Abstract: An improved means for supporting an elongated device for pouring concrete pipe, pile and similar devices. The means makes use of pins movably supporting a device for pouring concrete inside of a concrete molding frame and support levers support the concrete pouring device outside of the frame in order to prevent the concrete pouring pipe from being flexed with its own weight.

Abstract: Smooth and uniform concrete floor or roof sections of channel formation with metal reinforcement are produced by linear movement of a slip form guided by relatively stationary rails which mold the side faces of the channel sections. Skid members which follow the rails also serve to mold the top linear edges of the concrete channel sections. The proper placement of a welded reinforcing grid is achieved by a forward adjustable template and the wall thickness and internal radii of the molded channel are established by a rearward adjustable template. The cooperating templates provide a concrete hopper structure on the slip form.

Abstract: A pipe mold for vertically cast concrete pipe includes a cylindrical outer mold case, a cylindrical core spaced inside the mold case, and a pipe-reinforcing cylinder between the core and the case. A system for casting concrete in the pipe mold includes a flat facing ring above the annular space between the mold case and the cylinder. A chute assembly mounted concentrically above the pipe mold includes several radially extending and spaced apart pouring chutes extending downwardly from the center of the chute assembly to corresponding circumferentially spaced apart openings in the facing ring. The pouring chutes channel the flow of concrete into the openings in the facing ring to fill the pipe mold to the bottom surface of the facing ring, which forms a flat annular end section at the desired elevation on the pipe. The facing ring eliminates the need for hand finishing and measuring which is common in the prior art manufacture of vertically cast concrete pipe.

Abstract: A slip casting apparatus comprising a supply tank, a reserve well in communication with said tank, a pump means to pump said slip from said tank through a delivery means to casting molds and having provision for continuously recycling the slip in and out of the supply tank. The same pump is utilized both to deliver slip to casting molds and to recirculate slip within the supply tank, in a manner which eliminates settling and relieves the pump from undue pressure. This apparatus has application for use with other liquids of similar characteristics. The well also functions to prevent the formation of air bubbles.

Abstract: An apparatus for forming ice cubes mold means are provided having walls that define a plurality of separate cavities. A resilient, pliable empty bag is brought into engagement in a mold to be frozen and is placed in contact with the mold means. Preferably the mold means is comprised of two mold sections between which is sandwiched the liquid pliable package which because of its inherent resiliency and pliability the liquid filled package conforms to the shape of the cavities in the mold means. Passageways are provided that interconnect adjacent ones of the cavities so that the resulting frozen articles are connected to each other by readily frangible sections. In one form of the invention a reservoir is provided for containing the liquid to be frozen as well as a plurality of conduit means that are used for filling a number of the pliable packages positioned within the mold means.
