IMPROVEMENT IN vAPoR-BuRNERs.

Specication forming part of Letters Patent No. 105,240, dated September 18, 1877 application filed March 4, 1877. Y

To all whom it may concern.-

Be it known that I, HENRY WELLINGTON, of Brooklyn, E. D.,county of Kings and State of New York, have invented certain new and useful Improvements in Vapor-Burners, of which the following` is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 is an elevation of my improved burner, showing the several parts assembled for use, a portion of the shade being broken away to exhibit the location of the burner within. Fig. 2 is a perspective view, showing the nipple and lateral detached from the connected plate and packing-tube. Fig. 3 is an axial section of the burner, illustrating the several parts thereof in detail and the method `of applying the shade-holder.

Likeletters of reference in all the figures indicate corresponding parts.

My present invention consists in certain improvements upon the burner shown in my Patent No. 107,7 41, dated September 27,1870, and in a means of attaching a shade or reector to burners of a similar character, all of which will be first fully described, and then pointed out in the claims.

E is a curved deiector or plate serving to spread the ame, and having a socket, H, cast therewith. This socket receives the ordinary packing-tube A from below, and the nippleblock B from above, the two passing each other within the socket, as shown in the sectional view, Fig. 3.

Theplate C, which serves to form a passage within which the air and gas are mingled, is usually denominated the lateral.77 It is made separate from the plate E, and secured thereto by means of the projecting legs a a, entering corresponding openings b b cut in said plate E. It is essential that the lateral be very firmly secured to the deflector, for the reason that it operates to hold the nipple-block B, as hereinafter explained, and it is found that a simple battering down of the legs after they are inserted in the openings b b will notaccomplish the desired result in a satisfactory manner. I therefore twistthe legs a a, by use of a pair of pliers or other suitable means, giving them about a quarter-turn, more or less,

and then press them closely up against the under side of the delector, as plainly7 indicated at a, Fig. 1. By this simple expedient the lateral and deector are quite firmly attached.

The packing-tube A is crowded or jammed into thel lower end of the socket H, and occupies about the positionrindicated in Figs. 2 and 3. Around the upper end of the tubeA a chamber is formed for the reception of the lowermost portion ofthe nipple-block B, which, being drilled out, ts also over the upper end of said packing-tube. This nipple-block carries the screw-socket B., the needle-valve n, and the projecting nipple p, in which is the valve-seat, and it (the said block) is placed in its proper position, and there held by the nipple p, which bears against the under side Vof the projecting portion l ofthe lateral C. This method of holding the nipple-block in place is advantageous for several reasons. The joint or connection between the block and the other portions of the burner is very simple and easy to make. The bearing of the nipple under the lateral prevents the block from being blown out by too great a pressure of vgas within the burner when in operation. The joint between the nipple-block and its socket being smooth, the said block may be turned therein, and the jet of gas directed toward the proper point on the plate E, so that the iiame may produce its maximum results. This latter consideration is one of considerable importance in the manufacture of the burner, as

'little liable to damage or disarrangement of its parts; but should the valve or valve-seat become damaged by any accident, it is obvious that, by reason ot' the construction already described, the nipple-block can be readily replaced by a new one without the necessity of discarding the whole burner.

For the purpose of turningthe nipple-block in its seat it is perforated at its upper extremity, as shown in each of the figures, and ythrough this perforation a nail or other convenient implement may be inserted, forming a lever, by which the necessary adjustments may-be readily and easily made.

The valve-stein socket tt is screw-threaded throughout its length to properly receive and hold the screw-threaded stem of the needlepoint fn. It is important that some means be provided which will effectually prevent the needle-point from being crowded too tightly against its seat, thereby enlarging and otherwise damaging` the same. The head F is located upon the valve-stem insuch position that it shall abut against the end of the socket R when the valve u is properly located in its seat, and thus prevent said valve from being 'forced farther forward, which construction obviates the objection named in a very simple and thoroughly practical manner.

To connect the head F with the needle-valve stem, the latter is cut away or indented, as at c c, Fig. 3, and the material of the headlF is then sufficiently compressed as that it shall enter' these indentations, whereby the two parts are very iirmly secured together.

Previous to this invention it has been cus tomary, in instances Where a separate head or key and valve-stem have been employed, to attach said head by means of a pin running therethrough, and through the valve-stem as well.

The means illustrated are obviously more advantageous than this old form ot' connection, particularly in a situation like the present, wherein an accurate adjustment of theV head with respect to the needle-point is desired.

The valve may, under ordinary circumstances, be manipulated by simply applying the thumb and forein ger to the head F; but, in case this becomes over-heated, a nail or other implement may be inserted through the perforation provided, the same as in the nipple-block.

G is the drip-cup, wherein the initiatory supply of oil is burned. It is attached to the packing-tube A by crowding it thereon, or by allowing it to rest upon a narrow projection and beneath the socket H.

The burner isl operated substantially as follows: The plug N, which controls the passage of oil from the supply-pipe O, is opened, and the packing-tube allowed to lill. The needlevalve u is then retracted from its seat until a sufficient quantity of oil Vhas run down into the drip-cup Gr to nearly lill the same, when it is returned to its closed position. The lighted match is applied to the oil in the dripcup, and when the burner is sufficiently heat- -ed to generate the necessary gas the needlevalve is gradually opened until the flame assumcs the proper or desirable size. rI`he flame should be regulated by use ot' the needlevalve; and to shut off the gas entirely this valve should be closed rst, and the yalve N shortly after, or when the burner has become cooled a little.

In this class of burners, known to the trade as plate-burners, much difficulty has been experienced from the bending of the plate E, which, of course, destroys the shape of the llame, and thus the efficacy ofthe burner itself.

To obviate this diiculty. I cast a re-enforcement (shown at d, Fig. l) beneath the lowermost portion of' the plate, and this is found to thoroughly prevent the damage alluded to, under ordinary circumstances of using and handling.

It is found to be almost essential that the plate E, against which the flame impinges, should be made of cast metal, (preferably brass,) that the burner should produce the maximum results of which it is capable from the nature of its construction and arrangement of parts. This is due to the superior heat-conducting power of the cast metal over that of the stamped or sheet metal, of which some burners have heretofore been constructed.

The light aorded by this burner is found to be very brilliant, steady, and sufficiently intense for all manner of indoor or domestic illumination.

The several elements of which the device is composed are easy of construction, and not in the least diflicult to be understood and operated by ordinary persons, or those not otherwise well acquainted with the art.

A shade or reiiector attachment for vaporburners has come to be a desideratum, since, by the use oi' such shade or reflector, the light may be the better directed downwardly toward a table or other point, and thus more economically and advantageously used.

It is found that the globe ordinarily placed over gas-burners will not operate successfully in connection with burners of this class. To supply the want specilied I have designed the following simple means of supporting the shade or reflector M: Around the packingtube A, I place a loose spool, I, having the projecting rim or iange K, with circumferential groove g. This may occupy any desirable position upon the tube A, and, under or- -dinary circumstances, is allowed to rest upon the upper surface of the elbow-joint. (Shown in Fig. 1.)

The shade-holder arms L L springv from an adjustable ring, which is placed in the circumferential groove g, and there held by the sliding clasps P P, in the manner sometimes adopted in connection with kerosene-lamps, The arms L L support the shade M above and around the burner, as shown.

In case a portion of the shade be darkened, or it be replaced by a reiiector, the looseness of the spool upon the tube A will readily admit of the arms and shade or reflector being revolved about the light until brought into the desired location.

The attachment of the shade-holder, being about the central burner-supporting tube,

gives a symmetrical exterior appearance to the whole device, while the little distance which the flame is removed from the axis of the shade is found in no way to detract from the value or quality of the light.

The holder-spool may be made with horizontal or vertical sockets to receive the arms of the holder directly; or it may be otherwise modified without departing from the spirit of the invention, so long as it be attached to the supply-tube ofthe burner, or to some part adjacent thereto. y

Having` thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the curved deflectorplate E, the separate packing and supporting tube A, and the removable nipple-block, substantially as shown and described.

2. In a vapor-burner, the removable and ad justable nipple-block held to its seat by the lateral C attached to the deector, the several parts being arranged substantially as shown.

3. In a vapor-burner having a curved deector, and in which the flow of gas is regulated by a needle-valve, the combination, with such deiector, of an adjustable nipple or valve seat, whereby the flow of gas may be directed toward any point of said deector, for the purposes explained. y

4. In combination with a needle-valve the stem of which isA indented, as explained, a head or thumbpiece attached thereto by compression, in the manner set forth.

5. In combination with av vapor-burner, a loose spool applied about the supporting-tube thereof, and adapted to sustain the shade or reflector sustaining arms, substantially in the manner set forth. Y

6. In combination with the main tube A, leading to a vapor-burner above, the spool I, having the flange K, with circumferential groove g, constructed and arranged as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.
