LOOIVIQ SPECIFICATION forming part of Letters Patent No. 637,753, dated November 21, 1899. Application filed July 19, 1899. Serial No. 724,385. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM H. BAKER, residing at Central Falls, Providence county, Rhode Island, and FREDERLC E. KIP, resid- 5 ing at Montclair, Essex county, New Jersey, citizens of the United States, have invented certain new and useful Improvements in Looms, of which the following is a specification.

to This invention relates to the class of looms provided with mechanism for supplying to the loom, automatically, filled weft-carriers, and which are provided with monitors or detectors which act when the weft in. the runr5 ning-shuttle is nearly or wholly exhausted to set in motion the weft-supplying mechanism.

In the construction which forms the object of this invention there is astationary magazine of some kind for the filled shuttles, a

2n shiftable and displaceable shuttle-boxon the lay or batten adapted to be moved from the picking-point to make room for a placer containing a full shuttle, means whereby the said placer or placing-pocket is made to re- 2 5 ceive a. full shuttle from the magazine, mechanism for effecting the shifting of the shuttlebox and "placer, and magneto-electric means for detecting the exhaustion of the shuttle-in play and for setting in motion said shifting .go-tmechanism.

One of the features of the invention is the manner of shifting the shuttle-holders when a full shuttle is to be supplied and the exhausted shuttle discharged, and another is the op- 3 5 eration of the shifting mechanism from a cam in the 100m, which rotates once for each two picks of the loom.

In the accompanying drawings, Figure 1 is l a side elevation of a part of the loom, illusotrating the application of our invent-ion thereto. This viewshows' the lay or batten in its advanced position, having beaten up, and the shuttle-box and placer in their normal positions. Fig; 2 is a similar-view to Fig.

5 1, butshowin g the lay receding and the placer in operation to supply a full shuttle. 3 is a front sectional elevation, the plane of the section being indicated by line w? in Fig. 1 and Fjg'i is'a frout"elevation of the-mags, 5o zine and placer, which are omitted frOL'HQEig.

3. Fig. 5 is a sectional View showing theplaber in plan, but empty. Fig. 6 is a side elevation ofthe fixed side of the shuttle-box, showing the electric terminals and circuits. 7 Fig. 7 is a longitudinal sectional view of the shuttle and bobbin with their electrical devices. Fig. 8 illustrates another construction of the magaziue. Fig. 9 includes aside elevation and a plan view'of the magnet, armature-lever, and adjacent parts on a larger scale than the :principal views.

thus puts the armature-lever of this magnet.-

into the path of an operating lever or arm to which motion is imparted by a cam on the loom, so that this cam, through said lever and suitable intermediate mechanism, shifts the said-displaceable shuttle-box, discharges the exhausted shuttle therefrom, puts the placer in position, and holdsitin line with the picker until the full shuttle therein is picked to the opposite side of the loom.

The arm then passes and the parts resume their usual or normal position until the shuttle in play is practically exhausted of weft, when the sup plying operation is repeated.

1 re resents generally the frame of the loom, 2 the reast-beam thereof, and 3the lay or lay-head, carried bythe lay-swords 3 which latter are fixed below to the swing-rail 4. The lay is vibrated in the usual manner from a crank 5 and connecting-rod 5*. parts are common, in some form, on looms now in use, as is also the picker-stick'G. p

The features which embody the present invent-ion will now be described.

All of these 7 On the loom frame is mounted ashuttleroe .posed therein. At the delivery-ontletot the spring 9 of any suitable kind holds the placera; a I I 037,753

lasort or trough mounted on an upright arm 8", whichturns at its'lower end on the swingrail 4 or on some adjacent pivotal axis. A

in its normal receiving position. 011 the lay 3 is mounted the shuttle-box 10. This box consists of a stationary part and a movable part. :The side 10 farthest from the magazine is fixed on the loom. The bottom. 10 and the side next the magazine, including the swell 10, forma movable part, which is'se,-=

cured to a pair of stems 11, that are guided in suitable keepers 12 on, the lay-head. -(Jonnected to the stems 11' is an upright guide rod and lowered to the proper extent. -Z. The operating mechanism of the placer and shuttle-box will now be d'escri'bed. I On the frame of the loom 'a lever 14 is fulcrqm'ed at m, and one arm of this lever is or slide 13, by which the box 10 may beraised coupled by a rod 15 to one arm .of an-elbow-f lever 16, 'fulcrumed atits elbow on 'the up-' .right slide 13, [The other arm of 'the'elbowlever is provided with a hook 16*, which is adapted under certain conditions, to be'here inafter explained, to engage a stud 8" on the arm carrying the placer 8. On the other arm of the lever 14 is fixed an electromagnet M, the armature a of which is fixed on one arm of an'el'bow-lever 17, which is provided on its other arm with a book 17. An ordinary armature-spring 17" holds the armature retracted normally, and a spring 14 holds the lever 14 in the normal position seen in Fig; 1.

The crank-wheel 5 gears with a wheel 18 of twice its own diameter, and on the shaft 18' of said wheeliis a cam 19, which will of course rotate oncewhile the lay is making two vibratory movements. .This cam 19 bears on an arm or lever 20, which may be held -up to the cam by a spring 21.

or lever isvibrated constantly whilethe loom;

This operating arm is inoperation, and it bears at its free end a hook 20, which plays close to the hook on" the armature-lever 17, and when the magnet M- is excited and attracts its armature the lever- 17 is rocked and itsv hooked end 17- put into the path of the hook 20. Let us suppose that while the lay is atthe picking-point an exhausted shuttle enters the shuttle-box 1O from thefopposite side of the'looin and through electrical means; tobe hereinafterdescribed,

completes a circuit through the magnet M.

The lay will afterward beat up the shot and start to recede; but before it again reaches the picking pointthe cam 19 will depress the lever 20, which will engage thelever 14 and ,rock' it, thus acting through the rod '15 and elbow-lever 16 to elevate the shuttle-box .10 and, shift the placer 8 to the position seenin Fig. 2. The exhausted shuttle will be thrown from the open rear side of the shuttle-box and may be caught in a tray or receptacle 22 on the loomframe. The full-shuttle in the placer 8"wi1l be picked to the opposite side of the loom. The cain 19 now passes, the placer is returned by its springtoits' normal receiving position, and the shuttle-box descends to its normal position on the lay. As soon as the shuttle-box is elevated the circuit is broken, and the continuedengagement of the 1ever20 with the armature-lever 17 will be purely mechanical.

' .It should be explained that the picker and picker-stick are omitted from Figs, 1 and 2 to avoid obscuring the other parts. The pickerstick plays in a slot in the lay-head and in the bottom of the shuttle-box and also-of the placer when the latter is-on the lay, as seen in Fig. 2. In Fig. 5'the slots for the picker in the respective bottoms of the placer and shuttle-box are shown. Itwill be noted in this view that the fixed side 10' of the shuttie-box has in it recesses 10 to receive the parts 8, forming the corresponding side of p the placer. This side of the placer is short, and a part of the bottom of the placer at '8 '9o is omitted, so that should'the placer be perniitted toreturn to its "normal receiving position before the picker-stick on its return after the pick isfully' "home the stick will clear 'the'placer. -"The' opposite side of the 5 placer-that one at the left in Figs. 1,2, and 5-.has' a movable side 8, which when the placer recedes to its position at the receivingpoint under the magazine is moved outward automatically, so as to widen-the'jpl-acer'and. we

allow ample room for theshnttle to enter freely from the magazine. This'outward movement of the side 8 may be effected by any convenient means. -That herein show-n comprises" a-- lever 23, fulcrumed on the arm 8, the side 8being mounted on the upper arm of said lever. A spring 23" acts to hold said side pressed .in, and a'-s tud.23 on the loom-frame engages the lever below its fulcrnm -aud .presses the' 'side out, as-seen in no Fig. 1:

To prevent the shuttles from falling out of the magazine whenthe placer advances, a device is employed in connection with'the simple uprightlformr of magazine seen inFigs. l 1 g 5 'and 2." Thisv device consists of springs 24 on the. side of the magazine, carrying two fingers 25, which tend to take n nder the coned ends of the bottom shuttl'e and support it; but downwardly-projecting branches -25on the i, fingers 25 are.-engaged by the placer when it recedes, and thus the supporting-fingersare pressed back "by the placer and the shuttle allowed to descend 'into the latter.

Fig. 8 illustrates another form of magazine, 12 5 whichisin mostrespects like that shownin our pendingappli'cation, Serial No. 721,802, filed June 26,1899. It is also illustrated and claimed Within the casing 7 isa rotatively-n ounted drum 7, having at its periphery cells to contain the shuttles. At its top the casing is open, so that the shuttle-cells in the drum may be conveniently filled. The shuttle in the lowermost cell of the drum passes down through the pocket, guide, or chute 7 into the placer. When the placer recedes from the picking position, Fig.2, to the receiving position, Fig. l, a latch 26, carried thereby,

engages one of a series of studs 27 on the end of the drum 7, thus turning it on its axis to an extent sulficient to bring the next shuttle-cell over the placer. When the placer advances, the latch 26 wipes under the stud 27, which it finds in its path. A spring-detent 28 by engaging the studs 27 steadies the drum in its set position.

The electrical devices employed in the shuttie-boa, shuttle, and weft-carrier may be like any one of those shown in our several pending applications illustrating electrically-controlled weft-supplying mechanism-for example, Serial No. 721,802, filed June 26, 1899, or Serial No. 723,128, filed July 8, 1899-or it may be like thosein our Letters Patent Nos. 633,944 and 633,945, dated September 26, 1899. As shown in Figs. 6 and 7, they consist of the instrumentalities which will now be described. On the side 10 of the shuttlebox are mounted two spring-terminals t and These form terminals of an electric circuit comprising the conductors c c, the magnet M, and a suitable generator G. On the side of the shuttle are two contact-plates p and p, which when the shuttle enters the shuttle-box are put into electrical contact with the respective.spring-terminals t and t. Thesh uttle has hinged in it a bobbin-spindle 24, on which is loosely mounted a metal ring 25, which is electrically connected by a conductor 26 (through a spring 27'behind the ring) with the plate 10. The bobbin 28, which slips on the spindle 24 and carriesthe weft, carries a spring-terminal 29, which has electrical contact with the ring when the bobbin is in place, and this spring-terminal tends by its resiliency to spring outward until .its free end is in contact with the inner face of a metal ring or piece 30 on the bobbin. This latter ring is connected electrically bya condoctor 31 with a groovedmetal ring or piece 32 on the bobbin, and when the bobbin is pressed down in the shuttle the said groove engages a metal rod 33 in the shuttle, which is in turn connected by a conductor 34 with the plate 1). The terminal 29 occupies a slot in the bobbin, and when over-wrapped by the weft-thread its free end is held out of contact with the ring or piece30; but when the weft is nearly exhausted the circuit will be closed at this break.

The object in providing the elbow-lever 16 with a hook on its arm to engage the stud 8 on the placer-arm 8 is to permit the lay to vibrate normally without carrying the placer with it and to enable the hook on'the lever to engage the stud of the placer at the-moment of shifting. It would be feasible, however, to couple the. lever 16 permanently to the arm of the placer. \Vhere ahook is employed the cam 19 will be so set as to provide sufiicient movement of the hook to engage the stud before the shuttle box and placer are moved. As the electromagnet M will be excited when the exhausted shuttle enters the box 10 from the opposite side. at the picking-point and the engagement of the hook 16 with the stud 8 must take place at the end of the beating-up movement of the lay, it is desirable to-hinge the end of the arm of the lever 16, hearing the hook 16, and provide it with a spring, as seen in Fig. 1, thus giving it the form of a spring-latch, so that at the moment the circuit is completed at the picking-point tthe cam-lever 20' may engage the armature-lever 17 and begin to rock the lever 16. The latch-hook 16 will then as it approaches wipe over the stud 8 and snap into engagement with the same. As the armature-lever 17 will tend to swing i or turn about its fulcrum on the lever 14 when the hook on its end is engaged by the hook on the end of the lever 20, it is desirable to employ the construction seen best in Fig. 9, which shows the armature-lever on a larger scale than in the principal views. The book 17 a is connected to the lever proper by a rulejoint backed by a spring 17". This spring normally holds the hook rigid with the lever proper; but when acted upon by the lever 20 the spring 17 will yield a little, as will be understood. V

It may be explained, respecting the placer 8, which is made automatically expansible, that one of the objects sought is to have the same contract when the lay recedes to the picking-point, so as to hold the shuttle snugly; and as we are the first, as we believe, to provide a placer that thus expands and contracts we do notlimit ourselves to any specific means and structure for efiecting this result. It will be noted also that the placer is'fullopen at its top, so as to receive the shuttle, which drops in from above.
