N° 3936 A.D. 1912
Date of Application, 16th Feb., 1912 Complete Specification Left, 15th Aug., 1912—Accepted, 9th Jan., 1913 PROVISIONAL SPECIFICATION. Improvements in Safety Razors

We, William Wallis Twiggs, 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 our invention to be as follows:—

This invention relates to safety razors of the kind wherein two opposite edges of the blade are exposed and provided with combs ready for use.

According to the present invention, the frame bearing the razor-blade is pivotally mounted on the handle, so as to permit of its being rocked through a suitable angle in either direction, in order to enable the blade in use for the time being to be brought into the most convenient position for shaving.

For this purpose, the comb-plate, on which the blade is secured, may be provided with two legs which are pivoted to the corresponding legs on a bar preferably screwed to the handle. These legs may be advantageously arranged to form stops which abut, e.g., against the comb-plate or bar and limit the angle through which the frame can be turned.

The razor-blade may be advantageously secured to the comb-plate by means of one or more headed studs projecting from the surface of said plate and extending through holes in the blade and in a cover-plate resting on the top of said blade, the holes in the cover-plate being provided with lateral slots adapted to receive the stems of the studs beneath the heads thereof. By moving the cover-plate laterally so as to bring said slots into engagement with said stems, the cover-plate and razor-blade can be securely held in position. By moving the cover-plate in the opposite direction, so as to bring the heads of the studs into register with the holes in the cover-plate, the said plate and the blade can be readily removed.

COMPLETE SPECIFICATION. Improvements in Safety Razors

We, Wlliam 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 a safety razor comprising a double edged blade, of the kind wherein the blade is set at an angle other than a right angle relatively to the handle. In razors of this kind it has been proposed to provide universal or other joints in the handle.

According to the present invention the ends of a bar fixed to the handle are turned up to form brackets and, correspondingly, the ends of the comb-plate are turned down to form lugs which are pivotally joined to the said brackets.

There is thus provided a simple and inexpensive construction permitting the comb-plate and the blade to rock on the said bar.

The blade is secured to the comb-plate by a cover plate attached to the comb plate by means of headed studs extending through key-hole shaped slots. For this purpose the use of a single stud and slot has already become known but this necessitates the provision of supplementary means to prevent the blade from turning about the single stud. Such supplementary means for preventing turning are unnecessary when a plurality of studs are used.

In the accompanying drawing:—

Figure 1 is a front view of the improved safety razor, and

Figure 2 is a side view thereof.

Figure 3 is a plan view of a cover plate, shown separately.

Figure 4 shows a section on the line x—x, Figure 1 drawn to an enlarged scale, and

Figure 5 shows a section on the line y—y, Figure 2, also drawn to an enlarged scale.

As shown in this drawing, a is a handle to which a bar b is detachably secured by a screw c but it may be fixed by rivetting. The ends of the bar b are bent upwardly to form legs or brackets d. By means of pivots e the said brackets d support corresponding legs or lugs f formed on a comb plate g. The comb plate to which a blade can be secured, as hereinafter described, can rock on the pivots through an angle limited by the engagement of the comb plate against the inclined surfaces h on the brackets d which thus form stops or abutments. It is however obvious that stops or abutments may be formed on the lugs f to engage the bar b to limit the movement of the said comb plate.

The rivets or other members forming the pivots e are made to provide sufficient frictional resistance to the turning of the comb plate to retain the latter during ordinary use of the razor, in any position to which it has been brought.

A razor blade i is advantageously secured to the comb plate g by means of headed studs j projecting from the surface of this plate and extending through key-hole shaped slots k in a cover plate l. The blade i has holes therein through which the studs j are passed and the cover plate is then put in position on the studs to clamp the blade to the comb plate. By moving the cover plate to the left from the position in which it is shown in Figure 1 the enlarged parts of the slots k are brought around the studs j and thus allow the plate l to be lifted off. When this plate is brought back to the position shown in Figure 1 the edges of the narrow parts of the slots engage beneath the shoulders under the heads of the studs j. The engaging parts of the cover plate l and studs j may be sloped or bevelled so as to have a wedging action as the plate is brought into position to hold the blade on the comb plate.

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. In a safety razor of the kind comprising a double edged blade the inclination of which relatively to the handle, can be adjusted, the provision of brackets on a bar carried by the handle and lugs on the comb-plate, respectively, the said brackets and lugs being pivotally joined together, in combination with the provision of a cover plate removably attached to the comb plate by a plurality of headed studs passing through key-hole shaped slots in the said cover plate.

2. A safety razor constructed substantially as described with reference to the accompanying drawing.
