IMPROVEMENT IN'l 4IEIIl'.|Il|I1\l'(L|-IORIKS FOR LOOMS.

. 4 The Schedule referred to in these Letters Patent and making part ofthe same.

To all whom c'tmay camera:

Be it lmown that we, WILLIAM G. DUGE, of Baltic, in the county of New London, and State of Oonnecticut,- andALBER'r O. EDDY,- ofthe city ,and county of Providence, in. the State of Rhode Island, have invented' certain new and vuseful Improvements in Filling-Forks for Looms; and we do hereby declare that the following 'specicatiom taken in' connection with the drawings making a part of the same,I is a full, clear,

and exact description thereof.

In the drawings, our improved lling-fork is shown in perspective. Y v

A filling-fork? is a device commonly employed in a power-loom, by means of which, in case the weftthread given oli' by the shuttle chances to break, the driving-belt is made to shift from thejfast to`the 'looser pulley, andthe .loom is thereby stopped. The' device in its application to the loom is variously p bell-crank lever, hung in bearings, so that'it can vibrate freely.` Its largerarm is slightly heavier than its shorter or forked arm, and is furnished at its extremity with a projecting catch, which catch, when permitted to lock with Y the end 'of a, vibrating lever, will communicate motion, through appropriate de'vices, to the belt-shipper. The shorter or forked end of the bellfcrank is so arranged in position relatively to the layffiame that at each forward beat of the latter, the prongs of the fork will enter the spaces between the gridiron-bars in the layfframe.

If the thread of weft which has been discharged from `the .flying shuttle is unbroken, itfwill be stretched taut across-the space between the bars of the gridiron, and the front surface ofthe prongs, in entering such spaces, will bear against the thread, whereby the longer arm of the bell-crank will be kept sufficiently elevated to prevent the catch upon its end fromfallingjnto engagement'with the leverwhich controls the beltfshipping apparatus.

In the accompanying drawing, a common form of fork is shown. v t

The ,portion A -is made of! India. rubber, and is in form like the metallic forks in common use. It is attached to the portion B, which is made of metal, by means of a socket, a, in which, by set-screws, b, or other convenient'means, it is secured. i

To prevent the threads ofthe lling from cutting into the prongs, the latter are covered fora short distance, near their tips, with shields of very thin-sheetmetal, c c.

' What we claim as our invention, and desire tosecure by Letters Patent, is4

The combination, with the -lling-fork, having tines of India rubber, or other flexible and elastic material, of the protecting metallic shields c c, substantially as described. v Y
