PLAlTlNG- MACHINE.

- tion.

This invention relates to a machine for making plaited and other folded goods, and which is provided with mechanism for sewing the plaits or other folds together when formed. The machine is so constructed that the sewing devices and the feeding devices operate intermittcntly and not continuously, and thus a number of plaits may be formed and superposed before being sewed together. In this way a Variety of patterns may be produced which cannot be made in machines that sew continuously.

Theinvention consists in the various features of improvement more fully pointed out in th following description and claims.

In the accompanying sheets of drawings, Figure 1 is a side elevation of the machine with the overhanging needle-arm removed. Fig. 2 is a vertical transverse section on line 00 m, Fig. 5. Fig. 3 is a detail view of part of the driving-shaft. Fig. 4 is a bottom view of the main part of the machine. Fig. 5 is a top view of the machine without the needle-arm. Fig. 6 is a longitudinal section on line 11 3 Fig. 5. Fig. 7 is a perspective view of the machine.

The letters a a represent a pair of gageplates, of which the plate (it receives up-anddown motion, while the plate a receives upand-down motion as well as reciprocating motion. Between these plates the fabric placed on feed-table b is folded or plaited, as is well known. The motion of plate a is received from work-shaft 0 through gear-wheel d and connecting-links e e, while the plate a in turn operates plate a by pins f, attached to plate a. A presser-foot, g, placed between the gageplates, descends every time the gage-plates are at their greatest proximity, to bind the folded fabric in place. This presser-footis operated by a cam, h, on a transverse shaft, 2', that receives motion by gear-wheel d from workshaft 0. x

The parts thus far described operate substantially as described in Patent No. 331,432,

granted to F. Panse,December 1, 1885, and are not the subject of the present invention,

This invention consists, essentially, in the employment of a looper and a feed-bar that are alternately put in and out of motion, the mo tion being imparted to these parts when the plate a recedes from the platea to come into position for the formation of one or more new folds.

To carry this invention into effect the machine is constructed as follows:

To the shaft 6 there is affixed a cam, 7', against the face of which there is held one end of a pivoted bar, k. This bar is perforated for the admission of a tubular shifting clutch, Z, surrounding one end of work-shaft c, and adapted to engage a counterpart shoulder, m, on workshaft 0, the faces of the coupling members having coacting projections and interdental spaces.

To the end of clutch Z there is connected a shaft, it, upon which are mounted the looper and the cams for operating the feed-bar, as is hereinafter described. 7 5

l is a shoulder upon clutch Z and bearing against one side of pivoted bar k, against which it is pressed by a spring, I, and in this way the end of the pivoted bar is held against the working-face of the cam j.

By means of the parts thus far described the clutch Z is reciprocated upon the work-shaft cthat is to say, when the bar It bears against the protruding surface of the cam j the bar will be pressed against shoulder Z to compress 8 5 the spring Z and to keep the clutch out of engagement with its counterpart shoulder m,- but when the bar Z: is brought opposite the receding surface of the cam j the spring 1 will be at liberty to throw the clutch Z into engagev9o ment with shoulder m. The result will be that the rotary motion of the shaft 0 will be transmitted to the clutch l and with it to theloopercarrying shaft a, while when the clutch is out of engagement such shaft n will receive no mo- 5 tion. The surface of the cam j may be made in a variety of shapes, so as to operate the clutch at any desired period. Thus the clutch may be thrown into engagement after the machine has shaped one fold between its gagemo plates or after it has shaped two or more folds. Upon the shaft 11. there is mounted the looper 0 or needle-hook, operating in conjunction engaged by two cams, 1' s, on shaft n.

with the needle to form the stitches whenever the looper is revolved. The shaft on also earries the cam or cams for reciprocating and raising and lowering the feed-bar 1). Thisfeedbar projects through a slot in the work-table, as usual, and is attached to a slotted slide. q, This slide turns upon a pivot, t, and is moved backward by the cam 0', while it is thrown forward by spring u. The np-and-down motion of the feed-bar isimparted to it from slide (1 by means of the cam s. Vhen the clutch Z is out of engagement with the working-shaft, the looper and the feedbar will be at rest; but when the clutch is revolved by engagement with the work-shaft it will revolve the looper 0 and the cams 1' 8, thus causing the formation of the stitch and the proper presentation of the work to the needle.

What I claim is- 1. The combination, in a plaiting-machine, of a shaft, 0, with a looper-earrying clutch and with a pair of gage-plates and links for transmitting motion to the gage-plates from the shaft, and with a cam and a pivoted bar operated by the cam and adapted to throw the clutch alternatelyint-o and out of engagement with the shaft a, substantially as specified.

2. The combination, in a plaiting-maehine, 0

of the following elements: a work-shaft, a clutch, a looper, and feed-bar connected to the clutch, a cam, a pivoted bar bearing against the cam for operating the clutch, and gage-plates for forming the plaits, and means whereby the revolution of the cam causes intermittent engagement of the clutch with the shaft, substantially as specified.

3. The combination, in a plaiting-maehine, of a work-shaft, a clutch mounted thereon, a feed-bar and looper connected to the clutch, a spring surrounding the clutch, aearn revolved by gearing from the work-shaft, a pivoted bar for transmitting motion from the cam to the clutch, and gage-plates for forming the plaits, substantially as specified.

4. The combination, in a plaiting-machine, of the following elements: gage-plates operated from a shaft connected to a cam, a workshaft carrying a clutch, an intermediate pivoted rod, a looper connected to the clutch, and V a pair of earns connected to the ch11 oh and operating a slide carrying the feed-bar, substantially as specified.
