Application filed. May 3, 1915.
T 0 all whom it may concern:
Be it known that 1, WILLIAM FOWLER, a citizen of the United States, and a resident the county of Hamilton and State of Ohio, have invented a certain new and useful Machine for Trimming the Canvas of Reinforced Insoles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
In the manufacture of the greaterpart of welt shoes, insoles are used, which are rein- This canvas, after the insole is channeled and the lips are turned up, is cemented and formed to the thus prepared leather insole. In the present state of the art, the overlapping part of the can vas is trimmed flush with the edge of the insole.
The product, thus obtained, is an insole with a ragged edge, which defaces the inside of the shoe. Furthermore the trimming .knife frequently cuts the edge of the leather insoles and spoils them.
My invention has for its object to remedy these defects. 1 accomplish this end by trimming with the hereinafter described machine the overlapping canvas to a line edge of the leather insole, whereby I not only avoid the cutting and spoiling of the leather insole but also produce a clean edge of the same.
These objects I accomplish by that certain construction and arrangmeent of parts to be hereinafter more specifically pointed out and claimed, wherein I cut away the canvas, by slitting it against the surface of the insole, by means of a properly placed lmife, and
feeding devices, which accomplish a cutting of the canvas without cutting the insole.
In the drawings, Figure 1 is a right side elevation of the machine partly in section Fig. 2 1s a top plan view of the machine, on a, smaller scale. y
Fig. 3 is a front elevation thereof, on the same scale as Fig; 2.
Fig. 4: is an actual size detail side elevation of the trimming knife and feeding disks.
Fig. 5 is a perspective view of the trimlnin knife.
Fig. 6 is a perspective View of an insole with the canvas glued to it but not trimmed.
Specification of Letters Patent.
Patented May 13, 1919.
Serial No. 2 5,374.
Fig. 7 is a like view showing the canvas trimmed away by my device. 1
The machine is mounted on a stand having a top 1, forward and rear standards 2 and 3, and a basea. A shaft 5, having the idler and driving pulleys 6 and 7 respectively, is ournaled in the rear standard, and is caused to revolve by a belt 8. It has a worm 9 in mesh with a proper gear 10 at right angles thereto which imparts rotation to the driving shaft 11 of the machine. A rocker 12 is pivoted at 13 in the boss 14. on the top of the stand, and journaled in this rocker is a.
shaft 15 that has mounted on it at its forward end the vertical feed disk 16. At the rear end of the shaft 15 is mounted a pulley 17, which is driven by a belt 18 that passes over a pulley 19 on the shaft 11. Thus when the shaft 11 is revolved the shaft 15 is also revolved, which causes rotation of the vertical feeding disk, and the rocker can be moved by means which will be described below, without disconnecting the parts, because the belt will take an angular position without riding off of either pulley.
The shaft 11 is journaled in a standard 20 extending up from the base of the machine, and carries at its forward end a beveled pinion 21. This pinion meshes with a like pinion 22on a vertical shaft 23, that extends up through the top of the stand. On the top of the stand is formed a journal 2 1 for this shaft, which slraft at its other end rests in the base of the stand at 24:. Carried at the upper end of the shaft 23 is ahorizontalfeeding disk 25, that is revolved by the said shaft. The rotation of theshaft 11 thus causes both a vertical and a horizontal feeding member to rotate. The horizontal member has a smooth upper surface preferably, and the edge of the vertical member is preferably toothed so as to engage the insole when it is placed on the horizontal member as will be described.
It can be seen that the relative position of the disk 16 and the disk 25 may be changed by rocking the member 15. ,For this purfloor from the machine wher it is pivotally connected to a foot treadle 29. A depression of the foot treadle will cause the inner end of the lever to rise, and thus rock upwardly the member 15 raising the toothed feeding disk away from the surface of the rocker 1 5, VA spring 31 connected to the forward end of the locker and the boss 14" serves to hold the rockeragainst this capstan. To adjust the position of the capstan, the rocker is raised by "the foot-treadle and the capstan screwed in or out of the topyof the stand. I I I At the forward end of the rocker 15 is mounted the cutting knife which has a cut- I ting edge32, which is turned at an angle to the body portion 83 thereof. Slots 3 34:
' passes through the .are provided in the portion 33 of theknife, v
and screws 35, 35 are provided for securing the portion 33 to the rocker. These screws passthrough the slots 3t, and it is evident that the position of the knife on the rocker and with relation to thetoothed' feeding disk 16 e accomplished by sliding these slots along the screws to any "desired position.
On'apost 36 located-beneath the rocker is mounted the abutment holder 37, which may be adjusted vertically ion 7 the post "by means offtheslot 38inthe'holder and the securing screw 3 9, The abutment LO, which is to be positioned so that its outer endwill lie, on the surface ofthedisk 25 near its periphery, has a'slot 4e1"at'itsin1 '1er"end whichrides on a tongue 42'form'ed on topof the holder '37. A large headed screw43 is provided, "which 7 into the holder 37 ,thereby' providing an ad- 'justjable mounting forthe abutment.
Theoperation of'the deviceis' as follows. An'insole 44 (Fig; 6). which has been covered with canvas" l'5,which said'canvas has been turned up around the lip 46 of the insole,is placed on the revolving disk25 with the edge of the insole against the abutment 4C0; Ifjneces'sary to properly insert the insole .ui'iderneath the'disk 16, the diskmay be raised'by pressing on the'foot 'treadle. The insole is inserted under the disk 16 with its edge" press ng against the abutment plate 40, andfthe revolving feeding disks then carry the insole underneath the knife edge 7 32. Thef'position of the abutment is so' adjustedthat the'lip of the insole lying ad- Co'pies of t his patent may ts obtained for five cents each, by
7 enough to cut through th canvas covering" 45, but not to cut into the leatherof the insole. lVhen the operator guides the insole so that its edge remains in constant contact with the abutment 40, the knife will cut through the canvas at 47, leaving a rim of leather clear around the insole that is not covered by canvas.
Inasmuch as this cutting operation does not have to take place along the edge of the insole, there is not the probability of 'damaging the edge of the insole or of tearing and raveling the canvas. A perfectly clean cut edge is formed on the canvas uniform throughout, the outer or severed portion of the canvasremaining fast to the insole until it is pullel away by the operator.
"Having thus described my invention, what I claim as new'and desire to secure by Letters Patent, is
1. In a device of the character described, the combination of an insole feeding element, an abutment element to guide the edge of the insole, and 'a cutting element positioned with relation to the abutment so as to engage a canvas facing on the insole insideof the edge thereof, and positioned'with relation to the feeding element so as to cutthe canvas without cutting the insole.
2. In a device of the character described, a revolving feed disk, a revolving feed disk disposed at right angles to the first disk, at fixed knife with its edge projecting below the second disk, and an abutment positioned over'the face of the first'disk and outside of the knife to serve as a guide for the edge of an insole.
3. In a device of the character described, a table, a contact member over the table and adapted to rest on the surface of an insole, a cutter member adapted to extend a distance beyond said contact member equal to the thickness of the canvas on an insole, and a guide abutment adapted to engage the edge of the insole outside of the position of the cutting member, for the purpose described.
