Abstract
775,821. Angular bending. MINGORI, R. P. April 5, 1955 [April 7, 1954], No. 9995/55. Class 83 (4). A portable tube-bending machine of the type including a pressing pad 55 movable towards and between two tube-engaging rollers 43 is characterized in that the pressing pad 55 is carried by a screw-threaded rod 2, slidable but non-rotatable in a casing 1, the axial movement of the rod 2 being effected by means of a worm gear drive, including a worm wheel 4 rigid with a nut 3 in threaded engagement with the screw rod 2 and mounted for rotation, but not axial movement, in the casing 1, and a worm 5 in mesh with the worm wheel 4 and rotated by manually operated means, such as a handle 7 or ratchet lever 8. The rollers 43 are supported in holes 46 in upper and lower plates 42, 44, respectively, carried by loop members 39, 47 which hook over a head 33 secured to the casing 1. The upper plate 42 is slidable transversely in its carrier member 39. The lower plate 44 has secured thereto a plate 51 which rests against an abutment on the head 33. Two telescopic legs 57 are pivoted to the lower plate 44 and one is screwed into the casing 1.
