This invention relates to molds and has special reference to inner-and outer forms by which blocks, walls or other structures may be econoincallyand expeditiously -produced from plastic materiah` asconcrete.v
The primary object of my invention is to provide innerfouter and finishing forms that may be assembled for the con-struction of a ivalh the inner and outer form determining` the thicknesses ofthe walls, and the iinishing' forms the nature of the exposed surfaces of the walls, itbeinp; possible to provide a Wall with a finishing surface in imitation of brick7 tile or any building' material. I* Another object of my invention to provide a novel'mold core for the pi'tmliiction of" hollow concrete blocks or tiles, the core w ils being' shiftable and arranged to be distended or retracted by mechanism within the core` and the saine mechanism is arranged so that it may be easily operated and will afford meansby which the core may be manipulatedrelative to a moldor outer form. v r i.
'A further object of this invention is to provide outer molds or forms which may be built up similar to a wall and afford ready means for the attachment of scaffolds or platform supports? which will permit of a wall beine' progressively formed Awhile other parts of the wall are being` set or curved.V
A still further object of this invention is to provide a finishing; form that may be 1.ilaced alcanst a concrete wall and a facing molded on the wall; or the facing; may be first placed on the wall and then the finishing form used to make an impression in the facing. In either instance the wall may have a face in imitation of any well known building` material.
The above and other objects are attained by a construction that will'be hereinafter described and then claimed, and reference will now be had to the drawings, wherein Figure 1 is a plan of a mold core or inner form; Y
Fig. 2 is a longtudinal sectional View of the same partly broken away;
Fig.' 8 is a perspective view of a portion of the mold core; Fig. 4 is a perspective view of a portion of a wall showingr my inner and outer forms as being used in the formation of said wall;

- Fig. 8 is ahorizontal sectional view,` of a portion ofthe finishingform,v and Fig. 'QI-is al sectional View, similar to Fig. 7'showing the iinishingform in ay reverse position. y vReference willl first be'had toFigs. 1 to 2l inclusive showing the-collapsible core or inner form used' in theV production of hollow wallsyblocks, tiles or the like.V .The core comprisesannleplates l. 2,3 and4 and these plates are assembled so' that the edges` thereofr will overlap as ato, and all-of said angle plates cooperate inl formingl the core that has end-and side wallsrproviding a structure` rectangular in cross section.
Intermediate the ends of the angle plates are angle barsy 7 andat the angles of the plates 1 to Ll-'inclusive are flat bars 6'.. The angle bars 7 of the plates land 3 are opposed to the ang-les 7` of the plates2 andy 4 and are connected by links 8.: Similar links 9 connect the. 'flat .bars y6 and inconsequence of such link connections theY angle plates l and 3 can be shifted-relative to the angle plates 2 and-`4 preferably by raisingr one sety of anp-le plates relative. to the other. it the overl.apping` edges of the angle piatesl and is avertically disposed coniectinpv bar 10, pivotally connectedby a series of toggle members 11 to the angle bars .71 of the angle plates 1 and 3, so. that when the connecting bar 10 1s raised the angle plate 1 will be drawn towards the angleV plate 3. n
' Pivotally connected to the angle bar 7 of the angle plate 3 is an operating lever 12 pivotally connected, as at 13, to the upper endiof the connecting` bai-10, and said operating lever .has an inset handle portion 14. Thefangle plates 2 and 4 are articulated in a manner similar to the angle plates l and 3 and the levers 12 may be used for bodily lifting the collapsible core.
At the upper edges of the angle plates 1 and 3 are angle ledges 15 which will facilitate placing one yCore on top of another. Reference will now be 4had to Figs. 4 and 5 showing t-he outer forms used in the formation of a concrete block 16 or a hollow wall 17; one of the hollow portions of the wall having a collapsible core therein. Each outer form comprises a rectangular frame 18 provided with a wall plate 19 and in each frame is one or more braces 20, according to the'length of each outer form. For the formation of the wallr17 the outer forms areV1 st-acked one on the other, in staggered relation and maybe suitably connected together and braced relative to the collapsible cores during the pouring and tampering of concreteor other plastic material between the inner and outer forms. The
frames 18 are adapted to support platform y or scaffold brackets 21 so that a wall of considerable height may be conveniently formed. y i
In the formation of theconcrete block 16 corner pieces 22 are` used in connection with the frames 18 anda collapsible core. Any suitable means may be employed for connecting or holding the frames 18 and thev tion or ofsuch shape as to be readily with.
f drawn from a plasticfacing 26 placed on the Wall 17. The plasticfacing may be of any7 material that will harden on the wall 17 in imitation of any building material, for instance bricks or tiles. As shown in Fig. 7 the facing die may be placed against the wall 17 and the interstices filled with the plastic facing 26. lVlie-n thev facing die is Withdrawn the plastic facing will leave lines of demarkation similar to laid bricks or tiles,
Y asshown in Fig. 6.
In some instances the facing material may may quickly construct `an artistic concrete wall, and it is in this connection that the form of dies forshaping and ornamenting the exterior surface of the concrete wall.

. What Iclaim isz- J 1. A collapsible core comprising frontand rear wall sections, each `comprising a pair of relatively `extensible angle plates, toggle means for extending said plates, a lever for the operation of said `toggle means, links connectingthe front wall sections to the rear.
wall sections, and means whereby one of said sections may be lifted relatively to the other to facilitate removal of said core from a moldV after use.
2. A collapsible core according to claim 1,
wherein the angleplates are movable in constant overlapping planes and the front and rear wall sections are adapted to vertical movement and movement one towards thel other by virtue ofverticall swingable links connecting said front sections to said rear sections.
3. collapsible core according to claim 1 wherein a plurality of said toggle means are provided in the form of links connectedV A at their outer ends to said angle plates and at their inner ends Vto a common vertically disposed operating bar, and a leveneffecting the vertical movement of said bar.
