15 Claims. (Cl. 12-124) This invention relates to toe lasting machines and is herein illustrated as embodied in a toe lasting machine of the type shown in an application for United States Letters Patent Serial No. 731,686, filed April 29, 1958, in the names of Joseph 0. Faneuf et al. It is to be understood, however, that in its broader aspects the invention is not limited to embodiment in a toe lasting machine of this particular type or to the exact mechanical construction herein shown.

In toe lasting machines of the above-mentioned type, the upper materials are wiped upwardly around and shaped to the toe end of a last and then are wiped inwardly over and pressed against the bottom face of an insole on the last by means of toe embracing wipers. Movement of the wipers heightwise relatively to the toe end of the shoe being lasted is effected in the aforementioned machine as a result of vertical movement of a wiper head by means of a foot treadle which is also used to urge the wipers forcibly against the overlasted margin of the upper materials, while advancing and closing movements of the wipers relatively to the wiper head are usually effected manually by means of a hand lever. In some instances, as in the machine illustrated in the mentioned application, power operated means are arranged to efiect the advancing and closing movements of the wipers under the control of the hand lever, while power operated means also under the selective control of the operator are provided for forcing the wipers against the overlasted upper materials to provide what is called the bedding down action.

When toe lasting machines of the above-mentioned type are used for the lasting of shoes with cement, it has been found that the application of heat and pressure, to the overlasted margin of the upper materials is desirable inasmuch as it tends to smooth down and iron the lasting margin as well as to speed up the setting of the cement used to secure the upper in lasted position. In fact, the use of heat and pressure in this way may even be beneficial, although the upper materials are held'in lasted position by metallic fastenings, such as tacks or staples, because of the smoothing and ironing action which is ob-' tained. In view of the diflicu-lty of handling heated wipers as well as the danger of marking or otherwise damaging the upper at the toe end of the shoe, several different types of auxiliary heated pressing members have been proposed for use in toe lasting machines for applying heat and pressure to the overlasted margin of the upper materials after the toe end of a shoe has been lasted and the lasting margin wiped inwardly over and pressed against the insole by means of cold lasting wipers. For example, it has been proposed to place a heated plate on the overlasted margin of the upper materials, after the lasting wipers have been elevated, at the conclusion of the lasting operation, and then to bring the wipers down on this plate to cause it to apply pressure to the upper materials; to provide separately operable heated pressing members arranged to be swung from a remote and inoperative position, inwardly over the toe end of a shoe after the Wipers have been retracted at the end of the lasting operation and then to cause the heated pressing members to exert ironing pressure thereon by means of a foot treadle; and also to arrange a heated presser or auxiliary wiping member so that it can be forcibly inserted between the wipers of a toe lasting machine and the overlasted upper materials at the toe end of the shoe. While each of these prior arrangements has some merit, none has proved to be entirely satisfactory in actual practice.

It is, therefore, a principal object of the present invention to provide in a toe lasting machine of the type here under consideration a novel and improved heated pressing member for applying heat and pressure to the overlasted margin of the upper materials at the toe'end of a shoe which is not only of relative simple and inexpensive mechanical construction but which is also easy to operate and especially reliable and efiective in use. With this purpose in view, the herein illustrated machine, which has a wiper head, toe wipers mounted on the head for advancing and closing movements relatively thereto from a retracted position, and wiper operating means including a hand lever for thus advancing and closing the wipers, and means for elfecting relative heightwise movement between the wipers and the toe end of a shoe being lasted, is provided with an auxiliary pressing member carried by the wiper head and mounted for movement relatively thereto in a direction extending lengthwise of the shoe being lasted, together with means under the control of the operator for selectively connecting the pressing member to the wiper operating means for movement by the hand lever. More particularly, and in the herein illustrated arrangement, fiuid pressure actuated means under the control of the hand lever are provided for operating the wiper-s and the auxiliary pressing member, which is heated in any suitable manner, is normally held in a retracted position against the action of means tending to move it in the directionof advance of the wipers, by means of a latch, and means are provided for connecting this heated pressing member to the wiper operating means when this member and the wiper operating means are in a predetermined relative position, together with means under the control of the operator, and preferably operable in response to elevation of the wiper head, for releasing the latch thus to cause the pressing member to be moved to said predetermined relative position and connected to the wiper operating means. Preferably, and as herein illustrated, novel means are interposed between the heated pressing member and the wipers, when they are in their retracted positions, for reflecting and absorbing heat radiated from the heated member thereby to prevent undue heating of the lasting wipers.

The above and other objects and features of the invention will appear in the following detailed description of the preferred embodiment thereof which is illustrated in the accompanying drawings and will be pointed out in the claims.

Referring to these drawings, and especially to Fig. 5, as has already been suggested, the novel features of this invention are shown as embodied in a toe lasting machine of the type disclosed in the above-identified application. Thus the herein illustrated machine has a wiper head, indicated generally by the reference character 20, this head being adjustably supported on an arm 22 which, in turn, is pivotally mounted, by means of a shaft 24, on the machine frame, an upper portion of which is shown and indicated by the reference character 26. Referring to Fig. 3, the wiper head includes a main portion 28, rotatably mounted on a carriage 30 which is adjustable along guideways formed on the arm 22, and a cover 32. Associated with the wiper head are two lasting

wipers

34, 34 each mounted on a wiper carrier, one of which is shown in Figs. 4 and 8 and identified by the reference character 36. Connected to these wiper carriers by means of

links

38, 38 is a crosshead 40 having formed integrally therewith a wiper operating rod 42. The wiper carriers are provided with cam grooves, not shown, which cooperate with rollers, see 44, 44 in Fig. 3, associated with the Wiper head and arranged to cause the wipers to be advanced and closed in response to movement of the wiper operating rod to the right from the position in which it is shown in Fig. 3 with the wipers 34 retracted and opened.

Such movements of the rod 42 are effected, in the herein illustrated machine, as in the machine of the above-mentioned application, by means of a hand lever 50 which is pivotally mounted, at its lower end, on a bracket 52 associated with a part of the machine frame 54, by means of a shaft 56 to which it is secured, this hand lever having at its upper end a handle 58, Fig. 5. Also secured to the shaft 56, on the opposite side of the bracket 52, is an arm 60 which is connected to one arm 62 of a bell-crank lever 64 having a second arm 66, by means of a pair of

links

68, 70 and a differential lever 72. The bell-crank lever 64 is pivotally mounted on the frame part 54 by means of a rockshaft 74. The difierential lever 72 is pivotally mounted on a pin 76 carried by the bifurcated end 78 of the stem of a bleed valve 80. As will be understood by reference to the abovementioned application, this bleed valve is normally held against its seat, not shown, by means of a locking lever 82, spring 84 and a piston in a cylinder 110. The arm 66 of the bell-crank lever 64 is operatively connected to a block 86, secured to the left-hand end of the wiper operating rod 42, by means of a link 88, bell-crank lever 90, having

arms

92 and 94, Fig. 5, and

links

96, 96, Fig. 1. With the valve 80 and pivot pin 76 thus immobilized, the

wipers

34, 34 may be manually advanced and closed, or retracted and opened, by means of the hand lever 50 with its operating handle 58 in a manner which will be readily understood.

In common with the machine of the above-mentioned application, the herein illustrated machine is also provided with power operated means, under the control of the hand lever 50, for advancing and closing the wipers. This power operated means includes a fluid pressure actuator 100 having an operating rod 102 which is connected to the arm 62 of the bell-crank lever 64. Also connected to this arm, by means of a yoke-like block 104, is the rod 106 of a fluid dashpot piston, not shown, contained within a casing 108. On the end of the handle 58 opposite to that which is shown in Fig. 5 there is a control member in the form of a push button (not shown) adapted to be moved axially of the handle against a yieldable resistance and, as will be understood by reference to the mentioned application, an initial movement of this push button renders the fluid pressure actuator 199 effective to apply, through its rod 102, a force on the arm 62 of the bell-crank lever 64 tending to swing the arm in a clockwise direction and thus, through the connections which have already been mentioned, to move the wiper ope-rating rod 42 to the right thereby advancing and closing the Wipers.

Such initial movement of the push button also has the effect of closing off a normally open by-pass, not shown, which is associated with the dashpot piston to afford communication between portions of the dashpot cylinder on the opposite sides of the piston, thus preventing movement of this piston and the other parts which are connected thereto, as explained above, and of exhausting fluid under pressure from the cylinder 110 thereby releasing the locking lever and the bleed valve to the action of the spring 84. Now, as the hand lever 50 is swung to the right, the bleed valve 80, which controls flow from one side of the dashpot piston to the other, will be opened to permit movement of the wiper rod through the action of the fluid actuator so that the wipers will be advanced and closed under power and to an extent determined by the extent of movement of the hand lever. In other words, and as is fully explained in the mentioned application, a servo or feedback action is obtained. To retract the wipers, the operator releases the push button, thereby discontinuing the power operaion of the wipers and then moves the hand lever to the left. Thus, the operator can advance and close the wipers manually during the upwipe operation and, when greater 6&0112 is needed for overwiping, he can quickly bring the power operated mechanism into action.

Connected to the outer end of the arm 22 is the upper end of a rod the lower end of which is connected to one arm of a lever 122, Figs. 5 and 6. The other end of this lever is connected by means ocf a link 124 to afoot treadle 126 which is pivotally supported on a lower portion 130 of the machine frame. By means of this foot treadle, the arm 22 may be swung about its pivotal mounting shaft 24 thereby to effect relative heightwise movement between the

wipers

34, 34 and the toe end of a shoe being lasted in the machine. Also connected to the lever 122, by means of a link 132, is the operating rod 134 of a fluid pressure actuator 136. As is explained in detail in the mentioned application, this actuator is adapted to be rendered operative, in response to an additional movement of the push button on the handle 58, so as to exert a force on the lever 122, rod 120 and arm 22 tending to swing the arm in a clockwise direction thereby to press the wipers firmly against the bottom of the toe end of the shoe being lasted.

For the purposes of this invention, the here-in illustrated machine is provided with a heated pressing member comprising a metallic block of the shape shown in Figs. 1 and 7 and formed integrally with a neck portion 152 which is secured to the right-hand end of a hollow operating rod 154, Figs. 3 and 8. This hollow rod is slidable within a bore 156 formed in the wiper operating rod 42, this bore being cut away to provide a clearance slot 158, Fig. 3, for a purpose which will presently appear. Secured to the left-hand end of the rod 154, between two threaded adjusting

collars

160, 162, is a block 164 to which there is pivotally mounted, by means of a trunnion pin 166, a latch lever 168 having an upturned right-hand end 170, Fig. 3. The member 150 is hollowed out at 172 to receive an electrical heating coil 174 (Fig. 7) which is connected to asuit able source of electrical energy, notshown, through a cable 176, Figs. 3, 7 and 8. A thin metal plate178 serves as a cover for the open-topped neck portion 152 and for the block 150. Extending upwardly from the top of the member 150, adjacent to its forward edge, is a narrow ridge of metal 180, Fig. 8.

When the

wipers

34, 34 are retracted, the block 86 on the wiper operating rod 42 engages the collar 162 and moves the heated member 150 to the retracted position in which it is shown in Fig. 3. At its left-hand end the latch lever 168 has an upwardly extending part 182 which is shaped to provide a beveled end 184 and a shoulder 186, Fig. 3, adapted to engage a locking lever 188, Fig. 2. This locking lever is pivotally mounted, by means of a pin 190 on a bracket 192 which issupported on the carriage 30. This lever has a downwardly extending end 194 which is connected, by means of a link 196, to the armature 197 of a solenoid 198. When this solenoid is energized, the locking lever 188 will be swung in a counterclockwise direction, against the resistance of a coil spring 200, which normally holds the lever 188 in the position shown in Fig. l and as determined by a stop surface 199 on the bracket 192, thereby releasing the end 182 of the lever 168. A coil spring 202, stretched between a pin 204 on thecarriage 30 and an eye 206 secured to the lever 168 tends to swing that lever in a counterclockwise direction and also to move the block 164 and rod 154 to the right, Fig 3. -Such swinging movement of the lever 168 is, however, prevented when the parts are in the positions shown in Fig. 3 by means of a bar 208, carried by the bracket. 192 and engaging the lower side of the beveled end 184 on the part 182 of this lever. Movement of the rod 154 by the spring 202 is, of course, prevented by engagement of the collar 162 with the block 86.

The solenoid 198 is normally deenergized'so that the locking lever 188 remains in the position shown in (Fig. 2 when the rod 42 is moved to the right either manually or by the power operated means, to advance and close the

wipers

34, 34, the slot 158 in the lower part of the operating rod 42 now receiving the neck portion 152 asso ciated with the heated pressing member 150 which remains in the retracted position in which it is shown in Fig. 3. When the solenoid 198, is energizedpthe locking lever 188, Fig. 2, is swung in a counterclockwise direction, thus releasing the lever 168 and the block 164 to the action of the spring 202. First, this spring swings the lever 168 in a counterclockwise direction through a small angle and until its upturned end 170 engages the flat lower surface on the block 86 and thenthe block 164, rod 154 and heated pressing member 150 are moved to the right until the collar 162 engages the end of the block 86 thereby establishing a predetermined relation between the heated pressing plate and the wiper operat: ing mechanism in which the upturned end 170 of the latching lever passes beyond the right-hand end of the block 86. The lever 168 is now swung further in a counterclockwise direction to cause its upturned end 170 to enter a'notch 210 in the wiper operating rod, thus connecting the heated pressing plate thereto for movement with this rod as the wipers are. advanced and closed, either manually or by power, or retiractedmanually, as explained above.

For thus energizing the solenoid 198 any convenient arrangement may be provided. However, in the herein illustrated machine, this is accomplished as a result of the elevation of the wiper head 20 by upward swinging of the arm 22 by the treadle 126. Thus there is mounted on abracket 220, associated with the fluid pressure actuator 136, a microswitch 222 having an operating plunger 224 and connected in the electrical line leading from a source of electrical energy, not shown, to the solenoid 198. Mounted on the operating rod 134 of the fluid pressure actuator 136 is a bracket '226carrying an adjustable abutment screw 228. As will be apparent, when the treadle 126 is actuated to elevate the wiper head 20, the switch 222 will be closed and the solenoid 198 energized. When the head is lowered, after the heated pressing plate has been projected to operative position and connected to the wiper operating rod 42, in the manner just explained, the switch 222 will be opened and the solenoid 198 deenergized, thus permitting the locking lever 188 to be returned to the operation shown in Fig. 2. Accordingly, when the

wipers

34, 34 are fully retracted and the heated pressing member 150, operating rod 154 and block 164 have returned to the positions shown in Fig. 3, the lower side of the beveled end 184 of the upturned portion 182 of the latching lever 168 will engage the rod 208 and be carnmed upwardly while the upper side of this beveled end will cam the locking lever upwardly, by engagement with a camming surface 230 thereon, Fig. 3, thereby permitting the parts to reassume the locked positions shown in Fig. 3. As will be apparent, even though the solenoid 198 may become energized as a result of elevationof the wiper head while the wipers are fully retracted, no movement of the latching lever 168 or of the heated pressing member could occur because of the engagement of the beveled end 184 of the lever 168 with the rod 208 and the engagement of the collar 162 with the block 86.

In order to render the heated pressing member 150 practically elfective is is necessary that it be heated to a relatively high temperature, e.g., 400 F. It is, however, extremely undesirable that the

lasting wipers

34, 34 become anywhere near as warm. To prevent this from happening, there is interposed between the heated pressing member and the wipers when they are in their retracted positions, Fig. 3, means for absorbing heat and for reflecting heat away from the wipers. This means comprises a housing member 300 shaped as shown in Figs. 1, 4 and 8, and secured to the wiper carrier body portion 28 by means of bolts 302 and spacer blocks 304. On its lower side, this housing member, which is preferably formed of aluminum, is provided with a bright surface for deflecting heat from the heated presser member 150 downwardly and away from the wipers. Also, as can be seen in Fig. 4, the member 300 is formed with two sets of reverse folds 306, 308, 306, 308 through which air may circulate and thus dissipate to the atmosphere heat absorbed by the member 300.

Referring to Fig. 8, the heated pressing member 150 is shown in its projected and operative position beneath the advanced and

closed wipers

34, 34. It is also shown in operative engagement with the overlasted margin M of the upper materials U of a shoe S being lasted in the machine. It will be observed that the narrow ridge of metal 180 which adjoins the leading edge of the heated pressing member, is spaced quite close to the lower face of the Wipers. Accordingly, when the heated pressing member is urged forcibly down against the overlasted margin of the upper materials of the shoe, after yielding in an upward direction slightly, as permitted by a slight looseness of the parts and the flexibility of the neck portion 152, it will be supported firmly by the engagement of the ridge 180 with the wipers. However, this metal-tometal contact is of such a slight extent in area that little, if any, heat is thus transmitted from'the heated pressing member to the wipers.

The operation of the herein illustrated machine and of the novel and improved heated pressing member should be apparent from the above description. It will, however, be noted that the heated pressing member, while normally held in an out-of-the-way location, is immediately available for use and can quickly be brought into operative position and connected to the wiper operating rod in response to an elevation of the wipers after the overwiping operation has been completed. When thus connected to the wiper operating rod this heated pressing member may not only be used for applying direct pressure to the overlasted margin of the upper materials but it also may be moved in directions extending lengthwise of the shoe, either manually or by the power operated means, to provide a definite ironing action which tends to augment the overwiping action of the wipers. Because of the retention of the heated pressing member in a retracted position and the provision of the heat reflecting and absorbing member, interposed between the heated pressing member and the retracted wipers, this heated pressing member may be maintained at a much higher temperature than otherwise would be possible and its effectiveness is correspondingly increased. For example, the member 150 can be heated to a temperature of over 400 F. while the temperature of the wipe-

rs

34, 34 does not rise much above 120 F. Also, with the arrangement herein illustrated, accidental projection of the heated pressing member into direct engagement with the upper materials at the toe end of the shoe being lasted, which might result in burning or in otherwise marring the upper in a location which would be visible in the finished shoe, is entirely avoided.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
