Abstract
Abstract In a turntable fabric spreading machine having a positive drive roller for drawing fabric off a supply roll and positively feeding it through a cutting assembly to a table surface, handleactuated cam means mounts an idler roller for movement between an operative position in which it is in close promimity to the positive feed roller for causing the fabric to wrap around the latter, and a retracted position in which it is spaced a substantial distance from the feed roller to permit the fabric to be manually fed therebetween. Handle-actuated cam means are also provided to separate the front wall of the cutting assembly housing from a guard plate normally closely spaced from said front wall, in order to permit fabric to be manually fed between said front wall and guard plate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
282 words
In a fabric spreading machine including a carriage movable back and forth over a table surface and having means for mounting a supply of fabric thereon, a cutting assembly having a housing, and a positive drive roller rotatable in a single direction in response to movement of the carriage over the table surface in either direction, the improvement comprising a cam-operated fabric feeding assembly for guiding said fabric about said positive drive roller and through said cutting assembly and being movable to a retracted position to permit said fabric to be fed around said roller and through said cutting assembly, said fabric feeding assembly including an idler roller, movable support means mounted on said carriage and carrying said idler roller, manually operable drive means for moving said support means, and first cam means engaging said support means and guiding the same for movement of said idler roller between an operative position closely spaced from one side of said positive drive roller, and a retracted position spaced a substantial distance from the other side of said positive drive roller for feeding fabric between said rollers, said first cam means being adapted to hold said idler roller immoveably in said operative position, a movable front wall on said cutting assembly housing, a guard plate mounted adjacent said front wall and being closely spaced therefrom for guiding fabric therebetween, and second cam means movably mounted on saId carriage and coupled to said movable front wall for spreading apart said front wall and guard plate a sufficient distance to permit the leading edge of the fabric passing around said positive feed roller to be fed between said front wall and guard plate to said table surface.
Claim 2
Dependent Claim
282 words
In a fabric spreading machine including a carriage movable back and forth over a table surface and having means for mounting a supply of fabric thereon, a cutting assembly having a housing, and a positive drive roller rotatable in a single direction in response to movement of the carriage over the table surface in either direction, the improvement comprising a cam-operated fabric feeding assembly for guiding said fabric about said positive drive roller and through said cutting assembly and being movable to a retracted position to permit said fabric to be fed around said roller and through said cutting assembly, said fabric feeding assembly including an idler roller, movable support means mounted on said carriage and carrying said idler roller, manually operable drive means for moving said support means, and first cam means engaging said support means and guiding the same for movement of said idler roller between an operative position closely spaced from one side of said positive drive roller, and a retracted position spaced a substantial distance from the other side of said positive drive roller for feeding fabric between said rollers, said first cam means being adapted to hold said idler roller immoveably in said operative position, a movable front wall on said cutting assembly housing, a guard plate mounted adjacent said front wall and being closely spaced therefrom for guiding fabric therebetween, and second cam means movably mounted on saId carriage and coupled to said movable front wall for spreading apart said front wall and guard plate a sufficient distance to permit the leading edge of the fabric passing around said positive feed roller to be fed between said front wall and guard plate to said table surface.
Claim 3
Dependent Claim
87 words
A fabric feeding assembly according to claim 1 in which said movable support means comprises a pair of spaced elongated arms carrying said idler roller therebetween at the front end thereof, and said first cam means comprises a cam slot on said carriage, and cam followers on at least one of said arms in engagement with said cam slot, said manually operable drive means being connected to one of said arms for moving said arms in a direction in which said cam followers move through said slot.
Claim 4
Dependent Claim
45 words
A fabric feeding assembly according to claim 2 in which said drive means comprises a rotatable operating handle, a lever coupled to said handle, and a connecting link connected at one end to said lever and at the other end to one of said arms.
Claim 5
Dependent Claim
49 words
A fabric feeding assembly according to claim 3 in which said cam slot and drive means are arranged to move said arms in a compound movement in which said idler roller is raised above the level of said positive feed roller and is then moved forwardly of the latter.
Claim 6
Dependent Claim
77 words
A fabric feeding assembly according to claim 1 in which said cutting assembly housing has a bottom wall, a top wall, a rear wall and a pair of end walls, said movable front wall being mounted below the forward end of said top wall and being normally perpendicular thereto, said guard plate being pivotally mounted at its bottom end forwardly of said bottom wall and being normally parallel to and closely spaced forwardly of said front wall.
Claim 7
Dependent Claim
95 words
A fabric feeding assembly according to claim 5 in which said second cam means includes a pair of cam discs rotatably mounted in the respective end walls of said housing, a shaft eccentrically mounted in said cam discs and extending transversely therebetween, an operating handle mounted outside said housing and coupled to said shaft for rotation of the latter when said handle is turned, and a cam follower mounted on said front wall and engaging said shaft for moving said front wall in a direction away from said guard plate when said handle is turned.
Claim 8
Dependent Claim
37 words
A fabric feeding assembly according to claim 6 in which said front wall has a guide rod secured thereto, said guide rod extending rearwardly through said housing and projecting through an aperture in the rear wall thereof.
Claim 9
Dependent Claim
45 words
A fabric feeding assembly according to claim 6 in which said second cam means also includes a lever arm coupled to said operating handle, and an angular link connected at one end to said lever arm and at the other end to said guard plate.
Claim 10
Dependent Claim
48 words
A fabric feeding assembly according to claim 8 in which turning movement of said operating handle turns said lever arm in a direction to cause said angular link to move forwardly and move said guard plate about its pivotal mount in a direction way from said front wall.
