head 21 of the screw. This makes a simple swivel connection between the screw and '5 blade-presser, and preferably the pin 20 is rigid with'respect to the blade-presser, so that there is a large wearing surface between the screw and the pin.

The plates 10 and 11 are resilient, and tend to approach each other so that when applied to a razor blade as indicated their lower arts conform to and clamp the blade and 0 'er a slight resistance to the advance of the blade in the guard by the ad usting screw 21.

ihe guard is placed on the razor blade by an endwise thrust, the insertion of the blade being facilitated by the outwardly turned lips 18 at the ends of the plate 11.

It will be seen. that the cheeks 12 and 13 form an effective guide for the blade-presser v and prevent its rotating when the screw is rotated, and for this reason the width of the blade-presser is such that it fits neatly in the space between the guide cheeks 12 and 13.

In order to insure that the pin 20 will be rigid with the blade-presser when riveted, if desired, the countersunk opening in the blade-presser may be notched in a well understood manner. Y

After adjusting the guard to a blade, it may be removed therefrom at any time, replaced or reversed without need of further adjustment, there being in screw or other fastenings to hold the guard on the blade, and but one adjusting screw/Which it is new necessary to touch when removing or rep c:-' ing the guard.

If desired the screw threads in the sleeve 16 may be formed in the dies which form the plates 10 and 11, so that the threads are formed by the same operationthat forms the plates, but if it is preferred not to form the threads in this way they may be cut in the sleeve after the plates 10 and 11 have been riveted together.

The upper edges of the plates I0 and 11 do not extend as high as the back of the razor blade and as the neck at which the plates are connected is narrow, no impediment is oifered'to a person shaving around the nose, ears, and upper lip.

It is understood that the embodiment of the invention described above is only one of the many forms or embodiments the invention may take, and I do not wish to be limited in the practice of my invention, nor in my claims, to the particular embodiment set forth.

What I claim is 1. A safety guard for razor blades comprising a pair of elongated plates having a nari ow connection therebetween, said plates having a neck near said. connection with 55 substantially parallel sides, a presser strip guided in said neck and between the sides thereof and adapted to engage at two separated points the back of a razor blade to which the guard is applied, said plates having converging portions beyond said neck adapted to engage the sides of the razor blade, and a single adjusting screw between said separated points mounted in said narrow connection and imparting the adjusting force through said presser strip to the razor blade.

2. A safety guard for a razor blade consisting of two plates adapted to engage the opposite sides of the razor blade, a bladepresser mounted between said plates, an ad justing member for moving said bladepresser toward the razor blade, said plates having oppositely disposed offset portions forming a guide engaging said adjusting means.

' 3. A safety guard for a razor blade consisting of two plates adapted to engage the opposite sides of the razor blade, 9. bladepresser mounted between said plates, a screw for adjusting said blade presser toward the razor blade, said .plates having meeting flanges and each having an oflset portion, said ofi'set Portion being oppositely dis posed and forming a guide sleeve engaging opposite sides of said screw.

4. A safety guard for a razor blade consisting of two plates adapted to engage the opposite sidesof the razor blade, a bladepresser mounted between said plates, a screw for adjusting said blade presser toward the razor blade, said plates having oppositely disposed ofiset portions forming a guide sleeve engaging said screw, and a swivel connection between said screw and said blade-pressen :i i

5. A safety guard for a razor blade having means for engaging the sides offhe razor blade, a blade-presser for engagin "the back edge-of the razor blade, a screw mounted in said'guard for adjusting said blade-presser toward the blade, said screw having a bore passing therethrough, and a pin connected with said b1ade-presser and passing through i said bore to retain-said screw in connection with said blade-presser.

6. A safety guard for a razor blade having means for engaging the sides of the razor blade, a blade-presser for engaging'the back edge of the razor blade, a screw mounted in said guard for adjusting said blade presser toward the blade, said screw having a bore passing therethrough, and a pin connected with said blade-presser and passing through said bore to retain said screw in connection with said blade-presser, said pin forminga swivel pin and having one extremity riveted to said blade-presser and the other extrem- 1ty riveted over the end of said screw.

A safety guard for razor blades comprising a pair of connected plates, said messes I e plates having eppositely disposed parts forming a neck with substantially-parallel sides and having converging blade engaging members beyond said neck for engaging the .5 razor blade to which the guard is applied, a single adjusting screw having a threaded connecision "withssid guard, and a resilient presser strip guided between the sides 03": said neck toward and away from the razor 10 blade and having a swiveied ccnnection near its middle point with said screw and imparting the forcefrom said screw to the razor blade at two widely sepsrebedpoints.

'8. Asafety guard for razor blades con- 15 \sisting of two connected plates adapted to.

receive the razor blade therebetween, a singie adjusting screw mounted in said guard, and a spring in the ierm of a presser strip connected with said screw near the middle point or said presser strip, and adapted to 20 receive a force exerted through said adjusting screw and impart the same through said presser strip to the razor blade at two separeted points in force the blade outwardly, said connect/ed plates having elongated ere 25 tensions converging toward each other, com farming to the shape of the razor blade and resisting the outward adjusting movement of the blade by said adjusting screw.

In testimony whereof I have hereunto set 3 my hand in presence of two subscribing witmesses.
