To all whom it may concern:

Be it known that I, FRANK BATTER, a citizen of the United States, and resident of St. Johns, in the county of Multnomah and State of Oregon, have invented a new and. useful Improvement in Portable Foot and Bod r Warmers, of which the following is a specification, reference being had to the accompanying drawings as constituting a part thereof.

This invention relates to devices which are designed to be worn on the person as a means for artificially warming the body, head and feet, so as to enable the person to better stand exposure to cold weather.

To this end, my invention comprises the contrivances, combination and features hereinafter described and illustrated in the drawings.

the two circulation tubes connecting a valve bulb with the fluid heater and the pad placed under the foot, so as to join the two tubes side by side; Fig. 14 isa detail, partly in section, of the helmetpart of my device; and Fig. 15 is a sectional detail illustrating the construction of the casing of the lamp chamber of my device.

The numerals designate the parts referred to.

In its general arrangement, my device comprises a lamp-chamber 1, provided with straps 2, whereby it is adapted to be fastened to the waist of the person, as shown in Fig. 1.

3 is a helmet under which the user wears a skull cap 4. The lamp-chamber 1 is pro into the helmet 3, which in its construction is designed to serve as a flue or discharge for the vitiated air of the lamp-chamber.

1n the upper part ofthe lamp-chamber 1 is removably supported a fluid-heater 9, to which are attached two pairs of tubes 10 10 11 11 connecting at their extremities with a hollow pad 12, to be placed under the hollow of each foot. One of each pair of tubes is provided with a pump-bulb 13, and the whole being arranged to circulate the fluid heated in the heater 9, through the foot-pad 12. For convenience, each pair of said fluid-circulating tubes is arranged alongside of one of the legs of the wearer, and the pump-bulbs 13 are mounted on pads 13 adapted to be affixed on the inner side of the legs near the knees by bands 13. The outlet air tubes 7, -8, are respectively provided near their upper ends with a hollowdisk 14, shown in plan section and cross section in Figs. 6 and 7, and comprising substantially an inner shell 14, having an outer covering of cloth or like fabric 14", and the whole being arranged to be adjusted over the ears of the wearer. Thus the heat of the lamp serves to warm the body, the airoutlet-tubes 7, 8, to supply warmth to the face, and the fluid heater 9, and its connections including the pads 12, to warm the lower extremities of the wearer.

The details of my device in other respects are as follows:

The helmet 3 is constructed of a metal body 3 provided with neck-shield 3 and a rim 3. The top is covered by a cover 3,

leaving air escape apertures 3 I Near the top of the helmet is provided a perforated partition 3 and the body walls 8, are provided with perforations 3 Within'the helinet is provided an inner inclined wall 3, serving to prevent any air blowing in through holes 3 down into the lamp with such force as to extinguish the same. To the helmet is removably fastened a short cloak 15, to be arranged over the shoulders, approximately as shown in Fig. 1, for the purpose of retaining the heat radiated by the outlet tubes 7, 8, about the face. The helmet is secured in place by bands 3.

The lamp-chamber 1 comprises a threepart skiircasing, as illustrated in Fig. 15; namely, an inner metal skin 1*, an intermediate sheeting of asbestos 1 and an outer sheeting of metal 1. The intermediate and the outer sheetings are respectively made with registering holes 1 and the exterior is provided with vertical guides 1, in which is slidably held a slide 1, which when drawn down uncovers the holes 1 and allows part of the hot air ofrthe lamp-chamber to radiate through said holes; and supposingthe wearer to have on an overcoat or cloak, saidradiated heat serves to warm the body.-

When the heat of the lamp-chamber is not to be so utilized, the slide 1 may be adjusted to cover the holes 1.

Entering the bottom of the lamp and extending upward is an air-inlet tube 1 to which is attached the flexible air-tube 5, above referred to. In the lower part of the lamp chamber is a perforated false bottom 1 to diffuse more evenly the stream of cold fresh air entering through the tube 1.

The lamp 1 is removably secured in place by spring arms 1 engaging with lugs 1 and the top of the lamp is conveniently made with aflange 1, fitting within the open bottom of the lamp-chamber.

The inner sheet 1 of the lamp casing has no perforations so as to prevent smoke being blown out.

In the upper part of the interior of the lamp casingare provided brackets 1 and 1 The bracket 1 is provided with a stop 1", and the bracket 1' supports a chamber 1, open at both ends and adapted to receive the fluid-heater 9, which when inserted rests by its inner end on the bracket 1 and is sto ped in'its proper place by stop 1". The uidheater 9 is provided with inlet and-outlet necks 9 9", to which the tubes 10 10, 11 11, are fastened.

In order to provide for the circulation of an ample volume of fluid through the heater 9, over as great a surface of heated metal as practical, the fluid-heater 9 is preferably made of the construction shown in Figs. 4:, 4 4". It comprises substantially two parts .9, 9 each made with a worm-like duct 9 state? 9, through the necks 9*, respectively; the two partsare separated by a partition 9 the whole being rigidly fastened together by rivets 9*, or other correspondingly convenient means.

Since the inner end of the fluid-heater 9 will be exposed to the flame of the lamp, and become more or less soiled by reason of a deposit of soot thereon, I provide a sheath 9, made with a hinge part 9 and when the fluid heater is removed from the lamp-chamber, the sheath 9 is moved over the blackened inner end -soas to drop the hinge part 9 and prevent the soiling of the hands or pockets when carrying the fluid heater about.

The tubes 10, 10 11, 11 connecting the heater with the foot pads 12, are preferably arranged as illustrated in Figs. 10, 12, '13. That is to say, Ifound it convenient to inclose both of said tubes" within a common outer casing 10", made of cloth, wrapped around the same, substantiall as shown in the cross section Fig. 13, to old the tubes side by side.- The pump bulbs 13 I found convenient to make of metal like a circular box, the top 13 of which has concentric circular flutings so as to be springy; and I have provided an auxiliary coil spring 13 to insure that the top will retain'the required resiliency to' obtain the pump effect by merely pressing in said top and'then allowing the same to spring back to its normalstate. Each of the pump-bulbs-13 is fastened to a pad 13, provided with a socket 13", the pad being made of rubber, and the object of the construction described being to render the whole convenient to be aflixed to the legs of the wearer by band 13. I have found it convenient to arrange the pump bulbs o posite to each other near the knee so that th 9 through the pads 12,' as often as desired, by simp y pressing thereon with the knee. Each of-the pumps 13 is supposed to be provided. with suitable valves for con-' trolling the ingress and e ress of the circulating fluid; the details of which valves are not shown, being well known.

Each of the pads 12 comprises a base 12*, in the center of which is secured an S-tube 12* made of metal or hard rubber, to the ends of which are aflixed the ends of the circulation tubes (10, 10 esg.) coiled on the base as shown in Fig. 5. The coiled tubing is provided to prevent the ends of the rubbertubes becoming kinked.

The upper end of the lamp chamber 1 is contracted to a discharge neck or outlet 1 adapted to receive a piece of the flexible tubing 16 to connect therewith a duplex outlet valve 16, a detail of which is shown in Fig. 8. Such valve 16, comprises a body ey may be operated, to cause a circulation'of heated fluid from the heater .isheld in place by bands 12. The S-tube provided in the upper part with necks 16 and 16 constituting duplex outlets, and below with an outlet neck 16, on which is atfixed the upper end of the tubing 16 On the upper-necks 16 are atfixed the lower ends of the outlet tubes 7, 8, and in the body .part 16 is journaled transversely a short shaft 16, provided with a'wing 16; and exterior of the valve casing, the shaft 16 is made with a turn button 16 see Fig. 1, so that the wing 16 may be arranged to one side or the other, for the purpose of causing the discharging heated air to ascend through the tube 7 or the tube 8; and thereby enabling the wearer of my apparatus to cause the heated air to ascend over thatportion of the face which is exposed to'the greatest cold.

To prevent the tubes 7 8, being collapsed and thereby retarding the escape of vitiated air discharged from the lamp, Iprefer to use for such tubes, tubing provided with an inner spiral wire or rib 17, as illustrated in Fig. 9.
