BUTTON-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 491,016, dated January 31, 1893.

Application tiled February 23, 1892. Serial No. 422,336 (No model.)

To @ZZ whom it may concern:

Be it known that I, FRANK E. HALL, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Button-Setting Machines, of which the following is a full specification.

My invention relates to machines for setting buttons of the class wherein the two main parts of the button are riveted together through the material, my improved machine being automatic in its action and adapted to feed both parts from separate hoppers to the point of clinching, in the manner hereinafter set forth in detail.

Referring to the accompanying drawings:- Figure l-shows in side elevation, partly in section, a machine embodying my invention, the section through the upper hopper being taken in the plane of z z Fig. 5. Fig. 2-is a front view of part of the plunger casing with a portion thereof shown in section. Figs. 3 and l-are sectional views on an enlarged scale through the two chutes for feeding the button parts, the two parts being each shown in its respective chute. Fig. 5-is top plan view of the machine and Fig. 6 is a horizontal sectional view in the plane of x :c Fig. l.

A is the standard of the machine and A the base plate thereof screwed at a to the table B near the front edge of said table. The upper branch of the standard A terminates in front at A2 in a shell or casing for the upper stationary die I, while the lower branch of the standard terminates in front in the plunger casingA3 which extends downward, below the table.

H is the plunger guided to move up and down in the opening within the casing A3. The plunger is bifurcated at its lower end as at h and pivoted at n to the connecting arm N which is in turn pivoted at n. to the lever P fulcru med at p to the bottom of the plunger casing.

P is a rod connecting the lever P to a suitable treadle all parts being so arranged that an up and down motion is imparted to the plunger H when the rod P is moved up and down, the arm N playing in the slot a4 at the back of the plunger casing.

C and D are the two inclined hoppers which ratchet by means of the spring d?.

are to contain a quantity of the butt/on tops and washers respectively. The hoppers are mounted in the anges C7 D7 which are integral with the brackets C and D respectively, said brackets being screwed or bolted to the standard one on each side thereof, and C2 and D2 are the hopper covers. .l

C4 is a shaft having bearings in the bracket C near the outer end thereof. C3 is a plate set into the flange C7 and xed on the shaft C4 to turn therewith. The top of the shaft C4 is screw threaded as at c4 to engage with the central tapped opening in the hub o3 of the hopper O. The hopper is thus tightly screwed on the plate O3 with which it turns.

The various parts of the hopper lD with its ,i

connections are precisely similar to the corresponding parts of the hopper O.

Fig. 6- best shows how motion is transmitted to the hopper D. D4 is the shaft (corresponding to the shaft O4 of hopper C.) mounted in the bracket D. D5 is a ratchet wheel fixed to the shaft D4 near the bottom thereof, while D6 is a disk or plate mounted loosely on the shaft D4 beneath the ratchet wheel, and provided withan arm D8. d5 is a the ratchet wheel, being pressed against said tent to prevent the backward turning of the shaft D4.

E, E', E2 is a double bell-crank lever ful crumed at e to the standard A. To the two arms, E E2 of this lever are respectively pivoted at e e2 the rods E3 E4 the rear ends of which rods are pivotally connected at 06d respectively to the outer ends of the ratchetactuating arms C8 D8. The outer end of the arm E is pivoted at e3 to an end of the bar M which bar passes through the slot b in the table B and is pivotally connected at h3 with the arm H3 rigidly secured to the plunger H. Thus as the plunger H rises and falls the arm H3 moves up and down 'in the side slot a3 of the plunger casing, and through the bell-crank and ratchet-and-pawl mechanism just described, a step by step motion is given both IOS with the openings cof a size and shape to allow one button at a time when in proper position to pass out.

F is the raceway for the button tops lthe transverse section of which raceway is shown in Fig. 3. This raceway F is preferably made in one piece and is connected at its upper end with the flange CT near the lowest point of said flange in such a position that the open slot wayfis uppermost but takes a twist in its course downward and terminates under the stationary die I with the slot way f beneath. The raceway F is held at the'bottom by means of the piece F screwed thereto and to the standard A. As the hopper C moves around, the button tops contained therein are stirred and agitated,being constantly dropped to the lowest point thereof in such position as to emerge through one of the openingscat frequent intervals, whence they pass into the raceway FV with their riveting eyelets R pointing upward, and dropby gravity to the,

lowest point thereof, said riveting eyelets R atthe bottom of the raceway pointing directly downward. A spring linger F2 at the bottomot the raceway prevents the lowermost j button top from passing out of the raceway, and keeps it under the die I.

It is intended to keep the raceway F constantly full of' button tops from top to bottom, the lowermost buttontop having-itshead immediately under the stationary die I. This isheld in its socket by means of the set screw. i, and may be lowered when desired by the screw I at the top.

G isthe raceway for the button washers S, presenting in transverse section the shape shown in Fig. 4, having the top plates G screwed thereon at g. Thisraceway passes directly down from the hopper Dcontaiuing the washers, to the plunger casing A3 with the interior of which the raceway connects.

The hopper lD has the openings d of such a shapethat the washers can only emerge therefrom with the open side u p. The washers, as:

shown in Fig. 4 contain anvils for clinching the riveting eyelets R therein.

The plunger easing A3 is provided with a transverse slot way in line with the raceway G passing across-the width ot the plunger dpening and communicating therewith, and passing through the side projection H4. In this slot way is guided the horizontally sliding, gate L beveled at Zzatits forward end and havinga downwardly bent armwith a roller L at they bottom thereof.

H2 isa cam shaped arm secured to theplunger and projecting laterally through the slot a3 in such a position that when the plunger rises the cam shaped arm engages with the roller` L and moves the gate L outward thereby opening communication between the raceway G and the interior of the plungercasing. By means of the spring Z and the post Z the gateL is moved backward into the position shown in Fig. 2, closing communication beplunger is in the lowest position lies just loe- ,low the gate Lso. that a washer passing from the raceway G (with the gate L withdrawn to permit it) passes directly onto the top of said die.

The raceway G is preferably kept full of washers from topto bottom, thefbottom washer resting normally against: the smooth inner edge ot the gate L.

K isa table which by meansof the screw 7c is held on the top of the sleeve K on alevel with the top surface thereof. This table supports the material on which the buttons are to be mounted.

The plunger H and thev movable die H attached thereto have their central axis inline with that of the stationary die I. y g Starting with the raceways both fullwith la washer on top of the4 movable dielI-I, and lwith the material on which the buttons are lto be mounted rest-ing in proper position on the tablefKQthey operation of the machine is fas followsz-Therod P is pushed upward (as by a` down strokeof the foot on the treadle) thus'movingthe plunger and with it theqdie H upwardin the casing A3, carrying the washer S up against theunder surface of the Amaterial as it rests on the table K and then,

continuing upward, lifts the material-with it,

and pushes it against the downwardly pro.-

;jecting eyelet R of the button under the die drawn allowing the lowermost washer` in the raceway G to fall into the opening left by the gate, said washer resting against the plunger. When theplunger descends `and the cam arm H2 passes out of contact with the roller L', the beveled portion Z2 of the gate L ispressedby the spring Z against the washer S which has dropped in the path of the gate, so thatwhen the top of the die H has passed beneath the IOO opening occupied by the washer, the said gate springs back` inplace and moves the said lower washer into the plunger casing upon the top of the dieH in to the position shown in Fig. 1.

Meantime, the operator by pulling.

the material has removed the button last set from under the die I past the holding spring F2 and another button top or head drops into place against said spring.

It is my purpose to have the machine perfectly adjustable for different sized button heads and washers. The hoppers C and D may be readily removed and replaced by others containing different sizes of button parts, the openings c and d being of course of proper size to feed the particular part into the raceway.

The dies H and I may be readily removed and replaced by others of sizes corresponding to the button parts, and the sleeve K is also removable, it being of course necessary to have the sleeve in each case correspond in size of central opening with the size of the die H.

It will be noticed that by the peculiar construction and arrangement of the parts, the washers are fed one by one from the raceway onto the movable die at its lowermost position, the washer on the top of the die being` then moved upward, through the passage way which it approximately tits, almost to the point of clinching, thus securing great accuracy in bringing the two parts of the button together.

l. In a button setting machine the combination of a stationary die,means for holding a button head with its rivet centrally beneath said die, a guiding passageway, a movable die, fitting said passageway and having a vertical reciprocating motion therein, and a washerguiding raceway communicating with said passageway just above the top of said movable die, when at its lowest position, and adapted to deliver awasher on the top of said movable die, substantially as described.

In a button setting machine the combination of a stationary die and raceway F a guiding passageway, a plunger, a movable die mounted on said plunger fitting said passageway and having a vertical reciprocating n10-` tion therein, an inclined washer-guiding raceway having communication with said passageway just above the top of said movable die, when at its lowest position, and a reciprocating gate F horizontally movable across the path of said raceway between it and the passageway, said gate being beveled at its forward end, substantially as and for the purposes described.

5. In a button setting machine the combination of a stationary die and raceway F the plunger H, sleeve K, die H', inclined raceway G, spring actuated gate L, having the beveled portion Z2 and provided with the roller L', and the cam-arm H2 secured to said plunger and engaging with said roller, substantially as and for the purposes described.

6. In a button setting machine the combination of a stationary die, a vertically reciprocating die, a plunger operating the movable die, hoppers for the button heads and rivets actuated by said plunger, a twisted raceway leading from the buttonhead hopper to the stationary die, an inclined raceway passing from the washer hopper to said movable die, and a plunger-operated washer-separating gate interposed between said raceway and said movable die, whereby at each stroke of the plunger a washer is moved from the raceway and deposited on the movable die at its lowest position, substantially as described.

In witness whereof I have hereunto set my hand.
