Application filed February 8, 1913. Serial No. 747,042.

To all whom it may concern:

Be it known that I, GEORGE J. KILB, a citizen of the United States,.residing at Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Machines for Operating on Insoles; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it same.

The present invention relates to machines for operating on insoles which are used in the manufacture of boots and shoes, and more particularly to machines for applying reinforcing fabric to insoles.

At the present time there are three types of machines for applying reinforcing fabric to insoles, namely; (1) machines for forming a bead or crimp in thereinforce and securing. it to the insole, commercially known as gennning machines; (2) machines for preliminarily tucking the material into the inside angle at the base of the lip, prior to the gemming operation, known commercially as forming-in machines, and (3) machines for tightening the reinforcing material about the lip of the insole, subsequent to the gemming operation, known commercially as ribtightening machines.

The object of the present invention is to appertains to make and use the improve the construction and operation of machines for applying reinforcing fabric to insoles, adapted particularly to perform the llb tightening operatlon, although, as

will be reco nized b those skilled 1n the art from the following description, certain I features of the invention are not limited to use in a machine for performing a rib tightening operation but may advantageously be employed in other types of machines for applying reinforcing fabric to insoles.

: Also certain other features of the invention may advantageously be employed in machines for operating on lipped insoles other than machines for applying reinforcing fabric thereto.

To theaccomplishment of this object-and such others as may hereinafter appear, the

features of the invention relate to certain devices, combinations and arrangements of parts, herelnafter described and then set forth broadly and in detail in the appended claims, which possess advantages readily apparent to those skilled in the art.

The various features of the present in-' vention will be best understood from an in spection of the accompanying drawings illustrating the preferred embodiment of the invention, inwhich: I

Figure l is a right side elevation of the machine; I

Fig. 2 is a detail in right side elevation showing the position of the parts during the operation of the machine and after the lip of the insole has been turned inward;

Fig. 3 is a detail in right side elevation of the devices for adjustably carrying the ironing tool; i

Fig. 4 is a front elevation; r

Fig. 5 is a sectional plan on the line 55, Fig. 4; V

Fig. 6 is a sectional elevation on the line 66, Fig. 4; l v

Fig. 7 is a detail in plan showing the-reinforcing fabrio trimmed on the feather, at the shank, along a line located within the edge of the insole; r

Fig. 8 is a detail in right side elevation showing the lip being ironed into its final angular form; and Fig. 9 is a transverse section through the working portion of the ironing tool on the line 99 of Fig. 8.

In the embodiment of the invention illus-v trated in the drawings the work support, upon which the unribbed or grain side of the insole rests While it is being operated upon, consists of a roll 1 mounted upon the forward end of a horizontal shaft 2 journaled in stationary bearings 3 formed in standards l and 5 projecting upward from a plate 6 carried by bench legs '7. The work support is positively driven during the operation of the machine through a gear 8 carried by the shaft, 2 and engaged by a pinion 9 carried by a stub-shaft 10. The shaft 10, carrying the fast and loose pulleys 11 and 12, is driven from a suitable source of powerthrough a belt drive. The belt is shifted from one pulley to the other, by hand, in the usual manner. In order to permit the position of the pulleys to be varied to meetv different conditions in diflerent factories the shaft 10 is ournaled in the lower end of an arm 15 projecting from a hub 16 rotatably mounted on a hollow bearing 16 projecting from the standard 5 about the shaft 2 and secured thereto by a set screw 17. By loosening the set screw the position of the pulleys may be changed by swinging them about the shaft 2.

The devices for operating on the insole supported on the work support to tighten the previously applied reinforcing fabric into the angles at the base of the lip consist of an inside tightening tool comprising a disk 18 arranged to press the reinforce into lip, and a reduced stem 22 which permits the bending of the upper portion of the lip inwardly in the manner hereinafter described. The reduced stem is formed on the lower end of a block 23 which is secured to the lower end of a hollow spindle 2% by means of an elongated rod (not shown), carried by the block 23, and a nut 25 threaded upon the upper end of the rod and arranged to engage the upper end of the spindle 2a. The spindle 24: is provided at its opposite ends with frusto-conical shoulders 26, each of which rotates, during the passage of the insole through the machine, on a ball bearing 27 carried in a race 28 formed in each end of a thimble 29 carried by a tubular sleeve 30. The thimble 29 is forced downwardly so as to press the disk 18 firmly against the face of the insole by a spring 31 coiled around the thimble and interposed between a peripheral shoulder 32 formed on the thimble and a knurled cap 33 threaded for adjustment upon the exterior of the sleeve 30. In order to limit the downward movement of the disk 18 under the influence of the spring 31, thesleeve is provided with a circular seat 3 1 for the shoulder 32 on the thimble. In order to permit the position of the disk 18 to be varied as desiredv the sleeve 30 is loosely carried by a cylindrical block 35 in a casing 36. The block 35 is provided witha stem 37 rotatably mounted in a split clamp 38. The clamp 38 is slidably mounted on a horizontal rod 39 projecting from an arm 10 adjustably setion of the block 35 in the clamp 38 and sliding the clamp 38 along the rod 39. The inside tightening tool 18 may also be advanced or retracted in the line of feed relatively to the outside tool by a combination of some of these adjustments. In order to provide a single means for holding the sleeve 30 in adjusted position in the block-35, for holding the block 35 in its casing 36 in adjusted position on the clamp 38, and for holding the clamp 38 in adjusted position on the rod 39, the stem 37 on the block 35 is threaded to support a butterfly nut 41-. Rotation of this butterfly nut frees or clamps the parts hereinbefore referred to at the Will of the operative.

The wheel '19 is secured on the lower end of a stub-shaft 15 which is rotatably mounted in a bearing 16 formed on the frame -12. The wheel 19 is positively driven during the operation of the machine from a counter shaft 41-7, journaled in the frame d2, through bevel gears 48 and 49 carried respectively by the shafts a5 and 17. The counter shaft 17 is driven from the main shaft 2 through a train of gears 50. The wheel 19 is provided with a frusto-conical portion, the face 51 of which is arranged to engage the reinforcing fabric on the feather of theinsole and cooperate with the work supporting roll 1 in feeding the insole through the machine. This portion of the wheel 19 is arranged with the peripheral edge 52 of its larger base in engagement with the outside angle at the base of the lip. As the face 51 is provided with teeth, to aid in the feeding of the insole, the edge of the face in contact with the outside angle at the base of the lip is serrated. This saw like edge acts to firmly press the reinforcing fabric down into the angle at the base of the lip, consolidates the material at the base of the lip, and produces a sharp corner where the lip begins to rise from the face of the insole.

The face 51 of the wheel 19 is also arranged So that, when in working position, itsfl feather engaging surface inclines to ward the edge of the insole. The work supporting roll 1 is preferably beveled as at 53 so that its feather supporting surface is substantially parallel to the feather engaging surface 51 of the wheel 19. With these parts thus constructed and arranged they will act to mold the feather down at an 'angle to the body of the insole and impart a dish to the unribbed face of the insole in the manner shown in Fig. 2. It is important that theinsole be dished in the manner described at the time the rib is tightened for the reason that if the insole is left lat on its unribbed face the transverse bending neces sarily imparted to the insole when assembling it on the last will Loosen the fabric at the base of the lip and the good effect of the rib tightening operation will thus be nulliport 46 and the bottom of the lever.

fied. The dishing of the insole providesfor fitting the bottom of the last without undue strain'on the fabric. The roll 1 may also be provided with a comparatively greater beveled portion 54. By arranging the work support with this bevel 54 beneath the feather of the insole, and associating therewith a wheel 19 having a feather engaging face parallel to the bevel 54, a greater dish, as is desirable in some styles ofshoes, may beimparted to the insole. f

I have discovered that if the base'aridupper portion of the lip stand substantially perpendicular and parallel respectively to the face of the insole that when the sole is bent transversely to the curved bottom of the last in the assembling operation, the lip will then stand at the proper angle to the bottom of the last for the convenient and proper lastin and sewing of the shoe. That is, asubstantially right-angular bend at the upper portion of the lip will provide an excellent abutment for the channel guide of the welter and will so stiffen the lip that it will not be knocked out of shape in the lasting operation. In order to bend and set the upper portion of the lip inwardly substantially'parallel to the face of the insole, the wheel 19 is provided with a vertical face 55 arranged to engage the lower portion of the outer side of the lip and with a face 56 arranged substantially perpendicular to the face 55 to engage the upper portion of the outer side of the lip. with this construction the base and upper portion of the reinforced lip are acted on in such manner as to cause such portions to stand substantially perpendicular and parallel respectively to the face ofthe insole. By mounting the disk 18 on a a reduced stem a support is provided for the inside surface of the lip which cotiperates with the faces 55 and '56 in shaping the lip into. the desired form.

After the upper portion ofthe lip is bent inwardly it is desirable to iron the bent lip after it is removed from the influence of the tools 18 and 19 in order to set it in its final form with sharp,-unbroken edges, and insure that it will remain permanently bent inward. To this end an ironing tool, comprising a bar 57, projects over the lip across the line of feed (Fig. 8) This tool projects from an arm 58 which has a houlder 59 (Fig. 4). The shoulder 59 is bolted to one end of a lever 60 centrally pivoted on the bearing 46 (Fig. 3). The lever 60 is nor mally actuated in one direction by a spring 61, interposed between the top of the s pphe tension of the spring and the position of the lever are controlled by suitable adjusting and locking screws 62. The tool 57 isnormally adjusted so that it extends beneath the face 56 of the wheel 19, atthe rear of the tool 18, in the manner shown in Figs.'8

and 4. -;As shownin Figs4and 9 the work engaging face of the tool 57 is beveled, with its beveled edge directed toward the formmg tools, so that the rib may, easny pass beneathit and the upper portion of the rib may be additionally bent after the rib passes from the infiuenceof the face 56 on the wheel 19. The purpose of bringing the lip to substantially the form shown in Fig. 8 is to provide a well defined lower portion to receive .the thread in the .inseaming operation, and by the sharp corners and edges the points of operation ofthe tools be trans ferred around the various curvatures of the insole without attention on the part of the operative except to insertv the insole into the machine and remove it therefrom at the completion of the operation. In the present machine this result is accomplished by oppositely engaging the rib of the insole in advance of the point of operation of the insole feeding face 51 of the wheel 19. The rib is engaged on its inside by the inside tightening tool 18. On its outside the rib is engaged by a guide 63 which is mounted for vertical adjustment on the bearing 46. The guide. 63 is curved to extend beneath the face 56 in proximity to the wheel 19so that its operating portion may extend over the feather and engage the rib at the proper point a v f It is desirable, from a selling point of view, that a portion ofthe reinforcing fabric be removed fromabove the outer margin of the feather at the shank portion at least. The preferred manner. ofaccomplishing this is by trimming the fabric at the shank along a line located within the egde of the insole. In the illustrated em. bodiment of the invention a trimming'knife 64 is formed on the end .of a cylindrical shank 65 arranged substantially parallel to the surface of theinsole. The shank is secured by a set screw 66 to a split block 67 arrangedto be clamped by means of a butterfiy nut 68 to the horizontal arm 0f a bent rod 69, the vertical arm of which is secured to a bracket70 projecting from the standard 4, by means of a bolt 71. With this construction the knife may be adjusted longitudinally by shifting the shank 65 in theblock 67, laterally by shifting the block 67 on the horizontal arm of the rod 69, and vertically .by shifting therod 69 in the bracket 70. As heretofore pointed out, it is desirable, particularly at the shank of the insole, totrim off or otherwise position the edge of the reinforcing fabric within the edge of the insole. In the illustrated embodiment of the invention, in operating.

upon a particular size of insole the knife 6a is adjusted preferably, although not necessarily, so that it just clears the edge of the insole around. the forepart. As the width of the feather is greater at the shank than it is around the forepart of the insole, it is evident that with this arrangement of the knife the reinforcing fabric will be trimmed along a line on the feather, at the shank, within the edge of the insole as its point of operation is transferred along the shank of the insole; The result obtained is illustrated by Fig. 7..

The rib tightening tools are held down upon the work by means of a spring 72, one end of which is connected to a hook 73 on the plate 6 and the other end of which is connected to a pin 74 carried by the frame 42. The pin 7% may be vertically adjusted in the frame 42 to vary the tension of the spring 72 by a butterfly nut 75. In order to elevate the frame 42 to permit the ready removal and insertion of the insole the standard t carries a centrally pivoted lever 7 6, one end of which is connected to the frame 42 by a link 77 and the other end of which is connected to a treadle (not shown) by a treadle rod '7 8.

Preferably the rib tightening tools, as well as the lip ironing tool, are heated, as it has been found that the lip is better turned and acquires a more permanent shape if the operationsare performed with the tools at an elevated temperature. The heat of the tools also renders the reinforcing fabric correspondingly more plastic and pliable. The application of heat may be by'means of a gas flame such as is used for heating the tools of stitch wheeling and other machines for operating on shoe soles.

It will be understood that the specific construction and arrangement of the parts is not mate ial to the broader features of the invention and may be varied and modified without departing from the invention.
