Description
June 10, 1930. D. B. M LEOD 7 BED WARMING DEVICE Filed Nov. 15, 1926 ma i- INVENTOR V flwmZdZU/Qwd ATTORNEYS Patented June 10, 1930 DONALD B. MCLEOD, QF VANCOUVER, BRITISH COLUMBIA, CANADA BED-WARMING DEVICE Application filed November 15, 1926, Serial No. 148,579, and in Canada February 22, 1926.
This invention relates to a means for heating a bed and is especially designed for the service of patients, who, from defective circulation or otherwise, cannot maintain their natural warmth when in bed and particularly when required to sleep out of doors, as when affected with tubercular disease.
The invention comprises the provision of an air-space beneath an ordinary ventilated 0 bed bottom into which space heated air is delivered from any suitable heating means.
The invention is fully described in the following specification, reference being made to the drawings by which it is accompanied,
in which:
Fig. 1 is a cross section through a bed frame and its bottom having this heating provision, and
Fig. 2 shows to an enlarged scale an alternative heating means in section.
Supported on any bed-frame 2 is a ventilated wire bottom 3. To the outer edges of this bottom 8 a sheet 4 of the such fabric as cotton, asbestos, or the like, is loosely connect ed to sag about six or eight inches below the bottom, thereby forming an air-space 5.
Into this space 5 air, heated by any suitable means, is delivered at 6 to spread under its entire surfaceand permeate the fabric of the base blanket 7 and the bed clothes spread thereon. These bed clothes hold the heated air against free escape and retain it for the benefit of the patient.
This delivery of the heat to the entire under surface of the bottom of the bed constitutes the essential feature of the invention and sets forth the simplest form of its application.
The air, as delivered to the air-space 5, may 40 be heated in any approved manner. In Fig. 1
it is shown as heated in a small, hollow rectangular chamber 15 supported over an oil lamp 16. To this chamber 15 air is admitted through an air flue 17 carried down one end and the heated air is delivered from the other end of the heating chamber through a duct 18 to the space 5 beneath the bottom 3 at either side or at the foot of the bed.
Where electricity is available the heating 50 elements 10, which should be such as will at- 'tain only a moderate temperature at the ordinary voltage, are enclosed in a thin metal casing 11 having open or perforated ends and a downwardly directed tube 12 admitting the external air to the heating elements 10.
This casing 11 with its heating elements is inserted in an aperture in the middle of the sagging sheet 4.
The fresh air is indrawn at 12 and as heated by the elements 10 is delivered from the ends of the casing 11 to the space 5 beneath the bottom 3 to be distributed over the entire length and breadth of the bottom to percolate slowly through it and the bedding.
If the patient desires to reduce the heat without cutting it off altogether, a portion of the base blanket 7 covering the bottom may be uncovered, as at 8, to allow the heated air to escape through the open fabric of the bottom, as shown in Fig. 1, or a closable opening may be otherwise provided in a position convenient of operation by the patient to permit the heated air to escape.
The device is simple and inexpensive to make, is entirely satisfactory in operation and will commend itself not only to invalids but for general use as a means for heating or airing a bed in cold or damp climates.
WVith the most ordinary precautions, there need be no fear of fire as the heating means ids only moderate and is well clear of the bed- I do not desire to be confined to the particular construction or materials as set forth in the foregoing specification, as the same may be varied within the scope of the following claims.
Claims 1. In combination with a bed having a wire bottom, a base blanket laid over the bottom, a fabric secured at its edges to the edges of the bottom and sagging beneath the same to constitute an air space beneath the bottom, and means to deliver heated air into said space, said blanket adapted to be folded back upon itself along an edge to provide an air outlet, the area of which outlet is proportional to the area of the blanket folded back, substantially as shown and described.
2. In combination with a bed having a wire bottom, a base blanket laid over the bottom, a fabric secured at its edges to the edges of the bottom and sagging beneath the same to constitute an air space beneath the bottom, and means to deliver heated air into said space,
said blanket adapted to be folded back upon itself along an edge to provide an air outlet, the area oi; whi'choutlet is proportional to the area of the blanket folded back, said means comprising a thin metal casing located within saiidlepaceandihawtngpertaratexiends,Y
electric heating coils in said casing,' said casing having a downwardly directedair sion tube projecting through said fabric, and means securing said casi'n'gto said fabric.
