Abstract

1419670 Grinding rails ELEKTRO-THERMIT GmbH 28 Dec 1973 [29 Dec 1972] 59963/73 Heading B3D A device for machining rails which have been built up by welding comprises a chassis 1 which is adjustably connected to a grinding unit 6 and is adapted to move the unit parallel to a rail 3, the grinding unit being guidable over a guide template 12 having a fixing arm 22 and adjusting means 15, 16 whereby it is adjustable horizontally and vertically, and the guide template having an arcuate portion corresponding to the profile of the rail and straight portions at the beginning and end of the arcuate portion. The chassis 1 is movable backwards and forwards along a track 2 on which the rail is also fixed. A plate 21 on the chassis is connected to the fixing arm 22 by the adjusting means in the form of screws 15, 16 and, if necessary, a packing piece 18, or alternatively, wedges, whereby the arm is adjustable vertically, horizontally and angularly in relation to the chassis. The guide template 12 is carried by the fixing arm and receives rollers 4 of the grinding unit 6 which has a grinding wheel 8 and is adjustable towards and away from the rail by movement of a support 7 driven by a chain 10 from a motor 9. The rollers are caused to travel along the guide template 12 by an adjusting device 5 driven by a motor 11 or manually.
