BUTTON-ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 432,37 5, dated July 15, 1890. Application filed March 19, 1890. Serial No. 344,544- (No model.)

To all whom it may concern.-

Be it known that we, CLYDE J. COLEMAN and CLARENCE W. COLEMAN, of Chicago, in the county of Cook and State of Illinois, have jointly invented certain new and useful Improvements in Button-Attaching Machines, of which the following is a specification.

This invention relates to the type of buttonattachment machines described in Clyde J.

X0 Colemans application for Letters Patent, Se-

rial No. 319,608, filed August 3, 1889, and in which the buttons from afeeding-hopper are fed down a feed-chute by gravityinto proper position with relation to the fastener, forming, and clinching dies to receive a section of wire that, in the operation of the machine, is first threaded through the eye or shank of the button, then severed, and bent into the required form to constitute the fastener or Sta-- :0 ple that clinches through the shoe-upper to attach the button thereto; and the present improvements have for their object, first, to provide a simple, durable, and effective in echanism for effecting the feed of the buttons 2 5 from the button-hopper into the feed-chute, and insuring such a position of the buttons within the chute that their shanks will project through the longitudinal slot in the wall of the chute, so as to pass down into the path of and be threaded upon the fastener-forming wire in the operation of the machine; second, to provide means at the lower end of the but ton-chute for effectively holding the lowermost button, so that'its shank will project be- 5 tween the fastener-forming dies and in the path of the fastener-forming wire, so as to be threaded thereon, the construction being such that the passage downward of the button out from the chute to the clinching-anvil will an- 0 tomaticallyopen the holding mechanism at the lower end of the chute to receive and hold the next button in position to be threaded upon the fastener-forming wire in the continned operation of the machine; third, to af- 5 ford a simple and effective automatically-op crating feed mechanism for feeding the wire at proper intervals through the button-eye and across the severing-throat of the machine to be cut off at each operation of the machine into a section of the required length to form the staple or fastener; fourth, to supply a simple and durable construction of parts for releasing the pivoted member of the fastenerforining dies after the fastener has been crimped thereon to form the central loop or 5 5 eye for the shank or eye of the button; fifth, to-providea simple and effective locking and unlocking mechanism between the dual parts of the reciprocating member of the wire severing and fastening forming dies, which automatically locks the parts together during the severance of the section of wire and the formation of the same into a fastener and unlock the parts after such formation is effected and before the clinching orsetting operation takes place to attach the button to the shoe-upper. W'e attain such obj ect by the construction and arrangement of parts illustrated in the accent panying drawings, in wliich Figure 1 is a side elevation, partly sectionized, of our improved machine, the moving parts being shown in the upper position ready to descend; Fig. 2, a detail side elevation, partly sectionized,of the upper part of the machine,illustrating the button-feedin g mech- 7 5 anism in the downward movement of the machine part-s; Fig. 3, a similar view of the same during the upward movement of the machine parts; Fig. 4, an enlarged detail front elevation, partly sectionized, of the machine; Fig. 8c 5, an enlarged detail longitudinal section of the same; Fig. 6, an enlarged detail horizontal section through the wire-severing throat of the machine; Fig. '7, an enlarged detail section of the lower end of the button-chute; Figs. 8, 9, and 10 are detail sectional diagrams illustrating the different steps and position of parts in the formation and attachment of the wire-fasteners, and Fig. 1]. an enlarged detail plan of the stripping-plates 0 in the button hopper "or receptacle and its connections.

Similar letters and numerals of refere indicate like parts in the several views.

As represented in the drawings, the general 5 arrangement of the wire cutting and fornlin dies for severin a section of wire, the thr d: ing of the same through the eye or sl f the button, the after formation of the wire into a fastener, and its subsequent clinching or setting in the shoe-upper, as well as the general arrangement of the mechanism for imparting motion to the part i Substantially the same as that shown in application for Letters Patent, Serial No. 319,668, filed Au gust 3, 1889, by Clyde J. Coleman.

Referring to the drawings, .X represents the supportingstandard of the machine, through the center of which passes and is properly guided the verticallyanoving stem Y, the lower end of which is suitably connected to the foot-treadle or to any other suitable driving mechanism, so as to receive a reciprocating movement therefrom, while its upper end carries an overhanging cross-head I, to the top of which is attached in a pivotal manner the magnet 2, that by its magnetic attraction lifts the buttons by their metallic eyes or shanks from the stationary button receptacle or hopper 3 and deposits the same on top of the stripping-platcs 4, with the buttonshanks lying between said plates. The top edges of these plates are inclined toward the forward end of the hopper, so as to shed the buttons by gravity into the button-receiving chute 7 of the machine, and are formed with lateral horizontal flanges 5, that widen toward their rear ends, as shown in Fig. 11, so as to afford a support to the body of the button while the magnet l is drawing the button-stem into the space between such plates.

6 is a central guard-finger projecting inwardly above the mouth of the chute 7, the purpose of which is to divert back into the hopper any button that may roll along the top of the plate without its shank being in proper position in the space between the plates. The distance between these stri 'lping-plates is just sullicieut to receive the button-shank, so that the body of the button will ride upon the top of the said plate and be guided in its descent into the luitton-ehute 7 by means of its shank or eye, the longitudinal slot 8 in the rear wall of the button-chute 7 being a continuation of the narrow space between the plates Ii. With this improved construction the proper position of the button in the but ton-chute is absolutely insuredto wit, with their shanks or eyes projecting through the longitudinal slot 8 in the rear wall of said chute.

The movement of the magnet 2is of a fourmotion natnre-to wit, upward in a rear vertical plane back of the stripping-plates 4, as illustrated in Fig. 3, then forward in an upward and substantially horizontal plane, as illustrated in Fig. 1, then downwardly in a forward vertical plane between the strippingplates 4, as illustrated in Fig. 2, and then back wardl y in a horizontal plane to the point of starting, as above set forth. This compound movement is imparted to the magnet during its ascent: and descent with the crosshead 1 by means of a sleeve 9, sliding with some friction on a stationary guide-stem 10 and having a horizontally-extending arm 11, that has pivotal connection at its forward end with the hub of the magnet 2 at one side, and to the rear of the pivotal connection of the magnet to the cross-head, as clearly illustrated in Figs. 1, 2, and The action of this improved construction is as follows: As the cross-head l and magnet 2 commence to descend, the friction of the sleeve 9 upon its guide-rod 1O retards or checks its movement along with the magnet, so as to tilt or draw the "upper end of the magnet forward in a horizontal plane, and in like manner, as the cross-head and magnet commence to ascend, the friction of said sleeve upon its guide-rod will check or retard the upward movement of said sleeve along with the magnet and crosshead, so as to tilt or draw the upper end of the magnet backward in a horizontal plane. 12 is a temper-screw on the sleeve 9 for adjusting and regulating the friction between the same and its guide-stem.

The magnet 2 is preferably of a horseshoe shape, as shown. A bar or other suitablyshaped magnet may, however, be used instead without departing from the spirit of our present invention.

The cross-head 1, in addition to carrying the button-feeding magnet 2, also carries at its forward end the vertically-moving twopart member 13 1+ of the wire severing and forming dies. The companion member of such dies consists of an angular lever pivoted in the main standard X, with its anvil portion 15 projecting into the wire-severing throat 16, formed in the stationary bench 17 upon the standard X, as clearly indicated in Figs. 1, '-l, and 5. The general construction of these partsis in the main substantially the same as the mechanism set forth in the aforesaid applieation of Clyde J. Coleman, Serial No. 319,668.

Such mechanism for severing a scctionof wire, forming it into a staple or fastener, and clinching itin the shoe-upper consists, briefly, as follows: The wire-severing throat 16 in the bench 17, across which the wire is fed, a descending plunger 14 for severing a section of the same and bending it into a staple form upon the pivoted die oranvil 15, amain plunger 13 for crimping the middle of the staple to form a receiving-loop for the button-shank, and a stationary clinching-anvil 19 on the standard X for clinching or setting the ends of the fastener in the shoe-upper. The plunger 14: is adapted to have a limited vertical movement on the plunger 13, a spring 20 being employed to hold the two in a separated condition, and a locking-dog 21 for locking the parts in such separated condition. The construction being such that the two parts will be fixedly held apart while the plunger 14 is severing the wire, forming the same into a staple, and carrying the same down onto the stationary clinching-anvil 19, at which point, and just before the clinching operation commences, by the further descent of the plungers 13 and 14, the parts are released by the rearwardly-projecting end of the dog 2 coming in contact with the rear edge 22 of a slot in the guide-bracket 18 of the plnngers 13 and 14. The main plunger 13 is then free to further descend and complete the clinching or setting of the fastener in the shoe-upper as it rests upon the stationary anvil 19.

The dog 21 in the present invention is pivoted to the upper plunger 13, with its pendent portion 23 engaging the top edge of the plunger let, while its upper end projects back in an inclined direction, so that as it passesing against the side of the vertically-moving stem' Y of the machine, and it is released so as to move out of the way when the staple has been formed and crimped by the recess 27 in the stem Y, into which the end of the arm 26 swings when the proper position is reached. 28 is a spring for returning said pivoted anvil to its proper horizontal position in the severing-throat 16.

The button-chute 7 extends down the front side of the throat 16, so that the buttonshanks will project into said throat, so as to be in proper position to be threadedonto the section of fastener-wire, and in order to effectively and positively hold the lowermost button in proper position while being threaded onto the wire the front of the chute, near the lower end, is cut away and provided with a spring-holder 29, the lower end of which is formed into a cup-shaped cavity 30, of a form approximating the body or head of the button and adapted to receive the same and firmly clamp it against the rear wall of the chute, as shown in Fig. 5, while the end of the fastener-wire is being passed through the eye or shank. The lower end of the spring-holder 29 is formed with a straight downwardly-extending skirt or extension 31, that bears against the button as it is drawn downward out of the button-chute, so as to keep the spring button-holder open to receive thenext adjacent button into its holding-cavity 30.

32 is a spring-fingerimmediately below the holding-cavity 30, that rides over the outpassing button and springs in underneath the next button above to prevent it dropping out until the spring-holder29 moves back to clasp such button in its holding-cavity 30.

In the present invention the fastener-wire is fed from a suitable reel 33 into the severing-throat 16 by the following automaticallyoperating mechanismi 31L is a reciprocating feed-head sliding upon a stationary guide stem 35 and having a spring-dog 36, that engages the side of the fastener-wire as it lies in a horizontal troughshaped passage or way in the feed-head 34, motion being communicated to the feed-head by means of a lever 37, pivoted to the bracket 18, its lower end being connectedby an elongated slot 38 and stud 39 to the feed-hcad, while its upper end projects between the upper and'lower studs 40 41 on the plunger 13, to be operated by the same as it vertically reciprocates. In this construction the parts will be so proportioned that the feeding-head 34 at each forward stroke will feed the exact length of wire required to form the fastener.

42 is a spring-dog within the bench 17 for engaging the wire and preventing a retrograde movement of the same.

It is preferable to form the abutment for the end of the wire in the severing-throat 16 of an adjustable nature, so as to secure a central position of the fastener, and this is accomplished by providing the bench with an adjustable abutment-plug 43, held in place by a set-screw 44 or other like means.

Having thus fully described our said invention, what We claim as new, and desire to secure by Letters Patent, is- 1 1. In a button-feeding mechanism for button-attaching machines, the combination of the reciprocating cross-head 1 of the buttonattaching mechanism, a stationary button hopper or receptacle, a button-receiving chute connected near the top of the hopper, a reciprocating magnet attached to and moving with the cross-head 1, and a pair of stripping-plates located at the sides of the magnet and forming an extension of the button-chute, substantially as set forth.
