Abstract
Abstract An automatic line-up table structure having a rectangular table top and a straight edge member which is operable thereover. The straight edge member has guide members operable in ways adjacent opposite side edges of said table top and the straight edge member has members operatively connected to moving members at said opposite side edges operable by an impulse stepping motor whereby activation of the motor moves the straight edge member. Controls for said motor include a micrometer indexing unit and circuitry therefor whereby the straight edge member is selectively moved in selected directions and in predetermined increments between accurate parallel positions for each impulse imparted to the motor.

Claim 1
Independent Claim
385 words
A line up table comprising: a. a generally rectangular table top frame having a planar work surface and a pair of opposed end edges, b. an elongate straight edge member above said table top planar work surface and frame, c. a guide housing mounted on each end of said straight edge member in supporting relation thereto, each guide housing having walls defining a chamber therein, d. an elongate threaded shaft rotatably mounted adjacent each end edge of one pair of opposed end edges of said table top frame, said shafts being parallel, each said threaded shaft extending through the chamber in a respective guide housing, said shafts each being normal to said straight edge member, e. an internally threaded member mounted within the chamber of each of said guide housings and sleeved on said respective threaded shafts extending through said chamber, said respective threaded shafts being rotatably engaged within said respective internally threaded members to move same longitudinally of said shafts, f. an impulse stepping motor and power transmission means carried by said table top frame and operatively connecting said stepping motor to each of said threaded shafts for simultaneously and equally rotating same to move said guide housings and thereby moving said straight edge member over said work surface, and g. Control means mounted adjacent to said table and including a control unit having adjustable means to vary the number of pulses imparted to said stepping motor thereby controlling the number of incremental rotations of said motor and hence the number of incremental rotations of said threaded shaft and thereby controlling the amount of linear movement of said straight edge member over said table top. h. recessed guideways in an upper surface of said table top frame adjacent each side edge of said one pair of opposed side edges thereof to define the path of movement of said straight edge member, each guideway being parallel with a respective threaded shaft, i. a guide member mounted on said straight edge member adjacent to and spaced from from said guide housing at each end edge thereof and received in a respective guideway, said guide members having sliding engagement with said guideways and cooperating with the guide housings, threaded members therein and the elongate threaded shafts to maintain position to position parallelism of said straight edge member.
