We, William Wallis Twigg, of Harpers Hill Works, Northwood Street, Birmingham, in the County of Warwick, Manufacturer, and Charles Neville Loeb, of 10, New Union Street, Moorfields, in the City of London, Merchant, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement:—
This invention relates to improvements in safety razors.
Heretofore it has been generally assumed that to make thin safety razor blades operative for shaving, it was necessary to clamp them firmly between two surfaces, one the guard and the other a top plate, in such a manner that the blade was supported near its edge. We have found that a very much smaller amount of support and derived without flat or curved clamping plates suffices for making the thinnest blades used, operative for shaving.
In safety razors comprising a comb plate on which stops are provided to determine the position of the edge of the blade, various arrangements of springs have been proposed for pressing the blade against the said stops, for example, it has been proposed to hold the blade between jaws one of which forms the guard or comb provided with stops against which the front edge of the blade is pressed by the other jaw which engages the back of the blade, the said jaws being resiliently or pivotally connected together.
According to the present invention, in a safety razor of the kind comprising a comb plate with stops determining the position of the blade edge and means for pressing the blade against the stops, the said blade is pressed against the stops by a member comprising two or more spring arms passing through slots in the comb plate to which the said member is secured.
In the accompanying drawing, which shows how our said invention may be conveniently and advantageously carried into practice:
As shown in this drawing,
In the particular construction herein described, a flap
To insert a blade, the flap is turned to the position shown in
Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is:—
1. A safety razor of the kind comprising a comb plate with stops determining the position of the blade edge and means for pressing the blade against the stops, wherein the said blade is pressed against the stops by a member. comprising two or more spring arms passing through slots in the comb plate to which the said member is secured, substantially as described.
2. The combination with the razor claimed in Claim 1, of a pivoted flap further ensuring the blade from being raised away from the comb plate.
3. A safety razor constructed as hereinabove described with reference to the accompanying drawing.
