Sept. 14, 1937. E. SCHRODER APPARATUS FOR DRYING SAFETY RAZORS Filed Feb. 25, 1935 Jnuenfor:
Patented Sept. 14, 1937 UNITED STATES PATENT OFFICE In Germany 4 Claims.
This invention relates to an electric drying and disinfecting device for safety razors in which only the vertically adjusted head of the apparatus is dried and disinfected, whereas the handle which is in horizontal position is not heated. The electric heating of only the vertically adjusted head requires very simple apparatus and consumes very little current as, viewed from above, this vertically adjusted head looks like an almost line-shaped body under which a short thin heating spiral sufiicient as a heating body is arranged,
the head hanging freely above the same. The head of the safety razor does not come in contact with the device, requires no special support and all its parts are thoroughly flushed by the heated air.
The drying apparatus consists of a box-shaped casing in which a plate is provided which terminates at a distance from the rear wall of the casing. The handle of the safety razor is to be placed in horizontal position on this plate so that the head of the razor carrying the blade is in the gap between the rear edge of the plate and the rear wall of the casing. An electric heating coil or the like in the casing below the gap heats and dries the safety razor situated in the gap. The walls of the casing should preferably extend upward beyond the plate and the upper end of the rear wall be forwardly inclined towards the razor so that the heated air is conducted in such a manner that it thoroughly flushes and quickly dries the razor and the blade.
An electric switch may be provided in the casing below the plate for switching the heating current on and off, the bottom of the casing being preferably constructed as the insulated common base plate for fitting the switch and heating coil parts. Both the casing and particularly the base plate are preferably made of porcelain, artificial 40 horn or some other electricity insulating material. A partition may be provided between the heating spiral and the switch to protect the switch against being heated and to conduct the heated air on to the safety razor.
45 Three embodiments of. the invention are illustrated by way of example in the accompanying drawing in which:
Fig. 1 shows in side elevation partly in longitudinal section the drying apparatus with safety razor resting therein.
Fig. 2 is a top plan view showing the drying apparatus without casing.
Fig. 3 is a perspective view of the apparatus in use.
Fig. 4 shows in side elevation a drying appa- March 8, 1934 ratus provided with brackets for fixing on a wall.
Fig. 5 is a side elevation of a drying apparatus carrying a shaving mirror with a lamp at its lower end.
On a base plate I a switch 2 is mounted which is constructed, for example as a press-button switch, having for example a red button 3 and a black button 4 for effecting the on and off switching. A transverse partition 5 is arranged behind the switch 2 and behind this partition there is a block 6 for accommodating a heating coil 1. The partition 5 and the block 6 and preferably also the base plate I are made in one piece. The current connection between the switch 2 and the coil 7 is effected for example by plates 8.
A box-shaped casing 9 is mounted on the base plate and the upper end IU of the rear wall of the casing is inclined towards the interior of the easing. The casing is closed near its upper end by a top plate l2 broken away at its rear end to form a gap with the rear wall of the casing. The front wall of. the casing 9 has a curved incision l I on its upper edge designed to hold the handle of the safety razor, its head carrying the razor blade lying then in the gap between the rear edge of the top plate l2 and the rear wall of the casing 9. The handle is further securely held between cheeks l3 projecting to the upper side of the top plate l2. The casing 9 has preferably holes I4 near its lower edge to admit the cold air to the heating coil 1.
As shown in Fig. 4, a bracket l5 may be provided on the base plate I, preferably made in one piece therewith, so that the drying apparatus can be fixed on a wall.
In the construction shown in Fig. 5 the rear wall of the casing designated by Hi extends above the side walls and forms a support I! for a preferably curved shaving mirror l8, a lamp l9 being arranged at the lower end of the mirror. A separate switch may be provided for this lamp.
If desired, a time switch may be provided for the heating coil so adjusted that the switched on period is only as long as necessary for completely drying the safety razor. To prevent the possibility of forgetting to switch off the electric coil a small switch lamp can be connected in series with the heating coil, the lamp being extinguished only when the heating coil is switched off.
1. In an electric drying and disinfecting device for safety razors of the type wherein the safety razor is accommodated in a box-shaped casing containing an electric heating device, a horizontal partition in the upper part of said casing extending from the'front wall of the casing to a certain distance from the rear wall of the same and forming a support for the safety razor, a vertical transverse wall under the rear end of said partition forming with the rear Wall of said casing a compartment adapted to accommodate the head end of the safety razor resting on said par- 7 tition, and an electric device on the bottom of said casing to produce a current of hot air ascending in said compartment and flushing the head of said safety razor.
2. An electric drying and disinfecting device,
for safety razors as specified in claim'l, in which the horizontal partition in the casing is slightly inclined relative to the horizontal plane.
3. An electric drying and disinfecting device fo'r'safety razors as specified in claim 1, in which the rear wall of the casing is higher than the front wall thereof and the upper end of this rear wall is forwardly inclined and extends over the compartment formedby the vertical transverse wall and the rear wall of the casing.
4. In an electric drying and disinfecting device for safety razors as specified in claim 1, an electric switch in said casing separated from the' heating device by the vertical transverse wall and adapted to switch the heating current on and off, and a'bottom plate of insulating material in said casing and carrying said switch and.
said heating device.
