1. w. BENNETT. REINFVORCING OF CONCRETE `PSTS AND THE LIKE. APPLICATION FILED MAR.18,1918. gmgl, Panama Mu1.23,1920.
JACKSON tlf. BENNETT,
F CARTHAGE, MISSOURI.
Application filed March E, 192,53.
To all fio/1,0m 'it may Cannara.'
tie it known that i, Jaonson W. Biiiiinn'r'r. a ritiaen of the United States oi America, and a reeidcnt oit Carthage, in the county ot i f and State oi? Missouri, have invented certain nen" and ueetul improvements in fintoreing ot lConcrete Posts and the like. vdiieh the following is a specification.
rilhe primary object oi this invention is to provide an improvement in the construction oi' reinforced concrete posts.
Another object ot this invention ie to provide an improvement in the manner oi? rein- Vtoreing a concrete post, in which the reine ioroing members Will be under oompres-` sional strains, thereby binding and gripping the concrete body ot a post, the purpose ot the reinforcing members not only being to aeeist in stiii'ening the concrete body, but more ior the purpose ot drawing and holding the concrete body together.
@ther and further objects will appear in the specification and be specifically pointed ontl in the appended claim, reference being had to the accompanying drawings eieniu plitying the invention. and in which,
Figure l is a trent elevation ot this iniproved post showing the fence securing strip secured thereto.
Fig. 2 is a longitudinal section taken through this improved concrete post, showing said post in the mold.
lig. 3 is a longitndinai Section taken api proniinately on the'line lil-lll of Fig.
'Fig fi is a fragmentary section taken on the line lV-IV of Fig. 3.
l? 5 ie a transverse section taken on the line "V-V of 2.
Referring to the drawings, this improved post comprises a reintorced body of concrete l or other soli hardening material, and embedded in said body of concrete are a pair ot compressional members 2, and as shown in 2 and 3 ot the drawings which pertain to the molding of the post, said meinbers a are secured to the metallic rods 3 and t and to the tightening vvire 5. A s ehovvn these rods 3 and i have their ends projecting from the sides of the post so as to torni projections which tend to hold the post in the ground.
its shown in Figs. 2 and 3 during the construction or thieimproved post, the rods 3 and ll are first mounted in horizontally arranged positions, their ends engaging their specication of Letters Patent.

respective notches 6 which arec'ormed in the side walls i" of the mold 8.
These coinpressional members 2 are consti-acted oi' barbed wire or the like, one end ot one oi the mi-inbere being secured to the rod i and then stretched lengthwise in the meid and passed through the loop S) ot the tightening wire 5, then rearwardly and over and around the upper rod 3 and Secured thereto, or can be extended to the lower rod et that it will be engaged against said 4tower rod adjacent the opposite end to which the Wire was originally engaged, said nire then being returned in the mold to the loop 9 oi" the tightening wire 5, then rearwardly again to the top rod and seeured thereto an designated at l0. The tightening Wire entended through the opening il ot the head mold end piece l2 and eeenred to the tightening member 18 which eX tends through the brace portion 141:, the tended end of said tightening member 13 being 4threaded and haring a nut 115 mounted thereon.
`"iihen the compreesional member 2 has been mounted in the mold as just related, the tightening' nut l5 is engaged and manipulated so that the tightening member 13 will be drawnu thereby exerting a -pull on the Wire strands of the members 2 and draiving them to the required tightness. A iibrous Securing Strip 16 triangular in cross section .is laid With one of its faces engaging the bottom l oit' the mold in the approxin Vniatc position as shown in Fig@ :2, there being a pair of holes 18 formed in said strip, eaoh hole being for the reception oit a bolt 19j said bolts having their threaded ones extend above the side walls 7 oi the mold. The end piece 2O is then mounted against the ends of the mold side Walls 7 and the mold is ready ilor the reception ot the body ot plastic material as shown in `lig. 2.
After the plastic material forming the body portion l of the post has set, the tightening member 13 is released and disconnected from the tightening Wire 5 and the head piece l2 is .shifted from the top of the post so that the tightening vvire 5 can be clipped close to the top of the poet at a point as designated at 2l. Nuts 22 are then mounted on the threaded ends of the bolts 19 and the post is ready `for use.
From the aforesaid description, it is to be noted that when the looped Wires comprising the compressional reinforcing members 2 Were tightened prior to the lling in of the plastic material, said members 2 Were then under tension and Were so held during the setting of the plastic material around said members 2, said members on account of their being secured to the rods 3 and 4 and tightening Wire 5 being in the form of loops or bands.
Therefore, after the plastic material has set and the post is made, and the tightening Wire 5 is cut, said members 2 Will tend to release from their prior tensionally held positions, thereby applying compressional strains to the set body of concrete in Which they are embedded, and are therefore binding and compressional members rather than stitfening members.
In the use of this improved post, the securing strip 16 is then in position to receive the fence securing members such as nails, staples and the like.
If desired, the coinpressional reinforcing members 2 can be secured and looped independently from the rods 3 and 4 as against the afore related returning and inteilacing` of the Wire.
If desired, the fibrous securing strip 16 and the extending bolts or rods 19 carried thereby can be secured to the bottom 17 oi the mold, thereby forming a permanent part of the mold, so that after the post has been molded, a triangular recess and bolt holes Will be provided in the mold for the reception of a removable triangular shaped nailing or securing strip.
What l claim is:
A fence post comprising a body formed olf cement and having a pair of transversely arranged rods in its lower end, said rods being spaced apart and having their ends projecting from the post, a Wire vertically arranged in the upper end of the post and having a loop at its lower end, and strands of Wire Within the post and extending under tension 'roin the bars through the loop on the vertical Wire and back to the rods` the parts connected with the rods being spaced apart so that the Wire strand assumes the f shape of a V.
