4Speciicr/rton of Letters Patent.

Patented Jan. 13, 1926.

Application' filed April 6, 1917. Serial No. 160.165.

-To, all 'whom it may concern.' I

lBe itknown` that I, JOSEPH F. BRIGHT- MAN, a citizen ofthe United States, and a resident of Syracuse, in the county ot- Onondaga and State of New York, have invented a certain new and useful Steam-Trap, lot` which the following is a specification.

This invention has for-its object a steaml trap which isv particularly simple in construction andhighly efiicient and durable in use in which-the container for `the water of condensation is stationary; and the' inven.

tion consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawimg's` in which like characters designate vcorresponding parts in all the views.

Figure l is a Vertical through the container.

Fig. 2 is a fragmentary sectional view taken on the plane at a right angle to Fig. 1. Fig. 3 is a sectional View taken online Fig. 4 is a diagrammatic view illustrating the steam trap as connected in a heating system. v This steam trap comprises generally, a

stationary container having an inlet and an outletvalves for controlling the inlet and the outlet, and means in the container for controlling the operation of the valves.

1. designates the container which includes a body open at its top and a cap 2. secured to-the bodyin any suitable manner as by bolts 3 extending through annular flanges on the body and the cap 2.

4 and 5 designate respectively, the inlet and the outlet for the container, the inlet being located in the cap 2 and the outlet in the bottom of the container, the inlet and outlet 4, 5 being preferably arranged in alinement.

'6 and 7 are valves for controlling the inlet 4 and outlet respectively, these valves being carried by cages 8 ,`9 threadinglr into the inlet V4 and outlet respectiveh. and

. formed with guides 10, 11 in which the stems 12, 13 of the. valves slide.

14 and A15 are springs located in the inlet 4 and the outlet 5 respectively, and arranged to normally hold the valves G and against the seats on the cages 8, 9.

The container is also formed with a pressure equaliai'ng passage'fgl noiially closed by avalve 17 carried byl the ,cage y18 and sectional view having a stein 19 in the cage, the valve being held in its closed position by a spring 20 encircling the stem and abutting against the guide 1S and the shoulder 21 on the stein.

The means for controlling the operation of the Valve operates to open thep'outlet valve 7 and the equalizing valve 17 which are nor-4 mally in .their closed positionalternately` with the inlet valve which is normally in its open position, said mechanism including gradually movable parts and connectei'es opeigated by said parts to have a'quiiil action after the gradually moving parts have been actuated a predetermined amount. The

gradually movable parts include a float 22 and connections operated by the float. These connections comprise a lever 23 pivoted at 24 between its ends to a bracket 25 depending from the cap 2, a rod 26 arranged in axial alineinent with the stems 12, 13 of the 'valvesf 6, 7 a toggle, one link of which is connetted to the rod, the other link of which is connected to the lever and spring normally tending to break the toggle and resist the nioyteipnentthereof which carries the toggle ioiil forward and into' the dead center line l-ietogglej The rod -26 is guided in suitable arms 27 carried by the 'bracket 25. The toggle is here shown as double in construetion and includes a double link. 28 pivoted at 29 to a block 30 on the lippe@ end of the rod 26. a double link 31 pivoted at 32 to the link 28 and a link b3 pivoted to the link 31 at 34 and to one arm of the lever '23, the other arm of which carries the oat 22.

Said connections further include springs 35 connecting the links 31 ofthe toggle. these springs 35 being connected to the.outer ends of the toggle links and normally -tending to hold the toggle out of its dead center line. that is. a line passing through the points a4. 32, se.

The equalizing part is operated by the rod 2Gthrough a lever 37 pivoted between its ends at 38 to a bracket 39, one arm of the lever having an adjusting screw 40 coacting with the end of the stem 19 ot the valve 17 andthe other arm thereof being pivoted at 41 to a collar 42 fixed to the rod-,26.

In operation, the inlet 4 is connected to a pipe :i543 which is the return pipe of a heating system including units as radiators 44 and the outlet 5 is connected b v a pipe 45 to the boiler 46. y

The equalizing passage 16 is connected by a pipe 47 to the upper part or steam dome f the boiler.

In operation, the outlet valve 9 and the equalizing valve 17 are closed while the valve 6 is open.- lVater of condensation or steam flows into the container, the steam condensing therein, and as the level of the water rises inthe container, the float 22 is carried upwardly gradually moving the lever 23, link 33,

toggle links

28 and 31 gradually tensioning the springs 35 as they pass into the dead center line from the upper side thereof, and as the joint 32 of the toggle passes to the opposite side of the dead center line from thatseen in Fig. l, the springs complete the opening of the toggley with a quick acticn' forcing the rod 26 downwardly so that the spring 14 will close the intake valve 6 and open the outlet valve 7 against the action of its spring.- Y

This movement also moves the'lever 37 to open the equalizing valve 17 so that the pressure within the trap is the same as that in the boiler hence permitting the water to flow into the boiler through the outlet 5 'and pipe 43.

As the oat falls due to the lowering o f the water. level, the toggle is gradually operated until its Joint 32 again passes the dead' center line whereupon the valves 7' and '17 are closed and the valve 6 opened with a quick action.

If desired,- a cut-out pipe494 may be prov vided connecting the return pipe 43 andthe water outlet 45.

The body 1- is provided with' a suitable blowout passage 50.

What' I claim is:

1. In a steam trap, the combinationof a container having alined inlet and outlet passages at its upper and. lower ends, valves controlling said passages has/ing stems extending toward each other,.actuating means for the valves comprisingan axially fmovable rod alined and coacting with the stems, a support located in.k the container adjacent the rod, and means carried bythe support and within the container for actuating the rod, said means comprising a iioat and mechanical connections between the float and the rod, substantially as and for the purs.,V pose described.

-2. In a steam trap, the combination of' a' container having alined inlet and outlet pas4 sages at' its upper and lower ends, valves for controlling the 'passages having stems, actu-` ating means for the valves Acomprising an axially movable' .rod alined and coacting .with the stems, toggle means 4having one of its. links pivoted between its ends to the rod, a spring connecting the toggle links, 'a float located in the container, a lever carrying the float, and connections between the lever and which is pivoted between its ends to the rod,

means connecting the other arm of the lever andthe other link of the toggle, a` spring connecting the toggle links and arranged to resist movement of the toggle -links into a straight line to move the toggle to effect a quick action of the toggle' when the joint thereof has passed the dead center line of the toggle, and springs tending to close said valves, substantially as and for thepur'- posespeciiied.

4.' A steam trap comprising a stationary *container having alined inlet and outlet openings at its upper and lowerends, an equaliz ing passage at its upper end, valves for controlling the inlet, outlet, and said passa e, actuating mechanism including an axia ly movable rod coactin with the alined valves to open one valve anclose the other, a lever ,pivoted within the container between its ends and having a float on one arm, a toggle, one link of which is pivoted between its ends to the rod, means connecting the other arm of the lever and the other link of the toggle, a spring connecting the toggle links and arrange to resist-movemento'f the toggle links into a dead center line to move the toggle to effect a quick action of the tog-4 gle when the joint thereof has passed the dead center line of the toggle, springs tending to close said valves, and -connections operated by the rod for opening the pres- ,sure equalizing valve, substantially as and for the purpose set forth.
