RICHARD TOENNES, OF BOONVILLE, MISSOURI.

CONCRETE roer.

Appnauon :ned Janumy '2, 1925. serial no. nos.

To (1,77 'io/mm 'i wiog/ esmero.:

lie ii known that I, .RICHARD TonNNns, n citizen of the United States, residing :it Boonville, in the county ofCooper und State of liliusouri, have invented certain new and Inee-ful improvements in Concrete Posts, 0i' which 'the following is a specification.

This invention relates to :improvements in concrete fence-posts and has for its objects to provide e strongnnd durable post lnwing a. ineens for readily attaching the fence-wires thereto and holding them tuut und in spaced relation with eachother wilhout the use of tie-wires for the individuel strands.

These and .other objects hereinafter set forth nre nttineil by the means illnstrnied in the zieeoinpenyine' drawing, in whirh:-

Figure l is e perspective View oi the iniprored post. showing sew-.inl dil'l'ereui trpes of vifireel nttuilched thereto.

Figure-2 is' n cross-seetimml View through the pest. I

Figure 3 is n detail perspertive 'View ol :i portion 'of the wire supporting' helix, :ind

Figure 4 is n cross sectional View of the molding frame showing the post while be ing formed and illustrating the nuinner of embedding the wire supporting' helix.

Sin'iilur reference i'iunieriils in :ill of the vfigurer, oi the drawing designate like parts.

Thinl post is Constructed of concrete und is formed with un upper tapered portion l() oriented to support the fence/wires und :i lower tapered portion '11 adapted to serve es n. heee and be buried in the ground, the,

taper of the upper portion being inward toward the upper eno of the post; from en intermediate lower portion Jeing inward toward its lower end froinie serrie..inter1nedi^.ite point, thus iniikingll this intermediate pointthe largest oross-seetion uren throughout thoiength of' the post und designating the ground line thereof.

'llie' post. is preferulily triangular in erosseeetion throughout its entire length and has ln'ojecting from one of its flut luces u pair of longitudinfii ribs 12 having sharp wire engaging edges formed at the opposite edges of Suid flat face and which prei'i erebly extend the full length of the post as shown in the druwing, 'out it is underetood that these ridge@ muy terminate edincent to the ground line of the poet.

oint fend Athe taper of the- YPartially embedded in the post is zi wire helix 13 the coils of which lie relatively clone, together, my, zipproxiinetely two inches eport, :ind with the unernbedded portion oi? the Coils j nfojeeting heyosid vthe front-ieee Mael 'the post to zi point Sul'isiuntinlly in ulinenufuly with the lone-il udinni edges l5 ol:l the ridges l2 for n purpose hereifm'lfier ileseribed. This helix .i3 preferably extends from the top end 0i the post to n poinl somewhat below the ground-line thereof, :zo that the' lower endof sind helix will extend lievlow the eur'lnee of the groiuid when the posi: is set up in position. Also euibmliiml throughout the. length oi the postv :ne ihe reinforcing` rods 'lo which nre prel'erziizly located ndineent the Coi ..-ers thereof.

A. look-rod li' proriileil for retaining the ferire in position :zuninsl the poel, unid loelr-rod being adopted lo hure its ende turned over to forni hooks ,i8 whiih :ferro io reiziin ily .in engugen'ient with the coils of the. he ix.

A. looe'iiuiliruzl zgroove if? nlso forn'ied in-ihe front-tame o'l' the post for n purpoi.- hereinuier set forth.

lin :resembling the fence, the longitudinal feneewires nre drawn taut neroes the frontfece of the post engaging 'the link f'gitudimii edges i5 and lying between the exposed eoie of the helix, :und owing to the position of the outersides of the coils with reterenre to the Vertical edges l5 of the ridges 12, it is neeessury to Slightly bend the feneowhes inwardly between. seid ridges, ns indicated at 20, to permit the pnssuge of the loelerod i7 between the fence-wires and the inner Side of the uneinoedded portion oi the coils.

The close arrangement of the coils pervmite the use of any kind of fence-wire,

either burned, perfectly smooth, or woven es shown in Figure 1 of the' drawing, end should a barb oi the feneeuvire, or n crossing of the woven wire, be accidentally positioned et or near the loek-red'posilion. seid barb er 'erossin een be beutinto the oroove 19 es shown by dotted. lines in Figure 2. Fin-Lherlnore, the elose arrangement of the coils permits the use of n relatively light-weight look-rod, ne the bearing-points of the coiifi against the lock-rod :1re too close. to permit the loelerods bending' outwardly between the eoils under the tennioo off the ienewwires, se that, et ull tin'ies the look-rod remains straight thereby permitting it: easy withfifi lUG

Y The forni of post described is easy to mold, ,ie-economical in material7 and also` strong and durable. tis cast in a V-shapcd iold ndiiclr lirst filled up to the line a-a Figure then 'the lower rod l5 is laid in .c ,l more concrete is added up to line if), and the upper rods 1G are positioned,

then the mold is filled to its top edges and is@ the ridges formed preferably by trowelling.

itf this time, when the concrete is sott and plastic, the wire-helix is forced into the soft material, and to prevent distortion of the coils of the helixnwhile itY is being forced into position, a har 21, preferably oval in crossseotion, is placed within the whole length of the helix'and tliewl'oreing pressure is applied thereto," thereby forcing all of tlie'coils simultaneously into the concrete f and preventing distortion.V After the helix has been forced into the concrete the desired distance, the rod 2l is gradually worked upwardly from engageinent'n'ith the coils and thus working the concrete over the einbedded portion of the coils, it is then bodily removed from within the helix leaving the groove 19 in the face of the post,

Having thus fully described the invention, what is claimed is l. A concrete post oit triangular crossseetion provided with a front-flat face and having a fence-Wire supporting-ineans projecting centrallyV from its 1'ontllat-facc, projecting ridges having sharp wire engaging edges formed at the longitudinal edges ot said froiit-latfaee ateach side of said supporting means, the extreme outer edges of said ridges and the outer sides ot said fenc'e-Wire-supporting means lying substantially in alincincnt, and a look-rod for engaging between the outer-sides of the fencewire-supporting means and the fence-wires.

2. A concrete post of triangular crosssection having a wire helix partially embedded therein, the outer sides of the coils of said helix being projected centrally from the :tront-fiat-face ot' the post, ridges projecting along both sides of said front-face the extreme outer edges of which lie substantially in alinement with the outer sides of the coils, and a lock-rod for engaging betweenY the outer sides of the coils and the fence-Wires.

In testimony whereof I alix my signature.
