J. H. BLESSING. Combined Air and Check Valve.

@gg-we 2 UNITED STATES PATENT OFFICE.N v
JAMES H. BLESSING, OF ALBANY, NEW YORK, ASSIGNOR TO THE ALBANY STEAM TRAP COMPANY, OF SAME PLACE.
COMBINED AIR AND CHECK VALVE.
SPECIFICATION forming part ef Letters Patent No'. 241,597, dated May 17, 1881.
Application filed December 22,1879.
To all whom it may concern Be it known that I, JAMEs H. BLEssING, ot the city of Albany and State of New York, have invented a new and useful Improvement in Combined Air and Check Valves, of which the following is a full, true, and exact description, reference being hadto the accompanying drawings.
In the use of steam-coils for heating considro erable quantities of air are released in the pipes, which it is most desirable to expel from them in order to secure the proper operation of the heating apparatus. 1t is therefore very limportant to place at the end ot' the return or I5 elsewhere air-valves which may pass out such air fromsaid pipes, leaving the steam within. It is also very important that when the pressure within the pipes becomes reduced below that of the atmosphere the air without shall zo find no opportunity of returning. A checkvalve is ordinarily employed to prevent this return, but with this disadvantage: that the steam or air escaping past such check-valve when raised is very liable to cut its face and 2 5 prevent the proper seating of the valve.
The form of valve shown in my drawings is designed to pass out air gradually whenever the pressure is above that of the atmosphere,
`but to seat closely whenever the pressure in 3o the coils becomes lower than that of the atmosphere. To accomplish this my valve is providedwith two independentoperativeportions, which are, however', connected together, one of which is arranged to almost seat when the 3 5 valve is in a certain position, the other of which is arranged to seat the valve closely whenever the pressure within is below that of the atmosphere. y y
Figures l and 2 represent vertical sectional 4o views of my valve in its lower and upper positions.
Similar letters refer to similar parts in both figures.
The valve is connected to the coil or other space containing air by pipe l?. The escape to the atmosphere is by pipe R. The valve A is inclosed in valve-chamber B, and seats upon the central horizontal partition, C. The-upper end of said valve is guided by means of an 5o adjustable tube, D, the end or pin connected with said valve sliding freely within said tube. The valve itself consists of two cylindrical. sections suitably connected, the upper of which,
E, seats closely on the upper side of the par-V tition O. The lower one, F, is so arranged that it can enter the tubular opening in the partition C.
When in operation` the valve should be adjusted as in Fig. 2, so that when in its upper position, as there shown, an annular opening 6o is left between the valve F and the partition. The advantages of this arrangement will be readily understood. When the steam-pressure is on the valve, which is its ordinary condition of operation, it is in the position shown in Fig. 2 when the air escapes past it, as indicated by the arrows, all the wearing and cutting action of said air being expended upon the corners of the partition and the upper corners of the lower valve, F. The valve E being 7o .elevated out of the way of the outtlowin g currents is therefore not affected or cut by them. When, however, the valve seats as in Fig. l the upper or check portion of the valve E seats closely on the upper side of the partition, and bot-h partition and valve being unworu said seat is tight.
Of course this valve can be used with an independent expansion-valve, il' desired, or it may be used in the manner shown, which al- 8o lows of a little leak or escape whenever the pressure within the pipes is above that of the atmosphere, but-closes tightly when such pressure becomes reduced below that of the atmosphere. 8 5
By means of the adjustment D the leal; can be varied to any desired extent, and any wear -or cutting upon the valve F can be readily compensated for by allowing the valve to enter farther in theannular opening of parti- 9o tion G.
Whatl claim as my invention, and desire to secure vby Letters Patent, is
1. A compound air-valve composed of two independent disks permanently connected together, one of which operates as a tightly-closing check-valve and the other as an air-escape valve, substantially as described.
2. A compound air-valve composed of two valve-disks and a connecting-stem, one otwhich roo acts as a tightly-closing check-valve against a, permanent seat and the other as an air-escape valve, the position of' said .escape-valve with reference to its seat bein g adjustable by means 5 of a screw, substantially :Ls described.
3. A compound air-valve which consists of two disks, E and F, connected by a. stem7 the valve Esei'vingas a pernmncntand tigbtcheck,
the valve F as an air-escape, sa-id valve F being adjustable with reference to its seat by 1o means of a, screw, D, substantial] y as described.
