Abstract
Abstract A two-piece mold for producing shaped units of formable material such as snow and the like, and for handling and positioning the shaped units. One piece of the mold provides three sides and at least one open end, and the second piece provides the fourth side and an end closure. The two mold pieces are slidably mated along their edges to an assembled condition in which the first and second pieces are secured to provide an open topped, closed bottom mold. After snow or other shape-holding material is packed into the mold through the open top, and sets its shape, the filled mold is inverted. With the second piece held in place, the three-sided element is drawn past the fixed end closure which is now positioned at the top until the three-sided element is separated. The second element including the end closure is moved laterally from the resulting block of shaped material to leave the shaped unit standing free where initially positioned. The first and second elements of the mold can then be mated for reuse.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
A mold for producing shaped units of formable material comprising a first and second element, said first element comprising laterally disposed partial enclosure means having two open ends, and one open side, said second element comprising side closure means for said open side of said first element, and end closure means for only one of said open ends, said side closure means and said end closure means being fixed with respect to each other, said side closure means including slidable securing means for mating said second element with said first element with said end closure means traveling through said open end and within said first element during said mating; stop means for limiting the extreme of said traveling to position said end closure means adjacent an end of said first element opposite said open end.
Claim 2
Dependent Claim
135 words
A mold for producing shaped units of formable material comprising a first and second element, said first element comprising laterally disposed partial enclosure means having two open ends, and one open side, said second element comprising side closure means for said open side of said first element, and end closure means for only one of said open ends, said side closure means and said end closure means being fixed with respect to each other, said side closure means including slidable securing means for mating said second element with said first element with said end closure means traveling through said open end and within said first element during said mating; stop means for limiting the extreme of said traveling to position said end closure means adjacent an end of said first element opposite said open end.
Claim 3
Dependent Claim
41 words
The mold of claim 1 wherein said slidable securing means comprises rib means extending along the entire length adjacent both edges of one of said members, and mating grooves extending along the length adjacent edges of the other of said members.
Claim 4
Dependent Claim
51 words
The mold of claim 1 wherein said stop means comprises flange means extending transversely across the end of opposing side walls of said first element at the end thereof opposite said open end of said mold, and wherein said flange means extend outwardly of said side walls to provide handle means.
Claim 5
Dependent Claim
129 words
A four-sided mold for producing blocks comprising a first and second element, said first element comprising a three-sided enclosure means having two open ends, and one open side, said second element comprising a fourth side of said mold and only one end closure member for closing only one of said open ends, said fourth side and said end closure member being secured with respect to each other, said mold including mating means for slidably securing edges of said fourth side to the sides of said first element adjacent to the open side thereof, said first element including stop means for limiting the mating movement of said second element at one extreme of said movement so that the end closure member is properly positioned as a bottom of said mold.
Claim 6
Dependent Claim
129 words
A four-sided mold for producing blocks comprising a first and second element, said first element comprising a three-sided enclosure means having two open ends, and one open side, said second element comprising a fourth side of said mold and only one end closure member for closing only one of said open ends, said fourth side and said end closure member being secured with respect to each other, said mold including mating means for slidably securing edges of said fourth side to the sides of said first element adjacent to the open side thereof, said first element including stop means for limiting the mating movement of said second element at one extreme of said movement so that the end closure member is properly positioned as a bottom of said mold.
Claim 7
Dependent Claim
47 words
The mold of claim 4 wherein said mating means comprises rib means extending along the entire length adjacent both edges of one of said members, and grooves mating with said rib means, said grooves extending along the length adjacent the edges of the other of said members.
