onisxn shown at the loft in Fig. l, and the filling feelers A mgplmition To all whom it may mnvm' ir:

Be it lLlluWl: thot l, logo r '1. this, 2. citizen of the United Photos, roshling itl'. Worcrst r, in the county ol Worcester and lltote ol'. ,s, have invented certain new and nsolul l1 vcnionts in l i elt lleplenishing Looms, 0i which the following is :1. specific tron.

My invention relates to welt replenishing loorhs, and to that class of looms which have lilling changing mochanisni, and shilting or drop shuttle boxes, and filling of filling in the active shuttle, and cause the filling change mechanism to operate to supply fresh filling; and my invention particularly relates to the class of looms shown described in U. 3. Letters Patent No. 665,8l5, of January S, 1901., in which the filling feelers of the filling detector mechanism move'up and down with the shifting or drop shuttle boxes, so that the lilling lcolers will always nioin tsln proper relation to the shuttle boxes, and feel for and detect the practical exhaustion of filling in the active shuttle.

The object ol my invention is to improve upon the filling detector mechanism in the class ol looms referred to, and. to do away with the employnient of electricity, or a nmgnotized leeler in connection with. the filling detector mechanism, and to provide it mechanloelers for each shuttle box are preferably made in pairs, of caliper form, and are adapted 'to enter open-- ings in the lront of the shuttle box and the shuttle, and engage the filling carrier or bobbin above mid below its central longitudinal axis.

My invention consists in certain novel lez turos of construction of my iinprovexnents, as will be herein-- 1 v I have shown in the drawings in detached portion oi a loom having a magazine of the woll known Northrop type, shown and described in U. S. Letters .iatont, No. 529,940, of November 27, 1894, with my improvements combined therewith 7 Referring to the lrowingsz-lfigore l is a plan view of the front part of. adotncbeel portion. ol oloo|n with my improvements applied thereto, showing the lilling changing mechanism at the right, and. my filling (lo toctor nroclninisin at the left; the shuttle box is shown in section, ond a. shuttle in it with tho filling on the bobbin substantially exhausted, and the ports of the filling flu-M 1101 mechanism in position to indicate for a. supply or lresh filling.- Fig. 2 shows the o iposite position ol sonic ol' the yarts of the tilting detector mochin engagement with a. lull bobbin.

has a hub 24 adjusolly secured by a screw 25 on a vertically moving rod :36. The rod 2t; has the saintvertical movement as the litter rod 7 and shuttle boxes (3 carried thereon. 'llu-re is a guide. not shown, for the lower end of the rod 20. The rod 2U has secured upon its upper end, in this instance by nuts 27 and 28, see Fig. 3, a stand 29, which has a vertical movement with the rod 2o, an 1 has its vertically extending portion 29 made with sideextensions to extend into and travel in guides or ways in a plate 30, secured to the extensions 21 on the b'racktt 21, see Fig. 1. The stand 29 carries two vertically extending pins .or studs 3i and 32. on which ale loosely mounted the hubs of levers 33 and 34 which hubs are supported on the adjustable collars 31 and 32 on the pins 31 and 32. see Fig. -l. The leversi33 and 34 arc-connected by a link 35. to cause said lovers to have a parallel motion. The link 35 has two upwardly extending pins 35 last thereon, which have in this'instanee by a screw 37, a second feeler blade 38. The two blades 38 and 38 are substantially parallel to. each' other, and extend one above the other,

, with their inner ends adapted to enter, as the lay beats up, an opening or openings in the shuttle binder 39, and openings in the front side of the shuttle, to engage the filling on the bobbin, in case of a iull b0bbin,see Fig. 2, or to receive the bobbin between them in case of a substantial exhausted bobbin, see Fig. l, and thus act as filling detectors. One of tho levers, preferably the inner lever 33, has an arm 3: extending out from the hub of said lever, and when the filling feelers 38 are in their inward position, with the filling on the bobbin in the shuttle substantially exhausted, as shown in Figs. 1 and 4', the free end of the arm 33 is in engagement with the inner edge of a bar -10, to hold said bar against a pin 41, which extends into a recess 40 in the rear edge of said bar 40. The outer free end of the bar 40 is supported on and guided by the extension 21 on the bracket ill, and the inner end of said bar is pivot-ally ,oi the angle lever 20, the hub 20 of which is pivotally mounted on a stud 20 see Fig. 1, the other arm of the angle lever 20 is connected with the vertically mo"\'-- ing plate 19, as'above described. A lei spring 46 is attached at one end to the stand 21" f bearsat its other lree end against the inner edge or the bar 46, and acts to move said bar outwardly. A pin 4]. wnieh is adapted to extend at its inner end into the recess 20 in the outer edge of the bar 10, isadji-istably secured by a screw 47 in a hub 4-7 on a sliding bar 48, which is pivotally connected at its inner end by a stud 50 to a projection 5.1 on a collar 51, secured by two niits 52 on one end of a longitudiiutl sliding rod 53. The rod.53 is supported and has its bearing in a hub on the end of the stand 21. 'lhe other end of the rod 53 is pivotally connected with one arm or" an angle lever 54, the hub of which is pivotally mounted on a pin 55, seeFigs. 3 and 5. The other arm of the angle lever 54 is connected through a link 56 with a lever 57,9which has a rocking up and down movement communicated thereto at regular intervals, from a earn, not shown, on a driven part of the loom; The outer end oi the sliding bar 48 extends through an opening. in the support 21, secured to the bracket 21, see Fig. 4. and is bent at an angle to the main portion, and has a hub 48 at its extreme end, in which is secured, by a screw 58, a, pin 59. There are a set of levers 33 and 34. and a link 35, a wire 36, bloc-K36, and l'eeler blades 38, and 38 for each shuttle box of the drop shuttle boxes, in this inslai (to two drop shuttle boxes are shown, and two sets of lovers 33 and 34, and parts connected therewith. in case of additional shuttle boxes, there will be additional sets of levers 33 and 34 and partsconnected therewith.

The opemtionot' niy iniproven'ients above described,

will be readily understood by those skilled in the art from the above description in connection, with the drawings.

When the lilling on the bobbin in the running shuttle in the top box is substantially exhausted, as shown in Figs. 1. and 4. the parts of my filling detector mechanisiu. when the lay isat its forward stroke, will be in the position shown in Figs. 1, and 4, the arm 33 being in engagement. with the inner edge of the sliding rod 41), and holding the notch 40, in the outer edge of said 41. The longitudinal movement of the. sliding rodB, in the manner above described, in an outward direction, will carry the sliding rod 40 with it, and through the rod 45 will move the angle lever 20 to raise the plate ll), against the action of the spring 19", and allow the spring l7.to move the lever 16, and disengage the hook arm 15, to allow the dagger 13, operated by the spring 14, to move into the path of. the hunter on the lay, and through the engagement of the hunter with the dagger, operate the translerrer 11 to supply fresh filling, in the usual and well known way.

The operation of the filling detector mechanism is so timed, that alter the filling feelers or blades 38 and 38 have indicated for a'supplyof fresh filling, the shuttle, having the substantially exhausted bobbin therein, is thrown to the other side of the loom to receive a fresh bobbin. When the bobbin in the runningshuttle is full ol filling, and until it becomes substantially exhausted, the engagementoi the endsot the filling detectors or blades 38 and 38 with the filling on the bobbin, as shown in Fig. 2, and in the lower boy. in Fig. 4, as the lay heats up, moves backwardly said blades, and with thorn the link 36 and'the levers 33 and 34, into the position shown in Fig. 2, disengaging the arm 33 from the rear edge 01' th'esliding'oar 40, leaving saidbar fiee'to move on its pivt'ital support, and thus allow tbe'i'nriey end of the pin 41 to move out of the notch 20 in said bar 40, in the movgt-nient oi the sliding bar 48, without moving said bar 40 and operating the filling changing mechahism. On the return movement of the sliding sliding rod, in engagement with the inner end of the pin its 'bar'48, the pin 59 will engage the arm 33 on the lever 33, and move said lever, to cause the free-end thereof to engage the inner edge or the sliding bar 4(1 at 'r 'the pin 41 passes into the notch :40, as shown in Fig 1, and this opera tion is repeated at regular intervals as the loom operates.

Referring now to the modified construction shown in Figs. 6 to 9, inclusive. In said figures'is shown gne filling detector mechanism for one shuttle born The same figures of reference are used on the parts correspond ing to similarpartsin the other figures. The sliding bar 48 in Fig. '6 is not provided with the extended end carrying the pin' 59, shown in Figc 1, as the lever 33 is spring actuated, to cause the ifeeler. blades 38 and 38* to feel into the shuttle box. In this instance a lightcoil leaf spring 60,.oi a watch-spring type, is attached at one end to the projecting arm 33, and at its other end to the a on the other end of the link 35. The feeler blade Bil/has secured thereto, by a screw 62, a block 63, the upper\end nd of which is preferably slightly curved or rounded has secured thereto by two screws 64 and 64, the outerend of the upper feeler blade 38, see Fig. 8. By meansof the rounded surface on the iipper end of the block 63, the horizontal plane of the ieeler blade 38 may be adjusted, to cause the inner end of the febler blade to be nearer the end. of the fecler blade 38, by turning in the inner screw 64, and turning out the outer screw 64, as shown in Fig. 7, or the inner end of the focler bladc 38 may borne. ed farther awayfrom the color blade 38, as shown in Fig. 8, by turning in the outer screw 64, and by turning out the inner screw 64. By means of this adjustment of the feelor blades, the amount of filling to be left on the bobbin may be regulated.

In Fig. Slinstead of the two iecler blades 38 and 38, a single ieeler blade 38 is shown,-which is adapted to entor a single hole in the shuttle, and engage the bobbin at one point, preferably the central front portion, todetcct substantial exhaustion of filling thereon.

It will be understood that the loom will continud' to operate normally, until on the substantial exhausti u of filling on the bobbin'in thelriuining shuttle, tile iceler blades 38 and 38 indicate for a change of filling,

when the filling changing mechanism will operate in the, manner above described, to supply fresh lilling.

It will be understood that the details of construction of my improvements may be varied if desired, and they may be adapted to be applied to wci't replenishing looms oi: different kinds, in which one or more shuttle boxes, at the end of the loom opposite from the magazine, are used. l
