MACHINE FOR MAKING'CHTAIN-.GL0TH.
To' .all 'ivlwm 'it concerm' -U Be it -known that I, FRANK BEMENT, a
citizen of the United States, residing at Shrewsburypin the countyfof Worcester and State of Massachusetts, have invented a new and usefulMachi-ne for Making Chain- Cloth, of which the following is a specification. o l
lThis invention relates to a machine especially designed for making chain fabric which'is made up of interlaced metallic circular links or rings but capable of use for making chains and fabric-of other kinds.
rPhe principal object of the invention is to provide eilicient mechanism by means of which such a fabric or chain can be made in a more expeditious and practicable manner than heretofore so as to eliminate hand operations.
` The invention involves mechanical means for holding the, links of the fabric, and
means for making the new links and inten' lacing them with the old ones, and for continuing to support the fabric as it is pro.- duced in the machine, thepoints of support at one end being shiftedso as to permit the new linkst-o be attached.'
. lhsinvention also involves details of conas will be pointed dutV lin the ms. urther objects and advantages of the inappear hereinafter. Reference is to .be had ,to the accompanyingl drawings, in which- Figure 1 is a plan of apor'tion of the machine Aembodying 'this invention; Fig.'2 is l a front elevation of the same; Fig..3 is a plan .of the link forming die and connective partsgfFig. 4 is an elevation of the same; Fig. 5 is a fra mentaryplan on an enlarged scale showlng how the links are made and supported; Fig. 6 is a longitudinal sectional view ofthe same; Eig. 7 1s a diagrammatic view showing the way in which the links yare supported when they are in position shown in Figs. 5 and 6; Fic'. 8 is a simi#y lar view showing .the next position; Fig. 9
is a plan partly in section showing the next step; Fig. 10 is a View similar to 8 showing the parts in the osition next to that shown in Fig.' 9; and `ig. 11 is a diay grainmatic view showing vhow the third rowl of. links are applied.
This yinvention is designed for making chain fabrics, such forexample as are ordi# y Speei'cation vof Letters Patent.
Application :tiled .Tune 29, 1908. Serial No. 440,852.

in which each link of the fabricconsists of more than one convolution of Wire and thev links are intermeshed with each other so vthat a fabric will -be produced capable of standing very hard usa yIn accordance with t e present invention a single length of wire is fed between the feed rolls 10 along a guide 11 to a die which consistsof a curved back die 12`and 'a bend# ing member or pin 13 curved to the same shae and located in contact withthe curved sur ace of the back die. The wire-is fed by the rolls into a helical groove` 130 -in one of the die'members, as the pin 13, and is .pushed forward so as to receive abendatthispoint, and to continue in -t-he form of a circle. On account of the slight slant of thelgroo've 130 the 'link or rin a being formed'will-tend Vto emerge in the orm of a' coil extending along the bending die member or pin 13. This is overcome and the coil' left on the other side of the wire by means of a guard 14 extending into contact with the wire as it comes out of thegroove so asto bring it over to the other side of the entering wire centrar to the natural tendency produced by'zthe le t ghanded -helical groove 130,50 that aV resilient close coil maybe formed. This :located that the advancing end of the wire ard i's sowill come down by the outer side of theincoming wire and continue to coil up adja- :cent to it. Theguide 11 is provided with a shield 15 for keeping the wire in proper .position and guiding it from the die. .This jshield is curved over and receives the wire as :it follows around from the guard. A cutting knife 16 is employed and is so connected' up and operated that it cuts offv .the wire a te r it passes through .the die-in a periodical' manner so that each circular link sha-1l have the same number of convolutions or partsolf convolutions.
The invention as shown herein comprises `means for making a fabric .in which each -link is formed of-a little less than -two com-l plete cenvolutions, but it will be Lunderstood that the cutting mechanism may be caused to operate in anyv periodical time so aste produce anyother number of convolutions on e'ach link or rin The mechanism for operating the cutter 1s not hereinillustrated as that is well understood. inthisl art and -does not form a part of this invention.

The machine is'shown as comprising a bed 17 on'which is mounted a pair of elevated tracks'or ways 18 which s rpport a pair of carriages 19 and 20., Both of these carriages are shown as' intermittently moved forward and back by means of a rock shaft 2l connected with the carriagesby a pair of cranks 22. The rock shaft Imay be'operated intermittently in any desired way'as by a cam (not shown)y for example. A 'spring 23 is. shown -for pulling the rock shaft back in opposition to the cam. Each of these Vcarriages is provided with a support numbered respectively 24,.'25 and' 26. Thevsupports 24 and 215 are located 'on the carriage 19 and pivoted thereto on axes parallel with the in proper-iposition'during the entire opera" direction of motion of the carriage so as to permit them lto have a swinging mot1on.' This motion 1s caused by the reciprocation of three slides 27 which are moved by a rock shaft 28 operated in any desired way, as for example a spring 29 and cam (not shown). These slides 27 have rods 270 on which the supports are loosely pivoted to permit them to operate in all positions of the supports. On each of` the supports is a slide, these slides being numbered 30, 31 and 32 respectively. The slides 30 and 31 and the supports 24 and 25 are operated by means of' cams, not shown, or the like, through arms 33 and 34 to have a certain sequence of operation as will be described hereinafter.
The-way in which the arms 33 and 34 are connected with the slides 30 and 3l is indicated in Fig. 1, inl which the arm 34 is shown. This is provided with a rod 35y like the rods 270 passing through a slot 36 inthe slide. The arm does not move transversely of the frame, but swings so als to givethe on the frame. The slide 32 is providedfwilth a bar or comb-37 thereon liavin'g1aifse'ii'es'of" hooks 38 which constitute means engagingy the first links of the` fabric chain or chain cloth. The two.slides 30 and 31V are 'also`r` provided with bars or combs 40 and 41 whi'ich carry flower hooks 42 and upper hooks 43 respectively. hi I At the commencement of the""operation ofy makinfg'the fabric, the hooks 38'are brought' 1 up to the hooks 43 and to the jwire bending f.
deviceuand the `irst row of rihg'sfo'r links 'are Y. 'jg if j.. i made directly on the two sets of hooks. The Aicomb, 37 and hooks 38 are moved up to this position by an arm 44 which is operated inv any desired manner-, preferably by means of a cam (not shown), to engage a roll 45 onf the 'slide'andl push the slide up intof-the l position shown in Figs. `5, 6 and 7, in which casel the hooks 38 and 43 overlap so that each ring, can be made over one of ear; indicated in these igures.
the fabric taut.` Then the hooks 43 are drawn back as indicated by the arrow in Fig. 7 to the position shown in Fig. 8. Simultaneously the hooks 42v are moved for? ward by the arm 33 and the hooks 43 moved downward by the slide 27 so that the parts will be brought into the positionV shown` in Figs. 8 and v9, and then as the carriages travel across intermittently the second series of rings b will be formed', each one over two of the series a, and over one'of the hooks 42, so that the'` second series of rings will be formed in position to be engaged by the hooks 42V when the latter are drawn back,` which is the next operation of the device. Now the hooks 42 go back in thedirecton 'of the arrow in Fig. 10, the hooks 43 are to that shown in Fig. 2, except that in` that 'number of links.

It will bex seenI` that fall i J 5 .i Theinext operation of theinaeliineisto y: withdraw the arm 44, and let aiweighft46 hung on a cord or chain 47 and ypassing over. i a pulley 48 pull the comb 37 backtol keepl again brought up, and then ',dow'n to disen` gage them from the links or rings 'a and leave the two, sets of links supported by the hooks 38 and 42. This is a position similar...
case the fabric shown with an additional' j The knext row of linkse" L will then be formed as indicated in `Fi 11k les side, eithergby the hooks 42 or by the hooks f 1' 43; and in both cases the fabric is held on 7 f Y the other side` by the hooks 38 which are conf .'fst'antly under the tension of the weight 46 At each operation also the left hand slide 27 moves with .'the rightLhand'sl-ide soA as to keep the two being formed. Ordinarily in making` dish cloths from link fabrics of this kind, they are made straight across for the major portion of their Width, but are given a V-shape at the end. This is accomplished in the present machine by allowing all motions to be gone through with clear to the apex of the V, and automatically throwing out the wire-feeding and link-forming mechanism at the ends by means of an index Wheel or the like (not shown) so Vas to reduce the number of 'links formed inv each row until the last one, in which only one is formed in the mid dle. lVhen the fabric is completed it is left supported by the hooks 38 and l2 which point down. After the lastlink or links are completed the cam operates the arm 44 forward to move the hooks 38 up to the hooks l2 which causes the fabric to sag down in the middle and drop oft' the hooks. Thus the entire operation of the machine including the removal of the fabric is automatic,
For the sake of avoiding prolifrity of specification and indistinctness in the drawings, l' have omitted the illustration of the particular cams and index wheel which have been employed for bringing about the above mentioned motions of the parts. They can be designed by any skilled mechanic, as any other means may be devised for moving these `parte in the desired way.
While I have illustrated and described preferred embodiment of the invention, I am aware that the same may be carried out in many other forms and with many modifications without departing from the 'scope of the invention as expressed in the claims. Therefore l do not Wish to be limited to all the details of construction shown and described, but
