` Be it known thatI, LARoY LITCFIEED, of

` l Southbridge; in the county of Worcester and State of `Massachusetts,' have invented certain new and useful Improvements 1n `Shuttles for Looms; `and I` do hereby declare that the following is-a full, clear, and exact description of the Same, reference being had to y the accompanying drawings, forming part of this specification, in which- Figure `1,is allongitudinal section of a shuttle constructed according to my invenwhich is coiled the spring which keeps the Spindle 1 lli y pltCe.f t Fig; ,37j is an underside gviewl oftheshuttle.v 1

`2b` 1;" place, which `admits of therepeated raising t and replacing of the spindle to renew` the This invention consists in a novel inode of applying `a spring to keep the `spindle in yarn, without causingany wear of such a nature as zto throw `the spindleout of place.

` `ais'the spindle and b, thepin which t fastens it in the shuttle,` Thehole which receives the pin b, is placed a little lower than the axisjof the spindle and the Spindle "is extended some distance behind the` said 1101. Theparwofthelspindieso extended,

whichulnay be" termed `the heel, is inclined `downward from the pin b in order to make `room forthe coiledspring d, which holds "the spindle in itsplace. `This spring cl, is

f coiled around `aV pinje, `whichvts with a knuckle f,\to the back-part of the spindle.

alittle higher than the `spindle a, and'is compressed `between a Shoulder in rearof t the lmuckleand "a suitable bearing in the body A oftheshuttle. `f Fhepin e, when the spindle is in its` operative position as shown in black outline in .Fig.l, stands nearly in t `line with the spindle, `and the spring d, by

" exertingits forcefabovejthe lpin Z), throws up the heelof` the spindle against a bearing `in `thebody of the t shuttle and holds the spindle firm.` `Thi'sbearing may be formed Win the `body `of the Shuttle, but I prefer to usethe headofthe regulating screw h, for

which, it receivesthe cop or bobbin.` l When f the Spindlefis inthe last named position the knuckle f stands below, thejpinlb, and holds the spindle against a bearing at t', Ain the upper part of the body of the shuttle.

j, the spring catch which connes the bobbin. This is attached to the heel of the Spindle and thrown ott' the bobbin when the point yof the spindle is raised, by coming in contact with a stationary transverse piny la, placed below and in front of the pin b, and in these respects resembles the spring of the Shuttlefor which Letters Patent were granted to` me on the th of September 1851; but the pin c, is so placed that the spring will not, while'` a bobbin is on the spindle, come in contact with the said pin untilthe point of the spindle is raised some distance, and therefore it will hold equally well a large or small headed bobbin without interfering with the firmness of the spindle,

while if a very large headed bobbin be n placed in my other shuttle it takes oli thev pin k the pressure of the spring'which is necessary to hold the spindle secure. The same difficulty with regard to a large headed bobbin is `common to other shuttles.

In this shuttle the firmness of the spindle is in every way provided for.` The length of the heel c, is such that it prevents lateral play of the ypoint of the spindle. The spindle cannot get out of place by wear on the spring which holds it as it will in other shuttles. A new spindle can be inserted readily and at once adjusted by the regulating screwh.

The shuttle can be as cheaply constructed as my other shuttle or as Inostother good shuttles lasthe spindle, or all the rear part "of it and the pin e, may be vmade of malleable cast "iron, and the spring 7' of light steel plate riveted to the heel of the spindle.

7 The oop shuttle would `only diiier from` y that represented, in `the absence of any spring j. What I claim as ymy invention and desire to secure by Letters Patent, is-

The backward extension of the heel c, ofthe spindle as described combined with the application ofthe spring d, above the said heel, and above and in rearof the pin b,
