Application filed .Tune 6, 1898. Serial No. 682,634. (No model.)

To @ZZ whom it may concern:

Be it known that we, FRIEDRICH Wnvnn and CARL SEEL, subjects of the Emperor of Germany, residing at Barmenin the Province of Rhenish Prussia, Germany, have invented certain new and useful Improvements in Looms; and we do hereby declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to to the shape of the fabric to be produced;

second, by the peculiar design of the reed, which also in each case varies according to the shape of the breast-beam; third, by the special manner of arranging the mails in the heddles, which instead of lying in a straight line, as usual, are arranged in a line corresponding approximately to the general outline of the breast-beam and of the lower edge of the reed; fourth, by the race-board of the shuttle and the means for producing a clean shed; fifth, by the peculiar means for working the reed, so that it can be driven close up upon the breast-beam and beat up a longer weft-thread than the apparent width of the woven stuff.

On the accompanying drawings the new loom is shown as a whole and in various details and the manner of its working shall be explained hereinafter.

Figure l shows avertical section along line I I of Fig. 2. Fig. 2 isaplan of Fig. l. Fig. 3 is a front view seen from the left of Fig. l. Fig. 4c shows a part of the loom in vertical section, serving to explain the working of the reed and of the shuttle-race. Fig. 5 shows in front view part of the loom with the reed behind the shuttle-race and the central part of this in normal position. Fig. 6 shows one example of arranging the mails in the heddies. Fig. 7 shows a detail view of the reed G, illustrated also in Figs. 3 and 5.

In a frame A is mounted the main shaft B, which is driven by fast and loose pulleys C, and from which the other movable parts 0f the loom are set in motion, as will be explained farther on. At the right or rear side 0f the frame is placed a light wooden frame E, containing the warp-bobbins, in place of a single warp-beam, as usual, the nature of the fabrics intended to be produced by our new loom requiring different lengths of warp at different places of the weaving, and therefore special means for giving off various lengths of yarn at different places. From these bobbins the yarn is drawn in to the heddles F and the reed G, and thence around the breastbeam H. The heddling and reediu g are done as usual, with the difference only that the mails in the heddles are not arranged in a horizontal or straight line, (only for making small articles, ribbons, and the like the mails in the heddles may be arranged in a horizontal line,) but in a line corresponding in shape to the shape of the breast-beam, as clearly shown in Fig. 6. The reed also differs from an ordinary reed in this respect: its bottom stay g instead of being straight, as usual, has also the curved shape of the outline of the breast-beam. The reed further differs from an ordinary reed by the manner of its working and arrangement in the loom.

The reed instead of being arranged in a batten is here held between two guide-blocks K, which slide on two guide-bars L, mounted obliquely in the main frame. These guideblocks have brackets 7.2 surlnounting them, on which the reed is so held that when it is fully pushed backward it will stand behind the shuttle-race board, and when it is fully drawn forward-that is, toward the breast-beamits bottom stay will stand exactly, or nearly so,

in the middle over the breast-beam. The.

moving forward and backward of the reed may be done, as in the example shown, by means of cams M and levers N and O, as is clearly shown in Figs. l and 2.

The breast-beam II is exchangeable and varies in form. It receives always the shape which is prescribed by the shape of the fabric to be produced. In the example shown on the drawings it has a wavy form, resembling IOO 4is arranged the shuttle race-board.

gether a channel of half-circular form.

two side parts PP are fixtures. The central part P can be raised and lowered. The lowering has for its object to allow the reed to pass through on its way backward .before a.

new weft is laid in. VThe raising of the middle part P' of the race-board has for its object to raise all those warp-threads which do not form a clean shed, so that when the part P is raised it not only forms a continuous semicircular race, together with the two other parts, but that it also brings up the warpthreads -into place, so that they do form a clean surface for the shuttle to pass over in the Lrace-board.

lThe raising and lowering ot' the movable part P of the race-board is done by means-of cams Q, levers R, and bars S, properly arranged in the loom between the two main frames, a spring T serving to pull the levers downward and keep their rear ends in conf jtact with the cams.' 1 'The driving-gear forthe sh uttle-'the pickeri driver in ordinary looms-is arranged'as follows: At both sides ofthe main shaft bevel-i wheels U are placed, gearing together with? similar wheels U on obliquely -arranged shafts V, held in suitable brackets at the;

sidesvof the frames and atthe upper ends of',

pulled against them by springs Y, which are Txed with one end on the main frame and with the other upon arms Z, which are made' to oscillate-on a bolt a, upon which they are lkeyed andwhich is suitably carried andh'eld i in the cross-beam Z) of the frame.

bolt a are also ixed the (picker) drivers c, which,with their circularlyshaped ends,reach into lthe race-board of the fixed parts PP. It

will be observed that the bolt a lies in the,

center of the circle of the race-board.

Finally, we have to call attention to a small bar d, which'is placedexactly over the breast-y that the-reedwhen beating fast a weft-thread 'and'being driven quite forward upon the cen- .ter linefof-the beam'does not'require to raise the threads; otherwise by its movement it might easily happen that thin threads are torn, which is prevented by passing the warp over the thin bar cl.

Variations :in minor details may be made;

butinjthemain the loom described and shown 1s new, and so isits working, of which we let which are keyed volute cams W. These vo lutevcam's work against `slides X, which are" On they It `has follow a short description. This is as follows: The drawing andrheddling of the warp into the reed and the heddles having been done as usual and the yarn having been drawn over the bar d and around the breast-beam, which is roughened byvany of the known means, the shed is opened and the reed is pushed backward into the position shown in Fig. l in full lines and dotted lines in Fig. 4.' The loose part P' of the shuttle race-board is then raised and brought in position that-the race in the three parts P P P forms a continuous circular channel. The shuttle, with the weft-thread, is then driven through the shed by means of the drivers c cand their connections, and then the part P' is dropped again and the reed is pushed or pulled forward to beat the weft into l the warp tightand close to the bar d, so that the weft-threads follow as closely as possible v the outline of the breast-beam, and the now already woven fabricthat is, the intermes'hed warp and weft threads-forms the exact wrapper of the breast-beam, so that when Ithis is being turned bythe ordinary means-'that is, a regulator of any known kand suitable designthe woven stuff is pulled forward while the weaving is going on. It will, however,

i be observed that the pulling off of the woven stuff in our mode of working and with 'our peculiar `fabric cannot bedone, as usual, by the use of a cloth-beam, upon whichthe stuff is wound, the peculiarity in the 4shape of the goods produced not allowing this mode of working. The stu if, or, as we might say, the partial wrapper of the breast-beam, is taken along with it by its rotation so much as to givesufiicient hold to it upon the breast-beam that it will be able to pull Aforward the warp. It then is taken off simply by carrying it over a barf and vis then taken up by a suitable receptacle vplaced underneath the loom, or it may be allowed to fall on the ground.

Thegist of the invention consists in this, that the loom is so constructedand'so worked that, first, the reed is pulled `forward and beats the weft-thread fast only Iright up in IIO the line of tangence between the warp-threads and the breast-beam, or-at any rate in aline as close Itothat line of tangence that, practically speaking, the line given to lthe weftthread has the form of the outline of the breast-beam and that it cannot anymore alter this form or take another shape,as is the case in ordinary weaving, where the weft is beaten tight at a certain distance from the beam, and that, secondly, the reed isenabled to distribute a greater length of weft-thread than corresponds to the real length ofthe breast-beam. l'In order to be able to 'bring up the reed into the said position and beat the vweft tight upon the breast-beam itself, it is necessary that the bottom stay of-the reed corresponds in its vgeneral-form to the general outline of the b reast-beam. Afurther condition is that means are provided to raise the warp-threads of the lower shed so as to form a clean shed for the shuttle to pass through.

The mechanisms nsed for carrying out these ideas are of minor importance, and they may vary in construction according to the general arrangement of the loom.

Having noW particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, We declare that what We claim, and desire to secure by Letters Patent, is-

l. In a loom for Weaving shaped fabrics, the combination of a breast-beam conforming to the shape desired, with heddles having their mails arranged in a line corresponding to the contour of the said beam, a reed having a bottom stay of shape also corresponding thereto, and the necessary actuating and connecting` mechanism, substantially as set forth.

2. In a loom for Weaving shaped fabrics, the combination of a breast-beam conforming to the shape desired, with a bar d fixed closely over the breast-beam near the line of tangency of the Warp-threads therewith, heddles having their mails arranged in a line corresponding to the contour of the said beam, a reed having a bottom stay also of corresponding shape, and the necessary actuating and connecting mechanism, substantially as set forth.

3. In a loom for Weaving shaped fabrics, the combination with a breast-beam conforming to the desired shape, of heddles having their mails arranged in a line corresponding to the contour of the said beam, a reed having a bottom stay of shape also corresponding thereto and the necessary actuating and connecting mechanism, the length of the reed at the top being equal to the total length of the Working part of the breast-beam, its bottom being of equal length With the breastbeam and the reed-bars converging from the said top toward the said bottom substantially as set forth. l

In testimony whereof We have affixed our signatures in presence of two Witnesses.
