My invention has relation more "specin callyto a wallfmold construction of the slip form type for forming .hollow` concrete walls and simultaneously forming a plurality of concrete bonds between the wall members to tie the same together. i

1925 tovClara Y.' Waugh as administratrix ofthe esta-te of l ames H."vVat1gh, deceased-, and assigned'in full to .1ne,.a bonding construction 'was lillustrated and described in i which the yWall members wereheld in bonded relation to each Otherby metal rods having hooked ends. Vlin-order ,to providev for the proper placement of the' metal bonds during thewall pouring operation, relatively Ylong ladderswcarrying metal bonding rods were required to be set inposition prior to the operati-on of pouring the wall members, this procedure not vonly entailing consider able trouble but increasing the cost of erecf: tion. f f i f In the present invention such ladders or supportszfor Inetalbonding rods. are dis- Other ob'ects and advantages will be apparent from vthe following specification, references being had rto the accompanying` drawings forming 'a part thereof, in which: Fig. 1 Vis a transverse vertical section of l the slip form mold in connection with a hollow concretewall construction. f Fig. 2 is a detail perspective view of the ylower portion of the mold orm,illustrating the meansA employed in formingthe concrete CII Wallbondng membrs- ,Fig. 3 .is a v.perspective view of a portion of afinishedV hollow Wall, Showing the concrete rbonds connecting the wall' me`1n- `bers. l' f" Fg- 4' isa Partialplan View 0f al .hllow conoretewall partly in section together with the mold forms.

` `Vv` The bonding` 'members 491D hS Case which kserve to Atiefthe two wallmembers together are formed wholly of concrete, als

though metal reinforcing rods may be introduced thereinifthought desirable, and are preferably formed' in spaced vertical rows and a dista-nce apart equal to the length of the core boxes `19, as clearly shown in Fig. 3. yEach of the four vertical edges 41 of the core boxes'a're grooved for the reception of wood slide plates 42, and it is thought the infethodof forming `the, bonds may be more readily understoodby a description in connection with Figs.v 6V to 9 inclusivey of the drawings.v In Fig.v 6, the movable slipform is illustrated in position at the foundation 30 Vof thewall members, in this position slip boards 42 are iirstplaced in the corner grooves ofthe oppositely disposed ends of two adjacent 4core boxes 19, 'the height of 1. these board are approximately o-ne half of the height'of tlieyb'oxes.v Cross boards 43, .are then laid across the upper ends of boards 42, their ends proj ecting'slightly beyond the side lfaces of the core boxes, see Fig. 2. Concrete is then poured between the mold forms to a height just above the boards43, (see Fig.y 7) Vand metal reinforcing rods 44 may 'be then introducedV ifdesired.l After the sainerhave been placed in position other slip boards 45 exactly similar toy boards 42l are s inserted in the corner grooves of the core vboxes, their lower ends being disposed above 4the crossboards 43 a distance equal to the ydesired thickness of the bond. The pouring of concrete in the moldsis'again resumed as v 'shown in Fig. 8, the wet concrete pouring throughthe openings formed by the cross boards 43 andthe lower ends of the slide 'boards 45 and forming a complete concrete bond between lthe wall members.

After the above described operations are lcompleted the slip forms are moved up' reassess wardly to the position shown in Fig. 9, when p vothercross boards 43 rare again laidfacross the upper ends of the lower slide boards 42, asy described and shown in Fig. 6. The above operations are Vcontinued until the en# tire wall members have been poured, the concrete bonds 40 being foi-'med at regular intervals as shown in Fig. 3. f yIt will be understood that when the forms are moved upwardly in order. to add to the heightof the wall members, the slip boards 42 will be held against movement byV their adhesion to the inner faces of the formed' wall members, but if found desirable they may be knocked out of place after the'walls have been formed. 1 c Y It will be readily apparent from ,the above description that by the employment of core boxes in a slip form construction and spacing the abutting endsin spaced relation, in combination with side slipboards and cross boards thatl concrete'bonds maybe formed at regular intervals between the two wall members asthe lconcrete is poured, the bonds as effectively tyingy the'walls members together as the metal bonds ontlie rods in the patented structure hereinbefore referred to'. lWhat lclaim is: 'y Y LA concrete mold form` comprising a movable mold form consisting of a plurality of walls spaced apart to form moldcavities adapted to be utilized in the formation of a pair of hollow wall members, and means connected to some of said mold forniwalls and removable therewithfor forming a plurality of concrete bonding members adapted to connect or tie the wall members together as the same are poured'.
