BLANKET WARMER.

Application med April 18, 1927. Serial No. 184,807.

This invention relatesto improvements in blanket warmers and the object of the invention is to provide a simple, neat and durable device of this description in the form of a heater particularly adapted for heating blankets and retaining them heated ready for use in ambulances or the like, so that when a call for an ambulance is received blankets and the like required will be automatically heated on the way to answer the call.

A further object is to provide a device of this description for use with ambulances, so constructed that the amount of electric current consumed to keep the contents warm will be reduced to a minimum and which is preferably thermostatically controlled.

With these and other objects hereinafter more fullyreferred to, the invention comprises a box or container with insulated walls and an insulated lid and means for supplying an electric current to heat the interior thereof.

Referring now to the drawings, in which like characters of reference indicate corresponding parts in each figure,

Figure 1 is a perspective view of the heater.

Figure 2 is a. longitudinal section.

Figure 3 is a. cross section.

Figure 4 is a diagrammatic view of the electric wiring;

Referring more particularly to the drawings, in which a preferred example. of my invention is disclosed, A designates the container or box constituting the warmer as a whole, preferably constructed of metal with inside walls 11 spaced from the outside walls or casing 12 to provide a space 13 therebetween which may be filled with any suitable insulated material such as asbestos, cork, mineral woolor the like, as indicated by the numeral 14.

The lid 15 of the box is hinged at 16 and equipped for carrying by a handle of flexible material 17 and is adapted to be secured on the box by stud clips 18.

In the end of the box is a plug 19 connected with the outside and inside circuits.

For heating the box, I provide a bar member 20 supported on brackets 21 adjacent the bottom of the box and bolted into the ends of the box by the bolts or screws 22 (see Figure 2).

The curved baffle plate 23 (see Figure 3) is supported on legs 24 to clear the element,

while a wire cage or basket 25, adapted to hold the blankets or the like 26, is kept clear of the baffle plate by side brackets 27.

In Figure 4 the heating circuit is controlled by a thermostat 28 operating a switch 29 and an emergency fuse 30. A suitable cover 30 is provided to house the thermostat and switch.

The circuit comprises the lead 31, in which is the fuse 30, a lead 32, in which is a thermostat 28 operating the switch 29 comprising the contact points 33 and 34. The thermostat 28 is affected through the resistance coil 35 in the lead 36 to heating element 20 and the return wire 37, thereby, causing the contact points to be normally retained in engagement with one another and on a predetermined ten'iperature being reached to be operated by the thermostat to separate and open the circuit.

From the foregoing it will be seen that I have provided a handy, inexpensive and eflicinently operating device essentially adapted for use with hospital ambulances and whereby, without delay and during the actual travel of the vehicle, blankets or the like are heated to a predetermined temperature to be ready on the arrival of the ambulance at its destination for use.

It may also be mentioned that the warmer can be attached to an ordinary electric light socket, the same as an electric iron, and in this way blankets are heated to any temperature desired and are ready in the office or anywhere convenient to the ambulance, night or day, so that when a call is received all that is necessary is to pull out the plug and place the warmer in the ambulance. The warmer, being insulated, will retain an even temperature for a considerable time. The automatic operation of the thermostat will keep the temperature within the casing at a predetermined degree.

As many changes could be made in the above construction, and many apparently widely different embodiments of my inven-- tion, within the scope of the claims, constructed Without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. A blanket warmer for ambulances or the like, comprising a casing, a hinged lid for the casing, an inner casing spaced from the outer'casing insulating material between the casings, a metal ba'sket suitably supported within the inner casing, a heating elementibeneath the basket and a baffie plate between the heating element-and the bottom of the basket, and thereinostat-controlled plate suitably supported in the casing in spaced relationship above-the heating element, a clothes-carrying basket bracket-supported in the casing in spaced relationship to the heatinggelement, and means for supplying an electric current totlie heating 'ele ment,fand thermostatic control for saidcurrent whereby, on a predetermined tempera- T ture being reached Within the casing; the

circuit is automatically opened. 7

In y vitne ss whereof I' haye hereunto set my hand. V a
