Apparatus for linearly displacing a rotatable spindle

An apparatus is disclosed for linearly displacing a rotatable spindle relative to an object. The apparatus includes a support that is connectable to the spindle such that translation of the spindle relative to the support in a first direction is restrained, a rotatable shaft which is connected to the support such that translation of the shaft relative to the support in the first direction is restrained, and a rotational drive system rotatably connected to the shaft and rotatably connectable to the spindle, to transmit rotational drive from the spindle to the shaft. The apparatus also includes a contact piece eccentrically mounted to the shaft, wherein the contact piece has a contact surface thereon for contact with the object. Rotation of the shaft varies a distance, measured in the first direction, between the support and a portion of the contact surface contacting the object, such that the spindle is linearly displaceable relative to the object.

Wood lathe

A bench type router/shaper which includes (i) a spindle drive pack which incorporates the motor and the spindle into a unitary package so as to establish and maintain a spacial relationship between the motor and the spindle, (ii) a semi-elastic drive belt encompassing the spindle and drive shaft which has a modulus of elasticity effective for providing effective power transmission while permitting removal and replacement of the drive belt without repositioning of the spindle and/or the drive shaft, (iii) a spindle adjustment mechanism for repositioning the longitudinal position of the spindle and thereby the depth of the cutter which includes a rotatable bell crank, a spindle in communication with the first extremity of the bell crank for linear movement of the spindle based upon rotational movement of the bell crank, and a rotatable handle in communication with the second extremity of the bell crank for producing rotation of the bell crank based upon rotation of the handle and (iv) a protective shield over the cutter which provides maximum protection with minimal interference and includes a horizontal plate which is laterally pivotable about a first pivot point proximate the right end of the horizontal plate, and a vertical plate which is longitudinally pivotally connected to the horizontal plate about a second pivot point proximate the left end of both plates.

Disclosed is a measurement system magnetic coupler. The system comprises reader head apparatus for establishing a measurement related to the location of a physical structure moveable along a predetermined path. The system also includes a magnet for coupling the reader head apparatus to the physical structure by magnetic attraction between the magnet, the reader head apparatus, and the physical structure.

Measurement system display module

Disclosed is a measurement system having multiple display orientations. The measurement system comprises a reader head having a reader element, and a display module. The reader element is configured for lateral movement with respect to a calibrated reference member for making a measurement relative to a reference position on the calibrated reference member. The display module is for displaying a measurement and includes coupling hardware for connecting the display module to the reader head so that the display module can be read horizontally independent of whether the reader head is oriented horizontally, vertically, or in some other direction.

Measurement system having multiple display orientations

Disclosed is a measurement system having reader element standoff. The system comprises a calibrated reference member for use with a reader head in making a measurement. The system also includes a reader head comprising a reader element configured to move laterally with respect to the calibrated reference member for making the measurement relative to a reference position on the calibrated reference member. Also, standoff structure is provided for establishing a variable standoff distance between the reader element and the calibrated reference member while substantially invariably maintaining a fixed lateral position of the reader element within the reader head.

Measurement system reader element standoff

Disclosed is a measurement system for providing a direct reading of a position on either side of a reference position. The system comprises a reader head including a reader element configured to move laterally with respect to a calibrated reference member for making a measurement relative to a reference position. The measurement system also includes mode display apparatus for increasing or decreasing the measurement which is displayed as the reader element moves away from or toward a selected side of the reference position.

Motorized saw unit

Disclosed is a capacitive measurement system. The system comprises structure for generating a plurality of waveforms, a calibrated reference member for use with a reader head in making a measurement, and a reader element configured for lateral movement with respect to the calibrated reference member. The calibrated reference member comprises one element of a capacitor. The reader element comprises a plurality of reader regions comprising the other element of the capacitor. The reader element also includes structure for receiving two signals resulting from coupling of the two capacitor elements. The system functions to detect a phase shift level between the two signals and to determine magnitude of lateral movement in a particular direction from the magnitude of the phase shift.
