MACHINE FOR THREADING BUTTON-FASTENERS INTO THE EYES F BUTTONS.

SPECIFICATION forming part of Letters Patent No. 491,103, dated February '7, 1893.

Application filed March 21. 1892.

T0 aZZ whom it may concern:

Be it known that I, ALBERT W. HAM, of the village of Lansingburg, county of-Rensselaer, State of New York, have invented new and useful Improvements in Machines forThreading Button-Fasteners into the Eyes of Buttons, of which the following is a specification.

My invention relates to improvements upon that class of machines that are used to thread button fasteners into the eyes of buttons and to place the buttons and fasteners so connected within a slotted tube, that is when filled with buttons and fasteners so connected, attached to a button setting machine; and which class of machines are termed tubeloaders.

It is theobject and purpose of my invention to better adapt this class of machines to the uses for which they are designed.

. button receiving tube is located facing the view. Fig. 2, is an end view with that end of the machine in which the button-fastener hopper is located facing the view. Fig. 3, is a section taken on the line 00', 0c, of Fig. 1.

' Fig. 4:, is a section taken on the line x m of Fig. 1.

Fig. 1. Fig. 5, is a transverse section taken through the button hopper with the button striker shown as forced away from the button passage-way made in the hopper side. Fig. 6, illustrates the same parts that are shown in Fig. 5, but showing the button striker as forced within the button passage in the side of the button hopper. Fig. 7, is a transverse section taken on the line 00 m of Fig. 8, is a side elevation of the slot in which the buttons are held while fasteners are being threaded into the eyes thereof with all those parts in front of said slot removed. Fig 9, is a perspective of the button striker illustrated as removed from the machine. Fig. 10, shows asdetached from the machine a T- form leaf spring which when in position ,holdsthe descending button in position until Serial No. 425.691. (No model.)

The several parts of the mechanism thus 7 described illustrated are designated by letter reference and the function of the'parts is described as follows.

The letter B,designates the base or support on which the machine rests, and F, its

frame with which the mechanism connects.

This frame consists of ,the studs f f projected upwardly from the base,a curved upcast arm f and lateral frame extensions f f The letter H, designates the button-hopper which is positioned on an incline with one side lower than the other, and is connected to the upcast arms f and f by means of an 0% set arm'O, projected from the latter. hopper is made with a revolving brush-ring R, arranged at its top, and this ring has radially arranged and interiorly placed arms that connect it centrally to a shaft 71?, that is also inclined enough from a perpendicular to be at right angles to the hopper bottom h This shaft journals in a sleeve form hearing if, that is downwardly projected through the hopper bottom.

This

The letter W, designates a button receiving slot that is circularly arranged in the hopper bottom a short distance from its outer edge. This slot has one closed end h", and at its other end it curves outwardly so as to pass through an opening 0 made in .the button hopper side and, thereat 'to connect with a slot made in the plate h", from and through The letter K, designates a crank on the outer end of the shaft S, for operating the latter. When the ring R, thus constructed and connected is operated to, turn, the buttons within the hopper are moved around by the brushes so that some of them will have their shanks within the slot h andsuch as take this position will be moved around through and out of the slot in the hopper bottom so as to pass out of the side of the latter into a connected slot from whence they pass to where the staples are threaded into the eyes thereof.

The letter T, designates a button striker which connects with the circular exterior side of the button hopper by means of a leaf-' t, forced inwardly so as to enter the opening O ,'and to strike the button thereat within The uses of the striker thus constructed and ar the slot h and knock it out of the slot.

ranged to operate is to prevent buttons that are crowded into the slot by'some one of them being improperly positioned therein from remaining there, so that their passage is obstructed, and thus clearing away the button at-the point where the slot in the hopper bottom curves to pass from the hopper at eachrevolution of the ring R, to keep the slotfree; there always being enough buttons in position within the slot so that the removal of one of them at each revolution of the ring does not interfere with the proper working of the machine and avoids a difficulty com-;

mon to machines of this kind.

The letter M designates the staple or fas-f tener hopper which is attached to the lateral extension of the frame-part f". This staple or fastener hopper is elliptical in transverse section, and is cut away on one side and front as indicated at m Figs. 1 and 2.

The letter m designates a blade having a downwardly and frontwardly inclined upper edge m and this blade is connected at its lower end where below the hopper with a plunger P, and this blade is made with a slide-way in the hopper sides and extending below the hopper as indicated at and this plunger is operated to be vertically reciprocated so as to move the blade up and down within the hopper by means of a connecting rod m which is pivoted. at its lower end to the said plunger, and at its upper end connects with the wheel m by means of a crankpin on as shown at Fig. 4:. This wheel m is arranged on and secured to the shaft S, and receives power therefrom, and by which the plunger P, and connected blade m are vertically reciprocated within the hopper M.

The letter on, designates a tumbler which is projected up through the hopper bottom so 7 as to straddle and be upon both sides of the blade m one of its sides being shown at Fig. 2, and the other at Fig. 4-, its construction upon each side of the blade being the same; and it is provided with a slide-way in the hopper bottom. The function of this tumbler is to change the position of the fasteners at each vertical reciprocation of the blade and tumbler and thus facilitate the capacity of the blade to catch the fasteners, which if the blade alone were used would tend to position themselves with their bend ends downward in which position they would not be so readily caught by the blade.

The connecting-rod m is made in two parts and arranged to operate elastically in its engagement with the plunger P, by the following construction.

The letter C designates a chamber-formed within the rod proper said chamber containnecting rod proper at its lower end pivotally connecting with the plunger P.

The style of button fasteners to which my improvements herein shown are adapted to use have a U-form and as the blade m is reciprocated within the hopper M, the fasteners are fished out by the blade so as to straddle the inclined upper edge of the latter, and to slide down on to the inclined top edge of the vertically placed plate N, which is in vertical alignment with the blade, and having its top edge with the same inclination as the latter; so that fasteners or staples will in their descent from one pass on to the inclined top edge of the other. The top edge of the plate N, is indicated at W. The letter a designates a detaining-plate that'at'n, is pivoted to a plate on the edge of the hopper M, where cut away at m and the letter a designates a leaf-spring which at its upper end a, is attached to the same plate as that to which the detaining plate is pivoted; with the lower free end of said spring resting on the top edge of the detaining plate. When the latter is forced down by gravity and the spring 7?, the lower edge of said plate is in parallel alignment with the top edge of the plate N, where it detains all the fasteners thereon excepting the bottom one which is free to descend shank-end foremost into and through the passage-way n", as shown at Fig. 3. This detaining plate a is made with a cam surface 12, on its edge the function of which will bedescribed in connection with the operation of the threading finger.

The letter D, designates an arm that is made with a threading finger-part d adapted to be moved back and forth in the passage IIO letter d designates a crank-arm on the shaft way m and this arm is made with a cam (1 on its rear edge, and at its lower end isconnected so as tobe moved by the shaft S so that the curved threading finger will pass into and from out the curved passage-way 91.

when the threading finger is moved downwardly the cam (1 on the arm D, engages with the cam W, on the outer edge of the detaining-plate 02 so as to move the latter away from its staple holding engagement with the staples astride of the plate N, and allows the staples to slide down on the latter to stop against the ed e of the threading finger when the latter has descended into the passage-way M; and when the threading finger has completed the work of threading astaple into the eye of a button and rises from out of the passage way n it releases the detaining-plate which by gravity and its spring is forced down on top of the staples astride of the plate N; to

hold all but the one at the lower end of the plate, which is free to descend into the passage-way n prongs downward to be forced into the eye of a button at a succeeding descent of the threading finger.

The arm D,,and its finger 01 are arranged on the'shaft S to be moved by the latter intermittently,and reciprocatingly by a connection made with the wheel W", on the shaft S, and by the following mechanism. The

S with the latter having its bearings at b and this crank-arm pivotally connects with a pitman d which at its inner end is pivoted at 61 to a cam-pin arm (1 which latter at its upper end 01 is pivoted to an ofiset d made from the frame and the letter 01, designates a cam-pin on the lower end of the arm d, which pin is arranged to run in a cam groove d made in that face of the wheel m which is opposite to that on which the connecting rod m of the plunger P connects to said wheel, as shown at Fig. 4. As thus connected with the wheel m, on the shaft S, at each revolution of the latter the threading finger is operated to descend into the fastener pas sage n, to thread a fastener into the eye of a button and the arm D, is operated to so move the detaining plate as to allowa single staple to descend into the staple passage-way as before described. The buttons after being forced from out of the buttonhopper enter a continuation of the same slot connecting with the one in the bottom of the latter which continuation is produced in the plate 727,

and from which they'pass into the slot 9 made in the chute L. This latter is formed by the slotted plate if, and the cover-plate p, as shown at Figs. 4t, 5, and 6. curves outwardly and downwardly and with its button slot curves laterally to connect by a bend therein with a horizontal slot-part The buttons pass downwardly in the slot-part g by gravity and are kept from falling out 6 5- horizontal slot-part of the chute L,its furby the cover plate 10 7 Soon as the button in advance has passed into the entrance of the This chute L, I

I and held in a position opposite to the bot-f1 tom of the staple passage-way 07, and where the threading finger (1 will guide 'a fastener so as to have one of its prongs enter the eye in the button shank. While the fastener or staple is being threaded into the button eye the plunger, P rests momentarily, and then moves the button and inthreaded fastener through the horizontal slot-party", beyond the staple or fastener passage of, and from under the action of the spring I so as to pre" vent two fasteners from being threaded into the same button eye should another button not come into position at the bottom ofthe fastener passage, before the threading finger again descends. After being moved out in the horizontal part of the slot 9*, beyond the bottom of the fastener passage by the vplunger, the buttons crowd one anotheron until they reach the bend connecting the horizontal slot part with the slot part 9 when they enter the slot in the-button tube V, where they are retained-by the fasteners, from falling out the slot. The button plunger P is made with a slide-way U, attached to the side of the frame, and when moved therein toward the bottom of the fastener-passageway n it passes in front of the slot 9 so as to engage with the side of each button therein to move it. This plunger is operated by a lever Z that at its outer endl is pivoted t'o the frame of the machine as shown in a top view at Fig. 7, and at its other end this lever is pivotally connected with the'plunger P The letters 1, and Z designate cam-pins having friction.

passing between the cam-pins. The blade m is made to move elastically by means of a spring in the rod or pitman connecting it with the wheel that actuates it for the following purposes. When the blade has reached the limit of its upper movement it is desirable that it should pause or rest in its movement before descending a sufficient length of time to have the fasteners slide from its inclined edge onto the edge of the plate Nand by having also a ring made with brushes on its under face actuated to be rotated in thehopper so as to position buttons with their shanks. in the slot of the hopper bottom and tomove' them so placed into a slotoutsidezof the but-l ton hoppersis .an old and well known construction and I make no claim to .the'samef apart from the button strikerthat I combine;
