Title: Formation of a concrete pipe
IPC: B28B21/34
Filed: 1972-04-06
Abstract: 1390989 Moulding cement pipes CONCRETE PIPE MACHINERY CO 6 April 1972 16024/72 Heading B5A [Also in Division E2] A concrete pipe is formed in a pipe form 10 (Fig. 1) by inserting into the pipe form a vibrating core 60, and continuing the vibration of the core after core insertion. As described for a first embodiment, a turntable 16 is rotated to bring a pipe form 10 beneath a concrete feed conveyer 28 and above a core 60. A packing head 30 is lowered and the core 60 raised by an hydraulic cylinder 38, the head and core interengaging adjacent the lower, bell end of the mould 10. Concrete is introduced from a hopper 26, while a pallet 22 is lifted a small amount, rotated and vibrated by legs 68 to form a bell end. (This mechanism is described in U.S. patent Specification 3,083,433). The packing head 30 is rotated in opposition to the pallet 22 which is then lowered, and the packing head 30 and core 60 raised through the pipe form while concrete is added (Fig. 3). The core is held against rotation by an attached block 50 engaging rods 48, and is vibrated by spaced, internal vibrators 62 turned on by a trip switch as the bell end is passed. As the packing head 30 reaches the pipe top, the head and core are lowered partway along, or to the bottom of, the pipe after a dwell period, and the process repeated several times while extra cement is added. Finally, the head 30 is stopped rotating, disengaged from the core, vibration stopped, and the core 60 withdrawn. The pipe form 10 includes circular corrugations, and the concrete has embedded reinforcing wires. The packer head 30 and core 60 can be raised from above by a crosshead. In a second embodiment the pallet 22 is omitted, and the bell end formed by vibrators 80 (Fig. 8) operated for a short time; the core 60 is then guided by rollers 82. For a third embodiment, the pipe is preformed in the pipe form 10, and the form and pipe are together placed over the core 60 for vibration. The vibrators 62 are supplemented by vibrators attached to the pipe form 10. Packing of the cement can be carried out by a rollerhead, trowel, vibration or tamping; the pipe may be spun. An interlock between the packing head 30 and core 60 is shown in Fig. 10 (not shown) (see Divisions E1-E2).
Patent GB-160661-A (GB)
IPC: A21C1/14
Abstract: 160,661. Tait, A., and Thomson, Ltd., D. March 15, 1920. Interconnecting protector with starting-gear.- In a dough or like mixing-machine, the starting- gear is connected with the cover fastening in such manner that the cover is locked while the machine is running and the machine cannot be started until the cover is closed. The sleeve e of the clutch for connecting the pulleys to the shaft g has keys f engaging the shaft g and carrying a grooved collar h. Trunnions on a pivoted lever l engage this collar, the upper end of the lever being formed as a cam surface with a central depression to engage a bowl on a lever n. The fore end of the lever n is connected to a crank-pin p on a plate q coupled to a grooved collar r mounted on a pin. An inclined slot t in the collar r engages a fixed pin, so that rotary move. ment of the plate q, due to the action of the cam surfaces on the lever when operated, is converted into a longitudinal movement of the collar r which serves to move a locking-lever s, the end of which is adapted to engage a notch or slot in the catch w of the mixing-chamber cover. When the cover is open, a spring plunger x prevents the movement of the lever s into engagement with the catch and consequently prevents the movement of the clutch to start the machine. Upon closing the cover, the plunger x is forced back, and the lever s enters the slot and locks the cover in the closed position when the clutch is operated.

A copying lathe or like machine tool has first and second supporting means for a templet to hold it with its axis generally parallel to the lathe axis, in which the first support, at the headstock end of the lathe, is thermally insulated from the machine base and is displaceable relative to the headstock to compensate for expansion and maintain the axis of the templet in parallelism with the spindle axis. The pattern 12, Fig. 1, is adjustably carried by arms 14 pivotally supported from a bar 15. The latter is mounted parallel to the workpiece in supports 13 and 29, Fig. 4, at the headstock and tailstock ends respectively, of the machine. The first support 13 may be secured at 18, Fig. 1, by its lower end, to the headstock frame with an air gap 17 for thermal insulation. An adjustable tie-bar 19 connects the upper end of this support to a point 20 forward of the spindle axis which is chosen so that heating up of the headstock and tie-bar compensates the changes in distance which would occur between the pattern 12 and workpiece with the support directly attached to the frame. In a modification, the support 13 is pivoted to the frame and a tie-bar passes underneath the spindle to the front of the machine. Compensation for temperature changes in the second support 29 may also be provided for. The support 29, Fig. 4, is then pivoted at 30 and a tie-bar 31 secured to the support is brought through the bed to an adjustable anchor 33 in front of the tailstock.
