MILLARD r. HoYLn, or nannies, TEXAS.

rLAszrc Bnsn non roms.

To all whom t may concern Be it known that I, MILLARD F. Hom, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful the ground, the pole being suitably fastened on the base which latteris embedded in the ground. By this it is sought to lengthen the life of the average pole and prevent it from rotting and breaking off at the ground line. A further feature is yto enable the use of a pole of less length than is ordinarily used, but to support the top of the pole at the saine elevation as that ordinarily employed.

In carrying out the invention a core is placed in a suitable mold and both are placed in the hole. Concrete or other plastic material is poured intoA the mold whereby a base is formed with the coreA embedded therein7 the top of the base extending above the ground. AFastening devices rise from the base. The pole is set on the' base between the fastening devices and fas-l tened. rlhe base is cast with an ample footing and is reinforced by the core which is preferably of the skeleton type. The mold is removed after the base has hardened so that dirt may be'paclred around the base before the pole is set. Other novel features will be hereinafter pointed out.

The invention will be more readily understood from a reading 'of the following specificationV and by reference to the accompanying drawings, in which an example of the invention is shown. and wherein:

VFigure 1 is a side elevation of themold and core in the polehole,

Fig. 2 is a similar view at right angles to Fig. 1,

Fig. 8 is a detail showing the base in sec@ tionand the pole in elevation,

Fig. 9 is'an under side view of thel pole, Fig. 10 is a side elevation of the same, and Fig. 11 is an under side view of the foot of the 'core.- l Y l In the drawings the numeral 10 designates opposed side plates of a mold box. End

' plates 11 fit between the side plates. The

plates converge downwardly so that the mold box is small at its lower end. Keeper strips 12 fastened on top of the end plates overhang the upperends of the vside plates and are apertured to receive fasteningpins 13 which are seated in the upper ends of the side plates. As an additional fastening means each endplate carries a centrally pivoted latch 14C` having opposed notchesfl vat its outer ends'adapted tohengage headed studs 1G projecting from the edgesof the side plates. Each sideplate carries a strap 17 at its lower end having inwardly .directed hoops 1 8 receiving tonguesv 19 formed by f slotting the lower edges of the end plates. By removingv the pins 13 and unfasten'ing the latches 14 the en'd platesmay be removed.

A core memberis employedand comprises a foot .portion 20, upright members 21 and a central member 22 all preferably formed from a single piece of wire bent as shown in the drawings. In preparingthe base .a hole is dug in the ground andthe core-.placed in the hole so that it rests on the bottom. 2 The foot 20 comprises four `rings or branches Fas will be clearly seen fromv Fig. 11,y and this foot covers a greater area vthan the lower end ofthe mold. The members 21 and 22 are contracted just above the foot 20.

A threaded bar 23 extends across the central portion of the mold and has itsends embedded in end plates 11, another threaded y bar 24 at the top of the mold'also :has its end embedded in the end plates. 21 are looped over the bars 23 and`24 and The members the memberv'22 is arched overthe bar 23.l

Fastening bars 25 Vare apertured to vfit on'the between the end plates and nuts 26 which latter limit the inward displacement of said bars 25. .The bars 25 extend from above the. mold and above vthe surface ofthe ground.

ends ofthe bars 23 and 24;, beingconfined A bars 27'l also extend some distance above the mold box. These details are clearly shown in Figs. 6 and 7, and itis to be understood may be changed in shape and arangeinent as the occasion may require.

lith the parts 1n position concrete or other plastic material is poured into the mold box so as to flow down through the same and surround the footing 20. When the mold box. is full cap members 30 are employed to mole the top of the base which latter I have designated by the letter A. It will be seen that the core is entirely embedded in the base and forms a reinforcing; likewise the threaded bars and the upright bars 27 are embedded in the base and also form reinforcing. Y

The bars 25 are not embedded in the base and when the mold box is removed and the dirt tamped around the base space if leftl for removing one of saidv bars 25 as is indicated in Fig. 4. A fulcrum bracket 31 is fastened on the end of the bar 24 from which' -the bar 25 hasbeen removed.- A keeper 32 including a loop .33 is .fastened to the pole near its butt. The fulcrum bracket is received in the loopas is shown in Fig. 4i so that the butt of the pole is supported so asto swing into properposition on top of thebase Vwhen the pole is raised. The butt of' the vpole is provided with scores 34 and a layer of cement B is spread on top of the base so that when the pole is raised into position this soft cement will spread into the scores and whenY set .will hold the pole against displacement. After the pole is raised into position the fulcrum bracket 31 and the keeper 32 .are-removed and the bar 25 replaced. After'which the dirt may be filled in-the holefin the space which has been left for said bar.

f 4The bars 25 and 27 are suitably `bolted to vthepole and the llatter is firmly held in place as is obvious. It will beseen that when it is necessary to replace the pole it will only be necessary to remove the bolts from the bars and one of the bars 25 so that anew pole maybe easily placed in position.r

What I claim is: Y l; In a device'of the character described, a plastic base,V a reinforcing member for the plastic base formed Vof a single section of wire bent lto lform an approximately U- shaped 'central member having a transverse portion, said central member having the lower ends of its sides bent outwardly and at substantially `aright angle for forming outwardly projecting feet, the wire extending upwardly -beyond certain of the feet in the form of upright portions and being bent of a single into loops, a pair of upright fastening bars having their lower ends apertnred-to receive the transverse portion of the centralV member and projecting above the plastic base, a second pair of upright fastening bars embedded in the plastic base and projecting above the same, and a transverse bar connecting the second named pair of fastening bars and passing through said loops. p 2. In a device of the character described, aplastic base, a reinforcing member for the plastic base formed of a single section of wire bent to form an inverted approximately U-shaped central member having an upper transverse-portion and depending sides, the lower ends of said sides being bent laterally and outwardly and also at substantially a right angle forV forming radially.' projecting feet, the material ofv the feet being crossed, the wire extending upwardly from certain of the feet in the form of upright portions bent downwardly upon themselves into long loops, the upper transverse portion of the central member being arranged beneath the topof the base for a substantial distance andV embedded therein, a pair of upright fastening bars having their lower ends apertured for receiving the upper transverse portion and embedded in the base and projecting abovel the same, a transverse bar embedded in the .npper' portion of the base andconnected with the upright fastening bars, a second pair of npright fastening bars arranged at approximately a right angle to the first named upright bars, and having their lower portions embedded in the base, and projecting above thesame, a transverse bar connecting the lower ends of the second named upright bars and arranged within the approximately U-shaped member, and a transverse bar embedded in the upper portion of the base and connecting the second named upright bars. the two last named transverse bars extend-I ing through and within said long loops.
