Abstract
Abstract Aparatus for determining whether an imperfection in fabric will lie within or without a pattern to be cut out from the fabric while the fabric is being laid out on a cutting table by means of a carriage for a supply of the fabric to be laid out which also carries a replica of the pattern to be cut and means to move the replica to correspond with the laying out of the fabric and indicia means to correlate the positions of imperfections in the cloth with the replica of the pattern to be cut.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
Apparatus for laying out a plurality of layers of cloth on an elongated cutting table, comprising carriage means reciprocatorily movable along the length of a cutting table, said carriage means including means to support a supply of cloth to be laid out on a table during said reciprocatory movement, pattern means reproducing the outlines and relative positions of pieces of cloth to be cut out when the layers of cloth are in position on a table, and correlation means to continuously disclose the relative position of an imperfection in the cloth with respect to the outlines of pieces of cloth to be cut out, said pattern means including two elements, one of said two elements comprising a sheet bearing outlines of the pieces of cloth to be cut out, the other of said two elements comprising indicia means disposed to coact with said sheet, and said correlation means including means to move one of said two elements continuously with respect to the other of the two elements in synchronism with movement of the carriage means during laying out of said fabric.
Claim 2
Dependent Claim
181 words
Apparatus for laying out a plurality of layers of cloth on an elongated cutting table, comprising carriage means reciprocatorily movable along the length of a cutting table, said carriage means including means to support a supply of cloth to be laid out on a table during said reciprocatory movement, pattern means reproducing the outlines and relative positions of pieces of cloth to be cut out when the layers of cloth are in position on a table, and correlation means to continuously disclose the relative position of an imperfection in the cloth with respect to the outlines of pieces of cloth to be cut out, said pattern means including two elements, one of said two elements comprising a sheet bearing outlines of the pieces of cloth to be cut out, the other of said two elements comprising indicia means disposed to coact with said sheet, and said correlation means including means to move one of said two elements continuously with respect to the other of the two elements in synchronism with movement of the carriage means during laying out of said fabric.
Claim 3
Dependent Claim
28 words
The apparatus as defined in claim 1, wherein the scale of the pattern means is the same as that of the pieces of cloth to be cut out.
Claim 4
Dependent Claim
30 words
The apparatus as defined in claim 1, wherein the scale of the pattern means is reduced with respect to the scale of the pieces of cloth to be cut out.
Claim 5
Dependent Claim
17 words
The apparatus as defined in claim 1, wherein said sheet comprises a transparent image of said outlines.
Claim 6
Dependent Claim
42 words
The apparatus as defined in claim 1, wherein one of said two elements of the pattern means comprises a visual representation of said outlines and the other of said two elements comprises scale means positioned for visual comparison with said one element.
Claim 7
Dependent Claim
45 words
The apparatus as defined in claim 5, wherein said visual representation is embodied in a sheet, and said pattern means includes means to mount said sheet on the carriage means for movement with respect to the scale means corresponding to movement of the carriage means.
Claim 8
Dependent Claim
36 words
The apparatus as defined in claim 6, wherein said carriage means includes means to feed cloth to a cutting table in response to movement of the carriage means, said last named means including reversing clutch means.
Claim 9
Dependent Claim
91 words
The apparatus as defined in claim 6, wherein said visual representation includes an endless sheet of material, and a pair of rotatably mounted support rollers for said sheet, said carriage means including a supporting wheel in contact with a cutting table, driving means connecting said supporting wheel with one of said rollers, scale means positioned adjacent said sheet, and corresponding scale means adjacent the cloth being fed to a table, both said scale means extending transversely with respect to the direction of movement of the elements with which they are associated.
Claim 10
Dependent Claim
70 words
The apparatus as defined in claim 8, wherein said driving means includes belt means connecting said supporting wheel with said one roller, and also includes belt means and winding off roller means for feeding cloth to a table in response to movement of the carriage means, said last named belt means including reversing clutch means to permit cloth to be fed in either direction of movement of the carriage means.
