APPLICATION FILED SEPT-3. 1914.
SCHUYLER RENWICK SCHAFF, 0F LOUISVILLE, KENTUCKY.
To all whom it may concern Be it known that 1, SGHUYLER R. SoHArF, a citizen of the United States, and resident of Louisville, in the county of Jefi'erson' and State of Kentucky, have invented certain new and useful Improvements in Guy- Anchors, of which the following is a specification.
This invention relates to certain improvements in land anchors, and more particularly to'that type adapted for use in the anchoring of guy wires, for telephone poles, telegraph poles and other structures.
My improved construction includes a body portion and one or more anchor blades carried thereby and movable in respect thereto, so as to lie closely adjacent to the body portion when the anchor is inserted in the ground and spread out into the surrounding ground and effectively prevent the removal of the anchor upon a movement of the latter in the reverse direction.
- The main feature of my invention invovles the construction of these anchor blades and the means for'attaching themto the body portion. The anchor blades are formed of, elastic resilient material and normally extend upwardly and outwardly from the body portion. The elasticity is such that when the anchor is forced into the ground, the blades may bend and assume positions closely adjacent to the body, while the resiliency is such that as the body tends to move in the opposite direction, the blades will be forced outwardly into the ground and present greatly increased gripping surfaces.
By means of my invention, I greatly reduce the cost of manufacture of the anchor, as I avoid the necessity of machining any of the parts and avoid the use of all pivot pins or other hinge connections.
ll secure a more even. distribution of strain on the several anchor blades, as each blade may bond or give to a different extent, and assume its proper proportion of the load. This is a very marked advantage over that type of construction in which the blades are pivoted and swing into engagement with stops, as in the last mentioned construction; the on gagement of one anchor blade with a stone or other solid and relatively immovable object will cause that blade to take all of-the load, while the others are resting in loose earth.
Specification of Iietters Patent.
In the accompanying drawings, I have Patented Sept. 14, was.
Application filed September 3, 1914. Serial No. 860,010.
illustrated one embodiment of my invention, but I wish it particularly understood that. various changes may be made within the spirit of my invention and without departing from the scope of the claims. Therefore, I desire the form shown in the drawings to be considered in an illustrative rather than in a limiting sense.
In these drawings, 1n which similar reference characters lndlcate corresponding parts in the several views; Figure 1 is a side assume when an upward strain is applied to the anchor; and Fig. 3 is a perspective view 'of'the anchor as it appears removed from the ground.
In the specific form illustrated, the anchor includes a body portion 10, having a sharp point or head 11 at its lower end, and an eye 12 at its upper end for the attachment of the guy Wire or other member to be held. Along the length thereof, and particularly adjacent to the lower end I provide a plurality of anchor blades, which, as previously stated, involve the main feature of my invention. Each blade extends upwardly and outwardly from the body portion 10, and normally assumes a position substantially as shown in Fig. 3. The lower end of the blade is rigidly secured to the side of the body portion, and the blade has such resiliency that the upper or free end may move toward and from the adjacent face of the body portion preferably nearly if not entirely into engagement with the body,- by reason of the pressure of the earth against the outer surface of the blade during-the driving of the anchor into place, and out into the earth when a pulling strain is applied to theupper end of the anchor. in its preferred embodiment, each blade includes a strip or plate 13 of spring metal, and a second and shorter strip or plate 14 of the same material. The shorter strip or plate engages with the outer lower surface of the plate 13 so as to act as a reinforcement for the latter. The two plates, at their lower ends, are rigidly secured to the body in any suitable manner, as for instance, by rivets 15. By
or plates, and with the inner strip or plate longer, the upper end will have the greater resiliency and the outer plate will act as a reinforcement for, the base. Instead of forming the blade of two separate plates, it is, of course, evident that a similar result might be secured by using a single strip of varying thickness, the greater thickness being at the base. In some'.construct1ons, 1t may not be necessary to provide any reinforcement or increased thickness at the base. In the specific construction I have shown, the body portion is squarein cross-section, with each of the four sides provided with a separate anchor blade and with blades on 1 opposite sides at substantially tance from the end of the anchor. It 1s, of,
the same discourse, evident that the body might be of any other desired cross-sectional form, and that a greater or lesser number of blades could be employed.
In using my improved anchor, the pointed end may be forced directly into the ground to the desired extent, and without the preliminary boring or digging of a hole, al-
- though of course, if the ground be particularly hard or stony, a hole might be dug into which the anchor could be placed. The anchor is particularly useful where the earth is suiiiciently soft to permit the anchor to be driven into place, and the elasticity and re siliency of the blades is such as to facilitate the driving of the anchor into place, and at the same time to prevent its withdrawal upon the application of an upward or pulling strain Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is
1. A guyanchor including a body portion and an anchor blade, said anchor blade havng its lower end rigidly secured to the side of said body portion and having its opposite .end extending upwardly and outwardly at.
an angle to said body portion, said anchor blade being formed of resilient material whereby the upper or free end may move toward the body portion as the anchor is forced into the ground and may swing outwardly into the ground as the anchor is moved in the opposite direction.
2. A guy anchor including a body portion and an anchor blade, said blade including a resilient strip or plate having its lower end rigidly secured to said body portion and having its upper end normally spaced from and movable toward and from said body portion, and a reinforcing strip secured rigidly to said body portion and engaging with the outer surface of said strip or plate along the lower portion of the latter.
3. A guy anchor including a body portion and a plurality of anchor blades each formed of resilient material and having its I lower end rigidly secured to said body portion and its upper end spaced from and movable toward and from said body portion, said anchor blades being arranged in pairs on diametrically opposed sides of said body portion, and successive pairs being secured at spaced points along the length of the body portion and upon different sides thereof.
Signed at Louisville, in the county of'Jefferson and State of Kentucky, this 28th day of August A. D. 1914.
