Description

G. R. KENNERLEY KNIFE Filed March 13 1945' GEORCE BRANDALL KENNERLEY y Patented Aug. 2, 1949 UNITED STATES PATENT OFFICE KNIFE Application March 13, 1945, Serial No. 582,541 In Great Britain April 4, 1944 2 Claims. 1 This invention relates to improvements in knives or the like tools especially of the pocket or penknife type.
One object is the provision of a very compact bladed tool particularly suited for carrying in the pocket.
Another object is to effect improved protection of the blade.
A form of the invention consists of a blade, which may have one or two edges, longitudinally displaceable inside a casing with a substantially rectangular opening at one end, the blade being emergeable through said opening. An extension to said blade carries a screw means and complementary screw means constituted by a loose rotary inherently rigid propulsive component is contained within the casing, so that rotation of the propulsive component imparts longitudinal displacement to the blade.
In the drawings:
Figure 1 is a longitudinal section partially in elevation showing the arrangement of parts, with the blade retracted.
Figure 2 is a longitudinal section viewed. at right angles to Fig. 1 but otherwise similar thereto.
Figure 3 is a longitudinal section partially in elevation viewed in the same direction as Fig. 2, but with the blade extended.
Figure 4 is an elevation of the blade, viewed in the same direction as Fig. 1.
Figure 5 is an elevation of the blade, viewed in the same direction as Figs. 2 and 3.
Figure 6 is a detail of the spring washer, viewed in a direction similar to Fig. 1.
Figure 7 is a corresponding end view of the washer.
Figure 8 is a front end view of the case.
Figure 9 is a detail of a plug for transmitting drive to the rotary propulsive component.
Referring to Figs. 1 to 8, a knife blade 10 has a portion Illa forming part of a propelling device; the portion 10a terminates in an obliquely grooved lug lile. The blade is contained in a casing ll, internally cylindrical at I la and having a fiattened tubular portion llc through the end of which blade I is emergeable.
Blade movement is effected by a rotary propulsive component 14 helically wound from hard round bar and resembling (in appearance only) a coil spring, although actually substantially rigid.
A drive plug or spindle I! has an end portion Ila sweated or otherwise attached, to one end of component 14 and has an enlarged diameter portion [1b, a groove l 10 and a groove lld. Plug or spindle I 1 passes through a felt washer I8 located in groove I I0, and thence through a bore in a bush l pressed into the end of the casing.
Dished washer 19, which fits in groove lld, retains the drive plug in correct axial relation to bush l5. Rotation is efiected by a knob (not shown).
In the construction described it will be seen that the blade is restrained from rotation by engagement with the opening 1 lb in the casing through which the blade emerges.
The blade of the knife or the like tool may be a knife blade, a file blade or a saw blade or may be a combination or subcombination of knife, file and saw.
I declare that what I claim is:
1. A bladed tool such as a knife comprising a blade having a longitudinal rearward shank provided adjacent its rear end with a lug, a rigid casing adapted to receive said blade and its shank and having a slot at one end for projection ther through and support of the blade, and a rotatable member formed as a helix axially fixed within said casing and engaging the lug of said shank whereby rotation of said rotatable member will cause projection or retraction of the blade from or into the casing, said rotatable member lying closely within the casing and surrounding the shank so as to serve also as a bearing for the shank and thus for the blade, said lug formed with a slot to receive a portion of a convolution of said rotatable member, the said slot being obliquely inclined to correspond with the obliquity of the convolutions of the rotatable member.
2. A bladed tool such as a knife comprising a blade having a longitudinal rearward flat metal shank of substantially rectangular cross-section provided adjacent its rear end with a lug, a rigid casing adapted to receive said blade and. its shank and having a slot at one end for projection therethrough and support of the blade, and a rotatable member formed as a helix axially fixed within said casing and engaging the lug of said shank whereby rotation of said rotatable member will cause projection or retraction of the blade from or into the casing, said rotatable member lying closely within the casing and surrounding the shank so as to serve also as a bearing for the shank and thus for the blade, the depth of said shank being such as to enable the shank to fit closely within the convolutions of the helical rotatable member.
