N° 532 A.D. 1908

Date of Application, 9th Jan., 1908 Complete Specification Left, 9th July, 1908—Accepted, 5th Nov., 1908 PROVISIONAL SPECIFICATION. Improvements in Safety Razors

I, Sidney Willett of 595, Seven Sisters Road, in the County of London, Engineer, do hereby declare the nature of this invention to be as follows:—

This invention relates to safety razors, and it has for its object to provide improved means whereby the blade, no matter to what extent it may have been ground down (owing to continual sharpening), will always automatically adjust itself against the comb ready fox use in shaving.

To this end, and according to my invention, the blade is carried in a holder, of any suitable construction, which is pivoted, in a spring-controlled frame mounted on an axis supported in lateral lugs formed at the outer end of the comb, and around this axis is coiled the said spring, which also acts to keep the blade in proper angular position relatively to the comb.

The frame is further provided with a thumb-piece, by depressing which the holder and its blade are withdrawn, and can then be readily turned back for purposes of removal of the blade, or for cleaning the comb, or otherwise. A stop (or stops) on the back of the comb, limits the backward movement of the holder and its blade, and supports the latter in a convenient position to enable it to be readily withdrawn, when requisite. A stop (or stops) may also be provided, either on the frame, or on the comb, to prevent the blade accidentally shooting beyond the comb, when restoring said blade to its operative position in engagement with the usual catches on the comb.

Dated this 9th day of January 1908.

I, Sidney Willett, of 595, Seven Sisters Road, in the County of London, Engineer, 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, reference being had to the accompanying drawings and to the letters and figures marked thereon, that is to say:

This invention relates to safety-razors, and it consists in certain improvements in mounting the blade whereby it will always automatically adjust itself against the comb ready for use in shaving, or permit of its being turned back into such a position as to enable it to be readily withdrawn from its clip or holder, when necessary, or to allow of the comb and its adjacent parts to be easily cleaned.

To this end, the blade is carried, as usual, in a clip or holder which, according to my invention, is pivotally mounted in a spring controlled frame which, in its turn, is pivotally mounted at its ends and towards the rear of the comb, the spring of said frame serving to maintain the said blade in proper angular position relatively to the comb.

And in order that my invention may be more readily understood, I will now describe it fully with reference to the accompanying drawings, in which:

Fig 1 is a side elevation of a safety-razor embodying my improvements.

Fig 2 a rear view thereof, and

Fig 3 a view similar to Fig 1, but shewing the position assumed by the razor blade when the spring-controlled frame is retracted.

Figure 4 is a transverse section taken on the line x, x, of Fig 2.

Referring to these drawings, a is the razor blade which is furnished with a mount a¹ adapted to slide into the usual clip or holder b, which latter is pivotally mounted in the frame c; and said mount enables the clip to obtain a firm hold of the razor blade. This frame is pivotally mounted in lugs or arms d, d, depending from opposite ends of the comb d¹, which, in my construction of safety-razor is stationary, and around the axis of this frame c, is coiled a spring c¹, one end of which rests against the comb d¹, whilst its opposite end engages the frame c. The said spring serves, normally, to maintain the blade a in its forward or service position, and for the purpose of retracting the blade the frame c is furnished with a thumb-piece c², by depressing which the frame may be vibrated and the blade a retracted, as shewn in Fig 3. When in this position, the blade may be turned back, as shewn in dotted lines in the aforesaid figure, and so be brought into such a position as to permit of it being readily removed from its clip or holder b, for purposes of stropping. To afford facility for cleaning the comb d¹, and its adjacent parts, pressure is released from the thumb-piece c², so permitting the frame c to resume its normal position, and the blade to fall back against a support d² on the back of the comb, as shewn in dotted lines in Fig 1, and so be out of the way of the fingers of the user. This support also serves as a stop to limit the backward movement of the frame c and therefore of the blade.

The depending lugs or arms d, d, are formed with flats, as shewn at Fig 4, which act as stops against which the lower part of the said frame abuts for the purpose of preventing the blade being shot or projected beyond the comb, when restoring it to its operative position into engagement with the usual catches d³ on the said comb.

It will thus be seen that, unlike certain other safety-razors* the blade is, according to my invention, capable of retraction, also that the support ensures that the blade can never be turned backwards to such an extent as to be dangerous to the user of the appliance; and that the comb instead of being movable is stationary.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is :—

1. A safety-razor having its blade clip or holder pivotally mounted in a spring-controlled frame, and which frame is in turn pivoted to the comb, substantially as and for the purpose described.

2. In a safety-razor, as under Claim 1, the combination of a spring-controlled frame wherein the blade clip or holder is pivotally mounted, a stationary comb formed with depending lugs or arms whereon said frame is pivotally mounted, means for vibrating said frame, and stops for limiting the vibratory movements of said frame, substantially as described.

3. In a safety-razor, as under Claims 1 and 2, a comb provided with a support for the blade when turned back, substantially as described.

4. The improved safety-razor constructed substantially as hereinbefore described with reference to, and as shewn in, the annexed drawings.
