The primary object ot my invention is to provide o 'safety guard which will not only prevent deep outs, but whih will smooth the' skin in advance' of the cutting edge7 keeping the skin smooth end dat, and preventing it from being injured as is the case Where the skin can roll up. under the guerd.

"A further object of my invention 4is to provide o safety guard which may easily loe adjusted to tit razors of different sizes.

A still further object of my invention' is to provide a safety guard i'or razors whioh will be vsimple in construction, in manufacture, and eiiieient in use. 3y

'The vorious features of novelty whereby my invention is characterized will herein after bepointed outwitli partieulomit'ge"in the claims; but, for o full understanding@ my invention and of its objects ond' ndvantages, reference may be had to the fol-- lowing detailed description token 1n oounecw tionA with the accompanying drawing,

inits simplest form, my guard comprises o sheet or" spring metal folded upon itself so as to produce n. trougiblike structure whose sides ure of unequal widths, the widtii ot' the trough increasing from the mouth toward the closed end. The Wide side of the trough has a series ofg'ua'rd fingers along its tree edge. The narrow wall of the guard engages with the" side ofthe razor' blade ond serresas a spring to press it against the onposite side. Suitable means are provided or adjusting the blade inond out and `t'or locking it in position. I prefer so to shape the guard that the blade has is on enlarged view of a illustrating the line bearing, the bearing on one side being upon the free edge of the narrow side'of the trough and the two bearings on the other side being near the cutting edge of the Fblede, and near the book.v The lastfmentioned bearing ispreferably afforded by a inciting screw. The guard ngers may be l graduated so es to guide the user in adjustf 'ing the blade in and out, making it-'easier for him to set the blade foro close shove or o medium shove. j l

Referring to the drawing, i represents a strip of spring sheet metal having o series of smallingers, 2, at one of its long edges. The strip is bent along o longitudinal line parallel with the latteredge so as to form o long trough-like member which decreases gradually in Width as themoutfh is reached. In the arrangement shown, the portion of lthe strip which is bent over is in the form of ears, 3, .the ears being long enough to engage et tlnei r free ends n r'zor binde et about' the longitudinal medial line. The ngers are curved, being inclined outwordlgrnot their `leases ond then turning inwardly again toward their free By this arrangement ends.

While detail only a single, preferred torni of my invent-ion, I do not desire to be limited to the particular structural details so illustrated and described; but intend to cover all forms and arrangements which 'lall within the terms employed in the definitions of my invention constituting the appended claims.

I claim:

The l member Ll may conveniently be secured 4to the inner ends of the screws by rivetingl them and therefore, I place the screws oppo l site to the spaces between the ears, 3, so that the riveting may take place after the holder has been bent into shape. r

For locking a blade in its adjusted positions, I provide a thumb screw, 6, which passes through the wide side of the trough so as to engage with the side of the razor near the back thereof.

Fig. 3 most clearly illustrates the manner of adjust-ing a blade and the peculiar conditions which exist during the adjustment and use ot the blade. In this Figure, 7 represents the blade and it will be seen that it is narrower at the back than the width of the trough at this point-L At one side it bears against the vlocking screw, 6, near the back and against the bearing rib er shoulder, S, adjacent to the cutting edge. On the opposite side the free ends of the ears, 3, engage therewith at a point between the locking screw and the 'bearing rib or shoulder, 8.- It will thus be scen't-hat when the locking screw is tightened, placing the spring ears under tension, there is no tendency to' swing a trough-like member widths, guard lin- Consequently, if the locking screw is tightnear the bases of said lingers, the narrow cned a little Itoo much, it can have. no bad side or the trough being resilient and en eitect on the action of the razor in shaving. j gaging with the Vblade at a point between the By shaping the guard fingers so that they points a preach the planeet the cutting edge near wide side of the trough and with the adjusttieir outer ends, they will press upon the ing screw, andan adjust-ing screw carried by skin in advance of the cutting edge and tend the 'bottom of the trough and engaging with to push it forward as the shaving operation the baclr or the blade, the width of the bot-- progresses keeping it taut directly in front j tom or" the 'trough being greater than the of the cutting edge so that the JOrmatiOn or thickness of the back edge of the blade so as wrinkles and consequent cutting ot the 4face l to leave the blade out of engagement' with i prevented. l the narrow side of the trough except ad- To facilitate the in and out adjustment o jacent to the free edge ot' the latter.
