EDWVARD Gr. \VOODS, OF MARGELLUS, NEW YORK AUTOMATIC STOP-MOTIONFOR FEEDING MECHANISMS OF CARDlNG-ENGINZS.

SPECIFICATION forming part of Letters Patent No. 329,425, dated October 27, 1885. Application filed June 2, 1385. Serial No.167,379. (No model.)

To aZZ whom, it may concern:

Be it known that I, EDWARD G. WooDs, of Marcellus, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Automatic Stop-Motions for Feeding Mechanisms of Carding-Engines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to automatic stopmotions applied to the well-known Apporleys Feeders, connected to the species of woolcarding machines designated condensers, and has more particularly reference to the apparatus shown in the Patent No. 62,917, granted to Ainsworth and lVright, March 19, 1867, of which this invention is a.- specific improvement.

My improvements consist in connecting the tripper to the reciprocating feed-carrier and arranging at opposite sides of the condenserframe levers adapted to be encountered and actuated by the tripper when allowed to assume its normal position by the breakage of the roving, said levers communicating with the catch which holds the shifter for throwing in and out of gear the actuating mechanism of the condenser, and when actuated by the tripper, as aforesaid, the levers release the catch, and thereby allow the shifter to throw the actuating mechanism of the condenser in gear, said combination and arrangement of devices causing a stoppage of the machine automatically with the breakage of the roving during the travel of the feed-carrier toward either side of the feed-bed, whereas in the hereinbefore-referred-to prior devices the feed-carrier was allowed to travel twice the width of the feed-table before tripping the catch which holds the actuating mechanism of the machine in gear.

My invention also consists in an improved construction and combination of the component parts of the automatic stop-motion, all as hereinafter more fully described, and specifically set forth in the claims.

In the annexed drawings, Figure I is a perspective view of that part of the finisher or condenser to which the Apperleys feeder is applied. Fig. II is an enlarged front view of the said feeder and my invention connected therewith. Fig. III is a plan view of the same, taken below the line m a: in Fig. II, and Fig. IV is a vertical transverse section on line 3 y, Fig. II.

Similar letters of reference indicate corresponding parts.

A represents the so-called finisher or condenser employed in connection with wool-carding machines, similar to that shown in the patent to Ainsworth and \Vright, hereinbefore referred to. B denotes the reciprocating feed-carrier of the well-known Apperleys feeder, for which Apperley and Olissold have obtained Letters Patent of the United States No. 18,888, December 22, 1857, said feed-carrier B being mounted on the front end of the frame of the finisher A in the usual manner. The carrier B slides on a guide-rod, 1", extended across the feed-table of the finisher A, and is automatically carried alternately in opposite directions across the said feed-table by an endless belt, D, running on revolving pulleys G O, which are pivoted on opposite ends of the supporting-frame of the feed, and receive motion from one of the revolving shafts of the condenser A by gears, pulleys, and belt connections in the usual and well known manner, not necessary to be here illustrated. A spur, f, projecting from the beltD and into a vertical slot, h, in the carrier B, carries the latter along with the travel of the belt. A pivoted catch, 9, at each end of the feed-frame holds the roving down upon the feed-table, while the carrier B travels across to the opposite side of the said table and deposits upon the table the succeeding lap or layer of roving. On a horizontal extension of the base of the carrier B, and reaching under the belt D, are pivoted two rollers, a a, between which the roving passes. The carrier B carries a tripping-arm, e,which is pivoted on a bracket, t, attached to the carrier B. One end of the tripping-arm reaches under the aforesaid carrier and toward the rollers n n, so as to lie in the passage of the roving and be traversed by the same, the pressure of the roving serving to depress said end of the arm 0. The opposite end of the tripping-arm c is weighted, so as to cause it to automatically tilt the arm so soon as it is released from the aforesaid pressure of the roving; hence said action of the arm ICO , c is produced in case the roving becomes disrupted. At opposite sides of the frame of the condenser A are pivoted two levers, c 0, each of which has one of its arms so arranged as to be encountered by the approaching trippingarm 6 when released from the pressure of the roving and tilted into its normal position by the weighted end of said arm, and to allow the tripping-arm to pass freely over said leverarms when the former is tilted into its abnormal positionby the pressure of the roving, as hereinbefore described. By means of springs to u the levers a c are held yieldingly in their described position. The leverchas connected to it a catchfb, which engages the shifter by which the actuating mechanism of the machine is thrown-in and out of gear. Said shifter may in some machines consist of a lever for moving a clutch, or other well-known and equivalent devices for connecting and disconnecting actuating mechanisms. In this case said shifter consists of the lever S, arranged to throw the driving-belt of the cardficylinder from the drivingpulley onto the loose pulley, the catch 12 aforesaid being provided with a notch, o, by which it interlocks with the lever S, and when so interlocked it holds the lever in position for maintaining the belt on the drivingpulley; otherwise the lever S is held normally in position for holding the belt on the loose pulley or for throwing the actuating mechanism of .the machine out of gear by a suitable spring, a, drawing or pressing said lever in said position. To another arm of the lever c is connected a rod or push-bar, d, by which it engages a secondary arm on the lever 0-, and when actuated by the collision of the tripping-arm e the lever c transmits motion to the lever c by the aforesaid rod d, so as to throw the catch b out of engagement with the belt-shifting lever S, and thus allowthe spring a to throw said lever in position for carrying the driving-belt onto the loose pulley. The same effect is produced by the collision of the tripping-lever c with the lever c. a

From the foregoing description it will be observed that the tripper eisheld in abnormal position and allowed to travel freely back and forth with the feed-carrier B so long as the roving passes over it; but so soon as the roving is severed and its passage to the feed ceases,

the tripper falls into its normal position and is caused to collide with one of the levers c 0, either of which throws the catch 1) out of engagement with the shifting-lever S, which is then immediately thrown by the spring a into position for carrying the driving-belt onto the loose pulley, and consequently the motion of the machine is stopped automatically with the severing of the roving passing to the machine.

The stop-motions heretofore employed on wool-carding machines were only connected with the actuating mechanism of the feed of the machine, and did not affect the operation of the card cylinder; hence in case of the breakage of the roving or sliver it was necessary to immediately reunite the sa'me,and if thiswas neglected the card-cylinder would run empty and produce an almost irreparable breakage of the condensed roving on the the pathof the tripper e, and providing said levers with means for transmitting motion to the catch 6, the stoppage of the machine is effected during the travel of the feed-carrier toward either side of the feed-table, and consequently more quickly than by the prior devlces.

Having described my invention,what1 claim as new, and desire to secure by Letters Patent, is-

'1. In combination with the actuating mechanism of the condenser, and the reciprocating feed-carrier, and mechanism for automatically moving said feed-carrier, as described, a shifter held normally in position for holding said actuating mechanism out of gear, a catch for holding the shifter in its abnormal position, a lever pivoted at one side of the condenser-frame:

and connected with the aforesaid catch, a lever pivoted at the opposite side of the aforesaid frame, a rod extending from lever to lever, and a tripping-arm carried on the feed-car- I rier and normally in position toactuate the aforesaid levers, and arranged to be traversed by the roving passing through the feed, and thereby held in abnormal position, substantially as described and shown.

2. The combination, with the driving-belt,

of the condenser A and the reciprocating feedcarrier B, and mechanism for automatically moving said feed-carrier, as described, of the belt-shifter S, the spring a, for throwing the belt-shifter to carry the belt onto the loose pulley, the catch b, for holding the belt-shifter to maintain the belt on the driving-pulley, the lever a, connected to said catch and arranged at one end of the path of the feed-carrier B, the

lever c at the opposite end of the path, the rod d, for transmitting motion from the lever c to the lever c, and the pivoted arm 6, carried on the feed-carrier, and having one end weighted to depress it into position for colliding with the levers c c, and the opposite end in the feed-passage to receive the pressure of the roving passing through said passage, and thereby become tilted to clear the aforesaid levers, substantially in the manner specified and shown.

3. In combination with the frame of the condenser, driving-belt of the card-cylinder, reciprocating feed-carrier B, and mechanism for moving said feed-carrier, as described, a spring-actuated belt-shifter arranged to hold said driving-belt on the loose pulley, a catch for holding the belt-shifter on the-drivingpulley, a lever pivoted on the frame and connected with the catch, and a tripper carried on the feed-carrier and normally in position to actuate the aforesaid lever, and arranged to be traversed by the roving, and thereby held in abnormal position, the whole com- 5 bined and arranged to stop the motion of the cardcylinder automatically with the breakage of the roving, substantially as set forth.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the 10 county of Onondaga, in the State of New York, this 18th day of April, 1885.
