monnnon. rosrs.

To all it may concern} a citizen of the United Bloomington, Monroe county, and State of Indiana, have invented anddiscovered certain new and useful Improvements in Molds States, residing at fication. g Y

y said invention consists in 'a' meth0d' apparatus forforming posts composed whereby such a post may be formed so that all of the component parts will be securely and permanently united inone homogenous structure and a post provided the main part of which is composed of comparatively inexpensive material united and combined in a solid form and veneered with the minimum amount of more expensive material required to givethe, post a finished appearance, thus post of great strength and lmpervious and finished surface, all as will hereinafter more fully described and Referring accompanying drawings acentral section through the mold with the portion of Fig. 1 on an endotted lines, Fig.6, a crosssection through the same on dotted line 66, Fig.7, a per a'detail view of the lower portion ofFi g. 2

In said drawings the portions marl zed A represent the mold, B B the sections composing the bulk-head and C the wire basket he mold body A is preferably of sheet is formedopen on one side with vertical along the. respective v.edges as shown, and on the inside of itslower' with the opening in body A, to strengthen Specification of Letters Patent. A pneauen filed m 17, 1912. Serial lie-698,057.

' and turn cam, edges of said levers bear againstthe 1' outer face and nuts- 15 5 are used to adjust their lengths so that when "which made a part hereof and on which similar reference characters indicate simie vals along both their edges,

heads 19 of which the upperedge of which a concave plate 11 is adapted to rest when the mold is in a closed. position. 'A removable section A is adaptedto fit withinthe longitudinal openmg in body A and is formed with out-turned flanges a and a? Said section is best shown in panel on. one supports to rest upon. A series of bolts 12 extend through perforations in said flanges a, a, a and'a across section A, transverse heads I3 cylindrical in form .ee .which cam levers 14 are mounted. Said lepreferably. formed flat, as Fig. 3, so as to form-a flat fvers '14 have cam shaped heads with center slots through which the bolts 12 extend with the heads 13 resting in notches in the outer'edge of said levers. 'Said levers are 1 formed of sheet shown, and the two sides are bent so that they will bear against the sides ofbolt 12 on the head 13 as a fulcrum. The

of an outside flange a (or. a on the opposite ends of bolts 12 having.

metal, bent to the form t nt d. Nov! 19, 91 .5

respectively which fit between the adjacent faces of flanges a and a side of the post for the wire saidlevers are in the position shown in Figs.

- 1;, and 5 the flanges will be clamped together,

the body A charged.

The bulk-head is composed of several sec tions B and B the sections B over-lapping on the outside at both edges the adjacent edges of sections 13. Said sections B have a series of clips 16 riveted thereto at interforming ways or pockets into which the edges of the adjacent sections B may slide. Near the lower ends of sections B are mounted rivets, the

project beyond the surface and form buttons over which notches 17 in the'lower end ofsections B may engage. When the parts are assembled, as shown in Figs. 2 and 3, the edges of the sections B are engaged by the clips 16 on the sections B and the notches 17 engage under the rivet heads orbuttons 16; andv a band 18 surposition the* platelljl will be supported on the 7 rounds the top, holding said several sections together and forming apractically imperforate' bulk-head, which surrounds and by the means above described, held upon the ,every direction. 3 V

In use the shell A is closed by securing basket C. Said formed of sub outside of the woven Wire w1rebasket or form C 1s 'stantially the form desired for the post including the oval top thereof which is complete and in 'piece with the several sides 01 the basket each posite sides thereof, thus tying all-sides of said form together in a uniform inanner and al structure, all parts of which as an inte V are adapted to resist str in on the post from flat section A in position by means of the clamping camlevers 14:,- as shown in Figs.

1,3 and 5, and the concave plate 11 is dropped to position therein, closing the lower end of sald mold. A small quantity of rich concrete is then dropped into the bottom of the mold and spread over the plate 11 sealing the joints between the edge of said plate and the shell A and'forming the veneer finish, for the top of-the post.

Rods 20 having hook shaped ends are hung over the top of. the shell A and extend down to near the bottom of the mold lying againstthe sides of said shell and are spaced at 1nexcept such portions each other,

tervals around the circumference thereof. The basket G, covered by the plates B and B secured thereto as above described and forming a bulk-head verted and dropped into the mold, the rods 20 serving to guide and center it therein so. that a narrow uniform space will surround this bulk-head structure onall sides. The wet concrete of a' rich character is poured in the space between the bulk-head thus formed by the basket G and plates B and B? and the mold. Acheap coarse concrete composed largely of crushed stone, gravel, cinders, or like material, is pouredinto the interior of basket C until it is filled. Both the rich concrete on the outside of the bulkhead and the low grade concrete on the in'--'.

terior ofethe bulk-head are mixed wet and are of a character adapted to pass through the fine rich mixture, which has been re-- tained outside said basket by the bulk-head, now settles against the'surface of said structurecom osed of the coarse mixture and wire, an adhering thereto forms a thin veneer, com letely and one that a will strand of wire running over the top and in a spiral direction down opwire support, such as structure, is then in- 'after the r'naterialcomprising the The rods 20 are then withi then withdrawn, and are withdrawn allow -j' grades of concrete to unite with;

move the form or basket C sponding flanges along. its edges,

coveringthe same and giving the post a finished smooth exterior resist moisture and all weatherconditions. Afterv the material has remained in the mold until the whole structure hashardened, or cured, the mold is in verted and the cam levers 1.4 are turned from the position shown in Figs. 1 and 5 to that shown-in Fig.'-7, allowing the metal shell A to expand, opening the joints bebe easily dischar ed.

, tween the flanges and permitting thepo'st to 7 It will be notedespecially by referenceto v Fig. 3, that one side of the post is formed flat for a portion of its circumference, This" flat portionis preferablyfform'ed by the res movable section A of the shell and extends throughout the height of the post and is intended as a bearing I forms the sub ect matter of my applicationfiled herewith, and

face for the plate of a 5 thus serves to holdfsaid plate from turning around said post. p v a Havingthusfully described my. sardinvention,:whatI,cla-im as new and desire to secure by Letters Patent, is: I
