BUNCH-BUILDER MECHANISM.
Application filed February 26, 1925.. Serial No. 11,668.
To all whom it may concern: Be it known that I, JEssE humans, a citi- -zen of the United States, and a resident of Uxbridge, in the county of Worcester and Commonwealth of Massachusetts, have in vented certain new and useful Improvements in Bunch-Builder Mechanisms, of which the following is a specification.
This invention relates to spinning and winding machines and particularly to machines which are provided with bunch builder mechanisms of the type shown in United States Patent to McVey No.-1,491,- 808, dated Apr. 29, 1924. The bunch builder mechanism shown in this patent comprises one or more lug cams mounted on the rotating builder cam,a locking latch swingable on a stationary part of the machine, a knock-off roll cooperating with the lug cams,
an abutment member adjustably mounted on the lower end of "the latch and abutting the top of the builder lever thus holding the traverse of the ring rail stationary for a short period of time during which the The rotation of the builder cam brings one of the lug cams into contact with the knock-roll thus releasing the latch from its abutting relation with the builder lever and the main wind of the yarn follows. It has been found in practice that this construction is objectionable in that it cannot always be depended upon to form a bunch suhiciently large to perform the proper functions in the shuttles of weft replenshing looms. This is due to the fact that when the machine stops for dofling the rotation of the builder cam does not cease so as to leave the lug cams in any predetermined position, consequently when the machine starts on a new doif with the bunch building mechanism in operative position the lug cam may be so close to the knock-oft roll that the time taken from the starting of the machine to the knock-off action will be insufficient to form the yarn delivered into a proper sized bunch.
The object of the present invention is to, obviate the objectionable feature above noted and to generally improve the form and arrangement of .the knock-oft means, and to such end the present invention consists of the devices and combination of devices as hereinafter described and claimed.
The present invention is illustrated in the accompanying draw ngs, whe ei Figu l the knock-oft roll and a shows a perspective view of a sufficient portion of-aspinning machlne embodying the invention to make clear its construction and manner of operation. I Figure 2 is a rear elevation of the knock olf roll in itsinitial position on the locking latch when the latter is in abutting relation with the builder lever. v
Figure'S shows the knock-0E roll in its final position ready to release, the locking latch from its abuttting relationwith the builder lever through pressure exerted by the motion of the lug cam, the path of rotationof the latter being shown in dotted lines. Figure 4 is an enlarged side elevation of portion of the roll slide and locking latch.
Similar numerals of reference designate corresponding parts in the several figures.
The invention is herein illustrated as applied to a ring spinning machine, wherein the driving end 1 contains the usual gearing -(not shown) that transmits rotary motion to the builder cam2 of usual construction to which are fixed oneor more lug cams 3 which act'in conjunction with a knock-oft roll 4 rotatable on stud 5 fixed to slide 6 adjusta'bly mounted on locking latch 7 and firmly held in position thereon by the clamping bolts 8.
The locking latch 7 is swingable on stud 9 fixed in bracket 10 bolted to the end frame 1. At the lower end of the locking latch 7 a finger 11 is adjustably mounted which serves as an abutment to arrest the motion of the builder lever 12 while the bunch building mechanism is in operative position.
The knock-off roll 4 is formed with three lobes 13, 14 and 15 arranged approximately 120 degrees apart. Normally when the locking latch 7 is in an operative position the position of the knock-off roll is as shown in Figure 2 with lobe 13 projecting into the path of rotation of lug cam 3. The rotation of the builder cam 2 brings one of the lug cams8 into contact with the lobe 13 thus causing the roll 4 to swing to the position shown in Figure 3 with lobe 14 projecting into the path of rotation of the second lug cam which exerts a pressure. thereon causing the lobe 15 to abut against thespring plunger 16 supported in the bearing 17 integral with the slide 6. Further pressure on the lobe 14 carries the lobe 13, against the sto pin 18 fixedly connected to the slide 6 wi the result that the locking latch 7 is forced from its abutting position on the top of the builder lever 12, and the builder then re sumes its usual movements in operating the traversing of the ring rail for forming the main wind of the yarn on the "bobbins.
When the lobe 14 is free from contact with the lug cam the roll t is turned on its stud 5 to its initial operative position ready for the next doll by the pressure exerted on the lobe 15 by the spring plunger 16.
It is understood that my invention is adapted for use withbut one lugcam in conjunction with the builder cam, in which case 15 there would be a fu-ll'revolution ot the builder cam between the first andsecond move- {merits of the =knock-ofi roll.
Changes in form, proportion, size, and
minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages oft my invention.
I claim:
1. Bunch builder mechanism for .spinening machines comprising a builder lever, a rotary cam actuating said lever, one or more lug cams mounted upon and rotating in unison with the rotary cam, a locking 30 latch to arrest the motion of the builder lever during the winding of the bunch, .and
step by step". aneans cooperating with vthe latch whereby the latter is released from a locking relation with the builder lever after the bunch is wound.
2. Bunch builder mechanism for spinning machines comprising a builder lever, a retary cam actuating said lever, a plurality of lug cams mounted upon and rotating in unison with the rotary cam, a locking latch to arrest the motion of the builder lever during the winding of the bunch, a knock-oft roll rotatable on a stud fixed to the latch, three lobes on said roll two of which are adapted to intersect the path of rotation of the lug cams, an abutment member in a fixed rela tion with the locking latch and adapted to actin conjunction withthe knock-otl' roll to release the latch from its locking position with the builder lever and means to return the hock-oil roll to its initial operative position.
3. Bunch builder mechanism for spinning machines comprising a builder lever, a rotary cam actuating said lever, a ;plural ity of lug cams mounted upon and rotating in unison with 'the rotary cam, a. locking latch to arrest the motion of the builder lever during the winding of the bunch, an adjustably mounted slide on the latch, a knock-01f roll rotatable on a stud in a fixed relation to the slide, three lobes on said roll, two of which are adapted to intersect the path of rotation of the lug cams and the other as'an abutment cooperating with a pin in fixed relation with the latch and a spring actuated plunger abutting against a lobe of the knock-off roll effecting the return or" the roll to its initial operative :position.
In testimony whereof, I have signed this specification.
JESSE JEFFERS.
