I RAZOR BLADE SHARPENER Edward Scarlett, Oklahoman City, Okla Application July 5; 1533; SerialNo. 679 ,120

l Claims.' (01.. 51 -218).

t Thisinvention relatesto razor bladesharpen' ers and has foritsobject the prov-isi'onofa very simple and efficientdevice whereby razor blades may be held firmly to the sharpening surface and moved over the same easily to acquire the desired edge.

The invention provides means whereby two blades may be disposed at opposite sides within a cylindrical body and reciprocated over the inner surface of said body rapidly and easily, the release of the blades being just as easily accomplished.

The invention is illustrated in the accompanying drawing and consists in certain novel features which will be hereinafter first fully described and then more particularly defined in the appended claims.

In the drawing:---

Figure 1 is a view showing the blade holder in side elevation and the cylindrical body in longitudinal section.

Figure 2 is a view showing the holder in end elevation and the cylindrical body in transverse section. I

Figure 3 is an enlarged section on the line 33 of Figure l.

Figure 4 is a detail section on the line 4-4 of Figure 1.

Figures 5 and 6 are side elevations of the blade clamp showing different forms of blades held therein.

It is contemplated to employ a cylindrical body 1 of flint-glass and to reciprocate the blades over the inner concave surface of this glass body while they are held within a holder or handle member, designated as an entirety by the numeral 2. This handle member is formed from a single continuous length of stout wire or light rod doubled upon itself, as shown at 3, to produce arms 4 which diverge from said central point. At points intermediate their ends, the arms 4 are bent toward each other to produce the intermediate crossing sections 5 whereby their terminals 6 are disposed in spaced relation and may be spread apart by exerting pressure upon the diverging arms 4, as will be understood. A yoke '7 is mounted slidably upon the arms 4 and consists of a flat plate of metal having a finger-hold or lip 8 bent up from one edge and provided at its ends with sleeves or guides 9 and 10 which are slidably engaged about the arms 4, as clearly shown. These guides or sleeves may be entirely closed or may be partly open and in Figure 3 I have shown the guide 9 as closed entirely around the engaged arm 4,

While the guide' 10 is partly open to facilitate its engagement orrelease from the arm; It' is also to benoted that the sleeve-or guide 9 is longer than the sleeve or guide 10, the yoke being thus adapted to have a slight play upon the side arms 4 of the holder and accommodate the angular relation thereof so that as the yoke is moved toward the bight 3 of the handle it will not bite into the arms while at the same time it will hold them with sufficient frictional resistance to maintain the terminals 6 in the desired set position.

Upon each terminal 6 is mounted a clamp comprising a loop or sleeve 11 which fits slidably upon the terminal portion of the holder rod and from one end of which extends a metallic strap 12 which passes to the extremity of the terminal member and is then bent across the same, as shown at 13, said transverse portion 13 having a lip 14 formed thereon at the outer side of the holder arm to cooperate with a thumb screw 15 in clamping the blade in place.

A strap 16 is secured upon the outer side of the sleeve 11 and extends at one end to the cross member 13, while its opposite end is doubled upon itself, as shown at 1'7, to form a bight receiving one end of an outer clamping plate 18 which has its opposite end engaged between the lip 14 and the end of the strap or plate 16, as clearly shown in Figure 1. The razor blade, indicated at 19, is fitted between the straps 16 and 18 and the thumb screw 15 is then turned home so that the blade will be veryfirmly clamped between said straps. The blade will project from the clamp so that its edge will rest against the inner concave surface of the cylindrical body 1 and may be moved readily over said surface by rocking or oscillating the holder. The device is exceedingly light and may be readily manipulated to produce the desired edge upon the plate without fatiguing the user and it is necessary to merely twist or rock the holder about its own longitudinal axis in order to bring the blade into usable condition.

When a blade with a single cutting edge is to be sharpened, the back edge of the blade is fitted in the clamp and secured, as shown in Figures 2, 4 and 5, while if a double-edge blade is to be sharpeneds the blade is inserted through the clamp so that its central longitudinal portion will be secured thereby, as shown in Figure 6. When the blade has been provided with a cutting edge, a release of the thumb screw will permit the blade to drop from the clamp. The holder being formed of continuous light rod or stout wire in the form shown will possess considerable resiliency and this property will cause the terminal portions 6 to tend to spread apart so that they will be very easily held against the abrading surface without exerting a strain upon the users Wrist.

Having described the invention, I claim:

1. A device for the purpose set forth comprising a single integral handle member, comprising diverging arms having their terminal portions crossed, blade-carrying clamps mounted upon the terminal portions of said arms, and a yoke engaged with the arms to maintain the terminals in a set relation. g

2. A device for the purpose set forth comprising a handle member having oppositely disposed terminals, sleeves mounted upon said terminals, straps extending from the sleeves at opposite sides of the terminals, a clamping strap disposed at the outer side of the outer strap, the clamping strap and the said outer strap being adapted to receive a blade between them, and means 00- operating with the straps and the handle terminals to clamp the blade in place.

3. A device for the purpose set forth comprising a handle member having oppositely disposed terminals, sleeves mounted on said terminals, straps extending from the sleeves and adapted to receive blades, and securing devices mounted on said strap engaging the terminal members whereby to clamp the blades in place.

4. A device for the purpose set forth comprising a handle member having oppositely disposed terminals, sleeves mounted on said terminals, straps extending from the sleeves at opposite sides of the terminals, the strap at the inner side of a terminal having a transverse portion extending across the end of a terminal, a clamping strap disposed against the strap at the outer side of the terminal and engaged with the transverse portion of the first-mentioned strap, and a securing element mounted in the first-mentioned. strap and bearing against the terminal whereby to clamp a blade in place.
