VALVE.

SPECIFICATION forming part of Letters Patent No. 657,059, dated .August 28, 1900.

Original application tiled February 5,1900, Serial No. 4,046. Divided and thisl application filed March 19, 1900. Serial No. 9,275. (No model.)

T0 @ZZ whom 15m/[ty concern,.-

Beit known that I, ALBERT P. BROOMELL, residing at York, in the county of York and State of Pennsylvania, have invented, a new and useful Improvement in Valves, of which the following is a speciiication.

My invention is an improvement in valves, and while t-he valve is capable of a certain general application it is especially designed and adapted for use in connection with a steam-h eating system,as described in a former application for patent tiled by me February 5, 1000, Serial No. 4,046, and of which this is a divisional application. In the said steamhcating system it is desirable toopen a vent to the air when the steam is shut off from the radiator, and therefore the valve forming the subject of the present 'invention is adapted to vent to the atmosphere when it is adjusted to close or shut off the port leading to the supply.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is an end elevation, Fig. 2 a vertical longitudinalsection, Fig. 3 a top plan View, and Fig. 4 a horizontal section, of a valve embodying my invention.

The valve, as shown, comprises the casing having a head E', which is provided with a series of sockets E2 for the stop-pin and with an opening E3 for the valve-stem. Below and in line with the head E', I provide the valveseat, which is provided with the feed-ports 1, 2, 3, and 4 for the steam or other medium and with an air or venting port 5 for communication with the atmosphere. The casing is also provided with a nipple 6 for connection with the pipe leading from the source of supply and with a nipple 7, which connects with the radiator or other part to which the steam or other medium is to be supplied. Now in operation the steam or other medium flows into the valve through the nipple G and thence out through the nipple 7 when the valve proper is adjusted to feed steam or other medium to the radiator or other device.

The valve proper, N, is provided in its upper side with a non-circular socket O for the stem O. The valve N lits upon the seat E4 and is provided with the series of ports N', N2, N2, and N4, which may be turned to register, respectively, with the ports 1, 2, 3, and 4 when the valve is fully opened or to open any desired ones of the said ports 1, 2, 3, and 4 to any desired degree. vVhen the valve is in the position shown in Fig. 3, the ports 1, 2, 3, and 4 are closed and the' port N is in full register with the port 5, thus opening communication with the atmosphere and forming a vent from the radiator 0r other device with which the valve may be connected. In the case of the use of the device with a steamradiator this opening of the vent tothe atmosphere will break the vacuum and prevent a suction of water from the return-pipe of the system. This position of the valve is shown in Figs. 2 and 4. If now the valve be moved one point to the right, the port N4 will register with and open the feed-port 1, the airport 5 will be closed, and the steam or other medium will be fed through the port l to the radiator or other device to be supplied. Another step of the valve will open ports 1 and 2, and so on until the valve .is fully opened.

The stem O fits at its lower end in the socket O and extends upward through an opening O2 in the head-plate E', being provided beneath said plate with a packing portion or shoulder O3 and with a spring O4, bearing between the same and the Valve-plate and operating to'press the valve to its seat and the portion O3 tightly up against the head-plate E. On the stem above the head-plate I secure the arm P, having near its outer end the handle P', which has a limited longitudinal movement in the arm and has a stop-pin P2,

which can be set into any one of the sockets E2 to hold the valve in any desired adjustment. The outer end of t-he arm P is socketed and receives a screw P3, by which the handle can be locked in any one of the sockets E2, and a cross-pin EAl limits the upward movement of the handle and prevents its being pulled out of the arm P. By this means the valve may be readily adjusted to and heldin any of the positions before described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The valve herein described having a plu IOC) having sockets for the stop-pins,the valve-seatA having feed and air ports, the valve having' openings arranged for registration with said ports, the valve-stem extended through the1 casing and arranged to operatethe valve,"th'e valve arm, the handle l.carried by the ,a1-,m1 and a stop-pin carried by the handleandfar-l ranged to engage the sockets in the casing.

3. rlhe combination of the valve-casingfhavw v ing its head provided with a series of sockets for the stop-pins andwith an openingforthe, valve-stem, the yvalve-seat `having .feed and airports, the valve havin ga pluralityof ports arranged for registration with those V0f the valve-seat, the valve-stem having the ,pack-` ing portion or disk and movable longitudi-4 nally independently `v of the valve, :the spring between said lpacking portion andsaidfvalye, the valve-arm, and the handle and stop-.pin substantially as set forth.

4. The valve-casing having socketsgfor the stop-pin, the valve-arm, the handle movable longitudinally therein and having `'the stoppin to enter the sockets in the -casing,;and

means for limiting'themovement of the stoppin, substantially as set forth.

5. The combination of the valve-casing having the sockets for the stoppin, the valvearm, the handle movable longitudinally in ,the Said Yarm and having the stop-pin, the -screWl-for 'locking the handlev from endwise movement, and means for limiting the endwise movement of the handle, substantially 'as set forth.

`6. The combination of the Valve-Casin g hav- .inga series of feed-ports and a vent-port, and

the valve having a series of ports one of 4.Which registers'with Ithe vent-port when the .valve is closed and the ports of the valve being arranged for successive registration with those of the Seat, Substantially'as set forth.

7. The valve-seat having feed-ports, Vand anoutlet or exhaust port, and the valvefhavingports corresponding -in number with the feed-.ports of the-seatand ymovable into 'full register with the feed-ports in the feeding .positionof the valve and having oneof said l.valveports fmovable into Vregister with the exhaustjportwhen the valve is adjusted to close fthe :feed ports of the -valve seat, the

construction being such that all the feedportsare closedwhenthe exhaust-port is open.
