Abstract
Abstract A toy press for molding material such as caramel candy into a predetermined shape comprising a flat plate with an aperture, a cylinder connected to the aperture, and a piston for forcing molding material from the cylinder through the aperture. An interchangeable die which is pressed against the flat plate defines a mold cavity with an outline larger than the aperture in the plate, to permit one-piece dies to be used. The die is transparent or translucent to enable observation of mold filling.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
A toy press comprising: a housing; molding means removably mounted in said housing, said molding means defining a first member having a substantially flat surface with an aperture therein; a cylinder on said first member communicating with said aperture in said molding means, for holding molding material; a piston movably mounted in said housing for movement in said cylinder; means for moving said piston through said cylinder; said molding means including a second member comprising a die having a mold cavity open at only one face thereof, and larger at said one face than said aperture in said flat surface of said molding means, including a portion about said cavity bearing against said flat surface at positions spaced outwardly from the edges of said hole; and holding means for releasably holding said die against said flat surface of said first member, whereby to form molded pieces with outlines defined by said die, said die being constructed of material which can be seen through at least partially, to enable observation of the progress of mold filling.
Claim 2
Dependent Claim
175 words
A toy press comprising: a housing; molding means removably mounted in said housing, said molding means defining a first member having a substantially flat surface with an aperture therein; a cylinder on said first member communicating with said aperture in said molding means, for holding molding material; a piston movably mounted in said housing for movement in said cylinder; means for moving said piston through said cylinder; said molding means including a second member comprising a die having a mold cavity open at only one face thereof, and larger at said one face than said aperture in said flat surface of said molding means, including a portion about said cavity bearing against said flat surface at positions spaced outwardly from the edges of said hole; and holding means for releasably holding said die against said flat surface of said first member, whereby to form molded pieces with outlines defined by said die, said die being constructed of material which can be seen through at least partially, to enable observation of the progress of mold filling.
Claim 3
Dependent Claim
129 words
A toy press comprising: a housing having a platform with a receiving aperture therein, and having a threaded upper portion; a molding member having a plate portion for resting on said platform and a cylinder portion for depending through said receiving aperture; a piston member with a lower portion of smaller cross section than the hollow of said cylinder to enable it to drop therethrough; means mounted on said housing for raising said piston member; a die having a cavity and walls about said cavity for resting on said plate portion of said molding member; and a cap having a thread for screwing onto said threaded upper portion and a portion for bearing against said die to hold said die tight against said plate portion of said molding member.
Claim 4
Dependent Claim
129 words
A toy press comprising: a housing having a platform with a receiving aperture therein, and having a threaded upper portion; a molding member having a plate portion for resting on said platform and a cylinder portion for depending through said receiving aperture; a piston member with a lower portion of smaller cross section than the hollow of said cylinder to enable it to drop therethrough; means mounted on said housing for raising said piston member; a die having a cavity and walls about said cavity for resting on said plate portion of said molding member; and a cap having a thread for screwing onto said threaded upper portion and a portion for bearing against said die to hold said die tight against said plate portion of said molding member.
Claim 5
Dependent Claim
43 words
The Toy press described in claim 2 wherein: said walls of said die about said cavity form a ridge, for supporting said die on said plate portion only at the area immediately about said die cavity, whereby to promote sealing of said cavity.
Claim 6
Dependent Claim
39 words
The toy press described in claim 2 wherein: said die is constructed of a material with a transparency at least that of translucent material; and said cap has a central portion devoid of opaque material for viewing said die.
Claim 7
Dependent Claim
44 words
The toy press described in claim 2 including: retaining means for holding said molding member to said housing while allowing said die to be lifted from said housing, whereby to facilitate removal of a molded piece which tends to stick to said molding member.
Claim 8
Dependent Claim
165 words
A toy press comprising: a housing; molding means removably mounted in said housing, said molding means defining a first member having a substantially flat surface with an aperture therein; a cylinder on said first member communicating with said aperture in said molding means, for holding molding material; a piston movably mounted in said housing for movement in said cylinder; means for moving said piston through said cylinder; said molding means including a second member comprising a die having a mold cavity open at only one face thereof, and larger at said one face than said aperture in said flat surface bearing against said flat surface at positions spaced outwardly from the edges of said hole; holding means for releasably holding said die against said flat surface of said first member, whereby to form molded pieces with outlines defined by said die, said holding means comprising a cap with threads thereon for threadably engaging said housing to press said die means hard against said molding means.
Claim 9
Dependent Claim
165 words
A toy press comprising: a housing; molding means removably mounted in said housing, said molding means defining a first member having a substantially flat surface with an aperture therein; a cylinder on said first member communicating with said aperture in said molding means, for holding molding material; a piston movably mounted in said housing for movement in said cylinder; means for moving said piston through said cylinder; said molding means including a second member comprising a die having a mold cavity open at only one face thereof, and larger at said one face than said aperture in said flat surface bearing against said flat surface at positions spaced outwardly from the edges of said hole; holding means for releasably holding said die against said flat surface of said first member, whereby to form molded pieces with outlines defined by said die, said holding means comprising a cap with threads thereon for threadably engaging said housing to press said die means hard against said molding means.
