CHENILLE-MACHINE.

To all whom it may concern Be it known vthat I, CHARLES WIEBKE, a. citizen of the United States, residing at Newark, in the county `ofEssex and State have invented certain Vnew anduseful Improvements in Chenille-Machines, of which: the following is a specification,- reference' being had therein to the accompanying drawings, forming part thereof. Y

My invention relates to chenille machines and particularly tomachines for making ruil", or uncut chenille.' j l Objects of invention` are ysimplicity and compactness of construction, time and of man1pulation'- and other objectsf andad-z labor-saving convenience and operation, vantages whichwill hereinafter appear.-

In a machine having a pluralit 4 of sets 'of loop-forming pins and feed-regu at'ingrollers cooperative ,therewith, for concurrently making a corresponding plurality of lengths my invention includes means for independently vvarying the cooperative of chenille,

relationship of the feed-regulating rollers and loop-forming pins of the different sets of chenille-forming mechanisms. Y

Heretofore in common practice all of a plurality of feed-regulating rollers for all of the' correspondingl number of loop-forining pins have been carried by a single or common shaft extending entirely across the machine and mounted in bearing brackets adjustable onl the frame of the machine. This prior arrangement necessitates the simultaneous adjustment and a similar relationship of parts in all of the chenilleproducing mechanisms embodied in a m chine and precludes the possibilit-y of maliing chenille of different sizes er of different varieties as to texture vin the different lengths thereof made concurrently or of using different kinds or sizes of material in making the different lengths of chenille, but requires absolute unvarying uniformity in both material. and product for all of the lengths of chenille made at the same time.

It is to be noted that my invention, in the improvements above noted, entirelyI overcomes allfthese defects, permitting, among other advantages, the use of loop-forming pins of different diameters for the different lengths of chenille.

,My invention also includes means for rewinding the bobbins which supply surface thread to the fliers While such bobbins are v 'Specification of Letters Patent.

Application led November i1, 1912.

in the thread-supplying chine. havehad to be removed from the threadsupplying position-necessitating the removal of the fliers alsoand transferred for rewinding or replenishing to a separate winding mechanism mounted on the side of or over the machine, such inachinestaking up additional space because of the projecting winding' mechanism. Bymy present invention, this separate winding mechanism is eliminated, the entire machine is rendered more compact, and the refilling of the bobbiiis is greatly facilitated.

/Iy invention also includes other features of construction and combinations of parts, is will appear from the following descripion. I shall now describe the chenille machine illustrated in the accompanying drawings position on the maembodying my invention and shall thereafter point out my invention in claims.

Fig. 7 is a partial vertical section on a plane indicated by the line 7*7 of Fig. 6. Fig. Slis a further enlarged vertical section on a plane indicated by the line 8--8 ofFig.' 7. Fig. 9 is an enlarged longitudinal View of a short piece of the completed uncut chenille.

The chenille machine illustrated in the drawings as embodying my present invention` is adapted to produce onlyuncut chenille, known also to the trade as ruff and as frill, and is a double machine, having a duplication of parts for lengths of chenille at the same time. In each of the chenille-formingmechanisms of this machine, a stationary arbor l, firmly fixed at its rear end in a supporting standard 2, removably carr-ies'a stationary loopforming pin, such as 3 or 3*, at its enlarged forward end and in its middle portion serves as a bearing for the sleeve 4 o f a flier having arms 5. The enlarged shank ofthe loopproducing two forming pin, which enters the enlarged terminal portion of the bo-re of the arbor 1, is grooved (Fig. 7) for the passage of the primary binder thread a, whloh is sup lied along the surface of the projecting oopforming portion of the pin 3 (or 3*) through the' hollow arborl from a spool 6 at the rear of the machine. Loop-forming pins having loop-forming portions of either larger or smaller diameter (the

pins

3 and 3* being examples of two sizes) may be interchange- ,ably substituted in the arbor 1 of either of the vchenille-producing mechanisms for producing chenille having correspondingl, Elonger o-r shorter surface loops, as desired, i a machine embodying my resent invention b ]ceing particularly adapted to permit such substitution of loop-forming pins, as hereinc' before mentioned' and as will hereinafter regulating slight, circumferential Each more particularly appear. The loo -forming surface thread o is wound about t Vce loop# forming portion of the pin 3, and at the same time about the rimary binder thread a, by the arms 5 of 't 1e rotating flier (only one of these arms being used at a time, the other edecting rotary counterbalancing), the surface thread c being supplied to the flier from a bobbin 7 journaled on .the sleeve 4 ofthe flier. The secondary binder thread b is supplied along theloop-forming portion of the pin 3, at the outside ofthe coils of the surface thread A0by a metal feedroller 8 which is driven and controls the coils of the surface thread 0 in their movement forwardand from the pin 3 to form the surface loops-vbthenuncut chenille, the feed-regulating roller 8 having a roove to guide the thread b which'is supp ied from a spool 9 at the front of the machine, the thread b passing around an intermediate tension pulley 1,0. The' feed-regulatinOY-roller 8 is also milled or provided withi-` fine longitudinal striationsvas is usual so'it can eii'ectively vperform its coil-controlling.,operation.` My r invention involves the means for mounting and drivingvthe feed-regulating rollers 8 and means for rewinding the bob- "bins 7 with thread whilefthe bobbins .are in position on the sleevesi of the fliers.

feed-regulating roller 8 is mounted to `yield bodily away from the loop-forming passage of

lumps pin

3, or 3*', to permit the Each feed-reguor knots in the` material.

for independently varying its coperative lrelationsl'iip withthe loop-,forming pin, to provide for the use of diderent lsizes of yarn or thread andffor the employment of looplatingl `roller is "also provided with meansmeans of a thumb screw 14 passing loosely i through the top of the post and ypassing vertically through and having screw-thread ed engagement with the blocjk :12.

block 12 1s provided with a lateral guide flange, as` shown ink the drawings, on its side adjacent to the feed-regulating roller 8, but at the oppositesidefof the post 13 a loose washer 15 is carried by a stud 16 which rigidly projects from the block 12, a strong coiled spring 17 being interposed between an adjusting nut'screW-threaded on the stud 16 and the washer 15. Thehole at the top of the post 13 for the free passage of the screw- .14 is laterally enlarged at the side adjacent to the roller 8 (Flg. 4), and the head of thenscrev;7 slidably bears on the top of the post. When any abnormal pres- ,sure comes on the feed-regulating-roller 8,

material, the spring 17 will yield lto permit a downwardl angular bodily movement of the feed-regu ating roller 8, thereby permitting the lum or other enlargement to pass without trouble. To provide for using different lsizes of yarn or for employing loo forming pins of diiferent diameters, t e feed-regulating roller 8 may be raised or lowered by manipulating the screw 14.

All o f the feed-regulatingrollers 8 (being two in number in the machine illustrated in the drawings) are driven from a single common cross-shaft '18. Each feed-regulating roller 8 is separately driven by a train of three intermeshing

gearsl

19, 2O and 21, of

18, the gear 21 is carried by a boss or sleeve the middle gear 2() is an idler carried by the pintle 22 of pivoted ,elbow-

links

23 and 24 fulcrumed, respectively, on the cross-shaft 18 and the short roller-supporting shaft 11, the pintle 22 Abeing rigidly fixed in 4one of these links, such as in the linkY 23r- This arrangement of gears permits the adjustment of the feed-regulating roller,herein before described, without affecting the driving thereof.

cross-shaft 18 are a counter-shaft 25 andi cone pulleys 26 and 27 connected by a crossed belt 2 8, the counter-shaft 25 being driven by a sprocket chain 29 from a main shaft 30, the latter being provided with a fast pulley or ,driving pulley and a loosepulley 32, as is usual.

pulley 31 through the intermediary of a longitudinal shaft 33 geared to the main shaft 30 and connected by a sprocket chain 34 with an upper longitudinal stub shaft`35,

such as by reason of a lump or knot in the l forming an extension fromthe roller 8,'and v The means shown for drivingthe-commolr During the chenille forming..operation,N the fliers 4 5 areJ actuated from the driving,-

tively, on the sleeves 4 of the two adjacent fliers. The direction of rotation of the fliers positions, or in the middle when viewed from the front of the machine is counter-clockwise, as indicated by arrows in Fig. 3. The surface thread c causes the bobbins 7 to rotate in the same direction as the fliers, but somewhat faster, due to the usingI of t-he thread from the bobbins. The rotation of the bobbins 7 is controlled by a Weighted brake co-rd 38 engaging V-grooves in the rear rims or flanges of the bobbins, as is common in the art.

The mechanism for rewinding the bobbins 7 is actuated from the `loose pulley 32. A belt 39 connects the loose pulley 32 with a winding shaft 40 journaled on the lower part of the frame and carrying a V-pulley 41. A lever 42 is on the frame of the machine for movementtransverselyl of the machine and projects above the machine by` the hand. Near its pivotal point the lever 42 has a small idler guide pulley 43 mounted thereon, and adjacent to the rear rims of the bobbins 7 the lever 42- carries a small pulley 44 whose axis is parallel ywith the axes of the bobbins 7 and whose periphery is provided with a shallow belt-groove. A round or cylindrical Winding belt 45 runs over the V-pulley 41 on the winding shaft 40 and, being ided at an intermediate point at one sideu by the guide vpulley 43, passes upward over the small pulley 44, and projects from the shallow roove therein in proximity to the V-groovec rear rims of the bobbins 7, but out of contact therewith when the lever 42 is in its middle position, as shown in the drawings. When the usual main driving belt 46 is shipped to the loose pulley 82, thereby stopping the chenilleforming operation of the machine, including the stoppage of the fliers 4-,-5 and the feedregulating rollers 8; to one side, the winding belt 45 at the point where it passes over the small pulley 44 will be brought grooved rim of the corresponding bobbin 7 to effect its rewinding lwith a supply of surface thread 0,' and if the lever 42 be pulled to the other side, the other bobbin 7 will in like manner be rewound. The lever 42 may be locked in either' of these bobbin-winding non-operative position shown in the drawings, by means of a clamp 47 controlled by a clamp bolt having a wing nut 48 to grip a strap 49 forming also a gear cover. The thread-replenishing rotation of the bobbins 7 will be in a clockwise direction as viewed from the front -of the machine and as indicated by the arrow on the small pulley 44 (Fig. 3), the bobbins, of course, rotating oppositely to this pulley.

To equalize the braking effect on the bobbins 7 in the chenille-producing operation,

pivoted at its lower end in aposition to be graspedif the lever 42 be pulled into contact with the peripherally the brake. cord .BSshould be anchored ata point between thebobbins 7, and inthe ma- 1,

chine illustrated ,itis shown as anchored to a stud carried bythe lever 42, this point of anchorage of theV cord being merely incidental and a matter of convenience of construction. 1

Lubrication of'each iier and its bobbin, while protecting the threads or yarns, is provided for by means of a. thread-guiding tube or bushing 50 (Fig. 7), having enlarged end portions which have a fluid-tight fit inthe bore of the arbor l, but in its and throughout most of its length being of smaller external diameter than the internal diameter of the bore of the arbor, so as to thereby provide an annular oil space. On its upper side at a readily accessible point, shown as near its rear end, the arbor is provided vwith an oil inlet opening into the annular-oil space. Within the flier sleeve 4 the arbor 1 is shownas provided with oil outlets for-.lubricating such sleeve, the latter also being provided with oil passages or perforations adapted to register or communicate with the oil outlets in the arbor 1 for lubricating the bobbin 7 which covers the oil passages in the sleeve 4. Both theprimary binder thread a, passing. through the' arbor l, and the surface thread c, carried by the bobbin 7, are by means of this construction completely protected from the oil used for lubricating the flier and bobbin.

T e tension pulleys 10 that control the feed of the secondary binder thread b are fixed on a transverse shaft 51 driven at the proper rate by means of a gear 52 and intermediary idler pinion 53 from the feed shaft 18' for the feed-regulating rollers 8. The transverse shaft 51 also carries a conepulmiddle portion ley 54 for propelling the usual trolley employed to carry away the lengths of chenille as fast as formed. A large cone pulley 55, shown in the drawings as mounted on a counter-shaft 56 driven from the main shaft 30 by means of a sprocket chain 57, is for driving the usual twisting spindle ofthe trolle which twists the chenille to bring out the surface loops formed from the surface thread c and to bind'these loops between the bind," threads a and b.

A few of the more prominent advantages of -the hereinbefore Vdescribed machine embodying my invention will be briefly noted.

For each chenille-forming mechanismdifferent sizes and kinds of yarn or thread may be used andtalso different sizes of loop-forming pins may be employed to produce correspondingly different sizes and textures of chenille by the operation of each chenilleproducing mechanism, irrespective of the operation of any other chenille-producing mechanism in the machine. The bobbins carrying the loop-forming surface thread or yarn may be quickly refilled Without'thc usual,- necessity ofA having to remove vthem from their operative thread-supplying position on the fliers, and the fliers. and bob bins may be properly and safely lubricated -vvhile in theiry operative positions with the threads or yarns 1n place for producingv ms, a glinding a surface thread on the loop-forming pin, a separate feed-regulating roller cooperative With each loop-forming pin to control the movement of he coils of the surf-aceA thread therefrom, independent means for varying the coperative relationship of each feed-regulating roller and its loop-forming pin, the feed-regulating rollers.-

v 3. In a chenille machine, the combination of' a plurality of stationary loop-forming pins, a flier for Aeach loop-forming pin for Winding a surface thread on the loop-formflier for each loop-forming lpin forv and means foi` driving ing pin, means for supplying a primary binder thread to each loop -forming piu Within the coils of the surface thread, means for supplying a' secondar binder thread to each loop-forming pin a the outside of the coils of the surface thread, such latter means including for each loop forming pin a rigid surfaced yieldable feed regulating roller cooperative with the loop-forming pin for controlling the movement of the coils of the surface thread therefrom; means for each looplforming pin for independently varying the coperativerelationship of the feed-regulating roller and its loop-forming pin, and means for driving the feed-regulating rollers.

4. In a chenille machine, the combination of a rotative flier, a thread-carrying bobbin rotatively mounted co-aXially with the flier for supplying thread to the Hier, and mechanism :fon-,winding thread on the bobbin while the b'obbin is in the thread-supplying position relatively to the iier.
