Briey stated, the invention Vis a body heater which includes the combination of wearing apparel and heating means therefor, and with the apparel having a circulating system so that the heat will be properly distributed. illustrative of the manner in which the invention may be practiced is by the use ot' a jacket or other article of apparel having a closed compartment with an opening in each of the two sides and a plurality of Iopenings in the top and bottom to allow circulation. A heater casing or container adapted to 4contain suitable heating means is carried within the closed compartment.

illustrative of the type `of heating means thatrnay be employed is a burner of conventional character which utilizes propane gas or other fuel from a burner supplied from a [disposable tank, such burner extending through an opening in the side of the container. The disposable fuel tank is reversible so that the burner may be inserted in either end of the container. Also the fuel tank may be secured in place by means of an encircling spring at the bottom of the container.

The container is surrounded by heat insulating material such as asbestos or the like and the pocket of the jacket in which it is inserted lik wise is of heat-insulating material. The pocket may be either fined or detachably secured to the jacket or to the article of wearing apparel, the insulation of the container preventing injury to the wearer.

As the air in the combustion chamber container is heated it rises and passes through the openings in the top of the container thus allowing cold air to enter the container through the openings in the bottom. The hot air circulates around the body of the wearer so that the blood in that area receives the heat and the various parts of body are maintained warm.

With continued reference to FlGS. 1 to 6 of the drawing, the body heater of t le present invention comprises a jacket ld having a pocket l with a liner i2, secured therein by means of stitching lf. The lower edge of the pocket extends to the lower edge of the jack l@ slightly below the belt le which holds the trousers l5.

The jacket lll may be made of any desired material capable of insulating against the passage of heat to thereby retain the body heat. A heater and a circulating system may be provided such as for example the heater disclosed in the above identified abandoned application Serial arrasar EndY movement of the fuel tank 2d is restricted by the angular disposition ofthe nozzle 2b within the opening l?, the nozzle 2b being adapted to be inserted in either or" the openings TLS or li for right or left hand operation.

The heater casing lo is provided with top and bottom members 2o and 27 rd soldered, welded, or otherwise secured in place, and having perforations 23 and respectively for the flow of air into and from the casing. Hot air heated by the burner 2% will pass upwardly through the openings 28 and will be replaced by the colder air entering through the openings 29 in the bottom 27.

Yas over the ends thereof. rl`he upper portion of the heater casing is provided with an insulating sheet or covering 32 and an overlying cove 'ing of cloth or other material 35. The insulating sheet 32 and the cloth 33 are provided with a series of openings 3d and 35, respectively which, with the openings 28 in the top of the heater casing 16, permit the discharge of heated air and combustion gases for distribution within the garment in contact with the body of the wearer. ln like manner the bottom of the heater casing is provided with a reinforcing platefor strip 36 having openings 37 for the entrance of auxiliary air to assure complete combustion and for air to be heated, and the bottom of the heater casing l and the reinforcing plate of strip 3d are provided with insulation 33 which joins the insulation 3l at the ends of the front and back of the eater casing l5. The insulation 38 is provided with openings 39 for the flow of air ther through, the insulation being covered with a bottom layer of cloth il and having similar periorations l for the ilow of air therethrough. rEhe spring is held in place by eye bolts 42 (FlG. 2), the bottom 27 and the reinforcing member 35 providing sumcient strength to support such eye bolts, the spring 25 and the disposable fuel tank 2d. The cover sheet has its front and rear extremitiesV extended upV- wardly along the insulation Si? about the heater casing and on the inside next to the person the insulation El? is provided with a clothcover sheet d3.

in PEG. 5 the structure is similar to that ofthe preceding gures except that the liner 12 is provided with an end fold l2. for the reception of snap fastener elements 44.- for engagement by com lementary snap fastener elements on a reinforcing strip 46 carried Within the garment lil. Thus the pocket and the heater may be detached from the garment. l e

It will be apparent from the foregoing that a body eater is provided which is a compact arrangement of garment with a pocket or compartment and a heater hav-Y infr openings bottom and top for the inlet and discharge respectively, or" air to be circulated beneath the garment for heating the wearer. Also it will be apparent that the Y structure is relatively inexpensive, simple to produce and use, and can be operated eiciently at small cost.

instead of being built into the garment, the heater of .Fl 5 Vmay be independently supported by a 'strap 47; The heater may be suspended by the shoulder strap 47 beneath jacket EL@ With'the disposable tank shoulder cured thereto.

Referring to the burner 2li, it will be apparent that air holes EA are provided for obtaining air for ombustion SS- n Y within the burner head 2d and such air can be adjusted in the usual manner and the burner disclosed in the other modifications are similar including the burner 213A.

Referring to the modiiication shown in FIGS. 7-10, inclusive, the heater includes the upstanding housing of oval shape crosswsection providing a combustion chamber, the lower end llZl and the upper end wall 122 being provided with openings for the ingress of air and theV egress of air and products of combustion respectively. A non-combustible insulating jacket made of asbestos sheet material E23 surrounds the side Walls of the housing and a flexible stocking like sleeve 124 surrounds the asbestos insulating jacket l23 and protects the asbestos irom abrasion and damage and also retains the insulating jacket in position while the sleeve 124 also provides additional insulation to prevent a person from being burned by heat from the combustion chamber. A tension spring ld is secured to the bottom end of the housing on suitable lugs or the like and such spring underlies the bottom receivinc and retaining a fuel tank i3?. in position under the housing. A burner head receiving opening lid is provided in the housing, and in the insulation jacket for receiving a burner nozzle or burner head 128. A tubular extension i217 is secured to and projects from the combustion chamber serving as a guide and guard for the burner head L13. A layer of non-combustible material such as an asbestos sheet 125A is secured to the outer surface of the sleeve 24 adjacent the nozzle guard 97 to prevent burning during the insertion of the lighted nozzle into the combustion chamber.

A 129 made from av rectangular blank Vof stainl less steel or other suitable material is secured at one of its ends by means of a downwardly turned'llange 130 and rivet 3353A to thc adjacent Wall ofthe housing 129 above the burner receiving opening 12d in the guard and guide f tube iff? in a position overlying the burner head 128 and causing heat from the burner to be deliected. The rectanguiar baille 29 is provided with side anges 131 along the adjacent edges extending from the ange i? where such side iianges are nearly horizontal to the free end where the flanges i3d are vertical for conlining the flame to the lower portion of the combustion chamber. The flanges 131 are separated adjacent the nozzleY receiving opening li to avoid contact of the burner head during insertion. `It will be noted that the bale l2? extends from the `attaching flange i3d toward the opposite Wall of the housing defining the combustion chamber to thereby cause uniform heating of the housing and gases therein.

The fuel tank 132 of the conventional propane type is rovided with the usual nipple :132A which is received by a female connection in a pressure regulating valve of the Sensitne type. This valve E33 includes adjusting lcnurled knobs i3d which are preset at theV factory to limit the iiow ci fuel to a maximum permitted within the housing to avoid dangerous heating thereof and therefore the adjustment cannot be varied except by a person skilled in this particular field. The adjusting knobs 334,

' 234A are threaded onto a threaded shaft iSd-B to provide a limit stop engaging against the hub 134C to determine the position of the valve at maximum openinv. The burner head E28 is mounted on a tube 135 extending from the valve and such burner head is of awell known type and is adapted to be received in the guard and guide Y is no danger of tire during the insertion of the burner when llame is formed therein. The valve assembly is mounted on the tank 132 by having the internally threaded boss l5@ of the body 133 arrasar efective oper rted, a hook i923 is formed ly and serves to engage the will always be maintained 'i After ythe rod i3d is e therein which opens upward eye in the free end of the coil sp tachment when inserting or removing racing a fuel tank 132.

The valve arranger cit assures a limited low of gas and that there is no danger of overheating, vthe iiame size being controlled to limit the size oi' the llame so that the inner cone is the nature or" one-half inch high while the outer cone does not exceed half the width of heating chamber. Y

A tube 15:55' (FIGS. 7 and 8) of conducting material such as metal extends along the side of the housing 2112? in heat conducting relation and is heated by conduction from the vhousing in the middle portion of the tube and a iiexible tube itil extends` from the tube to a nose receiving cup 3.42 similar to the nose receiving cup Z9 described in another modincation so that such nose cup is adapted to be -located adjacent the nose to provide heated air to be mixed with other air and'thereby prevent excessive cooling of a persons lungs.

Referring to EEG. S the strap is shown as secured to lugs adjacent the top wall M2 md the sleeve like fabric covering lfl and asbestos insulating covering i extend above the upper end wall l2?, and thereby provide a chimney to further guide heatedV air from the combustion chamber into the space between an outer garment and the body adjacent the heart thereby heating a persons blood.
