Patented Mai. 22, 1932 JOHN M. HUGHES, OF CINCINNATI OHIO VALVE Application filed April 10,
The present invention relates to valves and more particularlyto multiple valves which, while susceptible of other uses, are particularly well adapted for use on locomotives for control of steam to the blowers at the valves or units in the locomotive cab for the control of steam to the blower and to the fire box. This is not only expensive practice, but also makes a great many joints which should be kept steam tight and also packing glands requiring attention from time to time.
It is one of the objects of the present invention to embody in a single unit, two valves operable by a single handle and with ports so arranged as to conveniently make connections with the steam pipe connnunicatins with the boiler and leading down in front or the rear boiler end, and to the blower pipe and induction pipe connected with the smokeconsumer. This latter pipe usually leads down from a point adjacent the upper rear left end of the boiler and branches to various jets or other outlets for introducing steam or steam and airover or relative to the fire bed.
Another object of the invention is to pro- 39 vide a multiple valve which makes necessary the opening of the valve port for delivery of steam to the the box, if the fireman desires an adequate supply or full capacity of steam to be delivered to the blower when the engine is shut off, in order to prevent the smoke and gases from trailing back over the train and coming into the cab. In practice it is found that firemen or engineers sometimes object to usingthe smoke consumer, due for instance to the attendant noise resulting from its use.
A further objectof the invention is to provide a multiple valve including a cut out valve element in the port for delivery of steam to the fire box, so that this valve element may be closed by an authorized person when the boiler is being inspected, without liability of scalding the boiler inspector should some one accidentally operate the main handle of the valve or if it should be desired to use the blower and positively prevent delivery of 1930. Serial No. 443,138.
steam to the fire box. This cutout valve is so arranged as a part of the valve unit that it requires no extra fitting and is constructed so that it cannot be readily operated by an unauthorized person without detection.
Other objects and advantages of the invention will appear in the following detailed description, taken in connection with the'accoinpanying drawings, forming a part of this specification and in which drawings:
Figure l is a view partly in central vertical section and partly in elevation showing amultiple valve constructed according to my invention, two of the valve discs being shown in seated position and the cut out valve being shown ooen.
Figure '2 is an elevation of the valve. Figure 3 is a'view similar to Figure 1 but showing another of the valves unseated.
Figure 4 is a similar view showing the two main valves unseated, and the cut out valve seated.
In the drawings, wherein similar characters refer to similar parts thruout the views, A designates the valve body including a globe portion B, oppositely disposed lateral eXten sions C and D projecting therefrom, and an extension E projecting downwardly from the globe portion; F, G and H valve discs; J means for'op-erating valve F; K a lost motion device connecting valves F and G whereby the latter will be opened only after the former has been opened to a predetermined extent and closed inadvance of the valve F; and L, means for operating valve H.
Extension C is provided with an inlet port 5; extension D with an outlet port 6, which may communicate with the blower, not shown in. the drawings; and extension E provided witha port 7 for communication with the smoke consuming apparatus, also not shown in the drawings. Between the ports 5 and 6 is a partition 8 provided with an opening 9 having an upwardly facing valve seat 10 for valve disc F and between ports 5 and 7 is a partition 11 having an upwardly facingvalve seat 12 for valve disc G, the seats 10 and 12 being oo-axial. In port 7 there is a partition 13 having a valve seat- 14 for the valve disc H, the latter valve being the cutout intended for use whenit is desired to positively prevent the 18, the lower end of the stem being v in Figure 4 cess. A pin the induction tube or smoke consuming apparatus.
Means J for operating the valve K may comprise a screw stem 16 having screw threaded engagement with a bonnet 17, as at provided with spaced flanges 19 and 20; and a hand wheel 21 at the'upper end of the screw stem 16. The bonnet 17 may be retained in place by a connecting nut 22 having screw threaded connection with the globe portion B in the usual manner. The upper end of the bonnet 17 may be provided with a packing nut 23, gland 24 and packing ring 25, all of which may be of conventional design. As suitable means for connecting the valve disc F torthe screwstem 16, the former may be prov1de d witha recess receiving the flange .19, this recess being open at the top and at the side as shown in Figures 1 and 4 in order that the valve disc may be slipped laterally into place withthe flange 19, accommodated in the re 31 extending transversely thru the screw stem has its ends received in recesses 32 thus causing the valve disc to rotate with the screw stem.
The lost motiondevice K in the example shown comprises a stem 33 provided with screw threads 34 at its lower end, an upper stop 35 carried by threads 34, a lower stop 36 carried by said threads, the stops 35 and 36 being separated a predetermined distance, and an expansion spring 37 bearing upon valve G and accommodated at its upper end in a recess 38 formed in the lower portion of valve F, the stem 33 extending thru a central opening 40 in valve disc G.- I
In Figure 1 both valves F and G are seated and it is to be observed that, upon rotation of the handwheel 21, valve F will be lifted from its seat 10 permitting steam to pass from port 5 thruopening 9 to port 6, as may be observed from Figure 3, but there is no motion transmitted to the valve G until the lower stop 36 engages the lower portion of valve D. Upon such engagement and further rotation of the hand wheel 21, the valve D, will belifted from its seat 12, as shown and then steam will also pass thru port? if valve H is unseated. In the example shown approximately a turn and a half of the hand wheel will unseat the valve Fto the extent shown in Figure 3, and further movement of the hand wheel with the viewof further opening the valve'will cause movement of valve G. Thus if the fireman desires full capacity steam to be delivered to the blower when the engine is shut oil, in
- order to prevent smoke and gases from trail:
ingback over the train and coming into the cab,.ehe must alsointroduce steam into the smokeconsumer or induction tube as previously mentioned.
the valve in such a way The valve H may be provided with a screw stem 40 having a key head 41, and has screw threaded engagement as at 42 with a bonnet 43 secured to the extension E as by connectof the screw stem 40, thus providing a recess 47 in which the head 41is disposed when the valve H is fully open. The packing nut 45 has screw threaded engagement with the bonnet 43 and compresses a packing ring 48 about the screw stem. The extension E may i 49 to receive a wire be provided with an eye 50 having a seal 51, the wire also being re ceived in'an eye 52 carried by the packing nut 45, the wire being looped thru these eyes 49 and 52 and the end portions embedded in seal 51. This serves as means to prevent tampering with the valve without detection.
When it is desired to inspect the boiler and ther-e is liability of scalding the boiler inspector in the event that hand wheel 21 is rotated to open the valves F and G, a suitable key, not shown in the drawings, may be used to close valve H, as shown in Figure 4 of the drawings which then prevents passage of steam to the fire box even tho valve G be open. (This valve H may also beused when makingvrepairs to the smoke consuming or in the event that there should apparatus in the induction tube and it is debe a leak sired to'use the blower during the trip to the engine house, where repairs are to be made.
It is to be observed that the'ports 5, 6'
and 7 extend from the globe portion B of that the pipe lead.- ing from the top of the boiler may be readily connected to the valve body, and the pipe leading to the blower may extend laterally from the valve and forwardly to the front of the locomotive. The usual induction tube may extend downwardly from the very bottom of the valve thus providing a compact and neat arrangement, doing away with a number of cab fittings now in common use.
. While I have herein disclosed specific means for operating valve F and a specific lost motion device between'the valves F and a G whereby the former is opened in advance of the latter, and the latter closed in advance ofthe former, it is to be understood that such is merely by way of example and changes may be made in detail without departing from, the spirit of the invention as claimed. 4
I claim: I
1; A multiple valve structure provided with an inlet port and twooutlet ports, a blower valve disposed to control communication between the inlet port and one of the outlet ports, an induction tube'valve disposed to control communication between the inlet port and the other of the outlet ports, a lost with an inlet port and two outlet ports, a
blower valve disposed to control communication between the inlet port and one of the outlet ports, an induction tube valve disposed to control communication between the inlet port and the other of the outlet ports, said valves disposed one above the other, a lost motion device operatively connecting the valves, and means below the lowermost valve for adjusting the amplitude of lost motion of the lost motion device whereby adjustment may be had as to the extent to which the blower valve is opened before the operating means becomes eifective relative to the induction tube valve.
