Specification of Letters Patent.

Application r1811 May 14, 1906. Serial it). 316,604.

To all whom it may concern: I

Be it known that I, AVE YN I. Dnxrsa, a

, citizen of the United States, residing at Birmingham', county of Jefferson, and State of Alabama, have invented newand useful 1mrovements 1n Processes of Making Concrete.

uilding-VValls, of which the following is a specification.

My invention relates to im rovements in integrally-formed concrete wa ls; and it pertains more especially to the process herein described of forming the ornamental work which projects past the exterior surface of the main body of the wall-such, for example, as are used in the construction of cor nices-andv to represent the base and cap-- stone of windows, doors, &c.

The construction of my invention is explained by reference to the accompanying drawings, in which- I Figure 1 represents a front view of my im proved-apparatus used in the construction of the wall inconnection with a portion of the wall, and Fig. 2 represents a vertical section drawn on line to :c of 1.

Like parts are identified by the same ref- 7 erence-lettcrs in both views.

A represents the body of the wall'in the process of construction, and B one of the ornamental pieces allixed to the exterior surface of'the wall.

The apparatus which I em loy 1n constructing the wall comprises the front molding-board. 0, rear moldirw-board D, transverse strengthening-pieces E- h, horizontal connecting-rods F and G, ornamental molding-box I, boxq'etaining bars J J, barrctaining rods K K, and stayblocks L, all of which parts are adjustably connected together, as better shown. in Fig.

When constructing a wall formed of different grades of concrete, I preferably employ a screen comprising a plurality of diagonally arranged fingers M, which are connected together at their upper ends by the board N, when. said screen is retained in place upon the edge of the frontboard C by the an ular brackets O, which brackets extend own past the upper edge of said. board. C and bear against its vertical surface, whereby said screen is retained in position. in constructing the first course of tho integrally-brined wall all that part of the ap )arutus shown below the-rods G is dispensed with. When the molding-box, comprising that part of the up paratus above and including the rod (l, is 1n place and the box partially filled with concrete, I first insert the metallic fasteningpicce P, which is preferably formed of a flexile piece of wire or other similar material and is embedded at one end in the concrete,"as

shown within the molding-box in Fi 2,. 1 then insert a longitudinally arrange' molding-board R. When this is done, the molding-box is filled with concrete and'permitted to set and harden, the rod G is withdrawn from the molding-box, the box is'raised a distance corresponding with the distance between said rods F and G, said rod G is againinserted, and said parts are readjusted reparatory to forming the next succee ing course of concrete. The molding board R is then withdrawn from the surface of the wall,

when the ripper ends of the metallic fastening-pieces are inclined upwardly and forwardly, as indicated in the lower courses of. Fig. 2, within the space S, formed by the.

molding-board, which has been removed. This being done, I then insert the moldingbox I in front of the aperture S, when it is re tained in place by the vertical bars J therespective ends of said bars J being held in place by the rods K. Said moldingbox is then filled with concrete or other suitable material in a plastic condition and permitted to harden and form'the ornamental figures desired, as indicated at B. be understood that the box I is provided with an ornamental moldin -surface ada ted to produce any ornamenta finish desired When the concrete or other suitable material has become set and hardened in the mold-I ing-box I, the rods K and the vertical bars J I are withdrawn, when the molding-box I is removed, thus leaving the ornamental piece B in place, as indicated in the lower section of It will of course said Fl s. 1 and 2.v Thisbeing done, the entire mo ding apparatus is raised a distance corresponding with the section of the wall thus completed, when the rods K are inserted in the same a ertures in which the rods G have been wit drawn. Said parts are again adjusted and refil suitable material and the process described again and continuousl' repeated until the wall is finished. It wi l of'course be under-i stood that the concrete or other materialof which said omamental .ieces are formed will set and harden. around t e metallic rctainin wires P, whereby the same is securely helll in place. 7

hile 1 have shown and described the, "l?

molding-box I as retained in place led with concrete or other :rality of transversely-arranged rods K and '.vert1cal-bars-J, I do not Wish'to limit myself tolthe'use'only of said rods and bars for such 5 may be secured to the Wall in a reat variety of otheryvays. For exam 'le, w en the ornamental pieces are,-'as usua located above or ,below a, Windowfor doorway the clamping mechanism may be located in such Windowto opening or doorway, when theretainingrods K may-be dispensed with.

While theornamental pieces Bjinay, if 'de- 1 sired, be formed as the wall is being con- ,structed', 'it is obvi'ous,"if-de sired, that the 15 entire wall'i'nay' first be made, with the aperturesflS, before the ornamental pieces B are made,=whe'n the ornamental ieces'B may be formed after the entire build ng is completed.

.thu'sfdescribed my invention, what 29 lgclaunas new,v and desire to secure by LettersPatent,is

1' '11. The process hereinv described'of forming "O namental work upon the front surface of- .integrally-formed concrete walls, consistin 25 first, inv depositing concrete in an adjustable molding-box around a suitable molding: board adapted to form a recess in the front surface of 'the wall-Section zsedond, permitting the concrete thus deposited to set-and go harden around the molding-board Within" said 'molding-box; third, ralsin'g and readjusting the molding-box and removing the molding-board; fourth,v inserting an-ornamental molding-box in front of the recess 3 5 formed by said moldingboard; fifth, filling said molding-box with concrete or other suit-.

fpurpose, as it is obvious that the molding-box ornament formed by said molding-board; fourth, se

seasee able material; and sixth, in again removing, ralsmg, readgustmg and refilling said moldmg apparatus as each successive course is formed, until the Wall is completed substan-' tially as set Jorth;
