UNIVERSAL SAFETY RAZOR.

Application filed May 11,

This invention relates to safety razors of the self stropping class, and more especially to those wherein the blade shield is removable to permit insertion of a strop, and whose handle is shiftable to a second position -to manipulate the blade when stropping the same.

The main purpose of my invention is to produce a razor having all the advantages of safety razors in general, and in addition that of having a positive and effective means for stropping the blade thereof without using any auxiliary appliances other than a strop.

Another object is to provide a razor of thls type with an efieetive blade guard which is adjustable to provide for wear on the blade occasioned by stropping and prolonged use.

Other objects and the various advantages accruing from the novel features of the invention will appear herein as the specification proceeds.

In the drawing forming part hereof;

In the use of safet razors it isthe common experience that lades must frequently be renewed, and as this is an item of expense, various additional devices have been proposed for rehoning and resharpening the used'blades. However the need has been felt for a self contained razor which can both be honed as well as stroppedwithout extraneous devices. This invention is designed with this thought and the previously mentioned purposes in mind, and in practice, a

actsas an interior limit for blade 10 which may be inserted between the opposite halves of grip 8. The blade is preferably hollow ground, both in order to render it easier to sharpen and also to have its inner portion heavier and easily retained. The grip has at one extremity a slightly bent or rounded edge at 18 to act as a stop for the blade, while the other has a similar edge at 19, which, however may expand a little as a spring by virtue of the cut away section at 20. The blade may thus be-slid out or into position at this end of the grip, and the spring edge 19 will tend to snap into position behind the blade and retain it. i

The frame has a dovetail block 21 secured beneath the same, and the handle normally screws up toward the same when the device is to be used as an ordinary safetyrazor. But a guard 23 may be interposed beneath the frame and may straddle the handle by virtue of its open slot at 24. The slot is actually-located in a plate? attached to the guard, and the latter has a corresponding larger dovetail slot 25 which is adapted to lit snugly outside block 21 of the frame.

Naturally if this guard is placed in position under the frame and the handle screwed into place, the latter will grip the edges of plate 7 and Wedge the same up against block 21 and thus hold the guard in position.

The guard has a series of teeth as noted at 6 as is customary in this class of devices, but the two extreme teeth are made in the form of hooksor blade retainers at 4 and 5, while the latter are rearwardly buttressed by a pair of inclines 14 and 12 which serve in addition to support the blade when normally held in' the retainers.

If the handle is slightly unscrewed, the guard may be drawn out of engagement, as

moved, when it is desired to hone and strop the blade. The handle may then be completely removed and inserted into one end of shaft 9 and screwed up tight. It is now temporarily a unit with the shaft and blade initially indicated in Fig. 3 and entirely rep Cal? - drawn over the stone until the desired result is attained, the only point needing attention being the frame 13 which may be kept out of the way at each stroke by giving the handle a toss each time. This operation is so obvious and accessible as to require no illustration, especially as this point is partly used in stropping, which operation is shown. in Fig. l.

Here, the strop is passed under the grip, and above the lower edge of the frame, so that the strep is captive during the stropping operation. ft is but necessary to turn the handle until the blade lies on the strop, when the blade may be drawn backward along the strop like any ordinary razor, after which the handle may again be turned the other way to lay the blade with its other side on the strop and the device drawn in the other direction.

This turning of-the handle and drawing the blade along the strep may be repeated until the blade is sharp, and is easily and directly under control at all times. More over, the pressure of the blade on the strop is also a point directly controlled at will.

When the blade is sufiiciently stropped, the guard may be mounted beneath the frame on block 21, the blade dropped into position on the inclines 12 and 14-, after which the guard may be pushed on until the blade stops the retainers 4 and 5. The handle may now be released and secured to the lower part of the frame and screwed up tight. This again assembles the whole into a unit.

The frame may be made of suitable metal and in any suitable size, naturally, and l may alter it to the extent of having a handle aperture in only one end of the grip shaft 9. In fact, one end may be enlarged as in dicated at 16 and may'have a very large handle seat as indicated at 17.

Various modifications of this nature may be made without departing from the spirit of my invention, and I therefore reserve the same as part thereof.
