BUTTON-ATTACHING MACHINE.

SPECIFICATION forming part of Letters PatentNo. 533,874, dated February 12, 1895.

I Application filed November 1 889. Serial No. 329,377. (No model.)

To all whom it may concern.-

Be it known that I, -W ILLIAM E. ELLIOTT, a citizen of the United States, residing at Marion, in the county of Linn and State of Iowa,

.have invented certain new and useful Improvements'in Button-Attaching Machines; and I do hereby declare the followingto be a full, clear, and. exact description of the invenmatically fed from their receptacles and each fastener threaded through the eye-of a button, the fastener being then driven through the fabric and clinched; and my invention consists in the novel construction, combination, and arrangementof the various parts constitutingmy-machine, and in the novel means employed for taking the buttons and the fasteners attached thereto from the feeding mechanism and attaching the same to the fabric.

In this machine the button hopper used resembles the button hopper of another button attaching machine of, my invention, for which I have filed an application for Letters Patent, dated November 30, 1889, Serial No. 325,600,

and the button feeding and fastener feeding and threading mechanism correspond to similar mechanism in a button machine forwhich a patent was granted to me on August 13, 1889, No. 408,700. This specification is not designed to comprehend through this combination any of the special features set forth and claimed in the abovementioned application and patent. This specification sets forth, however, certain improvements upon devices set forth in the foregoing application and patent, and particularly upon devices set forth in the patent.

' The object of my invention is to produce a machine, which, being supplied with buttonsand suitable fasteners,.will automatically connect said-buttons and fasteners and attach the fasteners to the fabric. This object is attained in the mechanism herein described and illustrated in the drawings which accompanyand form a part of this application, in which the same reference numerals indicate the same or corresponding parts, and in which- Figure 1 is a-front perspective view of my machine, showing the same attached to a suitable table or counter, and in condition for operation.

Fig. 18 is a similar view of the fastener chute, showing the cut-out blade in the extreme upward position. Figs. 19 and 20 are detail perspective views of the fastener chute, showing particularly the slide mounted upon said chute, which slide carries the above mentioned cut-out blade.

In the drawings, 1 is abase or bed plate adapted to be attached to a suitable table or counter 2. To this bed plate is secured a standard 4. which pivotally supports the button hopper 3, a column 7 which supports the driving and clinching mechanism, and abase plate 11 to which is fastened a standard 6, which supports the fastener hopper 5.

The principal features of the fastener feeding mechanism are fully described in my above mentioned patent, No. 408,700. In order, however, that the operation of the present machine may be fully understood, I will again describe this fastener feeding mechanism and its operation. 5, as before stated,is the fastener hopper, supported by the standard 6. The hopper has converging sides, and in it is placed a thin plate 12 which passes through a slot in the bottom of the fastener hopper. A pin attached to the lower end of this plate 12 works in the groove 17 of the standard 6. The bell-crank lever 13 is likewise pivotally connected to the lower end of the plate 12, the pivot working in a slot in one arm of the bell-crank. This bell-crank is actuated by a rod 1 1 connected with an cecentric 15 on the shaft 80, and as the eccentric is revolved and the bell-crank 13 is thereby caused to swing, the pin in the groove 17 is caused to move and the plate 12 is first raised vertically and then tilted about a center coinciding with the opening at. the entrance of the fastener raceway 18. In thus moving upward the plate 12 catches a number of the fasteners or staples, the legs of which straddle its upper edge, and when the plate is tilted the fasteners slide off from the plate 12 into the fastener raceway 18, which, as shown in Fig. 10, is provided with a central ridge registering with the edge of the plate 12, so that the fasteners slide off from the plate on to this central ridge and thence down through the raceway to the chute 19 which is placed at a reverse angle to the raceway, so that the points of the fasteners first strike the raceway.

The improvements in this part of the fastener feeding device over that of my former machine consist in the means by which the fasteners are caused to issue singly from the raceway, and likewise in the means whereby they are caught by the feed finger and inserted through the button shanks. The chute 19 is inclosed by the slide 22, shown most clearly in Figs. 5, 10,17, 18, 19 and 20. This slide is open on top for most of lits length. It is likewise provided with a considerable opening in its bottom, to permit the end of the spring 24 to reach to the mouth of the raceway 18. The slide is provided with a cutout blade 23, which fits closely against the mouth of the raceway. The slide 22 is adapted to slide back and forth over the chute 19,

motion being given to it by means to be hereinafter described. In Figs. 5 and 18 the slide is represented at the upper end of its stroke, while in Figs. 10, 17, 19 and 20 it is represented as at the lower end of its stroke, and in this position the end of the cut-out blade rests against the end of the upper side of the chute 19, so that the cut-out blade is apparently a continuation of the top of the chute. It is not to be confounded with the latter, however. Vhen the slide moves upward the edge of the cut-out blade rises to a point slightly above the top of the fastener raceway 18, allowing a single fastener to drop from the raceway upon a spring 24. carried by the chute 19. In the downward movement of the slide 22 the cut-out blade 23 detaches the fastener from the end of the spring 24, at the same time closing the mouth of the fastener raceway, so that no more fasteners can issue therefrom, and the fastener drops down the chute 19 to a point near the end thereof, where it is caught by the spring 25, the points of the fastener hanging downward.

The end of the chute abuts against the table 20, in which is a groove 21 which forms a continuation of the fastener chute, and which leads to a point where the buttons and fasteners are connected. The slide 22 is provided with a projection 27 at its lower end, see Figs. 5, 19, and 20, and the lower arm of the bell-crank lever 13 in swinging backward strikes this projection 27 and moves the slide upward. The slide is returned to position by the spring 28. The lower arm of the bellcrank 13 likewise carries the device for feeding the fastener forward through the eye of the button. This device consists of a feed finger 29 so pivoted to the bell-crank 13 as to be capable of movement in both horizontal and vertical planes, and provided with a spring which tends to press it upward. The feed finger carries a point which enters the chute 19 through a slot in the bottom of the chute, this slot likewise extending through the bottom of the groove 21. The rear limit of this slot in the bottom of the chute is behind the spring 25. On its forward stroke the feed finger disengagcs the fastener from the spring and carries it forward, pressing downward and out of the way a pivoted guide or switch, 30. The rear end of this guide or switch 30 is much heavier than the front end, so that the front end is normally held against the bottom of the table 20, and when the feed finger 29 moves backward again the guide 80 carriesit downward out of the slot in the groove 21 and when the finger has passed out of the guide 30 it springs up again into the slot in the chute, being thus carried past the fastener held by the spring 25, and into position to feed the fastener forward when the bell-crank 13 again moves forward.

The button hopperS is substantiallythe same as the button hopper described in my above mentioned application, Serial No. 325,600. As previously stated, the button hopper is pivotally supported by the standard-4, and

by means now to be described is caused to swing up and down about its pivot.

36 is an arm pivoted at its upper edge to the support 6. in the groove of the cam 37, mounted on'the shaft 80, so that as the shaft is revolved the arm is caused to swing back and forth.

69 is a bell-crank lever mounted on the pivot of the button hopper 3, and one arm of this bell-crank lever is connected by the link 68 with the arm 36, so that as said arm swings back and forth the bell-crank lever 69 is caused to swing about its pivot. The other arm of the bell-crank lever is adapted to en-' gage with the pivoted dog 70 carried by the button hopper, and as the bell-crank 69 swings about its pivot it strikes this dog and causes the button hopper to rise, against the tension of a spring shown in the drawings. the button hopper of the machine-described in my above mentioned application, Serial No. 325,600, there is also provided means for giving the button hopper a lateral vibration as it swings up and down, consisting, as in I my former machine, of the toothed cam wheel tothe mouth of the button hopper.

buttons.

81 engaging with projections or teeth of the bearing and of the hopper itself, and a spring 82 for holding the hopper and cam wheel close against the bearing. By this means the buttons Within the button hopper are thoroughly agitated during the operation of the the button hopper, being parallel withthe bottom and separated therefrom by a distance slightly greater than the thickness of the heads of the buttons which are being used, and this distance is adjustable, as is hereinafter described, to different sizes of To the rear end of the plate is attached another plate 85, which projects upward, forming the front wall of the button magazine. When the button hopper vibrates in the manner above described, the buttons within this button hopper are thoroughly shaken up and the shanks of the buttons tend to fall into the grooves, and to slide down the grooves. The grooves are somewhat narrower than the breadth of the button shanks, and the buttons therefore arrange themselves with their shanks lengthwise of the grooves. The plate 84 is for the purpose of preventing any-of the buttons'from leaving the grooves after passing out of the button magazine and so falling down and choking the mouth of the hopper. It likewise insures that all of the buttons shall be fed to the threading mechanism in an upright position.

It carries a pin which works- As with The means for adjusting the height of the plate 84-above the bottom of the button hopper consists of an arm 86 attached to the shaft 87, which extends across the button hopper. To this shaft are attached levers which are connected by links 88 to the rear end of the plate 34, and another lever 89 connected by a link 90 with a pivoted bell-crank lever 91 at the narrow end of the button hopper, which connects by means of the link 92 with the front end of the plate 84.. Moving the arm 86 causes the shaft 87 to rotate, thereby raising or lowering the plate 84, according to the direction in which the arm 86 moves.

The mouth of the button hopper 3 registers with the button chute 33 when the button hopper is at the lower end of its swing, and 7 As the buttonhopper nears the lower end of its swing the end of the spring strikes the top of the button chute 33 and is lifted clear of the-mouth of the button hopper, thereby permitting buttons to pass from the button hopper into the button chute. The buttons then slide down this chute, their shanks lying within a groove in the bottom of the chute, to the end of the chute, where they are caught and held by a slightspring 93, shown in Fig. 11.

As above stated, the dog 70, with which the lower arm of the bell-crank 69 engages, is pivotally connected to the hopper 3. One end of this dog is provided with a hooked extension 97, provided with a tapered point, which, when the button hopper is at the lower end of its swing, projects through an opening 98, in the top of the button chute 33. The purpose of this device is to prevent the too rapid feeding of buttons into the button chute, by stopping altogether the feeding of buttons when the button chute becomes choked. Normally, when there are but few buttons in the button chute, the end of the hook 97 will reach nearly to the bottom of the button chute 33; but should the buttons accumulate in the button chute to such an extent as to fill the chute as far as the opening 98, then when the button hopper descends the point of the hook 97 will not be able to descend to IIO the bottom of the chute, but will strike upon upon the head of which the hook 97 is resting will slip down the chute, the end of the book not bearing upon it with sufficient force to hold it in place, thus permittingthe point of the hook 97to fall to the bottom of the chute. When the arm of the bell-crank 69 next rises the button hopper is lifted, as before, and the feeding of buttons into the button chute is again resumed.

The button chute communicates with the groove 91 in the table 20, and from the spring 93 the buttons are carried forward one by one byabutton feeding mechanism which is substantially the same as that described in my above mentioned Patent No. 408,700:

34, is the feed finger, which is pivotally connected to the arm 36, the pivot passing through a slot in the finger 34. The end of this finger carries a hook or button holder 35, having practically the shape of the head of a button, and this button holder is adapted to enter the button chute through a slot in the top thereof, and push forward a button when the arm 36 moves forward. Vhen the finger 34; moves forward, the end passes under and lifts a pivoted guide 38, similar to the guide 30 previously mentioned. On its return movement, however, the linger 3t passes up over the top of the guide 38, the button holder 35 being thus carried up and out of the groove 9st, and when the feed finger has reached the rear end of the guide 38 it drops off and the button holder again enters the slot in the button chute, just in rear of the spring 93, thereby cutting out the button held by said spring preparatory to pushing the button forward again on the next forward movement of the finger 34.

The form of the cam 37 is such that the feed finger which pushes the button forward holds it for an instant at the junction of the grooves 21 and 94 of the table 20, a, at the junction of the button and fastener grooves, while a fastener is threaded through the eye of the button in the manner described in the specification of my above-mentioned patent, No. 08,700. The button is then fed forward by the feed finger into the end of a pivoted carrier or transferrer 39, which is at this moment in the position shown in Figs. 1, 13, and 15, forming a continuation of the button groove 94:. This carrier or transferrer and the means by which it is operated are shown in detail in Figs. 4, 6, 7,1314, 15, and 16. It consists of a block of metal of a generally rectangular shape, pivoted to two downwardly projecting legs of the plunger 40, the length of these legs being such as to permit the carrier to assume a vertical position between them, as shown in Figs. 6, 7, and 14.

Projecting from the side of the carrier 39 is a pin 43 (Fig. 6) workingin the curved slot 42 of the guide 11, which guide is mounted in bearings in the head block 95, and a spring 95, seen in Fig. 1, tends to hold it down. The plunger 10 likewise passes through the head block 95, being suitably guided therein,

and is pivotally connected to one arm of the bell-crank lever 46, pivoted to the top of the column 7. The other arm of the bell-crank carries a pin 50, to be hereinafter mentioned.

Referring now to Fig.3, 10 is a rod passing through the column 7, which rod is attached at its lower end to the foot lever 8 by which the machine is operated. The head 49 of this rod 10 is of the somewhat peculiar shape shown, and is adapted to engage with the pin 50 carried by the bell-crank 46. To this head is pivoted the link 67 to be hereinafter mentioned. Upon the rod 10 is mounted the sleeve 60, the lower end of which is flanged. The sleeve lies partly Within another sleeve 56, which carries the clinching anvil 57, projecting through a slot in the front of the column 7. A spring 69 iucloses the rod 10, one end of the spring bearing against the end of the sleeve 56, the other end bearing against the sleeve 60. Above the sleeve 56 is another spring 59, one end of which bears against the end of the sleeve, and the other end of which bears against the top of the column 7. The anvil 57 is directly below the carrier or transferrer 39 when the latter is in its vertical position.

Within the carrier 39 is mounted a thin driver 51, shown in Figs. 4, 7, and 15. Aslot 52 in the upper side of this driver and a screw 53 working in said slot permit of some movement of the driver within its bearings in the carrier 39. The end of the driver is formed to correspond with the shoulders of the fastener. There is likewise a slot in the face of the carrier 39, which permits of the passage of the shank of the button. In the operation of this portion of the machine, the carrier 39 is first in the position shown in Figs. 1 and 13, with the groove in its face in line with the button groove 9i. The driver 51 is on a level with the shank of the button in this groove 94. The feed finger 34. feeds the button forward from the button groove 9-l tothe carrier 39, the shank of the button entering the slot in the face of the carrier. The operation of the staple feeding mechanism is such that after the staple is threaded through the eye of the button and the button is moved forward by the button feed finger 34, the points of the fastener trail behind, the shoulders being in front. Then the button is fed into the carrier 39 the shoulders of the fastenerstrike the end of the plunger and push it backward, the fastener entering the groove within which the driver works. The legs of the fastener are naturally slightly divergent, and since the groove in the carrier 39 is somewhat narrower than the distance between the points of the fastener the legs of the fastener are pressed together somewhat, the pressure of the legs of the fastener against the sides of the groove in the carrier serving to hold the fastener and button in place and to make it; impossible for the fastener to fall out. During this time the rod 10 has been moving upward, and its head i now strikes the pin 50 carried by the bellshown in Fig. 14.

crank lever 46, thus causing the bell-crank When the movement of the plunger and carrier 39 just described first commenced this pin was at the bottom of the groove 44, and consequently when the plunger rose the pin 45 exerted no effect on the guide 41. By the time the carrier 39'has reached the vertical position shown in Fig. 14 the pin has reached the top of the groove 44, and now lifts the guide 41 against the tension of the spring 95'. The flange on the lower end of the sleeve 60 now strikes the sleeve-56 and carries up said sleeve and the anvil 57 which forms a part thereof. By the time that the'anvil has lifted perceptibly, however, the bell-crank 46 has swung so far asto carry the pin 50 off from the head 49 of the rod 10, so that the plunger 40 is no longer lifted by the bell-crank 46. The upward movementof the anvil 57, however, brings the fabric against the lower end of the carrier 39, and lifts the same with the plunger 40 attached thereto. The upper end of the driver 51 now'strikes the end of a plate 55 held in place within the headblock 95 by a screw 55 and is prevented from rising far- ,ther, and inasmuch as the anvil 57 and carrier 39 still continue to rise, the driver 52 forces the points of the fastener through the fabric and against the clinching die 58 carried by the anvil, and thus causes the fastener to be clinched, the clinching being done, as will be seen, by the direct downward movement of the foot lever. When the foot lever is released the anvil 57, plunger 40, guide 41, and carrier 39 are carried down again by the various springs, and the carrier 39 is caused to swing again into the horizontal position by the pin 43 working in the groove 42 of the guide '41, in position to receive another fastener and button.

Pivoted to the upper portion of the support 6 is the gear wheel 63, and meshing with this gear whee163 is a pinion 62 keyed to the shaft 80, which shaft has bearings in the support 6,

and carries the eccenttic 15 and grooved cam 37. The inner face of. the gear wheel 63 is provided with a ratchet 64,-and a pawl 65 carried by the swinging lever 66 engages with this ratchet. A link 67 pivotally connected to the lever 66 and to the "head 49 of the rod 10 serves to communicate the motion of the rod 10 to the lever 6 and thence to the pawl 65, ratchet 64, gear wheel 63 and pinion 62, thus causing eccentric 15 and cam 37 to revolve, and thereby operating the button and fastener feeding mechanisms.

The operation of my button attachingmachine is as followsz-=When the foot lever 8 is operated its motion is communicated by the means just described to the eccentric 15 and cam 37. Bythis means the bell-crank 13 is caused to swing, raising the plate 12 within the hopper 5 and causing it to tilt toward the raceway. 18. As the plate 12 rises through the fastener hopper the fasteners catch on its upper edge and when this plate 12 tilts the fasteners slide off from the plate and down the fastener raceway 18 to the end thereof, where they are caught and held by the spring 24. While one arm of the bell-crank lever 13 has been raising the plate 12 the other arm has come in contact with the projection 27 of' the slide 22 on the fastener chute 19, and has raised the slide to the upper limit of itstravel. When'the bell-crank swings back again the plate 12 drops, and the spring 28 is permitted to draw down the slide 22. As the slide 22 descends, the cut-out blade 23 depresses the spring:24 sufficiently to permit the fastener heldjthereby to drop into the fastener chute '19 and slide down the said chute, the cut-out blade closing the mouth of the fastener raceway so that but one fastener escapes. The fastener'slides down the chute 19 until'it is caught and held by the spring 25. By the next movement of the bell-crank'13 the fastener feed finger 29 is carried back under the guide 30 and so past thefastener held by the spring 25, and when the finger has reached the end of the guide 30 it springs up, its end entering the slot in the lower side of the chute '19, behind the fastener.

The bell-crank 13 then carries the feed finger 29forward, and as the feed finger moves forward it carries with it the fastener and by this means the fastener is fed to the point of intersection of the button and fastener grooves. During the time that the fastener feeding mechanism has been operating in the manner'justdescribed, the button feeding mechanism. has likewise operated. By the revolution of the cam 37 the arm 36 hasbeen caused to swing. This motion is communicated to the bell-crank 69 by-the link 68, causing the bell-crank to swing about its pivot, and'the lower armof the bellcrank in rising strikes the dog 67 and lifts the same, causing the button hopper 3 to swing upward about its pivot. At the same time that the button hopper moves upward the action of the cam wheel 81 causes a lateral vibration of the button hopper. The double motion thus imparted to the button hopper causes the buttons contained therein to be thoroughly agitated, and theshanks of the buttons drop into the grooves in the bottom of the hopper, thus bringing the buttons to an upright position. The buttons then slide .down the grooves to the mouth of the button hopper and when the hopper is again at the lower limit of its swing and its mouth is consequently in communication with the opening in the button chute 33, one or more of the buttons will be permitted to pass from the button hopper to the button chute, down which they will slide until stopped by the spring 93. The movement of the arm 36 new carries back the button feed finger 34 and the button carrier 35 is carried up out of the groove 94 and so over the button held by the spring 93, by the pivoted guide 38. hen the carrier 35 reaches the end of the guide 38 it drops into the slot in the top of the button chute, thus cutting out a button. Then the arm 36 swings forward again the feed finger pushes forward this button to the point of intersection of the button and fastener grooves 21 and 94, the form of the groove in the cam 37 being such as to cause the button to pause for an instant at this point of intersection. In this mannera button is brought to the point of intersection of the button and fastener grooves an instant before its fastener has been carried by the fastener feed finger 29 to the same point. In the manner described in my above mentioned patent, No. 408,700, one leg of the fastener is threaded through the eye of the button, and the fastener is then turned so that when the button is fed forward by the feed finger 34 the points of the fastener will trail behind. The pivoted carrier 39 is now in the position shown in Fig. 1, the position for receiving a button and fastener. The feed finger 34 now pushes forward the button and fastener attached thereto into the carrier 39, the shank of the button entering the slot in the face of the carrier, while the fastener enters the groove in which the driver 51 works, pushing back the driver. The legs of the fastener, by pressing outward against the sides of this groove, hold the fastener and button in place. During this time the rod 10 has been rising, being carried up by the movement of the foot lever 8. The head 49 of the rod 10 now strikes the pin 50 carried by the bell-crank lever 46, and causes the latter to swing, thereby raising the plunger 40. The rise of the plunger 40, through the action of the groove 42 in the guide 41 and the pin 43 working in this groove causes the carrier 39 to swing into the vertical position. The flanged head of the sleeve now strikes the end of the sleeve 50, and carries it up with the anvil 57, over which is placed the fabric to which the button is to be attached. At the same moment the pin 50 slips off from the head 49 of the rod 10, so that the carrier 39 is moved no farther by the bell-crank 46. The anvil 57 in rising brings the fabric into contact with the carrier 39, so that the fabric is held firmly upon the clinching die 58. The further upward movement of the anvil 57 raises the carrier 39 and the plunger 40 still farther, and the plate 55 striking the top of the driver 51 holds the latter stationary, while the carrier 39 moves upward, so that the fastener is pushed out of the groove in the carrier 39 and is thrust through the fabric and against the clinching die 58, by which it is clinched. When the anvil 57 and plunger 40 again descend the fabric is released and the carrier 39 swings up into position to receive another button and fastener.

It will be seen that this machine automatically adjusts itself to different thicknesses of fabric, to ,which the button is to be attached, inasmuch as the carrier 39 is pushed upward by contact with the upper surface of the fabric.

In order to avoid any possibility of clogging of the machine due to loose fasteners remaining in the groove 94 of the plate 20, I provide a pivoted grate 71, in the bottom of this groove at the point where the fasteners are threaded through the button shanks. The gate is adapted to remain in the position shown in Fig. 8, while the fastener is threaded through the button shank, and to drop when the button is fed forward, thus allowing any loose fasteners to fall through the table. The means by which this is-accomplished is as follows: The under side of the gate is provided with a lug 72, which engages with a similar lug 73 on one arm of the bell-crank 74, the other arm of which is adapted to engage with the feed finger 34 when the latter feeds the buttons and fasteners forward, thus permitting the gate 71 to drop. A spring 75 draws the parts back to the first position after the passage of the feed finger.
