JOHN S. MULLENIX AND WILLIAM H. DRIVER, OF BRADFORD, OHIO.
SPECIFICATION formingpart of Letters Patent No. 672,625, dated April 23, 1901.
Application led November 16, 1899. Renewed August 22, 1900. Serial No. 27.729. (No model.)
To all whom it may concern:
Be it known that we, JOHN SMULLENIX and WILLIAM H. DRIVER, citizens of the United States, residing at Bradford, in the county of Miami and State of Ohio, have invented new and useful Improvements in Fence-Posts, of which the following is a specification.
Our invention relates to fence-posts and to anchoring devices therefor; and one object of the same is to provide means which will permit a fence-post to be driven squarely in the field-line or fence-line and which will be firmly anchored when down.
Another object is to provide a fence-post having a screw-threaded anchor which revolves during the process of driving, while the fence-post remains stationary.
Still another object is to provide means for readily detaching the post from the anchor for convenience in manufacture and shipping and to permit any kind of post to be used with the anchor.
With these objects in view our invention consists of au anchor for fence-posts having a screw-threaded outer surface which conforms somewhat in contour to the quick pitch of an auger-bit and means for seating a fencepost in the anchor in a manner to permit the post to be driven Without rev0lviug,while the anchor turns as it is being forced into the ground.
We attain these objects by means of the -construction shown in the accompanying drawings, in which-f Figure 1 is a perspective View showing a fence-post made in accordance with our invention. Fig. 2 is a vertical section through the center of the anchor and post driven into the ground. Fig. 3 is a view showing in elevation a fence-post which may be used with our improved anchor, and Fig. 4 is a view showing a certain detail to be hereinafter referred to.
Like numerals of reference designate like parts wherever they occur in the various views of the drawings.
The numeral 1 designates a fence-post of any suitable construction provided at its lower end with a round shank 2. Formed at a suitable point in the shank is a groove 3, extending entirely around said shank.
The anchor e consists of a metal socketpiece having a series of spiral corrugations 5 extending from end to end thereof. This anchor is of gradually-tapering contour and the corrugations form screw-threads of comparatively quiok pitch from the base or top 6 of the cone to the point or apex 7 thereof.
A round socket 8 is formed centrally in the base portion of the anchor to serve as a seat for the shank 2 of the fence-post. To hold the shank in the anchor and to prevent longitudinal movement or withdrawal therefrom, a transverse aperture 9 is formed in the anchor and a pin 10 is driven into the aperture and engages the groove 3 in the shank 2. This permits the anchor to revolve on the shank and at the same time holds the two parts against longitudinal separation when in use. The upper end of shank 2 may be provided with a recess or socket for the reception of the end of a fence-post, and this recess may take the shape of any kind of post desired-round, square, or angular.
We may use a cross-brace 1l, having points or prongs 12, designed to be driven into the ground. An aperture 13 in the center of this cross-brace conforms substantially to the shapelof the shank at a point in line with the ground when the post is driven, and after the anchor has been forced into the ground at the required depth the points 12 are driven into the ground and the shank and post are then laterally braced firmly on the line of the ground at some distance above the anchor.
As shown in the drawings, the fence-post 1 is of sheet metal of semicircular or angular cross-section, and this post is seated in a similarly-shaped slit or socket in the top of the shank 2.
Slots or openings 14 are formed in the post to receive metal keepers 15, Fig. 4, through which the fence-wire 16 passes. The keepers l5 are held in engagement with the post by the sliding rod or bolt 17.
It will be obvious from the foregoing that as the post is driven into the ground the anchor revolves, while the post may be held to the line of the field or fence, and when the crossbrace is forced into the ground a firm structure is erected. It will also be apparent that any form of socket may be formed in the IOO rugated cone-shaped anchor having a socket in its upper end, a transverse aperture inter sectingthe socket, a shank fitted Within the socket, said shank having a circular groove around it, and a pin seated iu the aperture and groove to vhold the anchor and shank against longitudinal separation to permit relative'revolu'tion, substantially as described.
2. In a fencepost, the combination of a spirally-corrugated cone-shaped anchor having a socket therein, a shank revolubly seated in the socket, a crossbrace on the shank above the anchor, and a sheet-metal post secured to the shan k,substantia1ly as described.
In testimony whereof we have hereunto set our hands in presence of two subscribing Witnesses.
