Application filed June 10, 1913.

. T all 'w hom it may concern Be it known that I, KARL EGGART, a subject of the Emperor of Germany, residing at Arbon, Switzerland, have invented new and useful Improvements in Jacquard Embroidery-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to Which it appertains to make and use the same, refs ercnce being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

hen in Working with a jacquard embroidery machine it is desired tov change from embroidering to perforating, those de vices Which are used for the embroidery operations, and in particular the needles, have to be thrown out of operation. In all prior machines of this class it has been the practice to stop the main shaft of the machine when perforating, either upon throwing out the needles or subsequently thereto. Among other disadvantages attachin to this method, however, is the difliculty met with in coupling the main shaft of the embroidery machine again in the right angular position relatively to the jacquard shaft, on

the subsequent return to the embroidery work, for it is absolutely essential that the embroidery machine shaft shall start its motion in a certain definite position relatively to the jacquard shaft. In order to overcome this difiiculty by the present invention certain devices requisite in embroidering are thrown out of gear on the change being ma e from embroidering to perforating, but t 18 main shaft of the embroidery machine is hot stopped 'for this purpose. in, this manner clutch mechanism can be altogether dispensed with. A further advantage is that'the perforating-cam can be mounted directly upon-the embroidery machine sha (this being always in motion), so that the usual auxiliary shaft is rendered superfluous, Furthermore Various auxiliary devices of the en lbroidering mechanism instead of having to be disengaged altogether, can simply be given another motion, so that for example the thread guides for drawing off can be actuated from the main shaft of the embroidery machine.

Four forms of construction of the improved mechanism are illustrated in the accompanying drawing, those parts notneces- Specification of Letters Patent.

Figs. 1 3, 1 is the maim shaft of the embroidery machine, Which, depending upon the speed it is to have, can e driven from the shaft 6 by means .of the gears 2, 3 or 4, 5.

Which is longitudinally slidable in a bar 11. The bar is ointed to two cranks 12', mounted on shafts13, to which are secured arms 14,

jointed to rods 15, whereby the needle bars 16 can be moved to and fro. On the shaft 1 there is also fixedly mounted a cam- 17 for operating the minor thread guides, and secured to this cam is a circular disk 18. With the doublecam thus constituted there cooperates a roller 19, which is mounted on a shaft 20, which is longitudinally slidable in a fork 21. This latter is carried by a rod 22, which is pivotally connected to arms 'haft of the minor on the shaft 1 motion to thread guides is also a cam for impa the major thread. guides. ."f'h. circular disk 26 rigidly secured. to it, so as to form a double cam, and with the latter there engages a roller 27, whose shaft 28 is slidable in longitudinal direction in a fork 29, carried by a rod 30 connected to arms 31 on the shaft of the major thread guides 32. There is likewise mounted on the' main shaft 1 a cam 33 for actuating the fabric pressers. This cam cooperates with a roller 3 L, which is mounted in fork 35 Without capability of sliding axially, While the fork itself is carried by a rod 36. The

M cam has a v rod is connected to arms 37 on shafts 38, j

which carry the fabric pres. ers 39.

Also

mounted on the shaft 1 is a grooved cam for the operation of the sl'iuttles. With this cam there engages a roller ll, which is axially slidable on a lever 42 3) which vibrates on a stationary pin 43. This lever 42 is connected by a rod ll with a. bent lever go, which is connected to a rod 46, rigidly connected w'th the shuttle actuators d7. lhc rollcr ll is inoved axially by a pin d8, rig idlfv secured to c lever 19 which osci ates on a pin Q0. To the lever l9 there is connected :rsvxlcin of rods and lovers 51, 52, 53, Til, which is actuated in well. known manner by the jacquard apparatus, in correspomlcuce with the pattern, that the roller --l-1 can be thrown out by means of the jacquard apparatus.

The shaft i has further mounted on it a grooved com 55. with which there cooperutos a roller 56.

In the modification illustrated in Fig. 7 the grooved cam l0 has only one track 80, so that the roller 11 is inerelv advanced into or rctrartcd from the groove. there being no change of motion. The actuation of the rollczsv 56, l-l. is effected simultaneously by thev jncquz'ud apparatus, lever ill, operated h the jacquard apparatus as already set :lorth. being; (IOflIltClQtl by rod 90, bent lever 91 and rod 92. with the lever l9.

In the modification shown in Fig. 8 also thc' grooved. cam l0 possesses but a single track 80. l-lerc the actuation of the roller 41 is effected by the "acquard u iparutus' with the aid of the rod. 7 which operates simultaneously the rod 7%. The lever is formed as a three-armed lever and is connected by a rod 93 with the .lcv r l9. Thus the shuttles are thrown out simultaneously with the. dis engagement of the needles The various devices of the embroidery machine may, in the change being made from embroidering t0 perforating, be thrown in and out, or a, dillcrent motion imparted and "thread 1 guides, with out stoppage of the driving shalt,
