Application filed June 16, 1909. Serial No. 502,529.

To alt teh-om. it may concern:

Bc it known that I, Emi. Kitnx'znin, a

citizen ot' the German Empire, residing at Barmen, in the Province oi Rhenish Irussia and Kingdom ot Prussia, Germany,have invented certain new and Vuseful Improvements in Single-Threaded Lace-Bobbio Maa few plates and never on two neighboring 'plates are driven by continuously rotating drivers engaging ,with their driving wheels.. Consequently in the case ot these machines 4special contrivaiices are necessary for the purpose ot' teiul'ioi'arily stopping the bob-l bins and said ontrivances not only make the whole construction of the machines very Complicated but frequently they do not work reliably.

In contradistinction to these welt-known iachines lthe essence of the new bobbin-machines made according to the present' invention consists in the bobbin-t'lrivers being moved through suitable intermediate members by the jacquard machine and never heing` set in action unless the bobbins, which are situated on the corresponding plate, are to work, that is, are to revolve on said plate or to be transferred to the neighboring plate. In the Vcase ot' this ne f arrangement ot the machines, the stopping devices for the' bobbins are consequently no longer necessary and the continuously rotating toothed wheels which drive the drivers and which have hitherto existed in the case of allV bobbin-machines are dispensed with. quently the whole construction of the inachine is very much simpler tha-n that of the old machines, and moreover the new machine runs more quickly and with greater.

bin-drivers v,so that a special track and the arrangement of tongue-switches is no longer requisite, the plates being arranged Conse- I revolubly withv a tight tit in the track-plate and regulating the motion of the bobbi'ns. In the case of the new machine. in consequence ot the avoidance ot' vthe opentra'ek, the penetration ot dirt into" the interior of the machine is likewise avoided'.

In the acc mpanying drawings one embodiment of the invention is illustrated by way of example. A

In said drawings Figure l is a part sectional elevation of a part of' theA machine, Fig. 2 a plan of the saine, Fig. 3 a se'ct'ion on the line A-A Fig. l, andv Fig.` 4F' a' sec'- tion on the line B-B of Fig.` l in whichffor the sake oi simplicity the plates' are drawn asy though situated in a straight line. I 5 is a diagrammatic pian of the machine, some parts heine' removed, Fig. 6 al section' on the line C-C Fig. 5, and Fig. Tali elevation ot a detail.

Referring to the drawings. l is the lower plate and 2 the upper plate on which the bobbins 3 move. and inwhich the driveis'l are arranged. These drivers Aare of course arranged as usual in a circle and as sl'iowii `diagrammatically in Fig. 5. In Figs. 1 4 however, they are drawn as though they for the sake of simplicity. 'Ihesedrivcrs si, are circular and each possesses two drivingr recesses o situated 180 apart, in'whi'clrthe bolobins 3 are held with their circular core The drivers t are secured onspindles 7 which arc rcvolubly guided in VA bushes 8 fastened on the lower plate l, so ltliativith the aid of these spindles 7 the drivers 4. 'can be rotated in the upper plate 2 inl which they are accurately fitted'. In their position of rest the drivers occupy the position indicated at the right of Fig.-v 2', that is',

neighboring plate that'eacli oftwo'adjzicent drivers can carry valong-with .it the. hobh'm designedthat each plate can be rotated ving drivers are ata standstill, whichl sutticlent since as mentioned above in the were situated inta strai'i'ht lino. this bein'g'- in such a position that the re'ccsseso oi'two neighboring drivers correspond withvv one. another and consequently' form acominon opening` in which pa bobbin 3' is situated. Fach driver so movesintothe patli 'oft-lief situated between them,y and `thus a bobbin can, as desired,be left onthegsame driver orbe -traiis-tened on to the next one `accord`` ing as. the one or the other plate is rotated.v The driving recesses are consequently so without hindraiice-wliile the two nei'gliborftcf, uch :are

.C :ture und considcnhiv 'nu' the In order to secure the bobiin-drvcrs H nit Csm" rectly with the beater-needle As soon as the rack is displaced by the jacquard ma'- ehine the bobbin-driver is rotated, and the beater-needle moves away from the place ot interlacing. whereas as soon as the rack has returned under the action of the spring l) into its starting position said striker-needle dies forward again and strikes against the crcssingotl the threads which has just been produced.

IVhat I claim as my invention and desire to secure by Letters Patent is:-

l. In combination with a series of drivers and their spindles, the bobbins carried by said drivers. pinions turning with the spindles ot said drivers. racks engaging said pinions. means for reciprocating said racks and means for removing the pinions from engagement with the racks during the return reciprocation of the same, for the purpose set forth. .l

Q. In combination with a series otl rotary drivers, the bobbins carried by them, the spindles ot' said drivers. pinions turning with the spindles ot' said drivers, reciprocating racks adapted to engage said pinions. rings carried by said spindles and having laterally attened parts. and devices spring pressed against said rings to prevent by engagement with the flattened parts the bebbin drivers from turning by their centrifugal momentum.

In combination with a series of rotary drivers, the bobbins carried byr them, spindles for said drivers, pinions, attened rings carried by their respective spindles, pressers spring held against said rings, reciprocating racks engaging said pinions and stops attached to said racks and arranged to co- ,operate with said springs in holding said pressers to their work at the end of the longitudinal movement 'of each rack in one direction substantially as set forth.

L In combination with a bobbin driver and means for rotating the same, a bobbin carried by said driver, its pin, a fixed part of the machine, a guide plate on said bobbin pin and a spring forcing said guide plate against said iixed part to act as a brake substantially as set forth.

5. In combination with a bobbin driver and a pinion turning therewith, a rack engaging said pinion, means reciprocating said rack rack-and said needle whereby. the .former operates the latter as its action is needed in interlacing substantially as' set forth.

G. In combination with levers arranged to be actuated by jacquard mechanism; angle levers andtconnecting rods actuated by the levers first mentioned. racks reciprocated by said angle levers, driver spindles provided with pinions which are fast thereon and engage Said racks, drivers rotated thereby and pairs of bobbins carried by said drivers as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses. j
