Method for manufacture of feather quilt
First Claim
1. A method for the manufacture of a feather quilt by the steps of attaching partition pieces to the upper and lower cloth layers of an equal size of a quilt enclosure along longitudinally and laterally spaced lines thereby forming rectangular spaces arrayed in regular rows and files in the interspace between said upper and lower cloth layers of the quilt enclosure and blowing down into said rectangular spaces, which method comprises:
- sewing ribbonlike partition pieces by one edge portion thereof to the inner sides of said upper and lower layers along all the boundaries of said rectangular spaces running in either of the two perpendicularly intersecting directions and sewing T-shaped partition pieces, which comprise a partition portion and a projecting portion protruding in one direction from the central portion of said partition portion, by one edge portion of said partition portion to said inner sides along all the boundaries of said rectangular spaces running in the other of said intersecting directions,sewing the corresponding ribbonlike partition pieces of the upper and lower layers together along the other edge portion thereof and, at the same time, sewing the corresponding T-shaped partition pieces of the upper and lower layers together along the other edge portion of said partition portion except for the portion from which said T-shaped projecting portion protrudes, superposing the end portions of said ribbonlike partition pieces and said T-shaped partition pieces both fastened to the upper and lower layers, and sewing the superposed end portions together,superposing said T-shaped partition pieces fastened to said upper and lower layers and sewing the opposite lateral sides of said projecting portions of said T-shaped partition pieces thereby forming openings along the edges of said projecting portions, andinserting a down injection tube through said openings formed of said T-shaped projecting portions in lateral sides of said rectangular spaces and blowing the down sequentially into the interiors of said rectangular spaces.

Abstract
A feather quilt comprising upper and lower cloth layers, a multiplicity of rectangular spaces arrayed in regular rows and files in the interspace between the upper and the lower layer, and down placed to fill up the rectangular spaces is manufactured by sewing ribbon-like partition pieces to the inner sides of the upper and lower layers along the individual boundaries of the rectangular spaces running in the longitudinal (or lateral) direction and T-shaped partition pieces to the aforementioned inner sides along the individual boundaries of the rectangular spaces running in the lateral (or longitudinal) direction, sewing together the corresponding ribbonlike partition pieces fastened to the upper and lower layers, similarly sewing the T-shaped partition pieces together with the exception of the openings formed of the projecting portions thereof, and sequentially filling with down the rectangular spaces formed between the upper and lower layers by the use of a down injection tube inserted through the openings into the interiors of the successive rectangular spaces. By this method, a feather quilt of any desired thickness can be easily and efficiently manufactured without reference to the diameter of the down injection tube used for the transfer of the down.
