Specification of Letters Patent.
Patented its. 7,1906.
Application filed April 20,1905. Serial No. 266,601.
To all whom. it may concern:
Be it known that I, FELIX ODQNNELL, a citizen of the UnitedStates, residing at the city of Pawtucket, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements in Shuttle-Positioning Devices for Looms, of which the following is aspecification, referencebeing had therein to the accompanying drawings.
This invention relates to a shuttle-positioning device, and has for its objectto-produce a device that will engage and force the shuttle completely into the shuttle-box when a small amount of it projects therefrom and place said shuttle exactly in the required position in the box.
A further object of the invention is that if for any reason the shuttle only partly enters the box and is not in far enough to be acted upon and moved further by a positioningarip then theshuttle as it is being brought 1 forward on the lay will engage said arm and force it backward and through suitable mech-' anism throw off the operatmgdever and stop the loom.
1 It is found in practice that when the shuttie is thrown across the lay it is not always sent with a uniform velocity for various reasons-sometimes it does not entirely enter the box and sometimes .it enters with\ considerable force and rebounds therefrom. In
the operation of weft-replenishing mechane ism on the looms it is of vital importance to the successful operation of the same that the shuttle should be in a position exactly beneath the bobbin-holder'whenthe mechanism operates to sti'if ge a bobbin down intothe same. Also "in the/operation 'oftheordinary loom itpis foundthat the loom operates to much better advantage if the shuttle is well back in the box with one end resting against lay, the breast-beam of a loom, and the shuttie in'the shuttle-box, also showingthe'positioning-arm and the mechanism operated I thereby to stop the loom whenit brings up positively against the side of the shuttle. Figs 2 isaplan view showing a portion of the i view, partly in section, showing the latch-- bolt and its connection to the rocker-shaft;
- Referring to the drawings,'at 1 is the usual loom breast-beam, broken away at one end to better show the mech anismbeyondo; At 2 isthe usual loom-operating lever, thet'extends up through. said beam and worksin theslot 3. A portion of the lay is shown at t, and a.
portion of the shuttle ,5 is shown in the shuttie-box 6, with its ends 1 projecting slightly out of the same.
At 8 is the positioning-arm, which is set at right angles to the breast-beem and is hung tobe moved endwise in bearings 9 and 10,
supported from said beam. The stiff coilspring 11 is wound around one end of this arm, one end of said spring being-1n contact with the bearing 10 and the opposite pressing against the shoulder 12 on'said grin, normally holding the'sanie in itsoutward position against the stop-pin 13. On'the contactend of, this arm is the shoe 14', that is faced with leather or other suitable material 15. This is designed to eng'agethe tapering end of the shuttle, (if said end. shouldproject beyond the box as said shuttle is b e-;
ing brought forward by the lay,) and by suclr engagementforce the shuttle lllW'BJd to its required position. ,On the underside of the armBis the recessed portion 16, which is pro VldGdflYltlLiL notch. 17.
Connected. to the rocker-shaft 18 is tlre guide-collar 19, in which i if collar. the latch-bolt 20 works and is normally held in its outward position against the said arm 8 by the tension of the coil-spring 21. At 22 is one of the bearings that supports the rocker-shaft beneath the breast-hea1n, and at 23 is the knmik ofliiinger mounted on said shaft. This finger has one end extending upward to engage the arm 24, through which arm the operating-lever 2 is thrown oil. The operation oi the device may be further described as follows: W hen the shuttle is thrown across the loo1n,itis supposed to enter the shuttle-box, where its velocity is checked by various means and to stop in a given position with its end resting against the picker-stick; but 1t is found in practice that the shuttle does not al 'ays do this. Sometimes it enters the box too fast and rebounds therefrom, leaving the end projecting slightly, and sometimes it does not quite enter the box, in both of which cases it should be carried forward to the required position. The positioning of the shuttle is especially necessary on a loom equipped with weft-relenishing-mechanism in which. a. bobbin is 'ield in a given position to be struck down into the shuttle. -It is obvious that by the use of this mechanism the shuttle must be in aposition directly beneath the bobbin in order to receive said bobbin from its holder. In order to be sure that the shuttle is carried to its proper place each time. on the replenishing end of the loom, l have located the ositioning-arm 8 on the breast-beam and placed behind it a spring of snllicient strength to yield only when said arm strikes squarely against the side of the shuttle. This arm is arranged to engage the beveled end of the shuttle (ii the same is projecting from the shuttle-box) said shuttle is being brought -forward on the lay and by such engagementmove said shuttle inward to its required position in the box to a point. directly beneath the bobbin to be delivered therein. Should the shuttle be-extel'lding out of the box too far when brou ht forward on the lay, so that the arm coul not engage its beveled end, then the side of said shuttle would strike against the arm and force it backward against the tension of its spring 11, causing the notch 17 to engage the latch-bolt 20, turn the same back, rotate the rocker-shaft, and by the movement of the finger 23 fxedithereon the operating-lever is released and the loom stopped.
The device is extremely simple in construction and eflective in its operation and may be readily attached to any loom.
Having thus described my invention, what Ielaimi as new, and desire to secure by Letters Patent, is-
1. A device of the character described comprising an arm or member for engaging i the shuttle as the latter is moved forward 1 with the lay of the loom, and means carried by said arm for yieldingly holding the same in a normally outward position.
.2. A device oi" the character described comprising an arm or member provided at one end with a. shoefor engaging the shuttle as the latter is moved forward with the lay of the loom, and means carried by said arm for yieldingly holding said shoe in anormallyout ward position.
3. A device ol' the character described comprising an arm or member for engaging the shuttle as the latter is moved forward with the lay of the loom, and a spring carried by said arm for yieldingly holding the same in a. normally outward position.
4. A device of the chznacter described comprising a slmttle-engaging arm mounted in bearings, and means carried by said arm tor yieldingly hoiding the same in a normally forward position.
5. The (mmbination with a longitndimtllyreciprr :ablc arm or member arranged to intercep. a projecting portion of a shuttle as the latter is carried forward by the lay of the loom, and means carried by said arm for holding the same in a normally outward position, of means for stopping the loom when said arm or member yields to the movement of said shuttle.
6. The combination with the brcast-bmnn of a loom of an arm or member for engaging a projecting portion of a shuttle as the latter is moved forward by the lay of the loom, a spring for holding said arm or member normally forward, a shaft mounted adjacent said breast in engagement with said nrst-mentioned arm or member, whereby said shaft'will rock when said arm or member moves against the action of its spring, and means controlled by said shaft for stopping the loom.
In testimony whereof I ailix my signature in presence. of two witnesses.
