To all whom 'it may concern:

Be it known that 1, AUGUST (loses, a citizen of the United States, residing at'Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented oertain Improvements in Machines for Operating'Upon the Edges of Soles of Boots and Shoes, of which the following description, in connection with the accompanying draw- 10 ings, is a specification, like reference characterson the drawings indicating like parts in the several figures.

In Goodyear or weltshoes ordinarily made, the outsole is attached to the Welt and, by means of the Welt,;to the upper portion of the shoe by stitches passing through the welt and outsole near their outer edges, the stitches lying upon theisurface of the welt. In certain cla-sses"of.work, however; it is '20 preferred that the stitches shall not be-visible .upon the Welt. For the purpose ofobtaining this result, various devices have been used to effect a depression of the line of I stitches below the surface of the Welt or otherWise to conceal the stitches. For example, the machine by which the outsole is attached to the" Welthas. been provided with a knife which forms a groove or channel in tli' up l ier surface of the ,Wel-t toreceive the 3dstltciesa A serious objection to this practhat'the effective thickness of the 'Weltis reduced and therefore a vital part of'tl'ie'shoe is weakened!" 4 A primary object of the present invention isto provide a inachiiie byjthe use of Which the line of stitches upon the upper side of the Welt may be concealed withoutwweakeuing' the Welt.- I f to v 'VV-ith the above object in View the-present 40 invention comprises means for upsetting the edge of the Weltori the upper por" on of; the projecting margin of the-sole; after ing of the outsole to the welt; smarts bring the upper portion of the projecting margin lose tothe ings,Figure 1 isa side elvatiQupartlwinr section, of a: machine; enibodyingatlieipmseuti invention; Fig. 2 is -a .plahn'of: ttrm medhlncei 100 "Drum Welt or the'we'lt and sole c" upper.

As shown in the drawings, 2 represents 5 the frame of the machine,.which may be secured to a bench, as indicated, or bolted to any suitable stand or support. A driving shaft 4, supported bybearings 5 of the frame, is provided with a fast pulley 6 and a loose pulley 8 of usual constructionl A portion 10 of the shaft 4 is reduced in diameter and is eccentric to the portion of the shaft within the bearings 5. Upon this eccentric '10 is" asplit or otherwise removable 1 block 12 which may slide in the lower slotted end .of a lever 14 pivoted at 16 in bosses 18 upon the bearin 5. To the upper end of lever 14, one on of a link 20 is adjustably connected by a pin and slot, the other end of the link being connected to. a slide 22 sup-' ported and guided in a uideway 24 formed in an upright. upon the ame 2. A plate 26 secured'to the upright retains the slide 22 in place. At the forward end of theslide is a removable pounding 'orupsetting tool 28. As illustrated in Flg. 3, the acting face of this tool comprises a lower slightly inclined portion 30 and anupper more sharply inclined ortion 32, between which is a shoul- 30 der or ead 34. Through the mechanism described, the slide 22 and the tool 28. will bevibrated in a direction at right angles to the, edge of the work for upsetting the edge, as hereinafter full-y explalned. 4

At-the side of the tool 28 is a tool 36 which may be similar in shape to tool 28 and which is carried by a lever 38, pivoted in the frame at 40 and operativel connected to the slidev 22, as, for example, a link 42 pivoted to Q the lever 38 at 44 and to the slide 22 at 46. Slide 22 may be slotted, as indicated in Fig.

2, to provide fora link of a difl erent length,

or otherwise 'to adjust the position of tool 36 with reference to tool 28. For supporting the work in proper rela -tion to the'tools, the machine is provided with a work sup ort mounted at the upper end of a spindle 52 having splines 54 which insure that the table will rotate with a rotatable sleeve=56 but which permit the spindle to move longitudinally through the sleeve. The lower end ofthe sleeve is pro-- vided with a flange 58 and a flanged ring 60', bolted to a bracket 62 mounted on the frame 2, securing the sleeve against longitudinal movement. The lower end 64 of spindle 52- is rounded to fi't'into a recess'in an enlarged, head 66 upon a rod 68 threaded at its lower against the end of the sleeve 72 while a' 77 is interposed between the washer sprm a-nd'flie head 66s0 that the washer limits threaded sleeve 72. A hand wheel 74 on the seam the upward movement of nut 70 and therefore of the table 50. The tension of spring 77 may be adjusted also through the nut. With the nut located as indicated in Fig. 1, the normal raised position of the table may be varied by adjusting the sleeve 72, in -or out but the table may ield downwardly to accommodate work of .varyin thickness, since it is supported b spring The table may be intermittently rotated by'the following mechanism: The sleeve 56 is provided with ratchet teeth, 80. Surrounding the sleeve is 'a cage or pawl carrier 82 rotatably supported upon the upper end of. ring and carrying two spring pressed pivoted pawls 84, 86 arranged to engage the ratchet teeth 80. H on bracket 62 are pivoted two s ring presse pivoted look ing pawls 88. 11 order to provide for a comparatively small feeding movement, the

pawls 84 and 86 are so arran ed that when I one of them engages the s oulder of a ratchet tooth the other will be half way be tween two teeth. Similarly one ofthe pawls 88 is'sli'ghtly' longer than the other so that they will engage the shoulder of each ratchet tooth alternately. A connecting link 90 is pivoted at its forward end to the cage 82 and at its rear end to a block- 92 adjustebly eonnected at, 94 to a flange 96 integralqvith the lever 14. a

To assist in the feeding of the work and also to serve as an edge gage, the machine is provided with a wheel having a flange 102. with a' slightly inclined milled or toothed soleengagingsurface. These teeth may be relatively long and sharp so that they will penetrate somewhat into the sole edge. At, the lower end of the wheel, ashank'1'04 fits into a hole 106 in the frameof the machine. The flange 102.and another flange 108 at the opposite end of the vwheel overlap the table 50 and the table is provided around its circumferenoe with gear teeth 110 meshin with teeth 112 upon wheel. 100 so that tab e and roll are compelled both to move verticallyand to rotate together.

'Work, which may be above described and themode f o erat-ion of the machine will be explained in ,connec-, tion with FigsB, 4, and5. As shown at 120, the. edge of the sole is done by the machinepreferably trimmed to a bevel and comparatively close to the upper and tot-he line of stitching by which the outsole is'secured to the welt before it is presented to.the .ma-v f chine illustrated. Ordinarily the machine will be used too'perate only uponthe fore distance only .from its edge. The edge 0f.

,fpart of .the sole and, if desired, a short disbeen upset, the engagement of the upper por{ tion of the sole with the rubbing tool '36 will prevent the lower portion of the sole from engaging the flange 102. With the parts in this position, the upper edge or tips of tools 28 and" 36"will be preferably at about the level ofthe upper side of the projecting.

margin of the sole orvery slightly above that surface and the edge or corner of head 34 will be preferably as low as the junction 'of weltand out-sole. As the pounding tool 28 is moved forward by the rotation of shaft 4 and eccentric 10, the acting face 30, 32, 3-1- ivill deliver a blow upon the upper portion ofthe edge of the sole and will upset it 'andbend it back toward'the upper. While the tool 28 is moving forward, the table 50 willbe stationary and the tool 36 will oscillate'about its pivot 40 away from the path of tool 28. As the (00128 makes its return stroke,the table will be rotated by the feeding mechanism described and, during the feeding movement of the Work, the tool 36 will move substantially in the line of feed but in the direction opposite to the move mentof the work and will act to complete the upsetting of the portion of the work previously acted upon by the pounding tool and will smooth down the upset edge so that it will have a shape somewhat as indicated In Fig. 3 and at 122 in Fig. 5. This tool 36 may also act to some extent to perform a rubbing function as it moves in the direction of feed upon the operative stroke of the up setting tool 28.

After the desired portion of the edge'of the sole has been submitted to the action of the tools 28 and 36 the edge may be set im- 'mediately or it may' be given'a final trimming and then set as indicated at'124, Fig. 5. If desired, also, the edge may be protate stitches. V

. While upsetting and rubbing tools of Va rious shapes may be employed, the form of tool shown in the drawings is believed to be preferable especially for the pounding op eration. The head 34 has an important function in crowding the portion of the sole to be upset toward the upper, since it sinks.
