-- in llopedale, county of \Vorcester, and State of Massachusetts, have invented an Improvement in Filling-End Removers for Looms. of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to filling replenishing looms, and more particularly to means for removing from the 100m the end of the filling that projects from the cloth selvage after a replenishing operation, that it may not be carried into the shed. As a result of the re plenishing operation in looms of the filling replenishin, type. an end of filling is left PIOJQCtlDg from the cloth selvage, which is liable to find its way into the shed during weaving, with the result that defects in the cloth occur. Attempts have heretofore been made with more or less success, to prevent the occurrence of such defects in the cloth by providing means to engage and hold the filling end, sever it at the cloth 'selvage, and then drop the free piece of filling or withdraw it from the zone of operation of the loom parts. Such devices have caused the introduction of more less complicated and delicate mechanism into the'loonr structure which is mrticularly noticeablein eliminating the spent filling end from what are technically known in the art-as feelerloorns. \Vith these general facts in view, the present invention aims to'simplify and produce more ellicientand reliable means for removing the filling endfroin looms fol-lowinga replenishing operation; and,'while it is herein shown and described as associated with a loom of the, ffeeler type, it is to be under stood that the invention may be used in connection withother types of looms and that in its true scope, the invention is not re stricted to the details or particulars as illus trated and described, but may be varied within the definition of the invention as pointed out by the claims.

In the drawings: Figure 1 shows in plan view sufiicient parts of one'end of a loom provided with a good practical form of the invention to make. clearits construction and operation; Fig. 2 is a cross-section substantiall on the line 3-2 of Fig. 1, showing one form of means that ma be conveniently employed to part the filling adjacent the shuttle containing the filling carrier about to be abandoned, the said means being shown in its normal or inoperative position; Fig. 3 is a front end view at the lower portion of a loom equipped with a suctionpump which may be associated with other features of the invention; Fig. 4: is a section on the line l-4, Fig. 1; and Fig. 5 is a detail showing a screen for intercepting the filling ends in the filling end receiver.

In prior attempts to remove the filling end from a filling replenishing loom of the type wherein replenishment is effected prior to complete exhaustion of the filling inv the shuttle, a thread parting mechanism has served to part the filling adjacent the shuttle and another parting mechanism, such as a temple thread parter, has parted the filling end adjacent the cloth 'selvage. f- Insome cases the severed filling end has been held by the first-named thread parting mechanism to position the'filling for the "action of the temple thread parter and until the call for 'another' operation of the re plenishing mechanism, and then would release the filling end'as the parting mechanisin was made operative. The pres.-

ent invention, when associated "in a loom of the above type, contemplates that thefilling leading from tlie snbstantially exhausted shuttle shall be parted andthen released, and that the filling end shall pass at once into thecon'trol of a part of the present .invention, so that when freed from the cloth se1vage,"it may be removed from the loom- As a practicalneansto this end, the inven tion aims to p'rovide' a device preferably disposed between the cloth' selvage' and the shuttle box'fon the same sideiof theloom,

which shall act pneumatically upon thefilliiig'end, preferably by suction, so thatas soon as the filling of the practically ex; hausted shuttle has been parted near or ad j acentcto the shuttle, the free end thereof will pass at' once into the control of thesaid device which will hold the filling end in position for the action ie i tem'pie thread cutter and as soonas-"suc 1 aread'cirtter has acted, willcarry the now free piece of fillin'g away from all danger of being passed into the shedf f Any character of parting mechanism may be employed to part thefilling near or adjacent to the practically-exhausted shuttle,

vice referred to.

In the present illustrated form of parting mechanism for parting the filling adjacent the practically-exhausted shuttle, that illustrated and described in the Rhoades Patent, No. 922,511, dated May 25, 1909, is employed, but it is to be understood, of course, that this is merely typical of a means for parting the filling near to or adjacent the practically exhausted shuttle; and the temple thread cutter is herein typified as of the same general characteras that in, the Rhoades patent, although any character of thread parter that will serve to part the filling adjacent the cloth selvage may be suitable. I i I The lay .1 having the usual character of shuttle box 2 at the replenishing side of the loom; the breast beam 3; the transverse rock shaft .{t for controlling the transferring mechanism not herein illustrated; thefixed bladeo; the movable blade 6 pivoted at 7 on the arm Sand having the heel 9; the pivotal support 10; the yoke 11 having the bearings 12 and 13 and the pin 14; the jaws- 15 and 16 and associated spring 17; may all be appropriately formed, arranged, and constructed, as in the Rhoades patent hereinbefore mentioned; and since suchdevices and their cooperative relations are clearly set forth and described in the Rhoades patent, further elucidation herein is unnecessary. I M

When the filling end leading from the practically exhausted shuttle has been severed, and the severed end clamped by the fixed and movable jaws of the thread parter, it is desirable-that this severed end portion of the filling be freed from the clamping action of the jaws, and to this end the heel 9 of the movable jaw is provided with an abutment 18 preferably formed as a roller,

as indicated in Fig. 2, which is adapted tov contact with a stop 19 secured in appropriate position upon the breastbeam 3, as by the bolt- 20, the construction being such that after the thread parter has been moved rearwardly andsevered the filling-adjacent the practically exhausted shuttle, and the jaws have been closed and hold the filling end as set-forth in the Rhoades patent,

on the return or frontward movement of the arm 8 the abutment or roller 18 will strike the stop 19' and thereby open the jaws to free the end of the filling for a piuipose that will, presently appear.

In order that this opening or releasing movement of the partrents ing mechanism may be appropriately timed, the stop 19 has its shank portion 21 provided with a slot 22, Fig. 1, through which the bolt 20 passes, the construction being such that upon loosening the'bolt 20, the stop 19 may be adjusted to cause releasing movement of the jaws 5 and .6 at the desired time. I

The temple, which as a whole is designated 23, Fig. 1, is hereinQshown as provided with a suitable thread parter 24 adjacent the cloth selvage, but as such temple thread parter is well known to those skilled in the art and may for the purposes of the present invention be of any desired type, the particulars of its structure are not herein elucidated. I i

Secured in appropriate position, preferably upon the breast beam, is a bracket 25, Figs. 1 and 4, provided with a sleeve or tubular bearing 26, through which projects the tube or conduit 27, said tube or conduit 27 being normally held in position with its end 28 projecting toward the'lay 1 by suitable means such as a spring 29, preferably withinthe tubular bearing 26, one end of said spring bearing upon a collar 30 secured to the tube or conduit 27 and the other end finding a seat against the endabutment 31 of said tubular bearing, substantially as indicated in Fig. 1,--the construction being such that should the shuttle be trapped in front of the tube or conduit 27 or fail to enter "the box, the end of the tube or conduit 27 may engage the shuttle as the lay beats vupgand be moved frontwardly thereby,

air passing inwardly of the tllbGQI' conduit 27, so that when the end of the filling a, Fig. 1, has been parted adjacent'the practically exhausted shuttle, the free end of such filling may be drawn"v by the air suction into the tube or conduit 27 as indicated by the dotted lines in Fig. T; and that there after, when the filling end hasbeen parted at the selvage of the cloth, such, piece of fill-. ing may be at once removed from all danger of being carried into the shed. Various ex pedients will suggest themselves to those skilled in, the art, for producing the air curpassing inwardly of thetube or conduit 2 andit may be that where a series of looms are employed, the tubes or conduits I 27 of said series of looms may be connected to a single exhausting vmeans, such as a pump. In the illustrated form of the invention, however, the individual loom is in dicated as being provided with an air pump, but it is to be understood thatthis. is typical merely of a means for producing inward air currents through the tube or conduit 27', and that individual looms may each be provided with such or equivalent air pump, or a series of looms be connected to a single pump.-

Referring to Fig. 3 as illustrating an appropriate form of air exhaustion means: the crossbeam 32 of the loom has rising therefrom a bracket 33 to which is appropriately secured a supporting member 34, by suitable means such as the bolt 35, said supporting member 34 serving to sustain a cylinder 36. As a preferred means for sustaining the Y cylinder 36, the part 34 may be made as a part to surround the cylinder as indicated in Fig. 3, and be appropriately clamped thereupon by means of a bolt ,or other securing means 37.

Rising from the bracket 33 and preferably secured thereto by the bolts 38, is an arm 39 having secured thereto a bearing 40 for a shaft and band-wheel 41' carrying a crankpin 42 connected to an arm 43. The arm 43 at its upper position is provided with an appropriate connection such as a swivel pin 44 to a piston rod 45 which may. reciprocate in a suitable bearing in the upper portion 46 of the arm 39, the construction being such that as the pulley 41 is rotated the piston rod 45 will be appropriately reciprocated as will bereadily understood. As one means for imparting such movement to the pulley 41, the shaft 47, which may be either the crank or cam shaft of the loom, is provided with a large band wheel or pulley 48 operatively connected to the pulley 41 by an appropriate belting or band 49.

The piston rod 45 passes through a suitablepacking 50 at the top of the cylinder 36, and at its lower portion carriesan appropriate piston 51, Fig. 3. Connected to or formed upon one side of the cylinder 36 is a chamber 52 having a pipe connection 53 with the flexible tube 54. At the lower portion of the cylinder 36 and-communicating with the chamber 52, is an inlet valve 55, and preferably opposite thereto is an outlet valve'56, said valves being of usual type, and being duplicated at the top of the cylinder, although not therein shown by reason of being covered by the overlying parts, the construction being such that upon reciprocation of thepiston 51, air is drawn through the inlet valves 55 from the chamber ,52,

- thereby creating a suction or partial vacuum in the flexible tube 54 and inducing currents therein in the direction indicated in Fig. 3;

and-the air thus drawn into the cylinder is forced through the outlet valves 56', as will be readily understood. The air chamber may be variously formed, but the particular construction herein described has been found a good, practical form thereof, and as hereinbefore described, each loom may be thus provided with an air pump operated in appropriate manner to produce inward currents ofair throughv the flexible tube 54,

or a single pump located in any'portion of the; building may be associated with a plurality of looms and be appropriately driven from any source of power. Indeed, the'con struction indicated in Fig. 3 may be regarded as typical of such single. pump adapted for connection with a series 0 looms.

-The tube or conduit 27 has at its inner portion'a filling end receiver herein shown as a box-like device 57, Fig. 4, provided with a removable cover 58 and a screen or wire gauze 59 which will permit the passage of air but prevent the passage of pieces of filling, or other material.

Connected to the filling end receiver 57 is the flexible tube 54, the said connection being preferably formed by means of a tubular projection 60 at the bottom of the filling end receiver 57, as indicated in Fig. '4, though obviously other appropriate forms of connection might be employed.

From the construction thus far described, it will be apparent that when the filling in a running shuttle has become practically exhausted, and a change of filling is indicated,

the filling leading from the practically exhausted shuttle will be parted adjacent thereto, and the free end thereof will immediately be drawn into the tube or conduit 27 by the in'rushing currents of air, as indicated in dotted lines, Fig. 1. The filling end will thus be maintained under light drawing tension by the currents of air passing through the tube or conduit 27 which will serve to maintain the filling in position for the action by the temple thread cutter, and when the temple thread cutter has parted the filling at the selvage of the cloth, the now free piece of filling will be drawn by the currents of air through the tube or conduit 27 and into the filling end receiver 57, where it will be intercepted by the screen or gauze 59. Obviously, the filling ends may be readily removedfrom the filling end receiver at any time by merely lifting the cover 58 and taking them out by hand, or otherwise. It may at times be desirable to raise the screen 59 in the filling end receiver in order 'to clean the same; and to this end the screen59, which may preferably be formed of wire gauze or wire cloth, is appropriately secured to the two arms 61, which may project through the bottom of the filling end receiver as iridi- -cated in Fig. 4. As an appropriate means upper portion are provided-with sleeves or enlargements 62, the lower ends of which may rest upon the walls of theop'enings in the filling end receiver through which the arms 61 project. From the construction de-,

scribed, it willbe apparent that by lifting upon the end of the arms 61. the strainer or wire gauze maybe raised in the filling 'end receiver, the filling ends removed, and then becomes free it will at once pass along with the currents of air into the conduit and be held in this position until the filling is parted at another point, whereupon the piece of filling will becarried bodily by the air cur rents away from the weaving instrumentalities.

tion is the filling end receiver which serves to gather or receive the pieces of filhng'as they are carried away fromthe weaving 1nstrumentalities by the air currents passinginto the conduit so that all danger of pieces of filling passing into the shed is avoided.

' Where the conduit and air currents are employed to remove pieces of filling parted from the shuttle in which the filling has become practically exhausted, the conduit is supported with its entrance between the cloth selvage and shuttle box, and in such position that when the lay is in forward.

position, the filling extending from the cloth selvage to the adjacent shuttle box will cross the entrance of the conduit so that the currents of air passing into the conduit-will pass transversely ofthe filling.
