This invention relates to machines for use in attaching soles to shoes by cement, either preliminarily as in sole laying or permanently as in the manufacture of compo shoes, and is illustrated herein as embodied in a machine particularly intended for use in cement attaching soles in the manufacture of compo shoes.

Machines for use in cement attaching soles to shoes are disclosed in my copending application for Letters Patent of the United States, Serial No. 352,278, led April 3, 1929, and in the United States Letters Patent No. 1,897,105, granted February 14, 1933, on the application of Milton H. Ballard. The machine disclosed in the patent, which embodies many of the features of the invention of the above-mentioned application, has gone into extensive commercial use and has given general satisfaction. It is an object of the present invention to provide a still further improved machine for use in cement attaching soles to shoes.

The majority of the shoes manufactured by the compo process are Womens dress shoes of light weight and dainty appearance. The shank porv tions of the soles of such shoes are usually reduced substantially to a feather edge and are convex. The edges of the forepart are also somewhat reduced and should hug the upper closely so that, with the close edge trimming which is practiced in the manufacture ci such shoes, the edge of the sole at the shank will be practically invisible and at the orepart will be quite inconspicnous when the shoes are worn.

Sole attaching machines of the type disclosed in kthe application and patent referred to above are provided each With a duid-filled pad member arranged to receive a properly cemented and prepared sole` and shoe and, in cti-operation With a suitable abutment or abutments, to apply sole attaching pressure. In order that the same pad member may be used with satisfaction on diiferent sizes and styles of shoes its top or sole engaging surface is substantially ila't transversely, the sole attaching pressure being relied upon to distort the sole receiving surface of the pad so that it will press substantially uniformly over the whole of the surface of the sole. Since, as pointed out above, the shank portion of the sole may be convex transversely to a substantial extent it follows that when the sole is first placed on the surface of the pad member the edges of the shank portion of the sole may be spaced a substantial distance from the surface oi the pad. lt is an object or the invention to provide means by which the preliminary pressure, which precedes `the llal shoes.

The machines of the application and patent referred to above are provided With fingers or feelers arranged to engage and be positioned by the edge of the sole and to control additional fingers by which the shoe is positioned relatively to the sole on the pad member. The rubber soleengaging Walls of the pad members exhibit a tendency to become slightly concave after they have been used for a time, so that it is possible for an operator to place a sole on the pad in such a manner that it will escape from or not be properly engaged by the sole engaging ngers by'reason of the sole being positioned in this depression oi" the Wall of the pad. It is another object of the present invention to obvate all possibility oi' this diiliculty and this is accomplished, as illustrated herein, by slightly bulging the sole-receiving wall of the pad at the time that the fingers are brought into operation.

The depth which a shoe needs to be sunk into a pad member in order to secure proper contact of the pad member with the sole of the shoe varies considerably with different sizes and styles of lt is, therefore, a further object of the present invention to provide means by which the preliminary pressure will be uniform and unvarying regardless of the extent to which the shoe is sunk into the pad.

While the invention is illustrated herein as embodied in a machine developed for use in cementY attaching soles to shoes it should be noted that in various of its aspects it is not limited'to embodiment in such a machine. It could, for example, be embodied in a machine for use in sole laying or direct pressure leveling as performed in the manufacture of shoes the soles of which are permanently attached by stitching.

With the above and other objects and features in View the invention will now be described with respect to the accompanying drawings and' showing the parts with the machine idle or at rest, Fig. 4 showing the parts during the application of the preliminary pressure, Fig. 5 showing the partsv at the conclusion of the application of the preliminary pressure, and Fig. 6 showing the parts while the final pressure is being applied;

Fig. 7 is a detailed view of a toggle mechanism which serves to connect the two weights by which the pressure is applied; and

Figs. 8 and 9 are fragmentary views showing details of a safety device by which premature application of the final pressure is prevented, Fig. 8 showing the parts in position to permit and Fig. 9 in position to prevent application of the nnal pressure.

The present invention is illustrated herein as embodied in a machine of the character disclosed in the Ballard Patent No. 1,897,105 referred to above. Many of the details of the machine are of no importance as far as the present invention is concerned and for such portions of the machine as it has not been found necessary to describe or illustrate herein reference may be had to that patent.

The illustrated machine is provided with a table 20 supported by legs 22 and arranged to receive a pad box 24 (as best shown in Figs. 1 and 2) by which a shoe 26 and a sole 28 (Fig. 5) may be held clamped forcibly together while cement by which the sole is to be attached to the shoe sets. The machine is provided with means for positioning the toe end of the shoe relatively to the sole before the clamping pressure is applied, as indicated generally by the reference character 30 in Fig. 1, which means, preferably and as illustrated, is of the character described in my copending application Serial No. 352,278. Means is also provided for positioning the heel end of the shoe relatively to the sole as indicated generally by the reference character 40. Preferably and as illustrated the heel-end positioning means is of the type disclosed in my said application, and more specically of the character disclosed in my copending application for Letters Patent of the United States Serial No. 414,516, filed December 16, 1929 to which reference 'may be made for a detailed disclosure of that mechanism. Briefly, the toe end positioning mechanism 30 comprises sole engaging ngers or feelers 31 and shoe engaging fingers 32 mounted on a carriage 33 by which they are moved from inoperative to operative position through the medium of a weight 34 connected with the carriage 33 by a cable 35 upon the tripping of a foot treadle 50 to which the carriage 33 is connected by means of a cable 36 and a rock arm 37 carried by a rock shaft 52 by which the treadle 50 is carried, as best shown in Fig. 2. The heel end positioning mechanism 40 includes sole engaging feelers or fingers 41 and shoe engaging fingers 42 mounted on a carriage 43 connected with a weight 44 by a cable 45, the carriage 43 being connected to a portion of the mechanism of treadle 50 by a cable 46 so that the tripping of the treadle 50 brings the heel end positioning fingers 41 and 42 into operative position simultaneously with the similar movement of the toe end positioning fingers 31 and 32. While the details of the treadle mechanism are illustrated to a large extent, particulai-ly in Figs. 1 and 2, it will be unnecessary to describe them herein since they are identical with the corresponding mechanism shown and described in the Ballard Patent No 1,897,105,

to which reference may be had for a more detailed description. For an understanding of the present invention it is only necessary in this connection to remember that when the treadle 50 is tripped it moves generally upwardly, that is, in a clockwise direction as shown in Fig. 2, whereby the positioning mechanisms 30 and 40 are brought into operation.

The pad box 24 comprises a boxlike structure 60, preferably an aluminum casting, the bottom o which consists of a doorlike plate member 62 pivoted at 64 to the member 60. A rubber pad or bladder 66 is contained in the boxlike member 60. A plate 68, secured to the casting 60, overlies the marginal portion of the bladder 66 and preve-nts its upward movement when the plate 62 is forced upwardly to apply sole attaching pressure. In order to prevent upward movement of the shoe when the soie attaching pressure is applied, the casting carries a pair of yokes 70 and 72 positioned over the forepart and the heel portion receiving areas of the bladder 66. As illustrated the yoke 70 carries an abutment member 74 arranged to contact with the forepart of the shoe while the yoke 72, which is pivoted for swinging movement into and out of operative position, carries an abutment 76, best shown in Fig. 5, arranged to receive the cone of the last. These abutments may be moved downwardly to apply preliminary pressure to the shoe and the sole on the pad box 24 by mechanism illustrated generally at in Figs. 1 and 2 and operated by the depression of a treadle 82, all as fully described in said Ballard Patent No. 1,897,105.

The mechanism so far described forms per se no part of the present invention and it has, therefore, been described as briefly as is thought to be consistent with a clear understanding of its relation to the novel mechanism which will now be described.

Referring now particularly to Figs. 2, 3, 4, 5, and 6 it will be seen that a plunger 90 is mounted for vertical sliding movement in a bore formed in the table 20, the upper end of the plunger being spaced slightly from the doorlike member 62 of the pad box (as shown in Fig. 3) when the machine is in its idle inoperative position. The lower end of the plunger engages the forward end of a lever 92 fulcrumed at 94 to the frame of the machine. The rear end of the lever 92 is pivoted at 96 to a depending link 98 the lower end of which is pivoted at 100 to a rock arm 102 secured to a rock shaft 104 having suitable bearings in the frame of the machine and carrying also a longer forwardly extending rock arm 106 from which depends toggle mechanism 108 shown in detail in Fig. 7. A weight 110, which is utilized to supply the preliminary pressure, is

also pivotally connected to the forward end of the arm 106 while a heavier weight 112 which, together with the weight 110, applies the final pressure is carried by links 115, 117 (Figs. 2 and 4), secured at 113 both to the lower end of the toggle 108 and to the forwardly projecting end i of a bell crank lever 114 fulerumed at 116 on the frame of the machine and carrying also a shoe 118 engaging an eccentric 120 fast on a shaft 122. In a machine of the character illustrated,

and having the various lever arms of about the sure of about 15 to 20 pounds to the square inch 1.,,

and a iinal pressure of about 60 to 80 pounds to the square inch on womens shoes. Y l

The toggle 108 comprises upper and lower links 130 and 132 respectively, (Figs. 3 to 7) the former being carried by a stub shaft 134 projecting laterally from the forward end of the lever 106. Secured to the upper end of the lower toggle link 132 is a stub shaft 136 to which the lower end of the upper link 130 is pivoted while the lower end of the link 132 receives the stub shaft 113. rhus it will be seen that the toggle 108 forms a connection between the two weights 110 and 112 which when straightened permits one weight to be carried by the other but which permits the two weights to be supported independently of each other when the toggle is broken. At times during the operation of the machine the weight 110 is supported from the weight 112 by the straightened toggle as shown in Fig. 3.

The toggle breaks to the left as shown in Figs. 3, 4, 5, 6 and 7. Accordingly, the lower toggle member 132 is provided with a projecting portion 138 engaging a surface 140 of the upper toggle member 130 as best shown in Fig. 7 and limiting the movement of the stub shaft 136 to the right as the toggle is straightened, to a position slightly beyond the dead center. To prevent inadvertent displacement of the dead center to the left of the line joining the axes of the stub shafts 113 and 134, while the weight 110 is supported by the straightened toggle from the weight 112, a spring pressed plunger 142 is housed in the upper toggle member 130 and has a lower V-shaped end 144 adapted for engagement with an inclined surface 146 formed on the lower toggle member 132. A pin 148 carried by the plunger 142 is located in a slot 150 formed in the upper toggle member 130 thereby preventing rotation of the plunger 142 and holding it at all times in such position that one of the surfaces of its V-shaped end 144 is in position to engage with the surface 146 of the lower toggle member 132 when the toggle is straightened. Thus it will be seen that in order to break the toggle it is necessary vto exert suicient force to cam the plunger 142 upwardly a short distance against the compression of its spring.

A lever 160, having a U-shaped portion straddling the lever 92, is fulcrumed on the shaft 94 for movement relatively thereto. One arm of the lever 160 is pivoted at 162 to a long downwardly and rearwardly extending link 164. the lower end of which is pivoted at 166 to a rock arm 168 fast upon the shaft 52. the construction being such that when the treadle 50 is tripped and moves upwardly in a clockwise direction as viewed in Fig. 2, the link 164 will move downwardly, rocking 'the lever 160 in a clockwise direction. This clockwise movement of the lever 160 is'eiective to break the toggle 108, the lever 160 being provided for that vpurpose with an arm 170 carrying a pin 172 which, when the parts are positioned as shown in Fig. 3 with the toggle straightened, is substantially in engagement with the lower toggle link 132 adjacent to the pin 136. It will be apparent, therefore, that clockwise movement of the levei` 160 will cause the pin 172 to push the toggle past the dead center, to the left as shown in Fig. 3, breaking the toggle as shown in Fig. 4. This takes place as the sole engaging and shoe positioning fingers 31, 32, 41, 42 are moved into operative relation to a sole on the pad b oX and while the heavy weight 112 is supported by the bell crank lever 114, the shoe 118, and the eccentric 120, and causes the smaller weight 110 to move downwardly thereby rocking the lever 106, the rock shaft 104 and the lever 102 in a counter-clockwise positionas viewed in Figs. 3 and 4, and rocking the lever 92 in a clockwise direction and causing its forward end to thrust the plunger 90 upwardly into contact with the plate 62 of the pad box, as shown in Fig. 4. This elevates the plate 62, bulging the upper surface of the bladder slightly so that the edges of the sole which the operator `has previously placed on the bladder can by no possibility be below any portion of the surface of the bladder and therefore in a position where it can not be engaged properly by the sole engaging feelers 31, 41.

The operator next places the shoe 26 on the soie 28 and swings the yoke 72 into vertical position so that the abutment 76 will be' above the cone of the last. At this time, of course, the abutment 74 wili be above the forepart of the shoe. The operator then depresses the treadle 82, forcing the abutments downwardly and sinking the shoe and sole into the top of the bladder far enough to cause the bladder to bulge upwardly somewhat around the entire periphery of the shoe, as shown in Fig. 5. As the shoe is sunk into the bladder the pivoted plate 62 will move downwardly, forcing the plunger 90 downwardly and lifting the weight 110. From this it follows that the preliminary pressure is maintained uniform regardless of the depth to which the shoe is sunk into the bladder, since the preliminary pressure is determined definitely by the mass of the weight liO and the lever ratios, which are unvariable. This lifting of the weight 110 moves the toggle toward, but normally not entirely to, its straightcned position, Fig. 5 showing a. normal position at the completion of the applying of the preliminary pressure. After inspecting the shoe and sole to see that they are properly located relatively to each other, the operator depresses a hand lever 176, shown in Figs. 1 and 2, and more fully described in said Ballard Patent No. 1,897,105, causing the shaft 122 and the eccentric 120 to be moved through a single rotation and then to come to rest. As the eccentric rotates toward its middle position,`which is shown in Fig.y 6, it moves from the shoe 118 to release the lever 114 so that the weight; 112 can move downwardly, straightening the toggle 108, which then serves as a tension member to suspend the weight 112 from the stub shaft 134. Thus the weight 112 is in eiiect supported fronithe weight 110 and the mass of the weight 112 is added tothe mass of the weight 110, the two together, through Athe lever mechanism, forcing the plunger 90 and the pivoted member 62 upwardly and thereby distorting the lower wall of the bladder 60 and supplying the final sole attaching pressure. The pivoted member 6 2 is automatically latched in the uppermost-position lto which it is moved by mechanism indicated generally at 178 in Figs. 1

vand 2, which mechanismv is fully illustrated and disclosed in said Ballard Fatent No. 1,897,105, so that the final pressure is maintained when the shaft'l22 and the eccentric 120 complete their revolution and thereby lift the weight 112 to the position shown in Fig. 3. Since the toggle 108 has been straightened by the lowering of the weight 112, the lifting of the weight 112 also lifts the weight 110, .the spring plunger 142, by reason of the engagement of one of the faces of its V- shaped'end surface with Ythe surface 146 of the toggle member 132, urging the toggle slightly past its dead center (as shown in Fig. 7) so that it can be relied upon as a compression member.

'I'his leaves the mechanism for operating the plunger 90 in the position in which it is shown in Fig. 3 so that the pad box 24 may be removed and another placed in the machine.

The safety mechanism, best shown in Figs. 1, 8, and 9, is provided to prevent premature tripping of the lever 176. This mechanism comprises a bent lever 200 pivoted at 202 to the frame of the machine and provided with an adjustable stop 204 arranged for engagement with the left hand side of the lever 176, and a second adjustable stop 206 arranged for movement into and out of position below the adjustable stop 208 carried by the lever 176. It will be seen that when these parts are in the positions shown in Fig. 9 the lever 176 can not be depressed sufficiently to throw into operation the mechanism for applying the final pressure. On the other hand, when the lever 200 is swung to the left, to the position shown in Fig. 8, the lever 176 can be depressed. The lever 200 is moved from the position shown in Fig. 9 to that shown in Fig. 8 by a finger 210 secured to the weight 110. When the treadle mechanism 50 is tripped to bring the sole and shoe engaging fingers 31, 32, 41, 42 into position the weight 110 moves downwardly sufficiently to bring the end 212 of the finger 210 beneath the inclined surface 214 of the lever 200 as shown in Fig. 9, thus causing the stop 206 to prevent depression of the lever 176, and it is not until the weight 110 has been lifted by the application of the preliminary pressure that the end 212 of the finger 210 rocks the lever 200 in a clockwise direction, as shown in Fig. 8, so that the lever 176 can be depressed to throw the final pressure applying mechanism into operation.
