await-MAKING AND GLEAT AND Application filed May 2,

L invention relates to .anappro; aring handles to be subsequently attachedas by soldering to can ends, the handles so prepared being of the well know type comprising a rectangular or similarly formed loop of wire secured to "the canv end by means of a sheet metal clip or cleat, said cleat embracing one side of the wire loop to form a hinge "joint to permit said loop either to lie'fiat upon the can end, or to beswung at right angles thereto when, used as a handle.

The object of the invention is to provide a simple automatic machine for forming. the shcet metal cleats and a mhnng the same with the previously forms ire loop in such a n anner that they cannotbeaccidentally ated therefrom during subsequent han- As a result the assembled cleats and in a condition to be attached to can ends by solderor any other well known method and may be'handled orshipped without any 161 precautions to prevent a separation loops are discharged from the machine {Ether objects and advantages ofthe present. invention will be apparent from the follow i specification and the accompanying drawi s in which is described and illustrateda preferred embodiment of the said invention. It is to be understoodthat the form. proportion. and arrangement of the several pa ts comprising the machine maybe varied within the limits ofthe claims hereto appended without eparting from the spirit'of the infrention. 7

I i In the drawings,.thereference numeral 1 designates the bed ofth'e machine, and 2 asuperstructure rising therefrom and supporting a rotatable shaft 8 provided with a driv 111 side source,' not shown. The shaft 3 is pro videdwith acrank 5,1 1, oonneetedlby a pitman 6 with a vertical reciprocable head '7, the latter operating in suitable guides 8 secured to the superstructure 2. Abracket 9, FigsQl and 2, extends laterally from the pulley 4 for receiving power from an out'-:

head 7 and is connected by a link 10 with an- I oscillatorymember 11,,j0urnalled about shaft 12, Fig. 2. 'Themember 11. carries a pawl 13- adapted to, engage aratchet wheel" member'22 formed. inthebed 1,:the flights of said chain travelling in agroove 23 as shown in Figsll and 8.'- f

The drive shaft 3 carries acam 24 at one end; as shown in Fig. 1, and said cam operates a lever QSeXtending upwardlyfromaiid secured to a shaft'26 Figs. 1.and;2.. A lever 27 secured to said shaft 26extends downwardr' ly therefrom and isconnected by a-link 28 with a slide 29; The slide 29- is adapted ,to' be reciprocated horizontally beneath a holder 80, Figs. 1, 2 and-8, adapted to contain a stack of previously -;formed wire loops 31 tal central portion 33 extending to the groove f 23 and with downwardly inclined end portions 34, as shown. Thus the loop 31 when pushed out from beneath the holder 30 by the slide 29 remains in a horizontal position until its forward bar 31 drops off the end of the horizontal guideway portion 33. The inclined guideway portions 34 then permit the loop to assumera vertical position in the slot 23 as a result of the continued advancing movement of the slide 29. p The loop 31 is thus fed into the groove 23 and falls upon the conveyer chain-19 in a position to be engaged by one of the flights 20 thereof as shown in Fig. 2. i

The oscillating shaft 26, Figs. 1 and 2, is also provided with a second downwardly extending lever 35, which is connected by a link .36 with a feed slide 37. The "latter is adapted toreciprocate horizontally be neath a'holder 38, Figs. '3 and 4 adapted .to contain'a stack of cleat blanks 39, Figs.

3 and. 10, and by said reciprocation to successivelyslide the lowermostot said blanks out from beneath'the stack within said holder, and to position the removed blank across the slot 23,-as shown in Fig. 3. The opera tions of the respective slides 37 and 29 and the conveyer chain 19 are so timed as to cause the cleat blank 39 to be pushed through a positioned wire loop 31, as shown in Figs.

I 3, 4 and 5. The wire loops, after being engaged by the flights 20 of the chain 19 and removed from the sphere of action of the teed slide29, as shown in Fig. 2, are subsequently advanced through a continuation of the slot 23. by contact with. each other, as shown in Fig. 5, and the various parts are so timed and related that. when. the conveyor chain. 19 comes to rest one wireloop will be positionedin transverse alignment with the cleatblank feedslide 37, so that by the operation of the latter, as described above, a cleat blank is slid horizontallythrough said positioned loop 31. A suitable guideway 40 is provided for insuring the proper travel'ot the cleat blank 39 from its holder 38 to its assembling At this assembling position, as shown in Figs. 3 and '5, the loop 31 rests upon a ver tically movable plunger 41 suitably mounted in the bottom of the slot 23 and pressed upwardly to its normal position in alignmentwith the bottom of said slot by a spring 42. Thereciprocating head 7 carries at its lowei end a die 43 positioned-in vertical alignment with the yieldable plunger 41.

In this position also, the cleat blank 39 rests upon a pair of reciprocable slides 44 and 45 lying on'each side of the groove 23. The

slide 44 is provided with an inclined aperture 46 through whichpasses a bar 47' secured to the head 7 and provided withan inclined portion 48. It will be readilypunden stood from Fig. 3 of the drawings that when the head 7 descends from the position shown, the slide 44 is moved to the left by the contact of the inclined portion 43 ot the bar 47 with the inclined slot or aperture 46 formed in said slide. of the head 7 also causes the lower end or: the bar 47 to contact with bell crank lever 49 fulcrumed as at 50 and provided with a connection at 51 with the slide 45' so that said slide 45 is moved to the right simultaneously with the left hand the opposite side 44. v

Figs. 3 and 5 show the relative positions of the parts immediately prior to the beginning of the assembling operation. The die wire loop and forming a bearing for it in which the loop is rotatably retained. The

movement of The same movement 3 oppositely disposed slides 44 and 45 are then i moved towardeach other until at the conclusion of the o aeration the carts are in the accidental separation therefrom. The slide 7 then retreats upwardly, the oppositely disposed slides 44 and 45 are aga n separated and the assembled handle is pushed away from the sphere of action of the assembling mechanism by the advance of the next fol-- lowing wire loop. The assembled handles,

shown at 53 in Fig. 2,- may be discharged: from the machinein'any convenient manner,

not shown in the drawings. 7

It will be readily understood from the foregoing that the operation of the mach e, which is entirely automatic, comprises ihe successive feeding of the wire loops 31 fronr their holdeiythesuccessive positioning of the cleat blanks39 within said loops, and the sno cessive forming of the cleat blanks into cleats by partially wrapping them around the wire loops.

At each movement of the conveyor, 'chain'19, a loop 31 is carried intoasseznbling position, and durlng the succeeding period 1rd I of rest of said chain 19, a cleat blank positioned within said loop and is formed into a cleat and assembled with said loop'tw make the completed handle shown in Fig.12.

shown in Figs? and 12, the completed han dles may be subsequently operated on or shipped without any danger of their-component parts becoming separated.
