MACHINE I'OR LAYING THE SOLES OF BOOTS AN'D SHOES.

Application led August 3, 1917. Serial No. 184,347.

To all whom it may cof/wem:

Be it known that I, LOUIS A. CAsoRAIN, a citizen of the United States, residin at Beverly, in the county of Essex and tate of Massachusetts, have invented certain Improvements in Machines for Laying the Soles of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a speclcation, like reference characters on thedrawings indicating like parts in the several figures.

This invention relates `to machines for use in the manufacture of boots and shoes and more particularly to machines for use in laying the soles of boots and shoes. The general Object of the invention is to provide an improved sole laying machine by the use of which soles may uniformly be lald. properly and quickly, which will produce work superior to that obtainable heretofore, and which will materially reduce the cost of so-le laying operations. The invention is illustrated as embodied in a machine especially designed for laying rubber soles on shoes of the type in the manufacture of which the rubber soles are laid While in an unvulcanized or green condition and are subsequently permanently attached by vulcanization, each of the soles being usually cut initially to final size and provided with a beveled edge for the purpose of enabling the margin of the sole to be forced into adhesion to the sides of the upper adjacent to the shoe bottom.

Heretofore, so far as is known, such soles have been uniformly laid by hand, the customary method of laying an unvulcanized rubber sole consisting in positioning a sole upon a lasted shoe bottom and then conforming the sole to the contour of the shoe bottom andforcing its marginal portion into adhesion to the sides of the shoe adjacent to its bottom by the use of a relatively heavy hand rollerwhich the operator worked back and forth over the sole until the entire surface was roller.

This method of laying rubber soles not only exceedingly laborious and slow but, even with the exercise of the greatest possible skill on the part of the workman, it is extremely difficult, if not impossible, for example, to treat all portions of the sole with suiiicient uniformity to prevent the formation of air pockets which later cause defective vulcanization of the shoe. In practice it has been the common experience that a relatively large n'umber of shoes defective in this and other ways have been produced which'necessarily had to be disposed of at a serious loss to the manufacturers.

A particular object of the present inventlon is to provide a sole laying machine especially adapted for laying unvulcanized rubber soles, by the use of which such soles may be laid with precision and uniformity and which shall have the greatest possible output capacity consistent with satisfactory work. It is to be understood, however, that, while the invention is herein described with relation particularly to 'its applicability to use in laying unvulcanized rubber soles, the

invention is not intended to be limited thereby since it is appreciated that the invention as a Whole or various features thereof may have other and different uses.

lVith these and other objects in view and in accordance with important features of the invention, the illustrated machine comprises a novel organization of means for holding a shoe against pressure applied to the bottom of the shoe and means' for applying sole laying pressure to the shoe constructed and arranged to be rendered effective to apply pressure to the bottom of the shoe and to the sides of the shoe adjacent to the shoe bottom or to the edges of the shoe sole upon relative movement of the pressure applying means and the shoe holding means. In the illustrated embodiment of the invention, the pressure applying movement is effected by bodily movement of translation of a carrier for the pressure applying means relatively to the shoe supporting means.

The machine herein shown is especiallydesigned to force the marginal portion of a shoe sole into adhesion to the sides of the sh`fe 'adjacent to the shoe bottom while the sh ebottom is under sole laying pressure. Af' further important feature of the invention consists in a construction and arrangement of the pressure applying means such that the pressure applied to the sides of the shoe adjacent to the shoe bottom is directed substantially perpendicularly to the sides of the shoe without any substantial component of force in the direction of the height of the shoe, thus avoiding frictional drag upon the sides of the shoe. Practical experience has demonstrated that by the application of pressure in this manner, either to the sides of a shoe or to the upstanding marginal edges of the shoe sole, an unvulcanized or green rubber sole can be readily and expeditiously conformed to the shoe without producing any objectionable distortion of the sole such as would impair the wearing qualities of the shoe and also be detrimental to the appearance of the shoe. Moreover, such application of sole laying pressure, without impairing the usefulness of the organization for treatment of shoes of other types, is particularly well adapted for forcing the sole margin and the "foxing which extends along the sides of rubber soled shoes of certain types into proper adhesion, thus rendering separate hand treatment of the foxing unnecessary, and at the same time properly overlapping the marginal edge of the rubber sole on the sides of the upper adjacent to the shoe bottom.

Other noteworthy features of the invention reside in the construction and arrangement of the pressure applying means. As shown, the pressure applying means comprises a resilient and self-conforming mold provided with a shoe bottom pressing surface approximately complemental to the shape of a shoe sole and provided with resilient side walls adapted to be converged into pressure applying relation to the shoe.

In accordance with another feature of the invention, the illustrated machine is organized to receive and position initially a shoe sole and to permit a lasted shoe to be placed in the mold with its bottom face'laid upon the sole and properly positioned relatively to the sole and to the pressure applying means without any preliminary location of the sole on the shoe bottom or temporary attachment thereto, thus necessitating a prior manual operation. At the same time, the pressure applying means may be used, if desired, to operate upon a shoe on which the sole has previously been positioned and to which it has been preliminarily attached;

To enable the operator to see what he is doing when assembling the sole and shoe, the jack employed for holding the shoe is automatically held in a laterally displaced position during such assembly but is shifted to holding position above the pad before the machine operates to effect the laying pressure, which operation of the machine occurs while the sole and shoe remain in the positions of first assemblyon the pad.

Further features of the invention consist inthe provision of abody of fluid interposed between a fluid container and the pressure applying means. As shown, the construction is such that the body of fluid is of constant volume, relative movement of the pressure 1applying means and the shoe holding means causing the exible pressure applying means to apply pressure to the bottom of the shoe by pressure exerted through the fluid and to apply pressure'to the sides of the shoe adjacent to the bottom through bodily movement or displacement of the fluid.

Still other features of the invention consist in novel auxiliary pressure applying means provided especially to facilitate the operation of the machine upon shoes of relatively small sizes. y

Other objects and features of the invention Will be apparent from the following description when considered in connection with the accompanying drawings and the invention will be set forth in the appended claims. y

The illustrated machine is provided with twin mechanisms one of which is adapted to lay an unvulcanized rubber sole upon a right shoe and the other mechanism to lay a sole upon a left shoe. Both. sole laying mechanisms being substantially identical, only one mechanism will be described in detail, the same reference characters being used to designate similar parts of both mechanisms.

As shown, each solelaying mechanism comprises an upright frame 2 having an overhanging head portion on which is mounted a shoe support or jack for holding a shoe against pressure applied to the bottom of the shoe. This jack comprises a hollow arm 4 pivotally mounted at its upper end upon a shaft 6 in the head of the frame 2 and receiving a rod 8 the projecting lower end of which carries a cross arm 10 extending lon-- gitudinally of the machine and having a toe erative position away from the operator, as

indicated in full lines in Fig. 1. The jack is moved into the o erative position indicated by dotted lines, ig. 1, to hold the ,shoel against sole laying pressure, by-

means of a treadle 24 which is fulcrumed 'pn a shaft 26 in the frame and has its rear end connected at 27 by a rod 28 to one end 'of a lever 30 fulcrumed on a shaft 32 in the head of the frame. The forward end of the lever 30 is arranged to engage a cam surface 34 provided on the back of the arm 4 directly below the shaft 6 to cause the arm 4 tobe swung forward into a substantially vertical position. A bolt 36 threaded through a lug 38 formed on the arm 4 serves as an adjustment to determine the position of the jack to hold the shoe during the application of sole laying pressure. In laying unvulcanized rubber soles upon the lasted bottom of a shoe, it is extremely important that a uniform sole laying pressure be applied to the shoe to conform the sole to the contour of the shoe bottom and to prevent air pockets from being formed between the shoe bottom andthe sole which would later cause defective vulcanization of the shoe. Also it is essential in providing 'a satisfactory machine for laying unvulcanized soles to cause the sole laying pressure vto be directed substantially perpendicularly to the tread surface of the sole, that is, substanally perpendicular to the bottom of the sole and to the adjacent side faces of the shoe, since such soles, ordinarily extend over on to the side faces of the shoe adjacent tothe bottom and, being more or less plastic, are easily distorted, thus detracting from the neat appearance of the shoe and preventing proper attachment of the sole to the shoe. t

In the illustrated embodiment of the invention, the means for applying sole laying pressure for laying the sole on the shoe, which means 'are hereinafter referred to as the pressure applying pad, is so formed and arranged as to apply a substantially perpendicular sole laying pressure to the bottom ofI the shoe and to the sides of the shoe adjacent to the shoe bottom when bodily movement of translation of a carrier for the pressure applying pad relatively to the jack is e'ected. As herein shown, the pressure applying pad comprises a metal Afiuid container or chamber 40 of a suitable shape to receive a shoe and having an outwardly projecting iange 42 formed along its upper edge. This chamber is sealed by a sole receiving ad or mold-44 which is dis.- posed across t e top of the container and has its marginal edges clamped between the ange 42 of the container and a suitably walls 52v of the chine, this me ium comprises -a body of shaped rim 46 which is secured to the flange. 42 y screws 48 so located as not to pass through the margin of the pad or mold 44. Ahead formed on the under surface of the A rim 46 and (3o-operating with a similar bead` on the flange 42 Iserves further to secure the mold 44 to the container 40. The sole engagingl pad or diaphragm 44 herein shown consists of a resilient -elastic material such as rubber andgit is formed and arranged to constitute'a conformable lshoe and snoe sole receiving mold or matrix of a normal shape to present "a shoe bottom pressin surface 50 approximental to the contour -o the bottom of a shoe and having side walls 52 adapted to be converged into pressure applying relatibn to the side faces ofthe shoe adjacent to the shoe bottom.

For the purpose of causing the mold 44 to be forced into exact conformation with the bottom `and the adjacent side faces of the shoe and to cause a uniform sole laying pressure to be exerted upon the shoe when the pressure applying pad is moved bodily relatively to a shoe held by the jack, the container 40 isrovided with a constant volume of a mobi e or displaceable medium adapted to act upon the bottom 50 and side ad. In the illustrated mafluid, preferably of water, of a sufficient constant volume to cause a'uniform translation of the pressure to be. exerted -upon the shoe engaging walls of the mold 44 to force the mold into uniform sole laying pressure upon the shoe. This application of pressure by the mobile body of- Huid is such as to cause the walls of the mold to exert a substantially1 perpendicular sole laying pressure upon all portions of the bottom and the side faces of the shoe substantially simultaneously, this application of sole layin pressure preventing distortion ofthe so e and also enabling the marginal portion of the sole to be rolled over on to the sides of the shoe with ing which usually extends along the marginal side faces of the shoe the side walls 52 are sloped outwardly from the shoe bottom pressing surface 50 of the mold. These walls 52 are preferably so sloped with respect to theI shoe bottom pressing surface 50 as to enable them to be Converged into pressure applying relation to the shoe after a substantial part of the sole laying pressure has been applied to the bottom of the shoe. IBy reason of this arrangement the walls. 52 of the mold direct a substantially. perpendicular pressure upon the sides of the shoe without any substantial component of force in the direction of the height of the shoe thus eliminating any frictional drag of the walls upon the sides of the shoe during the relative pressure applying movement between the pressure applying pad and the jack. Moreover, the side walls exert the necessary pressure upon the foxing which ordinarily extends along the marginal sides of the shoe to force it into proper adhesion to the upper and thus render a separate hand treatment of the foxing unnecessary.

In the illustrated machine, the pressure applying'movement of the pad is effected by a poweroperated pad carrier 56, the upper end of which is formed to provide a table 58 upon which the 'pad is detachably mounted by means oftap screws 60. AThis carrier is guided for vertical reciprocation by two pairs of links 62, 64, eacl pair being disposed on either side of the carrier 56 and pivoted at their forward ends upon studs 66, 68, respectively of the carrier and at their rear ends on a stud and a shaft 72 respectively on the frame 2. The bodily vertical movement of translation of the carrier 56 to establish a pressure applying relation between` the pad and the shoe is effected by an eccentric cam 74 which engages a cam roll 78 provided on the lower end of the carrler. The cam 74 is loosely mounted on shaft 80 and is connected thereto for a predetermined length of time by means of a treadle-controlled'one revolution clutch connection to the shaft 80 of the machine. The shaft 80 is continuously driven by a fast pulley 84 on the main or driving shaft 72 which transmits power through the sprocket 86 and a chain belt 88 to a much larger sprocket 90 fast on the shaft 80. Therefore the speed of rotation of the lshaft 80 is determined by that of the shaft 72 so that each complete rotation of the shaft 80 is effected during a period of time controlled by that of the driving mechanism. The illustrated one revolution clutch connection between the eccentric cam 74 and the cam shaft 80l includes a disk clutch member 92 which is fast on the shaft 80 and located beside the cam 74, the disk being provided with two longitudinally extending slots 94. Pivotally mounted on one side of the eccentric cam 74 and at substantlally the highest point in the cam throw is a spring actuated dog 96 which is adapted to engage either of the slots 94 in the disk 92, to cause rotation ofthe eccentric with the disk. rIhe dog 96 had a laterally projecting lug 97 (Fig. 3) and is normally held out of engagement with the slots 94 by an arm 9 8 fulcrumed on the shaft 26 and having its upper end provided with an inclined rib 100 indicated by dotted lines in Fig. 1, which rib is adapted to engage the lug 97 of the dog 96 to maintain it inoperative. This arm 98 mames A spring 112 connected at one end to the arm 106 of the treadle lever 24 and at its other end to a stationary arm 114 on the frame 2 maintains the treadle in a raised or inoperative position.

It will thus be seen that the first part of the depression of the treadle 24 causes the shoe holding means or jack 8 to be moved `into operative or shoe holding position, due

to the connecting rod 28 and the lever 30, and further depression of the treadle effects a single rotation of the eccentric cam 74 to cause the pawl 102 to move the arm 98 out of engagement with the dog 96 and allow it to engage one of the slots 94, thereby connecting the eccentric cam 74 to the continuously rotating hub 92 to raise and lower the sole laying 4pad once relatively to the shoe held by the jack.

It has been found that in laying unvulcanized rubber soles upon a shoe bottom it is not necessary to subject the sole to a sole laying pressure for any length of time, but, on the contrary, to cause a substantially instantaneous sole laying pressure to be applied to the shoe since the sole is of a character which is readily conformable to the shoe bottom and will adhere to the shoe as soon as brought in contact with the shoe bottom. On the other hand, if the shoe is subjected to a sole laying pressure for any great length of time, the sole is liable to be distorted.

For this reason such a structure as just described is employed. To `illustrate this, assume that the driving mechanism is so timed thatthe shaft 80 is rotating at 30 R. P. M., then the period of time during which sole laying pressure is exerted will be approximately one second. This is ordinarily suicient and the operator can not accidentally vary it. Hence'uniformity in the treatment of all the soles to be laid can be reliably secured because, like machinery in general, whatever is employed to actuate the main shaft 72, will im art a known and constant speed to said sha t. ,f

The illustrated sole laying machine ,/may be used in the manner usually employed in laying soles by machinery, that is, first preliminarily positioning the shoev sole on the lasted shoe bottom by hand and then presenting the assembled shoe to the machine for the sole laying operation. In the contemplated use of the said 'illustrated machine, ho Wever, the' lasted shoe and the sole Cal which is to be applied to the shoe are presented lto the machine without any prelimina positioning and temporary attachment ofi-lie sole to the shoe, this being possible by reason of the novel pressure applying pad of this invention. In accordance with this use of the machine, the unvulcanized sole the upper surface of which is preferably coated with a suitable cement is first placed in the sole shaped mold 44 or shoe sole receiving pocket constituting` the pad and then the lasted shoe placed in the mold with the lasted shoe bottom engaging the upper surface of the sole. During this placing of the sole and the lasted shoe on the pad, the jack occupies a laterall displaced position such as indicated by fu l lines in Fig. 1, vthe soleand-shoe-supporting surface of the pad being therefore exposed to enable the operator to watch his work and effect correct assembly of the parts which is important when said parts carry an adhesive. Then, Without movement of the shoe and sole from their assembled positions on the pad. the jack swings over to the position indicated by dotted lines in Fig. 1 and the laying'pressure begins. The mold thus receives the lasted shoe and the sole in a predetermined relation to thejack, and the walls of the matrix or mold relatively locate the shoe and the sole with respect to each other for the application of sole laying pressure, thus eliminating the initial hand operation heretofore necessary.

In the event'that the shoe to be operated on is such as not to be accurately locatedwith respect to the shoe bottom pressing surface and the pressure applying walls of the pad to secure the best results three shoe positioning `devices or gages are provided. These devices are preferably locatedat the end of the shoe, the toe portion and the shank of the shoe respectively, the location of the devices relatively 'to a shoe corresponding approximately to the points on a shoe which have the least variatlons over a given range of sizes of shoes. Each of these gages comprises a narrow blade 116 which' is adjustably secured by means of a slot and screw connection 117 to the forward e'nd of one arm of a bracket 118 which is pivotally mounted on a pin 119 held in depending lugs formed on the rim 46. A torsion spring 120 is connected to the bracket 118 and the frame so that in the normal inoperative position of the locating devices they are held in retracted position withdrawn from the mold 80 as shown in Fig. 3, a stop'arm'121 on the bracket engaging the flange 42 of the container. The gages are projected into operative position in the mold 44 by' means of a foot treadle 122. In the operative shoe locatin position of the gages, as sho'wn in dotted ines in Fig. 1, the lower ends of the blades 116 are located in the angle between in a uideway formed in the under side of the ta le 58 of the' carrier 56. The rod 124 carries a cross bar 126 upon which are mounted three brackets 128 each containing a spring pressed plunger 130 for engaging a tail piece formed on each of the corres onding brackets 118. Upon'depression of t e foot treadle 122 the rod 124 carrying the plungers 130 is raised to tip the brackets 118 forwardly and project the blades 116 into s vertical position in the mold 44 where they serve as guldes for the shoe to locate it propt is contemplated that two molds for laying the soles on right shoes and two molds for laying the soles on leftshoes will take care of the range of sizes of shoes to be operated upon. As herein illustrated, the pressure applying pad is adapted to receive the largest shoe of alpredetermined range of sizes of shoes and in order to enable the soles of shoes of smaller sizes to be laid by the pad to the best advantage, an auxiliary pressure applying heel pad is provided. This auxiliary pad consists of a heel shaped mat 132 of resilient rubber material of substantially uniform thickness and having an upstanding wall 134 extending around theside and rear edges of the mat, as shown in Fig. 5. Owing to the fact that rubber soles are of substantially greater thickness at the heel than at the shank and forepart of the sole, a. flat metal plate 136 is preferably embedded in the mat or heel pad. This plate serves to reinforce the iioor of the pad 132 and causes it to exert a substantially perpendicular and fiat pressure to the heel end of the sole Without distorting the sole. The side walls 134 confine the edge of the heel end of the sole and operate lin a manner similar to the side Walls 52 of the mold to force the margin of the Sole over on to the sides of the shoeas the relative displacement of the liquid in the container causes the mold to be forced into conformation with the bottom and sides of the shoe. For the purpose of positioning the auxiliary pad 132 in the mold according to the size of the shoe to be operated upon and also to assist in maintaining shoes of smaller sizes nproperly positioned in the mold, the auxiliary pad is provided with two pins 138 which may conveniently be formed on the metal plate 136 and project from the under side of the mat. These pins are received in suitable holes 140 provided in the Hoor 50 ofv the mold 44. These holes are formed in two staggered rows, as shown in Fig. 5 which are 4slightly offset laterally at an angle to the median line of the shoe corresponding to the locatio-n in which the heel portions of shoes of .a range of sizes will fall when properly positioned in the mold.

In the use of the illustrated machine the operator first places in the mold a sole which is to be laid, and then depresses the treadle 122 to cause the gages 116 to be projected into the mold. He then places a lasted shoe upon the sole with the side and one end of the shoe in contact with the gages 116, the purpose of the gages being to facilitate the p-roper location of the shoe upon the sole. Upon release of the treadle 122, the gages 116 are retracted from the mold by the springs 120. By locating the sole on the shoe through presentation of the shoe to the sole laying machine the necessityyof any preliminary location of the sole on the shoe by hand is eliminated. Moreover, the greater accuracy by whichthis step is performed is `of co-nsiderable importance since any misplaced or otherwise improperly located sole when rolled over on to the sides of the shoe is very noticeab-le and detrimental to the neat appearance of the shoe. The operator next depresses the foot treadle 24. The first part of the movement of this treadle causes, through the rod 28 and lever 30,- the jack 4 to be moved forward about its pivot 6 into position for the toe post 12 and the heel block 14 to engage their respective portions of the last. Further depression of the treadle causes the arm 106 of the treadle through the latch 102 to move the arm 98 out of engagement with the spring actuated dog 96 on the eccentric and allow it to engage one of the slots 94 in the rotating disk 92, whereupon the eccentric is actuated to force the carrier 56 carrying the pressure applying pad upwardly. The.A shoe in the mold 44 immediately engages toe post 12 and heel member 14 of the jack and is prevented from further upward movement, while the resilient mold 44 yields and allows the carrier and pad to continue its upward movement, This relative movement between the pressure applying pad and the shoe causes the surface 50 of the resilient mold 44 to conform to the contour of the botto-m face of the shoe and at the same timethe displacement of the water in the' container caused by the relative movement acts to exert a substantially uniform sole laying pressure upon the bottom of the shoe. After a substantial vpart of the movement of approach between thev pressure applying -pad and the shoe'has been effected, sufiicient water is displaced to cause the side walls 52 of thefmold 44 to be converged or forced into engagement with the sides of the shoe, as illustrated in Fig. 2 of the draw, ings, to apply a sole laying pressure to the sides of the shoe; This converging movemarges are, at all times, confined by the walls 52 of the mold. Owing to the equalizing character of the medium acting upon the mold 44 to conform it to the exact conformation of the bottom and sides of the shoe, a substantiall perpendicular sole laying pressure is app ied to all portions of the sole. By rea- 'son of the fact that the side walls 52 of the mold are not moved into engagement with the side faces of the shoe until a substantial part of the relative vertical movement between the pad 44 and the shoe is effected a substantially perpendicular pressure is applied to the side face of the shoe without any substantial component of force in the direction of the height of the shoe whereby any friction drag of the side walls upon the shoe is avoided. If the shoe being operated upon is provided with a foxing, as are a great many of the yulcanized shoes, this applica tion of a substantial perpendicular pressure is of extreme importance since otherwise the foxing of the shoe would be injured. Also the side pressure serves to force the foxing into adhesion with the upper whereby a separate hand rolling of the foxing is not necessary. A further advantage gained by causing vthe application of Sole laying pressure to be applied to the bottom of the shoe in advance of the application of pressure u on the sides of the shoe to roll the marginal edge of thev sole, is that the possibility of air being trapped between the bottom of the shoe and the sole is. reduced to a minimum and consequently amuch smaller percentage of seconds or defectively vulcanized shoes are produced. Any excess pressure which the shoe might be subject to, due to the varying heights of lasts of different sizes, is taken care of by the spring 28 provided in the jack 8. All of the above described opera-tions are effected quickly, during the upward movement of the pad carrier. During the last half of the single'rotation o-f the eccentric cam 7 4 the carrier 56 and the pressure applying pad are lowered and the jack returns to its inoperative position indicated by dotted lines in Fig. 1, due to the action of spring'22.` No second rotation ofthe cam can occur unless thevtreadle 24 is released Vand again operated because, when the cam "74 andthe dog 96 -which is pivotally carried thereby, are approaching the end of the revolution, the lug 97 of the Ydog engages the lower inclined face of the rib 100 so that, during the rest `of said revolution, the dog 96 is automatically disengaged from the rotating disk 92. lVhelrit is desired to lay the soles of somew-hat smaller sizes than the mold was made to accommmlate. the auxiliary pad 13:2 is used. ln the use ot' this pad, it is positioned on the floor of the mold by means of the pins 138 in accordance with size of' the shoe to be operated upon and the sole and shoe. then placed in the mold in the manner above described. the heel end of the shoe fitting the auxiliary pad so that in the operation of the machine. the pad operates upon the shoe in substantially the same man3 ner as the pad ll. the side walls 134 of the pad acting to confine the edges of the heel portion of the sole to prevent distortion of the sole.
