WILLTAM TSHICKS, 0F BLOOMINGTdNfINDIANA. I t I To all who'mdz maybfonc ebm;

Be it 'knbwnfthat I, WiL'LiAMf T. HICKS, a citizen "of the United 'st'zitesgfre sidiiig at Bloomii' gton, Monroe" county, and 'Stiite' of Indiana; have invented zin'd discb'ver'ed certa'in new a d useful Inipfr'bveiheiltsin'Mblds 'for Positsfof Which" the following is 1315601 and ofa smooth and zitt hc'tive fiiiih,While,

for the purposes of ebdrioiiiyfmainifa turethe interior 'porm ns-ef the 'postn iiy conveniently at 'ceihpafatively gsn 'iii pen'se, all aswi ll behereinz'iftef fii'bre' fu 1y described and claii'r'ied'.

I Referring tq' the a companying chziwifigs,

' end of saidgmding m mber,-

- Figi 5,";i perspeeti ve View efdfth' "her be composed of cogxiiser ni'zite'nai withdiit Fig. 56, a top View, aiid ssis 'ction finft he' tiiitttffiiii' r it (:10. The edges ofoach alternate section are turned outwardly slightly to form spacing ridges .20 between the outer shell l0 and the outer surface of said grading member.

Other spacing members 18 may be interposed such as small,.zlongitudinalribs crimped in the perforated plates, or a rod fastened vertically thereto. Such rods or ribs 18, and the turned out edges 20, serve to support and steady the: gradingmembers and space the same at proper distance from inner Wall of the outer shell 10. The upper end of cylinder let of said grading member extends for a distance to Within the sections l6and serves to prevent them from collapsing. At ntervals around the cylinder '14, 011 its inner face, are mounted sockets 21 for receivingand supporting re,-

inforcing rods 22. Said rods are supported by small hooks, or otherappropriate means atitheir upper ends, so as to prevent the r lower ends from approaching too close to,

the surface. ofthe .disk l3 and projecting through the cement forming the upper end of the post. The sockets 21 are of suificient size so that said hook endsmay passthrough when the" grading member is removed,

leavingsaid reinforcing rods embedded in the concrete. Other reinforcing members, such as the spirally Wound basket of my Pa ent No. 1,015,026, maybe adapted for use with thismold, if preferred. v Each of the sections 16, as clearly shown in the drawings, is formed with numerous perforations,- said perforations being of a size to permit the fine semiliquid concrete to. run through them. -The spacebetvveen the outer'wall l0, and the grader Wall is so T narrow or" thin that no coarse material can get through or occupy it, but such stuff Will strikethe outer Wallbefore, clearing the perforations, and Will be forced back toward the interior during the process of ivithdraivingthe perforated plates and completely covered by the fine concrete. 1 'lnoperatiomthe parts are assembled as shown in Fig. 1, the reinforcing rods 22 being inplace and supported above; the .disk

. fora short distance, as shown. A small quantity of'fine concrete is first deposited on the upper surface of disk 13 to form the top surface of the post. The concrete mixture is then; poured intothe top through the interior of cylinder 14-. Sufi'icient of-the me, or semi-liquid cement, Will percolate through the perforationsin the members 16, into the space between said .members and the outerTshell 10,.to .fill said spacc. After the gradingmemberfhas been "filled to near the top,- the cylinder member 14 is With drawn. byhookingsuitabler -lifting tackle (not. shown) ,into' appropriate ears. or holes 23 formed infitsv sides. :Therods 22 are turned sothat. theirihooks Willpassthrough assa e:eae l r said em.-

isaeeos nlain embedded in the concrete. The 1ncn1- hers-l6 are then Withdrawn by hooking suitable lifting tackle into appropriate ears, or eyes, 24: in the upper ends thereof. The concrete then settles in the mold, the fine concrete being packed "against the interior of the outer shell 10. The concrete is al lowed to dry or cure. After it is cured or set, the outer shell may be removed by loosening the clamping bolts 12.

being manufactured. Posts for-some. pur 1 posesmay' be made of a larger proportion of the coarse inexpensive material than others, and ithout in any manner impairingthee'liiciencyof the product. The operation of the mold requires no skill for ex perienc'e, it being simplein structure and easy to; assemble fiIlCldlSIllfLIlt-lfi as will be readily seen. i. e

,l/VhileI have described this mold as for the manufacture of concrete posts, it Will-be understood,, of- COUPSSythM] it may beadapted for other usesfor which it may be found appropriate, all; such uses and modifications being Within the scope ofmyinventionand intended to be. included Within the meaning of the terms used herein. Itgivill-be understood, of course, that arions modifications ill the details of construction may be made Withoutdeparting from the spiritand scope ofmy invention as de x fined in the following claims.

Having thus fully described my saidinvention,:.vvhatI claim as new and desire to secure by Letters Patent, is:

r 1. A mold for concrete posts comprising an outer imperforate shell. and an inner shell having Walls with openings therein andcomposed oflongitudinal sections and an upper end section through which the concrete is admitted, substantially as set -2. A mold fori forming concrete posts comprising an outer imperfora'te shell, and inner perforated shell, made up of sections and spaced a distance therefroimrand an I end section for said inner, shell adapted to receive a concretemixture andformed'to be removed after saideoncratemixture is depositedtherein, substantially as set forth. ;3 ..A mold for forming concrete posts comprising an outershell having. an imperforate Wall and a closed lower end, an inner shell with perforated Walls and open Eat both ends, and an upper end section formed for connection with said inner shell and adapted to receive the concrete mixture, said interior shell being fo med in sections and to be removed after said concrete miX- ture has been deposited therein, substantially as set forth.

: 4. A mold for forming concrete posts, comprising an outer shell, a grading member within said outer shell formed of perforated sections, a cylindrical upper end section detachably mounted on said perforateol sections, and means for spacing said grading menrber from said outer shell, said grading member being formed to be removed after the concrete has been deposited therein, substantially as set forth.

5. A mold for forming concrete posts comprising an outer shell, a perforated grading member mounted within and spaced from said outer shell, said grading member being formed in sections'and attached to a hollow cylindrical upper end and having therein means vfor temporarily suspending and supporting reinforcing members, substantially as set forth.

comprising an outer shell, and a grading I member formed of longitudinal sections joined at their edges and adapted as a whole to cooperate with and for use within said outer shell having perforated walls spaced adistance from said outer shell and formed to be removed after the concrete mixture is deposited therein, substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Bloomington, Indiana, this 11th day of March, A. D. nineteen hundred and fifteen.
