PLAITING-MACHINE.

Application tiled December 2i), 1581.

To aZ whom it may concern.-

Be it known that I, HARRISON G. Oris, a citizen of the United States, residing' in the city of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Plaiting Machines, fully described and represented in the following specification and accompanying drawings, forming a part of the same.

This invention relates to a mechanism for producing a plaited trimming having one or both edges irregular in form, as curvilinear or other shaped patterns, the same being accomplished by a peculiar feeding operation, which consists in moving the material laterally,tirst,in one direction and then in the other, as the plaiting progresses, whereby the edges ot' the material are caused to assume an irregular contour or outline, the exact form of which is determined by the amount and abruptness of the lateral movement of the material. One example of such product is shown in` Fig. 7 of the drawings, and will be more specifically referred to in the course of this specification.

The invent-ion consists in peculiar feeding devices and their combinations with the plaiting mechanisms, together with constructions of parts hereinafter specifically set forth.

A machine embodying the invention is'illus` trated in Figure 1 by a rear elevation, in Fig. 2 by a plan view, and iu Fig. 3 by a longitudinal sectional elevation. Fig. 4 is a sec' tional elevation illustrating upon an enlarged scale the plaiting and feed-controlling devices. Fig. 5 is a plan view of the feed-plate, of which Fig. 6 is a cross-sectional elevation on the line a of Fig. 5. Fig. 7 illustrates a plan View of the product of the machine, the same being a plaited trimming. Fig. 8 is a series of diagrams illustrating several patterns that may be produced by the use of properly-shaped cams for operating the fabric-guide.

In its principal mechanisms the machine shown herein is a common form of plaitingmachine; but in order that the improvements constituting the present invention may be readily understood, a description of the machine will be given at length.

As is common in this class of machines, the plaiting operation is performed by a reciprocating tucking-blade, 2, that folds the fabric between two rotating surfaces. This blade,

however, in addition to its horizontal reciprocation, is vibrated vertically. It is attached to a bar, 4, that is pivoted at opposite ends to arms 5 6, that are hung to swing upon t-he shaft of the cylinder 10. The arm 6 has a project-ing curved rock-arm, 7, which is connected by a rod, 12` through a crank-pin, 29, with a crank-disk, 13, that is mounted upon one end ofthe main shaft 14. One end of this rod 12 is adj ustabl y secured to the rock-arm 7 in a suitable slot by a pivot, 50, and the other end is arranged to be adjustable in a slot in the crank-disk, which arrangements are made for the purpose of varying the horizontal reci procations of the tucking-blade, and thereby regulating the extent of each plate. At the other end of this bar it is provided with a forwardly-projecting arm, 15, that rests upon the curved end of a bell-crank, 16, which crank is suitably rocked by a cam, 17. on the main shaft.

14. During each rearward movement of the tucking-blade it is raised by this bell-crank, so as to clear it from the fabric, and prevent its dragging over the same to distort the newlylaid plait. As the tucking-blade moves forward, it is drawn down to engage the fabric by means of a spring, 8, the low part of the cam 17 permitting its action to produce that etfect. The fabric, whether of tarlatan, lisse, or other material, is led over a table, 31, passed beneath the tucking-blade, and entered into the nip of the pressing-roller 11 and cylinder 10. As here constructed,the cylinder 10, provided with the usual heating devices, as a gas-pipe, 18, is arranged to turn loosely in its bearings, and thus be revolved with a step-like movement frictionally imparted by the prcssingroller 11. y

The pressingroller 11 has its shaft mounted in levers 19 20, which are pivoted so as to y permit said roller to be raised away from the cylinder 10 when it is required to introduce ,or remove the goods, as in the plaiting of the ICO inder 10. A proper elastic seat-ing of this roller 11, to permit its yielding so as to'properly press the plaited fabric,vand its nice adjustment for that purpose, is accomplished by means of spring-seated boxes carried by said levers 19 20, that bear upon the upper surface of the shaft of said roller, the pressure of which Springs is regulated by set-screws 48 49.

A proper step-like rotative movement is imparted to the roller ll, to cause it to appropriately feed forward the plaited fabric by means of a 'ratchet-wheel, 25, mounted upon its shaft, with which ratchet-wheel engages a dog, 9, that is pivoted to a crank, 26, that swings freely on the shaft ofthe roller,and which is properly rocked by aconnectng-rod, 27, to which motion is imparted from the drivingwheel 28 through a crank-pin, 30, attached to a block which is adjustable in a dovetail groove in the face of said wheel. It is also to be remarked that the pin 29, before referred to, is

provided with the same means for adj ustingits position upon the disk 13. This driving-wheel 28, which is a band-wheel, is mounted upon the lnain shaft 14, which it rotates.

By suitably adjusting the crank-pins 29 30, the throw of the tucking-blade 2 and the feed of the roller 11 will be madetosuit therdimensions of the plaiting desired to be accomplished, and t-lie material fed between the roller 11 and the cylinder 1() will be plaited with a succession of folds that will produce the well-known plaited goods, said plaits being retained in position by the ironing action due to thepressure between the roller and cylinder and the heating ofthe latter, or by means of a cemented the upper surface of the fabric and keep the same smooth as it is fed onward, springs S affording the desirable elastic pressure. This guide-plate is adjustable with respect to the cylinder 10 by means of a set-screw, 35. In this improvement the table 3l, instead of being stationary, is rendered capable of lateral movement, carrying with it the fabricguide, consisting of the plates 32 33 34, the table being for this purpose attached by arms 36 37 to a shaft, 38, that slides in bearings in the frame-work, and which is extended at 011e side, where it is connected by a rod, 39, with a pivot, 40, that is adj ustably secured in a crank-disk, 4l, at the upper end of the shaft 42, which is slowly turned by means of a wheel, 43, and worm 44, the latter being at the end of a shaft, 45, that receives motion through wheels 46 47 from the main shaft 14. This crank-disk 41 imparts to the fabric guide a lateral movement, first in one direction and then in the other,

which gives such a feed to the fabric as will produce a plaited trimming the edges of which are scalloped or regularly curved, as shown in Fig. 7, the degree of curvature being regulated by the extent of throw imparted toy said guide bythe adjustment of the pivot 40 (more or less) from the center of the disk 41. It is apparent, however, that this disk 4l performs, broadly, the function of a cam properly reciprocating the fabric-guide in a lateral direction, and therefore that a properly-shaped cam might be substituted for said disk, said cam being of a pattern to produce a zigzag pattern in right IOO lines, said right lines uniting at more or less acute or obtuse angles, or at approximately right angles, thus producing angular points at cord or other fastening applied at the time of the edge of the plaitedy fabric, or alternate io5 the formation, or both. quadrangular projections and depressions.

4o lt ismanifestthat the goods drawn regularly This variation of pattern at the edge Aof the onward over the table 31 will be laid in plaits fabric may be made up of rightlines and curved and produce a trimming with even or parallel lines, according to the pattern of the cam, as edges, and this is the common mode of prowill be readily apparent, all as indicated in iro cedure. Fig. 8. A pattern-cam, therefore, is to be 45 In order that the shape of the edges of the taken as the equivalent of the crank-disk 41, finished trimming may bc rendered fanciful or whether said cam be mounted upon the shaft highly ornamental as the same is produced, I 42, or be attached to the shaft ot' the ratchethave provided the machine with a laterallywheel 25 or to the main shaft. In the .lat-ter 115 reciprocating guide which is automatically opinstance the form of its face would be appro- 5o erated to shift the position of the fabric as the priate to that of the pattern desired, and said plaiting progresses, and thereby accomplish cam would operate to appropriately throw the the laying of the succeedi ng plaits in such manfeed-guide in one direction, the opposite or rener as to produce curved or other shaped bortracting movement being accomplished by a 12o ders or edges, which, by the proper movement spring which is the equivalent of the outside 5 5 of said guide, may have curved forms, as scalwall of a pattern or slotted cam.

It article; but by setting the guide at any other consists of a base-plate, 32, to the upper side angle with respect to the axis of the tueking- 13o of which is secured a bridge-plate, 33, which together form a slotted guide, as in Fig. 6. The forward portion, 34, of the bridge-plate blade the plaits'will be-laid at other angles with respect to the longitudinal center of the material, thus multiplying the varieties that l 33 is hinged to the latter, so as to drag upon may be produced by this invention.

In Fig. 7 the fabric is shown as having its opposite edges alike in form. This of course will result from the production ofthe pattern at one edge.

It is contemplated in practice, whether the fabric have its edges doubled or not, to forni a hem, either to fold the fabric in its longitudinal center to form a doubled patterned edge, or to divide the same longitudinally and form two narrow fabrics, each having a patterned edge. None of the products, however, are claimed in this application.

By the use of this invention the most elaborate articles of ladies7 dress-trimming are capable of production without enhancing the cost of their production beyond that of the most common trimmings made from lisse and tarlatan and similar light fabrics.

The improved trimming herein described is not herein claimed, but forms the subject-matter of another application for Letters Patent iiled by me on December 530, 1881, No. 409,036.

That is claimed isl.
