54 Claims.

This invention relates to machines for use in operating upon the bottoms of boots and shoes and is illustrated herein as embodied in a machine adapted to form a positioning mark in a shoe sole.

It has been found desirable in performing certain operations around the bottom margin of a shoe, such, for example, as the sole-rounding or edge-trimming operations on an attached outsole, to provide a templet located in proper position on the shoe sole and to utilize this templet as a guiding means to control or determine the outline on the shoe followed by the rounding or trimming cutter. If such a templet is to be successfully used, it is necessary that the templet be located in exact predetermined position with respect to the last contours of a shoe in order that the edge produced by the cutter 'may be used as a guide for subsequent operations, such, for example, as the outseaming operation, or that the outline followed by an operating tool may present a proper appearance in the finished shoe.

An object of this invention is to provide a solemarking machine for automatically forming a positioning mark on the outsole of a shoe in a predetermined position with respect to the last contours of the shoe. In accordance with this object, one feature of the invention resides in a sole-marking machine having means for positioning a shoe laterally by engagement with the side of the toe, means for positioning the shoe longitudinally by engagement with the end of the toe, means for clamp-ing and supporting the shoe as it is being swung into position, and means for making a mark upon the shoe sole in predetermined relation to said positioning devices. Ln the illustrated embodiment of the invention, ,the means for positioning the shoe with respect to a marking tool includes a pair of arms geared together at one end and provided with rolls at their other end which engage the sides of the shoe upper adjacent to the sole to position the shoe laterally with respect tothe marking tool, and a swinging arm having a block against which the toe end of the shoe rests, arranged to engage the frame of the machine, for positioning the shoe longitudinally.

Another object of this invention is to provide improved movable shoe-supporting means constructed and arranged automatically to carry a shoe from a jacking position into a predetermined position with respect to an operating tool. To this end, another feature of the invention resides in a machine provided with a work support or jack constructed and arranged for movement into and out of operative position, the support having a normal jacking position out of operative position, and provided with power operated means acting upon initial manual movement of the support toward operative position automatically to continue the movement to present a shoe in predetermined relation to an operating tool. In the illustrated embodiment of the invention, the means for moving the shoe toward its operative position includes a continuously reciprocating drag link having means on one end for engaging the support and being normally held out of operative relation to the support by links or arms which cause the reciprocating link to be held out of engagement with the support until after initial manual movement of the support toward operative position.

Another object of this invention is to provide improved means for forming a mark of predetermined depth in a shoe sole. this invention, accordingly, resides in a machine provided with a presser constructed and arranged to engage a work piece and provided with means movable relatively to the presser member to make a mark of predetermined depth in the work piece after the presser member has come into engagement with the work piece. Preferably, and as illustrated, the presser member comprises a sliding sleeve which is constructed and arranged to engage the sole of a shoe before the marking means or prick punch is moved a predetermined distance relatively to the sleeve to make a mark of predetermined depth in a shoe sole after the presser member has engaged the shoe sole.

These and other objects and features of the invention will be apparent from the following detailed description read in connection with the accompanying drawings and the novel features of the invention will then be defined in the appended claims.

Fig. 6 is a view taken along the line VI-VI of Fig. 5.

Another feature of The machine illustrating an embodiment of the invention includes a pair of frames I6 which are mounted on a base I2. As illustrated in Fig. 1, the machine is provided with two operating heads, each being supported by the frames ID. The operating heads are identical in construction and only one of these heads will be described in detail. The front portion of the base I2 is provided with a cover I4 to permit access to the mechanism contained therein.

Mounted on a horizontally extending portion of the base I2 is an electric motor I6 which has its shaft coupled to a shaft carrying a worm I8 which in turn drives a cam shaft26 through a worm gear 22. Cams 24 and 26 are secured to the shaft 28 by any suitable means. The cam 24 has a cam track 28 formed therein in which rides a cam roller 36 secured to the lower end of a bell crank lever 32. The lever 32 is pivoted to the machine frame at 34 and controls the movement of a 'jack or work support, indicated generally by the reference character 38.

The work support 36 comprises a last pin carrying spindle 38 pivoted to the frame I8 at 46 and a swinging arm or toe rest 42 which is also pivoted to the machine frame at 46. The spindle 38 is forked at its upper end to receive a pivoted member 44 carrying a last pin 46. The pivoted member 44 is so mounted that the last pin 46 cannot tilt laterally and thus holds a shoe mounted thereon against movement about its longitudinal axis. Rotation of the pivoted member 44 is limited by a stop pin 48 which enters a depression or recess in the pivoted member 44. The last pin 46 and the spindle 38 are normally urged toward the toe rest 42 by a spring 56 which is secured at one end to the pivoted member 44 and at its other to the toe rest 42. The movement of the spindle 38 toward the toe rest 42 is limited by an adjusting screw 52 bearing against a stop 54 on the toe rest 42. The toe rest or support 42 (as shown best in Fig. 1) is provided with a longitudinal slot to receive mechanism for imparting movement to the work support 36. The upper end of the toe rest carries a substantially U-shaped plate 56 having an upper member 58 and a lower block 66. When a lasted shoe is placed on the last pin 46, the spring 56 forces the toe end of the shoe against the lower block 66 and the projecting portion of the outsole lies between the upper member 58 and the block 66 with the surface of the outsole adjacent to the block 66 resting thereon.

The mechanism for moving the work support 3.6 toward and under the operating head comprises cam and lever connections between the cam 24 and the toe rest 42. The bell crank lever 32 is forked at its upper end to receive an arm 62 which is pivoted to the lever 32 by means of a pin 64. Slidably mounted in a boss 66 on the lever 32 is a pin 68 which is normally urged outwardly under the influence of a strong spring I against a projection I2 on the arm 62. Coacting surfaces I4 on the lever 32 and the arm 62 limit the clockwise movement of the arm 62 under the influence of the spring I6. The construction just above referred to insures that a stop I6 on the swinging arm 42 will always be brought against a stop 18 on the machine frame thereby insuring that the shoe carried on the support 36 will be brought into proper position beneath the operating head 86, of the machine despite any inaccuracies in, or lost motion between, the parts of the operating mechanism. A drag link 82 is pivoted to the upper end of the arm 62. The

drag link 82 is cut away to form a recess 84 which, under conditions later to be described, is pulled down over a pin 86 extending through the swinging arm 42 under the influence of a spring 89.

The lever 32 is continuously reciprocated by the rotating cam 24 and it is necessary, therefore, to provide means under the control of the operator to prevent movement of the support 36 while a shoe is being placed on the support. The drag 1 link 82 is provided with a slot 81, through which passes a pin 88 fastened in a slotted arm 96 which is pivotally secured to the machine frame at 92. The forward end of the arm 96 is provided with cam surfaces 94 which when they are in contact with the pin 86 raise the arm 66 and the pin 88, engaging the upper wall of the slot 81, raise the drag link 82 and prevent the recess 84 from engaging the pin 86. The upper surface of the arm 90 is notched at 96 to receive the lower end of a latch pin 98. The latch pin 98 is secured at its upper end to a latch I68 which, when raised, withdraws the latch pin 98 from the notch 96 and allows the arm 42 to be moved in the direction of the arrow in Fig. 3 until the pin 86, which extends through the arm 42 and beyond the two sides thereof, is brought under the recess 84 in the continuously reciprocating link 82. The latch I08 is normally urged downwardly by a spring IIII to cause the latch pin 98 to engage the notch 96.

When the support 36 is being returned from the position shown in Fig. 2 to the position shown in Fig. 3, the forward end of the arm 96 engages a pawl-like member I02 which is pivoted to the swinging arm 42 and is held toward the arm 42 by a spring I04. The member I62 carries a pin E66 which engages a stop I68 which limits the extent of movement of the member I82 under the influence of the spring I64. The surface III] on the member I62 engages the cam surfaces 94 on the arm 96 and raises the arm 96 so that a notch M2 on the arm 96 engages the pin 86 thereby holding the link 82 out of contact with the pin 86. The arm 42 is limited in its movement to the position shown in Fig. 3 by a rod I I 4 which is pivoted at one end to the arm 42. The other end of the rod passes through an opening in the machine frame I8 and a spring H6, which encircles the rod between the machine frame and a pair of lock nuts I I8, acts as a resilient stop to limit the outward movement of the arm 42. When the latch I66 is raised the arm 42 is moved in the direction of the arrow in Fig. 3 until the pin 86 engages a projection I20 on an arm I22 which is pivoted to the frame at 92. In this position the pin 86 is located at a point where it may be caught in the recess 84 of the drag link 82. The arm I22 is forced downwardly by a pin I24 on the link 82 to move the projection I20 out of the path of 0' movement of the pin 86. The support or jack 36 is then moved as a unit to the right by movement of the lever 32 and the link 82 which are operated by the cam 24 until the projection I6 on the arm 42 strikes the stop 18. The spring I6 is 5 compressed by further movement of the lever 32 which allows the lever 32 to complete its movement to the right without danger of breakage to the parts of the machine.

As the support 36 carrying a shoe I26 is moving toward the right to the position shown in Figs. 2 and 5, the sides of the upper adjacent to the toe end are engaged by rollers I28 mounted on the ends of arms I36 which are pivoted to the machine frame at I32 and I34.

Each arm is engages a cam track I52 in the cam 26.

provided at its other end with a segment I36 of a gear, the teeth of each segment being in engagement with the teeth of the other segment. The arms I30 are normally urged toward each other by a spring I38. Since the arms I36 aregeared together movement of one arm causes a movement of the other so that the shoe I26, regardless of its size, will be properly positioned beneath a prick punch or marking tool I46. When the marking tool I46 is moved downwardly by mechanism, which will presently be described, a spring I42 is stretched and causes the rollers I28 to press against the sides of the upper of the shoe, thus insuring that the shoe will contact with both rollers-to position the shoe laterally with respect to an operating tool I40. The rolls I26 are each mounted on pins I44 insuch a manner that the rolls are free to move vertically under the action of the operating instrumentalities contained in the machine head. A spring I46 encircles a reduced portion of each roll and causes the roll normally to be held in its upper position. The rolls I28 are spring mounted so that, although they are brought into engagement with the widest part of the toe of the shoe and close up against the welt, they still will have no tendency to tilt the shoe in case the sole and the welt are not beaten out perfectly flat upon one side of the shoe.

The mechanism for operating the marking tool is connected to the cam 26 by means of a system of links and levers. A bell crank lever I48 is pivoted to the machine frame at 34 and at its lower end is provided with a cam roll I56 which The other end of the bell crank lever I48 is connected by a link I54 to a lever I56 which is fulcrumed to the machine frame at I58. The lever I56 carries a cam roll I66 which contacts, at appropriate times, with a cam surface I62 on one arm of a bell crank lever I64. The other arm of the bell crank lever I64 is connected to one end of the spring I42, referred to above. The lever I66 has pivoted to its other end a bell crank lever I66 one arm of which is provided with a roll I68 which enters a recess in a sleeve or presser member I16. The sleeve I16 is mounted for sliding movement in a guideway I12 formed in the machine head 86. The sleeve I16 is normally urged upwardly by a spring I14 which has one end secured to a cap screw I16 in the lower end of the sleeve. The other end of the bell crank lever I66 has its end portion formed with a surface on the arm I11 (Fig. which engages a roll- I18 which is connected to a toggle I86. One link of the toggle I86 is secured to the upper end of the sleeve I16 and the other link of the toggle is fastened to the marking tool or prick punch I46. A spring I64 secured at one end to the toggle joint and at its other end to the machine frame nor mally tends to break the toggle.

When the link I54 is moved upwardly the lever I56 is rotated in a counterclockwise direction which causes the sleeve I16, through the bell crank lever I66, to be moved downwardly. The spring I64 is of such strength that the toggle I66 is not straightened until the sleeve I16 engages the shoe sole. The bell crank lever I66 then rotates about its axis and straightens the toggle against the tension of the spring I 84; At the same time the cam roll I66, which has been moved upwardly, engages the cam surface I62 on the lever I64 and stretches the spring I42 which causes the arms I36 of the bell crank lever to be moved toward the shoe thereby positioning the shoe properly with respect to the marking tool.

While the parts of the machinehave been described in detail, it may be well to summarize briefly the operation of the machine. The operator places a lasted shoe I26 on the last pin 46 5 on the support or jack 36, the operator pulls upwardly upon the latch I66. The latch pin 98 is lifted out of the notch 96 which permits the operator to move the support 36 until the pin 86 engages the forward end of the projection I26.

Movement of the support also moves the pin 86 away from the notch H2 which causes the arm 96 to drop downwardly. Movement of the link 82 toward the position shown in Fig. 3 causes the arm I22 to be pulled downwardly which moves the projection I26 out of the path of movement of the pin 86. The link 62 then drops downwardly so that the recess 84 engages the pin 66 and the support is moved into operating position. As the support moves into operating position, the hooked end of the arm 66 engages the pawl-like member I62 and rotates it about its axis. After the hooked end has passed out of engagement with the member I62, the member I62 is returned to the position shown in Fig. 3. As the support moves into operating position, the rolls I28 en- 30 gage the sides of the shoe upper adjacent to the toe end of the shoe to position the shoe laterally with respect to the tool I 46. The light spring I38 operates to resist the operation of the rolls I28 and the rolls, accordingly, are not forced against the upper with any great pressure.

During the portion of the cycle of operation that the support is being moved into operating position, the marking mechanism has been held in its upper position as shown in Fig. 2. When the support 36 has carried the shoe into the position shown in Figs. 2 and 5, the support remains at rest until the tool I46 has made a conical depression in the shoe sole. The sleeve I16 which operates as a presser member is carried downwardly by the movement of levers I56 and I66 until the lower end ofthe sleeve engages the outsole to press the outsole against the rolls I28. When the lever I56 is rotated, the cam roll I66, carried thereon, engages the cam surface I62 on the lever I64 and stretches the spring I42 to increase pressure of the rolls I28 against the upper to position positively the shoe and to hold the shoe in position until after the tool I46 has operated to mark the upper of the shoe sole. I84 which is connected to the toggle I86 is strong enough to prevent the lower arm of the lever I 66 from straightening the toggle until the sleeve I16 engages the shoe sole. After the toggle I86 has been straightened and the tool I46 has made a mark in the shoe sole, the sleeve I16 and the tool I46 are then returned to inoperative position and the mechanism for moving the support operates to return the support to its original position. Near the end of the return movement of the sup- 5 port 66 the hooked end of the arm 96 rides over a cam surface M6 on the member I62 thus raising the arm 66 which moves the recess 84 in the drag link 82 out of engagement with the pin 86. The support or jack 36 continues its movement under momentum imparted to it by the drag link until the latch pin 93 engages the notch 66 in the arm 96. The pin 66 on the toe support engages the notch I I2 on the arm 96and, together'with the latch pin 96, prevents movement of v The spring 55.

the support until the latch pin is raise-d. The shoe is then removed and another shoe placed on the support in readiness for another cycle of operation of the machine.
