CORPORATION or msssnomrsnfrrs 011- BURNER AND SUPPORT THEREFOR Applieation filed July 22;

This invention relates to range oil burners and more particularly to devices for locating the combustion chambers, usually of a twin burner,- within the fire pot and below the lids ofthe range.

Range oil burners of the type disclosed in the United States patent to Johnson and Leach No. 1,764,794 dated June 17, 1930, owned by the assignee of this invention, are sold generally to householders and because of the large variety of types of domestic rangesstill in use it is essential that there be sufiicient flexibility or universality in the burner mountings-to enable a, proper installation regardless of any special feature of construction within the fire box.

With this object in view the present invention comprises the features and combinations of parts hereinafter described and then particularly pointed out in the appended claims; and its nature and scope will be understood from a description of the preferred embodiment illustrated in the accompanying draw- 5111?, in which:

;i are 1 is a view, in perspective, of the comp ete burner support;

F1g. 2 is a perspective view of the adjuster, detached; and

Figs. 3 and 4 are views,-in section, of the fire boxes of two difierent types of range illustrating the use of the adjuster in efiecting a proper installation of the burner.

In the embodiment of the invention illus-' trated in the drawings the oil burnermay be r of any of the well known types now on the market and the illustration in Figs. 3 and 4 represents the twin burner of the above named Johnson and Leach patent having a web 2; joinin drille or otherwise perforated to receive a standard for su porting the burner.

- The combine support and adjuster is shown in Fig. 1 and comprises a casting providing a base- 10 and a vertical tubular socket 12, the latter for receiving a supporting post 14 held in any desired vertical or angular relation to its socket by a set'screw. h e base 10 is generallytriangular in plan and 1s rovided with leveling screws and a hol 'ng bolt, as shown. An adjuster 16 comprises a "form a chute under the grate when burning the two combustion chambers 4,

bar' having a longitudinal slot 18 and a threaded aperture 20 both being cut through from the upper tothe lower face of the adjuster. Conveniently the lower face of the adjuster is rabbeted about the slot providing an interior shoulder 22. The adjuster is attached to the support by screwing it onto the upper end of the post 1 1 thus forming a horizontal arm on the post.

Many types of domestic rangesk'have fire boxes so constructed that the base 10 of the support cannot be bolted to thefloor with its post 14 central of the width of the fire box.

4 port-and adjuster will be understood.

1n Fig. 3' the oven wall 24 is inclined to coal thus reducing the width of the floor with respect to the width of the fire box above it.

Ubviously the support cannot be placed far enough inward to permit the post 14 to be threaded directly into the central web 2 of the burner and seat the combustion chambers 7 below the lids. This difliculty is overcome b securing the burner to the adjuster 16 whic trally by a direct connection to the post 14. 'In this case the post is turned angularly within its socket until the attached adjuster 16 projects outward over the chute or into the central ortion of the fire box.

Ineit er illustrated case, or in any similar case where the features of construction of the range prevent a central-position, laterally, oi

the post 14, the burner. 1s secured to the adjuster by a bolt pased through the slot 18,

is turned to project inward over the chute 24 its combustion chambers beneath the range lids regardless of the lateral position of the base or the support.

Some ranges have uneven floors formed by ribs or other obstructions so that it is impossible to bolt the support in its proper longitudinal position relative to the two range lids. In installations where the support is oil-center longitudinally the post 14 is loosened and turned angularlywithm its socket until a portion of the adjuster slot 18 is at the central point whereupon the post is secured and the burner mounted on the adjuster as hereinbefore described. The desired vertical position of the burner is attained by a vertical adjustment of the post 14 within its socket l2.

The nature and scope of the invention having been indicated, and its preferred embodiment having been specifically described, what is claimed as new is 1. An oil burner for use in a range having a fire box of the type in which lateral partitions or the like extend inward and obstruct the lower portion of the space centrally below the range lids, having a substantially vertical support secured in a fixed position within the fire box necessarily laterally off-center with respect to the range lids due to interference by said lateral obstruction with a central securement, said support projecting upward to a point above saidobstruction, a combustionchamber carried by said support in the open space above said obstruction, and means intermediate the combustion chamber and the support rovidin'g for lateral movement of the com ustion chamber relative to said support to center said combustion chamber beneath the range lids regardless of the off-center position of the support necessitated by said lateral obstruction.

2. The invention defined by claim 1 in which said means for centering of the combustion chamber comprises a substantially horizontal arm attached at one end to said support and having a longitudinal slot open at its upper side, and means between said arm and said combustion chamber adjustable within said slot for rigidly mounting said combustion chamber directly above said arm in the required centered position.

3. In an 'oil burner mounted on a vertical sup ort, for use in a range havingla fire box of t e type preventing-securing t e support centrally laterally of the fire box whereb said burner woul be laterally ofi-center wit respect to the range lids, provision for centering the burner with respect to the range lids comprising an' adjuster consisting of a slotted, horizontal arm projecting laterally from a the support, and means for adjustably securing the burner within said slot to be supported at the upper side of said arm.

4. An oil burner of the type comprising two combustion chambers joined by a central web perforated to receive a supporting post and said combustion chambers to be supported within the fire box of a range centrally beneath the range lids, having means for so centering said combustion chambers beneath the range lids regardless ot a required non-centered position of the post for supporting the burner, comprising a vertically slotted arm extending laterally from the post, and means passed through saidslot for detachably connecting said central perforated web to the upper side of said arm, said burner being supported above and adjustable along said arm to the desired centered position.

5. *An oil burner for use in a range having a fire box of the type in which lateral partitions or the like extend inward and obstruct the lower portion of the space centrally below the range lids, having a substantially vertical support secured in a fixed position within the tire box necessarily laterally off-center with respect to the range lids due to interference by said lateral obstruction with a central securement, said support projecting up- Ward to a point above said obstruction, a combustion chamber carried by said support in the open space above said obstruction, a slotted arm extending laterally intermediate the combustion chamber and the support for connecting said combustion chamber to the support, said slot providing for a variable laterally ofl-set relation of the combustion chamber relative to said support, and means for securing said combustion chamber in the required off-set relation to the support for centering it beneath the ran e lids regardless of the off-center position 0 the support necessitated by said lateral obstruction.
