Abstract

1309166 Percussive tools A L SJOBERG 25 Aug 1970 [26 Aug 1969 19 Jan 1970] 40912/70 Heading B4C [Also in Division El] An implement comprises a hand cart having a substantially coplanar frame provided at its upper end with handles 4 and at its lower end with coaxial wheels 1, and an impact chisel 6 mounted on a driving apparatus 5 for the chisel, which apparatus is resiliently carried by the frame and controlled by control means connected with the handles. The apparatus 5 is resiliently supported on a slide by rubber rings 26, 28, and the slide is resiliently supported in the frame by springs 13 and is connected to a pedal 16 by a spring 15. The driving apparatus may be operated by compressed air, electricity or an explosive gas mixture. To facilitate withdrawal of the chisel 6 from the ground the frame may have at its lower end compressed airoperated pistons 40 for engaging members 7 of the slide. In a second embodiment, Fig. 4 (not shown), the driving apparatus is resiliently mounted on a slide by springs, and an additional guide for the chisel 6 extends from the bottom of the frame.
