Specification of Letters Patent.
Patented Mar. 23, 1920.
Application filed March 18, 1919. Serial No. 283,329.
To all whom it may concern:
Be it known that 1, JAMES lt. 'llennnunn, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Traps, of which the following is a specification.
This invention relates to heating systems, and more especially to radiators; and the object of the same is to produce a trap adapted to be attached to a radiator so that the water of condensation therein will. be automatically discharged when it reaches a certain volume.
Another object oi the invention is to provide means whereby the point of discharge may be regulated from the exterior of the trap.
Details of construction are set forth in the following specification and claim, and attention is drawn to the drawings, where- Figure 1 is a vertical section through this trap complete and 2 is a horizontal sectional detail on the line 2-2 of llig. 1.
In the drawings the numeral 1 designotes a casing preferably having a removable top 2 with an opening 3 to which may be attached in any suitable manner a vent cook or relief valve and the wall of the casing provided near its top with. an inlet opening 4: for the water of condensation. Through the bottom of the casing is an opening in which is screwed an annular nut 5 having a valve seat 6 within the upper end of its bore and a spider 7 in the lower end. Secured to the bottom of the casing is an outlet box 8 having an outlet opening 9. By making this box removable and the cover 2 removable, access to the interior of the casing and the parts carried thereby is rendered easy.
"Within the casing is disposed a rather heavy float 10 which is hollow and contains air. A pin 11 is screwed as at 12into the upper end of this float and drives it through a guide 13 at the midlength of the bar 1-1 carried within the casing, the upper end of this pin by preference being movably mounted within thh vent 3. Screwed as at 15 into the lower end of the float is a conical valve 16 adapted to rest upon the seat 6, and at the lower end of the valve is a pin 17 which. slides within and is guided by the spider 7. In the normal position of this float seen in Fig. 1, the valve is closed so that there is no outlet'tor liquid at the bottom 01: the casing. When the lloat rises the pin 11 is guided through the bar 14: the point 13 and the valve 16 comes off the seat 6 so that there is an outlet for liquid through the annular element 5 and the spider I into the box 2. 'llransversely through. the box extends a rock shaft 20 mounted. in suitable bearings 21 inthe side walls at the boat and containing within the latter a linger 27 underlying the pin 17. To the outer end of this shaft is secured a lever 22 projecting in a direction opposite to the finger 27' as seen in 2, and on said lever mounted a weight L3 which is rendered adjustable by means of a set screw 2 1. l t is essential (that this weight shall be less than the weight oil? the float 10, or in other words the float l0 and the parts carried thereby bearing on the finger 27 must overbalance the weight 23, no matter what the adjusted position thereof.
hen now this device is coupled up to a radiator at the inlet point 1-, assuming that the radiator is the heating unit of a steam system, water of condensation flows in at 1 and rises within the casing 1 until it eventually lifts the float. Now the water flows through the annular element 5 and past the valve 6 into the box 8 and out at 9. Each time the float rises the casing is relieved of the accumulated water, and it immediately drops back so that the valve 16 is again closed. Should steam flow in at the point 4:, it may escape out the vent 3 and it has no ellect on the float. llhe outlet is to a suitable receptacle, or may be coupled. up to waste, or in fact might be closed and the overflow water allowed to accumulate within the box 8 and be withdrawn from time to time. This detail is not essential. of the radiator is maintained at such term perature that there is little or no condensation, it flows in through the inlet a and will not raise the float. It is quite possible however, to have the pin 11 substantially close the vent 3 so that there is no appreciable outlet, and I reserve the widest latitude in this respect. Manifestly the adjustment of the weight .23 upon the lever 22 will increase or decrease the lifting tendency of the linger 27 and will therefore advance or retard the moment when the valve 16 will open under the influence of the water rising within the casing 1 around the float 10.
"When the steam gain access to the interior for Therefore the operator has means on the exterior of the device for adjusting the point at which it shall act. I11 addition he can at any time depress the outer end of the lever 22 and cause the forcible rise of the float 10 and discharge of what water has accumulated within the casing; and of. course he can at any time disconnect the device to purpose of cleansingor repair.
The foregoingdescription and the drawings have reference to what may be considered the preferred or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is y In a steam trap, the combination with a cylindrical casing having an opening at its bottom, a detachable cover having a vent opening, a bar across the interior of the was ing beneath the cover and having a guide beneath said vent opening, an annular element within the opening in the bottom of the casing, and a spider at the lower end of said element having a guide at its center, of a float movably mounted within said casing, a pin at its lower end projecting through the guide in the bar and loosely into said vent, a pin at its lower end propin on the float, a lever carried by the outer A end of said shaft and projecting in a direction opposite to that of the finger, and a weight adjustably mounted on said lever.
In testimony whereof I afiix my signature in presence of two witnesses.
