Definitions
- This invention relates to stock fitting machines and more particularly to such machines for performing some of the operations required to'fit themarginal portion of boot and shoe soles.
- Theohject of the present invention is to improve the construction and mode of operation of machines of the general type of those referred to, having particular reference to the setting of lips on pointed-toe soles.'
- a feature of the invention relates to an improved sole feeding mechanism which provides a positive rotation of the support for holding the sole in position for the operation thereon of the lip setting or other tools acting on its margin and which is so designed that inequalities in the thickness of the sole will not cause a loss of function.
- Another feature which relates more particularly to operations upon pointed-toe soles, contem- 1919. Serial No. 287,009.
- a third feature relates to improved mechanism for enabling the inside tool, of a pair of lip setting tools, to maintain its position under the lip when crossing the slit made in the lip of a pointed-toe insole, and sometimes others, to insure that the entire length of the lip will be raised and set in the position desired.

- the machine in its illustrated embodiment performs a lip raising and setting operation upon a double lipped sole, like the machine disclosed in my prior Patent No. 1,213,770, dated January 23, 1917.
- the present ma chine is provided with two gn'essure or lip setting rolls 10 and 12 that respectively engage the inner and outer lips of a sole as the lips are fed between them. These rolls are driven at the same surface speed and the roll 12 is carriedby the mainsha ft 14 of the machine.
- Theroll 10 is urgedtoward the roll 12 by means of a coiled spring 16 that acts on thefree end of its supporting arm or carrier 18, which is pivoted at 20 on the machine frame.
- the lips of the sole are raised in advance of their engagement by the pressure rolls 10 and 12 by means of lip turning tools or plows 22 and 24, which respectively act on the inner and outer lips of a double lipped sole.
- the sole is held in position with its lips between the pressure rolls, by means of a work positioning roll 26 which engages the unlipped face of the sole as shown in Fig. 5.
- This roll 26 is mounted upon the free end of an arm 28 which is pivoted at 30 011 the frame of the machine and 1s urged in a direction to maintain the roll 26 in yielding engagement with the unlipped face of the sole by a torsion spring 32 (Fig. 2) connected to the arm 28 by a link 34:.
- the work positioning roll 26 and the pressure roll 10 are adapted to be swung out of operative engagement with the sole by means of a foot treadle mechanism (not shown) at the base of the machine, which mechanism is connected to a rock-shaft 36 (Fig. 1) journaled in the machine frame, through a treadle rod 38 and an arm 40 secured to said rock-shaft.
- the rock-shaft is operatively connected to the arm 28 to move the roll 26 away from the sole against the action of the spring 32, by means of an-arm 42 secured to .the rock-shaft 36 and provided at its free end with a pivoted block 44, which is engaged by a yoke 46 on the end of an arm 48 integral with the positioning roll arm 28.
- the rock-shaft 36 is operatively connected to the carrier 18, on which the pressure roll 10 is mounted, by means of an-arm 50 secured to the rock-shaft, the end of: which arm engages the lower end of a foot 52vsecured to said carrier 18.
- the pressure roll 10 which engages the inner lip is cylindrical and of relatively small diameter so as to enable it to engage the lip at its extreme tip on the most pointed-toe sole desired to be operated upon. It is requisite that the surface speeds of the rolls 10 and 12 be the same in order to feed the sole steadily, but the small diameterof the roll 10 requires a. more complicated driving train than is used in said patented machines. Furthermore any change in the diameter of the roll requires a corresponding change in the driving mechanism. In order to provide for a rapid substitution of rolls of varying sizes, the roll 10 is so mounted that both it and its driving mechanism can be bodily ren'ioved without dismantling the machinev To this end the roll is formed on one end of a stud shaft 54 (Fig.
- the stud-shaft 54 is driven to rotate the roll 10 at the same surface speed as the roll 12 by means of a gear 58 on the inner end of a counter-shaft 60 which meshes with one member of a step gear 57, loosely mounted on a pin 59 threaded in the bracket 68 hereinafter described, the other member of which meshes with a gear 61 on the stud-shaft 54.
- the stud-shaft 54 is retained in the hanger 56 by n'ieans of the gear 61 on its rear end and a collar 58 on its forward end at the rear of the roll 10.
- the counter-shaft 60 is journaled in the carrier 18 (Fig. 1) and is driven by a spur gear 62, fixed to its rear end below the pivot 20 of said. carrier, which meshes with a spur gear 63 carried by the main shaft 1 1.
- the inside plow and roll are lifted slightly above the supporting roll 12 to place them in a position to ensure an engagement of the plow beneath the extreme end of the portion of the lip on the other side of the slit at the tip of the toe. when the sole is again fed forward.
- Fig. 3 shows a sole after it has been swung with the plow 22 and roll 10 at the extreme end of the half of the inner lip first acted upon. that is to say, along one side of the sole. in which position the plow slightly overlies the end of the unset half of the lip along the opposite side of the $016. This is the condition which the present invention aims to overcome. Obviously if the sole is fed forward with the tools in the position shown in Fig. 3, the plow would ride on top of the lip and since the setting roll follows the plow the second half of the lip would not be raised...
- Means is therefore actuated sufficiently to effect the raising of the plow 22 and pressure roll 10 the required amount to clear the end of the second half of the lip formed by the slit b-without retracting the positioning roll.
- This raised position is indicated by dotted lines on-Fig- 3, it being understood thatbefore the turn is made the treadle is depressed to raise the roll 10, the sole is swung while the roll is raised and then just before the" sole recommences its advance the treadle' is released thus dropping the pressure roll to its normal position with relation to the supporting roll 12, during which downward movement the plow 22 passes beneath the lip end, that is, into the channel and between the lip and the body of the sole. It will be observed that the provision for loose play between the lever arms 42 and 48 enables the positioning roll spring 32 to remain active during this period and therefore the lip is continually held firmly in position to be properly acted upon. 7
- the'hanger 56 which supports the roll is adjustably mounted, being provided at its upper end with a guide way 64, (Figs. 4 and 5) which is in'sliding engagement with a. horizontal guide bar 66 forming a part of a bracket 68 secured to the carrier 18 by screws as shown in Figs. 2 and 4.
- the hanger is held in adjusted position on said guide bar by set screws 7 2.
- the hanger 56 is split and held together by a binding screw 70 thus providing for ready removal of the shaft 54 carrying the pressure roll 10.
- the plow 22 is adapted to be adjusted relatively to the p low: 24 and the positioning roll 26 and may be secured in adjusted position by means of a cap screw 74 which extends through a slot in a horizontal portion of the shank of the plow and is threaded into the guide bar 66.
- the plow 24 is similarly adjustable by means of a like mounting as shown in Fig. 2. Attention is called to the particular shape of the shank of the plow 22. As best shown in Figs. 2 and 5 this shank is bent or bowed inwardly as at 23 to give space 'for the passage past of the raised portion of the lip when operating on the last half ofthe lip.
- a formation of the plow sha-nk is particularly useful when fitting the toe portidns'of pointed-toe insoles because of the difiiculty of bending the raised portion of the lip near the toe outward.
- Fig. 5 the section of the sole ison the line 5-5 of Fig. 3 illustrating the position of the toe portion of a sole in the machine after having been swung at the toe.
- the positioning roll 26 in the illustrated machine is driven at all times during the operation of the machine.
- said positioning roll is journaled on a stud 78 (Fig. 5) which is secured by a-set screw 80 to the pivoted arm-28, and said roll carries a bevel gear 82 which meshes with and is rotated by a bevel gear 84.
- the gear 84 is carried by a stud-shaft 86, the outer end of which is supported by being seated in asocket 88 in the arm 28.
- the inner end of the stud-shaft 86 issupported and guided by a collar 90 formed thereon which works 1n a sleeve 92 threaded into an axial bore. in the pressure roll 12.
- the stud-shaft86 is continuously driven by the engagement of a flat sided tapering tongue or key 94, formed on the inner end thereof, with a transverse slot 96 in the closed inner end 98 of the sleeve 92.
- the bevel gear 84 ismaintained in mesh with the bevel gear 82, irrespective of any movement of the work positioning roll due to inequalities in sole thickness by means of a spring 100 coiled about the stud-shaft 86 and bearing between the gear 84 and a loose washer 101 which engages the outer flanged end 102 of the sleeve 92.
- the tapering key .94 is of ⁇ sufficient length to be maintained in operative engagement with the slot 96 irrespective of the movement of the work positioning roll arm 28 while the work is clamped, and is suflicien-tly loose in the slot to allow for the necessary angular movement of the stud-shaft as the work positioning roll arm is swung outwardly on its pivot.
- the key 94 may be withdrawn from slot 96 as the arm 28 is retracted at the time that another sole is to be substituted in the machine so that the roll 26 will not be driven while such substitution is being made.
- the regular feed rolls will slip and it is therefore desirable to so design the feed mechanism that all kinds of stock may successfully be fed through the'l'nachine. Consequently the flange 102 of. the sleeve 92 is provided with short radial teeth 104 which will bite into the feather of the insole and obtain a feeding grip thereon whatever the nature of the stock. It is not intended to utilize the entire length of the teeth in feeding because this would cause a drag on the 102, that only the extreme outer ends of the feed teeth cooperate with said roll to bite deeply and effectively into the feather of the sole. 1

CHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.
STOCK-FITTING MACHINE.
Application filed April 2,
1 '0 all whom it may concern.
Be it known that I, ALBERT E. J OHNSON,
a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Stoc z-Fitting 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 stock fitting machines and more particularly to such machines for performing some of the operations required to'fit themarginal portion of boot and shoe soles.
In fitting insoles and turn soles for assembly with the upper it is requisite that the marginal lip, forming the sewing rib, be raised from its position against the face of the insole; and when the sole is to be reinforced the lip is raised to and set in an upstanding posltion to permit a proper application of the reinforcing material in the angle between the lip and face of the sole. In performing the operations of preparing the lip in the manner described and thereafter applying-reinforcing material, it has been found to be advantageous to employ machines of the general type shown in my prior Letters Patent of the United States Nos. 1,218,770, January 23, 1917; 1,217,455 and 1,217 ,456, February 27, 1917; and 1,218,- 561, March 6, 1917, since it has been demonstrated that this type of machine handles the sole rapidly, accurately and economically.
Theohject of the present invention is to improve the construction and mode of operation of machines of the general type of those referred to, having particular reference to the setting of lips on pointed-toe soles.'
In accordance with this object a feature of the invention relates to an improved sole feeding mechanism which provides a positive rotation of the support for holding the sole in position for the operation thereon of the lip setting or other tools acting on its margin and which is so designed that inequalities in the thickness of the sole will not cause a loss of function. Another feature, which relates more particularly to operations upon pointed-toe soles, contem- 1919. Serial No. 287,009.
plates the provision of a special tool for operating at the inside of the lip having a novel mounting in the frame. A third feature relates to improved mechanism for enabling the inside tool, of a pair of lip setting tools, to maintain its position under the lip when crossing the slit made in the lip of a pointed-toe insole, and sometimes others, to insure that the entire length of the lip will be raised and set in the position desired.
To the accomplishment of the object stated and such others as may hereinafter appear, as will be readily understood by those skilled in the art from the following description, the invention comprises the features and combinations of parts hereinafter described and particularly pointed out in the appended claims.
The preferred form of the invention is illustrated in the accompanying drawings, in which:
Figure 1 is a front elevation of the head of the machine;
Fig. 2 is an enlarged detail in front elevation of the operatinginstrumentalities;
Fig. 3 is a detail view showing the position of the inner lip engaging tools after the lip on a pointed-toe sole has been set approximately one half of the way round the sole, and after the sole has been swung to bring the portion of the lip which has been set above the setting tools;
Fig. 1 is a left end elevation of the head of the machine;

Fig. 6 is a. sectional view taken on the line 66 of Fig. 5; and
Fig. 7 is an end view of the pressing and supporting roll showing the feeding teeth on its face.
The machine in its illustrated embodiment performs a lip raising and setting operation upon a double lipped sole, like the machine disclosed in my prior Patent No. 1,213,770, dated January 23, 1917. The present ma chine is provided with two gn'essure or lip setting rolls 10 and 12 that respectively engage the inner and outer lips of a sole as the lips are fed between them. These rolls are driven at the same surface speed and the roll 12 is carriedby the mainsha ft 14 of the machine. Theroll 10 is urgedtoward the roll 12 by means of a coiled spring 16 that acts on thefree end of its supporting arm or carrier 18, which is pivoted at 20 on the machine frame. The lips of the sole are raised in advance of their engagement by the pressure rolls 10 and 12 by means of lip turning tools or plows 22 and 24, which respectively act on the inner and outer lips of a double lipped sole. The sole is held in position with its lips between the pressure rolls, by means of a work positioning roll 26 which engages the unlipped face of the sole as shown in Fig. 5. This roll 26 is mounted upon the free end of an arm 28 which is pivoted at 30 011 the frame of the machine and 1s urged in a direction to maintain the roll 26 in yielding engagement with the unlipped face of the sole by a torsion spring 32 (Fig. 2) connected to the arm 28 by a link 34:. The work positioning roll 26 and the pressure roll 10 are adapted to be swung out of operative engagement with the sole by means of a foot treadle mechanism (not shown) at the base of the machine, which mechanism is connected to a rock-shaft 36 (Fig. 1) journaled in the machine frame, through a treadle rod 38 and an arm 40 secured to said rock-shaft. The rock-shaft is operatively connected to the arm 28 to move the roll 26 away from the sole against the action of the spring 32, by means of an-arm 42 secured to .the rock-shaft 36 and provided at its free end with a pivoted block 44, which is engaged by a yoke 46 on the end of an arm 48 integral with the positioning roll arm 28. The rock-shaft 36 is operatively connected to the carrier 18, on which the pressure roll 10 is mounted, by means of an-arm 50 secured to the rock-shaft, the end of: which arm engages the lower end of a foot 52vsecured to said carrier 18.
The parts above described have the same general construction and mode of operation, except as hereinafter described. as in the machine disclosed in said Patent No. 1,213,770, to which reference may be had for a more detailed description.
In the illustrated machine the pressure roll 10 which engages the inner lip is cylindrical and of relatively small diameter so as to enable it to engage the lip at its extreme tip on the most pointed-toe sole desired to be operated upon. It is requisite that the surface speeds of the rolls 10 and 12 be the same in order to feed the sole steadily, but the small diameterof the roll 10 requires a. more complicated driving train than is used in said patented machines. Furthermore any change in the diameter of the roll requires a corresponding change in the driving mechanism. In order to provide for a rapid substitution of rolls of varying sizes, the roll 10 is so mounted that both it and its driving mechanism can be bodily ren'ioved without dismantling the machinev To this end the roll is formed on one end of a stud shaft 54 (Fig. 5) which extends through and is journaled in a hanger 56 sustained by the carrier 18. The stud-shaft 54 is driven to rotate the roll 10 at the same surface speed as the roll 12 by means of a gear 58 on the inner end of a counter-shaft 60 which meshes with one member of a step gear 57, loosely mounted on a pin 59 threaded in the bracket 68 hereinafter described, the other member of which meshes with a gear 61 on the stud-shaft 54. The stud-shaft 54 is retained in the hanger 56 by n'ieans of the gear 61 on its rear end and a collar 58 on its forward end at the rear of the roll 10. The counter-shaft 60 is journaled in the carrier 18 (Fig. 1) and is driven by a spur gear 62, fixed to its rear end below the pivot 20 of said. carrier, which meshes with a spur gear 63 carried by the main shaft 1 1.
In order to enable the lips of a pointedtoe sole to be properly raised and set, it is desirable in fitting the sole to make a V- shaped cut at the tip of the outer lip and a transverse slit 6 at the tip of the inner lip (Fig. A machine for performing this operation is disclosed in Letters Patent of the United States to John B. Hadaway, No. 1,087,578, dated February 17, 1914.
On account of therestricted area at the tip of a pointed-toe sole, considerable difficulty has. been experienced in properly raising and setting a marginal lip which is cut downwardly and outwardly. This difiiculty has been overcome in the machine of the present invention by constructing and arranging the pressure roll 10 and plow 22 which engage such a lip, in such manner that they are capable of acting to the extreme end of the portion of the lip on one side of the slit at the tip of the toe, without engaging the remaining portion of the lip. Just before the sole is to be swung into the position shown in Fig. 3, the inside plow and roll are lifted slightly above the supporting roll 12 to place them in a position to ensure an engagement of the plow beneath the extreme end of the portion of the lip on the other side of the slit at the tip of the toe. when the sole is again fed forward.
Fig. 3 shows a sole after it has been swung with the plow 22 and roll 10 at the extreme end of the half of the inner lip first acted upon. that is to say, along one side of the sole. in which position the plow slightly overlies the end of the unset half of the lip along the opposite side of the $016. This is the condition which the present invention aims to overcome. Obviously if the sole is fed forward with the tools in the position shown in Fig. 3, the plow would ride on top of the lip and since the setting roll follows the plow the second half of the lip would not be raised... Means is therefore actuated sufficiently to effect the raising of the plow 22 and pressure roll 10 the required amount to clear the end of the second half of the lip formed by the slit b-without retracting the positioning roll. This raised position is indicated by dotted lines on-Fig- 3, it being understood thatbefore the turn is made the treadle is depressed to raise the roll 10, the sole is swung while the roll is raised and then just before the" sole recommences its advance the treadle' is released thus dropping the pressure roll to its normal position with relation to the supporting roll 12, during which downward movement the plow 22 passes beneath the lip end, that is, into the channel and between the lip and the body of the sole. It will be observed that the provision for loose play between the lever arms 42 and 48 enables the positioning roll spring 32 to remain active during this period and therefore the lip is continually held firmly in position to be properly acted upon. 7
In order to adjust the pressure roll 10 longitudinallly relativelyto the plow 24 and the positioning roll 26, the'hanger 56 which supports the roll is adjustably mounted, being provided at its upper end with a guide way 64, (Figs. 4 and 5) which is in'sliding engagement with a. horizontal guide bar 66 forming a part of a bracket 68 secured to the carrier 18 by screws as shown in Figs. 2 and 4. The hanger is held in adjusted position on said guide bar by set screws 7 2. Preferably the hanger 56 is split and held together by a binding screw 70 thus providing for ready removal of the shaft 54 carrying the pressure roll 10.
The plow 22 is adapted to be adjusted relatively to the p low: 24 and the positioning roll 26 and may be secured in adjusted position by means of a cap screw 74 which extends through a slot in a horizontal portion of the shank of the plow and is threaded into the guide bar 66. The plow 24 is similarly adjustable by means of a like mounting as shown in Fig. 2. Attention is called to the particular shape of the shank of the plow 22. As best shown in Figs. 2 and 5 this shank is bent or bowed inwardly as at 23 to give space 'for the passage past of the raised portion of the lip when operating on the last half ofthe lip. Such a formation of the plow sha-nk is particularly useful when fitting the toe portidns'of pointed-toe insoles because of the difiiculty of bending the raised portion of the lip near the toe outward. In Fig. 5the section of the sole ison the line 5-5 of Fig. 3 illustrating the position of the toe portion of a sole in the machine after having been swung at the toe.
To assist in feeding the sole, the positioning roll 26 in the illustrated machine is driven at all times during the operation of the machine. To this end, said positioning roll is journaled on a stud 78 (Fig. 5) which is secured by a-set screw 80 to the pivoted arm-28, and said roll carries a bevel gear 82 which meshes with and is rotated by a bevel gear 84. The gear 84 is carried by a stud-shaft 86, the outer end of which is supported by being seated in asocket 88 in the arm 28. The inner end of the stud-shaft 86 issupported and guided by a collar 90 formed thereon which works 1n a sleeve 92 threaded into an axial bore. in the pressure roll 12. The stud-shaft86 is continuously driven by the engagement of a flat sided tapering tongue or key 94, formed on the inner end thereof, with a transverse slot 96 in the closed inner end 98 of the sleeve 92.
The bevel gear 84 ismaintained in mesh with the bevel gear 82, irrespective of any movement of the work positioning roll due to inequalities in sole thickness by means of a spring 100 coiled about the stud-shaft 86 and bearing between the gear 84 and a loose washer 101 which engages the outer flanged end 102 of the sleeve 92. The tapering key .94 is of {sufficient length to be maintained in operative engagement with the slot 96 irrespective of the movement of the work positioning roll arm 28 while the work is clamped, and is suflicien-tly loose in the slot to allow for the necessary angular movement of the stud-shaft as the work positioning roll arm is swung outwardly on its pivot. However, the key 94 may be withdrawn from slot 96 as the arm 28 is retracted at the time that another sole is to be substituted in the machine so that the roll 26 will not be driven while such substitution is being made.
Sometimes, as when the stock is soft and spongy, the regular feed rolls will slip and it is therefore desirable to so design the feed mechanism that all kinds of stock may successfully be fed through the'l'nachine. Consequently the flange 102 of. the sleeve 92 is provided with short radial teeth 104 which will bite into the feather of the insole and obtain a feeding grip thereon whatever the nature of the stock. It is not intended to utilize the entire length of the teeth in feeding because this would cause a drag on the 102, that only the extreme outer ends of the feed teeth cooperate with said roll to bite deeply and effectively into the feather of the sole. 1
An inspection of Fig. 4 will show that the hanger 56 is so designed that the bearing for the stud-shaft 54 is to the left of the center of the rolls 12 and 26. This throws the roll 10 slightly 'to the rear, in the line of feed, of the other rolls; and therefore gives better opportunity for manipulating said roll, in the manner hereinbefore described, just before and after the sole 'is swung at thetoe. a
