Abstract
Abstract A molding device for forming a shaped object from a soft moldable material. The device includes at least one die having a mold cavity which cooperates with a second die or a forming plate, to form a three-dimensional object. By manipulating a handle assembly which forms a part of the device, the moldable material is forced into the mold cavity(ies), so that such material assumes the shape of the mold cavity.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
159 words
A molding device comprising a base member, a pair of spaced apart upright support members secured at one end to said base member, a handle assembly, means for attaching one end of said handle to at least one of said upright members so that it is pivotable about a transverse axis extending between said upright members and movable along a vertical axis normal to said transverse axis, a platen, means for securing said platen to said handle assembly so that it is positioned between said upright members for movement along said vertical axis, at least one die having a mold cavity, means cooperating with said die for forming an object having a prescribed configuration, and means for removably securing said die and said cooperating means to the molding device so that they are interposed between the platen and the base member, and one of them is secured to said platen and the other is secured to said base member.
Claim 2
Dependent Claim
159 words
A molding device comprising a base member, a pair of spaced apart upright support members secured at one end to said base member, a handle assembly, means for attaching one end of said handle to at least one of said upright members so that it is pivotable about a transverse axis extending between said upright members and movable along a vertical axis normal to said transverse axis, a platen, means for securing said platen to said handle assembly so that it is positioned between said upright members for movement along said vertical axis, at least one die having a mold cavity, means cooperating with said die for forming an object having a prescribed configuration, and means for removably securing said die and said cooperating means to the molding device so that they are interposed between the platen and the base member, and one of them is secured to said platen and the other is secured to said base member.
Claim 3
Dependent Claim
68 words
The combination of claim 1 wherein the means for attaching the handle to the upright support member includes a shaft which extends transversely between said support members, means for connection said shaft to said support members for movement along said vertical axis, said handle assembly includes a pair of spaced apart arms, and means are provided for rotatably mounting the end of each handle arm on said shaft.
Claim 4
Dependent Claim
29 words
The combination of claim 2 wherein each support member is provided with an inwardly facing vertical side standard, the end portions of said shaft being positioned proximate said standards.
Claim 5
Dependent Claim
41 words
The combination of claim 3 wherein each support member is provided with a vertically extending elongated slot, said slots being positioned proximate the side standards, the ends of said shaft extending into said slot and being retained for vertical movement therein.
Claim 6
Dependent Claim
60 words
The combination oF claim 4 wherein each side standard has a generally rectangular cross-section and a front surface having a rack with a plurality of vertically aligned teeth thereon, said slots being positioned in front of said racks, and the handle assembly includes means for meshing with said rack teeth as said handle is pivoted relative to the support members.
Claim 7
Dependent Claim
63 words
The combination of claim 5 wherein the end of each handle arm includes a plurality of teeth adapted to mesh with the teeth on said racks, said handle teeth becoming disengaged from the teeth on said racks when the handle is pivoted so that it projects upwardly, such upward orientation of the handle permitting the shaft to be moved relative to the slots.
Claim 8
Dependent Claim
43 words
The combination of claim 6 wherein a spur gear is secured to the shaft proximate each of its ends, each spur gear being interposed between a handle arm and a support member and being adapted to mesh with the teeth on said rack.
Claim 9
Dependent Claim
36 words
The combination of claim 3 wherein means are provided for securing the platen to the shaft so that it is interposed between said shaft and the base member, said shaft being rotatable relative to said platen.
Claim 10
Dependent Claim
47 words
The combination of claim 8 wherein said platen includes a side edge proximate each of the vertical standards, and a pair of protrusions are secured to each side edge, the protrusions of each pair being positioned so that an edge of the standards is interposed between them.
Claim 11
Dependent Claim
53 words
The combination of claim 1 wherein the means cooperating with the die comprises a second die having a mold cavity, said mold cavities adapted to form an object having configured front and rear surfaces, said dies being oriented on said platen and said base member so that said mold cavities face each other.
Claim 12
Dependent Claim
30 words
The combination of claim 1 wherein the means cooperating with the die comprises a plate member, said die and said plate cooperating to form an object having one flat surface.
Claim 13
Dependent Claim
143 words
A molding device comprising a base member, a pair of spaced apart upright support members secured at one end to said base member, a handle assembly having a pair of spaced apart arms, a shaft transversely interposed between said support members so that its longitudinal axis is normal to the upright supports, means for movably securing said shaft to the support members so that it is rotatable about its longitudinal axis and movable along a vertical axis normal to said longitudinal axis, means for rotatably connecting the handle arms to said shaft, means for limiting vertical movement of the shaft as the arms are pivoted relative to the shaft, a platen, means for attaching said platen to said shaft, and means for maintaining parallelism between said platen and said base member as the shaft and said platen are moved along the vertical axis.
Claim 14
Dependent Claim
143 words
A molding device comprising a base member, a pair of spaced apart upright support members secured at one end to said base member, a handle assembly having a pair of spaced apart arms, a shaft transversely interposed between said support members so that its longitudinal axis is normal to the upright supports, means for movably securing said shaft to the support members so that it is rotatable about its longitudinal axis and movable along a vertical axis normal to said longitudinal axis, means for rotatably connecting the handle arms to said shaft, means for limiting vertical movement of the shaft as the arms are pivoted relative to the shaft, a platen, means for attaching said platen to said shaft, and means for maintaining parallelism between said platen and said base member as the shaft and said platen are moved along the vertical axis.
