IMPROVEMENT IN SURGEONS NEEDLES.

Specification forming part of Letters Patent No. 221,638, dated November 11, 1879; application filed July 21,1879.

To all whom it may concern:

Be it known that I, JOHN WATSON, of the city of Utica, county of Oneida, State of New York, have invented certain new and useful Improvements in Surgeons Needles; and I do hereby declare that the following is a full, clear, and exact description'of my invention. which will enable others to make and use the same, reference being had to the accompanyone end sharpened and the other out square A hole is boredjat the latter end longitudinally into the Wire by a suitable drill or tool placed in the center of the straight out and continued any required distance-say, oneeighth of an inch, more or'less. Through the side of the needle, at a distance from the straight out corresponding to the length of the said hole, is transversely bored 2. second hole by a suitable tool or drill, thus penetrating the wall of the hole in the needleyand causing the The tool or drill for the tir'sthole may be so formed that'ihis hole in the center of the needle will be a true oylindricalbore, or they may be made to produce a conical bore, as may be desired. The second hole, also, may be of any desirable bore, and the angle formed between-the axes of the boreslof the two holes may be right or obtuse. The side hole is made with beveled walls, or a countersink, so as to catch and hold the knot in r the thread while the knot is yet below the surface of the needle, thus facilitating the stitching at the same time that the thread is held securely in the needle.

When a thread of any required material, such as silk, cotton, or linen, is to be used, a knot is made at one end of the thread, and the otherend, being pointed, isintroduced through the hole in the side of the needle, and pushed through the hole in the center of the needle, is caught at the pointed end by the fingers, and drawn out until the knotis snugly embedded in the hole in the side.

The needle can be operated with like an ordinary needle.

Referring to the drawings, in order to explain my invention more fully, Figure 1 is a side view of my improved needle with-thread attached. Fig. 2 is a longitudinal sectional view, and Fig. 3 is a top View, of the same. Fig. 4 is a section, showing the countersink in the horizontal hole.

A is the needle, with the pointed end I). O is the hole in the top and through the center of the needle. 01 is the hole in the side of the needle. E represents the thread with the knotted end g.

The shape of the needle may be either straight or curved, according to requirements.

When, instead of a fibrous thread, a wire is used, the latter may be knotted by fusing a head on its end in a flame.

I am aware that needles have been made somewhat similar to mine, one having side
