`Applilttion. led Hay 18, 1925. Serial No. 80,963.

r1 his `invention relates to cutlery, and vvhlle it has reference primarily to cuttin instruments, the specification herewith wil indicate my purpose for it to be of a broadinto the handle, the holder being of peculiarl construction adapting it for. receivmg and holding interchangeably tools` and instrum'ents of various designs or for different purposes and particularly a-razor blade of the type or design covered by my co-pending application for safetyrazor led vFebruary 16th, 1923, Serial No. 619,376.

Anotherobject of the invention is to provide a razor blade holding knife having the peculiar facility of quick and easy substitution of another blade `for a dulled or damaged one. I,

A further object of the invention is to provide la cutting tool, the blade of which may be in the nature of a razor blade and having attachments. or guard members applicable to co-operatewith the blade portion of the 'tool for many various purposes, :o such as the channel member to serve as a 4guard for the blade holder to protect the plating thereon and to give the proper slant or angle to the edge of thel blade member during a honing or whetting operation; to

'$5 so shroud or guard` the edge of the blade as to reduce to a minlmum the danger of cutting ones fingers while the instrument is used as a thread or twine cutter; and to provide a guard for adapting the device for 0 use as a razor or analogous device either for usual shaving purposes or fork corn cutting. l

A further Yobject of the invention is to .provide a safety razor blade knife, with special keeper means'forgpreventlng accidental p o5 swinging of the blade holder into or out of the handle and thereby to prevent accidental opening of the knife while belng carried or the accidental closing of the blade while in use. v A still further object of the invention 1s to provide a knife handle and blade holder of .the cheapest possible construction coni lsistent with neatness and efficiency, the same being made preferably of sheet metal and with the metal of each part of uniform thickness. I

Vith the foregoing and other objects in l view the invention consists in the arrangement and combination of parts hereinafter described` and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein,

cally opposite those of the other Without undertaking to enumerate all the various uses or adaptabilities of this devlce as a cutting instrument, there may be noted briefly its adaptability for use as a c1gar cutter, ripper for seams or the like, trimmer for various articles, pencilv sharpener or pointer, a cutter for use by furriers or leather the blade and for use as a holder for the tip of a cigar for clipping or other uses. At one end a hanger or loop 24 is provided and shown as inserted between the point portions of the cheek members. At the vother end the handle is provided with two registering pivot holes 25 and at the eXtreme end two registering notches 26. Inward from the holes 25 or spaced diametrically from the notches 26 are two registering slots 27,. f At the end of the back or rib 22 is a lu 28 bent in the finished form inward from t e rib to form an abutment for the inner end of the blade holder when open. The two cheek portions of the handle are arranged preferably in parallel planes as shown best in Figs. 9 and 10, the space between the planes being suitable to accommodate the blade holder. The blade holder 29 like the handle is made of a .single piece of sheet metal and consists of two symmetrical side members united along a center 30 in respect to which the two side members arebent to finished position as shown in Fig. 4. This device therefore comprises two registering hub or pivot members 31 having two pairs of registering notches 32 and 33, those of one pair being diametriand equally spaced from the pivot holes 34. rlhe metal lmmediately surrounding the holes is struck out as shown at 35 so that these two portions Will abut against each other in the finished holder as shown in Fig. 10 to insure that the tightening of the rivet 42 will not disturb the parallelism of the sides ofthe handle and therefore insure ample space for the holder 29 as it swings into the handle with the blade therein. Fig. 9 shows in dotted lines the relati'on of the holder and blade to the handle when closed. At the point of the holder, the end remote from the hub or pivot, I form two registering holes 36 for a pin 37 which spans closely the spaced ends or oints of the sides of the holder. While the sides a'nd hubportions of the holder lie mainly in two and the back edge 30 vof the menace .of thin metal such as commonly used for safety razor blades. This blade is provided with a notch at either end, shown at 40 at its outer end, suitably spaced' from the back or dull edge of the blade 'to receive the pin 37 while the corner 4l of the blade is Islipped under in the nature of a hook between the pin holder. in so inserting the blade into this-locking position it is held between the thumb and iinger of one hand and at an angle of say 30o to the length of the holder. After the corner 4l is thus hooked under the'pin, the inner or remote end of the blade is swung directly into place in the holder in the'direction of the arrow a of Fig. 5, and the inner corner thereof is forced into frictional gripping engagement between the closely crimped parts of the holder at 38. This portion of' the blade may come directly between. such crimped portionsorit may engage the holder just beyond the crimped portion whereby the crimp willY serve as positive abutment preventing slippinr of the blade endwise toward the rivet 42. ince t-he .main or stem portion of the holder is of equal thickness with the hub portion thereof, the blade 39 approximating in thickness the oifset of the parts35, it will be appreciated that the blade and holderv may swing readily into or out.

of the handle, but the freedom of thismovement may be varied as may be required so that if desired the holder maybe held with sufficient friction within the handle to prevent accidental opening thereof.

To prevent accidental movement of the blade and holder with respect to the handle in either the closed or open position I prefer to employ a, locking keeper 43 in the nature of a U-shaped spring embracing lthe back of vthe handle and having two spaced pins 44 adjacent to the (ends of the legs ject into the slots 27 and thereby the keeper is retained on the handle in permanent position, but adapted to slide lengthwise of the handle as may be permitted by the length of the slots so that the pins may enter the notches 32 to lock the blade open or the notches 33 to lock the blade closed. The

which prokeeper 43 has suiiicient frictional grip upon' the handle to be selflholding in either its locking -position or slipped away from the ivot 42 in unlocking position as shown in ig. 7. f The pins 44 bemg spaced from each other, the blade at 39 passes freely between themas is plain from Fig. 9, but the pins are long enough to enter the notches in the holder hub for the purpose stated.

ing. the

In Fig. 11 I show a nail file 45 having a; notch 40a and a hook portion 41 so designed as to correspond to the notch and hook of the blade, adapting the file for substitution for the blade and use in the same holder.. The back portion 45a of the ile `may be thinner than the main portion thereof if desired for use in the samev holder, but as to this I do not wish to be vunnecessarily restricted.

Fig. 13 shows another alternative, a comb 46 having the same arrangement of notch 40 and hook 41b soas to adapt .it for use in the same holder and locked in place as above described.

Fig. 14 shows a blade guard 47 of channel vor tubular form and adapted to be slipped endwise over the holder 29 which it closely embraces and having at its inner end a pair of ears or extensions 48 carrying locking pins 49 adapted to enter the notches 26 and registering notches 33 of the holder for lockblade and guard in extended position. One side of theguard is extended at 50 to so guard thefblade as to adapt the instrument fornse as a safety shaving razor f or corn cutter. 4In Fig. 16 I show the channel member 51 already referred to for use as a guard for embracing the blade holder while the bladef is being honed or whetted. This member protects the plating." of the4 holder which may be ofA an ornamental nature and gives suliicient thickness thereto to insure a proper inclination or angle for the formation of the bevel of the edge of the blade. This guard is providedwith extensions 52 with locking pins 53 for the same gers from thevblade,

purpose as just described in connection with Fig. l'14. n

Fig. 17 shows a slightly modiied form of guard comprising a channel portion 54 with ears or extensions 55, locking pins 56, and a side extension of skeletonized i nature so formed as to provide a series of loop shaped lingers 57 surrounding loosely or freely the cuttingv edge of the blade. This type of guard protects eectively the operator s finbut admits freely cords; threads, or other' slender objects to come into contact with the blade.

With respect to the keeper -or locking means-for the blade holder` it will be understood that any formV of keeper that -may Acooperate with the notches at the extreme endof the handle, such as are indicated on the various guard members, may be used `either with or without that form of` keeper that is mounted permanently or slidably upon the c handle. If both forms of keepers areused one will reinforce -the other. p

I'claim: 1. The herein described device comprising a handle yhaving two substantially parallel handlev or to be projected 'which an auxiliary keeper is carriedb cheek pieces, a member pivoted-in one end of the handle for swinging to closed or open position, and a keeper servingto lock said member in either its closed or its open position, said keeper being a U-shaped spring device embracing a` portion of the handle and slidable therealong to locking or unlocking position, said handle having a slot through one iside thereof, while the pivotedmember has notches formed therein on opposite sides of its pivot into either rof which'the keeper is adapted to project for locking in either of the two positions specified.

2. The combination with a handle and a holder pivoted in one end thereof for movement into or out of operative position, said handle and holder having registering openings, and a keeper movable toward the pivot `within it, the pivot portion of the holder comprising two parts lying against the inner surfaces of the handle plates and having spacing means between them substantially equal to the thickness of the tool, the spacing means for the pivot portion of the holder consisting of the striking inward of a portion of the holder parts around the pivot.

4. The herein described razor blade knife comprising the combination with a handle,l

a blade holder pivoted in one end of the handle and a blade carried by the holder and adapted to swing therewith into the from the handle, of a guard for the blade slidable over the holder and blade and carrying means at oney end to (zo-operate with the handle to lock the blade and holder in open position.

^ 5. Mechanism as set forth in claim 4 11n t e ar for handle and' co-operates with the e holder reinforcing the means for locking t and blade open. y

6. Mechanism as set forth in claim 4 -in formed on opposite sides of the axis thereof ywhich the end of the holder pivoted to the handle is provided withu a hub hakvlng' erating with said notches for locking the holder in predetermined position. f

In testimony whereof I aix my signature.
