HYDROCARBON-BURN ER.

SPECIFICATION forming part of Letters Patent No. 621,932, dated March 28, 1899.

Application filed July I 1897- Serial No. 648,142. (No model.)

To (LZZ whom it may concern.-

Be it known that we, ORVILLE P. MOON-and HERMAN L. MARBACH, citizens of the United States, residing at Lorain, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon-Burners; and we do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to hydrocarbon or oil burners of the variety in which the oil is vape orized from a wick; and the invention consists in the construction, arrangement, and combination of parts, substantially as described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of our improved burner with part of the drum broken away to show the guide and support thereon for the perforated mixing-tubes. Fig. 2 is a vertical central sectional elevation of the burner on a line corresponding to 5 5, Fig. 4. Fig. 3 is an inside elevation of the locking mechanism for the means shown for raising and lowering the mixing-tubes, as hereinafter fully described. Fig. 4 is a plan view of the burner-base, showing the base to be a distinct and separate part; and Fig. 5 is asectional elevation thereof on line 5 5, Fig. 4, omitting the valve-controlling mechanism. Fig. 6, Sheet 1, is a front elevation of the mechanism for fixing the limits of rotation of the burner-valve and of the locking mechanism for the tube-controlling crank-rod, shown also in Fig. 3. Fig. 7, Sheet 1, shows one of the side supports for the mixing-tubes and the drum.

The construction thus shown comprises a number of original and novel parts and combinations, among which may be mentioned first the base A, which is the supporting member of most of the other parts and in itself has several novel features of construction not hitherto known in this art. This base is preferably cast from brass or other suitable metal and is of skeleton or spider form, with string portion 2, having a slight rib 3 centrally on its top, on either side of which are soldered or otherwise securely fixed the wick-tubes B.

.The wick O rests between these tubes and is movable up and down by means of a rack 4:,

which is secured to the wick enveloping and engaging sleeve 5 and actuated bya pinion 6 on the spindle D, which has a hand-wheel 8 outside the stove for controlling the position of the wick at the pleasure of the operator. Now one feature peculiar to this base A is the construction most clearly shown in Figs. 4and 5, where it will be seen that said base is cast with a depending portion 10, having a pocket or chamber for pinion 6 and a bearing for the inner end of spindle D, and said pocket or chamber is closed by a bearing-nut 12 and a packing-nut 13, penetrated by spindle D and supporting the same. On the opposite edge of the base from hanger 10, or rather at the rear thereof, is another dependent portion 14:,

which has a duct for conveying the oil from the supply pipe E to the wick or wick-chamber. Then about the exterior of rim 2 are castin this instance fourseveral arms 15 in the same horizontal plane and serving as a rest or support for the lower drum F, which surrounds and incloses the wick-tubes from end to end.

It will be seen from the foregoing description and Views that the base A contains in itself the wick-adjusting mechanism, and in Fig. 2 is shown a well 18, suspended from hanger 10, in which the lower end of the adj usting-rack at is inclosed.

Now as a further feature of this invention we employ mechanism for raising the perforated mixing-tubes and the drum about the same-f1rst, to avoid creeping of oil on the same, and, secondly, for lighting the wick, and comprising two side pieces G, consisting in this instance of fiat metal strips or bars sliding in guides 20 on the exterior of the outer tube 13 of the wick-chamber and secured rigidly to the outer mixing-tube L at its top.

' From this point the said strip or bar is bent laterally and downwardly and constructed at its extremity to rest the drum M upon and support the same independently of the mixing-tubes.

The foregoing construction is shown most clearly in Fig. 7, and the two sliding uprights G are opposite each other. Then midway intermediate of these, quarter-Way around the burner, are the brackets or hooks 21 to further support or rest the drum M. The two tubes K and L are tied togetherby rods 24,

ICC

as is now common; but the drum M, which is hereby arranged and supported to be lifted and lowered with said tubes, is free to be separately removed, if desired, and this is deemed a great convenience on several accounts. \Vhen down in operation, drum M rests on the lower drum F. Rods or the like may be substituted for the strips or bars G, and any suitable arrangement of guides may be used therewith. The said bars G extend below the wick tubes or chambers and are there engaged by what we term a crank-rod N, which is so supported and bent as to come across beneath and in contact with the ends of the bars G G and raise and lower them according to the way the said rod is turned.

Referring now to Fig. 4, the shape of said rod N is clearly shown, and it is supported in a long bearing 14, Fig. 1, whence it extends, as seen in Fig. 4, affording a crank portion across beneath the center of the burner to actuate bars G, as described. A counterbalance, consisting here of a weight 26, though a spring may be used, operates the rod N automatically. At the opposite or front end of this rod is engaging mechanism, whereby the rod is so held when the burner is in use as to rest tubes K and L about the wick and is released when the fiame is extinguished. This lock comprises a sliding bolt ll, having a finger-hook 4% to withdraw it when necessary by hand, and an inclined engaging rod 31, traversing a vertical slot in the fixed plate P. Hence when the mixing-tubes are down the rod N, having been depressed past point 81, the bolt is held down thereby, as in Fig. 3, and when the said lock is released and the counterweight is down, as seen in dotted lines, Fig. 1, the said combustion-tubes and their drum are raised and said tubes are lifted away from the wick, as in Fig. 2, and creeping of the oil over said tubes is prevented. This is a Very desirable arrangement and result, because obviously the wick is constantly saturated with oil, and when the stove is idle there is unavoidable creeping of the oil over the combustion-tubes and other exposed parts if said tubes be allowed to remain down on their seat next to the wick, and the consequence is that very disagreeable odors are given off when the burner is again lighted. All this is prevented by our construction, because as soon as the burner is turned off after using the tubes are automatically raised from their seats by the counterweight or balance, as in Fig. 2, and creeping of the oil is prevented.

Now referring again to Figs. 3 and 6, the plate P is shown in reverse sides, the rear view being in Fig. 3 and the rear View in Fig. 6, and in this plate is the vertical slot 30, through which the counterweight-rod N projects. Outside of this plate, on the end of rod N, is the head 27 or its equivalent, adapted to be pressed by the finger of the operator, whereby when the rod is to be depressed and the combustion-tubes lowered this head is convenient to lay the finger upon and bring said parts into working position. Then to keep said rod down in slot 30, as in Fig. 3, the bolt or look H operates as already described. This bolt in this instance has slots, and headed bolts or supports through said slots enter into plate P, which afford room for its adjustment back and forth. The wickadjusting spindle D likewise projects through plate P, and on this spindle is sleeved a device adapted to not only fix a limit to the rotation of said spindle, so as to have the rotation limited at any time within a certain ascertained distance, more or less, but also to change the limits at will that thereby the wick may be turned higher or lower and so as to remain at that adjustment until purposely changed. This enables the wick to be set high'or low at any desired point, with the assurance when you come to operate the burner that it is not going to be too high in any rotation you can give. The wick can be left at a lower point, but cannot be turned above the fixed adjustment, without changing the adjustment. Thus excessive firing .is prevented and uniformity of flame and heat is obtained.

Now referring to Fig. 2, we see a sleeve on spindle D, secured by set-screw or the like, and on the outer end of this sleeve is a toothed ratchet-wheel 36, Fig. 6. Upon said spindle and extending partly over said wheel on opposite sides is the rotatable arm Q, having a small worm-wheel 39 in one end engaging in said ratehet=wheel 36 andby the rotation of which the arm is rotated in respect to the said ratchet. A stop projection 40 on the other end of the arm is adapted to engage a side lug 41 on bolt plate H, and thus limit the rotation of spindle D to the right, the opening direction. On the inside of plate 1, Fig. 3, the sleeve 35 is shown as having a finger 42, adapted to engage a projection on the bolt 31 when the Wicks are turned down and the flame extinguished, and this engagement and movement of said bolts are just sufficient to release weighted rod N, thereby allowing it to act andlift the combustion-tubes, as seen in Fig. 2. A spring 43 or its equivalent serves to always keep bolt 31 in looking position as in Fig. 3. It will be observed that by this construction the interior of the wick-tubes is clear of all adjusting mechanism, while the inixing-tubes and their drum are raised and lowered by devices wholly on the outside of the said wick-tubes and engaging the outside of the outer mixing-tube. Furthermore, the means for raising and lowering the said mixing-tubes are independent of the wick-controlling spindle, in this sense that the moment rod N is released the counterbalance 26 raises the said tubes. This rod N may have any desired shape or position, and it may be substituted by any equivalent construction, the essential consideration being that it should operate, substantially as shown and described, to lift the tubes when the counterbalance comes into action.

What we claim as new, and desire to secure by Letters Patent, is

1. In a burner,perforated combustiontubes and wick-tubes to support the same,rods fixed to said combustion-tubes at opposite points and guides on the outside of the wick-tubes for said rods, in combination with lifting mechanism engaging the lower ends of said rods, a lock for said lifting mechanism, and a wick-controlling spindle operatively connected with said lock,whereby when the wick is lowered the said lock is actuated to release the lifting mechanism, substantially as de scribed.

2. The burner substantially as described having a wick-chamber and a wick, means to raise and lower the wick comprising a rotating spindle, a pinion on said spindle and an arm on the spindle carrying aworm engaging said pinion, said parts serving to adjustably fix the limit of rotation of the spindle, substantially as described.

3. In hydrocarbon-burners the wick-tubes and the combustion-tubes, and a wick-controlling spindle having a projecting finger rigid therewith, in combination with a counterbalanced crank-rod and means engaged thereby to raise the combustion-tubes, and a look for said crank-rod engaged by said finthe spindle comes to a stop in its rotation for turning down the wick, substantially as described.

Witness our hands to the foregoing specification this 4th day of June, 1897.
