THOMAS R. ELLIN, OF SHEFFIELD, COUNTY OF YORK, ENGLAND.

POCKET-KNIFE.

SPECIFICATION forming part of Letters Patent No. 360,866, dated April 12, 1887. Application tiled July 30, 1886. Serial No. 209,598. (No model.) Batcuted in England April S, 1886, No. 4,909.

To @ZZ whom it may concern.:

Be it known that I, THOMAS RIoIIARDsoN ELLIN, a citizen of Great Britain, residing at Sheffield, in the county of York, England,

have invented certain new and useful Improvements in Spring Cutlery and other Similar C losi ng Articles, patented to me in Great Britaln by Letters Patent N o. 4,909, dated April 8,1886; and I do hereby declare that the fol` lowing is a full, clear, and exact description thereof, reference being had to the accompany- Ing drawings, which form a part of this speciication.

This invention refers more particularly to one-ended pocket-knives-that is, to knives in which the blades are pivoted at one end only of thehandle, the chief object being to reduce the cost of manufacture, while increasing the strength of the article.

The method of carrying my invention into effect is shown in the accompanying drawings, in Which- Figure I represents a complete single-blade knife and separate parts of same. Fig. 2represents a double-bladed knife and button-hook in section and complete; Fig. 3, a knife with closing button-hook and blade; Fig. 4, gardeners budding-knife according to my invention.

In making a singlebade knife, as shown in Fig. 1, for example, I take a strip of any suitable metal and shape it to the formshown at A. I then bend or double it back in the middle to forni the two scales, as shown at B and the end of the spring E to project sufficiently to take a bearing against the edge of the metal,

as seen in the complete knife.

The end-of the spring may be finished off i.

ush with the end of the knife, or it may pro- 40 ject and be utilized as a turn-screw, F,.or other CO u The metal scales may constitute the outside of the knife, or outside scales of ivory, horn, or other substance J, Fig. 3, may be attached thereto.

When a divided or lobster spring, E2, is used-as, for instance, in a two-bladed knife, as shown in Fig. 2-instead of making a notch 0r opening, D, at the side, it is made through the center, and the projecting end of the spring may be utilized as a button-hook, and is pinned through at G. If preferred, it may be cut off flush with the end ofthe knife.

In the case of a budding-knife7 (shown in Fig. 4,) having an ivory handle, K, slit through the solid to receive the blade and spring, they are very liable to fracture when made in the usual ,way My invention obviates this, as the double scale with the blade is inserted bodily into th el slit, and can be secured by pins passed through the thickest parts. The strain of the spring is also taken from the ivory and is borne by the scales. Y

Fig. 3 shows an arrangement of button-hook and blade', the end of the spring E2 being used as an attachment for a split ring to fasten a cord to.

In each of said improved articles the metallic scales of the handle are in a single piece, adapted to be readily formed, and having a single short transverse bend. The head77 end of the spring is solidly supported, the separation or displacement of the spring is prevented, and the blades may be as long as the scales.

I am aware that a pocket-knife has before been made with its metallic scales united by a longitudinal bend. This I disclaim as formingrno part of my invention.

\Vhat I claim as my invention, and desire to secure by Letters Patent of the United States, is-

In a pocket-knife or similar article, the combination, substantially as herein specified, of a spring having a single pin-hole, a pair of metallic scales united at the head end of the handle by a transverse bend, and having an opening in said bend occupied by the head end of said spring, a folding blade or the like pivoted between the scales at the opposite end of the handle, and a pin which securely unites the scales and spring, for the purpose set forth.

In testimony that I claim the foregoing as myA own I have affixed hereto my signature in presence of two witnesses.

THOS. B. ELLIN. Witnesses:

BORT. F. DRURY, ENsoR D. DRURY.
