BED-WARMER.

Specification of Letters Patent.

Application filed January 16, 1920. Serial No. 351,746.

To all w 7mm t may concern Be it known that I, JOHN RANDoLrH` the accompanying drawing.

This invention relates to bed-warmers and has for its object to provide a simple, effective bed-warmer of animproved type which will be safe to use under all conditions, being low in first cost, practicallyindestructible and having little or no maintenance cost.

It is an object of the invention to provide a bed-warmer which cannot become overheated and thus cause danger ofV fire, and which will have no exposed heated parts which `might come in contact with .and burn gr cause discomfort to an occupant of the In the accompanying drawings, Figure 1 is an elevation of an ordinary electrical lamp with lamp guard and covering fabric in section; and i Fig. 2 is a top plan view of the lamp and guard with the fabric thereon in section.

As shown in the drawings the improved bed-warmer consists of an ordinary electrical extension cord 1, provided at one end with a plug 2, adapted to be inserted into any convenient and suitable socket to make the electrical connections. At the opposite end the cordis provided with an electrical bulb or lamp 3, of suitable kilowatt capacity, the preferred size being a l-kilowatt lamp. Other sizes of lamps of larger or smaller capacity may, of course, be substituted as may be required or desired by the user.

No novelty is claimed relative to the eX- tension lamp and connections, as the usual form of electrical extension lamp is the preferred device for the purposes of the invention, the lamp being also provided, prefer'- ably, with the usual type of metal lamp guard 4, which serves to protect the bulb from accidental breakage, and also serves a further purpose in connection with the invention, which will presently be described.

The lamp cord as here shown may also be provided with a @ut-Out 5, in addition tothe Patented June 28, 1921.

usual cut-out 6 of the lamp to conveniently f control the lamp to turn the current on or off without displacing the lamp. i

The invention consists in covering the lamp and lamp guard with a porous or openmesh fabric 7 of suitable material, such as cotton or wool flannels, which will readily conduct or permit the heat to pass therethrough, the cover being tied about the lamp guard in any suitable manner as shown for illustrative purposes at 8 and 9 to form a sack or complete cover.

In use the lamp cover will not materially affect the radiation of heat from the lamp, but will act to effectually cover all heated parts of the lamp so that the same `cannot come in direct contact with the bedding or an occupant therein.

The invention has the advantages of cheapness, simplicity, and great effectiveness and may be installed and used without the services of a mechanic or electrician in connection with any electrical wiring system provided with the usual lamp sockets.

In electrical bed warmers of present well known types the heating coils are made of fine copper wires covered with asbestos. When left to run at full heat, these warmers become overheated, thus tending to melt the wires and developing danger of fires. This type ofwarmers are too delicate or fragile and' are frequently in need of repairs` which adds tothe cost of operation and interferes with their use. These disadvantages are fully overcome in the improved warmer of the? present invention, which can be procured and operated at lower cost and without danger of accident.

While the invention is herein described as a bed-warmer, it will be obvious thatv the warmer may be used generally for many non-heat-absorbng fabric arranged about at both ends whereby cords may be passed said guard and lamp but terminating short around said fabric and hold it securely to of the thumb switch to cover parts that bethe guard. u l0 come heated from said lamp, a out out In testimony whereof, I affix my sg1iawhereby the lamp user may outoff the curture.
