SAFETY RAZOR.
Application led October 17, 1928.
This invention relates to safety razors of the type wherein the razor blades are provided by a continuous flexible steel band.
rlihe invention seeks to provide an inexa pensive structure, eficient inservice and effective and convenient in operation.
The invention consists of the features hereinafter pointed out and set forth in the claims.
In the accompanying drawings forming part of this specification, and in which like reference numerals designate corresponding parts,
Fig. 1 is a section of the razor on the line 15 1 1 of Fig. 2.
FFig. 2 is a section on the line 2-2 of lig. l.
Fig. 3 is a plan view of the head of the razor partly in section and partly broken 2G away.
Fig. 4 is a detail showing the steel band which provides the cutting edge.
Figure 5 is a cross sectional view of the parts by which the cutting edge of the steel band is sharpened and preserved.
Referring now to the drawings, the head of the razor 1 and the handle 2 are constructed in the form of a hollow casing, preferably of light sheet steel. The to 30 plate 3 of the head is provided with teetii 1 which teeth provide the usual guard for the cutting edge. The plate 3 which extends across the head defines the cutting position and provides a support for that section of the cutting band which, for the time being, is in cutting position. The cutting band 5 is, provided with perforations 6. It extends across and immediately above the support 3, thence down through one side of the handle and up through the other side thereof. 'At the bottom of the handle, it passes around a drum 7 provided` with teeth 8 which engage the perforations 6 of the band 5. This drum is fixed on a shaft 9 mounted in the opposite sides of the handle, one end of which projects outside the casing and has pivotally fixed thereon a ring handle 10. Also xed on the shaft 9 is a toothed gear 11 provided with a spring pawl 12 whereby 5U rotation of the drum is permitted in only one direction. Formed in the handle at its lower end is a recess 13 in which the ring may be folded when not in use. The head of the razor is provided with an inset M 11 to facilitate the action of the cutting Serial No. 312,940.
edge when in use. Projecting through a central aperture 22 in the supporting plate 3 1s a plate 15 mounted on a pivot 16.A The forward edge of this plate 15 bears against the rear edge of the band 5 on that section of the band in cutting position when the same is in active use. 1t may be adjusted by a thumb screw 17 which projects on the outside of the head. The abutment 15 acts to push forward that section of the band which is 1n cutting position so that its cutting edge may be always kept forward in its most advantageous cutting position and may thus compensate for any possible decrease in the width of the band due to sharpenin It also acts to resist back thrust on said section of the band when the same is in active use. Immediately above the supporting late 3 is a clamp plate 18 secured in place y a hinge v19 providedv with a spring 20 which acts to press the clamp down against the steel band so as to hold it firmly against the supporting plate 3. 21 is a spring ten sion device over which the band passes, the same acting to keep the band suiclently taut.
Within the handle and secured thereto is a pair of pads 23 and 24 which closely embrace the band 5 on either side. These pads are preferably well oiled before being secured in place and serve the purpose of cleaning and oiling the band as it passes between them so as tov keep the band free from rust. Also within the handle and opposite the pads 23 and 24 is a pair of sharpening devices 25 and 26 which closely em-4 brace the band 5 on either side thereof. They may be made of stone, leather or other material, and serve to sharpen the cutting edge of the band as it passes therethrough.
Figure 5v illustrates the manner in which the devices' 25 and 26 engage the edge of the band 5 and keep it sharp.
The part 26 preferably bears against the band with a yielding pressure. As shown in the drawings, this is provided for by se 10o curing the part 26 to a metal plate 27 which has a to and fro movement on supporting pins 28 and 29 passing through slots in the ends of the plate 27. Coiled springs 30 and 31 are interposed between the plate 27 and 105 the back plate 32 fixed within the handle. The band is guided through the head by small rolls or pins 21, 34, 35, 36 and 37 fixed therein. The band 5 also passes between a pair of pads '38 and 39 mounted at 11o and wiped.
head. These pads are .preferably made of felt or other suitable material and serve t-he purpose of wiping the band as 1t asses therethrough and removing oil or molsture from'the band.
By providing the razor with the casing 1 and handle ,2' with the` drum 7 in the outer or far'end of the handle,I am enabled to use a band 5 o f greater length and at the same time 'have suci'ent s ace for the sharpening devices 25 and 26, t e oiling pads 23 and 24 and the wiping ads 38, 39, 40 and 41. At the same time t e razor is not made bulky, but it can be constructed in relatively small sizes and be neat and compact in design, with the band 5. large enough for long service and the other 'parts capable of active cooperation with :great efficiency to'4 keep the ed e of the band sharpened and the whole outsi e surface of the band lubricated to expose a. portion of said edge adjacent the guard, with a toothed rotatable drum over which the band passes disposed at the outer end of the handle, the teeth of the drum engaging the perforations in the band to adjust different sections of the band consecutively into cutting position.

In a safety razor having a head with a guard and a handle for the head, the combination of an endless steel band having a continuous cutting edge and perforated throughout its length with a toothed rotatable drum over which the band passes disposed at the outer end of the handle, the teeth of the drum engaging the perforations p in the band to adjustl different sections of the band consecutively into cutting osition, and a sharpening device in the han le comrisingr two elements between which the hand passes as it is driven by said drum.

7. In a safety razor, the combination of a hollow case providing a head and a handle a toothed support in the head, a perforated endless steel band having a continuous cutting edge and adapted to have its various sections moved consecutively over said toothed support, a toothed drum mounted at the outer end of the handle over which said band passes, said drum being rotatable .to bring succeeding sections of the band over said toothed sup ort and so as to occupy the cutting position thereon, and a clamp to hold the band down on said support.
