ANCHORING STAKE Filed Aug. 14, 1953 IN VEN TOR.

Eli/{E57 D- 1'4 A/IVE 7-7- United States Patent ANCHORING STAKE Ernest D. Iannetti, Osterburg, Pa. Application August 14, 1953, Serial No. 374,307 1 Claim. (Cl. 119-121) This invention relates to an anchoring stake, and more particularly, the invention has reference to a device of this type which is adapted for many uses. For example, the stake constituting the invention is usable as a means to which a dogs chain or tie rope can be attached, for confining the animal to a particular area. Then again, the device is usable for any of various other purposes to which a stake or hold-down means is suited, as for example, a ground anchor for guy ropes, tent ropes, etc.

One important object of the invention is to provide a generally improved device of the character referred to which will be so designed as to be especially well adapted as a means to which one end of a dogs chain or exercise rope can be secured. Heretofore, anchoring devices used for this purpose have, in many instances, not proved entirely satisfactory, due to the fact that they tend toward winding of the chain or rope thereabout. In other instances, the devices are overly complicated, and in still other instances, they are not so designed as to permit partial disassembly there of when not in use. Partial disassembly of a device of this type is desirable, it may be noted, under circumstances in Which it may be desired to cut the surrounding lawn. It is of course desirable, on such occasions, that the safety stake not project above the ground surface, thus to permit the lawn mower to be moved directly thereover.

Still another object is to which wil other end, which pin is adapted for connection of a flexible element thereto, the pin being shiftable out of a vertical position in any direction, thereby to prevent entanglement of the flexible element With the body of the stake.

A further object of importance is to provide a construction wherein the upper end of the stake will be fitted with an aperture cap, said cap being circumposed about the pin and having a conically sloped surface adapted to form an abutment for the pin, thereby to restrict the pin in its movement in a direction away from a vertical position, after the pin has shifted to a predetermined angle from the vertical.

A further object of importance is to provide a stake as described which will be simply designed, inexpensive of manufacture, and yet rugged and trouble free in operation.

Other objects and advantages will appear from the following description, the claim appended thereto, and from the annexed drawing, in which like reference characters designate like parts throughout the several views, and wherein:

Figure 1 is a perspective view of a stake formed in accordance with the present invention, as it appears when in use as an anchoring device for a dogs exercising chain;

Figure 2 is an enlarged view partly in side elevation and partly in longitudinal section of the stake per se, portions being broken away; and

Figure 3 is a fragmentary, exploded perspective view.

The reference numeral has been applied generally in the drawing to designate the stake constituting the present invention. The stake is provided, as particularly well shown in Figure 2, with an elongated, generally vertically disposed, cylindrical stake body 12, said stake body being formed at its lower end with a conically tipped ground point 14 adapted to facilitate penetration of the ground by the device. per end, the stake body 12 is formed with a reduced, threaded, axial extension 16, and in the end surface of said extension there is formed a centrally disposed,

At its upsurface of the end wall, 11'] this connection, is conically sloped as at 34, oppositely to the sloping surface 32 and faces inwardly of the cap 28 to cooperate with the adjacent socket gaged in the socket 18, the edge or opening 30 1n the socket engaged position of the all being spaced above and out can swing freely in any direction, when pull is exerted thereagainst from said direction. For example, in Figure 1 there is shown the device can be extended into the ground surface to an extent sufiicient to dispose the the ground surface, and by reason of this arrangement,

could be removed, for insertion of the pin 24, ball 20, and 2cap 28 In their assigned positions shown in Figure It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles of operation and the means presently devised to carry out said principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claim.

What is claimed is:

An anchoring stake comprising: a generally vertical, ground-penetrating stake body having a reduced, threaded, axial extension at its upper end formed with a hemispherical ball socket; a ball having a diameter corresponding to that of and universally movable in said socket; a pin secured at one end to said ball and projecting upwardly beyond said end of the body, said pin being substantially smaller in diameter than said ball diameter and being adapted at its other end for connection of a flexible element thereto; and a cap of inverted cup shape threaded onto said axial extension and having an end wall formed with an aperture smaller in diameter than the ball, said aperture being substantially greater in diameter than the pin for extension of the pin therethrough and for universal movement of the pin with the ball, said end wall of the cap being adapted to engage the ball to hold the same within said socket, said end wall of the cap having a conically sloped first surface surrounding the aperture, said surface facing outwardly of the cap and being adapted to form an abutment limiting universal movement of the pin in a direction away from a vertical position, and a second surface conically sloped oppositely to the first surface and facing inwardly of the cap to cooperate with the adjacent socket-formed end surface of the extension in defining therebetween a frustro-conical cavity confining substantially the entire portion of the ball not engaged in the socket, the edge of said aperture, in the socket-engaged position of the ball, being spaced above and out of contact with the surface of the ball to permit limited up-and-down movement of the ball between said socket and said edge.
