HENRY H. GORRIN AND AXEL O. TENGVALL, OF NEW YORK, N. Y.
HYDRAULIC EJECTOR.
SPECIFICATION forming part of Letters Patent No. 314,237, dated March 24, 1885.
Application led December 29, 1F84. (No model.) A
To @ZZV/hom it' may concern:
Be it known that we, HENRY H. GORETNGE and AXEL O. TENGVALL, both residing inthe city of New York. N. Y.. have invented an Improvement in High-Pressure Hydraulic Ejectors; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
The object of our invention is to provide high-pressure hydraulic ejectors with asimple, reliable, self-adjusting attachment which will effectually prevent the pressure in the highpressure pipe from being communicated to the low-pressure pipe or create an excessive pressure in the discharge pipe or hose. We attain this object by the mechanism illustrated in the accompanying drawing, which represents a vertical section ofthe entire machine.
The passage A communicates with the highpressure pipe, the passage B with the lowpressure pipe, and the passage C with the discharge pipe or hose. Through the passage D the pressure existing in A is communicated to thesnialler piston E. Through a similar passage, F, the pressure in C is communicated to the larger piston G. By turning the handle H the cone-Valve I is opened and the ejector 3o put in opera-tion. The pressure on the piston E keeps the cone-valve open until the pressure `in C rises above the desired limit, when the pressure on the piston G will become greater than that on the piston E and the cone-valvev will begin to close, thus reducing theopening for high-pressure water, and decreasing the flow and consequently the pressure atG. The nut K is left free `to slide up and down in the guide-bracket L.
We are aware that hydraulic ejectors have been described, made,and used for many years,
and that self-adj usting devices for hydraulic ejectors have been patented.
What we claim as our invention, and desire to secure by Letters Patent, is-
A hydraulic ejector in which the pressures in the discharge-pipe and high-pressure pipe HENRY H. GORRINGE. AXEL O. TENGVALL.
