To all whom t may concern.

Be it known that I, fALois TscrrnRNn, a citizen of the Swiss Confederation, and residing at Rorschach, Switzerland, have invented certain new and useful Improvements in a Machine for Filing Fabric, (for which I have filed an application in Switzerland June 17, 1919, No. 83676,) of which the following' is a specification.

The present invention relates to a new and improved machine for piling fabric, and more particularly for folding a long strip of material, such as for instance gimps, edgings, webbings, bindings, bandings, galloons, braids, and the like, into a succession of superimposed loops or layers, and the machine includes a two-direction reciproca-ble fabric supporter, a one-way reciprocable looper, and a stationary fabric gripper, together with means for operating the several mechanisms in timed relation, for quickly and reliably pilin@V the ,fabric into loops or layers of required ength.

My invention will best be understood when described in connection with the accompanying drawings, in which Figure 1 is a front elevation of the machine; Fig. 2 is a planland Fig. 3 a bottom view thereof; Fig. 4 is a' the direction of arrow A of Fig. 2; Fig. 5 is a sectional view on line a-b of Fig. 2, and Fig. 6 is a plan and Fig. 7 a partially sectioned side view of a detail, on an enlarged scale.

From the machine table 2, which rests on the corner feet 1, 1', 1", 1', 1, depend near the one side edge the bearings 3, 3 in which a shaft 4 is journaled, on which latter are fixed the drive wheel 5 and the bevel wheel G. A second shaft 8 is journaled in bearings 7, 7 rectangularly to shaft 4, with which it is operatively connected by a bevel wheel 6 meshing with the bevel wheel 6. ly rotating the drive wheel 5, obviously, the two shafts are correspondingly rotated. To the shaft 4 is further secured a grooved cam member 9 which serves to oscillate the spur wheel 12 by means of the meshing toothed segment 11 of an interposed rock lever which latter is acted on by the draw-spring 10 (Fig. 3). The spur wheel 12 also meshes with a rack 13 fixed to a carriage 15, which latter can reciprocate rectangularly to the direction of the fabric feed in suitable guide cheeks 14 arranged on the table 2. On the carriage 15 a rod 17 is vertically displaceably mounted in guide members 16 (Fig. 5) from which rod at the upper end extends a carrier arm 18 to which in turn an angularly bent fabric supporting arm 19 is secured with capability of adjustment in the direction of fabric feed. 0n the lower end of rod 17 is mounted a roller 20 adapted to rest on a cross-bar 21', whose ends are linked to rock arms 21 pivotally suspended from the machine table. A double-armed rock lever 23 is acted on at its shorter arm bythe cam portion 22 of a revolving cam disk 22 fast on shaft 3, while its longer arm cooperates with the cross-rod 21 for periodically raising or lowering it and with it the rod 17. rfhis cross-rod 21 is guided and limited in its reciprocatory movements by the guide and stop members 24.

The described mechanism allows ofthe supporter 19 being readily displaced in vertical direction as also horizontally in a direction'rectangular to the direction of the feed of the strip of material S (Fig. 2).

To the table 2 is further secured a bearing 25 journalinga stud 26 which supports a crank wheel 28 driven from the main drive by bevel gearing 27. To this crank wheel is linked the crank rod 29, the farther end of which is pivotally secured to the link 3() whose lower end is fulcrumed on the fixed rod 31 and whose upper end is pivotally connected to a short link 32 the'other end of which is pivoted to a slide 33'. The latter travels on a fixed guide member 34 and carries a traveler or looper 35 which by the described mechanism is reciprocated in the direction of fabric feed.

The shaft 8 carries at its free end a cam disk 36 (Figs. 3 and 4) designed for cooperation with a swing lever 38, linked at the one end to a fixed rod 37 and at the other `end to a draw rod 39 whose respective other end is pivotally connected to the one arm 40 of a rocking gripper j aw, whose other free end 42 clampingly coacts with a plate 44 resiliently supported on a spring 43. A spring 41 normally retains the gripper in the closed position.

The fabric supporter 19 is adjustably secured at its inner end to the carrier arm 18 in any suitable manner, yfor instance as shown by way of example by a nut-locked wedge member, so that the relative position of supporter and member 18 can readily be varied for the purpose of adjusting the initial position of the supporting rod 19, which then determines the lengths of fabric measured off at each operation,

The supporter 19 further is guided in a yoke member 45 which is readily adjustable within a groove 46 in the table 2 by means of the set screws 47 and it serves at the same time as lateral guide and stop for the material being piled. A plate 48, preferably covered withfelt or the like, is arranged on the table opposite to the yoke member 45 down upon which the material is pressed bythe supporter on the latters descent and during the looping operation.

For depositing folds or layers of varying lengths the supporter, as described, can be adjustably displaced in the direction of fabf ric feed, suitable indicating marks aiding in such adjustment.

For the purpose of controlling the extent of throw of the reciprocating looper 85 the link 30 and its actuating crank rod 29 are connected by a suitable pin and slot arrangement, as shown in Fig. 8; or if preferred the crank rod 29 may be adjustably secured Vto the crank wheel 28, as well known in the art.

The operation of the machine is the following: The strip of material S (as shown a length of .embroidered edging) is so laid on the table that its unembroidered edge contacts with the'yoke member 45, the fabric starting end being clamped in the gripper and the fabric introduced between the supporter 19 and-,the plate 48 and then passed over the looper rod 35. The drive Vwheel 5 is now suitably rotated which causes the looper to move from right to left above'the supporter 19 toward. the gripper; the latter is openedy and seizes between its presently closing jaws the just brought in fabric loop and holds vit during the return stroke of the looper into its initial position. Meanwhile the supporter ascends and simultaneously withdraws laterally `from out of the fabric loop. After the looper has passed beyond the supporter the latter again moves forward over the fabric and descends down upon it for again holding it pressed against the plate 48 and supporting the new layer of fabric during the ensuing formation of a new loop by the looper repeating the described 'recipe rocatory movement.

What I claim is l. In a machine of the character set forth, in combination, a fabric supporter adapted to reciprocate in vertical direction and also i in horizontal direction crosswise of the direction of fabric feed, a stationary fabric gripper7 and a fabric looper adapted to reciprd cate in horizontal direction lengthwise of the direction of fabric feed, and means for operating said parts in timed relation.

2. ln a machine of the character set forth, in combination with a table and a main drive, a fabric supporter and means for reciprocatingly moving said supporter in a direcltion crosswise of and also vertical to the fabric feed, a reciprocable looper and means for moving it parallel to the direction of fabric feed, a gripper, and means for clampingly operating ft for seizing the formed fabric loops, the several said mechanisms all being operated from said main drive iny timed relation.

3. In a'macbine of the characterl set forth, in combination with a table and a main drive, a fabric supporting unit, comprising a carriage and means forreciprocating said carriage crosswise of the direction of fabric feed, a rod vertically displaceably mounted in said carriage and means for periodically vertically reciprocating said rod, a carrier arm eX- tending horizontally from the upper extremity of said reciprocable rod.l a fabric supporting member secured to the outer end of said carrier arm` with capability of relative adjustment in the .direction of `fabric feed; a Afabric looper and adjustable means for reciprocating it parallelly to the fabric feed, comprising a carriage slidably mounted on said table and a crank driven link motion for Vreciprocating said carriage in timedrelation tosaid fabric supporter; and a gripper device and means for operating it in timed relation tothe operation of said looper.

In testimony whereof I have affixed my signature in presence of two witnesses.
