' liable to be caught between the side of the shuttle and the inner surface of the front box plate upon call for re lenishment', thus leaving a length of s ent ing to be carried into sequent pick of the shuttle. It is desirable to line the front box plate with a friction material such as leather or the like,

but where this has been attempted heretofore,-

the filling between the shuttle eye and inner end of the shuttle box has clung to the friction material and emphasized the liability of weaving defective cloth.

An im rtant feature of the present invention consists of-a shuttle box of the replenish ing type having a front box plate of novel construction whereby the objectionable con ditions existing heretofore are overcome an the weaving of perfect cloth made possible.

the front box plateis provided with a longitudinally extending slot in line with the 1ongitudinal thread groove in the side of a boxed shuttle and open at its inner end, that on call for replenishment the old filling end may be withdrawn freely from the shuttle throughout its entire length.

Another novel feature of the invention consists of a front box plate having a slot extending longitudinally thereof and dividing the box plate into a lower anchoring member and a shorter upper member supported solely by the anchoring member at the outer portion thereof with the result that the first impact of incoming shuttle is resisted by the rigid anchoring member below the thread groove in the shuttle and thereafter by the shorter upper member as the shuttle enters more fully into the shuttle box.

I member is unsupported except at the outer ortion of the anchoring member,the checkmg action of the shorter u per member may be made resilient to some egree and both of said members may be faced with leather or other friction material by virtue of the fact the longitudinal slot in the front box plate coincides or is in line with the longitudinal thread groove in the boxed shuttle thus providing a space in the shuttle thread groove andopen slot of the box plate in which the thread will naturally rest with no tendency to drop between the contacti side of the shuttle and inner face of the anc oring member.

The invention and other novel features thereof in addition-to the above willbest be made clear from the following description and accompanying drawings of one good practical form thereof. In the drawings Fig. 1 is a plan view of a replenishing shuttle box containing the present invention,

parts of the lay being broken away;

Fig. 2 is a front view thereof; Fig. 3 is a perspective view of the front box plate detached;

Fig. 4 is an enlarged end view of the front d' box plate looking in the direction of the arrow of Fig. 3; and V Fig. 5 is an enlarged cross-section on the line 55 of Fig. 2.

The lay 1 maybe of the usual character and be provided at its outer end with a replenishing shuttle box 2, the latter having the usual bottom opening 3 for thepassage of the ejected fillin carrier or bobbin during re- In accordance with the present invention the front box plate shown to be detached in Fig. 3 has a longitudinally extending slot 4 which is in line with the usual shuttle groove 5 of a boxed shuttle. The slot 4. in the box plate is closed at its outer end as at 6 and extends longitudinally and substantially centrajlf dividing the box plateinto of the box plate towards the inner end 0 'the latter, thus an anchoring member 7 and upper member 8, the inner end'9 of which terminates short of the inner end of the shuttle box as more clearly indicated in Figs. 1 and 2.

provided with slots through which the

bolts

12 and 13 pass. l

The outer end portion of the slot 4 is enlarged at 14 to provide an entrance for the now well known cutter and clamp for parting the filling adjacent the shuttle eye and clamping it for outward movement by the parter and clamp as the latter moves front wardl It will not be necessary to herein descri e the parter and clamp as the details 4 of these features form no part of the present invention, which is more particularly directed to the front box plate and its novel constructiom In the construction of the shuttle box heretofore devised there has always been the danger of the-filling being clamped between the side of the shuttle and the inner surface.

of the front box plate and especially will this occur on the filling overthrow or balloon as the shuttle comes to restv lln the present construction of the front box plate, how: ever, the longitudinal slot which divides the front box plate into the anchoring member and upper member and wherein-the upper member is shorter than the anchoring member the liability of filling being caught between the shuttle and front box plate is entirely overcome, since the space afforded by the longitudinal slot in the box plate and the longitudinal thread groove in the side of the shuttle provides an unobstructed openin in which the filling may rest.

nasmuch. as the upper member 8 is supported solely by the anchoring member at its outer portion, the inner end of the upper member is free and provides a space between the end thereof and the end of the shuttle box in which any overthrow or ballooning of thread may escape without entering between the shuttle and box plate.

As hereinbefore noted the anchoring member of the box plate is longer than the upper member and said anchoring member extends substantially the full length of the shuttle box with the result that the rigid anchoring member will first take the impact of the incoming shuttle below the thread groove as it enters the shuttle box and thereafter the up-,-

per member will act upon the shuttle as it passes to picking position. v

It may be advisable in some cases to strengthen the connection between the outer end portion of the anchoring member and the upper member and this may be readily eilected by the metal reenforced member 15 as indicated in Fig. 3.

Heretofore it has not been feasible or practical to line the front box plate with a friclength of the aramie tion material owing to the liability of the filling being caught by the frictional material and thus emphasize the objections heretofore existing in the filling being trap ed between the shuttle and inner face of the box plate, but with the construction. of the front ox plate as hereinbefore described where the upper member is shorter than the anchoring member to provide an open ended slot, it is possible to line both the anchoring member and the upper member of the front box plate with the frictional material, such for instance as leather, and in the present instance of the invention the leather lining 16 has two legged portions extending full slot in the front box plate, one of said leg portions 17 being secured to the upper member-of the box plate, and the other leg portion 18 being secured to the inner face of the anchoring member. One; good practical means of securing the leg portions of the leather or friction material to the anchoring member and upper member, the outer end ortions of each leg as at 19 may be turned outwardly towards the front of the box plate and secured to the upper and lower members v by screws such as 20 In some cases the friction material may be adhesively secured to the anchoring member and upper member and additional screws such as 21 may be em ployed.

By the provision of the front box plate with the longitudinally extending slot as described, in line with the thread groove in the side of the shuttle, and the termination of the upper member of the front box plate short of the inner end of the shuttle box, the filling thread of the outgoing carrier or bobbin may be readily withdrawn frgntwardly through the slot of the box plate with minimum tension or breakage.

On replenishment of filling the spent filling end may be readily withdrawn frontwardly through the slot of the box plate through the open inner end of the slot and to prevent the old filling end from being carried into the shed or caught upon portions of the front box plate, the anchoring member is provided with an abutment 22 substantially at right angles to the longitudinal axis of the shuttle box, the abutment 22 thereby preventing the old filling end from entering the shuttle box or being drawn into the shed during the lay operation.

in replenishing looms where the filling carrier or bobbin is changed from time to time the end of the new filling is secured at some fixed point such a lug or projection on the hopper or magazine, and in order to prevent the end of the new filling from being carried into the shed the upper member 8 of the front I direct the thread into a holding notch 24 formed in the upper edge portion of the anchorin member. From the construction herein efore described it will bea parent-that the front box plate havin the ongitudinal anchoring member and t e shorter u per member separated by the slot in the box p ate, provides a'space between the end 25 of the anchorin member and the end 9 of the upper member in which the thread may overthrow or balloon when the shuttle comes to rest without danger of being caught or trapped between the shuttle and the inner face of the front box plate.

As hereinbefore suggested the upper member 8 of the front box late is solely supported at the outer end t ereof so that a certain amount of resiliency will be permitted the shorter member of the box plate as the shuttle passes to picking position.

It may be desirable at times to form the inner end portion of the anchoring member with an upwardly inclined edge as at 26 which serves to prevent the outgoin filling end from being caught by the securing bolts for the anchoring member.
