To all whom i se/neem: l.

Be it known that i, ijrr'nar H. Unsrnonn, a citizen of the United States, residing at l Fremont, iu the countyiof Sandusky and l State of Ohio, have invented'certainnew and useful improvements in Safety-Razors, of which the following is specification. The purpose and object or' my improvement is to provide a razor or' the class named, which has fewer parts; is less conij alicated;y and easier to set together and take apart, than other razors of that kino; and

is so held as to stilfen it throughout its length.

Referring now to the drawings: Figure 1 represents a front view; and lJig.` Q a rear view, the handie being removed. Fig. 3- represents in perspective the retaining plate, a front view of which is seen in Fig. 1. Fig. 4 represents a cross section, on the line A. A of iig. 1. Fig. 5 represents a cross section, on'the line B if, of Ifig. 1; both slightly enlarged.

Coming to a more specific description of iny invention: Generally speaking the blade 1 is 'clamped vand held, between a guard plate 2, and a retaining plate 3. he guard plate is provided with a rearwardly projecting shank et, and a pair of retaining fingers 5 which project forward fromA the upper edge of said plate. Said fingers are made to reach over and clasp the back edge of the razor blade. While said lingers aid inholding the back edge of said blade, their chief function is that of alining its cutting edge l:1 with reference to the guard edge of said plate. The lower or guard edge vof saidV plate is cut away in the usual manner with such guards, causing the same to have a comb edge. The projecting ends of the teeth 6 of said comb, are curved rearward and away from said blade, in the usual manner, so as to render the knife edge of said bladefree for shaving purposes.

The two end teeth 7, as represented in Figs. 1- and 5 while given asimilar rearward curve, are given a. longer tangent, and so made to bear close against said knife edge, for the purpose of preventing the operator from cutting himself with the corners of said blade. Said shank a has a perforation 8, which is intendedto receive the may be connected otherwise if desired, but from preference, l use the screw thread for the purpose of making said handle detachable. ii'or purpose, hereafter explained, said plate 2 is provided with latches 11, which are pivoted to the rear side thereof by a stud 12, as shown `best in Fig. 2. Said blade being in position, with the back edge thereof clasped by the lingers 5 it is otherwise held rigidly in place by means of the retaining plate 3. ln order that said blade may be held against any lateral movement, I inake said blade, and the plate 2, of equal length;

and to engage said ends I provide said plate with flanges 13. In order that said plate may be made to bear flat against said blade and thus not onlyhold the same, but stien it, upon the one hand I provide said iianges with rearwardly extending latch keepers 14, made to engage and cooperate with said latches 11; and upon the other, I provide the upper edge of said plate with a rear wardly curved inger l5, made t enter an aperture 16 in said shank 4, and, with the back thereof, to bear against the inner 'or under surface of said shank. When in position, the inner side of said linger is made to rest upon thelower edge of said' a erture 16; and thus said late is held from falling,

and thereby said nger is'held against dis-A engagement with the inner surface of said shank. Suitable recesses 17 are eut 1n the upper edge of said plate 3 to receive the fngers 5. In Fig. 2, one of the latch keepers 14 is cut away froni'its vflange 13, leaving 'a sectional View Aof the projecting portion. 1n Fig. l a part'of the plate 3 is broken away to show the blade 1. Having now fully described my invention,

what l claim is:

1. An improvement in safety razors, coinprising: a razor blade, clamped and held between a combed guard-plate upon the one side thereof, and a retaining plate upon the other; in combination with said plates, and screwless means for clamping and holding said blade therebetween, a part of which means, performs 'the 'further function of alining the knife edge of said blade with reference to the guard edge of said guard plate, the back edge of said guard plate being provided with a rearwardly curved, and handle-connecting shank, made integral therewith, substantially as set forth.

2. An improvement in safety razors coinprising: a razor blade, clamped and held between a shanked guard-plate upon the one side thereof, and a retainingv plate upon the otherin combination with vsaid plates, and means for clamping and holding said blade therebetween, which comprises: la flanged end, and latchkeeper, for each of the endsof 5 said retaining plate, together With a copf erating latch, one for each such keeper, and which is pivoted to the rear side of said guard plate; and a finger which rises from the upper edge of said retaining plate, '10 lwhich said finger curves rearward and is made toenter an aperture in said shank, and. i

when in osition, to have the back thereof ngflged y said shank; substantially as seti ort I In testimonf'y whereof I aix my signature 1,;
