Abstract

709,904. Road scarifiers. METROPOLITAN CONSTRUCTION CO., Ltd. Sept. 25, 1951 [July 24, 1950], No. 18462/50. Class 107. [Also in Group XXIII] An apparatus for roughening hard surfaces comprises one or more mechanical hammers with the bits directed downwardly mounted on a wheeled carriage having a manipulating handle, the handle extending a greater distance on one side of the wheel axis than the hammers are mounted on the other, the carriage being adapted to be rocked about the wheel axis, and the pressure of the hammers on the surface being controlled by an operator holding the handle. As shown, hammers 16-19 are mounted in staggered arrangement on a frame which may be vertically adjustable and laterally reciprocable within supports mounted on an axle 10 carrying wheels 9. A handle 15 is fitted to the supports on the opposite side of the axle to the hammers. The frame carrying the hammers may be reciprocated by means of a cam follower attached to the frame co-operating with a cam groove in the axle, Fig. 5 (not shown), or by a motor driven eccentric, Figs. 6 and 7 (not shown). The apparatus may be driven by a motor and the hammers may be of any known type, e.g. pneumatic hammers.
