Abstract

818,608. Cementing anchor bolts. GORANSSON. N. T. Oct. 4, 1957 [Oct. 15, 1956], No. 31108/57. Class 20(2) [Also in Group XXV] Apparatus for feeding cement-mortar into a bore-hole in rock &c., prior to the insertion thereinto of an anchor-bolt, comprises a cylinder 2 filled by removing a cap 3 and connected to a source of compressed air via a valve 4. The compressed air forces the mortar through a tube 5, containing a manually-actuated stirrer 6, to a flexible hose 8 extending into the bore-hole. In a modification, a piston pump feeds the mortar.
