IMPROVEMENT IN STEAM PUMPING-ENGINES.
Specification forming part of Letters Patent No. 134,212, dated December 21, 1872.
of the slide-valve and the seat and the parts connected therewith, as hereinafter set forth and described.
In the accompanying drawing, Figure 1 is a longitudinal section of the pump on theline mac of Fig. 2. Fig. 2 is a vertical cross-section of Fig. 3 taken on the line 3 y.' Fig. 3 is -a vertical section of Fig. 2 on the line 22. Fig.
4 is a detail, showing atop view of the valveseat.
\ Similar letters of reference indicate corresponding parts.
A is the pumping-cylinder. B is the steam- I engine. O is the piston-rod for both cylinders.
D is the steampiston.
E is the steam-chest. F is the tappet-rod, operated by the arm G on the piston-rod O. H is the slide-valve, and I is the valve-seat. Steam is admitted to the steam-chest through the pipe J. 'K K are steam-ports through the top of the valves. The
.valve is a box-valve, and is inverted over the seat, as represented in Fig. 1. It is moved on its seat so that the ports in the seat receive steam and exhaust it in a manner similar to the ordinary steam-engine. L is the exhaustport. M is a slide-valve, similar to the ordinary slide-valve of the steam-engine, placed on the end of the tappet-rod, the slotted'neck N of which valve strikes the lugs O O of the main valve, and moves that valve by positive motion, in case the main valve should fail to make a full stroke. It will thus be seen that the piston of the engine takes steam through the main valve. The main valve is actuated by steam admitted from the steam-chest by the slide-valve M through the ports S S. The
valve M is moved by the arm G of the pistonrod, which strikes the stops on the tappetrod F, which opens one of the ports S. This admits steam to one end of the main valve and opens the other ports S to the main exhaust. This takes place at every stroke of the engine, causing the main valve to pass back and forth over its ports. If this action should fail, or if the valve should stick, the lugs O O insure a positive action. P P are steam-orifices in the valve and seat at each end for cushioning the valve and preventing concussion. q q represent slots or grooves in the sides of the valveseat. q are holes in the sides of the valveseat, which open into the exhaust-port for permitting any steam to escape in case the valve should leak, so that it will not interfere with the proper working of the Valve. U U are ports from the steam-chest, which supply the valve- M with steam for the movement of the main valve. T is the exhaust-port of the valve M. The main valve, being inverted over the valveseat, and admitting steam through its top, is nearly balanced, and slides with but slight friction.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The box-valve H having lugs O O, and
