At a point'near the'bevelled Aend of the Figure 8 is a side view of the same when cover plate 33 is a notch V35'in the rear edge locked in a position to that shown in Fig. 6. and on the bottom vplate 28 is a correspond- 10o ing detent 36 adapted to spring into the notch and retain the cover plate in a closed position.

In order to facilitate release of the cover plate, and consequently the blade 31, an eX- tending lug 37 is provided and is conveniently arranged adjacent the end of the blade and to which pressure may be applied upwardly in overcoming the detent 36.

Pivoted on a pin 38, between the sides 16 of the handle, is a cam 39 adapted to engage in any of the recesses 24, 25 and 26, positively locking the holder 20 in any of its adjusted positions.

Integral with the cam is a lever 40, its inner surface being serrated in the manner of a file as at 41, and having its end 42 shaped as a nail cleaner, one of the purposes of the lever being that of a manicure implement.

Near the free end of the lever are a pair of opposed outstanding lugs 43, these lugs smoothly engagin in recesses 44 formed in the back of the ho der and serving to confine the lever when depressed, it being understood that the lever at such time is disposed level with the rear edge of the handle between its sides.

Formed through the sides 16 of the handle are openings 45 rounded on their outer edges and smoothly Iinished, the openings being adapted to receive the end of a cigar, which` may be clipped by manipulating the blade in an obvious manner.

In the modification shown in Figs. 7, 8 and 9, the handle 50 is made in a similar manner from sheet metal folded into a channel shape and engaging a blade holder by a pivot 52, said holder consisting of a relatively heavy bottom plate 53 carrying thin headed studs 54 engageable in slotted openings 55 in a spring cover plate 56, the longitudinal edges of which are bent to rest upon the plate 53, at one side and upon the cutter blade 57 along the other side, holding it in firm contact with the bottom plate 53, it being understood that the blade 57 is rovided with openings to permit the stu s to pass through freely.

A spring lever 58 is pivoted by a pin 59 to the handle 50, the lever having fixed in its free outer end a pin 60 to pass freely through either of the perforations 61 or 62, in one side of the handle and engage in corresponding openings 63 and 64 in the pivoted shank portion of thebottomplate.

Openings 65, similar to the openings 45, are formed in the handle sides for the purpose described and a notch 66 in the bottom wall of the channel provides a convenient means to cut twine or other similar article when the device is in required closed position.

In operation, the spring lever 58 is raised sufiiciently to clear the pin 60 from whichever o ning in the blade holder it may be in, and t en turned on its pivot to engage the other opening, the holder being thus held imthereby.

A similar arrangement of parts is indicated in Figs. 10 and 11, in which a holder 70 of like construction has pivoted in it a blade holder 71 by a pin 72, the same carrying a blade 73 by any preferred means.

The shank of the blade holder has fixed in it a double ended, roundheaded pin 74 adapted to snap into openings 75 in the casing handle, the sides springing to permit such entry and release.

A notch 76 in the back of the handle permits the blade and holder to serve as a convenient protected twine cutter while in closed position.

While certain preferred embodiments of this device have been shown. and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention as defined in the appended claims.

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

1. In a blade holder for receiving and retaining a removable blade with one edge exposed, a main plate, a thickened extension formed on the inner end of the plate, the shoulder formed at the juncture of the plate with the extension being disposed at an angle and being under-cut, a blade clamping plate pivoted at its outer end on the outer end portion of the main plate, the inner end of the clamping plate being cut at an angle coincident with the angular shoulder and bevelled for wedging engagement with the shoulder to secure a blade between the plates.

2. In a blade holder for receiving and retaining a removable blade with one edge eX- posed, a main plate, a thickened extension formed on the inner end of the plate, the shoulder formed at the juncture of the plate with the extension bein disposed at an angle and being under-cut, a lade clamping plate pivoted at its outer end on the outer end portion of the main plate, the inner end of the clamping plate being cut at an angle coincident with the angular shoulder and bevelled for wedging engagement with the shoulder to secure a blade between the plates and coacting means between said plates to secure the clamping plate in a closed position.

3. In a blade holder for receiving and retaining a removable blade with one edge exposed, a main plate, a thickened extension formed on the inner end of the plate, the shoulder formed at the juncture of the plate with the extension bein disposed at an angle and being under-cut, a lade clamping plate pivoted at its outer end on the outer end portion of the main plate, the inner end of the -movably in either a closed or open position clamping plate being cut at a'n angle coincident with the angular shoulder and bevelled for wedging engagement with the shoulder to secure a blade between the plates and coacting means between said plates to secure the clampingplate in a closed position, said last mentioned means comprising a laterall projecting element formed on the main pirate adjacent the shoulder, the adjacent portion`of the clamping plate being formed with arnotch in which said element is adapted to spring.

4. In a blade holder for receiving and retaining a removable blade with one edge exposed, a main plate a thickened extension formed on the linner end of the plate, the

shoulder formed at the juncture of the plate with the extension being disposed atan angle and being under-cut, a blade clamping plate pivoted at its outer end yon the outer end portion of the main plate, the inner end of the clamping plate being cut at an angle coincident with the angular shoulder and bevelled for wedging engagement with the shoulder to secure a blade between the plates and coacting means between said plates to secure the clamping plate in a closed position, said last mentioned means comprising a laterally projecting element formed on the main plate adjacent the shoulder, the adjacent portion of the clamping plate being formed with a notch in which said element is adapted to spring and a lug extending from the clamping plate at a point opposite said notch for facilitating the release of the clamping plate.

5. In a blade holder for receiving and retaining a removable blade with one edge exposed, a main plate, a thickened extension formed on the inner end of the plate, thc shoulder formed at the juncture of the plate with the extension be1ng 'disposed at an angle and being under-cut, a blade clamping plate pivoted at its outer end on the outer end portion of the main plate, the inner end of the clamping plate being cut at an langle coincident with the angular shoulder and bevelled for wedging engagement with the shoulder to secure a` blade between the plates,

and a hollow handle pivotally connected'to 'said extension and adapted to 'receive the blade holder when the latter is not in use.

Signed at New York, in the county of New York and State of New York, this 21st day :of February, 1925.
