Patented June 28, 1932 UNITED STATES PATENT OFFICE CHARLES E. HOOD, OF LYNN, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY MACHINE FOR OPERATING UPON SHOES Application filed. March 19, 1928. Serial No. 262,804.

The invention relates to machines for op erating upon shoes and while in certain aspects is of more general application, is herein disclosed as embodied in an inseam sewing machine for sewingtogether the Welt, upper and insole of a welt shoe in which mechanism is also included for treating by slashing that part of the welt which is to be laid about the toe of the shoe. In the machine herein illustrated as embodying the present invention, mechanism similar in many respects to that disclosed in the application of Andrew Eppler, Serial No. 608,321, filed December 21, 1922, upon which Patent No. 1,683,660 issued dated September 11, 1928, is provided for rendering operating devices, such for instance as welt slashing devices, active and inactive, which mechanism is thrown into operation upon starting the machine and is adjustable to vary the start of the welt slashing with relation to the throwing in of the mechanism so that the mechanism is uniformly rendered active upon starting the machine while the start of the slashing is varied in accordance with the length of the shoe to cause the slashed portion of the welt to register with thetoe of the shoe being operated upon.

In carrying out the invention, means have so been provided which act automatically when the shoe is placed in the machine to adjust the mechanism for rendering the operating devices active and inactive in accordance with the size of the shoe. As herein disclosed, these means comprise a shoe contact member which is displaced by placing a shoe in the machine and acts to adjust the welt slashing controlling mechanism in accordance with the size of the shoe being operated upon, so that the start of the welt slashing operation is varied with relation to the starting of the machine to cause the slashed portion of the welt to register with the toe of the shoe. This member which is displaced upon placing a 43 shoe in the machine to adjust a controlling mechanism in accordance with the size of the shoe, embodies a feature of the invention which in its broader aspects isapplicable to slice making machines generally in which it n maybe desirable to adjust an operating or controlling mechanism in accordance with the size of the shoe being operated upon.

Other features of the present invention more particularly applicable to welt slashing mechanisms in'welt attaching, machines consist in an improved mechanism for operating the welt slashing knife and in a mechanism for supporting and guiding the welt to permit a regulation of the width of cut made by the knife without any substantial change in the depth thereof.

The several features of the invention consist in the devices, combinations and arrangement of parts hereinafter described and claimed, and together with the advantages to be obtained thereby will be readily understood by one skilled in the art from the following description taken in connection with the accompanying drawings, in which Fig. 1 is a side elevation of an inseam sewing machine to which the preferred form of the invention has been applied; Fig. 2 is a View on a somewhat larger scale of the welt slashing mechanism illustrated in Fig. 1; Fig. 3 is a view in front elevation of the parts shown in Fig. 2 Fig. 4 is a plan view partly in section taken on the line 4-4 of Fig. 2; Fig. .5 is a detail view of the welt slashing lever and the connections therefrom for actuatin the mechanism for rendering the welt slas ing devices operative to slash the welt for a limited period; Fig. 6 is a view similar to Fig. 2 illustrating the parts in positions taken after the welt slashing operation when the shoe contact member is being moved out of operating position; Fig. 7 is a detail view of some of the parts illustrated in Fig. 6 in position after a new shoe has been inserted in the machine; Fig. 8 is a detail sectional view taken on the line 8-8 of Fig. 2; Figs. 9, 10, and 11 are respectively a right side elevation, a rear elevation, and a left side elevation of the welt guide for moving the Welt into and out of operative position in thepath of the reciprocating weltslashing knife; Figs. 12 and 13 are detail sectional views of a welt showing the depth of the welt cut during the slashing. operation for different adjustments of the welt support; Fig. 14 is a detail view of the ratchet wheel and spring which form a portion of the mechanism for throwing the welt slashing devices into and out of operation; Fig. 15 illustrates particularly the connection between the ratchet wheel illustrated in Fig. 14 and the actuating cam for throwing the welt slashing devices into and out of operation; and Fig.16 is a detail view of the cam for timing the operation of these devices in accordance with the size shoe being operated upon by the machine.

In the drawings the invention is shown applied to the sewing machine for attaching a welt and upper to the insole of a welt shoe which is shown and described in Patent No. 1,260,527, March 26, 1918. This machine is provided with the usual stitch forming and work feeding devices including a hook needle 2, an awl, a channel guide 6, a looper 8, and a welt guide 10. The machine isprovided with a driving and stopping mechanism which may be the same in construction as that shown and described in Patent No. 1,099,326, June 9,1914, and is controlled from a treadle through the rod 12 as is usual in this type of machine.

The mechanism for treating that part of the welt which is to be laid about the toe of the shoe consists of welt slashing devices and a mechanism for rendering them active and inactive which when thrown into operation causes the welt slashing devices to slash the welt at the proper time during the sewing of the seam and during a predetermined number of stitch forming and work feeding cycles, and then to become inactive and to remain so until the mechanism is again thrown into operation. The welt slashing devices are aranged to act on the welt between the welt guide 10 and the welt guiding and measuring roll 14 and at a distance from the sewing point substantially equal to the distance from the heel-breast, or point where the in seam begins, to the toe portion of the shortest shoes which are to be sewed upon the machine. The slashing devices comprise a slashing knife 16 which is continuously reciprocated during the operation of the machine and a welt support mounted upon a slide 18 which is vertically movable to move the welt either into or out of the path of the slashing knife as will be hereinafter described. The slashing knifeis arranged to out across the welt in a path oblique to the plane of the welt and the knife blade is inclined rearwardly, the construction and arrangement being such that the knife enters the flesh surface of the welt at or near the groove and cuts across th welt towards its outer edge to form a slit inclined rearwardly to the surface of the welt, and opening on the outer edge of the welt. The relation of the knife to the welt while cutting the slit in the welt is clearly shown in Fig. 4. Due to the angle at which it is necsssary to place the welt support in the machine in order to roperl guide the welt to the welt attaching devices, the welt slashing knife must be reciprocated in a plane which renders difficult the provision of a simple and efficient mechanism for supporting the knife and actuating it from the cam shaft of the machine. The illustrated machine is provided with a simple and efficient mechanism for supporting and actuating the welt slashing knife and this mechanism is arranged so that the mechanism for moving the welt into and out of the path of the knife can readily be actuated from the knife reciproeating mechanism. In the illustrated construction, the knife is carried on one end of a knife supporting lever 20 loosely mounted on a pivot shaft 22 which is set at such an angle in the machine as to cause the knife to be reciprocated in the desired plane. The lever 20 is actuated directly from a cam disk 26 provided with a cam groove engaging a roll 24 mounted on the other end of the lever. The cam 26 is driven from the main cam shaft of the machine through connections which include a shaft 28, a shaft 30 to the lower end of which the cam 26 is secured, and intermeshing bevel gears 32 and 34.

The welt guideway or support for holding the welt in position to be slashed by the knife and for moving the welt into and out of the path of the knife comprises a support 36 which is adjustably secured as hereinafter described to the vertical slide 18. The welt is held on t 1e support 36 by means of a bracket 38 which is mounted to slide vertically on the support 38 and is provided with two overlying fingers 39 which form a side and top guide for the welt. The bracket 38 is held in position on the support 36 and may be adj usted up and down manually to accommodate different thicknesses of welt by means of a small shaft 40 rotatably mounted on the support 36 and fitted at its outer end with a knurled head to permit it to be readily manipplated by the operator. A cross piece 42 is secured to the inner end of the shaft 40 and carries a pin 43 eccentric to the shaft 40, adapted to engage in a horizontal slot 44 formed in the bracket 38. The shaft 40 is normally held against rotation to lock the bracket 38 in adjusted position by the en gagement of teeth formed on the cross piece 42 which are adapted to engage corresponding teeth 48 formed on the support 36. The teeth are normally held in mesh by means of a. compression spring 50 coiled about the shaft 40 between the support 36 in which the shaft is journaled and the knurled head. lVhen it is desired to change the adjustment of the bracket 38 the shaft 40 is forced inwardly against the pressure of its spring 50 to disengage the interlocking teeth and may be then turned freely to adjust the bracket. An edge guide is provided to engage the inner side of the welt which comprises a lever arm 52 provided with a welt contact plate 54 and loosely mounted on a pin 56 on the support 36. The lever arm 52 and contact plate 54 are pressed yieldingly against the welt to hold it in position by means of a tension spring 58 which is secured to an arm 60 formed on the hub of the lever 52. The movement of the lever 52 and contact plate 54 under the pressure of its spring 58 is limited by means of an adjusting screw 62 mounted on the lever 52 and engaging at its inner end with the support 36. A downwardly projecting arm 61 forms a convenient means for manually moving the lever 52 and plate 54 to permit threading the welt through the welt guideway.

Since it is sometimes desirable to change the length of the slit which the knife makes in the work, the support 36 is secured to the welt supporting slide 18 so as to be capable of an angular adjustment by means of a screw 63 in the slide 18 which engages with a curved slot formed in the support 36. This slot is curved in such a manner that for any position of the support 36 with relation to the slide 18; the right lower corner of the welt as viewed in Fig. 10, will always remain in the same position, so that the maximum depth of the cut into the work will always be the same, while the length of the cut across the face of the welt will vary for the different positions of the support 36.

The mechanism for raising and lowering the welt supporting slide 18 to control the operation of the welt slashing devices by rendering them active and inactive comprises a cam groove 64 formed in a cam disk 65 mounted on a fixed stud 66 at the back of the machine and engaging a roll at the upper end of a lever arm 68 mounted on one end of a pivot shaft 70. Upon the other end of the rock shaft a lever arm 7 2 is mounted the hub of which is rigidly connected to the hub of the lever arm 68, and the lever arm 7 2 is connected by a link 74 with a lever 76, the forward end of'which is connected through a link 7 8 with the slide 18. Inasmuch as the cam roll is positively guided within the cam groove 64, the position of the welt with relation to the slashing knife is at all times accurately controlled by the cam. When the lever 68 is in engagement with the high part of the cam as indicated in Fig. 1, the welt will be held in the path of the knife 16 so that the knife will act to slash the welt and when the lever is in engagement with the low part of the cam the welt will not be slashed although the slashing knife continues to reciprocate.

The mechanism for rotating the cam 65 is thrown into operation upon starting the machine. A partial rotation only is given to the cam, however. so that the rotation of the cam ceases after the welt slashing mechanism has been thrown out of operation and the cam is held in its advanced position until the completion of the sewing operation. Means are provided whereby the initial position of the cam 65 may be varied and thus the cam may operate to render the welt slashing mechanism active immediately upon starting the machine or may cause the welt slashing mechanism to be'rendered active after the machine has made a number of stitch form-5.

ing cycles varying with the size of the shoe which has been placed in the machine. The mechanism for rotating the cam 65 is actuated in timed relation to the rotation of the cam shaft through connections from the reciprocating welt slashing lever 20, best shown in Figs. 4, 5 and 8. These connections comprise an incomplete ratchet wheel which is formed integral with the cam disk 65 and a pawl carrying actuating lever 82 loosely mounted on the fixed shaft 66 and connected to move with the knife supporting lever 20 through connections which comprise a short spindle 84 rigidly mounted on the knife supporting lever 20 and provided with ballshaped end which engages suitably shaped sockets formed in two small plates 85 loosely mounted to slide in a groove 87 formed in the lever 82. An actuating pawl 86 is pivotally mounted at 88 on the actuating lever 82 and during the operation of the machine is held in contact with the ratchet wheel 80 by means of a small compression spring 90 which engages with a tail formed on the rear end of the pawl. A detentpawl 92 mounted at 94 on the machine frame serves to hold the ratchet wheel and cam disk 65 in-the position to which they are advanced by each succeeding movement of the actuating pawl 86. The distance through which the cam disk 65 is rotated before its rotation ceases is determined by a smooth portion 96 formed on the ratchet wheel 80 onto which the pawl 86 rides after the cam disk has been rotated far enough to render the welt slashingmechanism inactive. A coil spring 98 secured at one end to the fixed shaft 66 and at its outer end to a point on the ratchet wheel 80 acts to resist the movement of the ratchet wheel and cam disk 65 while being rotated by the pawl 86 and tends to return the wheel and disk to their initial position.

An important feature of the present invention is embodied in mechanism which acts automatically upon placing a shoe in the machine to position the cam disk 65 so as to time the start of the welt slashing operation in accordance with the size of the shoe being operated upon. This mechanism comprises a shoe contact lever 100 secured to one end of a rock shaft 102 and provided at its lower end with a plate 104 adapted to come into contact with a shoe placed in the machine. At its other end the shaft 102 is provided with a short lever arm 106 which is connected by means of a link 108 to a lever arm 110 mounted on a pivot shaft 112. On this rock shaft is also mounted a lever arm 114 rigidly connected to the lever arm 110 and arranged to engage with one of a series of stop shoulders or notches 120 formed on a stop disk 116 which is mounted to turn with the ratchet wheel 80 and cam disk 65. A tension spring 118 secured at one end to the shoe contact lever 100 and at its other end to a point on the machine frame tends to swing the lever to the left as viewed in Fig. 3 and at the same time acts to hold the lever arm 114 in contact with the stop disk 116.

In order to provide for a manual initial adjustment of the stop disc 116 with relation to the cam disc the stop disc is mounted on the hub of the cam disc, as best shown in Fig. 8 and the two discs are fastened together by a locking pin 117 engaging one of a series of holes 119 in the hub of the disc 116, and one of a corresponding series of holes 121 in the hub of the disc 65. By rotating the disc 116 with relation to the disc 65 and then placing the pin 117 in holes 119' and 121 which have been brought into register. the stop disc can be given the desired initial manual adjustment with relation to the cam disc.

When the machine is at rest, the parts are in the position illustrated in Figs. 1 and 2, i which position the pawls 92 and 86 areheld out of engagement with the ratchet wheel 80 as will be hereinafter described, and the lever arm 114 is in engagement with the stop shoulder 120 nearest the axis of the stop disc. Upon placing ajshoe in the machine, the shoe contact lever is displaced or forced backwards to the right as viewed in Fig. 3, against the pressure of itsspring a distance which corresponds with the size of the shoe which is being presented to the sewing mechanism and the lever 114 is at the same time raised a corresponding distance so that the stop disc 116 and the associated cam disc 65 and ratchet wheel 80 are allowed to move in a clockwise direction under the influence of the spring 98 until the lever arm 114 comes into contact with that one of the series of stop shoulders 120 which will position these parts properly for operation during the sewing of a shoe of the size which has been placed i nthe machine. The lever arm 114 is provided with a series of ratchet teeth 122 which, upon starting the machine, are engaged by a detent pawl 124. mounted on the fixed pivot 66. A tension spring 126 tends to hold the pawl 124 in engagement with the ratchet teeth 122. To regulate the movement of the cam disc 65 and ratchet wheel 80 under the influence of the spring 98 a friction brake in the form of a spring plate 127 is arranged to bear against theface of the stop disc 1 16.

lVhen the machine is started by depressing the starting treadle and drawing the rod 12 downward, the pawls 92 and 86 engage the V teeth of the ratchet wheel'and advance the ratchet wheel and cam disc 65 against the tension of the spring 98 until the pawl 86 rides -onto the-blank surface 96 when forward movement of the ratchet wheel and cam ceases and these parts are held stationary by the stop pawl 92. During this partial rotation of the ratchet wheel and cam and at a time varying with the initial adjustment made by placing a shoe in the machine, the end of the lever 68 passes into the high part of the cam grove 64 and the welt slashing devices are rendered active to slash the welt, after which the end of the lever rides off the high part of the cam groove and the slashing ceases. During this partial rotation of the ratchet wheel and cam also a cam surface on the disc 116 raises the lever arm 114 into its highest position and swings the contact plate 104 to the right as viewed in Fig. 3 into a position where it will not interfere with the manipulation of the shoe by the operator. The parts remain in this position with the slashing devices inactive and with the cam disc 65 in its advanced position until the machine is stopped by the'release of the treadle and the upward movement of the rod 12. At this time, the pawls 86 and 92 and also the pawl 124- for holding the pawl lever 114 in raised position are lifted out of contact with the ratchet teeth so that the ratchet wheel and attached cam disc 65 are returned to their initial position by the spring 98, and the levcr 1.14 being released drops into its low position, permitting the shoe contact lever 100 to move forward under the pressure of its spring 118. F or the purpose of disengaging the pawls, a vertically situated rod 128 is provided connected at its upper end to a lever arm 130 which is formed integral with the hub of the pawl 92, the lower end of the rod being connected with an arm 132 secured to one end of a roclz shaft 134. On the other end of the rock shaft is secured an arm 136, see Fig. 1,which is connected with the rod 12 by collars 138 secured to the rod and engaging opposite sides of the arm. When the rod rises upon the release of the treadle, the arms 132 and 136 are rocked to raise the rod 128 so that its upper end causes the lever arm 130 and the pawl 92 to rotate to lift the pawl from the ratchet wheel. This movement of the pawl 92 at the same time causes the actuating pawl 86 to be raised out of contact with the ratchet wheel by the engagement of a bar 140 secured to the pawl 92 with a pin 142 secured on the actuating pawl 86. The movement of the'pawl 92 is at the same time utilized to cause the pawl 124 to be withdrawn from contact with the ratchet teeth 122.011 the lever arm 114 through connections which include a link 144 pivoted at one end to a tail formed on the pawl 124 and at its other end connected to a tail formed on the pawl 92 by means of two nuts 146 which are mounted on the link to permit a certain amount of play between the parts.

It is occasionally. necessary, as for instance upon breaking ofthe thread, to stop and restart the machine during the sewing of a shoe. In such a case, the slashing devices should not be rendered operative in restarting the machine and means are therefore provided through which the operator may render inoperative the mechanism forthrowing the slashing devices intooperation upon start ing the machine. In the construction shown, this means comprises a horizontally situated disc 148 loosely mounted on a pivot 150 on a bracket 152 secured to the machine frame. The disc 148 is provided with a sloping cam surface 154 which is adapted to engage with a stop 156 which is adj ustably secured on the vertical link 128 by means of a set screw 158. If the operator finds it necessary to stop the machine during the attaching operation, he may rotate the disc 148 by means of a small handle 160 to bring the cam surface 154 under the stop 156 so that the link 128 is held in raised position with .the pawls 86, 92 and 124 in inoperative position when the machine is again put in operation.

While it is preferred to employ the specific construction and arrangement of parts shown and described in applying the invention to an inseam sewing machine of the type shown in the patent referred to, it will be understood that this construction and arrangement is not essential to the broader features of the invention and may be varied or modified as found desirable or best suited to the construction and mode of operation of the machine to which it is to be applied.
