FILLING-SUPPLYING MECHANISM FOR AUTOMATIC FILLING-REPLENISHING LQOMS.

Specification of Letters Patent. Patented Oct.- 18, 1910.

Application filed March 26, 1910. Serial No. 551,618.

. Be it known that I, CHAR ES A. LITTLE: FIELD, a citizen of the United States, and resident of Lowell, county' of Middlesex, State of Massachusetts, have invented an Improvement in F illing-Suppl in Mechanism for Automatic Fillingep em'shing Looms, of which the following description,

v in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention has for its object the production of novel and improved mechanism for supplying filling in an automatic fillingreplenishing loom, providing for a large supply of spare filling-carriers and relievmg the weaver to a very-greatextent from labor connected with the-supply of filling.

In its 'essentialifeatures my present invention'comprehends a magazine arranged to sustain groups of filling-carriers; a rotary feeder to receive filling-carriers from such groups as the groups are directed from the magazine into discharging position; automatic mechanism to insertthe carriers of a group in the feeder; a transferrer to transfer the filling-carriers one by one from the feeder to. the shuttle, and means on the feeder to assume control automatically of the filling-end of each carrier as it is inserted in the feeder and to retain such control until transfer of such carrier to the working shuttle. Heretofore a ma azine has been devised to hold a large num er of filling-carriers and to conduct 'the carriers in 'a rotary feeder, "to be transferred therefrom to the shuttle, each filling-end being secured to "an end holder detachably mounted on the carrier, as in United States Patent No, 921,909 granted to M. L. Stone, May 18,1909, the structure therein set forth'having a device to detach the filling-end holders necessary in the patented stfiicture, ,inasmuch as the filling-carriers in the magazine are loosely held and are supported one upon another .in' upright compartments thereof, from which they travel individually into position to be inserted in the feeder.

Ithas also been proposed to mount groups of filling-carriers incages, each cage preferably holding several removable carriers, and

.being provided with a filling-end holder for each carrier, the cages being fed automatically step by step, and mechanism is .provided for transferring the carriers one by. one from a cage into weaving-position in the loom, as in United States Patent No. 843,107 granted to W; F. Roper,-February 5, 1907. The cages aresuperposed one upon the other in a suitable magazineifrom which they are fed into position for the transfer of the carriers held therein, and each fillingend is retained by its holder on the cage until the corresponding carrier has been inserted in the working shuttle. Thus there ISIIIO occasion for any change in the control of the filling-ends from the time the fillingcarriers, such as bobbins or cops, .are mserted in the cages until the carriers are transferred automatically to the shuttle, whereas in the Stone patent, supra, there must be a change the control of the ML .ing-ends, due to thestructure of the apparatus in general.

There are advantages attendant upon the use of cages each to receive a plurality of filling-carriers, as the carriers are held firmly and separatel until discharged from the cage, and the filling end holders on a cage are desirable, the. cages being loaded by unskilled l'abor in any convenient part of the mill, W There are also. advantagesin the use of a rotary feeder fonthe carriers, supplied automatically with filling-carriers from a reserve supplyin a magazine, as in the Stone patented apparatus, but the-removal of the filling-end holders from the filling-carriers, and subsequent care ofj'the said holders, is in practice objectionable in some respects.

In my present invention 1' make use of cages each holding a group of filling-carriers and having holders for the filling-ends thereof, and these cages are sustained in a novel and convenient manner in a magazine, from which they are fed, into discharging position. When a cage is so positioned the carriers are removed therefrom one by one automatically and inserted in a rotary feeder similar to that shown in the Stone patent, but 'I have provided the feeder'with devices which catch the filling-ends and disengage them from the holders on the cage \shuttle. structure the advantageous features found as the carriers are removed therefrom.

'These devices retain control of the fillingends so caught and disengaged .until the corresponding filling-carriers have been transferred from the feeder to the working Thus I am enabled to utilize in one bodiment of my present invention applied thereto, one of the cages being shown in discharging position; Fig. 2 is a front elevation of the apparatus shown in Fig. l, a

magazine beingbroken out; Fig. 3 is a rear elevation of; oneof the cages, with a'plurality of filling-carriers held removably therein, and showing the filling-end holders onthe outer end of the cage; Fig. 4 is an enlarged transverse section of a cage, broken portion of the guideway leading from .the'

out between its ends, and taken on the line 4 .-'4.-, Fig. 5, showing also one of the endholders movable with the rotary feeder; Fig. 5 is an enlarged detail in side elevation of a portion of acagein discharging position, and two of the end-holders movable with the feeder, one of the latter being in readiness to catch and disengage a fillingend from its holder on the cage; Fig. 6 is a --detail front elevation of the means for retaining a cage in discharging posltion,

with the devicefor discharging the filling carriers from the cage and in'serting them in the rotary feeder, only aportion of the latter being shown, and the transferrer is omitted altogether to avoid confusion; Fig.

7 is a detail in top plan view of a part'of the mechanism shown in. Fig. 6, to be referred to; Fig. 8 is a detail in'plan view of the cage positioning means, showing its cooperation with the filling-carrier next to be discharged from the page, the latter being 'shown n transverse section, and the discharging device is shown in plan ready'to remove the filling-carrier from the cage and insert it in the rotary feeder.

The sparefilling-carriers are initially placed 'in suitab/lev holding devices termed I cages, one 'of which is shown separately In- Fig, 3, at A. Each cage is conveniently made as a skeleton or open, rectangular frame of plate metal, of greater length than height, one-end, as a, having at its inner face a series of seats a for the butts of a plurality of filling-carriers B, shown as bobbins having rings 1) around their butts, and of well known construction, and-a cross-bar 01* extended from the top to the bottom of the cage has seats a for the tips of the carriers;

In. each seata .is mounted a yielding latch, conveniently made as a bent spring a, 1g.

4, secured at one end to the closed end of the seat and arranged to press firmly against the tip of the carrier and hold it securely yet removably in the cage.

The filling-ends 6* are led from the carriers'over the seats'a to the end a of the cage, notched slightly at a, Fig. 5, to receive the filling-ends, which latter are drawn under and held by light spring clips or holders a one for each filling-end, and mounted on the outer face of the cage end a.- These filling-ends-holders are clearly shown in- Figs. 3, 4 and 5 and they need only be strong enough to retain their grip on the ends under ordinary-circumstances. I

-The top and bottom of each cage have deep notches a therein'opposite each other,

Fig. 3, at the back of the cage, and adjacent the cross-bar a said notches being alined with the tip portions of the filling-carriers, for a purpose to bedescribed hereinafter. 'A

second pairof deep notches a is made in the.

top and bottom of the cage substantially in alinement with the butts of the fillingcarriers B, as best shown in Fig. 3,and near theend' a a third but shallower pair of notches a are provided.

The cages are'sustamed in upright position in the magazine, and when in diScharging position, a filled cage when viewed from the rear of the loom appearing as shown in Fig. 3. Preferably round projections a a extend from the opposite ends of each cage at top and bottom thereof, and as shown in Fig. 1 the 'projections are midway between the front and rear edges of the frame constituting the cage. Supposing the cages to have been filled or loaded, they are then placed in the magazine, presently. tobe described. v

In the Northrop loom, an example of which is found in United. States Patent No. 529,940, November 27, 1894,21 starting shaft is provided, which shaft is'rocked to effect the operation of fill-ing-replenishin mechanlsm whenever replenishment of lling in the running shuttle isnecessary, due to the exhaustion, breakage, or substantial exhaustion of the filling in use. Such movement of the starting shaft causes a transferrer to transfer a freshfilling-carrier from the rotary feeder nto the shuttle, at thesame time ejecting therefrom the spent carrier, all in a. manner fam1l1 ar .to'those skilled in the art. In Figs. 1 and" 2 the transferrer C and notched dog D of such mechanism areshown, "the transferrer rocking on the fixed stud C and being retracted orlifted by a spring C", and "it is moved downward to transfer a filling-carrier from the feeder. tothe shuttle when the dog D is engaged and moved by the hunter D, Fig. 1, on the lay, all as in the Northrop type of loom. 1

The usual rotary filling-feeder of the Northrop loom is used herein, comprising essentially connected disks E, E, shown in part in Fig. 6, and it is constructed and operated in the usual manner, the disks rotating on brace the horizontal arm E at its inner and outer -ends,. respectively, Fig. 1, upright standards'F being rigidlysecured to the rear ends of the members F, Fig. 1. The bracket hubs are fixedly secured to said arm E", the

inner bracket F being-located close to the inner face of the feeder stand E At the front ends of the bottom members F are rigidly attached upright standards F which extend above and depend below the members F, and theopposite inner faces thereof are longitudinally grooved or channeled, as at f,fr0m top to bottom, to consti tute a guideway as well as form the front of the magazine.

Each groove is widened-at its upper end and its rear wall curved, as at f, see

dotted lines Fig. 1, to coincide with the upper surfaces of opposite ledges f extending from the inner faces of' lates F connecting the upper ends of the ront and rear standards F said ledges being inclined downward and frontward and constituting supports for the upper ends of the cagesA when inserted in the magazine. The plates 'F project above the ledges or su ports f as'shown in Figs. 1 and 2, to orm side guards therefor. A second pair of inclined supports F Fig. 1, are'located below the pair f?, and in parallelism therewith, at such a distance therefrom that when-a cage A is placed in the magazine from its open back the projections a will rest upon the upper supports f sus nding the cage in upright posltion, and t e lower projections "(1. will just touch the lower supports F The rear walls of the groovesare cutaway just above the front ends 0 the supports F and the .tops of the latter are curved, at f, Fig. 1, to meetthe rear walls of the groove below said supports, to enable the projections a" of a cageto travel from said supports into the upright guideway,

the projections a of the cage traveling 1n similar manner from the upper pair of s11 ports f over the curved part. f into t e upper end of the guideway formed by the opposite grooves f. i

The filled cagesare placed in the maga- [zine one after another and slide forward along the supports, the leading or front cage passing into the -guideway and descending therein by gravity into dischargingposition, and afterone cage completely clears the magazine the next one will enter the guideway, as shown in Fig. 1. such time the upper projections a of the lower cage engage the lower projections 0a of the cage next above and support such cage, in an obvious manner, the remaining cages being held in the magazine by the cage in theupper part of the guideway.

to contain a'suflicient number of cages for for any other quantity desired, it being designed that the magazines will be filled each day'when work begins, by employees other than the weavers.

As shown in Fig. 1 the lower portion of rotary feeder and substantially tangent thereto, so that when a cage descends in such guideway the open seats forthe fillingcarri'ers therein face the feeder.-

Positioning means.The cage must be positioned for the discharge of the filling-carriers one by one, and after a carrier is ,discharged the cage must be permitted to descend in the guideway far enough to bring the next remaining carrier into discharging position. i

Referring to Figs. 1, 2, 6 and 8, the stud C has fixed thereon an upturned and rearwardly inclined T shaped arm G, located between the feeder 'plates E, E and provided with rigid, frontwardly extended fingers g,

path of the butts and tips; respectively, of the filling-carriers contained in a cage. The finger g clears'the top and bottom of the cage by virtue of the notches a", previously erses the notches a so that there is no engagementbetweenthe fingers and a cage at any time. When a cage descends in the therein is engaged and stopped by the fingers g, g in position to be discharged from the cage and inserted in the, feeder, and during such movement the rings 6 of the edge of finger 9 while the tip of the carrier As the feeder rotates in the direction of arrow 100, Fig. 1, each carrier inserted in the feeder is carriedupward and away from the positioning members as the feeder rotates, and when the inserting device isretracted therein into engagement with and. to be stopped the positioning members or fingers g, 9 and 1n like manner the cage-descends intermittingly until the carriers have The magazine can be made large enough.

, all been discharged, whereupon the empty cage drops from the bottom of the guideway,

The inserting mechanism is herein shown as an arm H rocking on the inner end of -stud 0 adjacent the feeder stand E fsee Fig. 6, and retracted by a spring H", said arm bein equipped with appropriate parts h, k whlch act respectively upon'the butt and tip of the filling-carrier during its dis- The operation of such parts is very similar to'the operation of corresponding parts of the usual Northrop transferrer, as will be apparent from an inspection of Fig. 8. A lateral extension H from the foot of the inserter H is located in front of the depending arm C on the transferrer hub, and when the transferrer C is. operated to transfer a filling-carrier from the feeder to the working shuttle the inserter is operated to discharge a carrier from the cageand insert it in the feeder. Thissupplying of the feeder with a filling-carrier each time a carrier is transferred therefrom to the shuttle is effected in the Stone apparatus before referred to, andasthereln Iprovided for the elongated upper edge of t e part h of the inserting devlce engages the next filling-car-j rier abov'e ituntil-sai device returns to normal position. Herein upon such return the cage drops one step to bring such previously -engaged carrier into discharging position, members g, 9

resting upon and stopped by t e positioning Means for controlling the fillingends.-

As the filling-ends are primarily held by I the holders on the cages it is necessary to assume control of such fillin -ends when the To this end the tip-supportln plate E of the feeder has suitably connecte, with it the elongated hub'M of a disk M, located at some distance beyond the outer face of the disk E, as

- shown in Fig. 1, the hub M turning on the arm or' fixed shaft E".

- p The'di'sk M isradially slotted at M, Figs}- 1 and 5, the slots corres onding in number with the total number 0 supporting devices for filling-carriers on the feeder, and a peripheral oove "m, is formed-in the outer face of sald disk, Figs. 4 and 5. A series of filling-end holders are mounted 'on the. disk, each holder being conveniently made of.re1-

atively stiff spring wire. Each holder comprises a straight shank m secured at its bent laterally into a substantially U-shaped innerend to the disk at m Fi 1, and extendedradially along the mid e of a slot M tothe outer end thereof, whereat it is portion m projectingbeyond the inner face of disk M, Figs. 2 and 4, and then the holder 1s agaln bent to extend radially across the outer face of the peripheralpart of the disk,

as at m. The extremity of the holder is i for the catchers, as indicate in Fig. 4. Referring to Fig. 5 the dotted circle B indicates the last filling-carrier which has \i been discharged from cage A and inserted and bottom of a cage providin a clearance in the feeder, the latter having advanced one .step after such insertion and the cage 'A has dropped one step to bring the next carrier B into discharging position. It

will Joe-seen that the filling-end 12 of that carrier is now just above the lower one of the .two catchers m andwhen carrier B 9 is inserted in the feeder itsfilling-end will occupy substantially the position shown by the'dotted line leading to the sniall er of the two dotted circles B Afters ch'insertion the discharging device H and its parts is retracted and the feeder advances one step in the direction of arrow 100, thereby causing the lower one of the two catchers m shown in Fig. 5 to' catch or engage the fill-' ing-end 6 and draw it down into the groove m, where it is firmly held by; the

part ha of the holder, and at the same time the filling-end will be disengaged from or pulled out of the holder don the cage, such holders being made of less holding power than the holders on the disk M. Thus the insertion of each filling-carrier into the rotary feeder from the cage'places its 'fillingend in position to be caught by the holder .mbvable with the feeder, and the subsequent advance" of the latter causes the proper holder on the feeder to assume control of the filling-end of the carrier last inserted and to disengage it from the holder on the -tive carriers are transferred from the feeder to the shuttle by the usual transferrer C, and it will be understood that the length'of ,filling from the disk M to the. cloth will be commonly employed in connection with Northrop looms. Such severed ends hang down-'fromthe holders on disk M until they threads by an automatic device comprising -"afsegmental plate 75 located adjacent the inner face of the disk M and normally just clearing the bends m Fig. 2, the plate being mounted on arod 76 mounted to slide longitudinally in separated bearings 77 Fig.

cage. The holders on the feeder maintain, control of the filling-ends until their respec- 7 severed by any usual thread-cutting devicespass beyond the transferring point, after which the holders are caused to release the 6, on a bracket 78 fixedlymounted on the outer end of the transferrer stud C. A pin 79 on the rod moves in a slot 80 in one of thebearings, to prevent turning of said rod, the latter;v having fast upon it a collar 81 acted upon by a spring 82 between the bearings, the spring serving to laterally position the segmental plate and rod as shown in Figs. 2 and 6. The inner endof rod 76 is beveled at 83 to cooperate with a cam lug 84 on the hub of the transfe'rrer C,

as shown in Figs. 6 and 7.

and the ends m are temporarily lifted out of the groove m in the disk M, thus releasing the ends of filling and permitting them to drop to the floor. WVhen the transferrer resumes its normal position the spring 82 retracts plate 7 5 and the bends m return to normal position, restoring the holders to active condition, the holders being rendered inoperative successively as the feeder rotates.

By making the plate 75 long enough to act upon several of the bends m at each transferring operation it will be manifest that each holder is opened or rendered in- 1 operative a plurality of times, so that there is no possibility of the ends of filling being retained unduly by the holders. I

In Figs. 1 and 2 I have not shown the filling-ends held by the several holders movable with the feeder, as the illustration of the mechanism would be confused thereby, the showing in the larger detail View, Fig. 5, being deemed sufiicient for a proper understanding of this feature.

As the operation of the apparatus has been explained from time to time through- .out the preceding description no further explanation is believed necessary to enable the operation of the various instrumentalities to be fully andclearly understood.

Narious changes or modifications in details of construction and arrangement may be made by those skilled in the art'without departing from the spirit and scope of my invention as set forth in the claims annexed hereto. v
