SOLE-MACHINE.

Patented June 25, 1912.

To all whom it may concern:

Be it known that I, Fnnnnnrc E. BERTRAND, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain new and use-ful Improvements in Sole- Machines; 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 appertains to make and use the same.

This invention relates to sole machines and more particularly to machines for providing the insole with a marginal abutment or lip which is used in the inseam sewing.

operation to secure the upper and parts within it to the insole.

A great desideratum in making shoes is to provide the contour of the shoe at the welt crease with an outline of fair curves, that is, the contour of the shoe at this place should not be marred by protuberances or lumps caused by some of the parts beneath the upper not having been lasted or sewn down tightly and evenly to the last and insole. One cause for marring the appearance of the contour of the shoe at the welt crease has been the bulging, beyond the line forming the contour of the sole of the last, of the forward ends of the counter. This has been due to the fact that there has not been a sufficiently wide feather formed by the insole channeling machine at this point properly to take care of the extra stock supplied by the use of a counter at this point. It has been customary heretofore in channeling insoles to vary the width of feather, as the sole is fed through the channeling machine, by adjusting the edge gage across the line of feed and so far as is known to the inventor but three predetermined positions for the gage under control of the operative has been provided. With these three positions the feather at the toe, sides of the forepart, and shank may be made of varying widths. The width of feather used at the shank is run down past the breast of the heel to a point which will be covered by the forward ends of the counter. In lasting the shoe at the breast of the heel, with a feather of this width upon the insole, it has been found that there is not suflicient room to snugly seat the forward ends of the counter. Therefore, when the welt is attached, during the inseam sewing operation, the passage of t-he needle through the improperly lasted counter causes the forward edges of the counter to bulge and form an unsightly projection beneath the upper on t-hefinished shoe, mai-ring the appearance of the shoe at this point.

The object of the present invention is to overcome this and similar .difficulties and insure that the appearance of the shoe at the welt crease will be pleasing, no matter how many layers of material are used in the construction of the shoe upper In accordance with this object, the present invention contemplates the provision, in insole channeling machines, of an attachment permitting a feather of suilicient width to be formed at that portion of the insole adjacent the breast line of the heel to properly take care of the counter and other materials which it is necessary to last and sew at this point.

A feature of the invention, therefore, comprises means whereby the edge gage may be adjusted across the line of feed to any one of four predetermined positions relative to the lip forming means. This permits the operative to cause the lip forming cutter to cut a feather of sufficient depth at the beginning and end of the channeling operation to properly take care of the forward ends of the counter Vwhen they are thereafter lasted and sewn in the further operations upon the shoe. A series of stops are used to determine the positions of the gage and these stops are preferably made adjustable so that the desired positions of the gage may be variably determined in accordance with the style of the shoe into which the insole being operated upon is to be incorporated.

Other features of the invention relate to certain devices, combinations and arrangements of parts hereinafter described and claimed, which possess advantages in simplicity of construction and ease of manipulation which will be apparent to those skilled in the art.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a plan of the improved attachment for sole channeling machine shown connected to the edge gage of the machine illustrated and described in Letters Patent of the United States to )William C. Meyer, No. 984,773, dated February 21, 1911. Fig. 2 is a front elevation of the improved attachment; Fig. 3 is a central vertical section of the parts shown in Fig. 2; Fig. 4 is a detail showing an underside view on the line 4--4 of Fig. 3; and Fig. 5 shows a sole having sketched thereon in dotted lines a counter located as in the completed shoe.

In the embodiment of the invention illustrated in the drawings, 1 represents a bracket which sustains the work support 2 in the machine of the patent hereinbefore referred to, and 3 represents the edge knife of said patent which forms a lip and feather along the margin of a sole as shown in dotted-lines in Fig. 1. The distance of this lip from the edge of the sole is determined by an edge gage 4 and the width of the feather is varied by moving this gage across the line of feed. 'As shown in Fig. 1, the gage 4 is provided with a toothed shank 5 which is engaged by a segmental gear 6 xed to the upper end of a rock-shaft 7 which is journaled in a bracket 8 mounted upon the upper end of the slide which carries the work support 2. The bracket- 8 is provided with a horizontally arranged shank 9 slidable in and ,out in a guideway on a horizontal projection 10 also carried by the slide which sustains the work support 2. The shank 9 is adjustably secured in position by means of acollared set screw 11 passing through a slot in the shank 9 and threaded into the projection 10. The rockshaft 7 carries at its lower end a reciprocatory 4member 12, specifically a crank arm, which is provided wit-h a forked end engaging a block 13 swiveled upon a disk 14 fixed to t-he upper end of a second rock-shaft 15. The rock-shaft. 15 is supported by being journaled in a bracket 16 also carried upon the project-ion 10 of the work support slide. The rock-shaft 15 has a head 17 pinned on its lower end to which there is pivotally connected a hand 'lever 18 by means of which the rock-shaft 15 may be oscillated. )Wien the rock-shaft 15 is so oscillated, the swivel block 13 reciprocates the arm 12, thereby in turn Oscillating the rock-shaft 7 and segmental gear 6 thus moving the edge gage across the line of feed.

' As heretofore explained, it is desirable that means be provided for adjusting the edge gage to four predetermined positions. To accomplish this end the construct-ion and arrangement nowY to be described is preferably used. A pin 19 projects from the lower side of the disk 14 into a recess at the upper end of` the journal for the rock-shaft 15 and by engaging the forward end m (Fig. 1) of said recess limits the extreme forward position of the gage or the position which it occupies when channeling with the narrowest margin, that is, between the points c-cl and e-f (Fig. 5). The adjust able connection between the shank piece 9 and horizontal project-ion 10 permits a variation of the extreme forward posit-ion of the gage determined .by the stop just described and for this purpose an adjusting screw 20 is' provided which is threaded into the projection 10 and is provided with a flange 21 (dotted'lines Fig. 1) engaging a slo-t in the shank 9 whereby the shank may be moved in and out and the gage 4 adjusted across the line offeed when the set screw 11 is loosened;

The extreme rear position of the gage is determined by a pin 22 carried by a collar 23 clamped to the disk 14 which pin projects into the same recess which receives the pin 19. The pin 22, when the lrock-shaft 15 is moved in a counter-clockwise direction viewing Fig. 1, engages the rear wall n of the recess and thus limits the extreme rearward position of the gage. This position of the gage is used in cutting `the feather between the points a--J and gdb, Fig. 5. It will be observed that a variation in the extreme depth of the feather can be readily obtained by adjusting the clamping collar 23 upon the disk 14 so as to cause the pin 22 to engage the rear wall n of the recess sooner o-r later as-the rock-shaft 15 is oscillated.

One of the intermediate positions of the edge gage is determined by an engagement ofa latch 24 carried by the hand lever 18' with. a recess, or slot, 25 (see Fig. 4) in a flange 26 upon the lower end of a sleeve 127 surrounding the rock-shaft 15. The sleeve 127 is mounted for angular adjustment relative to t-he rock-shaft. By adjusting the sleeve the relation of the slot 25 to the pins 19 and 22 may be varied. The intermediate j position of the gage determined by an engagement of the latch 24 with the slot 25, in the present construction, provides for the width of feather between the points cZ-e of Fig. 5. The other intermediate position of the edge gage is determined by an engagement of the latch 24 with a stop 27 (Fig. 4) at one end of a cut-away portion in the periphery of a split collar 28 clamped upon the liange 26. By loosening this collar the position of the shoulder forming the stop 27 may be varied relative to both the slot 25 and pins 19 and 22. The stop thus formed determines the next. to the widest feather which extends between the points b-c and fg, Fig. 5. It will be observed that the latch constitutes a single Ymeans for selecttively engaging the two intermediate stops.

The latch 24 is acted upon by a coiled spring 29, clearly shown in Fig. 3, which operates to 'swing the hand lever 18 upward and moves the latch inward. When the latch 24 s held within the slot 25by the spring 29 the rock-shaft 15 is-locked against movement in either direction, but on depressing the hand lever 18 the latch 24 is released. The position assumed by the edge gage is determined by t-he amount of depression given the lever and the direction in which it is moved. 1f the lever is depressed only a sufficient amount t-o withdraw the latch 24 from the slot 25 and is moved rear ward, it will encounter the stop 27 upon the collar 28 and in order to move the lever 18 farther rearward, it is necessary to further depress the lever so as to move the latch below the plane of the lower face of t-he collar 28. After this has been done, the lever 18 may be moved rearward until the pin 22 engages the stop face n. By maintaining the latch in this plane of movement the lever may be moved forward until the pin 19 engages the stop face m.

In operating upon a sole, as it is necessary to start the out with the greatest width of feather to be used, the handle 18 would, before the machine is set in operation, be moved to a position with the pin 22 in en gagement with the stop face n. The pres sure of the latch 24 upon the collar 28 serves to retain the gage in its selected position of adjustment. The ywidth of feather desired at the shank is the next to greatest width and, therefore, as the shank of the sole is fed past the lip forming cutter, the handle 18 is moved forward until the spring 29 causes the latch 24 to be lifted into the cutaway portion of the collar 28 where it is held in engagement with the stop 27. As the ball of the sole is turned the desired width of feather falls olf to the narrowest width desired and, therefore, as the feed of the sole carries the ball beyond the lip forming cutter, the handle 18 is depressed so as to move the latch below the collar 28 and is quickly thrown forward t-o a position with the pin 19 into engagement with the stop face m. At about the time the point upon the sole corresponding to the tip line passes the lip forming cutter, the handle lever 18 is moved rearward again until the latch 24 snaps into the recess 25 and this gives the desired width of feather around the toe. The width of feather at the other side of the forepart, the shank and the end of the cut correspond in width to the same parts on the opposite sides of the sole as already described.

While the invention has been illustrated and described as applied to a channeling machine of a particular type, it should be distinctly understood that it is not limited in its application to this type of machine, but may be used in connection with any channeling machine wherein similar objects are to be attained.
