Be it 'known that I, RICHARD A. HAYES,; of Elgin, in the county of Kane and State of "Illinois, have invented a new and Improved 'Electro Magnetic Boiler Feed Regulator, of

which the following isa specification-i Figure 1 is a plan; Fig.2 isa detail sec- -tio11al view of one of the magnets and armastares, takenon line aim, Figql'. Fig.3is a front 0 elevationon line w w,'Fig.1.' Fig. 4 is a detail View in section on line y y in Fig.1. Fig. 5; isa detail view of one of the insulators.

My invention relates toapparatusforregu- Y lating the supply of water fed to a boiler and it consists of a lever connected with a;

steam-supply valve of a boiler-feed'pump, or with a'valvein the water-supply pipe, and

I withf the armature of two seriesof electro ..1 nagnets, the said magnets being connected with a relay, which directs the current through 4 either series asmay be required.

' The inventionalso consists in the detailsof ,con'strnction andjarrangement which will be hereinafter more" fully described, and then .pointed out in the claims. f j V f Reterrin-gtothe drawing, Ais'a hollow me tallic cylinder, having at its lower end a socket, a, for "receiving the' upper end of a'glass themetallic cylinder. a

' O is; a metallic head', whichis recessed to cylinder, B, which is smaller-in diameter than receive the lower end of the glass cylinder B,

and is provided'with' a" central opening-for receiving the pipe-bj'that connects "it; with the lower. portion of the boiler. This head {is of suflicient size to receive the bolts 0, which pass through it, and into the lower" endof the cylinder A, and bindit and the glass 'cyl-inder to the saidcylinderAL J I D is a glass cylinder that is smaller than I the'cylinder B. Its lower end is placed in a' socket, d, on the upper head of the cylin- .derA.

' E is a metallie'capfitted to the upper end jof'the, glass tube D, and provided with a v flange,je,'for receiving the boltsf, which pass into the upper head of a the cylinder A." The f bolts 0 and f are divided, and-provided with su-lator-case.

insulators F, as shown in the enlarged sec- "tional View, Fig. 5.

The separated ends of the bolts are provided with heads 6 t" that are placed in the in- The head 13 rests upon an insulatingsubstance, j, supported by the bottom of the case, which surrounds the bolt, and prevents it from touching the case, and the head i rests against theupper head of the "insulator-case.

'By means of the insulator F, and the glass cylinders B and D, the metallic cylinder A is perfectly insulated.

The cap E is conneeted with the upper part of the boiler by the pipe g, and as there is an open passage from the said cap to the lower head 0, the pressure in the metallic and glass cylinders is the same as that of the boiler to which the apparatus is attached, and the water stands at the same level in the boiler, and in the said cylinders.

G is a float, made of metal, or other suitable material, that is placed in the cylinder B, and

is provided with a spindle, it, apart of which, between the floatGr and the wire 1, is madejof insulating material. This spindle extends upward through the'cylinder Ainto the glass cylinder D, and has upon its upper end a me- -tallic heador guide, It, that'fits the cylinder loosely,.and holds the spindle centrally-in th *cylinder D. 1 --Th e upper surface of the guide 70 may be made conical, so that it will not retain dirt or sediment. I

- A fine wire or chain, l, connects the cylinder A and 'the spindle h, and a binding-screw, m i's attached'to the cylinder A, for receiving the electrical conducting-wires n 0.

- His an adjustable rod that slides through a'stuffing-box in the top of the cap E, and p is a binding-screw that receives the wire q.-

I is a'relay-magnet connected with theba-ttery J by the wire 1', and with the bindingscrew of the metallic cylinder A by the wire a.

The battery J is connected with the cap E by the wire g. r The armature K of the relay magnet I swings on a pivot, s, between the posts Mo, and is connected by a wire, '0, with one of the poles of the battery L. The post t is connected by the wire 20 with the magnetvM, and the post at is connected'by the wire a with the magnet O.

The terminal wire of the magnet is.c.o.n.-..

nected by a wire, I), with the magnet P, whose terminal wire is connected with the battery L, y The terminal wire of the magnet M is connected by the wire 0 with the magnet Q, whose terminalwire is connected with the battery L. It will be seen that the magnets O P and the magnets M Q are arranged diagonally opposite. l l l R R are, respectively, the armatures of the magnets O P, and S S are the armatures the magnets M Q. 7

T is a lever fulcrumed at U, and connected by rods d with the armatures of the magnets- M O P Q. The rods (1 of the magnets M P are oppositely connected to the end of the short arm of the lever T, and the rods (11 of the mag-i nets 0 Q are connected to the long arm of the lever at a distance from thefulcrum equal to the length of the short arm.

The end of the long arm of the lever T is connected by a rod, V, with a balanced throt tle-valve, A, which, is placed in the steamsupply pipe of a steam-pump, or in the feed-l pipe that leads from thepump to the boiler. j

The long arm of the lever T issupported by a caster, e, and its motion is limited by the stops f f, which are slotted, and pro vided with screws for holding'themin any desired position. l a

B is ,a bell-magnet of any ordinary con-. struction, which is connected, by a wire, .g,

with the binding-serewm of the metallic cylinder A, and also with the battery 0 by the wire it, the battery being connected with -a point, i, by an insulating-wire, j.

The operation is as follows: a l

When water is at the required level in the boiler, the float G supports the spindle h, so that the guide 70 touches the rod H, complet ing the electrical circuit of the battery J, ex citing the relay-magnet I, so that its arma ture K is drawn toward it and into contact with the post at. a i 1 By this means a circuit is established through the magnets O P, and the long arm of the leverT is drawn toward the valve A, V

which is thereby nearly closed, and remains so as long as the current is unchanged and W q magnet, when the guide It strikes the wire 1', ,whichcontinues to sound until the proper the steam-pump is only normally active. When the water drops in the boiler the float G also falls, and the current through the wires 1 n q is broken, andthe spring-k draws the armature K from the port a and against the port t, thus breaking the battery-connection with the magnets O P and establishing a current through the magnets M Q. This draws the long arm of the lever T from the valve A,

opening the valve and admitting steamfco thefeed-pump, which works with increased rapidity until the required water-level is attained, when the guide is touches the rod H, completingthe arena through the wires ld'r ng, and the magnets O P, being again excited, move the lever T toward the valve A, closing it and diminishing the action of the pump, or

stopping it altogether.

Should the water drop below the prescribed level,'the guide 70 strikes the wire '11 and establishes a current through the bell-magnet B, which continues to sound the alarm as long as a low state of water exists, or until the electrical current is broken by the rising ofthe float, l g i l This device for giving an alarm may be constructed and used independently, if desired.

' The rods d, that connect the armatures with the lever T, are provided with turnbucklesm, for adjusting the relative position of the armatures. a V

The armatures R Rof the diagonally-opposite magnets are arranged so that as one of them approaches I the face' of its magnet it brings the other armature within the influence of its magnet.

The turn-buckles m" are so constructed that they permit a continued motion in the lever T afterone'of the armatures strikesits'magnet, in order to allow the diagonally-opposite magnet to draw its armature to its seat. This is efl'ected by threading one end of the turnbuckle and allowing the head of the rod 11 to rest in the other end.

The armatures S t S are arranged in the samemanner. f

I do not limit my. improvements to the ex actform herein described, as it may, in practice, be found that a single magnet connected with thelever T, and an opposing springer weight may serve to move the valve A, and wires may also be arranged so that the current willbe established'through thewater when it rises so as to touch the said wires, when the float may be dispensed withi The advantages claimed for the invention are, that itcontrols the action of the pump,

so that a constant water-level is maintai'ned in the boiler, and in case of a derangement of the float or its connections the magnets that open the steam-pump throttle-valve are made to operate byrthe circuit established by releasingof the relay-armature.

- If, all, the valve-operating magnets."should become inoperative and thelwater continues togo down, an alarm is given bythe bellthrottle or governorvalve of a steam-boiler feed-pump, or the water-supply'valve, as the names 3 electrical current is established or broken by the rise or fall of the said float, substantially as herein shown and described.

2. The float-chamber consisting of a central metallic section, A, the glass cylinders B D, cap E, head 0, and bolts 0 f, substantially as herein shown and described.

3. The float 0, having the spindle h and guide 1:, the float-chamber, having an insulated central metallic section, A, the metallic cap E, adjustable rod H, and the electrical conducting-wires Z n q, in combination, substantially as herein shown and described.

4. The relay I and battery J, in combination with the float and float;chamber, made as described, and the conducting-wires n q, substantially as herein set forth.

5. The relay 1, the oppositely-arranged magnets M Q and O P and theirconductingwires, the lever T, connecting-rod V, and throttle-valve A, combined and arranged substantially as herein shown and described.
