FERDINAND NEUHAUS, OF SOLINGEN, PRUSSIA, GERMANY.

POCKET-CUTLERY.

SPECIFICATIQN forming part of Letters Patent No. 337,858, dated Iviarch 16, 1886.

Application filed July 31,1885.

To all whom it may concern:

Be it known that I, FERDINAND NEUIIAUs, a subject of the King of Prussia, residing in Solingen, in the Empire of Germany, have invented a new and useful Improvement in Pocket-Cutlery; and I hereby declare the following to be a full and clear description thereof.

The object of this invention is to produce a new and improved handle,ora combined handle and case, for pocket-cutlery, so that the instrument when closed up is secure against accidental opening, and is also well protected against dust or other injurious contact.

The invention will be readily understood by reference to the accompanying drawings, of which Figure I is an elevation of a knife provided with one of the improved case-handles. In this view the blade is open, and the outer case or cover part of the handle is also partly open. Fig. II is aview similar to Fig. Lexcept that in this figure the blade is closed. Fig. III is a transverse longitudinal elevation of the knife implement, showing the blade open and both parts of the case or handle closed. Fig. IV is a transverse section taken 011 the line m x of Fig.V. Fig. V is asimilar view to Fig. H, except as to a modification ofthe handle,as hereinafter specified. Fig. VI is a transverse section of the handle or casein its closed position, but without the cutter or blade. Fig. VII is a sectional view of the case closed up, and provided with a pair of scissors in lieu of a blade. Fig. VIII is a transverse section of the case in its closed-up position and without any blades in it. Fig. IX shows the case and a pair of scissors in the open position,ready for use. Fig. X is a sectional elevation of the case and scissors opened, and in a partly prepared condition for using.

The said improvement in cutting-instruments consists in forming the handle in two parts, each of which is made in approximately U-shaped form, (in transverse section,) the smaller or inner one of which said halves, a, bears a knife, 8, or scissors, or some other object of use pivoted or hinged thereto, and a similar hinge-like arrangement is made at the other end of the instrument, by which the outer part of the handle I) may be folded up on and inclose the smaller part of the handle Serial No. 173,110. (No model.)

a. Vnen closed, the outer part, b,is held closed upon the inner part, a, by means offrictional contact between the two, so that they cannot accidentally open. 00 is the hinge. The friction can be increased between the two partsa and Z) by an incision, e, as in Fig. I, in the handle a,or by a slit. 6, formed therein, as in Fig. V. By means of this slitting or incision greater elasticity is produced and the inner part of the handle a presses itself more closely against the outer half, 7). Figs. I to VI, inclusive, show different views of the improved device when it is adapted to be used as a knife.

Both halves of the handle of the knife are shown in a and b. a bears the knife 8 on the hinge c or pivot-pin. Both the folding pieces a and b, sprung the one over the other, grasp each other, so that the folding parts cannot open themselves accidentally. On the knife there is a shoulder formed by the notch t', behind which the folding piece I) may be closed up against the blade 8 and secure it in its opened position. In the closed position the knife, &c., is completely protected against the dust. When this handle is to be used with scissors, the shank s of the scissors is pivoted or hinged to the handle a on the pivot or hinge-pin c. The other shank, s, is free from the halves of the handle. Between the shanks of the scissors is placed a spring, f, which acts habitually to open the scissors. The shank s ofthe scissors, when the scissors are folded,rests against the pin a, which is riveted in the half of the handle a.

In order that one may be able to cut conveniently with the scissors, a notch, i, is formed in the shank s of the scissors, and is adapted to be engaged by a pin, 0, on the free half of the handle, and thus a convenient handle for the scissors is formed. The shank 8 may also engage with and be operated by the top of the handle Z) without the pin 0, if so desired.

The operation of using the scissors is as follows: After the handle of the scissors shall have been opened and the scissors themselves shall have been opened into the position for use the operatorbrings the notch i of the shank 8' into engagement with the pin 0, or with the top part of the handle-piece I), and then with the hand embracing the two parts of the handle a b presses them together, thus cutting with the scissors, the spring f acting to throw the scissors open when the pressure of the hand upon the handle is released.

Figs. VIII to X show the device adapted for use as scissors.

when it is Having thus described my invention, what- I claim as new,and desire to secure by Letters Patent, is a .1. The handle-pieces a and b, of approximate U-shaped form, (in transverse section,) united by a hinge, .90, at the opposite end to which the blades are attached, the free end of one of the halves of the handle carrying the cutting-instrument which is hinged thereto, the said cutting-instrument having a notch, t,
