To all to 7mm it may concern Be it known that we, BAsrL SGRUBY and Gnonon Kn'rrnLwnLr. HARKNnss, both subjects oi the King of Great'Britain, both residing in Harlow, England, have jointly invented certain new and useful Improvements in or Relating to Molds for Use in Building Walls, Making Blocks, Slabs, Tiles, or Briquettes, of which the following is a specification.
- This invention relates to bottomless molds tor moulding concrete or other plastic materials in building walls in situ contiguously section by section and course by course or in making separate blocks, slabs, tiles and the like, the molds being of the kind that comprise each two end. members and two side mold plates, and means whereby the side plates can be moved indirections away from or towards the central longitudinal plane of the mold, withoutchange of their upright or moulding position, for the purpose ott expanding or of closing the mold and so that on completion of a moulding operation an operator can. after the'side plates have been thus withdrawn from engagement with the moulded material, readi- 1y lift the mold and leave the sides of the moulded material or a moulder block tree.
The invention consists in an improved form of theabove type otmold as hereinafter described with reference to the accompanying drawings.
In the improved mold the two side mold plates are so arranged that when they are operated to expand the mold they have a combined upward and outward movement and when they are shifted for the purpose of closing the mold they hauea combined inward and downward movement.
The improved mold comprises a frame, consisting of two end members held apart by rigid connecting pieces, the two side mold plates being mounted on or hinged. to the said frame.
The end members of the frame are the end members of the mold and they may be so formed that themold has either two closedor two open ends, or is closed at one end and open at the other. Stops, linings, partitions, or cores of any suitable known description may, when desired, be placed in the mold to produce any required design of block. i
The invention will be further described with reference to the accompanying drawbe opened or expanded.
|ngs, in which Fig. l is a perspective View of oneitorm and construction of the improved mold, one end thereof being closed and the other open; Fig. 2 is a cross section ot'the mold in Fig. 1 looking in the direction o'f the closed end, thefsides being in the normal or closed. position. Fig. 3 is a section looking in the direction of the open end .oi the mold, the sides being in the expanded or open position. Fig. 4 is a plan of .amold with two closed ends, a liner or plate for forming a key being arranged in the mold at each end. Fig. 5 is a plan view showing amoditied form of side members, said members being shown in closed position.
In the drawings (t represents an end member Ofii'tllB outer frame having a form or shape adapted to close in an end of a mold, and 2') indicates an end member which is adapted to leaveone end of a mold open. The side mold plates aredenoted by c. In constructing the improved mold two end membersare placed at any desired distance apart and are held rigidly in position by means of suitable rigid connections, such as the bars a which are shown secured to the end members a or o, by pairs of nuts 6.
The side plates 0 are mounted or supported on the frame in any convenient manner, but so, that they can be made to approach or recede from one another according as the mold is to be closed laterally or In the mold illus trated in Figs. 1 to 3, the side plates 0 are hinged to the connecting member (Z by means of wire'rod pieces f which are supported in eyes 9 provided in brackets or lugs g on the side plates 0, with their cranked ends 7" embracing the members (Z.
The lugs g arearranged' at such heights that when the sides of the mold are in the normal, closed or moulding position, the axis of each of the wire rods f will be substantially level or deadcentral with the axis of the adjacent member (Z. So long as the said axes occupy these positions, and the terminal portions of the wire rods f do not move away from the dead centre lines, such as line i Fig. 2, the sides will remain locked and immovable under the action of any direct pressure transmitted thereto by material deposited in the mold. By raising the sides so that the rods move away from the dead centre, the sides can be retracted or expanded so far as the connect ng member block that has been formed in the mold free The sides a are provided with means to prevent themnioving below the dead centre; such means may consist of stops j attached to the sides, and adapted to engage with the member d when the portions f lie in the dead centre lines. i
For raising or manipulating the sides 0, handles it are fixed thereto. These handles may he so positioned that when the side plates 0 are in the normal or operative position thehandles will rest upon the upper ineniberscl and thereby serve to prevent the sides from passing below the dead centres." In such case the stops 9' referred to above inayfbe dispensed with. The top edges of the sides 0 when these are in normal or operative position, would be level with the top edge of the closed end member or ends a of the mold. The bottom edges oi the sides 0 may be level with the bottom edges of the end member a or they may, as is customary, extend lower down, as shown at c in Figs. 1., 2 and 3, so that when the mold is used to mould a block of material placed on the top of a block or layer already formed, such extended portions will engage with or embrace the sides of the previously termed. block or layer, it it be of the same width. i ln'this way the side surtacesotthe supei-posed hloclcs or layers will be thus Kept sions plumb. 1 I M To guide the side ineinbers o in the r mo sent when air-open end member 7) is usediras in l, angle pieces Z may beattachod. by 011601 their limbs to the side member. and in such a manner that their other liinliwill hear upon. theinner face of theeiul ineinbe ll 'desii'ed, sides 0 niayi, as shown in Fig.

It it be desired to form blocks which,
ahen'placed end-on in .a row, will be keyed together, loose key plat'e'or lining maybe placed at each end of a mold as shown in l' ig. l.

When such 7 open Z) o'li'the mold with its sides in norinalposition is placed end on to it and .iii a manner to overlap the block more or less; "Concrete orothei' material is then placed in the mold, being thereby moulded on to the end of the block.

In this way portions areadded'in succession along the length of the wall until thelayer'i's com plete- The terminal portion'ot the 'layer may consist of it separately formed block similar to the commencing poi-tion ot the layer; When the layer is sufficiently dry or hard tobear the weight of thesuperposed layer, this supergosed layer can be proceeded with in the same mannen The improved moldcan be used in forming lintels or other parts of a wall or in moulding blocks or joists that are reinforced with longitudinally directed rods. In such cas s the end or ends a would be provided vith holes through which the rods would pass. ll here the rods are continuous, entering the open end 6 of a mold and traversing the holes in the closed end a, the mold can he slid along the rods into successive positions to form a continuous lintel or other reinforced part.
