STORM-WELT-STITCHING PLATE.
Application filed April 2, 1926. serial no. 99,316.
This invention relates broadly to a shoe sole stitching machine, and has more specific reference to an attachment which is to be used upon a conventional stitch machine of the well known Puritan Fair type. I
More specifically, the invention has reference to an attachment which is in the form of an improved plate construction for facil tating in the attachment of'a storm welt to a double ply shoe sole, frequently referred to in the trade-as a nailed shoe sole.
At the present time it appears to be a substantially universal practice to first stitch the two plies of the shoe sole together and to then staple the storm welt onto-the marginal portion of the upper ply. This requires the use of anattachment on a, staple fastening machine and involves two separate operations, making the presence gf an extra operator necessary to staple the storm welt onto the sole. In addition it involves additional costs of the wire staples and thework when finished is notaltogether satisfactory due to the fact that the staples are frequently improperly driven, allowing the materialof the welt to buckle between and to prov de water entrance spaces. it follows that while a storm proof shoe is advertised, it is not nearly as storm proof as could be.
What we propose to do is to provide a novel attachment for a conventional stitch machine, the same bein capable of being applied to the machine without requiring any alterations of the same, and being such as to permit the welt and both plies of the sole to be stitched together simultaneously. Thus,
in a single operation all three parts are stitched together in an efiicient manner, thereby rendering the cost of production considerably less expensive and providing a much better product for nailing onto the up er of the shoe.
'5 he structural features and advantages of the invention, together with additional objects will become apparent from the following description and drawings.
lln the accompanying drawings forming a part of this application and in which like numerals are employed to designate like parts throughout the same:
Figure 1 is a fragmentary view of a portion of a conventional sole stitching machine upon the plane of the line 77 of Figure 4:. 5
Figure 8 is a fragmentary View of a portion of the shoe sole with'the welt attached.
Figure 9 is a section taken on the line 99 of Figure 8.
Referring to the drawings and more particularly to Figure 1 it will be seen that the reference character 1 designates generally a portion of a head of a conventional shoe sole stitching machine which is shown resting upon a supporting plate or table 2. No detailed description of this part need be given. Rising from the horizontal portion 3 of the head is a standard a which terminates at its top in a shelf 5 which as is usual, is provided with a dovetailed, groove (not shown) in its top. Ordinarily, a removable plain stitching plate is fitted into this groove. in the present instance, however, the improved attachment is substituted. This comprises a plate which is generally indicated by the reference character 6, this plate being of general rectangular outline in top plan and being provided at one end with a dovetailed shaped rib 7 (see Figure 5) which rib is slidably received in the correspondingly shaped groove in the part 5 (see Figure 2).
Then as shown in Figure 4, this plate is provided in the left hand overhanging end portion with an elongated slot 8 to accommodate the needle. Also, it is formed with a transverse groove 9 which as shown in Figure 6 tapers from the forward toward the rear edge of the plate. On one side, the groove is formed with a countergroove 10 to accommodate the beaded portion 11 of the welt strip 12. This countergroove 10 en tends entirely across the plate. The groove 9 however terminates substantially at the forward end of the slot 8 and the portion beyond this slot is beveled and shaped as indicated at 13 in Figure 4, to accommodate the flexible edge portion of the Welt strip. A recess 14 is also formed in the top of the plate 6 and this intersects the groove 9, and is adaptcdto receive a removable member 15. Thus. as shown in Figure 2 when the strip 15 is in place and extends crosswise of the groove 9,-it provides an entrance opening for the welt of the shape shown in Figure 2. In practice, the welt is wound upon a spool 16 which is supported by appropriate brackets 17, and the free end portion of the welt passes through a tubular guide 18.
This guide as shown in Figure 1 is provided with a short arm 19 which is fashioned to provide. an attaching bracket. includes spaced fur-cations which straddle a retaining screw, bolt, or the like 20. This guide tube 18 is of the desired curvature, and is located with respect to the spool 16 to permit the welt strip to freely unwind and to travel -readily through the tube. The opposite end of the tube is also located to feed the welt properly through the groove 9. At this time we would direct attentionto the fact that a slide 21 is adjustably mounted on top of the plate 6 and this is provided with an upwardly directed end portion 22 against which the sole is firmly pressed during the sewing operation.
The sole, as shown in Figure 9 comprises a lower heavy ply of material 23 and a top ply 24. In this figure we have indicated the manner in which the welt 12 appears after it is stitched in place. A top plan view of the finished product is shown in Figure 8.
It is obvious from the foregoing that with the attaching plate 6 in position and the stop 22 properly adjusted with respect to the needle opening 8, the two plies of the sole are placed firmly down upon the plate in an inverted position. The customary feeder (not shown) serves to slowly feed the welt strip 12 so that by properly guiding the three elements beneath the needle they may be simultaneously stitched together. No doubt, this operation will be perfectly clear to those skilled in the art to which the invention relates. It is also believed that the construction and method of attachment of the invention will be clear, therefore, a more detailed description of the invention is thought unnecessary.
From the foregoing description and drawings it is obvious that the gist of the invention is in the provision of an attachment capable of being applied to a conventional marketed well known sole stitching machine without requiring alterations of the latter,
This bracket Y the attachment being'such in construction that it permits the two sections of a sole and a storm welt to be firmly stitched together simultaneously.
\(Vhile the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
Having thus described the invention, what we claim as new and desire to secure by Letters Patent is As a new product of manufacture, a storm welt stitching plate in the form of a substitute attachment for use on a conventional type of shoe sole stitching machine, wherein said machine embodies, among other parts, a vertical standard having a horizontal plate-like head at its top equipped with a dove-tailed groove for reception of a correspondingly shaped retaining tongue on an ordinary needle plate; said attachment comprising a substantially flat plate of general rectangular configuration, said plate being formed at one end portion and on its underside with a dove-tail retaining tongue for reception in the aforesaid dove-tailed groove, said tongue extending from the center of the plate to one end, said plate being provided in the remaining end portion with a transversely disposed elongated needle slot whose ends terminate in spaced relation from the longitudinal edges of the plate, being further formed in its top with a welt groove communicating with said slot and adapted to accommodate an ordinary welt strip, said welt groove extending transversely across the plate and through the opposite longitudinal edges of said plate, the groove being'gradually increased in depth toward the intake end having a countergroove for a bead on the welt disposed in spaced parallelism to said slot and being decreased in width and characterized by a short bevel at the discharge end, said bevel extending from an adjacent edge of said" slot through an adjacent longitudinal edge of said plate, said plate being also provided adjacent the intake end of said groove with a longitudinally disposed recess intersecting the groove, a welt confining strip fastened in said recess and bridging the intake end of the groove and disposed fiush with the top of the plate, and a slide mounted on said plate and having an upstanding guide disposed for cooperation with the edge of the shoe sole.
In testimony whereof we afiix our signatures.
