FASTENING-INSERTING MACHINE.

Specification of Letters Patent.

Patented Feb. 15, 1921.

T 0 all whom it may concern Be it known that I, GEORGE GroDDU, a citi- Zen of the United States, residing at WVinchester, in the county of h Iiddlesex and State of Massachusetts, have invented certain Improvements in Fastening-Inserting 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 machines for inserting fastenings in boots and shoes, and more particularly to fastening inserting machines in which provision is made for varying the spacing between fastenings inserted by the inserting mechanism.

In one type of machine used forthe purfastenings, the construction comprises a laterally movable head provided with guideways in which the awl and driver bars, respectively, are vertically arrangement being such that the awl is first depressed to penetrate the stock, the head moved laterally while the awl is still in engagement with the stock to feed the same, the awl then withdrawn and the head moved laterally back to its original position to bring the driver into position over the opening previously made in the stock by theawl, and finally a fastening is supplied and driven by the driver into i The driver is then raised thus completing the cycle of operation. In such a construction, it is occasionally necessary or desirable to adjust the awl with respect to the driver in order to vary the spacing between fastenings. Inasmuch as the hori zontal distance between the awl and the driver must be exactly equal to the length of the feeding stroke of the movable head, adjustment of the awl with respect to the driver must be followed by a corresponding adjustment in the connections by which the reciprocatory movement of the head is effected. Heretofore it has been necessary, in all the practical machines with which applicant is familiar, to adjust the awl with respect to the driver and then, by separate and distinct means, effect a corresponding adjustment in the movements of the reciprocatory head. Inasmuch as these adjust inents must be made with a fine. degree of accuracy, more skill is required than is usually displayed by the average operative in a shoe factory who is a shoe worker rather than a machinist. In any case, the time required to make the necessary adjust ments is prohibitive when it is desired to change the spacing between fastenings frequently as in repair work.

Accordingly it is an object of the present invention to provide improved means for effecting adjustment of the awl with respect to the driver and simultaneously corresponding adjustment in-the extent of feeding movement of the awl. By the improved mechanism thus provided, any operative can adjust his machine to vary the spacing between'fastenings and that with such a degree of ease and accuracy as to render the machine quickly adaptable to a wide range of work. Preferably the said means is so constructed as to be comprised in a unitary structure arranged for sliding movement with respect to the inserting mechanism.

It is a further object of the invention to provide improved means for adjusting the awl with respect to the driver of such a character as will be especially simple in con struction and efficient in operation. In the illustrative construction the said means comprises member mounted preferably on the awl carrier,.for ready adjustment along a path substantially parallel to the direction of penetrative movement of the awl for adjusting the awl relatively to the driver.

Other features of novelty which contribute to the carrying out of objects of the invention hereinbefore enumerated or of other obects of the invention which will be apparent from a consideration of the disclosure of the invention in the specification and drawings will be pointed out in the following detailed description and included in the claims.

In the drawings,

For the purpose of illustration the invention is shown as embodied in a fastening inserting machine of the type disclosed in the patent to Goddu, No. 490,624, granted January 24, 1893, to which reference should be had for a fuller disclosure of the fastenlng inserting mechanism. In the drawings, the fastening inserting mechanism is shown as carried upon a head 8 which is mounted upon the machine frame 9 for os illation laterally and in a direction parallel to the plane defined by the driver 10 and the awl 12. A guideway 14 is provided in the head 8 for the driver bar 16, the latter being lifted by the cam 18 and given its operative stroke through the lever 20 under the action of spring 22. Pivoted to the head 8 at the point 24 is an awl bar carrier 26 having formed therein a guideway 28 for the awl bar 30which carries the awl 12. Provision is made for adjustably mounting the awl on the awl bar by means of a block 32 arranged to be adjustably clamped to the awl bar to secure the awl selectively in any one of a plurality of positions with respect to the lower end of the awl bar, so that the awl may be adjusted toward or from the driver. Mounted upon a shaft 34, which. has hearing in the machine frame, is a lever 36 having a rack 38 at its end arranged to mesh with a rack 40 at the upper end of the awl bar to give the latter positive reciprocation toward and from the work carried by the horn 42. Extending" laterally from the head 8 is an arm 44 slotted as at 46 to receive slidably a block 48 mounted on a second block 50 in turn mounted to s ide in the guideway 52 of an arm 54 fixedly attached to the shaft 56 mounted in. the machine frame, said shaft carrying at its opposite end a lever 58 provided with a roll 60 running in a cam slot in cam 62 on the main shaft. It wi l be obvious that upon rocking the shaft 56 the head 8 will. be oscillated and that the extent of this oscillation may be varied by adjusting the connecting; b ocks 50 and 48 in their respective guideways in the arm 54 and in the arm 44 of the head 8. Theseblocks 48 and 50 are secured in adjusted position by means of the set screw member 64 which has a screw threaded portion to coiiperate with the interiorly screw threaded portion of block 50. Thus member 64'by exerting pressure onthe bot om of the s ideway 52 causes the block 50 fric tionally to ena'aqe the walls of the slideway to be he d fixedl in adiusted position. As shown in Fig. 4, the length of the member 64 from the collar 65to the end which engages the floor of the guideway is slightly greater than the dimension of block 50 along the plane of section, thus permitting the end of member 64 to engage the slotted face of the arm 54 to cause frictional engagemcnt of block 50 in the slideway before collar 65 contacts with the end of block 50. Mounted upon the outer end of the securing member 64 is another block 66 arranged to slide in a slot 68 in the awl bar carrier 26. Thus when the blocks 48 and 50 are adjusted vertically in their respective guideways the block 66 is moved at the same time and to the same extent along its guideway in the awl bar carrier 26.

In the operation of the machine, the awl 12 is first depressed to cause it to penetrate the work, after which while the awl remains in the work the head 8 and awl carrier 26 are swung to the left on the machine frame, as seen in Fig. 1, by the arm 54 and blocks 48, 66 to feed the work. Upon the termination of the'movementof the head 8 to the left, the awl is Withdrawn from the work, and the head 8 is swung back to its original position in order to bring the driver over the opening madein the work by the awl. The driver is then forced downwardly to in sert a fastening into the work, after which it is again raised, thus completing: a cycle of operations of the machine. When the driver is in driving position, as shown in Fig. 1, both the guideway'52 in the arm 54 and the slot 46 in the arm 44 of the swinging head 8 are vertically disposed. Conse quently. if the blocks 48 and 50 are adjusted upwardly or downwardly in the slot 46 and guideway 52 respectively, the path of moveient of the driver in inserting a fastening into the. work. or, in other words, the line of drive of the fastenings will not be aflected. it is manifest, however, that if the blocks 48 and 50 are adjusted upwardly, the range of movement of the swinging head 8 and awl carrier 26 is decreased, whereas, if the blocks 48 and 50 are adjusted downwardly, the range of movement of the swinging head and the awl carrier is increased. It follows, therefore, assuming that inone position of the parts, the driver and the awl are so spaced that the opening made in the work by the awl will be presented exactly in the line of drive, that if the blocks 48 and 50 were adjusted upwardly in the slot 46 and guideway 52 so as to decrease the ex tent of swinging movement; of the head. and the awl carrier without changing the spacing of the awl'and the driver, the awl 12, b reason of being then spaced from the driver by a distancegreater than the ex:- tent of swinging movement of the awl carrier, would not be moved far enouuh to carry the opening made in the work by it to the line of drive of'the fastenings. Conversely, 'if the blocks 48 and 50 were adjusted downwardly in the slot 46 and guideway 52 respectively, and the relative spacing of the driver and the awl'remained unchanged, the awl would, upon subsequent movement of the swinging head 8 to the left, carry the opening made by it in the work beyond the line of drive, so that in neither case would the opening made by the awl be properly alined with the driver after adjustment of the length of feeding movement of the work. In order to cause the opening made in the work by the awl to be accurately located in the line of drive of the fastenings regardless of variations in the range of feeding movement of the work, the slot 68 in'the awl bar carrier 26 is slightly inclined downwardly toward the driver, the degree of inclination being such that when the blocks 48, 66, and 50 are moved downwardly in the slots 4C6 and 68 and the guideway 52 respectively to increase the range of feeding movement of the work, the awl 12 will be moved away from the driver through a distance equal to the increment in the range of work feeding movement and, conversely, when the blocks 4:8, 66 and 50 are moved upwardly in the slots 46 and 68 and the guideway- 52 so as to decrease the range of feeding movement of the work, the awl 12 will be moved toward the driver through a distance equal to that by which the range of feed of the work is decreased.

In order that the adjustable blocks may be readily shifted in their guideways, a member 70 is attached to the block 50 and is provided with a handle for the ready manipulation of the parts to which it is attached. To adjust the slidable blocks it is necessary only to loosen the securing member 64:, by means of a screw driver, move the blocks by hand through the handle 70 and again adjust the securing member 64: to secure the blocks fixedly in position with relation to the arm 54. It will be noted that the means for adjusting the awl with respect to the driver and the means for adjusting the feeding stroke of the awl are bodily movable in a right line toward and from the awl. Conveniently a scale or indicator is provided as a guide for the operative in making the desired adjustments.

In repair work especially, it is frequently desired to change the extent of feeding movement of the work between successive fastening insertions, and it is, therefore, particularly to be desired in a machine de signed to be used for repair work that it be capable of-being adapted readily and quickly to insert fastenings at various spacings. Heretofore, however, it has been necessary in all of the machines in practical use with which applicant, is acquainted, to adjust the awl in the awl bar in a direction toward or from the driver and then by a separate adjustment provide for acorresponding change in the extent of oscillation of the swinging head and therefore in the feeding stroke of the awl. Much time and labor were often consumed in making these adjustments as the greatest degree of accuracy is required. Otherwise the fastening will not be driven into the perforations made by the awl. It will be understood that, in order to drive the nail properly, it is necessary that the driver bar, before its descent, be brought to a position directly over the perforations last made in the stock by the awl. In other words, the horizontal distance between the awl and the driver must be exactly equal to the length of the feeding stroke of the swinging head. If, therefore, the length of the feeding stroke of the awl be varied, as heretotfore explained, it' becomes necessary to adjust the relative positions of the awl anddriver ac'orresponding amount. By the mechanism herein shown and described, a single adjustment obtained by manipulation of the handle member 70 will secure simultaneously adjustment of the awl in its position with respect to the driver and a corresponding adjustment in the feeding movement of the awl. The advantage of theconstruction thus describedlies in the fact that the adjustment may be made with the greatest ease and the required degree of accuracy. A further advantage of the construction herein disclosed is found in the fact that the awl 12 may be secured in the awl carrier, by means of a plate 32, in such a way as to maintain the same always in true vertical alinement with the awl bar. Moreover, through the use of a plate like that shown at 32 accurate positioning of the awl with respect to the driver may be secured in setting up the machine and at other times should wear of the parts make such adjustment necessary.

The work rest 72 is provided with a slot 74 in which the fastening driving member and the awl move both in their reciprocations toward and from the work and also during their oscillatory movements as parts of the swinging head.
