HEAT RADIATING DEVICE Filed Nov. 22, 1937 fim g/INVETVTOR.
Patented Mar. 11, 1941 UNITED STATES PATENT OFFICE HEAT RADIATING DEVICE Application November 22, 1937, Serial No. 175,894
3 Claims.
The present invention relates to a heat radiating device adapted to be used primarily to warm a bed prior to retiring and for warming the feet of a sleeping person and maintaining a constant temperature throughout the entire period of use.
My device is especially beneficial to elderly people and those having a poor circulation. An important object of this invention is to provide for the use of standard and stock parts so that replacement of the heating element can easily be made by the user.
Other objects and advantages of my device will become apparent in the course of the following specification:
In the drawing Fig. 1 is a fragmentary perspective view of a bed showing my device thereon; Fig. 2 is a longitudinal, vertical section on the line 22 of Fig. 1.
Fig. 3 is a sectional view on the line 33 of Fig. 2; and Fig. 4 is a perspective view of a modified form of the invention.
In the drawing, the numeral l designates a cylinder, open at both ends, and crimped inward- 1y, adjacent one end as at 2. Located within cylinder l is a smaller cylinder 3, having one end 4 closed and provided with a circular row of apertures 5. Cylinders 1 and 3 are preferably made of metal or other conducting material and are spaced apart by non-conducting lugs 6. A plate of insulation material 4 is placed between closed end 4 of cylinder 3 and stop lugs 1.
Between the pen end of cylinder 3 and crimped portion 2 of the outer cylinder is a plate of insulation material 8 having a circular row of apertures 8 and held between the crimped portion 2 and stop lugs 9. Inwardly disposed on plate 8 is a standard electrical fixture Ill provided with a standard bulb II.
The outer cylinder l is covered with a layer of heat insulation I2 extending slightly beyond its ends and a fabric, protecting covering I3 is provided to cover the entire outer surface of the device. Since the plate 8 will have to be removed to replace bulb II, it is necessary to have a separ rate fabric cover l4 adjacent the same, said cover being clamped by a split wire l5. A thermostat l6 insures that a constant temperature will be maintained during the time the device is plugged in as in Fig. 1.
Fig. 4 shows a modified form of the invention wherein handle I! is provided and the light cord extends thru hollow shaft It so that the device may be adapted for many commercial uses.
In the use of my device, the same is placed on the bed sheet and rolled over the same to warm the surface before retiring. The device when used to warm the feet is placed as in Fig. 1, and a constant warming effect may be maintained as long as the device is plugged in, due to the thermostat IS. The size of the bulb l I, may be varied to suit different conditions.
From the foregoing it may be seen that I have provided a simple, practical device, made principally of standard or stock parts and adapted to greatly enhance the sleeping comfort of a person using the same.
I reserve the right to make numerous changes in the size, shape and arrangement of the parts and to substitute equivalents within the scope of the invention.
What I claim is: I
1. In a device of the character described, an outer shell open at both ends, an inner shell symmetrically spaced within the outer shell, apertured end closure means yieldably retained within the outer shell, a heating means supported on one end closure means and projecting into the inner shell, said outer shell being cylindrical, and handle means adapting the device for use as a heat roller.
2. In a device of the character described, a cylindrical metal shell open at both ends and having inwardly directed crimp means adjacent each end, an inner metallic shell spaced inwardly from the outer shell by insulating legs and including one integral and perforated end closure,
an insulating shell encasing the outer metal shell,
an insulating ring abutting the inner shell end closure and the inner portion of the crimp means at the adjacent end of the device, and an insulating carrier plate yieldably retained within the other end crimp means and supporting a heating means projecting into the inner shell and a thermostatic control for said heating means.
3. In a device of the character described, a cylindrical metal shell open at both ends and having inwardly directed crimp means adjacent each end, an inner metallic shell spaced inwardly from the outer shell by insulating legs and including one integral and perforated end closure, an insulating shell encasing the outer metal shell, an insulating ring abutting the inner shell end closure and the inner portion of the crimp means at the adjacent end of the device, an insulating carrier plate yieldably retained within the other end crimp means and supporting a heating means projecting into the inner shell and a thermostatic control for said heating means, and a fabric overall casing including a removable cover portion disposed at the heating means bearing end of the device.
