinged pin, a second revolving member being secured to the grinding wheel guard with its axis in parallel relation to the hinged pin, and an adjusting screw having a flange biased against one of the first and second revolving members and being connected to the other of the first and second revolving members and to a handle. The first revolving member is connected to the front cover for limited relative rotation with respect thereto by a pin and slot arrangement, whereby upon movement of the first revolving member in the axial direction of the adjusting screw, the front cover is turned either in a clockwise or counterclockwise direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
240 words
An apparatus for adjusting the position of a front cover for a grinding wheel guard being pivotally mounted by a hinged pin to the front upper part of the grinding wheel guard, comprising: first revolving means on the front cover being held for relative movement about an axis parallel to the hinged pin: second revolving means on the grinding wheel guard being held for relative movement about an axis parallel to the hinged pin; an adjusting screw having a first flange means faced against one of said frist and second revolving means and being connected to the other of said first and second revolving means and to a handle for causing pivotal movement of said front cover about said hinged pin; said handle including second flange means faced against one of said first and second revolving means, wherein said first and second flange means transmit motion from said screw and said handle to said one of said first and second revolving means for pivoting said cover relative to said guard; and means for releasing said first and second flange means from said one of said first and second revolving means so that said screw and said handle are pivotable to an out-of-the-way position about said other one of said first and second revolving means and whereby said front cover may also be pivoted about said hinged pin to an out-of-the-way position so as to permit access to said grinding wheel.
Claim 2
Independent Claim
240 words
An apparatus for adjusting the position of a front cover for a grinding wheel guard being pivotally mounted by a hinged pin to the front upper part of the grinding wheel guard, comprising: first revolving means on the front cover being held for relative movement about an axis parallel to the hinged pin: second revolving means on the grinding wheel guard being held for relative movement about an axis parallel to the hinged pin; an adjusting screw having a first flange means faced against one of said frist and second revolving means and being connected to the other of said first and second revolving means and to a handle for causing pivotal movement of said front cover about said hinged pin; said handle including second flange means faced against one of said first and second revolving means, wherein said first and second flange means transmit motion from said screw and said handle to said one of said first and second revolving means for pivoting said cover relative to said guard; and means for releasing said first and second flange means from said one of said first and second revolving means so that said screw and said handle are pivotable to an out-of-the-way position about said other one of said first and second revolving means and whereby said front cover may also be pivoted about said hinged pin to an out-of-the-way position so as to permit access to said grinding wheel.
Claim 3
Independent Claim
56 words
The apparatus of claim1, wherein one end of the adjusting screw is screwed to the second revolving means transversely crossing the axis of rotation of said second revolving means, and the other end of the adjusting screw is fitted to the center of a handle shaft of said handle so as to be axially slidable therein.
Claim 4
Dependent Claim
39 words
The apparatus of claim 1, wherein said first revolving means has an arcuate hole which receives a pin projecting from a holder thereof secured to the front cover to limit the range of turning of said first revolving means.
Claim 5
Independent Claim
160 words
An apparatus for adjusting the position of a front cover for a grinding wheel guard being pivotally mounted by a hinged pin to the front upper part of the grinding wheel guard, comprising: first revolving means on the front cover being held for relative movement about an axis parallel to the hinged pin; second revolving means on the grinding wheel guard being held for relative movement about an axis parallel to the hinged pin; an adjusting screw having a flange faced against one of said first and second revolving means and to a handle for causing pivotal movement of said front cover about said hinged pin; and wherein a spring is disposed between a handle shaft of said handle and the adjusting screw for biasing the two apart, and a pin projects radially from the adjusting screw and is connected to an elongate hole in the handle shaft whereby rotation of the handle shaft is transmitted to the adjusting screw.
Claim 6
Independent Claim
160 words
An apparatus for adjusting the position of a front cover for a grinding wheel guard being pivotally mounted by a hinged pin to the front upper part of the grinding wheel guard, comprising: first revolving means on the front cover being held for relative movement about an axis parallel to the hinged pin; second revolving means on the grinding wheel guard being held for relative movement about an axis parallel to the hinged pin; an adjusting screw having a flange faced against one of said first and second revolving means and to a handle for causing pivotal movement of said front cover about said hinged pin; and wherein a spring is disposed between a handle shaft of said handle and the adjusting screw for biasing the two apart, and a pin projects radially from the adjusting screw and is connected to an elongate hole in the handle shaft whereby rotation of the handle shaft is transmitted to the adjusting screw.
