Claim 1
Independent Claim
216 words
A method of manufacture and assembly of preformed building units, each unit being cast integrally and having a top element and a side element forming a substantially right angle unit comprising the steps of: providing a form on a previously cast first unit for receiving flowable material to produce a superimposed second unit thereon with the previously cast first unit providing the bottom for the new top element and one side form for the new side element, pouring flowable material into said form and allowing it to set, providing a form on said second unit for receiving flowable material to produce a superimposed third unit with the previously cast second unit providing the bottom for the new top element and one side form for the new side element, pouring flowable material into the third unit form and allowing it to set, raising said second unit to break bond and suction with the first unit, and moving said second unit horizontally to place the second unit in a predetermined position, and lowering said second unit producing a supporting relationship of the second unit top element with the first unit top element, and continuing with said raising, moving, and lowering steps to produce a supporting relationship of the third unit top element with the second unit top element.

Claim 3
Dependent Claim
26 words

Claim 4
Dependent Claim
22 words
A method as defined in claim 1 and wherein said third unit is cast during the moving of the second unit horizontally.
Claim 5
Dependent Claim
19 words
