Description: |
| Abstract:
Our invention relates to an improvement io in machine-tools-such as planers, shapers, cutters, slotters, and the like-the object being to increase the capacity of such machines by providing means whereby the shock usually given upon the reversal of travel of the table carrying the work is taken up, so that the return movement of the table can be made more quickly, and hence the machine be worked with greater rapidity than heretofore. The invention consists in one form in the use. in combination with the table or ram, of buffers or cushion-like devices which take up the first shock given on reversal of the bull wheel or gear in such a manner that the teeth of the wheel and rack or gear are engaged without the sudden jar heretofore felt. The buffer arrangement may, however, be applied to the moving part, whether it is the tool, the cutter, or the work.
Claim:
In machine-tools having a movable reversing table the combination with such table of a rack movable therein a crosshead carried by the rack, rods carried by the crosshead and springs adapted to be compressed by the rods on the first movement of reversal of the table before the latter is started. |
