SPECIFICATION forming part of Letters Patent No. 403,835, dated May 21, 1889.

Application filed July 30,1888. Serial No. 281,387. (No model.)

T at whom it may concern: One feature of my present invention con- Be it known that I, LOUIS GODDU, of Winsists in the combination, witha wire-carrying chester, county of Essex, State of Massachuspindle and feed-rolls therein and a reciprosetts, have invented an Improvement in Macatin g sleeve having spiral or diagonal flutes, 5 chines for Uniting Soles to Uppers, of which of a spirally or diagonally fluted clutch-sleeve the following description, in connect-ion with and means actuated thereby to move the said the accompanying drawings, is a specification, feed-rolls.

I like letters on the drawings representing like In machines heretofore known to me using parts. v a screw-threaded wire passing from a spool 10 This invention is an improvement upon through a vertical spindle driven by a belt that class of machines wherein a threaded the entire bearing for the spindle has been wire is fed through the spindle into the stock located below the spool; but herein the wiresupported upon a horn, the feed of the wire carrying spindle has bearings close to and being variable to automatically adapt the maboth above and below the spool, the spindle I 5 chine to the thickness of the stock upon the so supported running very accurately and horn, the end of the wire being screwed into smoothly. the stock substantially to the horn and then In the machine herein to be described the cut oif, leaving the fastener of a suitable driving-pulley ,for the spindle is extended length for the stock. The wire which I predown around the upper bearing for the spin- 2o fer to use has two threads, substantially as die, so that the strain of the driving-belt describedin United States Patent No. 370,136, upon the pulley is borne by a portion of the granted to me on the 20th day of September spindle within a bearing, or, in other words, 1887, to which reference may be had, and it the spindle is supported in the line of the will be noticed that the threads of the wire at strain of the belt upon it.

The operating-edges of the cutters herein shown are directly opposite each other, so as to cut through the wire described in a diametrically straight line, each cutter having a like bearing upon the wire at its opposite sides, thus preventing any tendency to bend or twist the wire out of shape. It is a great desideratum that the wire between the throat and the stock be straight and free from bends.

The machine herein to be described has also been provided with peculiar means under the control of a lever for suspending the feed of the wire. So, also, the machine contains a novel feed mechanism for feeding the stock over the horn.

Particular features of this invention will be hereinafter described, and specified in the claims at the end of the specification.

25 shows portions of the feed-rolls on an enlarged scale side by side to illustrate the positions of its projections and spaces. Fig. 26

is a section showing the wire between the feedrolls, and Fig. 27 shows a piece of the doublethreaded wire enlarged.

The frame-work, of suitable shape to support the various parts, is composed, essentially, of a column, A, base A, and head A The column A supports a stud, A on which is placed loosely a belt-pulley, A driven from a suitable shaft, and also a belt-pulley, A, the contiguous faces of the said two pulleys being of cone or other usual shape to constitute friction-pulleys, the hub of the pulley A being beveled to be acted" upon by a beveled slide, A, to force the pulley A against the constantly-moving pulley A whenever it is desired to run the machine, the said slide being under the control of a treadle, A The pulley A in practice, is surrounded by abelt, (not shown,) which is extended over two like guide-pulleys, A only one being shown, and then about the pulley A fast to the wirecarrying spindle A the connection being preferably by a righthand screw-thread, the pulley being retained in place by a check-nut, A united to the spindle by a left-hand screwthread.

The horn B, of usual shape, is free to be rotated on the horn-shaft B, made vertically movable in suitable bearings in the column A, the horn-shaft being prolonged by a rod, B screwed into its lower end and jointed to a treadle, B the said rod being surrounded by a spiral spring, B, resting on a washer, B supported by the column A, the upper end of the spring receiving against it an adj ustable nut, B, screwed uponthe rod B the spring thus supporting the horn in a yielding manner, the upward movement of the horn being limited by a nut, B screwed to the hornshaft.

The treadle B at its rear end, has jointed to it a rod, B the upper end of which is in turn jointed (see Fig. 19) in an adjustable manner to an arm, 13, of peculiar shape, and shown separately in Fig. 23, wherein itwill be seen, as also in Fig. 19, that the saidarm has a U-shaped projection, B having a roller or other stud, B which enters a cam-path, B in a cam, B fast on the cam-shaft B. The arm B has its fulcrum on a stud, B and the rotation of the cam B through the devices described raises and lowers the horn automatically twice during each rotation of the shaft, the horn being depressed just before the feed is to take place, two nails being inserted at each rotation of the cam-shaft. The stud B also serves as the fulcrum of a lever, 0, (shown partially in dotted lines, Fig. 19,) having an adjustable toe, 2,which is acted upon by the lugs 0 0 inserted in the periphery of the cam B outer end, (see Figs. 1 and 19,) is split to receive a pin or stud, G on which are placed and retained loosely two connecting-rods, 0 C

The lever O, at its the one 0 having, preferably, an adjustable cutter-carrier the said carrier having se cured to it by a bolt, 0 a clamp, 0 one of the cutters, a, being firmly clamped between the said carrier and clamp. One of the cutters to a is shown separately in Fig. 15. The said cutter is of arc shape, and may be readily adjusted in position between the carrier and clamp as worn away by grinding.

The rod 0 is joined by bolt D to an arm, D, clamped to the sleeve-like shank D of the cutter-carrier D having co-operating with it a clamp, D connected thereto by a screw, D the cutter a being clamped between the said carrier D and clamp D The sleeve-like shank D serves as a bearing for the shank C and in turn takes a bearing at D in a rigid part of the frame-work.

The lever C has a depending arm, (see Fig. 19,) which is acted upon by a spring, O flwhich spring normally keeps the said depending arm against the stop O, in. practice made adjustable on the head A the cutters a a being fully open for the passage of the wire when the saidarm is against the said stop, adjustment of the stop providing for a greater or less separation of the cutters.

Each carrier is cup -shaped, and each is moved at the same time for like distances, but in opposite directions, so that the said cutters are made to approach and cut into the wire from opposite sides to its center and then to separate for the passage of the end of the wire beyond the cutters. The cup-shaped carriers receive within them and they oscillate about the spherical end a? of the wire-carrying spindle A composed of several parts, the spherical head having an extension, a provided with a shoulder at a above which the extension is provided with a series of straight flutes, as at a the upperend of the said extension receiving upon it (see Fig. 3) anut, (1. the latter connecting the extension (0 with the main body of the spindle; the said main body having secured to or forming part of it the yoke a carrying the stud a, on which is mounted and turns the spool a which carries the wire. The upper end of the spindle A turns in a bearing, D and between the said bearing and the hub-of the pulley A is interposed an antifriction bearing, a, composed, essentially, of two plates and interposed conical rolls.

The spindle within the bearing D is bored to receive a presser-rod, a having a presserplate, a", to bear on the wire on the spool by a force measured by a spring, a surrounding the said rod, the latter at its upper end having a hand-lever, c0 by which to lift and hold it when desired. The spherical end a of the spindle carries a throat-piece,b, inline with the wire-passage b, and it has (see Fig. 4) a pin, b held in a spring-plate, b (shown detached in Fig. 6,) on which pin is mounted to turn one of the wire-feed rolls b havinga gear, 0 at one end, which meshes with alike gear, 0 on the feed-roller I)", held in place by the stud-screw If, both the said feed-rolls having annular scored grooves to fit the threads of the wire, as will be hereinafter described. The spring-plat-e b has a lip, 3, which (see Fig. 5) enters a notch in the spindle, and is held in place by a set-screw, b, the latter also regulating the pressure of the rolls on the wire.

The spindle A takes a second bearing in a rigid part, D of the frame-work, the said rigid part being provided (see Fig. 11) with guides D which are embraced by cars of a U-shaped yoke, D (see Figs. 3 and 11,) provided with an opening through which is extended loosely the feeding-sleeve 0, (see Figs. 3 and 7,) the upper end of the said sleeve having screw-threads, as 4, which screw into a flanged nut, 0', having, as shown, a beveled under face which bears upon a series of conical anti-friction rollers, 0 the said rollers resting upon a portion of the said yoke near the feeding-sleeve c. This yoke at its rear side is provided with rack-teeth, as best shown in Fig. 1, which teeth are engaged by sectorteeth, as 5, at the end of a double-armed lever, D, loosely mounted on a stud, D the said lever having a roller or otherstud, as D, which is acted upon twice during each rotation of the cam-shaft B by a cam, D", secured to the said shaft, the said cam through the said lever lifting the said yoke and with it the said sleeve.

To enable the extension a to be more firmly secured to the spindle A than it could be by the nut a alone, I have provided the said extension with the straight flutes a (see Fig. 5,) thus forming a series of projections which enter grooves of corresponding shape cut in a chamber at the lower end of the wire-spindle A the said projections and grooves be ing shown as engaged in Fig. 9, that figure being a section of Fig. 3 in the line 00 .A friction-washer, 0 is interposed between the shoulder a of the extension a and the end of the spindle A The spherical head aireceivc s'in it a stud-screw, 0 which serves to hold loosely a beveled pinion, 0 having a sleeve-like shank, 0, (shown separately in Fig. 5",) which is also toothed, the teeth of the sleeve portion 0 (see Fig. 3) engaging the teeth 0 of the feed-roller 5 before described. The stud-screw c has a hole, 25, (see Fig. 3,) in line with the wire-passage in the spindle, and the wire passes through the said hole t on its way to the feed-rolls.

To revolve the beveled pinion c, the machine has a crown-gear, d, (see Figs. 1 and 3,) forming part of a sleeve, cl, surrounding the extension a" loosely, the latter acting as a guide for the said crown-gear, the teeth of the crowngear which are not in engagement with the said beveled pinion nearly touching the race (1 (see Fig. 5,) the wear of the said teeth upon the said race being obviated by or through conical anti-friction rollers (1 interposed between the beveled shoulders d (see Fig. 5) and a reversely-beveled shoulder at the interior and at the lower end of the sleeve d, as best shown in Fig. 3. Fig. 10 shows ITO one of these series of anti-friction rollers, the section of Fig. 10 being in the line 03 Fig. 3, through the rollers referred to.

The upper portion of the crown-gear referred to has a series of ratchet-teeth, d, (see Figs. 1 and 18,) which are adapted to be engaged by a like series of ratchet-teeth at the flanged lower end of the sleeve 6, the latter sleeve surrounding the tubular shank d of. the crown-gear.

The feeding-sleeve c referred to has. a collar, 6, which bears against one washer on plate of an anti-friction box, E, containing a series of conical rollers and interposed be-j tween the said collar 6 and the lower end of the yoke D Below the collar 6 the, sleeve 0' is provided with a series of diagonal flutes, e, and :internally the said sleeve 0 is grooved; longitudinally to leave teeth and spaces to engage corresponding spaces and teeth out; longitudinally in the periphery of the spindle A 9, as shown by dotted lines in Fig. 3 and by. full lines, Fig. 1, from the lower end of the bearing D down tothe lower end of the said: spindle.

The upper end of the sleeve 6, surrounding the lower end of the sleeve 0, is fluted or; grooved internally to correspond with the external flutes or grooves, e, of the sleeve 0, so that the said flutes or grooves in engagement; when a reciprocating movement is given to the sleeve 0 will oscillate the sleeve 6 more or less about the sleeve 01 and extension a and causethe'flanged part of the said sleeve 6 to, by its ratchet-teeth, engage the ratchet-teeth of and move the crown-gear d a greater or less distance, that depending upon the length of the reciprocation of the sleeve 0. In this way intermitting movement in one direction is given to the crown-gear d to enable it, through the gears 0 to rotate the feed wheels drrollers b b to feed the wire and thrust it into the stock at the proper time for the proper distance. As the longitudinally-fluted external portion of the spindle A engages: corresponding flutes at the interior of the feedingsleeve 0, it follows that the said sleeve 0 rotates in unison with the. spindle A driven by the belt on the pulley A and the sleeve 6, which. forms a coacting part of the feed-sleeve 0, also rotates-in unison With the spindle A but it will be noticed that the crown-gear d does not rotate independently of the said spindle and of the extension (1 except as the sleeve 0 is raised and lowered within or with relation to the sleeve e, and consequently only when it 'is desired to rotate the feed-rolls about their supports b If, the said rolls always, however, traveling with and at the same speed as the spindle A When the sleeve 0 is lifted, it, through its diagonal flutes in engagementwith the diagonal flutes of the sleeve e, would lift the latter right along with it; so the sleeve 6 has been provided internally with a small space about and with a shoulder just below the washer a", so that the latter, as soon as the sleeve e has been lifted sufficiently to lug 10 and lever B.

grees; but it is not desired to limit this invention to any particular pitch of the spiral or diagonal flutes,'as that will depend upon the maximum length of the wire to be fed for a fastening and upon the extent of stroke it is convenient to give to the lever B.

The frame-Work as herein shown is bulged or raised to form a chamber in which the yoke a may revolve, the said chamber having a door, F, by which to cover its open face, the said door being hinged at F and having a suitable fastening atF To enable the wire employed (it being taken from the spool 00 to be fed through'thespindle for varying distances, according to the thickness of the stock or leather resting upon the top of the horn and between the horn and the usual rest or plate, j, which bears upon the upper side of the material, the extent of the movement of the feed-rolls about their axes must be automatically varied in accordauce with the thickness of the stock. To do this the shank of the horn has fixed to it an arm or projection, G, to which is secured a rod, G, the upper end of which enters a guide, G the upper end of the said rod serving as a variable stop for the measuring-leg Giwhich is attached by a pin, G (see Fig. 1,) to one end of the lever D. The lever D has (see Fig. 1) a lug, 10, upon which bears the lower end of a rod, 12, having a shoulder, 13, upon which rests a strong spiral spring, 14, theupper end of the said spring'being shown as entering a hole in a chamberedlug, 15, fastened to the head A the said chambered lug receiving an adjusting-nut, 16, which may be turned on the rod 12 to bear with more or less force upon the upper end of the said spring, and thus exert more or less pressure upon the The nut 16 is held in adjustable position by a set-nut, 17. The strength of the spring 14 is suflicient to turn the lever D and lift the yoke D and feeding-sleeve c. If the spring 14 is permitted to turn the lever D farenough to permit the stud D carried by it to fully enter the cam portions of the cam'D", then the said cam will produce the maximum stroke of the lever B, and the feed-rolls will feed the wire a distance equal to the longest fastening to be inserted; but when the material on the horn is less than the maximum thickness then the horn, elevated by the spring B carries up with it the rod G and serves as a stop for the leg G attached to the lever D and as a result I tended through a cap-plate, 16.

shortened, so that the cam portion of the cam D is not permitted to act for its full throw upon the roll D The column A has erected upon it a studscrew, H, upon which is placed a hub, H, of a knee-lever, H having at its inner end sector-teeth 20, which engage like sector-teeth upon a block, 21, secured to the lower end of a rock-shaft, 22, having bearings at 23 24. This rock-shaft has clamped to it a block, 25, notched at its inner end to leave lugs 26, which, as the rock-shaft 22 is turned by the knee-lever, may be made to act upon a toe, 26, (see Fig. 17,) of a stop, 27, pivoted at 28, and turn the said stop about the said pivot when it is desired to throw out of operation or to continue in operation the feed mechanism for the wire.

The measuring-rod G has clamped upon it a foot, 40, shown as a block having a clownward extension, which, when the stop 27 is in one position, is free to enter the large hole in the said stop; but when the said stop is turned to one side, as described, by the knee-lever the said-extension meets the top of the stop, and so long as the said stop remains in such position the lever D will not be moved to feed the Wire. The cam-shaft B derives its motion through a worm, 71, upon the spindle A, the said worm engaging a worm-gear, b fast on the said cam-shaft.

The feed of the shoe is effected bya toothed wheel, m, (see Fig. 13,) the edge of which works against the edge of the sole. This wheel has beveled teeth at its under side, as at m, which are engaged by beveled teeth, as m at the end of a shaft, m extended through a loose box, m the said shaft having a loose washer, as mi, at the rear end of the said box, and having screw-threads, as shown at Fig. 13, upon which is screwed a ratchetrwheel, m having two teeth, which are engaged one after the other by a pawl, m of apawl-carrier, m secured to or forming part of a pinion, m", loose on the rear end of the said shaft m and engaged by sector-teeth 30 (see Fi 1) at the lower end of a lever, m provided at its upper end with a roller or other stud, as m (see dotted lines, Fig. 19,) which roller enters a cam-path, 31, at the rear side of the camhub D". A leather or other friction washer, as m, is interposed between the said washer m (see Fig. 13) and the said box, the said leather washer acting by its friction, measured by the spring m to prevent any accidental movement of the ratchet m, especially when the pawl is traveling through its backward movement. The box on has a hollow hub, 44, on which the feed-wheel turns, the said hub being threaded to receive a screw, 15, ex-

The box m is held in a split bearing, m held together by a clamp-screw, 772 the said box being adjustable longitudinally, so as to place the wheel 'm in proper relation to the top of the horn, according to the distance it is desired to insert the fastenings from the edge of the sole.

Owing to the flutes upon the lower end of the feeding-sleeve being in diagonal or spiral position, it results that the friction between the said feeding-sleeve and the sleeve e, as the said feedingsleeve is pushed down, is sufficient to firmly place the teeth of the clutchsleeve into contact with the teeth of the clutchgear employed to impart motion to the feedrolls, thus preventing any liability of the clutch-surfaces being disengaged except ust as the clutch-sleeve is lifted, as before de scribed.

In the invention herein described it will be noticed (see Figs. 25 and 26, where the feedrolls are shown enlarged) that the projections '21, which enter between the threads to of the wire it to be inserted, a. short piece of which is shown separately in Fig. 27, are exactly opposite each other, and that the spaces in the said feed-rolls between the" said projections r are exactly in line, thus enabling the said spaces to receive the threads of the wire, which threads, as described in United States Patent No. 370,136, are directly or diametrically opposite each other at opposite sides of the wire. In this way the feed-rolls are permitted to have such a firm, secure, and close grip on the wire as to preclude the possibility of the wire slipping or of buckling or bending.

The two bearings I) D for the wire-carrying spindle are connected by a cap-shaped or bonnet-like portion, D and forming part of the rigid frame-work, to which is hinged at F the cover F, the bonnet and cover completely concealing the reel and spindle, thus preventing the creation of a current of air to annoy the operatorwhen the spindle is run at speed; and, further, the motion of reel and spindle, being concealed, does not affect the eye of the operator.

I have herein shown and described certain parts as fluted diagonally and spirally; but I do not desire to limit my invention to any particular form of such flutes.

In the manufacture of the wire-carrying spindle herein described and the parts carried by it during its rotation care has been taken to so proportion the weight of the parts that the spindle is balanced as it is turned, and as a result thereof the spindle may be rotated at a faster speed with less jar than would be possible if the said spindle was not so balanced.
