APPLIOATION FILED MAR.31, 1900.

JAMES F. MCELROY, OF ALBANY, NEW YORK, ASSIGNOR TO GQNSOLI- DATED GAR-HEATING COMPANY, OF ALBANY, NEW YORK.
DYNAMIC TRAP OR DRAIN VALVE.
Specification of Letters Patent.
'ratented March 27, 1906.
To all whom it may concern.-
Be it known that I, JAMES F. MCELROY, a citizen of the United States of America, and a resident of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Dynamic Traps or Drain-Valves, of which the following is a Specification.
My invention relates to dynamic traps or drain-valves; and the object of my invention is to provide an automatic check-valve adapted for use in steam-heating apparatus, and especially applicable for use in couplings arranged to connect pipes carrying steam be tween railway-cars and so constructed that the water of condensation will be allowed to escape without the leakage of any appreciable amount of steam. I attain this object by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a top plan view. Fig. 2 is a bottom plan view; Fig. 3, a longitudinal section; Fig. 4, aside elevation; Fig. 5, an outline view of a pair of couplers, showing a trap in each.
Similar letters refer to similar parts throughout the several views.
For the purpose of permitti the Water of condensation to be readily exc uded from a pocket or lowest ortion of a steam-heating apparatus or om a steam-con ler, I arrange a metallic casting A, preferab y provided with a threaded portion a, adapted to enga c with threads in the steam pipe or coup er B and permitting the contents of-the steam pipe or coupler B to enter the casting A by means of suitable openings C. I also connect with the casting A a perforated nut D, the perforations E being arranged inthe head thereof, communicatingwith the interior of the casting A. The nut D is preferabl provided with a threaded flange d, whic meshes with threads on the interior of the casting A. I arrange a suitable gasket F in the nut D, adjacent to the flan e d, which may be secured in position by urring the lower edge of the flange d, as at d, as shown in Fig. 3, or in any other suitable manner, thus making a restricted opening in the nut steam is forced into the casting A through the openings C, preventing the discharge of steam from the casting A through the openings E. When steam ceases to enter the'casting A, the sphere G will by gravity remove from contact with the gasket F and allow an uninterrupted passage through the casting A and nut D and perforations E, which will allow water of condensation entering the casting A from the openings C to escape through the erforations E.
en I use my drain-valve on a steam hose-coupler, as shown in Fig. 5, I preferably arrange the same on the side thereof at the lowest ortion, which will allow the water to enter t e valve and to be discharged therefrom in the manner already described.
What I claim as my invention, and desire to secure by Letters Patent, is
1. In a drainage-valve, a casting provided with a chamberhaving its sides flaring outwardly at near one end forming aside pocket, with a passage-way at one end through which the fluid may enter the casting; a hollow nut provided with restricted openings adapted to e secured to the other end of said casting; a
s here placed in said chamber adapted to c ose the opening leading from said chamber to said nut when forced into position by fluid entering said casting'and when the pressure is removed, said sphere arranged to fall into said side pocket, substantially as described.
2. A drainage-valve consisting of a casting and a' sphere, said casting provided with a chamber of considerably -'larger diameter than said s here, said casting provided with interior walls flaring outwardly and forming a side ocket atone end of said chamber, said sp ere adapted to normally occupy said side pocket; a nut provided with restricted openings attached to one end of said casting; a gasket in said nut arranged to form a valveseat in said chamber for said sphere, said casting provided with an opening at the end thereof opposite said nut so arranged that said sphere cannot close said opening.
3. Ina drainage-valve a casting; a coupler; means for connecting said casting with said as compared with the interior of the casting A. coupler; a nut provided with restricted open- Within the casting A, I place a sphere G, adapted to engage with t e gasket F when ings adapted to engage one end of said casting; a gasket in said nut forming a valve-seat magma in said casting; a side pocket in said casting Signed b me at Albany, New York, this adjacefit to said nut; a sgherg in ssiilmi (lasting;1 29th day 0 March, 1900.
