Specification of Letters Patent.

Application filed May 27, 1916. Serial No. 100,394.

To all whom it may concern:

Be it known that we, FRED E. VI-UTE and FREDERICK E. Hoornn, both citizens of the United States, and residents of (irardner, A

(the wick so as to limit the upward move.

ment of the wick and to provide a central air distributer perforated to supply an to the flame, and, to provide one or more flanges above'the wick stop, such a construetion being shown in the patent of Berge,

739,143, September 15, 1903.

6, 1894, also shows a form of wick stop and aperforated air distributer, while patent to Williams, 662,583, November 27, 1900, shows a wick stop connected 7 to a perforated spreader, which spreader inturn carries defleeting flanges.

Our improvements have to do with this general type of stove, namely, in which a wick stop .is used carried by a perforated cylindrical distributer and having a flange or"fl'anges either intermediate of theends of thedistributer or located at the upper ends of the distributer for deflecting the air outwardly, but principally consists in the de-' 40 tails of construction, differing from the art referred to in that the distributer carries loosely the stop and also carries looking means e'fictive on the raising of the wick to limit the upward movement thereof but automatically detachable when the distributer itself is lifted by hand for the purpose of access to the central air tube as for cleaning. Our invention is not limited to any particular type of spreader or air distributer,

do we restrict ourselves to any'particu- The patent of Robin s, 514,036, February lar type of oil reservoir as we show two forms in the drawings accompanying this application.

In these drawingsFigure 1 is an elevalDIOIl of a reservoir of one type to which our invention is shown as applied; Fig. 2 is a sectional. view showing the air distributer and wick stop with parts in elevation; ,Fig. 3 is a like view with the distributer ready for removal; Fig. 4 is a view a quarter turned from Fig. 3, showing the wick stop and air distributor detached; Fig. 5 is a modification of the oil reservoir.

In these figures the reservoir A is of the ordinary type and as shown in Fig.'2.the- ..ick

tubes 1) b extend through the sametermt nating in a closed pocket'some distance beneath the bottom of the reservoir, the oil being fed to the wick tube through openings a, 1n the outer wall of the wick tube near the bottom of the reservoir. well known type of reservoir and wick tube we may, as shown in Fig. 5, provide only an lnner tube 6' within the reservoir B and allow the wick to extend into the reservoir wlthout being fully covered, the upper end of the wick only passing between two annular walls, the outer one extending only part way down, as shown at c c. In this case we may form the reservoir as shown in Fig. 5, with a depressed central portion 03" ter- .minating on a level with the bottom of the tube 6".

As is well known, it is very desirable in the type of burner in which the flame burns from the exposed side of the wick, .to have a stop to limit the upward movement of the wick to a previously adjusted position which will give the very best results without smoking and without undue charring of the wick, and it is also desirable that this stop be readily removable for the purposes of 'cleaning or for gaining access to the interior of the stove for other purposes.

Instead of this To this end we utilize a perforated air distributer (Z, which is ofordinary construction preferably having a protruding shoulder e and extending flanges f, 9, all of which are old and well known for distributing the air to the flame. The wick stop It is loosely secured to the air spreader or distributer by a rod 2', connectedat its ends to the body of the wick stop and passing through elongated slots is, in the imperforate part of the spreader 'd,-so' as to have limited movement up and downlin relation thereto.

The upper partof the :wick stop is turned over toprovide a-fiange Z and perforations are provided directly beneath the flange. The upperendof the Wick stop is slightly flared outwardly forming a recess m, and

this is covered by the narrow flange 6 when the-parts are at rest in normal position in the lamp or stove. T a

Within the central draft space a skeleton frame! n is secured'with the' central part 0 supported by arms jmand thecentral part acts as a catch over the edges of which the latches r, engage as shown in Fig. 2 when p the parts are in normal position,- these latches'being pivoted to the 'rod 2' and having their upper ends formed withtriangular shaped openings as shown in the figures at s which engage a staple t so that in the. upward movement of the spreadend the latches r are opened and disengage from the disk 0, enabling the spreader and its attached wick stop to be lifted and removed from its position within the draft tube. When, however, the parts are in normal po- S IlZIDTFZXSNShOWH in Fig. 2 the latches are may be given vertically before the latches. engage the .disk at which point the'movement comes to a stopand so long as the upward pressure is through the flange of the wick stop by means of the wick there I is no disconnection, but when the flange g is grasped and lifted as in Fig. 4 the latches are immediately spread apart as in Fig. 3 and the distributer with its wick readily lifted. I

We also utilize an outer perforated shield u, this'being of ordinary construction and location.

.What we claim is j, i

1. In combination with an air distributer, a wick stop having vertical movement, a locking device for limiting said movement,

and means for releasing said locking device for the removal of the wick stop, substantially as described. a

2. In-combinati'on with an air distributer, a wick stop loosely connected therewith and having vertical movement therewith, with locking means for the said parts automatically detachable when the air distributer is manually lifted, substantially as described.

3. In combination, a wick stop'having an stop is outwardly flared upper end terminating in a projecting flange, an air distributer having a loose connection with the wick stop, a pair of pivoted latches and means for giving lateral movement to the lower ends of the latches in the manual lifting of the air distributer to unlatch the same from a fixed part of the burner, substantially as described. I

4. In comblnation 1n a lamp stove, an air distributer, a wick stop connected to the airdistributer by a rod secured in the Walls of i the wick stop and extending through slots in the walls of the air distributer, latches pivoted on said rod and having their upper ends slotted, and in connection with a fixed part of the air distributer, and a catch car ried by a fixed part of the burner'underwhich the ends of the latches pass, and with which they engage on the raising ofthe wick stop but from which they are disengaged by the initial lifting of the air distributer, substantially as described.

In testimony whereof, we aflix our signatures.
