Application filed June 11, 1999. Serial No. 501,482.

IHopedzile, in the county of Vvorcester and trolling the. supply of'the filling carriers as understood that the invention is not circumscribed by, such details,

Stateof Massachusetts, have invented an Improvement in Filling- Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing'like parts. I I The invention to be hereinafter described relates to looms, and more particularly tothat "type. known as filling replenishing looms, wherein, at desired times, a new supply of filling is furnished the weaving. inst-r'umentali'ties. l

The aims and obj ects of the presentinvention are directed to ilriprovedmeans for conthey 'are directed to'the transferring position and to the means for controlling the filling'ends, all of which will best be-made clear from 'the following description of one form or'embodiment of means for carrying the invention into practical effect, it beingsetfdi th bythe claims;

In the drawings: Figure'lis a front- View of the filling carrier supplying means and .its associated parts, showing one form or embodiment of the present invention; Fig. '2 is a View looking into thetop of the hopper and showing the relation the bobbins 'assume With respect to each other; Fig. 3 is a vertical section on the line zvw, Fig 1, looking in'the direction of the arrow a, Fig. ,1; :Fig. 4 is alike vertical section on the line 00, Fig. 1, looking-in the direction of thearrow' 6, Fig. 1, the top part of the hopper being broken awa-y; Fig. 5 is a section on the line 55, Figs. 1 3 and 4; vFig. 6 is a sectional detail-of the bobbin tip supporting .fing'er. on line 6'"-6, Fig. 1; Fig. 7 is a sideview of the hopper and its associated parts, looking from the'ri'ght of-Fig.1 1 Fig. 8 is a I "-view; of the filling end controller, loo-kingin the direction o'f-the arrow-c, Fig. 7; Fig. 9 is .a sectionsl detail' on the line 9-9, Fig. 7;- and F igs. 10 and :ll'are detached detail views .in side and edge elevation showing the filling end guideand support for the filling lea-din ferredr, 16cm frame l-havin'g-any .usualorrespect to these features.

except as herein-after the web or flange '14:, Figs. 1, and 5,hav-

giirom the car-riernext to be trans desired form of breast beam, the lay 2 havmg the shuttle box 3 and-bunter'4 adapted to actuate any usual or desired character of transferrer 5 through themediumofthe ,transferrer dog 6, shown as pivoted at 7 to the .arm 8 of thetransferrer, the spring normally acting to maintain the transferrer in raised position, and other associated parts acting to effect a' replenishment of filling at desired times may be of any usual or pre- "ferred construction, it being understoo d that the present invention is not restricted in any 1n the resent embodiment of the invention the s uttle box 3 is shown as provided with the usual open bottom 10, through which the filling carrier leaving the shuttle 11, Fig. 3, may pass'as the fresh filling car rieris moved into the shuttle by the trans ferret. I g

Mountedconvenient-ly on the breast beam or loom frame is a bracket 12, Fig. 1, shown as secured inpla-ce by suitable bolt connection 13, and furnishing a supportpr, sustainingelementfor the filling carrier supplying means or hopper, which, as an entirety,,may be identified by A in Figs 1, 2, 3,4,5a-nd7. e

Rising from'the bracket or support 12 is Patented May 3, 1910.

ing a bearing 15 for astud shaft orf'arm 16, I

which may be suitably secured thereto a sby the set screw. 17. The web'l' is extended rearWard,-as shown inFig'lj 3, andsupports one end wall 18 of the hop'per'iA. Secured to the stud shaft or arm 16 is, a web 19,-Figs.

1, 4, 5 and 7, similar, it may be, tothe web l l and furnishing a support for the-other end wall 20 of the hopper .A.. The two Walls 18 and 20 of thehoppermay be joined together at the rear by any suitable means toform a rigid structure and are preferablyso connected by a covering to-' protect'the filling carriers from oil or flyingdirt from the moving parts of the loom. In ithcpresent form of the invention the-joining element is a frame 21, Figs. 1, 2, 3, 4 and 5, extending across the top and bottom and along the rear of the side- walls 18 and 20 of the hopper, and furnishing asustammg frame or seat for a rear cover plate 22, Figs. 1, 3,

4 and 5, which may be oflight sheet metal.

The tram 21 maybe connected to the end wall 18 of t e hopper by suitable bolts 23 or the like, and the hopperlias a whole be braced,

if desired, by an arm 24, Fig. 1, secured to a fixed part of the'loom frame. The frame'21 has a flange 25, Figs. 2, 5 and 7, turned toward the end wall and which in connection with the end wall 20 forms a support and guide for the tip ends of the filling carriers, as indicated, t e flange and wall 20 forming between them a slot 26, Figs. 2, 4, 5 and 7, throu h which the filling ends extend, the walds of the slot being prevented from coming together and clamping the filling ends by appropriate means, such as.

the bulb or enlargement 27, Fig. 7, formed on 01 extending from one of them. The end walls 18 and 20 of the hop er have flanges 28 and 29 respectively, whicll, with said end walls and rear covering or plate, complete.

a suitable form of hopper and guide for the filling carriers 30 as they move toward the filling transferring position beneath the end 31 of the transferrer 5, Fig. 3. At its lower portion the hopper A is turned or curved so as to guide the filling carriers 30 to proper transferring position, Fig. 3, at which point the hopper adjacent the heads of the bobbins is provided with a throat or passageway 32, the rear wall 33 of whichis'suo stan'tially, fixed or stationary, and the front wall of which may be formed yielding in any suitable manner, as by a. spring 34 secured to an arm 35 projecting from the flange 14; of the hopper support. It will be noted that the spring 34 forms a stop for the filling carrier next to be transferred, and normally obstructs the throat or passa'geway 32 so that the bobbin next to be transferred will be sustained in transferring position until the transferreris actuated, at which time the stop 34: will yield and permit the filling carrier to pass through the throat or passageway into the shuttle beneath. As the transferrer thuspushes the carrier into the shuttle, its upwardly extending head portion 36 serves to prevent the remaining filling carriers from descendinguntil after the transferrer has again returned to normal position, at which time the column of filling carriers in the hopper will move downward until the carrier next to be transferred meets the yieldingstop At the tip end the'fillin-g carrier next to be transferred is sustained by a yielding finger 37, Figs. 4 and 6, having a stem 38 extending through-the web 19 on which is fixed a .collar 39, Fig'b, having one end of a spring 40 secured thereto, the other endof the spring being secured to the Weber other fixed part, the construction being such that asthe filling carrier is transferred to the shuttle, the finger 37 will yield downward and direct the tip of the filling carrier into the shuttle.

. As one form-of means for stopping the tip ends of the fillingcarriers, as they successively move to transferring position and maintain the column offillirigcarricrs from downward movement during theact of transferring, an arm ll having a stop head 44:, Fi 4 and 5, is loosely mounted on the stud siaft l6 and caused to move with the transferrer by appropriate or suitable means, as, for instance, a-lng 42, Fig. 4:, extended from the transferrer, on which rests a projection 43 extending from the stop head 44.

Regardless of details in the structural for mation of the hopper or filling carrier sup ply, it is desirable for the best results that the filling carriers be prevented from rotative movement on their axes during their travel to transferring position, and it is also of importance that the filling end leading from one carrier be not engaged with the tip end or other portion'of another filling carrier during such travel. In filling carrier hoppers constructed as heretofore, much I difficulty ,has been experienced from such rotative movement of the carriers and also from the filling ends becoming engaged with the tips of other'carriers or bobbins. l-Vitli these facts in mind the present invention aims to provide a filling carrier supplying means in the general form and character of a hopper wherein rovision is made for overcomin these de ective and objectionable 'COlldltlOIlS. In these respects the present form of the invention-embodies a hopper the .upper portion of which is made su ciently wide from front to rear to permit the filling carriers to assume a staggered relation with respect to each other, as indicated in Fig. 3,

and the lower portion of which is contracted from front to rear that the carriers, as they approach transferring position, may be ar ranged in single file. The effect of thus constructing the hopper is that in the portion where the hopper is relatively wide from front to rear t e filling carriers 30 will wedge agalnst each other and alternately against the front and rear walls of the hopper, so

that in their progression toward the transferring position at the bottom of the hopperthey will move'as abody without axial rotation of the individual elements or carriers composing it. By this construction also, as

"shown by' Fig. 2, and the alternate-disposiling carriers. at the front and tion of the fi rear of the hopper, the filling end 45 leading from a filling carrier above will not be directly over the tip portion 46'of the filling carrier next below it, as would be'the case if the filling carriers were in sin 1e vertical file, and consequently the tip 0 the lower filling carrier will not catch the loop of filling end leading. from the carrier next above it, a condit1on which would'eause a break in the filling of the upper carrier when the lower carrier was transferred or when the carriers assumed single file relation as they move toward transferring position.

These characteristics of the present inven-v actuator 56, serves to actuate the, shaft 54 as:

the filling carriers move to. pos1tion,--0f-trans;-: fer, or in other words to cause the-shaft ,54,

tion are of great practical importance, and this is the first instance, so far as known,

where a hopper for the supply of filling axia rotation thereof as they move to transferring position, and'where engagement of a filling end leading from an upper filling carrier by the tip of a filling carrier below it has been prevented. In theepresent embodiment of the invention as to these features the hopper .is made flaring from the lower to the upper portion, Figs. 3 and 'Z, so that the filling carriers may alternately wedge between the next adjacent carrier and front and back wall of the hopper, and the lower portion of the hopper A is gradually contracted in. width from front to rear to cause the carriers to automatically adjust themselves into single file for presentation singly to transferring position. This gradual contraction of the hopper may be formed by curvingthe rear protectin cover, and the front of the hopper at this point may be formed. of'the finger or flange portions 46 'detachably connected to the end wall flange portions 28 and 29 by the bolts 47, the flange portions 46 being formed with front wardly curved lower ends 48 connected by a brace 49 and directed toward the transferring position tocomplete the front wall of the guiding path for the filling carriers. As the filling: carriersmove downward .in the hopper toward transferring position, it is desirable that the slack that would be caused in the filling ends if the terminal parts were secured to a fixed support be taken up, and for this a filling end controller is provided which will act upon the filling ends in re-. sponse to th'e downward movement of the filling carriers in thehopper to take up all slack.

One formof filling end controller is. shown, but it will be understood that the invention is not' restricted thereto; Secured to .the end of the 'studshaf-t or rod 16 .by means such .as aset screw 51 is" ing in the web19 and-ghaving secured thereto an actuator 56.' The actuator 56 is provided with a series of-seats or recesses 57toreceive the ends of and be actuated by tha'fill'ing" carriers 30 as they movetoward transfer-e ring position, as indicated in, ,Fig. 4.- .The

and cons quently thee wheel 57 5-, turn response to downward movement of the filling carriers and take up slack in the fillin ends as will presently appear. A stop paw 58 pivoted at 59 serves to prevent backward movement of the actuator 56, and a too 60 on the pawl avoids excessive uplift of the awl end by engagement with the stop 61, i s. 4 and 5.- fiisposed below the wheel 55, which may be faced with a fabric or cover of suitable character, is an idle roll 62, Figs. 7 and 9, carried by an arm 63 projecting from the rod 64 which is movable in bearings (55 and 6 and is surrounded by a spring 67- acting against the collar 68 to normally lift the rod 64- and maintain the idle roll 62 in contact with the wheel 55. The arm 63 is or may be guided in suitable slots 69 formed in a 'portion of the plate 52.

The bracket or plate 52 projecting rea'rwardly therefrom to provide a guide recess '71, Fig.- 7,-for the filling ends has an arm 70 which after passing under sald guide extend into the nip between the wheel 55 and idle roll 62', the arm 70 being extended backward, upward, and over the side face of the wheel 55 to actas a guide 72 for thefilling wall of the slot 26, through which the fillin I ends are passed has a decided .rearwar. bulge or swell near its lower portion where the filling carriers pass into single file in approaching thetransferring-position,

and that the lower terminal portion of said bulge: has a recess orrguide 75, see dotted the carrier next to be transferred andthe point where the filling end is held, as, for t instance, the nip of the wheel and roll, so

- lines Fig; 7 and full lines Fig. 4,- the purpose whereof is to insure suflicient filling betweenthat at the moment of. transfer thexffillipg-x,

-will not be brokenf As the filling move toward transferring. positionfitlie ing ends leading from the upper carriers 'in rriers the hopper-will furnish, more 'slack=- to lue taken up by the filling endcontroller than the filling ends 'leading from the carr ers nearer the lower.portion'=of. the hopper, as

Will -be, obvious, and, b the simple expedient described as. one em 'odiment of this feat thattheffillingmnd'leading from the fil ing carrier, at theltime-being in positkin' to be ,next-t'; n-sferredj'passesjbackward soa'niewhat l to the recess or guide 75 and then to the nip between the wheel and roll 62, or in other words it'is given a circuitous path between the bobbin or carrier and the point where the filling end is held, so that while suflici'ent filling for the transfer is insured it may still be held taut between the carrier and filling end controller. As shown in Fig. 1, the filling ends leading from the filling carriers in the hopper to the end controller or talie-up pass in front of a guard plate or wing 76, whereby the suction or air disturbance due to moving parts of the loom will be prevented from disturbing or acting injuriously upon the filling ends.

As'best shown by the detail views, Figs. 10 and 11, the guide 75 has projecting below it and to the rear, a supporting toe 77 which serves to support the filling end between the carrier next to be transferred and the point where the end of the filling is held, and in order that the filling end may readily slide off the supporting toe as the carrier is trans ferred, its upper surface is preferably inclined and the inner side edges thereof are out awa or rounded, as at 78.

It will be noted that the slack in the filling ends will be taken up by and in response to the movement of the filling carriers 'as they 30- pass successively along the hopper to the transferring position, and that the relation of the filling carriers in the hopper is such that they Wedge together, preventing individual rotative movement and that the filling ends lead alternately from the front and rear of thevhopper so that interference of the carrier tips with the filling and consequent breakage of filling ends is entirely avoided.
