PRESSER FOOT Filed Jan. 25, 1927 2\ Sheets-Sheet 2 Patented Oct. 29, 1929 UNETED STATES WILLIS S. SHAFT, OF FARIBAULT, MINNESOTA, A'SSIGNOR,TO'SI-I-AFTPIER/CE SHOE COM- VPANY, OF FARIBA-ET, MINNESOTA PRESSER FOOT Application led January 25, 1927. Serial No. 163,493.
This invention appertains to a trimming machine and more particularly to ay novel attachment for trimming machines of the type known in the art as a top stitcher and trimmer and to be used in lieu of certain stitching parts thereon, whereby the machine can be effectively used for trimming the soles of shoes.
The primary object of the present invention is the provision of a novel presser foot for association with a trimming machine in lieu of the usual roller guide, the presser foot forming means for acting as a guide for allowing the upper and middle sole to be cut uniformly, thereby eliminating the rough rounding process now necessary inI stitch down types of shoes.
A further object of the invention is the provision of novel means for accurately trim. ming shoes on a top stitcher and trimmer in which the usual needle and roller guide is eliminated and a novel combined presser foot and guide substituted therefor, the guide forming means by which the upper can be guided and gauged during the trimming of the upper and the middle sole of the shoe.
A further object of the invention is the provision of a novel presser foot and shoe guide for use in shoe trimming, whereby the upper will be properly spaced from the cutting knife and whereby the manipulation of the shoe on the post bed of the shoe will be facilitated.
l/Vit-h these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:
Figure 1 is a side elevation of a shoe trimmer showing Vthe improved presser foot incorporated therewith, Y
Figure 2 is a fragmentary front elevation of the same showing a shoe in dotted lines being trimmed,
Figure 3 is a horizontal section taken on the line 3 3 of Figure 2 looking in the direction of the arrows showing the shoe in dotted site side of the slice 'showing' the relative' position of the cutting knife, presser foot and work post, K Figure 5 is a perspective foot, t
Figure 6 is a perspective view ofthepresser f'ootl'ooking' from the opposite side 4of Figure Figure 7 isa .detail section `taken `on the line 7-7 of Figure 4; looking inthedirection. of the arrows, illustrating the means of connecting the presser .foot with the usual guide roller supporting bar.
Referring to the drawings infdetail, lwherein similar reference charactersdesignateAcorijespending parts throughout the jseveral views., the letter A generally indicates a shoe trimming machine and stitcher such as the type manufactured by the Singer Sewing Machine Co. style 51, W. 55. This machine is of the conventional construction and comprises the usual post head 10 and vert-ical trimming knife 11.` The post bed plate is provided with the usual guide bars 12 for the view of 'the presser trimmer knife 11, and feeder 13 for the work.
In accordance with this invention the usual roller .guide and needle is removed and the and the extension on the middle sole of a shoe constructed in accordance with the stitch down process can be readily trimmed.
The improved presser foot B comprises a flat vertical attaching shank 15 having openings 16 therein whereby the shank can be attached tothe bar 14 bythe use of attaching elements 17. Extending downwardly and inwardly at an angle tothe shank 15 is the inclined arm 18 having formed on its lowerend and laterally thereof a foot proper 19. This foot is of a substantial arcuate configuration lin side elevation and is provided with an inturned free end 20. The arm 18 at its inner end adjacent to the arcuate foot proper 19 is beveled as at 21 so as to form a guide face. This guide face is disposed laterally of the foot proper and is so positioned as to form means for guiding'thecut leather downwardly and away from the knifev and the face of the operator should the cut leather ree tend to ruck upward incidentto the rapid operation of the knife.
In use vof the device the shoe is placed on the post bed under the knife with the upper in engagement with the Varcuate portion 19 5 of the foot. The shoe is now guided around the knife on the post plate by holding the upper against the foot 19. This allows the knife to trim the upper and the extension on the'middle sole uniformly without any difficulty on the part of the operator.
Changes in details may be made without l departing from the spirit or the scope of this invention, but: y i l What I claim as new is:
A presser foot attachment for top stitcher and trimming machines comprising a flat vertical attaching shank, a downwardly and for- WardlyV inclined arm formed on the lower end of the shank, a foot proper formed on the lower end of the karm and extending forwardly therefrom, said foot proper being of v substantially arcuate shape in side elevation and including a relatively short portion hav- ,5 ing its forward leading edge beveled upwardly, and a relatively long portion extending laterally of the short portion `and forwardly thereof, the leading edge of the shortportion terminating in the same plane as the top face 30, of the long portion.
f In testimony whereof I aix my signature. WILLIS S. SHAFT.
