MACHINE FOR SETTING FASTENERS.

Original application filed June 15, 1918, Serial No. 240,202.

Divided and this application filed June To all whom it may concern:

Be it known that I, SYLVESTER L. GooKIN, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain improvements in Machines for Setting Fasteners, of which the following description, in connection with the accompanying draw ings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for insorting fasteners and more especially to those for setting compound fasteners. In United States Letters Patent 1,371,364 granted March 15, 1921 upon my application, I have shown a machine for setting two-part fasteners, said patent disclosing a hopper in which both parts of the fasteners may be intermingled and from which they are segregated and fed so that exclusively those of one shape or size will be fed to one side of the setting locality while exclusively those of another shape or size will be fed to the other side of the locality and there assembled in cooperative relation and clenched. So far as the former patent is concerned this present application is a division.

Although the type of fastener illustrated in my former patent and also in this present application is said to comprise telescopic eyelets the primary object of this phase of the invention is to segregate and feed the complemental parts of compound fasteners differing from each other in any physical respect that will permit such control. I-leretofore machines for feeding and setting compound fasteners have been provided with separate hoppers for the differ- Y ent kinds of fastener parts, and while the provision of a plurality of hoppers has encumbered the machines and has increased the problems of organization and the cost of manufacture, it has been considered necessary in every case when compound fasteners are used. This invention, therefore, overcomes the aforesaid diificulties of organiza tion and reduces the cost of manufacture by providing a single hopper in which assorted fastener parts may be. initially intermingled in a mass, and by which they will be automatically segregated and-fed according to kind.

Patent No. 1,371,364, dated March 15, 1921 30, 1920. Serial No. 392,910.

A. feature of the invention consists in means constructed and arranged to segregate and feed dissimilar fastener parts from a mass so that only those of one kind will pass from the hopper into each raceway, the raceways being formed and arranged to. conduct the segregated fastener parts along. different courses to thesetting mechanism by which they are assembled and clenched in cooperative relation. According to a simple and convenient embodiment of the invention such segregation may be effected by providing the hopper with outlet ports of different proportions corresponding to those of the fastener parts, each outlet port being of such shape and size as to permit the escape of fastener parts of one kind and to prevent the escape of all other fastener parts.

A construction embodying the aforesaid features is illustrated by the accompanying drawings and is hereinafter described and claimed.

In the drawings,

Fig. l is a perspective view including a sin le hopper and two raceways constructed and organized in accordance with this invention, together with fragments of suitable setting mechanism to which the fastener parts are supplied;

Fig. 2 is a section in a vertical plane through the elements at the setting locality, showing two cooperative setting tools inthe act of taking the two complemental parts of a two-part fastener from their respective raceways Fig. 3 is a sectional view including a frag ment of the hopper in which outlet ports for one kind of fastener part are provided; and

Fig. 4 is a view similar to Fig. 3 showin another fragment of the hopper in whicfi outlet ports for the other kind of fastener are provided.

in describing the invention with regard to twopart fasteners, both kinds of fastener parts are intermingled in massed formation in a hopper 10 which, in the illustrated machine, has an annular wall 11 and is arranged so that its axis is inclined. Two race ways indicated at 12 and 13 are rigidly connected to the hopper so that they, together with the hopper, may be oscillated to shift their delivery ends. to and from by Fig. 3.

registration with cooperative setting tools 14 and 15. According to the construction shown the raceways are arranged to receive fastener parts from opposite sides of the hopper, the annular wall 11 being provided with outlet ports 16 at one side and with outlet ports 17 at the opposite side.

' The complemental fastener parts shown by the drawings are eyelets of telescopic proportions, those of smaller diameter being indicated at 18 and those of larger diameter being indicated at 19. It is to be understood, however, thatthe invention is not limited to any particular type of compound fastener. The assorted fastener parts massed in the hopper are supported by the bottom wall 20 of the latter and may be moved about in the hopper by any suitable or preferred means such as a rotary or oscillatory brush, a portion of which is indicated at 21 in Fig. 1.

Theinvention utilizes physically different characteristics of the fastener parts to control segregation, and sinceeyelets of telescopic proportions are represented for the purpose of disclosing the principles of the invention the particular physical characteristics of-such eyelets will be described. The eyelets 18, for example, have relatively small diameter and their barrel portions are relatively long whereas the eyelets 19 have relatively large diameter and their barrel portions are relatively short. Accordingly the outlet ports 16 for the eyelets 18 are relatively narrow and deep, while the ports 17 for the eyelets 19 are relatively wide and less deep. The proportions are such that the eyelets 18, when standing on their flanged ends as shown by Fig. 1, may pass freely through the ports 16 and thus enter the upper end of the raceway 12. On the other hand, the eyelets 19 can not escape through the ports 16 because the width of the latter is less than the diameter of the barrel portions. These conditions are clearly shown Again, the eyelets 19 standing on their flanged ends may pass freely through the ports 17 and thus enter the raceway 13 but the eyelets 18 can not escape through these ports because their barrel portions are too long. These conditions are clearly shown by Fig. 4. It sometimes happens that two complemental fastener parts Wlll become nested as represented at the right of Fig. 1, and when this occurs they are prevented from escaping from the hopper because the ports 16 are too narrow for the outer eyelet while the ports 11? are too shallow for the inner eyelet. Nested eyelets are therefore retained in. the hopper until they become separated by the brush 21 or by tumbling. Any desired number ofoutlet ports may be provided, and if the construction includes more than one of each size they may be grouped closely in serial relation so that if-the lower edge of the annular wall 11 is cut away as indicated at 22 to provide a continuous space for the flanges resting on the bottom wall 20 it will not be excessively weakened. It is obvious that the eyelets can not, escape in any case unless their flanged ends are resting on the bottom wall. I

Although the work-punching devices and the setting tools herein illustrated are the same as those shown in the aforesaid patent they may be described briefly. A tubular punching tool is indicated at and a solid punch-block for cooperating therewith is indicated at 24. As shown by Figs. 1 and 2 these punching devices are separated to clear an article of work comprising layers 25 and 26. The work rests on a support 27 and its upper edge is in contact with an edge-gage 28. The punching tools are brought together at one side of the support 27 to punch a hole in the work without displacing the latter from the support 27. WVhen the punching operation has been executedthe tools 23 and 24 are both retracted from the work and are then moved laterally to the positions shown by l ig. 2, the setting tools 14 and 15 being thereby moved into registration with the punched hole.

The setting tools are then moved toward each other, and during the first stages of such movement they enter the'lea ding eyelets at the delivery ends of the raceways re spectively as shown by Fig. 2. At this stage of the cycle of operations the delivery ends of the raceways move laterally so as to clear the setting tools, and the latter continue to move toward each other, first to assemble the eyelets in telescopic relation in the work and then to clench one or both eyelets.

No attempt has been made to represent herein the mechanism by which the setting toolsare moved laterally to feed the work, and it will be sufficientfor present purposes to state that the heads 31 and 32 in which the punching tools and setting tools are mounted are reciprocated in such manner as to impart feeding motion to the work while the setting tools are in clenching position.

Referring to Fig. 1 it will be observed that the raceway 12 is so formed as to invert the eyelets that pass through it but that the raceway 13 does not embody such feature. Consequently, although both kinds of eyelets stand-on their flanged ends when passing through the outlet ports of the hopper, they are delivered to the setting tools in such relation that their flanges will lie against opposite I sides of the work. A bracket 33 connects and braces the raceways and the hopper-rigidly so that they form a detachable unit, and the bracket is clamped by wing-nuts, as shownat 3 1, to an oscillatory holder by which the delivery ends of the raceways are reciprocated laterally to present the eyelets to the setting tools and then to clear the latter as hereinbefore stated.
