.. Specification of Letters Patent. Patented Dec, 28, 1909.

. Application filed October 31, 1908. Serial No. 460,400.

To all whom it may concern:

Be it known that we, Ann one of Basel, swltzerland, and HANS KUNY, of

which the following isa full, clear, and exact SPQC1fiCilt-10D This nivent on relates to a loon'r for weaving ribbon, particularly velvetisribbon 1n 1 which the driving mechanisms for the healds (harness) and for the shuttles are so arranged with reference to that of the lay that for each stroke of the lay the shed is twice opened and the weft laid in twice. In consequence of this arrangement it is possible for our ribbon loom to work more quickly and to furnish a greater length of ribbon in a given time than the ordinary ribbon loom.

In the accompanying drawings: Figure l is a partial front View and Fig. 2 a side elevation of an embodiment of the invention.

The main shaft (4 of the loom is driven from the pulley device 6 by means of the toothed wheels 0, (Z. To operate the lay or batten 0 there is an adjustable crank pin f on the wheel 0 which is mounted upon the main shaft 0, and this crank pinis connected by a connecting rod 9 with the arm ii of the lay or batten c which is pivoted at i in such a way as to be compelled :to partake of its motion. Thus for each rotation of the main shaft 0 or of the wheel 0, the lay or batten c executes a to and-fro movement, that is to say a beating-up and a return stroke.

The jacquard of the loom for controlling the heddles or healds is a double acting ma chine of the usual type with two blades, two sets of wires and two jacquard rollers, so that its various parts need not be represented and described in detail for the present purpose. It suflices to state that the heddles or healds are attached to oscillating members connected tqtwo horizontal rows of hooked jacquard g wires alternately through the medium of two series oflift-ing '-wires, "tlietwo jacquard rollers in such a wayj'that ea'ch time. that jacquard blade which moves forward draws with it the acquardwires which-have not heenlifted by the corresponding lifting wires and thus HANDsonIN,

its motion, I and the toothed wheel en: gages with a toothed wheel q mounted eccentrically upon the pin 0 while a -spur wheel 1' connected with the toothed wheel' g engages with the wheel a mounted upon the 55' or at each working stroke of the battenor lay. Indeed, as will be-seen fronithe' draw .ing, the diameter of thewheel cis double that of wheel 1', and the number of teeth'of revolution of the main shaft a of the loom,

r is half that of p, so that at each rotation .of

the main shaft 64 the elliptical toothed wheel 7) is turned once and consequently each jacquard blade is. swung to and fro once and the shed thereby twice opened.

As will be seen from Fig. 1, the batten.

or lay c is a so-called double batten 2. e. a batten with two rows of shuttles j-lying The shuttles j of each row are moved to and fro in their paths in the known way by means of a toothed. rack 3 moving to and fro. The toothedracksc for the two rows of shuttles are connected .at-

t and 23 respectively, with a treadlee by means of two ties usecured to them atthose points and shown by dotted lines, these ties being carried upon rol-lers, both upon the,

connected at w and a: by two ties 3 (indt cated by full lines) secured to them at those points with a treadle a, these'ties being carried on rollers on the batten in a direction over rollers. These treadles o, e are articu lated to the framing of the loom at 1 and .106 opposite to that/of the ties u, and above also- T 'rmidles v and 2 are each alternately moved .up and down once by the cams 2 and 3,

tively one to another than when one treadle (2' for example in Fig. 2) is at its highest rotation of the main shaft a from which a I acting positivel opened and closed upon each occasion, and

parted to them by the action of two cams 2, 3. The cams 2, 3 are mounted directly upon the main shaft a of the loom. They have a different shape of so to speak com- 'alenientary form and are so arranged relapoint, the other treadle is held at its lowest position by its own cam, with the result that the shuttles of both rows stand at one mar their stroke, and upon reversal of the' position of the treadlesare carried to the other end of their stroke. Thus at each stroke 'of the batten or lay results the which together with the treadles v and z, and the parts combined with them represent the drivin mechanism for the shuttles, 1 in every sense so that the shuttles of the two rows are simultaneously moved once to and fro, so as to lay in two shotipn each occasion, the arrangement being so contrived that the motion of the shuttles in one direction follows immediately upon one of the two openings of the shed brought about for each stroke of the battenby the jacquard driving mechanism, and the movin of the shuttles in the reverse direction immediately after the second opening of the shed.

The driving of the double action jacquard machine by means of the elliptical toothed wheel 1) has the advantage that the healds are so actuated that the shed is rapidly every time affords a proportionately long open condition of the shed, so that all contact of the shuttles with the threads of the warp is prevented.
