FRrtz, a vided with piston rods moving cross subject of the King of Sweden, who have heads 8 along guides 9 on the frame 3 declared my intention to become a citizen holding the bearings or journal boxes 3. S5 of the United States, residing at Portland, From said cross-heads extend connecting in the county of Multnomah and State of rods 10, by which cranks 11 of the engine Oregon, have invented a new and useful shaft 12 are operated. Said cranks are Draining Apparatus for Tunnels, &c., of arranged in opposite radial directions and which the following is a specification. the shaft is provided with an efficient fly 30 My invention relates to pumping ma wheel 13 for carrying the cranks over their chinery for the removal of water from tun highest and lowest points. The shaft, is nels, mines and ditches, especially while also provided at one end with a pulley 14 they are under construction. for the transmission of power to otherma The object is to provide a cheap, simple chinery (not shown). One spoke in the and economically operated apparatus for pulley is provided with a slot i5 (see Fig. 65 said purposes. 5), any part of which may be occupied by When a tunnel is being constructed there a crankpin 16 which is movably secured in is almost invariably the difficulty encoun a slot, 1, (see Fig. 4) in a radial arm 18 tered that springs or other water will flow fixed on a short pump shaft 19, which is 3C) into the tunnel or excavation and must be thus rotated by the pulley; said shaft is thus removed by pumping, for which steam or journaled in the bearing 4 of the frame part other engines are then employed. In my 4 and provided at its outer end with an experience, however, I have found that usu other radial arm 18, having a slot, 17 in ally some stream or creek of water can be which a pin 16 is adjustably secured so that 2 6 found not far from the work and utilized the length of the stroke of two pump rods as motive power to operate the pump, espe 20, 20 may thus be altered to suit the avail cially if a.special motor for utilizing a low able power of the engine.
