Application mea April 27,

`This invention relates to lsafetyfraz'ors vand more particularly to a safety razor of thehoe type having a head and handle detachable blades in spaced relation one above the other, and guard means for each blade having projecting teeth with shouldered portions against which thecutting edges of the blades abut, the teeth of one guard being staggered with relation to those of the other, and the handle having a head engaging member for releasably clamping the blades in position and for `removably attaching the handle to the head,

all as will be described more fully hereinafter, and as claimed.

- It is an object of our invention to provide a safetyrazorhaving leading and trailing l blades, the leading blade not only serving to cut the beard but further :serving to smooth the skin in advance of the trailing blade, so that any hair remaining from the shaving of the first bladeis cleanly and closely cut, thereby dispensing with the necessity of shaving twice as with the usual single blade razor.

It is a further obj ect to provide a razor with a plurality of spaced parallel blades, each of which abuts against projecting guard teeth, the guard teeth for one blade being staggered with relation to those of the other blade, so that in the path of the blades no parts of the beard will be left uncut after a single shaving stroke..

Another object is to. provide a razor with spaced parallel blade supporta-one or both of which may be removable for facility of cleaning the razor.

A still further object is t0 provide a razor with a head and handle, and clamping means carried by the handle for slidably and frictionally engaging.` the head to attach the handle thereto when the razor is in use and to firmly hold the blade or blades in position for cutting, but permitting their removal when the razor is disassembled for cleaning.

' Other objects of our` invention will be apparent from the following description and drawings, in which l Figure 1 is a perspective view of the as- 1981. Serial No. 533,334.

sembled razor, part of the handle being broken away, i. 1

Figure 2 is a vertical sectional view, taken along the line 2-2 of Figure 1,

along the line 3-3 of Figure 4,

Figure 4 is a fragmentary view of the razor head, from the rear, showing one`of the side members of the head and the upper or trailing blade guard. 1

Figure 5 is a front view of the upper part 'of the handle with head engaging and blade clamping member thereon,

Figure 6 is a side view of the upper'part of the handle and clamping member,

Figure 7 is a top view of a part of the razor head and upper or trailing guard plate,

Figure 8 is a top view of the slidably received lower or leading guard plate, and

Figure 9 is a top view of one of the razor blades.

The razor head comprises parallel side members 10 and 11 of similar shape and joined together by a, fixed plate 12, the forward edge of which is formed with projecting teeth 13 having upstanding ends 14 defning shoulders against which 'the edge of a blade 15 abuts.

The side members 10 and 11 extend somewhat above the plane of plate 12 and are Figure 3 is a fragmentary sideview taken face as at 16 to receive the projecting ears 17 of a blade and thereby hold it close to the plate 12.

The inner surfaces of the side members are, further, grooved at 18 and 19, in thel plane of plate 12 to receive and guide the body of the blade, these grooves extending beyond the terminations of slots 16.

.The inner surfaces of the side members are also formed with grooves 20 extending from the rear to just short of their forward edges, these grooves being adapted to slidably receive the lower or leading guard plate 21 which is formed, as plate 12, with projecting guard teeth 22 which terminate in shouldered upstanding blade abutments 23. The side members 10 and 11 are forwardly slotted as at 24 for the reception of tabs 17 of the lower or leading blade.

The forward edges of both the side members 10 and 11, and the blade abutments 14 and 23 are bevelled at the same angle, so that the razor may be conveniently held in use and the blades presented to the face at a proper angle.

The handle of the razor terminates at one end in a reduced screw portion, as is shown in the drawings, and upon this is threaded the clamping member 25, having a throat defined by parallel side grooves 26 and 27 whlch receive the parallel side edges defining the reentrant slot 28 in the leading guard plate 21, the toe 29 of the clamping member forcing the lower or leading blade 15 into contact with the teeth 22 and projections 23 of the lower guard plate. The member 25 is provided with additional parallel grooves 30 and 31 at each side thereof for engagement with a slot 32 in the upper or trailin guard plate, the portion of member 25 etween grooves 30 and 31 being cut back as at 33, thereby defining a lip 34 which frictionally engages the upper surface of guard plate 12 and the toe of which abuts against the upper blade 15 to press it firmly into contact with the upstanding portions of the guard teeth 13 The enlarged head 35 on the end of the handle frictionally engages the under side of the lower guard plate to clamp the assembled razor structure in position for use.

Since both the upper and lower blades are of the same structure, these have both been designated by the numeral 15. In use, the lower or leading blade of the razor not only cuts the beard but stretches and smooths the skin in advance of the trailing blade, so that the latter completes the shaving operation. Inasmuch as the guard teeth of the lower assembly obstruct portions of the cutting edge of the blade and thereby prevent a clean and complete shaving of the beard, the guard teeth of the upper assembly are staggered with relation to those of the lower assembly, so that the portions of beard left unshaven by the leading blade are cut by the trailing blade.

From the foregoing it will be apparent.

that we have invented a razor which permits of safe and speedy shaving and, simultaneously, smoothes and stretches the skin in advance of the rearward blade, so that it is unnecessar to useboth hands in shaving and the resu t is comparable to the repetition of the ordinary shaving operation which is undergone for a close, smooth shave.

What we claim is:

1. A safety razor comprising a head having sides, a top and bottom, the top and bottom being formed with outwardly and upwardly extending guard teeth in sets, the individual teeth of which are respectively staggered, blades abutting the said guard teeth, a handle detachably secured to said head and means carried by said handle for holding said blades in abutting relation to said guard teeth.

2. A safety razor comprising vertical side members and a horizontal plate afxed to said side members adjacent their upper edges, the side members being formed with slots flush with the surface of said plate and with inwardly facing ooves extending from the terminations o said slots to the forward edges of said side members, a blade having projecting tabs engageable in the slots, outwardly and upwardly directed teeth formed along the forward edge of said plate and providing abutments for the `cutting edge'of said lade, a second plate received w1th1n grooves in the respective side members, spaced from said first grooves, said side members being additionally slotted from the rear forwardly for the reception of the tabs of a second blade, teeth projecting outwardly and upwardly from the second late to provide abutments for said second blade, a

andle, a clamping member removably mounted thereon and with its side faces grooved to engage in complementary cutout portions in said up er and lower plates, the orward portions ofpsaid clamping member abutting against the rear edges of said lals blades in the assembled razor to hold them firmly against the guard teeth, and means for frictionally engaging said clamping member with the head.

In testimony whereof we affix our signatures.
