BUTTON-MAKING MACHINE.
Application filed April 19, 1924; Serial No. 707,603.
To all whom it may concern:
Be it known that we, CHARLEs H. MILLI- KEN and 'AUGUs'rUs HEGK, citizens of the United States, and residents of Newton, Commonwealth of Massachusetts, have invented an Improvementin Button-Making Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views. a I This invention relates to machines for making buttons of a type embodying an ornamental pearl or'like head with a headed wire shank fitted therethroughand bent into an eye or loop. A principal object'ofthe invention is to provide a machine that is entirely automatic in operation for bending the wire shanks of these buttons to form the eyes thereof, the machine being adapted to receive the buttonheads with the headed wire shanks fitted therein, and to complete the making of the button by the necessary forming of the projecting wire'shank into the completed eye, which is pressed inward into proximity to the inner side of the head. A further objectis to provide a machine of this kind of relatively few parts and that is capable of rapid. operation, and with a capability of handling a substantialirange of button sizes. The foregoing and other objects and advantages of the invention will more fully appear from the following de tailed description taken in connection with the accompanying drawings. and the distinctive features of novelty will be pointed out in the appended claims.
Referring to the drawings:

10 indicates the framework and base of the machine, upon an upright portion of which an inclined chute 11 is mounted, to the upper end of which is applied a suitable hopper (not shown) for delivering the button heads with the headed shank wires 'fitted therein to slide down the inclined chute 11. The machine framework is provided with a lateral, extension 10 presenting an inclined face 1O extending approximately at right angles to the direction of the chute, and upon this face a bar 12 is mounted for sliding movement. The extension lO is provided with a projection bearing a bracket 13 equipped with an adjusting screw 14 adapted to limit the outward movement of bar 12, and to determine its location so as to be in position to receive a button of any given size from the chutc as presently de'.
scribed. The outer portion of the bar 12 is equipped with a lug 12* in which is fitted an adjusting screw 15 adapted to engage the base extension 10f to limit the inward movement of the bar 12 and locate it properly for deliveringthe button to the operative station as will be explained. The bar 12.has
adjustably fixed thereto, a head 16 hearing a recess 17 adapted to receive the projecting wire shank of the button from the chute withthe head of the button resting on the top of the head 16 as thebutton slides on to said head by gravity from the chute.
The head 16 is equipped with provision for small lateral adjustment upon the bar 12, for this purpose having a tail portion thereof provided with a transverse rib 18 which fits into a transverse slot in the top of the bar 12 with a clamp screw 19" set through a short transverse slot in the shank of the head 16 and threaded into the bar 12, the purpose of this, adjustment being to set the parts accurately for different sizes of buttons. The bar 12 has a short lateral projection 12 at itsinner end which bears a pointed beak or finger 20'extendin past the slot or recess 17 The purpose of this is to insure that the foremost button in the chute will be caught and deposited upon the head 16 with its shank extending into the recess 17, while holding back the rest of the line of buttons in the chute as the bar 12 starts in its movement to bear the button held thereon to the operative station. For reciprocating the bar 12 to thus transfer the successive buttons from the chute to the operative station, its under side is formed with a rack 21 which is engaged by a gear segment 22 pivoted to the housing at 23, and having a depending tail portion pivotally connected at 24 with a composite or twopart bar 25. The bar 25 is composed of two parts having a small relative endwise telescopic movement as permitted by a pin and slot connection 26 therebetween, and with a stout coil spring 27 housed in one of said bar portions and reacting against the other one thereof to hold them normally at their outer limit of extension. The inner end of the bar 25 has pivotally connected thereto at 28, a lever 29 which is fulcrumed at an intermediate point to the framework as indicated at 30, and has its upper end portion equipped with a roller 31. This roller engages a lateral cam 32 fixed on the shaft 33, which is journalled in the top of the framework and constitutes the prime drive shaft of the machine, being shown as equipped with a suitable operating pulley 34, and stop motion device indicated generally at 35. This stop motion device constituting no part of the present invention need not be here explained in detail. For causing the pulley 31 to constantly engage the cam 32 and thus cause the bar 12 to be retracted outward, the lever 29 is equipped with a tension coil spring 36, the other end of which is anchored to the framework. A plate 37 is adjustably fixed to the base a small distance inward from the chute 11 with its inner end portion reduced in thickness as indicated at 37 so as to have adegree of resiliency, this inner end portion being unsupported by the base and extending inward to the locality of movement of the bar 12. This inner plate portion 37 a has its extremity notched as indicated at 37 to permit the button shank wire to slide into such notch with the head of the button resting on the.
on the plunger 58. To insure a positive retraction of the die 56, in case the spring 64 should fail to act properly, and toprevent interferencewith the upward IIIOVGIDGlli/O'f the forming die 41, a bent lever 65 is pivoted on the pivot 61 of the framework with a lower arm engaging a pin 66 borne by the plunger 58, while an upper obliquely extending portion 65 of this lever is engaged by astud' 67 borne on the side of the cam 63, this stud engaging the arm '65 after the die 56 has been moved inward and performed its function, to positively retract said die. The described movement of the die '56- to thus preliminarily bend the button shank operates to press said shank bodily laterally to a -small extent, and so that its bent lower end is pressed over the forming dietl and into a concave formation 41 in the top thereof as indicated in Figure 8.
' To insure that the die 41 will be located at the proper elevation so that this willoccur for different lengths of button shanks, the lever45 is equipped with an adjustable stop screw 68 which engages an abutment 69 provided therefor in the base, the adjustment of this screw serving to locate the die ll with precision at its lower limit of movement and when the described operation of the die56 takes place. The cams 53, 63 are so designed andproportioned that as soon as the described preliminary bend has been made in the shank wire, and the die 56 withdrawn, the die 41 is pressed upward by the action of the cam 53 to complete the bending and curling of the shank into a completed button eye as indicated at S in Figures 9 and 13. During the described bending and forming operations upon the shank wire the button is held firmly and immovably pressed upon the plate 37 by the engagement therewith of the lower end of a plunger 70, which is fitted for vertical sliding movement in a bearing 71 of the framework. This plunger has a compression coil spring 72 reacting thereon to press the same upward, this spring being housed within the bearing 71 and reacting against a shoulder of said plunger. The plunger is engaged to press and hold the same downward periodically, during the described bending operations by the engagement with the upper end thereof of an adjusting screw 73 borne by one arm of a bell crank lever 74., which is fulcrumed to the frame at 75 and has the other upwardly extending arm 74 thereof equipped with a roller 76, which engages a peripheral cam 77 on the prime drive shaft 33. It will be understood that the adjustment of the screw 73 is adapted to take care of different thicknesses of button heads so that the movement imparted by the cam 77 will be suificient to press the plunger 70 firmly upon the head of buttons of any particular dimension, while the plate 83 borne by the plunger 70.
