JAMES H. BLESSING, OFALBANY, NEW YORK.
SPECIFICATION formingpart. of Letters Patent No.283,064,dated"August 14, 1883.
Application filed March 11, 1882. (No model.)
To aZZ whom it may concern:
Be it known that I, JAMES H. BLESSING,
of the city of Albany and State of New York,
have invented a new and useful Improvement 5 in Steam-Pumps, of whichthe following is a full, true, and exact description, reference be ing had tothe accompanying drawings.
My improvement relates to an apparatus for I avoiding or diminishing the jar orconcussion" 1o occasioned by the operation of steam-pumps; and it consists in an apparatus by means of which the Inovementof the Wateris gradually started and stopped at each end of the-stroke. My invention will be fully understood from I 5 the accompanying drawings, illustrating in sectional elevation my improved pump, and in which A represents a steam-cylinder; B, a pumpcylinder, which may be provided with any 20 proper valves.
0 represents themain steam-piston, and L .the pump-piston. Interior to' the steam and pump pistons G L are the secondary steam and pump pistons E M. Theratio of the secondary 2 5 steam-piston E to the water-piston M is greater than the ratio of the main steam-piston G to the water-piston L. The main pistons are con nected by piston-rod D, andthe secondary pistons by secondary piston-rod E, which should i go make a reasonably-tight joint within the exterior piston-rod, and, if desired, might be packed.
/ The operation of my apparatus can now be understood. Supposing the main and aux- 5 iliary pistons to be at the right of their re- 9 spective cylinders, and steam to be admitted through the port N upon the right, this steam will tend to move both the piston E and the piston O tothe left; but therebeing less re- 0 sistance per square inch to the movement of the piston E, that pistonwill move first, and
will therefore startthe water in the pumpchamber by forcing out the water which is contained in the cylinder within the water-piston 5 L. As soon as the piston E has brought up against the main piston G the two pistons will move together to the leftuntil the tappet R of piston-rod F strikes the buffer H, when the piston E will cease to move, and the main piston C will complete its stroke. By thus stopping the piston E the flow of water is de creased, for two reasonsin the first place be cause only the area of the piston L is then acting to force the water out, and in the second place because the piston M, retiring into its cylinder, affords an additional space for the water in the left of the pump-chamber.
The piston 0 having completed its stroke to the left, steam is admitted through the port P This steam enters the interior steam-cylinder through the ports J, and the piston E is consequently the first to move to the right, thereby starting the water in the right of the pump-chamber, which water is in communication with the interior pump-cylinder by the ports K. The stroke is continued to the right 7 until the tappet S strikes against the buifer G,
and the main piston G has completed its stroke. Then the operation is reversed, as before.
What I claim as my invention, and desire to secure by Letters Patent, is s l. The combination of an exterior steampiston, open to the cylinder at its opposite ends and containing an interior piston, and an exterior water-piston, also open at the ends and containing an interior piston, whereby the interior steam and water pistons are operated before the movement of the exterior steam and water pistons, to gradually start and stop the movement of the water, substantially as described. V
2. The combination of the exterior piston, (1, open at both ends, the interior piston, E,
piston-rods D and F, the exterior water-piston, L, open at both ends, and the interior water-piston, M, substantially as described,
3. The combination of theexterior piston, 0, provided with ports J, the interior piston, E, piston-rods D and F, the exterior waterpiston, L, provided with ports K, the interior water-piston, M, and the buifers G and H, substantially as shown and described. JAMES BLESSING. Witnesses:
