JOINT-MACHINE AND WELT-CUTTER.

Specification of Letters Patent.

Patented Apr. 23, 1912.

Application filed December 14, 1907. Serial No. 406,424.

welt has been cut or the shoe jointed, much diificulty has been experienced in securing the required smoothness of the upper at the shank and the desired neatness of the joint. This is due to the fact that in the welting operation the running on and off of the stitching which occurs at the point of joint between the heel seat and shank tends to throw out the rib of the inner sole and leave the inner scam in a position which so far overlies the margin of the inner sole that when the outer sole is stitched to the welt the table will strike the inner seam and thus guide the stitch away from its true line along the shank. When the shoe is trimmed therefore there is a liabilitythat the trimmer will run into the stitching which will expose the same and ruin the shoe. In order to overcome this difficulty and secure the desired result without the delay'caused by the slowness of hand work and clumsiness of the result, I have devised my present invention which automatically engages with the welt and upper at the required point and draws them smoothly over the last, presses back the inner seam to its normal position, and securely holds them while the operative fastens them in place.

This invention I have more fully disclosed in the accompanying specification in which I have described a machine which embodies my invention and in addition to this description I have set forth in the drawings forming a part of the specification views of such an embodiment to illustrate the principle of my invention.

Throughout the specification and drawings like reference numerals indicate corre-.

sponding parts and in the drawings Figure 1 is a side view-of my machine, Fig. 2, an end view partly in section, Fig. 3, a plan view, Fig. 4, a perspective view showing a shoe positioned and under operation, Fig. 5,

a section of the welted and lasted upper at the shank, and Figs. 6 and 7 views of the cutting knife.

1 is a bed in which is formed a longitudinal slideway 2. 3 is a slide movable along said slideway and bearing a support 4 which through the coiled spring 5 affords a yielding support for a last 6 on a block 7 which is hinged on said slide 3. 8 is an adjustable toe support also mounted on the slide 3.

9 is a pair of oppositely disposed boxes in which are formed transverse slideways.

11 is a pair of oppositely disposed transverse slides which are normally retracted by the springs 10 in the slideways 10 and are simultaneously operated therein by means of bell-crank levers l2 pivoted in the boxes at 1-3 and having engagement at their upper ends with the slides 11 and at their lower ends connected by suitable rods to a treadle or other operating means (not shown). On the slides 11 are adjustably mounted pressure fingers 14 formed with crooked ends 14 which are adapted to slide over a last to draw the upper smoothly over it. The ends of these bent portions 14: are brought to a thin slightly rounded edge 14: which is adapted to catch the upper :20 and welt 21 at the seam 22, draw them smoothly over the last and at the same time press back the rib 23 to its normal position.

15 is a stop on the upper face of each finger 14: near its edge 14 on the side opposite to the shoe. As the welt end runs over this stop the operative may out against it with a skiving cut allowing the welt to be severed uniformly on the two sides of the shoe.

16 is a stop adjustable at 16 to afiord the proper location of shoes of different sizes and thuspermit the operative to out quickly slightly forward. When the heel strikes the stop 16 the slides 10 are thrown forward by the levers 12 which are operated by any suitable means such as by foot treadle or by a power shaft. As the slides 10 advances the fingers 14 engage the seam 22 of the upper 20 and the welt 21 at the shank and cooperating with the upward pressure of the springs 5 and"? draw the upper smoothly over the last pressing back the rib 23 which has been bent out by the Welting machine and hold these parts until retaining tacks can be driven. With the parts thus held the operative may then cut the welt ends of! evenly and accurately against the stops 15 by means of a cutting knife 17 shown in connection with Fig. 5. When the upper is finished the slides 10 are allowed to be returned by the springs and the slide 3 returned to its initial position in which the shoe. may be removed and another piece of work substituted.

Various modifications may obviously be made in the form and arrangement of the parts of the embodiment of my invention shown without departing from its spirit.
