Application August 14, 1950, Serial No. 179,202

7 Claims. (Cl. 219--19) This invention relates to a hot foot heater and concerns itself with a device having hinged jaw members which can be separated and retained in open position when in use and which can be closed and supported adjacent a wall in compact form when not in use.

In the present instance, the heater is designed to be heated by electricity but it can readily be adapted to be heated by gas or any other fluid heating medium.

It isan object of this invention to provide a heater which can be closed or folded into compact form with provision for storing the electric cable or gas hose or whatever may be used and supporting the heater in upright position against a wall when not in use.

It is also an object of this invention to provide a heat ray reflector which can be drawn to a position partly without the heater to reflect the heat rays in a lateral direction and under a desk to heat a persons feet.

With these and other objects in view, this invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawing which illustrates a preferred form of this invention and in which similar refercnce numerals refer to similar features in the different views:

Fig. 1 is a perspective view of a heater involving this invention;

Fig. 2 is a sectional view taken upon the line 2-2 of Fig. l looking in the direction of the arrows;

Fig. 3 is a detail sectional view taken upon the line 3--3 of Fig. 2 illustrating a frictional braking means;

Fig. 4 is a detail sectional view taken upon the line 4 4 of Fig. l illustrating holding detents;

Fig. 5 is a top plan view of the heater in heating position with parts broken away; and

Fig. 6 is a vertical sectional view of the heater showf' ing in dotted lines the heater in open position, taken upon the line 6-6 of Fig, 5.

In referring now to the drawing, it will be noted that the heater comprises a lower stationary section 7 and an upper hinge section 8 which is hinged upon pivot studs 9 carried by the lower section 7. These pivot studs have enlarged heads 9a at their outer ends and yielding friction bowed brake plates 10al are positioned between such heads and the upper section 8 in order to maintain the upper section in various open positions.

The lower section 7 has a bottom portion 7a, a rear wall 7b, and side walls 7c which converge substantially to the bottom portion 7a as shown in Fig. 6; the pivot studs 9 aforementioned being located in the side walls 7c adjacent the rear end of the heater. The upper section 8 is provided with a sloping top 8a to correspond with the convergence of the top edges of the sides 7c of the lower section 7 and it is provided with side flanges or walls 8b which telescope over the sides of the lower section. A lifting strap 10 may be secured to the lower end of the upper section for elevating purposes.

In addition to the friction brake applied to the upper 2,708,705 Patented May 17, 1955 section for maintaining the same in any adjusted position, detent means may be provided for more positively maintaining the two sections in closed position or in a predetermined open position. To this end, the side flanges 8b of the upper section may be provided with indented points 11, Fig. 4, adapted for engaging in suitable depressions 13 formed in the side ilanges of the section 7; the radius of the detents 11 being in the same radius as the depressions from the axis of the pivot studs 9.

A reflector plate 14 preferably of polished aluminum is slidably mounted in the lower section. The plate 14 is shown as provided with a slot 15 through which a headed bolt 16 extends and which bolt is secured in the bottom of the lower section. The slot and bolt are designed to allow the plate 14 to be completely slid within the lower section as shown in full lines in Fig. 6, when the device is not in use. However, when in use, the reflector plate 14 may be slid forward beyond the end of the heater as indicated indotted lines in Figs. 5 and 6.

In the present instance, the heater is adapted to be heated by an velectrical coil 17 which is wound upon a rod 18 secured within the lower section as shown-in Fig. 2v. The ends 17a of the coil extend to an insulated'plate 19 supported by an L-shaped bracket 20 secured to theend wall of the lower section as shown in Fig. 6. From the terminal posts 21 upon the insulated plate 19 to which the ends 17a of the coil are fastened, extend connectors 22 which converge to a bushing or socket 23 in the end of the lower section.

An electrical cable 24 connected to the socket 23 is adapted to be connected to the usual wall plug in a dwelling. The rear end of the lower section is provided with supporting feet 25 having legs attached to the rear wall of the lower section which legs serve as a reel upon which the cable 24 can be wound when the device is not in use and put in storage position, and which also serves to space the heater from the wall of a dwelling when in use to prevent the possibility of ires. At a suitable point between the legs 26, there is secured a bracket 27 to the rear end of the heater and this bracket has a bifurcation 28 in its outer end in which the free end of the cable 24 may be anchored as shown in Fig, 5. Thus when not in use, the cable 24 may be wound around the legs 26 and anchored in the bracket 27 avoiding the usual dangling cable.

In Fig. l, the heater is shown in closed position with the cable wrapped around the legs. In such position, it may be lifted and supported upon its legs in a closet or against a wall and occupy very little space.

When it is desired to put the heater into use, it will be positioned with the bottom upon the floor with the feet 25 preferably against a wall in the locality of a wall plug. The cable can then be unwound or can be unwound prior to such positioning and connected to the wall plug. The upper section of the heater can then be elevated as shown in dotted lines in Fig. 6 and the rellector plate 14 withdrawn for reflecting the heat rays in a lateral direction and for protecting the iloor.

It will be appreciated that this heater is well adapted for household service in that it can easily be moved from room to room or from place to place in the vicinity of a source of electrical energy. That when not in use it can be closed, the cable wrapped around its legs and set upon its feet in a closet or against a wall or in any suitable place where it will occupy very little space.

I am aware that many changes may be made and various details of construction varied without departing from the principles of this invention so I do not propose limiting the patent granted otherwise than necessitated by the appended claims.
