Description

En L. rninmcn y c RIsrorHERiLgFRINK, of Rock ville,1in tliecounty of'lollandaud State of Connecticut, have inventeda certain new i and useful Iniprovementin Shuttles forWeaving; l and I do herebydecla'rethefollowing to i be a full and] exact descriptionof the same,`

k reference being;` had to `the accompanying "drawings, makingp ofthisspecication, in `wvhich" 1 Figurel isa sideelevation of the 'complete shuttle. Figi 21s a longitudinal section of one end of the same FigLB is a similar view withoutthe tip;` ,before the insertion of the metallic :ferrule Fig. 4 is asiinilarview with theferrule applied and the tip readyto wdrive, as hereinafter described. FigiY 5 isan endview illustrating ytlie` application of the i invention to a shuttlewhich has been split.

Similar letters of reference indicate corre- `spending parts `in the several views. y It is well `known thatgreat difficulty is ex- "perienced `from the liability of shuttlesto split by the metal tip or pointstrihing anyvhard `substance when the shuttle is thrown out of the loom; also, A it `frequently happens thatin i enteringwthe shuttle-box the shuttle will strike f on` the mouth of fthe;` box, thereby loosening the point andfsplitting the shuttle. In either `1 case ashuttlef of fcommon construction is renntirely useless bythe accident named., objectof my invention is to so construct `sh ttle` that it cannot split in consequence of e violence referred to, and also to provide a meanswh `bya shuttle of common construcltion vvjhiclrhas beensplit may be repairedand `rendered thoroughlysound and good.`

. To enable others skilled in the artto which my invention `pertains to` -fully understand and use the same, I wil oceed to describe it and explain'the`m`an carrying it into effect.` The mainjbody c fthe shuttleis formed of wood, andmay be of `common construction, with `the exception its ends.` c 3 I B B arethemetal point-s, formed `ith shanks 11b, which are driven into holes a in the center of each end of thelshuttle in customary man ner. w i C is an annular cavity or groove@ which is formed-1in each end of the shuttle concentrically aroundthe central-hole, a, andfabout equi- Vj'EjMeNTIN wsvRs= .sHUrTLEs- RCCKVILLE, CONNECTICUT.

- D isa ferrule, of brass, iron, or" other metal,

formed and adapted to accurately fit the cavity G. The said ferrule is made accuratelyr cylindrical on its exterior. `taper very slightlyfrom the `front backward, or may be cylindrical for the greater part of `its length; but at the extreme rear end it is ireamed orbeveled out, asclearlyshown in Figs. 2, 3, and 4, so as to form a circular edge of diameter equal with the' external diameter lof the ferrule. rlhe object of` this peculiar `construction will be shortly eXplained.- i

The manner of carrying out my invention sin the construction'of a new shuttle is as fol- .A

lows: lThe wooden part A of the shuttle being constructed `in customary manner, and the cavitiesu and G formed in its ends, the ferrule Dis first inserted and driven home, and the tip B afterward. In the case of a shuttle of common construction having been split at either end, the metal tipis taken out and the fractured end of the shuttle being (ifnecessary) temporarily compressed and held together, the annular cavity G is produced in the same way as with a new shuttle. The ferrule is then inserted in the manner before de-A A scribed, and the metal tip replaced. The shuttle will then be capable of resisting manifold more violence than when it was new, and will be equally efficient for use. c

It will be observed that the construction of the ferrule is such'as to preclude all danger of splitting the shuttle in the act of its insertion. The circular, edge in frontof the ferrule being fof equal diameter with every part of the exterior, prevents any expansive action and causesthe pressure to be exclusively inward.

rIhe use of the invention renders it impossible for the end of the shuttle to split while in use, or with any accident or violence to which it is subject.; and the manner of inserting the fer- `rule beneath the surface does not interfere l with the needful smoothness of the joint between the wooden body of the shuttle and the metal tip.

In applying the ferrule to a shuttle of common construction which has been split, the

`distantbetween115mm,the circumference of @he 'e115- Ofathe Wood.,` 3

curred.

Its interior may An additional advantage of my invention is the protection afforded against the splitting of the ends of the shuttle in the act of driving the tips. By this means the shank b can be made to fit much more tightly without danger 0f injury to the shuttle, and the great inconvenience 0f the shuttle-points becoming loose is thus entirely overcome.

From the foregoing description it will be understood that the present improvement is intended to apply to Shuttles in which the metal tip is attached by means of a central shank. One superiority of such shuttles over those in which the metal tip constitutes a cap inclosing the wood consists in their non-habit ity to Work loose with the eudwise concussion to which the shuttle is constantly subjected While in use. The cap must be secured by screws, pins, or'other lateral fastenings. These hold the tips as much from'being driven on as from coming loose, and consequently as the metal expands and the Wood Wears the cap becomes loose, and its edges and the heads of the screws project so as to catch upon the yarn While the shuttle is in use. The shanked tip,

on the contrary, being held by compression Within the wood, becomes tighter and tighter as it is driven in, and has no tendency to work loose with regular use, nor are any projections formed to catch the thread. The shanked tip, therefore, possesses great superiority; butsh uttles of this kind as formerly constructed have been subject to fatal injury from alateral blow uponv the metal tip, splitting the end of the Wood in which the shank is inclosed. This disadvantage is entirely overcome by my invention, for, inasmuch as the splitting of the wood, can only occur by the lateral pressure of the shank, the ferrule having suii'icient strength to resist this pressure e'eetually preserves the wood from injury. This is true as Well in the case of a shuttle which has been split as with one to which the ferrule is originally applied. lWith a split shuttle the ferrule will hold the fractures together completely to the outside by the natural cohesion of the wood, and `:vill also sustain any lateral pressure which can be produced by the shank, and thus protect the existing fractures from any violence which would cause them to open.

I claim as my invention and desire to secure by Letters Patent- As a new article of manufacture, a shuttle provided at its ends with shanked metal tips B and metallic ferrules D, the latter tting within annular cavities C beneath the surface of the Wood, and all constructed, combined, and arranged `in the manner and for the objects set forth.
