3 Claims. 1
This invention re1ates in general te electronic gauges and more particularly te gauge heads and has for ene of its primary objects te provide an improved dspl-acement pickup unit te inc]ude a driving coil and a pair of pickup cols, the pickup cols being contained in -a single coil form and arranged concentricalhr with respect te the driving ceil, the windings of the three cols being coaxial- ]y arrangecl, whereby the driving coil may fixed1y carry an iron er air core and be dsposed for rela- =tive iengitudinal -movement either inside of er outside of the pickup cols er thepickup coil ferm may carry the core and be disposed within the driving coil for relative longitudinal movement.
With the oregoing and other objects in view the nvention consists in the cembination of Darts and in the details of construction hereinaiter set i'orth in the foilowing specfication and appended claims, certan embodiments thereof being illustrated in the accompanying drawings, in which:
Fgure 1 is a schematic sectional illustratien of one form of gauge head and wiring diagram te include the osciilator and eiectrenic voltmeter circuit, the two pickup cols being stationary and the drivng coil carrying an iron core for movement longitudinailyinside the two pickup cols;
Figure 2 is a similar view of a similar arrangement showing an air core instead of an iren core;
Figure 3 is a smilar view of a medified form in which the pickup cols are stationary and earry the iron core and the drivng coil is mevable longitudinally outside of the pickup cols Figure 4 is a view simiiar te Figure 3 ei a form in which the pickup cols with the ron core are longtudinally movabie inside the stationary driving coil; and
Figure 5 is a view similar to Figures 3 and 4 in which the driving and pickup cols are both movable longitudinaliy with respect to each ether.
Referring more par-ticularly te the drawings, Figure 1 shows ene form of the invention in which the heusing shown schematically at I ha.s anchored therete a coil form 2 with a pair of 1on gtudinally arranged pickup cols 3 and. 4. Suit ab1y arranged fer iengitudinal mevement within mature are of lesser diameter and fixed to a stationary support while the .driving coil 3 is meunted cencentricaily about the pickup cols the two pickup cols is a driving coil 5 in a coil ter movement longitudinally thereof.
In Figure 4 the same general arrangement of Figure 3 is shown except that the driving coil 9 is fixed te a stationary support and the =pickup coiis I0 and I I with their armature are movable longitudinally of the driving coil.
In Figure 5 the same general arrangement of Figures 3 and 4 is shown except that the driving coil 9 and the pickup 00115 [0 and II with their armature are both movable longitudinaliy with respect te each other.
In each instance the driving coil is arranged concentricall with respect to the twe pickup cols and the armature is fixed te ether the driving coil or the pickup cols. In each instance the windings of the cols are coaxiaily arranged and the armature is fixed te one and movable with respect te another type of coil.
Also in each modification the wiring diagram includng 1eads from the cols te a circuit including a Vacuum tube oscllator and electronic veltmeter =circuit are similar to each ether and gen erally similar to that shown in the U. S. Patent te Joseph J. Neif fer Electrical caliper, No. 2364,237
dated December 5, 1944.
I claim:
1. In an eiectrcaldisplacement =pickup mechanism, a pair of longitudinaily arranged contiguous pickup coi1s of uniform outside diameters and coaxial windings, a drivng k:ei1 disposed concentrically with respect to said pickup cols, an armature arrangecl concentrically within all of sad cols and attached te one or more of said cols, said driving coil and said pickup cols beng mounted te be relatively movable iongitudnally of each other.
2. In an electrical displacement pickup mechanism, a pair of longitudnaily arranged contigueus pckup 00115 of uniform outside diameters and ceaxial windings, a. driving coil. dis-posed concentricaily within said Pckup cols, an armature er ranged concentrically within all of said cols and attached .to one or more of'said cols, said driving coil and said pickup cols being mounted te be relatvely mevable longitudinally of each ether.
3. In en electrical displacemerit pickup mechanism, a pair of longitudinally arranged contiguous pickup cols of uniform outside diameters and coaxial windings, a driving coil dispesed concentrically within said pickup cols, an armature arranged concentrically within all of said cols and said plckup col1s.
