DDDQUDDUUU United States Patent 3.491,985 POST ANCHOR Gail Grimsley, Rte. 3, Creston, Iowa 50801 Filed Nov. 21, 1968, Ser. No. 777,614 Int. Cl. E04h 17/02; Bllf 27/00 U.S. Cl. 256--47 9 Claims ABSTRACT OF THE DISCLOSURE A conventional fence post with a rigidly mounted stabilizing anchor plate is provided on the extreme lower end with an added foot-type anchor. This added anchor functions to hold the post down and against displacement where the wires of the fence bridge over ditches and low lying uneven terrain. This added anchor has a plate portion projecting below the bottom edge of the post. The outstanding vertical edges of the plate portion are provided with upper and lower pairs of laterally directed fluke-like holddown wings.
This invention relates to a conventional-type fence post, either wood or metal which, as is commonly the case, is provided upwardly of its lower anchorable end portion with a flat-faced anchor plate and is herein unique and distinct in that the extreme lower terminal end is structurally and functionally improved by the addition thereto of a unique foot-type earth cleaving, holddown and stabilizing anchor which is complemental to the above named anchor plate.
It is common in the fence post art to provide the elongate surface of a fence post a T-post for example, with a centralized row of spaced lugs or studs and to also equip the lower end portion with an elevated flat holddown and anchoring plate which, as is generally the case, is substantially trapezoidal in plan or configuration, as herein shown. The object of the present invention is to implement the leading or extreme lower end of the post by adding thereto a novel foot-type earth penetrating and holddown anchor.
The metal post herein shown is conventional in that it is T-shaped in cross-section, but can be L-shaped or even I-shaped or the like. The flanged portion on which the fence wires are fastened is provided, as usual, with a centralized row of vertically spaced outstanding wire positioning lugs or studs. The aforementioned anchoring plate is fiat-faced and generally trapezoidal in elevation. The central portion is slotted and securely fixed and the outstanding end portions provide triangulate wings, some-- times referred to in the art as penetrating and holddown flukes.
Briefly, the herein disclosed concept has to do with a substantially U-shaped fence post anchor which serves as a turn-resisting and stablizing foot. The web or plate portion has aligned slots and two of the post studs are passed therethrough and are hammered and peened in place. The porjecting end portions of the plate portion are provided with upper and lower pairs of flanges which serve as fluke-type earth cleaving and holddown wings. The wings of the upper pair are spaced above the wings of the lower pair in a manner to provide earth compacting, and consolidating and tamping gaps. Then, too, the upper wings are offset beyond the lower wings and converge upwardly and toe-in inwardly while the lower wings converge downwardly and also toe-in inwardly. This thus improved p lC post helps to tamp the soil within the confines of the upper and lower wings so firmly that the post is securely held in place.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIG. 1 is a view in elevation showing the improved post and both anchors embedded in the earth and illustrating fence wires attached to the upstanding portion of the post.
FIG. 2 is a fragmentary perspective view of the lower end portion of the post omitting the regular plate anchor and showing, on a slightly enlarged scale, the improved U-shaped foot-forming anchor.
FIG. 3 is an enlarged detail sectional view taken on the plane of the vertical section line 33 of FIG. 2 looking in the direction of the indicating arrows.
FIG. 4 is an enlarged horizontal section taken on the plane of the section line 4-4 of FIG. 2.
And FIG. 5 is a fragmentary elevational view showing the open or channel side of the improved'anchor.
By Way of introduction to the detailed description, it is to be pointed out that while the example fence post herein shown is T-shaped in cross-section it is within the purview of the invention to employ posts having, as is common in the art, cross-sectional shapes such as L shaped, I-shaped and the like (not shown). However, and for purposes of the present disclosure a T-shaped post is shown. The main flange or head is denoted by the numeral 8 and the centralized reinforcing rib at 10. The over-all post is denoted by the numeral 12. The post, as is customary, is centrally provided along the front surface with vertically or longitudinally spaced lugs 14 commonly referred to in the art as studs. The upper end of the post is denoted at 16, the lower end portion at 1'8 and the extreme lower end or terminal portion at 20. The portion 18 is provided above the-terminal end 20 with a plate anchor 22 which is in common use on metal and steel fence posts. This plate anchor is substantially trapezoidal in elevation as brought out in FIG. 1, the upper straight edge being denoted at 24, the lower narrower straight edge at 26, and the inwardly and downwardly sloping marginal edges at 28. The centrally apertured portion of the plate is superimposed on and secured in place with cooperating peened studs 30 extending through adapter slots 32 provided therefor as shown in FIG. 1. The anchor equipped post thus far described is conventional in the fence post art.
The lower end portion below the level of the anchor plate 22 is provided with an added as well as uniquely constructed and performing earth cleaving and holddown anchor which is denoted by the numeral 34.
This anchor 34 is substantially Ushaped but may also be interpreted as channel-shaped in cross-section. The web or plate portion 36 is substantially rectangular in plan and has its central portion provided, as shown in FIG. 4, with upper and lower slots 38. These slots are such that they permit the passage therethrough of registering studs one of which is designated in FIG. 4 by the numeral 40. These studs are such that they project through and beyond the slots and the projecting ends are hammered or otherwise flattened and peened in place as at 42. The plate portion 36 is of a width appreciably greater than the cross-sectional width of the flange 8. As
will be evident particularly from FIG. 5, the upper half portion of the plate is wider than the lower half portion. The vertical marginal edges of this upper half portion are provided with laterally projecting opposed flanges which are designated as upper flanges 44. Corresponding vertical marginal edges of the lower half portion are provided with similar laterally projecting flanges which are differentiated by the numeral 46. It follows that the distance between the paired upper flanges 44 is greater than the distance between the companion pair of lower flanges 46. It will also be noted that with this dimensional difference the flanges 44 are offset outwardly from the flanges 46. Accordingly the lower edges 48 are spaced above the upper edges 50 in a manner to provide clearance gaps 52 to the left and right in the manner illustrated. It will be further noted that the flanges 44 converge upwardly and slope or toe-in toward the marginal edges of the post flange 8. On the other hand the paired lower flanges 46 slope downwardly in inwardly and converge or toe-in toward the lower end portion of the post. It is also to be noted that the bottom edge of the plate 36 as denoted at 54 projects beyond the terminal end 20 as brought out advantageously in FIGS. 3 and '5 in particular. With this construction it is also obvious that the bottom edges of the paired flanges 46 also project beyond the terminal 20 so that the several coacting edges can be piloted and more easily driven into the earth or ground. As the post is driven into the ground the dirt passing between the respective upper and lower flanges by way of the gaps 52 is compacted and consolidated causing the post to be firmly held in the ground.
Experience has shown that a post whose lower end portion 18 is provided with upper and lower anchors 22 and 34 well serves the purposes for which it is intended. It functions to hold regular steel posts down so that the fence will not pull the post where it crosses a ditch or a low place in the terrain.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
