Title: An attachment into drill machine for emery grinding and polishing
Inventor: FABER KAROL
IPC: B24B23/04
Filed: 1994-02-02
Abstract: An attachment is designed from a shaft (1), firmly countersunked in an axis of a cylindrical shape body (2) with a clamping mechanism (5) or without the abrasive paper clamping mechanism. On the whole surface of the body's peripheral area, elastic material (3) is fixed. When the attachment without the abrasive paper clamping mechanism is realised, the abrasive paper (4) is slided on elastic material and that abrasive paper is coupled to the lateral area of a cylinder. The coupling of the abrasive paper at the attachment during its rotation is realised by frictional forces between expanded elastic material and the abrasive paper. When the attachment with the clamping mechanism is realised, the fixing of the abrasive paper is solved so that ends of the paper, winded up at elastic material are fixed between fastening rods of the clamping mechanism, which are inserted into the hole (6) and the whole mechanism is fixed on the body (2).

IPC: B61F5/32
Filed: 1992-10-30
Abstract: A running gear for drop-frame rail vehicles includes a running-gear frame on which individual wheels are each rotatably mounted through a respective rocker and the rocker is fastened in an articulated manner and supported through primary springs. The connection of the running-gear frame to the carriage body of the drop-frame rail vehicle is provided through two articulated rods which are mounted on a crossmember of the running gear frame and which are fastened to the carriage body. The carriage body is supported on the running-gear frame through secondary springs which are mounted in pockets of the transverse ends of the crossmembers. Transverse stops which are disposed in the crossmember limit the transverse movement of the carriage body in relation to the running gear. Advantageously, the individual wheel and the drive of the individual wheel are mounted in the rocker in such a manner as to be connected to form a structural unit. This structure provides running gears for drop-frame rail vehicles in which the drop-frame nature of the carriage body is completely preserved and only wheel cases are present in the region of the individual wheels of the running gear.
