Patent number: 9011137Abstract: A mold and method for making a hollow core concrete block. The mold has two opposing side walls; a bottom wall; a front wall; a top side with an opening through which the block can be removed from the mold; a cover, and a rear side through which liquid, such as concrete, can be poured into the mold. Extending from the two side walls are a pair of trunnions about which the mold is rotatable, such that when the mold is suspended by the trunnions and the mold is empty, gravity rotates the mold from a block-removal orientation in which the top side faces upwards to a mold-filling orientation in which the rear side faces upwards. The trunnions are also positioned such that when the mold is filled with the liquid, gravity rotates the mold from the mold-filling orientation to the block-removal orientation.Type: GrantFiled: July 15, 2011Date of Patent: April 21, 2015Assignee: Magnum Forms Inc.Inventors: Robert Garrett, Arthur Garrett

Patent number: 8323715Abstract: The complementary parts of food products destined to be coupled together are located on the frontal surfaces of half-moulds travelling on two different loop conveyor lines. The first conveyor line extends, at least partially, above the second, so to be included within the surface area occupied by the second line itself. Spatial occupation is further reduced since, downstream to the coupling station, the coupled half-moulds travel with the same spacing step that they had before coupling, with additional advantages in terms of energy absorption and advancing velocity in a successive thermal conditioning station, such as a refrigerating tunnel. One of the half-moulds can be removed upstream to the thermal conditioning station, resulting in an additional reduction in energy absorption since needless subjecting of the half-mould to the thermal cycle to which the products are subjected is avoided.Type: GrantFiled: February 27, 2008Date of Patent: December 4, 2012Assignee: Soremartec S.A.Inventors: Luciano Massa, Giovanni Sobrero

The machine is provided with a mechanism for inserting sticks into the partially frozen confection material, means for defrosting the exterior of the cavities to facilitate removal of the frozen confections and a selectively operable device responsive to the inadvertent retention of confection material in one or more cavities to remove the retained confection material by inverting the mold bar and spraying hot water into the cavities to remove the confection material. Moreover the confection machine provides laterally opposed to chains circulating in a closed path in which one reach of the chain, the working reach, associated with filling, freezing, stick insertion and confection removal devices and a return reach.Type: GrantFiled: April 27, 1984Date of Patent: March 18, 1986Assignee: FMC CorporationInventor: David N. Anderson

Patent number: 4527940Abstract: A machine for automatically removing a block of cheese from a container having an open top by inverting the container and pulling the cheese through the inverted open top by retractable suction cups. The cheese containers are vertically stacked on a hydraulic lift which raises the containers to an elevated position where the topmost container is gripped by a plurality of pressure actuated clamps. The clamps are mounted on a horizontal frame which is pivoted through a 180.degree. vertical arc to invert the clamped container so that the heretofore open top becomes an open bottom. A plurality of suction cups are mounted on a vertically movable conveyor which is located beneath the container when the container is in the inverted position. The conveyor and suction cups are raised to a position closely adjacent the open bottom of the container by pressure actuated cylinders and the suction cups engage the block of cheese.Type: GrantFiled: August 15, 1983Date of Patent: July 9, 1985Assignee: Biery Cheese CompanyInventor: Dennis H. Biery

Patent number: 4472130Abstract: The invention provides devices for raising a table for casting a concrete panel so as to be able to remove it from the mold. Such a raising device is provided with a funicular cable passing over an assembly of pulleys. Two carriages carried by two strands of this funicular cable travel perpendicularly to the pivoting axis of the table and with an identical movement. Two links are pivotably mounted on these carriages and on the lower face of the table so as to synchronize the raising movement of said table.Type: GrantFiled: July 8, 1982Date of Patent: September 18, 1984Assignee: Societe d'Etudes Techniques et d'Entreprises Generales-SodetegInventors: Philippe Demonsablon, Jean Millot, Andre Corneloup

Patent number: 4311087Abstract: Multi-cavity molds coact with respective table elements forming a drainage table. Between each mold and the corresponding table element is a connecting means allowing the mold to slide between a normal cheese-draining position against the table element and a cleaning position spaced from the table element. The connecting means include abutments limiting said sliding of the mold and on which the mold is supported in said cleaning position thereof.Type: GrantFiled: February 19, 1980Date of Patent: January 19, 1982Assignee: Alfa-Laval S.A.Inventor: Gerrit E. Brinkman

Patent number: 4296908Abstract: A mold having an integral piece for casting a hygienic-sanitary appliance is disclosed. The mold includes a lower mold piece, at least two lateral mold pieces which are mounted on the lower mold piece to define a molding cavity for an article to be cast. An upper mold piece is mounted in position on the lateral mold pieces to close the mold cavity; the lateral and upper mold pieces being separable from the lower mold piece and the cast article to leave the latter resting on the lower mold piece. Below the cavity of the mold there is provided an annular or partially annular shaped base to support the cast article.Type: GrantFiled: July 28, 1980Date of Patent: October 27, 1981Assignee: American Standard Inc.Inventor: Giuseppe Lippa

Patent number: 4248578Abstract: A process for molding a cheese piece of a desired shape comprises filling a mold having a hollow interior of the desired shape with softened, uncured cheese, cooling the mold to harden and partially cure the cheese, and then opening the mold to release the cheese piece under the surface of a cold brine so that the fluid pressure of the brine prevents the shape of the partially cured cheese piece from being distorted. An apparatus for automatically performing the described method is disclosed.Type: GrantFiled: June 21, 1978Date of Patent: February 3, 1981Assignee: Stainless Steel Fabricating, Inc.Inventor: Donald G. Worden

Patent number: 4181485Abstract: Method and apparatus for the manufacture of pre-cast plate-like concrete elements on a building site. A horizontal casting table has a large area mold into which the concrete is poured. After a short setting time to allow the concrete to harden, the table is raised to a vertical position and the partially hardened concrete element is drawn off of the mold. The process of moving the table to a vertical condition is accompanied by a lateral movement such that the latest element is stacked at the head of a line of previously cast elements. The elements are allowed to stand undisturbed until hardening is complete. Casting is done in a movable shed which shelters the partially hardened elements from the weather. Ribbed elements may be cast using a further mold element raised and lowered from the ceiling of the shed.Type: GrantFiled: November 14, 1977Date of Patent: January 1, 1980Inventor: Horst Schramm

Patent number: 4149697Abstract: An outfit for manufacturing concrete units includes one frame, which can move along a rail-track, and two detachable forms-tilters on it. The length of the unit made in the forms can be varied. Each form has also detachable equipment (edges, dies, and dividing bars). Before stripping the units, the side edges of the form are thrown aside and the bottom edge is taken away. A detachable hinged clip which is fixed on the bottom side is moved into a working position. Then the form is turned over 90.degree., and the outfit moves to a rack. The top edge is thrown back, the clip is released, and the unit falls down on cushions. The outfit operates in the same manner on the other side of the rail-track. It is possible to manufacture in one form two or more units at the same time with corresponding increase in quantity of clips on the bottom side of the form.Type: GrantFiled: February 7, 1978Date of Patent: April 17, 1979Inventor: Mikhail Linetsky
