HARRISON HURLBERT BOYCE, OF NEW YORK, N. Y., ASSIGNOR TO GILLETTE SAFETY RAZOR COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MAINE.

SAFETY-RAZOR.

Specification of Letters iatent.

Patented July 8, 1913.

Application filed July 17, 1907. Serial No. 3B4L,135.

To all whom it may concern:

Be it known that I, HAIunsoN H. Boron, a citizen of the United States, residing in the city of New York, borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Safetyltazors, of which the fol lowing is a full, clear, and exact specification.

This invention relates to safety razors and has for an object to provide an improved and efficient adj ust-able guard.

My improved guard is easily and quickly adjusted in respect to the cutting edge of the blade and in its preferred form atl'ords ample and sufficient support to the blade inwardly of its cutting edge, uniformly throughout the entire length thereof.

In the drawings accompanying and forming part of this specification a practicable embodiment of a form of my invention is illustrated, it of course being understood that changes of construction and details can be made within the scope of the invention without departing therefrom.

Figure 1 illustrates a longitudinal section of the handle portion of the safety razor and a cross or transverse section of what might be termed the head portion. Fig. 2 is a plan view of the device illustrated in Fig. 1. Fig. 3 is a plan view with the blade and backing removed. Fig. 4 is a side elevation showing the parts disassembled and Fig. 5 is a side elevation showing the parts assembled.

The razor is shown herein made up of a cap or backing 1 against which the 117.01 blade is hold in position by means of the guard The guard is carried by a handle 4 which will be secured to it in some suitable manner as'for instance by means of sol- (let. A screw threaded stud 5 is carried by the cap or backing 1 and is engaged by a screw threaded socket in the end of a locking member rotatably mounted in the handle 4. which is made in,the form of a sleeve. By this means the cap or backing and the guard may be moved one relative to the other. P0 sitioning pins 7 are shown carried by the ea or bachng and adapted to pass through suitable holes in the blade and guard for positioning and holding the blade in proper position. The outer edges of the guard are shown provided with teeth or lingers 8 50 which are located in position to engage the the guard member to thereby cause blade inwardly of its cutting edge uniformly throughout its entire length, and in conjunction with the cap or backing to support the blade along a longitudinal zone inwardly of its cutting edge.

Upon the relative movement of the cap or backing 1. toward the guard the fingers 8 will be pressed into intimate engagement with the blade and upon the continuance or persistence of this movement the fingers will be spread outward thereby increasin the width of the guard relative to the ad accnt cutting edge and in this manner restricting the amount of cut. Upon the reverse movement that of permitting the cap or backing to move away from the guard the fingers will draw inward, thereby decreasing the amount of guard and increasing the working or ellicicnt cutting ed e of the blade. By this means the user ot the razor may regulate the cut and by reducing the amount of exposed cutting edge or clhcient cutting edge reduce the closeness of the shave. If a closer shave however is desired the device will be adjusted to permit the fingers to draw inward and to expose a wider ellicient cutting edge.

What is claimed is:

1. In a safety razor, the combination with a handle portion, a blade retaining plate member of a yielding guard member having its toothed portion arranged at. an outward inclination relative to the plate, means for retaining a blade in position, and means for drawing the plate and guard toward each other to vary the angle of inclination and to thereby cause the guard teeth to move outward relative to the cutting edge of the blade, substantially as described.

ln a safety razor, the combination with a. handle portion and a yielding guard member of substantially bowed formation in cross section, of a plate member extending transversely of the handle portion and having an edge ad jaccnt to an outer portion of the guard member and substantially co-extensive therewith, means for positioning and retaining a blade with its edge adjacent the guard, and means for drawing the guard and plate member toward each other to flex the teeth to more outwardly relative to the cutting edge of the blade, substantially as described.

33. In a safety razor, the combination with limiting or guard member to apply outwardly moving pressure to the described.

4:. In a safety razor, the combination with a handle portion, an outwardly inclined yielding guard member having a toothed edge portion bent to move outward u on pressure being applied, of a plate mem er extending transversely of the handle portion and overlying the guard member, means for securing the blade in position,'and eans guard teeth, substantially as for drawing the plate and guard t ward each other whereby the pressure is applied to the toothed edge of the guard inember for forcing the teeth outwardly relative to the edge of the blade.

5. In a safety razor, the combination with a handle portion, a yielding guard member having an e teeth arranged at an outward inclination so that when pressure is applied to the said part the teeth will be moved transversely outward, of a plate extending transversely of the handle port-ion having its edge arranged adjacent the teeth and'in length coextensive with the guard, means for positioning the blade with its edge adjacent the guard, and means for drawing the plate dge part provided with guard.

toward the guard to deflect the guard teeth 40 outward relative to the blade.

6. In a safety razor, the combination with a blade holding plate and a yielding guard having its toothed edge arranged adjacent the edge of the holding plate and inclined outwardly, of means for causing the toothed [edge of the guard andthe plate to approach each other, whereby the] guard teeth are adjusted outwardly relative to the edge of the plate. Y

7. In a safety razor, the combination with a' blade holding plate, of a blade held'thereagainst, a guard having a yielding toothed edge portion arranged at an outward in-- clination to engage the blade, and means for drawing the guard onto the blade'to force the guard teeth outwardly relative to the v cutting edge of the blade.

, 8. In a safety razor, the combination with a yielding guard member bent at an out-' wardly extending angle having a toothedj edge portion adapted to move outwardly,

upon pressure being applied thereto, of a ade supporting plate member overlying the guard member, a blade supported by the plate member interposed between the same and the guard, and means for moving the blade and its supporting plate to force the "guard teeth outwardly relative to the cut'-' ting edge of the blade.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses.
