- BROGKTON, MASSACHUSETTS cHANivnmne MACHINE Application filed December 4,1930. SerialNo. 500,110.

The invention has relation to channeling machines, such as that shown in the patent to Meyer No. 984,773, dated February 21, 1911.

In making shoes for wearers having flat feet it is common to provide an insole having a wing shaped shank portion thewing or Wings of which are turned against the sides of the last when the shoe is assembled, and after lasting, are held in such upturned position where they act as an arch support for I the foot of the wearer. To show this, reference is made to the patent to Orr, No. 1,482,- 140, dated January 29, 1924.

In this patent to Orr, the shank portion of the insole including the arch support wings is wider than the forepart and a special edge gage is necessarily used, and it is an object of the present invention to avoid the necessity for using a special edge gage for the purpose of channeling arch support insoles.

Also, it is necessary to bevel out these arch support wings by hand or to use a separate machine for the purpose, and it is another object of the invention to adapt the'machine of the said Meyer patent to bevel cut the arch support wings of the insoles. Other objects and advantages will hereinafter appear.

The invention consists in the novel construction and combinations of parts as set forth in the appended claims.

In the accompanying drawings illustrating an embodiment of the invention:

Figure 1 is a plan view of the invention as applied, partly in section.

Figure 2 is aside view of the same partly broken away. I

Figure 3 is a detail side view, partly in section, showing the outside knife in operation. Figure 4 is a similar view of a modification. Figure 5 is a detail planviewof the insole. Figure 6 is a fragmentary side view of the edge slitting knife in operation upon the insole.

Figure 7 is a plan view of the same. In these drawings, the numeral 1 designates the channeling or inside knife, of the usual character, and which cuts and turns up the flap 2. The knife is mounted in a groove in a knife block 3, being held therein in the customary manner and provided with the usual adjustment means.

The edge slitting or outside knife 4 has a rectangular shank fitting in a groove in a knife block 5, being fixed therein also in the customary manner and provided with the usual adjustment means. A presser foot 6 serves to limit the depth to which the knives enter the work and is mounted upon the knife carrier. The adjustment means provides for horizontal adjustment to vary the distance between the presser foot and the knives. The connection of the presser foot with its block permits vertical adjustment of the presser foot to'vary the depth of the cuts produced by the knives.

The work support or table 7 is mounted upon a stem 8 which is rotatably mounted in a vertical slide. The distance of the lip from theedge of the insole is determined by the edgegage 10 of the usual character as shown in said patent to Meyer, to which reference is made for the main constructional features of the machine. I

I In the present case, the table or work support 7 is provided with a dished upper surface, the central circular portion 11 of'which is flat, and the annular marginal p0rtion12 of which is inclined, the entire dished surface being similar to that of an ordinary saucer excepting that the inclined annular portion is straight in cross section. V

The insole 13 is provided with a single arch support wing 14, and the shank portion of the insole measured across said wing'is somewhat narrower than the forepart, whereby the ordinary edge gage may be employed, thereby avoiding necessity for a special edge gage as in the said patent to Orr.

The insole rests upon the work support or table and the edge gage acts as a stop to determine its position on the table as customary. The position of the edge gage is determined by the lever 106, under control of the opera tor. The work support being lowered and the insole placed thereon between the same and the presser foot, until it comes in contact with theedge, the work support is then allowed to rise and the operator guides the blank as it is fed through the machine. At

' the lip the junctures between the shank and the inside and the outside of the forepart of the insole the operator moves the hand lever 106 to vary the width of the margin as required.

The edge gage is controlled by the operator to provide the marginal arch support wing 14 of the insole, which is possible in this case due to the fact that the insole at the shank part across the arch support wing is narrower than the forepart.

The operator guides the insole so that at the time the arch support wing 14 is reached by the edge slitting or outer knife, the main or shank part of the insole will restupon the central fiat portion 11 of the Work table, whereas the arch support wing 14: will rest upon the beveled outer part of the table, thereby giving said arch support wing an upward incline.

In this way about one half of the Wing 14- will project above the top or outer edge of the table 7, and it is an object of the invention as previously explained to cut off this upper half of the arch support wing 14 or to bevel said wing, by an adaptation of the edge slitting knife f, in combination with the special form of table used herein. For this purpose the edge sliting knife 4: is provided with an outer extension knife 15, in line with the usual edge slitting portion 16' of said knife.

In order to temporarily maintain the outside lip 17 of the insole in vertical turned up position, a lip guard 17 is provided, being attached to the shank 20 of the edge slitting knife at 18.

In making of insoles by the Goodyear method, the arch support wing 14 is omitted, that is to say the operator guides the insole to omit the arch support wing, and in order to turn the outside lip 17 of the insole over and downwardly to horizontal position, the lip uard 19 is provided in substitution for guard 17 above referred to, being attached in the same manner to the shank 20 at 18.

The shank 20 is provided witha lower cutting edge 21, and a blade 22 extending laterally of the shank at both sides thereof and provided with the longitudinal cutting edges 15 and 16 aforesaid, and which are located at approximately right angles to the shank, see Figures 3 and 1. This shank 20 has its lower portion for a distance equal to the breadth of the blade 22 provided with opposite curved diversely beveled surfaces leading away from the shank cutting edge 21 and intersecting the upper surfaces of said blade at about right angles, to thereby gradually turn the outside lip of the insole, after said lip is cut or formed by knife edges 16 and 21, about forty-five degrees upwardly and at the same time resist any downward and inward or reverse movement of said lip.

I claim 1. In a channeling machine, provided with an edge slitting knife having a shank provided with a lower cutting edge and a blade extending laterally of the shank at both sides thereof and provided with a longitudinal cutting edge also at both sides of the shank, said shank having its lower portion for a distance about equal to the breadth of said blade provided with opposite curved diversely beveled surfaces leading away from the shank cutting edge and intersecting the upper surface of said blade at about right angles, to thereby gradually turn the outside lip of the insole to about forty-five degrees upwardly and at the same time resist any clownyvard and inward reverse movement of said 2. In a channeling machine, provided with an edge slitting knife having a shank provided with a lower cutting edge and a blade extending laterally of the shank atvboth sides thereof and provided with a longitudinal cutting edge also at both sides of the shank, said shank having its lower portion for a distance equal to the breadth of the said blade provided with opposite curved diversely beveled surfaces leading away from the shank cutting edge and intersecting the upper surface of said blade at about right angles, and a lateral downwardly extending lip guard attachment carried by said shank in rear of and spaced from said blade and engaging said outside lip to complete the turning thereof to vertical position. 7

3. In a channeling machine, provided with an edge slitting knife having a shank provided with a lower cutting edge and a blade extending laterally of the shank at both sides thereof and provided with a longitudinal cutting edge also at bothsides of the shank, said shank having its lower portion for a distance equal to the breadth of said blade provided with opposite curved div-ersely beveled surfaces leading away from the shank cutting edge and intersecting the upper surface of said blade at about right angles, and a lateral downwardly and latorally extending lip guard attachment carried by said shank in rear of and spaced from said blade and engaging the outside lip to complete the turning thereof to vertical position and turn it farther over and downwardly to horizontal posit-ion.
