GUY ANCHOR Filed Jan. 10, 1930 C. R. Pieper INVENTOR ATTORNEYS Patented Nov. 21, 1933 UNIT STATE testes? rarsNr FFl CE 3 Claims.

My invention relates to improvements in guy anchors, and it consists in the combinations, con structions, and arrangements herein described and claimed.

An object of my invention is to provide a guy anchor in which improvements over my Patent No. 1,123,368, issued February 5, 1915, are enibodied. In the present instance I provide a novel means whereby the anchor which comprises a 1 pair of operatively connected blades in combination with a spreader may be positively spread in such a manner that the blades will be properly centered during the spreading process and effectively associated with the spreader.

A further object is to provide a guy anchor in which means is provided whereby the blades are expanded or opened evenly under all conditions.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing, forming part of this application, in which Figure l is a side elevation of my device showing the blades in their folded positions,

Figure 2 is a side elevation taken at right angles to the structure shown in Figure 1,

Figure 3 is a view showingthe blades in their expanded positions,

Figure 4 is a top plan view shown in Figure 3,

Figure 5 is a sectional view taken along the line 5--5 of Figure 4, and Figure 6 is a sectional detail view taken along the line 6-6 of Figure 3.

In carrying out my invention, I make use of a pair of blades 1 and 2 provided with rib portions 3. The blades are provided with semicircular end portions 4 which are bent outwardly with respect to each other as assembled in Figure 1. Each blade is provided with an enlarged portion 5 having a recess 6 therein. Each bladeis also provided with a laterally projecting trunnion 7 15 which is aligned with its respective recess 6 as shown in Figure 2. It will thus be seen that the blades are pivotally connected together. Each blade is provided with a pair of ribs 8 which is disposed upon the side opposite the ribs 3.

The ribs 8 are curved as shown in Figures 1 and 3 and are provided with a recessed portion 9 whereby shoulders 10 are provided. It will be noted in referring to Figures 2 and 5 that the ribs 3 merge with flange portions 11 of the blades. Each of the flange portions is provided with a of the structure (cries- 92) recess 12, see Figures 2, 4, and 5, which, when the blades are arranged in'their expanded positions as shown in Figure 1, provides a substantially circular opening through which an anchor rod 13 may extend. The blades are curved adjacent their flanges as shown at 11 whereby the blades have centering or aligning engagement with the rod 13 at all times during the movement of the blades from their positions shown in Figure 1 to their expanded positions shown in Figure 3. The anchor rod is provided with a spreader 14'. which is disclike in construction. The rod fits snugly within the opening provided by the recesses when the blades are expanded. The anchor rod may I be provided with a threaded end upon which a nut 15 may be placed for securing the spreader upon the rod. The spreader may of course be secured thereto by any other suitable means.

In Figure 5 I have shown the anchor rod as being provided with a loop 16 permitting the rod to be connected with other mechanism, not shown.

In operation, the anchor is associated with the rod 13 and is lowered into a hole in the ground slightly larger than the diameter of the con- 7 struction. When the mechanism has been lowcred, the blades may be spread by tamping thereon with any suitable tamping tool, preferably a tool of bifurcated construction. It will be seen in viewing Figure 1 that when the blades are driv- I en downwardly, they will be caused to spread by reason of the spreader 14. The blades are therefore embedded in the earth, and, when completely expanded as shown in Figures 3 and 1, the spreader will be disposed within the recesses 9 in the ribs 3, whereby the edges of the spreader will engage the shoulders 10. Such engagement will positively hold the blades in their expanded positions, whereby the rod 13 will be efiectively anchored in the earth. An important feature in connec- A tion with my invention is the fact that the blades are provided with the flanges 11 and their associated curved portions 11 which engage the rod 13 during the spreading process. The construction is such that the blades are perfectly centered when the latter are being driven into the earth. The blades in being properly centered during the spreading process are positioned so that the shoulders 10 will always be properly aligned for engaging with the spreader 14. Thus it will be seen that the blades will always be locked in their expanded positions when they are driven into the earth. The recesses 12 form an opening conforming to the diameter of the rod 13 when the blades are expanded.

In Figure 6 I have shown the ribs 8, associated with each of the blades, as being provided with a connecting portion 12 having a recess 12". The recesses 12" receive the rod when the blades are collapsed as shown in Figure 1. The construction is also such that the blades may be easily and quickly disconnected or operatively connected whenever desired.

I claim:

1. In an earth anchor of the type comprising a spreader plate and a longitudinal rod extending upwardly therefrom, and blades having contact faces on their under surfaces for engaging said spreader plate when said blades are forced down upon said plate to guide said blades into expanded position whereby the blades enter the earth edgewise, heel portions carried by said blades and closely encircling said rod throughout the expanding movement, whereby the path and angularity of each blade is predetermined in all positions.

2. In an earth anchor of the type comprising a spreader plate and a longitudinal rod extending upwardly therefrom, transversely pivoted blades adapted to enter the earth edgewise, when forced down and out, contact faces on the under surfaces of said blades for engaging said spreader plate when said blades are forced down upon said plate to guide said blades into expanded position, said blades having also portions closely encircling said rod throughout the expanding movement, whereby the path and angularity of each blade is predetermined in all positions.

3. In an earth anchor of the type comprising a spreader plate and a longitudinal rod extending upwardly therefrom, blades pivoted to each other on a transverse axis substantially intersecting said rod and adapted to enter the earth edgewise when forced down and out, contact faces on the under surfaces of said blades for engaging said spreader plate when said blades are forced down upon said plate to guide said blades into expanded position, said blades having also portions closely encircling said rod throughout the expanding movement, whereby the path and angularity of each blade is predetermined in all positions.
