HENRYMCG'ANN, OF CLEVELAND, HIO.
l team Paw/w No. 84,642, ma 'December 1, 186s.'
mrRovmvmNT IN AUTOMATIC Bomen-FEEDERS.
The Schedule referred to in these Letters Patent and making part: of the same.
To all whom it may concer/n.:
Be it known that I, HENRY MGGANN, of Cleveland, in the county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in a Device for Feeding Steam-Boilers; and I do hereby declare that the following is a full and complete description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Y Figure l is a side view o f the apparatus.
Figures 2 and 3, a modification of g. 1'.
Figure 4, a detached vertical section of fig. l.
Figure 5, a-side view of iig. 3.
Figure 6 will be referred to hereinafter.
Like letters of reference referto like parts in the diierent views presented. f
The nature of 'this invention relates to a device for supplying water to steam-boilers, so that the water therein shall remain, at all times, at or near the waterline. When it falls below said line, the device voperates, to supply the' deficiency, and shuts oi the waterwhen the proper amount has been supplied to the boiler, the apparatus being automatic in its operation.
In iig. 1, A represents a case or shell, in which is a pendulum-float, indicated byl the dotted lines B.
Said float is attached to a shaft, a, projected, through the side of the shell, (and in which it has its bearings,) into a supplementary shell or water-chamber; O.
To the end of said shaft is secured an arm, D, the lower end of which forms the segment of a circle,pro vided with teeth or cogs, b, the purpose of which will hereinafter be shown.
vE is a valve-seat, and of which F is the valve," in the upper side of which are cogs or teeth, in which the ,teeth of the segment referred to are'made to engage, as shown in fig. 4, and by which said'valve is operated reciprocally, as and for a purpose presently shown.
G is an induction-water pipe, and YH, the eductionpipe, leading from the chest C to the boiler.
The practical applicationaud operationof this apparatus are as follows, viz:
It is attached to the head of the boiler, or at any other convenient place, in 'the position shown in iig. 1,.
cover, made to t water-tight, thus enclosing the valvel in a water-compartment, thereby equalizing the pressure of the water on the valve, and which is conducted into the same through the pipe G, connected to the pump.
The valve is operated by means of the iioat, which, as the Water in theboiler descends, will also descend` with it, as indicated by the dotted lines B, thereby moving the arm D, which, being engaged in the valve,; will move it to the right, and bring the parts c inopen relation with the parts e in the valve-seat, as shown in fig. 4, thereby allowing the water to iiow from thel chest, through the valve and pipe H, to
-same when at the line of safety, thus automatically regulating the water in the boiler, so that it cannot descend below the lowest water-line. Hence all danger of collapse from a deciency of water is avoided.
`In a former patent granted to me for a similar device, the stop-cock which was employed in that appaf ratus, instead of a sliding valve, was not enclosed in a water-chest, as is the valve represented above, but was uncovered, the objection to which is that,.unless the plug of the cock were made to iit closely'tight, it would leak, and thus make a wet place about under it; also, in consequence of its beingfitted so tight, the plug would bind in the chamber of the cock, so that the iioat sometimes failed to operate it, and therebyvdestroy its eiiiciency; but, by the use of a valve, and enclosing itin a chest, as above described, this diiiiculty is avoided; or, if the stop-cock is used, instead of a valve, and enclosed, as shown in figs. 3 and 5, in a waterchest, I, the plug may be fitted loosely in the chamber, and thus be free to move by the float, and, though it 'may leak, the water cannot iiud its way to the outside ofthe chest, but is conveyed back into the cock thence to the boiler. p
Fig. 6 represents a modied form of the valve, and which consists of a circular valve, J, iitted to a corresponding seat, K, the valve nbeing provided with cogs or teeth, in which the segment-gear of the arm D is made to engage, so that the valve is opened and shut as the float rises or falls.
What I claim as my invention, and desire to secure by Letters Patent, i.
l. The combination of the slide-valve F with the arm. D, shaft a, float B, case A, and chest C, substantially as speciiied.
2. The supplementary chest O, in combination with the shell A, as set forth.
