33 Claims.

This invention relates to machines for pressing the bottoms of shoes, and in some aspects more particularly to machines for pressing the bottoms of welt shoes after attachment of the welt but before the outsole is applied to the shoe. The invention is accordingly herein illustrated. and described with special reference to an operation of that character, although it will be recognized that in Various aspects it is not thus limited in its applicability.

In the manufacture of welt shoes it is sometimes the practice, after the Welt-sewing and inseam-trimming operations, to apply compacting pressure to the inseam materials, i. e., the parts of the welt, upper and insole that are directly connected together by the inseam stitches, preparatory to the laying of the outsole. This permits the outsole to be applied in closer relation to the insole and upper and contributes also in other ways to better results in the manufacture of the shoe. For thus pressing the inseam materials there have been utilized to some extent machines of the same general character as commonly used for leveling outsoles with rolling pressure, characteristic features of which are disclosed, for example, in Letters Patent No. 1,667,761, granted on May 1, 1928, upon an application of E. E. Winkley and H. A. Davenport. In the operation of such a machine the shoepressing roll is moved downwardly into contact with the toe end of the shoe bottom when the latter is under the roll, after which the roll traverses the forepart and shank portions of the shoe bottom with its axis in a substantially horizontal position generally parallel to the shoe bottom. Thereafter the roll operates along the opposite sides of the shoe bottom successively while held in such positions that its axis is inclined laterally of the shoe.

An object of the present invention is to pro-vide improved means for pressing shoe inseam materials whereby better results may be obtained than by the use, for example, of a machine operating as above described. For the purposes in View the machine herein shown is provided with a pair of pressing rolls arranged to operate respectively at the opposite sides of the shoe bottom, the rolls being relatively movable heightwise of the shoe so as to assume positions determined by the contour of the shoe bottom and thus to apply adequate pressures tothe inseam materials at the opposite sides of the shoe bot- A tom while operating along both sides simultaneously, To permit such relative movements of the rolls they are carried, in the construction shown, by arms which are mounted for swinging movements heightwise of the shoe, and the rolls are pressed down on the shoe bottom by different springs associated respectively with the different arms and each adjustable as to stress independently of the other.

ln operating upon the inseam materials it is desirable to press them not only heightwise of the shoe, but also in directions inwardly from the edge of the shoe bottom, in order to improve such conditions as may have resulted from outward pull on the lip of the insole in the earlier lasting and welt-sewing operations; and in another aspect the present invention provides improved means for accomplishing this result. For the purpose in view the construction herein shown is such that the rolls as they rst traverse the vshoe bottom act on the inseam materials at the end of the toe and along the sides of the shoe bottom rearwardly of the toe end with pressures directed both heightwise of the shoe and inwardly from the edge of the shoe bottom. More particularly, as illustrated, the rolls are so arranged as to act on the inseam materials rst at the end of the toe with inwardly directed pressure and to be lifted by the action of the shoe thereon while pressing the materials heightwise of the shoe, after which the rolls act on the materials along the sides of the shoe bottom at the rear of the toe end with pressures directed both heightwise of the shoe and inwardly from the edge of the shoe bottom. To render the rolls effective in this manner along the sides of the shoe bottom, they are so formed as to increase progressively in diameter toward their outer ends and are so mounted as to permit them to be wedged apart by the action of the shoe thereon against the resistance of spring means that constantly urges them inwardly toward each other. To permit such movements of the rolls toward and from each other, their supporting arms, mounted as above described for swinging movements heightwise of the shoe, are also supported for swinging movements relatively to each other widthwise of the shoe; and for better accomplishment o1" the objects in view the construction shown is further such that initially the rolls are positioned in axial alinement with their inner ends in contact with each other for operation on the inseam materials at the end of the toe. By this organization the inseam materials are pressed inwardly in a more satisfactory manner than by machines operating as heretofore, in the manner above described, to

press them first heightwise of the shoe by the action of a single horizontal roll and thereafter to apply more or less inwardly directed pressure by the action of the roll in inclined relation to the shoe bottom.

The above and other features of the invention, including novel means for alining the rolls properly with the shoe lengthwise of the shoe, novel means whereby the rolls may be adjusted properly in relation to the shoe bottom, and various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In the drawings,

Fig. 2 is a plan view on a larger scale of a portion of the structure shown in Fig. 1, with parts broken away;

Fig. 3 is a section on the line III-III of Fig 2;

Fig. 4 is a view similar to Fig. 2 of a portion of the structure there shown, but illustrating the positions of the parts as the rolls begin their operation at the end of the toe;

Fig. 5 is a side elevation of the parts shown in Fig. 4, with one of the rolls omitted and a portion of its supporting arm broken away; and

Fig. 6 is a right-hand side elevation similar to a portion of Fig. 1, but illustrating the use of a saddle between the leveling rolls and the shoe.

Machines of the well-known type illustrated are twin machines, having two sets of operating instrumentalities for operating respectively on shoes in different locations in the machine. Portions of only one of these two sets of instrumentalities are shown in the drawings, since they are substantially alike, and only such parts of that set as it is necessary to refer to for an understanding of the invention will be hereinafter mentioned.

For supporting a shoe in position for the bottom pressing operation machines of the illustrated type are provided with a shoe support or jack comprising a toe post I0 and a heel post I2 which are relatively adjustable for shoes of different lengths. The toe post I6 carries a toe rest I4 for supporting the toe end of the shoe, and pivotally mounted on the heel post I2 is a block I6 which carries a spindle I8 arranged to enter the spindle hole of the last. Through connections including a link 28 the block I6 and its spindle I8 are tipped by a hand lever 22 to jack the last and shoe firmly upon the toe rest I4, as more fully disclosed in Letters Patent No. 1,719,158, granted on July 2, 1929 upon an application of E. E. Winkley and H. A. Davenport.

The jack as a whole is mounted for swinging movements in directions lengthwise of the shoe on a rockshaft 24, and such movements are imparted to the jack by automatic operating means to cause the pressing rolls hereinafter described to traverse the forepart and shank portions of the shoe bottom. This operating means is of substantially the same character as disclosed in Letters Patent No. 1,239,664, granted on September 1l, 1917 upon an application of W. C. Baxter, and includes an operating lever 26 connected by a link 28 to another lever 30 which is pivoted at 32 on the frame of the machine, the lever 38 in the construction herein shown carrying a roll 34 engaged by a path cam 36 carried as heretofore by a cam disk 38 fast on a cam shaft 40. Secured to the cam disk 38 is a worm wheel 42 engaged by a worm 44 on a shaft 46 which is operated through a clutch 48. Associated with the clutch 48 is clutch-controlling mechanism including a shipper rod 50 movable toward the left (Fig. 1) to connect the parts of the clutch and toward the right to disconnect them and stop the machine. Stopping of the machine is effected automatically by a member 52 carried by the worm wheel 42 and arranged to engage a roll 54 carried by a plate 56 which is mounted to swing about a stud 58 and has a nger G8 arranged to engage an arm 62 fast on the rod 5C. When the member 52 thus engages the roll 54 the plate 58 is swung against the resistance of a spring 64 and acts on the arm 62 to move the rod 5D to the right and thus to stop the machine. The starting of the machine is eifected by a treadle, not shown, which rocks the rod 50 and the arm 62 and thus carries the arm out of engagement with the nger 6D, whereupon a spring 66 moves the rod 56 to the left to start the machine. This controlling mechanism is constructed substantially as heretofore in machines of the illustrated type, except that as herein shown there are two diametrically opposite members 52 for stopping the machine at the end of each half revolution of the cam disk 38 for reasons hereinafter explained. In machines of the type referred to the jack is swung initially inward by the operator to a position where it is connected to the jack-operating means by a pin 68, as disclosed in the previously mentioned Letters Patent No. 1,239,664, and just before the machine comes to a stop mechanism controlling this pin is operated by a member 'i8 on the cam disk 38 to disconnect the jack from its operating means. Since there are two members 52 in the machin# herein shown for stopping the machine at th.' end of each half revolution of the cam disk 38, as above explained, there are likewise two members 'i6 for releasing the jack as required substantially at the times when the corresponding members 52 become operative to disconnect the parts of the clutch.

For purposes of this invention there are provided two rolls 'I2 (Fig. 2) arranged to operate respectively at the opposite sides of the shoe bottom, each of these rolls having a pressing face curved widthwise of the shoe and each roll increasing progressively in diameter from its inner end outward. These rolls are rotatably mounted on studs 'I4 which are fastened to arms 'I6 so that the axes of the rolls are at all times in fixed relation to the arms, ball bearings 'I8 being provided between the rolls and the studs, as indicated in Fig. 2. Each roll is held on its stud 14 by a washer 'I9 (Fig. 5) and a screw 80. The arms 'I6 are mounted independently of each other for swinging movements heightwise of the shoe on pins 8| supported on brackets 82, and these brackets are mounted for swinging movements on pins 84 extending heightwise of the shoe and supported by a member 86. The member 88 is a sleeve member fastened on the forward end of a rod 88 which serves as a roll carrier and is mounted to turn in a holder 9U, this holder being provided with trunnions 92 whereby it is mounted for swinging movements in directions heightwise of the shoe. Fastened to the rod 88 within a recess in the holder 98 is a sleeve 84 which by engagement with the holder prevents lengthwise movements of the rod 88. The sleeve 94 is provided with lugs 96 in which are threaded screws 98 arranged to bear at their lower ends on the holder 90. The screws 98, therefore, prevent turning movement of the rod 88 and of the rolls 'I2 about the axis of the rod in the operation of the machine on a shoe, but afford provision for adjustment of the rod and the rolls about this axis.

It willv be evident that the roll-carrying arms 16 may swing with the brackets 82 in directions widthwise of the shoe above the axes of the pins 84. The arms are controlled by a spring (Figs. 2 and 4) which is connected to them at its opposite ends and tends to swing them inwardly toward each other. Initially the inner ends of the rolls '|2 are held in contact with each otler (Fig. 4) by the spring |00, the rolls being then preferably in axial alinement, and against the resistance of the spring |00 the rolls are forced apart more or less by the wedging action of the shoe thereon, especially the action of the wider forepart portion of the shoe, as illustrated in Fig. 2. To avoid danger of damaging a shoe such as might result from sudden lateral and downward swinging of the arms 16 in case the spring |00 should break, there is provided a rod |02 extending through lugs led on the arms and having nuts on its ends to engage the lugs and prevent suoh accidental swinging apart of the arms as to permit the rolls to be forced downward over the sides of the shoe.

In order to aline the rolls 12 properly with the shoe lengthwise of the shoe the brackets 82 are further controlled by a coil spring |00. This spring encircles a rod |03 which extends loosely through openings formed in arms i0 fastened to the upper ends of the brackets 82. The spring |06 presses at one end on a flat plate H2 which is slidingly mounted on the rod |08 and is arranged to engage the flat inner face of the adjacent arm H0, this plate having integral therewith a sleeve I4 extending within the coil spring |06 to assist in guiding the plate in any movement of the latter lengthwise of the rod |00. At its opposite end the spring |06 bears on a washer ||6 which abuts against a nut ||8 on the rod |08. Also threaded on the rod |08 is another nut |20 which serves as an abutment for a flat plate |22 arranged to engage the inner at face of the other arm H0, this plate having a sleeve portion |24 extending therefrom loosely through the opening in the arm H0 to assist in holding the plate against any tipping movement relatively to the rod |08. It will thus be seen that the spring |06 tends by expansion to force the plates ||2 and |22 apart and that these plates by their pressure on the arms ||0 tend to maintain these arms and the brackets 82 to which they are fastened in such positions that the plates are flat against the inner faces of the arms ||0, at which time the arms 16 are in such positions that the rolls 'i2 are in proper initial alinement with the shoe lengthwise of the shoe. When the rolls 72 are forced apart by the wedging action of the shoe thereon the plates H2 and |22 are forced more or less inwardly toward each other against the resistance of the spring |00 by the turning movements of the arms H0, as illustrated in Fig. 2, the plates assuming positions in which they are more or less out of parallelism with the adjacent'faces or" the arms I0. It will be evident, therefore, that these plates and the other parts of the controlling mechanism described permit such lateral swinging movements of the arms '|6, either in opposite directions or in the same direction, that the rolls 'I2 may during the pressing operation assume positions determined by the contour of the shoe, and that they insure return of the rolls to predetermined positions widthwise of the shoe when the shoe leaves the rolls. It will also be evident that the spring assists the spring |00 in forcing the arms it inwardly toward each other.

IIhe provision for swinging movements of the arms 'i5 independently of each other heightwise of the shoe about the axes of the pins 8| as hereinbefore described, permits the rolls '|2 to move relatively to each other heightwise of the shoe under control of the shoe so that the pressure applied to the shoe by either roll is unaffected by the position of the other roll, the axes of the rolls being at all times perpendicular to the directions of such movements of the rolls. Each arm 'l0 is under the influence of a separate spring |26 which tends to swing the arm downwardly and thus presses the roll 'i2 upon the bottom of the shoe. The lower end of each spring |26 is held against displacement by a stud |28 projecting within it, and within the upper end of the spring is a similar stud |30 projecting downwardly from a disk |32 in a depression in which is seated the lower end of a screw |34. This screwis threaded in the arm ||0 and may be turned by a hand wheel |36 to adjust the compression of the spring |26, a lock nut |38 being provided to hold the screw in adjusted position. It will thus be seen that the downward pressure of each roll l2' on the shoe may be varied independently of the pressure of the other roll. To limit downward swinging movement of each arm 76 when no shoe is in contact with the rolls 12, each arm has a downwardly projecting finger |40 in which is threaded a screw |42 arranged to contact with the bracket 82. By adjustments of the screws |42 the initial positions of the two rolls 'l2 heightwise of the shoe may be varied independently of each other.

To assist in holding the rolls 'i2 upon the shoe bottom with adequate downward pressure there is further provided a spring |44 controlling the holder 90 and the rod 88, this spring bearing at its lower end on a lever |136 which is pivoted at |00 to the frame of the machine and is connected by a link |50 to the holder 00. The upper end of this spring bears on a disk |52 engaged by the lower end of a screw |54 which is threaded in a sleeve |58 slidingly movable vertically in a portion of the frame of the machine. Bearing on lugs formed on the sleeve |56 near its upper end is the forked end of a lever |58 pivotally mounted on a pin |00 on the frame, this lever being held stationary in a position adjustably determined by a screw |62 which is threaded in the lever and bears on the frame. By means of a hand wheel 64 fast on the screw |54 the screw may be turned to vary the compression of the spring |44 and thus to vary the amount of pressure of the rolls l?. on the shoe bottom. It will be understood that the spring |40 thus acts equally on both the rolls through the previously-mentioned springs |28, but that the two springs |26 may be adjusted independently of each other as hereinbefore explained to vary the pressures applied by the different respective rolls. Downward swinging movement of thel holder 90 is limited by a screw |00 (Fig. 3) which is threaded in the frame and engages the lower face of the holder. This screw and the two screws l 42 are preferably so adjusted that as the shoe is first swung inwardly by the jack the rolls 'I2 engage the inseam materials initially at the extreme end of the toe with pressure directed inwardly from the edge of the shoe bote tom and are lifted more or less by the pressure of the shoe upon them against the resistance of the springs |26 and |44 so that adequate downward pressure is applied through the springs to the inseam materials from the extreme toe end of the shoe to the rear ends of the inseam during the swinging movements of the jack.

In the operation of the machine, the operator first mounts a shoe on the spindle I8 and by depression of the lever 22 jacks the shoe on the toe rest I4. I-Ie then swings the jack inwardly until it is locked to the jack-operating mechanism by the pin 68, and thereafter actuates the clutch to start the machine in operation. The cam 38 is so shaped as to impart to the jack rst an inward swinging movement such as to cause the rolls 12 to traverse the bottom of the shoe from the end of the toe to the rear ends of the inseam materials, then comparatively short swinging movements first outwardly and then inwardly to cause the rolls to traverse the shank portion of the shoe bottom repeatedly, and thereafter an outward swinging movement to cause the rolls to return to the toe end of the shoe and to leave the shoe, such movements being effected in the course of a half-revolution of the cam disk 38. Since the rolls operate simultaneously at both sides of the shoe bottom, these movements are sufhcient to accomplish the results required, and accordingly the machine is stopped at the end of each half revolution of the cam disk as hereinbefore explained, the jack being released from its operating mechanism by the action of the nger 'l0 on means that controls the locking pin E8. As the rolls rst traverse the shoe bottom they act initially on the inseam materials a at the end of the toe with pressures directed both heightwise of the shoe and inwardly from the edge of the shoe bottom (Figs. 4 and 5) and then act progressively on the inseam materials along the forepart and shank portions of the shoe bottom with pressures also directed both heightwise of the shoe and inwardly. In the course of their operations on the shoe the rolls are forced more or less apart against the resistance of the spring IBG by the wedging action of the shoe thereon, especially the wider forepart portion of the shoe (Figs. 1 and 2), and the inwardly directed pressures of the rolls on the inseam materials along the sides of the shoe bottom are due both to the action of the spring IUD and to the fact that the rolls increase in diameter from their inner ends outward. It will be seen that as the tension of the spring I is increased by outward swinging movement of either roll, the spring tends with such increased tension to swing the other roll in the same direction, i. e., inwardly; and this assists in insuring that both rolls will assume proper positions corresponding to the lateral swing of the right or left last as they traverse the shoe bottom.

Instead of directly engaging the inseam materials, the rolls may, if the condition of the work renders it desirable, act upon the materials through a exible saddle |68 (Fig. 4) This saddle may be made of leather and constructed, for example, as disclosed in Letters Patent No. 1,644,- 971, granted on October 1l, 1927 upon an application of E. E. Winkley and I-I. A. Davenport, and the hand lever 22 may be used to apply the saddle to the shoe instead of tipping the last pin I8, as more fully disclosed in the previously mentioned Letters Patent No. 1,719,158. It will be understood that when the saddle is used the rolls 'l2 act in all respects in the same manner as hereinbefore described except that they apply their pressures to the inseam materials through the saddle instead of by direct engagement with the materials.
