ANCI-IOR.
Application filed December 16, 1927. Serial No. 240,404.
This invent-ion relates to an anchor adapted to be secured in the ground, and especially useful in bracing fence posts, telegraph and telephone poles, and the like.
The general object of the invention is to provide an improved anchor of this kind, which is ordinarily connected to the end of a guy line and driven into the ground and which has flukes so constructed and mounted that they have a tendency to spread whenever a pull is exerted upon the guy line.
A more specific object is to provide an anchor which may be easily driven into the ground and which is specially constructed so as to prevent the driving force from injuring the connection of the flakes therewith or adversely affecting the freedom of their spreading action.
The specific construction of the invention, together with the objects and advantages thereof, will be more particularly explained in connection with the accompanying drawing, in which- Figure 1 is a front elevation of an anchor constructed according to the invention.
Fig. 2 is a side elevation thereof.
Fig. 3 is a section taken on the line 3-3 of Fig. 2, showing the anchor embedded in the ground.
The device which constitutes the subject matter of the invention comprises a shaft 5 which is of sufficient length to permit the anchor to be driven a suitable distance into the ground and to leave the upper end of the shaft at or above the surface. The upper end of the shaft 5 is provided with an eye 6 for the attachment of the guy line and its lower end is provided with an eye 7 through which extends a pin 8.
The anchor includes a pair of flukes 9 and 10 pivotally mounted on the pin 8. One of these l'lukes, as 9, is formed with a pair of downwardly extending legs 11 which straddle the downwardly extending central leg 12 of the other fluke. The flukes 9 and 10 are adapted to lie close together, as shown in Figure 1, when the anchor is driven into the ground. They are comparatively thin, gradually diminishing in thickness toward their lower ends which, when closed, have a continuous arcuate edge 13 so that the anchor may be easily driven into the ground. y
KThe central portion of the fluke 1U in the vicinity nf the pin te cut at lfis to receive the eye 7 and is formed with a concave seat 15 against which the eye rests when the anchor is being driven in. rI'he shaft 5 has a conical enlargement 16 thereon a short distance above the eye 7 and the inner faces of the flukes 9 and 10 are formed with tapered recesses 17 to receive the same. In the present instance the bases of these recesses 17 extend completely through the iiukes. The recesses 17 terminate at their lower ends in shoulders 18 against which the base of the conical enlargement 16 engages when the anchor is driven into the ground.
From Figure 3 it will be seen that the eye 7 is elongated with the pin 8 spaced from either end thereof so that when the anchor is being driven in the force of the blows is delivered entirely upon the shoulders 18 and the seat 15. There is no strain whatever upon the pin 8 and consequently there is no chance of bending the pin or otherwise interfering with the free pivotal movement of the linkes thereon.
After the anchor has been driven into the ground as far as necessary and a guy line attached to the eye 7 any pull on the guy line will first raise the shaft 5 upwardly until the pin 8 is engaged by the lower end of the eye 7. During this movement, the conical enlargement 16 moves upwardly in the tapered recess 17, spreading the upper ends of the flukes as indicated by dotted lines in Figure 3. These upper ends are curved outwardly, as shown at 19, and further upward pull transmitted through the pin 8 will cause the linkes to move upwardly and to spread out like a mushroom, as indicated by the broken lines in Figure 1. The fluke 10 is formed with shoulders 2O engageable with the lower portions of the legs 11 to limit this movement when the anchor attains substantially its maximum spread. In such a position the resistance of the anchor is most effectual.
From the foregoing description it will be seen that an anchor constructed according to the invention may be easily driven into the ground without injuring the same and will offer the greatest possible resistance when a pull is exerted by the guy line through the shaft 5. Although I have shown and described the specific construction of the invention in the form which seems at present to be moet des "ble, it wllhe app Mt skilled 'itil the art that xfer'ona 'm may be made therein without any material departure from the scope of the invention as defined in the claims.
-What I claim is:
