Application filed April 16, 1917.

To all whom it may concern Be it known that we, MATTHIAS BROOK and THOMAS H. Sunny, citizens of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, and Maiden, in the county of Middlesox, and State of Massachusetts, have invented certain Improvements in Machines for Operating on Shoes, 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.

The present invention relates to machines and more particularly to such machines for use in the manufacture of boots and shoes that act upon the shoe by repeated opera tions of a tool. a

In machines of the general type abovenoted, the angular relation of the tool and shoe suitable for properly effecting the purpose of the tool on one part of the shoe is not always suitable 'for the best results in treating another part of the same shoe, owing to the change in the form or contour of the shoe at the different portions treated. This fact is well exemplified in a lasting machine, for instance, wherein the upper is worked into lasted position by devices acting upon successive portions of the upper materials. These devices usually comprise pinccrs which are actuated to grip and pull the upper and lay it over the innersole, and a wiper which is caused to wipe or press the overlaid upper material smoothly upon the innersolc where it is secured in lasted position by tacks. Owing to the changing contour of the shoe along the edge or" the last or innersole, the upper materials will he fuller at some points than at others, and consequently, the angular relation of the lasting devices and edge oi? the shoe suitable to plaiting and smoothly laying the stock over the innersole at one point will be unsuitable for securing the desired result at another point.

In recognition of this, it has been pro posed, in lasting machines of this general type, to give to the pincers an axial turning movement to plait the upper material where excessive fullness of stock occurs and to move the wiper in an inclined path relative to the ed 'e of the shoe, such movements of the pincers anc wiper being etl ected by de- Specification of Letters Patent.

vices under the operators control. In such cases, the operator, while holding the startlng treadle of the machine depressed, to

continue the machine in operation, has pre- 7 sented the shoeby hand to the lasting devices, and when, in his judgment, the fullness of stock required the plaiting movements to be initiated, he could manipulate a knee-controlled lever which would cause the pincers to be turned more or less axially and the wiper to move in an inclined path over the edge of the shoe. This action as well as the extent and direction of the plaitin movements, could be continued indefinitely at the will of the operator or he might neglect them entirely, in which latter event the beneficial results sought by such manual control of the pincers and wiper would be entirely lost.

An important feature of the present invention consists in means for giving to the tool successive movements toward and from the shoe and for automatically imparting to the tool additional movements in a different direction that the angular relation of the tool and the shoe may be appropriate to the diilerent portions of the shoe treated by the tool. This characteristic of the invention may be embodied in mechanism for changing the angular direction of movement or the position of the shoe instead of the tool, and ii -many types of machines employed in the manufacture of boots and shoes, wherein a tool acts by repeated operations upon different portions of the shoe; but in the present instance of the invention it is illustrated in connection with a lasting machine having pineers and a wiper for laying: the upper materials smoothly over the innersole into lasted position by repeated operations upon successive portions of the shoe.

Where the tool is to act by repeated operations along one edge of the shoe and then along the other edge of the same shoe, the direction of angular relation between the tool and the edge of the shoe at one side should, under some conditions, be different from or opposite to the direction of angular relation between the tool and the edge of the shoe at the other side. T his is important, especially in a lasting machine of the general type hereinafter mention because the fullness of stock is more satimactorily plaited and smoothly laid if the tool moves in the proper direction. Another important feature of the invention, therefore, consists in means acting automatically to cause the tool to move in a path inclined to the median vertical plane of the machine in one direction while operating on one part of the shoe and in a path inclined in a different direction while operating on another part of the shoe. 1

Another feature of the present invention consists in means for imparting to the tool in addition to its movements toward and from the work, a predetermined number of additional movements in a different direction. Shoes differ in size, however, so that the predetermined number of additional movements given to the tool for one size of shoe may not be suitable for other sizes. In the case of a lasting machine which acts "to place the upper material in lasted position by successive operations of the lasting devices, for instance, the number of successive movements to effect the purpose of the lasting devices on a shoe of one size will not be suflicient to complete the lasting opera tion on a shoe of a larger size. Another important feature of the present invention, therefore, consists of means for varying at will the number of successive movements of the tool toward and from the shoe and automatically varying the predetermined number of additional movements in different direction that shall be imparted to the tool.

Other features of the invention, in addition to the above, including important combinations of parts and details of construction, will be hereinafter described and claimed.

In explanation of the present invention,

detail in side elevation, show section on the line 66, Fig. 5;

it is illustrated as applied to a lasting machine of the general type disclosed in the United States Letters Patent No. 584L54 dated June 15, 1897, and will be herein described as controlling the angular movements of the wiper as it is moved toward and from the work to lay the upper materials over the innersole into lasted position; and while the invention has special advantages when used for controlling the wiper movements in such machine, it may also be employed advantageously in connection with any machine for use in the manufacture of boots and shoes wherein the work is treated at different portions thereof by repeated operations of a tool.

The machine frame for supporting the operating parts of the machine may be of any usual or desired character, in the presentinstance of the invention, is shown as comprising a standard 1 in which is the telescoping support 2 carrying the head frame 3. v

Mounted on the head frame 3 is the tack pot 4 actuated by the usual gearing 5 driven from the pinion 6 which derives its motion. from any suitable driving connection, substantially as usual in this class of machines. Mounted on the head frame 3 is the raceway 7 by which thefastenings, such as tacks, or the like, may be supplied to a tack carrier S for delivery to driving position, as usual. iVhen the fastenings or tacks are de livered to driving position, they are driven into the work by a driver 9, the upper having been properly worked into lasted position prior to each driving movement of the driver. edge of the upper materials and laying them over the innersole, may be of usual construction, and operate in the usual manner, as Well understood by those skilled in "the art. Machines of this general type are usually provided with'an edge gage 11 and a shoe rest 12, whereby the shoe may be properly positioned for the lasting and tackdriving operations.

secured to the machine head 3 as by means of the bolt 13, is a support 14 which underlies the wiper l5 and serves as the sustaining means for an elongated guide 16, Fig. 4, pivoted on the support 14: for rocking move mentwith relation thereto, substantially as more fully disclosed in the patent to Bates, No. 1,029,840, dated June 18, 1912, to which reference may be had. The wiper 15 may be of the same general character as disclosed in the Bates patent, and be provided with a part as described in said patent,'for engagement with the guide 16, the said wiper being pivotally mounted as in said Bates Patent and given a reciprocating movement toward and from the work for engaging and laying the upper materials over the innersole of the shoe presented for the lasting opera The pincers 10 for gripping the.

tion. The parts so far described may be as fully disclosed in the Bates'patent, the construction being such that as the wiper 15 is moved toward and from the work, and consequently moves relatively to the guide 16 which engages the wiper at one side of its pivotal mounting, the wiper will be given an angular or inclined movement with respect to the vertical median plane of the machine or with respect to the edge of the shoe; and the degree of inclination of the guide 16 will determine the degree of inclined or angular movement thus imparted to the wiper. The guide 16 at one end thereof is pivotally connected at 17, Fig. 4, with a link 18 which is pivotally joined at 19 with one end of an operating arm 20, mounted upon a rocking member or shaft 21 which is supported in a suitable bearing 22 secured to the head frame 3, the construction being such that by rocking movement of the shaft 21, the guide 16 may be given different inclinations with respect to the su port 14.

becured to the lower end of the rock shaft 21 is an arm 23 pivotally connected at 24 to a link 25 which is connected at 26 with a block 27 mounted for sliding movement in the guide 28. The sliding relation of the block 27 with respect to the guide 28 may be effected by any suitable means, but in the present instance of the invention, the block 27 has the side projecting portions 29 which engage corresponding guideways in the guide 28, and the connection between the link 25 and the block 27 may be conveniently formed by a pin 30, Fig. 5, projecting downwardly from the block 27 The guide 28 is secured to the lower end portion of a rock shaft 31, Figs. 5 and 6, by suitable means such as the screw 32, the rock shaft being itself sustained in a suitable bearing 33 carried by an arm 34 which may be secured in fixed position to the head frame 3 by suitable means. In the present instance of the invention, the arm 34 is secured by a bolt 35 to a block 36 which may be either formed integral with or attached to the head frame 3. From the construction'thus far described, it will be apparent that should the rock shaft 31 be rocked on its axis and the block 27 be eccentrically positioned in the guide 28 with respect to the axis of the rock shaft, the guide 16. will be moved to change its angular relation on the support 14.

Secured in the block 36 is a pin or shaft 37 having mounted for rotative movement thereon a cam 38 providedwith a cam path 39 in which travels a roll 40 mounted on a pin 41, Fig. 9, carried by a crank arm 42 secured to the upper end portion of the rock shaft 31. The pin or shaft 37 may be prop erly secured in the block 36 by any appropriate means, and in the present instance of the invention, the pin or shaft 37 is provided with an enlarged head portion 43 which affords means for securing the pin or shaft in the block 36. Between the enlarged portion 43 and the cam 38, the block 36 is suitably recessed to accommodate a spring 44, one end 45 of which is secured to the enlarged portion 43 and the other end 46 of which is secured to the cam 38, the construction being such'that should the cam be rotated on the pin or shaft 37, and then be released, the spring 44 will return the cam 38 to normal position.

In order to protect the cam 38 and the cam path 39 from accumulation of dirt, the block 37 may be provided with a shield portion 47, Fig. 5, extending over the cam 38.

Mounted for rotative movement on the pin or shaft 37 is a series of ratchets 48, 49, 50 and 51, four of such ratchets being indicated in the present instance of the invention, but any appropriate number may be employed, as dictated by circumstances of use. The rotatably mounted ratchets are connected together to rotate in unison, and with the cam 38 by a pin 52 or any other suitable means which will unite the cam 38 and the ratchets for rotative movement together. Each of the ratchets 48, 49, 50 and 51 is provided with a series of teeth, the teeth of one ratchet differing in number from the teeth of the other ratchets, the construction being such that by rotation of any one of the ratchets stepby-step, the cam 38 will be given a step-by-step turning movement upon the pin or shaft 37 in accordance with the number and character of the ratchet teegh on the particular ratchet being actuate The free end portion of the pin or shaft 37 is provided with a bearing 53 for the support of a rocking member 54 which may be appropriately held upon the end of the pin or shaft 37 by securing means such as the washer 55, Fig. 5. The rocking member 54 carries a portion 56 which overlies the series of ratchets, substantially as indicated in Figs. 6 and 7, and is provided with a series of grooves or notches 57 adapted to engage with a holding pin 58 yieldingly mounted on the end portion 59 of an actuating pawl 60. The pin 58 may be conveniently sustained in a socket of the pawl 60 as indicated in Fig. 6, and be spring-impelled down wardly or toward the notches or recesses 57 in order to maintain the pawl in adjusted position, as will presently appear. The pawl 60 is mounted to rock upon a pin 61 which is carried by the rocking member 54 and is indicated in Fig. 7. The pin 61 may be secured to the rocking member 54 by any suitable means such as the screw 62 as indicated in Fig. 7, the construction being such that the pawl 60 may be moved longitudinally of the pin 61 to place its operating portion or toe 63 in operative relation with any one of the series of ratchets mounted on the pin or shaft 37; and when moved into such operative relation, the pawl 61 will be maintained in such position by means of the holding pin 58 which will engage the appropriate recess 57. The pin 58 may be under the influence of a suitable spring 64 for holding the pin in engagement with the notches 57 and the oprating toe 63 of the pawl in operative relation with the teeth of the ratchets.

The rocking member 54; is connected by a link 65 to a crank pin 66 projecting from the shaft of the pinion 6, Fig. 1, the construction being such that as the pinion 6 is turned by its actuating means as hereinbefore described, the link 65 will be reciprocated to impart to the rocking member 54: its rocking movement upon the bearing 53 of the pin or shaft 37. As the member 54: is thus rocked upon its bearing or support, it will actuate the pawl to thereby turn the ratchet with which said pawl is operatively associated for the time being and perforce, turn the cam 88.

In order that the ratchets may be held from retrograde movement as the pawl 60 moves on its inoperative stroke to engage another tooth of the ratchet with which it is associated, suitable stop or holding pawls are provided. In the present instance of the invention, there is a series of holding pawls 67, 68, 69 and 70 corresponding to the number of ratchets 48, 49, 50 and 51, the pawlholding ends being contrived to properly co-act with the teeth of the associated ratchet. The holding pawls are mounted upon a pin 71, Fig. 6, carried by an arm 72 which is mounted upon a rock shaft 7 3. In the present instance of the invention, the arm 72 is clamped to the rock shaft 73 as indicated in Fig. 6. Each of the holding pawls is provided with a spring-actuated plunger 74, Fig. 6, which normally holds the several pawls pressed toward the ratchets with which they co-act, a guiding in 75, Fig. 6, being provided for guiding the holding pawls in their movement toward and from the ratchets. The guiding pin 75 in the present instance of the invenscribed, will return the ratchets and perforce, the cam 38, to initial position. In order that this return movement of the ratchets and the cam may take effect upon the withdrawal of the holding pawls, it is desirable that the operating pawl 60 be lifted from engagement with the teeth of the ratchet with which it is operatively associated. To this end, the rock shaft 73 has one of its arms 72 provided with a lifting pin 80 which, when the ratchets are being operated by the operating pawl as indicated in Fig. 6, underlies a projection or toe 81 of the operating pawl. lVhenthe rock shaft 73 is turned to withdraw the holding pawls the pin 80 will lift the operating pawl from engagement with the ratchet teeth, thereby permitting the ratchets and cam to return to their initial position under the actuation of the spring 44; and conversely, when the rod 79 is lifted, the holding pawls and operating pawl 60 will be permitted to assume operative relation with the ratchets. The rod 79 may be the usual starting rod or the usual brake rod common in this class of machines, which, by upward movement, causes or permits the machine to start into operation, and by downward movement, brings the machine to rest.

From the construction thus far described, it will be apparent that when the machine is started by upward movement of the rod 79, the operating pawl 60 and the holding pawls will assume operative relation with respect to the ratchets, and the operating pawl 60 will impart to the ratchet with which it is operatively associated, a step-bystep movement to thereby turn the cam 38 and perforce, the rock shaft 30 and the connected guide 16 to change the angular position of the guide 16 in accordance with the contour of the cam path 39. If, for instance, the number of teeth in the ratchet with which the operating pawlis operatively associated for the time being is ten, there will be ten step-by-step movements given to the cam 38 and, under the dictates of the cam path 39, there will be an appropriate or corresponding number of-difl erent inclination given to the guide 16, to thereby change the inclination of the wiper in its successive operations toward and from the work; and these angular movements thus imparted to the wiper will be automatic and free from any uncertainty of manual control. They will likewise continue throughout a predetermined number of operations of the wiper appropriate to the size of the shoe being treated. It will be apparent that by appropriately changing the number of teeth in the ratchets which give actuation to the cam 38, the number of step-by-step movements imparted to the cam may be varied and. perforce, the predetermined number of different inclinations imparted to the wiper may be correspondingly varied to conform to the requirements of the different sizes of shoes. If, for instance, ten wiper movements are required to treat one side of a shoe of one size, the actuating pawl 60 will be placed in operative relation with the ratchet containing ten teeth; but if the size of the shoe is such that twelve wiper movements are necessary to complete the treatment of one side of a shoe, the actuating pawl 60 would be placed in operative relation with a ratchet containing twelve teeth, so that by proper adjustment of the operating pawl, and proper variation of the number of teeth in the respec tive ratchets, the wiper or other tool may be given angular or inclined movements with respect to the shoe appropriate in number to the size of the shoe, and the mechanism for thus imparting automatically to the wiper the series of movements described will be set in operation upon starting the machine.

In order that the inclination or angular movement of the tool or, wiper while acting on one part of the shoe, as for instance, along one edge thereof, shall be in one direction, and while acting upon another part of the shoe, as along the opposite edge, may be in the reverse directiomthe present invention contemplates means for changing the direction of inclination or angular movement of the tool or wiper each time the machine is started in the performance of a cycle of operations, and an appropriate means to this end will now be described.

Connected to the block 27, Fig. 2, is a link 82, the opposite end portion of which is con- .nected to a rocker 83 pivotally mounted at 84 on an arm 85 pivoted at 86 to a suitable support 87 which, in the present instance of the invention, comprises 2. lug extending from the machine head 3. The arm 85 in the present instance of the invention, is shown as bifurcated, the ends of the two arms 88 forming the bifurcation resting upon a collar 89 loosely support/ed upon the rod 79. Secured to the rod 79, as by means of the clamp 90, Fig. 3, is a sleeve 91 to which is pivoted at 92 a rocker actuator 93. The rocker actuator 93 has a bifurcated portion 94 between the sides of which is received the extension 95 projecting from the rocker 83, Fig. 3, the construction being such that should the rocker be moved upon its pivotal mounting 84, the end 95 acting in the bifurcated portion 94 of the actuator 93 will cause the latter to swing upon its pivotal mounting 92 for a purpose that will presently appear.

Pivotally mounted at 96 on the rocker actuator 93 are two rocker pawls 97 connected by a spring 97*, eachof which pawls is provided with a shoulder 98 adapted to engage shoulders 99 and 100 respectively, of the rocker 83 upon upward movement of the actuator 93. The rocker 83 carries a roller 101 which is adapted to travel in a trackway 102 formed in a block 103 secured to a fixed 9 part of the machine, which in the present instance of the invention, is the head 3. The trackway 102 in the block 103 has end portions 10% and 105 which act as stops for the travel of the roller 101 carried by the rocker, the construction being such that when the parts are in the position indicated in Figs. 2 and 3, the link 82 will maintain the block 27 at one side of the axis of the rock shaft 31, and rocking movement of said shaft through the cam and ratchets as hereinbefore described, will cause the guide 16, and perforce, the angular movement of the tool or wiper to take one direction, although the amount of angular movement or inclination of the tool or wiper in that direction may vary according to the dictates of the cam. \Vhen the rocker 83 is swung to the other position, or to the left in Fig. 3, the link 82 will move the block 27 to the opposite side of the axis of the rock shaft 31 so that the angular movement of the guide 16 and perforce the angular movement or inclination of the tool or wiper will be in a direction opposite to that which it before had.

From the constructipn described, it will be apparent that upon upward movement of the rod 79 against the action of the spring 106, which is interposed between the loose collar 89 and the fixed sleeve 91, the rocker actuator 93 will be raised, and, when the parts are in position indicated in Fig. 3, the shoulder 98 of the pawl 97 will engage the shoulder 100 of the rocker and, by continued upward movement of the rocker actuator 93,,

will cause the rocker to be swung about its pivot 84 into its opposite position with the roller 101 seated against the stop 101 of the trackway 102, and such movement of the rocker will act through the link 82 to shift the position of the b ock 27 in the guide 28 as hereinbefore described. As the rocker is thus shifted, it will throw the actuator 93 to the right from the position shown in Fig. 3, so that when the rod 79 is allowed to descend after a series of repeated operations by the tool or wiper, the shoulder 98 of the lefthand pawl 97 will engage beneath the shoulder 99 of the rocker 83 ready to swing the rocker 83 back to its former position when the rod 79 is again lifted. Thus it will be noted that upon successive starting actions of the machine, the tool or wiper will first be caused to act during a seriesv of operations in angu ar relation to the median vertical plane of the machine or shoe edge in one direction, and will then be caused to act for a corresponding, series of successive operations in the opposite direction.

The character of the cam 38, as well as the number of teeth on the ratchets may be varied to suit the particular, conditions of use, but when employed in a lasting machine of the general type hereinbefore referred to;

it has been found thatfour ratchets each with a different number of'teeth from the other, will be ordinarily sufficient to complete the lasting operation along the sides of shoes of different sizes.
