Abstract: This relates to a label applicator for applying labels to mold cavities of rotating mold units. The label applicator is fixed relative to moving mold units and includes an extensible fluid motor which carries a pick-up head or suction head for moving the suction head in a straight line direction and return. The extensible fluid motor is carried by a shaft for oscillation between a label pick-up position and a label deposit position. The extensible fluid motor is carried by a bracket which, in turn, is carried by a shaft of a rotary actuator which is constructed to oscillate between two fixed positions which are spaced apart a preselected angular distance. There is incorporated with the rotary actuator a decelerator for rapidly, yet smoothly, decelerating rotation of the bracket carrying the extensible fluid motor. Suitable sensor means are provided for timing the actuation of the label applicator in accordance with the position of a mold cavity into which a label is to be placed.

The apparatus is comprised of a fixed frame, two movable frame portions, four mold members, two cam rod members, and a cam shaft. The two movable frame members are movably connected to the fixed frame. The four mold members are positioned on the two movable frame members, the mold members being movable relative to one another. The two cam rod members are secured to the fixed frame, and the cam shaft member is mounted on one of the mold members. When the movable frame members are moved relative to the fixed frame, they cause the cam shaft to move along one of the cam rod members, thus causing two of the mold members to be pulled away from the remaining two mold members, thereby stretching the filament connecting portion of the attachment device.

Abstract: For casting large concrete articles, a wheel-mounted main frame supports a mould assembly which can be rotated about a horizontal axis, and also raised and lowered. This assembly has two main mould sections oppositely arranged so that when one faces upwards the other faces downwards. A removable mould section fitted to each main mould section forms a complete mould capable, when uppermost, of receiving concrete to be cast. The mould assembly may then be inverted and lowered to a support, and the removable mould section disconnected to serve as a pallet for the cast article. The mould assembly may be raised, concrete may be cast in the other mould, which is uppermost, and the main frame may be moved clear of the deposited cast article.
