MACHINE FOR USE IN THE K ANUFACTURE OF SHOES.
Application filed July 25,
This invention relates to the manufacture of shoes, and is herein exemplified in its application to the molding of the toe portion of upper materials to give them substantially the shape which they are to have in the finished shoe. It will be recognized, however, that in many of its important aspects the invention is not limited to the shaping of the toe portion of upper materials, nor to the shaping of uppers as distinct from other shoe parts, and that in still other aspects the 1nvention is not limited to molding in the treatment of uppers or other shoe materials.
Among its objects the invention has in view important economies in shoe manufacture and uniform excellence in the quality of the product. Even in the present comparatively advanced stage of development of the shoemaking art, many operations depend for success upon the exercise of great skill and judgment by the workmen, thus entailing a high labor cost, and this is conspicuously true of the shaping of the upper materials. In shaping the toes of uppers, for example, much care and skill are needed, not only to conform the upper closely to the characteristically irregular curvature of the last or other shoe form, but also to gather and shape the marginal portion of the material smoothly and uniformly as required for the appearance of the shoe and for successful results in subsequent manufacturing operations, and to establish correctly and in accordance with a predetermined standard the lines of the upper characteristic of the given style of shoe. Even with the exercise of the greatest care and skill obtainable at a high labor cost, the difficult and critical operations involved in upper shaping often fall short of that degree of accuracy and uniformity which is recognized as essential for the best shoemaking.
In View of the above mentioned and other conditions and with the general object above set forth, the present invention, in its illustrative embodiment, provides a novel machine organization designed for standardization in the shaping of upper materials. A very important feature of the organization, which contributes directly to uniformity of the product and to the elimination of the need for a high degree of skill on the part of the workman, consists in the combination of 1921. Serial No. 487,384
means for operating upon the material and means for jigging the material to position it relativel to the means which operates upon it. T at is, as herein exemplified, there is provided means for insurin by engagement with positioning surfaces ormed on the upper in predetermined relation to a characteristic thereof the proper position of the upper in relation to the upper-shaping means in respect to such movement as might affect the accuracy of the shape imparted to the upper by said means. The machine herein shown comprises means for utilizing jig holes formed in the marginal portion of the toe of the upper to position the upper in predetermined relation to the upper shaping means. The means illustrated for use in jigging the material, in which also an important feature of novelty is to be recognized, comprises a presenter adapted to engage the work and move it into predetermined relation to the operating means and then to Withdraw from the work. Still other important features are to be recognized in an organization of means for jigging the material and means for operating upon the material in a manner not only to effect the required shaping operation but also to insure effective control of the material to maintain it in its jigged relation to the operating means. In the machine illustrated the desired results are secured by clamping the margin of the upper in the position determined by the jigging, and further in the course of the upper shaping operation by clamping the intermediate portion of the toe of the upper against the form, and subsequently clamping the upper also about the end of the form while its margin is shaped over the form, thus maintaining an effective control of the jigged upper by clamping pressure in one or more locations throughout the upper shaping operation.
In another aspect the invention presents various features of novelty in an organization of means for shaping the upper materials, comprising a novel construction and arrangement of means for shaping the material about a form and for molding its margin inwardly over the form, the machine illustrated having means for molding the margin of the upper to produce inturned and upstanding portions adapted to conform substantially to the feather and the rib of a welt shoe insole. Among its other features, the invention provides novel means for clamping and controlling the margin of the upper an novel means for wiping the upper heightwise of the form and for clamping it about the form. As applied to an organization wherein the upper is permitted to set until it has acquired permanently the shape imparted to it, the invention further provides for relaxing the clamping pressure about the lateral periphery of the form to avoid marking the upper by the heavy forming pressure. \Vhile the invention, in many of its aspects, is not dependent for utility nor limited to the shaping of uppers oil the last, the machine illustrated is designed for molding the toes of u pers to give them substantially the shape w ich they are to have in the finished shoes before the uppers are mounted on their lasts. Aside from the economies obviously involved in the elimination of the skill and care heretofore required in toe lasting, and the other advantages hereinbefore discussed, this efi'ects also a saving in lasts and other equipment due to reduction of the time the shoes must remain upon their lasts, and by reason of the heavy molding pressure to which the uppers may be sub]ected oil' the last contributes as well to permanence of shape in the finished shoes.
Still another feature of the invention is to be recognized in a novel organization of means for shaping the work and means for trimming it, the machine illustrated having a trimmer which is movable in a predetermined path to trim the upstanding margin of the up er round the toe while the upper is under mo ding pressure. In an organization such as illustrated, in which the upper is jigged to position it in predetermined relation to the upper shapin means, the provision of trimming means re atively to which the upper is also ji ged insures a high degree of accuracy in t e trimming operation. In connection with molding the end of the upper oif the last, a further important advantage in trimming the margin, as required for ex ample rior to the inseam sewing operation, while t e upper is under molding pressure, arises from the fact that the upper is then under better control for the trimming operation than at any subsequent stage in the manufacture of the shoe prior to the sewing of the inseam.
The features of the invention hereinabove discussed, as well as other features involved in various details of construction and combinations of parts not specifically referred to in the above general discussion, will now be more particularly set forth in connection with the aceompanyin drawings and pointed out in the claims. hile the invention is herein illustrated in its application to welt shoe work, it will be recognized that in many of its aspects the invention is not limited to welt shoe manufacture.

\Vhen the end portion of an upper has been shaped about the form as hereinafter described, it should preferably be permitted to set, to insure that when removed from the form it will permanentl retain its molded shape. To assist in hol ing the end of the upper in shape a stiffener may be placed between the leather or cloth forming the shoe upper' proper and the lining. There are various kinds of shoe end stifi'eners which may be advantageously em loyed, but in the present exemplification o the invention a shoe end stiffener that may be rendered pliable by heat or moisture is employed and the illustrated machine is more especially adapted for the treatment of the ends of shoe uppers having stifieners which are rendered pliable by heat.
The machine shown is of the twin type, one of the two mechanisms being adapted to treat the uppers of right shoes and the other those of left shoes, this arrangement also ermitting one upper to set to the molde shape while the other is bein placed in the machine and subjected to mol ing pressure. Except as modified for the treatment of right and left shoes, the two mechanisms are similar in construction and mode of operation, so that a description of one will suffice for both.
The machine frame is of suitable character to support the operating parts, and as shown comprises the side frame members 1 upon which is mounted a top or table portion 2. Extending between the side members 1 is the main driving shaft 3 which may be appropriately driven continuously from any suitable source of power. Preferably the driving shaft 3 is driven by an electric motor 4, operatively associated with transmission shaft 5 connected to the driving shaft 3 through a suitable train of gearing which is typified at 6 (Fig. The train of gearing may be of any appropriate character, the essential in this respect being that rotative movement of the transmission shaft 5 may be transmitted to rotate the driving shaft 3.
Extending transversely of the driving shaft 3 and mounted in suitable bearings 7 and 8 carried by the machine frame is the clutch shaft 9 driven through a train of mechanism from the driving shaft 3. In the present instance the driving shaft 3 has secured thereto a spiral gear 10 which meshes with a spiral "car 11 formed on or secured to a clutch member 12 loosely mounted on the clutch shaft 9. A clutch member 13 is splined to the clutch shaft 9 and is under the control of the workman who may, at will, engage the clutch members 12 and 13, or disengage them, and thereby either start or stop the retation of the clutch shaft. To this end the clutch member 13 is provided with a grooved portion 14 which is embraced by the end portion of an arm 15, Fig. 2, mounted for sliding movement on a guide or rod 16. Connected to the hub portion of the arm 15 is a rod 17 which is connected to a hand lever 18 mounted on a supporting rod 19 held in the machine frame. In the construction shown the hand lever 18 has a downwardlyextending portion 20 which is connected by a link 21 to the shifting rod 17, the construction being such that by manipulation of the hand lever 18 the workman may throw the clutch members 12 and 13 into or out of engagement. The hand lever 18 may be held in the position to which it is moved by means of a bracket or arm 22 having notched portions such as 23, in which the hand lever may catch at its extreme positions. The controlling means thus provided is adapted for use to stop the mac ine at any point in its cycle in dependently of the normal starting and stopping means hereinafter described.
Secured to the clutch shaft 9 is the worm 24, Figs. 1 and 2, which is engaged with a worm wheel 25 mounted on a hub 26, Fi 2. Between the side frame members exten s a cam-carryin rod or shaft 27 on which the hub 26 of t e worm wheel 25 is rotatably mounted. At each side of the hub 26 the rod or shaft 27 carries a sleeve 28 on which cams are mounted for effecting movements of the operating parts of the corresponding half of the machine in the formation of the ends of shoe uppers into their final shape.
The sleeves 28 are independent, and either one may be selectively connected to the hub of the worm wheel 25 for rotative movement therewith by clutch mechanism of any preferred type. In the construction shown each of the sleeves 28 is provided with a clutch pin 29 having a clutching portion 30 adapted to be engaged with and disengaged from a hardened metal ring 31, mounted fast in a Hill side portion of the hub 26, as more clearly indicated in Fig. 2. Each of the clutch pins 29 is provided with an outwardly-extending pin 32 which engages a ring 33 mounted on the corresponding sleeve 28. Each of the rings 33 is normally under the influence of a spring 34 tending to rotate the clutch pin 29 in a direction to engage the clutch pin with the ring 31 in the hub 26 of the worm wheel to effect rotative movement of the sleeve. Each of the rings 33 is provided with two shoulders 35 (Fig. 1) which are adapted to contact with a clutch disengaging member 36 under control of the workman. Since there are twin mechanisms. each of which is to be selectively operated, the clutch engaging and disengaging mechanisms may be similar, and a description of one will sufties for both. In the present instance the member 36 is mounted for rocking movement upon the support 19. Fig. 1, and has a. downwardly-extending portion 37 which is normally under the influence of a spring 38 tending to hold the member 36 in osition for engagement with one of the s oulders It is desirable that after the workman has tripped the clutch disengaging member 36, such member shall move back into position for engagement with the succeeding shoulder 35, without further attention on the part of the workman, and bring the connected sleeve 28 to rest. To this end the downwardly-extending portion 37 has pivotaily mounted thereon at 39 a trip block 40 normally held in the position indicated in Fig. 1 by a spring 41. A treadle 42 is pivotally mounted at 43, and has an end portion 44 adapted to engage and ride over the end of the block 40 when the treadle is depressed; and a spring 45 returns the treadle to its normal position, as indicated in Fig. 1. when the foot of the workman is removed. Should the workman, however, by oversight, fail to remove his foot from the treadle, the trip 40 will tilt after the end 44 of the treadle has passed its operating end, and permit the clutch-disengaging member 36 to return to clutch-disengaging position.
Pivotally mounted at each side of the machine for swinging movement about a cen tre 46 on the top of the machine frame, Fig. 1. is a form carrier 47 having connected thereto at 48 an operating member 49 which extends downwardly and is under control of a cam mechanism on the corresponding sleeve 28. In the construction shown the operating member 49 has a head 50 through which passes the upper end of a rod 51 connected at 52 to an arm 53 mounted on a rod 54 supported at the rear of the machine frame. Extending from the arm 53 is a stud or roll 55, Figs. 1 and 5, which lies within a cam groove 56 formed on a cam 57 carried by the sleeve 28.
When the upper has been laid about the form by the downward movement thereof, and prior to the inwiping movement of the wipers, as will hereinafter more fully appear, it is desirable that the form continue its downward movement far enough to permit the wipers to wipe the upper over the margin-a1 edge portion of the form without inuring the upper, and thereafter to cause the form to press the inturned edge portion of the upper yieldingly against the lower surface of the wipers, and the cam 56 is appropriately shaped to effect these results. To effect the upward yielding pressure of the form against the inturned upper, a spring 58 is interposed between a collar 59 on the rod 51, Fig. 1, and the head 50, the upper end of the rod 51 having connected thereto the collars 60, and the construction being such that after the form has been lowered to permit the inwiping movement of the wipers, the rod 51 will be raised by the cam to compress the spring 58 and yieldingly uplift the form against the overwiped portion of the upper.
Mounted upon the head portion 2 of the machine, beneath the cover plates 61, are wiper holders 62 which carry wipers 63. Guiding slots 64 formed in the wiper holders are engaged by pins 65 passing through the cover plate to direct the movement of the wipers. Each of the holders 62 is connected by a link 66, Fig. 3, to a crosshead 67 having a rearwardly-extending portion 68 (Fig. 1) connected to toggle members 69 and 70 jointed together at 71. The toggle member 70, Fig. 1, is pivotally connected to a yielding abutment which may be conveniently formed by a rod 72 having collars 73 between which and the machine frame 2 is interposed a spring 74, the construction being such that when the toggle is straightened as indicated in Fig. 1, the wiper holders and the wipers will be moved to overwiping position with provision for yield. Adjustable stops preferably in the form of threaded nuts 75 limit the movement of the rod 72 under the impulse of the spring 74.
Connected to the toggle at the joint 71 is the toggle-operating means which, in the construction shown, comprises a head 7 6 and an adjustable toggle operating rod 77, Fig. 1. The lower end of the operating rod 7 7 is connected at 7 8 to an arm 7 9 pivotally supported by the rod 19. To impart ope rative movement to the rod 7 7 and the wipers. the arm 79 carries a stud or roll 80, best shown in Fig. 4. which lies in a ram groove 81 formed in the side of a cam wheel 82, Figs. 2 and 4. It may be desirable in some cases to limit the breaking movement of the toggle, which may be appropriately efiected by means of a stop 83, Fig. 1, adjustably mounted in the head 76 and adapted to engage a. projection 84 secured to the top portion 2 of the frame.
For purposes of the present invention there PHI is provided means for jigging the upper to position it in predetermined relation to the form by engagement with the upper In jig holes formed in its margin at opposite sides of the toe in redcter'mined relation to a characteristic the upper. The predetermined position of the end of the upper relatively to the form when the upper is placed in the machine is secured, in the construction shown, by the aid of a presenter which is constructed and arranged to support the upper in inverted position. The wipers 63 are each provided with co-operating positioning means which, in the present instance, are in form of slots the walls of which are adapted to be enga "ed by portions of the presenter to position the upper. The presenter may be variously constructed, but .as shown it comprises the two side arms 86 which are arranged a suflicient distance apart to permit the entrance of a portion of the upper. At the forward end of each arm the presenter has a projection or upper engaging portion which, in the present instance, comprises a pin 87, Fig. 12, the ends of the pins being reduced in diameter for engagement in the ji holes in the upper. The two portions 86 o the presenter may be extended to form a handle portion 88, Fig. 23, at the rear of the upper as a convenient means for manipulating the presenter to place the upper in the machine. The presenter may be constructed of resilient metal to adapt it for uppers of different shapes and sizes.
The upper which is to be placed in the machine is provided with positioning surfaces which are preferably formed by jig holes 89 made in the upper at separated points located at predetermined distances from a datum point, as for instance, the back centre line of the upper as at 90, Fig. 23, the construction being such that if all shoe uppers of the same size and style are provided, with similarly located jig holes and the uppers are presented to the form by reference to such ig holes, the length lateral position, and angularity of the'molded ends of all the uppers of the series will be identical. Where the end of the upper is provided with a tip 91 which is secured to the vamp 92 by fastenings, as indicated in Fig. 22, the jig holes 89 may be formed on the vamp at predetermined distances from the back centre, and on the tip at predetermined distances from the front centre, such that when the tip and the vamp are assembled together, and the jig holes of the vamp and the tip are brought into matching relation, the length, lateral position, and angularity of the tip with reference to the vamp will be determined. As indicated in Fig. 22, the jig holes 89 may advantageously be formed between the lines of stitches which secure the tip to the vamp.
In presenting a shoe upper to the machine for treatment, the jig holes 89 in the end of the u per are engaged by the projecting pins 87 0? the presenter, and the main portion of the upper at 93 will extend between and be supported by the side members of the presenter substantially in the position indicated in Fi 23. With the upper in predetermined relation to the resenter, the workman has simply to move is e presenter to bring the pins 87 thereof into the positioning slots 85 of the wipers until the pins engage the locking end portions 94 of the slots, which thereu on automatically determine the relation 0 the presenter and wipers, and consequently the position of the outspread upper with relation to the form. In order to assist in guiding the presenter and its supported upper into proper relation to the wipers, there are provided on the ins 87, in the construction herein shown, le ges 95 which are spaced below the upper supporting shoulders on the pins a distance substantially equal to the thickness of the wipers and are arranged to engage the lower surface of the wipers as the pins are moved inwardly along the slots 85. The relation of the presenter and the upper to the wipers when the upper is in position for the molding operation is indicated in Fig. 11.
When the end of the shoe upper has been placed in predetermined position with relation to the form, as above described, it is desirable that the upper be freed from the presenter and clamped in position for treatment by the machine. In the construction shown the outspread upper is held upon the top surface of the wipers by clamps, which as they are moved to operative or clamping osition, assist in disengagin the presenter mm the upper. The action 0% the clamps is preferably made yielding, so that the marginal portion of the upper may be partially withdrawn from between the clamps and the wipers as the upper is laid about the form.
The clamps for holding the marginal portion of the upper upon the wipers may be in the form of plates 96, Figs. 3, 11, 13 and 15, arranged to co-operate respectively with the different wipers. While in some cases it is not necessary, yet it is preferable to form the clamping plates 96 so that when they are in clamping position they will exert a substantially continuous clamping action round the end portion of the upper which is to be molded; and since the two clamping members on each of the twin machines are identical, a description of one will be sutiicient.
Secured to and movable with the wiper holder 62 is the stud 97, Figs. 3 and 11, which passes through an elongated slot 98, Fig. 3, formed in the cover plate 61. If desired, a slide 99 may be carried by the stud 97 to cover the elongated slot 98 more orless as the wiper plate and the stud are moved relatively to the cover plate. Connected to the stud 97 is the clamp carrying arm 100 which has an elongated slot 101 engaging a cross pin carried by the stud. Pivotally mounted on the end of the arm 100 at 102, so as to maintain at all times a substantially parallel relation to the plane of the wipers, is the clamping plate 96. A link 103 extends between the arm 100 and a stud 104 mounted on the wiper holder, and is normally in an inclined position when the clamp carrying arm 100 IS raised, as indicated in Fig. 11. When, however, the clamp carrying arm 100 is depressed, as will be presently described, the link 103 serves to move the clamp 96 inwardly and bring it into closer relation to the edge portion of the wiper, with which it co-operates. An advanta e in thus engaging the margin of the upper by the clamps close to the edges of the wipers is that uppers may be cut as small as is consistent with other operations of the molding mechanism without interfering with the proper function of theclamps. By reference to Fig. 13 it will be noted that when the clamps are in clamping osition the links 103 are still inclined to the horizontal, and consequently the subsequent withdrawing movement of the clamps is outward from the edge of the form as well as upward. This insures that the clamps will. not interfere with the margin of the upper which may in the final retracting movement of the clamps project upwardly inside of the inner edgesof the clamp members.
The clam -carrying arm 100 is preferably constructed with two side members, as indicated in Fig. 3, and through the space separating the side members extends a stud 105 which is secured to the wiper holder 62. Between the two side members 100 constituting the clam -carrying arm, is the sleeve 106, Fig. 21, aving the upper and lower flanges 107 and 108, the construction being such that should the sleeve 106 be raised or lowered, it will operate upon the clamp carrying arm to similarly move the clamp. The sleeve 106 has an upwardly extending portion 109 provided with slots 110 into which project the ends of pins 111, Fig. 20. The pins 111 are carried by a sliding member 112 to the upper end portion of which is adjustably connected a cap piece 113. Mounted in a socketed portion of the stud 105 is a spring 114, the normal tendency of which is to lift the sleeve 106 and to correspondingly lift the associated clamp carrying arm 100. Between the lower end of the cap piece 113 and the top of the sleeve portion 109 is a spring 115 which, when compressed by the downward movement of the cap piece 113, yieldingly forces the sleeve 106 downwardly to carry the clamp into clamping 081161011.
T e present invention provides means for automatically operating the clamps to the end that when the presenter has moved the end of the shoe upper into predetermined position relatively to the form, the clamps may be operated to clamp the marginal rtion of the outspread upper and to move t e presenter in a direction to disengage it from the upper. Clamp-operating arms 116 are pivotally mounted on the top of the machine frame at 117, Figs. 1 and 3. In the present instance, the operating arms 116 are carried by a sleeve 118 which is mounted for rocking movement about the axis 117 and has a rearwardly-extending arm 119, Figs. 1 and 3, to which is connected one end of an operating rod 120, the lower end of which is connected at 121 to an arm 122 mounted for rocking movement on the support 54, Figs. 1 and 4. The arm 122 has a pin or roll 123 which is engaged by a cam formation 124 on the peripheral portion of the cam wheel 82, Fig. 4, the construction bein such that upon rotation of the cam the clamps will be moved to and from operative position. A spring 125 interposed between a stop 126 and a collar 127 on the rod 120 serves to hold the roll 123 in engagement with its operating cam. To facilitate adjustment of the movement of the clam s, the rod 120 may be adjustable in lengt as by a turnbuckle, as shown in Fi 1.
Each operating arm 116, Fig. 3, has a s otted end portion 128 through WlllCh extends the sliding member or sleeve 112 which, as hcreinbcfore described, compresses the spring 115, Fig. 20, when the member or sleeve 112 is depressed, to effect a yielding clamping action of the clamp. As indicated in the sectional illustration of Fig. 20, the operating arm 116 normally rests upon the pin carrying lugs which project outwardly from the sleeve 112 and when the operating arm 116 is moved downwardly, it carries with it the sleeve 112, compresses the spring 115, and efi'ects the downward, yielding clamping action of the clamp upon the upper. To insure the lifting movement of the clamp, the cap piece 113 ma have associated therewith a collar 129, Fig. 20, provided with an outwardly extended portion 130 adapted to be engaged by the operating arm 116 as the latter is raised through the train of, mechanism hereinbefore described. Adjustment of the cap piece 113 ma be effected to vary the tension of the spring. While the means described for operating the clam s is found to be a good, practical form of t is feature of the invention, yet variations may be made therein, it being desirable, however, that the clamps, as shown, be automatically operated to effect the clamping action u on the marginal portion of the upper an to release it at predetermined times, as will be more fully described. 1
Where the clamps, as in the construction shown, comprise plates such as 96, which extend continuously for some distance about the end portion of the shoe upper, it is sometimes desirable to connect the clam s at their ends to the operating arms, as we 1 as at an neoaase intermediate oint such as hereinbefore described. To this end each operatin arm 116 carries a sleeve 131, Fig. 15, whic is confined to the arm 116 by a stop screw 132. Within the sleeve 131 is a plunger 133 upon which rests the lower end of a spring 134, the tension of which may be varied by a threaded adjusting cap 135. Against the plunger 133 rests the upper end of a pressure-transmitting member 136, the lower end of which is connected by a ball and socket joint 137 to the outer end portion of the clamp 96. The construction is such that when the operating arm 116 is moved downwardly to e ect the clamping action upon the marginal portion of the u er, the outer end portion of the clamp wil e moved downwardly under the yielding action of the sprin 134 and insure, for example, a substantia ly equal clamping action on the marginal portion of the upper throughout the clamping surface of the clamp. On the other hand, it may be desired on some work to clamp the margin of the upper harder at some points than at others, for example to apply greater clamping pressure at the opposite sides of the form, at or near the location of the ti seam, than round the end of the form. his may be done in the construction shown b the independent means provided for ad uSting the different springs 115 and 134.
When the form and the margin controlling means are relatively moved to lay the upper about the form, the clamps have a suflicient retarding action upon the withdrawal of the upper to insure its being drawn closely over the form. When, however, the wipers are operated to wipe the upper inwardly, and thus to lay the marginal portion of the upper over the bottom of the form, if the clamping pressure of the clamps were still maintained on the upper, or if the full force of such ressure were maintained, the wipers would liable to injure or tear the up er, especially with some kinds of upper stoch. Therefore the invention, in its illustrated embodiment, provides such an arrangement of wipers and clamps and their operating mechanism that during the time the upper is being laid about the form, the clamps will yieldingly retard the withdrawal of the upper; but before the wipers receive any substantial inward movement to wipe the marginal portion of the upper over the bottom of the form, the clamps will be caused by the cam 124 to release the upper substantially from clamping pressure. By reference to Fig. 17 however, it will be seen that the clamps do not receive at once their full withdrawing movement, but remain in position to bend the margin of the upper outwardly over the wipers While the wipers are closing, thus contributing to effectiveness of the wipers in wiping the upper smoothly and tightly inward over the form.
Substantially accurate conformation of the upper with the surface of the form is essentla to insure uniformity in the shape and condition of a line of shoe uppers molded about the form; and while the action of the clamps insures to a degree that the upper will be laid properly about the form, the invention further provides for working the upper heightwise of the form by pressure against the u per about the end of the form. This may t be effected by subjecting the portions of the upper which are about the lateral periphery ot the form to the rubbing or wiping pressure of an embracing clamp or band, though other forms of means may suggest themselves within the scope of this feature of the invention. In the present instance band carriers 138 are uided for movement in slots 139 formed in t e head portion 2 of the machine frame. The band carriers 138 carry the band support or backing 140, Fig. 6, comprising opposite side portions to which the band 141 is secured. The band may be of leather or other material suitable for the urpose. The band carriers are connected or pivotal swinging movement about an axis 142. Each of the band carriers 138 is under the influence of a spring which normally tends to separate the band carriers as indicated in Fig. 6. In the present instance the band carriers are provided with pins 143 to each of which is connected one end of a spring 144, the other end being secured at 145 to a fixed point in the machine, the construction being such that the springs 144 normally tend to open the end band.
Each of the end band carriers 138 has associated therewith an adjusting screw 146, Fig. 6, the rear end portion of which bears upon a sliding block or plunger 147 mounted for sliding movement in the head frame 2. Extending backwardly from the blocks 147 are links 148, the rear end portions of which are connected to the upper end portions of arms 149, Figs. 6 and 10, mounted upon a rock shaft 150. Extending from the rock shaft is an operating arm 151, Figs. land 10, to which is connected an operating rod 152, Figs. 1 and 4, the lower end portion of which is con nected at 153 to an arm 154 mounted for oscillating movement upon the support 19 and carrying at its outer end a cam follower or roll 155 which projects within a. cam groove 156 formed in the face of the cam 82, the construction being such that as the cam rotates, the end band, which is indicated as a toe band, will be opened and closed as will more fully appear.
Since the end portions of shoe uppers will vary in size and shape in accordance with the size and style of shoes, provision is made in the present invention for accommodating the toe band to such variations. In the construction shown the pivotal connection 142, Fig. 6, between the end band carriers, is carried by a link 157 which in the closing and opening of the band slides in a slot formed in the head frame of the machine and is ivotally connected at 158 to an operating ever 159 pivoted at 160 to a sliding carrier 161 which is guided by a pin and slot guiding means 162 for endwise movement. The sliding carrier 161 is pivotally connected at 163, Fig. 10, to one of the arms 149 which operate the end band carriers, so that the band will be moved lengthwise as well as opened or closed laterallv. The end 164 of the lever 159 is connected to an adjusting rod 165 which has at its front end a threaded connection 166 with an adjusting nut 167. A spring 168 is interposed between a collar 169 on the adjusting rod 165 and the top frame 2 of the machine, the construction being such that the spring 168 normally forces the end 164 of the lever 159 rearwardly to position the pivotal connection 142 of the end band carriers, and by adjustment of the stem 165 the initial position of this pivotal connection may be varied. Corresponding adjustments of the band carriers about the axis 142 may be effected by manipulating the screws 146. By these different means the band may be positioned to co-operate properly with different shapes and sizes of forms over which uppers are to be molded. By reference to Fig. 6 it will be noted that the link 157 is permitted to have a limited lateral movement in the slot through which it extends, and provision is thus afforded for bodily lateral movement of the band in one direction or the other to accommodate itself to the form as the latter is forced downwardly within it. It will be evident that the band carriers are unyieldingly positioned against lateral swinging movement and against movement lengthwise of the form in response to the forming pressure. thus maintaining the band in unvary ing contour throughout the upwiping operation.
The form 170, Figs. 7, 8 and 9, has a forming surface corresponding substantially to the shape that the shoe upper is to have in the finished shoe; and on its bottom face a marginal edge shoulder 171 extending inwardly a short distance from the outer edge of-the form. At the inner portion of the shoulder 171 the form is provided with a raised portion or shoulder 172, the construction being such that when the upper is wiped in by the wipers it will be laid upon the shoulder 171 of the form to provide an inwardly extending shoulder on the upper, and the edge portion of the upper will be compressed or molded about the central raised portion of the form to provide an upstanding marginal flange.
In the present instance the form 170 is mounted upon the form carrier 47 and is preferably detachably connected thereto. As shoivn, the form has in its bottom, which is uppermost, a hollowed portion 173, Figs.
7 to 9, and an inwardly-extending flange 174 beneath which is adapted to en a collar 175 formed on the lower end of a orm-securing rod or stem 176. The n per end portion of the securing rod is provi ed with a screw thread 177, which is engaged by an adjusting nut 178. The rod 176 extends through a bushing 179, the lower end portion of which is formed witha shoulder 180 adapted to engage the top surface of the flan e 174 extend- 1ng inward y in the recess 17 3 o the form, the construction being such that when the flan e 174 is placedbetween the collar 175 and the shoulder 180 of the bushing, and the ad'usting nut 178 is manipulated, the form will be secured in operative position on the form carrier. The described detachable connection between the form and the form carrier resents a convenient and ready means for e ecting a chan e in forms, but the particular means may varied.
As the u p er is molded about the form, the latter is su jected to an endwise pressure outwardly or toward the heel end of the upper. The present invention provides additional means for counteractin such pressure against the form by a brace adjustably connected to the form carrier. In the construction shown a brace or abutment 181, Figs. 1 and 7, is pivotally mounted at 182 between arms 183 on the form carrier 47. The lower end portion of the brace 181 is provided with a lug 184, the inner face of which, when the brace is in bracing position, bears against the front end face 185 of the form. An adjusting screw 186 bears against the end of a hardened plug 187 in the form carrier, and serves as a means for varying the bracing effect of the brace.
In forming or molding the end portions of shoe uppers where the stifi'ener is made pliable b heat, it is sometimes desirable that the end 0 the upper be subjected to the action of a softening heat during molding, suflicient to permit the stiffener to be molded into close conformation with the form. In the present instance the form may be heated by one or more heat units. In the construction illustrated two such heat units 188, Fig. 9, are indicated. These extend into a suitable cavity made in the form and are connected to wires 189 which may be conveniently directed along the form carrier 47.
While the upper is being subjected to the upwiping action of the end band and being laid or stretched about the form under the tensioning action of the clamps and wipers, the uniformity of the final product demands that the upper be held from displacement on the form; and one of the features of the present invention has this in view. In the present instance there is provided an abutment or pad to engage the to or intermediate portion of the toe end of the upper and between which and the form the upper is held during the operation of conforming the upper to the form. Adjustably mounted in the head portion of the machine frame is an arm 190, Fig. 1, which may be secured in position by a set screw 191. The arm 190 carries a casing 192 in which is mounted a plunger 193, Figs. 1 and 11, normally held in an upward position by a spring 194 within the casing. the upper end of the spring bearing upon the plunger 193, and the lower end resting upon an adjustable sleeve 195, whereby the action of the spring in transmitting pressure to the plunger 193 may be varied. The spring 194 may be suitably held in place by a rod 196 secured to the plunger 193 and extending loosely through the adjusting member 195. Turning movement of the plunger is prevented by a lug 197 which projects within a slot 198 in the casing, and its upward movement is limited by engagement of a nut on the end of the rod 196 with the member 195.
Pivotally connected to the top of the plunger 193 at 199, Figs. 1 and 16, is the rest 200 which carries a pad 201 having a surface corresponding to the contour surface of the opposed portion of the form. Springs 202, Fig. 16, normally hold the rest 200 in a predetermined horizontal position with provision for tilting movement to conform to the surface engaged by the pad. The construction is such that the unconfined portion of the upper is depressed by the form into engagement with the pad 201 which, under the action of the spring 194, assists in preventing displacement of the upper relatively to the form as the upper is being laid and wiped about the form.
When the upper has been molded about the form, it is permitted to remain in molded position on the form for a considerable length of time to afford an opportunity for the upper to set in the permanent shape it is to have in the finished shoe. If, during this time, the end band remained in pressing contact with the upper, it would be liable to mark the surface of the upper, due in part to the softened condition of the end stiffener. The present machine provides for relaxing or removing the pressure against the upper while it is permitted to set; and to this end the mechanism for operating the end band is so constructed and arranged as to relieve the pressure of the band soon after the upper has been fully laid about and wiped into conformation with the form, as represented in Fig. 1.9.
The machine is further provided with means for trimming the upstanding marginal flange of the upper about the toe end while the upper is under control of the molding means, to prepare this portion of the upper for the inseam sewing operation. The trimming means in the construction shown is associated with the form, and is supported in position to trim the upper substantially in the plane of the to surface of the Wipers when they are in t eir inner position and are holding the upper. The trimmer may be variously constructed but in the resent instance it is formed as a blade 203, i s. 7 and 8, carried by a sleeve 204 rotatable a out the stem 176 and supported in such position that the surplus upper stock wiped in by the wipers will be brought into the field of action of the trimmer. The sleeve 204 is mounted on the lower end portion of the bushing 179 and is power operated at times for eflecting the trimming operation. Mounted upon the bushing 179 above the sleeve 204 of the trimmer is a pinion 205 which is in operative engagement with a pinion 206 mounted on a shaft 207 extending through a suitable hearing formed in the form carrier 47. At its upper end the shaft 207 is rovided with a pinion 208 which is engaged by the teeth of a rack 209, Fig. 7, receiving reciprocating movements at the desired times for operating the trimmer through a train of mechanism operated by a cam on the sleeve 28. In the present instance the rack 209 is connected by a link 210, Fig. 1, to an arm 211 pivotally mounted at 212 upon the form carrier 47. Connected to the arm 211 is a downwardlyextending arm 213 which is connected by a link 215 to a bell-crank lever 214. The bellcrank lever 214 has connected to it at 216 an operating rod 217, the lower end portion of which is adjustably connected to a cam operated arm 218 mounted upon the support 54. The arm 218 is provided with a cam follower or roll 219 which travels in a cam groove 220, Fig. 4, formed in the face of the cam wheel 82, the construction being such that the rack 209 Will be reciprocated by rotation of the cam to impart to the trimmer its operating movements.
Whcn the end of the shoe upper has been molded t the shape which it is to have in the finished shoe. the shoe is to be lasted. During the lasting operation, it is desirable to subject the upper to a lasting pull at the tip line or where the tip is secured to the vamp. Therefore the trimming means as herein shown is constructed and arranged to make a trimming cut from a point in front of the tip seam at one side of the end of the upper to a point in front of the tip seam at the opposite side; and since the size, form, and relation of the tip to the vam may vary in different styles and sizes of s oes, provision is made for adjusting the trimming means to effect its described purpose upon shoe uppers of different sizes and styles. This may be variously effected, but in the present instance the arm 218 for operating the trimmer is provided with an end ortion having a series of openings 221 to wliich the lower end of the operating rod 217 may be selectively connected, the effect being that the trimmer will be given movements of greater or less amplitude. The point where the trimmer terminates its cutting movement may thus be varied to correspond to the requirements of difierent styles and sizes of shoe up ers, as indicated for example by Figs. 24 an 25 where the cutting movement of the knife ends at 224 and 226 respectively, in front of the tip seam 223. A corresponding variation with respect to the point (222 or 225) where the knife begins its out at the opposite side of the upper may be eifected, when necessary, by substituting a knife of different length, the machine being so constructed that different knives ma be readily substituted. The knife is adapte to trim the upper as required by a single cuttin movement, but t is immediately returned to its starting position, and for further effectiveness in making a clean out along the margin of the upper it is provided with cutting edges on its opposite sides. It will be evident that the trimming knife in the construction shown cuts in a single plane and does not sever from the upper the rear ends of the band of waste material which it trims ofl' round the toe. This avoids all danger of clogging or otherwise interfering with the o eration of different parts of the machine by t e accumulation of scrap material. After the u per has been removed from the machine the and of material which has been trimmed off round the toe may be severed from the upper by the use of a hand knife or by other convenient means.
The upper stock will vary in thickness, and since the trimmer is to trim the upstanding flange of the upper in the plane of the upper surface of the wipers, means are provide to insure that the trimmer will operate to trim the stock in the desired relation to the wipers, regardless of variations in the thickness of the stock and consequent variations in the position of the form after the upper has been wiped in by the wipers and after the form has been pressed yieldingly upward. In the present instance the sleeve portion 204 of the trimmer is provided with a circular groove 227, Figs. 7 and 8, which is embraced by an arm 228 removably secured in a head 229 on the end of a carrler 230, Figs. 1 and 7, mounted on the pivotal support 46 of the form carrier at 231. The head 229 is'connected to a stem 232, Fig. 7, which extends upwardly through the form carrier with a sliding lit, suitable stops such as nuts 233 bein provided to adjustably limit the downwar movement of the head 229 under the action of a spring 234 interposed between the carrier 47 and the top portion of the head 229. Mounted in the cover plate 61 which overlies the wiper holders 62 is an adjustable stop 235 which is adapted to be en aged by a lug 236 carried by the head 229 w en the form carrier 47 is moved downwardly to lay the upper about the form. The construction is sac that when the form and the wipers are relativel moved to lay the upper about the form an to compress its marginal portion between the form and the wipers, the cutting plane of the trimmer is automatically determined irrespective of the position of the form.
In order to ermit the trimmer to be readily removed w ien desired, the arm 228, Fig. 7, is made detachable from its connection with the trimmer by means of a spring clip 237. Upon lifting the clip 237, the arm 228 may be moved backwardly 111 the head 229 and disengaged from the trimmer, whereupon the thumb nut 178 may be loosened to permit detachment of the form and subsequent removal of the trimmer.
W'hen the end of a shoe u per has been formed and trimmed, as herein efore indicated, it is liable to stick or adhere to the form after the upper has set; and to meet this condi tion the present invention provides for detaching the finally shaped and molded end of the upper from the form. In the present instance a detacher is provided, consisting of a stem or plunger 238, Figs. 8 and 9, having a headed portion 239 normally held retracted in a slot formed in the end portion of the form by means of a spring 240 interposed between the surface 185 of the form and a. head 241 on the plunger, the construction being such that after the end of the upper has been molded and set to the form and the form has been moved to its inoperative position, a push upon the head 241 of the plunger will serve to move the molded end of the shoe upper endwise of and detach it from the form. To avoid interference with the lower end of the stem 176 which co-operates to hold the form on the form carrier, the lower end portion of the stem 176 is slotted from its bottom surface upward and the stem or plunger 238 extends through such slotted portion.
A shoe upper formed in accordance with the resent disclosure and adapted more particu arly for welt shoes, is shown in Fig. 26, wherein it will be seen that the toe end of the upper is molded or formed to the final shape it is to have in the finished shoe, and is provided with an upwardly extending marginal flange 243 of a height substantially corresponding to the height of the lip of the insole to which it is to be attached. the trimmed portion of the flange terminating preferably at points in front of the tip line to provide adjacent to the tip line the extensions 244 for use during the lasting operation. The flange 243 as thus molded is in position to lie in close conformity to the rib of the corresponding shoe insole and extends upwardly from a portion which is molded over the surface 171 of the form to lie on the feather of the insole.
In the use of the machine shown, the workman positions the inverted upper on the presenter by engaging the end portions of the presenter with the jig holes in the upper, as shown in Fig. 23, and then moves the presenter to carry the upper into operative relation to the form. In doing this he moves the pins on the presenter into the slots 85 in the wipers until the pins interlock with the otl'set portions 94 of the slots, and when the presenter has finally reached the position thus predetermined by the positioning slots in the wipers, the shoe upper assumes a predetermined posit-ion relatively to "the form. This condition is represented in Fig. 11, at which time it will be noted that the clamps 96 are in their raised or open position. The workman thereupon treadles the machine, the first efiect of.which is that the clamps de scend and engage the marginal portion of the upper and press it yieldingly against the top surface of the wipers, and at the same time press downwardly upon the holding pins of the presenter and assist theoperator in effecting its detachment from the upper,
the ends of the pins being preferably somewhat rounded to permit them to slip out readily when they are pushed down. The upper is then ositioned in the machine and held in its prec etermined relation to the form between the clamps and the wipers. During the'downward movementof the clamps, the links 103 move them also inwardly to bring their edge portions in close proximity to the edge portions of the wipers, substantially as re iresentedin Fig. 13. The end band is at this time in its closed position, ready to act with wiping pressure upon the upper toward the bottom 0 the form. The form thereupon is moved downwardly upon the unconfined portions of the end of the upper and the toe pad 201-engages and holds the upper from displacement about the form. As the form continues to descend, the marginal portions of the upper are partially withdrawn from the confining means or clamps, the upper is laid about. the form with an upper stretching pull, and the end band simultaneously acts towipe or work the upper heightwisc about the end of the form, substantially as indicated in Fig. 16. The downward movement of the form is continued until the shouldered portion 171 of the form is slightly below the lower surface of the wipers, whereupon the wi pers are automatically moved inwardly to gather and lay the upper over the bottom of the form and-to mold it into an upstanding flange against the shoulder 1T2. Prior to anysuhstuntiul inward movement of the wipers the clamps areautomaticallyoperated to relieve the nuu'gii'ial port ions of the upper from clnn'iping pressure. substantially as indicated in Fig. 17. After the wipers have wiped in the marginal portions of the upper. and while the upper is still held between the form and the rest. 201 and subjected to the pressnre of the end hand, the form isslightly raised under the action of the spring 58, Fig.
'1. to rcss the u )er firmly against the bot tom surface of tie wipers. whereupon the a plurality of jig trimmer is' automatically operated to trim of time to permit the u per to set to the final shape it is to have in t to finished shoe, during which time an upper may have been presentedand molded in the other portion of the machine, the workman again treadles that. part of the machine in which the first upper was molded, whereupon the .wipers move out wardly and the form riScs'carPying the end of the shoe upper, which may be detached fromthe form by the detacher. Justprior to the conelusionof the second ortion of the cycle of operations,the end ban is moted inwardly so that at thebeginning of another operation-for molding the end'of a shoe upper the band willbe in position to effect its upwiping and rubbin pressure upon the upper.
Certain novel method aspects of the procedure hereinbefore set forth relating especially to the present-ationof the work to the operating means and tothe trimming of the u per, are covered by claims in a divisiom application Serial No. 134,7 11, filed on September 10, 1926. Furthermore, in respect to the jigging of the upper, the organization herein shown and described is constructed ,to carry out a method claimed in a copending application of George E. Yl'arren, Serial No. 446,659, filed on June 11, 1921.
