Abstract
Abstract Apparatus for molding articles having a base, a pair of side plates hinged thereto for movement to and from a lowered position and a raised position in opposed relation, said base and side plates forming a mold cavity when said side plates are raised, and means for retaining said side plates in raised position to provide said cavity. In one form, an end plate may also be provided hinged to said base for movement to and from a lowered and a raised position. When said side and end plates are in raised position, they may be interlocked in the latter position to maintain said cavity.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
189 words
Molding apparatus for molding articles with an insert comprising a base, a pair of opposed side panels hingedly carried by said base and each movable from a lowered, inactive position to a raised, upright, active position to form with said base an open-topped mold cavity, an end plate also hingedly carried by said base in proximity to said side panels and also movable from a lowered, inactive position to a raised, upright, active position against the ends of said side panels when said side panels are in their said raised positions, and locking means positioned below the open top of said mold cavity for releasably locking said side panels and said end plate to each other in their reSpective raised positions whereby to insure maintaining said mold cavity, said base having attachment means thereon for releasably and selectively securing a mold element within said mold cavity, said apparatus being characterized in that each side panel has a flange at its upper end when it is in its said raised position, and characterized further in that each said flange has associated therewith means for applying downward pressure to said insert.
Claim 2
Dependent Claim
189 words
Molding apparatus for molding articles with an insert comprising a base, a pair of opposed side panels hingedly carried by said base and each movable from a lowered, inactive position to a raised, upright, active position to form with said base an open-topped mold cavity, an end plate also hingedly carried by said base in proximity to said side panels and also movable from a lowered, inactive position to a raised, upright, active position against the ends of said side panels when said side panels are in their said raised positions, and locking means positioned below the open top of said mold cavity for releasably locking said side panels and said end plate to each other in their reSpective raised positions whereby to insure maintaining said mold cavity, said base having attachment means thereon for releasably and selectively securing a mold element within said mold cavity, said apparatus being characterized in that each side panel has a flange at its upper end when it is in its said raised position, and characterized further in that each said flange has associated therewith means for applying downward pressure to said insert.
Claim 3
Dependent Claim
38 words
Molding apparatus according to claim 1 characterized in that said end plate and said side panels are so mounted on said base that when they are in their respective said lowered positions, they are in substantially coplanar relation.
Claim 4
Dependent Claim
30 words
Molding apparatus according to claim 1 characterized in that when said side panels are in their respective said raised positions, they are inclined toward each other in an upward direction.
Claim 5
Dependent Claim
33 words
Molding apparatus according to claim 1 wherein said base comprises a wooden base having a floor plate thereon, and wherein said panels and said end plate are hingedly connected to said floor plate.
Claim 6
Dependent Claim
51 words
Molding apparatus according to claim 1 wherein said pressure applying means comprises a separate lever pivotally carried by each said flange, and characterized further in that each said lever has pivotally coupled thereto a bearing plate adapted to engage said insert and to apply pressure thereto when said levers are lowered.
Claim 7
Dependent Claim
44 words
Molding apparatus according to claim 1 characterized in that each of said flanges supports a pivotally mounted lever, and a separate bearing plate associated with each said lever in a position to engage said insert for applying pressure thereon when its lever is lowered.
Claim 8
Dependent Claim
27 words
Molding apparatus according to claim 6 wherein each of said flanges has a lug thereon, and wherein said levers are pivotally connected to the respective said lugs.
Claim 9
Dependent Claim
42 words
Molding apparatus according to claim 6 wherein each of said flanges has a lug thereon, said levers being respectively pivotally connected to separate ones of said lugs and extending over said molding cavity when said panels are in their said raised positions.
Claim 10
Dependent Claim
56 words
Molding apparatus according to claim 1 wherein said end plate has side wings adapted to embrace and abut against said side panels, and characterized by said locking means being constructed and arranged to cooperate with said side wings and with said side panels for maintaining said side panels and said end plate in raised, cooperative relation.
