Abstract
Abstract A taker-in under casing in a carding machine is disposed below a taker-in roller and between an under casing for a cylinder and a dish plate so as to extend along a portion of the lower peripheral surface of the taker-in roller. In order to vary the spacing between the taker-in under casing and the dish plate and/or the gauge between the taker-in under casing and the taker-in roller to thereby control the quantity and a quality of substances to be removed at the taker-in under casing, the latter is provided with a device for adjusting the position of the taker-in under casing, which is manually operable at the outside of the carding machine. The adjusting device has a first adjusting mechanism for causing the taker-in under casing to slide along the circumference of the taker-in roller, and a second adjusting mechanism for causing the taker-in under casing to pivot toward and away from the taker-in roller, these mechanisms being operable independently of each other.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
197 words
A carding machine which comprises: a. a taker-in roller for stripping and feeding a lap; b. a dish plate and cooperating feed roller positioned on the lap feed side of said taker-in roller; c. a taker-in under casing below said taker-in roller and on the downstream side of said taker-in roller relative to said dish plate, said under casing comprising a movable half disposed on the upstream side with respect to the movement of the lap, and a stationary half disposed on the downstream side with respect to the movement of the lap; d. supporting means pivotally supported on said machine and supporting said movable half for turning movement around the pivotal support of said supporting means and circumferential movement along a portion of the circumference of said taker-in roller; e. a first adjusting means associated with said movable half for causing said movable half to turn around the pivotal support point of said supporting means; and f. a second adjusting means associated with said movable half for causing said movable half to move circumferentially along the portion of the circumference of said taker-in roller, said second adjustable means being operable independently of said first adjusting means.
Claim 2
Dependent Claim
197 words
A carding machine which comprises: a. a taker-in roller for stripping and feeding a lap; b. a dish plate and cooperating feed roller positioned on the lap feed side of said taker-in roller; c. a taker-in under casing below said taker-in roller and on the downstream side of said taker-in roller relative to said dish plate, said under casing comprising a movable half disposed on the upstream side with respect to the movement of the lap, and a stationary half disposed on the downstream side with respect to the movement of the lap; d. supporting means pivotally supported on said machine and supporting said movable half for turning movement around the pivotal support of said supporting means and circumferential movement along a portion of the circumference of said taker-in roller; e. a first adjusting means associated with said movable half for causing said movable half to turn around the pivotal support point of said supporting means; and f. a second adjusting means associated with said movable half for causing said movable half to move circumferentially along the portion of the circumference of said taker-in roller, said second adjustable means being operable independently of said first adjusting means.
Claim 3
Dependent Claim
20 words
The carding machine as claimed in claim 1, wherein said supporting means supports said movable half for sliding movement therealong.
Claim 4
Dependent Claim
64 words
The carding machine as claimed in claim 1, wherein said supporting means comprises a plate member at each end of said movable half and pivotably connected to a portion of said stationary half and supporting said movable half in load bearing relationship, and a supporting shaft extending substantially in parallel with said movable half and supporting said plate members in load bearing relationship therewith.
Claim 5
Dependent Claim
37 words
A carding machine as claimed in claim 3, wherein said movable half has an extension thereon partially overlapping said stationary half, said movable half being movably mounted on said plate member for movement toward said taker-in roller.
Claim 6
Dependent Claim
24 words
The carding machine as claimed in claim 3, wherein said supporting shaft has a portion supported by and extending outward of said carding machine.
Claim 7
Dependent Claim
116 words
A carding machine as claimed in claim 5, wherein said first adjusting mechanism comprises a control lever arranged outward of said carding machine, a shaft member connected to said control lever and movably supported by said carding machine and first motion transmitting means connected between said shaft member and said movable half to transmit the motion of said shaft member to said movable half when said control lever is operated; and said second adjusting mechanism comprises a further control lever connected to the outwardly projecting portion of said supporting shaft, and second motion transmitting means arranged between said supporting shaft and said plate members to transmit the motion of said supporting shaft to said plate members.
Claim 8
Dependent Claim
33 words
A carding machine as claimed in claim 6, wherein said first and second adjusting mechanisms comprise respectively first and second means for locking said first and second control levers into respective controlled positions.
Claim 9
Dependent Claim
77 words
A carding machine as claimed in claim 6, wherein said first motion transmitting means comprises a bifurcated member fixed to said shaft member, a pin extending from one end of said movable half and engaged in said bifurcated member, and a pin and slot assembly provided between one of said plate members and said movable half to allow said movable half to move toward and away from said dish plate when said first control lever is operated.
Claim 10
Dependent Claim
30 words
A carding machine as claimed in claim 8, wherein said second motion transmitting means comprises a cam means having a surface engaging said one plate member with the pivotal motion.
Claim 11
Dependent Claim
72 words
A carding machine as claimed in claim 8, wherein said first motion transmitting means comprises a bifurcated member fixed to said shaft member, a pin extending from one end of said movable half and engaged in said bifurcated member, and guide pins extending from one end of said movable half and said movable half being guided between and supported by said guide pins for movement toward and away from said dish plate.
Claim 12
Dependent Claim
69 words
A carding machine as claimed in claim 10, wherein said second motion transmitting means comprises a bifurcated member fixed to the projecting portion of said supporting shaft, and a pin extending from a free end portion of one of said plate member and engaged in said bifurcated members of said second motion transmitting means whereby said plate member makes the pivotal motion when said second control lever is operated.
