FEED MECHANISM FOR LACING-HOOKETTING lv'Ij-LGHINES.

To all whom t may concern:

Be it known that I, ARTHUR R. Havanna, a citizen of the United States, residing at lhalthain, in the county of Middlesex and State of Massachusetts, have invented .new

and useful Improvements in Feed Mecha` nism for Lacing-Hook-Setting li/laehines, of which the following is a specification.

lThis invention relates to an improvement in feeding mechanisms for lacingl hook setting machines, the same being particularly adapted for use in connection with machines of the class shown and described in the United States patent issued to me November 29, 1910, for machine for settiiig lacing hooks, No. 977,090, to which reference may be had.

y whereby the upper of the shoe is punched and fed should be such that the punch will be firmly and accurately held in position during the punching and feeding,` operations, whether said punch is used in a machine wherein a female die cooperates with amale punch during the punching operation, said punchbeing subsequently utilized to feed the upper of the shoe forward into proper position with a lacing hook set therein, or whether said male punch cooperates with a plate during the punching operation and subsequently is moved laterally thereof to feed the upper along the `upper surface of said plate after the setting of the lacing hook has taken place. lt is well known. to those skilled in the art that the accurate 'location of the male punch relatively to the female die or plate coperating therewith must be maintained in order to secure practical results in the punching and feeding' operations. y

The object of this invention, therefore, is to so hold and sustain a punch during the punching and feeding operation that the relation of the punch to the die shall be accurately maintained. Prior to this invention it has been customary to guide the punch holder by means of guide rods located `one above the other. The objection to thisl Speecaton of Letters Patent.

construction resides in the fact that there is liability7 of the punch tipping-slightly on its supporting guide rods laterally and this destroys the accurate relation of the punch to the part cooperating therewith, whether it be a female punch or a die plate.

lt is also very desirable in machines of this class to have the punch holder accurately and firmly supported during' all its operations of punching and feeding, and to make said holder lieght in order that it may be fed with rapidity without jarring); the machine. In automatic machines of the class to which this invention relates the punching and feeding operation is very rapid, being at a rate of three hundred and fifty to five hundred rotations or complete operations per minute.

It is, therefore, the object of this invention to provide a holder which, while supported firmly duringg all its different operations, shall be light and durable in its construction.

To these ends the invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a front elevation, partly broken away and shown in section, of my improved feeding mech anism shown in connection with a lacing hook setting machine. Fig. 2 is a sectional elevation taken on line 2?, of Fie'. l illustrating a punch Vholder and the slide by which a vertical reciprocatory motion is imparted thereto. Fig. 3 is a sectional plan taken on line 3-3 of Fig. l. illustratinn* the punch holder andthe mechanism by which vertical and horizontal reciprocatorv movements are imparted thereto. Fig. 4 is a detail sectional plan taken on the irregular line 4 4 of Fig. 1 illustrating the portion of the mech anism by which a horizontal reciprocatory movement is imparted to the punch holder and punch.

Like numerals refer to like parts throughout the several views of the drawings.

lin the drawings 5 is the frame of the Inachine.

6 isa vertically movable slide to the rear side of which is attached a block 7 having a curved slot 8 provided in its rear face in which is located a sliding block mounted on a crank-pin 10 fast to the crank 11, said. crank being fastened to a shaft 12 rotatably mounted in suitable bearings 13 in the frame of said machine. A rocking motion is imparted to the shaft 12 by a crank 14 fast to the rear end of said shaft and connected by a rod 15 to a. rocker plate 16 pivoted at- 17 to the frame 5.

The rocker plate 16 has two cam rolls 18 and 19 journaled thereon and bearing against opposite sides, respectively, of the cams 20 and 20. The cams 20 and 20 are fastened to the main driving shaft 21 of the machine, said driving shaft being rotatably mounted in suitable bearings on said frame 5. By means of this mechanism a rocking motion is imparted to the rocker plate 1G and, through the rod a rocking motion is imparted to the rocker arm 14, the shaft 12 and the arm 11, which results in a movement of the sliding block 9 longitudinally of the slot 8 in the plate 7 and a resultant reciprocatory movement is impartedto the slide 6.

The slide G is provided at its lower end (see Fig. 2) with lateral projections 22 and 23', in which are clamped ay pair of guide rods 24 and25. Said guide rods are preferably tubular in form in order to render the device light, and are located on opposite sides, respectively of the slide 6, with their median longitudinal lines lying in substantially the same horizontal plane, said slide (3 being suitably guided in bearings 26 and 27 provided in the frame 5.

A punch 2S is fastened to a holder 29 which ismounted to` slide horizontally on the guide rods 24' and The guide rods 24 and 25 are clamped to the lateral projections or ears 22 and 23 by means of clamp screws 30 and 31, respectively, said clamp screws having screw-threaded engagement with ears 32 and and rotatable' engagement' vith ears 34: and' 35, said ears 32 and and 33 and 35 being obtained by splitting the lateral projections 22v and longitudinally and horizontally thereof'. V

The holder 29 has two bosses 3G and 37 thereon adapted to slide on the guide rod 24 and two bosses 3S and 39 thereon adapted to slide onv the guide rod 25, so that said holder is firmly supported at four points upon said guide rods 24 and 25. rlhe bosses 36 and 37, it will be noted, are located on the opposite side ofthe slide 5 from that upon which the bosses 38 and'39 are located.

A; reciprocatory movement is imparted to the holder 29 by an arm 40'fast toa vertical rock-shaft 41. Said' arm isbifurcated at its free end and has fastened thereto' a rod 42which passes through a sliding block 43 located in a. slot 44 on the holder 29. The arm 40 is clampedV to a vertical rock-shaft 41 by means of a clamp screw 45.y The rockshaft' 41 is mounted in suitable bearings 4G and 47 on the frame 5, andtto' the lower end of'V said rock-shaft is' fastened an arm 4S provided upon its upper face with index graduations 49. A. link 5() is pivotally connected by a pin 51 to the arm 48, said pin being adapted4 to engage teeth or corrugaltions 52 provided on one side of a slot 53 in said arm; Said pin is withdrawn from engagement with said teeth by a lever 54 which is pivoted at 55 to the under side of the arm 48 (see Fig. 1). A spring 56 holds the pin 51 in engagement with the teeth 52 and when it is desired to disengage said pin 51 from said teeth, the lever 54 is raised at its outer end, the pin 51l thus being depressed andv drawn out of Contact with the teeth 52. it this time the link 50' canbe rocked, by means of the handle'i', upony its pivot 58 to any desired location and said locati i indicated by means of" an index linger o9 fast tosaid-link. reciprocatory motion is imparted to the ar1n48 and to the shaft by means of camslide 50 to which said link is pivoted at Said cam slide is mounted upon rods 61 and G2' fast to the frame of the machine (see Fig. 1), and-upon said cani slide two roll's 63? and 64 are rotatably mounted, said rolls being locatedon opposite sides, respectively, of two cams and 65 which are fastened to the main@ ing shaft 21, so that as said main driving shaft rotates the slide 60 isreciprocated and a reciprocatory motion is thus imparted to the link 50 and by it a rockingK motion imparted to the arm 4S, rock-shaft 41 and arm 40, whereby a reciprocatory motion is imparted to the holder 29and1 the punch 28 fast thereto. l

The general operation ofthev mechanism hereinbefore specifically described is as follows: A rocking motion is imparted to the shaft 12 through the cranks 11 and 14, connecting rod 15 and cam 20`to movethe slide 6 downwardly and; drive the punch 2S through the upper, which is at that timelecated upona work supporting plateGG. rPhe upper is held in position at1 this time by a presser foot 67 in a manner describedinsaid Letters Patent; The punch 28, with its h older 29, is forced: downwardly by the slide 56 to punch a hole in the leather, at this time cooperating with a suitable female die or plate, such for insta-nce, as illustrated' and described said Letters Patenti The lacing hook is thenv set in the upper andI a lateralv motion is then imparted to the punch through its holder 29' and" the connections hereinbefore described' by which a horizontal movement is-impa'rted'to said'holder and said holder slides alongl the guide rods24 and 25, thus feeding* the upper along the worksupport 66. At the end of the feeding movement of the upper the slide 6 is actuated to withdraw thepunchvfromt said upper, and after said punch has been so withdrawn, it is moved toward the right (Fig. 1) by its-holder 29 y and theconnections'by which a" horizontal movement is imparted to said holder, hereinbefore described, thus bringing the punch and .its holder back to the position illustrated in F ig. l, in readiness to punch another hole, feed the upper, and have another lacing hook set therein, as fully described and illustrated in said Letters Patent.
