Samuel G. Brosius, of Washington, District of Columbia. Safety-Razor.
No. 809,604. Specification of Letters Patent. Patented Jan. 9, 1906.
Application filed February 21, 1905. Serial No. 246,694

To all whom it may concern:

Be it known that I, Samuel G. Brosius, a citizen of the United States, residing at Washington, District of Columbia, have invented new and useful Improvements in Safety-Razors, of which the following is a specification.

This invention relates to new and useful improvements in safety-razors. Its object is to produce a safety-razor having a single or double edged blade so mounted that the edges of the blade may be reversed for use or the blade removed from the shield and both the blade and the shield cleaned without detaching the blade from its fastenings and so constructed that the blade may be readily removed and again put in place or replaced by another blade. These and other objects are accomplished by the mechanism hereinafter described, and shown in the drawings.

In the accompanying drawings, Figure 1 is a perspective view of a safety-razor, showing the blade in position on the shield ready for shaving. Fig. 2 is a similar view showing the blade raised from the shield. Fig. 3 is a similar view showing the blade swung forward in position ready to be cleaned or removed from its supporting-fork. Fig. 4 is a top plan view showing the fork swung forward and the blade removed, the handle being shown in section below the shield. Fig. 5, 6, and 7 are detail views, hereinafter referred to. Fig. 8 is a sectional detail view of part of the handle, showing the retaining-spring and its coöperating parts. Fig. 9 is a similar view of part of the handle, showing the spring-block and its coöperating parts with the fork swung forward. Figs. 10 and 11 are respectively side and end views of the razor-blade clip, and Fig. 12 is a plan view of the razor-blade.

Like letters of reference refer to like parts throughout the several views in the drawings, wherein—

A indicates the handle, which may be made in the two parts A and A′, fastened together by any suitable means, such as a screw-threaded connection A2, on the upper part A of which handle is supported a shield member c and a razor-supporting member D in the form of a resilient or spring fork, comprising two arms D. A trunnion-bar E, slidably mounted on the handle structure and passing through a slot a therein is held in place by a spring-block F and retaining-spring G, moving in the cavity A3 and bearing against a plug a′. The bar E is flattened, as shown at e, Fig.9, so that when the flat part is turned up against the spring-block F the fork-arms D are held forward. The fork-arms D support the razor-blade H and hold it in place on the rest C′ of the shield c, and being mounted on the bar E the said supporting member and razor-blade H may be moved longitudinally of the handle structure, so as to clear the blade H of the shield c and swing it forward, as shown in Fig. 3, in which position the razor-blade H may be turned to present either of its cutting edges h for shaving or removed from the spring-arms D, as shown in Figs. 3 and 4, and replaced by another blade.

The razor-blade H is adjusted and held in position for shaving on the razor-shield c by a spring B (see Figs. 1, 4, and 5) on the handle or fixed structure and bearing against the forks D of the supporting member, thereby forcing the said supporting member forward and pressing the razor-blade H against the razor-stops c2 of the razor-guard c′. The razor-blade is provided with two cutting edges h, so that one or the other of said edges may be presented for use, and to accomplish this purpose the said blade is held in clips I, provided with cornered bearings I′, mounted in similar bearings d in the fork-arms D and held therein by spring-clips d2, fixed at d′, when in place, (see Fig. 7,) and adapted to yield for reversal of razor-blades. (See Fig. 6.) The clips I have grooves I2 with rounded edges (see Figs. 10 and 11) in which the ends of the razor-blade are held and from which the blade can be readily removed when the spring-fork arms D are pressed apart, as in Fig. 4, push bars J on the fork-arms D being used, if desired, to which pressure is applied by the thumb or fingers, in the direction of the arrow Y, Fig. 4. The cornered bearings I′ serve to hold the clips so that the grooves I2 are parallel, whereby the blade may be readily withdrawn and replaced, and to facilitate turning the said clips knobs i are provided on the outer ends of said clips, (see Figs. 1, 4, and 10,) and the ends of the blades H are curved or beveled, as shown at h′, Fig. 12, to facilitate said removal and replacement.

The operation is as follows: The razor-blade H for action is held in place on the razor-shield c by the spring fork-arms D, which press the blade in the grooves I2, fitting into the notches h2 of the said razor-blade H, and retain it firmly against the rests C′. The fork-arms are controlled by the spring G in the upper part of the handle A, normally retaining the said supporting member in position for the use of the razor-blade. The razor-blade H being mounted on the fork-arms D is automatically adjusted against the razor-stops c2 by the adjusting and controlling spring B acting on the fork-arms D. To release the said razor-blade H from its position on the razor-shield c, the fork D is raised by a movement longitudinally of the handle structure and may then be swung forward, (see Fig. 3,) so that the razor-shield and razor-blade may be cleaned without detaching the blade. To reseat the blade on the said razor-shield, the reverse operation is performed. While the fork-arms D are swung forward, as before described, the razor-blade may be turned in the fork, in conjunction with the clips I, by means of the knobs i or by the blade itself, as indicated by arrows X, so as to present either cutting edge for the purpose of shaving, and while the fork-arms D are in this position they may be spread apart (see Fig. 4) by the push-bars J and the blade removed from the fork-arms. In a reverse manner the blade can then be replaced or another blade substituted. The broken lines show the original position before being pushed apart of the fork-arms and the full lines their positions when pressed apart. To replace the blade or to substitute another, the rounded-edged grooves I2 facilitate ready entrance of the blade H. To hold the grooves I2 of the clips I parallel to each other and to prevent the edges of the blade from being brought in contact with the razor- shield, the bearings I′ of the clips are made cornered (see Figs. 6 and 7) and are held in place by the clamp-springs d.

The invention is not limited to the arrangement or construction shown, as the same may be varied in its several details without departing from the spirit of the invention.
