Abstract
Abstract The mechanism comprises a plurality of print wheels each capable of adjustment to give a selected print-out and a corresponding plurality of read-out wheels the adjusted positions of which correspond at any given time to those of the print wheels. The print-out of any given print wheel is adjusted by a pinion carried by a screwed member which is constrained to rotate the pinion unless a control knob is moved axially, when a clutch member acts to prevent rotation of the pinion so that the latter tracks along the screwed member until it is opposite another print wheel to be adjusted. Release of the knob to resume its normal axial position enables adjustment of the print wheel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
In an adjustable-facet print mechanism, a plurality of printfacet carriers arranged side-by-side, each said carrier including a plurality of print-facets, adjustment means common to said carriers for adjusting the operative print-facet of a selected one of said carriers, selection means for selecting one of said carriers for adjustment by said adjustment means, said selection means serving to move said adjustment means relative to said carriers to a position wherein said adjustment means can act to adjust a selected carrier, and a single rotatable member common to both said adjustment means and said selection means and constituting the sole actuating member for both thereof, said single rotatable member being selectively axially displaceable between two positions and operable, in one of said positions, to operate only said selection means and, in the other of said positions, to operate only said adjustment means.
Claim 2
Dependent Claim
140 words
In an adjustable-facet print mechanism, a plurality of printfacet carriers arranged side-by-side, each said carrier including a plurality of print-facets, adjustment means common to said carriers for adjusting the operative print-facet of a selected one of said carriers, selection means for selecting one of said carriers for adjustment by said adjustment means, said selection means serving to move said adjustment means relative to said carriers to a position wherein said adjustment means can act to adjust a selected carrier, and a single rotatable member common to both said adjustment means and said selection means and constituting the sole actuating member for both thereof, said single rotatable member being selectively axially displaceable between two positions and operable, in one of said positions, to operate only said selection means and, in the other of said positions, to operate only said adjustment means.
Claim 3
Dependent Claim
17 words
A mechanism according to claim 1 comprising read-out means adjustable in synchronism with adjustment of the carriers.
Claim 4
Dependent Claim
16 words
A mechanism according to claim 1, wherein the means common to said carriers comprises a pinion.
Claim 5
Dependent Claim
249 words
In an adjustable-facet print mechanism, a row of spaced print-facet carriers, each said carrier incorporating a plurality of print-facets, turning means for turning selectively one of said carriers to change the operative print-facet thereof, a screwed member carrying said turning means, said turning means containing matingly screwed means for cooperating with said screwed member, said screwed member, said screwed cooperating means and said turning means constituting means for providing relative angular movement between said screwed member and said turning means, said screwed cooperating means allowing axial displacement of said turning means upon rotation of said screwed member, and operating means coaxial with said screwed member selectively operable to prevent such relative angular movement and thereby rotate said turning means with said screwed member, said coaxial means also acting to provide for said relative angular movement and thereby a rotary input to said screwed member, when the turning means is at a selected position and such relative angular movement is prevented, effects adjustment of the corresponding carrier at the selected position to render a different print-facet operative, said operating means including a single rotatable member displaceable axially between two axially spaced positions in one of which it is operable to provide a rotary input to drive said turning means together with said screwed member to effect adjustment of the selected carrier to render a different print-facet operative and in the other of which it is operable to effect such relative axial movement between said screwed member and said turning means.
Claim 6
Dependent Claim
249 words
In an adjustable-facet print mechanism, a row of spaced print-facet carriers, each said carrier incorporating a plurality of print-facets, turning means for turning selectively one of said carriers to change the operative print-facet thereof, a screwed member carrying said turning means, said turning means containing matingly screwed means for cooperating with said screwed member, said screwed member, said screwed cooperating means and said turning means constituting means for providing relative angular movement between said screwed member and said turning means, said screwed cooperating means allowing axial displacement of said turning means upon rotation of said screwed member, and operating means coaxial with said screwed member selectively operable to prevent such relative angular movement and thereby rotate said turning means with said screwed member, said coaxial means also acting to provide for said relative angular movement and thereby a rotary input to said screwed member, when the turning means is at a selected position and such relative angular movement is prevented, effects adjustment of the corresponding carrier at the selected position to render a different print-facet operative, said operating means including a single rotatable member displaceable axially between two axially spaced positions in one of which it is operable to provide a rotary input to drive said turning means together with said screwed member to effect adjustment of the selected carrier to render a different print-facet operative and in the other of which it is operable to effect such relative axial movement between said screwed member and said turning means.
Claim 7
Dependent Claim
71 words
A mechanism according to claim 4, comprising a casing, and wherein said means for selectively preventing and providing for said relative angular movement comprises a dog clutch including a first half, and a second half, said first half being rotatable wiTh the turning means, the second half being fixed relative to the casing, and axial motion of the single rotatable member between two positions serving to engage and disengage the clutch.
Claim 8
Dependent Claim
19 words
A mechanism according to claim 5, comprising means biasing the first and second halves of said clutch into engagement.
