This invention relates J to continuously travelling mold forms for use in connection.

with the formation of-m'onolithicconcrete wall's, columns, and floor beams of buildlng "structures.

A general object of this invention to provide a continuously movable mold'form for not only pouringthe outer wallsv ofa building structure, but'in additionthereto forming the floor supporting'columns, and

.at suitable intervals the floor beams con-v nected to the columns all monolithically. I

1 Briefly, the" invention disclosed herein consists of a continuously movable mold form similar to the one illustrated and described in my co-pending; application en'titledOoncrete wall'construc'tion, SerialNo. '12'Z,73 9,

lVhen the movable forms reaclithe position shown in Fig. where floorbeams20 should be formed, bottom mold beam boards 31 are placed in position in the same manner as in the first described form with the braces 32 in position to support the beam ,see Fig.

12. ,After the brace supports 31 are in place the nails -are pulled in order'to disconnect u thewalls A+ from the forms, and wall boards B are placed inposition, their lower ends 51Ubeing disposed above'the upper ends of boards A- a distance equalling the thickness of abeam, the openings 34 permitting the concrete to'fiow therethrough to the beam molds, as in the first construc tion.

The travelling forms continue'their upward movement until'their upper edges are flush with the upper ends'ofthe mold walls i B when the nails 50 are again employed I to fasten the mold walls to the forms (see Fig. 17) so thatfthey will move therewith up to'the pointwhere another beam is to be formed, It will be understood that the mold board CT and D that lie against the inner face of the outer. walls are manipu- 'lated in exactly the same manner. the lower edge. of thetravelling forms pass the upper; ends of the mold boards A-.'
