the blade to be adjusted relatively to the handle. V

In a suitable arrangement for carrying out the invention the lower part of the handle is made fiat and the upper part thereof is made of spring metal of hair pin? or bifurcated shape, either 'withthe limbs integral, or pivoted together with a spring to force them apart, the two ends having lateral projections some ot'whichare sprung into holes, grooves, slots or recesses provided in the studs ot' the upper clamping plate and in lugs or projections from the lower clamping plate. Other holes orthe like are arranged. in the said lugs with which other projections on the limbs of the handle can engage so that the cutting edge of the single edged blade or either edge of the double edged blade may be brought to the correct shaving angle relatively to the handle.

The handle being of flat shape cannot rotate in the hand so that the correct position of the blade on the face can be maintained in a better manner than with the usual round handle. U I p To allowv of stropping the blades, the handle is tormed at its lower end into two clamping parts connected by a hinge joint to receive a razor blade between them, one member or part having studs to pass through the holes in the blade and into holes or recesses in the other member, and the blade being held with its edges parallel to the longitudinal edges of the handle. The two clamping members of the handle are locked together by a head, button or the like on one member snapping into engagement with and between the limbs at the upper part of the handle. This head or button also acts to spread the limbs of the handle when engaged with the blade for shaving so as to lock the handle securely in this position.

The holes or slots in the blades may be made to fit the studs or projections on the upper clamping plate loosely, an eccentric pin pivoted at the centre of one of the clamping plates, fitting into the usual hole at the centre of the blade. Theposition of the cutting edge oredges of'the blade inrelatron to the guard or teeth on the lower clamping plate may be varied by rotating the eccentric pin, say, by means of a screwdriver applied to a nick formed in either end of the said pin. f s V To enable the invention to befully understood I will describe it by reference to the accompanying drawing, in which Figures'l and 2 are elevations at right angles of a safety razor provided with a double edged blade, constructed in accordance with the invention with theblade-in position forshaving. I

-.Figure 2 a section on the line 2 2 Figure 2. I Figure 8 is a view similar to Figurel, with the blade turned relatively to the handle whennot required for use.

Figures 4: and 5 are views corresponding with Figures 1 and 2 but showing the parts separated. i

Figures 6, 7 and 8 are views, respectively,

of the upper clamping plate, a razor blade and the lower clamping plate or guard.

Figure 9 is a view similar to Figure 1, showing the razor provided with a single edgedblade and illustrating the method of adjusting the cutting edge of the blade relatively to the lower clamping plate or guard.

. Figure 10 is a plan view of the arrangement illustrated in Figure 9 and Figure 11 is a section on the line 11--11, Figure 9. i I h 7 Referring to Figures Ito 8, a is the razor blade of theknown form provided with the holes 6 and c, 0. (Z is the upper clamping plate having the usual studs 6, 6 designed to i pass through the holes 0, c of theblade and f is the lower clamping plate or toothed guard having the holes 9, g for the reception of the studs when the bladea is arranged between the said two clamping plates.

h, h are the lugs which 1 form on the clamping plate f and which are provided with the aligned holes 2', 2' and j, j are the holes which I form in the studs e, e and which align with the holes z', 2' when the members 03, at, f are assembled-for use as shown in Figures 1 and 2.

k is the handle of flat form having the bifurcation at its upper end, Z, Z being the projections at the upper ends of the limbs m, m, the said projections extending in opposite directons so that if the said limbs are moved or pressed towards each oflhemthe said pro jections, when the pressure is relieved, can be engaged with aligned holes 6, j to secure the members J, a, 7 in their assembled position as indicated in Figures 1 and 2. To

p ensure the witlidrawalof both projections l from the aligned holes 71, j, a lug f is arranged on the underside of the plate f to form an abutment for either limb m if the projection Z on the other. limb shouldst-ick in tie holes 2', j.

n), n are the additional projections formed on the limb org-m and 0, 0 are the additional holes in the lugs h, h to receive the said-projections so thatthe clamped blade a can be held at the required shaving angle relatively to the handle is as illustrated in Figures 1 and 2. Two holes 0 are shown in each lug h which enables the blade 11 to be secured at the required shaving angle for each of the cutting edges.

p, are the twoclamping portions hinged toget er of which the lower part of the handle Ic is formed, designed, to receive a blade a between them as indicated by the dot and dash lines in Figure 2 for stropping purposes, a", r being the studs on one of the portions of the handle, Which studs engage with the usual holes 0, 0 of the blade and with corresponding holes or recesses s, s in the other portion of the handle. it is the head, button or the like on the member p designed, when in the clamping position, to snap into position between the limbs m, m, it being formed with recesses 'w, to which engage with ribs 0, c on the limbs, as clearly indicated in Figure 2". This head'or button also acts to spread the limbs m, m slightly to lock the handle is securely in osition to the blade a and clamping plates (2 Referring to Figures 9 to 11, which show a safety razor provided with a single edged blade, 10 is the eccentric pin pivoted to one of the clamping plates. In the drawing, it is pivoted to the plate f and fits within the usual central hole 6 of the blade, the other holes a, o thereinbeingmade slightly larger than the studs e, e. y rotatingthe pin w it will be seen that the cutting edgeof the blade he a dv afneedl r retracted with respect to the guard or e'th on the plate f. a: is a nick formed in one end'of the pin w to allow of its rotation-by screw-driver.

1. A safety" razor'comprising upper' andi lower clam-ping plates adapt to hold a blade therebe'tween, said plateshaving lugs depending therefrom, aligned openings formed in said lugs, a handle member, said handle member having projections extending in opposite directions to en age in the aligned openings, and means provided on said plates and "said handle to vary the angle of said plates with respect to the handle.

2.A safety razor, comprising upper and lower clamrin plates adaptedto hold a blade there etween, saidplates having lugs depending therefrom, aligned openings formed in said lugs, a handle member, said handle member having projections extending in opposite directions tojengage in the aligned openings, a second series of openings formed in thelugs depending from said lower plate and a second set of projections on said handle member, said second set of projections beingadapted to cooperate with said second series of openings to vary the angle of said plates with respect to the handle member. i

3. A safety razor comprising upper and lower clamping members", a blade adapted to be held therebetween, said blades having openingstherein to engage with corresponding studs formed on ons of said clam ing members, said openings being slightly larger than said studs to permit turniklgof the blade relatively to the clamping members, an eccentric .pin pivoted to one of said clamping members and enga ed with said blades, and means whereby sald pin may be rotated to vary the position of said blade with-respect to the lower clamping member.
