The rear end of the link 22 is pivotally mounted on an upwardly extending iorlted member 26 fast on the frame plate 8,
and the lever M is also pivotally mounted be tween its front and rear ends on a pin 28 on this member. extending arm of the lever 24 accordingly have the effect of parallel links supporting the block i l for upward or downward movement without any tipping movement thereof. extending arm of the lever 24 has pivotally mounted on its rear end 9. depending arm 30 provided with a plate 32 an edge of which is arranged normally to extend over the top of a plate 34 fast on the frame plate 8, so that the arm 30 serves as a latch for positively preventing upward movement of the holddown 8 in response to pressure of the shoe thereon. A spring 38 connected to the arm 30 and to the plate 6 holds the arm normally in operative position. A further purpose served by this latch arm will be hereinafter explained.
The shoe is positioned laterally in the machine by two side gages 38 arranged to engage it at the opposite sides of the forepart, respectively, these gages comprising plates faced with leather or other suitable material and pivotally mounted on vertical pins 40 supported on the front ends iii The link 22 and the forwardly The rearwardly of the bottom of the shoe.
of forwardly and rearwardly extending levers l2. gages are curved lengthwise of the shoe to approximate the contour of the shoe and by swinging about the pins 413 are permitted to adjust themselves to the shoe. The levers 42 are pivotally mounted between their front and rear ends on vertical studs 44 extending downwardly from the top plate 6, and their rearwardly extending arms are forked to embrace a rod 45 rotatably mounted on the frame. This rodis provided with right and left screw threads 48 in engagement with corresponding threads in blocks to against the outer faces of which the iorlted rear end portions of the levers t2 bear, the blocks being held from turning by contact with the plate 6. A spring 52 connected to fingers M on. the rear ends of the levers holds the levers constantly against these faces of the blocks. Lengthwise movement of the rod 46 is prevented by two collars 5B and 58 fast on onposite endsthereoi and engaging the frame, the collar being knurled for use in turning the rod. It will be understood that by the turning of the rod the blocks 50 are moved equal distances toward or from each other to adjust the side gages 3B for shoes of different widths, the adjustment being preferably such that while the gages determine the position of the shoe with sufficient accuracy they do not apply any substantial pressure to the upper. After the shoe has been presented by the operator under the holddown B and between the side gages 38, it is clamped against the holddown substantially at the beginning of the power operation of the machine by a shoe rest 60 which engages the top of its forepart underneath as illustrated in Fig.
7. Th shoe rest 60 is supported on a lever arm 82 which is fast on a rockshaft 84 mounted in bearings in the frame. The means for operating the arm 82 to apply the shoe rest to the shoe will be hereinafter described.
For wiping the margin of the upper inwardly over the insole along the opposite sides of the forepart of the shoe, the machine is provided, like that shown in the last mentioned Letters Patent, with a pair of'wipers 66 consisting of comparatively thin 'steelplates which are resiliently flexible in directions heightwise of the shoe to permit them to conform to the contour These plates are secured, each by a pair of bolts 58. to forwardly extending arms 10 of bell-crank levers l2 plvotally mounted on studs 14 on the top frame plate 8 to swing about axes extending heightwise of the shoe. The bell-crank levers 12 have other arms 18 extending generally widthwise of the shoe in crossed relation to each other and connected respectively by links 18 to the opposite ends of a bar which is integral with the upper ends of arms 82 of two other bell-crank levers B4 mounted to swing about a rod 86 on the frame, the levers 84 being further joined together by a. hub 88 on the rod. The links 18 extend through openings in the bar 80 which are large enough to provide for the necessary play, and they are provided with nuts 90 and 92 arranged to engage the bar respectively on its front and rear sides. The bell-crank levers 84 are further provided with forwardly extending arms which are connected near their front ends by a pair of downwardly extending links 88 to a piston 88 movable vertically in a cylinder Hi0 formed as part of the column 2, the piston being operated as hereinafter described. The links extend downwardly within the cylinder and are connected to the piston 98 by'a pin I02, the upper end portion of the piston being provided on its opposite sides In response v engagement with shoulders I04 formed on caps I06 which are secured to the top frame plate 6.
w 6 the shoe rest 60 to the shoe. After the shoe rest has arrived in shoe-clamping position the spring [I48 is compressed by further movements of the bell-crank levers to hold the shoe rest forcibly against the' shoe; the rod I40 moving upwardly through the member I44. As the links 96 thereafter continue their upward movements tool)- 1 crate the wipers,'the rolls I28 are engaged by vertical faces I52 on the projections I20 to maintain the shoe rest in shoe-supporting position, as
illustrated in Fig. 2
Return movements of the arms to withdraw the 1 wipers 66- from over the shoe are effected by springs I08 connected to the forwardly extending arms 94fof the bell-crank levers 84 and to the frame of themachine, these movements of the arms I0 being limited by their engagement with shoulders 0 on the caps I06. .The caps serve also to prevent the wiper-carrying; arms from being sprung upwardly by the upward pressure of the shoe'on the wipers. The wipers are main-' them and the side gages 38. The heating units are supplied with current from a suitable source through flexible conduits IIB, attached to the blocks H4. The studs 14 about which the wipers are swung are so. located that the portions of the wipers whichact on the margin of the upper have components of movement lengthwise of the shoe toward its toe end, which is desirable in view of the inward curvature of the edge of the shoe bottom heelwardly of the ball line. Since shoes on which the machine-operates may some- When a shoe is pressed upwardly against the holddown 8 by the shoe rest 60 as above described,
the lever 24 which supports the holddown is held positively against movement in response to pressure of the shoe on the holddown by the latch arm 30. When the wipers 66 are over the shoe bottom it is desirable to increase their pressure on the shoe to insure that all portions of the margin of the upper on which they act will be pressed firmly down on the insole into position to be secured thereto by the cement. The need for such increase of pressure further arises from the fact that the holddown is preferably so adjusted as to provide substantial clearance initially between the wipers and the insole to assist in guarding against displacement of themargin of the insole by the inward movements of the wipers. accordingly such that when. the wipers have nearly completed their inward wiping movements the latch arm 30 is swung rearwardly to release the lever 24, thus permitting the shoe rest times have therein upstanding pulling-over tacks at the sides of the toe, the wipers are provided with recesses I I8 to clear such tacks.
In. the machine herein shown the upward movement of the piston 98 is further utilized to impart upward swinging movement to the arm 82 and thereby to apply the shoe rest 60 in clamping and supporting engagement with the.
shoe. For this purpose the two bodily movable links 96, through which the wiper-operating bellcrank levers 84 are operated as hereinbefore de scribed, are provided with forward and rearward cam projections I 26 (Figs l and 3) arranged to control two bell-crank levers I22 mounted to swing about rods I24 on the frame. One arm iZt of each of these bell-crank levers carries two rolls I28 normally engaged by inclined cam faces iSt on the projections I20. The other arm I32 of the front bell-crank lever is connected by a pair of links 536 to a pin I36 mounted in the lower end of a inverted U-shaped member I38 to which is secured an upwardly extending rod Mb.
The other arm I32 of the rear bell-crank lever is similarly connected by a single link M2 to the pint. Surrounding the rod I40, between the member I38 and a member I confined on the upper end of the rod by nuts I46, is a compression spring Mb. 'The member I44 has apair of upwardly extending arm's I pivotally connected .to the front end of the arm 62. At the very'beginning of the upward movement of the piston 98, therefore, the inclined cam faces I30 act on the rolls I28 to swing the bell-crank levers I22 in the directions to lift the U-shaped member I38, and this member acts through thespring I48 and the member I44 to impart upward swinging movement to the arm 62 and thereby to apply bell-crank levers 84 and having thereon a nut I arranged to be engaged by the bar 80 to operate the latch arm at a time in the movements of the wipers" determined by adjustment of the nut. When the lever 24 :is thus released it-is swung by the pressure of the shoe on the holddown against the resistance of a light spring 358 mounted between its rear end and the frame plate 6, this spring being provided for thereifter returning the lever into position to permit the latch arm 30 to be returned to its normal position by the spring 36. The spring I58 is held. in proper position by .'a screw I60 extending downwardly within it from the lever '26. When the shoe is thus pressed upwardly against the flexible wipers they bend to conform satisfactorily to the more or less convex curvature of the bottom of the shoe, the bending of the wipers being limited and controlled by screws I62 on the arm lil in the same manner as in the machine shown in the last mentioned Letters Patent.
Arranged to cooperate with the wipers 60 to control the upper are retarders I64 which clamp the margin of the upper in upstanding position against the edges of the wipers and also serve to press the margin of the insole down on the bottom of the last as the wipers begin to wipe the upper inwardly over the insole. Preferably, as shown, the retarders are curved lengthwise of the shoe somewhat more sharply than the edges of the wipers, so that portions of the upper which may have been previously lasted in the shank or pulled over-at the side of the toe will not prevent the retarders from being moved outwardly as far as desired at the widest portion of the shoe.

thus drawing the upper tightly over the edge of the insole. Shortly after the wipers begin to wipe the margln oi the upper inwardly over the insole, however. the retarders are lifted against the resistance of the springs I18 to withdraw them from the pztths or the wipers. For this purpose there are mounted on the arms I68 members 208 (Figs. 4 and ii) having ears extending downwardly through slots in the arms and supporting rolls rm which are engaged by the wiper-carrying arms "Ill to swing the arms I68 upwardly about the pins I10 and thereby to lift the retarders. The members 208 are clamped on the arms I88 by screws 2I2 which extend through slots in the members to permit the latter to be adjusted to determine precisely the time in the inward movewhich is supported last in the upwardly extending arms or a lJ- haped member I36 having a downwardly extending stem iiid mounted to turn in a bearing termed in u bracket IMI oh the frame oi the machine. ltlso mounted to swing about the rods I84 are the forked outer ends of arms I92 (Fig. 3) which extend inwardly toward each other'and have rounded innor ends engaged by the iorked i'ront ends of the previously mentioned. wiper-operating arms 94. When these arms, therefore, are swung upwardly to operate the wiper they impart upward swinging movements also to the arms I92. These movements of the arms I92 cause outward swinging movements laterally of the shoe to be imparted to the arms M2 by torsion springs I94 which surround the rods I84, one end of each spring bearing against a lug I95 (Fig. 5) on the arm I12 and the other end against a pin I98 mounted in a collar Zllii fast on the rod illt. The normal positions oi the erms till relatively to the arms illii are udjustuhly determined by serews 205i which. mounted in extensions 2Il4 oi the limited ends oi. the urine and engage the outer sides oi orms i'iii.
'iYhe outwei'd swinging movements oi the arms Ill? which result iron: upwsrd movements of the arms Hill, as above described, serve to move the retarders I64 from positions near the holddown 8 (Fig. i) outwardly over the insole toward the wipers as the wipers are being moved inwardly toward the side edges or the insole, the rethe side edges of the insole, as illustrated in Fig.
8,'so as to detach from the edges or the insole any. portion or the upper which may have adhered prematurely thereto. In order that the retarders will be properly positioned relatively tothe side edges of the insole when the upper is first clamped against them by the wipers in operating on shoes or different widths, the arms I12 are adjusted relatively to the arms I92 by the screws 202 to posiments of the arms III when the retarders are lifted. moved upwardly far enough to clear the wipers they are moved outwardly over the wipersas the wipers continue their inward movements, by the springs I94 acting on the arms I12. Early in such outward movements or the retarders they serve to bend the margin of the upper outwardly over the ed es of the wipers, as illustrated in Fig. 10, and thus to increase the effectiveness of the wipers in wiping the upper tightly and smoothly overthe insole. Outward swinging movements of the arms I12 are adjustably limited by screws 2 arranged to engage the arms and mounted in brackets 2l 6 on the frame.
Under some conditions it may be desirable that the retarder I64 which cooperates with the wiper acting at the outer side of a right or a left shoe shall be positioned somewhat farther from the end of the toe than the other retarder. Accordingly the construction herein shown provides for relative adjustment of the retarders lengthwise of the shoe. For this purpose diametrically enlurged portions of the rods I84 extending lorwardly of the arms 192 are connected together.
by a crossbar 7H8 the opposite ends of which are pivotaliy mounted on pins 220 on the rods, and the right-hand rod I M is extended still farther forwardly to provide a handle 222 (Fig. 4).. By
means of this handle, therefore, the two rods I84 may be swung simultaneously in the same directions about the axes of the studs I88, and it will be evident that such swinging movements of the rods are accompanied by swinging movements of the arms I88 in opposite directions respectively lengthwise or the shoe to position one of the retarders nearer the end of the toe and the other farther from the'end or the toe. When the retarders have thus'been adjusted as required for a right or a left shoe, they will ordinarily maintain their adjusted relation without special retaining means, although such means may be provided if desired.
Upward movement of the piston 98 to operate the wipers and other parts is efiected by operating fluid, preferably compressed air, admitted to the lower end of the cylinder I00 through a pipe 224. The air is thus admitted by a valve 226 controlled by a solenoid 228 which is energized by the clos- When the retarders have thus been ing of a switch 230 in response to the presentation of a shoe to the machine, the toe end of the shoe engaging a pivotally mounted starting member 232- which acts on the switch through a bell-crank lever 234. After the wipers have been moved inwardly over the shoe bottom they remain in pres-v sure-applying relation to the'margin of the upper during a short interval which is terminated by the opening of the switch 230 in response to upward movement of a piston 236 mounted in a cylinder 238 which receives compressed air throughan adjustable needle valve 24s. The parts of the machine then return to their starting positions. A more complete disclosure of the means for thus controlling the operation of the machine will be found in the previously mentioned application oi which this application is a division.
movement of the piston Sill operative movements then imparted. to the wiper-operating bellcranlr levers lid. At the beginning of the up ward movement of the piston the two bell=-cranh levers H22 are operated by the cam faces on the projections tilt of the links till to move the shoe rest Gil upwardly into position to clamp the shoe against the presser feet ill of the holddown the spring Mil being compressed to maintain the shoe rest in clamping position. This action oi the shoe rest on the shoe causes the latter to raise the retarclers ltd slightly until the insole engages the presser feet ill. As the piston tld continues its upward movement to operate the wipers the rolls E28 or the bell-crank lever :12? rest against the vertical faces use of the projections lid, as shown in Fig. 2. Simultaneously with the inward movements of the wipers the arms i are swung upwardly to cause the springs i943 to impart outward swinging movements to the arm ill and thereby to move the retarders ltd outwardly over the insole toward the incoming wipers. The retarders thus serve to spread portions of the margin of the upper outwardly from over the insole, and when they arrive in positions where their upper-engaging faces at the widest portion of the shoe are positioned slightly farther outward than the side edges of the insole, as illustrated in Fig- 8, the wipers arrive in positions to clamp the upstanding margin of the upper against them. As the wipers thereafter continue their inwardmovements they force the retarders inwardly against the resistance of the springs B94, and in this operation the wipers and the retarders' serve to apply an inward pull to the margin of the upper over the extreme edge of the insole, as illustrated in Fig. 9, the retarders at the same time pressing the margin of the insole down on the last to prevent it from being displaced bythe wipers- Substantially at the time in the operation of themachine indicated by Fig. 9 the wiper-carrying arms 10 arrive in positions to engage the. rolls 2), and by their further movements they act on these rolls to swing the arms I68 upwardly against the resistance of the springs I16 and. thereby to lift the retarders I 64. When the retarders have'thus been lifted farenough they-are moved outwardly the wiper-carrying arms lo the switch to start the machine." By upward till rearwardly and thus over the wipers by the action of the springs l 94, and early in such outward movements they serve to bend the margin of the upper outwardly over the edges of the wipers, as illustrated in Fig. 10.. thus increasing the eflectiveness f the wipers in wiping the margin of the upper tightly inward over the insole. In completin their inward movements the wipers wipe the margin of the upper throughout its width into parallel relation to the insole, as shown in Fig. 11. Shortly before arrive in the positions determined by their engagement with the shoulders tilt, the bar 80 of the bell-crank levers dd acts on the nut H538 to swin the latch arm to release the holddown d. "Ihe spring Mt controlling the shoe rest Elli then serves to force the shoe farther upwardly against the wipers to increase their pressure on the margin of the upper and to cause them to bend into better conformity to the contour of the shoe bottom. The wipers having completed their inward movements, they remain in pressure-applying relation to the marginof the upper until the piston 236 has been raised far enough by the compressed air admitted beneath it through the needle valve to cause the switch 2369 to open. When the circuit through the solenoid is thus broken the valve is returned to its initial position and the air is released from the cylinders tilt] and The parts are then returned to their initial positions, the wipers being Withdrawn from over the shoe by the action of the springs Mill on the bell-crank levers 543, and the shoe is released to permit the operator to remove it.
