ASSEMBLING MACHINE.

Application filed September 14, 1917. Serial No. 191,469.

To all whomit may concern.

Be it known that LYVILLIAM C. STEWART, a subject of the King of England, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented. certain Improvements in Assembling lviachines of which the following description, in con nection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for assembling parts of boots and shoes upon their lasts preparatory to the pulling-over and lasting operations. For the purpose of illustration, an embodiment of the invention is herein shown as applied. to a machine 01" the type described in Letters Patent of the Unitei States No. 1,356,510 granted october 26, 1920 on application oi Hannah nshton, executrix of the will of Orr-ell Ashton. l" is to he understood, however, that the invention is not restricted to embodiment in a machine of the par 'icular type disclosed in said patent.

In the earlier machine, above referred to, mechanism is provided for inserting tacks into the shoe bottom through the flange of the counter or hcel stiffener and into the heel seat. the tack: mechanisms being erried to a point leyond the ups-itamliug margin oi. the upper and the tacks inserted through the flange of the counter and the innersole without passing through the upper. It is important that these tacks, which may be termed counter-flange tacks, be driven at predetermined distances from the last edge, .notwithstaudii ariations in widthot the lasts i prei' -a le that they should be so it ated ind dri i automatically.

important feature of this inventio for insur' not t counter tacos l? alive. predete mined distances from the edge, rres ui ctively of the. widtl'l oi he last.

shown herein, the hinge tackers and shoe 1 seat are at predetermined distances from the last edge. The tackers are preferably positzoned near to ether during the r'movement of advance over the heel seat so that they will more readily pass beyond the upstanding margin of the upper at the rear of the shoe and are then separated to their tack driving positions. The separation of the tackers is preferably effected by mechanism which is positioned in accordance with a dimension of the shoe and which calipers, for example, the width of the shoe, the calipering mechanism co-operating with means on the tackers during their movement of advance over the shoe bottom to cause them to separate until they are located at predetermined, constant, and preferably equal distances from the opposite edges of the last bottom.

In the machine of the prior patent refferred to above the counter tackers, after they have advanced over the shoe into tack driving position, are out of contact with the work, there being a spacebetween the ends of the t acker nozzles and the flange of the counter. The tacks, therefore, have to be driven through the air. As a conse quence the points of the counter tacks sometimes shoot sideways and the tacks are therefore not driven straight into the work.

Another feature of the present invention consists in. means for insuring that the counter tacl f. mechanisms have their tack nozzles or holders moved toward the work before the taclcs are driven. As herein shown, the tack holders are mounted For limited movement toward the work, and means operated by movement of the tack drivers in the early part of their descent is provided to move the tack holders into contact with the work in advance of the action of the drivers to drive the tacks through the tack holders into the work. In the illus trated embodiment of the invention this movement of the tack holders eflccted yieldingly through suitable springs.

in the ma ....no she v'n in the patent above l"- l=. QTi'(l to. mechanism including a fined lower abutment s provided for rigidly :ci: nping the shoe upper against the cone of the, last at a point remote from the last hottoin while the margin of the upper estending above the bottom oi? the lastv is seized and tcnsioned over the heel seat as the wiper advances. It is desirable that the lower abutment accommodate itself to different sizes and shapes of lasts so that theywill,

be pro iierly positioned in. the machine for the action of the'gripper, wipers, and other operating mechanism without attention of the operator and without his taking time to make adjustments.

.-i .n.ot-'her feature of the present invention consists, therefore, in means by which the lower abutment is rendered self-adjustii-ig to lasts or? different sizes and shapes, and means by which the abutment,after the last has reached a predetermined position in the machine, is rendered unyielding to permit the last to be clamped-in the machine by .rearward'ly directed pressure. As shown herein. the lower a l'niitment is mounted for movement longitudinally of the shoe. and. the upper abutment is imilarly moimtcal, mechanism being provided. for rendering the lower ubutment unyielding when the upper abutment is moved reznwvardly or inwardly. Y J

It is important that the margin of the upper at the rearof the heel seat be properly located between the end of the wiper and the gripper which co-operates with it to seize the upper margin before the machine is started. In the normal operation of the n'n'ichine the shoe is, lowered as it is swung the gripper the shoe is per is positioned. directly inside the margin of the upper .l11(l against the heel seat or 'flang eo fthe counter and carrirnl with the shoe'as the shoe is pushed 'h'irthcr into the machine.

Another feature of the invention cons in the combination with gripping means and operating menns'therefor, of means torrenderi'ng the "operating means inoperative until the gripping means has been closed upon the stock. The gripping means may comprise a wiper and a gripping element (xi-operating therewitln the mechanism being organized to prevent movement of the gripping element by the operating means unless the gripping element is moved toward the wiper and in to proximity to the wiper in position to do its work. Thismechonism prevents thence chine from hein .tarted until the gripper properly loc ted relatively lo' the u .11 it is to seize and the shoe is on tioned iii the ma .llIlG.

also inrportzint that the wji th of the toxin"; or of the F? up when a whole uuip d, lro'n'i the seam uniting the lore ing and quarter to the heel seat be constant inshoes of a given style. Accordingly, a, feature oi' the invention consists in means for positioning the shoe vertically with the seam uniting the quarter and foxing at a predetermined distance from the plane in which the wiper acts, so that by relative adjustment of the upper and the last the amount wiped over upon the heel seat may varied "to the Width of the foxing fromv the seamto the heel seat con stant. 5

'llhese and other features of the invention will appear more fully from the followingdetailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

The shoe is placed upon a last pin 8 and swung toward the machine. rar ying the pin 8 is depressible against a light spring not shown. hen the shoe A "post i. l l

rises, after being depressed and moved toward the machine the margin of the upper at the rear of the heel seat rises between n gripping element il'ln'nied as a jaw 26 and i '1he wiper is z-shown in. F. t or teeth apted in formations on the a. T-way 32} on a. relatively fixed part 35 se cured to the frame. Upon the rear end of the slide 3]. is secured a block 32 on which is a ratchet plate 34 having rearwardly directed teeth'36: Below the plate 34 is mounted a pairoitpawls 38 on a pin 40 which is sup- 7 30 is carried by a. slide 3]. having a T-guide 33 engaging aiilvancing wiper so that theportion of the upper at the rear of the shoe which lies above the lower abutment 30 will be tensioned as the wiper and gripper move over the shoe bottom.

7 The shoe having been positioned as described, the treadlc 86 may be depressed to start the machine, whereupon a hook 110 co-operates with a roll 112 on the jack member 6, as is fully described in the first abovementioned prior patent, to draw the shoe in wardly of the machine, lock it from downward movement, and clamp the portion of the shoe adjacent to the edge of the counter which is most remote from the sole against the abutment 30 which has been locked against further movement in response to pressure of the shoe against the upper abutment 54 as described. As the hook 110 descends to lock the jack, one arm 116 (Fig. 1) of a bell-crank lever pivoted at 118 is re leased, causing the other arm 120 of the lever to permit inward movement of side pressers 122, 124 under the influence of springs 126, all as described in the first above-mentioned prior patent. to Fig. 10, which shows the side presses 122, 124 in operative position against the sides of the shoe, it will be seen that these pressers are carried by arms 128, 130 which are mounted on rock shafts 131 and are moved toward the shoe by the springs 126 and serve to measure or caliper the width of the shoe across the heel seat portion.

Before the wiper 28 begins to advance, a. tack is driven through the lower V-block or abutment 30 as described in the said firstmentioned patent, additionally to secure the upper already firmly held clamped against the last at that point.

The wiper and its operating mechanism are substantially described in United States Letters Patent No. 1,204,928, granted November 1.4, 1916, on application of Orrell Ashton, and need not be described in detail herein. After the driving of the tack through the lower abutment 30, the cam 102 allows the gripper to clamp the upper against the Wiper in the manner described and the wiper advances over the shoe bot tom, thereby tensioning the upper at the rear of the shoe, and wiping it into place on the heel seat along the longitudinal median line of the heel, atack supplied by a tack tube 132 being driven by a central.

driver 134 when the wiper reaches its posi tion of farthest advance over the shoe bottom. Mounted upon each side of the central driver 134 and carried by the wiper carrier 29 are two counter tacker frames 136, 138 which are mounted for movement laterally of the shoe bottom by bolts 139 which pass through holes 133 in tacker frames 136, 188 and through slots 137 in brackets 141 secured t0 the wiper carrier 29 (Fig. 7).

Referring The bolts 139 are provided with spacing collars 1.45 (Fig. 8) which are longer than the thickness of the brackets 141 so that when the nuts of the bolts 139 are tightened, the bolts will still be free to move in the slots 137. The tacker frames are held toward each other by a spring 143, as shown in Fig. 6. Tacks are supplied to these tackers by tack tubes 140, 142, and the tacks are driven'by drivers 144, 146 having universal joint connection with a head 135 which also carries the driver 134 and is operated by a driver lever 174 in the usual manner. On the lower side of each of the tacker frai'nes 136, 138 is a cam rol l 150. The cam rolls 150 are mounted on blocks 152 which are clamped upon flanges 155 on the lower portions 165 of the tacker frames by screws 154 as is best shown in Fig. 8. The rolls 150 co-operate with cams 156, 158 formed on the arms 128, 130 which carry, respectively, the side pressers 122, 124. The position of the drivers and, of course, of the tackers before they begin to advance over the shoe bottom is indicated in Fig. 9. As the tacker frames advance over the shoe bottom with the wiper, the rolls 150 engage the cams 156, 158 which are so shaped as to separate the tackers as they pass beyond the portion of the upper folded over by the wiper and to position them at a predetermined distance from the last edge and, of course, from the shoe engaging faces of the pressers 122, 124. After the tackers have been fully separated, the direction of the cam faces on the cams 156,158 changes so as to be substantially parallel with the movement of the wiper, and the tackers are moved forward a short distance Without being separated further. The final position of the side tackers is indicated in F ig. 10 by the cross section of the drivers 144, 146. By loosening the clamp screws 154, the rolls 150 may be'adjusted relatively to the tack ers so as to vary the position of the tack with respect to the edge of the last, and, if desired, to locate the tack on one side nearer to the edge of thelast than on the other side. The tacks, however, are preferably driven mptridistant from the edge of the last and substantially midway of the inturned flange of the corner. The tacks supplied by the tack tubes 140, 142 are delivered to tack holders. each comprising two parts 160, 161 (Fig. 8) pivoted to amember 163 and held together by a spring 162, so as to separate when the drivers descend to drive the tack held between them. The inner faces of the members 160, 161 are recessed and by separating the parts against the tension of the spring 162 they may be assembled upon the projections 165 extending downwardly from 1 movement of the tack holders 160, 161 and of the members 163 which. are pivoted to the t acker :lrames 188 by pins 164. Each tack holder is held in elevated position by a spring 166 connected between the adjacent tacker frame and a pin 169. To each oi the tack holder parts 160 is pivoted at its lower end a bar 168 by the pin 169. The bars extend upwardly along the tacker frames and have at their upper ends laterally bent portions having holes through which pass respectively, the drivers 144;, 1 16. Above the ends of the bars 168 are springs 170 surmounted by washers 142. When the drivers 1414, 146 descend the head 135 carried by the driver lever 1741 engages the washers 172, and compresses the springs 170 which push downwardly on tne bars 168 overcoming the tension of the springs 166 and forcing the tack holders into contact with the work. the tack holders 160, 161 when no shoe is in the machine is prevented by the flanges 155 or by the block 15., clamped thereon. This dowiiward movement of the tack holders insures that they will come in actual contact with the work and prevents liability of the point 01 the tack shooting sideways and being driven in an inclined position as sometimes happens when tacks are inserted through the air, that is, from a tack holder which is slightly spaced from the surface of the work into which the tack is driven.

To maintain the width of: the ilioxing from the taxing seam to the heel seat constant, a gage, shown in Fig. 11, is provided. The e consists eta plate180 having in its front end a V-shaped notch adapted to receive the rear portion of the shoe. The plate is dovetailed into the upper face of the lower V-block 30 for movement longitudinallyot the shoe, this movement being limfited by a pin 182 engaging a slot 18% in the plate. The plate is maintained normally in "forward position by a spring 186 seated in a bore in the V-block and arranged to engage the rear end 01 the plate. The plate normally has a position slightly in advance of the face 01'? the V-block and the shoe, as it is swung into the machine, is positioned with its rear end against the plate 180 and is allowed to rise until its heel seat is properly positioned by engagement with the gripper 2 .3. The upper may then be adjusted downvardly or upwardly relatively to the last so that the lower edge of the toning will engage the top face of the plate 180. In this Rvay the width of the toning in any given style at shoe may be maintained constant. The V-blocks l e the usual vertical adjustment by looscni the clamp nut 188 (Fig. 2) and turning the hand wheel 190 and therefore. the gage may be readily adjusted vertically for dillerent styles of shoes, or if Excess downward movement ot' desired the lower V-block may be adjuster] vertically relatively to the upper V-lolock by loosening a clamp screw operated by a handle 189, Fig. 2.

iflechanism is provided as usual for driving a tack into the rear portion of the shoe through the upper V-block 54 preferably simul ancously with the driving of the tacks into the heel seat of the shoe. The mechanism herein shown but not fully described is equivalent to that shown in the prior patcnt first above-mentioned and will be readily understood by those skilled in this art. Tacks for the upper Vblock 54 are supplied by a tack tube 191.

While the operation of the various mechanisms has been given in connection with the detailed explanation, it may be convenient br efly to recapitulate. The shoe materials are prepared for the assembling operation by first securing a sole to the bottom of the last and placing over the last the upper materials comprising the lining and upper leather with a molded counter inserted be tween the lining and upper at the rear p0- tion thereof. The upper is held to the last at the torepart by the hand of the operator and the shoe placed upon the spindle 8. The post 10 depressed by downward pressure of the shoe and the shoe swung into the machine. The shoe is then allowed to rise and the upstanding margin of the upper passes between the gripper 26, and wiper 28, the end of tie gripper engaging the inturned flange of the counter. This locates the last vertically and the .upper is then pulled downwardly until the seam between the foxing and quarter engages the plate 180-, thus measuring the width of the foxing. The shoe is then pushed against the V-block 30, and being already in contact with the gripper 26 moves that inwardly of the machine and consequently moves the latch out of operative relation to the block 82 so that the treadle may be depressed to start the machine. The shoe after pushing the V- block 30 inwardly engages the V-block 54: and moves it inwardly, causing the pawls 38 to engage the teeth 36 and arrest further movement of the lower V-block 30.

The treadle is now depressed to start the machine. The hook 110 drops into engagement with the roll 112 to force the jack inwardly against the V-blocks and to clamp the shoe rigidly against the lower V-lolock 30 and also locks the post 10 against downward movement. At the same time the side clamps 122, 121 are released and are forced by their springs 126 against the opposite sides of the rear portion of the shoe. The tack supplied to the lower V-block 30 by the tack tube 192 is now driven through the clock into the cone of the last to assist in holding the already clamped upper against displacement during the uppc' tensioning operation of the gripper, this tack being preferably used in addition to the clamping action of the post wh ch is forcing the last against the now rigid V- block 30. The cam 102 next allows the spring 104 to force the gripper 26 toward the end of the wiper firmly to grip the stock which lies between it and the wiper. The wiper now advances, tensioning the portion of upper between the lower V-block 30 and the gripper and wiping it over the heel. seat of the shoe. The gripper preferably grips the upper firmly against the wiper and is timed by. its cam 102 to release the wiper as soon as the wiper has passed over the shoe bottom far enough to obtain controliof the upper and insure that the tension to which the upper has been subjected will be maintained by the pressure of the wiper against the heel seat. As the wiper advances the tacker frames 186, 138 are carried forwardly beyond the edge of the upper at the rear of the shoe and are separated by the action of the rolls 150 against the cams 156, 158 until the tack holders 160, 161 are located over the mid portion of the counter flange at each side of the heel seat and preferably at the corners of the heel seat, whereupon a tack is driven through each of the tack holders which are swung downwardly against the work about their pivots 16 1 prior to the insertion of the tacks by reason of the compression of the springs 170 during the downward movement of the drivers. A tack is driven also through the wiper 28 and through the overwiped upper as is indicated in Figs. 9 and 10. At the same time a tack may be driven if desired through the upper V-block. The driving of any one of the five tacks may, however, be discontinued or prevented by means shown and described in the above mentioned prior Patents No. 1,204,928 and No. 1,356,510. After the tacks are driven in the heel seat the wiper and its attendant tacking mechanism are raised out of contact with the work and retracted to normal position, the hook 110 is raised to free the jack and restore the side clamps to normal position, whereupon the machine stops, leaving jack free to be swung outwardly and the shoe removed.
