This invention relates to that class of safety razors which comprise a thin blade clamped between two plates, namely a lower guard plate and an upper cover plate, the cover plate being connected with the guard plate by a detachable resilient locking support.
The known connections of this type have springs which either vibrate so strongly that they affect the sure guiding and bearing of the cutting edges of the blade against the skin, or they are separate from the handle so that the razor is difficult to assemble, disassemble and clean. Other known safety razors have holders which are movable relatively to the guard plate and depend to a great extend upon the guide being absolutely clean and free from lather and hairs.
The safety razor according to the invention is not open to these objections. The resilient support usually forms with the handle a united whole, capable of being disassembled in exceptional cases, and adapted to carry the cover plate and guard plates so that they are easily removable by means of pins and pin holes. The bearing or saddle-shaped concave part of this support also constitutes the resilient means which in cooperation with a pin provided on the cover plate enable these parts to be reliably held in proper position for use, merely by a relative displacing of the support and plate and afford the appreciable resilient changing of the blade which is of great importance for shaving.
A form of construction of the safety razor according to the invention in which the handle is set at an incline to the blade-holding plates in known manner, is illustrated by way of example in the accompanying drawing in which:—

1. A safety razor, comprising in combination a cover plate provided with a centre pin and two side pins on its under side, a guard plate having apertures registering with and adapted to accommodate said pins, a razor blade with three holes adapted to be clamped between said plates, a neck formed on said centre pin, a flange formed on the end of said neck, a resilient support, a concave top arm of said support adapted to bear at its two ends against the under side of said guard plate and having a slot adapted to accommodate said centre pin, the flange at the end of said centre pin bearing against the side of said resilient arm, and a handle carrying said support and adapted to shift the same relatively to said plates to clamp said blade therebetween.
2. A safety razor as specified in claim 1, in which the handle, the cover plate, the guard plate with the exception of the centre pin are made of a non-metallic, plastic thermo-setting material, such as artificial resin.
3. A safety razor as specified in claim 1, in which the support consists of a metal strip, and the upper arm of said support is bent in chair
4. A safety razor as specified in claim 1, in which the centre pin has a neck of a diameter slightly smaller than the width of the slot in the resilient arm of the support and carries on its lower end the flange of the same diameter as the pin proper.
5. A safety razor as specified in claim 1, in which the guard plate has in its under side a
6. A safety razor as specified in claim 1, in which the resilient support is detachably connected with the handle.
