Abstract

437,267. Power hammers. DOWNIE, R. R., Beaver Falls, Pennsylvania, U.S.A. March 24, 1934, No. 9304. Convention date, March 27, 1933. [Classes 68 (i) and 68 (ii)] [See also Groups X and XXII] Means for breaking rocks, roads, &c., and driving piles &c. comprises a boom 12 pivoted to swing vertically and horizontally and a stick 13 pivoted to the outer end of the boom and carrying a heavy maul 20, secured by bolts 23 and braces 21 ; a lifting line 15 is connected through links 17 and arm 18 to the stick while a striking line 14 passes over an arm 30 on the stick and is secured to the latter. The maul has a removable head 24 secured by bolts 29 and centred by spigot and socket 24<a>; the rounded head shown may be replaced by one having a pick or axe edge. The maul may be replaced by a scoop to adapt the machine for ditching. Specification 231,055, [Class 68 (i)], is referred to.
