abs'ingiand. lacamaking machines by temporary stopping off the bobbins in their tracks or at V -'th'epo1nts intersection or crossing of the g same is wel. nown. T

' 1 Ii -order to cause the arrested bobbin to 5 115?again}pass into the track in front of the drivers, slides are used which cause the bobbin to: move from the position of rest until it iaplaced at such a point in the track that it is 7 withinrange of the bobbin drivers.

This, invention" relates to a device for effecting'the stop ing at the oints of inter, section'in a simp e and reliab e manner. To that endthe plates or trays are oval, that is to say longer ln the direc tion of the wheel cir 25. 016, than in their direction of width, and the drivers of the bobbins are of such length that they leave the" driver pin of the bobbin when the latter has arrived at the center in front of 1 the 'ointof intersection or crossing of thetrac so thatthe bobbin stops here in front of two spring stopping devices or holders reaching into the point of'intersection, while it isagain rendered. operative by a slide driven by the pattern gear which forces the bobbin between the two spring holders into the track to such an extent that it arrives ain' in front of the driver. 'As

widene portions or recesses in the tracks or atthe points of intersection are avoided, the bobbinzhas everywhere a positive uidance and is always stop ed again at t e same. point atthe place 0' stopping. As further, the attern gear has no connection with the bob in stop ing devices, but only affects the advance of t e bobbin slides, the machine, in addition to being made to work in a reliable manner, can be considerably simplified and ch'eapened.

In theifdrawings, Figure 1 shows'in plan a, portion of the trackupper plate of the machine, Fig. 2 is a cross-section on line A'B of Fig. 1, and Fig. 3 is a plan in section on line 1 Gel) of Fig. 2. Figs. '4 and'5'are respectively plan and oross-seotionuof a modified construction of the bobbinstopping device.

Fig. 6 shows a bobbin slideand switch-mo tion in plan, on a portion of the machine, the upper plate bein i shown dotted, and the parts arranged un er the bottom plate of theniachine, beingalsoshowndotted. Figs. 7 0b;

and 8 are also plans with the driving devices-s in different ositions. Fig. is a cross-se tion'on line --F of Fig. 6. j Y I The trays a are larger in the direction oft ',the wheel-circle than in width, and the bob- 5;;-

bin drivers I) are of such length that they carry with them the bobbin into the tracks. having the 'shape'corresponding to that ofaw the trays, only up to the center in front of the crossing, and then pass the bobbin pint Be-" 7a; tween the drivers of two adjoin' 'wheels there is, therefore, a distance whic isa proximately equal to the thickness oft e obbin driving pin. Underthe drivers are I mounted on suitable supports 0 spring, holders dwhich face each other withstheir' free ends and form. an inlet angle for the driving pin. f of the bobbin g. The drivers b bring the bobbins up to the angle formed .by

the -holder springs and then pass the bob-- .bin pin. In that position the bobbin can, therefore, be stop ed for any desired length: of time. 7 At each point of intersection on crossing, are mounted; opposite the switches h arranged and moved i: well known manner, that is to say alternately on the inner and outer side of the wheel-circle, slides 'iwhich 'are advanced by the patterngear, and push the bobbin which stopped in front of the holders d, with its front end into the track in front of the drivers. This position of slidesand bobbins is shown in Fig. 1 at 'i, and-f According to the position 0 the switch, the advanced bobbin is brought to the right or to the left into the track and thus caused to f Work. The slide '1', is controlled by a s ring 7c which brings it back again after eac ad: vance by the pattern gear. The connection! of the slige to the pattern gear can be effect ed in di erent ways. illustrated Fig. 2, a bell crank lever m ensgages behind a projection n of the slide i,- against which also presses the spring 70. The other arm of the lever m is connected to'a; second bell crank lever 0 arranged under the 105 machine and driven by means of the connect ing rod p by the pattern gear. I

As the springs d have often to be repaired owing to the wearing out, and are easily broken they can be replaced by a bobbin In the construction proximately at such point.

holder w is co cted to the advance slide and the free end of which, engaging behind;thebobbin pin, is moved, during thei' advance of the slide to such an extent beyond the crossing of the tracks that the advanced. bobbin can'pass the end of the p To the slide i driven by the patterngear,

is secured the bobbin holder or stopping device l igs. 4' and 5 the free end 1" of which is, bent slightly upwards this end, when the slide is pushed back being'situated beneath;

, ,The return of the slide i is effected, like in the preceding construction, by a spring 7c.

At the upper part of Fig. 4,'the slides iandholders 1 r, are shown in' that position in which the bobbin, left by the drivers Z) but still advancing owing to its momentum is held up and stopped by the holder r,. The bottom part of Fig. 4 shows, on the contrary,the slide '5, with theholder r 7-, in advanced position, and it will be seen that in this case the holder has passed so far beyond the crossing of the tracks that the bobbin pin f can freely pass.

In order to guide the bobbin g which has been advanced and carried along by the drivers, either back to the plate from whence it comes or further on to the adjoining plate, the switches h are moved to and fro between the plates in well known manner. For this continuous uniform'os cillationof the switches, there are several wellknown, more or less complicated, driving devices for which a comparatively large consumption of power is required. The parts are also liable to great wear, so that it is frequently necessary to repair the machine or to replace the parts. These drawbacks are greatly reduced by the arrangement shown in Figs. 6 and 9. These arrangements are characterized'l by the simultaneous movement of the slides/which advance the bobbins and the switches by? means of. a system of levers actuated by the pattern or jacquard gear: 2 by the fact that two levers are provided'for moving each slide, each of said levers being separately connected with the jacquard gear. -'Each slide is advanced, simultaneousl with one of the slides next thereto but on t e opposite side of the track, owing to the pull of the jacquard gear. Owing to this :combined switch andslide motion, only those switches are moved in which a change of position is refholder or e produced,, all other switches remaining in" the positionof rest. -The airrount of power consumed is therefore smaller, and the wear of the machine is reduced.

This method of coupling and connection to the pattern gear results in each slide being advanced either together. with the opposite adjoining s lideto the left, or with the adjoining slide to the right, according asthe pressure" levers 1) or w are partly turned by the pattern ear. I f I o The switches h are controlled by springs in such manner that they all press against the same side of the trays a, so that, as shown in Fig. 6, the correspondin track is uite open in one direction of trave of the b0 bins, and

N hen the bobbins travelas shown in Fig. 7, in which,

case the threadwof the bobbins rotating in pairs on the trays continuously produce a braiding strand, it is merely necessary to move the outer switches h, since the track for the bobbins f 7"; f, is open. These outer switches are moved by means of the pressure levers 1) by the connection 1 y, 31,. The inner switches= which are move by means of the pressure levers w by the connection w 66 43 utilize the open track and the movement of the inner switches takes place owing to the advance of the slides by the pressure levers. -w. The outer swit hes and the pressure lever was well as all the levers and the rods, remain therefore in the position of rest. Owing to the last mci'zi'ionel mutual passage of the bobbins, thvir threads form in well the hand bobbin lace is produced.

known manner the connections between the single strands, and a ineshwork peculiar to It will be seen that in this arrangement always only a portion of the switches is moved, so-that the economy of power is the greater, the reater the numberof trays of the machine. t will be also seen that owing to the temporary stopping of the switches and of the parts moving them, the wear is reduced.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A braiding and lace making machine comprising crossin tracksand bobbin drivers, bobbins wit pins, trays of greater imension in the direction of the wheel circle than in that of the width, spring holders for the bpbbin pins constituting an inlet guide and arranged at each crossing to act as a bobbin stopping device, slides independent of one another for moving the bobbins free from the holders into reach of the drivers, and pattern gears for controlling the slides.

2. A braiding and lace making machine comprising crossing tracks and bobbin drivers, bobbins with pins, trays of reater dimension in the direction of the whedi circle than in that of the width, spring holders for the bobbin pins constituting an inlet guide and arranged at each crossing to act as a bobbin stopping device, slides independent of one another for moving the bobbins, pattern gears controlling the slides and bobbin stopping devices secured to the slides.
