The lathe borins tool holder is made with the desired off- \- .T;f^ ■ l-fe!:^. Taper hfifTal/Sfock ( C— L .J^--l— _4. 4g —log- -A Drill Socket for a Machine Lathe set, having a shank IJ^ in. by 11-16 in. High speed tools,J4 in. square, are held in the holder by two ^-in. setscrews. The entire length of the holder is 8J/2 in. The proportion of the holder may be changed so that much largeror smaller tools can be used. The tools are easily removedfor grinding and they may be adjusted to suit the variousdepth of holes with but little trouble. This tool holder hasa number of commendable features. It is very rigid anduses high speed steel tools that can be made economically,but little material being wasted. The drill socket is used for drilling holes on a lathe. The. Lathe Boring Tool Holder For High Speed Steel Tools Stem is turned to fit into the tail stock center. This holdsthe drill in perfect alinement and eliminates the troublecaused by the socket slipping from the tail stock center whenthe drill pushes through the work, as is the case with othersockets. The tail or arm of the drill socket is long enoughto rest on the tool carriage and it relieves the tail stock ofall torsional strain. This tool has been found very satisfac-tory and useful. It is made from l-)i in. material, the armbeing 31-32 in. in diameter. It has a No. 4 Morse taper andis 10 S-16 in. long. FOLDING HORSE FOR SHEETMETAL WORK A device used in the Dale Street shops of the Great North-ern which has been found very useful for jacket work in theerecting shop is a folding leg horse, a drawing of which ijshown below. The legs are of No. 10 gage sheet steel bentto form an angle, and hinged so that they can swing inward.
