This invention relates to a multiple bar In place ofth e ordinary bar which usually attachment for lace machines and has for an extends between the lace machine and the object to provide a connection between the jacquardand whichis operated throughthe lace machine and the jacquard adapted to usual dropper boxes carried by the jacquard 3 control the operationaof'the machine whereby for working the machinethe usual number to permit an increase in the number of gaits ofgaits, I provide a flexible bar l3having one possible to be worked by the acquard. end extending in a direction toward the lace A further object is to provide an attachmachine 6 and arranged in operative assoment of this character which may be interciationtherewith in a manner well understood o posed in operative position between a levers in the art, and its opposite end wound about 60 lace machine and the conventional type of the drum 11 and secured thereto. Aworking jacquard employed in connection therewith, arm 15 is connected to one of the dropper without necessitating any changes in the conboxes on the jacquard and operated by the struction of either the machine or the jacdropper in the same manneras theordinary i quard, which is simple and practical in conbar as heretofore provided. The; opposite (1;) struction, efficient and reliable in performend of the arm is provided witha setof ance, inexpensive to manufacture and install teeth 16 inthe form of a rack bar and en and otherwise well adapted for the purposes gageable with the teeth of the cog-wheel 12 c for which the same is intended. whereby through the operation of the armlo I Other objects and advantages reside in the the cog-wheel 12 isrotated so as-to move the To special construction, combination and arbar-13. r u I u rangement of the various elements forming After the arm 15.has been operated to its the invention asmore fully hereinafter de-' fullest extent, the cog-wheel is'secured bya scribed and claimed, reference being had to stop17 which is'also connected at one end to 2 the accompanying drawings forming part a dropper box on thejacquard with its op- J5 hereof, wherein like numerals refer to lille posite'end provided with a rack segment 18 parts throughout the specificationsand 1n for engaging the cog wheel and securing the which same against movement The stop 17 issup- Figurel is a top plan view of my attachported on the shaft 10 through a slotted openso ment shown in operative position with re ing 19 so that upon the operation oflthe stop c.-

The cog-Wheel is thus held until the release rod 20 also operated through one of the dropper boxes has been moved to move the arm 15 from engagement with the cog-Wheel, the spring 2% returning the arm 15 to its original position. The release rod 20 is then released from the jacquard to be returned to its original position by the spring 24 attached thereto which thereby moves the arm 15 into engaged position With the cog Wheel. After the jacquard has released the stop 17 Which is returned to its neutral position by the spring 2 l the attachment is then ready to repeat the operation ior'working an v additional 31 gaits.

It is obvious that the invention is susceptible of various changes and modifications Without departing from the spirit of the same or the scope of the appended claims, and l accordingly claim all such forms of the invention to Which I am entitled.

I claim:

1. A control attachment interposed be tween a lace machine and its operating jacquard comprising a flexible bar, operating means therefor, means releasably retaining bar and means attached to the jacquard for periodically releasing said bar retaining means. a

2. In a control attachment interposed between a lace machine and its operating jacquard comprising an operating har extending from the acquard and operated thereby to the machine, a drum having one end of the bar secured thereto, a cog-Wheel attached to the drum and arranged for rotation there with, a working arm opera-tively connected to the jacquard of the machine, a stop, a release rod, said stop and said release rod being o'peratively connected to the jacquard, means for engaging said stop With the cog-Wheel and means associated With the release rod for controlling the engagement or disengagelnent of the Working arm and stop With the cog-Wheel.

In testimony whereof I aflix my signature.

LOUIS DEBAENE.
