JOSEPH 0. HUGHES, F MURPHYSBORO, ILLINOIS.
KNIFE.
Application filed November 8, 1920. Serial No. 422,613.
To all whom it may concern:
Be it known that l, Josnrrr O. HUGHES, a citizen of the United States, residing at Murphysboro, in the county of Jackson and State of Illinois, have invented new and useful Improvements in Knives, of which the following is a specification.
This invention relates to knives, wherein the blade is arranged to slide within the handle and to be wholly concealed when not in use, the invention residing in the con struction, whereby the blade may be held fixed relatively to the handle in any desired position.
The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.
With a view of holding the blade in any deslred position along the length of the handle, I provide the underside of the inturned edges with a plurality of vnotches 16. A leaf spring 18 is terminally secured to the blade l7,the opposite extremity of the spring being curved in the direction of the notches 16, the curved extremity 19 normally engage mg said notches to hold the blade against movement relative to the handle. When it IS desired to project the blade from the handle, the head of the stud is depressed thus moving the curved end of the spring out of engagement with the notches. With the parts so arranged, the blade can be readtill) Wit ily adjusted in either direction and subsequent adjustment the stem is removed from the headed stud whereby the spring moves its curved extremity into engagement with the proper notch to hold the blade in its adjusted position.
A pin 20 extends transversely through the handle adjacent one end thereof, and is disposed with respect to the adjacent terminal of the knife blade to be engaged by the latter and limit the movement of the blade in one direction.
While it have shown the described what i consider the preferred embodiment of the invention, ll desire to have it understood that T do not limit myself to this exact construction, inasmuch as such changes may be resorted to when desired as fall within the sec e of what is claimed.
aving thus described my invention what if claim as new is v l. A knife comprising a handle formed from a single sheet of material having its free. edges spaced to provide a longitudinal slot, a blade arranged for sliding movement within the handle, a stud projecting from the handle through a slot form'anipulating the blade, ahead carried by the stud, cooperating means carried by the blade and handle for holding the blade in different adjusted positions and a lug projecting from one of the said longitudinal edges of the handle to close one end of the slot to limit illtl its longitudinal ed s spaced to define a slot, a knife blade sli able Within the handle, a stud carried by the blade and projectin through the slot, a head carried by the stu notches formed along one of said longitudinal edges, a leaf spring supporting the stud on said blade and having an ofi'set portion adapted to engage said notches for holding the blade in difierent adjusted positions,
meaaea means for limiting the movement of the 10 blade in one direction, and a lug projecting from one of said edges of the handle to close one end of the slot and thereby limit the movement of the blade in the opposite direction.
In testimony whereof I aflix my signature.
JOSEPH O. HUGHES.
