BASTENEB-SETTING MACHINE.

. Application filed June 15, 1918.

T 0 all whom it may concern:

Be it known that I, Srnvns'rnn 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 Fastener-Setting Machines, of which the following description, in con nection with the accompanying drawings,-

is a specification, like reference characters on the drawings indicating like parts in the several figures.

v This invention relates to astener setting machines and is herein Shown as embodied in a machine particularly designed for set-- ting compound or two-part fasteners but is not limited to use in such a machine.

In certain classes of work, notably in certain types of shoes and other articles of clothing which are designed to withstand rough usage, it is found that single eyelets for lacing holes are not wholly satisfactory because there is a likelihood that the eyelets will be loosened or even pulled out so as to leave the holes unprotected. Machines have, therefore, been designed for setting eyelets or gromets and washers disposed upon opposite faces of the work and intended to eliminate this di'lficulty. Serious difiiculties have attended this kind of work as heretofore practised and special and expen-v sive machinery is required for speedily and accurately carrying out the setting operation.

It has been proposed to avoid these diiliculties by setting a row of single eyelets from one side of the work and then setting smaller eyelets from the opposite side of the work in telescopic relation with those of Obviously. however, this involves two operations and thedanger of. imperfect alinement between the two sets of fasteners.

An object of the present invention is to provide an improved machine for setting both parts of a two-part fastener in one operation, whether the fastener comprises two telescopic eyelets or a grrnnet and washer, alt-houglnfor purposes of illustration a machine for setting telescopic eyelets has been selected. t will be understood, however, that in referring to telescopic eyelets many considerations apply also to a gromet and washer couple, and that the latter is to be inferred whenever and wherever the facts Specification of Letters Patent.

Serial No. 240,202.

permit, without specific mention of such couple in every case.

In machines for setting gromets and washers it has been found desirable to provide means for centering the- Washer upon the spindle of the set that presents it to the work, and, as this spindle must necessarily be of small enough dimensions to enable it to pass through the barrel of the cooperating gromet or eyelet, it follows that the washer will be loose relatively to-the spindle, and some difficulty has therefore been experienced in preventing interference between the end. of the eyelet barrel and the inner edge of the washer. In assembling two eyelets intelescopic relation the same difhculty has been found, namely, that of preventing interference between the barrel larger eyelet.

Another important feature of the invention, therefore, consists in improved means for presenting and guiding eyelets into telescoping relation in the work. Accordingly the means for this purpose, as shown, is such that coaxial relation of the eyelets is insured when the smaller eyelet is about to enter the larger eyelet. In the preferred embodiment, the larger or reinforcing eyelet is presented to the .lower side of the. work by a setting tool that has a concentric pilot formed integrally therewith. This pilot is preferably tapered and is so long that its leading end will pass completely through and beyond the work to receive the end of'the barrel of the smaller eyelet and to guide it through the hole in the work and into the barrel of the larger or reinforcing eyelet. For the purpose of this application, the larger eyelet is called the reinforcing eyelet because it takes the place of a washer, and, in the novel arrangement .herein described, it may or may not be clenched upon the work. Preferably the barrel of the smaller eyelet is initially contracted or tapered at its free end. -Two uses are made of this feature, to wit, the eyelet is first friotionally supported above the work by clinging engagement with the depressible spindle of the top set, and, as the eyelet is forced downwardly by the upper setting tool, it is held seated against the tool by its gripping efiect on the taperi r pilot of the bottom set as it is guided by flie pilot into the Work and into the barrel of the larger eyelet. It will. be seen that, owing to the tapering of the pilot on the lower set, the leading end of the barrel of the smaller eyelet is gradually stretched as it progresses along the pilot and the initial contraction of the leading end is wholly eliminated before the latter reaches the clenching surface at the base of the pilot. In the setting operation, as the two eyelets are substantially simultaneously presented to opposite sides of the work, the barrel of the larger eyelet will be supported by the tapered pilot until it engages and is guided upon the outside of the barrel of the smaller eyelet in the passage through the work. The pilot preferably tapers faster than the barrel of the reinforcing eyelet does so that a space isinsured between the two for the ready admission of the barrel of the smaller eyelet.

It will be noted that in case there is a variation in the thickness of the work or in case the setting tools are not properly adjusted in the machine, there is no possibility of a buckling of the barrel of the smaller eyelet because it is supported from within by the tapered pilot-0f the bottom set and from without. by the barrelof the larger eyelet. The maximum holding eifect of the eyelets may be obtained when the barrel of the larger eyelet is long enough to be clenched against the work by engagement with the flange of the smaller eyelet as the latter is supported by the top set, but it is not alto- .the foot of the wearer.

gether necessary that the larger eyelet should be clenched upon the work since it will be tightly anchored by the clenching of the barrel of the smaller eyelet in engagement .with its flange.-

It will be seen that the upset end of the inner eyelet is necessarily exposed and when it is arranged upon the inside of the shoe, for example, it is desirable to make it as smooth as possible in order to avoid chafing To this end it has been proposed to roll the upset end of the barrel, but heretofore, so far as I- am aware, this rolled end has projected'beyond the plane of the surrounding flange of the washer or eyelet, as the case might be.

For the purpose of avoiding such projecting relation another feature of the invention consists in a setting tool having an upsetting surface disposed above the plane of the seat that supports the flange of the larger eyelet. In order to obtain the eatest advantage from this feature the barrel of the outer or reinforcing eyelet is preferably flared adjacent to the point where the flange joins it and the leading end of th inner eyelet is turned back and clenched in the space so provided in the barrel of the reinforcing eyelet.

The invention is illustrated as embodied in a machine of the type set forth in Letters enses following specification. In the drawings,--

Figure 1 is an angular view of a machine constructed in accordance with this invention;

Fig. 2 is an elevation partly in section'of the operating tools disposed in the positions which they occupy when the machine is at rest and viewed from the opposite side of the machine;

Fig. .3 is a similar view showing the punch and punching block in cooperating relation to make an aperture in the work;

Figs. 4 and 5 are similar views showing successive positions of thesetting tools;

Figs. 6 and 7 are enlarged sectional views showing the relative positions of the setting tools as the eyelets begin to telescope and the final setting position of the tools; and

Figs..8 and 9 are enlarged fragmentary views of the sides of the hopper.

Reference is made to the Goddu Patent No. 934,066 above mentioned, for a more complete description of partsof the machine not herein fully described. Such a machine comprises a pivoted U-shaped frame 10 whose arms are provided with bearings for the cotiperating oppositely disposed tools. Striking members 12 are supported upon levers 14 pivoted in a frame 16 and are arranged to strike against the outer ends of the cooperating tools to bring them toward one another and into operative relation with the work. ing tools may be conveniently accomplished by means of a spring actuated lever 18 which may be constructed in accordance with the arrangement described in Letters Patent of the United States No. 1,122,310, granted December 29, 1914, upon an application of Fred A. Rumney. The work maybe supported between the tools by a rigid plate 20 bearing against the top side of which is a spring pressed foot 22 of Well known construction. An edge gage 24 is provided in connection with the plate 20.

The punching of the work may beeflectcd through the bore of the punch and drop out below the level of the Work. By reason of this arrangement, there is no possibility that The retraction of the cooperatearner.

these punchings Will get caught between the operating tools or the fasteners and the Work. Furthermore, the tapered exterior of the punch slightly enlarges the size of the hole at the lower face of the work and thereby makes it more perfectly adapted for the reception of the barrel of the larger eyelet which will be presented thereto by the lower set in a manner to be later described. From an inspection of Fig. 3 it will be seen that the punch block is arranged to move to a posi tion just at the top face of the work as the latter is supported by the plate and the said work plate, being close beside the tubular punch, helps to strip the work therefrom in case there is any sticking of the punch in the work as the punch recedes.

The lower setting tool 40 is provided with a fixed and preferably integral tapered pilot 42 and surrounding this pilot is an annular upsetting surface 44 slightly raised above the general level of the face of the tool 40 and designed to upset the barrel of the smaller eyelet which is guided thereagainst by the pilot 42. Surrounding this upsetting surface 44 is an annular concentric seat d6 which is adapted to receive and to support the flange of the larger reinforcing eyelet as it is presented to the work by the tool 40. It will be noticed that the general level of this seat 4-6 is slightly below the level of the groove 44 so that the upset end of the barrel of the smaller eyelet (see Fig. 7) is slightly within the level of the outside of the embossed flange of the larger eyelet when applied to the work. The upper setting tool 50. is maintained in alinement with the tool 40 by the frame 10 in the usual fashion and is provided with a spring expelled depressible spindle 52 having its outer end slightly tapered at 54 and provided with a conical recess 56 to receive the point of the pilot 42. Surrounding this spindle is an annular groove 58 adapted to support the flange of the smaller and upper eyelet as the eyelets are brought into telescoping relation in the work and are secured therein by the action of the setting tools.

Eyelets of different sizes, that is to say, having barrels of different sizes, are then applied to the respective setting tools by means of raceways 60 and 62 of usual and ordinary construction which are supplied from a hopper 64. This hopper is adapted to be filled with an indiscriminate mass ofeyelets of different sizes or characters and is provided with the usual seriesof ports adjacent to its lower edge upon the two sides to permit the outward passage into the raceways of properly disposed eyelet It will be noted, however, that the ports ofi leading to the lower raceway are lower and broader (see Fig. 9) than are the ports 68 (see Fig. 8 upon the opposite side of the hopper and communicating with the upper and 9 it will be seen thateyelets 70, which it is desired to deliver to the upper raceway, are

provided with relatively long and narrow barrels whose outer ends are flared inwardly while the eyelets 72, which it is desired to deliver to the lower raceway, are provided with relatively short broad barrels whose outer ends are substantially cylindrical, i. 6. with parallel sides. By reason, therefore, of the arrangement of the ports of the hopper, only one type of fastener can pass into either of the raceways and even though the fasteners become nested, as shown in Fig. 9, they cannot pass out into either of the race; ways. The usual agitator 74 serves constantly to stir up the mass of eyelets in the hopper and tends to disengage those eyelets which have become nested.

The general operation of the parts of the machine is very similar to the operation of the corresponding parts of the machine shown in the Goddu patent. A piece of work 76 having been inserted between the presser foot 22 and the work plate 20 and against the edge gage 24, the'punching tools come together-at a predetermined point and make a hole in the work and then, because of a movement of the U-shaped frame 20, move out of alinement with said hole and bring the oppositely disposed setting tools into alinement therewith. The ends of the raceways then move into alinement with said tools to allow the threading of the endmost fasteners therein by the spindle and pilot respectively of the upper and lower tools and move again out of alinement with the tools leaving the eyelets upon said spindle and pilot respectively. In applicant's novel arrangement, however, the eyelets delivcred to the 'lower tool are provided with a relatively short, broad barrel while those delivered to the upper tool are provided with a relatively narrow, long barrel. Preferably the eyelets delivered to the upper tool have the outer ends of their barrels flared inwardly and are frictionally engaged by the slightly tapered lower end of the de pressible spindle 52 of the top set. Because of the angular position of the setting tools, a fastener delivered to the lower tool will hang loosely upon the fixed pilot 42 and for piece of work, the spindle 52 of the top set pered pilot 42 of the bottom set.

will meet the pilot 42 of the bottom set at approximately the level of the work and will be forthwith pushed back into the top set as the two tools are still further brought together. During this time the outer and upper end of the fixed pilot 42 will have completely traversed the aperture in the work and, as it depresses the spindle 52, will release the smaller eyelet from frictional engagement with the spindle at the top set and allow the same to drop into engagement with the upper end of the fixed pilot. The continued approach of the setting tools will bring them to a position such as shown in Fig. 5 where the top set is starting to push the smaller and upper eyelet on to the ta- The arrangement is preferably such that the inwardly flared upper eyelet closely engages the tapered pilot near its outer end and as it is then pushed downwardly along said pilot its flared end is stretched outwardly slightly so that the engagement-- between the barrel of the upper eyelet and the surface of the pilot 4-2 is always maintained. This arrangement and the spacing of the barrel of the larger eyelet and the pilot insuret-he perfect telescoping of the upper and lower eyelets when they are brought into adj ace'nt position such as shown in Fig. 6, and, as soon as the barrel of the larger eyelet supported by the lower set 40 reaches the barrel ofthe smaller eyelet, it will pass outside the same and be guided through the work by engagement with the outer surface of said barrel. The continued approach of the setting tools will cause the barrel of the smaller eyelet to be upset nd preferably to be sharply curled over against the upsetting surface 44 of the bottom set at a level slightly within the level of the outside of the flange of the larger eyelet. By reason of this arrangement, a very smooth surface is secured upon the lower side of the work.

' In the making of shoes, for example, this lower side will ordinarily be the inside of the upper and it is, therefore, very important that the fasteners when clenched in the work shall present as smooth a surface cure /othfasteners in the work. Prefer-.

ably, however, .the barrel of the larger eyelet is made of such a. length that it is upset and clenched against the work by the ennausea gagenient with the inside of the flange of the smaller eyelet as the same is supported by the annular groove 58 in the top set. In case of variation in the thickness of the work or in case of improper adjustment of the machine, there is no possibility of buckling of the barrel of the smaller eyelet because it is supported from within by the rigid pilot 42 and because it is supported from. without by the barrel of the larger eyelet. ,A perfeet opening of-uniform size through the cooperaing fasteners is, therefore, ,insured.

The feeding of the work to space -,the eye lets" may be accomplished in the usual eration of the machine or when it is desired only to punch the work.
