24 Claims.

This invention relates to lasting machines, and is herein illustrated as embodied in a machine for performing side-lasting operations as distinguished from operations on the toe or heel-end portions of shoes, the machine being provided with wiping means which wipes the margin of the upper into lasted position along the forepart beyond the toe portion and also along the shank portion of the shoe. For the sake of simplicity a in its organization and convenience in operation the machine herein shown is so constructed as to act on one side only of each shoe, all shoes being positioned with their toe ends pointing in the same direction relatively to wiping means at one side thereof; and it is contemplated that the other sides of the shoes will be lasted in another machine of the same construction except for such changes as are necessitated by the positioning of the shoes with their toe ends pointing in the opposite direction. It is to be understood, however, that in some of its novel aspects the invention is not limited to an organization of this particular character and that in some aspects also it is not limited to side-lasting 25 machines.

In one of its aspects the invention relates more particularly to the positioning of shoes in proper relation to lasting means which operates thereon. ihe machine herein shown is provided with a device which acts at the forepart of the shoe and last to determine the position of the shoe as a whole lengthwise and laterally by means of pins extending into holes in the bottom of the last, in a manner similar to the disclosure of United 35- States Letters Patent No. 1,674,060, granted on June 19, 1928, upon an application of mine. By

such a device different shoes of the same size and style are positioned invariably in the same predetermined relation to the lasting means, thus insuring uniformly good results in the lasting of the different shoes by lasting or wiping means shaped with particular reference to the portions of the shoes on which the lasting operation is performed. In order that the same lasting or 45 wiping means may be used, without sacrifice of efficiency, in lasting shoes of different sizes or shoes in which there are substantial variations in the character of the upper materials, thus avoiding the necessity, for example, of frequent sub- 50 stitutions of differently shaped wipers, the present invention provides a construction in which a device for determining the position of each shoe with the accuracy above referred to is adjustable in certain respects to vary the relation of 55 the shoe to the lasting means. As herein illustrated, the device above described, which determines the position of the shoe lengthwise and laterally by means of pins extending into holes in the bottom of the forepart of the last, is adjustable about an axis extending heightwise of 6 the shoe and also adjustable in directions lengthwise of the shoe. This makes it practicable in a side-lasting machine to use the same wiper, shaped, as illustrated, to conform substantially to the contour of the bottom of a shoe along its 10 forepart and shank portions, in lasting shoes of at least three different sizes and also shoes of different kinds in which, for example, the upper materials vary substantially in thickness. It will be understood that one or the other or both 15 of these adjustments may be required in any given instance in order that the wiper will operate in the best relation to the edge of the shoe bottom and with the proper pressure on different portions of the margin of the upper. The machine herein shown has means whereby the different adjustments may be quickly and conveniently made and whereby the shoe-positioning device is held effectively in adjusted position. The construction shown is further such that the shoe is held in fixed relation to the shoe-positioning device by a member which acts at the top of the forepart thereof and which is so mounted as to partake of the adjusting movements of the device.

The invention further provides a novel organization of mechanism for operating and controlling the side-wiping means in a convenient and effective manner. As illustrated, the shoe is positioned with one side thereof toward the operator at the front of the machine and its other side in position to be operated upon by a' wiper which is operatively movable in a forward direction by a hand lever mounted to swing also in a forward direction about an axis extending 40 lengthwise of the shoe. Such movement of the wiper is effected through wiper-supporting members which are located respectively at different distances from the shoe and are mounted to swing about axes extending lengthwise of the shoe; and as illustrated also a treadle is arranged to act through one of these members to swing the wiper heightwise of the shoe and thus cause it to apply the proper pressure to the margin of the upper.

The above and other features of the invention, including also novel means for supporting the shoe in the lasting operation and various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

Fig. 11 is a sectional view through a portion of the shoe and the wiper, illustrating how the upper may be fastened by tacks.

The machine comprises a frame 2 on which is secured a top plate 4. Supported on this top plate, as hereinafter described, is means for positioning the shoe relatively to a wiper 6, with one side of the shoe facing the operator at the front of the machine and the other side in position for the margin of the upper to be wiped inwardly over the insole by the wiper 6 as the wiper is moved forwardly toward the operator. The wiper, 6, as illustrated in Fig. 10, is of such length as to last the side of the shoe along the forepart beyond the toe-end portion and also along the shank as far as the beginning of the heel-end portion, the wiper being shaped to conform substantially to the contour of the bottom of the shoe lengthwise thereof and its edge being curved in such manner as to conform substantially to the curvature of the edge of the insole along the portions of the A shoe where the wiper operates.

It will be evident that for successful results in the use of a wiper formed as above described the shoe must be positioned accurately in predetermined relation to the wiper. For this purpose the machine herein shown is provided with a plate 8 (Figs. 9 and 10) having fast thereon three pins l5 arranged to extend through holes in the insole into holes provided in bushings 12 inserted in the bottom of the forepart of the last in predetermined relation to the contour of the last. The pins H3 substantially fit the holes in the bushings and thus serve to determine the position of the shoe lengthwise and laterally in accordance with the disclosure of the previously mentioned Letters Patent.- As herein illustrated, however, the position of the shoe heightwise is determined by engagement of the plate 8 with the insole, the construction being such that the lower end faces of the pins II] are spaced somewhat from the lower ends of the holes in the bushings [2. The plate 8 is secured by a screw l4 to an arm I6 and is provided with a rib l8 which enters a corresponding slot 20 in the arm further to determine the position of the plate relatively to the arm. The arm [6 is supported on the upper end of a standard 22 which extends upwardly from and is integral with a plate 24 (Figs. 3 and 6) the standard being arranged to occupy a position opposite the toe end face of the shoe. A stem 25 extends downwardly from the arm 16 into a bore in the standard 22 and is engaged by a set screw 28 (Fig. l) to hold the arm against upward movement, the position of the arm being further determined by a dowel pin 36 extending into a hole in the standard. The standard 22, as hereinafter described, is maintained in a fixed predetermined position during the operation of the machine, and it will accordingly be evident that the plate 8 and its pins ll] determine in every respect the position of the shoe in the lasting operation.

It is contemplated that the same wiper 6 will be used in lasting, for example, shoes of three different sizes which are of the same or substantially the same style, but for wider variations in size and for substantial variations in style differently formed wipers. will preferably be provided. In order that each wiper may operate in the best relation to the shoe for which it is intended, having regard to such small variations in size and also to possible variations in the thickness of the upper materials in different lots of shoes, provision is afforded for adjustment of the standard 22 and its arm is in directions lengthwise of the shoe and also about an axis extending heightwise of the shoe in a location between its toe and heel end portions. For the purpose of such adjustment lengthwise of the shoe the plate 24 on which the standard 22 is formed is slidingly mounted on a plate 32 between upwardly extending flanges 34 formed on the latter, the plate 24 being held in place on the plate 32 by gibs 36. The plate 32 is mounted to swing with the plate 24 and its standard 22 about abushing 38 (Fig. 6) mounted in an opening formed in a boss 40 on the top plate 4, this bushing having a head 42 which overlaps the plate 32 and having a nut 44 threaded on its lower end and engaging the lower end of the boss 40 to hold the plate 32 down on the plate 4. A curved gib 46 fastened on the plate 4 and overlapping one end of the plate 32 further assists in preventing upwardmovement of this plate. For adjusting the plate 24 and its standard 22 lengthwise of the shoe there is provided a lever 48 mounted to swing about a headed stud 50 (Fig. 3) extending downwardly from the top plate 4. This lever has a slot 52 into which extends a pin 54 (Fig. 6) fast in the plate 24, an opening 56 being provided in the plate 32 to permit the required movement of the pin with the plate 24. The lever 48 is connected by a link 58 to one arm of a bell-crank lever 60 mounted to swing about a stud 62 which is supported on a bracket 64 secured by bolts 66 to the lower face of the top plate 4. The other arm of the bell-crank lever 60 is formed as a gear sector 68 engaged by a worm 10 which is keyed on a shaft 12 mounted to turn in front and rear hearings in the bracket 64. Fast on the shaft 12 and engaging the bracket 64 to prevent rearward movement of the shaft is the tubular end of another shaft 14 on which is formed a hand wheel 16 provided with a handle 18 for turning it. Forward movement of the shaft 12 is prevented by the worm member 10 mounted between the front shaft bearing and an enlarged rear end portion of the shaft. It will thus be seen that by rotation of the hand wheel 16 the lever 48 may be swung in one direction or the other to adjust the plate 24 and its standard 22 lengthwise of the shoe. Such an adjustment may be made after a shoe of a given style and size has been mounted on the pins I0, to determine by trial the best position of the shoe and of others of the same style and size relatively to the wiper 6. In order to indicate to the operator at any time how the parts are adjusted in this respect, there is fastened on top of one of the gibs 36 a triangular plate 80 (Fig. 3) provided with a stud 82 on which is pivotally mounted an arm 84, one end of this arm being marked to serve as an indicator with reference to a scale on the plate 80. A pin 86 fast in the plate 24 extends upwardly through a slot 88 in the plate 80 into a slot 90 in the arm 84 to operate the arm.

For swinging the plate 32 and the parts supported thereon about the bushing 38 further to position a shoe of any given style and size in the best relation to its wiper 6, there is provided a lever 92 (Fig. 6) mounted to swing about a stud 94 supported on a bracket 96 which is fastened to the lower face of the top plate 4 in the same manner as the previously mentioned bracket 64. One arm of the lever 92 is forked to engage a pin 98 which is fast in the plate 32 and extends downwardly through an opening I00 in the plate 4, and the other arm of the lever is formed as a gear sector I02 in engagement with a worm I04 keyed on a shaft I06 mounted in bearings in the bracket 96. Fast on one end of the shaft I06 is the tubular end portion of another shaft I08 provided with a hand wheel I I0 arranged to be turned by a handle II 2. The shaft I06 is held against lengthwise movement in the same manner as the shaft 12. It will thus be seen that by rotation of the hand wheel I I0 the plate 32 and the parts thereon may be swung forwardly or rearwardly about the bushing 38. To indicate to the operator how the parts are adjusted in this respect there is fastened on the top of the plate 32 a small plate I I4 which is marked to cooperate with a scale on the top of the gib 46.

After the shoe has been mounted on the pins I0 and against the plate 8 it is supported in the position thus determined by a toe rest II6 which is moved upwardly into engagement with the top face of the toe end of the shoe. This toe rest consists of a rubber roll mounted on a rod II8 which is supported in the bifurcated upper end of a holder I20. The upper end of this holder is connected by a pair of links I22 to the standard 22, these links being pivotally mounted at their right-hand ends on the rod I I8 and at their lefthand ends on a rod I24 extending through the standard. At its lower end the holder I20 is pivotally connected to a lever I26 the left-hand end of which is bifurcated and mounted on a rod I28 extending throughthe standard 22. The lever I26 extends in substantially parallel relation to the links I 22 and at its right-hand end carries a roll I30 which rests on the upper end of a rod I32 vertically movable in the previously mentioned bushing 38. The rod is accordingly located at the axis of swinging movementof the plate 32. Fast on this rod is a block I34 connected by a pair of links I 36 to the bifurcated front end of one arm I38 of a bell-crank lever I40 fast on a shaft I42 which is rotatably mounted at its opposite ends in bearings in the frame. The other arm I44 of this bell-crank lever is connected by a link I46 to an upwardly extending arm I48 of a bell-crank lever I50 mounted to swing about a rod I52 at the base of the machine, this bell-crank lever having a forwardly extending arm I54 which serves as a treadle depressible against the resistance of a spring I56.

In response to depression of the treadle I54, therefore, the rod I32 is raised and imparts upward swinging movement to the lever I26 to raise the toe rest H6 and force it against the shoe. It will be evident that the toe rest partakes of any adjustment of the standard 22 and the arm I6, so that its relation to the pins I0 remains constant, the amount of adjustment lengthwise of the shoe being insufficient to carry the roll I30 from over the rod I32.

To hold the toe rest in shoe-supporting position with the shoe in fixed relation to the plate 8 there is provided a friction lock (Fig. '7) comprising a lever I 58 pivotally mounted on a pin I60 which is supported in a block I62 formed on a plate I64 fastened to the frame at the front of the machine, the lever I58 being provided with an eccentric friction face I66 arranged to engage a flat face on the rod I32. A spring I68 connected to the lever I58 and to an arm I10 fast on the block I60 tends to swing the lever upwardly and thus holds it normally in locking engagement with the rod I32. It will be evident that the lever I58 does not prevent upward movement of the rod I 32 when it is raised by the treadle I54, but acts automatically to prevent any reverse downward movement of the rod. In order to permit such downward movement of the rod to release the shoe after the lasting operation, there is provided a releasing treadle I12 mounted to swing about the rod I52 and connected by a link I14 to the lever I58 through a stud I16 carried by the lever. A slot I18 in the link I14, through which the stud I16 extends, permits such short movements of the lever I58 as occur in the raising of the rod I32 and the locking of the rod. When the treadle I12 is depressed it acts through the link I14 to swing the lever I58 downwardly far enough to release the rod I32. The downward movement of the rod I32 is limited by engagement of a collar I80 fast thereon with the top of the block I62. Depression of the treadle I12 is effected against the resistance of a spring I82 which tends to raise it. To limit the upward movement of the treadle there is provided a link I84 which is pivotally connected at its lower end to the treadle and is provided at its upper end with a slot I86 (Fig. 7) through which extends a stud I88 mounted in the block 162. This stud by engagement with the link at the lower end of the slot limits the upward movement of the treadle I12 and by engagement with the link of the upper end of the slot serves also to limit downward movement of the treadle.

The heel end of the shoe is sup-ported in the lasting operation by a rod I90 the upper end of which carries a rounded button I9! arranged to engage the top of the cone of the last. This rod extends downward loosely through an opening I92 (Fig. 6) in a plate I94 fast on the top frame plate 4 and is connected at its lower end by a universal joint I 96 to a rod I98 mounted for vertical movements in a bearing 200 formed on a bracket 202 (Fig. 2) which is fast on the plate I64. Below the bearing 200 the rod I90 is further guided by a headed bushing 204 (Fig. 8) mounted in an arm 206 on the bracket 202, this bushing having a collar 208 fast on its lower end. The rod I98 is hollow through most of its length and encloses a spring 2I0 the lower end of which rests on a nipple 2I2 supported by a pin 2I4 which. is fast in the collar 208 and extends through slots 2I6 in the opposite sides of the hollow rod I 98. A dowel pin 2I8 extends downwardly from the head of the bushing 204 into a slot 220 in the arm Z06 to prevent the bushing from turning. By means of the spring 2I0 the rod I98 and the shoe-supporting rod I mounted thereon are held normally upraised with the upper end of the rod I90 higher than required for supporting a shoe in the machine, and when the operator presents a shoe in the position determined by the pins- I0 and the plate 8 he engages the top of the cone of the last with the button I9I on the upper end of the rod I99 and depresses the rod against the resistance of the spring 2E0 so that the rod assumes a position determined by the last. The opening I92 in the plate I94 is large enough to permit the rod L90 to be swung to different positions so that it will properly support lasts and shoes of different sizes and styles.

After the rod I90 has been depressed to a position determined by the last, as above described, it is locked against further downward movement so that it is maintained positively in shoe-supporting position. For this purpose there is provided a friction lock comprising a lever. 222 (Fig. 8) pivotally mounted on a pin 224 in the arm 206 and extending inwardly through an opening in the bushing 204. On the inner end of the lever 222 is an eccentric friction face 226 arranged to engage a fiat face on the rod I98 to lock the rod against downward movement. Normally, however, the lever 222 is maintained in a position where it is ineffective to lock the rod. For this purpose there is fast on a rock shaft 228 extending lengthwise of the shoe and mounted in bearings in the frame an arm 230 to which the upper end of a link 232 is pivotally connected, this link carrying a screw 234 adjustably mounted in a lug thereon with its lower end in position to engage a stud 236 extending from the lever 222 through a slot 238 in the link. The rock shaft 228 has fast thereon an upwardly extending hand lever 240, and by means hereinafter described operative forward movement is imparted to the lasting wiper 6 by the turning of the shaft 228 in a counterclockwise direction (Figs. 2 and 8) through forward movement of this hand lever. As the shaft is thus turned the link 232 is raised by the arm 230, and through a spring 242 connecting this arm to the lever 222 the lever is swung upwardly to lock the rod I98 in the manner described. It will be understood that such locking of the rod occurs early in the movement of the wiper 6 before the Wiper begins to act on the shoe. When the wiper is returned to its starting position the arm 230 acts through the link 232 to impart downward movement to the lever 222 and thus to unlock the rod I98 to permit it again to be elevated by the spring 2"] when the shoe is removed from the machine.

The wiper 9 is supported on a wiper holder 244 a forwardly extending portion of which (Figs. 3 and 4.) is provided with a slot 246 which receives the left-hand portion of the wiper, the rear edge of the latter abutting against the holder at the rear of the slot. The wiper is fastened to the holder by a pin 248 slidingly mounted in the holder and arranged to enter a hole 250 (Fig. 10) in the wiper. The pin 248 is controlled by a spring 252 against the resistance of which it may be pulled upwardly to release the wiper by means of a knob 254 fast on its upper end. The rear edge of the right-hand portion of the wiper abuts against a vertical face 256 on the wiper holder, this face being extended vertically far enough to engage a wiper of any shape mounted in the machine. Further to fasten the wiper in fixed relation to the wiper holder there is provided a latch 258 arranged to engage 2. lug 260 on the right-hand end of the Wiper. This latch also is vertically extended far enough to engage a wiper of any shape, and it is mounted to swing about an eccentric portion 262 (Fig. 5) of a shaft 264 which is rotatable in upper and

lower arms

266 and 260 of the wiper holder. Fast on the upper end of the shaft 264 is a handle 2'10 for turning it. Two springs 212 and 214 (Figs. 2 and S) are arranged to extend through openings in the latch 258 and in the wiper holder and tend to swing the latch toward the left (Fig. 3), these springs being anchored at one end to a pin 216 in engagement with the latch and at the other end to a pin 218 in engagement with a vertical face on the wiper holder. the eccentric portion 262 of the shaft 264 is a finger 280 which is arranged to engage the latch 258 and swing it away from the wiper when the shaft 264 is turned far enough in a counterclockwise direction (Fig. 3). Before the finger 280 thus engages the latch the latter is moved forwardly away from the lug 260 by the action of the eccentric portion 262 of the shaft. In mounting a wiper in the machine the operator locks the left-hand portion of the wiper in proper position by means of the pin 248 while the latch is in its forwardly displaced position and then swings the handle 210 in a clockwise direction to force the latch rearwardly against the lug 260 and thus to clamp the wiper firmly against the face 256. The position of the eccentric portion 262 of the shaft 264 is then such that it holds the latch against reverse forward movement when the operator releases the handle 270.

The wiper holder 244 is secured by a key 282 and a set screw 284 (Fig. 3) on the front end of a shaft 286 which is arranged to extend widthwise of the shoe and is supported for turning movement in front and rear bearings 288 and 290 (Fig. 2) on a wiper carrier 292, the shaft being held in place by front and rear bearing caps 294 and 296. Between its front and rear bearings the shaft 286 has formed thereon a flange 298 (Fig. 4) from which extends a finger 300 having a rounded end located between upper and

lower flanges

302 and 304 formed on a rod 306 which is mounted to turn in a bearing in an arm 308 fastened to the cap 294. At its lower end the Fast on rod 306 is threaded in the wiper carrier 292, I

sometimes be desirable to position it in the best relation to the shoe on which it is to operate. An indication as to how the wiper is thus adjusted is afforded by a pointer 3I2 which is fastened to the rear end of the shaft 286 and cooperates with a scale provided on an upwardly extending portion 3I4 of the bearing cap 296.

The wiper carrier 292 is pivotally supported in a location comparatively remote from the shoe on the upper end of a lever arm 3I6 mounted for forward and rearward swinging movements on a rod 3I8 extending lengthwise of the shoe and supported at its opposite ends in lugs on the top frame plate 4. In a location nearer the shoe than the arm 3I6 the wiper carrier is pivotally supported on the upper end of a link 320 the lower end of which is pivotally supported as hereinafter described so that the link may swing in the same directions as the arm 3I6. The arm 3I6 and the link 320 thus constitute, in effect, a parallel link support for the wiper carrier. Integral with the hub 322 of the arm 3I6 is a downwardly extending arm 324 which is connected by a link 326 to an arm 32B fast on the previously mentioned rock shaft 228 which is turned by the hand lever 240. It will thus be seen that by forward movement of this hand lever the wiper carrier 292 is moved forwardly to carry the wiper 6 toward the shoe and to cause it to wipe the margin of the upper inwardly over the insole. For limiting rearward movement of the wiper carrier there is integral with the hub 322 an arm 330 which carries a screw 332 the head of which is arranged to engage the lower face of the top plate 4.

The link 320 is pivotally connected at its lower end to an arm 334 the hub portion 336 of which is mounted to turn on the previously mentioned rod I52 and carries another arm 338 connected by a link 340 to an arm 342 fast on one end of a rock shaft 344 mounted in a bearing in the frame. Fast on the other end of this rock shaft is a double-acting treadle 345 (Fig. 2) provided with front and

rear foot pieces

348 and 350. It will thus be seen that by depression of the rear foot piece 350 of the double-acting treadle the operator may swing the wiper carrier 292 upwardly about its pivotal connection with the arm 3I6 and that by depression of the front foot piece 348 he may swing the wiper carrier in a downward direction. By this means, therefore, the operator determines the position of the wiper heightwise of the shoe in the lasting operation and causes it to apply the required downward pressure to the margin of the upper over the insole. The weight of the front portion of the wiper carrier and of the parts supported thereon is partially counterbalanced by a spring 352 connected to the link 320. The wiper carrier is guided and steadied during its movements by a casting 354 which is fastened to the top plate 4 and is provided at its upper end with plane vertical faces 356 and 358 (Fig. 3) arranged to engage the opposite sides of the wiper carrier. Threaded in an offset portion of this casting is a vertical screw 360 the upper end of which is arranged to engage the wiper carrier 292 to limit adjustably downward swinging movement of the carrier.

In the use of the machine the operator first mounts on the wiper holder 244 a wiper 6 appropriate for shoes of the style and size to be operated upon, and then presents such a shoe in the position determined by the plate 8 and the pins I and by depression of the treadle I54 raises the toe rest II6 to clamp the shoe against the plate, the toe rest being locked automatically in shoe-supporting position by the lever I58. In thus presenting the shoe the operator depresses the rod I90 to a position determined by engagement of the top of the cone of the last with the button I9I on the upper end of the rod. The operator may then adjust the shoe to position it in still better relation to the Wiper B by movement of one or the other or both of the hand wheels 16, III], preferably moving the wiper forwardly into engagement with the shoe and raising it as may be required by means of the double-acting treadle 346 to assist in determining when the shoe and the wiper are in proper adjusted relation for the best results in the lasting operation. He may also at this time adjust the wiper about the axis of the shaft 286 by use of the hand crank 3H]. It will be understood that when these adjustments have been made no further adjustment will be required until a shoe of a different size or style or having upper materials substantially difierent in character is to be operated upon.

After relatively adjusting the shoe and the wiper as above described, the operator proceeds to last the rear side of the shoe, moving the wiper forwardly by the hand lever 246 and raising or lowering it by the treadle 346. The wiper may be so operated as to engage the upper a little below the edge of the insole and wipe it upwardly before wiping its margin inwardly over the insole; and in the course of the wiping operation the operator may, by the use of hand pincers, pull the upper over the last and the edge of the insole in one or more locations as the condition of the work may require. After wiping the margin of the upper inwardly the operator presses it firmly down on the insole by use of the treadle 346 and, in accordance with the procedure herein illustrated, in the lasting of a shoe of the type in which the lasted margin of the upper lies in generally parallel relation to the bottom of the last, he then drives tacks with a hand tacker through holes 362 provided in the wiper for this purpose, the tacks being clinched on the usual metal plate on the bottom of the last, as shown in Fig. 11. It will be, understood, however, that alternatively cement may, if desired, be used to secure the upper materials of such a shoe in lasted position, in which case it is only necessary to depress the wiper by means of the tread1e346 to effect the upper-securing operation. During the lasting operation the last and shoe are firmly supported at the heel end by the rod I90 which is locked against downward movement by the wiper-operating movement of the lever 246. After the lasting operation has been completed the operator raises the wiper and moves it rearwardly away from the shoe, the supporting rod I90 being unlocked by the rearward movement of the lever 24!]. By depression of the treadle I12 he then releases the toe rest to permit it to return to its starting position, and thereafter removes the shoe from the pins Ill. As hereinbefore explained, the other side of the shoe will thereafter be lasted in the same manner by use of another machine constructed as herein disclosed except for such changes as are necessitated by the positioning of the shoe with its toe end pointing toward the right instead of toward the left, the frame and other parts of the machine herein shown being so designed that comparatively few changes are necessary in order to provide a companion machine of that character.
