Description
E. PBRWHT SAFETY RAZOR Filed Jan. 2l, 1953 2 Sheets-Sheet l Cgi 22, 1935l E. PnRWm-Z ZSM? SAFETY RAZOR Filed Jan. 2l, 1953 2 Sheets-Sheet 2 /M/EA/TOE EM u. P/E W/ TZ Patented Oct. 22, 1935 UNITED STATES PATENT OFFICE Application January 21, 1933, Serial No. 652,826 In Latvia February 1, 1932 7 Claims. (Cl. 219-21) This invention relates to heatable safety razors which may be heated in various ways, and has for its object to construct the razors so that they remain heated during the entire shaving period without requiring the supply ci fresh heat.
In order to attain its object the invention employs a heating bolt disposed in the handle of the razor and made of material that is a good heat conductor, such as metal, the bolt iilling the entire handle from one end to the other and being adapted after one heating to keep the razor heated during an entire shaving operation without a new supply of heat.
If the razor is electrically heated, a bolt of this type permits the use of the razor without the dangers resulting from keeping the razor under current during the shaving operation. It suffices to heat the bolt electrically prior to shaving whereupon the current may be switched off without causing the razor heated to approximately to 90 centigrade tocool oi perceptibly during the shaving operation which requires possibly 2 to 3 minutes. For the same reason, the troublesome cord which is particularly inconvenient during shaving, can be dispensed with and the razor fitted at the end of the handle with connecting contacts of the kind hitherto used only in razors in which the blade is moved electrically.
A further object of the invention in case electricity is resorted to for heating the bolt is to provide elastic means on the electric contacts of the heating bolt in order to compel the user to hold the razor during heating so as to prevent accidental superheating.
In its aim to provide a safety razor which after one heating will remain heated for some time without requiring a new heat supply even if the user should lather with cold water, the invention diiers fundamentally from the known art, and the heatable razors proposed by the latter lack essential features of the razor forming the subject matter oi the invention. The known heatable razors have a handle consisting mainly of heat insulating material and provided only at its top with a metal member and built-in means for electrical heating. It is evident that such a metal member which does not ll out the heat insulation of the handle cannot accumulate enough heat to attain the objects of the present invention.
The heating bolt which, according to the invention, lls completely the heat insulation ci the handle may or may not be separable from the razor. In the rst case, the bolt may serve separately for various purposes, such as heating the water for shaving, and the handle of the razor may be made from heat insulating material or consist of a metal body covered with heat insulating material.
Other details of my invention are described in the following specification and shown in the drawings which illustrate several embodiments of the invention and in which Figure 1 is a partial longitudinal section of an electrically heatable safety razor having a heating bolt inserted in its handle; Fig. 2, a View of the heating bolt; Fig. 3, a partial longitudinal section of a heating bolt having a safety razor of usual type inserted therein; Fig. 4, a side View thereof; Fig. 5, a longitudinal section of a heating bolt with in-built elastic means for the automatic separation of the electric contact; and Fig. 6, a plan thereof.
In the construction shown in Fig. l the handle of the razor consists of a metal tube a covered on its outside with a heat insulating sleeve b. At the topof the tube a the guard plate g oi the razor is disposed. Inside the metal tube a. a heating bolt c is arranged which is separately shown in Fig. 2. 'Ihis heating bolt c consists of metal and has at its top end an axial bore and internal thread engaged by the threaded shaft of the clamping plate lc lwhich is pressed against the guard plate g when the bolt c is turned in the tube a. The blade f is inserted between both the plates lc and g.
To effect electric heating the bolt c is provided for any desired length with an inner winding e embedded in the insulating mass d. Current is supplied by means of the conductors e terminating in the base m of the bolt on the contact pins n by means of which the bolt c with or without the razor is inserted in a plug socket until it is heated suihciently. It is then taken out of the socket, and the razor is ready for shaving without requiring connection to a source of current.
Since the bolt remains heated for quite a while, 35
the razor will be hot during the entire shaving operation which will thus be carried out painlessly and smoothly without hurting the skin even if cold water has been used for lathering. The heating bolt c may be used also separately from 4 the razor for heating water for beverages or toilet purposes.
In the construction shown in Figs. 3 and 4 the heating bolt c has a heat insulating outer cover b and a central opening in which the handle p of 4 an ordinary safety razor s is inserted, and the razor can be held in the bolt c by means of a spring, not shown. A heating bolt of this type will attain the objects of the invention even when used in connection with a safety razor of the usual construction.
By way of example, Figs. 5 and 6 show elastic means for the automatic separation of the current connection if the user lets go the heating bolt c during the heating step. In the base m of insulating material and between the contact pins n a casing r is provided containing a displaceable knob t supported by a helical spring u which continually presses the knob t towards the outside. This construction requires that the 6 heating bolt be held and observed during heating by the user, and, therefore, cannot be left in the socket by mistake and damaged.
The same protection could be afforded by shortening the contact pins to such an extent that the heating bolt could not remain in the socket without assistance, or other means could be employed, such as the usual automatic time or heat switches.
Heating of the bolt c may be effected by other means than electricity. The bolt c, for instance, may be solid and heated by means of a heat source of any kind, such as a flame or hot water.
