ALEXANDER CHAMBLEY, OF PHILADELPHIA, PENNSYLVANIA.

MOLD FOR CONCRETE SLABS AND THE LIKE.

T0 all whom it may concern:

Be it known that I, ALEXANDER CHAM- BLEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Molds for Concrete Slabs and thelike, of which the following is a specification.

- T he invention relates to concrete and masonry structures and more particularly to the apparatus for the production of the same, and has for an object to provide a mold for use informing slabs, blocks or the like, from concrete or other plastic materials.

The invention comprehends among other features, the provision of a mold which is of a simple construction and because of the simplicity of its parts, can be cheaply manufactured, the mold being particularly designed for the purpose of molding concrete slabs for use in building construction, as in the flooring thereof, or for any other purposes to which a slab of such character, may be adapted.

In the further disclosure of the invention, reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which,

Figure 1 is a plan View of the mold.

Fig. 2 is a bottom plan view.

Fig.3 is a fragmentary vertical longitudinal sectional view taken on the line 3-3 in Fig. 1. I

Fig. 4- is a fragmentary vertical transverse sectional view taken on the line H in Fig. 1, and

Fig. 5 is a fragmentary enlarged detail showing the manner of securing the reinforcing strips or elements.

Referring more particularly to the views, I provide a base 10 which is preferably of a rectangular shape and which includes sides 11 and ends 12, the sides and ends being of channel shape in cross section as shown, with the sides and ends suitably secured together by suitable angle pieces 13. The superstructure for the base comprises an outer shaping section 1 1, and an inner shaping section 15, each preferably made of sheet metal with the outer section formed of sides 16 and ends 17, secured together by suitable angle plates or pieces 18. It will be noted that the sides Specification of Letters Patent.

Serial No. 305,733.

and ends are slightly inclined, this being preferably provided in order that the outer shaping section 1% can be removed after the cement has set. The inner shaping section 15 consists of substantially a single piece of sheet metahwhich is pressed into shape to provide a floor or base 19 and an inverted bowl shaped portion 20 with the floor or base 19 adapted to repose upon the base 10, as shown, suitable'reinforcing uprights or plates 21, being secured to the inner faces of the sides 11, and projecting upwardly into the bowllike portion 20 so as to suitably reinforce and uphold this portion of the inner shaping section. It will be noted that the outer shaping section has its sides and ends suitably reinforced with angular strips 22, any number of which may be employed and which extend longitudinally of the sides and ends and aid materially in providing a rigid structure.

A substantially rectangular ledge 23 is provided and is formed with a seat 2 1, said ledge being disposed upon the floor or base portion 19 of the inner shaping section and in substantially superposition to the base 10 with suitable bolts or screws passing through the led e 23 and the floor or base 19, into the sides and ends of the base 10, to rigidly secure the ledge in position. The seat 24 provided on the ledge, is adapted to receive and supportv the outer shaping section 14, as shown, and which outer shaping section is removable, as will be hereinafter more fully disclosed.

In the use of the mold described, assuming that the parts are as shown in Figs. 1 to 1 inclusive, the mixture of a plastic material such as cement or the like, is poured in between the inner and outer shaping sections and will of course conform to the space provided by these sections. When the cement or other plastic material has hardened or set, the outer shaping section is lifted, being entirely removed from the ledge 23, thus permitting of readily lifting the finished or molded slab and which entirely constructed of metal, can of course be used over many times and because of the material and character or" its formation, will Withstand great Wear and tear, tl e particular elements and pieces making up the mold, serving to provide a construction Which can be practically made out of stock ma terial and therefore can be cheaply nianur'actured.

Having described my invention, 1 clain1,

1. A mold for slabs and the like, comprising a base including inverted channel shaped ends and sides, an inner shaping section having an inverted boWl-like portion and a floor portion with said floor portion reposing upon said base, a ledge on said floor portion and secured to the base, means for reinforcin said inner shaping section at the bowl-1i re portion thereof, an outer shaping section including relatively inclined connected sides and ends, said outer shaping section being reniovably disposed upon said ledge, and means on the sides and ends of said outer shaping section and serving to reinforce the same.

2. A mold for slabs and the like, C0111- prising a base, an inner shaping section carried by and supported on said base, means on the base and associated with the inner shaping section to reinforce the latter, a ledge in superposition to the base and secured to the latter and an outer shaping section reniovably disposed on said ledge in spaced relation to said inner shaping section.

8. A mold for slabs and the like, comprising a base, an inner shaping section supported on said base,-a ledge in superposition to said base, and an outer shaping section having relatively inclined sides and ends and removably disposed upon said ledge in superposition to said base, and in spaced relation to the inner shaping section.

In testimony whereof I, aifix niy signature.

ALEXANDER CHAMBLEY.
