To all lwhom 'it may concern.'

GEORGE D. SNIDER, citizens of the United States, residing at Blacksburg, in the county of Montgomery and State of Virginia, have invented certain new and. useful Improvements in Detachable-Bladed Razors, of which the following is a specification, ref'- ierence being had to the accompanying drawings.

blade shank is pivotally connected to a handle, so that the shank may be turned either into operative position or into a position within and housed by the handle.

The general object of the invention is the provision of very simplemeans whereby the blade may be detachabl held .to the shank so that the blade may he readily removed and a new blade inserted..

A further object of the invention `.is to provide improved locking means for holding the blade in place so that it cannot become loose or fletached and still another object is to improve the details of construction of the razor so that it may be cheaply made and so that the parts will be firmly held in their coperative position.

Other objects will appear in the course of the following description.

Our invention is illustrated in the accom-` panying drawings, wherein Figure 1 is a side elevation partly in section ofa razor constructed in accordance with our invention; A

Fig. 2 is a top plan view of the-shank:v of the razor, the latch being in section;

Fig. 3 is a section on the line 3 3 of Fig. l; g

Fig. 4 is a perspective viewv of the latch;

Fig. '5 is a side elevation of the blade detached. y

Referring to these drawings, 10 designates the usual handle of razors of this type formed of two spaced strips. Pivotally mounted upon a pin or rivet 11 is the shank 12 of the razor, Vthis shank havin a vsolid tang 13 extending rearward there rom and formed to t the nger, as is usual. This tang is preferably made of a strip of metal bent upon itself, so as to be approximately U-shaped in cross section, the space in the ,tang rearwardof the pin 11'being lled or otherwise rendered scild, as heretofore stated. Extending through the lateral walls This invention relates. to razors and par ticularly to that type ofrazor in which the of this tang are the rivets 14, two of these rivets being shown. One side wall of the tang is formed with a slightly projecting inwardly extending boss 15 which may be formed by pressing the side wall inward.

The blade 16 has, to all lintents and purposes, the form of an ordinary razor blade,

but its back is provided with two bayonet slots 17, which are adapted to coact with the pins or rivets 14. Theinner end of the blade is rounded at 18, but at its inner corner the blade is formed with a slight proj ection or lug 19. Outward of this lug the end of the blade is flat. Y

For the purpose of holding the blade in place, we provide a locking member or latch 20. This is formed of a strip of metal approXimately T-shaped in cross section which at one end is reduced and formed with a perforation through which passes the rivet or pin 1l so that the latch 20 is pivoted to the shank 12. The lower edge of the latch has the laterally extending flange 21, but the body of the latch may be inserted between and fill up the space between the side walls 12. The Afree end of the latch is straight, as at 22, but the inner corner of this free end is rounded -as at 23. The metal of which this latch is made is provided with a depression 24, which, when the latch is swung into place between the side `walls of the shank 12 is engaged by the inv ward projection 15 and this locks the latch in its operative position. Preferably the outer face of the Hange portion 14 is toothed or serrated.

In the practical use of this device, the

blade is disposed with its slots in engagement with the ins or rivets 14 and then shifted longitudlnallyto the position shown in Fig. 1 and thenthe latch 20 is swung being lshaped in cross section, the resistl ance of the detent boss 15 being only sufiicient to hold 'the latch from accidental detachment. Thus it may be seen that a new blade may be easily substituted for an old blade, so as to permit the old blade be ground by machinery. lt would seein that the construction which We have provided is very simple, may be cheaply made and that the blade is held very firmly and solidly in place and, furthermore, that the blade is held from any outward movement by the engagement of the bayonet slots with the rivets 14 and not by a mere engagement of the latch with the end of the blade.

Having thus described our invention, what We claim is A razor including a handle and a hollow shank, a pivot pin running through the handle and the shan.; and pivotally connecting the same, transversely extending rivets disposed through the shank, a blade having bayonet slots on its back engageable with said rivets, the inner endof the blade at its back marginal portion being provided with maglie? a lng extendingl outwardly of the blade, and a latch pivoted on said pivot pin and swinging thereon into the hollow shank to engage the rear end of the blade and overlie the lug` ot' the blade whereby said blade is prevented from being shifted to disengage it from the rivets, 'said latch being "1F-shaped in cross section, opposed faces of the latch and shank being provided with eo-acting means for holding the latch in engagement with the inner end portion of the blade. n

ln testimony whereof We hereunto aliix our signatures in the presence of two Witnesses.
