To all whom 'it may concern:

Be itknown that I, DAVID J. ANDREW, n citizen of the United States, residingat Lawrence, in the county of Middlesex and StateV of Massachusetts, have invented certain new and useful Improvements in Concrete Buildings andMethods of Making lthe Same; and I do hereby declare the following to be a full, clear, and exact description o f the invention, such as will lenable others skilled in the art to 4which' it appertains to make and use the same.

The present invention relates'to concrete buildings and to an improved method of r erecting such structures.

Prior to the present invention it has been proposed to erect what is known in the art as a l reinforced concretel buildlngv by vconstructing temporary wooden frames or molds 4 .for the various parts of such buildings which are to be made of concrete, and toprogressively, as the building advances in height, deliver into such molds the concrete mixture which surrounds and incloses the reinforcing metallic bars placed in po-sition in said molds, and after the concrete mixture has set suiiciently, the frames or molds are removed and this process is progressively advanced until the reinforced concrete structure-has attained itsdesired height. It has further beenl proposed to erect a building, suchv as dwelling house, in sucha manner as to produce when completed a monolithic concrete structure, and it has been suggested that this could be done by providing sui-table metal mold-s which could beset up' at" the location of Vthe proposed building and the concrete mixture poured into such molds ina semi-'liquid -form and allowed to set while protected and inclosed `by the molds for a suliicient length of time to harden, after which the molds 'are to bei removed, leaving the building in a -practically complete state with; .the exception of the finish. The first method has been found to bey objectionablek by reason' of itscomparatively slow and costly procedure, and by reason of the large `waste of material in both molds and struc- -ture, a large amount of material being em-l 'ployed'in't-he structure unrequired to sup-` port it or to resist the: elements. With regard to the second method proposed of molding or casting a monolithic bu-ildingin its entirety, the cost of 'the molds renders the use of the method Aunadapted to any purpose 'except the erection of a large number of houses or structures of identical design. -There 1s a constantly increasing demand, however, for concrete' buildlngs and more is with the object of producing such buildlngs 'of individual design in an expeditious duced quantity of materials of const-ruction, thatI-have produced-my present linventlon.

of'a concrete building and the method 'of after set forth and claimed.

The invention vfurther consistsof the im'- proved monolithic section or panel for concrete buildingswhich will be hereinafter described and claimed. l

My invention isillustrated in-the accompanyi'ng drawings in which:

dwelling housev embodying the same.- Fig. 2 is a section taken on line 2, 2 of ig.' l; Fig. 3 isan enlz tr, ,'ed view ofthe central poron` line 4, 4 of Fig. l.

In carrying out my invention I cast or mold of any suitable concrete mixture the panels l' wliichniay be of any desiredsize,

or panels 1V will be of a size to form a considerable part ofthe walls of the building 'to be erected, and as .shown .in lthe'drawing they are of a size to'extend entirely across the building from side to side' and lof a height corresponding to the height between the floors or Vstories of the building.

In the process of casting or molding, the anels 1 will be provided with suitable open- -ings 2 for the windows and doors'. The sections or panels 1v it lwill be understood are cast or, molded previous ,to beginning the erect-ion ofthe building, and are allowed to removal from the molds andtheir handling the wall-of the building by means of a cast or a molded monolithic frame or casing inof the sections or panels f1 and comprises the sill 4, the belt course 5, and the cornice and plate 6 extending` between and connecting the corner posts 8 and'9, whichframe is cast particularly forv concrete dwellings, and it manner, atsinall expense,'and of greatly retion of Fig. 2, and Fig. 4 is a section taken` shape or thickness.:l Preferably the sections` set al suflicient length of time to permit their dicatedv in a general wayby thereference character, which as shown in Fig. 1 of the drawing, entirely surrounds the outer edges eol To the above ends my invention consists i constructing the same which will be herein- Figure 1 shows a front elevation of a in the 'course of constructing the building, and they are held in lace and supported in 'tureand they are strengthene or molded in position in the house or build. ing and about the edges of the previously molded and erected sections or panels.

Briey thenmy' invent-ion may be said to consist of the employment of previouslymolded sectionsor panels set in position in the wall of the building and secured therein by a surrounding and inclosing supporting frame of concrete material cast or molded in place during the construction of the build?l 4 will be molded or castinfposition in the structure and will be provided along its upper edge with a rabbetedrecess into which the ylower edge of the lower sect-ion l will be embedded.

The house wil-lconsist of the vpreviously cast or molded sections inclosed by the cast or molded 'retaining frame which when set forms practically a monolithic structure.

'The word anel as used in the claims is intended to eiine any form of section .of

whatever shape or design vadapted to be.

united-to other panels of the same or diiierent shape lby a castor molded frame.

The expression concrete, as herein employed,'is intended to include any form of plastic material which is capable of bein@ cast or molded and thereafter becomes solid and strong.

Having thus described the invention what is claimed is l 1.Y rlhe vmethod `of constructing the walls 'of concrete buildings which consists in mold- .embraces the -upper e ing .or casting a suitable number of concrete panels and allowing them to harden, each of said panels being of suitable width and of a height substantially' equal to the distance between the floors of the. building desired, ar-

ranging' a plurality 4of said panels in their nal position to inclose the first floor, casting a sill at the base of said panels and casting vertical posts connecting ladjacent panels, then lacing a second seriesof panels above sai yiirst floor panels, to inclose the second floor, casting a belt course around the adjacent edges of the first and second door panels and casting vertical posts connecting adjacent panels of said lsecond floor course, continuing said operation until walls of the desired height are produced, then casting a cornice on the top edges of the upper series of panels, saidl sill, vertical posts, belt courses and cornice being so cast as to form a monolithic frame for said panels.

2. The method of constructing the walls of concrete buildings which consists in molding or casting a suitable number of concrete panels and allowing them to harden, each of said panels being of suitable width and of a height substantially equal to the distance loefx tween the floors of the building desired, arranging a plurality of said panels in their inalposition to inclose the first iioor, casting a sill at'the base of said panels, casting vertical posts connecting adjacent panels, and casting a belt course irder section which ges of said panels, saidsill, vertical posts and belt course girder section being'so cast as to form a monolithic frame which entirely surrounds each panel. In testimony wher'eofl alix my signature, in presence of two witnesses.
