State of Massachusetts, have invented an` Improvement in Take-Up Mechanisms for Looms-'of which the following description, in connection with the accompanying drawings, is aspeciiication, like letters on the representing like parts.

relates to looms, and more particularly to z the cloth takefup mechanism land associated parts. Y

In the production of woven fabrics of uniform texture, it is desirable that a proper length of cloth be taken up following'each `pick in case filling is properly laid in the shed, but that on failure to lav filling that the take-up action be tem orarily suspended in order that thin places in the cloth may be avoided. When ythe loom is stopped for some causes, the loom tender often finds Yit desirable ,or necessary tomoye the lay '25 back and forth Without passing through that I cycle of its movement where the picking action occurs, :fnd should the take-up be ef fective at Such times objectionable defects are liable to occur in the'cloth, as well understood by those familiar with the art. On

theother hand, should the loom tender move the lay through thatportion of its cycle wherein the shuttle is picked, it is equally desirable that the take-up be properly actuated following such. pick, whether effected by hand or by the usual pick or shuttle motion. Likewise when the loom has been stopped for any cause, it maybe desir able to manipulate the take-up by hand.

I 'With these generally stated factsvin mind,

the aims and purposes of the present invention =will bestbe made clear from the following description of one form of means for carrying it int-practical effect, it.being understood that 'the invention is not confined to the details of the means shown but in its true scope is dcfinedpby the claims.

ln the drawings ;-Figure l is a front elevation of a loom embodying the present invention, parts being broken away and omitted; Fig. 2 is a longitudinal section of line 6 6, Fig. 5.. The loom frame, comprlsin upri hts 1 connected to'the la -the pitman I3-where y upon rotation of they crank shaft the lay has imparted thereto the enlarged sectional detail on the line 3 3, Fig. 2; Fig. 4 is a section on th`e line 1r-4, Fig. 3; Fig. 5 is a section longitudinally of the actuating shaft on theline 55, Fig. 3, showing the in moving sleeve land its mounting; and (ig. 6 is a section on the and -side 'fra-'mes 2, maybe o any esired character suitable .for sup orting theoperating parts, and is rovided with bearings 3 for a crank sha 4 havinga crank 5 6 by means, such as the loom on thevline 2, Fig.A 1; 3 is an usual reciprocating orback and forth mol 'i tion.

At eachend of the lay -are the usual `shuttle boxes 8 and 9, longitudinally of" which thepicker Sticks 10 and pickers 11,

respectively are adapted to be moyed to ,throw the shuttle from one tothe other Vbox by the usual actuating means, suchA as the picker shaft 12, Fig. 1, operate@ as usual from the picker cam13 on the camshaft 14 `Eig. 2 through suitableconnections 1 5', Fil'g. Lf Further escription in detail of the pic ing mechanism' is unnecessary, as such devices are well understood by those skilled" in the art,"and so fara's the present invention is concerned, suchmechanlsm may be as usual, except in Such respects as -may hereinafter appear.

' The cam shaft 14 may be driven from' any suitable or available source ofApowcr', but is herein shown as being actuated from the crank shaft 4 through the gears 16 and 17, the construction bein such that said shafts may he rotated in re ation to each other as two to one, that is the cam shaft 14 is caused to make one complete rotation to each two complete rotations of the crank,

Mounted in suitable relation with other parts of the loom is a take-up mechanism for taking'up the cloth as it is woven, a

characterizing feature of which is thaty the actuating means therefor is in operative re lation thereto for only a movement followlng a plc part of the lay and is there-- after released or. freed from all control of the actuzting means during the .remainder of the lay movement. As well understood by those skilled inthe art, the picking mechanism is actuated to throw the shuttle when back position, such as indicated by full line in Fig. 2; andthe present inventioncontemplates that immediately thereafter the takeup mechanism shall vbe actuated to take-up the cloth and then be released or' freed, so that durin that part of the'crank vshaft movement ollowing` the'release of the take- I up mechanism, the lay may be freely moved back and forth b'y the loom tender without corresponding actuation ofthe take-up mechanism, such action by the 100m tender being frequently desirable or necessary in piecing up. or in vbringing the warp threads into the same plane for other reasons, as well understood by those skilled in the art. In Fig. 2, the full line position of the crank is intended to represent arbitrarily the position itoccupies at or about the com-A pletien of the picking movement, .and the dotted line position as that reached by the crank when the take-up for that pick has been completed, the present invention having in view a release of the take-up mechanism or at about the dotted line lsition of the crank, so that not only may tiie take-up be actuated by hand after such dotted line position of the crank has been reached, but that the lay may then be moved forward and back by hand without causing take-up of the cloth, all of which will appear from the following description of one form of menns'to' the above ends.

Supported between-suitable brackets 18 secured to the loom frame is a cloth beam 19 on which the cloth 20, Figs. 1 and 2, is wound as itis Woven, said cloth beam being preferably of the character shown, described, and claimed in a prior application, Serial No. 650,208 filed Sept. 19, 1911, though. it is to be understood, that so far as features of the present invention are concerned, the cloth beam may be of any desire-d character or construction.

h'lounted in suitable bearings 21 supportedby the loom frame is a sand or takeup roll 22 about which the cloth passes, as indicated by dotted lines in Fig.` 2, a guide 65 roller 23 supported in suitable relation to the sand or take-up roll 22, Fig. 2, as by the brackets'24, being preferably employed to cause the cloth to engage a large portion of the sand roll and thus4 insure proper take-up action by the said roll whengit is turned clockwise, Fig. 2.

The shaft 25A of the sand lroll has secured to one end. thereof a, sprocket wheel .26 aboutA which passes the sprocket chain 27 for driving the cloth beam 19 through the lfriction drive device 2S, and said friction device may be of any'deslred construction to permit the cloth beam to rotate at gradually decreased speedV as the cloth roll thereon increases in diameter, and as shown, is pref- 80 erably, though not of necessity, the same as disclosed in said prior application to which reference may be had.

At its o posite end portion the shaft 25 of the sand) or take-up roll is provided with ,a worm wheel 29 which engages and is driven by the worm 30 suitably supported in the bracket .31 sustained by 'the loom frame, the construction tbeing such that Aspeed of rotation of .the -pinion 32 and perforce that of the sand or take-up roll 22 may be varied by substitution of change pinions 33 of different diameters.

As hereinbefore noted the present invention contemplates operative engagementbetween the take-up mechanism and its actuating means to properly take-up the cloth following each pick and then release of the take-up mechanism from its actuating means, so that in case the parts of the loom l be moved by hand, as for instance, if the lay be moved forward and back, no take-up of the cloth will be effected, the take-u being free at such time and capable of in( ependent hand manipulation. As one form ofmeans to this end, the actuating shaft 35 is mounted in an inclined direct-ion from front' to rear of the loom in suitable bearings 36,4 37 carried respectively by the brackets 3S, 39 and is prevented from endwise movement therein by suitable collars, as 40, 4l, one at each side of the bearing 36, Fig. 2. Mounted en the inclined actuating"shaft is a beveled pinion 42 meshing with a beveled pinion 43 of twice the number of teeth mounted ou the cam shaft 14, Fig. 2, the construction being such that u on one rotation of the cam shaft the inclined actuating shaft will 130- end 49 of said pin will be projected beyond 'the end of said shaft into the position indipin due to rotation of' the actuating-shaft,

' pinion 33, )in wheel 50 and sleeve-or bush- -bent up end v156 engaged with a recess 47,

-sleeve to the left, the end 49 of said in will :take-u mechanism, the-planes of rotation'- of sai pin and pin Wheel being at an angle 'der,53 against which one -end of the hub 5M the end 49 of the',actuating pin 44'.

- amamos make two revolutions, and since the cam shaft makes one rotation to two rotations of the crank shaft, it follows that the inclined actuating shaft 35 rotates in unison with the crank shaft.

The inclinedactuating shaft 35 carries an' actuating in 444 atits end adjacent the.- trainiof ta e-up mechanism, said pin being conveniently disposed in a longitudinal recess 45 formed in said shaft and having a Fig. 5, ina sleeve 48 rotatable with but longitudinall movable on said shaft, the construction ing such, that upon movement of the sleeve to the richt, Fig. 5, or toward the end of the inclined actuating shaft, the

cated in Fig. 5, and upon movement of said be retracted, all for a purpose as Wi l herel inaft'er appear. Arranged in co-acting ne-" lation with said actuating pin 44 is-a pinx wheel operatively related to the train ofj toeach other, with the result, that, during a portion of the rotative movement of the said pin will engage with and actuate the. pin wheel and then owin to the relation of I the planes ofrotation o said pin and .pin wheel, they will .pass out of operative 'en 'gagement and the pin wheel with its con. nected'train of take-up'l mechanism will be free.- As a good-practical embodiment oi@ this feature ofthe invention the pin wheel, 50 is formed on one face of or secured tothe; pinion 33, Fig. 4, carried'by the stud shaft, 34, said.pin wheel and pinion having their; hub portions -51 supported directly byf'the@ sleeve or bushing 52, Fig. 4 having a shoulmay bear. The sleeve or bushing 52 'ex`-f tends beyond the face 54 of the pinion 33 and; is mounted on the stud shaft 34,the latten passing through the slot 55' of the curved bracket 56 secured to the loom frame and 59 are provided for the outer end-of the stud shaft, the construction being such that. by loosening the nut 58, the -stud shaft,

ing 52, may be adjusted in thecurved vslot 55 of the bracket 56 to suit the`size of pinion 33 employed for actuation of the pinion 32 and sand or take-up roll; and by ti htening said nut the parts may be secure lin. desired adjusted position with 'the teeth nf the pin wheel in position to be engaged by Details of the 'described embodiment 'of the invention may be obviously ehapged without departin from the characterizing filling is 4to be changed'.

features thereof, ut\the for-1n of .parts described has .been found mechanillywell adapted to the purpose of the invent-ion.' It will be noted that in the'forntand 'relation of actuating pin and pin -wheeQ-tlie' latter is disposed torotate in a4 plane parallel to the plane of the connected pinion 33, while the p la'ne of rot-ation of :the pin-is inclined lthereto, thou h obviously the dSired 'relation might be ot erwise secured; whoreby, as the pin rotates under thedemand of 'the actuating shaft, it willengage the pin wheel and turn4 it for a portion of its ath of rotation and then the pin will ass rom engagement with the pin Wheel, eavin it and perforce the -take-up mechanism "ree and :subject to hand manipulation. Since also, the inclined actuating shaft is caused to rotate .in unison with the crank shaft, the actuating pin 44 is so disposed that whenthe crank shaft reaches the full line position,

Fig. 2, the picking action havin at or about at that time been completed, sai pin -will be engaged with and will actuatc the pin wheel tocause take-upof the cloth, until, when theV crank 5 reaches about the position shownby dotted, lines, Fig; 2, the p1n will pass from engagement with the, pin wheel and leave it and the connected take-up mechanism free. Thus should the loom be -sto pedat any time, theattendant may lay back and forth by hand throughout its ull `cycle of operation Without causing ace tuation of the take-up mechanism, except at, that portion of the cycle indicated between the full and dotted line osition of the crank 3100 in Fig. 2, such 'capacity eing inherent in the take-up actuating means without additional parts. Likewise the attendant may at suchl times freely manipulate the take-up by hand without disengagmgor adjusting any of the parts.'

-In order to restrain yaccidental movement of the take-upeither to let back or wind up Athe 'cloth during the-time'the take-up is disconnected fromjits 'actuating means, lthe 11o.4

sleeve'qrvbushing 52 is provided with an arm 60, Fig.` 4, havinga spring restraining 1ingerll f or engagin the pin. wheel, or'other part connected to t 1e take-up mechanism. When .illingfailssome looms are stopped, while others automatically supply fresh filling without sto ping. In either event it is desirable that t Vstake-up be arrested until take-up of the cl(.h,. istdictated by filling being properly lai l.the shed. In the present em iodiment of the invention, a loom 'is illustyatedlhaving llin replenishing mechanism which may be o any usual or desired character, and means are rovided to arrest the ytake-up when the kMounted in suitable brackets 62 secured to the breast beam of, the loom, Fig. 1, is the transverse shaft 63 having anla'rm (i4 foractuatng or movingadog 65 into-thelist) path of a suitable bunter carried by the'lay 6, When the transferrer 66 of any usual type well' known in the art, is to transfer a filling carrier GTfrom the hopper 68 to the shuttle in the box beneath. The transferrer and associatcd means for transferring. a' filling carrier from the hopper to the shuttle are or may be of well known type, and need not Ibe specifically described herein.

Connected to the transverse shaft 63 is an arm 69 adapted to be-moved to turn the shaft 63 clockwise, Fig. 2, lwhen the indicating means-70, of any desired orwell known construction, indicates absence of lling'on a detecting pick, and said parts being of Well understood construction and operation to those skilledin' the art, need not be specitically described, the general 'construction being such that shouldthe shuttle fail to lay llingon any detecting pick, the indicating mechanism 70 will be actuated by the weft hammer 71 to move the arm 69 to the right, Fig. 2, turn the shaft 63, andposition the' dog 65 of the transferring mechanism, so that upon the next beat up movement of the lay, change of filling will occur.v

Secured to-and extending downward from the transverse shaft 63 is an arm 72, Eig. 2, the lower end of which engages betweenthe collars 73 and 74 formed on arse-cured to the sleeve 48, which for identification vmay be knownas the release sleeve. Between the collar 73 and the bearing 37, Fig. 2, is a springl 75 acting normally to move and hold the release sleeve 48 toward the outer end of`the inclined actuating shaft so that the pin 44 may have its end 49 engaged with the pin Wheel in the manner heretofore explained. p

From the construction described itwill be noted that when the transverse shaft 63 is rocked clockwise, Fig. 2, on the occurrence of a filling fault in the manner-stated and filling is to be changed, the arm 72 will also -be moved to force the release sleeve 48 to the left, Fig. 2, against the stress of the spring75 to thereby carry the end of the pin 44 out of operative position with respect to the pin wheel; and when upon replenishment of filling, the fillingA is properly laid in the shed, the spring 75 will move the release sleeve to the right -to bring the end 49 of the pin 44 into operative relation with the pin wheel. It Ilwill therefore be noted that when filling is to be changed the takeup is released from its actuating means but upon successful replenishment and filling being subsequently laid in the shed, the takeup mechanism and its actuating means are again restored to operative relation.
