ttiif tier atmi (title,
ISAAC N. WHI'ITEIISEY, OF .MOUNT VERNON, INDIANA.
The Schedule referred to in these Letters Patent and making part of the same.
I, ISAAC N. WHITTELSEY, of the city of Mount Vernon, county of Posey and State of Indiana, have invented certain Improvements in Lock-up Steam Safety Valves and Steam -Gauges, for preventing steam-boilers from exploding, of which the following is the specification.
My invention relates to the combination of a rotary steam-valve and steam-gauge in such a manner that the said rotary steam-valve shall be capable of letting oli` the surplus steam when it gets above the number of pounds locked at; and, also, ot'showing by the steamgauge how many pounds of steam to the squarench is in the boiler.
Figure l is the front view of the ,dial and hand of the steam-gauge, and the end ofthe rotary steamvalve, to which the hand is attached.
Figure 2 shows the rotary steam-valve closed in its easing, as it is when attached to the boiler; also, the rod, and its weight attached toit ou -t-he right-hand end.`
Figure 3 shows the weight-box, with one side olf, and attached to the boiler with the weight in jt.
Figure 4 shows the steam-valve as it is when attached to the boiler, with its double lock-covers.
Figure 5 shows a small rotary diaphragm or piston, which operates the safety-valve and index ofthe steamgauge, with 'one side off.
A is a hollow rotary steam-valve, whiclrlets oft" the surplus steam.
D is the frame to which the valve A is attached, and in which it should work steam-tight.
C is the dial of the steam-gauge, which vis fastened on the left-hand end ofthe casing of the valve A.
O is the index of the steam-gauge.
E E are the double lock-covers to the valve A.
F is the rod to which the weight G is attached, and must be firmly fastened on the right-hand end of the valve A. Y
H is the box that the rod F and weight G work in, and is shown in g. 3 withV one side off, which should be firmly attached to the inside ofthe boiler.
I is the casing, of the rotary steam-gauge.
K'is the abutment attached to the casing..
L is the revolving diaphragnror piston.
- YV is a small opening in the side of the steam-gauge K, to let in the steam.
N N show the boiler, to which the weight-box H is attached, in iig. 3, and also the lockvj-caps E E and the steam-valveAand its easing B B,in fig. 4, all of which should he strongr and substantially made', so that the force of the steam will not cause them to spring.
When the steam gets above what the valve is locked at, the valve A opens'and lets the surplus steam escape, then immediately closes againfsteam-tight, and the steam in the boiler cannot get a pound higher than what the valve is locked at, thereby ecctually preventingthe explosion of the boiler by the steam getting too high. s
I claim as my inventiou- The combination of the rotary steam-valve A, casing B, dial O, lock-caps E E, rod F, weight G, box H, casing I, abutment K, valve L, substantially as and for the purposes herein set forth.
ISAAC lN. VVHITTELSEY.
