Patented Mar. 29, 1921.

Application filed October 20, 1916. Serial No. 126,715.

To all whom it may concern Be it known that I, THOMAS H. SEELY, a citizen of the United States, residing at Malden, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines of the type employed for working a shoe upper over a last and securing it in overworked position by repeated operations of the machine along different parts of the shoe.

terials are gripped by pincer devices which updraw or pull the materials to conform them to the last and then overdraw or carry the materials inwardly over the edge of the innersole, and a wiper is given movement to engage the upper materials and press or wipe them smoothly upon the innersole into lasted position. The upper materials are then secured in lasted position by fastenings, which are fed or delivered to the action of inserting mechanism. These operations are repeated successively on the diiferent portions of the shoe.

During the lasting operation on this type of lasting machine, and during the drivi11 of the fastenings or tacks, the shoe is ordinarily held by both hands of the attendant while his foot maintains the starting and stopping treadle depressed to continue the machine in operation. When the attendant has finished lasting one shoe, he places it upon a suitable rack or receiver and reaches for'a-nother shoe to be lasted. During this time it is expedient that the machine continue in operation, and in practice it is customary for the attendant to maintain the starting and stopping treadle depressed. Loss 01": tacks is liable to occur at this time, because in the absence of means to prevent, the tack feeding or delivery means and inserting mechanism remain. in operation when there is no shoe in the machine.

' In some machines of this general type. it has been proposed to suspendthe operation {if e tack eecling means h n shoe s In machines of this type, the upper manot imposition to be lasted, and in some cases also, the inserting mechanism has, under such condition, been held in inoperative condition. In these prior machines the act of the attendant in placing a shoe in the machine has been utilized to determine the delivery of tacks, and start the operation of the inserting mechanism. The means employed to this end has comprised some kind of a work rest, movement of which by the shoe in the hands of the attendant was necessary, and devices or" this character have ieen practically effective.

It is desirable in some cases, however, that the operative be relieved of the uncertain shoe positions and false-motions that may result where the effort of the operative is relied upon to initiate the tack delivery and tack driving functions, and an important feature of the present invention therefore, consists in means movable by operation of the machine to detect the presence or absence of a shoe and suspend the delivery of tacks when absence of a shoe from lasting position is detected.

This feature of the invention is carried into effect in the present instance by means oi the wiper which advances over the edge of the shoe to press or wipe the upper ma- 9 terials into lasting position :ter the reception of a tack prior to each tack driving operation. Should a shoe be '11 position to receive a tack, wiper controlled means maintains. the tack delivering'or tack delivery and tack driving means in operation, but should a shoe not be presented, as when the attendant reaches for another shoe, the wiper-controlled means is caused to suspend the delivery of tacks, or the delivering or tacks and the operation of the tack driving means.

Another important feature of the invention consists in a yieldingly mounted wiper,

which, as it moves over the shoe to perform its wiping action, presses yieldingly upon the upper materials to lay them to the last. This aspect of the invention, in the present instance, is carried into effect by giving the wiper a movement or tendency tomovement downward or in a direction toward the bottom of the last substantially at right angles thereto as it moves over the edge of the shoe. If, at this time, a shoe is held in lasting position, the wiper will enga e and press the up:

per materials down upon the innersole into lasting position as it wipes them inwardly, but should a shoe not be in position for the action of'the wiper, the latter will still perform its wiping movement, but being no longer sustained by a shoe in the handsof the attendant, it will drop in response to itsxyielding tendency and effect a suspension of the tackdelivering or the tack delivery and tack driving means.

Still another important feature of the present invention consists in the fixed work rest or support combined with means for suspending the tack delivering and tack drivingioperations when a shoe is not presented tow the action of the machine.

The above features of the invention and others-will hereinafter be described in connection with one good, practical form of the invention and then the several features will be made the subject of the claims.

In the drawings Figure l is a perspective view showing the fastening-inserting mechanism and the tack-delivering or feeding means, certain portions of the frame and other parts of the machine being omitted for clearness of illustration;

Fig. 2 is a side elevation with parts shown insection, illustrating more particularly the wiper control for the fastening-inserting and delivering means;

Fig. 3 is a view similar to'that of Fig. 2, with the parts shown in different position; 1 F ig; 4 is a perspective view of the fastening delivery or controlling means looking upward from the side-and front of the machine;

Fig. 5 is an enlarged detail, showing the driver lock and associated parts;

Fig. 6' is a plan view partly in section, showing the means for controlling the delivery of fastenings;

Fig. 7 is a view similar to that of Fig. 6, showing the relation of parts when the delivery'of fastenings or tacks is suspended; and

Fig. 8 is a view similar to that of Figs. 6 and 7, with apart broken away, showing the relation of parts when a shoe is in the machine and a fastening or tack is to be delivered to the inserting mechanism.

Machines of the type illustrated are usually provided with pincer mechanisms which, under control of suitable actuating means, successively act upon different portions of the upper materials of a shoe to updraw and overdraw them relative to the last on which they have been previously assembled. In connection with the pincer mechanisms, there is usually associated a wiper for wipingor pressing the material onto the inner-- sole in lasting position ready for the reception of fastenings. The pincer mechanisms are not shown in the drawings, because they are well understood by those skilled in the art, and may be substantially as fully decribed inthe- U. S.- Letters Patent No. 58-1,?tt, June 15, 1897. V

The head frame 1 of the machine, only a portion of which is illustrated, may be of any suitable character for the support of the various operating portions of the mechanism, and mounted thereon for reciprocating movement, on each cycle of fasteninginserting operation, is the slide2, technically known in the art as the'tack carrier slide. This slide may be appropriatelyoperated from any convenient moving part of the machine, or as fully illustrated and described in the patent hereinbefore mentioned.

Projecting from the tack carrier slide 2 V is an arm .3, to the lower portion of which 1s appropriately secured in a well-understood manner, the tack carr1er- 4; havinga passageway 5 for the reception of, tacks in succession from. a suitable raceway 6. or other convenient tack supply. Between'the. raceway 6 and the tack carrier 4c isthe means for selecting tacks. individually and in succession from the raceway, and deliver ing them singly to the opening 5 of' the tack carrier. This selecting means may be of any usual well understood type, such, for instance, as illustrated in the patent to Cavanaugh, Jr, No. 873,018, December '10,

190mm comprises a delivery table 7, Fig.

1, in which is mounted for reciprocating' movement in front of the raceway 6, the separator 8. The table 7 and separator 8 may be ,of usual construction, and similar to the like parts shown and described in the patent to Cavanaugh, hereinbefore mentioned, the construction being suchythat when the separator 8 is reciprocated longitudinally in front of the raceway 6, it will select therefrom a tack and transfer it to the tack carrier 4 for delivery to the tack inserting mechanism. l/Vhen a tack is thus transferred to the tack carrier, itis yieldingly held thereinby the holders 9, of usual construction, so. that as the tack carrier moves to. tack-presenting position relative to the inserting mechanism,,the tack will be prevented from d1slodgment inthe open 1 mally under the influence of an appropriate driving mechanism, as for instance, such as shown in the patents herembeforecalled to attention. In the present instance, the

driver bar is raised against its actuating spring by a cam 12, Fig. 5, mounted on the shaft 13 supported in the head frame 1 of the machine, the construction being such that when the driver bar 10 has been raised by the cam, and the cut-out portion of the cam passes below the usual projection from the driver bar, thellatter will be forced downwardly to perform its driving function under the impulse of the usual operating spring as indicated in the patents mentioned, as well understood by those skilled in the art.

' Adjustablysecured to a bracket 14, Fig. 1,0r to an appropriate portion of the head frame, is a block 15 carrying a work rest 16, against the end portion 17 of which the innersole of the shoe is held to position it for the tack-inserting operation. To assist in thus positioning the shoe, there is mounted on the head frame of the machine, an edge gage 18 which may be of anyappropriate character, but in the present instance is shown as an arm secured in fixed position. and having an edge against which the shoe may be pressed. The fixed work rest and edge gage 18 afford positive means for enabling the attendant to accurately position the shoe for the fastening or tackinserting action. As hereinbefore noted, it is customary for the attendant to maintain the machine in operation after he has finished lasting one shoe, and while he is reaching for another. During this interval, if the tack-delivering mechanism remains in operation, there will be, eventually, a loss of tacks, because no shoe is in the machine positioned to receive them. It is expedient that'the operative be relieved of the burden of starting and stoppingthe tack-delivering, functions of the machine by his manual effort, and a practical means to this end consists of a wiper which, in addition to its? wipingmovement, has an additional movement ofwhich it may partake when a shoe is not in posi tion tobe lasted, and means. are provided under the control of the wiper, to determine whether or not a tack shall be delivered or fed to the tack carrier. 9 In the present instance ofthe invention, the wiper consists of a member 19 pivotally mounted at 20 on the tack carrier 1, and consequently partaking of the tack carrier movement. When the tack carrier 4 is in its iwithdrawn position, to the right of Fig. 2, the wiper 19 moves over the top portion of the edge gage 18 and is maintained in its normal wiping position. Asthetack carrier 4: moves toward the shoe positioned by the work rest and the edge gage, it carries with it the wiper, which engages the upper materials and wipes or lays them onto the innersole into lasting position. how ever, no shoe'is presented for the action of the wiper, the ,latter is free to partake of its additional movement, which in the present instance of the invention, is afalling or depressing action, and this additional movement of the wiper under such conditions is utilized to stop the tack delivering operation, and preferably, though not necessarily, also, the tack drivingioperation, as will now be described.

Pivotally mounted at 21 on the tack carrier, is an arm 22, shown as of bell. crank shape, and having a downwardly-projecting end portion 23 passing through a slot 2 1 of the tack carrier and normally resting on the top of the wiper 19. The upwardly-extending portion of the arm 22 bears upon a longitudinally-movable rod 25 normally under the influence of a spring 26, said rod and spring being mounted in the tack carrier slidef2, the construction being such that should a shoe be in lasting position when the tack carrier slide, the tack carrier, and wiper move toward the shoe or to the left, Figs. 1 and 2, the wiper as it passes from the top portion of the edge gage 28 will encounter the edge materials of the shoe and as it wipes them over the innersole into lasting position, will be prevented from turning about its pivotal mounting-2O under the stress of the spring 26; but should the wiper 19 fail to encounter or detect the presence of the shoe in lasting position, it will drop into the'position of Fig. 3 as it performs its wiping function, thereby permitting the spring 26 to move the rod 25 to the left, Figs. 2 and 3.

To afford an adjustable connection between the rod 25 and the arm 22, the latter is provided at its outer portion with an adjusting device, such as the block 27, and the adjusting screw 28.

The tack carrier slide is provided with a slot 29, in which is mounted the sliding block 30, interposed between the rod 25 and the spring 26, the construction being'such that the spring'26 acts upon the block to move it longitudinally in the slot 29 when the wiper fails to detect and engage a shoe as it performs its wiping action.

To'afford a convenient means for holding the block 30 in its operative position and yet permit its ready removal whendesired, there is mounted on the tack'carrier' slide 2 a swing plate 31' secured to the tack carrier slide by appropriate means, such as the screw 32.

The tack carrier slide 2 has projecting from the side thereof, the lugs 33 between which is mounted a rocking member 34 by means of a bolt or other pivotal connection 35, the construction being such'that the rocking member 3 1 will move with the tackcarrierlslide.

lOO

Pivotally connected at 36 to the rocking A member 34: is a link 37 pivotally connected at 38' with a rocking segment 39 adapted to oscillate, as will hereinafter be described, aboutthe stud 40. The rocking segment 39 has a series of teeth 41 in operative engage ment; with a corresponding series of teeth 42, formed in a segment 43 secured to the upwardly-extending shaft 44, Fig. 6, the constructionbeing such that shouldthe rocking segment 39 be turned contraclockwise, Fig. 6, it will impart to the segment 43 a corresponding movement in the opposite direction and therebyturn the shaft 44.

The stud 40 has mounted thereon a sleeve 45'provided with a base portion 46 in which is. formed a series of capstan holes 47, and from which projects the lug 48 carrying a pin 49 against which bearsv one end of a spring 50, .the'other end whereof at 51' rests against a lug or projection 52extend'ing from'the hub' portion 53 of an arm 54 loosely mounted on the upright, shaft 44. The rocking segment 39 is clamped to the sleeve 45 by suitable means, such, for instance, as the bolt 55, the construction beingsuch that by loosening the bolt 55, the sleeve 45 may be turned in appropriate direction by means ofthe capstan holes'47 to adjust the tension of. the spring and its action, upon the arm 54. To limit the relative movement of the segments 39 and 43, a suitable stop maybe employed as for instance, the adjusting screw. 56,,one end of which. is adapted to' contact withalugv 57 projecting from .the rocking segment 39. t j- From the construction so .far described, it will be apparent that when the tack carrier slide 2'moves in a direction to deliver atack .to the-driving means, the rocking member: 34 will berocked about its pivotal connection. 35 with the tack carrier slide and the toothed segments-39 and 43 will remain in fixed positions. Should, however,"the rocking member 34 be prevented fromrocking-movement as the tack carrier slide moves to deliver a tack, it will cause rocking movement of-the segment 39in a contraclockwise directiomFig. 6, into the position indicated in Fig. 7, thereby rocking the segment 43 and perforce, turning the shaft 44 fora purpose that will presently appear; 3'. j r a The arm -54 has pivotally connected thereto, as atf58, athrust member 59, the

end 60 of which is normally pressed into a recess 61 ofan actuator 62 by the spring 50. The thrust member 59'is connectedby. a link 63 to the tack separator 64 which may be of usual construction as herein before stated; The actuator'62 is pivotally connected to the'rocking member 34, and. in the present instance of" the invention; this pivotal connection is furnished by the bolt 36 which connects the link37 to therocking member, substantially as indicated Figs. 6, 7 and 8. 1

The rocking membe'ri34 has a, toe or'pro jejction 65 which, in'the'normal operation of the, machine when a shoe is'in position 7 for the lasting operation, misses the-block 30ras the tackcarrier; slide moves therocking member during-the tacledeliveringoperation. The rocking member 34 .has another,

toe or projecting portion 66 which, under of Fig. 8, a third toe or-projection 68 on the rocking member 35- engages the actuator 62 at 69 to, return the; actuator to its initial position, asindicated in Fig 6, and effect the delivery ofaJtack. V 7

.Should, however, a shoe not be presented in lasting position for the action of the wiper as: the latter performs its wiping function, the wiper'will notbe held in its raised or wiping position, but will drop into the position, indicatedin Fig.3, thereby permitting the spring 26 to move the block 30 into the path of the toe 6,5"on the rocking member 3 5 g This contact of the. toe 65 with'the block 30 prevents rocking movement of the rocking member 34 as the tack carrier slide moves to theleft to deliver a tack to the inserting mechanism, as indi-' cated in Fig. '7, and under these conditions the link 37 will cause'the segments 39 and 43 to turn as hereinbefore described, to rock the shaft 44, for'apurpose to be presently" explained, and to prevent actuating move-- mentof the actuator 62 sufficiently to operate the tack separator 64 and the parts will then assume the position as indicated inFig. 7,, thus suspending the delivery of tacks. I I Should the tack separator 64be obstructed in its reciprocating movement during the normal operation of the machine, the thrust .member 59being held inthe seat 61of the actuator the 'spring50 will ride out of the seat 61 as the actuator performsits actuating function or swings from the position of Fig. 6 into that of Fig. 8. At such time, the end portion 60 of the thrust member. will travel along theplane surface 70 of the actuator and a breakage of parts will be prevented. I j V j From the construction thus far described as one good, practical form. of the invention,

it will be apparent that, when the wiper'per-v forms: its wiping function and detectsthe presence of a shoe in lasting position, it will hold theblock 30 out of the. path of movement of the toe 65 of the rocking member 34 as the tack carrier slide ended; carrier together with? the wiper, performtheir respective :taclnclelivering and wiping functions; but should the wiper detect the absence of a shoe from lasting position as it moves to perform its wiping function, it

will no longer prevent movement of the block80 into the path of the toe? 65 of the rocking member 34c, and the latter will therefore have its rocking movement arrested, .and be carried bodily by the tack carrier slide to the left, without imparting to the actuator 62 operative movement sufficient, to reciprocate the tackseparator 64: and a suspension of tack-delivery will therefore occur.

It may be desirable in some cases, to arrest the operation of the tack-inserting mechanism when the wiper detects the absence of a shoe from lasting position. To this end, the shaft 44 has secured to the upper portion thereof, a block 71, Fig. 1, having an arm 72 connected to a driver lock 73, the toe end 74 of which is adapted to be projected under an abutment 7 5 of the driver 10, the construction being such that when the shaft a4 is turned clockwise from the position-indicated in Fig. 6 to that of Fig. 7,at which time the wiper has detected the absence of a shoe from lasting position, the driver lock 73'will be moved into locking engagement ,withthe driver 10. Obviously, the character'of driver lock may be varied but in the present instance of the invention, it is shown as a rod mounted'for sliding movement in a guideway 76, Fig. 5, at one side of the driver bar.-

Normally the.tackdelivering means and the fastener-inserting mechanism are operative to perform their respective functions, but are arrested in the discharge of these functions when the wiper detects the absence of a shoefrom lasting position and will remain in such locked condition to suspend the deliveryand driving of tacks until the attendantplace's a shoe in lasting position, whereupon the discharge ofthe functions'of the tack delivering and driving mechanism is resumed.
