FASTENING-INSERTING MACHINE.
Application filed December 11, 1922. Serial No.. 606,230.
To all whom, t may concern.'
Be it known that l, Grenen GonDU, a citizen o' the United States, and resident of VJinchester, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in F astening-Inserting Machines, of which the following description, in connection vvith 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 use in the manufacture of shoes and is illustrated herein as embodied in a machine having Work supporting means arranged to support and position the work during operation thereon by the machine, and to facilitate the presentation of the Work to the machine and its Withdrawal therefrom.
The illustrated machine isprovided with fastening inserting instrumentalities arranged to be introduced into the heel portions of shoes to insert fastenings therein, as, for example, to tack shank pieces into turn shoes. To facilitate the presentation of the work to the machine, in accordance with a feature of the invention, the illustrated Work support, While the machine is at rest, remains in Withdrawn position to permit the ready positioning of the Work With respect to the fastening inserting instrumentalities. and when the machine is started is moved into operative, vvorlesupporting lposition beneath the work, the arrangement being such that the Work support reaches operative position before the moving parts of the fastening inserting instrun'ientalities come into engagement With the Work. As illustrated, a back gage co-operates with the Work support to insure the correct positioning of tho Work with respect to a plurality of nozzles so that the fastenings will be driven at the desired location Within the shoe. It will be observed that a machine so constructed permits the operative to have free a cess to the nozzles in positioning the Work prior to the insertion of fastenings Without obstruction by the Work support, but brings the Work support into operative position beneath the Work prior to the insertion of the fz'lstenings and prior to the exertion of any force by the machine tending to more the Work out of operative position. i
llilhile the invention is illustrated as em-` bodied in a machine particularly designed for tacliing shank pieces into turn shoes, it should be understood that it is not limited to machines for this purpose but in various of its aspects is applicable to machines for performing other functions than the insertion of fastenings. Y
l'Vit-h the above and other features in View the invention will now be described in connection with the accompanying drawings and pointed out in the claims. Fig, 1 is a side elevation of a fastening inserting machine embodying the present invention' Fig. 2 is a plan view of a crank mechanism used in the machine of Fig. 1; Y
Fig. 3 is a front elevation of the head of the machine of Fig.
Fig. is a. cross section on the line lef-4f. of Fig. 3; and
F 5 is a side elevation, parts being broken away to show the construction of the upper end of the driver bar, driver bar guide and certain parts associated therewith. The illustrated machine is provided With a column and a head 12, the latter having pivoted thereto as at 14g a pair of brackets 16, each carrying a set of fastening inserting instrinnentalities18. In order to adjust tlie two sets of fastening inserting instrumentalities toward and from each other, as may be necessary for the proper insertion of fasteninfrs in shoes of diiferent sizes or styles, a right and left handed screw engages correspondingly threaded openings in the two brackets 16 so that b v its rotation in one di ret-tion or the other it may ausc their nu.` t'lon together or apart. A lock nut 22 is provided to clamp the tivo brackets 1o' 1n adiusted position. l
Slidablv mounted in each of the brackets 1G is a driver bar guide 30 in the form of a sleevehousinga driver bar 32 (Figs. 1 and 5). Each driver bar guide is provided with a rack 3l! meshing with a gear segment 36 pivoted at 38 to bracket 16 and arrangedfor oscillation. as will be more fully hereinafter described, by a link 40. At its upper end the driver bar 32 is pro-vided with a forwardly extending lug 4t2 Fig. 5) and a guide roll 44; co-operating with an appropriate surface A formed upon bracket 16 to support the iupper end of the driver bar during its reciprocating motion. Driver bar guide carries at its upper end an adjustably mounted cam 46 and a sleeve 48 to which is secured one end of a stift' coiled spring 50, the other end of which is operatively connected to the upper end of the driver bar as shown at 52. F ulcruined at 54 to eachbracket 16 is a. lever 56 formed at the rear and between its ends with a cam surface 58 and carrying at its upper end a roll 60 arranged to co-operate with the lower surface of vblock 42. At its upper end lever 56 is provided with a lug 62, the rearward movement of which is limited by a stop 64.l A spring pressed plunger 66 tends to rock the lever 56 rearwardly about its fulcrum 54. I
During the operation of the machine and after the insertion of each fastening, gear segment 86 is rocked to lift driver bar guide and with it driver bar 32.' At the conclusion of the upward movement of these parts lug 42 snaps past roll 60, which then serves as a stop to lock the driver bar in raised position, the parts at Vthisy time occupying the position shown in Fig. 5. `When gear segment 86 Amoves in the opposite direction (clockwise as vie-wed in Fig. 1), the driver bar guide 80 moves downwardly until the nozzle 68 carried at its lower end contacts witl the work, this downward movement of the driver bar guide tensioning spring 50. When cam 46, carried by the driver bar guide 80, during the downward movement engages cam 58 carried by lever 56, it forces that Llever forward so that roll 60 passes from under lug The driver bar 82 then descends, being driven in its downward stroke by the force stored in spring 50. y
A work support is arranged to vbe positioned beneath the work during the insertion of fastenings. A back gage 102 carried by a suitable slide on the head 12 of the machineand arranged to beclamped in adjusted position by a hand screw 108 is located to the rear of nozzles 68 so as to facilitate the positioning of the work with respect thereto.
' In order that the operative may have unobstructed access to the back gage and oper-` ating instrumentalities of the machine, the
In order to ensure that the work support shall be in position before the nozzles 68 come into `engagement'with the wom, gear segments 108 and 112 are of such dimensions that the work support reaches its operative position before the nozzles 68 have com'pleted'their downward movement. vWhen t-he work support has reached this position further Aforward movement thereof is prevented by engagement of a stop carried by slide 104 with a co-operating stop member 141 carried by a stationary part of the machine. Vihen the work support reaches its operative position and can move forward no further the spring plunger 116 is compressed to permit relative movement of gear segments 108 and 112 so that rack bar 118 can continue its forward movement until the nozzles come into engagement wit-h the work on the work support, immediat-ely after which the driver bars are tripped to drive the fastenings into the work.
To permit the work support to adapt itself to the contour of different' sizes and styles of slices, it is provided with a work engaging member 146 (Fig. 3) having an arcuate lower surface provided with a lug 148 positioned between co-operating spring pressed plungers 150 housed in a carrier 152, the latter being provided with a slot conforming to member 146 so that the latter may rock laterally in the carrier while providing a firml support for the work. Carrier 152 is provided with a downwardly extending stem 154 counterbored to form a housing for a spring 156, an abutment carried by slide 104 being provided for the spring at 160. At its forward end slide 104 is provided with vertical guides 162 co-operating` with corresponding ways formed upon stem 154 to guide the carrier 152 in its vertical movement. From the foregoing it will he apparent that the work support is4 arranged to conform itself both to the thickf ness of the work and to its contour so that the work will be firmly but not too rigidly supported during the insertion of the fastenings and will yield to prevent injury to the work hy nozzle 68.
rl`he machine is provided with a treadle 180 suitably pivoted at the rear to column 10 and connected by a link 182 to a two armed lever 1.84, 186 suitably fulcrumeo. upon the head of the machine. Arm 186 of this lever is arranged when depressed to strike the forwardly extending arm 188 of a three armed lever fulcrumed at 190 to the head of the machine and provided with a rearwardly extending arm 192 and an ,upwardly extending arm 194. Anchored to the arm 194 is a spring 196 tending to rock the three armed lever is a counter-clockwise direction, as viewed in Fig. 1. Arm 192 of the three armed lever is pivoted to an upwardly extending lever 198 which is urged rearwardly as viewed in Fig. 1 by a spring 200 connected at one end to lever 198 and at the other end to an arm 202 of a second three armed lever provided also with a forwardly extending arm 204 and an upwardly and rearwardly extending arm 206. A block 208 carried by link 198 contacts with a block 210 carried by the forwardly eX- tending lever arm 204 so that upward movement of lever 198 rocks three armed lever 202, 204, 206,'in a counter-clockwise direction, as viewed in Fig. 1.
The machine is provided with a main drive shaft 212 receiving power from any suitable source and carrying a worm .214 meshing` with a worm wheel 216 loose on shaft 80. Fast upon a shaft 80 is a disk 220 provided with a lug 222 in the path of movement of which is located the upper end of lever 198. Vorm wheel 216 and disk 220 contain the. co-operating parts of a hole 224 in which is mounted a pin 226 having its end portion cut away, as indicated at 228 in such a manner that when positioned as shown in Fig. 1, the worm wheel 216 and disk 218 are disconnected but when rotated through approximately 90 degrees, the worm wheel and the disk are clutched together to transmit power to the machine. Pin 226 is provided with a controlling finger 230 which, `when the machine is at rest, engages a block 282 carried by lever arm 206. A safety stop 233 may conveniently be provided tocooperate with a 1inge1234 carried hy pin 226 to lock the pin in the position shown inFig. 1 so that no power can be transmitted. During the operation of the machine this stop 233 is, of course, withdrawn from the path of linger 234. A, spring 236 tendsto rotate pin 226 in a counter-clockwise direction, as viewed in Fig. 1, so that when lever arm 206 is rocked in a counter-clockwiseV direction hy the upward movement of lever 198, block 282 is withdrawn vfrom engagement with controlling finger 280 and pin 226 is rotated by spring 236 suliiciently to connect worm wheel 216v and disk 220 with the consequent operation of the machine through a single cycle. Towards the conclusion of the cycle, lug 222 engages the upper portion of lever 198 rocking that lever forwardly against-thetension of spring 200, thus moving block 232 into position to engage controlling finger 230 so that at the conclusion of the cycle pin 226 is rotated against the tension of spring 286 to disconnect worm wheel 216 and disk 220, the machine coming to rest in the position indicated in Fig. 1. clutch mechanism is provided by means of which the machine will be caused to operate through a single cycle and then come to rest. y
lVhile the operation of the machine has been described in connection with the description of the machine, it may be convenient briefly to recapitulate'. In utilizing the machine to tack a shank piece into a turn shoe, the shoe with the shank piece therein is presented with its counter portion'surrounding nozzles 68. To hold the upper of the shoe away from the nozzles a shield 250 may `conveniently be provided. l/Vith the shoe thus located and 4with the rear part of the counter portion of the shoe positioned Thus, it will be seen that y iso against back gage 102, the operative trips the treadle, whereupon slide 11S moves forward rocking gear segments 112 and 108 so as to move the work support forward beneath the work and simultaneously lowering the nozzles into engagement with the work. The work support reaches its operative position and comes to rest beneath the heel seat portion of the sole of the shoe to be operated on before the nozzles engage the shoe, the spring of plunger 116 being compressed during the latter portion ofthe downward' movement of the nozzles. lf'tlhen the nozzles reach the work or immediately thereafter, cams 46, carried by the driver bar guides whicn also carry the nozzles at their lower ends, contact with kcams 58 rocking levers 5G in a clockwise direction, L s viewed in Fig. 5, thus releasing driver bars l2 which descend and insert the fastenings. mmediately after the descent of the driver bars, slide lS starts rearwardly, withdrawing the work support and elevating the driver bar guides, the latter carrying with them the nozzles and the driver bars. f
