IMPROVEMENT IN' BOILERFEEDER ALARM-DEVICE.

The Schedule referred to in these Letters Patent and making pai-topf Einsame,

To all whom it may concern Be it known that we, JAMES WILLIAM EBERT and ELI4 C. MCGLOY, of Zanesville, in the county of Muskingum, and State of Ohio, have invented a new and improved Tater-Regulator vand Alarm; and we do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the 'art to make and use the same, .reference being had to the accompanying drawing, forming part of this specilication.

rlhe object of" this invention is to provide a simple and reliable apparatus to regulate the supply'of feedwater for steam-boilers, and to give an alarm when the water-supply fails, for any cause.

The invention comprises au arrangement of valves in the feedwater supply-pipe for the pump, connected witha float and levers inside the boiler, so as to open and close the-passage as required.

Also, in ff'connection with the said valves, another set of valves in the steam-pipe, leading to the whistle, which, when the valve-supply fails, will give the alarm, all as hereinafter more fully specified.

The drawing represent-s a Isectional elevation of our Aimproved apparatus.

In the drawingarepresents a water-chamber, open to the waterc c are balance-valves, connected to eachother by the male screw d' and the: female screw (l, by 'which .the distance from leach other may be accurately ad" justed.

f is a water-pipe, leading to the heater or forcepump. l

A is a steam-chamber, open to the steam-pipe BL C' G' are balance-valves, connected in the same manner as the valves in the water-chamber above described. l

F is a steam-pipe, leading to the whistle WV- 'l represents the top of a boiler or water-chamber, connected to Aa boiler.

This regulator may be connected directly to the boiler, with the floats, 86e., in the boiler, or. may be erected on an outside chamber,with the lloats, Sac., in the chamber, and said chamber'` so arranged as to have f'ree'water-communication with the boiler.

B is a strong stem, attached to the boiler orrchamber inside, to support the lever B,at the fulcrnm E.

F' is one ef the two floats.V (In this case, two iloats are represented, but the apparatus can be used with one.) These are twoA hollow globes, connected by a pipe, and from this connecting-pipe is the vertical pipe G, forming connection'with the lever D.

a water-tank standing His a valve at the top of pipe G,to permit the escape of rarefied air from the floats, through the perforated cap I. l

K is a solid adjustable ball or weight, to balance the float or floats when in operation, and to make them more sensitive to the rise and fall of the water.

L is the fork that sustains the lever and iloat or floats when the-boiler is without water. I

M is a rod that passesthronglrtlie boiler. or chamber, with a screw upon thenpper end of it, connecting with 'the balance-valve stem, at E'.

This rod is connected with lever D, so as Ato admit of' motion at the connection. l

N is a link, connectedat 9 9, by joints, to the rod M and the lever D.

These joints are to counteract the etectodthe vithe operator; for by turning the stern H', the rod M is raised or lowered by screwing on or oil at the junction E. v

To facilitate this operation, the top M' of' the cap of the steam-chamber'L is` made square, and a clutch, K', dropped over it.

ABy raising this clutch, so as to clear theA square, it

can be turned, thereby turning the rod H', so as to lengthen or shorten the rod M, at thev junction E',

'which regulates the flow of water, as may be desired.

The-operation is as follows: vAs represented in the drawing, the water is high enough in the boiler, and the balance-valves O C are closed, and the supply of water shut olf. If` the water gets lower, the oats F descend, causing the rod M to be elevated, and the balancewalves G C to be opened, when the water flows freely through b f to the forcepump or heater; the valves close again when the water is at the required height. In case the supply of water in the pipe b gives out, the floats will continue to descend .until the bottom' of the slot g, in the upper end .ofthe valve-stem al, comes in contact with the lower end h of the valve-'stem H', causing the balance steamvalves C' C' to rise, and let steam pass to the whistle,

and the whistle will continue to blow until water is supplied, so as to raise the floats.

Having thus described our intention,

We claim asl new, and desire to secure byrLetters 1. The combination of the balanced valves C C, wa- 4. The arrangement ofi the extension M of the ter-supply pipe b f, oats, and iloatflever, substantially steam-chest L', cap K', and rod H. all substantially as as specified. specified.
