Application filed March 19, 1906. Serial No. 306,739.
To all whom it may concern:
- Be it known that 1, JOHN T. MoIsAAc, a citizen of the United States; residing at East Weymouth, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Shoe-Sewing Machines; and I do hereby declare the followin be a full, clear, and exact descri tion of M16 invention, such as will enab fe Others skilled in the art to which it appertains to make and use the same.
' In-the manufacture of welted boots and shoes it is-customary to beat out the welt after the welt has been secured to the upper and insole in order to cause it to lieflat in substantially the plane'of the insole. To
upon the welt after attachment to the shoe] and just prior to or at the time .ofv the beating-out operation. To she the welt strip before it is placed in the Welt sewing machine necessitates either a separate operation upon the welt vstri mechanism to the machlne for grooving and beveling the welt, which renders this machine more complicated in construction and slower in operation. Furthermore, when the slitting operation is performed upon the welt strip the slits are often made'of sufficient depth to appear upon the edge of the weltin the finished shoe and detract fromits appearance. Also, when theslitted welt strip is sewed to the shoe the inner edge of the welt becomes more or less stretched, so that the advantages intended to be'secured by slitting the strip are partially or wholly lost. When the slitting operation is performed upon the welt after the'shoe leaves the welt sewing machine, a separate operation must be performedupon tne welt either by hand or by a machine, or the welt beatin machine must be'complicated by the additlon thereto of a suitable welt slitting-inechanis [At this time the welt has hardened consi ably, and
when the slitting operation is performed by& machine more or less difficulty is experienced in' bending the welt into a position to" or the addition of- .beoperated upon by the welt slitting mechamsm.
The object of the present invention is to provide means whereby they slitting o eration may be performed upon the welt at t e same time that the welt is sewn to the shoe, so that a separate manipulation of the welt strip or of the shoe is rendered unnecessary, or the,
provision in the welt strip making machine or 1n the welt beating-out machine, of mechanism for slitting the welt.
With this object in view the present inven-, tion contemplates the provision in a welt sewing machme of a cutting mechanism acting automatically as the shoe is sewn to form a series oftransverse cuts in the under surface of the welt.
Broadly considered, the present invention contemplates the provision of a cutting mechism arranged in any suitable manner to permit the sewing operation and the welt slitting operation to be performed during one manipulation of the shoei It is preferred, however, to arrange the cutting mechanism to act in advance of the needle, that is, on the side of the needle away from the shoe, so that the cuts are made in the welt before it is at-' tached to the shoe. This arrangement of the cutting mechanism permits the use-of a simple construction winch does not add materially to the complexity of the mechanism of the machine and permits the shoe to be manipulated in preclsely the same manner as in an ordinary Welt sewing machine. This arran ement of the cutting mechanism also faci itatesthe sewing operation, as the welt is. made flexible by the transverse cuts and can be more readily applied to the shoe.
The invention contemplates the provision of any suitable form of cutting mechanism. In the preferred form of the invention, however, the cutter is mounted to'move towards and frqm'the welt so as to form a complete cut at each actuation thereof. The cutter is preferably arranged to. cooperate with the Welt guide, and to act on the welt adjacent that edge of the welt guide-which is next to the needle. This arrangement of the cutter causes the welt to be forcibly moved a slight distance. through the welt guide at each actuation of the cutter, so that the feeding of the welt through the welt guide is facilitated and endwise stretching of the welt is avoided, the welt being secured to the shoe in such a manner that a comparatively few blows of the welt beating hammer of the beating-out machine are required to cause the welt to lie flat in the plane of the insole. This action of I the welt slitting knife is considered of value,
-- following description.
and a feature of the invention is considered to consist, in the provision in a welt shoe sewing machine of a cutter arranged in any desired'manner to form a seriesof transverse cuts in the under surface of the welt as the shoe is sewn, and to force the welt through the welt guide to wards the shoe.
In the simplest and most efficient form of the invention which has yet been devised, the
cutter is mounted to move with the needle and to act on the welt while the needle is in the work, and to this end the .cutter is secured to the cap by which the needle is secured to its actuating segment.
In addition to the features of invention above referred to, the present invention also consists in certain devices, combination -.a and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art, from the The preferred form of the present invention is illustrated in the accompanying drawin s,inwhich x T igure 1 is a viewinside elevation of so. much of a curved hooked needle shoesewing machine as is necessary to show the connection of the present invention therewith; Fig. 2 isa detail. view inside elevationof the needl'e segment and the parts mounted thereon; Fig. 3 is a detail perspective viewillustrating the'manner in which the welt slitting cutter is elevation of a portion of the welt;
Referrin to the drawings, 1 indicates the curved hoo (ed needle, 2 the needle se ment,
. 3 the welt guide, and 4 the back gage o a welt tion.
2 in'the customary manner by means of a cap e 5 and clamping screw 6.
the knifecan be a justed to cut slits of the shoe sewing machine of well-known construc- The needle 1 is secured to the se ment The cap 5 is, however, of somewhat different shape from the capordinarily used, being rovided with a rearward extension 7 inwhic is formed a slot to receive the upper ortion or shank of a welt slittin knife 8. he shank of the knife is provide with a slot 9 through which a clamping screw 10 asses, by means of which desired de thin the welt, and be firmly secured in arfiusted position. Since the knife .8 is rigidly Secured to the needle cap 5, it moves towards from the welt with. the needle and acts upon the welt after the needle has penetrated the work. The knife acts upon the welt at the side of the welt guide next to the needle, and in order to permit. the knife to engage the welt at this point the upper plate of the welt guide is provided with a notch 11 as indicated in Fig. 5. During the cutting stroke of the knife the welt is su ported by the lower plate of the welt gui e, which plate, as best indicated in Fig. 1, is arranged at an an le to the direction of movement of the slitting knife. a slit in the welt which is inclined to the surface of the welt as indicated in Fig. 7, this being the form of slit usually formed in a welt The knife 6 forms a whenever the welt is slitted to facilitate the beating out operation' The advantages of this form of slit are well understood by those skilled in the art, and will be obvious without further description. As the knife en ages the knife is formed on the surface of the knife away from the needle, as is clearly shown in Fi sx3 and 5. r
in the operation of the machine the stitch forming devices and the other moving-parts operate in the usual manner, the operation of the machine being 'recisely the same as that of well-known 5 0e sewing machines with the exce tion that at each forward movement of t e needle a slit of substantially the form illustrated in Figs. 6 and 7 is cutting mechanism acting automatically as the shoe is sewn to form a series of transverse cuts in the under surface of the welt.
