MACHINE FOR. SETTING LACINGr-I-IOGKS AND THE LIKE.

Application filed March 2, 1909.

T all whom it may concern:

Be it known that I, ARTHUR lV. HAR- onavns, of Boston, in the county of Suffolk and State of idassachusetts, have invented certain new and useful Improvements in Machines for Setting Lacing-Hooks and the Like, of which the following is a specification.

This invention relates to machines for set ting lacing hooks, eyelets and articles of like nature in shoes, etc. Its objectis to provide a gang machine adapted to take a number of such articles from a single raceway and set them in one operation, subsidiary to which object is that of separating the hooks prior to setting, so that they will be spaced to correspond with the setting dies or anvils, which are arranged in accordance with the spacing which the hooks are to have on the shoe upper. Accordingly, the main feature of the present invention is the spacing transferrer, which is adapted to take a number of hooks from the raceway or other container in which they are held in order, and advance them to the setting dies, spreading them so that they will be correctly located with respect to the anvils by which they are clenched.

The invention consists also in the mechanism for carrying the above-noted objects into effect, and in details of construction, which are hereinafter fully set forth and cl aimed.

Of the accon'ipanying drawings,Figure 1 represents a plan view of a machine embodying my invention. Fig. 2 represents a longitudinal section of the machine on line 22 of Fig. 1. Figs. 3, 4 and 5 represent detail plan views of the feeding device, showing the same in three different positions. In Fig. 3, it is in engagement with the hoo {3, ready to feed them to the setting device; in Fi 4, it has thus fed and separated the hooks and in Fig. 5, it has retracted clear of the setting die. Fig. 6 represents a plan view of a modification.

The same reference characters indicate the same parts in all the figures.

In the drawings, 1 represents a base or table to the top of which are secured brackets 2, each of which carries a setting die or anvil 3. These brackets and anvils are stationary except for the adjustment which is permitted by the slots 4 through which their securing bolts pass. Extending downward Specification of Letters Patent.

' from the table is a vertical guide 6 in which reciprocates a plunger 7 carrying a setting die 8. The latter projects through an aperture in the table and has a lip 9 suitable for holding lacing hooks 10 with their tubular shanks upward. The flange S) of the die is a shelf, the edge of which conforms to the line in which the lacing hooks are set, and this edge, when the plunger 7 is in normal position, is in line with the plate 11, forming part of a raceway by which the hooks are conducted from a convenient magazine or on which they are previously placed in any suit able way. The anvils 3 are above the die 8 and the hooks are set by elevating this die. In the front of the table is a recess flanked by guideways 12 and 13 in which is contained a slide 14. This slide is movable toward and from the raceway and forms part of the feeder for sliding the hooks from the raceway to the lower die 8 The transferring elements consist of fingers 15 formed on bars 16 which are pivoted by means of studs 17 or other pivotal connections on the plate 14. A bar 18 extends across the fingercarrying bars 16 and is secured to each of the latter by fastening screws 19 or the like.

In the operation of the machine the slide 1%, which normally is in the position shown in Fig. 1, is advanced so tln t the fingers pick off a number of hooks from the series on the raceway, one finger passing beside the tubular shank of each hook. The fingers are then moved toward the left and at the same time separated so that the hooks are advanced to the setting instrumentalities, one hook being under each anvil. The lower die is then lifted until the hook shanks are brought against the anvils and the hooks are set. The mechanism for giving these motions to the machine consists of a shaft 20 driven by any suitable means, as a pulley 21, on which shaft are mounted cams 22 23 and 24;. The cam 22 operates the slide 1% through a. bar 25 connected with the slide by a pin 26 and bearing on its rear end a stud 27 naving a roll 28 contained in a groove 29 of the cam. The cam 23 has a groove 30 which receives a roll 31 carried on the side of one end of a bar 32 which passes through a guide 33 on the upper side of the table and has a stud 3t entering a recess 35 in the bar 18, before described. The third cam 2st operates the setting dies by means of a slide 36 passing through a guide 37 secured to the under side of the table 1, and connected with toggle levers 38 and 39, the former of which is ivoted to the plunger 7, and the latter to the guide 6. The connection between the slide 36 and toggle is through an arm 41 of the slide which has a slot 42 receiving the knuckle pivot 43 of the toggle. The rear end of the slide carries a roll 44 contained in a groove 45 of the cam 24. The grooves of the several cams are so shaped and timed that when the machine is started, the first part of the shafts rotation carries the slide 14 forward. A dwell of the cam groove 28 then causes the slide to remain stationary, while the cam 23 causes the fingers to feed hooks from the raceway to the plunger beneath the several anvils. A dwell in the cam groove 30 then allows the fingers to remain in their offset and spread condition while the slide retracts. Finally, the cam groove 45, which has a single abrupt offset and is concentric through the greater part of its extent, raises and lowers the plunger 7. lVhile the plunger is being lowered, the slide 32 which spreads and closes the fingers, is returned to normal position and the fingers brought back to the position illustrated in Fig. l.

The end of the bar 18 which contains the recess is formed as a frame having two cam surfaces 46 47 connected by intermediate sides 48 and 49 which are provided to permit the necessary movement of the slide 14 back and forth without displacing the fingers. When the fingers are closed together, the side 48 is parallel to the line of movement of the slide 14 so that this side travels along by the pin 34 without affecting the position of the fingers, until the pin is at the angle of the sides 48 and 46, as shown in Fig. 3. Upon the bar 32 being then moved in the direction of the arrow on Fig. 3, the pin acts on the cam edge 46 and displaces the bar 18 to the right, swinging the finger-carrying bars 16 about their pivots 17. As the pivots are at varying distances from the ends of the fingers, the right-hand pivot being nearest the raceway and the lefthand pivot farthest therefrom, the left-hand finger travels farther than any of the others, and the right-hand finger has the least travel, the intermediate fingers being moved in proportion, so that the hooks engaged by the various fingers are moved variously, but by such amounts that they are evenly spaced. The positions of the pivots and the lengths of the fingers determine the distances through which the hooks are fed, and by suitably designing these features, the hooks may be given any spacing desired, and the machine may be adapted to any class of work. When the fingers are spread, as shown in Fig. 4, the side 49 is parallel to the travel of the slide 14 so that the fingers are not disturbed while the slide retracts. The

retractive movement brings the pin 34 iii the angle between the edges 47 and 49 so that the final movement of the bar 32 rearward restores the transverse bar 18 to the normal position and closes thefingers- It will be understood that that portion of the invention which relates to feeding and spacing the hooks is not necessarily limited to machines adapted to set lacing hooks alone but may be applied to machines for setting eyelets, rivets, or any other device of similar nature which may be set in gangs. I desire to make it also understood that I do not limit my invention to the number of feeding fingers shown, but propose to use more or less with any provision for adjusting them so as to vary the spacing of the hooks or other articles, that may be desirable.
