DRIVER FOR ANCHOR-PLATES.

To all whom t may concern: p 1.

Be 1t known that I, WILLIAM L.v HAAG, a citizen of the United States of America, re-

7'siding at'Lansing, in the county of Ingham to firmly engage the earth and prevent its being pulled out by heavy strain put upon the stay.

It is also an object-of the invention to provide suitable means for positioning the anchor which means may be-driven into the ground with thev anchor held thereonland may then be pulled out leaving the anchor embedded in the earth at the desired depth. A further object of the invention is to provide certainV new and useful features in the construction of the anchor and driver, all as hereinafter more fully described.

To these ends the invention consists in the matters hereinafter set forth and more particularly pointed o ut in the appended claims, referencebeing had tothe accompanying drawing in which;

Figure l is a side elevation of a driver with an anchor in section in place thereon illustrating the manner in which they are driven into the ground; Fig. 2 isa similar view with the driver removed; Fig. 3 is a detail illustrating the position of the anchor 'in use; Fig. 4 is an elevation of the driver with the anchor in place thereon; Fig. 5 is a transverse section of Fig. l on the line y-Jy; Fig. 6 is a kperspective view of the anchor detached; Fig. 7 is a perspective view illustrating means for pulling the driver from the ground; and Fig. Seis an enlarged de'- Y tail of the upper end of the driver bar and pinch ring thereon.

In providing anchors for the stay wires of telephones, telegraph poles, buildings and other structures it has been the common practice to dig a hole in the ground, place lthe anchor with the wire or cable attached thereto in the bottom of the hole and then fill up ythe hole, but in so lpositioning the( ground unless a great deal of care is taken VvSpecification of Letters Patent. Patented Apr. 1.3, 1915. l Application flied rune 21,1913. seriaiNa'rf/'Sae f l' "6o anchor 1s liable to be pulled out ,of` the to tamp the ground down in the hole and., y

in many instances it is necessary to weight the` anchor vby placing Vstone or other heavy articles thereon within the hole.

In applicants construction a yplate l of' suitable size/and form is driven into the ground edgewise lbymeans of a suitable driver comprising a bar 2 which is 'suitably formed at its lower end to engage and hold the plate while said plate is being driven into the" ground by means of the driver. Thisplate is preferably substantially rec'- ta'ngular in forni andjis concave at its lower side and convex at its uppery side .with ax center hole 13 through which the stay wire or cable 3 is passed and made fast to the i plate by forming a knot on the end of the wire at the under or concave side `of the` plate. The bar 2 is'forrned with a flattened lower end portion lhaving a pointed end 5 so that it may be driven into the ground easily and the fiat upper side of this lower end Vportion forms av seat for the anchorV plate, said plate resting thereon at two'kdia'l'- metr'ically opposite corners'which corners are preferably cut away to vform a straight edge to engage the seat. At the point where the bar 2 merges into the flattened end portion, said bar is formed with an undercutl groove 6 to receive the ,edge of the plate, said groove formingk a firm seat lfor the plate so that ywhen the bar is driven into the ground with the plate engaged therewith,

said plate will be forced edgewise into the l earth. To hold the plate against vlateral movement uponvits seat on the flat side of the bar, a lug'7 is formed on the bar to en- Y gage a slot 8 in the plat e,',the upper side of the lug being tapered or cut away so that it will readilywithdraw from the slot when the bar or driveris pulled 'out ofthe ground by means of a pinch ring 9 which slides freely upon its upper end and is adapted to tilt thereon and grip the bar when it is actuated by `means of a suitable l pry or lever 10 placed through an Vopening in an ear ll on thev ring.

After the driver with the anchor plate in place thereon has been rdriven into the ground as shown in l, and the driver has been removed as shown in Fig. 2, when a strain is put upon the stay wire 3, the tendency of the anchor plate will be to turn within the ground to a position at right angles to the direction of strain upon the stay wire by reason of the attachment of the wire to the center' of the plate at one side thereof and the concavo-convex form of the plate. The two laterally extending corners of the plate which project at right angles to the line of strain upon the stay wire also tend to cause the plate to turn in the ground and if found desirable the plate may be provided with spring fingers l2 which are secured to the under concave side of the plate and curved outwardly and laterally therefrom at each side of the driver and extend beyond the upper edge of the plate. These spring fingers offer no material resistance to the driving of the plate into the ground as they will straighten out as they come into engagement with the earth, but after the driver has been removed and a strain is put upon the stay wire, these lingers curving voutwardly away from the plate in the direction of the line of pull upon the stay wire, will dig into the earth at 'the upper edge of the plate thus oliering an additional resistance at that edge to the pulling of the plate from the ground. The turning of the plate within the ground is therefore made positive by the use of these fingers.

By driving the anchor plate into the ground edgewise the earth is disturbed but slightly and after the plate has turned within the ground by pulling upon the stay wire it will have a firm hold upon portions of the ground which are in their natural condition. An anchor plate of small dimensions may, therefore, be used and the driving of theV plate into the ground greatly facilitates the anchoring of it. Obviously the anchor plate vmay be made of any desired sizeand form with the spring fingers attached thereto or a plain plate used, as desired. The driver' may also have other forms than that shown and other changes may obviously be made in the construction and arrangement of parts without departing from the spirit of the invention and I therefore do not limit myself to the form or arrangement shown.

Having thus fully described my invention what I claim is :d

l. A driver for an anchor plate, comprising a bar having a flattened lower end portion to accommodate a plate, said flattened lower end portion being cut away to provide opposed seats for the lower end of said plate, said iiattened lower end portion having the upper end thereof undercut to provide a groove to receive theupper end of said plate, and a lug on the fiattened lower end portion of said bar adapted to engage the plate.

2. A driver for an anchor plate, comprising a bar having a flattened lower end portion terminating in a point, said flattened lower end portion adapted to accommodate a plate and provide a seat for the lower end thereof, said bar at a point where it merges into the flattened end portion having an undercut groove to accommodate the upper end of said anchor plate, and a` lug on the flattened lower end portion of said bar adapted to engage in said plate, said lug having the upper end thereof tapered whereby it can be readily withdrawn from the plate.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM L. HAAG.
