WELT SEWING ATTACHMENT Filed Dec; 18, 1957 INVENTOR. JOSEPH L EPA-VH5 ATTORNEYS Patented Aug. 8, 1939 UNITED STATES PATENT OFFICE 4 Claims.
This-invention-relates to improvements ina W wing attachment for a shoe machine, and more particularly to an attachment for a- McKay stitching machine for sewing a welt to the upper and insole of a shoe after the lasting operation.
It is an object of my invention to provide an attachment for a McKay stitcher or other straight needle machine which may be readily attached to'the machine, and which will provide an adlustable welt guide and an adjustable upper uide. r a
It is further-Tan object of my invention to provide an attachment in which the upper guide is shaped to permit sewing of the welt nearer to the middle of the shoe at the shank portion than at the forepart of the shoe, as is desirable.
A still further object of my invention resides in the pivotal, adjustable mounting of the upper guide and the vprovision of a rotatable guide wheel which may be swung entirely out of the way for: purposes of repairing the welt.
Further objects and advantages filmy improvements will be more readily apparent from the following detail description of a preferred embodiment'thereof. as illustrated in the attached drawing in which:
'Fig. 1 is a perspective view of the'attachment;
Fig. 2 is a front elevation of the attachment;
Fig. 3 is a plan view of the attachment, and
Fig. 4: is a-front elevation of. the attachment as attaching-portion 8| will be out of the way of the well; which passes through the welt guide in vertical section the welt and the shoe to which the welt is being sewed.
The attachment bracket frame indicated I0 is provided with a welt-guiding channel II, the width of which is adjustable by the welt guide ll secured in'place by the screws l6 receivedin 'the slotted openings II. The shoe upper is guided by the rotatable guide wheel 20 which is mounted for rotation on the bracket arm 22 pivotally sup- "from the pin 28 to move the guide wheel 20 enif ly out of the way in order to repair the welt.
The bracket frame l0 includes a rearwardly directed attaching portion 30 having a slot 32,'
said attaching portion ll being bent upwardly at an angle to the front portion in order thatthe As shown in Fig. 1, the frame II is provided with a slotted opening at which extends.
for a short distance into the welt guide channel to permit movement of the needle through the welt while it is supported by the sides of the channel.
The use of the attachment is illustrated in Fig. 4 in which the bracket isshown mounted on a 5 stitching machine 35 having a straight needle 38. The welt 40 is fed by any suitable feeding means through the welt guide channel l2. The upper 42 of the shoe has lasting margins 44 which have been temporarily tacked to the insole 46,; The 10 shoe is brought into position by the operator so that the welt is sewed to the shoe through the margin 44 of the upper and through the marginal edge of the insole 46. The shoe is held by the operator and guided by the wheel 20. The guide 15 vwheel Zllis of special construction and is formed at its top portion with a relatively narrow straight edge .48 and a wider beveled portion at the bottom. This construction is provided in order to enable the operator to properly sew the welt to go the shoe through the shank portion thereof. It will be apparent that if the guide wheel were of the same uniform width that the shape of the upper at the shank portion would cause the welt to be sewed too far out.
Various changes may be made in the specific form of the attachment without departing from the spirit of my invention as expressed in the appended claims.
I claim:
1. An attachment'for a straight needle shoe stitching machine for stitching a welt to the upper and insole of a shoe after lasting, comprising a bracket frame adapted to be fixed to the shoe stitching machine, a welt-receiving channel in 35 said frame, adjustable means cooperating with said channel for different widths of welt, a bracket arm adjustably mounted on the under side of said frame, and a guide wheel rotatably carried by said arm',said guide wheel having a straight top portion and a beveled bottom portion adapted to engage the shank portion of the shoe while the welt is being stitched thereto, said bracket arm being adjustably mounted on the bracket frame whereby the guide wheel carried by said 5 arm is adjustable in position with respect to the welt channel. Y
i 2. An attachment for a straight needle shoe stitching-machine for stitching a welt to. the up-' per andiinsole of a shoe after-lasting, compris- 50 ing a bracket frame adapted to be fixed to a shoe stitching machine, means for guiding the welt through said frame, a bracket arm, pivotal means foradjustably securing said bracket. arm to said frame, a stop pin mounted in said frame for limiting pivotal movement of said bracket arm in one direction, said bracket arm being free to be swung out of position to enable repairing of the welt and a rotatable guide wheel carried by said arm adapted to engage the upper of the shoe while the welt is being stitched thereto, said guide wheel having a narrow cylindrical face at the top portion thereof and a beveled peripheral face at the bottom portion thereof.
3. An attachment for a straight needle shoe stitching machine for stitching a welt to the up per and insole of a shoe after lasting, comprising a. bracket frame adapted to be fixed to the shoe,
stitching machine, a welt receiving channel in said frame, a bracket arm pivotally-mounted on the underside of said frame, and a guide wheel rotatably carried by said arm, said guide wheel having a cylindrical top portion and a beveled peripheral bottom portion adapted to engage the shank portion of the shoe while the welt is being stitched thereto, said bracket arm being adjustably mounted on the bracket frame, whereby the guide wheel carried by said arm is adjustable in position with respect to the welt channel.
4. An attachment in a straight needle shoe stitching machine for stitching a welt to the upper and insole of a shoe after lasting, comprising a bracket frame having an upwardly directed portion adapted to be fixed to a shoe stitching machine, means for guiding the welt through said frame, a guide roller adapted to engage the shoe as the welt is being stitched thereto, a bracket arm on which said guide roller is rotatably mounted, pivotal means for adjustably securing said bracket arm to the underside of said frame whereby said arm and the roller carried thereby may be adjusted laterally with respect to the welt or may be pivotally swung to move the roller out of contact with the shoe to enable repairing of the welt, and a stop pin for limiting pivotal movement of said arm in one direction so as to fix the position of the arm when the roller is brought to operative position for contacting the shoe.
