SPECIFICATION forming part of Letters Patent No. 671,148, dated April 2, 1901.

Application filed September 10, 1900. Serial No. 29,493. \No model.)

To all whom it may concern.-

Be it known that I, THOMAS A. ROBINSON, a citizen of the United States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Gauze-Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,,reference being bad to the accompanying drawings, and to characters of reference marked there on, which form a part of this specification.

This invention relates to looms; and it has reference particularly to that class of looms which are employed for weaving gauze or other similar fabrics of the kind wherein is most commonly found that pattern of interlocked weave which is produced by carrying every alternate warp-thread over its neighbor first in one direction and then in the other, alternately with the forming of the sheds and the carrying of the weft-thread or filler thereth rough.

The invention consists in the improved loom of the character above indicated and also in the combinations of its parts, constructed and arranged substantially as will be hereinafter particularly set forth and finally embodied in the clauses of the claim.

The invention is fully illustrated in the accompanying drawings, wherein- Figure 1 is a side view of my improved loom. Fig. 2 is a top plan view, slightly enlarged, of that end portion of said loom which appears in Fig. 1. Fig. 3 is a vertical sectional view of said loom, taken just back of the harness and looking toward the front of the loom. Figs. 4: and 5 are enlarged detail views showing the batten and reed in section and also showing the mechanism whereby the sheds are formed in the body of the goods. Figs. 6 and 7 are plan views illustrating the mechanism whereby the weave is produced. Figs. 8 and 9 are respectively a side view and a sectional view, the latter being taken on the line as m of Fig. 8, of a certain traversemotion mechanism; and Figs. 10 and 11 are views illustrating the manner of efiecting the desired weave.

a designates the loom-frame, and b an auxiliary frame which extends from the rear end of the loom and supports the rolls 0, d, and e, the former oneof which is for the selvagewarp, while the latter two are for the bodywarp, the roll cl carrying one half of said bodywarp, (every alternate thread thereof,) while the roll 0 carries the remainder.

fdenotes the take-up roll, disposed at the front of the loom in the ordinary manner and driven from the main shaftg by any suitable mechanism, and h is the batten carried by the fulcrumed lay-swords t', which are actuatedfrom another shaft 71 through pitmenj. On the batten is suitably arranged the reed 7c. The shaft 9 carries two cams 5, set to alternately raise two levers m, which are suitably fulcrumed in a convenient part of the loomframe and to which are connected cords 7t, passing under pulleys o and in turn connected to a harness mechanism, which said levers are adapted to raise and lower and which comprise two sets of heddles p, heddle-levers q, cords '1", extending downwardly from said heddles, around pulleys s to said levers q, and other cords i, extending upwardly from said heddles over pulleys u to the levers. This harness is adapted to control the selvagewarp, (marked 0) on the drawings,) which is thereby manipulated toward the production ofthe ordinary plain weave. t

On the shaft 9 is mounted a cam 02' of the shape substantially of the figure 8, and this camcontrols a lever w,which is suitablyfulcrumed in the frame and carries a roller w, bearing against the periphery of said cam.

On the back of the batten is arranged a pair of small brackets y, in which is pivoted a frame .2, from which projects a series of needles 1, all disposed in a common plane. This series of needles is preferably as wide as the dent-space of the reed, exactly back of which itis disposed, the needles, furthermore, being situated in opposition to the spaces between the dents of said reed. From the frame a project two arms 2, connected to which are cords 3, which combine in a single cord aand then pass under pulleys 5 before being connected to the le verw. To said arms are likewise connected suitable springs 6, which are suspended from the arch of the loom-frame. These springs normally tend to maintain the series of needles horizontal, as shown in Fig. 4, and since when the needles are in this position and the filler w is hearing against one of the hollows of the periphery of the cam 02 the cord connecting the frame ,2 and the lever to is taut said lever will be constantly maintained in operative contact with said cam. In order that the needles may dip or turn into the substantially horizontal position far enough, the upper face of the batten, just back of the reed,'is cut away, as shown in Figs. 4 and 5 at '7. A glass rod 8 is so arranged on the frame zas to be always uppermost what-ever the position of said frame.

. 9 designates a reed whichis arranged back of the harness, being suspended from the upper portion of the loom-frame by suitable cords 10, preferably made adjustable in any desired manner. Through this reed, as well asthrough the reed it, both selvage and body warp extend. Two threads, one from each body-warp roll, pass through each space of the reed 7c and through the corresponding space of the reed just referred to. One of these threadsi. e., of the body-warp marked 12extends through the eye of the corresponding needle of the series of needles 1, while the other2'. e. ,of the body-warp marked 11remains free. The rolls d and e and the glass rod 8 are so arranged that the warp 11 is just kept in contact with said glass rod by the reed 9, which is approximately alined with them at its top portion, while when the needles are raised to their vertical position the warp 12 will be elevated, (see Fig. 5,) a shed, which generates at the back from this reed 9, being thus formed.

Before being wound upon the take-up roll f the woven material extends over a traverse-roll13. At one end this roll has a spindle let, which rests on a grooved roller 15, mounted on the back of the breast-beam 16 of the loom, While atthe other end of said roll is a trunnion 17, having a shoulder 18 and resting in a recess 19 of a block 20, there being a groove or depression 21 in the recess, which fits the shoulder of the trunnion. This block is carried at one end of a non-revoluble spindle 22, which is arranged to reciprocate in a bracket .23, projecting from the breastbeam and to a pin or screw 24:, extending from which is pivotally connected one end of a lever 25, also carried by said bracket, being fulcru med on a pin 26, which projects therefrom.

y from the bracket 23, is suitably journaled a tween these two sprocket-wheels said chain In arms 27, which extend downwardly.

also passes under another Wheel 34, journaled in a suitable bracket 35.

The filler is carried through the sheds by anysuitable means, as the shuttle 3a, which may be controlled in any desired manner.

In describing the operation of the loom attention is to be first called to the fact that the action of the cam v is such that the needles 1 will be elevated every time the batten swings back, falling as it swings forward, and that the traverse of the roll 13 is a motion that is alternately to the right and back and to the left and back, starting from an intermediate position. The batten being back and the sheds being formed in the body as well as in the selvage warp by the needles and harness, respectively,thefiller is carried therethrough. Thereupon the batten swings forward to beat up the filler, and as it does so the points of the needles drop into the space or recess 7 of the batten, depressing the rear portions of the threads 11 below the threads 12. The beating-uphaving been effected by the reed 7c, the roll 13 is traversed to either of its extremes of movement, which action, since the needlepoints are disposed very close to the back of the reed and since the reed-spaces are somewhat. wider than those of the ordinary reed, effects the carrying over of the threads 12 relatively to the threads '11-. This carrying over of the threads 12 is brought about by virtue of the fact that their rear securing-points in the needles are quite near the forward securing means which the roller 13 affords and which is common to both sets of threads, whereas the securing-points of the threads 11viz., in the reed 9 are considerably remote from said forward securing means. The threads being thus crossed, the batten again swings back, the needles at the same time rising, and the harness acting to form the sheds in the warp,

said occurring alternately with each carrying through of the filler.

In order that the roll may perfectly exert its influence on the warp as it traverses, said roll should be covered with baize or have its acting surface suitably adapted otherwise to the same end. I do not wish to be limited to the exact structure nor to the precise combinations and arrangements of parts which'have been hereinbefore particularly described; but

What I claim, and desire to secure by Letters Patent of the United States, is
