Be it known that weQLEO F. MUL UnnN and PATRICK WALSH, citizensof the United States, residing at Los 'Angles, in the county of Los Angelesand State of California,;have invented certain new and iusefulllmprove ments in Molding 'Maehines;., of which the following isaspejcification' p i q This invention rel tes toniolding'jma-l chines and more particularly tothe type em ployed for molding concrete orsimilarplastic material. p k i It has for an object to provide a construe-e tiOn j which rnay be utilized for directly building solid or hollow Walls from con-. crete.

Tothese and other ends theinvention consi ts of eertain partsland combination of parts to be hereinafter more particularly demaohine, set for one size double-wall and air another adjustment wall and air space.

To operate the molding machine after the sameha's been. adjusted as hereinbeforede'-' scribed,"the"bars 27 are "first, placed on, or into,the foundation walls'upon which'the double wall is to be" built, the 'moliding'ma chineis then set into an open position as hereinafter described, and is 'plaiced'over the said walls to allow the plates 3 andj l to rest onthe bars 27', or on a flat foundation, the

::r moldingmachine is then'closed to bring the plates '1,3,4 and 2 flush with the respective i faces of the'said supporting double wall, and W the wires 26 are then driveninto the several sets of slots 25",and'are bent over the" outerv faces of the said plates 1 and2to preventlthe when concrete, or other plastic materials are tamped therebetween, or between the plates, 1-3, or 4-2 respectively;

To open the.m0lding machine as shown" in Figures 2 and 5,'-it willbeseen' that the nut ,19 slidably inthe slot l8, on the threads. 20, andjto closethe same, the1link15 'is' again" moved in the opposite direction. as hereinbe' their top ends to, suit the width'of thespace; lyin T eplat'es2- 21 m'ayf beusedfto close the air space lying between the plates 3 and 4,120

prevente'th'e concrete or 'other iplastic materials from falling into the "same when being poured into the spaces lying between the p1ates11-j3, and

The cranks 24 may be formed to project the'pins ll and 12 at angular positions from the shafts 13, so as to throw the said pins 11 and'12 aroundtheshafts 13, as the moldingmachine is opened, to allow the plates 1-4; and 372 to move "away from an end ob-' struction, as shown ,in' profile and arrow points in Figure '2.
