MOLD FORM.
ApplicationfiIed September 18, 1925. Serial No. 57,046.
ing is a full, clear, and exact description,
reference being had to the accompanying drawings.
Thisinventionis concerned with mold forms and more particularly, with mold forms for molding concrete vaults and the general object thereof is to provide a mold structure which can be rapidly assembled to receive the wet concrete, and thereafter be readily removed when once the concrete is set.
More specifically, my invention is directed to the provision of a novel form of top structure which may be fleXedto produce an arcuate surface on the material being molded and which maybe readily 'attached tothe mold in a leak-proof manner with a quickly detachable clamping means.
Other objects of my invention will hereinafter be set forth in the following description referring to the accompanying drawings illustrating a preferred form thereof. The essential characteristics are summarized in the claims.
In. the drawings, Fig. 1 is a perspective View of a mold structure embodying the novelfeatures of my invention; Fig. 2 is a cross-sectional elevation taken through the center of the mold substantially. along the line 22 of Fig. 1; Fig. 3 isan enlarged perspective detail of a corner structure of the mold walls; Fig. 4 is a perspective view of a removable pouringhopper forthe mold; Fig. 5 is a plan view of the top structure or base of the mold structure; Fig; .6is an en-v larged fragmentary perspective detail of one corner of the base structure of the mold; Fig. 7 is a view similar to Fig. 6 showing the mold structure of an opposite corner of the base; and Fig. 8 is a perspective view of the article molded.
Mold forms for the molding of concrete vaults and particularly thoseforms now in use for the molding of lid of concrete vaults embody a core structure mounted on a base and removable outer walls and a top-which may be stripped from the formed concrete before the concrete iscompletely set, whereby the article may be troweled and finished to remove and correct any irregularities incident to. the pouring of the concrete. Such mold forms usually embody a large number of bolts and clamps for securing the sides and end walls and the top together in a leak-proof manner. Due to the usual length of the article to be molded relative to its width, the top andside members frequently warp or buckle under the clamping action to causing deficient proportioningin the lid.
My invention contemplates the provision of a mold construction which may be rapidly removed from the pouredconcrete after it has solidified and before it'has completely set and the. characteristics of the members comprising the mold whereby this re1novability may be obtained, is such that the will have no tendency to warp or buckle.
The preferred forms of mold construction,
which I illustrate in the drawings, is particularly adaptable to the molding of a longitudinal members comprising the mold cover or lid having an arcuate top. ,As
shown in the drawings, the mold may comprise end walls 10 and side walls 11 removably mounted upon a base structure (see Fig. 5) comprising metal-lined longitudinal members'13 and 14 and transverse bottom members 15 and16. These members may be secured to transverse base members 18 and 19 disposed at the ends of the mold structure and to an intermediately disposed base member 20. These latter members ex tend or project from the sides of the base for a purpose to be hereinafter setforth.
Disposed within. the inner marginal boundaries of the bottom members 13, 14,
1.5 and 16, may be a core structure c'omprising longitudinal members 2 1 and 25 and top longitudinal members 26, resting upon end members 28. All of the core members are preferably covered by a metal, lining a 30, extending thereoven' The outer side" 'sl eet metal which maybe longitudinally reinforced in such manner as] to remain slightly flexible. The top structuremay. accordingly comprise longitudinally extending sheet metal members/l0 and 41 spaced apart to provide a pouringgate 42 ;the sheet T fl secured h r-etomad. othc at metal members ll) and 41 being reinforced by longitudinal strips 4A extending over the outside surface thereof. The strips and the sheet metal members may be-oarriedby flat transversely extending band members 15, 46 and 47. Angle members 48 may extend longitudinally along the, top of the closure structure adjacent the pouring gate and form flanges forthe pouring gate; A pouring hopper 50, .,s,h own in Fig. '4, may have .channehshaped: members; 5,1 spaced apart and secured to; the. bottom thereof to ride: upon the-angle members. 48. The lower longitudinal; edges of the metallic membersMl and ll immediately above. the side wall members 11 .maybev reinforced by band members- 4;5, {1.6 and 17. x

From the foregoing. description of the preferred: torus o l? my'ilwention it will: be apparent that the corners of the mold are eliicientl-y closed by the clamping. action of two rods 80, one at each end oi tlie.1no-l(l; that the longitudinal members comprising the side walls arepreveuted from warping outwardly at the bottom by the action of. the plates positionedon thev transverse members.
