Abstract
Abstract A fabric marking device for producing a powder mark of predetermined shape and size on pieces of fabric. The device comprises a table with a perforated work surface area and means for delivering powder under air pressure to one or more tubes having a lengthwise slit therein which is placed against a surface of fabric to be marked. Means are provided for altering the angle of the tubes relative to each other, and/or to the fabric to be marked, and for varying the distance between the tubes and work surface to accommodate marking a stack of fabric layers simultaneously.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
231 words
A fabric marking device comprising: A. a frame having a work surface including an area perforated therethrough; means for depositing a marking powder on at least one predetermined line simultaneously through multiple layers of fabric positioned on said perforated area, thereby leaving a distinct and accurate indicia on both sides of the fabric layers; B. said means including at least one tubular member having a lengthwise slit through the wall thereof, and connected to a source of marking powder emitable through said slit under sufficient pressure for the powder to pass through said layers; C. said tubular member, or members, being controllably positioned with the slit thereof ready for contact with a fabric layer positioned on said perforated area; D. a marking powder container; E. means for delivering marking powder from said container to a mixing valve whereby said mixing valve accepts a predetermined quantity of marking powder; F. means for delivering air under pressure to said valve, said valve being provided with means whereby said delivery of pressurized air interrupts said marking powder delivery means, said predetermined quantity of marking powder is mixed with said pressurized air for deposit on said fabric layers, and said marking powder delivery means are reactivated to provide subsequent delivery of a predetermined quantity of marking powder when said air delivery means are deactivated; G. conduit means connecting said tube, or tubes, to said valve.
Claim 2
Dependent Claim

A fabric marking device comprising: A. a frame having a work surface including an area perforated therethrough; means for depositing a marking powder on at least one predetermined line simultaneously through multiple layers of fabric positioned on said perforated area, thereby leaving a distinct and accurate indicia on both sides of the fabric layers; B. said means including at least one tubular member having a lengthwise slit through the wall thereof, and connected to a source of marking powder emitable through said slit under sufficient pressure for the powder to pass through said layers; C. said tubular member, or members, being controllably positioned with the slit thereof ready for contact with a fabric layer positioned on said perforated area; D. a marking powder container; E. means for delivering marking powder from said container to a mixing valve whereby said mixing valve accepts a predetermined quantity of marking powder; F. means for delivering air under pressure to said valve, said valve being provided with means whereby said delivery of pressurized air interrupts said marking powder delivery means, said predetermined quantity of marking powder is mixed with said pressurized air for deposit on said fabric layers, and said marking powder delivery means are reactivated to provide subsequent delivery of a predetermined quantity of marking powder when said air delivery means are deactivated; G. conduit means connecting said tube, or tubes, to said valve.
Claim 3
Dependent Claim
14 words
The device of claim 1 including means for changing the length of said slit.
Claim 4
Dependent Claim
14 words
The device of claim 2 including powder-collecting means positioned below the said perforated area.
Claim 5
Dependent Claim
16 words
The device of claim 3 wherein the said depositing means comprises at least two spaced-apart tubes.
Claim 6
Dependent Claim
92 words
The device of claim 4 wherein said depositing means comprises a member hinged to said frame, said member having an open position and a closed position, said member being in its closed position when it is closest to said work surface; spring means for urging said member to its open position; a locking device for maintaining said member in its closed position; means for varying the distance between said tubes and said work surface; and means for positioning said tubes at a predetermined angle in a plane parallel to said work surface.
