Abstract

1390491 Paving machine attachments ROBERT McGREGOR & SONS Ltd 13 June 1972 [16 June 1971] 28131/71 Heading E1G In an attachment for a concrete paving machine horizontal dowel rods 11 - e.g. for bridging the joints between slabs of unreinforced concrete - are taken one at a time from a magazine 10 and pressed through a guide 18 into the wet concrete, Fig. 2 (not shown) by forks 15 on a cross-piece 14 which is vertically reciprocated by an actuator 13. The forks 15 have concave ends corresponding to the dowel diameter selected. The magazine 10 comprises a pair of sloping rails 24 and a spring catch 17. The actuator may have a variable stroke and be electromagnetic, hydraulic or pneumatic. Alternatively the actuator 13 may comprise a mechanical drive incorporating means for vibrating the fork 15. An optional smoothing plate 26 is vibrated by an eccentric-weight motor 27. The attachment may be provided with further actuators for pressing in several dowel rods simultaneously and may be automatically controlled by the advance of the paving machine.
