In operation,` the upholstery finish material 14 is folded as at 27 and the fold is pressed f back cover sheet 14, and as the flare'of the flange 21 increases toward the rear, the padding aswell as the cover sheet 14 will be depressed as shown in Fig. 9, opposite the needle so as to prevent any interference therewith. |The flange 22 will operatey similarly on the cover sheet 11, and as the flare Vthereof increases toward the heel of the guide, the padding and cover 11 will be depressed to about the shape shown in Fig. 9. At the saine time, the fold 27 will engage the Y inner side of the flange 23 under the bottom portion 15 and so thevflange will act as a gauge for the stitching by the needle 25. In other Words, the stitching and the fold of the cover sheet will be gauged by the flange 23 so that this line of stitching will be parallel to the line of stitching 12. v

When a seam has been vformed Y,as above described, the cover 14 will be pulled over the next rib in the ,padding and folded again to form the next seam. Thus the seam in the cover 14 is a concealed stitch and the fold 27, whenthe cover material is pulled over the next rib, will be depressed into the groove immediately above the stitching 12. VThis arrangement provides a very neat appearing exterior for the completed upholstery.

As shown in Figs. 7 and 8, the flange 23 of Fig. 4 may be substituted by a disc orl wheel 30, pivoted to the body 15 in such a manner as to depend below the body'l substantially the same amount as the flange 23.V The provision of the wheel will eliminate a certain Y co amount of friction and will be more desirable Y for some materials.

Figs. 7 and 8 illustrate a further modification, in that, in lieu of the socket 17, a flat have been illustrated and described in such detail as to enable any one skilled in the art to practice the invention, nevertheless itis to be understood that the invention is not to be limited to the details disclosed, other than as necessitated by the development of the prior art; but, instead, the invention embraces such embodiments'of the broad idea as fall within the scope of the appended claims,

it being obvious that various changes may be made in the disclosed embodiment without de arting from the spirit of the invention.
