IMPROVEMENT IN FEED-REGULATOR EOE SPINNING MACHINES.

TQ ALL WHOM IT MAY :CONCERN:

Be it known that I, CHRISTOPHER Hunnsenasr, of Brooklyn, in the county of Kings, and State of New York, have invented a. certain nexv and useful-Improvement on Regulators to Jennies for Spinning Rope-Yarns, or other apparatus controlling the feed to the drawing-rolls of spinning frames, of which the following is a vfulhclear, and exact description, reference being had to the accompanying drawing, forming part of this specification, and in which- Figure l represents a plan of a` regulating apparatus constructed according to my improvement.

Figure-2, a sectional elevation of the same; and y t Figure 3 a sectional elevation of certain details used to carry out my inventionrdetached and taken `as 'indicated by the une a' e in ng. 2. y

Like letters indicate likel parts throughout the severa-l figures. l y p vThe nature of my invention consists in a combination, with suitable clutchmechanism under control of the dravving-rolls, of' wheels of different diameters arranged on a primary and secondary shaft, the one of which is hung loose on its shaft, and geared theterth bya pawl and ratchet to vary the velocity-given to the gill-bars, without stoppage or lost motion in making the changes te suit variationsin thickness of the sliver; and said invention also consists in a 4novel combinationV of fast and loose wheels, as described, with clutch levers so operated by the dra'wing-rolls-as that only the fast motion maybe put in gear, or both fast anu slow motions thrown out simultaneously bythe opening and closing of the drawing-rolls. y i

Referring to the accompanying drawing, A represents the drawing-rolls, geared together by pnions B,

driven by any suitable mechanism, and serving to pass the sliver from 4the gill-bars through orover the regulatorA to the yer. The one of these rolls A has its shaft hungin levers or arms hinged as at a, and carrying at their ,outer ends a rod, connected with a lowercross-ibanic. C is the running or cli-ivingfshaft of the regulator,

carrying, so as to rotate with it, clutches D D', that, when thrown'into action, `gear with-loose sliding clutches E E', having secured to them a wheel and pinion F F', which gear, the one (Wheel F) with a spur-wheel, G, fast to ansecondary shaft, H, and the other (pinion F) with aspur-wheel, G,1loose on said shaft, vbut geared therewith under certain circumstances, as hereinafter explained, by means of'a ratchet-Wheel, K, fast to the shaft H and spring-dog or pawl L, connected with the wheel G. This secondary shaftH serves by pulley and belt, or otherwise, to give motion to the gill-bars which feed the-material to the drawing-rolls. i When the wheel F is the driver t0 the spur-'wheel G, a comparatively rapid motion is given to the secondary shaft H, and of a consequence to the gill-bars, producing a fast feed of the sliver through the drawing-rolls to 'the iyer, which actions given on the sliver being thinner than it should be to pass to the iyor. y On the other hand, when the pinion .Ff is the ldriver-,of the shaft II through thewheel G', which'action occurs when the sliver is of. the proper thickness, then the motion to the gill-bars and feed through the drawing-rolls A is slower. By these means an Vc cluality of feed is established to the flyer, which regula-ting action is effected by the rise or fall, accordingV to the thickness of the passing sliver, Vof the drawing-roll or rolls, say the roll connected with-thc levers thatearry the rod b und cross-bare; said cross-bar acting upon pinsel (ZY, of arms e Vc,branehingfrom elutchleversI I',

-lthnt have a'tend'e'nc'y, bytmeans ofa connecting spring, J, to' throw the sliding clutches E Einto gear with the clutches D'D of the wheel and pinion F F', In ordinary action, that is, when the sliver passing through the drawing-rolls is of the proper thickness, the rolls are separated only tothe necessary extent to cause the crossbar c,whichiaets primarily on the vbar c `of the. clutch lever I, tothrow out of'gear the sliding clutch D with the clutch E of the wheel F. Under these-circumstances,'and there being no lift on the'pinid the lever 1 keeps inrgearthe-s'liding clutch D with the clutch E of thepinion-F, that accordingly'becoines the driver through thefwheel G of the feed-driving secondary shaft H. Should the sliver, however, passing through the drawingl rolls, be thinner or finer than is proper, then lift being taken off the pin d, the springJ causes the clutch'D to gear tvith the clutchE of the -vvlrcel F, which through. the wheel G becomes the driver of the secondary shaft H, by-ca`using it tor'un faster than the pinion F', and wheel Gr serves to operate it; the wheel G slipping on its shaftl by reason of 'itsconneetion therewith through the pawl L and ratchet-wheel K, said wheel, however, keeping in driving-gear through the pinion Ff', clutch E', 'and sliding clutch D",with the running or drivingshaft C, so that on a proper thickness of sliver again passing through 'the drawing-rolls, the speed of the gillbars and feed is slackened by lift on the arm e throwing the clutch E out of gear, and withoutstoppnge'or any lost motion the pinion F' made theV driver of the secondary or gill-har operating shaft at aslower velocity. This avoidance of any temporary stoppage or lost motion is highly important, and is secured by the gear of the pinion F' with the shaft, both when said pinion acts as the driver and when the wheel F is such, the gear of the wheel-G' with the shaft H by pawl and ratchet accomplishing this,-irr'espective of any special onprecise clutch gear, which may beas represented, and connected with the drawing-rolls as described, or otherwise, th'ese i.

latter means being capable of great variation. Onthe sliver passing through the drawing-rolls being'too thick or coarse for the flyer, or anything unusual occurring to unduly open said rolls, then the bar c is. caused to lift both upon the primary pin Z and 'secondary pin d', so as to throw both clutches D D' out of gear', which stops the motion of the secondary shaft I-I, and, as a consequence, of the gill-bars and feed tothe drawing-rollgand which gives an opportunity to remove the obstacle or rectify the feed What I claim as my invention, and desire to secure by Imtters Patent, is

i la The combination with a clutch or other mechanism, controlled by the drawing-rolls, and serving to throw in or out of gear-with the driving-shaft C, wheels or pinions F F' of the secondary orrgill-bar operating shaft ,H 'having gear G G', the one of which is eonnectedwith its shaft by pawl and 'ratchet L K, for operation in connection with the gear of the driving-snaft C, toV give afnst orslow motion to the Vgill-bars, substantially :1s specified.

v 2. The' combination of the fast wheel Gr and loose wheelG', with its pawl and ratchet L K, loose wheel and piniouF F', with their clutches E EQU) D', and clutch arms or levers I I', so arranged and operated by mechanism connected with the drawing-rolls as that the onelever may be acted upon in advance ot' the other, or both simultaneously, essentially as herein set forth.
