and tacks are driven to secure the materials to the insole. Subsequently the parts are returned to their starting positions and theupper and insole unit removed from the form 12. For a more complete understanding of these operations and of the construction of the machine as thus far described reference may be made to the Letters Patent mentioned. I v 1 Loosely pivoted for swinging movement about the same shaft 18 upon which the form earrier 16 is mounted is a bracket 2 l which has fixed thereto a rod 26 extending upwardly into proximity to the top of the form carrier 16 and having at its upper end a head 28 forked to embrace. av bracket 30 which projects forwardly anddownwardly from the top '6 of the machine frame. This bracket hasfa curved lower face and acts as a guide when the rod 26 is swung rearwardly, as will be hereinafter more fully explained. The bracket 30 has at its front end a downwardly projecting portion in which is adjustably mounted a stop screw 82 in position to engage the head 28 and thereby limit forward swinging movement of the rod 26. Mounted upon the-rod 26 isa sleeve 24 which may slide l p-- wardly and downwardly on the red but is held from turning 'novement by means of a key (not shown). The sleeve 34 is normally pressed upwardlyagainst the head .28 by means of a spring 36 which is located. between a collar 38 fast on the rod 26 and'the top of a recess in the sleevein which the spring is located. Atreadle 40 which is pivoted upon the shaft 8 is connected by a link l2 to a bracket 44; on the sleeve 34 to movethe sleeve downwardly against the resistance of the spring 36 for clamping the insole on the bottom of the form 12,- as more fully hereinafter explained. g

The sleeve 34 is held in any position to which it is lowered by the treadle 40 by means of a clutch member 46 which is fast on a pivot pin 48 mounted to turn in the sleeve 34, the clutch member being arranged to engage a wear plate '50 which is fast. on the rod 26. Also fixed to the pin48 is a lever 52 which is pressed downwardly by a spring plunger 54 in thesleeve 3d, the clutch member 46 thus 7 being normally held by the spring plunger 54; in positiontolock the sleeve 34 against up matically at a predetermined time intheeycle f of the machine, a cam-controlled lever 58 is provided which by upward movement contacts with and raises the rear end of the lever 52. l

Mounted in the bracket 44 is a pivot pin 60 which carries an arm 62 that is norn'ially swung laterally away from the form 12 by means of a sprlng plunger 64 engaging the bracket 44-, such. swinging movement of the arm being limited by a slotted link 66 which is pivoted on the sleeve 84. tried by the arm 62 is arranged to engage,

when the arm is swung toward the form 12 with a grooved bracket 70 which is fast on the sleeve 34 to assist in guiding the arm and A tongue 68 carcarrier 16 about the axis of the shaft 18 when the form carrier is swung rcarwardly to carry the work into the heel band. The arm 62 is also provided with a slotiti to receive the bracket 30' when the arm is swung rear- Nvardly with the form carrier 16, thus insur ing that the arm will not swing laterally of the form to its idle position until the sleeve e the arm from the short 'A spring 90 which bears on the upper end of the rod 86 affords provisionfor yieldwhen the member 88 is carried downwardly into engagement withan insole, and this spring, by bearing upon the head 78, has a tendency and the rod 26 have been swung forward ly, even though the sleeve 34 should be moved to swing themember'84 about its pivot 82 to a limit determined by a stop screw 92. The member 88 may thus tip lengthwise of the form as it is pressed down on the insole until itbecomes seated evenly upon the insole.

Mounted upon the machine frame at 94: is a cam-operated bell-crank lever 96 provided with a rell98 which at a predetermined time in the cycle of the machine is swung forward.- ly to engage a face 100 upon the sleeve 3 1, this face being then in the position indicated by dotted lines in Fig. 2. By this means the sleeve 31 and the rod 26 are swung forwardly about the shaft 18 until they are past the vertical, and thereafter the parts are swung farther forwardly by gravity until the head 28 engages the stop screw 32.

The means provided for pulling the upper i'forwardly about the form 12 and for engaging the toe end of the insole to assist in positionii'ig it relatively to the form and the up per are illustrated particularly in Fig. On. the front upper portion of the form carrier 16 is a boss 102 (Figs. 1 and 3) which is shaped to provide a vertical guideway 10 1 for a bracket 106 that has mounted in it a pinion 10S arranged to engage rack teeth 110 formed on the boss 102. The pinion 108 is rotated by a hand wheel 112 to raise or lower the bracket 106, and suitable means (not shown) is provided for locking the hand wheel so as to hold the bracket in adjusted position. At its upper end the bracket 106 is provided with a head 114: in which. there is mounted for movement at right angles to the guideway 104 a gripper carrier 116 provided with rack teeth 118 engaged by a pinion 120 in the head 11 1. This pinion is turned by a hand wheel 122 to adjust the gripper carrier 116 lengthwise of the shoe upper, and sitiit-able means (not shown) is provided for holding the hand wheel in adjusted position.

The front end of the ripper carrier 110 is in the shape of a forked head which is embraced by the forked lower end of a member 121- pi'votallv mounted on a spindle 120 in the forked head. Pivoted in the lower ends of the forks of the member 124. is a pin 128 into which is threaded a screw 130 which passes through a recessed lug 132 depending from the carrier 116. A spring 1351. surrounding the screw 180 is located within the recess of the lug 132 and presses the pin 12S forwmrdly. The upper end of the member 121 has a projection 136 which carries apad 138 of yielding material and is adajjited to serve as one of a pair of gripper jaws. Pivotally mounted at 1 10 on another projection of the member 121 is a curved arm 112 which serves as the other gripper jaw. One end of the arm 112 is connected by a link 1 11 to an arm 14 (5 of a bell-crank lever which pivotah ly mounted. on the spindle 126. The other arm 118 of the bell-crank lever is connected by means of a rod 150 to a trcadle (not shown), so that by depression of the treadle the gripper jaw lei-2 first swung into gripping relation to the jaw 136 and then by continued movement of the treadle the gripper jaws are swung about the spindle 126 to pull the upper forwardly. A spring 152 con nected at its opposite ends to the member 124.

and to the lever arm 148 serves to hold the gripper jaw 142 initially in an idle position widely SGIMHELtOd from the jaw130 so that the molded toe portion of the upper may be readily inserted between the jaws. For hoht ing the gripper jaws in upper-tensioning position the lever arm 1% has pivotally mounted thereon a spring-held pawl liiel which is arrangedv to engage ratchetteeth 156 formed on a forward extension of the carrier 11.0. The pawl is provided with a tail portion so that the operator can release it when desired, the parts then returning to inoperative position under the action of the springs 13% and 152.

The gripper jaws 15-36 and 1 12 are large enough to engage the upper 0v r a substan tial area rearwardly of the tip line and are arranged to engage the upper, for the most part at least, at the rear of the previously molded. toe portion, the jaws being also so shaped as to clear the portion of the upper which is located in front of their gri tij'iing faces. There is thus no danger of distorting the previously molded toe portion of the upper in pulling the upper forwardly about the form. It will further be seen that the tension is appliedv to the upper in a location which includes a considerable area of the upper midway between its opposite side portions in front of the lacing slit, so that-the gripper is Very eil'ective in drawing the upper 'f()1.'W2t1'(lly to seat it snugly against the back and the sides of the form 12.

After the upper has been thus tensioned about the form '12, the heel end of an insole is placed upon the form and is engaged with the upstanding margin of the tensioned upper materials which thus provide an effective abutment against which to press the edge of the insole to locate in proper position on the form. Further to assist in posiuoning the insole and in holding it .in proper position, there is mounted upon the curved gripper jaw 142 an insole-positioning and holding device conipriiaiing an upwardly projecting narrow finger 158 connected by a screw 160 to an oilset 111 on a bracket 102 which fast on the jaw H2. The linger 158 is provided. with a recess or notch 161 to receive the toe end of the insole, and it is intended that, to as.' t in determining the proper lateral position of the forepart of the insole, the middle point of the toe end of the insole will be located in engagement with the lii'iger 158 which thus serves as a sight gage. The

its forepart when it is positioned by the finger and is thus held under longitudinal compression. In this manner the heel end of the insole is pressed snugly against the upstanding margin of the upper and its toe end is held in frictional engagement with the finger 158 to prevent its displacement until the clamping member 88 is moved into clamping position.

In the operation of having its toe end molded is placed about the form 12 when the form is in its forwardly swung position and is so adjusted by the operator as to position the back seam in proper relation to the form and to cause the proper amount of the upper materials to pro ject above the bottom face of the form; By

depression of the treadle rod 150 the forepart of the upper is then gripped by the jaws 136 and142 and theupper is tensioned about the form, the gripper being locked in tensioning position by the pawl 154. The operator is then free to remove his hands from the up per, which is held in position about the form by the gripper, and he next places the in: sole upon the form and in proper relation to the insole positioning and holding member 158 in the manner hereinbefore described. The arm 62 is then swung toward the form so as toposition theclamp member 88-above the form, and the treadle 40 is depressed to bring the clamp member into clamping engagement with the insole. Upon the starting of the ,machine by depression of the treadle 10 the form carrier 16 and its uppertensioning means, together with the arm 62 and the insole-clamping member 88, are swungrearwardly as'a unit to carry the form 12 into the heel band which is then closed to shape and clamp the upper. about the form. Thereafter the wipers 22 are oper-' ated to wipe the margin of the upper in- Wardly over the heel end of the insole and the tackingmechanism (not shown) is moved into positionand is operated to. secure the ,margin of the upper to the insole, as more fully described inthe before -mentionedLetters Patent. Between the overwiping and the tacking operations the lever 58 is operated to release the sleeve 34 from the rod 26, and

the sleeve is then movedupwardly by its spring 36 to withdraw the clamp member 88 frointhe insole and to unlocltthe arm 62 from the rod 7-1 on the form carrier 16. The

' roll 98 thenacts to swing the sleeve 34 for- I wardly, and at the end of the forward movement of the sleeve the spring plunger 64C acts to swing the arm 62 laterally to its. starting position. In this manner the insole-clamping means is withdrawn from the form so as chine to starting positions after the tacking operation the form carrier 16 is swung forthe machine, an upper of the tip line.

release the upper, so that the upper and 1nsole unit may beremovedfrom the form. f

Various features of the means herein shown for clamping the insole upon the form are not claimed herein, since they are the invention'of William C. Baxter and are claimed in a co-pending application Serial No. 19,347, filed on March 30, 1925.
