Thisiinvention concerns razor blade hold-f:

ers for-employment during thestropping'of theblader 'Among the objects of this'i'nvention are to. provide certain combinations of elements v which enable the'quick and cheap manufacture of this type of devices; which fac'ili-e .tate the operations of placing removing the. razorblade; and pr'ovide as'imple'andi flat assembly for such structures. I

With these and other objects in view, as

will appear hereinafter, two forms of execit tion are shown on the accompanying draw p I wards, itpasses onto this 'spur'and inthis locks the two blade holder sections toings. J I

In the first modification, shown in Figs; 1 to 3'inclusive, the grip portion of the handle is a hollow. sleeve 10' formed by folding sheet f *metalto form a-flattened tube. 'The blade holder comprises the sheet metal member 11 and terminates short of the arched bridge 15. The tubular handle 10 fits over the strap 14 and its rebent extension 16, and carries a pin 17 which moves in a slot 18 in therebent withdrawal from around these members.

This member 20 has an arched bridge" 22 opposite the bridge 15, 'andextends *therebeyond as a spur 23 which I of the blade B when in stropping position.'.' 1 y The inboard brace26 likewise as an]...

to receive a rivet29 which'is secured in the metal: of thearched bridge15 and has an enlarged head 30 to prevent the removal of. the brace 26 therefrom. The hole is largerrthan the shank of the rivet'so that a rockingv move-v 'I nent. about the longitudinal axis ofthe blade is afforded.

Q In order to remove'abladef-romtheholder, thehollow sleeve 10 is drawn towards the moval, (Fig.2). A1 newblade. may now be placed in position, and by a reverse operation, the holderQO is brought down upon it and held in positiongby sliding the sleeve 10 t'othe left. g

beheld in clamped relation to each otherby the clips 43 at theright-hand or handle end.

Thesehandle elements have the bridge por tions 44 as before, and theblade holder sections 45 integral )with eachto support the razor blade B. The lower handle element 41 has'the studs 46'on its holder to support the blade as before, and is formed at theout board end of the holder with the upwardly bent flange 47 to carry the pivot pin 48 for the guard.

. The guard in thisinstance is formed of Wire crushed at themiddle of its length and perforated to receive the pivot pin 48. The

outboard end is straight .toform .a support 49 for the guard bars 50 which are spaced at a suitable distance from the pivot, and at the inboard end extendinward toward the handles. -Opposite the bridges 44, the

guard bars are bent towards the handles and 7 enter the same and arethen bent at 50 towards the free end of the handle. strap or clip 51 is fastened about the free ends of the wire to hold it in its proper position. A base '52 is fastened. rigidly to the lower handle member 41, and carries a spur 53 which is received. in the clip 51 between the two ends of the wire and constitutes the second pivot for the guard.

This. device is employed by disengaging the clips and swinging the upper handle about its pivot pin 42 into the position shown in Fig. 5, in which the blade is exposed and may be removed and a new one placed in position. By a reverse operation the members are brought together and clamped upon the new blade. 1 In each instance it will be seen that astifl" guard is provided, illustrated as being integral, and which presents itsguard bars at a regulated spaced and parallel relationship mem ers at those points assures a limitation of the rocking movement of the guard in its displacement from one face of the blade to the other, .and the stifi assemblage of the y guard itself maintains the parallelism of the bars with the edges of the blade.
