JACOB N. SPANABEL AND LYMAN P. JUSTISON, OF EAST PALESTINE, OHIO.

FEED-WATER REGULATOR.

Specification of Letters Patent.

Patented Sept. 19, 1905.

To all whom, it 777/6Ly concern:

Be it known that we, J AOOB N. SPANABEL and LYMAN P. J USTISON, citizens of the United States of America, residing at East Palestine, in the county of Oolumbiana and State of Ohio, have invented certain new and useful Improvements in Feed-Water Regulators, of'which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in feed-water regulators, and has for its object to provide a device which can be readily attached to a boiler to govern and regulate the quantity of water to be fed to the boiler.

Another object of our invention is to provide a device which while particularly adapted for controlling the inlet of water to the boiler is capable of designating the quantity of water within theboiler; and to this end we have provided novel means in connection with our improved device for adjusting the regulating and governing features of our improved device.

The device aims to govern the amount of water admitted to the boiler and to regulate the same, whereby an excess of water will be prevented from entering the boiler, and consequently reducing to a minimum the consumption of fuel in respect to the quantity of water being heated. The device also reduces to a minimum the quantity of water necessary to operate a boiler, and increases the steamgenerating power of the boiler, owing to the fact that no excess amount of water is permitted to accumulate Within the boiler.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts, which will be hereinafter more fully described, and then specifically pointed out in the claim, and, referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a front elevation ofour improved device as connected to a boiler. Fig. 2 is a side elevation of a portion of the device used for controlling the water-inlet of a boiler. Fig. 3 is a detail view of a flexible joint used in connection with our improved device; and Fig. 4c is a side elevation view, partly in section, of an adjustment construction used in connection with our improved device.

To put our invention into "practice and to demonstrate the use of our improved device in connection with a boiler, we have illustrated diagrammatically the front end of a boiler, which is designated by the referencenumeral 1, and the front or the housing of the boiler is designated by the reference-numeral 2. Adjacent to the boiler we mount a framework 3, having a platform 4:, and in said frame is mounted a tank 5, the framework serving as vertical guidewaysfor the tank 5.

The framework and the tank are preferably mounted in horizontal alinement with the water-line 6 of the boiler 1, and the top of said tank is provided with a pipe 7 and the bottom of said tank is provided with a pipe 8, said pipes passing through the platform 4. and the top of the framework 3 and serving as guides for the tank 5. The tank 5 is supported upon the platform 4 by a coiled spring 9, which surrounds the pipe 8, and said coiled spring rests upon a plate 10, which is adjusted vertically by set-screws 11 11, carried by the platform 1. The tank 5 is provided with a waterglass 12, whereby the contents of the tank can be observed from the exterior thereof.

The reference-numeral 14 designates a water-inlet pipe, which is connected by a pipe 15 to the boiler 1, and the pipe 1 1 is provided with a valve 16, having a vertically-actuated valve-stem 17. The pipe 14 is provided with a split sleeve 18, carrying a standard 19, to which is pivotally connected, as indicated at 20, a lever 21. The lever 21 is connected to the vertically-actuated valve-stem 17, as indicated at 22, and the forward end of the lever 21 is adjustably secured between two nuts 23 upon a screw-threaded stem 2 1. The screwthreaded stem 24: is supported by a T connection 25, carried by the pipe 7 of the tank 5. Upon the opposite side of the boiler is mounted the ordinary type of Water-gage 26,

which is connected by a pipe 27 to the T connection 25, and also by a pipe 28 to the swiveled joint 29. An auxiliary pipe 30 connects the pipe 28 with the boiler 1. A pipe 31 connects the pipe 8 with the swiveled connection 29.

The operation of our improved feed-Water regulator is as follows: Water is admitted to the boiler 1 through the pipe 14, valve 16, and pipe 15, and as the water enters the boiler 1 and rises therein it simultaneously rises in the tank 5 and the water-gage 26, on account of said tank and water-gage being connected with the boiler by

pipes

8, 31, 28, 30, and 27, and the height of the water within the boiler can be observed from the water-gage 26, also from the water-glass 12, carried by the tank 5. The capacity of the tank 5 is made such that when the water accumulates within the tank the weight of the same will lower the tank 5, and through the medium of the screwstem 2 L, lever 21, and valve 16 the flow of water through the pipe 14 to the boiler will be regulated. The receding movement of the tank 5 compresses the spring 9, and upon the water again assuming its level the spring expands and raises the tank 5. The tension of the spring beneath the tank 5 can be regulated by the set-screws 11 11, carried by the platform 4:. The operation of the valve 16 can be adjusted by the nuts 23 28, carried by the screw-threaded stem 24:.

a On account of the vertical movement of the tank 5 we have found it necessary to employ a swiveledconnection 29 to permit of the pipe 8 being moved without distorting or moving the stationary connections of our improved device, and the swiveled connection 29 can be readily employed in connection with the other pipes where one pipe moves in relation to another pipe.

From the foregoing description,.taken in connection with the drawings, it Will be observed that the quantity of water fed to the boiler can be readily controlled by our improved regulator, and while we have herein illustrated the same as being mounted upon the front of the boiler it can be readily secured to a suitable support located in the vicinity of the boiler, and it is always essential that it be elevated at a height corresponding to the water-line of the boiler.

It is obvious that various other changes may be made in the details of construction without departing from the general spirit and scope of the invention.

What we claim, and desire to secure by Let ters Patent, is-

In a device of the type described, the combination with a boiler, a frame mounted adjacent to the boiler, a tank movably mounted in said frame, a spring arranged below said tank, means carried by said frame below said spring to regulate the resiliency of the spring, an inlet-pipe leading from the boiler to said tank, an outlet-pipe leading from said tank to the boiler, a supply-pipe leading to the boiler, a valve arranged on said supply-pipe, a pivoted lever attached to said supply-pipe and adjustably connected to said tank, substantially as described.

In testimony whereof we afiix our signatures in the presence of two witnesses.
