SPECIFICATION forming part of Letters Patent No. 634,306, dated October 3, 1899.
Application filed September 21, 1898. Serial. No. 691,516. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS F. MORRISSEY, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and usefullmprovementsin Button-FinishingMachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.
The objects of this invention are to facilitate the work of polishing or buffing or otherwise finishing the buttons and by applying them more quickly and regularly tothe polishing-wheel to reduce the cost of manufacture, to secure a more uniform product, to dispense with the use of hand labor to a large extent, to secure the buffing effects by mechanical means only, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.
The invention consists in the improved button making or finishing machine and in the arrangements and combinations of parts thereof, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Fig. 55 is a plan of a pair of levers for operating or controlling a certain slide of the chuck, the said levers being controlled in turn bythe cam of Fig. 3; and Fig. 56 is a front view of the same.
In said drawings, a, Figs. 1 and 2, indicates a suit-able frame arranged on standards or studs Z) b. At one side of the said frame is arranged a bufling or finishing wheel 0 and suitable means for rotating the same, such as the belt and pulley c c, Fig. 1, and at the opposite end is arranged a feeding mechanism comprising a receiver (1, means for ar ranging the buttons in a series or succession, means for feeding them one by one to a hopper p, and an oscillating button-transferring arm or carrier f, adapted to take the button from the said hopper and place it upon the chuck at the upper extremity of a second oscillatory arm 9. The said second vibratory arm 9 comprises a lever 72, fulcrumed at 1' upon said standard Z) near the lower end of said standard, and a spindle S1 for rotating said chuck as the arm it oscillates. Said arm it is given oscillatory reciprocations by a cam 7' (shown in Fig. and a canrgroovej, which receives the trundle j formed or arranged upon the rear side of the lever, as shown in Figs. 1 and 3. The lever-like reciprocating chuck-arm IL is given a movement sufficient to bring the upper end of the chuck 'r from a point where it receives the buttons from the carrier f to the peripheral face of the buffing or polishing wheel 0 and from thence to a point where it enters into engagement with stripping means for removing the said buttons from said chuck and causing them to pass down a suitable way or chute 112 to a receptacle for the finished buttons.
lVhile I have shown in the drawings a detail construction by which I accomplish the results desired, I do not wish to be understood as limiting myself thereto, for I am aware that various modifications of construction may be employed withoutdeparting from the spirit or scope of the in vcntion, and consequently I do not wish to be understood when describing the parts in detail hereinafter as limiting myself by the positive expressions and descriptive terms employed excepting as the state of the art may require. With this understanding I proceed to describe in detail the peculiar arrangements of parts by which I effect the automatic or purely mechanical polishing of the button.
In describing the detail construction I prefer to follow the course of the button through the machine to enable a better understanding of such construction to be obtained.
The unpolished or partly-finished buttons are first inserted in large quantities in the receiver (Z. This receiver and the parts immediately cooperating therewith are somewhat similar in general construction to the one shown in the feeding device of the button-machine shown in my prior patent, No. 547,561, dated October 8, 1805. In my said prior patent the receiver was an open hopper. In the present construction the receiver comprises a spun sheet-metal case (1, the sides of which flare toward the back of the machine and which at its rear edge is provided with a flange by means of which it is fastened by suitable screws or otherwise to a rear plate Z, rigidly secured upon the arm a of the frame of the machine. The said plate Z is inclined, as in my prior construction. The forward part of the said case (1 is open, and the opening is closed at the lower part by a glass plate (1 and at the upper part by a hinged door (7/", the glass plate serving to permit an easy inspection of the interior of the receiver, while protecting the buttons from lint, dust, &c., produced in the polishing operation, the said dust if allowed access to the buttons being detrimental to a proper feeding operation in that it tends to clog the parts and prevent the desired automatic 0pcrations.
At one side of the receiver (Z the same is open or slotted, as shown in Fig. 1, and through the slot the notched periphery of the rotary disk at projects. The said rotary disk on is similar in construction to the one shown in my prior patent, it being also provided atits center with radial ribs (shown in Fig. 14:) for facilitating the turning of the buttons and causing them to properly enter the edge notches, and the said notches serving to receive the buttons, arrange them into a series, and feed them regularly and uniformly to the feeding mechanisms outside of the receiver.
. The buttons entering into the notches the same are carried upwardly within the receiver and thence down-into the slot in said receiver, and from thence the said buttons are fed to the cooperating feeding devices.
The inclined plate-Z, upon which the notched disk m rotates, is provided with a raised margin Z, and said margin outside of the receiver-case serves to hold the buttons within the notches, and a spring guide or keeper 5, Figs. 1, 12, and 14, is arranged in front of the notches of the periphery of the disk outside of the said case, also to hold the buttons in place within said notches. The raised margin Z of the inclined plate at the point from which the buttons are to be fed therefrom is provided with an opening 6, as shown in Fig. 12, through which the buttons pass out automatically by gravity upon the inclined Way or passage 7, formed on the upper face of a bracket 8, when said way is not obstructed by another button lying on said way or by a cut-01f gate 9, lying at said opening, or by an antijamming stop 44, hereinafter to be described.
In my prior device the out-passage opening 6 for the buttons was formed between end walls of the raised rim Zof the inclined plate. At this opening was arranged a spring to prevent jamming; but notwithstanding this spring the buttons when not properly fed were apt to catch orjam, thelimited elasticity of the spring being insufficient to prevent the trouble and in some cases occasioning a damage to the button.
To more perfectly avoid the possibility of injury to the button, I have in the present construction arranged at one side of the button-egress opening 6 of the receiver a movable piece 12, which supplements the raised margin, and being hinged or pivoted at 13 to the end 110 of the raised margin Z extends in the curved line of the said margin to a point about midway of the opening, where at its free end it receives a second hinged piece 14, which latter is raised above and away from the plane of the rib or raised margin Z and supplemental piece 12 to permit of-the passage of the button beneath. The hinged piece 14 is pivoted to the bracket 8 at 15, Fig. 20, outside of the upper end of the margin Z, and at its opposite or lower end it is loosely linked to the piece 12, a suitable slot 160 being provided in oneof said pieces to permit of the desired knuckle action. The hingepiece pin 18 works in said slot and holds the pieces together at their free ends.
The buttons are permitted to pass between the upper end of the margin 1 and the end of the supplemental piece to enter into engagement with a pocket-stop for preventing a direct passage of the button into the hopper the button.
beneath; but should the button because of some abnormal movement or other condition fail to pass through said opening 6 and tend to become jammed in said opening to the injury of the button the abutting free end of the supplemental piece, being only held in normal position by a spring 20, gives under the pressure of the button to prevent injury and sets a train of devices into 0pera-' tion by which the button is immediately returned into its notch in the periphery of the disk d.
Under pressure of the button, as described, the pieces are forced outward and operate a cam-arm 21, which, pivoted upon the hingepin 18 and extending through the slot 16, Fig. 17, receives the spring 20. The said cam-arm when pressed, when the pieces 12 14 are pressed out by the button, is caused to engage a SllClfiOl'pIGSSUPG-PlGCG 19 with an elastic pressure due to the spring 20, and this pressure is sufficient to overcome the pressure of the spring 49 of thepressure-piece and effect a lengthwise movement of said pressure-piece at its slotted end. (Shown in Figs. 20 and 28.) Said pressure-piece at its end opposite that engaged by the cam-arm is pivoted upon the short arm 45 of the leverlike stop or cut-off arm 44 and causes said arm 44 to turn on its fulcrumal pin 40,which is preferably removable, and throw its free longer arm downward into the opening 6 to stop the progress of the button out through said opening, holding said button so that the continued movement of the disk and the bearing at the end of the piece 12 throws said button back into its notch in the disk before injury by jamming is received. Under normal conditions, however, the button is permitted to pass through the opening 6 onto the slideway ot the bracket 7, attached to the receiver; but here its downward gravitation over the inclined slideway is almost immediately stopped by another cut-off or stay 38, hereinafter more fully described.
. To secure a more perfect control of the feeding of the button and to permit of a normal out-passage of the said button from the receiver only when the way is prepared for the same, I provide button stops, gates, or cutoifs, which are controlled by the slide 19 and cam part 21. The first cut-off of the series is the gate 9. This comprises a hooked piece which is pivoted at the back of the receiverplate, as indicated in Figs. 14 and 15. The said gate 9 receives its motion from the upward extension 23 of the slide 22, the said slide having bearings in the bracket 8 and engaging the shoulder or bearing 24 of the said gate and pressing the hooked end inward toward the opening 6, the extremity closing the same, so as to prevent the out-passage of The said slide 22 and its extension 23 are reciprocated by the arm 27, Figs. 1, 12, and 15, pivotally fastened upon a second slide 28, arranged in bearings in the frame a and this slide in turn is reciprocated by a leof the extension 23 is removed.
ver 29, fulcrumed at 281 on the bed or frame (I, and extending downward to the cam j,where the lever-arm of said lever engages a cam projection 291, Fig. 1, to receive its reciprocatory movement in one direction. To receive the return movement, the lever 29 is in connection with a compound lever 31, the members of which are hinged together at 32, the said compound lever being pivoted to the lever 29 at 33, and upon suitable fulcrum 34c, near the foot of the standard I). The lever 3t carries the trundle 35, which engages a camsurface 36 upon the cam j, by which means or by any other means desired I secure an OS- cillation of the lever 29 and reciprocating sliding action of the slide BSand a corresponding reciprocation of the arm 27 and slide 22, by which the gate 9 is alternately opened and closed, the parts being timed to prevent a second button issuing from the receiver while a first one is on the slideway.
Then the gate 9 is closed by the pressure of the extension 23 against it, it is done so against the pressure of a spring 37, Figs. M and 15, which latter opens said gate 9 a limited distance automatically when the pressure The opening of the gate 9 permits an out-passage bygravity of the button from the notch in the disk then coinciding with the opening 6, the button passing out through said opening 6 upon the inclined way 7 of the bracket 8.
The bracket 8 is provided with lugs or bearings 39 39, Fig. 12, which are perforated to receive a removable pin -tO, upon which latter, between said lugs, is pivoted the said cutoff or stop device 38. The body of said outoff device consists of an irregular piece of metal having a fulcrumal bearing to receive the pin 40 and fit between the lugs 39. Said body is bent at one end to give to said body a crank shape, the bent extension 41 serving to receive and be operated by a bearing 42, Fig. 20, of the arm or extension 23 of the slide 22 when the said extension closes against the gate 9, the bearings 23 and 42 engaging, respectively, the gate 0 and the extension 41 simultaneously, or approximately so, thus closing the opening 6 to prevent the out-passage of a button and raising the body 88 of the cut-off from the face of the slideway 7 to permit the button lying back of the said outoff body to drop into the hopper p. At the back of the said cut-off body 38 the same is provided with a suitable downward projection or formation 3811, Figs. 28 and 29, which serves as a stop or pocket for the down wardlymoving button, and is also provided with an adjusting-screw 4-3 for regulating the distance of pivotal movement toward the slideway 7 of the bracket. The body 38 of the cut-off not the engagement of the bearing 42 with the arm 41 of the cut-off body 38 the said outoff body 38 is raised from the way 7 and the button beneath is allowed to drop or slide down said way into the hopper p, where it is turned to lie substantially at right angles to its former position by striking the inclined wall of the hopper as it drops. The bottom of said hopper is slotted to permit the outpassage of the button, the bottom opening being controlled by a slide-valve 50, which is kept normally closed by a spring 51, Fig. 12, the said slide-valve working in a suitable slideway or bracket 52, attached to or formed 011 the hopper. The opening or passage at the bottom of the hopper is made large or small to suit the differently-sized buttons by means of an adjustable plate 54-, arranged within. the hopper and controlled by suitable adjusting-screws 55 50. At its forward end the said slide or valve 50 is provided with a downward projection 53, adapted to be engaged by an oscillating button-carrierf. Said button-earrierf is adapted to oscillate between the hopper p and the button-chuck 1' when the latter is in its button-receiving position, so as to receive the button from said hopper and carry it to said chuck, by which latter the said button is presented to the polishingwheel 0. Said carrier f is operated by the slide 28, which latter is provided with a rack 57 to engage a pinion 59, having a pivotal shaft or hub (50, with bearings in the frame of the machine. Said shaft or hub 60 moves with said pinion and has the body of the carrier fixed thereon, so that said pinion, hub or shaft, and carrier are adapted to oscillate together as the slide 28 is reciprocated by the lever 29, as above described. Said carrier is preferably adjustably fastened upon said shaft or hub (30. A set-screw 61 fastens the carrier to the hub and permits the desired adjustment. Said carrierfcomprises abodyplate (52, to the under side of which is attached or formed a lug 63, providing bearings for the hub and set-screw G1, which lug is formed at the lower end of the said bodyplate (32. At the opposite free end of said body-plate 62 means are provided to receive the button as it drops from the hopper and to hold said button firmly in place at said free end while the carrier makes an oscillation or turns over upon the chuck, the operating parts being timed in their movements, so that the button will be placed in position at the said free end of the chuck by said carrier, the button being forwarded by said chuck to the periphery or polishing-surface, as before described.
Upon the upper face of the reciprocating body-plate (32 are pivoted upon the pin or screw (331 the shear-like grasping-fingers 6t 64, having at their free ends curved flanges 05 05, which together form a pocket or receptacle for the button as it slides from the hopper over the bod y-plate of the carrier, the up per ends of said flanges being separate, as in Figs. 13 and 37, so that when the fingers are spread a passage of sufficient width for the button will be formed, the lower end of the curved flanges serving as stops, preventing further passage, as will be understood.
The said flanges are undercut or inwardly shouldered, as at 651 in Fig. 35, to hold the button in place between the flanges when the fingers are closed and are more or less funnel-shaped or flaring on their concave sides to serve as guides for the chuck to bring the latter into a proper relation to the button when the carrier is turned down upon said chuck. Said flanges are preferably removable from the body of the fingers to permit of an interchange of flanges to suit different sizes of buttons.
The fingers 64 are normally held together by a spring 66 and are spread apart so as to permit the entrance of the button from the hopper by a lever67, Figs. 12, 13, and 34, which is fulcrumed at 68 upon the under side of the body-plate 62 and passing at one end through a slot in the plate 62 is made at its extremity wedge shape, and is thus adapted to enter between the said fingers 64 64 to spread the same apart. Said lever 67 is operated by engaging at its opposite end a trundle 69, arranged on a short stud in connection with the slide 28. As the said slide moves forward with the trundle it turns the pinion 59 in the reverse direction and causes an engagement of the lower arm 671, Fig. 12, of the lever with the said trundle 69 and a movement of the carrier toward the hopper and at the end of the movement an engagement of the carrierplate with the projection 53 of the hopper slide, gate, or valve 50, throwing the latter open simultaneously with the opening of the flanges 65 to permit a passage of the button therebetween. Then the finger-flanges are closed against the button, the latter is pressed a little forward against the shoulders 651 by a pressure-plate 70, Figs. 35, 39, and- 40.
At a point near the free end of the carrier in coincidence with the chamber or aperture between the flanges 65 I have formed an opening for the pressure-plate above referred to. Behind the plate 62 at said opening I have arranged a short cylindrical pocket 71, Figs. 12, 34, and 35, in which is arranged a spring 72, Fig. 35. The pressure-plate 70 is provided at its back with another cylinder 73, which works telescopically in said cylinder 71, the spring 72 lying at one end within said cylinder and at the other against the bottom-of the pocket 71. At the center of said pressure-plate at the back and within said cylinder 73 is formed a shank 74, which extends back through a perforation in the bottom or end of said cylinder 71 and thereat receives a crank-lever 75, fulcrumed upon a stud 76, Figs. 34 and 36, one arm of said lever being loosely pivoted to the outer end of the shank 74 and the other arm providing a bearing for the long spring 77, which last is adapted to engage a bearing 73, Fig. 12, upon the frame of the machine as the button-carrier approaches in its return movements the hopper p. The said spring 77 is of sufficient strength to counteract the power of the spring 72, and is thus adapted to press the pressure-plate 70 back to a position flush with the face of the bodyplate 62 as the button grasping or holding fingers 64 are spread apart by action of the lever 67 The button being released by the opening of theslide 5O gravitates from the hopper onto the plate 62 and enters between the grasping-fingers 64 and over the plate 70, the edges of the button entering beneath the undercut shoulders formed at the inner edges of the flanges 65. between the fingers by gravity, the graspingfingers first close upon the edges of the button and start with the carrier in'its oscillation toward the chuck. Almost immediately the spring 77 passes from engagement with the bearing 73 and permits the spring 72 to force the pressure-plate 70 forward against the face of the button, clamping the latter against the sides of the flanges. The carrier continues itsmovement until the button is brought into contact with the chuck, where said button is caught and held by said chuck in a manner which I will now proceed to describe.
Upon one of the studs or standards 1), near the base thereof, is fulcrumed the oscillating chuck-carrier h. This is given its oscillatory movement, by which the chuck is caused to travel the face of the polishing-wheel, by the cam j, which last is provided wit-h a camgroove 79, Fig. 1, the said chuck-carrier being provided with a suitable pivot j, upon which is arranged a trundle 80, which latter works in said cam-groove, as will be understood. The said lever-like chuck-carrier is provided at its upper free end with bearings 71 h h h 71 for a spindle 81, its sleeve 82, and a spindle-worker 83 for giving longitudinal movement to the spindle, as shown more clearly in Figs. 41 and 42. Said sleeve 82 carries the pulley 84, by means of which said sleeve is given its rotary movement. Within said sleeve it is provided with a suitable key, feather, or spline 85, which works in a longitudinal groove 86, formed in said spindle. The said spindle is thus caused to rotate with the sleeve and at the same time is permitted a longitudinal movement independent of said sleeve. The lower end of the spindle 81 is loosely coupled to the non-rotary spindleworker 83, and the latter is given at suitable times the desired longitudinal movement by means of a system of levers, hereinafter described, operated upon by the cam j-or by any. other suitable means. At the upper end of the said spindle 81 is arranged the check '1', which latter is thus given bot-h an oscillatory movement, by means of which it'is caused to traverse the space between the carrier f and stripping devices, a rotary movement, whereby the button is rapidly turned as it traverses the polishing-surface of the wheel The button having entered ICC c, and a longitudinal movement, by means of l which the said chuck is raised and lowered toward and from said wheel after having received the button from the oscillating carrier. The said chuck is shown more clearly in detail in Figs. 11- to 52. The upper end of the sleeve 82 is provided with a flange or bearing 87, and the upper end of the spindle 81 is threaded, as at 88. Upon said upper end of' the spindle is screwed the body 89 of the chuck, the latter being provided with suitable female threads 801 to receive the same. Around said body portion of the chuck is arranged a sliding collar 00, which has a limited sliding movement. Said sliding collar 90 is provided with a key 90l, which works within a transverse slot or groove S02, Figs. 18 and 49, formed in the chuck-body, by means of which key said collar is prevented from turning on said chuck-body. Said collar is normallyheld at its upper limit of movement on said body by a spring 01.
\Vithin the slot 802 is arranged a sliding block 92, which is suitably pinned to the sleeve 90 by the key 001', so as to slide therewith. Said block 02 is centrally apertured, the aperture 0 3, Fig. 47, having rounded or inclined side walls and opening at the upper end of the block and receiving a pair of crossing or shear-like levers 01 and 95, Fig. 11, which are pivoted or fulcrumed together at 06 and at their lower extremities are arranged within said aperture .13. The upper opposite ends of said shear-like levers are provided with the pintles 07, adapted to enter within the holes or eyes of the button when nearest one another. Between the lowerends of said levers I interpose a spring .18, so that said lower ends or arms have a normal tendency to be spread apart and the upper ends closed together. Thus when the collar 00 is lowered by means hereinafter described the said levers 91 95 will be spread apart at their lower ends by the springOS and the upper pintles will be brought toward one another to enter the buttonholes, and when said collar 90 is relieved of downward pressure and the spring 91 is free to press the same upward the opposite bearings 930, Fig. 4.7, of the block 92 will engage the roundings 0r inclines 90 00 of the levers and press the lower ends thereof together against the power of the spring 98, so that the pintles 97 will be thrown apart against the walls of the buttonholes to clamp the button in position upon said pintles.
The collar 00 is pressed down so as to receive the button by a compound lever 100, Fig. 1, which is fulcrumed at 101 and 102 and has its members pivoted together at 103. Said lever is operated by the cam-wheelj, the cam grooves or projections of which are timed to cause the forked upper end 101 of the lever, as indicated in Figs. 55 and 56, to engage the collar to press the same downward against the spring 91 when the oscillating button-earrierf is in position to receive the button from the feeding devices.
The rotation of the chuck while the latter is in engagement with the button-carrier f lengthwise of its axis of rotation, so that the button is raised at one end of the oscillation to the polishing-wheel and lowered when near the button-carrier f, I employ means for operating the spindle-worker 83, comprising an adjustable lever 105, Figsl, 4-1, and 12, which is fulcru med upon a shaft 106, having hearings in an arm or bracket 107 at or near the bearing h formed or fixed upon the arm or lever ll.
Said lever 105 is in turn operated by cam pro jections upon the cam-wheelj. The said lever 105 is linked at 125 to the spindle-worker 83, so that as the lever turns upward on its fulcrum the worker and spindle are raised with it. The arm 108 of said lever 105 serves to raise the spindle and the chuck thereon upward in a position to receive the button, and the arm 10) serves to raise the spindle to bring the chuck into engagement with the polishingwheel. Said arms are provided with suitable wheels to engage cam-surfaces therefor on the cam j, said eamsurfaces being suitably formed to secure the desired results. After having been raised by the means described and after having traversed the periphery of the polishing-wheel the chuck continues its course away from the feed mechanism a limited distance into engagement with stripping means for removing the button from said chuck. The take-off devices or stripping means are shown in detail in Figs. 1 and 5 to 11, where 111 indicates a fixed fork attached to the chute 112, which serves to receive the sliding collar and press the said collar downward as said collar engages the inclined or curved bearings 113 of said fork near the end of oscillation. As the said collar enters into engagement with the said fork the chuck, where it is provided with the pintles, passes into engagement with a pair of spring-actuated stripping-fingers 111 114, Figs. 9 and 10, which enter beneath the button and force the same free therefrom, so that the said button is caused to slide into the chute, from whence it is directed to a suitable receptacle below. Said stripping-fingers 114 are held together in proper relation to receive the chuck and button by a spring 115.
A suitable guard 116 is provided to prevent the button from being thrown from the chute when released from the chuck.
To permit a free oscillation of the chuck carrier-arm when transmitting rotary motion to the chuck-spindle, I have provided a pair of idle pull'eys 117, asshown in detail in Figs. 5-3 and 54-, which serve in connection with the belt which actuates the pulley 84. Said pulleys are pivoted, as at 118,-npon a slide 119, arranged in a suitable slideway 120 of a bracket 121. As the oscillating chuck-carrier moves backward and forward, as above described, the slide 119 correspondingly slides in its ways, the spring 122 holding said slide in proper relative position and maintaining a uniform or approximately uniform tension upon the belt. By pivoting the pulley-carriers 123 said pulleys 117 are permitted to oscillate in correspondence with the oscillation of the chuck-carrier and the pulley thereon, all as will be understood.
The movements of the chuck carrier-arm h are cushioned by a spring 124:. The lever 105 of said arm his adjusted by means of an adj Listing-screw 126, which is threaded and adapted to engage the cogged extremity of said arm 105, so that said arm 105 may be raised or lowered a greater or less degree, so as to bring the chucks in their operations nearer to or farther from the operating-wheel, the said adjusting-screw thus being adapted to bring the said chuck up -to the face of the polishing-Wheel as the latter wears away.
