Arthur Joseph Henri Lefebvre, of Montreal, Canada. Safety Device for Razors.
SPECIFICATION forming part of Letters Patent No. 774,257, dated November 8, 1904. Application filed August 21, 1903. Serial No. 170,322. (No model.)

To all whom it may concern:

Be it known that I, Arthur Joseph Henri Lefebvre, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Safety Devices for Razors; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object of the invention is to provide a safety attachment for a razor which will prevent the person shaving himself being accidentally cut and which can be placed upon the razor-blade or removed therefrom without injury to the edge of the razor.

The invention may be said briefly to consist of a guard-plate yieldingly connected to a carrier adapted to be slipped upon the razor-blade and means for yieldingly retaining such guard-plate in close proximity to the edge of the razor and whereby such guard-plate may be moved away from the edge of the razor when the safety device is to be removed from the blade or put thereon.

For full comprehension, however, of this invention reference must be had to the accompanying drawings, forming a part of this specification, in which similar reference characters indicate the same parts, and wherein—

Figure 1 is a side elevation of a razor-blade with a safety device constructed according to this invention. Fig. 2 is a transverse sectional view, enlarged and taken on line A A, Fig. 1, with the guard in contact with the edge of the razor and illustrating particularly the rigid connection or relation between the lips and the guard and carrier on which they are mounted; and Fig. 3 is a similar view taken on line B B, Fig. 1, with the guard moved to a position out of contact with the edge of the blade.

The safety device consists of a trough-section b, corresponding in cross-section to the razor-blade and adapted to be slipped endwise upon the back thereof. The sides c of this trough-section are resilient and normally incline toward one another, with a distance between their outer edges less than the thickness of the razor-blade in order that such trough-section, which constitutes a carrier, will clip the razor-blade and be held firmly in place.

A guard d is preferably hinged, as at e, to the carrier and consists, preferably, of a comb-plate. A pair of lips f and g, respectively, are carried rigidly and in juxtaposition, one, f, by the comb-plate and the other, g, by the carrier, and a bow-spring h is secured at one end, as at i, beneath the attached end of lip f while its opposite end is bent to bear upon the lip g upon the carrier and retain the comb-plate yieldingly in bearing relation with the edge of the razor.

To remove the safety device from a razor-blade, the lips f and g are pinched together against the spring h, thereby displacing the comb-plate from the razor edge, thus enabling the safety device to be slid from the blade without any danger of the edge being damaged by the comb-plate, while the resilient nature of the carrier enables it to be fitted upon almost any form of razor.

What I claim is as follows:

1. In a safety device to be attached to a razor, the combination with a carrier adapted to be carried by the razor-blade, of a guard hinged to said carrier, a rigid lip secured to and carried by said guard and a second rigid lip formed integrally with the carrier, and means yieldingly retaining said lips apart.

2. In a safety device adapted to be attached to a razor, the combination with a carrier adapted to be carried by the razor-blade and consisting of a trough-like device, of a guard consisting of a comb-plate hinged to said carrier, a rigid lip secured to and carried by said guard and a second rigid lip formed integrally with the carrier, and means yieldingly retaining said lips apart.

3. In a safety device to be attached to a razor, the combination with a carrier adapted to be carried by the razor-blade, of a guard hinged to said carrier, a rigid lip secured to and carried by said guard and a second rigid lip formed integrally with the carrier, and a spring between the said lips.

4. In a safety device adapted to be attached to a razor, the combination with a carrier adapted to be carried by the razor-blade and consisting of a trough-like device, of a guard consisting of a comb-plate hinged to said carrier, a rigid lip secured to and carried by said guard and a second rigid lip formed integrally with the carrier, and a spring secured to said guard and bearing upon the lip rigidly upon the carrier.

In testimony whereof I have affixed my signature in presence of two witnesses.

Arthur Joseph Henri Lefebvre.
