SPEED-GONTROLLING DEVICE FOR RING-SPINNING FRAMES.
Specification of Letters Patent.
Patented Oct. 3, 1916.
Application filed August 1G, 1913. Serial No. 785,019.
To all whom t may concern Be it known that we, FRIEDRICH EICH- BERG, a subject of the Emperor of Austria- Hungar residing at Breslau, and IIER- MANN Amin, a subject Of the King Of Prussia, residing at Berlin, Germany, have invented Certain new and useful Improvements in Speed-Controlling Devices for Ring-Spinning Frames, of which the following is a specification.
This invention relates to electricallydriven ring spinning machinery, an its object is to gradually increase the speed at which the thread is wound upon the cop, so that the tension may be practically uniform at all parts of the bobbin.
It has been found that when the speed of the machine is uniform, the thread is wound too tightly upon the smaller diameter of the bobbin and too loosely upon its large portion. This difficulty increases as the bobbin builds up. In order to give a uniform tension, a variable speed has been given to the f machine by suitably controlling the electric motor which drives it. Our invention provides new and improved means for accomplishing this result.
The motor drives a shaft carrying a cam which rotates synchronously with the travel of the ring rail and .operates upon suitable controlling devices which regularly accelerate and lessen the speed of the motor, so that when the rail is down and operating on the bobbin the motor will run more slowly than when the rail is up and the thread is being laid upon the smaller In addition to this mechanism, we provide mechanism which slowly accelerates the mean speed of the motor. This idea is not broadly new with us, but our solution of the problem we recheap, reliable and durable, and for these reasons an improvement in the art.
Our inventionwill from ythe followingv taken in connection with drawings in which- Figure 1 isa sectional side elevation showing the essential elements of the invention;
Y l of the same; and
Fig. 3 is an edgewise elevation of the twin cams and the gearing. y The cam 1 is driven from the main shaft be better understood detailed description the accompanying ing device, such vthe machine,
of the spinning frame, and rotates synchrono usly with the rise and fall of the ring rail. It actuates at each revolution a lever 2, which is fulcrumed at 3. A flexible connection 4, such as a cord, band, chain, or the like, runs under a pulley 5 on the free end of the lever fulcrum, being led thence to the free'end of a lever 7 fulcrumed at 8, to which said flexible connection is made fast. The oscillation of the lever 2 by the cam 1 therefore causes the iieXible connection to be alternately pulled and slacked. The connection is attached to some suitable speed controller for the electric motor which drives the spinning frame, such as a rheostat arm, a rocker carrying the motor brushes, or the like, so that at each revolution the cam 1 causes the motor to speed up and slow down alternately.
The gradual acceleration accompanying the building up of the bobbin is effected by `two cams 9 and 1() operating upon a cross bar 11 on the lever 7. The cam 9 is loose on the shaft 12, but the cam 10 is secure fast thereto. A pinion 13 fast on said shaft 12 meshes with a spur or segment gear 14 whose shaft carries a long arm 15 working over a graduated quadrant 16. Theweight of the arm tends to swing it downward and thus turn the shaft 12 and actuate the cam 10.l This tendency tirely prevented by some kind of time-limitg as a dash-pot17 in which works a heavy plunger 18 whose stem 19 is pivotally connected to the arm 15 by a pin and slot joint 20. A locking device cooperates with the stem 19 to stop the descent of the arm and plunger when the spinning frame is stopped for any reason, as or instance to tie a broken thread. Such locking device may be a spring catch 21 engaging teeth 22 in the stem and 'adapted to be withdrawn from its operative position by an electromagnet 23 in circuit with the electric motor which operates the y machine. this motor circuit is opened to stop theelectromagnet will be deenergized and will release the catch which will automatically engage and lock the stem. lA pawl 24 on the loose cam 9 cooperates with a ratchet wheel 25 fast on the shaft 12 and causes the cam' A Y I 'cam l'until a trip 26disengages the pawl,

ti-011er.
whereupon some suitable device, such as a weight'27 attached to a cord wound on a drum 30 projecting from one side of the cam 9,-returns the cam 9 to its starting point, where Aa lug 2S on'said cani strikes a fixed stop 29. During the return of the cam 9 in this manner 'the pawl 24 'remains disengaged. n
The operation 'is as follows: Tlie'dashpot or other time-limiting device is set to let the arm 15 drop through its predetermined range in the time required to build up -a complete bobbin. As it moves slowly downward, it turns the gear 14 in a counand thus causes the cams`9 and 10 to rotate clockwise. At the 7 rests against the :cam 9, both cams having a depression at this point, as shown, but that in.cam l0 being the As the cai'ns'rotate, the lever 7 forced slowlyfto theleft, taking up the flexible connection l bit by bit 'though leaving .the lever 2V free to impart it normal oscillation to the -inotor-con- The taking up of the connection 4, however, slowly shifts the mean angular controller, so thatthe mean speedof the motor is vcorrespondingly in- `creased. andi the tensin on the threadlmaintained as the bobbinbuilds up, without interfering with the variation of the speed V'to `avoid variation of-tension in different pushed the portions of each layer of thread effected by the cani l.

The notch in the cam l0 will be angularly displaced from its originalposition, but as it is longer than the notch in the cam 9, the two will still register and permit the lever 7 to lean tothe right. The lever will be actuated just as before, to take up the predetermined amount of the flexible connection l, but the circular periphery of the cam l() will come into play sooner, laccording to the -intended length of the bobbin. 1t will be seen that the tivo cams vv9 and l0 are in effect an adalent to a large number of double notched cams with different angles between the notches, and that by suitable adjustment of these cams the spinning speed ca-n bevaried in many different ways.
