which is especially adapted for tipping shoes.

An object of the invention is to provide means for supporting the guide whereby the same may be shifted laterally to predetermined guiding positions.

A. "further object of the invention is to provide a guide of the above character with means whereby the guide may be shifted on .its support for varying the set positions of the guide relative to the needle or needles of the stitching mechanism.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

In the drawings, which show by way of illustration, one embodiment of the invention:-

Figure 1, is a view partly in front elevation and partly in section, showing a portion of a sewing machine having my improved presser foot applied thereto;

Fig. 2 is a perspectiveview of the presser foot detached from the machine; 7

Fig. 3 is a view partly in plan and partly in section of the same;

-Fig.-' 4 is a vertical sectional view through the presser foot in line with one of the needle openings;

Fig. 5 1s a vertical sectional view taken transversely through the presser foot,

Fig. 6 isaview showing the presser foot in Ian and showing a shoe tip being at t cl fed to the vamp, the guide'being set for directing the tip so as to form the lines of stitching adjacent the edge of the tip;

Fig. 7 is a similar view showing the guide positioned for forming the lines of stitch-- ing at the outer side of the perforations in Fig. 8 is a sectional view througha portlon of 21.131]? and a vamp, showing diagrammatically stitching; I

Fig. 9 is a view showing a portion of a vam and a tip-attachedthereto; and

Fig. '10 is a bottom ser'foot.

the position 'of the lines of It is well known that the tips of shoes' are often ornamented by forming a series of openingstherethrough adjacent the edge of the tip which is' secured to the vamp.-

This edge is secured to the vamp by one or two lines of stitches which pass through the tip and the vamp on opposite sides of the series of openings. This "is known in the art as a tipping operation.

In order that the finished shoe may have the properappearance, it is essential that these lines of stitches should be disposed an equal distance from the outer edges of the perforations or openings in the-tip.-

The present invention has to do with'the guide for guiding the tip so as to pro erly position the lines of stitches referre to.

plan view of the pres- 7 This guide is mounted on the support which is movable so as to shift the guide laterally relative to the needle and this support is held yieldingly in predetermined positions relative to the needles. The guide itself is adjustably attached to the support so that it may be 'adjusted'relative to the set positions of the 7 support. This permits the guide to be not only shifted but adjusted and a proper positioning of the tip for placing the lines of stitching relative to the'perforationsin the tip and also relative to the edge of the tip so that the finished article shall be properly constructed.

Referring more in detail to the drawings, I have shown my improved presser footl, as applied toza sewing machine having a needle bar 2 carrying two needles 3 and 4. There is' alooper -5 whichcooperates with the needle 3 and a looper 6 which cooperates with the needle 4. The needles and the loopers may be operated'in' any welli'k'nown manner.

The presser foot 1 1s carried by a presser bar7. Said presser foot comprisesa shank 8 which is-clamped to the presser bar 7 and a foot section 9 is pivotally secured by a Mounted on the presser foot 9 is an edge guide 11. Said edge guide 11 is fixed to a shank12whiohslides .in a groove13 in the presser foot 9. The edge guideis provided with a section 14: which extends underneath the presser foot and the 'inner edge'15 of this section 14 isthe guide proper which engagesthe edge of the tip and directs the same to the needles. The edge guide 11 has an upwardly extending forked standard 16.

This standard is threaded to engage a threadedadjusting screw 17. The adjustingv ingly, hold thesupport .in vtwo different set.

Positi n The shaping of the end of'the pin and therecesses is such that a pressure endwise of the support will move said support inthe guide way and shift the same.

from. one set-position to the other. On the end of thegsupport 18 is a cap24 which limits the movement ,of the support if it is moved. beyond the point where the-pin 23 engages thenotch 21.

In F'gs. 8 and 9 .of, the drawings, Lhave shown a shoe vamp indicated at V1110 which a tipisfattached, indicated at T; This tip is provided witha row. of openings or per-' forations p which extend in a direction parallel with the edge 25 of the tip.T. I have alsoshown inthese figures a tipesecured to the vamp by two lines of stitching 8 locatedat,one side of thevopenings or perforations ,and two' lines of stitching 8" located. the otherside of theopenings or perforations p.

In the operation. of .my' device the edgev guide may beset as shown in Fig. .6, that is, with. the pin 23 engaging .the notch 20.

.Thisjis one 'set position forthe support .18

p and :when so positioned the vamp. indicated at.V:and the tip indicated at T in Fig. 6

maybe guided to the presser foot. sothat.

the edge 25 of the tip T willbe in engage- .ment.withthe guiding edge 15 .of my-.im-

proved; guide 11;-1 This will position the lines-ofstitching. s so, that they will 'bebetween the perforations andthe edge ofIthev tip iand,jof-.z:course, parallel with the edge] of;the".tip., f r I Y P After. thisline of .stitching has been formediconneoting thetip to the vamp, then the guide is shifted to the position shown.

incFigL'T This maybe done by. pressing on thecap QLwhich causes the pin 23 to rise out of the recess '20 and engage the recess 21.-

When thus positionedthe" line of' stitching siwi'll'ibe formed and thisline of stitching will beiparallel with the edge 25- of the tip;

and located on the opposite sides of the'perforations or openings 79. The presser foot is provided with openings 26 and 27 and the opening% is for the needle 3 and th'e opening27 for the needle #1. It sometimes happens that the openings orperforations in the tip of the shoe vary 1 slightly in their distance from the edge o f the tip. By turning the adjustingsc rew17, the positionof the guide relative to the sup 7 port may be changed, and the guide may be shifted from one predetermined;setpositiorn to another predetermined set position relative to the needle openings. Thiswillshift.

the guide laterally from one predetermined set position to anotherpredetermined set; position. By turning the screw 17 the set; positions'of the guide inay-be. varied al; though the setpositionsof the SUPPOBRIB are fixed. Therefore, the distanc betweenj one setposition andthe other will: ;-remain-;;

the. sameunless the screw 17 istu-rned and if the distance ofthe .perforationsor openings p from the edge ofithe tip bejncjreased. then by turning the screw-17 'thesetgposi tions may be shifted backfromthe edgeof the tipso thatjhe openings or perforations.

p will be centered between the lines of stiteh mg. g

It also sometimes happensthat the open ings or perforations will vary..- slightly in v size. Under theseconditions thefirst line-ofv stitching 8 may be placed -,betwe6ni the -per- .forations or; openings 29 and-theedge ofthe tip, thenthe guideshifted-forpositioning th ti for thefline of stitching s andthe screw 17 turned. sufficiently; so as to, center the perforations or openings between .the lines. of stitching. This, injother words, shifts the. set positions of .the guide;so ;tl1at. the distance between the same may be- .either; slightly greater .or, slightly less-as desired 7 although the distance between, the. .set-posi-s tions of the support 18 remains fixed. l

Iti'is obvious that, minor changes. jinithe details of construction may be, made without g departing from. the spirit of, the inventiQI as set forth in theappendedrclaims.
