Serial No. 813,878.
To all whom/1'2, may concern Be it known that I, CHARLES H. acitizen of the United States, dent of Kenosha, inthe county of Kenosha and State of lVisconsin, have invented a new and Improved Mold for lValls, of which the following is a full, clear, and exact description.
An object of my invention is to provide a wall mold having members so formed and arranged that upon the mold being placed in position, the members will automatically assume the proper positionsto form the de sired space for the material to be molded, and upon lifting the mold the members will autmiatically be given a separating lateral movement.
A further object of my invention is to provide a mold for walls in which molding elements are so mounted that upon the mold being lifted after the wall or wall section is formed, a vertical gravitational movement of inner members of the mold relatively to the outer members will cause a relative separating movemenet of the outer members.
sisting of spaced members between which the upper ends of the end hangers l0 and 12 are received. The hangers 10 are pivotally secured to the cross bars It by pivot bolts 15 on which the sides may swing.
The core sections are mounted for vertical movement in the frame elements, and are arranged to collapse toward each other when the mold is lifted. The connection between the upper ends of the hangers 12 of the mold sections and the cross bars H is effected by means of slots and pins, there being op positely inclined slots 16 in the ends 12, and pins 17 and through the cross bars. To give further guided movement to the mold sections plates 18 are fixed to the cross bars ll, and depend therefrom, and a slot and pin connectimi is efi'ected between each core section and the plates 18, there being oppositely inclined slots 19 in the ends 12 below the slots 16, and pins 20 in fixed relation to the plates 18 extend into the slots 19. Thus parallel movement of the core sections toward and from each other may be produced in the collaps- Harms, and a resi- The invention consists in a mold having mg and expanding of the core. the novel construction and arrangement provide means to cause an outward hereinafter particularly described.
Reference is to be had to the accompanying drawers forming a part of this specifi cation, in which similar characters of refer ence indicate corresponding parts in all the views.
Figure 1 is a perspective view of a wall mold constructed in accordance with my invention; Fig. 2 is a transverse vertical section showing the mold in use; Fig. 3 is a view similar to Fig. 2, showing the mold with the parts in the position they assume when the mold is being lifted from the wall,'or being placed in position thereon; and Fig. 4 is a fragmentary plan view with parts being broken out.
In constructing awall mold in accordance with the illustrated example, side members, are provided, here shown as consisting of end hangers 10, between which are's'ecured suitable facing members, here shown as consisting of metallic sheets 11. A core is provided to form a hollow wall, said core consisting of end hangers 12 and facin sheets 13, the latter being preferably of metal. The sides and the core sections are suspended from lift frame elements, there being transverse supporting bars 14 swinging of the sides 10, 11 by a relative vertical movement of the core sections. In the illustrated example the said means consists of toggle links 21, which are pivotally secured to the sides by means of bolts the said toggle links being received between the end hangers l0 and strips 1O corresponding in general form with said hangers and disposed outside of the links 21, the strips 10 being secured at their upper ends by the pivot bolts 15 for suspending the hangers 10. To effect adjustment between the swinging sides and the ends of the a series of holes 21 through any of which the pivot bolts 22 may be passed. The toggle links are pivotally connected also with the hangers 12 of the core sections, the con nection being effected in the instance shown, by the pin 23 which connects the overlapping ends of the toggle links 21, and passes also through blocks Qlwhich are seated in opposed recesses 25 formed in the hangers 12 of the core sections. The construction is such that the core sections may have a parallel movement toward and from each other by reason of the blocks 24 and recesses 25, and there is alsoa pivotal movement of at each end of the mold, each cross bar con l the toggle linkson their pins 23. To faciliextending through said slots toggle links, the latter are provided withtate the lifting of the mold, handles 26 may be provided, these being conveniently secured to the plates 18. i
In using my improved mold the workmen will lift the same and drop it in the position where the wall is to be molded, a portion of the wall being indicated by the letter A. So long as the mold is suspended by the handies 26 or otherwise, the core sections 12, 13, will assume the collapsed position in close relation to each other, as indicated in Fig. 3. When the mold is lowered, the core will be arrested by striking against the base on which the wall is to be erected, and later, a-
downward movement of the core will be arrested by transverse reinforce members, ties, or anchors such as indicated at B. The arrest of the core will relieve the side molds 10. 11 of 'the weight of the core, and there will be a relative vertical movement of the core and sides, permitting the sides to move toward each other and assume the parallel position indicated in Fig. 2. At the same time the relative upward movement of the core sections will cause the same to be expanded by reason of the described slot and pin connections. The material to be molded may now be deposited in the mold between the respective sides and the side sections of the core; The upper portions of the metallic sheets 11 of the sides are preferably deflected outwardly to act as guards against the splashing of the concrete or other material. The wall having been molded to a height within the capacity of the mold, and having been permitted to set sufficiently, the mold is lifted, whereupon ment of the core sections relatively to the frame will result in causing a collapsing movement of the same toward each other, by reason of the slot and pin connection, and at the same time the relative downward movement of the core sections will act on the the vertical movetoggle links 21, straightening out the same, which will swing the side molds 1O, 11, on their pivots 15. It will thus be seen that the lifting of the mold causes the core sections to collapse toward each other, and the side molds to be swung outward clear of the wall.
Having thus described my invention, claim as new and desire to secure by Letters Patent:
1. A mold, comprising frame elements, sides suspended from the said frame elements and mounted for movement toward and from each other, a core formed of side sections movable toward and from each other, said sections having guided vertical movement on the frame members, and links pivotally connected with the core sections and with the suspended sides.
2. A mold, comprising sframe elements, sides pi votally hung on said frame elements, a core formed of gravitationally collapsible side sections having guided movement on the frame elements, and links pivotally connected with the core sections and with the pivoted sides. i
3. A mold. comprising frame elements,
sides pivotally mounted on said frame elements, a core formed of side sections vertically slidable on the frameelements, members in fixed relation to the frame elements,
connections between said fixed members and he core sections, said connections consisting of oppositely inclined slots and pins in said slots, and toggle links pivotally connected with the pivoted side sections and pivotally connected with the core sections.
in testimony whereof I have signed my name to this specification in the presence of t [W subscribing witnesses.
