MEANS FOR TURNING ON AND SHUTTlNG OFF GAS BY ELECTRICITY.

SPECIFICATION forming part of Letters Patent No. 331,221, dated November 24, 1885.

Application filed Juno 3, 1885. Serial No. 167,556. (No model.)

To aZZ whom it may concern.-

Be it known that I, LE ROY S. \VHITE, of Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Means for Turning On, Lighting, and Shutting Off Gas by Electricity, of which the following is a specification.

My invention relates more particularly to gas-burners having a closed case wherein are 1 contained a valve for controlling the flow of gas to the burner-tip, a magnet or magnets, and an armature actuated thereby to open the valve, and to close it or allow it to close. and to also operate the sparking devices, whereby an electric spark is produced for igniting the gas, and a lock or stop by which the valve is held open until such time as the valve and the armature are released from the look by energizing the said magnet or magnets.

An important object of my invention is to provide in a burner devices of the kind above described, so arranged and combined as to produce a very small and compact apparatus of such few parts and simple construction that it may be made at small cost, and will not be liable to become inoperative or get out of working order.

An essential feature of my invention consists in a novel combination of two electro magnets and an armature having its metal so disposed with relation to the poles of the two magnets that when one or other of the magnets operates to lift the armature the armature will in rising also be made to revolve or turn slightly in one or other direction, so as to bring it into engagement with or free it from a stop or lock, by which the armature will be held raised and the gas-valve open so long as the burner is used, and until it is desired to close the valve and extinguish the gas.

' The invention consists in novel combinations of parts,hereinafter described,and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical section of a burner embodying my invention. Figs. 2 and 3 are elevations,looking from opposite sides of the internal mech 'anism of the burner without the case. Fig. 4 is a horizontal section of such internal mechanism on the plane of the dotted line a; x,Fig. 5o 2. Fig. 5 is a horizontal section on the plane of the dotted liney 3/, Fig. 2. Fig.6 is a dia gram illustrating the magnets, a battery, and

a key or switch, and circuits through which the apparatus is operated and Figs. 7and 8 are detail Views, hereinafter described.

Similar letters of reference designate corresponding parts in all the figures.

The case here represented for inclosing the parts of the apparatus consists of a cylindrical body, A, a base portion, A, screwed or otherwise secured thereinto and threaded to receive a gas-pipe or nipple, B, and a neck or tip-socket, A", wherein is fitted a burner-tip,

a. Within the case is fitted an interior frame, 6 5 here shown as composed of a metallic top plate of iron, C, to which are secured three electro-magnet coils, D D E, and a bottom plate, C, of brass or other non-magnetic material, and through which project the fixed cores or bars on which the coils are wound, thereby forming the poles (1 cl 0 of the magnets. The two plates C C are here repre sented as having between them a post or column, C of insulating material and in which are inserted nuts or plugs c 0 0, connected in circuits, as hereinafter described.

As here represented, the top plate, C, has an upward central boss or projection,0*,which fits gas-tight in the tip-socket or neck, A and in which are side openings, 0 through which the gas may enter the said boss or projection.

A little red lead or other suitable material placed on the boss 0* will make it a tight fit in the tip-socket A and will, with the screws 8 5 13 1' hereinafter described, secure the whole internal mechanism in place within the case. The boss 0* forms a valve-seat, upon which closes a valve, 11, the stem 1) of which extends downward below the head C, and has secured 0 to it the armature F, arranged in sufficiently close proximity to the poles (Z d e to be attached thereby. The armature F may be screwed upon the rod or stem 1), which may have a lock-nut, I), for aiding in securing the 5 armature and providing for its adjustment on the rod or stem relatively to the magnet-poles. Vhen the armature F is lifted by the attraction of the magnets, it lifts the rod and valve 1) b, and allows gas to flow freely through the boss or projection 0* upward into the tipsocket A and it also actuates the sparking devices as I shall now describe.

Through a tube or sheath, f, inserted into the top of the body A of the case, extends a rod or wire, 9, which is fixed in the metallic nut or plug 0 and constitutes a fixed contactpiece. The wire or electrode r is surrounded in the tube orsheath by insulating material 1*. In the wall of the tip-socket A is fitted to slide vertically a rod or wire, g, the upper end of which is bent over, so as to lie across the contact-point g and constitute a movable contact, and the lower end of which is bent transversely, so as to project partly across the interior of the tip-socket A A. spring, bearing upon the bent part of the wire or rod 9', serves to draw it down and preserve contact between the parts 9 g. \Vhen the armature F and valve Z) are raised, the valve will strike against the bent end of the wire or rod 9 and lift its upper end suiiiciently to break its contact with the point 9 and produce sparking; but the parts are preferably so adjusted that the Valve will not act on the wire or rod to break the circuit and produce sparking until it nearly comes to the upper end of its movement. The rods or fixed cores upon which the coils of the magnet D D are wound are rigidly fixed in the metallic top plate, 0, of iron, and hence the two coils D D form, in effect, a horseshoe-magnet, the poles d d of which are presented below the bottom plate, 0. The rod or fixed core upon which the magnet-coil E is wound is also fixed in the metallic top plate, C, and this forms, in effect, and'is connected in circuit so as to form, a second magnet.

The arrangement of the circuit-wires with the magnets, battery, and key-board or switch will be readily understood from Fig. 6. G designates the battery, and H the key-board, having a key or switch, It, which may be shifted so as to bring it over either of two buttons, t" j. From one pole of the battery G a wire, It, leads to the switch lever or key it. From the button 1 the wire t" leads to a screw, 2', which is to be inserted through the side of the case-bodyA and into the metallic plug 0, and from the buttonj a wire, j, leads to a screw, 7", which is likewise inserted through the body A and into the metallic plug or nut 0. From the plug or nut c a wire, 71", leads to the magnet-coil D, the opposite end of which is connected by a wire, 1, with the magnetcoil D, from which a wire, i leads to the metallic plug or nut c. As before stated, the wire or electrode 1, which forms one of the contact-points, is inserted in the plug or nut 0 and when a current is passed to the plug or nut c" it passes through the wire or electrode 57, thence through the wire or electrode 9, and downward through the body of the burner and the gas-pipe B to the ground.

In Fig. 6 I have represented the plug 0 as connected by a wire, t, with the ground I; and this wire 1' represents the circuit from the plug or nut 0', through the electrodes 9 g, and through the body of the burner and gaspipe to the ground. From the plug or nut c a wire, j, extends to the magnet'coil E, and the opposite end of this coil is connected by a wire, f, with the case, and thence with the ground. The wirej' in Fig. 6 represents the circuit from the magnet-coil E through the body of the burner to the ground. The opposite pole of the battery G is connected by a wire, 7c, with the ground.

From Fig. 6 it will be understood that when the switch or key 71 is shifted onto the button i the current will pass through the parts It t z" c i to the magnet-coil D, thence to the magnet-coil D, thence through the plug or nut 0 and through the electrodes or contacts 9 g, to the body of the burner and to the ground. hen the switch-lever 71 is shifted onto the button 7', the currents will pass through the parts k j j j" c j to the magnet-coil E, and thence through the burner-body and gas-pipe t0 the ground.

The armature F is of peculiar construction, in that it has its metal so placed,or is so formed and arranged relatively to the poles (Z d c, that the electro'inagnets, when energized, serve by their attraction not only to raise the armature and open the valve Z), but also serve to slightly rotate thearmature and valve in one direction or the other. As here represented, the armature F has a raised portion or upward projection, Z, extending diametrically across itand diagonally between the poles (Z d, so that the raised projection Z will occupy the relation to the magnets represented in Fig. 5.

If the magnet-poles were directly above the center of the raised projection Z, they would have no effect to turn the armature; but inasmuch as they are on opposite sides thereof, and are also on opposite sides of the central stem or rod, b, on which the magnet is fixed, they tend to turn the armature as well. as to lift it. This turning movement of the armature, in connection with its rising-and-:thlling movement, I utilize to lock the armature in its raised position, with the valve Z) open, and to unlock the armature and permit it to fall and close the valve.

In the present example of my invention the armature has in its side a notch, m, which receives a hook, on, extending downward from the plate 0, and if the armature is slightly turned after being raised said hook will engage a small notch, a*, in the bottom of the armature, as seen in Fig. 2, and will hold the armature raised.

Supposing, now, that it is desired to open the valve and ignite the gas issuing from the burner-tip, I shift the switch or key It so as to send the current through the magnet-coils D D. The poles (Z d will then have opposite polarity, and, acting upon the armature F, will, by reason of the raised projection Z, thereon raise the armature and turn it in the direction of the arrow in Fig. 5, so as to bring its lower side, or the notch n, in engagement with the hook n, where the armature will be held with the valve b open. The valve 7) in rising will act upon the electrode or contact-piece g,and by separating it from the fixed contact 9 will produce sparking and ignite the gas.

When the gas is to be extinguished, the switch or key is operated so as to send a current through the magnetcoil E, which thereupon attracts the armature F, lifts it, and also turns it in an opposite direction to that indicated by the arrow in Fig. 5, so as to free it from the hook and permit it, when the current ceases,to fall to the position shown in Fig. 2 and close the valve. \Vhen the coil E is energized,the magnet-coils D I) will be also energized in a slight degree; but their polepieces cl drwill havethe same opposite polarity, both being north or both south, and they will not interfere materially with the turning of the armature by the magnet-coil E to unlock it.

The armature F may be constructed in any suitable way, so that its center of magnetism will occupy such relation to the poles that they will in attracting the magnet turn it as well as raise it. As here represented, the result is secured by upsetting-or deflecting the metal of the armature F upward, so as to form the projection Z,- but it might be secured by thickening the metal of the armature at this point, or by having upon its upper surface and adjacent to the poles at d upwardly-projecting studs or portions.

It will be seen that by my construction I enable an automatic electric gas-burner to be so constructed that it may be entirely inclosed within a case of very small size, and which has few and simple parts, and is therefore not liable to get out of order and become inoperative.

The arrangement of the electrode or contactpiece g within a tube or sheath, f, which eX- tends upward from the case of the burner, and in which the electrode or contact-piece is insulated, is very desirable, as it brings the point of attachment of the wire with the electrode or contact-piece g at a considerable distance from the burner, and reduces the size of and simplifies the devices which are on the exterior of the case. This arrangement of parts is much more desirable than a clamp encircling the tip-socket A close to the burnertip, and having asbestus or other non-conduct ing material placed between it and the tipsocket, as has heretofore been done.

The movable electrode or contact-piece 9 may slide in a hole or bore formed by drilling down into the wall of the neck or tip-socket A or by simply grooving the interior of the tip-socket; but I prefer to arrange the parts as here represented, and as best shown in Figs. 7 and 8,which represent, respectively, a vertical sect-ion of the upper part of the apparatus and a horizontal section on the plane of the dotted line 2 2, Fig. 1, both views being upon a larger scale than the other figures. In the inner wall of the neck A is formed a groove, 0, which receives the electrode or contactpiece 9, and a cup-shaped bushing, thimble, or sleeve, p, is inserted tightly into the end of the neck A and therein secured by solder, riveting,or otherwise. This bushing or sleeve closes the open front of the groove 0 and completes the slideway for the electrode g,thereby keeping it out of contact with the tip a, which is inserted into the cup-shaped bushing or sleeve 12. The bottom of the bushing 12 has an opening of proper size to permit the free passage of gas upward, and forms a seat or abutmentagainst which the upper end of the spring 9' bears.

Instead of having a circular armature, I

might employ an armature consisting of a bar of about the same shape as the projection Z, the poles of the i'nagnets being arranged in the same position relatively thereto that they now occupy relatively to the projection Z. In that case the notch m should be in the end of the bar and the hook 02 arranged to correspond thereto.
