SPECIFICATION forming part of Reissued Letters Patent No. 9,315, dated July 20, 1880.

Original No. 17!,609, dated December 26, 1875.

To all whom it may concern:

Be it known that 1, 1101718 GODDU, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and usel'ul Improvements in Screw Cutting and Inserting Machines for Fastening the Soles to the Uppers of Boots and Shoesrand I do hereby declare thatthe t'ollowin g is a full, clear, and exact description ot' the invention, which to will enable others skilledin the art to which it pertains to make and usethe same, reference being hadto the accompanying drawings, and to, the letters of reference marked thereon,

. which form a part of this specification.

1 ln machines of this kind hitherto constructed the screws have been cut in a continuous manner upon the wire-and while being so out are screwed or entered into the work to unite the parts. In such method however, the

screws cannot have solid heads.

It is one of the essential features of my invention to so form the screws that the-thread oi'cach shall terminate in a solid head by the severance of each screw from the wire at a 2 5 point'just above the termination of the thread after the screw'has been enteredinto the partsto be united by it. The thread, however. is formed and completed previous to the operation of entering the screw into the stock.

0 This plan overcomes objections hitherto existing, such as heating the wire under the simultaneous operations of cutting the thread and inserting the screw.

In the organization of this machine the cutmake the severance of the inserted screw close to that part of the solo upon which the cutters rest, thus saving wastc over the modes hitherto practiced.

With a machine l'or forming and inserting solidliea-dcdiiscrews made from a continuous length ot' wire carried by an intermittently vertically moving spindle I have combined a cutter to operate within and at the upper 4 5 surface of the born or other work-support, the

purpose of which is to cut off the surplus length of the screw which projects through the inner sole into an opening in the horn,

thus leaving the surface of the inner sole per- 5o fectly free from projecting screws.

Application for icissue filed May 11, 1880.

v l V The action of the cutter located in the horn is simultaneous with that of the knives which sever the screws from the wire,and the action of both must necessarily precede the feed of the work upon the horn.

The cutters for severing the wire above the work are so located with relation to the work and the direction of the feed as to reciprocate or vibrate in a. plane parallel with the direction of the movement of the feed and of the shoe acted upon by the feed, and thecutters are so supported and attached to their actuating or carrying levers as to extend, as shown, below the arms or levers to which the said cutters are attached.

The alternate grasping and releasing-of the wire within the spindle, to give it a revolving motion to cut the thread and screw it into the work, is a serious objection, which my machine entirely remedies, for the wire is herein 70. held and made to turn with the spindle during the entire operation of the machine, but without at all times cutting into its surface. The devices by which to accomplish these results are very simple in construction and operation.

In connectioii with the devices to give to the wire its rotary motion and allow it to move'in the direction of its length, I cmploya feeding construction to feed the wire for the successive formation of screws, while the device that engages the wire to turn it remains in full force-that is to say,'docs not relax its hold on the wire. This feedin device consists, primarily, of a verticallymovable section of the vii"--carrying spindle, and fulfills its function by the employment of ie stop havdetermining cut different 0 ing the capacity of varying and the feed of the wire to form and lengths of'screws. v v

' In connection with the vertically-movable horn I employ a compound weighted treadlc, upon which the horn rests, the treadl'e being provided with a knee-joint, a springeconnec- 5 tion, and an operating-cam],whereby l obtain a cushioned or yieldingsupportfor the born, the knee-joint being'tlexcd' when 'it'is desired to lower the born to place or remove the work.

The wire is fed to the spindle from a spool ioo IO ing raised; Fi

(See Fig. 4.) This construction permits the spindle to be raised and lowered as it is being rotated continuously, the ribs being long enough to allow the necessary vertical movement of the said spindle to feed down the wire for and insert the screw.

The wire-feeding device is composed, essentially, of a pair of rollers, J J, circumferentially grooved or corrugated, or scored, as in Fig. 5, 'to engage the. wire without slipping thereon. The rolls have their bearings in a holder, H, and plate H, adjustably attached to the said holder by a screw, to thus enable the rolls to be adapted to the wire being used-and take out bends. The holder H is attached to the spindle ,l) at its upper end, 1

the horn in this way prevents marringthework as thefeed lstrikes it, and obviates the dis-, placement of the inner sole. This increased resistance of the horn is made effective only during'the'downward thrust of the screw or fastening, and as it is in contact with and is being inserted in the stock or sole. The screw X, (see Fig. 13)th2 tt supports the lower end of the spring P may be adjusted to increase. or

details described, but to vary the same so long as the essential combinations and results described are obtained.

As suming the spindle to be at its highest point asshown iirl ig. 3, with wire enough to form-one screw projecting below it, and power applied to operate the machine, the screw-chaser X and the wire-support N are brought in position to act, upon the wire and it as the wire clamped, as

described by the rollers d, is rapidly rotated continuously in one direction by the spindle, it'in the meanwhile being made to descend at a speed proportional to the number of screwthem until the screw or wire is carried L are caused to act, severing the screw from threads desired to the inch until a length suflicient for one screw has been formed, after which the arms N carrying the chasing device and support N, open quickly to give'room for the spindle to move down rapidly between fastening reaches the work, when the resistanceof the horn in opposition to the thrust of the fastening is increased, as before described, speed at which same as when cuttingthe thread on the wire,

The rotary anddescending motions of the spindle continue until the :full length of the screw is inserted and'a little of the unthreaded into the sole, when the cutters the main length of .wire flush with that part of the sole or leather on which the cutters rest, making a screw with a solid head, m, (See Fig. 1b.) During this operation the spool E, from which the wire is being fed, revolves with the spindle. I

In order that each screw may have perfect hold in the inner 'sole,its end is made to'extend through the said the nose of the horn, where the screw is clipped off by the cutter i close to the face of the inner sole, leaving the shoe perfectly smooth inside.

The screw or fastening having been out 011', the increased resistance of the horn is relaxed, and as the spindle I) rises the foot lfeeds the shoe in the direction of movement of the cutters L. Before the spindle D reaches its highest point of ascent the rod I, moved upward to its normal position by the spiral spring I", strikes the feed-governing stop K, which has previously been set in the required position, according to the length of screw or fastening next to be made, and arrests the upward movement of the rod- I, while the spindle D 'c0n tinues its ascent. The rod I having reached the stop K, farther ascent of the spindle causes the teeth I of the rod, in engagement with the toothed sector I, to move it,

to turn the ratchet a on it. Then the treadle is released am?- vantage results from v in, as is' well understood,

This fea-- ture distinguishes this mach-inefrom all others. Another highly important advantage consists'in imparting to the spindle an intermittent vertical movement, whereby the wire is first threaded in plain sight of the operator and then inserted. This avoids the heating of the wire. By subjecting it to only one operation at a time the operator is enabled to see if the chasing-tool is doing its work properly, and tostop the machine before an imperfect screw is inserted. In these respects, also, this machine is of wholly novel construction.

Although I have described the machine as adapted to the manufacture of boots and shoes, yet it is obvious that it can be used to advantage in uniting the seams of hose, belting, and other similar work, and the work may be supported upon an adjustable jack, such as is used 'in wood-pegging machines, as my invention is not limited to that class of machines employ ing a rotating work-supporting horn, yet I prefer and consider it of great advantage to use sucha born. When the horn is not employed the interior cutter and its operating devices need not be used, as I shall thenrely on the position of the stop K to insure the production and insertion of a screw ot" the proper length.

This' machine is also equally well adapted for inserting screws without solid heads. In such' case,

however,- thef-wircrscvering cutters must be made to work quicker to sever the produce the q 6o forth.
