LOOlVl FOR NEAVING NARROW FABRICS.

SPECIFICATION forming part of Letters Patent No. 675,084, dated May 28, 1901. Application filed December 1, 1900. Serial No. 38,348. \No lIlOdei-l To all 1072/0712, it Wtay concern:

Be it known that we, NICOLAS CHAIZE and JACQUES GHAIZE, citizens of the Republicof France, residing at St. Etienne, in the department of Loire, France, have invented certain new and useful Improvements in Looms for Weaving Ribbons or Narrow Fabrics; and we do declare the following to be afull, 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 had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to looms for weaving ribbons or narrow fabrics; and it consists in an improved arrangement of the shuttledriver mechanism.

The improved sh Little-driver mechanism for which the presentapplication is made is shown in the accompanying drawings and particularly described in the following specification.

Figure 1 is a front elevation of the batten or lay fitted with the improved shuttle-driver mechanism. Fig. 2 is a plan of the same. Fig. 3 is a detached enlarged longitudinal section of the shuttle to be used therewith, and Fig. 4 shows an enlarged elevation of the shuttle-holder adapted to the improved shuttles and system of driving same.

The improved system of driving the shuttles, differing considerably from those at present in use, consists of, first, shuttle-holders a a, and, second, of reed-frames b, independent of the shuttle driving and holding appliances.

The reed-frames b are formed of metallic cages provided with grooves cat the bottom, in which are placed the reeds d, which are held solidly at the top bya band of iron covered with wood. In the band of iron also exists a slide or groove 8 to receive the top of the reeds. The reed-frames and their wooden bar are supported by jointed rods 6 from the top of the loom-frame. A grooved cam placed at each side of the machine, driven by any suitable shaft of the loom, may be utilized to give the beat-up motion to the reed-frames b, which is a rapid reciprocation after the shuttle has passed the shed and a rest during five-siXt-hs of the shuttle movement.

The shuttle-holders a a. are fixed upon fiat rodsf and f, furnished with racks g and g, preferably attached to the sides of said rods, each one making half the total travel of the shuttle to and fro through the shed of the ribbon or narrow fabric. Upon one of the said flat rods-say f-are fixed all the lefthanded shuttle-holders a and upon the other,

f, are fixed all the right-handed shuttle holders a. It will be understood that when the shuttles u are all situated to the left of the ribbons and held in the holders a the actuation of the rodf by suitable means, hereinafter described, carries the shuttles into the shed and into engagement with the holders a to the right of the shed, which then by the rack g on the rod f continues the travel of the shuttle out of the shed, while the rack g, the rod f, and the holders a thereon remain at rest, awaiting in their turn the return of the shuttles by the holders ct, the rod f, and the rack g from right to left. The racksg g are operated by the wheels h and it, having teeth upon one part only of the circumference in order to operate f and f successively each for the half-travel of the shuttles to, one half of such travel carrying the shuttle into the fabric and the other half carrying the shuttle clear of the shed and ready to make its return travel.

The shuttle-holders a a are rectangular in form and hollow. In the interior slides a metallic piece to, having oblong slots opposite the round holes in the outer frame, by which the pointed nose to of the shuttle u enters.

From the top edges of the slots in the piece 20 project downward metal pins 1:, adapted to engage or look into the holes in the points or noses u of the shuttle. The piece 10 has also a foot at its lower extremity, projecting below the frame of the holder, and the piece 11; tends to return always to its lowest position both by its,weight and by a recoil-spring at the side of the holder. The bars or rods ff are arranged to slide on rollers l, and on the same supporting-brackets under each ribbon are fixed planes it, with inclined ends, onto which ride the projecting feet of the sliding pieces w in the holders a a, so that the former are lifted to release and receive the noses of the shuttles and are permitted to drop and lock the shuttles in the holders during travel.

Upon each rack is fixed a depending bracket carrying a horizontal pin and roller j at its extremity, which engages against the inner face of a projecting flange 7c of the toothed wheels h h. These rollers j assure the seizing of the shuttles by the holders a a and prevent any recoil of the said holders when receiving the shock of the incoming shuttle. Just as the holder reaches the limit of its movement in pushing the shuttle through the shed the flange it moves in behind the roller j and prevents it and its bar from recoiling. On the reverse movement the flange is withdrawn from behind the roller just as the shuttle begins to be carried away from the shed by the holder into which it has been thrust. The roller is used to lessen the friction of the parts as the flange slides past it. A fixed stud would be the mechanical equivalent of the roller.

The operation of the above driver mechanism is taken from a main shaft m of the loom by means of a pinion n and wheel 0 upon a counter-shaft carrying two bevel or miter wheels engaging alternatively with a third bevel or miter wheel q upon a shaft 0, this being a Well-known form of reversing-gear. The shaft '1' carries at its other extremity a large chain sprocket-wheels, from which a chain'operates another small sprocket-wheel t, fixed on the shaft 6, carrying also the wheels h h", operating the racks g g and the shuttleholders a a in their successive and reciprocating movements.

The shuttles are of the convenient form shown in Fig. 3, having at each end a point or nose u, adapted to enter the holes -in the holders a a and having transverse holes in the said noses to admit the engagement of the pins '12 of the sliding piece to of the shuttle-holders. These shuttles, which are entirely in metal, receive very large cops or bobbins 01:, since the shuttles are longer than the width of the ribbon, which is necessary for the operation of the shuttles by the sliding holders, as above described.

The holders can take and operate simultaneously any convenient number of shuttles by making a corresponding number of reception-holes and engaging pins therein above one another and are adaptable for ribbons of broch or velvet. In the case of broch the operation of the shuttles may be modified as desired.

In carrying our invention into practical operation we prefer to construct the frame of the loom of metallic tubes or hollow bodies of metal of any suitable dimensions, forms, or arrangements connected together by couplings, such as right and left hand screws or theirequivalents, and bent or curved or otherwise shaped in such manner as to produce a frame which is strong, light, and elegant in appearance.

Having now described this invention, what we claim, and desire to secure by Letters Patent, is-

I. In combination, in a loom for weaving ribbon or narrow fabrics,shu ttle-holders having hollow bodies and holes in one vertical face adapted to receive the shuttle-nose, a vertical sliding piece within each of said hollow bodies containing apertures corresponding to the shuttle-holes in said bodies, pins on said sliding piece projecting downwardly into said apertures and adapted to engage or lock the shuttle-nose, sliding bars carrying all right-handed and left-handed holders respectively, springs attached to the bars and the sliding pieces, and fixed inclined planes adapted to force up the internal sliding pieces against the tension of the springs and to allow the same to thereby release and lock the shuttle-noses respectively at suitable times, substantially as described.

2. In combination in a loom for weaving ribbons or narrow fabrics, shuttle-holders adapted to pass a long shuttle from side to side of a ribbon or narrow fabric; two parallel sliding rods, one carrying all holders to left of the ribbons, the other carrying all holders to the right, roller-supports for said rods; racks 'on' under faces of said rods; two segmentally-toothed wheels on same shaft, engaging respectively into said racks; and provided with sectional flanges, the toothed segments being opposite to one another on said wheels; a check-roller on each rod, engaging with sectional flangeon each wheel respectively; and means to give a complete revolution to said wheels alternately in opposite directions, substantially described.

In testimony whereof we a'fflx our signatures in presence of two witnesses.
