IMPRovEMNT 1Nl SHUTTLE PoR Loom.

The Schedule referred to in these Letters Patent and making peut of the same.

To all whom it may concern:

Be it known that I, EDMUND F. BUnuows, of Mystic River, in the county'of New London and State of Connecticut, have inventeda new and useful Improvement in Weavers Sl1uttlcs,; and I do hereby declare that the following isa full, clear, and exact description thereof, reference' being had to the annexedtdrawings In shuttles as heretofore constructed, great diii`1 culties have been found to exist from the fact that upon the application thereto of the ibrcerequiredto carry" the shuttle from one shuttle-box to the other, a sudden andvery injurious jar has been imparted to it, in many instances su-tlicient to throw the yarn used as filling from the bobbin or spindle upon which it had been placed, thus causing serious delays and imperfect work.

My invention is designed to remove the objectionable feature above alluded to, or to provide a rem- `edy therefor; and, to this end, i

It consists in providing a weavers shuttle with a metallic point, which receives the blow or shock from the picker which is required to carry such shuttle through the Ywarp of the web to be woven, said point resting at its inner end or rear portion upon a springor some elastic substance, so as to relieve the shuttle to a considerable extent from the jarring effect caused by the impact of the picker.

And the invention further consist-s in the construetion, combination, and arrangementof-the parts of which it is composed, as will he more fully set forth hereinafter. v

, To enable others skilled in the art to make the same,

I submit a more definite description.

A, in the drawings, refersto a shuttle, which may be of any approved construction, it being provided with the usual spindle C for the reception ofthe bobbin, and with a spring for holding said bobbiu in its position.

rlhis shuttle is also provided with the usual tube of this invention, they need not be more particularly described here.

B refers to a metallic point, which is of the usual construction, but which differs from mine in that it is rigidly attached to the shuttle, and has no .movement independentthereof, and consequently 'cannot yield to the impact of the picker.

E refers to a metal tube or cylinder, which may v be of brass or steel or any other suitable material, and may be provided with a screw-threadupon its outer surface for ysecuring it .to the wood portion of the shuttle, or it may be secured thereto byhaving a hole drilled in it and a pin inserted through the wood,

or in any other suitable manner.

This cylinder is to be inserted into a recess or cavity. formed in the wood of the shuttle, as showin in` fig. 1, it heilig provided with a recess in itsrear end for the reception of a spring or some elastic substance, and with a smaller aperture at its outer end through which to pass the point or piston soon to be described.

Frefcrs to a inetalvpoint, which is to take. the place of the xed points usually used, but which is in this case made and arranged so as to have a motion independent to some extent of the other parts' of the'shuttle, for which purpose it is provided upon its inner end with an enlargement, which may be termed a piston, and which moves freely in the larger as shown, or it .may consist of rubber, or any other elastic or yielding material, its oltlce being to receive the impact of the picker, and transmit the force thus received gradually to 'the other port-ionof the sluittle, and thus relieve it from the injurious concussion and jarcauscd by giving it its sudden motion.

I have shown my improvement as attached to only one end of the shuttle, but I contemplate its use uponboth ends.

I do not, therefore, desire to he understood as limiting its application to one or to both ends of the.

shuttle; neither do I wish to be understood as limiting myselt` to any particular form or kind of a spring, or to the material of which such spring may be made,

as lI regard my invention as coveringany and all known forms of springs.

Having thus described xny invention,

What I claim as new, and desire to secure by L'etters Patent, isn 1. A weavers shuttle, having at its Aend or ends n.

point or piston, the movement of which is independf' ent `to the extent described, of the body of the. shut tle, substantially as and for the purpose set forth.

2. A shutt1e-point which receives the impact from the picker or other motion-imparting device, the innerend. of which comes in contact with a. spring or other yielding substance, substantially as and for the purpose set forth'.`

3. The combination and the arrangement of the' cylinder' E, piston or point F, and spring G, substant'lly as and for the purpose set forth.

In testimony whereof I have signed my name to -tllisspecifcntion in 'the presence of two subscribing witnesses.
