ping" with COlIiPltG' absence of shock by t which damage: producedin looms as the-coirata greater speed; it is not sequence of; violent arrest is'avoided; and by which a notable: increase in: eiliciency results sinceinadditionto permitting the operation necessary for the-loom to bexstopped, tor the repairs thus rendered necessary. a a
It isvknown that the diminution in the length of the, connecting rodf'whioh transmitsrtlie movement'ofl'thecrank shaft to the beater increases the time available for the passage of the shuttle, and the inventionhas for its object to utilize this increase in time forgiving a greater extent of movement than the normal to the stop commonly called the frog, which serves to cause the arrest when the arm commonly called the stop rod dagger shuttle boxes comes to be engage The movement of the stop which in ordinary looms is about a centimeter, may owing to the shortening of the connecting rod be more than three centimetres, and this 1ncrease permits of obtaining a progressive braking of the fly wheel of the crank shaft before (the movement of the stop having or fin er operable by the tongues of the terminated) the total interruption of the operation is produced. For obtaining this progressive braking, the rod connecting the stop to the brake operating member is constituted of two or more parts articulated in such manner that while the said stop drawn by V the arm bearing upon it efl'ects traction upon the rod, the parts are displaced one with reference to the other or to the others, overcoming the action of one or a number of springs which tend to maintain them in the position which corresponds to the minimum length of the rod, simultaneously actuating the said brake operatil'ig member with a force progressivelygreater according as the distention of the said springs increases. In this way it becomes possible for the loonTtb operate at a greatly reduced speed.
The invention is diagrammatically illustrated by Way of example in the accompanying'drawings, in which Figure l is'a side elevation and Figures 2 and 3 respecproduoingthe stoptively cross sectional endielevation and plan,

part .6 has a downward; extension carrying andl'fl: of: whichathe apin lf uponivhich are'pivotedgtavo small Y paralleldisposed levers-'9,- pivoted also: upon a pin 10 which traverses the slot or hole 8 in the part 6, the levers being connected at the upper isconnected at one extremity the spring 11', which by reason of its disposition can be distended to an extent greater than corrre sponds to the relative displacement of -the parts 6 and 7. Forrestoring the parts to the position of normal operation of the loom, the stop 1 is submitted of. a rod 13 to the action of a strong spring 14 fixed to the frame 15 by the studs 16, 16.
The operation of the mechanism is as follows; The stop 1 drawn by the armor stop rod dagger or finger engaging its notch 2 draws the rod 6 and 7 which causes the constantly by means part by another pin to which application of the shoe l-upon the fly wheel 5 with a slight pressure at first but increasing progressively according as the part 7 drawn by the stop 1 and the part 6 retained by the shoe 4 causes the tension of the spring 11 to increase.
The stop 1 carries a which from the first moment of engagement of the arm upon it operates to throw the loom out of gear in causing the belt to pass from the fixed pulley of thecrank shaft to the loose pulle v', .after which during the movement of the said stop it produces the progressive braking of r the movement through the inertial possessed by the V fly wheel, the total arrest being efi'ected finally, when the speed of the crank shaft having then diminished, the stopyl arrives at the end of its movement and the brake operating rod, is no'longer extended owing toth'e finger or projection fact that the pin 10 has passed along the '7 movement of the parts of thesaid'dra'w rod ment of the stop and has reached the end of thewslot.
It will be understood thatthe operation of the mechanism produces the stopping without shock, damage is avoided notwithstanding that the loom is operated at a mits of the employment of a short rod for transmitting the movement of the crank shaft to the beater.
I claim:
1. In looms having fixed reeds, a crank shaft, and a frog adapted to be engaged by a stop rod dagger or finger to actuate the stopping mechanism, the combination of stopping mechanism comprising a brake shoe, means such as a fly wheel mounted upon the crank shaft of the loom to cooperate with the said brake shoe, a draw rod connecting said frog and said brake shoe, the said draw rod consisting of two parts movable longitudinally with respect to one another, means of connectionbetween the parts of the said draw rod providing lost movement between the said parts, and means comprising a spring by which the relative whereby the possibility of high speed which per 1 causes the gradual application of pressure by the brake shoe until the lost movement between the parts of the draw rod is taken up, substantially as hereinbefore described.
2. In looms having fixed reeds, shaft, and a frog adapted to be engaged by a stop rod dagger or finger to actuate the stopping mechanism, the combination of stopping mechanism comprising a brake shoe, means such as a flywheel mounted upon the crank shaft of the loom to co-operate with thesaidbrake shoe, a draw rod connecting said frog and said brake shoe, said draw rod consisting of two parts movable longitudinally means of connection between the parts of the said draw rod providing lost movement between the said parts, a spring, and means comprising a lever connected to the said spring and the parts of the said draw rod causes the extension of the spring and the gradual application of pressure by the said brake shoe until the lost parts of thesa-id draw rod is taken up, substantially as hereinbefore described.
