Application filed June 2, 1920.- Serial No. 385,913.

dence at 4.0 First avenue, in the city of Ot-' d of the Wall C.

tawa, Canada, have invented certain new an useful Improvements in Molds for Constructing Concrete Houses and other Buildings, of which the following is a specification.

This invention relates to improvements in molds for constructing complete all concrete continuous cavity buildings, and the objects of the invention are to provide a simple and easily operated set of molds which may be used for building concrete houses, and other structures, and by the use of which an improved hygienic and sanitary type of building may be erected at low cost and in a minimum space of time, and it consists essentially of a novel set of corner and extension standards adapted to support the mold boards in combination with continuous cavity standards and extension mold supporting members all constructed and arranged as hereinafter more fully set forth and described in the accompanying specification and drawings.

In the drawings:

Figure 1 is a sectional ment of the invention. a

Fig. 2 is a perspective view of the cavity corner standard. 7

Fig. 3 is a perspective view of the inner corner standard.

Fig. 4c is a perspective view of the cavity extension standard.

Fig. 5 is a sectional detail through the outer extension standard- 1 Fig. 6 is a sectional elevation.

' Fig. 7' is an elevation of the cam member.

Fig. 8 is a sectional detail in the cam tightening member.

In the drawings, like characters of reference indicate corresponding parts in all the figures.

The drawing represents the invention applied, to the molds for concrete houses, in which the walls are constructed with a central cavity. 7

Referring to plan of an embodithe drawings, A indicates the outside corner standard, it comprising an outer corner angle member 10, and an inner angle member 11 connected together by

shaped braces

12 and 13, which are riveted or otherwise rigidly attached toeach angle member, the said angle members belng spaced apart to form sockets or recesses to receive the molding members or planks B, which are designed to mold the outer surface D indicates the inner corner member, which also comprises substantially parallel outer and inner angle members 14 and 15, connected by L-

shaped braces

16 and 17, and each of the angle members forming sockets to receive the molding members or planks E which mold the inner surface of the wall. When the wall is long it is necessary to provide extension standards or holding members for the molding member.

F represents these extension standards, each comprising an outer plate 18 and an inner plate 19, which are spaced apart and form sockets for the mold member, the plates being reinforced on the inner side by longitudinally extending

angle bars

20 and 21, which in closed position overlap as shown.

The plates are held in closed position by means of clamping dimension screws 22, which extend through the outer plates into threaded sockets 23, which are secured in position to form an inner plate 19, and which screw bolts govern the thickness of the boards.

A plurality of clamping dimension screws are provided and constructed with respect to each other, and formed with handles 24: by which they may be turned and which also form an abutment against the outer plates, to rovide rigidity.

represents a cavity corner standard or retaining member adapted to support and hold the molding members which mold the surface of the central cavity in the wall, this member Gr comprising an outer angle member 25, and an inner angle member 26, the said angle members having

bracket members

27 and 28 designed to overlap and formed with perforations 29 through which a central locking bar 30 is designed to be inserted, thus holding the corner members in extended rigid position.

Each of the

angle members

25 and 26 is formed with one section 31 parallel with one wall, one section 32 parallel with the other wall which is atright angles to the first wall, and an angular connecting portion 33.

The inner molding members H are secured to the

angle members

25 and 26, and are maintained in spread position by vertically extending cam members 34:.

represents the cavity extension standards or supporting members provided where necessary throughout the length of the wall to connect the cavity molding member, each of the said cavity extension standards including

parallel side plates

35 and 36, having overlapping perforated brackets or lugs 37 and 38 designed to receive a central locking pin 39, the

plates

35 and 36 being suitably reinforced with angle members 40 and having at intervals threaded sockets 41 designed to receive transversely extending threaded locking pins which extend through locking pins 42, which extend through the walls into the socket, the opposing plate as well as the extension standards F being formed with suitable perforations to permit the passage of such pins.

The

plates

35 and 36 and mold members connected to them are held in extended position by transversely extending bolt members 413.

To give additional strength to the molding members when in position, I provide bracing members J and K on the outside and inside respectively, each including

angle members

50 and 51, separated by spacers 52, the webs of the angle members extending outwardly from the mold boards, and being connected by clamping bolts 53 extending through the spacers 52, these bolts extending through all the molding members from one of the brace members J to the other K, having suitable clamping nuts thereon adapted to bear against the brace members.

11 additional ,bracing and adjusting bolt L is provided extending diagonally through the corner standards, the nuts of which bear against washers 55 and 56 hearing against the outside and inside corner standards.

represents a plurality of cam ties which are in the form of thin strips of metal of U-shaped formation embedded in the concrete and form a support for the bottom of b be left in the withdrawn as the cam bars and designed to wall when the cam bars are hereinafter explained.

In using the invention the various standards or mold supporting members are placed in position as indicated in Fig. 1, the mold board members placed in position and the concrete board allowed to set, the cams 34 being previously turned to expanding position. After the concrete is set the cams 34 are moved to released position which p.er mits the cavity stands or molds supporting members to collapse, permitting the cavity molding members H to collapse and be withdrawn from the cavity. The mold members on the outer and inner walls may also be withdrawn leaving the finished walls.

Window, doors" and other convenience may be provided for in the house by suitable openings around which suitable forms of molds are provided.

As many changes could be made in the above construction, and many apparently widely diflerent embodiments of my invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, itis intended that all mat.- ter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

IV hat I claim as my invention is:

1. In a mold for concrete plates, a cavity mold board supporting member, comprising a pair of plates adapted to be secured to the mold board, overlapping brackets on the plates, a line of perforations, and a pin adapted to extend through the said perforations.
