STEEL SPRING-Bow.

Specification of Letters-Patent.

Patented Nov., 23, 3l9ll5.

Application filed May 17, 1915. Serial No. 38,728.

To all whom t may concern.'

Be it known that I, EBEN F. ExNos, Jr., ad citizen of the United States, residing at Salem, inthe county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Steel Spring- Bows, of which the following is a specification.

My invention relates to improvements in steel spring bows which maybe used as a toy or amusement device, or vwhich may be capable of service in archery by increasing the size of thebow.

The object of the invention is the provision of a bow constructed of spring steel and from a single piece to produce a thoroughly efiicient, inexpensive and practical article of this character. I

Another object of my invention is the provision of a bow made from asingle piece of spring steel wire, with the spring por-- tion of the bow disposed in position to provide a handle or grasping portion andto insure the greatest and most uniform spring action to the bow.

With these objects in view, the invention broadly stated consists of ay bow comprising a central coiled spring portion adapted to form the handle and spring of the bow and having its terminalv forming the arms' of the bow which receive the connecting cord or wire.

The invention further consists of a steel spring bow embodying a novel construction and arrangement of parts, substantially as shown, described and claimed.

Figure l represents a side elevation of4 a steel spring bow constructed in accordance with and embodying my invention, showing in dotted lines the manner of drawing the bow. F ig. 2 represents a sectional view on line 2 2 of Fig. l. and Fig. represents a view in elevation showing the spring portion in section.

The bow is constructed preferably of steel spring wire of the proper size and consists of the main centrally disposed, closely coiled spring portion A, having its terminals extending from each end to provide the pair of spring bow arms B, formed with hooks C, to receive the drawing wire or cord D, which construction disposes the Vspring portion A in proper position to provide a perfeet handle or grasping portion, and to impart to the arms B a great amount of elas.- ticity or spring action to insure the bow a strongpropelling or projecting action to the arrow or missile, and at the same time evenly distributing the action of the spring to insure absolute accuracy in the use of the bow.

It will be understood that the bow may be made in any size according to .circunr stances, and also that the driving spring may be covered if desired and that the article -iS of extremely simple and durable construction and can be produced at a very smali price.

I claim: i

1. A steel spring bow, consisting of a centrally disposed spring coil, having its terminals forming spring bow arms, and a drawing cord or connection for said arms,

said spring coil having its convolutions disposed vertically with reference to its terminals and fitting snugly togetherto i'orm a grasping portion and provide the greatest degree of elasticity.

2. A steel spring bow, consisting of a centrally disposed spring coil forming the grasping portion of the bow, and having its terminals forming spring bow 'arms terminating in hooks, and a wire connecting said hooks and forming the drawing device for the bow, said spring coil having its con"-y 'volutions disposed vert'ally with reference to its terminals and fitting snugly together to form a grasping portion and provide the greatest degree of elasticity.

In testimony whereof Laii ture in the presence of .two witnesses.
