JACQU'ARD APPARATUS FOR EMBROIDERING MACHINES.

Specification of Letters Patent.

To all whom, it may concern:

Be it known that I, Vroron KoBLER, a citizen of the Republic of Switzerland, residin'g at Promenadenstrasse 92, Rorschach, Switzerland, have invented new and useful Improvements in Jacquard Apparatus for Embroide'ring-Machines; and I do hereby declare the following to be a full, clear, and exact'des'cription of the invention, 'such as will enable others skilled in the art-to which it appert-ains to make and use the same.

The jacquard apparatus constructed according to this invention comprises blades which are adapted to be separately dis- I placed. from the. jacquard card and to be combined in groups.

With the device herein described it possible to have a large number of different .combinationsof the relative position of the blades ofdifi'erent groups, andonly a small 3 jacquard card is necessary, For this pur-'; pose -means" controlling the stroke of vthe frame are provided for each group and ar rangedxtransversely to the bladey'the' arrangement beingv such, that if all blades of I a group are disengaged from the jacquard} card, all controlling means belonging to this group are arrested,while if one or several blades-of a group are displaced, according 0 to the. resulting relative -positionofthe;

blades one of 7 said controlling. means is re: leased. ;j r Q Reference isto he had to the acconipanyingfldrawing's in which: Y

Fig. 5 shows diagrammatically one group of'blades in their fundamental'positionand in ten other positions. I indicates the funda- 'mentalposition in which the recesses 13 of the blades are in such relative position that none of the lifters 28can engage-them, that 1s to say none can enter four adjacent recesses. In the position II the blade ajhas been displaced so that the four recesses 13, at the bottom of the figure, are registering -;and the lowermost lifter 28 can enter them and be raised somewhat so that the fork 21 connected-to that lifter engages its pinof the corresponding slide 18.v In the position III the blade 6 has been displaced which allows the-next lifterto be'raisedr Moving the third blade 0' into the -.position IV allows the third' lifter to be raised; moving the blade (I into the position- V allows the fourth lifter ,tO 'be-r'aised. In position-VI- the blades a and b are displacedztogether allowfourth lifter from the top to-beraised. Displacing the blades a and-c together; position IX allows the third .lifter from the topto be raised displacing-the blades 1) andd to gether, posit-ion X allows the second lifter:

from. the top to be raised, and displacing "the blades a and 03 together position XI allows the topmost lifter to be raised. The displacing of the several blades is' effected from the card 31 which in a known manner, is

guided by a lever 32 that is rocked to and r0 by means of-a cam groove disk33 fixed on the shaft 1. totheir normal positions by means of a bar 34 which is operated from the shaft 1 by means of a cam 36 and a rod and bell crank lever 35.

slides 18 are provided .-with racks 38 and 39.

a grooved collar 44, which is engaged by the fork shaped end 45 of a lever 47, which is pivoted on a rod 46. By means of rods 18 and 49, each lever 47 is connected to levers 50 and 5], respectivcl y, which levers are pivoted on the rod 5) and are adapted to be moved by lateral extensions 14 of the blades f when the levers engage recesses in the said extensions, (see the levers 50 in Figs. 2 and 3). When the blades f are so displaced by the card that the extensions lat-engage the The blades are returned levers 50, then, when the blades are moved downward by ,Ineansof the cams 2 through the parts 8, 7, 4, 3,- the pinions 43 are-raised from the position shown in dotted lines in Fig. 2,; and caused to engage the-racks .38.
