STEA -TRAP.

Specification of Letters Patent.

Application filed March 31, 1913. Serial No. 757,745

To all whom it mag concern I Be it known that I, ARTHUR BOOZER, of the city and county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Steam Traps; and I do'hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to be a full, clear, and exact description thereof.

The invention relates to steam traps and has for its object to simplify and improve the construction whereby the efficiency of the operation will be greatly increased.

To these ends the invention consists in the novel arrangement and combination of parts hereinafter described and more particularly set forth in the claims. 1

In describing the invention in detail reference will be made to the accompanying drawings, in which' Figure 1 is a central longitudinal sectional elevation of my novel form of steam trap, the valve operating mechanism being shown in full lines in the position which it occupies when the valve is closed and in dotted lines when the valve is open. Fig. 2 is aplan view in section on line 00-02, Fig. 1. Fig. 3 is a transverse section on an enlarged scale on line 3 1 Fig. 1.

Referring to the drawings, 1 represents an egg-shaped shell or casing which is provided upon the side adjacent'the bottom with a horizontally extending neck portion 1 and upon the opposite side adjacent the top with an inlet-pipe 2 through which the steam or water of condensation may enter the trap. The neck portion 1' is provided with a cover-plate 3 which is bolted to the.

casing aiid is provided with a screw-threaded opening 4 extending through the same. Mounted in the outer end of the opening '4 is an outlet-pipe 5 and screwed into the inner end of said opening is a rectangular hollow frame or support 6 having end walls .7 and 8, a partition wall 9 arranged between and parallel with said end walls and an externally threaded neck portion 10 formed integral with the end wall 8. The partition wall 9 divides the frame 6 into two compartments 11 and 12. The compartment 11 is open at the top and bottom and provided with a longitudinal slot 13 in each side, and the compartment 12 is closed at the top and bottom and provided with an opening 14 in each side.

Removably mounted in the neck portion 10 and extending through the same is a 'hollow conical valve-seat '15, and mounted to slide'in the walls 7 and 9 is a valve-stem 16 provided at each end with a conical valve 17 Said valve-stem 16 is also provided with a pin 18 extending radially through the central portion of the same and having the ends project through the slots 13 in the sides of the frame 6. Said pin 18 has a loose fit in the valve-stem 16 and is provided at each'end with a thumb-nut 19 for holding the same in position.

A pair of parallel arms 20 are pivoted at their lower ends upon a pin 21 secured in ears 22 upon the bottom of the frame 6 and have their upper endsjoined together by a pin 23. Said arms 20 are each provided with a longitudinalslot 24 through which the pin 18 extends. A float-lever 25 is provided at its free end with a hollow float 26 Patentedflct. 3, 1916. I

and is pivoted at the opposite end upon a pin 27 secured in ears28 upon the top of the frame 6, said pin 27 being arranged in vertical alinement and parallel with the pin 21. Said float-lever 25 is provided at its: pivoted end with a downwardlyextending lateral projection 29 which is provided" The parts are normally in the position shown in full lines in Fig. 1, with the valve 17 in closed position. As the water of condensation begins to rise in the casing 1 the float 26 likewise rises and. moves the float-lever 25 upon its pivot, thereby moving the projection 29 and the upper ends of the arms 20 to the left in Fig. 1. As the arms 20 are rocked to the left the pin 18 which engages the slots 24 will likewise be moved to the left in slots 13, thereby moving the valve-stem 16 to the left and opening the valve 17 When the water of condensation has passed out through the outlet-pipe 5 the float 26 will fall, thereby moving the projection 29, arms 20, and valve-stem 16 to the right and clos-' ing the valve 17 WVith the above construction it will be seen that the means for moving the valvestem engage said stem at its center and between its two supporting walls, and there is less liability of any cramping or bending of said valve-stem or uneven wearing of its bearings. It will likewise be seen that by re moving one'of the nuts 19 the pin 18 can be removed and the valve-stem 16 reversed so as to bring the other valve 17 in operative position with the valve-seat 15. It will also be seen that by locating the neck portion of the casing above the bottom of said casing and by closing the bottom and top of the compartment 12 there is less liability of any sediment entering said compartment and collecting upon the valve or valve-seat.

l Vhat I claim as my invention and de sire to secure by Letters Patent is:

1. An article of the character described comprising a suitable casing having an inlet and outlet, an outlet-valve seat, an outlet valve, a pivoted float-lever provided with a.

slot, a float connected to said float-lever, and an arm pivoted at one end to a fixed support and provided at its opposite end with means for engaging said slot, said outlet-valve be ing provided with a pin in pivotal engagement with said arm intermediate its ends.

2. An article of the character described comprising a suitable casing having an inlet and outlet, an outlet valve seat, an outlet valve having a stem slidably mounted, a pivoted float lever provided with a slot, a float connected to said float lever, and an arm pivoted at one end to a fixed support and provided at its opposite end with means for engaging said slot, said outlet-valve stem being provided midway its length with a pin in pivotal engagement with said arm intermediate its ends.

3. An article of the character described comprising a suitable casing having an inlet and outlet, an outlet valve seat, an outlet valve having a stem, a support for said valve stem, a float-lever pivotally mounted on said support and provided with a slot, two parallel arms pivoted at one end to a fixed support and joined together at the opposite end by a pin arranged to engage said slot, a longitudinal slot in each arm between the ends thereof, and a pin loosely mounted in the center of said valve-stem arranged to engage said longitudinal slots.

4. An article of the character described comprising a suitable casing having an inlet Copies of this patent may be obtained for five cents each. by addressing "Washington, D. C.
