Specification of Letters Patent.

Patented Sept. 15, 1908.

Application led November 25, 1907. Serial No. 403,823.

T o all whom it 'may concern.'

Be it known that I, CHARLES E. VARNUM, a citizen of the United States, residing at Lawrence, in the county of Douglas and State of Kansas, have invented a new and useful Heater, of which the following is a specification.

This invention relates to ortable heaters of that general class especia ly designed for use in carriages, wagons, automobiles, sleighs and other vehicles and has for its object to provide a comparatively simple and inexpensive device of this character which per-` forms the dual function of a hand and foot warmer.

A further object of the invention is to provide a heater including a casing having spaced longitudinal partitions defining superposed heating compartments, there being perforations formed in the end walls of the casing to permit the free circulation of air through said compartments.

A further object is to provide a hood or shield for deflecting the hot air from the burner laterally and downwardly into contact with the partitions so that the hot air may be distributed uniformly throughout the casing. .i

A further object is to provide improved means for locking the lamp within the casing, and means for regulating the size of the flame at the burner tip.

A still further .object of the invention is generally to'improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportionsand minor details of construction may be resorted to within the scope of the ap ended claims.

n the accompanying drawings forming a part of this' specification: Figure 1 is a perspective view of a heater constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view taken on the line 3*3 of Fig. 2. Fig. 4 is a bottom plan view of a portion of the casing.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved heater forming the subject matter of the present invention includes a casing or housing having a flat perforated base 5 and a semi-circular top or cover 6, the metal forming the base 5 having its opposite transverse edges bent upwardly to form perforated walls 8 and itslongitudinal edges bent laterally to produce longitudinal flanges 9.

The cover 6 is ofi` set at 1 0 lto forni a pocket for the'reception of a strip of asbestos or similar insulating material 11, the latter being covered by a jacket 12 preferably formed of carpet or similar material so as to give the heater a neat attractive appearance as well as to form a yieldable treadsurface.

The metal forming the top or cover 6 is provided with spaced circumferential strengthening ribs or corrugations 13 while the opposite ends of the metal are extended longitudinally beyond the end walls 8 and thence bent inwardly to form grooves 14 adapted to receive suitable flanges 15 carried by the end walls thereby to lock the cover in engage ment with said end walls.

The opposite ends of the flanges 9 are bent to form laterally extending retaining ears 16 which are riveted or otherwise rigidly secured to the adjacent end walls, as indicated at 17, the metal forming the rooves 14 being cut away to accommodate t e ears 16, as shown.

The opposite longitudinal edges of the cover 6 are bent to form vertical flanges 13 which engage the flanges 9 and form longitudinal grooves for the reception of the adjacent lower edges of the insulating material and fabric jacket whereby the several parts may be clamped together when the ears 16 are s ecured to the adjacent ends of the casing.

Arranged within the casing are spaced longitudinal partitions 19 and 2O defining a plurality of superposed heating com artments, said partitions being formed wit o enings 21 so as to permit the heat from the amp or burner 21 in the lower compartment to pass through the openings in the partitions to the upper compartment.

Arranged in the u per heating compartment is a hood or shie d 22 provided with laterally extending lugs 23 which are riveted or otherwise secured to the upper partition 20.

The hood or shield 22 extends longitudinally of the casing and is provided with o po'- sitely disposed openings 24 through w ich the hot air passes in contact with the reinforced walls of the cover.

The heater 21 is preferably in the form of a lamp the body portion of which is seated in a circular opening -25 formed in the bottom of the casing and is provided with laterally extending lugs 26 which engage the reinforcing flange 27 of the opening 25, there being oppositely dis osed recesses -or depressions 28 formed in tie walls of the opening 25 so that by forcing the lugs 26 upwardly at the depressions 28 and then artially rotating the lamp the latter may bellocked in position on thebase of the casing.

The burner 29 extends through alined openings 30 formed in the partitions 19 and 20 and is provided with a removable cap 31 having one or more bars 32 secured thereto and extending transversely across the wick so as to regulate the height of the flame at the burner tip,

Mounted on the burner tube 29 and preferably bearing against the lower partition 19 is a removable disk or collar 33 preferably formed of asbestos or other suitable insulating material.

The base of the casing is preferably reinforced and strengthened by one or more transverse ribs 34, the metal at the opposite ends of the casing being pressed downwardly to form depending feet 34 which serves to support the base of the casing in elevated position above the bed of the carriage or other.

suitable support.

In operation the lamp is filled with alcohol or other fluid and inserted in the opening 25 in the base of the casing by rotating the lamp until the lugs 26 register with the recesses or depressions 28 after which the lamp is partially rotated which causes the lugs V26 to engage the reinforcing flange 27 and thus lock the lamp in position in the lower compart ment of the casing.

It will thus be seen that the hot air will strike the hood or casing 22 and be deflected downwardly into contact with the upper longitudinal partition 20 and thence pass through the perforations 21 to the intermediate and lower compartment, the fresh air at the same time entering the casing through the perforations in the end walls thereof thus permit ting the free circulation of air both longitudinally and vertically of the casing.

Attention is here called to the fact that the lower longitudinal partition 19 is provided Awith depending supporting flanges 35 which bear against the interior Walls ofthe casing at the base of the latter and engage similar flanges A36 formed on the upper partition 20 and serve to 'force the flanges 36 in engagement with the side walls of the casing thereby to prevent accidental displacement of the same.

The heater is provided with a suitable handle or Enger piece 37 by means of which the casing may be conveniently transported from place to place.

The heaters may be made in different sizes and shapes and used as either a foot or hand warmer.

on converging lines with their terminal por-- tions disposed in contact with each other and resting on the base of the casing, said partitions being provided with vertically alined openings, a lamp seated in one of the heating compartments and provided with a burner extending through the openings in the partitions, and arhood disposed within the upper compartment at said burner.
