Abstract
Abstract A feeler device comprising a freely rotatable feeler wheel member having three active surfaces lying on an imaginary cylinder. The feeler member is mounted on an arm and rests by its own weight against a supporting surface. The leading edge of a movable sheet formed blank strikes one of the the active surfaces and turns the feeler wheel so that it is lifted from the supporting surface and thereby moves the arm which activates a switch that causes the sheet-formed blank to stop its movement on the supporting surface. After a certain degree of rotation, another active surface of the feeler wheel rests upon the supporting surface and is thereafter engaged by the leading-edge of the next movable sheet-formed blank.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
A feeler device for photocopying apparatus or the like, adapted to feel the sliding movement of a sheet-like blank along a support surface; comprising a feeler having at least three peripherally spaced surfaces distributed over an imaginary cylinder; means rotatably supporting said feeler so as to be freely rotatable about an axis located above said supporting surface transversely of the direction of movement of the blank, said spaced surfaces extending at a greater radial distance from the axis of rotation than the remaining portion of the feeler and adapted to be respectively contacted by the leading edge of the blank upon sliding movement of the latter along said support sufface so as to impart rotation to said feeler about its axis; a pivoting arm means connected to said feeler; and microswitch means being operatively connected with said pivoting arm means so as to cause said blank to stop movement along said support surface in response to a predetermined position of said feeler.
Claim 2
Dependent Claim
162 words
A feeler device for photocopying apparatus or the like, adapted to feel the sliding movement of a sheet-like blank along a support surface; comprising a feeler having at least three peripherally spaced surfaces distributed over an imaginary cylinder; means rotatably supporting said feeler so as to be freely rotatable about an axis located above said supporting surface transversely of the direction of movement of the blank, said spaced surfaces extending at a greater radial distance from the axis of rotation than the remaining portion of the feeler and adapted to be respectively contacted by the leading edge of the blank upon sliding movement of the latter along said support sufface so as to impart rotation to said feeler about its axis; a pivoting arm means connected to said feeler; and microswitch means being operatively connected with said pivoting arm means so as to cause said blank to stop movement along said support surface in response to a predetermined position of said feeler.
Claim 3
Dependent Claim
72 words
A feeler device as claimed in claim 1, said feeler comprising an equilateral triangularly-shaped disc having concavely formed side surfaces, the points of said triangle being chamfered to form said three spaced surfaces, said surfaces being each inclined so that the surface contacted by the leading edge of the blank is at right angles to said supporting surface when two of said spaced surfaces of said feeler rest on said support surface.
Claim 4
Dependent Claim
59 words
A feeler device as claimed in claim 1, comprising shaft means supporting said feeler for rotation about its axis, said pivoting arm means supporting said shaft means so as to be swingable in a plane extending at right angles with said supporting surface; and said microswitch means having a pivotable operating member operatively connected with said pivoting arm means.
