Patented Apr. l 22; 1930 A OTTO ALTENBAGH, F OHLIGS-SOLINGEN, GERMANY KNIFE-HAN DLE Application i1ed`May 16, 1928, Serial No. 278,116, and in Great Britai'n October 18, 1927.

This invention relatesto improvements in knife handles of the kind fitted with tools such as screw-drivers, wedges, can openers, for example.

Heretofore such' knives have been made with one or more separately pivoted tools lwhich. fold into the knife handle in a manner similar to the folding blade of a pocket knife, and a sliding ca tch has been provided engaging notches in vthe tools to lock them in the desired positions.

The object of the invention is to provide a knife handle with a series of tools, any one membersof the knife at-one end thereof in such a position that by rotating the member the desired tool may be .brought into position for use, projecting beyond'the knife' han- 36 dle.l Locking means may also be provided forholding the rotary member in the desired 'pos ition. l

Further, a movable cover may befitted for covering the projecting portions of the ro- '55 tary member when the tools are not `in use or the member itself may be so formed that a` separate cover is unnecessary, as hereinafter described. A

v To enable the invention to be fully understood it will now be described by reference to ythe accompanying drawing in which Fig. 1 is a part sectional elevation showing one form of the invention applied to a pocket knife, and l Fig. 42is 'aview vof oneend portion of the knife showing a form of cover. Fig. l3 is a view of one end portion of a knife having a modiiied form of the invention applied thereto, and Fig. 4 is 'a section on line 4 4, Fig. 3, showthe provision of these overlapping edges, it


Referring first to Fig. 1, a single bladed pocket knife 5 is shown, one end of the handle carrying a rotatable member 6 mounted on a 55 pin 7 carried in the handle members of the knife. The member' carries a series of tools 7a, 8, 9, 10, 11, 12, 13 which may include a' glass cutter 7 a, screw driver 8, piercer 9, can or box opener 10, in fact any small tool which is useful when combined with a pocket knife.

By rotating the member 6'any desired tool may be caused to-project beyond theend of the knife handle in position for use as will be readily understood, the spring 14 of the knife blade 15 being cut away or shaped as shown to allow free rotation of the member 6;- Since some of the tools always project beyond the handle and might damage the pocket, a telescoping cover is provided comprising a seriesof nested U-shaped sections 16, 17, 18, 19, 20. The largest section 16 is shown as fastened by rivets 21 to the spring 14, or it may be fastened to the handle mem bers. The smaller telescoping sections as best seen in Fig. 2 are each pivotally movable at their inner ends on a pin 22 and have sector-shaped sides. They can all be turned to nest inside the fixed section 16 and are in that position while the tool is in` use. However, when the knife is to'be carried in the pocket, the cover sections are in the position shown yin Figs. 1 and 2. The smallest section 2C) carriesa snap 23 which projects into a corresponding notch 24 in the upper portion of the knife handle. In order to ensure that the sections will take the circular form illustrated in Fig. 2, and form a continuous guard or cover, they are provided withfoverlapping edges 25, 26. The edge 25 90 extends outwardly and is arranged to contact with the inwardly projecting edge such as 26 of the adjacent, larger'sectlon. Due to is assured that as the smaller section 20 is 95 `extended out ofthe stationary section 16, all

the other movable sections must follow and form the structure shown in-Figs. 1 and 2.

In order to ensure retention of the, movable sections within the section 16, the sides Thus the nested cover sections are held out Aof the way while the tool is in use.

In Fig. 8 an arrangement is shown wherein a separate cover is dispensedfawith, the member 6 being in the form of a wheel with tools formed on a portion of its circumference only, the other portion 27 of the wheel presenting a smooth unbroken curved edge. Thus in thec position shown in Fig. 3, the tools are out of use and the portion 27 projects so that there is nothing to injure the pocket.

For locking the tool carrying members shown in Figs. l and 3 in position, the arrangement shown b est in Figs. 3 and 4 may be employed. A flat spring 28 is secured at one end to the knife handle at 29 and carries a lateral press pin 30 which projects through the knife. The free end of the spring carries a pin 31`Which projects through the adjacent side of the knife handle and is adapted to engage one of'a series of holes 0r recesses 32 formed in the tool member 6 and' thus to lock the member. One hole or recess is provided for each tool carried by the member so that the member may be locked with any desired tool in the operative position.

To unlock the member 6, the projecting end of the press pin 30 is pressed to free the -n 31.

Other locking methods may be devised. By making the pivot 7 of the rotatable may easil be detached and the various tools -sharpene or a fresh membersubstituted.

Having .thus described the nature of my Vsaid-invention and the best means I know of carrying the same into practical eect, I claim 1. A device of the character described, com

prising a pair of spaced side plates forming a handle, a disc mounted for rotation between the side plates, adjacent one end of the latter, said disc having a series of integral tools projecting from its periphery, means for locking the disc with thedesired tool in operative osition and covering means for the ends -ofsaid plates in which said discis mounted,

said covering means being mounted to swing over "said ends on an axis coaxial with the axis of rotation of said disc.

. 2. A device of the character described, ccmprising two spaced side plates forming a handle, adisc mounted for rotation between j the side plates adjacent one end of the latter, said disc having a series of integral tools projecting` substantially radially therefrom, means lfor locking the disc against rotation with the desired tool in operative position and a series of nested U shaped sections having their free ends mounted on a common pivot at the disc-end ofthe handle, the outermost section being fixed to the handle and the other sections being adapted to nest inside the said fixed section. f

3. A device of the character described, coin'- prisingtwo spaced side plates forming a handle; a disc mounted for rotation between the side plates adjacent one end of the latter, said disc having a plurality of tools formed integrally therewith and projecting substantially radially therefrom, spring actuated means carried by one of said plates for securing said disc against rotation with one of said tools in operative position; and means for covering said tools comprising a series of nested U shaped sections having their free ends mounted on a common pivot at the disc end of the handle, one of said U shaped sections being of such a size thatV all the other i ymember in the formof4 a screw, the member f
