RAZOR;
srncrr'rcnrxon formingpart of Letters Patent at. eiaseaaatea January 17, 1899.
Application filed m 20, 1898. Serial No. 686,420. illo'model.) I I To all whom it may concern:
Be it known that I, FRANK PAT AK,a citizen of the United States, residing in the city and.
permanent back to which it is fitted, so that theblade can be at any time removed and replaced.
It consists,- essentially, of a channeled back having a permanent latching device at'the outer end and a transversely fulcrum ed lat'ching-lever at the inner end,in combination with 2b a blade having corresponding engaging devices formed upon it. v i 'It also consists in details of construction, which will be more fully explained by reference to. the accompanying drawings, in which-"- v Eigure lis a view of a razor, a portion of theback being broken away. Fig. 2 is a lonr gitudinal section through the back and connections Fig; 3 is a detail of the end lock ing devices. 1 The object of my invention is to provide an improved' means for looking a removable razor-blade to the permanent back.
' Where a razor-blade is formed with or permanently secured to the back-the wear upon the thin ,edge of the blade is somewhat rapid by constant use, and as the back always remains of essentially the same thickness the bevel or. angle-ofthe edge of the razor be comes more obtuse by wear and frequent sharpening until the work done by it is unsatisfactory and the razor must be cast aside.
My-"invention is designed to save the backs and handles and enable the operator to use any number of blades with'a single handle. In my device the back'A is pivoted to the handle B in the. usual manner forconnecting these parts in razors.
The back A has a longitudinal groove or channel-"made upon its front edge, of a width.
which will inst admit the thickness of the back of the blade 0 and a depth suflicient to receive enough of the blade to hold it'periectly rigid. between the sides of the channel -in the back. The outer end of the blade has a projection C with a tongue 0 extending approximately parallel with the back of the razor and at a little-distance therefrom, so as to leave a groove or channel betweenthe v tongue and the razor-back. The outer end of the handle has a slot made in it corresponding in length'with the length of the lug .0, and. at the inner end of the slot the'channel is extended along the back far enough to allow the tongue 0 to pass into the channel, when a corresponding projection within the back enters the slot between the tongue and the back edge of the blade. This looks the outer end of the blade firmly andperma- 7 blade has an extension D at the rear portion, and this is adaptedto slip into a slot made therefor in the back A, so that this extension enters the slot when the tongue 0 has engaged with the latching device at the outer end. Through the extension at the innerend of the blade is made a holed, extending at right angles with the blade.
The back A extends a sufficient distance to the point whereit is pivoted to the handle Band a depressed chamber is made in the side of this intervening portion of the back to receive a bar E and a head or button E, which is formed with the bar. This bar is pivoted within the channel or depression in which itlios by pin passing through it and through the back A, so that the bar may be tilted about this pin, moving transversely of the razor-blade. The outer end of the bar E has-a projecting luge, which enters the slot 0 din the rear end of the razor-blade, Beneath ,the button E is a spring F, of any suitable I Orwell-known form, the tendency of which is to pressthebutton outward and correspondingly press the lug at the other end of the 5 bar E inwardly.
Then the blade of the razor is to be attached to the back, it is slipped into the channel in the back andpushed along. until the H and the inner extension passes beneath the i lug 8 upon the bar E until the lug drops into nently to the back A. The inner end of the 70 lug c is engaged and locked at the outer end,
the hole (I- in this extension "of the blade. Both ends of the blade are thus firmly locked to the back A, and the blade can only be removed by depressing the button E until the lug e is lifted out of its engagement with the hole (I of the inner end of the blade. When this is done, the blade can be slipped outwardly and the outer lug 0 simultaneously disengaged from-the holding device at that POint.
lhe value of this construction lies especially in the transverse movement of the locking-arm E and the fact that it and the button by which'it is operated lie upon the side of the part A- instead of upon either the front or back, and being sunk into the depression in the-part A they are essentially flush with The construction which I have shown, howits surface and not liable to be pressed open, so as to accidentally disengage the blade.
In using the razor the useifl ordinarily presses the finger upon the corrugated depression at the inner end of the part which holds the blade and just behind the blade, and if the button were placed at thispoint it would always be in danger of being disengaged, so as to allow the blade to slip out.
\ ever prevents this, and as it is behindthe blade it is not subjected to any accidental pressure when the razor is being honed or strapped.
Having thus described niyinvention, what I claim as new, and desire to secure by Letters Patent, is
. An improved razor consisting of a longitudi 3 5 ing in the blade, and having at its opposite end an operating finger-piece, and a spring in said depression and, between the wall of the latter and the inner side of the'bar.
In witness whereof I have hereunto set my hand. 1 v
