ERNEST JARDINE AND JOHN ARCHER, OF NOTTINGHAM, ENGLAND.
BRAIDING-MACHINE FOR MAKING BRAIDED AND PLAITED LACE.
Application filed July 8, 1912. Serial No. 708,301.
7 '0 all whom it may concern I Be it known that we, Ennnsr J ARDINE and JOHN ARCHER, subjects of the King of Great Britain, and residents of Nottingham, in England, have invented a certain new and useful Improvement in Braiding-Machines for Making Braided and Plaited Lace, of which the following is a specification.
This invention relates to braiding machines for making braided or plaited lace, and refers more particularly to improved means for actuating and controlling the movements of the thread bobbins.
Referring to the drawings, Figure 1. is a plan, and Fig. 2. a sectional elevation showing a machine constructed according to our invention. Fig. 3. is a plan of a segment of the machine. Fig. 4. is a corresponding view, showing a structural modification. Fig. 5. is a cross section of the modification shown in Fig. 4. Fig. 6. is a plan, and Fig.
7. a cross section, showing a double acting arrangement. Fig. 8. is a view showing the course of the threads in ordinary working. Fig. 9. is a view illustrating the result which is obtainable with the double acting arrange ment. Figs. 3. to 7. inclusive are drawn to a larger scale than Figs. 1. and 2.
Like letters indicate like parts throughout the drawings.
According to the present invention, two races are provided for the bobbin carriers 1 to travel along, that is, one inner race 2 (see Figs. 1. and 3.) and one outer race 3. These two races approach each other at regular intervals, and are at these points connected by communicating spaces 4, so that the bobbin carriers 1, can be transferred from one main race to the'other, as required.
The two races described, are formed by means of a series of small plates 5, preferably of an approximately oval shape, disposed between the scallop shaped edges of outer and inner race rings 6 and 7, which latter form in conjunction with the above mentioned series of small plates 5, the said inner and outer races 2 and3, with communicating spaces 4. As shown in the drawings (see Fig. 2.) there are upper and lower race plates 5, and race rings 6 and 7, so as to provide support at two points for the bobbin carriers 1. The whole of the race plates and race rings described, are carried by pillars 8 attached to the machine bed 14," the upper and lower series of plates '5, being preferably adjusted level with the Specification of Letters Patent.
" Patented m *7, 19,14.
upper and lowerrace rings 6 and 7 respectively, as shown.
The bobbin carriers or spindles 1 travel in.
the races 2 and 3described, and'in order to transfer them from point to point, and cause them to interlace or twist their respective threads together, the following arrangement is employed in place of the usual rotating drivers, for'which' the series of small fixed oval plates opreviously described, are substituted in the present arrangement.
In connection with the inner race 2, is an inner driving ring 9, provided with gaps or notches 10 (see Fig.3.) on 1ts outer edge,
said notches being the same distance apart as the communicating spaces 4, which connect the inner and outer races 2 and 3. Thls ring 9 is situated between the upper and lower inner race rings 7, and is reciprocated,
by suitable means, through a space equal to or in excess of the distance between one'or.
more of the communicating spaces 4. In connection with the outer race 3, is a second outer annular driving ring 11., which is situated between the upper and lower outer race rings 6 and reciprocated in asimilar manner to the inner driving ring 9, but in the reverse direction, In this case gaps or notches 12, (see Fig. 3.) are cut in its inner edge, corresponding to the notches 10in the inner driving ring 9. .Suflicient space is provided between the outer edge of the inner driving ring 9 and the inner edge of the outer one 11, to permit of the bobbin'carriers 1 coming to rest, and remaining so, when they are moved into the middle of the communicatng spaces 4. The normal position of the said bobbin carriers 1 is in the communieating spaces4, where they are at rest as previously described, and in order to set them in motion, they are moved out of said races, by means actuated by cam or jacquard mechanism. into one or the other of the races 2 or. 3. This movement carries them into the gaps or notches, 1n one or the other dr1vmg rings 9 or 11 as required, when they are carried along the races 2 and 3by the said driving rings to the next communicating time said rings areabout tomov'e in the required direction.
When moved out of the communicating spaces 4 into the mam races 2 or 3, as de scribed, and then carried along the latter by the driving rings 9 and 11, the bobbin carriers 1 are automatically returned into the communicating spaces 4 as previously de-v scribed, by means of spring actuated arms,
slides,-or-other suitable means, such devices being provided for this purpose at'eac-h of the communicating spaces 4. These devices act on, the bobbin carriers 1, and'move them intoth'e middle of the communicating spaces '4', and they are checked'in theco-rrect position by suitable stops, and are thus held out of "engagement with both, driving rings 9 and 11. This takes place every" movement,
thus bringing them all to rest, so that a fresh selection can be made, and. the selected communicating spaces 4, by means of slides, levers, or other su1table devices, connected bobbin carriers'l be set in motion again.
The bobbin carriers 1 are moved out of the toa'nd actuated by cam or jacquard mechanism. 25
As shown in Fig. 3. radial slides 13, are provided in connection with each communicating.space-4,,formoving the bobbin car riers 1 out of said space into the main races.
These slides are mounted on the bed14, and are formed with a space to admit thelower end of the bobbin carrier-s 1, so that when moved radially they move the bobbin carriersout of the communicating spaces'4 intothe main races 2 or 3 as required. The device for automatically returning the bobbin carriers into the communicating spaces 4, may comprise'levers 15, which are pivoted upon and'form part of thebeforementioned slides 13, said levers being connected to and actuated by'springs 16,,which also serve to connect the slides 13 to the bed 14, and re turn them to their normal. position again.
" The bobbin carriers 1 are returned to the proper position in the spaces 4, by means of said levers 15 and parts 17 on the respective slides 13, the former of which will engage with the lower ends of the bobbin carriers 1,
and by the action of the spring 16 push it' inward,while the part 17 acts as a stop.
The-inner driving ring 9 may be actuated by means of a lever 18 (see Figs. 1. and 2.)
whichris pivoted on the central'pillar '50 of the machine, while its two outer ends 19 are secured to the driving ring 9/ The lever described is actuated by means of a crank, cam, or the like acting on or connected to an intermediate point in the length of the lever 18. Asshownin the drawings, a crank pin 20 on a disk 21'on a vertical shaft22, (see Fig. 2.) engages in a bearing block 23 "(see sliding in a slot 24 in the lever 18.
The outer driving ring ll may be actuated by connecting it'to the outer end 19 of the lever 18,by meansiof rack p'inion-mechanism, or as shown in Fig.1. by a 11:11:25,
lever 26 pivoted to the bed 14, and a second link27.
In'the modification shown in Figs. 4. and 5. the driving rings 9 and 11 are provided with projections 45 with a wide space he tween. The inner ring 9 has its projections 45 so disposed, and it is reciprocated through such a. limited angular space, that it will only act on the bobbin carriers 1, in every alternate commumcatmg space 4. The outer drlving ring ll'has its pro ections 45 so d1sposed that it will only act on the bobbin carriers 1, in the remaining communicating spaces'4. In this system of working it is not necessary to push the bobbin carriers 1 into the middle of the communicating spaces 4, but they may 'be left at the entranceto the same as shown in'Fig. 4. as wherever a bobbin carrier 1 is left by one driving ring, it there remainsuntil itis pushed over into the other race, and into the path of one of the projections 45 on the other driving ring.
I The radial slides 13 for moving the bobbin carriers 1 from one race to the other, are
in this arrangement only adapted to receive the ends of the bobbin carriers 1 as shown in Fig. 5. the use of the spring actuated pivoted lever 15, being in this case obviated. Ii des rable spring actuated buffers 46 .(see Fig. 5.')'which work in vertical openings in the bed 14 may be employed toengagewith the lower end of the bobbin carto prevent accidental disthis case the saiddevices or slides 13 are actuated as usual in pairs by means of levers 28. (see Fig. 3.) carried .on the upper ends of shafts 29 mounted in bearings secured to the bed 14. The lower ends of these shafts are provided with arms 30 (see Fig. 2.) which are connected to the jacquard in the I usual manner. The. particular construction described however permits of the use of what may be termed a double actuating are rangement, in. which two devices are provided at each communicating space 4, for returning the bobbin carriers 1 into the said communicating spaces 4, that is, one on the outer side for returning them from the outer main race 3, and one on the inner side for returningthem from the inner race 2, and provision is made tor removing either one or the other of said devicesout of the way, at the same timethe. bohbincarriers 1 are moved-out of the communicating races 4, into the inner or outer races 2 or 3. A greater diversity of movements can thus be obtained, than with the single acting arrangement. An arrangement of this description is shown in Figs.' 6. and 7. In this case the driving rings 9 and 11 are pro vided with'radial ins 32 at the point where each gap is formed, the said pins beingsituated in holes provided for them in the driving rings themselves. The inner ends of these pins 32 are adapted to act on the bobbin carriers 1, while their outer ends run on fixed cam surfaces 33, fixed on the machine bed 14 between the communicating spaces a, and movable noses 34 set opposite to each of the said communicating paces 4. The movable noses 34 are carried on the upper ends of levers 35 (see Fig. 7.) pivoted to brackets 36 on the underside of the bed 14.
In addition to the lever 35 described, there are two jacquard levers 37 and 38 (see Fig. 7.) on the underside of each of the communicating spaces 4, which are adapted to engage with the lower end of the bobbin carriers 1. These jacquard levers are connected to the jacquard, one 38 being disposed so a to move the bobbin carriers 1 into the inner race 2, and the other 37 to move them into the outer race 3. The inner of the two cam levers 35, is connected to the outer jacquard lever 38, by a link 39 having a certain amount of lost motion, and also by a spring 40. The outer cam lever 35 is in like manner connected to the inner jacquardlever 37 by a link 41, and also by a spring 42, and the action of the arrangement is as follows :The pins 32 which are controlled by the cam surfaces 33 and lever actuated noses 34E, always move the bobbin carriers 1 into the middle of the communicating spaces 4, and they can then be moved either back again into the same race they have just left, or moved across in the other race. This movement is effected by the levers 37 or 38 which engage with their lower ends, and whichever way a bobbin carrier 1 is moved, the corresponding nose 34 will be drawn back by the cross lever connections described so as to permit of this action. By means of this double acting arrangement any one or more threads may be passed over or around any number of other threads.
In ordinary single working for example, as shown in Fig. 8. the threads must always intcrlace as they move from one position to another.
As shown in Fig. 9. it will be seen that by meansof the facilities provided by the double acting arrangement, a thread 46 can be carried around a series of other threads, and new effects can thus be obtained.
With the arrangement described, the use of the gear wheels which is necessary for driving the ordinary rotating drivers, is obviated, and the machine runs with less noise and greater steadiness and certainty.
Another great advantage is that by the double acting system a bobbin can be transterred from point to point without twisting its thread with any of the others, and a class of work can thus be produced which has not hitherto been possible on this class of machine. 7
