Claims. (Cl. 267-1) This invention relates to coiled springs, and more particularly to a vertical eye plate for embracing a coiled spring and connecting it to a hook or other anchorage.

The objects of the invention are to provide a device of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, ornamental in appearance, and very efficient and durable in use.

In the former methods of attaching a coiled wire spring to an anchorage, the end of the spring was usually bent into an integral eye, which not only was a difiicult operation to perform, but the wire of the spring was likely to break off.

By means of the present invention the above and other disadvantages have been avoided, and a flat plate has been provided having an eye formed in one end thereof, and supplied with two rows of drilled countersunk holes on opposite sides of said plate, below said eye.

With these and other objects in view there has been illustrated on the accompanying drawing one form in which the invention may be conveniently embodied in practice.

In the drawing,

Fig. 1 represents a side view showing the appearance of a coiled wire spring when assembled in the improved eye plate attachment. 7

Fig. 2 is a sectional view of the same, taken along the line 22 of Fig. 1, looking downwardly.

Fig. 3 is a sectional view, taken along the line 3--3 of Fig. 2, looking in the direction of the arrows.

Referring now to the drawing in which like reference numerals denote corresponding parts throughout the several views, the numeral III indicates a helical coiled wire spring, th convolueach side of the-spring so as to strengthen the construction and equalize the stresses and strains during use, provision is made inthe lower part of said eye plate I I of two vertical rows of drilled holes I5, IS, IT, and I8, I9, 20, which holes extend horizontally through the eye plate Ii and are located adjacent the'opposite vertical edges thereof.

Each of the drilled holes I5, I6, I], and I8, I9, 20, are countersunk, chamfered, or beveled at their opposite ends, as indicated by the numerals 2| an 22, for facilitating the insertion of the end and convolutions of the coiled spring Iii therethrough, and also to prevent binding of said spring at the inner portions of said drilled holes.

In order to permit the insertion of the coiled spring I 0 into the side holes I5-2Il of the eye plate II, with the minimum amount of effort,

said holes preferably are located close together with the countersunk bevels 2I, 22 touching each other, as shown.

After the coiled spring III has been completely assembled in the eye late I I, the upper end portion 23 of said helical coiled spring IE! will be bent inwardly (as by striking it with a hammer) so that it will lie adjacent to and substantially parallel to the surface I2, as shown in Fig. 2.

' end of a coil-ed spring, comprising a thin plate tions of which normally lie in abutment with each The eye plate II is adapted to be used in the longitudinal position shown in the drawing, embracing the upper part of the coiled spring, and is provided near its upper end with a horizontal aperture I 4 which constitutes an eye for receiving a hook or other anchorage member (not shown).

In order to attach the eye plate I I to the helical coiled spring I 0 at a plurality of points on member having a centra1 eye aperture in the upper end thereof, said plate also having two rows of transverse cylindrical apertures located adjacent the opposite sides of the lower end of said plate for receiving the upper convolutions of said coiled spring, the opposite ends of said coil-receiving apertures being countersunk.

2. The invention as defined in claim 1, in which said countersunk portions are conical in shape.

3. An attaching element for embracing one end of a coiled spring, comprising a rectangular fiat plate having a transverse eye apertu e jacen the end of said plate, said plate also havin two rows of parallel transverse apertures. located adjacent the opposite sides of said plate below. said eye aperture for receiving the opposite portions of the upper convolutions of said coiled spring,

the upper end of said coiled spring being bent inwardly into proximity to one side of said plate. 4. An attaching element as defined in claim 1,

in which the countersunk portions of said side apertures touch each other.

5. An attaching element for embracing one end of a tightly wound coiled spring, comprising a rectangular flat plate having two rows of parallel transverse apertures located adjacent the sides WALTER F. LIBER.
