Application med iebruary 24, 1913. Serial No. 750,232.

' b all whom it may, concern:

ed a certain new and useful Improvement in Grourid-Anchors, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawlugs, forming part of this specification, in which- Figure 1 is a vertical sectional view through my improved ground anchor. Fig. 2 is a top plan view of the same. i

This invention relates to new and useful improvements in ground anchors, the object being to construct a device of the character described which may be of letaehable units whereby the size of the anchor may be increased or diminished according to the holding power required.

In the drawings, 1 indicates the rod which extends to or above the surface of the ground, and to which is connected the guy rope or cable. This rod has a not on its lower end by which it is connected to the section 2 of my improved This section 2 is preferably in the form of the frustuni of a cone and is provided with an: outwardly extending-flange 2 at its base The sides of the cone are provided with projections or lugs 2".

3 indicates a. tapered ring having an inwardly extending flange 3 atits upper edge, said flange having notches 3 which are designed to register with the lugs 2 of the section and by slightly turning the section 3, locking the same against longitudinal displacement to the lower edge of section 2. Section 3 also has an. outwardly extending flange 3 at its lower edge and lugs 55 for the purpose of codper ting with the notched flange of the next 5 1'. ;n. of increased diameter as shown in the drawing. There is also shown in the drawing another section 5.

Additional sections of gradually increasing diameter can employed until the desired base diameter of the anchor is secured. In practice, I have found that the majority of ground. anchors used range from 'Z to 13" in diameter and inpractice the top unit or and notches on said ring sect-ions,

section 2 would preferably be made 7" in diameter across the bottom whereby this single unit could be employed for ground anchors of this size. To increase the size of the anchor, a tapered ring would be secured to the top unit or as many rings as would be found necessary to secure the required diameter. v y

It will be observed when a single unit is employed or a plurality of units are used,

that my improved anchor is tapered or is essentially conical in shape having shoulders or projections in the form of steps, which shoulders or projections add materially to the holding power of the anchor. v.In practice, after the hole is dug, it is usual to tamp stones in around the anchor, the upper portion of the hole being filled in with dirt. The stepped shoulders engaging the stones not only offer great resisting power against a pull on the rod, but the conical shape tends to force'the stones laterally, and this wet ging action also offers great resistance to dislodgment of the anchor. i

it can be shipped collapsed and occupy-"'5' very small space, or when quantities are packed for shipment, the various sizes of rings may be nested one within the other so as to occupy little space in hipment.

What I claim'is: 1. As a new article of manufacture, a

"ground, anchor comprising a series of tapered ring sections which are graduated in size so as to form a hollow conical body when properly assembled, which ring be readily assembled or taken apart to vary the diameter and height of the anchor, nu

sections can means comprising coiiperating projections for bolding the same in open position.

2. As a new article of manufacture, a ground anchor, the main body portion of which is composed of a series of collapsible members, each of which comprises a ta ered ring section, an inwardly projecting ange on the upper edge of each section, there being a notch formed in said flange,'an outwardly projecting flange on the lower end of each section, an integral projection on each sectionadjacent to the flange on the lower edge thereof, which projection is adapted to I tapered ring 10W truncated conlcnl 5 connected to the upper tepofthe next i1 ring sections, to said holl sectlons 111 pass through the notch. in the flangeat the djncent sections to lock said open pesition, a holmember detachably one ofthe series of and an anchoring rod attached w COIllCfll member.
