blade universally known as the Gillette and all other blades of a similar patternmay be used therewith. Further objects are to provide simple adjustable means whereby a coarse or a line shave may be made by slightly manipulating the clamping arrangement.

With the above and other objects in view which will appear as the description proceeds, the invention consists of the novel construction, adaptation, combination and arrangement of parts hereinafter described and claimed. These objects are accomplished by devices illustrated in the accompanying drawings; wherein razor in a partly open position;

Fig. 2 is a view in longitudinal section taken substantially on a broken line 2, 2 of Fig. 1;

Fig.` 3 is a somewhat similar view showing tl e parts in an unclamped position;

Fig. 4 is a view in transverse section taken on a broken line 4,4 of Fig. V1; and

Fig. 5 is a view in perspective showing the clamping members in their relative position with a blade interposed therebetween.

Referring to the drawings throughout which like reference numerals Adesignate likeV parts, the numeral 5 indicates the handle that is pivoted at 6 to a shank member 7. Said shank member is flared at its outer end to form a relatively wide head portion 8 that is,

hollow ground on its underside, asvat 9, to provide resilient or spring means and which is provided with sharp edges 10 for reasons hereinafter setV forth. e Y e The shank head -8 is provided with a pair or" slots 11 that are spaced apart in conformity with a pair of holes `12 that are ordinarily provided in a Gillette or similar razor blade here designated by the numeral 13. vSaid blade is placed against the .underside or concave face oi the shank head with said holes in registry with said slots in the assembly ofthe E device as will be understood. Y A

Figure 1 is a view in elevation showing the A guard member 14 is next vplaced against 'theI underside of the blade Said guard is provided with a pairof clamp fingers `15 that arefpunched out from the metal thereof and are disposed inspaced relationv correspondingwith, that of the slots` l"11 and `holes 12 so thatwhen said guard is placed in position against said Vblade said fingers will project through said holes andslots as clearly shown in thedrawings. j j

The guard member 14 is provided with the lusual delectedteeth 16 on both edges and a spring tongue 17 extends from one end of the guard andin the same direction as the devilected endi'iportions of the clamp iingersl.

A lip 18 is provided on the end of said spring tongue, and thus, when said clamp lingers are passed through the holes 12 and slots 11 in the assembly of the device, said `lip is used for pulling said guard member back until the device is clamped or locked in the completely assembled position as shown in Fig. 2.

It will be obvious that the device may be readily taken-apart for renewal-of the blade 13 bypushing backward onthe lip 18 until the clamp lingers 15 are in position to pass through the slots 11 and holes 12 as shown in Fig. 3. In the assembled position the spring pressure of the concave shank head 8 on the one side and the pressure of the guard member caused by the spring tongue 17 on the other side will retain the blade clamped securely therebetween. In Fig. 2 the blade is shown clamped in the ultimate or tight position for use in shaving the face close.

In cases where a close or iinished shave is not desired, as vfor instance when shaving a heavy or long beard, I have provided means for clamping the bladewithV less spring pressure. Said means comprises a countersunk groove 19 in the concave side of the shank head 8 extending from each of the slots 11. j

When the dellected end portions of the clamp fingers 15 rest in said grooves it will be evident that the spring pressure will not be so great and the resilient concave shank head will therefore be slightly contracted thus exposing a larger portion of the cutting edges of the blade for engagement with the beard.

It willnow be apparent that `have prolil vided a safety razor having a handle Which serves as a shield for the cutting end of the razor in the closed position, and embodying means whereby the blade may be readily installed or removed together with adjustable means whereby either a close or a coarse shave may be made by making a slight adjustment of the clamping devices.

Having thus described my invention, it being understood that minor changes may be resorted to in its construction Without departing :from its scope and spirit, what I caim and desire to secure by Letters Patent of the United States is A safety razor comprising a handle, a shank ineinb'er pivoted to fold Within the handle, a relatively Wide spring head for said shank member having a pair of spaced slots therethrough', a groove extending from each ot said slots, a razor blade having a pair of spaced holes in registry with the slots, a guard member, a spring tongue for said memb'er, a lip on the end of Said tongue, and a `pair of clamp fingers spaced to pass through said holes and to resiliently clamp through said slots in engagement with either the outer Jface of the shank head or the grooves therein.

In testimony whereof I atiX my signature.

RICHARD D. BAKER.
