SPECIFICATION forming part of Letters Patent No. 455,552, dated July 7', 1891. Application filed November 3. 189d- Serial No. 370,177. (No model.)

To all whom it nutty concern.-

Be it known that l, EDWIN D. WELTON, of

NVaterbury, in the county of New Haven and 'and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a top or plan view; Fig. 2, a side I view looking from the left of Fig. 1; Fig. 3, a front View; Fig. 4, a side view of one of the studs which the machine is adapted toset; Fig. 5, a vertical central section of the same; Fig. 6, a sectional view cutting on line 00 0c of Fig. 3, looking to the left and illustrating the mechanism for imparting rotation to the hop per-fingers; Fig. 7, a vertical central section on line 00 0c of Fig. 6; Fig. 8, a detached longitudinal sectional View of the hopper, illustrating the delivery of the studs from the finger in the hopper to the conductor leading from the hopper; Fig. 9, adetached face view of the hopper, showing the conductor and guard and also illustrating the operation of the fingers within'the hopper; Fig. 10, a longitudinal section cutting in a vertical central plane through the setter, showing sectional side view of the slide h, the partsbeing in the normal or stud-receiving position: Fig. 11, the same as Fig. 10, showing the mechanism as having delivered the stud to the setter; Fig. 12, alongitudinal sectional view showing the cams on the drivingshaft; Fig. 13,.a transverse section illustrating the mechanism for operating the setter, and Fig. 14 a detached top view looking down upon the setter and the hook-slide.

This invention relates to a machine for setting that class of lacing-studs which consist of a tubular shank having a hook upon its outer end, the shank being substantially an eyelet, and so that when set through a corresponding hole the metal of the shank is .upset upon the reverse side, as in the case of I an eyelet, and so as to firmly secure the hook,

these hooks being specially adapted for the lacing of boots. and shoes, one of such hooks being shown in Figs. 4: and 5, the object of the invention being the construction of a machine into the hopper of which a mass of such hooks may be placed and be successive- 1y delivered therefrom to a setting device, the

. maybe supported in any suitable or convenlent manner; B, the driving-shaft, supported in suitable bearin gs, to which power is applied to impart revolution thereto from a pulley C. This pulley is preferably loose upon the shaft, and a clutch D is arranged on the shaft, combined with a lever E, by which the clutch may be thrown into engagement with the Wheel, so that the wheel will be coupled with the shaft or disconnected therefrom, as may be requireda common expedient in automatic machinery for applying or disengaging the power.

F 'represents'the hopper, which is supported upon a bracket G, stationary upon the top of the bed A. The hopper has an opening 11 in the top, and, as here represented, this is closed by a hinged cover I, as seen in Figs. 7 and 8. The hopper is of substantially cylindrical shape, the axis being horizontal. In axial line with the hopper a shaft J is arranged in the bracket G. This shaft extends into the hopper and carries several fingers K K. These fingers preferably project from a disk L, made fast to the shaft J; but in any case the fingers are adapted to revolve with the said shaft J. The fingers K are of blade-like shape-that is, they are of thin metal seinewhat less in thickness than the opening in thehook-and they stand upon an incline to the axis of the hopper 'and shaft J," so that when one of the fingers is in the up position, as seen in Fig. 8, it will incline downward from the shaft side to the opposite side of the hopper, and at that time the finger is substantially vertical.

A mass of studs is placed in the hopper and the fingers rotate through the mass, and each plane of' the IOO ' through opening M finger in such revolution through the mass will enter the open side of one or more hooks and so engage the hooks that the hooks thus engaged will be taken by the finger and carried upward to the position seen in Fig. 8, several studs being represented as upon the finger, and the inclination of the fingers with relation to the axis upon which they revolve is such that they will slide from the finger, if permitted so to do, by their own gravity. In revolving, as seen in Fig. 8, the finger comes into line with an aperture M through the side of the hopper, and through which the studs on the finger may slide, so as to escape from the finger. From the opening M a guide or conductor N ektends, this guide presenting an edge like the edge of the finger K and in line therewith, so that the studs passing through the opening M in the hopper will run directly onto the said conductor N, and this conductor leads to the point where the studs are to be set.

An intermittent rotation imparted to the shaft J and the fingers K, which it carries, and so that as one of the fingers reaches the opening M, as seen in Fig. 8, the shaft will remain stationary for a predetermined length of time, and so as to permit the studs to pass from the finger through the opening M onto the conductor N. Such intermittent rotation of the fingers is produced from a cam-groove.

O in the cam 12 on the shaft 13. Loose on the shaft J is a collar P, and this collar receives an oscillatory movement from the cam O a lever Q, connected to the said disk by a rod R, (see Fig. 6,) and so that in the rotation of the shaft B an up-and-down vibratory movement will be imparted to said lever Q and a corresponding osci-llatory'movement imparted to the collar P. The inner face of the collar P is recessed, and within that recess is a toothed ratchet S, made fast to the shaft J, and in a recess T in the collar P in the plane of the ratchet S is a pawl U, (see Fig. 6,) which is adapted to engage the teeth of the ratchet S.

' A limited amount of friction is applied to the shaft J, as here represented. This is produced by a nut V, screwed onto the shaft against the side of the bracket opposite the disk L, and so that by the turning up of the nut the requisite friction will be produced. As the collar P advances under the rise of the lever Q and the engagement therewith of the pawl U it will impart a corresponding rotation to the shaft J, and this rotation is sufficient to advance one of the fingers to the up position, as seen in Fig. 8, while others are passing through the mass of studs below, and when the finger presenting the studs has beenthus brought to its up position the pawl U is free to return under the action of the cam 0.

It is necessary to successively arrest the fingers in a position corresponding to the and the conductor N, so that the with certainty slide from the finstuds may ger so presented onto the conductor N.

thus arrest the fingers, a dog WV is hung upon a stationary pivot X, (see Fig. 6,) which is adapted to engage the teeth of a second ratchet Y, made fast to the shaft J, and the position of this dog W with relation to the teeth of the ratchet Y is such that each tooth of the ratchet Y will engage the said dog when the up position of the fingers is reached. Therefore the number of teeth of the ratchet Y should correspond to the number of fingers in the hopper. The dog W is yieldinglyheld against the ratchet by a spring Z.

The operation of thedog WV and the ratchet Y makes a positive stop when a predetermined position of the fingers is attained,and the dog being arranged, as here represented, upon the side opposite the pawl U, the shoulder or working edge of teeth of the ratchet Y is in the opposite direction to that of the teeth of the ratchet S, upon which the pawl operates. Because of this dead-lock of the shaft and fingers it is necessary to mechanically throw the dog I out of engagement with the ratchet Y before rotation of the shaft commences. Normally the dog WV stands out of engagement with the ratchet Y, as represented ,in Fig. 6, and it is thus held by means of a concentric slot 0. in the collar P, in which a stud b on the dog V rides. At the end of the said slot a toward the pawl the slot is turned inward toward the ratchet, as at d, and so that as the collar P rotates under the action of the pawl 'U, as before described, the dog WV will be held out of engagement with the ratchetY during the time of passage of the concentric portion of the slot a over the stud b of the dog W; but so soon as the turned-in portion of the slot reaches the stud b it permits the dog W to spring inward, and this inward movement of the dog brings it into position to engage the next advancing tooth of the ratchet Y, and so as to certainly arrest the rotation of the ratchet when the tooth engages the said dog and as represented in broken lines in Fig. 6. Then when the collar P, with the pawl U, returns the turned-in or cam-shaped portion d of the slot at forces the dog WV outward and away from its engagement with the ratchet Y and ready for the next advance movement of the pawl U, the friction upon the shaft J being sufficient to prevent the return of the shaft withthe returnof the collarP. Bythisarrangement of mechanism the fingers in the hopper willbe successively presented to the opening M for the escape of the studs, which may be taken by the fingers through said opening onto the said conductor N. It is of course necessary that the studs should be presented with their shanks all in one direction, and this is accomplished by causing the fingers to run so close to the bottom of the hopper that they can only engage studs which are presentedwith their shanks upward and with the open edge toward the fingerybut there will always be more or less of the studs in the hopper presented to the fingers as and the arrow in that figure indicates the direction of rotation, it being understood that the vertical plane of the conductor N corresponds substantiallywith the vertical plane of the finger when it is presented thereto,

and so that the conductor forms practicallya continuation of the finger.

It at any time the conductor should be so full of studs that all presented by a finger into line with the conductor could not escape through the opening M onto the finger, there would be a liability of" the foremost stud on the finger projecting so far from the finger as to strike the side of the opening M when the finger commenced its next advance step. To prevent such clogging, a deflector d (see Figs. 8 and 9) is arranged in the opening and operates upon that side of the opening toward which the fingers are revolvingthat is, the upper side-and presents a curved or camlike surface, against which the foremost'stud on the finger will strike as the finger advances and operate to press the studs backward onto the finger and out of possible reach of the side of the opening;

' Upon the inside of the hopper a concentric recess 6 (indicated in broken lines, Fig. 9) is formed in the plane of the path of movement of the end of the finger and of a depth sufficientto permit a stud to escape from the finger should it turn forward onto the end of the finger in passing the opening, this being an additional precaution against possible clogging. Over the conductor N and following'the line of its upper or guiding edge a corresponding guard fis arranged, which serves to hold the studs on the conductor-or prevent their accidental escape therefrom. The conductor N starts from the hopper in a vertical plane, but is twisted, so that when it arrives at the place of setting, as seen in Fig. 9, it stands in a horizontal plane, and so that the studswill be presented with the shank in a vertical plane shank upward. One of the studs isshown on the conductor at gin Fig. 9, and the end of the conductor is shown in Fig. 10,in which the stud g is represen ed as havingescaped from the end of the conductor.

A slide h is arranged in suitable guides 2' on the bed and so as to reciprocate in a plane at substantially right angles to the delivery end of the conductor. (See Figs. let and 10.) A reciprocating movement is imparted to this slide it by means of a cam-j on the shaft B through a lever 76, hung upon a pivot Z and connected to the slide 7L by a link m. The

. cam operates upon the slide h positively to produce the rear movement, and a spring it operates in. conjunction therewith to produce the'forward or advance movement of the slide This slide is represented in Fig. 10 as in --its eXt'reme rear position and in Fig. 11 in the advance or forward position. A t the forward end of the slide" a slotted projection o is formed,the plane of the projection correspon ding substantially to the plane of the. under side of the head of the stud as it comes from the conductor N, and so that the stud may pass from the conductor N onto the projection 0. This projection 0 forms a seat upon which the stud may rest. Upon the upper side of the slide it a hook p is hung upon a pivot r, so as. to swing in a horizontal plane. Then the slide is in its rear position,as seen in Figs. l l and 10, this hook p stands directly in the path of the shank portion of the stud, and so that as the forward stud passes from the conductor onto the seat 0 the shank of the stud will pass into the embrace of the hook, as seen in Fig. 10, and sothat the hook will be supported in an upright position on the seat,

a vertical slide t, and which normally stands in the plane of the opening in the stud as it is presented by the slide h, and as seen in Figs. 10 and 11,but so that after the stud has been so presented and placed upon thev sett er s a vertical movement may be imparted to the said setter. As the stud has been thus placed upon the setter the slide h returns;

but before such return of the slide it is necessary that the hook from the stud.

To automatically disengage the hook from the stud, the hook is constructed with an arm u, projecting laterally therefrom, and on the bed or some part of the machine is a stationary stud 1*, forward of the arm to and in its path and in a position with relation to the said arm that as the hook approaches its extreme forward position it will strikethe said stud Q; and turn the hook away from the stud, as represented in broken lines, Fig. 14, thus clearing the hook from the stud, so that the slide and hook may return, and as the slide and hook so return. the arm it strikes another stationary stud w, and so .as to return the hook, as represented in Fig. 9, preparatory to receiving the next stud. The vertical reciprocating movement is imparted to the slide't, which carries the setter, by means of a cam-2 on the shaft B. (See Figs. 12 and 13.) The setter-slide t is connected to a link 3, which, with the link 4, forms a toggle. From the joint of this toggle a bar 5 extends to the. canrand so as to be operated thereby, as indicated in Fig. 13, and so that under the-rotationjof the cam the toggle will'be operated to force ,the slide t upward, as seen in broken lines, Fig. 13, or draw the said slide downward.

To hold the stud firmly upon the setter and prevent the possibility of accidental disengagement, a dog (5 is hung upon an axis 7.in

p should 7 be disengaged the slide tbelow the setter s andsoas tovi-.

brate in a back-and-forward vertical ptane.

The upper end of this dog is constructed with a recess 8, which corresponds substantially to the head of the stud. Normally the upper end of this dog stands to the rear of the setter 3, as seen in Fig. 10; but as the slide h advances the slot in the seat permits the seat to pass forward, one portion each side of said dog, and so as to bring the head of the stud into the recess 8 in the dog, then the slide strikes the dog, so that the dog then moves forward with the slide and stud as the stud passes onto the setter s and until the final position is reached, as seen in Fig. 11. As the dog then stands, the stud is practically looked upon the setter, and the slide retreats and leaves the dog and stud in that position. To hold the dog in this locking position, a spring-follower 9 is arranged in the set-terslide t below the dog, and the lower end of the dog is constructed with two seats 10 and 11 oblique to each other. The one seat 10 rests upon the follower 9 when the dog is in the rear or receiving position; but as the dog is turned, as before described,to the position seen in Fig. 11 the seat 10 passes from the In so doing it operates as a cam follower 9. to depressthe follower, and then as the dog reaches its extreme forward position the seat ll is brought over the follower, which rises to meet that seat, as seen in Fig. 11, the springfollower offering sufficient resistance to the turning of the dog to hold it in either position. After the stud shall have been set, as hereinafter-described, the dog is returned by a cam 12 on the shaft B,operatingaslide 13, arranged to move backward and forward in the plane of the dog through a lever 14:, hung upon an axis 15. (See Figs. 2 and 10.) This cam normally holds the slide 13 in its rear position. The lever 14 is provided with a spring 16, the tendency of which is to force the slide forward, and at one point in the cam 12 is a recess 17, into which the cam end of the lever It may drop, and in so dropping the slide 18 will be advanced, as seen in Fig. 11, and so as to strike the lower or tail end of the dog and give it its return movement.

Over the setter s and in line therewith a setting-anvil 18 is arranged. This anvil, as he re represented, is a spindle supported in a vertical position in a head 19, stationary in the bed of the machine, and is preferably made adjustable in the head 19. As here represented, this adjustment is produced by a screw 20, and when the adjustment is made is held' by a lock-nut 21. The face 22 of the anvil 18 is shaped substantially like the face of an eyelet-setting punch or anvil, and so as to enter the tubular shank of the stud and throw the metal outward and toward the base of the stud, and so as to clamp the material upon the stud in the usual manner. The stud having been delivered to and received by the setter, as before described, the material to which the stud is to be attached having been punched accordingly is placed over the shank of the stud, and then the setter rises and takes the stud and material upward to the anvil, where the setting is perform ed. The setter and material then returning, the material with the stud thereon is removed, a second stud delivered and in like manner set, and so on, the studs being successively and automatically delivered and set.

Vhile I prefer to produce the setting operation by employing astationary anvil and moving the setter to it, the setter may remain stationary and the anvil be moved upward and downward to produce the setting-that is to say,-the reciprocating movement may be imparted to the anvil orsetting-punch 18 instead of to the setter s-such reversal of the movement being so common in eyelet-setting machines as to be too well known to those skilled in the art to which this invention pertains to require particular illustration and description.

For convenience of clearing the hopper, an opening is preferably formed near the bottom of the hopper and a removable cover 23 is applied thereto, as seen in Fig. 7.
