FASTENING-INSERTENG MACHINE.

Application filed August 2-9, 1921. Serial No. 496,200.

To all 2071 0112. it may concern:

Be it known that we, Guonsn Gunno and Flinn .L. Macnnnzrn, citizens of the United States, residing at l-Vinchester, in the county of ldiddlesex, and Beverly, in the county of Essex, respectively, and State of Massachusetts, have invented certain Improvements in Fastening-Inserting Machines, of which the following description, in con nection with the accompanying drawings, is a specification, like reference character on the drawings indicating like parts in the several figures.

This invention relates to shoe machinery, for example to such machines as are used for inserting fast-enings, and has for its ob ject to provide improved mechanism for varying the operation of such machines on the work, as may frequently be rendered necessary or desirable by dissimilarity in character of the separate pieces of work operated upon or of different parts of the same piece of work.

The invention will be hereinafter de scribed, by way of example, as applied to a machine for inserting loose nails of the type disclosed in United States Letters Patent to Fred L. Mackenzie No. 1,262,820, granted April 18, 1918. Inorder to adapt machines of that type for operation on pieces of shoe stock of different thicknesses or on stock which varies in thickness at the points where different nails are inserted,

the racowa s of such machines are former with a plurality of slots adapted to contain nails of different lengths, and means are provided for causing nails of relatively great length to be supplied to the fastening inserting mechanism for insertion into relatively thick stock and for causing nails of less length to be supplied to the fastening inserting mechanism when relatively thin stock is being operated upon. The coi1- ditiens which require change in the length of the nails being inseted also frequently make necessary a change in the position of the gage by which the work is guided in the operation f such machines. For example. when nailing around the edge of the select a shoe, the thickness of the stock through which the nails are driven is frequently greater at the forepar' tlnzn in the shank by reason, for instance, of the interposition of a half sole or tap between the outsole and insole at the forepart. Consequently, it is advisable to insert a longer nail in the forepart than in the shank. The edge of the outsole also frequently projects farther beyond the edge of the insole at the forepart than in the shank, for which reason the edge gage should preferably be moved away from the plane of operationof the fastening inserting mechanism upon the initiation of the insertion of long nails to cause the row of nails to be spaced farther from the edge of the shoe at the forepart than in. the shank.

It is, accordingly, an object of the invention to provide improved means for varying the performance of an operation in the -manufacture of shoes in accordance with,

or under the control of, variation in the shoe part or parts upon which the operation is performed. Thus an embodiment of the invention, for example in a fastening inserting machine, may comprise means for cont-rolling the relative position of the gage and the fastening inserting instrumentalities of the machine arranged to vary the spacing of the row of fastenings from the edge of the work in accordance with a physical characteristic of the Work. The illustrated machine is provided with a double raceway which is shifted simultaneously with the gage by mechanism controlled by the thickness of the work to cause the row of nails to be spaced at a variable distance from the edge of the work, both the length of the nails and the distance of the row of nails from the edge of the work being thus cont-rolled by the thickness of the sole of the shoes operated on by the machine.

Since the illustrated machine is particularly designed for use in all-round nailing in the manufacture of nailed shoes, it is so arranged that the shorter nails which are inserted in the shank portion of the shoe are located nearer the edge than the longer nails which are inserted in the thicker forepart of the shoe and which it is desirable to have spaced further from the edge to permit the use of a so-called extension sole This application is a continuation in part of an application having Serial Yov 270,502, filed January 10, 1919 by George (ioddu and Fred L. Mackenzie upon which United States Letters Patent No. 1,399,765 were granted Dee. 1.3, 1921.

Although the invention will hereinatter be described as embodied in a machine for inserting loose nails. it is recognized that the use of the invention is not restricted thereto but that the invention in some of its aspects may ha e other applications including incorporation in machines oi other types than 'tastening inserting machines. Moreover, the illustrated mechanism may be materially moditied without departing trom the scope ot the invention as detined in the claims.

Other objects and Features ot the invention will appear as the description proceeds and will be pointed out in the appended claims. in the drawings,

Arm 185 of lever 82 is provided with a segment 2% meshing with a rack fill-l mounted upon slide 250 so that oscillation of lever 18: causes reciprmration ot the double pawl .302. Lever 182 also carries a cam roll which enters a cam groove in cam 4:8 upon the shaft 20 of the machine. The connections between the slide iltl-t and the double raceway Bilt, which has two slots designed to receive relatively long and short nails rtaipcctively, comprise. as shown in the patent to Mackenzie ahove meutionml, oppositely threaded rods llthl and tilt) conucctml by an adjusting nut 51:3. the rod aos being pivotally connected to the lug Ill-t upon the side oi the double raceway.

The shitting movement of the slide Iltl-lis: sutlicient to turn the eccentric upon shaft 2118 around from one dead center to the other with respect to the rod flit) so that the raceway is positively shi't'ted and positively held in either o't its positions Pawl tipper 606, arranged to operate double pawl 502, comprises two arms 608, 610 which carry respectively the dogs 536, 538 and a circular body portion provided with a hub mounted to turn freely upon a shatt 614. The body portion of the tipper 606 is cut away below its hub to form a. segmental opening 616 through which projects a stop 618 carried by an arm (320 provided with a hub sleeved upon the hub of the pawl. tipper, said arm being given a tendeney to turn in a counter clockwise direc tion (Fig. 2) by a spring 622 coiled about the hub and hearing at one end against a pin G24: upon said arm 620, and at its other end being attached to a clamp collar (326 clamped upon the hub of the pawl tipper. The movement of: the arm 620 relative to the pawl tipper 606 is limited in the direction in which the spring tends to turn said arm by a stop 628 (Figs. 2 and 3) adjustable about the periphery of the circular body portion of the tipper.

The pawl tippcr is so arranged that it is normally in short nail position, being yieldingly maintained in this position by a spring 636 which is connected at one call to a screw or stud 63S upon bracket 279 by which the raceway shitting mechanism is carried, and having its other end bent down so that it enters a socket 640 in the outer face of a bell crank lever 642 fulcrumed upon a stud 644 and havin at its forward end a short rack 646 whic engages teeth 648 in the periphery of the circular body portion of the pawl tipper 606. Between the stud 644 and the pawl tipper 606 the arm of bell crank 642 is provided with an opening which receives a stud 650 servin as a stop for the vertical movement 0 said arm, the opening being larger in diameter than the stud 650 whereby movement of the arm sufficient to rock or permit the rock ing of the pawl tipper between its two pawl tipping positions cantake place.

The pawl tipper may be moved into its long nail position either by manual means or automatically in accordance with the de mands of the work. The means for effecting the movement of the pawl tipper automatically in accordance with changes in the thickness of the work are operated through connections with the horn 22 or other work support, said'connections comprising a twopart lever 464, 468 (Fig. 1) adapted to be put into operative position by a treadle op erated cam 476, as more fully described in United States Letters Patent to George Goddu No. 1,011,941, granted December 19,

1911, a toggle 168, 170 normally maintained in straightened position whereby the pressure of a spring 164 is transmitted to the horn 22 to clamp the work against the work abutment 266, and a rod 160 connected at its lower end to pawl carrying slide 162 and at its upper end to one end of a lever 652 (Fig. 4) fulcrumed upon a short shaft 654 in the machine frame, said lever having an arm 656 provided at its end with a rack segment 658 (see Fig. 3). Therack segment 658 meshes with the small rack segment or part of apinion 660 forming part of multiplying connections carried upon a shaft 662 journaled in the machine frame, the other part of said connections comprising a rack segment 664 formed upon an arc of a circle of a larger radius than the radius of curvature of the rack or pinion 660. The rack 664 meshes with a pinion 666 carried upon the inner end of the rock shaft 614 whereby said shaft is turned as the thickness of the work gaged between the horn 22 and the work abutment 266 varies. Formed integral with the shaft 614 is an enlargedportion 668 carrying a tooth or stop 670 adapted to engage the stop 618 upon the arm 620. Thus horn 22 1s operated to measure the work, the measurement being transmitted to rod 160 and lever 652 and being utilized to control the pos tion of tipper 606 and hence to control the fastening inserting and, as hereinafter ex plained, the position of gage 8. i

It will be noted that the connections from the horn 22 to the pawl tipper operating means are of a nature such that the pawl tipper operating means does not partake of the movement of the horn to permit the work to be fed but is moved only upon change in the thickness of the work engaged by the horn.

As already indicated, the connection between the pawl tipper or actuator controlling means and the horn is normally broken between the stop 670 on the shaft 614 and the stop 618 upon the arm 620. The broken connection between the pawl tipper and the horn permits the pawl tipper to be normally maintained in fixed position by the spring 636 regardless of changes in the thickness of the work being operated upon so long as the work does not exceed a predetern'iined nection between the pawl tipper and thehorn. The stop 618 is free to move away from the stop 628 upon the circular body portion of the pawl tipper 606 but the hub of the arm 620, which carries the stop 618, is connected to the hub of the pawl tipper 606 by the spring 622 which is put under increased tension as the stop 670 tends to move the stop 618 away from the stop 628. The pawl tipper 606 is thus caused to follow the movement of the stop 618 until it comes into its long nail position, or until its movcment is limited by the engagement of one side of the opening in the arm 642 with the stud 650. If the increase in thickness of the stock is greater than that required to effect this movement of the pawl tipper, the arm 620 will move out of engagement with the stop 628, the increased tension of the spring tending to hold the pawl tipper steady in its long nail position.

If it isdesired to shift the raceway manually, this may be done by depressing treadle 706, which operates through connections 692, 682, 680 (Figs. 1 and 2) to rock lever 642 and thus to shift the pawl tipper, as more fully explained in the Mackenzie Patent No. 1,262,820.

The illustrated machine is provided with an edge gage automatically shiftable in accordance with the shifting of the raceway, so as to cause the insertion of short nails comparatively near the edge of the work, as in the shank of a shoe, and long nails further from the edge of the work, as in the forepart of a shoe provided with a half sole or tap in addition to its outsole, as will i ment on a bracket 800 carried by the machine frame is a gage member or slide 802 having a spring tltli connected thereto and tending to move the gage rearwardly. A set screw Silt; disposed to engage a. pin e08 depending from the slide :uljustably limits the movement of the gage in such direction.

To the end that the gage may be auto matically moved from one gaging position to another, the slide bar 30 i is extended bc yond the rack 2330 as indicated at 809 and has secured in its end a stud 810 grooved to receive the hooked end of a link 812 joined to the upper end of a lever 8H fulcrumed at 816 to an upwardly extending portion hi8 of the ln'acket 800. The lever trll-flis provided at its lower end with teeth meshing with a pinion $20 on a shaft iournaltal in the bracket d and formed with an eccentric portion Silt engaging :1 lug 826 on the gage slide and operable upon angular movement of the shaft 852'" to move the gage forwardly in opposition to the spring Sill. A spring 828 connected at one end to a pin 30 on the link 812 and at its other end to the pin 832 retains the link H12 in engagement with the stud. 810 but permits it to be readily detached from the stud when desired. The arrangement of the above described parts is such that when the bar 30% is moved in a direction to shift the raceway to short nail position, the extension 809 of the bar, through its connections with the gage, moves it forwardly against the resistance of the spring 804. lVhen, on the other hand, the bar 30% is moved in the opposite direction so as to eii'ect movement of the raceway to a. position to deliver long nails, the shaft 822 is rotated to withdraw its cccentric portion whereupon the gage is moved back by the spring.
