STOP-MOTION FOR SPINNING-MACHINES.
SPECIFICATION forming part of Letters Patent N o. 774.,1 19, dated November 8, 1904.
Application filed August 12, 1903. Serial No 169,267. (No model.)
To all whom, it may concern:
Be it known that I, MANTON T. BENTLEY, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented a certain new and useful Stop-Motion for Spinning-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
In the working of silk or other yarns it is often necessary to double two or more continuous threads together in order to get a fin ished thread of the required size and construction. This is accomplished by passing the single threads from any number of spools required over properly constructed and arranged guides and bringing the same together on another spool or bobbin, termed the takeup bobbin, which may be revolved at the same time, thereby twisting the threads together. In order to insure a continuous thread from each of the primary spools, some means must be provided for stopping the motion of the take-up bobbin as well as all the other spools whenever a thread breaks or the spool runs empty, thereby giving the operator time to piece or tie up the broken ends, so that the spools may again be set in motion.
The object of the present invention is to provide simple, reliable, and effective mechanism for the purpose above described which is positive in action and which will enable the broken thread or threads to be reunited and themachine again put in operation.
With the above and other objects "in View, the nature of which will morefully appear as the description proceeds, the invention consists in the novel construction, combination,
and arrangement of parts, as hereinafter fully described, illustrated, and claimed.
In the accompanying drawings, Figure 1 is a vertical cross-section through a spinning or doubling machine, showing the present invention applied thereto.
cient to illustrate the nature and operationof the present invention.
Like reference-numerals deslgnate corre- Fig. 2 is a ,front, elevation of a portion of the machine sufii-,
pass over a carrier-bar 2 at or near the top of v the machine, the carrier-bar being supported by a bracket 3, in 'turn supported upon a post or standard 1, extending upward from the machine frame. The threads then pass through the eyes 5 of a series of fallerwires 6, pivotally mounted at 7 on the machineframe and provided adjacent to their pivotal points with oflset extensions forming tailpieces 8, which project rearwardly, as shown in Fig. 1, and lie immediately over, but normally out of contact with the upturned heel extensions 9 of a series of knock-off levers 10, which extend forward beneath the drive-roll 11. Each of the knock-01f levers 10 is provided adjacent to its outer end with a catch lip or shoulder 12, which is adapted to move into and out of engagement with one or more shoulders 13, formed on a trip-collar 14, fast on the shaft oraxle 15 of the drive-roll 11, as indicated by dotted lines in Fig. 1. In case the thread 1 breaks, the taller-wire 6 drops backward, bringing thetailpiece 8 into en:
gagement with the extension 9 of the knockofi lever. This rocks the lever 10 on its fulcrum, and being fulcrumed intermediate its ends the catch-lip 12 is moved upward into engagement with one of the shoulders 13 on the revolving trip-collar 141. In the rotation of the trip-collar, and by reason of'the engagementbetween the shoulders 12 and 13, the knockro filever is moved outward, thereby swingmgtheltrip-lever 16, upon the upper end or ,vvhich the knock-off lever is fulcrumed, as shown at 17. I
Theknock-ofi' lever 16 extends substantially in afvertical direction and is fulcrumed inter: mediate its ends at 18 on the machine-frame, while the upper arm of the lever is acted ward and keep a roller 20 at the lower end of said lever upon and in engagement with a foot or rest 21, forming an Lshaped extension of.
an arm 22, extending outward from a sleeve 23, mounted fast upon and movable with avertical reciprocatory rod 24. When the triplever 16 is vibrated by the means above described, so as to move the roller 20 out of engagement with the foot or rest 21, the liftrod 24 is released and at once moves upward by reason of the tension of an expansionspring 25, which is interposed between a shoulder or collar 26, fast on the lift-rod, and a bearing on the machine-frame, through which said lift-rod slides. At a suitable point the lift-rod 24 is provided with a laterallyeXtending tappet 28, which in the upward movement of the lift-rod comes in contact with and operates a shifter-lever 29. The lever 29 operates a slide 30, mounted on one of the machine-rails 31 and carrying a pair of beltguide pulleys 32, between which runs a driving-belt 33, which operates the spindles 34 of the take-up bobbins 35, upon which the thread. or threads 1 are wound. The belt-shifting device now being described is also equipped witha brake 36, more particularly described in a copending application, so'that when the slide 30 is moved by the lever 29 the drivingbelt 33 is shifted out of driving contact with the spindles 34, and at the same time brakeshoes are brought into contact with the spindles, thereby bringing the latter to a stop and stopping the winding of the thread upon the spindles.
37 designates the ring-rail of the machine, which moves up and down along the length of the bobbins 35, and 38 designates one of the travelers connected with the ring-rail and encircling the bobbin for distributing the thread thereon and guiding the same thereto.
Movable with the lift-rod 24 is a feed-roll lift-rod 39, the same being connected rigidly with the rod 24 by means of a coupling or bracket 40, of any suitable description. At its upper end the rod 39 is provided with a buffer-spring 40, which, as the rod 39 moves upward, is brought into contact with a portion of the feed-roll frame 41, the result being that the feed-roll 42 carried by said frame is raised out of contact with the driving-roll l1, and as the feed'roll 42 draws the threads from the primary spools it will be seen that the feed of the threads will be stopped as soon as said feed-roll is moved out of contact with the drive-roll. The threads or thread 1, after passing through the eyes of the faller-wires, are brought together by a gathering-guide 45, at the top of the feed-roll frame 41, and are wrapped once around the feed-roll 42 and then carried outward over a guide or carrier roll 43, thence downward through a guideeye 44, suitably supported on the machineframe, and from thence to the traveler 38 on the ring-rail 37, Where the compound thread is twisted and wound upon atake-up bobbin 35.
46 designates the foot-lever, which is connected at 47 with the lower end of the lift-rod 24. After mending the broken thread or threads the operator depresses the foot-lever 46, drawing down the foot piece or rest 21, so
that the trip-lever 16 may swing back to its normal position, carrying the roller 20 in engagement with the foot piece or rest 21, when the machine is again in readiness for operation.
In the operation of the machine when a thread breaks or a spool runs empty the fallerwire, through the eye of which the thread passes, is released and falls backward, bringing the tailpiece thereof in contact with the extension of the knock-off lever. This raises the opposite end of the lever and throws said lever into engagement with the shouldered collar on the shaft of the drive-roll, the latter acting to carry the knock-off lever forward. This has the effect of rocking the trip-lever and moving the roller 20 out of engagement with the foot or rest 21, thereby releasing the lift-rod 24, which is moved upward by the action of the spring 25. As the lift-rod moves upward it acts upon the shifter-lever 29, and thereby shifts the driving-belt out of engagement with the spindles and at the same time applies the brakes to the spindles, stopping the latter. In its upward movement the liftrod 24 also raises the feed-roll lift-rod 39 and swings the feed-roll frame and feed-roll upward, carrying the latter out of engagement with the drive-roll and stopping its revolution and the feed of the threads. The lift-rod 24 may carry any number of tappets for operating the different parts. The buffer-spring 40, at the upper end of the feed-roll lift-rod, relieves any sudden blow against the feed-roll frame when quickly released. In again starting the operator pieces or ties the broken ends, replaces the threads in the eye of the dropwire, thereby holding the latter in upright position, and otherwise properly places the thread, as previously explained. He then depresses the foot-lever 46, which carries the lift-rod 24 downward, compressing the spring 25, releasing the tappet 28 from the shifterlever 29, when by the action of the shifter slide-spring (shown at 48) the driving-belt 33 is carried back into driving engagement with the spindles. In the same downward movement of the lift-rod 24 the trip-lever foot or rest 21 is also depressed to enable the trip-lever spring 19 to force the trip-lever 16 and knock-off lever 10 back to their original positions. At the same time the feed-roll liftrod 39 is moved downward, dropping the feedroll 42 into engagement with the drive-roll, whereby it is again set in motion and the feed of the threads resumed.
It will be apparent that the construction hereinabove described is susceptible of various changes in the form, proportion, and minor details, which may be accordingly resorted to without departing from the principle or sacrificing any of the advantages of the invention.
Parts of the machine not hereinabove described may be constructed and arranged in any usual or preferred manner.
