sArETY-nezonl .j the following is a specilication.

This invention .relates to improvements on what is known in the trade as a Durham duplex safety razor.

One of the objects of the pesent inven' tion, is to provide a two piece guard plate,

one section of which forms the guard, while the other section serves as a clamping plate to secure the blade on the razor.

Another object of the invention, is to provide 'a hinge connection between the two plates together withv a locking device fory securing same together, which, when re-` leased, will permit the guard plate to be folded back on the shank of the razor, in this `manner exposing the blade,l and permitting the four 'sides of the blade to be honed or stropped without removing the blade.

vFurther objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in whichf- Figure l is a perspective view of the razor, showing the blade and guard plate removed. Fig. 2 is a view of the blade. Fig. 3 is a perspective view of the sectional guard plate,

showing the clamping plate partly opened. Fig. 4 is a cross section, on' line 4 4, Fig. 3. Fig. 5 is an enlarged, vertical, longitudinal section through the razor, showing the parts in locked position. Fig. 6 is a plan view, showing theblade applied and guard plate to be turned back to permit the blade to be strOpped.

The Durham duplex safety razor, which is extensively used at the present time, is provided with a stropping attachment. In order to use the stropping attachment, it is necessary to remove the guard plate and then apply the stropping attachment; this stropping attachment when applied, only permits the stropping of one edge of a blade, and to permit stropping of the other edge or side of the blade, it is necessary to remove the stropping attachment, reverse the blade an'd again apply the stropping attachment. This operation takes time, and is more or less inconvenient, as it necessitates removal and Specification of Letters Patent. lApplication'flled September 15, 1915. Serial No,

reversal of the blade several times, before both edges are stropped.A

The object of the present invention, is to I provide a sectional guard plate, one section of which c an be folded back on the shank of the razor, in such a manner that both cutting edges of the vblade are uncovered, or so exposed that both stropped without removing or reversing the blade. This is accomplished in the `followin manner:

eferring to Fig. 1, A indicates a handle; 2 theshank pivotally mounted therein, and 3 the holder upon which the blade 4 is supported and clamped by the guard plate, generally indicated in Fig. 3. This guard plate is in the present instance, made in two sections, 5 and 6; said sections being secured together by a hinge connectionV 7. The plate 5 is provided with a-pair of downwardly turned, iexible spring construction to those now in use), which are adapted to pass through the slot 9, in the blade and the openings 10, in the holder, to

tongues 8 (similar in -cutting edges may be I secure the blade in the usual manner, while necessary to lay the blade on the clamping plate 5, in a position where the spring tongues 8 will project through slot 9 in the blade. The blade together with the clamping plate and guard plate 6, is then placed upon the holder 3, y in a position where tongues 8 will project through the openings 10. The connectedplates 5 and 6 together with the shaving blade is then moved in the direction of the shank 2 or handle A, causing the spring tongues to enter a pair of shallow pockets 10a formed adjacent to the openings 10.

If it is desired to strop the blade when applied to the holder, as described it is only necessary to move the plate 13 with the lock in the direction of arrow a; this causes the latch 14 to move out of engagement with the clamping plate into the dotted line position, shown in Fig. 5. The guard plate is Y thenfree to moveabout the hinge 7, inthe -direction of arrow Z1, and may be folded down flat with relation to the shank 2 and handle A. This position is shown in Fig. 6. By referring to this gure, Vit willbe seen that both the cutting edges of the blade 4 are exposed. The razor may then be stropped like an ordinary razor, first to sharpen one 'cutting edge, .and then the opposite cutting secured by sliding the plate 13 back into the full line position, shown in Fig. 5, where the latch engages with the clamping plate.v

Therazor is then ready for use,'and both cutting edges are guarded by the ngers 11,

which project over the edge of the blade.

For the purpose of making the sectional guard plate as compact and flat as posslble and also for the purpose of bringing the guard fingers 11 into the correctposition with relation to the cutting edges of the blade, it

is preferable to form a channel 16, on the lower side of plate 6, which is sufficiently deep to receive the clamping plate This produces a compact, fiat construction and adds very little to the weight or cost of construction.

The razor as a whole, is substantially the same as the Durham duplex safety razor on the market, the only change in construction being that of the guard plate, which in this instance, is made in two sections. Theopenings produced in the clamping plate by forming the tongues 8, together with the slot 9, formed in the blade permits the application of the lockingdevice withoutJ making any changes or alterations in construction of the parts already manufactured.

As the latch 14 on the locking device is so positioned, that is passes through slot 12 and the opening 8a in the clamping plate directly into the slot 9 of the blade, the sectional guard plate may therefore, be bought as an attachment to the razors now manufactured or in use, and applied directly to same without making any changes or alterations. The sectional guard plate constructed' as here shown protects the razor blade in the usual manner, and may be folded back away from the blade without any trouble or loss to time, thus permitting both cutting edges of the blade to be honed or stropped without re'- `moval or the application of any other device.

The majority of safety razors including the Durham duplex safety razor, now in use have extra stropping attachments, which cause considerable delay when shaving, as it is necessary to remove the old guard plate and turn the blade about while stropping the two cutting edges. The hinge on the guard plate proper4 furthermore permits cleaning of the blade, etc., the lather or any otherl accumulation may be removed, by simply opening the guard plate.

It is particularly to be noted that the blade 4 is, when the guard is swung back to.

rest against the shank 2, located between the holder Sand the section 5 of the guard plate and is clamped rigidly by the section 5 alone, and independent of section 6. This clamping of the blade by section 5 alone is of vital importance since in order to strop, the guard section 6 must be moved to inoperative position in which it 'is incapable of holding the blade rigid. Further the opposite long1tudi nal sides ofrthe'holder 3 and thesection 5 serve to provide guides which hold the blade at the proper angle to i the strop during stropping. The hinge 7 of the guard section 6, is also located at theinner end of the blade so that vthe same may be swung to liebetween the inner end of the blade and the handle A and be held immovable by the lthumb of the operator and in a position to not interfere in any manner with stropping `of the blade,

y The tongues 8 are struck-out leaving apertures, 4and the 'slidable latch 14 operates in the aperture formed by the striking-out of one of the tongues as depicted in Fig. 5 so as to engage the inner face of the section 5.

The materials and inish'of Vthe several parts of the device may be such as the judgment and experience of the manufacturer may dictate.

I wish it understood that variouschanges in form, proportions and minordetails of construction may be resorted to Within the scope of the appended claims, and that I do not wish to limit myself to the specific design and construction here shown.'

Having thus described my invention, what I claim and desire 'to secure by Letters Patent is- 1. In combination with a razor handle having an apertured shank, a guard composed of an inner blade clamping section having struck-out tongues engageable in the shank apertures, and an outer section h'avy ing alatch engageablein one of the openings formed by the struck-out tongues of the inner section.

2. In combination with a razor handle having an apertured shank, a guard composed of an inner blade clamping section having struck-out tongues engageable in the lshank apertures, and an outer section hinged at its inner end tothe inner end of the inner section and having a latch engageable in one of the openings formed by the struck-out tongues of the inner section.

3. A safety razor comprising a blade, a blade holder, a detachable clamp for securing the blade to the holder, said clamp having an opening therein, a guard hinged to 130 and clamp together.

4. A safety razor comprising a Kblade I holder having spaced openings, a blade having an elongated opening, a blade clamp having tongues passing through the blade opening and engaging in the holderl openings, said clamp further having an opening over the blade opening, a guard, and a locking device carried by the guard and 'provided with a hook part adapted for engaging in the clamping opening, the blade serving as a spacer between 'the clamp and holder to permit of the hook terminal engaging the inner' face of the clamp.

5. 4In combination with a handle having a rigid blade holder disposed in substantially the same plane therewith, a clamp removable from the holder for clamping a double-edged blade to the holder, a guard movably connected to the clamp so as to be removable from the holder with said clamp,

and a latch for securing the guard positively to said clamp, said guard being movable to an inoperative position while the clamp'is in clamping position to expose both edges of a blade for stropping. p

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.v
