ItNSOLE-REENFORCING- MACHINE,

Application filed J111 y23, 1919. Serial No. 312,662.

To all 10710421 it may cone-wt:

Be it known that I. TrroMAs H. 531mm, a citizen of the United States, residing; at Malden. in the county of Middlesen and State of'Massaohusetts, have invented certain new and useful Improvements in Insole-Beentoreing M aehines; and I do here by declare the following; to he a full, clear and. exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. V

The present invention relates to machines for opera tine upon insoles and more particularl x to machines of this type emploved for operation upon composite insoles having' a layer of reenforeine' material which serves to strengthen the rib or lip of the insole.

The pausentinvention is designed primarilvto facilitate the application of the reenforoing material to what are known as Gem insoles. In the manufacture of in soles of this tvpe as now commonly practised the reen oreiner material, after being initiallv positioned upon the insole. is formed over the inside and outside of the lip an d trimmed to correspond with the corn tour of the sole after which the sole is sub-- ieeted to a rih tio hteninq operation to force the mat rial into engagement with the base o'l the lip and perhaps ineidentallvshape the lififl'Ffii'iOfl he or rih to the desired form and an' le relative to the fare of the sole.

it is an olojevt of the present invention to provide an insole reenforeingr machine which shall eoi'nplete in a single operation the applieation ofthe reenforoine' fabric to the insole after the fabric has loeen initiallv positioned thereon the machine etteotnallv' forming and tiojhteninq the fabric about the insole lipf in such a manner that the reent'orr-ed insole thus produced is immediately aroilahlo for ineorporati on in a hoot or shoe. A. further ohieet of the present invention is to inn'irove the fahri severing mechanism iuysueh a manner that the fabric is cleanly and accurately trimn'ied on a line lying within the margin of the sole to avoidanv possihijlitv otjlater exposing the fabric in the completed shoe.

With these ohieets inview the several features of the invention consist in certain novelfeatures of construction. combinations.

and arrangements of parts hereinafter described and claimed, the advantages of which will he ohvious to those skilled in the art from the following description.

. In the drawines illustrating the preferred form of the invention. Figure 1 represents a side elevation partlv in section of a machine emhodving the several features ofthe invention with the tools in position for en tel-inn a sole: 2 is a front elevation of the machine with a portion taken in section upon the line 2-2 of 1: Fig. 3 is a longitudinal section of the machine taken upon the line 33 of Fig. 1 with the worl; tahle and cooperating: parts removed; Fia 4- is a side elevation upon an enlarged scale illustrating the inside former and operatin; mechanism and showing the position of the lip at the completion of the reenforoinr; and rib tie'htenine'or setting operation: 5 is a detail illustrating portion of the mechanism for driving: the rotary lrnifef and Fi -16 is a detail illnstratino' a portion of the moehanisu'i for operating the under ehttinlq blade in amordan e with the lateral move ments of the rotarv knife,

The illustrated emhodiment ofthe invention is eonstru ted, alone the general lines of the. maehine dis 'losed in the patent to l-ladawav No. 614 60. November 539. 1898. and in eertain d R utilises the idehtiral eonstruotion of this machine. For example. the sole is snp 'iorted upon a rotary tahle i0 iournaled in a head ll projecting; lFIiJQVHllV from the maohine frame 12 and rotated .int rmittentlv to feed the sole through a ratohet wh el 13 and driving pawl 14. This dri inn; pawl is oscillated from a cam path 16 throne-h a hell orank l8 havina a toothed. ooni no formed upon the end, of one arm which meshes with a similar sesrment 20 formed upon one arm of a horizontal hell oranlr eonnec'ted to the pawl through a linl: The under-former which engages with the outside of the insole lip and over whi h the reenforoino; material passes is in eated at and is connected withthe wort table through the usual connections. partlv hrolren awavin the drawingrsto cause a depression of the former with thework talole to permitthe insertion and removal of the work. This former and the accompanying connections are shown more particularly in Figure 2 of the drawings. The above construction is identical with that disclosed in the Hadaway patent hereinbefore referred to, although in the present machine the under former serves as a rib gage for guiding the insole through the machine.

After the work has been located upon the table and the latter elevated into o'pera tive position the reenforcing fabric is engaged by an inside former which serves to initially tuck the fabric against the inside of the lip, drawing this fabric from the outside over the under-former 25. Thus the inside former delivers a relatively light blow the purpose of which will appear later. Thereafter the fabric is engaged upon the outside of the lip by a feeding former or foot which draws the fabric down against the outside of the lip and presses it against the feather. This feeding former is then moved laterally in synchronism with the rotary movement of the table to feed the work. A feeding movement is also imparted to the inside former at the same time, it having previously been withdrawn from e11 gagement with the lip, and at the completion of the feeding movement a second advancing movement is imparted to the inside former to deliver a relatively heavy blow and complete the tucking of the fabric into the apex of the angle at the inside of the lip. While the work is thus held stationary between the table and the inside former the feeding former is withdrawn and an outside former is advanced into engagement with the work to complete the shaping of the fabric to the rib and in addition to bend the reenforced rib into an inclined position relative to the plane of the sole body. This construction serves to lay the reenforcing fabric closely on opposite sides of the lip and at the same time permits the desired final shaping of the rib to facilitate subsequent operations, more particularly the lasting and inseam sewing.

The inside former, indicated at 30, is supported upon the lower end of the lever 32 fulcrumed at 33 upon one arm 35 of a bell crank leverfulcrumed upon the frame of the machine at 36. The second arm 37 of the bell crank lever is provided with a cam roll 38 received in a cam path 40 formed in the main cam disc 42. The upper end of the lever 32 which carries the inside former is connected to a stationary arm through a link 44. lVith this construction the oscillatory movements of the bell crank having the arms 35 and 37 serve to move the inside former 30 upon an arcuate path so controlled by the link 44 that the former during its advancing movement will enter the apeX of the inside angle at about the time itreaches the bottom of its are, as shown in Fig. 4. The pressing movement is thereafter in direction parallel to the face of the sole and applies the reenforcing fabric tightly in the angle without disturbing the upper portion of the lip. It is particularly pointed out that the tucking movement of the former 30 is positive, there being no interposed springs whatever in the operating train, but the action is so adjusted as to apply just the amount of pressure desired as will now be explained.

In order to vary the path of movement of the inside former and in addition the inner and outer limits of movement as desired, the link -4: at the upper end of the lever 32 is adjustably connected with the stationary arm 43 through a block slidingly received in a transverse slot 52 formed in the arm into which is threaded an adjusting screw 54: having a head held against longitudinal movement in the slot as shown in Figures 2 and 4. The link 4-4 is pivotally connected to the block and a rotation of the adjusting screw serves to move the block in and out in the slot to vary the angular position of the lever 32 about its pivot 33. In addition the angular relation of the two arms and 37 of the bell crank may be varied through the provision of an adjusting screw 56 threaded in a boss 57 formed upon the arm and engaging with the arm 87 adjacent the fulcrum 36 of the bell crank. The two arms are normally main tained in any adjusted relation through the provision of a split hub 58 forming a part of the arm 35 and having the two portions clamped together by a bolt 59. This split -hub 58 embraces a shaft 60 projecting from the hub of the arm 37. The inside former is adjustably secured to the lever 32 through the provision of an elongated slot 62 which receives a cap screw 63 threadedly secured in the lever, an adjusting screw 64 threaded in a lug 65 on the lever serving to move the former when the clamping bolt 3 is released. As will be obvious from an inspection of Fig. 2 the inside former 30 is connected to the lever 32 through tongue and groove connections which preserve the proper alined positions of the two members.

By means of the adjustments just described the throw and path of the inside former may be set to accommodate any type of sole on which the machine is to act. In Gem work the variations in lip thickness are taken care of by the adjustable block 50, the change in heightbeing compensated for by a vertical adjustment of the former through the screw 64-. Variations in solo thickness may be compensated for by the screw 6 alone. A change in the path of movement of the former, due to operation on Economy-Gem insoles having a channel inside the lip, is readily taken care of by properly related variations in the position of the former through the adjustments described The adjustable screw 56 may be secured attherear' side of employed in this connection but its principalfunction is to receive the thrust transmitted to the lever 35 by the cam lever 37.

Immediately after the initial engagement of the work by the inside former the sole is engaged upon the outside of the lip and feather by a feeding former or foot adapted to engage with and press the reenforcing fabric against the feather and an auxiliary foot or former 71 adapted to engage with and press the reenforcing fab ricagainst the top ofthe lip, as is usual in. machines of this class. The feeding former 70 is secured upon the'lower end of a vertical slide 75 which is provided with a ram roll 76' on the upper end received with in a cam path 78 formed in the hub of a hand Wheel 79. Thls mechanism serves to impart the proper movements to the feeding former toward and from the Work. The auxiliary former71 is adjustably secured to the front face of the former 70 through a slot 82 formed in the member 71, which receives a clamping bolt 83 threaded in the member 75,- as shown in Fig- 2. *In order to impart the lateral feeding movements to the former at predetermined intervals the slide 7 5 is received in a second horizonta] slide 85 supported for movement in ways formed in the machine frame. The proper movements are imparted to this horizontal slide 85 by. a bell crank 86 fulcrumed upon a stationary stud 87 and having a cam roll 88 upon the upperend which is received in a cam path 89 formed in one face of the cam disc 42. The lower arm of the lever 86 is provided with afslotted lug 90 which receives a slide block 91 pivotally the projecting end 92 of the slide 85'. This construction serves to depress the feeding formei into engagement with the work upon the table 10, to move the former laterally in-synchronism with the feeding movements of the table and to thereafter elevate and return. theformer to initial position'out of engagement with the work.

As heretofore stated, the inside former ismoved laterally with the feeding form: erand this is conveniently accomplished in the present construction by connecting the inside former with the slide which carries the feeding former.- To this end, as shown clearly in Figures 1 and 2 of the drawings, the lever 82 is provided with a slotted hub which is engaged by a pro jecting tongue 101 formed upon a right angled bracket 102 clamped to the' side of theslide 75 through a member 103. .In order to permit the requisite lateralmove ments of the inside former and supporting' lever 32 the latter is freely movable upon studs and 105 secured, respectively, to the: arm 35 and link 44;, as shown in Fig. 2. The cam path 40 is designed with a double throw to impart two tucking movements to the inside former respectively before and after the feeding movement, the first tucking movement serving to measure out the requisite amount of reenforcing fabric on the inside of the lip and the second movement serving to bring the fabric finally into place; The inside former there after retains its position against the lip durng the action of the outside former, presently to be explained, providing an anvil over which the lip is bent inward. The inside former at the end of the feed has been moved to a position opposite the out side former, and the feeding former occupies a position behind the outside former, being received in a recess in the back thereof. WVith this construction the inside former is caused to engage twice withv the same portion of the reenforcing fabric and effectually trick the fabric into the junction of the lip and body of the insole. y

In order to'c'omplete, the forming of the reenforcingfabric about the outside ofthe rib initiated by the feeding former and to cause the reenfoi'ced rib to stand at the proper angle relative to the sole, a member 95 is employed having the combined functions of an outside former and lip bending hammer. This tool, asshown in the drawings, is provided-with an inclined face, preferably concavely curved, adapted to engage the outside of the reenforced lip and bend the lip inward over the inside former 80, and a horizontal face to press the fabric on the feather, the angle between these faces serving to set the fabric into the outside angle. The outside former 95 is formed upon the lower end of a vertical slide having rack teeth 111 formed upon one side which areengaged by a toothed segment 113 formed upon an oscillatory arm 11% secured to one end of a shaft 115. The opposite end of the shaft 115 carries a second arm 116 which is connected to the feed cam lever 18 through a link 120. as shown in Fig. In as muchas the rotation of the feed table 10*takes place in the direction of the arrow shown in Fig. 1, the feeding movement takes place when the upper end of the lever 18 is moved tothe right and the, lower end of the lever tothe left in Fig. 3. This feeding movementof the lever 18, through the hereinbefore de scribed connections, serves to elevate the outside former 95, and the return of the lever to initial position, preliminary to the next succeeding movement, returns the out side former 95 into operative position. Thus it will be seen that the movement of the outside former into engagement with the insole takes place while the sole is held in a stationary position upon the work table. 7

Provision is made for varying the limits of movement of the outside former to compensate for varying thickness in the stock to be operated upon and to provide a harder or lighter blow as may be desired. Accordingly the arm 11G (Figs. 1 and 3) is provided with a slot 122 which receives a belt 123 secured in the end of the link and clamped to the arm by a nut 124. A screw 126 threaded through the upper end of the slot 122 and engaging at its lower end with the bolt 123 serves to vary the position of the link 120 relative to the arm as desired, when the nut 124 is loosened.

The cam disc 42 and hand wheel 79 are mounted upon a drive shaft journaled in the upper portion of. the machine frame 12 and having a drive pulley 131 mounted upon one end. The cam disc 42 with the several cam paths formed therein and the cam formed on the hub of the hand wheel 79 serves through suitable connections to impart all of the operative movements to the work table and the various forming tools cooperating therewith.

In the present construction the reenforcing fabric is severed along a line which causes the fabric to lie within the edge of the insole when finally applied thereto. This is conveniently accomplished by trimming the fabric, before it has been laid upon the outer side of the lip and feather, at a distance from the edge of the sole so measured as to cause the fabric to extend only part way across the feather when finally applied, as shown in Fig. 4. By thus trimming the fabric inside of the sole edge and before it is laid upon the feather. all liability of the fabric being exposed after the insole has been incorporated in a boot or shoe is avoided. To this end an under shear plate or cutting blade 135. is supported behind the under-former 25 and when the sole is initially placed upon the work table the marginal portion of the fabric extends outwardly over this plate and rests upon it and a freely rotatable supporting wheel 134 which serves to hold the fabric in a plane above and parallel to the plane of the feather. The wheel 134 is spaced from the blade 135 to permit the severance of the fabric just in the rear of the blade. An oil pad 133 keeps the supporting wheel wiped clean of cement. The shear plate is provided with a curved edge 136 which cooperates with the edge of a rotary knife in the form of a cutting disc 137 to cleanly sever the fabric. The cutting disc 137 is normally supported in the position shown in Fig. 1 above the fabric and is arranged to trim the fabric upon the downward movement of the feeding foot 70. .To this end the cutting disc is mounted upon the inner end of a shaft 140 journaled in a head 141 which is secured to the vertical. slide 75 carrying the feeding foot.

With this construction it will be noted that the rotary cutting disc 137 moves in unison with the feeding foot 70, the downward movement of the foot serving to impart a chopping cutting movement to the disc which thereafter moves laterally with the foot during the feeding movement, thus serving to avoid interference with the work during the feeding movement. The cutting blade 135 is also moved laterally during the feeding movement through a connection with the rotating disc. To this end the cutting blade 135 is secured to one end of a shaft 143 supported in a stationary bearing 144. The opposite end of the shaft 143 has an arm 145 secured thereto and provided with a forked upper end 146 which is received within an annular groove 147 formed in a collar 148 secured to the shaft 140. /Vith this construction it will be observed that the cutting of the fabric takes place solely during the downward movement of the feeding foot and while the work is stationary, and during the feeding movement the cutters move with the work, after which the rotary cutter is elevated out of the work and the two members are returned with the feeding foot. It will be noted from an inspection of Fig. 3 that the non-rotatable blade 135 is provided with deflector 150 which serves to direct the severed portions of the fabric out of the machine, more especially during the return movement of the blade into position for a an upstanding 7 new cut. The upstanding portion 150 of the under cutting blade also acts as a guard or abutment for the disc 137 as it reciprocates in the line of feed. The disc 137 is continuously rotated during the operation of the machine, in order to facilitate the cutting action, through a drive shaft journaled in fixed bearings 156 and connected with the cutter shaft 14.0 through a sliding shaft 157 splined within the drive shaft 155 and a short link 158 which, as shown in Fig. 5, connects crank-pins 15$) and 160 secured, respectively, to the shafts 157 and 140. With this construction the shaft 140 is rotated by the shaft 155 and at the same time has provision for endwise and transverse movements relative thereto. An accurate cutting relation is maintained between the blade 135 and the cutting disc 137 by an adjustment of the arm 145 upon the shaft 143, the. adjustable connections shown in Fig. 1 affording provision for all necessary adjustment. The trimming of the fabric is controlled by engagement of the under blade 135 with the edge of the sole and in order topermit the two cutters to yield bodily for variations in the width of feather, a coiled spring is received within the shaft 155 behind the sliding shaft 157 and serves to yieldingly press the under blade against the edge of the sole, the

Ill)

bearings 141 and 144i affording provision all) for the necessary movements of the two shafts, as 1nd1cated in Fig. 1. The spring 165 is engaged at itseuter end by a stud 167 which may be adjusted lengthwise in the shaft to vary the force of the spring as desired. The rotation of the shaft is, se-

cured by a grooved upon its outer end.

When the insole'to be reenforced is initially presented to the machine the insole is located upon the work table with the outer margin of the fabric projecting over the under-former 25 and cutting blade 135, the lip being so located as to be engaged on its respective sides by the inside and feeding formers and on its outer side by the lip bending outside former. When the operation is started the lip is pressed against the under-former which thereafter gages the U'RDSVGTSQ position of the sole. The inside former then advances in a direction to tuck the fabric into the junction of the lip and the body of the insole, drawing the fabric frclm the outside of the lip over the underformer and cutting blade. This initial movement of the inside former serves to IIIQQSUI'QOlf a sufficient.amount of fabric to coverthe inside of the lip. Thereafter the pulley 168 mounted feeding foot 70 is advanced into engage-- ment with the reenforcing fabric and presses the fabric against the outside of the the feather so that the fabricis'b'eaded over and formed approximately to the shape of the .lip. After the feeding i'n'ovement has lip and been completed the inside former is again advanced to finally tuck the fabric into place and form the fabric at the inside angle of the lip and thereafter the outside former 95 is advanced to engage with the ouside of the lip and the feather to complete the forming the fabric upon the lip and bend the lip into an inclined position relative to the body of the insole. During the downward move ment of the feeding foot the trimming knives sever the fabric above the sole and along a line predetermined to cause the fab ric to lie just within the edge of the sole when finally tucked about the lip and pressedwinto contact with the feather.

While it is preferred to employ the specific construction and arrangement of. parts shown and described, it will be understood that this construction and arrangement is not essential except so far as speclfied 1n the claims, and maybe changed or modified tures of the invention.
