IMPRoyEpM ENT IN' SEWING-MACHINES.

Be it known that LGEORGE B. ARNOLD,

. of New York eity,have invented a newk and useful Improvement in a Machine for Making Rules; and I do hereby declare the following to be a full' and correct description of the same, reference being had to the accompanying drawings. l

The object ofnny improvement is twofold: first, to make aregular ruie; second, to fasten the ruffle thus made by stitching it before it leaves the machine, wherebyit will be finished for use.

It is desirable that a rutile, whetheniiiade by hand or machinery, should be regular and uniform, inasmuch as it is -to be yused as an ornament, and its beauty depends, among other things, upon these qualities; and therefore any ma-chine which will not make such a ruiile is practically valueless as a rulingmachine.

A machine has heretofore been invented which is designed as a machine for stretching or puckering cloth, and sewing it while so stretched or puckercd. j

I have invented a machine containing the true principles for the production of a regular and uniform ruffle, and have made the same practically successful and valuable to the public.

Une way in which ruiiles are made by hand is that thc Operator with one hand folds a certain denite quantity' Of the cloth, and passes the fold thus made to theother hand, which holds the cloth down upon the table, while the iblding-hand again returns and takes up another port-ion of the cloth, as nearly equal as the skill of the operator will allow, and brings that new portion forward in the shape of a fold to the holding-hand, which, by its pressure, creases the cloth and gives it a set, which' is to be afterward secured by sewing or some other means. In this operation the hand which makes the fold must bring it within reach of theholding-hand, in order to secure the fold that has been made.

An imp roved hand-tool was made by Welcome Whittakerl to aid in the forming of folds, forlwhich improvement he obtained Letters Patent on the 14th of November, 1848.

These operations, thus performed impenfectly Y in section, lookin g from above.-

I Specification forming part of Letters Patent No. 28,139, dated May 8, 1860; extended seven years; Reissue N o.

- v 6,159, dated December 1, 1874 lapplication filed July 22, 1874.

scribed by bringing the'fold which is made by the folding part of the mechanism up to a feeder, which seizes the fold, and which also v passes it on through the machine to make roonffor a succeeding fold. My improved machine also sews the fold thus made before it leaves the machine. .y

The machine on which I exhibit one form of this invention is shown in the accompany ing drawing, in whieh- Figure 1 represents a sectional elevation of the machine. Fig. 2 represents a plan, partly sents a vertical section through the machine in `the line of the drivingshaft, and through the center of it;

In each figure similar letters represent similar parts.

The frame of the machine and the sewing apparatus connected therewith are similar to,

and, in' fact, are4 made from, the well known form ofthe Willcox 8a Gibbs sewing-machine, to which the other parts are added, 'together constituting my invention. y

A is the main frame of the machine. C is the revolving shaft of the machine, which is driven by thewelLknown means. 0n the inner end of this shaft is the eccentric pin X, which imparts the reciprocating movement to the devices employed in ruling and feeding the cloth. The hook for looping`the thread for sewing is at the end of the pin, but is not shown in the drawing, vbeing awell-known device forthat purpose.

E is therecipr'ocating feed-bar' of the ordinary sewing-machine, to which the roughened surface J is attached, passing through the table of the machine l. -This bar E is forked or4 slotted at its outward end, and is mounted u on a pin, H, :which is xed in the frame of-t e machine for that purpose, and which is straddledby theforked end of the bar E. 'Between the jaws of this forked end is mounted an eccentric cani, M, provided with, a handle for the purpose of adjusting itspost,

tion and regulating thethrow of the feeding apparatus. This cam rests against the in H when 4the feeding-bar E -is at the ext eme Fig. 3 reprelimit of 4its movement to the right, as the drawing appears to the observer; and it is apparent that as this cam is adjusted it will ing if its motion were not arrested f, by thel cam M.

The inner en d of this feeding-bar is also provided with a slot, which straddles the eccentric pin F, which is screwed into the bar B. This pin F, by being turned on its axis with a screwdriver, will slightly raise or lowerthe feed bar E, so as to change the position ofthe roughened surface J relatively to the bar B. The bar B receives motion from the revolving shaft C, and communicates motion to the ruiiiin g apratus and to the feeding apparatus. This bar B is parallel to the feed-bar E, and at its outer end is provided with an open fork, by which it is mounted on and supported by the pin H. A spring, Z, arranged in a manner similar to the spring Y in the feed-bar E, tends to move the bar B away from the pin H, and to press it against the revolving eccentric pin X at'the point of contact 0, which pin X passes through a long slot in the bar B, whose width vertically is no greater than the diameter of the pin X, but whose length is `at least as great as the length of the eccentric movement of that pin. When. the shaft C revolves, the 'spring Z presses the bai' B against the pin X at the point O, and, if Jrhere is nothing to prevent it,

r-thebar B would follow the eccentric pin X in 'contact with it to -the extreme end of its movement. To regula-te, however, the extent of the movement of the bar B, the cam L is centered -tothe frame of the machine in such a position 'that the bar B will come in contact with its eccentric edge sooner vor later, according to the position of the cam L, and when it does come in contact with this cam it cannot follow the eccentric pin X, and thus the length of its throw is limited.

Attached to this bar B is a roughened-surface feeding apparatus, G, which passes through the plate I of the machine in a manner similar to the ordinary roughened-surface feed.

ln the bar Bris a pin, D,Iso fixed that it will comeinto contact with the end of the bar E `|u st in time to prevent the roughened surface G from coming into contactwith the roughened surface J. As the shaft U revolves and carries the eccentric pin X away from the position shown in the drawing, the lbar B follows the eccentric` pin, and the bar E'follows the bar B, both being driven in that direction by their respective springs. lf the cam M is set so as 'to 'limit `the travel of the bar the barE will be arrested before the barB has ceased to move,'and the bar B vwill continue to follow the eccentric IpinX either 'to the "end of its movement,or so far as maybe desired fonthe purpose of forming a fold, which distance will be determined'by the set of vthecam L. As the shaft C continues to revolve the movements will be reversed-that is to say, the rufiling-bar B will be first moved toward the bar E -until the pin l) comes into contact with it,

after ywhich the two bars will move together till the eccentric pin X has made its full stroke. By varying the adjustment of the cams M and L, the relative kmovements of the ruffling and feeding apparatus may be varied indefinitely, and any sized folds may be formed within the limits of the movements of the mechanism as constructed in any particular ease.

N is theneedle-bar, carrying ,a needle for the purpose of sewing down the rutile when made.

Operation: Thecloth to be ruffled is placed in the machine, and the cloth will then be pressed down upon the two roughened surfaces J and G, the effect of which must be to fold that portion of the cloth whiclrlies between the rufiler G and the feeder J, because the feeder J holds fast the cloth at a point in advance of the portion which is to be folded, and the ruffler G advances upon that point,

doubled upon itself into a fold.

fore it leaves the machine; and these operations are performed in the 'followingmannem The ruffler G with the fold just formed, having overtaken the feeder J, continues its'movements, taking withv it the feeder J, and carrying the fold to where lthe feeder J traverses, and where'it can be caught by the feeder J in its succeeding movement. In this position the fold is left unde'r pressure, and the ruftler G and feeder J, by sinking, release their hold upon the ruffle, and retreat for a new operation. As the shaft revolves the feeder J retreats as far as the length of made ruffle which the machine is to deliver at each stroke of the feeder, which is determined by the set of the cam M, and the ruffier G retreats as much farther than the feeder J as the length of cloth which is required to be folded in the manner already described into the particular kind of ruffle to be made; and so thisadditional distance which the ruffler G retreats 'bev comes the measure of the fold to be formed, And thus the operation is repeated, a new fold being formed by the rufder G, and by it brought into the gripe of the feeder J, and a presser-foot of a sewing-machine.

ruffler G is adjusted by the use of the 'cam L,

vand it is obvious that 'essentially the to be formed, and the ruiler G i kinds of sewing-machines cloth is at rest, in the manner well known for sewing any fabric which is passing under the When it is desired to vary the length of the fold, the

so as to have a longer or shorter movement; the Width ofthe fold may be indefinitely increased by increasing the length of this stroke of the ruiiler G; and, in order to preservel the desirable pressure upon the cloth, the eccentric pin` F Ina be turned' with a screw-driver, the effect of w ich will be to raise or lower the level of the surface of the feeder J relatively to the level of the surface of the ruier G. It.must be evidentnow that my machine forms a ruffle in same way as I have said it was 'and brings it up v'the ruer While sometimes formed by hand-#that is to say, the

rulerG forms'the fold by the assistance of the feeder J, which holds the material in ad vance'of theruiiler G at a denite distance,

whichI distance measures the length of the fold also lelivers the fold thus formed to the feeder J, which presses it and passes it out of themachine.

-I do not limit myself. to the special devices for ruflinggor feeding which are exhibited in my machine, as these devices are simply equivf alents of analogous devices, which have been used in sewing-machines for the purpose of feeding the cloth in these machines neither do I claim two distinct feed-wheels having a differential motion, for this is already pateuted.'

It is also apparent that any of the various may be used ib secure the-rudio formed by means of thecombtv nation described, and that, if no needleis used at all, the machine will fold and deliver a creased ruffle, which lmay subsequently be sewed, it' desired.- V

What I claim as my invention, and desire to secure by .Letters Patent, is. v

1. A machine composedof a ruiller and a feeder, in which the ruier folds'the 'cloth to be ruiiled and brings the fold up to the feeder, and the feeder holds the cloth, as described, in advance of the ruiiler 1while the foldis being the relative movements of the ruffler and feeder measure the width of foldto he formed,and in "which the ramer iblds the cloth to be ruled l tothe feeder, and the feeder holds-the "cloth, as described, in advance of the fold is being made, and through the manner set afterward feeds the formed ruile machine, all substantially in the forth.

. 3. A machine composed of a ruiiier. and a feeder, substantially as described, in which the relative movements of the ruier and feeder measure the width'of the fold to be formed, and in which the ruier folds the cloth to be ruffled and brings it up to the feeder holds the cloth, as described, in' advance of the ruflier while the fold is being made, and afterward feeds the formed rutile through the machine, in combination with a sewing .mechanism, substantially asset forth. i
