Thisinvention has for its object to construct a machine forsmocking cloth. The machine is designed to successively fold the cloth upon itself or plait it and to connect two of the adjacent folded edges at one side of the cloth at intervals, then to connect one of said connected folded edges to the folded edge next to it at intervals, the connections being made opposite the spaces between the previous row of connections. As a preferable way of folding or plaiting the cloth it is forced down into slots made in a cylindrical or other movable bed and held therein by slats or otherwise, so.

as to present the folded edges which are to be connected. The connections are herein shown as made by metallic fastenings, and the form of fastenings which'l prefer to employ are made of wire bent at or about the middle to present a central depressed portion adapted to enter between the folded edges to be 0011- nected, and also bent near each end to form hooks or clamps adapted to engage the said folded edges. These metallic fastenings are herein represented as formed by suitable mechanism provided for the purpose, after which they are properly positioned and set by suitable setting mechanism likewise provided for the purpose, although said fastenings may be previously formed and delivered to the said setting mechanism.

Figure 1 shows infront elevation a machine for smockin g cloth embodying this invention.

Fig. 6, a detail of one of the cams employed for moving the parts to place the fastening in position to be clinched; Fig. 7,a detail showing a switch on said cam; Figs. 8 and 9, de-

tails showing the means employed for moving secured to a shaft at at a desired distance apart, and slats or bars a rigidly secured to the peripheries of said Wheels or disks at short distances apart. The shaft a has its bearings in the main framework of themachine. To one end of the shaft a a'ratchet-wheel a is secured, which is engaged and rotated by the pawl a connected to and operated by a pawl-carrying arm a, turning loosely on shaft a and connected at the outer end by a rod or to an eccentric a on the'rnain shaft a (See Fig 1*.) As said shaft (1 is rotated continuously the said slotted cylinder will be rotated intermittently. Upon the table b just above the slotted cylinder, a series of independentslats bare placed, of suitable length and width to enter the slots in the cylinder, they being held in place against a cross-bar b by a suitably-weighted presserb, and said table b terminates just short of said cross-bar b so that a narrow slit is left down through which the said slats b are forced one by one by means of a plunger b moving vertically in guides b on the framework. The said plunger 19 is connected by short arms b to eccentrics b on the shaft (i so that at each revolution of said shaft the plunger will make cured to a plate 51, rigidly connected to the framework. The latches are so positioned that when the cylinder is at rest they will stand opposite the spaces which receive the slats, so as to engage the ends of said slats as they are forced down into the spaces and thereby hold them. Besides these locking devices or latches curved flanges 52 extend for a short distance, in continuation of the latched ends, and the slats are made longer than the cylinder, so as to project a short distance at each end thereof, as shown in Fig. 13, to be engaged by the latches 50, and thereafter by the flanges 52 as the cylinder is rotated. At the termination of the flange 52 the slats Z) are released. The cloth 0 thus folded over the rigid bars a of the cylinder is held taut by the removable slats b, as shown in Figs. 10 and 11, and the parallel folded edges, it will be seen, are accessible to be connected together. The slats L are made considerably narrower than the bars (1 and the outer edge of said bars a are provided with aseries of notches 2, eleven being herein represented. To eonnectthe said folded edges of the cloth I employ a metallic fastening, (best shown in Figs. 10 and 11,) which is composed of a piece of wire bent at or about the middle, at 3, to form a central depressed V- shaped portion adapted to enter the spaces between the folded edges of the cloth drawn over the bars a and bent in an opposite direction at or near each end, as at 4 4, to form hooks or clamps to embrace the said folded edges of the cloth upon which they are clinched. This metallic fastening, as herein represented, is formed in the machine; yet it may be previously formed, if desired. The wire taken from the reel e, held in suitable bearings provided for it, is carried forward by two feedrolls 6 c over a die a set in a holder e". A ratchet-wheel e is secured to one end of the roll 6, which is engaged by a pawl c on a pawl-carrying arm 6 connected to an eccentric e on a shaft 6 by a rod e Referring to Figs. 3 and 4, the former for the fastening consists of a nose-piecef on the lower end of the slide-barf, mounted in the frame f on the shaft 6, and two like plates f f pivoted to the face of said slide-barf at f, one at each side of the nose-piecef. This former, when co-operating with the die 6, forms the wire into the desired shape, and as the nose of one of the plates) is squared, and so also one of the side walls of the die 6 the wire, when taken from the reel, is cut off by said squared portions co-operating just previous to the formation of the fastening. The slide-barf has at its upper end a strap or loop f which embraces the eccentric f splined on the shaft e", so that at each revolution of said shaft said slide-bar will be depressed and returned to its normal position. The plates f f are held in their normal position to cutoff and form the fastening by springs f secured to the slide-bar. The fastening, having been formed, clings to the former as the latter rises, thereby removing it from the die. The former, carrying the fastening with it, is then swung on the shaft c as a pivot a little toward the left, (see Fig. 2,) into a position just over the folded edges of the cloth on the cylinder, by means to be described, and the eccentric f is moved longitudinally on the shaft o for a short distance, by means to be described, and then, as the shaft c" again revolves, the former will approach the cloth and deliver the fastening into its proper position, with the central depressed or V -shaped portion between the folded edges and the hooks or clamps embracing said folded edges, as represented in Fig. 10, and when so positioned a cam f on said eccentricf strikes the upper end of a wedge-block f, depressing it against the tension of the spring f so thatitslower wedgeshaped end, which lies between the upper ends of the platesf f acts to turn said plates on their pivots f f causing the lower ends of said plates to each approach the nose-piecef, thereby compressing the hooks or clamps of the fastening on the cloth. As said cam f passes by the end of said wedge-block f, the latter is returned to its normal position by the spring f and said plates permitted to separate and return to their normal position, and as the shaft continues to rotate the former retreats and thereafter returns to its normal position, by means to be described, to form or obtain the next fastening. \Vhile this forming and setting or clinching device for the fastening is herein represented as a single instrument, it is obvious that if the fastenings were previously formed and delivered to the machine said instrument would possess the functions of simply setting or clinching the fastening, and hence the operating mechanism would be simplified.

The means herein shown for moving the forming and setting device from one to its other position consists of an arm 1', secured to a rod 11, held in suitable bearings in the framework, and a link t connecting said arm 2' with the frame f which supports the operating parts of the forming and setting device, and an arm t is secured to said rod 2', which carries a pin i which follows in a cam-groove 1"", formed in the face of the disk i secured to the main operating-shaft a As herein designed the fastening is formed by one complete revolution of the shart e and then set or clinched by the next revolution thereof, and during each operation of forming and setting the fastening the former makes a complete goand-return motion, so I have secured to the shaft 6 a toothed gear g, which is engaged by a like toothed gear 9 on the main operating-shaft, so that said shafts may turn in unison, and I have arranged the camgroove i so that the arm t will be held in one position during one revolution of the main shaft and in its other position during the next revolution of said shaft, and to effectually carry out this result the said cam-groove crosses itself, and at such point I have provided a switch at, which has a single groove or pathway through it, and said switch is turned first in one and then in the opposite direction by a projection on the switch-plug at the opposite side of the disk i striking a pin 9 on the outer end of the arm 1' as said disk revolves, said outer end of the arm i being bent to embrace the disk, as represented in Fig. 7.

As a means of moving the eccentric f longitudinally on the shaft e so that the cam f thereon will strike the wedge-barf at only every other rotation of the shaft, 1 have pivoted to the cross-bar m (see Figs. 8 and 9) a shipper-lever m, which astrides said eccentrio f and the end of said lever enters a diagonal slot 4 in a rod or bar m connected to the arm t and moving in a slot in the crossbar 1%, so that as said rod or bar is moved longitudinally by the vibrations of the arm t'the said shipper-lever m will be turned back and forth. On said shaft e", I will arrange quite a number of forming and setting devices, and while I have herein shown only three, I. will preferably employ many more, and hence the slats of the cylinder are herein shown as notched at eleven different points, as at 2; yet I do not desire to confine myself to the particular number that I may employ, and as two of the folded edges of the cloth are first to be connected together, and then one of said connected folded edges is to be connected to the folded edge next to it at a point opposite the spaces between the previous row of fastenings, I have divided the forming and setting devices into two gangs, so that every other one of the row will operate to set a fastening, and then the remainder will do the same; and for convenience I have so arranged and timed the parts that while one gang is forming the fastenings the other is setting the fasteni n gs, and vice versa. In order to accomplish this result an independent mechanism is provided for moving the forming and setting devices of the two gangs from one position to the other. As herein represented, substantially the same mechanism as above described is employed in connection with the second group, consisting, namely, of an arm 0, secured to the rod 0' and 'connected by the link 0 with the arm of one of the forming and setting devices, and an arm 0 also secured to said rod or shaft, which engages a canrgrooved disk 10, substantially like the cam-grooved disk 13 and constructed to carry out the same result.

In Fig. 2 I have omitted one gang of the forming and setting devices for clearness, al-

though the operating mechanism therefor is shown.

The die-holder e supports as many dies as there are forming devices, and on the rods 7 0 separate arms t' 0 are provided for each forming and setting device, and also a separate shipper-lever for the eccentric thereof, although but one arm, as i and 0 and one cam-groove disk is necessary to rock each rod or bar.

It will be observed that so far as the forming and setting devices of the fastenings are concerned, any other form of folding mech anism may be employed for folding or plaiting the cloth preparatory to connecting the folded edges at one side thereof, and, furthermore, I do not desire to confine my invention to any particular construction of forming and setting devices. If the fastenings are placed in said setting device, they do not need to be constructed to perform the additional functions of forming the fastenings.

When different designs are to be made, those forming and setting devices which are not to be used for setting the fastenings are incapacitated from performing their worksuch, for instance, as removing the wire from the feeding device therefor-and by so doing many different designs may be made.
