SAFETY-RAZOR.

Specification of Letters Patent. Patented Dec. 31, 1912.

Application filed January 5, 1912. Serial No. 669,561:

To all whom it mayconoern:

-Be it known that I, SAMUEL ADLER, a sub-.

ject. of-the Emperor of Austria-Hungary, 'Tdfing at 110 Dresdnerstrasse, in the city of Vienna, ,Empire of Austria-Hungary,, have invented certain new and useful Improvements in Safety-Razors, of which .the fol- This invention'relates to ashaving razor which may be adjustedto obtain-a fine or dle of particular shape and use mechanism tor the guard plate which was much .too complicated to be used with shaving razors. Further, this arrangement could not be used for shaving razors in which the blade is clamped between a back plate and the protective comb. Allthese disadvantages are avoided in the shaving razor according to the present invention, which is characterized byits simplicity and reliable working and also allows any desired 'handle to be used. This is obtained in that each guard comb is pivoted on and adjustable relative. to the guard plate so that the guard comb may be adjusted relatively to the blade without affect-ing'the latter to obtain the desired fineness of cut.

One method of construction according to thelpresent invention is illustrated by way of example in the accompanying drawings in which Figure 1 shows'the razor partly in section and partly in elevation. Fig. 2 is an end elevationalview and Figs. 3 and 4 are sections through-theguard plate at various adjustments of the guard comb. Fig. 5 shows the guard plate with one guard comb. Fig. 6 shows a perspective view of the guard comb alone,-and Fig. 7 is a detail perspective view of the blade adjusting device.

The blade a of the razor is clamped be tween a back plate d and a guard plat-e f. The guard plate 7 is provided along each longitudinal side with a guard comb g in the known manner, the teeth of which guard comb after the blade has been clamped, lie against the cutting edges and project slightly beyond these (Figs. 1 and 2).

In order to correctly adjust the guard plate f and the blade a relatively to the pass through perforations-in the blade and guard comb. The handle consists of the spring clip 2', theends of which lying opposite the guard plate ofthe razor are forked and are adapted to engage the guide pins h. The ends of the clip are also formed so that they act as pressure members for the purtweenthe back plate and theguard plate. Owing to the elasticityof the clip in its position of use it presses the guard plate against the blade by reason of its thumbshaped ends and holds this in the cutting position. I

Each guard comb g is arranged as an independent part and is pivotally mounted by means of pins 7a (Figs. 1 to 5) on-the ries an arm Z which abuts against the middle of the guard plate. this guard plate a screw spindlen'i is mounted upon which isarranged a nut or knob n provided with a rounded end. The nut n 0 in which the narrowed ends of the arms Z of the guard comb g engage. Bydisposing the nut n along the screw spindle m the guard comb '9' 1s turned by means of the arms Z and is displaced relatively to the blade a for the purpose of adjusting the fineness of out. In this manner, therefore, the displacing of the guard comb does not afi'ect the blade so that this may always be securely clamped between the back plate and the guard plate.

Any desired liding member moving up and down may be substituted for the nut guard plate must be connected to it by intermediate means so that by displacing the sliding member the guard comb is swung about its pivots.

I claim I 1. In a safety razor, the combination of a guard-plate; a back plate; a blade interposed between said guard and back plates; a guard comb pivotally mounted on. said guard plate and having a projecting portion; a guard-comb ad usting device comprising a member mounted on the guard plate, a nut adjustably mounted on said back plate cl, the back plated is provided with two pins h having small heads which pose of clamping the blade securely be-.

guard plate f. Each comb member 9 care In the. middle of is further provided with an annular groove displaceable along the screw spindle; the I inemberand engaging with said comb projecting portion; and a handle, substantially as described.

In a safety razor, the combination of a guard plate; a back plate; a blade inter posed between said guard and back plates; a guard comb pivotally mounted on said guard plate and having a projecting arm; a guard-comb adjusting device comprising a screw spindle secured to said guard plate; and a knob screw-threaded on said spindle and having an annular groove engaging the end of said arm whereby to turn the guard comb on its pivot; and a handle, substantially as described.

3. In a safety razor, the combination of a guard plate having a cut-away side portion; a back plate overlying the guard plate; a blade interposed between said guard and back plates; aguard comb pivotally mounted within the cut-away portion of said guard plate and having a projecting arm; a guard-comb adjusting device comprising a screw spindle secured to said guard plate; and a knob screw-threaded on said spindle and having an annular groove engaging the end of said arm \vhereby to turn the guard comb on its pivotand a handle, substantially as described.

4. In a safety razor, the combination of a guard plate having cut-away side portions; a back plate overlying said guard plate; blades interposed between said guard and back plates; a guard comb pivotally mounted within each of said cut-away portions on the guard plate, and having each a projecting arm; a guard-comb adjusting device comprising ascrew spindle secured to said guard plate, a knob screw-threaded on said spindle and having an annular groove engaging with the adjacent ends of said arms for turning said guard combs on their pivots; and a handle, substantially as described.-

5. In a safety razor, the combination of a guard plate; a back plate; blades interposed between said guard and back plates;

guard combs pivotally mounted on said.

guard plate andhaving each a projecting; :1: 7570 7 portion; an adjusting device for said comb guards engaging with the projecting per-r tions thereof; a pair of pins passing.

through said guard and back plates; and a spring handle having bifurcated ends frictionally engaging with said pins and holding said guard and back plates in as sembled relation, substantially as described. In testimony whereof I have afiixed my signature in presence of two witnesses.
