BAZQR-BLADE-SHARPENIG DEVICE.

To all whom 'it may concern:

Bc it known that I, WALTER W. RICHARDS', a. citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, 'have invented certain new andl useful .Improvements in Razor-Blade-Sharpening Devices, of which the following is a' specification. f

My invention relates'to-improvements in raaor blade sharpening devices, and more particularly to an improved holder forse curing safety razor blades in suchposition that they may be readily stropped.

A further object is to prov-ide an improved clampinfr bar which is adapted when.

moved longitudina-lly relativeto a blade supporting -member -to firmly clamp -the bla-de between `the bar and said member, so

that both edges ofV the blade Willup'roject beyond the bar, and the 'member in position to be sharpene lVith these and other objects in view,the4 invention consists in certain novel features of construction and `combinations andarrangements of partsasvvill be more fully hereinafter described and pointed out in n the claims.

In 'the accompanying drawings: Figure lis a plan view illustrating a safety razor' blade clamped in .one lform of. my improved holder. .Y Fig. 2vis a View inl-ongitudinal section of Fig.` 1. Fig. 3 is a perspective vien7 of' the clamping bar illustrated in Fig. y2. Fig. 1 is a fragmentary perspective view of the handle member. shown in Figs. 1 and 2.

F ig. 7is ai planfview illustrating my improvements in connection with a safety" razor blade holder. Fig. 8 is a view in longitudinal section on the .line 8-8-01" Fig.,7. Fig.- 9 is a perspective view of the blade clamping bar illustrated in Figs- 7 and 8. Fig. 10 is a View in longitudinal-sec-- tion illustrating the use of the bar shown in Fig, 5 in connection with thehandle member shown in Figs. 1, 2. and 4, and Figs. 11 and 12 are plan views illustrating types of' safety razor blades which are adapted to be securely'held by my improved mechanism so that they may be sharpened.

l represents a handle which is p-rovided at one end" With a blade supporting member 2 which is, as a matter of fact, a continua-- tion of the bar forming the handle, and this Specification of Letters-Patent. y Application led July 2:2, 1913. Serial No. 780,438.

blade supporting member is of a width appreciably less than the Widthof the blade 3 to lbe sharpened, and has a `flat surface to bear against the blade and clamp the same against a clamping bar 4. The clamping bar -1'is provided with a pair of lugs 5 offset from the planes off the clamping` bar.

`ing member 3 is provided with a pair of slots adjacent the ledges and through which the lugs are -passed after being projected through the slot in the blade.

The blade supporting member 2 at its free end is'formed .with a finger S which projects between inwardly projecting fingers SJ .o'n the outer end of bar L to prevent any lateral displacement of the bar. The inner .end of bar ais beveled as shown at 10am] is adapted to move into a recess 11 in the supporting member 2 and adjacent this beveled end 10, a,lip 12 is' provided on har 4, so that it may be readily engaged by the finger of the operator to move the bar 4 longitudinally and operate the latterI to either clamp or release the blade.

The bla-de Slabovereferredto is a: common type in general use, and-,with which my improved device above described is especially adapted. In Fig. 12, vI illustrate another formof blade 1&1 which isV in extensive use, and this blade has three openings 14. To secure this form of blade 13 to the supporting member 2, I employ a clampbar 15 such as shown in Fig. 5. This clamping bar 151s provided at one end with the ngers 9, and at its other end with the beveled end 10 and the lip 12 as is the bar 4 above described. v

In place of the lugs 5,1 provide on the bar 15, three lugs 16, circular in cross section to fit within the circular' openings 14.

The intermediate lug 16. is appreciably shorter than the other lugs. This arrangement is provided because while the end lug 16 may be projected through the slots G in the support-ing member 2, the intermediate lug must be accommodated in a recess 17 formed in the support 2.

y In Fig. 7 I illustrate a modified form of blade clamping bar 18 which is utilized in connection with a blade supporting member bar 18 is moved longitudinally, the lugs 5v will exert a cam action and clamp the blade between the bar and the support. An eX- .tension 29 is provided on one end of bar 18 and is provided with alip 2O to facilitate the manipulation of the bar. juncture of the extension 19 and bar 18, a. shoulder 21 is formed which engages a corresponding shoulder 22 on support 19 to limit the longitudinal movement of bar 1S in one direction.

It will be noted that with my improve: ments it is simply necessary to move. the

blade clamping bar longitudinally either to clamp or release the blade. This manipula` tion can be accomplished by holding the supporting member with the hand, and with the thumb of the same hand pressing against the lip 20, move the blade clamping bar without danger of cutting the hand.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by LettersPatent is:

1. The combination with a blade supporting member, a bar movable longitudinally relative to the supporting member, means coupling the y bar and the supporting mem- At the ber together when said bai' is moved longitudinally in one direction, whereby a blade may be clamped between the supporting member and the bar, said supporting memb'er having a recess at itsdnner end, said bar having a beveled inner end ada ted to be projected into the recess', and said bar adjacent said beveled end having a lip ada ted to be engaged and moved bythe thum to project the bar in a direction to move the inner end out lof the recess and release the blade, substantially as descbed.

2. In combination with a blade su porting member, a bar movable longitu inally relative to the supporting member, said member and said bar both of a Width appreciably less than the width of the blade to be held so that the latter will project at both edges beyond the bar and the supporting member, means coupling the bar and the supporting member, whereby the longitudinal movement of the bar operates to clamp a blade between the same and the sup porting member a finger on oneend of said supporting member, inwardly project-ing iingers on the end of the bar adaptedto receive the rst-mentioned finger between them when the bar is moved into clamping position, said supporting member having a recess, said bar havinl a beveled inner end adapted to be moved into the recess, and a lip projecting at right angles from the bar at a point adjacent said beveled end, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
