FASTENING-INSERTING MACHINE.

To all whom it may concern:

Be it known that we, ARTHUR ERNEST JEnnAM and JosErH GonLDBoURN, subjects of the King of England, residing at Leicester, Leicestershi e, England, have invented certain Improvements in Fastening-Inserting Machines, of which the following description, in connection with the accompanying d 'awings, is a specificationflike reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for inserting fastenings. By Way of illustration the invention is herein'shown as embodied in a machine of the type disclosed in United States Letters Patent No.5t90,621, granted. January 9A, 1893, on an application of Louis Goddu, for inserting screw threaded fastenings in the soles of boots and shoes.

In the use of machines of the general type disclosed in said Letters Patent on some classes of work, the maximum spacing desired exceeds considerably the maximum spacing obtainable with machines of this type as these machines have been constructed heretofore, Also, it is frequently desired to make considerable changes in the spacing of the fastenings at different parts of a given shoe. Consequently, in such cases, it has been necessary for the operator to ad Vance the work manually between successive fastening locations, depending necessarily upon his own skill and accuracy to effect the different spacings properly and to locate the fastenings correctly, with the result not'onlytha t especial skill has been re quired on the part of the operator and the operators work has been rendered considerably more laborious, but the output of the machine has been reduced considerably and the results obtained have generally been unsatisfactory.

One of the objects of the present invention is to eliminate these disadvantages by producing an improved fastening inserting machine especially adapted for inserting screw threaded fastenings in the soles of boots and shoes, which machine may readily be rendered capable of dealing either with any ordinary and normal spacings or with spacings considerably outside of the normal range of spacings.

A further and more particular object of the invention is to provide an improved fas Specification of Letters Patent. Application filed July 26, 1916. Serial No. 111,527.

ratemea is. so, rare.

tening inserting machine of this general type so constructed as to permit a change from normal to extra wide spacing to: be made at the will of the operator without interrupting the operation of the machine to provide for effecting any desired changes of spacing during the operation upon a given shoe without necessitating either stopping the machine or rendering necessary a second series of operations upon that shoe to insert the extra widely spaced fastenings after the normally spaced fastenings have been inserted.

In accordance with these and other objects of the invention, the illustrated machine is provided with novel manually controlled means capable of initiation by the operator at any stage in the operations ofthe machine, which means are so constructed and arranged that whenever extra Wide spacings are desired the operation of the fastening inserting mechanism may be suspended periodically Withoutsuspending or interfering with the operation of the work feeding mechanism, to the end that the amount ofv work feeding movement between successive fastening insertlng operations may be doubled, thereby doubling the spacing range of I the machine.

Preferably, and as shown, the illustrated means for periodically suspending the op eration of the fastening inserting mechanism is organized to not automatically at regular intervals during the operation of the machine, the construction and arrangement being such that the initial suspension of operation of the fastening inserting mechanism will invariably occur at a predetermined point in the cycle of operations of the machine regardless of when the operator actuates the means for suspending the operation of this mechanism. As herein shown, this result is accomplished by automatically suspending the operation-of the fastening inserting mechanism at a predetermined time between each two fastening inserting operations, so that, as long as extra wide spacing is desired, the work feeding mechanism will impart to the work two work feeding steps between every two successive fastening inserting operations.

These and other objects and features of the present invention will be apparentfrom the following detailed description of a maautomatic chine of the above mentioned type having a preferred embodiment of the present in vention incorporated therein, and the novel features of the invention are defined in the appended claims.

Referring to the drawings,

Figure 1 is a side elevation of the upper portion of the machine; and

Fig. 2 is front elevation partly in section, showing certain parts of the upper portion of the machine of Fig. 1 on a somewhat larger scale.

The machine in which the present invention is herein shown as incorporated is substantially the same as that disclosed in said above mentioned Letters Patent except as hereinafter set forth, and reference ma be had to said Letters Patent for a more de tailed description of the construction and operation of certain parts not fully described herein.

The machine has a base carrying a column 2 which supports a head 4 having mounted. therein a vertically disposed spindle 6 which carries the screw threaded wire from which the fastenings are formed. The spindle 6 is continuously rotated by a belt passing over a pulley 8 on the upper end of the spindle and over idlers 10 to a driving pulley (not shown) in the base of the machine arranged to be clutched to a continuously running pulley operated from a source of power. The spindle 6 is provided with a worm which engages worm gears 20 (Fig. 1.) upon the forward ends of parallel shafts, one of which is indicated at 22, this shaft 22 carrying the various cams for effecting the wire feeding, wire severing, work feeding, and horn depressing movements. These cams are each formed to cause two operations of the parts operated thereby during eachcomplete revolution of the cam shaft 22.

The wire is fed downwardly through the spindle 6 by a wire feeding and inserting sleeve 2 1 surrounding the spindle 6 and slidably mounted in guideways in the ma chine frame, the lower end of said sleeve being provided with wire gripping members 26 which operate intermittently to seize the wire as said sleeve is moved downwardly. The sleeve 24 is reciprocated in the machine frame to feed successive lengths of wire and insert them in the work by a wire feed lever 28 (Fig. 2) pivoted at 30 to the machine frame and having two forwardly pro jecting arms 31 (Figs. 1 and 2) each carrying a segmental gear 32, the gears 32 engaging respectively racks 34 formed on a yoke attached to the upper end of the sleeve 24. An upwardly extending arm 36 (Fig. 2) of the lever 28 carries a cam roll 38 operatively engaged by a wire feeding edge cam $0 on the cam shaft 22. A wire feed lever 28 is normally held in position to be operated by the cam 10 to move the wire feeding sleeve 2% downwardly by a comparatively strong spring (not shown) the lower part of which bears against a part of the lever 28.

After a proper length of wire has been inserted in the work, the wire is severed by wire severing knives mounted in the lower ends of two knife carrying arms 41-1 and e13 both fulcrumed on a shaft 4:7 mounted in the machine frame. The knife carrying arms or holders 11 and d3 carry gears (not shown) which mesh with coeperating gears on the forward end of a shaft 51 (Fig. 1). Upon rocking movement of the shaft 51, the holders 41 and 13 are reciprocated toward and from each other to cause the cutting edges of the knives to sever successive lengths of wire intimed relation to the operation of the wire feeding mechanism. The shaft 51 is oscillated through connections to a wire severing cam 4.5 provided with two outstanding toes one of which is shown at 53 and a daptcd to operate intermittently a lever 49 operatively connected to the shaft 51.

In the use of the machine the shoe to be operated upon is mounted upon a horn (not shown) and clamped between the horn and an abutment indicated at In order that each wire fastening inserted in the work may correspond to the thickness of the work at the fastening location, the extent of feeding movement imparted to the wire feed lever 28 by the wire feeding cam 40 is automatically varied. This is effected by providing the horn with a laterally extending arm (not shown) to the outer end of which is attached a measuring rod or leg 59 (Fig. 2) projecting upwardly through a guide in the machine frame and adapted upon upward movement of said rod to engage and more upwardly a cooperating rod 61, the lower end of which is in line with, but normally spaced from, the upper end of the rod The rod 61 has its upper end pivotally secured to the end of a rearwardly extending arm 63 of the wire feed lever 28. lVhenevcr the horn is moved upwardly into work clamping position. the measuring rod 55) is correspondingly moved to engage and move the cooperating rod 61, whereupon the wire feed lever 28 is adjusted in respect to its operating cam 40 according to the thickness of the work.

After each fastening has been inserted and cut off, the work is automatically fed by a feed wheel 12r- (Fig. 1). The feed wheel 127 carries on its under side a. bevel gear indicated at 123 meshing with a bevel gear 125 on the outer end of a shaft 129. The opposite end of the shaft 129 carries loosely a toothed sleeve 131 adapted to be oscillated by a rack 139 (Fig. 2) on the lower end of one arm of a two-armed lever 133. The other arm 141 of this lever has a stud and slot adjustable connection inditends to force the rod 50 downwardly and operates to restore the lever 52 to normal position after movement thereof against the pressure of the'spring 66.

In the illustrated machine, as in the machine of said Letters Patent No. $0,621, the operating cam d0 for the wire feed mechanism, like the Wire cutting mechanism cam 4:5, is a double throw cam so constructed that during every revolution of the cam shaft 22 two operative movements 7 of the wire feeding mechanism areeffected. The present invention provides means for automatically and periodically swinging the lever 52 once in every revolution of the cam shaft 22 whenever said meansis operative, thus throwing over the latch 56 and setting the switch 58 to suspend the operation of the wire feeding mechanism once in every revolution of the cam shaft so that, when extra wide spacing is desired, every alternate Wire feeding movement will be omitted automatically and, instead of feeding and inserting two fastenings during each revolution of the cam shaft, the machine will insert one fastening onlyduring each revolution of the cam shaft.

Inasmuch as the described means for periodically suspending the operation of the wire feeding mechanism is independent of, and doesnot interfere With, the operation of the work feeding mechanism, it will be seen that, whenever the said means is operative, the work will have imparted to it tWo feeding steps or movements between each two fastening inserting operations, thereby exactly doubling the spacingcapacity of the machine. As shown, the means for thus automatically and periodically swinging the lever 52 independently of the trea'dle rod 50 to effect alternate-suspension of the operation of the wire feeding mechanism comprises a double armed leverpivoted on the machine frame on an extension ofthe shaft which carries the wire feed arm 31, which double armed lever carries on one arm 68 a roll 70 adapted to be engaged by an edge cam piece 72 fitted on the wire feed operating cam 40 and operating to swing the double armed lever once in every revolution of the cam shaft. The other arm 74 of the double armed lever is pivotally connected to one end of a rod or plunger 76, the other end of which rod is arranged to be received in a recess 78 (Fig. .2) at one side of the lever 52. A spring 80 Fig. 1) connected at one end to the machine frame and at the other end to the rod 76 acts both to force the rod 76 laterally in line with the recess 78 and also in the direction to maintain the roll 7 0 in contact with the edge piece 72 on the cam 40. Located in supports in the machine frame at one side of the rod 76 is a rotatable shaft indicated at 82 (Fig. 1) carrying a cam 84 so located that rotating of the shaft 82 displaces the rod 7 6 laterally against its spring 80 out of line with the recess 78 so that, in the reciprocation of the rod 76 by en g ment of the edge cam piece 72 with the roll 70 on the double armed lever, the rod 70 does not enter the recess 78.

The rotatable shaft 82 is designed to be provided with connections to a knee lever or treadle (not shown) by movement of which the operator may rotate the said shaft at will during the operation of the machine to cause the lever 52 to be operated to move the latch 56 and set the switch 58 periodically once in every revolution of the cam shaft 22 to suspend the operation of the wire feeding mechanism.

In the use of the illustrated machine, the operator, in commencing operations upon a given piece of work, depresses the treadle which operates the treadle rod 50, thereby through the lever 52 and spring blade 5 L positioning the latch 56 to set the switch 58 to render the wire feeding and cutting mechanisms and the horn raising and (lepressing mechanisms operative. If normal spacing is desired, the knee lover or treadle controlling the periodic suspension of the Wire feeding mechanism is set to position the shaft 82 so as to displace the rod 76 laterally out of line with the recess 78 in the lever 52. Whenever extra wide spacing of the fastenings is desired, the operator moves the said knee lever or treadle oppositely to rotate the shaft 82 so that the rod 76 will be positioned by its spring 80 in line with the recess 78 in the lever 52 whereupon, once in every revolution of the cam shaft 22, the lever 52 will be moved to set the latch 56 to operate the switch 58 in the direction to force the wedge shaped block 60 into operative relation to the rod (31, thereby forcing the cam roll 38 on the upward extension 36 of the wire feed lever 28 out of the path of movement of the cam 40 and, at the same time, through the connections above described, rendering the wire cutting mechanism inoperative. So long as the rock shaft 82 and the rod 76 are so positioned, the Wire feeding mechanism will operate once only in every revolution of the cam shaft 22, and consequently only one wire feeding movement will be effected for every two work feeding movements.

It will be noted that the operation of the illustrated embodiment of the invention is entirely positive, with the result that maintenance of accurate time relationship of the parts of the control mechanism relatively to the other operating mechanisms of the machine is assured.

Although the invention is herein shown and described as embodied in a machine of the type set forth in said Letters Patent No.

490,621, it is to be understood that the in- May 23, 1916, for fasteninginserting machines.
