- .8 Claims.
. This invention relates to trimming machines and more particularly to machines adapted to sever surplus material from the bottoms of lasted shoes. r r
In trimming the bottoms of lasted shoes an operator usually feeds the shoe manually past a trimming cutter. It is essential in this operation that the operator be able to control the widthwise location and the depth of the cutat all portions of the shoe bottom. When operating upon shoes in which the overlasted portion of the upper is secured in contact with the" surface of the insole as, for example, in cement lasted shoes, manual control of the cut by the operatorv is especially difficult because the material to be severed is located in a fiat position and there is no upstanding rib or other means on the shoe bottom. to assist the operator in guiding the Moreover, many trimming machines are of the type which requires advancing the shoe manually past the cutter. once for trimmingone' side of the shoe and again for trimming-the opposite side, the trimming cut starting at' about the tip line at each side of the shoe and usuallyterminating at the ball line. In suchcases it is necessaryv that the operator, in advancing the shoe past the cutter, be able to guide the shoe properly andto control the locationand depth of the trimming cut at each side thereof.
Accordingly, an object of the present invention is to provide improved means for guiding a shoe manually past a trimming cutter, to the end that the trimming will be uniform along both sides of the shoe'with respect to the distance of the cuts from the corresponding outlines of the shoe bottom and also with respect to the depth-of the trimming cuts.
To the attainment of this object and in accordance with one feature, the invention provides, in combination with a power operated cutter, a member arranged to serve as a depth or bottom gage for controlling the depth of the trimming cuts, and two abutments arrangedto serve as side gages for engaging opposite sides of the shoe.
The side gages or abutments are located side by tomgage is also arranged to support and shift the side gages or abutments. in the manner described.
' With the above and other objects and features in View, including also improvedflmechanism for automatically maintaining each abutment in its operative position relatively to the cutter, the invention will now be described in connection with the accompanying drawings and will thereafter be pointed out in the claims.
In the drawings,
Fig.1 is a front elevation of the machine. em bodying the present invention with the base portion of the frame broken off; I
1 Fig.2 is a fragmentary sectional view taken on the line II''II in Fig. 1;
Fig; 3 is an enlarged front view partly in section showing the trimming cutter operating on a shoe bottom; and
Fig. 4 is an enlarged transverse section taken on the line IVIV of Fig. 1.
The machine comprises an upstanding frame It! having a laterally extending upper portion l2 at the end of which is formed a supporting block or head I4. Rotat'ably mounted in suitable bearings in the head [dis a shaft !6 which is rotated by a pulley l8 fastened to the inner end of the shaft, as viewed in Fig. 1. Fixed to the forward end of the shaft by a set screw 20 is a hub member 22 closed at its front end and carrying there-. on a forwardly extending pin'24 located eccentrically with respect to the axis of the shaft. The pin 24 passes through a slot 26 in the upperportion of a carrier member 28 mounted for oscillating movement on the forward end of a fixed shaft 3|! the inner portion of which is supported in a block 32 (Fig. 4) fastened to the lower side of the head I 4, the shaft being secured to the block by anut 34.
The eccentric pin 24' carries thereon between a pair of roller bearings (not shown) a slide block 35 of usual construction which rides on adjustable gibs 36 in the slot 26 and which, when the shaft I6 is rotated, causes the pin 24 to oscillate the carrier member 26 about the fixed shaft 30. The portion of the carrier member surrounding the shaft 30 likewise carries a roller bearing 31 (Fig. 4) for reducing friction between the moving parts, the roller bearing being secured within a cover 38 by a nut 39.
The lower end of the carrier member 28 has two downwardly projecting arms 49 extending away from each other at an angle of substantially 45 and having secured to their lower ends by screws 44 an arcuate trimming knife or cutter 42 provided with a cutting edge 43. The cutting edge 43 of the cutter, which is toward the operator as viewed in Figs. 1 and 3, is scalloped, as shown in Fig. 4, and the outer surface of the cutter is ground cylindrical, as indicated at 4 .3 in Fig. 4, to facilitate the cutting action of the cutter while permitting the cutting edge 43 to execute a scooped cut in a substantially fiat plane without digging into the insole.
The upstanding portion of the frame H] has secured by screws to its forward side a plate provided with a vertical slot or guideway 52 in which is mounted for heightwise adjustment relatively to the plate a substantially horizontal block 54, the block being secured to the plate by a screw 56 passing through a slot 5? (Fig. 2) in the frame and plate 50.
The block 54 is provided with a horizontal groove 58 (Fig. 2) in which a bar 60 is arranged to slide lengthwise and is maintained therein by a cover plate 62 afiixed to the block. As viewed in Fig. 1, the left-hand portion 6 of the bar 68 extends across the shoe A and behind the cutter 42 and its lower surface, which is only slightly above the level of the lowest point of the cutter, is arranged to be engaged by the upturned bottom of the shoe to control the depth of the cutting. Moreover, this portion of the bar is also utilized to carry two underslung. side gages or abutments 66 spaced one from the other a distance slightly greater than the widest part of the widest shoe to be trimmed. Consequently any shoe may pass freely between them. The side gages are shown as circular rolls or disks and they are freely rotatable on pivot studs 68 by which they are mounted on the bottom of the horizontal .bar. These pivot studs having eccentric screw shanks l0 and are secured to the bar by nuts H and are effective, when turned, to adjust the side gages toward and from each other. When the bar 60 is shifted to the right, as in Fig. 1, the righthand side gage B6 is retracted to clear the shoe while the left-hand side gage stands in its operative position, but when the bar 65] is shifted to the left, it shifts the left-hand side gage so that it clears the path of the shoe and it simultaneously locates the right-hand side gage in an operative position.
Since the crossbar 6D has fixed limits of shifting movement, the individual adjustment of the side gages or abutments 66 afforded by the eccentric studs 68 provides for regulating the width of the margins of upper material remaining after the surplus portions have been severed therefrom. As the parts are shown in Figs. 1 and 3, the lefthand abutment 66 is in a position to guide the shoe A past the cutter to permit the latter to operate on the left-hand marginal portion of the upper. After the cutter has trimmed this side of the shoe, the left-hand abutment 66 may be shifted out of its operative position and the righthand abutment shifted laterally of the path of the shoe into a position in which the right-hand side of the shoe may be placed against this abutment to permit the cutter to operate on the righthand marginal portion of the shoe bottom.
The shifting of the side gages or abutments laterally of the cutter is accomplished by a treadle l2 adjustably connected by a rod 14 to an angle arm lever l6 pivoted to a lower portion of the frame 10 by a stud "l3 and having an upwardly extending 86 which is pivotally connected to the bar 66 by a screw 82 passing through a slot in the end of said arm. In order to limit the lateral movement of the bar to an amount that will shift each abutment 66 alternatively into and out of an operative position which is predetermined with respect to the cutter, the bar has a stop 84 secured to its upper side by a screw 85, the stop serving to limit shifting movement of the bar toward the right, as viewed in Fig. 1. The shifting movement of the bar in the opposite direction or toward the left is limited by contact of the arm Bil with the right-hand end of the supporting block 54. The construction is such that the movement of the bar between these two stops shifts the abutments 66 respectively into or out of the desired operative positions relatively to the cutter 42.
It is desirable that each abutment should be maintained against movement out of operative position during the trimming operation on the side of the shoe which the particular abutment is guiding past the cutter. Accordingly, there is provided on the lower'side of the bar 60 a pair of indentations or notches 88 and 89 (Fig. 1) located in a predetermined spaced relation to each other. The block 62 is provided with a cylindrical boss 90 on its lower side in which is mounted a compression spring 92 retained in the boss by a screw 94 and acting against a pin 96 having a rounded. end arranged to snap into one of the notches 88, 89 when either notch registers therewith. The location of the notches 83, 89 on the bar 59 is such that, when the left-hand notch 83 is engaged by the spring pin 96, the left-hand abutment 66 will be in an operative position, as shown in Figs. 1 and 3. The pin 95' acts to maintain the bar and'the abutment in an operative position until they are moved out of this position by manual operation of the treadle I2 by the operator to move the arm Bil againstthe end of theblock 62 and thus to bring the right-hand notch 89 into registration with the pin 96, at which time the right-hand gage 66 will be located in its operative position so that the right-hand margin of the shoe may be operated upon by the cutter.
As pointed out above, the machine is adapted particularly to sever surplus material from the overlasted marginal portion of an upper which lies flat against the surface of the insole of the shoe as, for example, where the upper has been lasted to the insole by cement and has no upstanding portion which could be trimmed 01f without danger of damaging the insole. The cutter 42 is arcuate in shape and executes a scooped cut in removing this surplus material from the inner margin of the upper. Moreover, as stated above, the cutter has a cylindrical outside surface at, and adjacent to, its cutting edge which acts to prevent the cutter from digging into the insole. In order, however, that the operator may be able to control the depth of the trimming cut, it is necessary that the shoe be guided and controlled heightwise of the cutter as well as widt-hwise thereof. In the present construction this is accomplished by arranging the lower side of the bar member 60 in a heightwise position which is slightly above the level of v the lowest point of the cutting edge of the cutter.
heightwise position of theshoe bottom during the trimming operation. It will be seen, moreover, that the bar 60, in conjunction with the abutments 66, provides means whereby anyr'olling or tipping movement-of the shoe may be controlled as desired by the operator. In other words, the abutments 66 and the support or rest afforded by the bar 60 permit the operator to control at will the angle at which the shoe moves past the cutter and thereby to gage the location of the material trimmed from the shoe bottom as well as the depth of the trimming cut.
In using the illustrated machine the operator presents the shoe A to the cutter by placing the toe end of the shoe bottom against the lower side of the crossbar 60, and one side of the shoe against the proper side gage 66 then in its operative position. While moving the shoe toe foremost between the-side gages or abutments he may raise or lower its heel end to regulate the depth of the cutting as controlled by the crossbar, to
the end that the operating segment of the cutting edge 43 will be tangent to the insole, as shown in Figs. 3 and 4. After feeding the shoe tosever the surplus material from the margin at one side, he will remove the shoe, shift the side gages to locate the opposite gage in operative ming surplus material that stands up from the 1 insole, as in a shoe in which the lasting margin of the upper is side-lasted with cement and temporarily secured with staples to a rib or lip on the insole. In trimming a shoe of this type, the cutter will sever the rib or lip of the insole preferably below the staples while removing the surplus material of the upper, thereby leaving the bottom of the forepart virtually smooth and even to receive a filler and an outsole.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
