Title: Concrete block forming machine with pneumatic vibration
IPC: B28B3/02
Filed: 1966-01-24
Abstract: 1,132,434. Moulding concrete blocks. COLUMBIA MACHINE Inc. 24 Jan., 1966 [27 Jan., 1965], No. 3102/66. Heading B5A. Apparatus for making concrete blocks comprises a vertical frame, means for suspending and vibrating a mould within the frame, and a pallet lying loosely on a pallet holder mounted below the mould, the pallet holder being supported on air-filled cylinders or cushions by which the pallet can be raised into contact with the lower surface of the mould. The mould 31 is mounted in a frame 69 which is vibrated vertically by collars 78 mounted eccentrically on shaft 80. The mould base is formed by pallet 103 which rests on pallet holder 101 loosely attached to member 23 by bolts 27 and resting on springs 107 and pneumatic pistons 105. Member 23 is rigidly connected to horizontal bar 21 and which is connected to vertical sleeves 7. Bar 8 joining the sleeves 7 is connected at its midpoint to piston 10 of stripper cylinder 11 secured to bracket 13 attached to the main frame 1. Sprung side pieces 17 limit the travel of bar 8. Rods 50 mounted at the base by springs 57 and pivoted links to bar 60 and at the top to cross member 47 serve to absorb sudden shocks on the mould. A set of valves are also supplied so that by means of a pressure regulator, the pressure in pistons 105 can be set to any one of several predetermined values. Different pressures may be used at different points in the cycle, e.g. during filling and vibrating and these may be controlled manually or automatically. The mould, pallet and pallet holder are arranged to have different amplitudes of vibration. In operation, for part of the cycle the mould will be clear of the pallet and the pallet will also clear the pallet holder. As the pallet bonds it will be twisted by springs 107 and this will produce a trowelling effect on the base of the concrete block. Motion of the block relative to the mould produces a similar effect on its sides. Excess water and air can escape from the top and bottom of the block, but no leakage of concrete occurs at the base.

Abstract: 1,155,798. Feeding webs. ROCKFORD SERVO CORP. 23 Jan., 1968 [23 Feb., 1967], No. 3542/68. Heading B8R. Apparatus for actuating a servomotor 15 operating a web-guiding device 21 or a winding roll to maintain transverse register of the web comprises (1) a sensing head 10 embracing the edge of the web W and having spaced discharge and sensing orifices 27, 28 respectively emitting opposed streams of air; (2) a centrifugal air pump 11 supplying air at a constant low pressure and connected to the discharge orifice 27 by an unrestricted conduit and connected to the sensing orifice 28 by a conduit having a flow restrictor so that a relatively high velocity stream of air tends to pass from the orifice 27 towards the orifice 28; and (3) a device 13 responsive to changes in pressure at the sensing orifice 28 caused by deviations in the path of the web edge, and operating a valve 45 to supply pressure fluid to the servomotor 15 so as to actuate the web-guiding device to restore the web to the required position. As shown, air passes from a multi-stage centrifugal air pump 11 with a filter 93 at its intake, to a chamber 100 connected by a conduit 141 to the discharge orifice 27. The chamber 100 is also connected to the sensing orifice 28 via a restricted passage 152, a conduit 153, a chamber C2 on the underside of a diaphragm 41 forming part of the pressure-responsive device 13, and conduits 148, 144. The movable member 55 of the valve 45 is connected to the diaphragm 41, the latter being subject to the action of a spring 58 and to atmospheric pressure on its upper face. The body of the valve 45 is immersed in a reservoir 17 for hydraulic fluid, and fluid can be drawn from the reservoir by a gear type pump 16 via a filter and pipe 123 and supplied to a central groove 47a in the valve body via a pipe 125 having a relief valve 128 and filter 129. Movement of the valve member 55 is effected by variations in the air pressure in the chamber C2 due to movement of the web edge causing greater or less resistance to the flow of air from the orifice 27 into the orifice 28. Such movement causes hydraulic pressure fluid to flow through one of the outlet passages 48b, 48c of the valve 45 to the servomotor 15 through pipes 135, 136, and to be exhausted through the other passage, so that the guiding device 21 is moved to align the web transversely. The device 21 shown comprises one or more web-engaging rollers 181 supported on a Structure 183 movable along arcuate rails 184 having a common centre as described in Specification 1,110,379.
