Abstract
Abstract A crank handle for driving a tape drum of a tape measure is pivotally mounted on an accessible side flange of the drum for movement between a rest position nested in a recess of the flange and a protruding winding position. The pivoting shaft of the crank handle is disposed in an eccentric groove in the underneath face of the flange, this groove having a central portion communicating with the recess. The crank handle is mounted for rotation about and limited sliding movement along a second shaft, and preferably houses spring means biasing it towards the pivoting shaft to hold it in either the rest or winding position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
In a tape measure including a rotatable tape-drum having a rotary flange and a crank handle eccentrically mounted on the flange for rotatably driving the tape-drum, said flange having a recessed outer surface and said crank handle being mounted for pivotal movement between an actuating position extending outwardly of said outer surface and a stored position within said recess; the combination comprising an elongated groove in the inner surface of the flange juxtaposed the recess on the outer surface and having a central through aperture communicating with the recess, a first shaft mounted in said elongated groove and extending across said through aperture, said first shaft providing a pivot for movement of said handle between said actuating and stored positions, a second handle mounting shaft connected to said first shaft and extending outwardly through said aperture, said second shaft mounting the crank handle for rotary and axial movement relative thereto, and spring means mounted within the handle and cooperating with the second shaft for constantly biasiNg said handle toward said first shaft in both said actuating and stored positions.
Claim 2
Dependent Claim
179 words
In a tape measure including a rotatable tape-drum having a rotary flange and a crank handle eccentrically mounted on the flange for rotatably driving the tape-drum, said flange having a recessed outer surface and said crank handle being mounted for pivotal movement between an actuating position extending outwardly of said outer surface and a stored position within said recess; the combination comprising an elongated groove in the inner surface of the flange juxtaposed the recess on the outer surface and having a central through aperture communicating with the recess, a first shaft mounted in said elongated groove and extending across said through aperture, said first shaft providing a pivot for movement of said handle between said actuating and stored positions, a second handle mounting shaft connected to said first shaft and extending outwardly through said aperture, said second shaft mounting the crank handle for rotary and axial movement relative thereto, and spring means mounted within the handle and cooperating with the second shaft for constantly biasiNg said handle toward said first shaft in both said actuating and stored positions.
Claim 3
Dependent Claim
18 words
Device according to claim 1, in which said drum and said flange are made in a single piece.
Claim 4
Dependent Claim
92 words
The device of claim 1, wherein said crank handle has a central bore slidably receiving said second shaft, said central bore having an enlarged cylindrical portion and a reduced end portion jointly defining an interior shoulder, said second shaft having a radially protruding abutment mounted in said enlarged cylindrical portion of the bore, and said spring means consisting of a compression spring disposed in said enlarged portion of the bore and acting against said abutment of said second shaft and said interior shoulder to bias said crank handle toward said first shaft.
Claim 5
Dependent Claim
66 words
The device of claim 1, wherein said first shaft is comprised of an enlarged central portion and two cylindrical coaxial side parts projecting from opposite sides of the central portion, said side parts being journaled in said elongated groove, said central portion having a flat face and said second shaft protruding from said flat face perpendicular to the axis of said side parts and said groove.
Claim 6
Dependent Claim
25 words
Device according to claim 4, in which said two cylindrical parts and said central portion of said first shaft are made in a single piece.
Claim 7
Dependent Claim
114 words
The device of claim 4, wherein one end of the crank handle is constantly in confronting relationship with said flat face of said central portion, said recess is provided with a shoulder against which the crank handle bears under the action of said spring means when the handle is in the stored position, said shoulder being spaced from said aperture, said one end of the crank handle bearing against said flat face of the central portion of said first shaft under the action of the spring means when the crank handle is in its actuating position and being held out of contact therewith by said shoulder when the handle is in its stored position.
Claim 8
Dependent Claim
69 words
The device of claim 1, including stop means for limiting pivoting movement of said second shaft about said first shaft between said actuating and stored postions to a movement of 90*, said stop means including a lower surface of said recess adapted to support said crank handle in said stored position and an end surface of said recess adapted to abut against said crank handle in said actuating position.
