ALEXANDRE BARBIEB, OF LYON, FRANCE.

LOOM.

Application filed May 27, 1913.

To all whom it may concern Be it known that I, ALEXANDRE BARBIER, a citizen of the French Republic, residing at Lyon, in France, have invented certain new and useful Improvements in Looms, of which the following is a specification.

This invention relates to improvements in looms, and is for the object of increasing the capacity of the figuring mechanism by providing for more extended transverse displacements thereof, while simplifying the operating mechanism so as greater speed of the loom can be attained.

The annexed drawing illustrates the invention.

Figure 1 is a front view of the loom. Fig. 2 is a side view thereof.

The bar a of the figure mechanism is mounted as usual in front of the ordinary batten b on an oscillating frame 0, but contrar to previous mechanism of the kind, as for instance in the patent to Barbier et al., 750,015, January 19, 190 1, the frame 0 only moves forward and backward, the bar a being arranged to slide transversely on the frame in order to carry the shuttles to points where they are to operate. Consequently this movement not bein interfered with by the lower mechanism 0 the loom can have greater amplitudes of movement than hitherto which allows of executing spaced patterns up to 12 centimeters in width. The weight of the parts to be put in movement and the passive resistance being much less, the loom can be given a greater speed than hitherto.

The frame a carries the figurer by means of vertical sliding rods 1' provided with sprin r which maintain the figurer at the top 0 its stroke.

The transverse movement is given to the figurer by the jacquard by means of the cord d and the antagonistic spring 9 acting on a cylinder f provided with helical projections each corresponding with an adustable abutment e governed by the acquard.

The cylinder 7 is connected to the figurer by a cord h and a lever 719. When the figurer should be displaced one of the abutments 6 corresponding to the amount of displacement is raised against the cylinder, the cord at being drawn downward is relaxed, the spring 9 draws the cylinder against the Specification of Letters Patent.

abutment where it stops having placed the figurer at the position it should occupy.

The figurer drawn to the right, Fig. 1, by the cord h is drawn to the left by a spring j attached to a fixed point of the frame 0 and to the lever is, connected to the figurer by a pin 2' extending between two plates fixed to one of the arms m m which can turn on their axes in order to tilt the figurer forward at an angle of 45 whereby the shuttles are brought forward which allows of easily changing them. By this movement the pin 1? is disengaged from its plates and the lever is drawn by the spring j by the release of the lever is, returns toward the left and as it carries the pulley n of the chain 0 which drives the shuttles, as will be hereinafter described, said chain relaxes which further facilitates the filling of the shuttles. The shuttles are operated by the usual rack and pinion drive, as indicated in Patent No. 624,039 to G. F. Hutchins, May 2, 1899, or as in the patent to Barbier et al., #750,015, January '19, 1904, or in any suitable manner to accomplish the foregoing and subsequent functions.

When the loom is in action for weaving the fabric ground, the frame 0 rests in front with the figurer supported against the breast-beam of the loom; when the figurer should enter into operation two catches u u hinged on the frame a and operated by the jacquard engage with the hooks p p immovably fixed to the batten which is then accompanied in its movements by the figurer as long as the jacquard maintains the catches u in engagement.

Two evers s articulated to the frame a and connected to the figurer by rods t are raised during their backward movement by a movable inclined lane '0 actuated by an eccentric device which displaces it at the return movement, providing for a quiet descent and a quick rise of the figurer for tensioning the wefts. The inclined planes thus cause the figurer to take a lunging movement while compressing t e springs r 1' whereby the shuttlecarrlers are introduced into the open shed-ofthe fabric. At this movement the shuttles ass from one carrier to the next by means 0 the following mechanism.

The principal shaft 1 of the loom which operates the batten b is provided outside the frame 16 with a toothed sector 2 which can gear with a wheel 3 mounted on a lever 4:, the engagement being effected at the required time by a cord 5 of the jacquard acting on a bell crank lever 6.

As long as the figurer is not in action, the sector 2 turns without engaging with the Wheel 3, but immediately it should operate the jacquard acts on the cord 5 which tilts the lever 6 which lifts the lever l carrying the Wheel 3 and brings it in engagement with the sector Thercupon at each rotation of the shaft 1 a semi-revolution of the wheel 3 will be effected, the said wheel being held between its rotations by a spring bolt 7. At each semirevolution of the Wheel 3 a rod 8 articulated thereon at 17 tilts a rocking arm 9 pivoted at 18 to the frame 16, first in one direction and then in the other, the other end of the arm 9 thereby imparting a reciprocating rotary movement to a toothed wheel 11 by means of a rack 10 pivoted to the arm 9 at 19.

On the same axle as the wheel 11 a grooved pulley 12 is keyed guiding a chain 0 which passes over the pulleys 13, 14, n and operates the pulley 15, governing the passage of the shuttle first in one direction and then in the other. The amplitude of the shuttle movement is regulatable by means of slots 20, 21 of the rocking arm 9 in which guide slots the pivots 19 and 22 of the members 10 and 8 can be adjusted.

If the figurer comprises several series or rows of shuttles, a similar movement will be arranged for each.

The chain or the chains 0 could be replaced by wires or cords, fixed at one point on the pulley 11.
