Application April 29, 1947, Serial No. 744,639
This invention relateshto. a, por able heater adapted for use in a bedroom or hospital.
It is an object of the present invention to provide a portable heater which will :deliver' a'current of air over the surface of a person to warm the same and which has its source of powerfrom a readily available wall socket and wherein the heater can be adapted. by, the applization of delivery tubes and a 'cas'ing'to' deliver heat over a concentrated area of the bo'dyof a person. Itis another object of the-present invention to provide in a portable heater for bedroom and hospital use a thermostatic control device for maintaining an even temperature of the heated air which is delivered by the heater.
Other objects of the present invention are to provide a portable heater which is of simple construction, of light weight, inexpensive to manufacture and efficient in operation.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a side elevational view of the heater without the external parts connected to the same.
Fig. 2 is an end elevational view of the heater.
Fig. 3 is an enlarged longitudinal cross-sectional view taken on line 3-3 of Fig. 2.
Fig. 4 is a fragmentary detail view looking in plan upon a slide adapted to be extended from the end of the heater to support a blanket or the like when the heater is used in a bed.
Fig. 5 is a tranverse cross-sectional view taken on line 5-5 of Fig. 3.
Fig. 6 is a transverse cross-sectional view taken on line 6-6 of Fig. 3.
Fig. '7 is a fragmentary detail view showing the connection of one of the heated air tubes with the heater box.
Fig. 8 is a perspective view of a casing adapted to be connected about the limb of a person.
Fig. 9 is a fragmentary end elevational view of the heater box and showing the screened outlet, the view being taken on line 9-9 of Fig. 7.
Fig. 9a is a fragmentary top plan view of a spring retainer element adapted to be extended over a closure plate for an opening in one of the tubes extending from the heater box.
Fig. 10 is a wiring diagram of the electric circuit.
Fig. 11 is a top plan view of the entire arrangement assembled with the casing fixed to a limb of a person.
Fig. 12 is an illustrative view showing the ,3 Claims. (01.219-39) 2 heater box located in a bed with the sheet supports extended and with the person's feet located at opposite sides of the heater box.
Referring now to the figures, l5 represents a box having a central tube It extending therethrough and beyond the opposite ends of the box. About the extended end of the tube l6 there is fixed a ring I! by means of bolts l3 extending through a flange 19 thereof. This ring I! serves to secure-a screen 2| over the end of the tube I6. Thereis one of these screens at each end of the tube l6.
Within the tube I6 there is mounted on a bracket 22, an electric motor 23 having a fan 24. This fan operates to draw air into the heater tube It to cause its movement over a heater element 25 in the form of a lamp and mounted upon a bracket 26 extending upwardly from the bottom of the tube I6. Extending out of the casing l5 are wires 260 which have a plug 21 for attaching the heater to a wall receptacle 28.
The top of the casing has a handle 29 by which the heater can be transported. Also on the top of the casing are slide elements 3| adapted to extend respectively from opposite ends of the box to support a blanket or sheet as illustrated in Fig, 12. The slide 3| is held in its adjusted position by a screw 32.
Adapted to be fitted over the rings H are tubes 33 and 34. These tubes may extend to a flexible casing 35 adapted to be wrapped at its ends as indicated at 36 about a limb 31. The casing 35 is formed of a single piece with the edges connected together by a lacing 38. In the sides of the casing are clamping rings 39 for fixing the tubes 33 and 34 therewith. The heated air will pass through the casing 35 and over the surface of the limb 31. The air is returned through the tube 34. The tubes 33 and 34 ar made fixed with the rings I1 by a clamping ring 4| and can be readily released to permit the removal of the tubes for use of the heater without the same. Within the tube 33 there may be inserted a thermal element 42 having wires 43 which connect with a gaug 44 mounted on the side of the casing I5. The temperature of the outgoing air can at all times be observed. Within the tube 34 is a notch 45 over which there can be extended a. closure plate to be secured thereon by a spring clip 46, Fig. 9.
Referring now to Fig. 12, it will be noted that the heater is being used to warm a bed and that the tubes 33 and 34 are disconnected therefrom. The slides 3| are extended and a sheet 41 is extended over the same and over the casing l5.
The person's leg as indicated at 48 can extend to the side of the casing l5. Heated air will be blown upwardly over the body of the patient.
It should now be apparent that there has been provided a heater which can be readily adapted for use in warming a bed and which with the addition thereto of auxiliary equipment can be adapted to deliver a flow of heated air about a concentrated area on a person's body.
WhileWarious-changes may bemade in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
I claim:
l. A portable heater comprising a-cliei r'ig, a central tube extending longitudinally, through the casing, an electric fan mounted within the central tube, a heating element mounted -in the central tube in advance of the electric fan, and said central tube extendingybeyond-gthe tenda of the casing, screensover-the ends of :thetube; :rlng
elements surrounding the extended ends-otthe tube gand connectedto the casing, tubes fitted upon the ring elements at theend of the-central tube, said tubes serving as an voutlet passage for the heated air after it has passed over a concentrated area of a body surface, a fleetiblewcasjng connected between the outlet and return tubes -disposed in a bed whereby the sheet will be regtained-in mposition removed from the inlet and and adapted to be laced to the body beingheated 3 in such a -manner as to prevent escapegof the outlet ends of the tube.
