Specification of Letters Patent.
Fatented Jan.. 23, 101% Application ilerl November 23, 1914.-. Serial No. 873,538.
To all whom t may concern.'
Be it known that l, FREDERIC E. Bnn- 'rit-inn, a citizen of the United States, residing at Lynn, in the county of Essex and State of `li/lassachusetts, have invented certain new and useful Improvements in Channeling-Machines; and l 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 appertains to make and use the same.
rlhe present invention relates to machines used in the manufacture of boots and shoes for forming a channel, or a feather, or both, in the marginal portion of the insole, such machines being known generally as channeling machines.
More particularly the invention relates to that type of channeling machine for operating upon welt insoles disclosed in Letters Patent of the United States granted to the present inventor, No. 1,023,801, dated April 23, 1912. ln this class of machines the insole is fed through the machine automatically, but it is swung about an edge gage by the operative to maintain the knives in proper relationship to the sole edge as thel point of operation of the knives is transferred around the insole.
.ln the manufacture of mens shoes, especially the higher grade, it is customary after the edge cut has been made to the insole to place the insole in a skiving machine and by a second operation skive od the feather at the shank to give the feather a thin edge. ln making the edge cut in a welt insole, the operative shifts the edge gage to vary the width of the feather at various portions of sole. When an extension outsole is desirable at the ball or toe of the shoe the feather in made narrow, while at the shank, where the outsole is trimmed in close, the feather is made wide. lt isthis wide feather at the shank that is desirable to skive off. With the feather wide and skived off thin the shank of the-insole is quite flexible and can easily be worked down over the convex surface of the shank of the last to give an even, close shank, and a nice appearing shoe. Further, with such an insole fitting, z'. e., close to the shank of the last, the needle of the welter is permitted to strike in close and place the inseam stitches at the base of the between ysubstance which was not possible in menls shoes of large size using a heavy insole having a square out feather. The two operations necessary to produce an insole with a beveled feather is, obviously, quite expensive.
TWith these considerations in view, the object of the present invention is to provide that when the edge gage is shifted to produce a wide feather at the shank, the edge knife will be tilted to produce a beveled cut and thus give the feather a thin edge.
ln carrying out this object of the invention the machine of the patent hereinbefore referred to may be utilized by providing a swinging edge knife for the usual rigid, Xed edge knife. The present novel edge knife is maintained in a rotatable jaw in such a manner that the cutting end of the knife is at the center of rotation of the jaw. The knife is connected with a slide in the knife block and this slide in turn is attached to the edge gage lever which, when operated sets the edge knife so as to make either a square or bevel cut. In the preferred form of the invention the edge knife is set for a bevel cut when the edge gage is moved in to make a wide feather at the shank but the invention, as defined in the claims, is not limited to this particular control.
These and other features of the invention, including certain details of construction and combinations of parts, will be further eX- plained in the following description and more particularly pointed out in the appended claims.
rlhe preferred form of the invention is shown in the accompanying drawings in which:
Figure 1 is a rear elevation of a welt insole channeling machine with the improved swinging edge knife incorporated therein; Fig. 2 is a left hand, side elevation of the machine; Fig. 3 is a sectional, plan View showing the edge gage and its connection with the improved edge knife; Figs. l and 5 are side elevations of the swinging edge knife block, with its cover plate removed,
showing the knife in position for square and bevel cuts respectively', the knife swinging slide being shown in dot and dash lines as it is in a plane in front of the parts shown in full lines. Fig. 6 is a vertical, sectional detail on the line 6-6 of Fig. 4 looking in the direction of the arrow; Fig. 7 is a section on the line 7-7 of Fig. 4, looking in the direction of the arrow; Fig. 8 is a perspective view showing the guideways in the edge knife block to receive the knife jaws; and Fig. 9 is a perspective view of the edge knife jaws with their curved guides.
The construction and mode of operation of the machine shown Ain the drawings, eX- cept for the additional features forming the subject matter of the present invention, are substantially identical with the construction and mode of operation of the machine disclosed in my prior patent. rhis type of machine for operating upon welt insoles is previded with channel and edge knives sustained in a knife carrier mounted for oscillation in the line of feed over a work support, presser and feed gages associated with the channel and edge knives, an edge gage movable both across and in the direction of feed, and a yieldingly mounted work retainer provided with a foot which has a serrated under surface for firmly engaging the face of the insole. The sole is fed on the forward movement of the knife carrier, being carried forward by the 'engagement of the presser gages, the knives at this time riding over the sole. When the limit of the forward stroke of the carrier is reached the work retaining foot is moved down into contact with the sole to hold it rigidly7 from movement. As the knife carrier moves backward the knives enter the sole, move toward the work retainer and produce the channel and edge slit in the sole.
ln the embodiment of the invention illustrated in the drawings, the channel knife 1 is adjustably mounted in a carrier 2 secured to a bracket 3 projecting from the lower end of a slide 4. The edge knife 6 is adjustably mounted onv the slide 12 and the two slides 4 and 12 are held within the oscillating carrier 18 by a cover plate 19. rlhe channel knife and edge knife slides are adjustable vertically by the thumb screws 8 and 9 respectively.
rlhe usual chamfer knife 5 is mounted below the work table 7 to bevel off the unchanneled face of the insole. Above the table the work retaining presser foot 24 (partly broken away in Fig. '2) is adj ustably mounted on the lower end of a rod 25 carried by bearings 26 on a vertically reciprocating slide 27. The rod 25 is provided with lock nuts 28 supporting a coiled, take up spring 29 which surrounds the rod and bears at lits upper end against the lower surface of the upper bearing 26. The upper end of the rod is provided with lock-nuts 30. lntegral with the slide 12 is an arm 13 to which is attached the edge knife presser foot 14.
Referring now particularly to Figs. 2 and 3, the machine is provided with the usual edge gage 20 mounted in a slide (Fig. 1) wl 'ch moves with `the knife carrier along the line of feed. The slide 23 with the edge gage thereon is mounted upon a second slide which has a recipro :ating movement at right angles to the movement of slide 23, e., across the line of feed. The slide is moved in and out over the work table by means of a handle 31 which is rigidly connected with a shaft 31. fr block o2 is fastened to the upper end of the shaft 31 and carries a rotatable slide that works in a guideway 35 in a li'er which is pivoted to the machine frame. rl"he end of the lever 32 carries a toothed segment which works in the rack 84 attached to the slide 22 so that any movement of the handle 31 will reciprocate the slide 22 by means of a lever 82. Mounted on the block 32 and above the lever 32 is a cam plate 36 with a cam surface 37 and 37 (see Fig. 3). A lever 38, provided for swinging the edge knife, is pivoted to the machine frame at 60 and carries a roll 39 at its outer end which is cn- 9 gaged by the cam surfaces 37 andl of When the roll is engaged by the surface 37 the lever 88 is not moved to swing the edge knife since this cam surface is a true are of the rotation of the cam plate 36. rFhus the lever 81 for operating the edge gage can be rotated through an arc corresponding to the length of the cam surface 37 and the position. of the edge knife will not be altered. The length of the cam 37 is such as to allow sufhcient edge gage movement to provide the varying width of feather required at all points from the toe to the ball line, but when a greater movement of the edge gage is had, to provide for the wide shank feather, the cam surface 37 is caused to act upon the roll 39 to actuate the lever 38 and to swing the edge knife to a position to make a beveled cut. Upon the inner end of the lever 38 is swiveled a channeled block Al1 (Figs. 1 and 2), that receives an arm 42 of a knife swinging slide 57 (see Fig. 2 and dot and dash lines Figs. 4 and This sliding connection between the knife slide 57 and the lever 38 permits the knife carrier 18 to oscillate freely while maintaining at all times an operative connection between the lever 38 and the swinging edge knife holder.
rlhe edge knife block 43 is adjustably mounted upon its slide 12 by a set screw 58 fitting in an elongated slot 45. The edge knife 6 is clamped between the jaws 52 (Fig. 6) of a rotatable knife holder 47, by a screw 54. The knife holder 47 has curved guides 55 (Fig. 9) which work in curved guide ways 46 provided in the knife block 43. At the side of these guides and integral with the knife block is a side plate 47 which has a slot 48 (Figs. 4 and 5). When the guides on the knife holder are placed in the guide ways 46 the side plate 47 bears upon and is movable over the outside face of the knife block 43. Integral with and raised above the face of the knife block 43 are lugs 44 to hold a cover plate 56 in which the knife slide 57 is mounted (see Fig. 2). rlhis knife slide 57 carries a lateral pin 49 which has swiveled thereon a block 5() that works in the slot 48 of said side plate 47. VWith this construction any movement given to the slide 57 through the lever' will swing the knife holder 47 in its guideways. rEhe edge knife is so placed in the jaws of its holder 47 that its cutting end is at the center of rotation of the holder. rl`his is highly important as such a. construction produces a bevel, at all angles, extending from the edge of the insole to the shoulder. Then the knife block is in position to make a square edge feather the plate 47 rests against the shoulder 51 on the knife block 43, as shown in Fig. 4, with the block 50 at the outer end of the slot 43. When the knife is rotated to cut on a bevel the movement of the slide 57 has brought the block 50 to the inner end of slot 48 as shown in Fig. 5. Thus the knife is held rigidly in either position.
ln the operation of the machine at the time a sole is started the handle 31 which controls the position of the edge gage 2O is in the dotted line position in Fig. 3, that is, the edge gage has been moved into its position for the production of a wide feather by the edge knife. Consequently, the roll 39 on the lever 33 is at the opposite end of the cam groove 37-37 from that illustrated in Fig. 3, and the edge knife swinging slide 57 is in the position shown in Fig. 5, thereby swinging the edge knife to its position for making a beveled feather edge. rlhe insole is fed through the machine, by the sole feedinstrumentalities described in my patent hereinbefore referred to, until substantially the ball of the insole is reached at which time the handle 3l,is moved forward in order to bring the edge gage forward and cause the edge knife to make a narrower feather at this point. A movement of the handle 3l in the direction named rotates the cam plate 36 and the cam groove 37 in a direction to swing the rear end of the lever forwardly and thus carry the knife swinging slide 57 forward. This slide travels in horizontal plane and, consequently, the pin 49, upon which the block 50 working in the slot 48 of the knife holder 47 is mounted, travels in a right line path. rllhe forward movement of the block 50 as it travels from the rear end to the forward end of the slot 48 imparts an upward movement to the knife holder 47 on its curved guide carrying the edge knife with it. The moving parts are so designed that at the completion of the forward travel of the block the edge knife is lever 33 to the portion 37 of the cam groove u which, as has been described, is a true arc of the rotation of the cam plate 36. rlherefore, further movement of the lever 3l 'within the limits of the cam groove 37, to vary the width of feather as the knives operate around the forepart of the insole, does not alter the position of the edge knife as shown in Fig. 4. l/Vhen, however, the opposite ball of the insole is reached and it is desired to again produce a wide feather along the shank, the handle 3l is again moved backward to its dotted line position (Fig. 3) which causes the cam 37 to actuate the lever 38 and move its rear end in a reverse direction to that heretofore described. moves the knife swinging slide 57 inward and carries the block 50 from the forward end of the slot 48 to its rear end, thus pulling the knife holder 47 downward and swinging the edge knife to an angular position in which it is caused to again produce a beveled feather cut.
`While it is preferred to employ the specific construction and arrangement of the parts shown and described, since this construction and arrangement is the simplest and most eflicient embodiment of the invention which has yet been devised it will be understood that this construction and arrangement is not essential except so far as it is specified in the claims, and may be varied or modified without departing from the broader features of the invention.
