No. 892,472. PATENTED JULY 7, 1908.

- S. M. WALKER.

GAPB WORM EXTRAGTOR.

APPLICATION FILED FEB. 2a. 1908.

1 6 m. p y/Q2 animator autumnal! SADIE M. WALKER, OF LAUREL, INDIANA.

GAPE-WORM EXTRACTOR.

Specification of Letters Patent.

Patented July 7, 1908.

Application filed February 28, 1908. Serial No. 418,241.

To all whom it may concern:

Be itknown that I, SADIE M. WALKER, citizen of the United States, residing at Laurel, (R. F. D. No. 1, Box 53,) in the county of Franklin and State of Indiana, have invented certain new and useful Improvements in Gape\/Vorm Extractors, of which the following is a specification.

My invention consists of an improved instrument for the removal of worms, mucous and other obstructive matter from the throats of fowls and which produces the complaint commonly known as gapes, and it has for its object the production of an instrument for this purpose which can be readily used by persons having but little experience in the raising or care of poultry, and which shall be inexpensive and effective for the purpose for which designed.

In the accompanying drawing constituting a part of this application Figure 1 is a View in elevation of the lnstrument and Fig. 2 a similar view of a modified form thereof.

1 designates the stem or body of the instru ment made from a number of strands of fine wire twisted together. These are preferably four in number, and the lower end of the stem or body thus formed is bent back upon itself and incased in a covering of lead to form a handle 2 for the convenient holding of the instrument.

At a point near the upper end of the stem the wires constitutin the stem are separated and bent outwardly forming loops 3, beyond which the separated wires are again twisted together as at 4, thus closing the upper ends of the loops 3. Beyond the point 4 the wires are again bent to form a loop 5, thereby forming a blunt end to the instrument to avoid perforating or otherwise injuring the throat of the fowl in the use of the instrument therein.

In Fig. 2 is shown a modified form of construction in which the stem 1 is made of but two strands of wire and but two loops 3.

In the use of my improved instrument it is inserted in the throat of the fowl and revolved therein by the fingers grasping the handle 2. This causes the worms, mucous and other foul matter to be caught between the wires forming the loops 3 and to be gradually wound in a mass therein when it can be readily and quickly withdrawn.

The instrument is light and the wires of which the same is made are soft and flexible,

thereby avoiding all danger of injuring the throats of the fowls undergoing treatment. As the forward end of the instrument is made in loop or blunt form all danger of perforating the membrane is avoided.

While I have described herein and illustrated in the accompanying drawing the preferred embodiment of my invention, I do not wish to be understood as thereby limiting the same, as various changesmay be made therein without exceeding the scope thereof.

I claim 1. In a gape worm extractor, a number of thin wires twisted together to form a stem and separated near the upper end of the stem and bent outwardly to form loops, said wires being again twisted together beyond said loops, whereby the ends of the loops are closed, as set forth.

2. In a gape worm extractor, a flexible stem composed of thin wires twisted together, a looped section in said wire intermediate of the twisted portions thereof, a looped portion at the upper end of the stem, and a handle on the lower end of the stem, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

SADIE M. WALKER.
