LASTING-MACHINE.

Patented Dec. 17, 1918.

Application filed September 16, 1918. Serial No. 790,003;

7 '0 all whom it may concern:

Be it known that I, CHARLES F. PYM, a subject of the King of Great Britain, residingat Detroit, county of Wayne, State of Michigan. have invented an Improvement in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to lasting machines for use in the manufacture of boots and shoes, and has for its object to provide a simple machine, operating on a novel principle, and capable of great speed and high efiiciency.

Heretofore lasting machines have been either of the hand-method type, employing pincers which were reciprocated toward and from the shoe to embrace, grip and pull the upper leather about the wood of the last; or of the wiper type, which employed a wiping plate or plates to smooth, strain, or wipe the upper into place over the bottom of the last. The pincer machines are most eflicient in operating on the sides of the shoe, whereas the wiper type are found to be more advantageous in lasting the heel seat and toe portions of the shoe. My present invention enables me to provide a machine utilizing the advantageous features of both the hand method and the wiper type,

"and furthermore securing the advantages of a gripping pull on the upper around the forepart, together with a wiping action on the toe and heel part. Moreover, I secure these twofold advantages by means of the same instrumentalities, z. e. combined positively gripping and wiping means. This feature is a distinct novelty in the art of lasting boots and shoes, and I therefore wish to claim the same broadly.

The hand method type of machine using grippers is somewhat limited as to speed of operation because of the complex movements of the pincers which are first moved downwardly toward the'shoe to be in position about the upper leather, then are closed,

then are moved upwardly to exert a vertical operation while securing a satisfactorily positive grip and pull on the upper. The

lasting type, depend upon a wiping action to last the upper, and 1f grippers are also employed, as 1n my Patent 865,936, they valso were moved vertically and were independent of the wiping action and are relatively slow in their gripping action. My present invention utilizes gripping jaws which exert a horizontal, as distinguished from a vertical or-upward, pulling action on the leather, gripping the projectlng edge portions of the upper leather directly at the edge of the last and on a minimum of projecting material. templates lasting by grippers, in a power actuated machine capable of running at high speed, utilizing a wiping grip and combining therewith a wiping action like the machines of my prior patents above mentioned, whereby I am enabled simultaneously to both pull and wipe the upper leather over the edge portion of the last and preferably by the same instrumentalities, i. e. by combined gripping and wiping means.

The machine of my present invention in its novel operation of securing a substantially horizontal wiping-grip on the upper leather, will operate with equal accuracy, whether the upper leather is cut full or scant, gripping the edge portion of the upper. whether it projects but little or considerably above the edge of the last. whereas formerly great difiiculty was experienced in lasting machines employing grippers because often suflicient upper material would not project above the last to give the grippers a hold. This was especially true in case the upper was cut scant and consequently the machine grippers failed to (act, and uppers of this sort had to be lasted by hand. If uppers are cut with fullness to enable the grippers to secure the proper hold the extra material has subsequently to be trimmed 0d,

My invention thus con-- necessitating a considerable waste of upper leather, whereas in my present type of lasting machine, such a waste of material is obviated. This advantage results from my 5 invention largely because it utilizes.a substantially horizontal pull or wiping grip on a the edge portion of the leather, as distinguishcd from a substantially vertical pull and grippers to exert such a vertical pull, This horizontal wiping grip, furthermore, is effected by instrumentalities which produce the gripping pull with an upwardly straining action on the leather, thus constantly tending to tighten the leather against the wood of the last and counteracting any slippage of the leather inthe grippers. The grippers, or one of the gripper members, are arranged to swing in an arc with the lowest point of said are at the edge of-the last and will therefore give an increasing tightening or upwardly straining pull upon the leather gripped, and offset any slipping of the leather through the grippers during the continued swing of the gripper or grippers in said are.

Another feature of importance in my present invention is that I provide mechanism capable of rapid use in lasting the side and toe portions of the shoe by positively gripping and pulling the leather, and which with equal facility, will last and form the heel seat of the shoe, with the additional advantages incident to a wiping action at the heel seat, enabling the operator to go entirely around the shoe bottom in the lasting process and complete this operation both on the forepart and around the heel with asingle machine. Thus an operator with a single handling of the shoe, while it is in 40 position, can complete the lasting of the forepart and formation of the heel seat, by means of instrumentalities peculiarly advantageous for each operation. Preferably I arrange the grippers which constitute the 45 combined pulling and'wiping. means for lasting the shoe, to be reciprocated in a definite vertical plane extending from front to rear of the machine and the operator may hold the shoe with the adjacent portions of its edge either at right angles to this plane of reciprocation or at any desired angle thereto, .as in going around the toe, for example, to facilitate the pulling of the upper and plaiting of the upper material about the curved contour of the toe. As the pulling and wiping grippers move at high speed. approximately at the rate of 2000 movements per minute, my lasting machine produces a progressively continuous pulling action on the upper leather, and thus eliminates all chance for wrinkles or unevennesses in the leather as it is wiped, pulled and stretched over the edge of the last, either along the sides or at the toe and heel of the 6 shoe. My present machine is capable of a higher speedof operation than any power gripper-lasting mechanism, and this high speed, combined with the positive gripping and wiping action, each gri ping action overlapping the preceding, e ects substantially continuous pulling of the leather, which is a distinct novelty in the lasting art, and which I wish to claim broadly.

In the preferred embodiment of my invention as herein shown, I employ a positively actuated, horizontally reciprocating wiper member which cooperates with a movable grip-ping device, yieldingly held toward the wiper member and together constituting the grippers which grip and pull the leather during the forward or wiping movement of the wiper member. In a modified form I show the wiping member as cooperating with and actuated simultaneously with the members which are structurally separate from the: wiper, and in each form the lasting action is accompanied by a. simultaneous wiping andpulling of the leather in a substantially horizontal line as distinguished from prior lasting devices which pulled the leather in a vertical direction. The cooperating gripping devices, whether a single member acting with the forward end of the wiper or a pair of grippers acting in combination with the wiper, may have a pivotal action, but this will simply tighten their hold upon the leather and does not pull the same vertically, while it does tend to exert a slight upward straining or'swinging tension. To facilitate the use of my improved lasting machine for operating entirely around the shoe including the sides, toe part and heel, I preferably arrange suitable guides, one for use around the "we or heel, and the other for the sides and shank of the shoe, one of the guides being adapted to be quickly swung into or out of operative position and when in its inoperative position to expose the other guide for use.

The terms positive and positively as used in this specification in connection with the gripping of the upper against the wiper are used to designate an actual grasping and pulling of the leather as distinguished from 115 a mere wiping action. it being understood, of course. that as the stretch is removed from the leather by the constantly repeated pulls, there will be more and more slipping of the leather between the gripping surfaces. 12C

Other features of the invention, novel combinations of parts, and details of description will be hereinafter more fully pointed out and claimed,

Referring to the drawings.

Figure 1 is a side view of a preferred embodiment of the invention, wherein a type of wiping-gripper comprising a single gripping member coopera-ting with the wiper member is illustrated;

aasaeeo Fig. 5 is a plan view of the form of wiping gripper shown in Figs. 1, 3, and 4.

In the embodiments of the invention shown in the drawings, I have used, for illustrative purposes, a lasting machine of the type shown in my prior Patent, 881441, to which patent reference may be made for the details of construction, operation of the wiping and tacking mechanisms, ar-

rangement and timing of the cams, clutch, etc. The machine may be suitably mounted on a pedestal 1,-and comprises a head 2 having a slideway 3 in its forward portion to contain a vertically reciprocable bar 4, carrying the tack driver operating in the nozzle 5 and actuated by a lever 6, which lever is pivoted to the head 2 at 7 and is rocked by an appropriate cam connected by a single revolution, treadle-controlled clutch as in said Patent'No. 881,441 to a continu-' ously running pulley on a shaft 8 which is mounted in bearings at the rear of the machine. A wiper bar 9 is pivoted at 10 to the upper end of a link 11 which has its other end pivoted at 12 to a rigid bracket 13, affixed to the head 2, said wiper being arranged for endwise reciprocating and oscillating movement with and about pivot 10 in a vertical plane extending from front to rear of the machine. This motion is derived from an eccentric 14 on a shaft 15 adjacent the cam shaft 8 at the rear of the machine; The driving pulley is geared to shaft 15, as shown in Fig. 1. to cause the latter to run at a relatively high speed. both shafts being rotated from any suitable source of power. The forward portion of the wiper bar 9 will, by said eccentricand link, thus be given a movement in a substantially elliptical path which. when a shoe is in position to be rubbed, will comprise aforward stroke in a nearly horizontal plane in rubbing contact with the upper, a slight lift and a return stroke out of contact with the shoe. as fully explained in my said Patents 880,401 and 881,441. The forward or operating portion of the wiper 9 comprises a forked wiping plate 16. Fig. 5. pivoted at 17 in a suitactuated by a link 21, which presser is also forked at 22 to straddle the tack nozzle 5.

and fits within the forked plate 16 of the wiper bar, as' also shown in my said patent, although the use of such presser is ontirely optional.

To cooperate with the wiper plate 16 and to constitute a wiping gripper, and therefore to provide means to positively grip. hold and pull the leather of the shoe during the wiping action, I provide a jaw 23 pivoted or otherwise movably held to any suitable part of the head 2, as on a pin 24, see Figs. 1 and 3, supported between flanges 25 and 26 formed on the forward portion of the slideway 3. The lower end 30 of the jaw 23 is preferably made so as to cooperate with the end of either of the forks of the plate16, to facilitate lasting on either side of the shoe, 2'. e. from left to right of the machine, or from right to left,'and in order to readily adjust the jaw 23 to coiiperate with either of said forks of the plate 16. the flanges 25 and 26.are spaced apart and an intermediate guide 27 (see Fig. 3) is formed, so that the bar 23 may be held in position to cotiperate with either fork of the wiper 16. When it is desired to last a shoe by moving'it from right to left, view-- ing Fig.3, the jaw 23 will be fitted between the guide 27 and the outer flange 26 by simply sliding it along the rod 24 to the position shown in Fig. 3, then the end 30 of the jaw 23 and the right hand fork of the wiper 16 will cooperate to last a portion of the shoe upper prior to the driving of the tack. In order to arrange the jaw 23 to cooperate with the other fork of the wiping'plate 16 to last a shoe being drawn from left to right viewing Fig. 3, it is only necessary to lift the jaw 23 and slide it on the rod 24 to position between the guide 27 and left hand flange 25. A U-shaped spring 28 is fitted about the end portions of the rod 24 with its inner ends bearing upon stops 29 and its U-shaped por tion across the bar 23, so that the same will be held yieldingly with its lower end 30 in position to cotiperate with either fork of the plate 16 as already explained. An adjustable stop 31 is threaded through the bar 23 so as to limit the closing movement of the jaw 23 relatively to the wiper 16 as the latter is retracted and thus to permit a feeding of the shoe by the operator.

In order to provide a suitable work rest for the side of the shoe being operated upon, the bracket 13 is fitted with a slideway 32 in which the shank 33 of a carrier 34 is adjustably secured, said carrier having provision to support a rotary work rest 35, similar to that illustrated in my Patent 881,441, and a straight edged work rest 36.

for use in Iastingaround the heel and toe i the shoe.

,. preferably projecting slightly forward of the rest 36 as clearly shown in Figs. ,1 and 2.

The operation of my improved machine and the production of a wiping grip will, it is believed. be readily understood. During the operation of the mechanism, the wiper bar 9 as it is reciprocated to and fro in its wiping action, will cause the forks of the plate 16 to engage the leather of the upper with their ends 40, one of which during its continued forwardly wiping action will press the leather so engaged against the cooperating end portion 30 of the jaw 23, thus effecting a gripping action, which grip is initiated by the single forward wiping movement of the wiper. When the leather is thus gripped, the continued wiping action of the forks 40 will not only wipe, but pull the leather of the shoe firmly and positively to the completion of their forward wiping action. If it is desired to secure a more nearly positive gri upon the upper, either or both gripping surfaces of the jaw 30 and the forks 40 may be corrugated. Any suitable controlling means may be utilized for causing the tacking mechanism to drive a tack automatically after as many wiping gripping actions of the wiper mechanism as is desirable or, as shown in my said Patent 881,441, at the will of the operator. As the wiping plate 16 is given a slight orbital action during its horizontal reciprocations, due to the link 11 and. eccentric 14,the-grippi'ng portion 30 of the jaw 23 will secure its gripping hold slightly under the cooperating edge 40 of the wiper 16 and a close grip is thus obtained directly at the edge of the last, so that the shoe upper may be cut scant and still will be gripped and pulled by my wiping gripper as above explained. This wiping grip not only pulls and smooths the leather, but does so in a substantially single action and in a single line of movement, 2'. e. in a substantially horizontal line; the leather engaging, leather gripping and leather pulling actions, all being substantially components of the forward or wiping movement of the mechanism, thus produce a most effective wiping and gripping or combined wiper-gripping action. Moreover, the wiping grip may be only enough to apply a relatively light pullto the upper, well within what the particular upper stock can safely bear, and yet the constant rapid repetition of the light pull produces a greaterlasting effect than could possibly be secured by a single powerful pull without injuring the upper.

I have illustrated in Fig. 2 a modified form of wiping-gripper, wherein a similar wiper bar 41 is provided to effect the wiping and pressing of the upper leather, together with independent cooperating gripper jaws 42 and 43, which gripper jaws effect the gripping of the leather and are given a pulling action in combination with the independent lasting action of the wiper, 41. In this construction, the gripping and wiping areefi'ected by different mechanisms, but the gripping and wiping are component portionsof a wiping gripping, lasting movement, effected substantially simultaneously. The jaws 42 and 43 may be suitably actuated by the movement of the wiper bar 41 and I have so shown them. The jaws 42 and 43 are illustrated in Fig. 2 as pivoted at 44,

the jaw 42 having an extension 45, with its outer end pivotally connected at 46 to alink 47, which link has its other end pivotally attached at 48 to the wiper bar 41. The jaw 43 is formed with an extension 49 pivoted at 50 to a bar 51, which bar in turn is pivoted at 52 to the head 2. A spring53 is arranged to bear on the bar 51 and normally hold the same downwardly with its rear end against a stop pin 54. During the operation of the wiper bar 41 as the same is given its horizontal reciprocation, the jaws 42 and 43 will be first closed to grip the upper leather and then actuated to pull it as the wiper 41 is with the single jaw 23 cooperating with the wiper bar itself and with a similar result.

It will thus be seen that I have provided a lasting machine operating on a novel principle and capable of running at exceptionally high speed, causing the upper pulling movements to follow each other in such rapid succession that the upper is unable to recover itself between pulls and is by successive increments pulled into lasted position. It is broadly new to provide lasting means which grip the upper and operate at sufficiently high speed to eifect a substantially continuous pullin action on the upper; such continuous pu lin being also carried on progressively around the entire shoe bottom including the heel, being preferably efi'ected at substantially a ri ht angle to the portion of the edge of the ast, which forself constitutes a novel lasting means. The

combination of a positive grippin strain on the upper with a wipm action as never before been accomplishe so far as I am I aware, and this feature, while capable of operation at sufiiciently high speed to efiect a substantially continuous pulling, may of course be independently employed in any .machine, particularly in a machine of the I have coined the phrase wiping-gripper to define m combined gripping and wi ing device. his phrase also designates t e means employing the novel principle embodied in my machine, whereby the upper is lasted by a substanbed lasting type.

tially single movement; 2'. e., by a lasting de-.

vice positively engaging the leather, wiping the leather over the last edge, gripping the leather,-and then pulling and lasting it by positively straining and stretchin the leather, all in one forward motion. referably this single movement whereby the several functions above noted are accom lished, is in a substantially straight line, a thou h of course it may be in a curved line, 't e important feature being that these several motions are performed as a single movement and almost instantaneously. This is of special importance in distinguishing from the old style lasting machines using grippers to which were imparted three, four, or more distinct successive movements, viz., moving toward the leather, closing on the leather, pulling upwardly, and then pulling inwardly, as well as distinguishing from the prior bed-lasting type of machine using wipers which simply wiped or slid across the leather without positivelygripping and stretching.

In a lasting machine, means constructed and arranged to engage the upper at the edge of the last and to wipe the upper inwardly when the shoe is held in proper lasting position with relation to the machine, and means for rapidly reciprocating said wiper with a speed causing said wiping actions to follow each other in such quick succession that the upper is prevented from recovering itself between the wiping actions and is gradually forced into fully lasted position by a succession of stretching in crements,said mechanism including means to maintain the wiper in sliding contact with the upper from the edge of the shoe bottom inwardly and out of contact with the upper during its backward reciprocatory stroke combined with means between which and the wiper the upper is gripped and which is thereafter moved with the wiper to effect a pulling of the upper supplemental to the wiping.

55. In a step by step lasting machine, the combination with a reciprocating wiper of a member arranged in the path'of the wiper and movable by the wiper in the direction of its wiping movement and between which member and the end of the wiper the upper is gripped to effect a pull on the stock in addition to and during the wiping of the upper over the shoe bottom.

56,. In a step by step lasting machine, the combination with a wiper having an orbital path of movement carrying it inward over the shoe bottom in Wipin contact With'the upper and thence upward y and backwardly out of dragging engagement with the overwiped stock, of a resilently mounted member located in thep-ath of the Wiper and arranged to engage the inner side of the stock while the wiper engages the outer side and cooperating therewith to pull the. stock over the last while it is being wiped by the Wiper.

57. In a machine of the class described,
