SPECIFICATION forming part of Letters Patent No. 750,909, dated February 2, 1904.
Application filed May 18, 1903. Serial No. 157,516. (No model.)
To aZZ whom it may concern:
Be it known that 1, JAMES WVALLAoE TALL- MAN, a citizen of Canada, residing at Beamsville, in the county'of Lincoln and Province of Ontario, Canada, have invented new and useful Improvements in Steam-Boilers, of which the following is a specification.
My invention relates to improvements in marine and portable steam-engine boilers in which a steam-valve chamber provided with an automatic steam-valve-regulating pendulum is connected to the upper and central part of a steam-boiler and steam-pipes connecting the said chamber with the upper and end parts of the boiler.
The objects of my invention are, first, to provide means for preventing steam-boilers of the marine and portable class of boilers from priming; second, to provide means for delivering dry steam from the boiler to theengine at Various steam-pressure and under all conditions and circumstances of the engine and boiler, and, third, to afford facilities for delivering steam from the highest part of theboiler to the engine under all conditions to which the boiler may be subjected while on the sea or in portable or inclined position on land. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a sectional elevation of a steamvalve chamber with automatic coacting valves and gravitation pendulum connected to said valves and steam-pipe connection with said valves and with the upper part of a boiler, the boiler and the said connecting-pipes being broken. Fig. 2 is a sectional plan of the same through the central part of the steam-valve chamber. Fig. 3 is a detail plan of the detached base part of the said chamber, showing recess for guiding and also for stopping the pendulum.
Similar letters refer to similar parts throughout the several views. Y
In the drawings, A represents the upper part of a steam-boiler of the marine or portable class.
The steam-valve chamber is indicated by 2, which has a base part 3 secured to the upper and central part of a steam-boiler A in approved manner.
The steam-valve chamber 2 has diametrically opposite horizontal steam-inlet branches 4, in which the coacting valves 5 are adapted to slide and operate therein. The steam elbowpipes 6 connect the branches 4 with the upper part of the boiler A at a suitable distance from the ends of the boiler, allowing free passage for the live steam from the boiler to the valves 5. A hollow column 7 is secured to the upper and central part of the chamber 2 in an approved manner, and a cap 8 is secured to the top of said column. The pendulum-rod 9 of the pendulum 10 is pivotally connected to a pin 12 through the upper part of the column 7 and is adapted to swing on said pin by the action of the boilerthat is, when the boiler is subjected to uneven sea, or unlevel land when the boiler is raised higher at one end than the other end thereof.
It is intended that the steam-pipes 6 shall extend almost to the end of the boiler, and preferably so, in order to take dry steam from the highest part of the boiler when the same is unlevel.
The pendulum-rod 9 is rigidly and suitably connected to the pendulum 10 and forms a part of the same. The valves 5 have certain lugs 14. One end of the connecting-rods 15 is pivotally connected to said lugs and the other end of the connecting-rods 15 is pivotally connected to the pendulum 10 by means of the pin 13, which extends through the pendulum.
16 is a suitable slot in the pendulum 10 to allow sufficient space or opening in the pendulum for the connecting-rods 15 to operate freely therein when the pendulum swings.
The two valves 5 are shown open to admit steam to the chamber 2 and in normal positionthat is, when the boiler A is level and the pendulum is always perpendicular, as shown, by the laws of gravitation.
For the drainage of condensed steam in the chamber 2 or possible water lifted from the boiler into said chamber a small opening 17 communicates with the lower part of said chamber and the steam-boiler for said drainage purposes. The lower part 3 of the chamber 2 has an oblong guide-recess 18, (shown in Fig. 3 of the drawings,) and the lower end of the pendulum 10 is provided with a guidewheel 19, which is adapted to revolve on the stud 20 of the pendulum. 21 is a nut or other retaining device on said stud 20 to retain said wheel 19 in position on the stud. The
\Vhen the right-hand end of the boiler A is raised by the action of the sea or the uneven land, as the case may be, the pendulum then swings toward the left-hand, consequently closing more or less the left-hand valve and opening more or less the right-hand valve, and when the reverse action of the boiler takes place the reverse action of the pendulum takes place. Consequently the valves are reversed. Both said valves coact in perfect unison together. When one said valve is affected, the opposite said valve is also affected, sosensitive are they to the motion of the pendulum.
In this invention dry steam will be delivered to the steam-engine under all conditions of the boiler when the same is level or otherwise. This is an important feature in the invention.
By the fact of the pendulum being hung from an eminence in or above the steam-valve chamber the valves in said chamber are more sensitive to the movement of the connected pendulum than they otherwise would be if the pendulum was hung in a position in proximity to the valves.
Various changes in the form, proportion, and minor details of this invention may be resorted to without departing from the spirit and scope thereof.
What I claim as my invention, and desire to secure by Letters Patent, is
1. In a steam-boiler, a valvechamber, steampipes connected to the opposite sides of the chamber and to the upper end parts of the boiler, valves in the chamber and opposite said pipes, a hollow column secured on the chamber, a pendulum hung inthe column and connected to the valves, and a steam-outlet in the column, substantially as set forth.
2. In a steam-boiler, a valve-chamber connected to the boiler, pipes connected to the opposite sides of the chamber and to the upper end parts of the boiler, valves in the chamber and opposite said pipes, a column secured on the chamber, a pendulum in the column and connected to said. valves and a water-outlet from the chamber into the boiler, substantially as set forth.
3. In a steam-boiler, a valve-chamber,steampipes connected toth Opposite sides of the chamber and to the boiler, valves in the chamber and opposite said pipes, a column secured on the chamber, a pendulum adapted to swing in the column and connected to the valves, and a pendulum-guide with stops in the chamber, substantially as set forth.
4. In asteamboiler,a steam-valve chamber, steam-pipes connected to the opp site sides of the chamber and to the boiler, valves, a pendulum swung in the chamber and connected,
to the valves, substantially as set forth.
5. In a steam-boiler, a steam-valve chamber, steam-pipes communicating with the opposite sides of said chamber and with the boiler, diametrically opposite steam valves in the chamber and means to operate saidvalves at the varying disposition of the boiler, substantially as set forth.
