Application filed August 8, 1910. Serial No. 576,038.
To ad Awim/n, 'it may concern Be it known that I, ERAs'rUs E. IVINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Lasting-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.
The presentinvention relates to certain new and useful improvements in lasting machines and more particularly to that type of .lasting machines commonly known as the hand method lasting machine.
It is desirable in lasting the better grade of shoes and in last-ing shoes in which the pulling over operation has been ineiiiciently performed, for the operator, in order to properly last the shank, to perform this step 1n the operation by hand. A spindle is commonly provided upon the bench at one side of the machine and prior to lasting one side of the shoe the operator will spindle the last, seize the margin of the upper with hand lasting pincers, at a point about opposite the ball of the last, and will then draw on the upper with a slow steady pull in a direction toward the heel and across t-he instep, such a pull being necessary to properl draw the upper at' the instep to the woo The upper at this point is generally slack and stands out from the body of the last owing to the sharp inward curvature of the last at the shank and a sharp quick pull which is suliicientto properly draw over the upper at the ball of the last, would not effectually draw over the upper at this point. After having thus stretched the upper and drawn it to the wood it is held tightly in place by the operator until the first tack has been driven by the machine at about the ball of the last. After one side of the shoe has been lasted, the last is again spindled, the margin of the upper at the opposite side of the ball of the shoe is seized by hand piucers at the instep and the upper is drawn to the .wood by stretching it over that side of the last. A tack is driven at this point and the remainder of the upper upon this side of the shoe is then lasted as before.
The principal object of the present invention is to enable the upper to be evenly and tightly drawn to the body of the last at the shank portion by mechanical means.
Vith this end in view 011e feature of the invention comprises mechanism for giving a slow upward and overdiaw movement to the plncers after the upper has been grasped at the shank portion.
A further object of the invention is to provide means which will enable the pincers of the lasting machine to properly grasp the margin of the upper and draw the upper over at the shank portion of the last when operating upon shoes in which the ed e of the upper at the shank of the shoe elther does not extend upwardly to the level of the bottom of the last or in which the upper stands out from t-he body of the lastat the shank portion.
With this object in View a further feature of the invention contemplates the provision of a movable bottom rest for the last with mechanism for automatically moving the bottom rest when the shank portion of the upper is to be drawn over into a position where the upper of the shoe may be grasped by the pincers at a point farther removed from the sole than is possible when operating upon other portions of the shoe.
Still further features of the invention will be more fully described in the accompanying pacification and defined in the appended aims.
In the accompanying drawings illustrating the preferred form of the invention, Figure 1 represents a side elevation of a lastin machine with the present invention ap lie thereto; Fig. 2 represents a right-han elevation of the machine shown in Fig. 1, with the upper portion of the driving pulley broken away, and illustrating the mechanism for moving the work support and for securing a slow movement of the pincers; Fig. 3 is a detail of the operating mechanism for the work support; Fig. 4 is a section upon the line 4 4 of Fig. 3; Fig. 5 is an end elevation of the work support shown in Fig. 3; Fig. 6 is a longitudinal section through the main driving pulley and shaft illustrating the mechanism for securing a slow movement of the pincers; Fig. 7 is a section upon the line 7-7 of Fig. 6; Fig. 8 is a sectional View taken from the line 8--8 of Fig. 6 and showing a detail of the clutch which is employed; and Fig. 9 is a detail showing the cage or retaining ring employed for holding the rolls of the clutch in place.
The resent invention is preferably illustrated 1n connection with a machine of the type shown and described in United States Letters Patent to S. W. Ladd, No. 597,821, dated January 11, 1898, but it is to be understood that the device which is thc subject of the present invention is capable of general application upon various types of hand method lasting machine, and it is not to be considered as limited in its use to the particular type of lasting machine shown in the drawings. The shoe is operated upon in this type of machine by holding the last bottom upward against the bottom rest l. The margin of the upper of the shoe is then grasped by a pair of movable pincers 3, which, after securing a firm hold on the upper, are moved first upward and then inward toward the center lino of the sole to draw it uniformly and evenly to the body of the last. The upper is then held in this position of the pincers while the tacker mechanism 4 drives a tack through the upper and secures it in position at this point, the tack being held by a tack block 2. This mode of operation is Old and well known in the art, as may be seen from an inspection of the patent to S. W. Ladd hereinbefore referred to, and forms no part of the present invention. In all previous hand method lasting machines, however, in order that the upper may be properly drawn to the wood across the instep, it has been necessary, when lasting the shank of a shoe, to spindle the last and to perform this portion of the operation with care by hand. This is due to the fact that th-epincers, in order to properly draw the upper to the body of the last at the start, must have a slower relative overdrawing movement than is provided by the ordinary pincer operating mechanism or than is needed in lasting the upper at the forepart of the shoe.
In the present machine mechanism is pro vided for giving a relatively slow movement to the pincers when drawing over the upper of the shoe at the shank, as it is found that this slow movement draws the upper to the wood more tightly and evenly than would be possible with the quick movement of the pincers which is employed in drawing over the forepart of the shoe.
In some cases when the shoe comes to the lasting machine the upper is slack at the shank and therefore the margin of the upper does not project beyond the plane of the sole as it should. In other cases, the upper stands out from the body of the last at the shank owing to improper pulling over and other causes well known to those skilled in the art. In either of these or similar cases when the shoe comes from the puller-over with the upper improperly positioned at the shank, it is necessary to provide the machine with some auxiliary means which will enable the pincers to properly seize the mar` gin of the upper at this point as the pincers ordinarily would not have the requisite movement necessary to reach the upper if the shoe were held in its normal position. In order to overcome this difficulty an auxiliary mechanism has been provided for moving the usual bottom rest upward to enable the shoe to be raised to a position where the margin of the upper may be seized properly by the pincers. The mechanism for moving the bottom rest operates preferably in conjunction with the mechanism for giving a slow move-nient to the pincers but these mechanisms may be disconnected and allow the bottom rest to be held continuously in a stationary position when so desired.
It is not desired, of course, to affect the normal speed and operation of the lasting machine during the lasting of the ball and toe of the shoe, and to this end of the mechanism for securing aslow movement of the pincers and operating the bottom rest is conveniently thrown into operation by a hand lever 5 which is attached to one end of a rock shaft 6 mounted in brackets 7 upon the frame of the machine. The rock shaft. 6 upon being oscillated slides the cam roll 8 and arm 9 mounted upon the shaft 10 longitudinally in the supporting bracket ll. The cam roll 8 engages with a plate cam 12, but it will be noted that the cam 12 comprises an outer circular surface 13 and an inner cam path 14. The cam roll, in the normal operation of the machine, ordinarily travels in contact with the outer' surface 13 and no movement downward is imparted thereto, but upon movement of the hand lever 5 by the operator the cam roll 8 is moved inwardly and engages with the cam path 14. The mechanism by which motion is transmitted fro-1n the rock shaft 6 to the shaft 10 to move the same longitudinally conveniently comprises an arm 16 sleeved to the outer end of the rock shaft and locked against rotation relatively thereto, and a forked lever 17 pivotally connected to the free end of the arm 16 and having its forked end embracing the shaft 10 and bearing against the hub of the arm 9. In order that a vertical movement of the forked lever 17 shall move the arm 9 and shaft 10 longitudinally, the lever 17 is provided with wedge-shaped surfaces 18, shown in Fig. 1, upon the face of the lever contacting with the arm 9.
The preferred form of t-he path cam is one similar to that illustrated, in which the cam produces an initial movement of the various mechanisms by engagement of the cam roll with the inclined port-ion 21 of the cam path, the cam path being next provided with a dwell 2O during which the parts are held in the position to which they have initially moved, the cam roll being then returned to its original position by the portion 1S) of the cam path, restoring the mechanisms to their normal position. The movement of the cam roll by the cam accomplishes two distinct results. Upon engagement of the cam roll 8 with the portion 21 of the cam path, the bottom rest 1 is moved upwardly and over a certain predetermined amount, and at the same time the driving mechanism for moving the pincers is automatically regulated to secure a slow movement of the pincers. lVliile the cam roll S travels through the portion 20 of the cam path, the bottom rest 1 is held in its raised position and the pineers 3, having grasped the upper, are retracted with a slow movement. Simultaneously with the pincers reaching the limit of their upward movement the cam roll engages with the portion 19 of the cam path, and the bottom rest 1 is moved down and back to its normal position, securing a further drawing over of the upper of the shoe, at the same time the slow speed is automaticallyT thrown out.
It is considered desirable to automatically return the cam roll 8 to its normal position in contact with the surface 13 of the cam 12, and to this end a project-ion 12 is formed upon the edge of the. cam 12 contacting with arm 9 and moving it outwardly upon engagement therewith. lVith this arrangement the mechanism for securing a` slow movement of the pincers will only be operative during one revolution of the driving shaft 54 unless the operator again moves the hand lever 5. It will be understood that the wedge 18 has been lowered before the completion of this revolution, as the weight of the parts at the other side of the shaft 6, from the handle 5, is sufficient to cause the wedge to drop on the release of the handle by the operator. The bottom rest l is slidably mount-ed for longitudinal movement in a box 22 and is provided upon its upper face with a toothed rack 23 which engages with an oscillatory toothed segment 24. The bottom rest 1 and supporting box 22 are mounted upon a cross-head 25, which slides in vertical ways 26 in the fra-me. A vertical movement is given to the crosshead 25 b v engagement of an oscillatory toothed segment 27 with a toothed rack 28 formed upon a projecting face of the crosshead. The frame is slotted at 28*l and .the rack projects therethrough to prevent twisting movement of the cross-head. The segment.- 27 is fixedly mounted upon a rock shaft 29 which is mounted in brackets 30 secured to the frame of the machine. The
rock shaft. 29 is operated upon movement of the cam roll S through a train of mechanism comprising an arm 31 fixed upon the outer end of the rock shaft 29 and having a link 32 pivotally connected to its free end. The link 32 is pivotally connected at its lower end to a slotted segment 33 which is fixed upon one end of a shaft 34. In order that the oscillatory movement of the shaft 29 may be varied, and, if so desired, may be entirely discontinued, the curved segment 1s attached to the shaft 34 b v means of a yoke 35, and the link 32 is adjustably secured to the segment 33 by a bolt' and nut 36. The yoke connection enables thc lower portion of the link 32 to be secured 1n the segment at. a point coincident with the axis about which the segment 33 oscillates, so that, when so secured, upon oscillation of the segmentno resultant movement will be communicated to the link 32 and rock shaft 29. The value of this feature will be appreciated when it is considered that 1n operating upon man v kinds of shoes it is only desired to secure the slow movement of the pincers and not the additional movement of the bottom rest which can be easily retained in locked position and hold the last stationary while the upper is being operated upon by the pincers. The rock shaft 34 is oscillated upon movement of the arm 9 through a system of linkages comprising an arm 37 mounted upon the hub of the arm 9 and movable therewith. The arm 37 has a link 38 connected to its free end and the link 3S is connected through a universal joint- 39 and a short rod 40 with the pivotal point 41 of a toggle. The arm 42 of the toggle is formed integrally with a sleeve 43 which is loosely supported upon the shaft 6. The sleeve 43 has an arm 44 fixed thereto and extending from the side opposite the arm 42. The arm 44 oscillates the shaft 34 through a link 45 connected to its free end and the arm 46 which is fixed to the shaft 34. The opposite arm 47 of the toggle is connected at its free end ,to a lever 48 pivoted at its central point on the frame of the machine and engagin at its upper end the head of a bolt 49 whic i is normally held inward by a coiled spring 50 bearing against a nut 51 at one end and bearing at its opposite end against a projecting lug 52 formed upon the band 53 of a friction brake mounted upon the main driving shaft 54 of the machine. A movement of the cam roll 8 and arm`9 will thus operate through the toggle to oscillate the shaft. 29 and move the bottom rest 1 upwardly, and will at the same time rock the lever 48 about its pivotal point, moving the upper end outwardly, compressing the spring 50 to tighten the brake band 53 and apply the friction brake. The movement of the rest 1 due to the oseillation of the shaft 29 will continue in a vertical direction until the free end 55 of an arm 56 contacts with the upper wall of the recess 57 into which the arm 56 projects. When the end of the arm 56 is stopped from further movement in a vertical direction, the continued upward movement of the cross-head 25 will result in oscillating the toothed segment Q4 which is fixed to the arm 5G and pivotally mounted at 5S in the crosshead 25.
The oscillation of the segment 24 will withdraw the rest 1 in the box 22 against the action of the spring 59 which is fastened atl one end to the box and at the other end to a portion of the rest 1. Upon the oscillation of the shaft 29 in the reverse direction the spring 39 will retain the free end of the arm 5G against the upper wall of the recess 57 until the rest has been forced out of the box QQ to its normal position when the movement of the rest will be vertically downward. As it is necessary for the bottom rest to be returned to its original or normal position in order that the tack may be properly driven, a pin GO is mounted in the frame of the machine extending into the recess 57 and positioned to Contact with the lower edge of the arm 56 in order that the rest 1 shall be positively forced over into its proper position before the tack is driven into the last. It will now be seen that in addition to the upward and over-draw movement of the pincers, there is also the movement of the bottom rest back to its normal position, which is the reverse of the upward movement of the pincers, so that the result is an increased drawing over of the upper at this point. The pincers are yieldably mounted so that when the strain upon the upper due to the downward movementof the bottom rest exceeds a certain amount the pincers will yield and not tear the upper. In order that the rest shall be locked and held rigidly in place during the tack-driving operation, a spring-pressed pin G1 is provided, the end of which projects into a hole in the side face of the rest 1 when in its norlnal position. The pin 6l is mounted in a slot in the frame of the machine, and is normally forced inward by a coiled spring G2. In order that the botto-m rest may be released upon its upward movement, a vertical forked finger 63 is bolted to the side of the cross-head slide 64, and has a wedge-shaped lower end G5 engaging with the head of the pin G1, so that upon upward movement of the rest 1, the wedge G5 engaging with the head of the pin 61 will force the pin outwardly and release the wor i support, allowing it to be withdrawn.
The slow movement of the pincers 8 is secured upon tightening the brake band 53, and it will be seen that this is coincident with the upward movement of the rest 1 and that the slow movement will continue during` the time that the rest is maintained in its raised position. Under normal conditions the drive shaft 54 will be driven directly from the drive pulley 66 when the brake band 53 is loose. A sleeve 67 is keyed to the shaft 54 and has a gear 68 formed integrally upon one end thereof. A second sleeve 69 is mounted loosely upon the sleeve 67 and has a gear 70 fastened thereto. The gears G8 and 70 mesh respectively with gears 71 and 72, keyed together and rotatably mounted upon a radial arm of the drive pulley G6. rThe gears 71 and 72 have a different number of teeth and will tend to drivethe gears GS and 70 respectively at different speeds. The sleeve (59 has a series of radial projecting arms 73 upon the outer ends of which is fastened the gear '70. These arms 73 of the sleeve (S9 form a portion of what is commonly known as a Horton clutch` and a cage or retaining ring 74 is loosely supported upon the sleeve (S9 and provided with a series of longitudinally projecting arms which project between the arms 73 of the sleeve 69. rThe portions of the sleeve G9 between the arms '73 and projecting beyond the same are slightly iiattened, as shown clearly in Figs. 7 and S. The arms 75 of the retaining ring 74 are provided with recesses 7G, in which are held balls or rolls 77. As thel driving pulleys GG and gears 71 and 72 are revolved, thegears (58 and 70 will tend to revolve atdifferent speeds, the gear 70 rotating faster than the gear G8, and as the brake band is normally loose, the retaining ring 74 will be allowed to rotate freely and the arms 75 of the retaining ringl 74 will be moved by the radial arms 73 relatively to the gear (38. wedging the balls 77 between the surface of the sleeve 69 and the inner flanged portion 7S of the gear G8 locking the two gears G8 and 70 against rotation relatively to (ine another. It is preferred. in order to secure a. more positive action of the clutch, to employ two sets of springs SO-Sl which bear against the arm 75 of the ring 74 and the balls 77 respectively, and tend to normally lock the clutch. Owing to the fact that the gears 71 and 72 will tend to rotate the gears GS and 70 at different speeds, t-he shaft 54 will be driven directly from the pulley 6G as soon as the gears G8 and 70 are locked to one another, in the same manner as if the pulley 66 were keyed directly to the shaft 54. l-Vhen the brake band is tightened, however, the retaining ring 74 and the gear 7() will be held against rotation and will prevent the balls 77 of the clutch from becoming` wedged into place and locking the gears 68 and 70 together. Then, as the gear 70 is held stationary, a slow rotatio-n will be imparted to the gear 68 to rotate the shaft 54 which is the result of the differential movement between the gears 71 and 72. In order that the gears may be properly inelosed from dust, and the operator protected from injury by the gearing, a shield 79 is fastened to the drive pulley and covers the various gears.
While the particulars described are well suited to one mechanical form of the invention, it is not to be understood that these particulars are essential, since they may be variously modilied within the skill of the artisan without departing from the true scope of the actual invention, as defined by the claims.
