'ing the plates in position.

ERNEST e. KEMPER, or sit. Louis; urssonar.


To all} whom it may concern.-

Be it known thatI, ERNEST G. KEMPER, a

citizen ofthe United States, and a resident of St. Louis, State of Missouri, have invented certain new and useful Improvements in the Art of Making Imitation-Stone Fronts, of which the following is a specification.

This invention relates to improvements in the art of making imitation-stone fronts; and it consists in the novel arrangement, construction, and combination of parts, as will be fully hereinafter described and claimed.

The object of my invention is to construct panels or plates provided. with suitable flanges whereby one maybe attached to and sup orted to the other and provided with a sur' ace designed to form imitation stone front on a wall of concrete.

A further object of my invention is to build a wall of concrete on the face ofwhich is imprinted an imitation-stone surface, which is done by applying a plurality of plates having faces to imitate stone, and after the wall of cement has sufliciently set the plates can be removed. I

In the drawings, Figure 1 is a perspective view of a portion of a wall, showing my invention in relative position during the art of formingthe stone front. Fig. 2 is a vertical sectional view of a portion of the wall, show- Fig. 3 is a per spective view of a plate showing the adjustable feature'. Fig. 4 is a perspective view with parts broken away and in section of a plate with its flange adjustable- Fig. 5 is a detail verticalsectional view of the same, showing the use of the adjustable flange. In the construction of myinvention I provide a plate of sheet metal 6, rovidedwith flanges 7, 8, 9, and 10. The ace 11, out of which these flanges are formed, is rov'ided with a surface bent and shaped to orm-the configuration of a' stone or builders rock.

The flanges 8 and 9 are provided with rightangular projecting flanges 12 and 13. These flanges are formed integral and bent out of the same materiaL'and the flange 13 at its center is provided with a recess 14, through which a wire 15 is adapted to be passed and supported by means of a. pin 16, passing through the loop formed on the ends of the wire. The purpose of the wire 15 is to retain the plates in parallel position when the con-, crete is placed "between them.

by means of the flan es, are interlocked, as

shown in Fig. 1 and t e same in building one Specification of Letters Patent.

upon the other are staggered, as in the mauner of laying rock or brick, so that the ends of the plates are in alinement with the. recesses 141, thus forminga support for each other.

In building a wall of this character the latcs are built one upon the other to a heig t desired and placed apartat a width sufficient for the thickness of the wall to be built. The.

rear or inner plates 17 are similar in constanction, but have their contacting faces corrugated, as indicated by the numeral 18. I'Vhen the wall is built to the height" desired, the concrete is lodged between the plates and the same coming in contact with the surfaces of these lat-es will form on the front surface a stone ace, while in the rear will be formed a corrugatedface, upon which is applied the plaster for the interior of the room, and by means of the corrugations the plaster wil have a perfect and-rigid adhering surface.

In instances where it is desired to use a short pl at'e for example, at the corner of the wall-and to dispense with cutting the plate to fit such requirements I design a plate, as shown in'Fig' 3, composed of twosections 19 and 20. Section 19 is provided with two projecting pins 21, which operate through slots 22, formed in the section 20, and on these ins are placed thumb-nuts 23, which by tig tening the same will rigidly secure toflanges are rigidly secured together when adjusted. To construct a wall of this character, especially where it is desired to extend it to a great height, stiffening-tubes 28 are placed at intervals. throughout the walls, and around these is located the concrete which forms the wall, and after the plates have been removed from the outer surface of the wall the im rint .of the faces thereof resembles that of roc asshown by the numeral 29.

Having fully described my invention, what I claim, and desire to have secured to me by Letters Patent, is-

1. A'd'evice of the character described comprising a plate, rectangular flanges formed on said plate, a right-angular projection formed on two of said flanges, one of said projections I rising plates having irregular surfaces to provided with a recess for the insertion of a orm the configuration of stone, flang Wire, and an irregular surface formed on the 1519339 to resemble rock. substantially as specie I v 2. A device of the character described comprisin plates provided with flanges and rectangu ar projections whereby one late may be placed against the other, one'ofsaid rec'- tangular projections provided with a recess through'whi'ch is passed a wire for locking the same together when in osition; and having faces to imitate the 'co g-uration of-ston'e on a body of cement placed between them, substantially as s ecified'-.

3. A device of t e character described comes formed integral with said plate, rectangu ar proj ections formed on two of said flanges, and adjusting means wherebysaid plate may be shortened if desired, andan adjustable flan e whereby an ofiset may be formed on the wa l, substantially as specified.

In testimony whereof I have signed my 2 5,

name to this specification in presence oftwo subscribing witnesses.
