LOUIS GODDU, OF WINCHESTER, MASSACHUSETTS.

MACHINE FOR DRIVING SOLE=FASTENINGS.

SPEOIFICATION forming part of Letters Patent No. 265,227, dated September 26, 1882. Application filed June 10. 1882. (No model.)

To all whom it may concern Be it known that I, LOUIS GODDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Machines for Driving Sole-Fastenings, of which the followingdescription. in connection with the accompanying drawings, is a specification.

This invention is an improvement on that class of machines which are adapted to drive sole-fasteniugs of different. lengths, the longer or the shorter fasteningsbeing driven at will.

In this my machine the fastenings are placed in revolving drums having buckets, which throw the fastenings into chutes, each length of fastening into its own chute, down along which the fastenings, properly held, travel to the separators, which permit their escape separately into the nail-passage and the nose of the machine but those nails the heads of which are not properly held in the chute are picked up by a lifting device and returned to the drum. Each separator, made as a fiat blade,

is forked at its front end to embrace a bar in a plate at the end of the block into which the two chutes merge, to thus avoid forcing a fastening or nail out of the machine through the opening in which the separator works if the end of the separator, when being moved for ward to pass between the said fastening and the end of the chute, should accidentally strike a fastening at its side. The separators are moved by springs actuated by levers under control of a cam and a stop, so that either separator may be thrown out of action at will, thus leaving it at rest in its normal position, at which time it closes the end of the chute and forms one side of the nail-passage in' the block through which the driver descends. The chutes are connected together and with the head of the machine. As herein shown, the head of the machine (it having one bar to which is attached both the awl and the driver) is pivoted so that the head turns in the arc of a vertical circle while the awl is in the stock, thus effecting its feed, and the stock having been fed, the awl lifted, and the stock clamped between the horn and presser, the head is swung in the opposite direction until the nailpassages in the connecting-block of the chutes and in the nose and the driver are brought just above the hole last made in the stock by the awl,after which the driveris thrown down and drivesafastening. Thechutes,connected together at their lower ends and .with the movable head, must slide the drums, and to enable them to be so moved the chutes are held in slots or bearings of loose disks supported in abear'ing between the drums. The machine has also been provided with novel mechanism byv which to depress the horn positively while the awl is feeding the stock. The spring-actuated lever, which depresses the bar to which is attached the driver and awl, is connected with the said bar by means of a link having ball-like or equivalent ends, thus permitting the head in which the said bar works to vibrate in the arc of a vertical circle, and yet be operated by a lever which can vibrate only in the arc of a-circle at rightangles to it.

Figure 1 is a side elevation of thelower part ofthe machine. Fig. 2 is a side elevation of the upper part of the machine. Fig. 3 is a broken detail, showing the annular hub on the stationary frame-work upon which the head is fitted to vibrate, and also the cam for vibrating the said head and the two cams which actuate the separators.

Figs. ..3 and 24 are details of the driverbar and its attached driver and awl. Fig. 25 is a section on the line or, Fig.1 Fig. 26, a section on the line m Fig. 1; Fig. 27, a section on the line a, Fig. 26; and Fig. 28, a sectional detail and top view of the ends of the chutes, separators, pushers, and block, with groove in passage for the nail and driver.

The frame-work A of the machine, of suitable shape to support the working parts, has projecting from its front side (see Figs. 2 and 3) a cylindrical hub or hearing, A upon which is titted and turns the recessed inner face of the movable head B of the machine, a shouldered part, B thereof fitting the hub A snugly, which hub thus forms a fulcrum for the said head during its vibration. The head 13 has a vertical passage to receive in it the driver-bar (t, to which is attached, by a suitable clamp, (1?, blocks, and set-screw a, (see Fig. 23,) the driver a and awl a. The head 1?, :rtits lower end, has connected with it by screw 8 the nose 0, in which is made the vertical passage which receives the nail or fastening to be driven, and into which the driver enters in its descent to drive the fastening. The head B, retained on the hubby screws b in slots 11 has a fork, B, (see Figs. 2 and 3,) in which rests a block, b, fitted upon an eccentric, b, near the front end of the shaft 0, which has its hearings in the framework A, the said eccentric, as the said shaft is rotated. vibrating the head B sufliciently in one direction to enable the awl, when driven down into the stock, to feed it, and in the opposite direction to bring the nose and driver above the hole last made by the awl in the said stock.

The main shaft of the machine has upon it the usual cl utch-pulley, forced together at suitable times by a wedge-block, C of usual e011- 5 struction.

Shaft carries a face-grooved cam, G, that vibrates a lever, G, joined by link 0 with the horn-depressinglever or treadle having its fulcrum at C and connected by a globular jointG, (see Figs. 1 and 26,) with the lower end of the horn-shaft, Z), having at its upper end the usual rotating horn, b, provided with a nail-clinching surface. The horn-shaft has a collar, 1), which rests upon a strong spiral spring, b, the normal tendency of which is to lift the horn against the stock as soon as the feed is completed. The horn is pulled down positively and to a uniform distance below the under side of the stock after driving each fastening, and while the awl is feeding the stock, by means of the pawl d, pivoted on the pawlcarrier (1 guided in guides d, and connected with the rod U, which is attached by bolt (1 with the leverG referred to. This carrier (1 is lifted once at each re olution of the shaft 0 just after the bar a has descended and the awl a is in the stock, and while the head B is being moved to feed the stock, and as the said carrier is raised the pawl (I engages a toothed part of the rack (1 (also held in the guides (1 connected by rod (1 with the horn-depressing lever 0 and depresses the horn. The camblock d disengages the pawl d from the teeth of the said rack as the carrier is depressed, and the spring I) then acts to immediately throw the upper end of the horn against the under side of the stock, whatever may be its thickness. By these devices the horn will always be depressed a certain fixed distance from the under side of the stock notwithstanding variations in its thickness. The operator may depress the horn by the foot-treadle l), pivoted at 0", and having its rear end resting against the lever U at the rear of its fulcrum.

The shaft 0 has a toothed gear, D which engages a toothed gear, 1), on and rotates the shaft 0. The shaft 0 has at its front end a disk, 0, provided witha peculiarshaped crankpin, 0, (see Figs. 3, 4, 7,) which at each rotation of the shalt 0 acts upon the block 0 se cured to the driver-bar a, and lifts the said bar and its driver and awl, withdrawing the driver from the nail-passage in the nose and the awl from the stock before the head B is turned to move the lower end of the nose toward the right, as in Fig. 8, preparatory to driving a fastening, the said block 0" escaping from the said crank-pin c at the proper time to permit the lever 0 under the influence of the strong adjustable spring a, to throw the said bar down quickly to drive a fastening and force the awl into the stock.

The head 0 of the bar (rand the lever are provided with concavities to receive the rounded ends of a link, (i which forms a connection between the said barand 1ever,and which permits the said bar and lever to vibrate at right angles to each other.

The slotted presser b, which bears upon the upper side of the stock, has below it a sliding or adjustable edge-gage, 11 (seen bestin Figs. 17 to 19,) one. part of which has rack-teeth to be engaged by the teeth of a toothed gear, (1 having a handle, d, by which to adjust the said gage horizontally below the presser in proper position to bear against the edge of the stock.

The forward end of shaftO has placed upon it two like cams, f, forming, as shown in Fig. 3, part of a sleeve, which is made to rotate in unison with shaft 0 by means of a pin,f (see Figs. 5 and 6,) extended from the eccentric 1) into a hole in the said sleeve.

The head B hasin it two stops, f f", (see Figs. 15 and 22,) provided with rack-teeth and engaged by a toothed sector. f pivoted atj. One edge of this sector, beveled as shown in Fig. 15, is acted upon by the pointed end of a. holder composed of a spring-pressed pin, f placed in a tube, f having its fulcrum at f. The operator, by turning this tube to the right or left by hand, causes the pin to act on the sector at one'or the other side of its center and force out from the head B one or the other of the said stops to arrest the approach of the arms g of one or the other of the levers g 9, both alike, and pivoted at 2, so that the rollers 3 on the said arms will not be struck and moved by the cams f.

In Fig. 8 the stop f is shown projected to stop the arm of the outermost lever, g, thus retaining out of action the separatorn, which cooperates withthe said lever. The headed nails or fastenings of difi'erentlengths are placed in the two bowl-shaped drums E E, secured to the shaft E held in a suitable bearing, E Each drum has a suitable door or removable piece, It, (see Fig. 10,) through which to introduce fastenings of the desired length, and has buckets h to lift the said fastenings and drop them upon the inclined shelf W. The drums are driven by a train of gearing, h h, and a toothed ring or gear, 7r, which is held against an annular flange, 7L7, at one end of the drum E by friction-plates It, made adjustable by screws h, so that in case of obstruction the gearing may continue to run and the drums stop. The friction between the friction-plates and annular flange h is also made to determine the amount of slippage of the gear Ifand consequent speed of the drums. Fastenings dropped upon the inclined shelf 7L2 fall therefrom upon and into one or the other chute, on or m, both alike, and leading downward to a block, 0", which unites the chutes, the said block having a groove or passage, 10, to receive a fastening, 12, from either chute, the passages at the lower ends of the chutes opening directly into the passage 10 in the block 0 but at opposite sides thereof.

For sake of brevity, I have used the term block to designate that portion of the metal of the chutes which lies between the separators, and in which is made the vertical groove or passage 10 for the reception of a nail or fastening, and down through which the driver dcscends, the said groove serving at times as a portion of the driver-passage; and I wish it to be understood that this so-called block may be either a separate piece of metal or to be integral with the chutes.

The connected chutes have an attached cover, 15, which is joined to the head B by a screwbolt, It, so that the chutes move with the said head. The chutes, near their upper ends, are fitted into mortises or notches madeatthe sides of a flanged disk, m (see Fig. 2,) held loosely in an annular or hoop-like bearing, m supported by or forming part of a bracket, m, attached to a rigid part of the frame-work, the said disk rotating or rocking slightly in its bearing asthc chutes are moved backward and forward in the said niortises or notches, the said chutes deriving their movement from the head B, with which they are connected. The nails or fastenings the bodies of which drop directly into the chutes and the heads of which do not override pass down the said chutes until arrested by the separators n or a, both alike; but those fastening the heads of which stand up for an objectionable distance above the others are acted upon by the forked and inclined forward end of the lifting device n (see Fig. 10,) and are lifted up out of the chute, and as the other Fastenings continue to travel the fastenings so lifted are forced along the auxiliary chute n at the rear of the lifting de vice, and are again discharged into the drum from which they were taken. The majority of the loose fastenings piled upon each other in the chute will be knocked off by the knockingofl' finger n, composed of a piece of bent wire, the lower bent end of which terminates just above the top of the chute, as shown in Fig. 10. The covering-pieces n of the chutes on m restjust above the heads of the nails and prevent them overriding as they approach the block 0".

The separators (made as fiat blades, one of which is shown clearly in Fig. 21, and arranged at opposite sides of the block 0", between the said block and the ends of the chutes, to stop, when desired, the passages between the said chutes and the said block 0") are slotted or forked at their front ends, as shown in Fig. 21, and when projected forward to cover the ends of the chutes straddle a bar, 0, left between two short vertical slots made in a plate,

0 attached to the face of the block 0*. The separators may have severalslots to co-operate with bars 0. Forking the separators, as described, and making them pass over the bar 0 obviate the liability of a nail or fastening being struck at its side by the end of the separator and being driven by the separator into the slot in the plate 0 through which the separator works, for the said slot above the bar 0 is shorter than the shortest fastening.

Theeudmostnails of the rows of loosely-held nails in the inclined chutes, down which the said nails travel by gravity, are kept pressed closely against the separators, when forward, by their own weightand thejar of the machine, produced chiefly by the blows of the driver,

IIO

the pashers being at that time held back, as in full lines, Figs. 20 and 28. A nail will be transferred from one of the said chutes into thegrooveorspace 10 between them only when the driver is down and partially fills the said space.

The separator at the end of that chute containing the nailnextto the driven will be pulled back to uncover the end of thesaid chute while the driver is in its lowest position, and as the separator uncovers the end of its chute the arm will pass from the block 1) (see Fig. 20) and permit the pusher p to act upon the loose nails near the end of the chute and crowd the endmost nail ot' the series of nails, which endmost nail rests closely against the said separator, as before described, and push the said nail against the side of the driver, there being suflicient space at the side of the driver and between it and the reduced end of the separator then drawn back for the reception of but one of the said nails. The nail having been pressed against the driver, the separator commences its forward movement, placing its thin beveled upper point between the nail resting against the driver and the next one back of it and close to the head of the said nail, after which the pusher is retracted. The separator, as it continues its forward movement, actuated by a spring, as will be described, and as the driver rises, gradually brings its thicker portions behind the endmost nail,and the beveled surface, being at the side of the separator next the driver, gradually straigh-tens the said nail, bringing it into upright position by the time the driver is lifted from the opening 10, the separator, by its thicker part, gradually reducing the area of the opening 10, and when both separators are fully forward they form the side walls ofthe said space10, into and through which the driver next descends to drive the said nail. The pusher will act on a nail more or less remote from the endmost nail. The block 0* is held with its groove or passage 10 just above the nail-passage in the nose 0, so

that a nail or fastening removed from one of the chutes after the withdrawal of the separator next to its end will drop into the nailpassage in the nose 0 under it.

Each separator is connected with a slide, a, guided between the metal pieces constituting the chutes, (see Figs. 20 and 21,) and is reciprocated by means of a spring-rod, n extended down through it. These spring-rods are moved backward one at a time to Withdraw the separators, so as to uncover one end of one or the other nailehute by means of one of the levers y or y as it is moved by its connected spring 13, the said lever, when so to operate, not having its arm arrested by the stop f orf, but rather having its roller 3 on one of the camsf. As the lower end of the lever g or g is moved toward the left (see Fig. 8) it acts against one of the rods 01. and causes 'it to draw that one of the separators back which is to nncoverthe end of that chute from which the nail is next f of the holding device.

to be taken, when the endmost nail,12, of the row of nails therein will be moved by the pusher beyond the separator into the groove or passage 10 of the block c",and against the driver, as described. A nail having been passed into the said passage, the cam f acts on the levergor g,controlling the said separator, and turns the said lever in the direction to permit rod of to move the separator to close the end of the chute from which the said nail was just permitted to escape but during this forward movement, it the end of the separator should strike a nail, the spring-arm a will prevent breakage.

Either lever g or g may be oper ted at will to move either separator at each rotation of the main-shaft and permit the escape of a nail of the desired length from one or the other chute by withdrawing the stop/' orf, which is done by the change of position of the tube The levers gg have connected with them arms g", the lower ends of which, as the levers are vibrated, strike inclined blocks 1;, secured to arms p held in movable blocks 1) and acted upon by springs 1). The forward ends of the arms 17 have pivoted to them the pushers p acted upon by coiled springs 1), (see Figs. 20 and 21,) which serve to normally keep the said pushers with their ends pressed against the inclines 15 near the slots in the chutes. (See Figs. 20 and 28.)

Vhen a lever g or g is not in operation the arm y will act on a block 1) and keep the pusher back, as in full lines, Fig. 20; but as a separator is moved back to uncover a chute theartn is moved to the rear of the said block and permits the arm 11 and pusher to belnoved forward into the dotted-line position, Fig. 20, and push toward the groove or passage 10 in the block 0* the nails in advance of it; but only one nail can pass beyond the separator and between it and the driver, and the driver, as it is again immediately moved forward, enters between the nail in the passage 10 and the next one to it at the end of the chute.

The delivery ends of the chutes are curved so as to allow the headed nails or fastenings ot' diflcrent lengths to come directly into the said groove or passage 10 at its opposite sides, the chutes supporting the said nails by their heads until a separator beveled at its end passes behind the nail next to the driver. The end of each blade-like separator (see separator a, Fig. 22) is beveled at one side, commencing at its upper edge, and the said bevel decreases toward the lower edge of the separator.

Each separator is placed at an incline, as in Fig. 21, so that its thin beveled upper point will readily enter just behind the endmost nail ot' the chute, close to its head, and as the said separator is moved forward its wedging end and face next the driver will act to place the nail next to be driven in upright position in the passage 10.

The force of the spring 0 is controlled by turning the disk w, with which one of its ends is connected. This disk has worm-teeth atits periphery, (see Figs. 2 and 8,) to be engaged by the worm r on a shaft provided with a hand-wheel, 1' and held in an ear, 1', fast to the frame-work.

Whenever the horn is depressed by the operation through the foot-lever the rack-bar d is lifted but the teeth of the said bar are not worn by such movement, because the pawl d is supported by the stop or cam (1 In case a nail should happen to lodge on the ehute crosswise under the heads of nails held in the chute, the said nail, as it reaches the open space below the pickingup device 01 (which at this point is beveled and made thin, as at r, Fig. 10*, as is also the top of the chute at T2,) will, as it; meets the corners or shoulders r at the lower side of the picking-up device, be tipped in one or the other direction and be thrown off the chute.

It sometimes happens that a nail will stand with its head upon thechute and with its shank upright. The shank of such a nail will enter between the forked ends of the picking-up device it not removed by the knocking-oft device a; but as the said nail reaches the open place r at one side of the picking-up device it will tip over and fall back into the drum.

The small shoulders 4, formed by beveling the top of the chute under the picking up device and near the shoulders r, as the chute is moved longitudinally with the movable head, as described, will strike against the beveled under side of the head of a nail lodged crosswise and will move it en-dwise from the top of the chute.

The outwardly-beveled edges We of the picking-up device and chute deflect outward the points of any nails striking against them, and only nails having their heads properly supported on the chute can enter the groove 1 at the under side and rear part of the picking-up device, which part serves as a pirt-ot' the cover for the chute.

Nails having small imperfect heads, as well as slivers, sometimes get lodged into the chute and travel along the chute between the perfect nails. To dispose of these imperfect nails and slivers,the space between the walls of the chute is made wider towards its bottom, (see Fig.10,) so that the said nails and slivers gradually drop as they descend the ehute,-an d one side wall of the chute is cut away, as shown at m", Fig.8, to at that point permit the said imperfect nails and slivers to readily fall out and outside of the drum.

I do not broadly claim the swinging head and awl to feed the shoe as the head is being vibrated or swung.

I do not claim a pivoted laterally-movable raceway provided with two channels for nails, the raceway being movable to place one or the other channel opposite the stationary nailguide.
