STEAM TRAE SBECIF'ICATION forming part of Letters Patent No. 661,372, dated November 6, 1900.
Application led July 26, 1900.
To (tu whom it may concern.:
Be it known that I, GEORG-E H'. GROTE, a citizen of the United States, and a resident of St. Louis, in the State of Missouri, have invented a new and Improved Steam-Trap, of which the following is a full, clear, and exact description.
This invention relates to improvements in steam-tra1' s; and the object is to provide a steam-trap with a simple means for regulating the tension-spring, whereby it is made unnecessary to shut off or take the trap apart in order to adjust the spring, thus resulting in a saving of time and consequent expense.
I will describe a steam-trap embodying my invention and then point out the novel features in the appended claim.
Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure is a sectional elevation of a trap embodying my invention.
The trap comprises a casing l, divided into upper and lower chambers 2 3 by a flexible diaphragm a. From the chamber 2 an outlet-pipe 5 extends, and this outlet is controlled by means of a needle-valve 6, adapted to engage in a valve-seat 7. The stem of this valve rests upon the diaphragm 4 and is normally held open by means of a spring 8, engaging at one end with a disk 9, attached to the lower end of the valve-stem, and at its opposite end engaging with a collar 10, surrounding the valve-casing 11, and on this ool lar lO is an arm 12, to which an adjusting screw-rod 13 is attached. This screw-rod 13 extends through the casing 1 and has on its outer end a hand-wheel 14. Obviously by turning this screw-rod the tension of the spring S may be regulated as desired, making it unnecessary to separate the parts for such adjustment.
In operation the waterof condensation en- Seria] No. 24,905. (No model.)
ters through the pipe 15 into the globe 15, where it is deflected bythe hemispherical plate 15b to the pipe 17, which has communication with the chamber 3, so that the pressure acting on the diaphragm et will close the valve against the counter-pressure of the spring. As the water lls it overiows through the pipe 16 and iows into the chamber2. As it rises in the pipe 16 to about one-half its height the pressure on the sides ofthe diaphragm 4L becomes equal, the shorter column in the pipe 1G and the pressure of the spring balancing the pressure of the column of water in the pipe 17. An increase of the height of water in the pipe 1G causes a depression of the diaphragm and a conse quent opening of the valve 6, which allows the water to escape until it has fallen to a level of about the middle of the pipe 1(3,when the valve is again closed.
Having thus described my invention, I claim as new and desireto secure by Letters Patentl A steam-trap, comprising a easing, a flexible diaphragm in said casing, dividing it into upper and lower chambers, pipes leadinginto said chambers, a valve for controlling an out let from the upper chamber, the said valve resting on the diaphragm, a collar surrounding the valve-stem, a spring arranged between said eollar and a disk on the lower end of the Valve-stem, an arm extended from said collar, and a rod having screw-thread engagement in the casing and engaging with said arm, substantially as specified.
In testimony whereof I have signed my name to this specification in thefpresenee of two subscribing witnesses.
GEORGE Il. GROTE.
