Specification of Letters Patent.
Patented Aug. 11, 1908.
Application filed. January 14;, 1908. Serial No. 410,784.
To all whom it may concern:
Be it known that we, RIoHARD EISEN- TRAUT and FRIEDRICH VIELER, residing at Dillingen-Saar, Germany, have invented certain new and useful Improvements in Steam- Traps; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same.
This invention relates to'improvements in automatic discharging devices for the well known kind of vacuum liquid collecting apparatus in which the collecting chamber is placed in communication during the filling period with the vacuum, and during the discharge period with the outside atmosphere, by means of suitable valves controlled by floats.
The invention consists in thespecial construction of the device and in the method of working due to the same, as set forth in the claims.
The device according to this invention is illustrated in the accompanying drawing in Figure 1 in a longitudinal section and in Fig. 2 in plan with the cover removed.
The discharging device is connected to the means producing the vacuum by the branch a provided with a check valve 1) which opens inwards the said device being first exhausted. Owing to the pressure of the atmospheric air the air-valve c and the liquid discharge valve (Z are closed. The liquid can then enter from the vacuum conduit through the valve 6 into the collector vessel f which is provided with two floats g is. As soon as the vessel f is filled to such an extent that the small float is raised, the locking lever h which held fast the lever i, is displaced and thus the float 7c is disengaged. The bottom float, therefore quickly rises and operates the bell crank lever .7; causing it to take up a position in which the inlet valve 5 which was hitherto locked, is released and closed by the action of the spring Z. The spring 1 is arranged around the valve-stem, between the valve I) and a stationary abutment, and the valvestem has a yoke m for engaging with the short arm of the bell-crank lever 'i. During further upward movement, the spindle of the float k which passes freely through the float g strikes against a second bell crank lever. 0 by the movement of which the valve 0 is opened. Owing to the admission of air into the vessel f, the vacuum is destroyed and the liquid discharge valve d is opened, so that the vessel can be emptied. The upper float g is held by the locking lever h and the stop it in the highest position. WVhen the liquid sinks, the sinking float 7c releases the lever 0 and the valve 0 after which it brings the lever i back into the original position and opens the inlet valve b. At the same time the lever h fixes or locks the lever i so that the operation begins afresh.
What we claim is:
1. In a steam-trap, the combination, with a vessel for steam and water provided with an inlet-valve, an air-valve, and an automatic outlet-valve of a main float, a pivoted lever operatively connecting the said float with the said inlet-valve, a pivoted catch engaging with the said lever and normally holding open the said inlet-valve, a pivoted trip-lever connected with the said air-valve and operated by the said main-float, and an auxiliary-float arranged above the said mainfloat and operatively connected with the said catch.
2. In a steam-trap, the combination, with a vessel for steam and water provided with an inlet-valve, an air-valve, and an auto matic outlet-valve of a main-float provided with a stem, a pivoted bell-crank lever operatively connecting the said stem and inletvalve, a pivoted trip-lever connected with the said air-valve, and arranged in the path of the said stem, a pivoted catch engaging with one arm of the said bell-crank lever and normally holding open the said inlet-valve, and an auxiliary-float slidable on the said stem above the said ma'in float and operatively connected with the said catch.
In testimony whereof we affix our signatures, in presence of two witnesses.
