To all whom it may concem:
Be it known that 1, MART1N P. SMITH, a citizen of the United States, residing" at city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Guy-Anchors, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to new and useful improvements in anchors for guy wires or cables, the principal object of my invention being to provide a comparatively simple inexpensive device which can be readily positioned in the ground, and which device, when properly set, afi'ords an efiicient permanent anchor cable. I
Further objects of my invention are to provide a ground anchor which is adapted to be inserted in the ground with a turning movement similar in all respects to the in-. sertion of a screw; to provide a device, preferably in the form of a tubular wrench which can be readily applied to the anchor for the purpose of placing the same in the ground, said wrench being readily detachable in order that it may be withdrawn after the anchor has been properly embedded; to provide means for locking the wrench directly to the body of the anchor by a rotary movement of one part relative to the other, which parts when locked efiectually prevent relative longitudinal movement of said anchor and wrench, and further, to provide the anchoring rod with a loop or eye which is a spirally disposed flange or blade 16, the
is adapted to receive the guy wire "or cable, and which eye is readily detachable from the anchor rod in.order that eyes of different size may be used on the rod and in order to facilitate the attachment of the guy wire tothe anchor.
Ground anchors of the character to which my inv'en'tion relates are employed for various purposes, a common use being for the attachment ofguy wires or cables employed in connection with poles carrying overhead wires.
With the foregoing and other objects in, view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described,
for the attached guy wire or tegral.

claimed and illustrated in the accompanying drawings, in -which Figure 1 is a side elevational view of an anchor of my improvedconstruction with the driving tool or wrench in position thereupon with a portion of the latter in section. V
Fig. 2 is a .side elevational view of the anchor as the same appears when embedded in the ground. Fig. 3 is an enlarged sectional view of the upper end of the head or body of the anchor and showing the lower end of the wrench or driving tool in position thereupon. Fig. 4 is a detailvelevational view of end of the anchor rod 12, the same being of any desired length and having, its extreme upper end threaded as designated by 12*. The lower end of the anchor rod is positioned in the mold in which the body 10 is cast prior to the pouring of the metal, and thus said body and rod are practically in- Formed integral with the upper end of the body 10 is an upwardly projecting cylindrical member 13 which incloses the corresponding portion of the rod 12, and formed on said member 13 is athread 14:.
Formed integral with the top of body 10 or on the shoulder between said body and the member 13 is one or more lugs 15. Formed integral with or fixed to the body 10 same acting as a screw when the device is placed in the ground andin order to mini mize the resistance offered by the ground when the device is inserted, the lower front edge 17 of said blade is preferably sharpened or made wedge-shape in cross section.
The driving tool or wrench utilized for placingmy improved anchor in the ground comprises a tubular member 18, the same being preferably square or non-circular in and formed integral with or her is a socket 19, preferably cast, and which is internally threaded so as to engage the t re d 1 M 16 mem e 13, Formed int gral with the lower end of sprocket '19 is one or more lugs-20, the same being oppositely disposed with respect to the .lugs 15, and thus when the wrench is manipulated so as to screw-seat'the socket 19 on the threaded shank 13, the lugs 20 engage against the lugs 15, thereby performing the functions of stops and preventing the socket from being tightened upon said member 13. Positioned on the upper end of member 18- is a sleeve 21 in which is seated a set screw 22, the same serving as means for locking said sleeve to the member 18, and formed integral with or fixed to this sleeve are outwardly projecting members 23, which serve as handles when the wrench. is utilized for inserting the anchor in the ground.
A loop or eye 24 having an internally threaded portion 25 is adapted to be screwseated on the upper end or rod 12, said eye serving as an attaching point for the guy wire or cable.
The operation of inserting the anchor in the ground is as follows: The wrench comprising the tubular member 18 with the sleeve 21 and handles 23 thereon is manipulated so that said tubular member is posi- .tioned over the rod 12 and said wrench is now' rotated so as to engage the threaded socket 19 on the threaded member 13. The interengaging lugs 15 and 20 prevent the screwing of the socket onto the member 13 to such a degree as to cause the parts to lock or bind through frictional engagement. This operation serves to firmly connect the wrench and anchor and the point 11 of the body 10 is now inserted in the ground and the entire device is rotated after the manner of operation of an ordinary earth auger, it being understood that during thisoperation, the operator manually engages the handles 23,
and as a result, the body lO 'on which the blade or flange 16 is formed, is driven into the ground to the desired depth.
To withdraw the wrench, the operator merely rotates said wrench in a direction reverse to that in which the anchor was operated to drive it into the ground, which action disengages the shank 19 from the threaded member 13, and said Wrench is now drawn upwardly until it can be disengaged from rod 12. The eye 24L is now screw-seated on the upper end of the rod and the device is ready for the attachment of the guy wire or cable.
It will be' noted that in my improved construction, the lower end of the wrench is directly connected to the body 10 of the anchor when the latter is inserted in the ground and by virtue of such construction the power necessary 'to drive the device into the ground is'applied directly to the head or body without the use of intermediate connections. Further, the threaded member 13 and the threaded socket 19 provide simple means for directly connecting the wrench to the anchor without extraneous means, and without necessitating the placing of the eye .24 or a nut upon the'threaded upper end of rod 12 when the wrench is positioned thereupon. I
In Fig. 4 I have illustrated a modified construction of the joint or connection between the body of the anchor and the wrench or driving tool, this connection being in theform of a bayonet joint. Where such constructionis used, the member 13 is rovided with one or more outwardly projbcting pins or lugs 26, the same being adapted to enter corresponding angular slots 27 formed in the lower end of the tubular member 18. 1
A device of my improved construction is comparatively simple, com-prises a minimum number of parts, can be cheaply manufactured and when placed in the ground serves as an eifective anchor for guy wire, cables and the like. I
It will be readily understood that minor changes in [the size, form and construction of the various parts of my improved device can be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claim.
The combination with a ground anchor comprising a pointed body, a spiral flange integral therewith, a threaded shank integral with and projecting upwardly from said body,lugs in the top of said shank and an anchor rod rigidly fixed to said body, of an. anchor sinking device comprising a tubular member adapted to inclose the anchor rod the lower end of which. tubular member is. threaded for engagement with the threaded shank on the anchor body, whereby the anchor and sinking device may be locked to each other against relative longitudinal movement and lugs depending from the lower end of the tubular member and adapted to engage the lugs on the up- MARTIN P.
