rnnnnn LOOM.

Application filed July 3, 1919. Sierial No. 308,385.

To all 10 720% it may concern:

Be it known that 1, Jonas Nonrrrnor, a citizen of the United States, residing at Hopedale. in the county of Worcester and State of Massachusetts. have invented certain new and useful Improvements in Feeler Looms; and I do hereby declare the following to he a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in feeler looms and more particularly to an improvement in bobbin chutes therefor.

Feeler looms are a type of weft replenishing looms wherein the weft replenishing mechanism operates to insert a fresh supply of fillingin the active shuttle when the old filling is exhausted to a predeterminedextent. as determined by the filling feeler mechanism. These looms are usually constructed with the weft replenishinginechanism located on one side of the loom and the filling feeler mechanism located on the other side of the loom. Upon the indication of critical or predetermined exhaustion of the filling by the filling; feeler mechanism, the weft replenishingoperation takes place upon the next succeedinobeataipof the lay. At this time the usual thread parter mechanism is thrown into operation to sever the filling end extending; fromthe selvage to the bobbin. hen the exhausted bobbin is eiccted from the shuttle it strikesa bobbin chute and is deflected into a receptacle; The bobbin chute usually consists of an apron mounted upon the lay or upon the frame of the loom and serves only the purpose of deflecting the exhausted bobbin.

The present invention .has for an object to provide a bobbin chute which is mounted in a novel manner. and which may be readilv applied to any loom and particularly those which are already constructed and in operation without changing the construction thereof. The invention has for another ohiect to provide a bobbin chute which, in addition to its functions as a bobbin chute, serves as a thread extracting device. which will engage the outgoing filling: end as the lay beats backward upon the first pick of the shuttle 'after replenishment, and hold the filling so that as the shuttle travels onward, its movement causes the filling to he pulled.

' therewith.

through the shuttle eye. To the accomplishment of these objects and such other objects as may appear, the invention consists in the structure hereinafter described andclaimed.

In the drawing which illustrates the preferred embodiment of the invention Fig. 1 is a sectional elevation of a portion of a feeler loom showing the improved bobbin chute and parts immediately associated Fig. 2 is a section on line 22 Fig. 1 viewed in the direction of the arrows. v The improved bobbin chute indicated generally by 10 consists of an apron 11, preferably of metal, and which is pivoted on the pintle 12, supported by a bracket 13 carried by a receptacle 14 and secured thereto by bolts 15, I

The receptacle 14 may be any receptacle employed to receive the exhausted bobbins when the replenishing operation occurs, and

is in the present instance shown as a metallic receptacle rectangular in cross section and having a cut away portion as shown in Fig. 1, which is designed to permit the receptacle to fit under the ordinary type of stationary bobbin chute. -The ltiracketlfi is of substantial construction and is preferably cast in such a form as to supply the cut away portion of thereceptacle It, so that in reality a receptacle is formed which has a substantiallv uniform height ofwall on all sides. The bracket 13 is provided with ears 16 adapted to fit over the rim portion 17 of the ordinary bobbin receptacle and is also provided with alugr 18 having: slots 19 -i'l1816]11 which are adapted to'fit over heads :20 of arms 21. The arms 21 are fastened to a portion 22 of the frame of the loom by the bracket 23 and bolt 2d. The receptacle 14 rests upon the floor as shown in Fig. 1 and its position under the loom is regulated by the length of the arms 21 so that the bobbin chute 1O inclines up under the shuttle box 25. In this position when the lay 26 is at the extreme forward point of its heat, and when replenishment occurs, the ex hausted bobbin falls from the shuttle box 25, strikes the apron 11 of the bobbin chute and is deflected into the receptacle '14.

The apron 11 is y'ieldingly held in the position shown in Fig. 1 by a coil spring 27 having one end 28 thereof bearing against the front surface of the apron 11 and the other end 29 against the bracket 13. It

sometimes happens that an exhausted bobbin is caught between the bobbin chute and the lay and should this occur the apron 11 is permitted to swing 'lforwardly. about the pintle 12, so that no dam: e can occur and no parts .be broken and v the bobbin has freed itself, the apron 11 is returned to its normal operating position by the spring 27.

It will be observed that the bobbin chute 10 can be directly mounted upon any receptacle without the use of the bracket 13 and in the drawing a receptacle of the ordinary construction for receiving exhausted bobbins is shown but obviously a receptacle of any desired shape could be used, the only requisite being that when the bobbin chute and receptacle are placed in an operative position, that the bobbin chute should extend up under the shuttle box'so that it will successfully'operate to-d'etlect a falling bobbin into the receptacle.

lVhen replenishment is indicated, the usual thread parter operates to sever the filling end extending to the selvage at a point. near the shuttle, and in the ordinary constructionot ieeler loom, the severed end is pulled through the shuttle eye by the ejected bobbin as it falls into the receptacle. Occasionally, and in fact frequently, it happens that this filling end is caught between the shuttle and the binder or the front wall of the shuttle box, and is held thereby, so that, as the ejected bobbin falls it doesnot pull the filling end through the shuttle eye. \Vhen the shuttle starts on its flight on the first pick a'l'ter replenishment it often draws the filling end toward and sometimes into the shed where, if it is allowed to remain, there results a double pick and consequent blemish in the cloth.

aware were mounted on either the lay or upon a part of the loom frame. These devices operate with more or less uncertainty depending on the chance of the filling end coming into engagement therewith.

in order to eliminate the uncertainty of operation of the thread extracting device, I have provided the bobbin chute 10 with a series of teeth or engaging devices 30. It will be observed that when the lay starts to beat back, and before the shuttle is started on its first pick of the replenishment, that the filling end extending from the ejected bobbin up through the eye of the shuttle is drawn directly across the mouths of the engaging devices 30, so that when the shuttle starts on its flight the filling end is engaged thereby so that further movement of the shuttle arts to pull the filling end through the delivery eye and prevents the formation of double picks.

I believe that I am the first to provide a bobbin chute which does not move with the,

lay, with thread extracting means, so that as the lay moves backward the filling is drawn into engagement with the thread extracting means. It is also to be observed that the receptacle and bo'bbinchute mounted thereon form a unit which may be applied to any loom but which is particularly adapted to be applied to looms which are already constructed, in which case the only adjustment needed is to regulate the length of the arm 21 so that the boboin chute extends up into an operative position under the shuttle box.

I claim:

A loom having, in combination, a bobbin receptacle provided with a cutaway portion, a bracket fitting into the cutaway portion and serving as a continuation of the receptacle to form with the receptacle a substantially rectangular body, a bobbin chute yieldingly mounted upon the bracket, and arms engaging with the bracket and adapted to be adjustably connected with the frame of the loom to maintain the bobbin chute in a definite operative position with relation to the loom.
